Description

Treatment jig

The present invention relates to a treatment jig for performing a treatment on a bone covered with a mucous membrane such as in the oral cavity using a rotatable shaft having an appropriate treatment function. This application claims priority based on Japanese Patent Application No. 2011-006981 filed in Japan on January 17, 2011, the contents of which are incorporated herein by reference.

Conventionally, in orthodontic correction, a correction method is known in which a specific tooth is fixed, the fixed tooth and the tooth to be moved are connected, and the tooth to be corrected is pulled and moved. In this case, since the teeth are pulled with each other, there is a problem that the fixed teeth also move in the direction of the moving teeth. For this reason, for example, a screw that forms a screw-type implant in which a cylindrical screw part is formed is embedded in the bone of the jaw, and this is used as a fixing source, and a plate or wire is fixed to the screw by fixing means such as brazing. An orthodontic treatment is performed in which ends of the plate and wire are fixed to teeth (see, for example, Patent Document 1).

Patent Document 1 discloses an implant structure in which an anchor head provided with a groove is fixed to the head of an implant body and a screw hole penetrating the anchor head in the vertical direction is provided. In this structure, the implant body is embedded and fixed in the bone of the jaw, the wire with one end fixed to the tooth is locked in the groove, and the screw is screwed into the screw hole. The method of fixing is disclosed.

Japanese Unexamined Patent Publication No. 2004-57729

However, the conventional treatment methods have the following problems.
A screw that is implanted into a bone that is thin and soft and that is not covered by a movable mucosa can be easily fixed manually. However, in the case of a thick and hard bone, a screw cannot be embedded unless a hole is made by drilling. In addition, the mucous membrane covered by the bone to be drilled includes a movable mucous membrane that moves so as to slide along the bone. For this reason, when drilling with respect to this movable mucous membrane, there exists a problem that a mucous membrane will be caught in a drill and the hole larger in diameter than a drill will open or torn in the mucous membrane. To deal with the above problem, in the conventional treatment method, the mucous membrane is first incised, the mucosal flap periosteum is peeled off, and then the thick bone is drilled. In this case as well, there is a problem in that it is accompanied by postoperative swelling and pain because open surgery is performed.

Also, after the drill hole is opened in the bone, the position of the drill hole of the mucosa and the bone may shift due to the sliding of the mucosa with respect to the bone. Therefore, when a screw is screwed into a previously drilled hole, the screw does not enter the drill hole drilled in the bone according to the position of the mucosal hole, and the operator searches for the drill hole opened in the bone. There is a problem that arises.

The present invention has been made in view of the above-described problems, and can drill a bone without involving the mucous membrane and prevent the position of the hole between the mucous membrane and the bone after drilling from shifting. An object of the present invention is to provide a treatment jig that can be used.

In order to achieve the above object, one embodiment of a treatment jig according to the present invention is a treatment jig for performing a treatment on bone covered with a mucous membrane, comprising: a frame main body; and a distal end portion of the frame main body. And a sharpened tip that protrudes.

In the present invention, when the screw is embedded in the bone covered with the mucous membrane in the oral cavity by the treatment such as orthodontic treatment by the implant, the mucous membrane is pierced so as to reach the submucosal bone at the sharpened portion of the treatment jig, and the frame body Then, the mucous membrane is pressed against the bone, and a drill hole can be formed in the bone together with the mucosa using the drill in the pressed state. Thereafter, a screw can be screwed into the drill hole using a screwdriver. At this time, the mucous membrane is brought into close contact with the bone by being pressed by the sharpened portion. This prevents the mucous membrane from sliding along the bone surface.
Then, by sliding a hole in the bone together with the mucosa by drilling in the vicinity of the position where the mucosa is pressed against the bone by the frame body, the sliding of the mucosa with respect to the bone is regulated. For this reason, it can prevent that a mucous membrane is caught in the rotating drill.

Even after drilling, the pressing by the sharpened portion is maintained. Thereby, it can prevent that the position of the drill hole opened to the mucous membrane and the bone after that shift | deviates.
This eliminates the need for troublesome operations such as positioning with respect to the drill hole that has been opened in advance while aligning the hole between the mucous membrane and the bone while maintaining the pressed state by the sharpened portion. As a result, the screw can be easily embedded in the drill hole.

In the treatment jig according to the present invention, the frame body may include a guide portion that guides a rotatable shaft having an appropriate treatment function so as to be rotatable about the shaft axis and movable in the shaft axis direction. preferable.
In this case, the mucous membrane is pierced with the sharp part of the treatment jig, and the shaft (first shaft) having a drill function is engaged with the guide part while the mucous membrane is in close contact with the bone and pressed with the frame body. The drill hole can be formed by moving one shaft toward the mucous membrane (bone) side while rotating. Next, the first shaft engaged with the guide portion is replaced with another screwdriver-type shaft (second shaft) capable of screwing the screw, and the second shaft is rotated to the mucous membrane (bone) side. A screw can be screwed into the drill hole by moving it toward.
At this time, since the sharpened portion and the guide portion are provided on the frame main body, the position of the rotation axis of the shaft engaged with the guide portion is in the vicinity of the position where the mucous membrane is pressed against the bone by the sharpened portion. Therefore, when a hole is made in the bone together with the mucous membrane by drilling, the mucous membrane in which the sliding with respect to the bone is restricted is less likely to be caught in the rotating drill (first shaft).

Also, since the position of the drill hole does not shift, it is possible to replace the guide portion with another shaft while maintaining the pressed state by the frame body. In addition, it is not necessary to perform a troublesome operation such as positioning the drill hole that was previously opened and aligning the hole between the mucous membrane and the bone, and the drill hole can be obtained using another shaft (second shaft) of the replaced driver type. The screw can be embedded easily.

In the treatment jig according to the present invention, it is preferable that the guide portion engages a plurality of shafts so that the shafts can be guided, and the shaft axes of the shafts are arranged in parallel to each other.
In this case, a plurality of drill holes can be drilled in the bone using the plurality of shafts simultaneously at that position without moving the frame body in a state where the mucous membrane is pressed against the bone by the sharpened portion. Further, the distance between the shafts can be set small and accurately in parallel.

Further, in the treatment jig according to the present invention, the frame main body is formed of a flat plate member, and a guide concave groove extending in the shaft axial direction of the shaft guided by the guide portion along the plane of the frame main body is provided. More preferred.
In this case, the shaft guided along the guide portion can be further moved along the guide groove. For this reason, there is no blur due to the movement of the shaft, the accuracy can be improved, and the position of the rotating shaft of the shaft can be maintained even when the shaft is replaced with another shaft having another function.

In the treatment jig according to the present invention, it is preferable that the sharpened portion is provided at positions on both sides of the shaft guided by the guide portion in plan view.
In this case, the mucous membrane is pressed against the bone with the same force with a good left-right balance on both sides of the shaft. For this reason, the pressing force of a part of the mucous membrane around the shaft is not insufficient, and the mucous membrane can be reliably prevented from being caught in the drill (shaft).

According to the treatment jig of the present invention, drilling can be performed on the basis of the frame main body in a state where the sharpened portion pierced with the mucous membrane is supported by the bone and the mucous membrane is pressed against the bone. At this time, since sliding between the mucous membrane and the bone is regulated, drilling on the bone can be performed without involving the mucous membrane. This eliminates the need for conventional open surgery in the case of thick and hard bones, and eliminates post-operative swelling and pain due to the open surgery.
Further, by maintaining the pressed state by the sharp point in the frame body, it is possible to prevent the positions of the holes of the mucous membrane and the bone from being shifted after drilling. Also, when performing a treatment such as screwing a screw into a drill hole formed in a bone, the operator does not need to search for the drill hole, and work efficiency can be improved.

The handpiece 2 includes a power source (not shown), has a gripping portion 21 on the proximal end side, and is provided with a holding portion 22 that detachably holds the shaft 3 on the distal end side of the gripping portion 21. The handpiece 2 is configured to rotate the shaft 3 at a predetermined rotational speed by a power source supplied from the outside.

In the present embodiment, as the shaft 3, a drill-type first shaft 3 </ b> A for opening a hole for the screw 4 (see FIGS. 9C and 9D) in a bone (a bone of a jaw part in the oral cavity), and a first shaft A screw-type second shaft 3B for attaching the screw 4 to be inserted into the hole opened by 3A to the tip is used.
1 to 3B and FIG. 7 show a state where the first shaft 3A and the second shaft 3B are attached to the treatment jig 1. FIG.

As shown in FIGS. 4 to 8, the treatment jig 1 includes a frame body 10 having a guide piece 12 (guide portion) that guides the shaft 3 so as to be rotatable about the shaft axis and movable in the shaft axis direction; A plurality of (four in this case) protruding

needles

11, 11,... (Pointed portions) protruding from one end portion 10 a in the longitudinal direction of the frame body 10 are schematically configured.

In the present embodiment, the longitudinal direction of the frame body 10 is referred to as a frame axis, the protruding needle 11 side along the frame axis is referred to as a distal end side, and the opposite side is referred to as a proximal end side. In addition, a direction perpendicular to the frame axis in the surface direction of the frame body 10 is referred to as a width direction, a plane on the inner angle side of the refracted frame body 10 is referred to as an inner surface, and a plane on the opposite side is referred to as an outer surface.

The frame main body 10 is made of a material such as stainless steel and is made of a flat plate member having two refracting

portions

10b and 10c that are located at intervals in the longitudinal direction. The frame body 10 includes a shaft holding portion 10A located on the distal end side from one of the first refracting portions 10b on the distal end side, and a gripping portion 10B located on the proximal end side relative to the first refracting portion 10b. The grip portion 10B has a mountain shape that is refracted toward the inner surface by the other second refracting portion 10c at an intermediate position in the frame axis direction.
The shaft holding portion 10A is formed with a step portion 10d at an intermediate portion in the frame axial direction, and a portion on the distal end side (reference numeral 10e) from the step portion 10d is also an outer surface than a portion on the proximal end side (reference number 10f). Located so as to project to the side.

A guide piece 12 for holding the two shafts 3 movably along the frame axial direction is provided on the outer surface of the portion 10f on the base end side with respect to the stepped portion 10d. In addition, a pair of

guide grooves

13 and 13 extending in the axial direction of the shaft so that the two shafts 3 guided by the guide pieces 12 in the plane are along the outer surface of the portion 10e on the tip side of the step portion 10d. Is provided.

The guide piece 12 simultaneously guides the two

shafts

3 and 3 along the shaft axial direction, and a pair of receiving

portions

12a and 12a (see FIG. 6 and FIG. 8). Each receiving portion 12a is a curved surface corresponding to the outer diameter of the shaft 3, and has a concave shape with a part thereof being an opening.

Of the two types of shafts 3 used in the present embodiment, the outer diameter of the drill-type first shaft 3A is larger than the opening width of the receiving portion 12a. That is, the first shaft 3A is configured such that it cannot be movably engaged on the inner peripheral surface side of the receiving portion 12a unless it is inserted from above the receiving portion 12a. In the case of the first shaft 3A, in order to provide a hole at a certain position by supporting it with the guide piece 12 for drilling at a desired drilling position so that the drill tip does not slip even if there is a slope of bone. is there.
On the other hand, in the case of the driver-type second shaft 3B, it is screwed into the hole formed by the first shaft 3A so as to be held by the guide piece 12 with the screw held at the tip of the shaft. Therefore, the outer diameter is smaller than the opening width of the receiving portion 12a. As a result, the second shaft 3B can be inserted into the receiving portion 12a from the side of the guide piece 12, and a play that can be moved with respect to the receiving portion 12a is provided.

The size of the step of the step portion 10d and the positions of the guide piece 12 and the guide groove 13 are determined when the holding portion 22 of the handpiece 2 is in a state where the shaft 3 is engaged with the receiving portion 12a of the guide piece 12. The engagement is not hindered by the outer surface of the portion 10f on the base end side with respect to the stepped portion 10d.

The plurality of protruding needles 11 are provided in a state in which the needle tip 11a (see FIG. 5) is directed in the frame axial direction at the distal end portion 10a of the shaft holding portion 10A, and each guide concave groove is viewed from the distal end side shown in FIG. One is disposed on each side of 13 and is disposed at a certain interval in the width direction of the frame body 10.

Next, the usage method and operation of the treatment jig 1 described above will be described with reference to the drawings.
As shown in FIG. 1 to FIG. 3B, FIG. 9A, and FIG. 9B, when the screw 4 is embedded in the bone 6 covered by the mucous membrane 5 in the oral cavity by treatment such as orthodontic treatment with an implant, The mucous membrane 5 is pierced with the protruding needles 11, 11,... Until it reaches the bone 6 below the mucous membrane 5, and the mucous membrane 5 is brought into close contact with the bone by pressing the tip 10 a of the frame body 10 and pressed in the direction of the arrow X 1. This prevents the mucosa 5 from sliding along the surface of the bone 6, thereby fixing the position.
Then, as shown in FIG. 9C, the first shaft 3A having a drill function is engaged with the guide piece 12 (FIG. 1 or the like) in the pressed state, and the mucosa 5 (bone) is rotated while rotating the first shaft 3A. 6) A drill hole 6a is formed in the bone 6 together with the mucosa 5 by moving toward the side (arrow X1 direction).

Next, as shown in FIG. 9D, the first shaft 3A engaged with the guide piece 12 is replaced with another screwdriver-type second shaft 3B capable of screwing the screw 4, and the second shaft 3B is rotated. The screw 4 can be embedded in the bone 6 by screwing the screw 4 into the drill hole 6a by moving toward the mucosa 5 (bone 6) side (arrow X1 direction).

The projecting needle 11 and the guide piece 12 are provided on the frame body 10. For this reason, the position of the rotation axis of the shaft 3 engaged with the guide portion is in the vicinity of the position where the mucosa 5 is pressed against the bone 6 by the protruding needle 11. Therefore, when the drill hole 6a is opened in the bone 6 together with the mucosa 5 by drilling, the mucosa 5 in which the sliding with respect to the bone 6 is restricted is not easily caught in the rotating drill (shaft 3).

Also, even after drilling, the pressing by the protruding needle 11 is maintained. Thereby, it can prevent that the position of the drill hole 6a opened to the subsequent mucous membrane 5 and the bone 6 shifts | deviates.

Further, the guide piece 12 is replaced with another second shaft 3B while maintaining the pressed state by the protruding needle 11. This eliminates the troublesome work of positioning with respect to the previously drilled hole 6a and aligning the hole between the mucous membrane and the bone. As a result, the screw 4 can be easily embedded in the drill hole 6a by using another second shaft 3B of the replaced driver type.

Further, the guide piece 12 engages the two shafts 3 so that they can be guided, and the shaft axes of the

shafts

3 and 3 are arranged in parallel to each other. For this reason, without moving the frame main body 10 in a state where the mucous membrane 5 is pressed against the bone 6 by the protruding needle 11, the two shafts 3 are simultaneously used at the position to open the two drill holes 6 a in the bone 6. Can do. In addition, the distance between the

shafts

3 and 3 can be small and accurately provided in parallel.

Furthermore, in this treatment jig 1, a guide groove 13 is provided in the frame body. For this reason, the shaft 3 guided along the guide piece 12 can be further moved along the guide groove 13. Therefore, there is no blur due to the movement of the shaft 3, and the accuracy can be increased. Moreover, even if it replaces with the shaft 3 which has another function, the position of the rotating shaft of the shaft 3 can be maintained.

Furthermore, the protruding needles 11 are provided at positions on both sides of the shaft 3 guided by the guide piece 12 in plan view. Therefore, the mucous membrane 5 is pressed against the bone 6 with the same force with good balance on both sides of the shaft 3. As a result, the pressing force of a part of the mucous membrane 5 around the shaft 3 is not insufficient, and the mucosa 5 can be reliably prevented from being caught in the drill (shaft 3).

As described above, in the treatment jig according to the present embodiment, the protruding needle 11 that has pierced the mucous membrane 5 is supported by the bone 6, and the shaft 3 is mounted on the basis of the frame body 10 in a state in which the mucosa 5 is pressed against the bone 6. Rotate around the shaft axis and move in the axial direction. Thereby, the sliding of the mucous membrane and the bone is regulated. For this reason, drilling with respect to the bone 6 can be performed without involving the mucous membrane 5.
As a result, incision surgery that has been conventionally performed in the case of thick and hard bones is unnecessary, and postoperative swelling and pain due to the incision surgery can be eliminated.

Further, by maintaining the pressed state by the protruding needle 11 in the frame body 10, it is possible to prevent the positions of the holes of the mucosa 5 and the bone 6 from being shifted after drilling. Thus, even when the guide piece 12 is replaced with another shaft 3 (second shaft 3B) and the drill hole 6a opened in the bone 6 is treated, there is no need for the operator to search for the drill hole 6a. , Work efficiency can be improved.

As mentioned above, although embodiment of the treatment jig by this invention was described, this invention is not limited to said embodiment, It can change suitably in the range which does not deviate from the meaning.

For example, in the treatment jig 1 of the present embodiment, the two shafts 3 can be engaged with the guide pieces 12, but the number of the corresponding shafts 3 is not limited.
For example, as shown in FIGS. 10 and 11, an intraoral treatment jig (treatment jig 1 </ b> A) according to a modification includes a second guide piece 14 (guide part) that can engage one shaft 3 in the frame body 10. The guide holding groove 13 is formed at one location in the center in the width direction of the shaft holding portion 10A. In the treatment jig 1A, the receiving portion 14a of the guide piece 14 is provided at one position in the center in the width direction as shown in FIGS. 12A and 12B. 12A shows a state where the drill-type first shaft 3A is engaged with the guide piece 14, and FIG. 12B shows a state where the driver-type second shaft 3B is engaged with the guide piece 14. The protruding needles 11 provided at the distal end portion 10a of the frame body 10 are provided at positions on both the left and right sides of the shaft 3 guided by the guide concave groove 13.

In the treatment jig 1A according to the present modification, the shaft 3 is rotated around the shaft axis with the frame body 10 in a state where the mucous membrane is pressed against the bone by the two protruding needles 11 as in the above-described embodiment. Since it can be moved in the axial direction of the shaft, drilling can be performed on the bone without involving the mucous membrane (see FIGS. 9A to 9D).
Further, by maintaining the pressed state by the protruding needle 11 in the frame body 10, it is possible to prevent the positions of the drill holes opened in the mucous membrane and the bone after drilling from being shifted. This also improves the working efficiency when the practicing operator does not need to search for the drill hole even when the guide piece 14 is replaced with another shaft 3 and the drill hole opened in the bone is treated. Can do.

In the treatment jig 1 of the present embodiment, the case where the screw 4 based on the orthodontic treatment is embedded in the bone is an application target. However, the treatment jig 1 is not limited to the treatment by the orthodontic treatment described above. There are no restrictions on the application.
Also in the shaft 3, the shaft 3 having two types of functions of the drill type (first shaft 3A) and the driver type (second shaft 3B) is employed in the present embodiment, but has other functions. It is also possible to apply to a shaft.

Furthermore, in the present embodiment, the frame body 10 is provided with the guide portion, but the present invention is not limited to this, and the guide portion may be omitted. In this case, the drill or the like is not guided by the guide portion. However, it is possible to maintain the pressed state by the frame body 10. For this reason, the effect of preventing the positional deviation of the drill hole opened in the mucous membrane and the bone can be obtained.

In the present embodiment, the frame body 10 has a flat plate shape and has two refracting

portions

10b and 10c. However, the frame 10 is not limited to the shape described above.
Further, the configuration of the protruding needle 11 such as the shape, the protruding dimension, and the interval can be set as appropriate, and may be a fork shape that is formed integrally with the frame body 10.
Furthermore, although the guide groove 13 is formed on the outer surface of the shaft holding portion 10A of the frame body 10 in the present embodiment, the guide groove 13 may be omitted.

Furthermore, in this embodiment, as a method of using the treatment jig 1, the protruding needle 11 is penetrated with respect to the mucous membrane 5 and the tip thereof reaches the bone 6 to be supported. When larger than 11, the protruding needle 11 does not penetrate completely. Also in this case, the treatment jig 1 can be used. In this case, by pressing against the bone 6 through the mucous membrane 5 by the pressing force of the frame body 10, the supporting force becomes smaller than when the tip of the protruding needle 11 is stuck in the bone 6. However, it is possible to suppress the sliding of the mucosa 5 with respect to the bone 6 and obtain the same effect.

In addition, it is possible to appropriately replace the constituent elements in the above-described embodiments with known constituent elements without departing from the spirit of the present invention.

According to the treatment jig of the present invention, drilling can be performed on the basis of the frame main body in a state where the sharpened portion pierced with the mucous membrane is supported by the bone and the mucous membrane is pressed against the bone. Since sliding between the mucous membrane and the bone is regulated, the bone can be drilled without involving the mucous membrane. Further, in the case of thick and hard bones, the conventional incision operation is not required, and postoperative swelling and pain due to the incision operation can be eliminated. In addition, since the pressed state by the sharpened portion is maintained in the frame body, it is possible to prevent the positions of the holes of the mucous membrane and the bone from being shifted after drilling. In addition, when performing treatment such as screwing a screw into a drill hole opened in a bone, the treatment can be performed without performing an operation of searching for a drill hole, and as a result, work efficiency can be improved. it can.
