Specification

Rib bow stabilizer after reduction

Technical field

[0001] The present invention relates to a radial arch stabilizer after reduction. More particularly, the present invention relates to a reduced-cost radial arch stabilizer that can stabilize the radial arch after reduction so that it does not move and can maintain the non-powered state in the treatment of fractures of the radial arch.

Background art

One of the facial bone fractures is a radial arch fracture in which the radial arch is broken inward by external force.弓 Fractures of the arch are often in a state where three or four portions of the arch are folded and depressed inward (see Figures 5 and 6).

[0003] Since an important nerve called the facial nerve passes through the outer part of the radial arch, conventionally, reduction of the radial arch fracture has failed to cut open the outer part of the radial arch, and Make a notch near the temple and insert a metal spatula downward between the muscle and fascia to reach the radial arch and push the radial arch outward with the spatula. Is going. In the treatment of fractures of the radial arch, the reduced radial arch is usually not fixed with a tool or the like. Therefore, after reduction, the resting state is maintained until it is connected as it is.

[0004] It should be noted that Patent Document 1 discloses a fractured plywood for aligning and stabilizing a fractured bone, and this document is a diagram in which the radial arch is fixed in a reduced state. Is drawn.

Patent Document 1: Japanese Patent Application Laid-Open No. 63-270044

Disclosure of the invention

Problems to be solved by the invention

[0006] However, the treatment of the above-mentioned radial arch fracture has the following problems.

First, the one using the fractured plywood disclosed in Patent Document 1 becomes a large force that requires general anesthesia such that the operation is performed by peeling the skin of the front half of the face from the top of the head, The burden on patients is large and it is not a realistic treatment method. Therefore, such treatment methods are not usually adopted. Therefore, the former method is often adopted in the treatment of fractures of the radial arch. However, in this case, the reduced radial arch is not fixed by a tool or the like, and it is necessary to maintain a rest until the fracture site is connected. there were.

[0008] In addition, since the fracture site is not fixed, an external force is inadvertently applied, which may cause the normal position of the radial arch to shift. In order to restore the displaced radial arch to its original state, it is necessary to perform the operation again, and further burden the patient.

[0009] Further, in the case of a radial arch fracture, it may be difficult to stably maintain a reduced state depending on how the radial arch is broken, such as the base of the radial arch. In some cases, they were connected without being returned. If they are connected as they are, a dent will be formed in the radial arch, which makes the appearance worse.

[0010] An object of the present invention is to reduce the radial arch after reduction so that the radial arch after reduction can be stabilized so as not to be powered, and the force can be maintained without the power in the treatment of the fracture of the radial arch. It is to provide a stabilizer.

Means for solving the problem

[0011] Means taken by the present invention to achieve the above object are as follows.

In the first invention, a radial arch stabilizer that stabilizes a radial arch that is folded inward so as not to move in a reduced state, and is formed with a recess disposed on the inner side of the radial arch. And a fixed auxiliary body provided with expansion / contraction portions that expand and contract on both sides of the concave portion formation portion, and a working fluid is sent to expand the expansion / contraction portion, or a working fluid is pulled to extract the expansion portion. A fluid control means for contracting the contraction section, and a pipe body that connects the fluid control means and the fixing auxiliary body and allows the working fluid to flow through the inside. This is a radial arch stabilizer.

[0012] The second aspect of the present invention is the radial arch stabilizer after reduction according to the first aspect, characterized in that means for sucking and discharging body fluid is provided.

[0013] (work)

The reduced radial arch stabilizer according to the present invention is used as follows. First, the radial arch that has been folded inward is reduced by a conventional treatment method. Then, the fixation aid is inserted into the gap between the muscle and fascia formed by the instrument used at that time with the expansion / contraction part contracted. While examining the X-ray photograph (imaging), etc., the fixation assisting body is arranged so that the recess forming part corresponds to the radial arch and the inflated and contracted part is provided on the upper side and the lower side corresponding to the inner side of the radial arch.

Next, the fluid control means is operated to send the working fluid to the fixed auxiliary body. In this way, the expansion / contraction part swells, and the radial arch is in a state where the inward force is suppressed by the concave part formation part, and is sandwiched by the expansion / contraction part, and does not move in a reduced state. The force can also be kept stationary.

The radial arch stabilizer according to the present invention is pulled out and removed in a contracted state by drawing the working fluid in the expansion / contraction part.

[0015] A device equipped with a means for sucking and discharging body fluid to the outside of the body sucks the body fluid when body fluid such as blood accumulates around the fixing auxiliary body provided in the body. It can be discharged outside.

The invention's effect

The present invention has the above-described configuration and has the following effects.

(a) According to the radial arch stabilizer after reduction according to the present invention, the radial arch after reduction can be stabilized so that it does not move, and the force can be maintained in that state, so that some external force is applied. However, it is difficult for normal position force to shift. Therefore, the patient can be treated while living in the same way as usual to a certain extent while resting. In other words, the burden on the patient can be reduced in the treatment of the radial arch fracture.

[0017] (b) Further, the reduced radial arch stabilizer according to the present invention can stabilize the reduced radial arch so that it does not move, and the force can be maintained in this state. Even a fracture that is difficult to maintain in a stable state, such as the base of the base, can be prevented from moving before it is displaced after reduction. Therefore, the radial arch stabilizer according to the present invention can be returned to the original state even in the case of such folding.

[0018] (c) The reduced radial arch stabilizer according to the present invention is easy to handle because it is an operation of inflating the expansion / contraction part by sending the working fluid to the fixing auxiliary body by the fluid control means. Follow Thus, the reduced bow arch stabilizer does not require skill in operation.

[0019] (d) A device equipped with a means for sucking and discharging body fluid to the outside of the body sucks the body fluid when the body fluid such as blood has accumulated around the fixing auxiliary body provided in the body. Can be discharged outside the body. Brief Description of Drawings

FIG. 2 is an enlarged explanatory view showing a fixing auxiliary body provided at the tip of the radial arch stabilizer shown in FIG.

FIG. 2 (a) shows a state where the expansion / contraction portion of the fixing auxiliary body is contracted, and FIG. 2 (b) shows a state where the expansion / contraction portion of the fixing auxiliary body is expanded.

[0023] Symbol K indicates the radial arch stabilizer after reduction. The radial arch stabilizer K holds and stabilizes the radial arch B (see Fig. 5 and Fig. 6) folded inward.

[0024] The radial arch stabilizer K connects the fixing auxiliary body 1 provided on the inner side of the reduced radial arch B, the pump device 2 as fluid control means, and the fixing auxiliary body 1 and the pump device 2. It is configured with a tube 3.

The fixing auxiliary body 1 includes an outer tube body 10 and an inner tube body 11 that is inserted into the outer tube body 10 and has a double tube structure. The distal end of the fixing auxiliary body 1 is closed so that the space between the outer tube body 10 and the inner tube body 11 is airtight (or liquid-tight) between the outer tube body 10 and the inner tube body 11, and the inner tube body 11 is opened by the opening portion 13. It is formed to become. A fluid such as air can flow through the gap 14 formed between the outer tube body 10 and the inner tube body 11. The outer tubular body 10 and the inner tubular body 11 constituting the fixing auxiliary body 1 are made of a synthetic resin having deformability, flexibility and stretchability. The

[0026] The outer tube body 10 is provided with a recess forming portion 101 disposed on the inner side of the radial arch B and on both sides of the recess forming portion 101, and the outer shape is deformed by swelling or contracting. Expansion / contraction portions 100, 100a are provided. The recessed portion forming portion 101 is recessed relatively to form a recessed shape when both the expanded / contracted portions 100, 100a are expanded. In the present embodiment, the outer tubular body 10 is formed so that the thickness of the portion corresponding to the expansion / contraction portion 100 is thinner than that of the recessed portion forming portion 101 and other portions, and thereby the outer tubular body 10 and the inner tubular body. When a fluid such as air is sent to the gap 14 of 11, the expansion / contraction portion 100 expands, and the recess forming portion 101 does not deform.

[0027] The pump device 2 controls the expansion / contraction part 100, 100a to be inflated or contracted by feeding or pulling (withdrawing) a fluid from the expansion / contraction part 100, 100a of the fixing auxiliary body 1. . The pump device 2 includes a cylinder member 20 having a cylindrical shape, and a piston member 21 that can reciprocate while being in close contact with the inner wall inside the cylinder member 20, and that sends and pulls fluid to and from the fixed auxiliary body 1. . A short tubular connecting pipe 22 having a small diameter for connecting to the tube body 3 is provided at the tip of the cylinder member 20. In addition, a finger hooking portion 200 for hooking a finger when operating the piston member 21 is formed at the base end portion of the cylinder member 20, and the piston member 21 is pressed against the base end portion of the piston member 21. A finger rest 210 for placing a finger is formed. In the present embodiment, the pump device 2 uses a generally used synthetic resin syringe.

The tubular body 3 has a required length, and is connected to the proximal end portion of the outer tubular body 10 of the fixing auxiliary body 1 in an airtight (or liquid-tight) state. An inner pipe 31 is provided so as to have a double-pipe structure and is connected to the base end portion of the inner pipe body 11 in an airtight (or liquid-tight) state. A fluid such as air can flow through the gap 34 formed between the outer tube 30 and the inner tube 31. The outer tube 30 is in a state in which the inner tube 31 extends a required length from the base end portion of the outer tube 30 which is shorter than the inner tube 31.

[0029] At the base end portion of the outer tube 30, there are branched an inner tube rod passage 320 through which the inner tube 31 passes and an inner tube rod passage 320, and is formed between the outer tube 30 and the inner tube 31. A branch pipe 32 having a flow passage 321 that allows fluid to flow through the gap 34 is connected. The branch pipe 32 is connected so that the distal end portion of the inner pipe rod passage 320 is in an airtight (liquid tight) state with the outer tube 30. The proximal end of 320 is connected to the inner pipe 31 that passes through the inside so as to be airtight (or liquid-tight).

A valve device 33 is attached to the proximal end portion of the flow passage 321. The valve device 33 has a known check valve structure that allows fluid such as air sent from the pump device 2 side to pass in one direction and draw the fluid sent only when operated. The valve device 33 is connected to the connecting pipe 22 of the pump device 2 described above.

[0031] At the proximal end portion of the inner tube 31 that has passed through the inner tube rod passage 320, body fluid and the like can be sucked through the inside of the inner tube 31 from the opening 13 provided at the distal end of the inner tube 11. A connecting portion 310 for connecting a suction device (not shown) as means is provided. A suction device is connected to the connection unit 310.

[0032] (work)

Fig. 3 is an enlarged explanatory view of the main part showing a state in which the fixation assisting body is arranged on the inner side of the reduced radial arch, and the inflated / contracted part is inflated and stabilized so that the radial arch is not powered.

FIG. 4 is an explanatory diagram showing the state shown in FIG.

FIG. 6 is an explanatory diagram showing the fracture state of the radial arch shown in FIG.

In FIG. 4 and FIG. 6, the two-dot chain line (imaginary line) indicates the outline of the face.

[0033] With reference to Figs. 1 to 6, a method and an action for stabilizing the reduced radial arch using the radial arch stabilizer K shown in the present embodiment so as not to move will be described.

First, reduce the radial arch B, which has been folded inward, using a conventional procedure. As described above, the reduction of the radial arch B is made by making a notch in the vicinity of the temple and inserting a metal spatula downward between the muscle and the fascia so as to reach the radial arch B. This is done by pushing the radial arch B outward with a spatula. Radial arch B is then reduced to the state shown in Figs. After reduction of the arch B, pull out the spatula-like instrument.

[0034] Next, the fixation assisting body 1 of the radial arch stabilizer K is inserted into the gap between the muscle and fascia formed by inserting this instrument to the position corresponding to the radial arch B. Fixing auxiliary body 1 is inserted with both expansion / contraction portions 100 and 100a contracted. X-rays (imaging) The recess formation part 101 of the fixation assisting body 1 corresponds to the radial arch B, and the respective expansion / contraction parts 100, 100a are provided on the upper side and the lower side corresponding to the inner side of the radial arch B. Deploy.

The piston member 21 is pushed into the cylinder member 20 in a state where the fixing auxiliary body 1 is disposed at the above position. The cylinder member 20 is filled with air. Thus, air is sent from the valve device 33 and the flow passage 321 to the gap 14 between the outer tube 10 and the inner tube 11 of the fixed auxiliary body 1 through the gap 34 formed between the outer tube 30 and the inner tube 31.

[0036] The fixed auxiliary body 1 has both expansion / contraction portions 100, 100a formed thinner than the other portions by air being sent to the gap 14 between the outer tube body 10 and the inner tube body 11. Inflates to have a spherical shape. Since the inflated and deflated portions 100 and 100a are arranged at positions corresponding to the upper side and the lower side of the radial arch B, the radial arch B is in a state where the inward force is also suppressed by the concave portion forming portion 101. And is sandwiched between both the expanded and contracted portions 100 and 100a. In this way, the radial arch B can be stabilized so as not to move in a reduced state, and the state can be maintained.

[0037] The radial arch stabilizer K is left in the body until the radial arch B is connected to some extent. By leaving the radial arch stabilizer K in the body, a slight space is formed around the radial arch B, and body fluid such as blood accumulates to fill the space. Such body fluids can cause infections and are unsanitary, so it is preferable to remove them from the body.

[0038] In the radial arch stabilizer K, the fixation assisting body 1 and the tubular body 3 have a double-pipe structure, and they are sucked into the connection part 310 of the inner pipe 31 that has passed through the inner pipe insertion passage 320. Since a device (not shown) is provided, the body fluid can be sucked through the inside of the inner tube 31 from the opening 13 formed at the tip of the inner tube 11 and discharged outside the body. In this embodiment, the case where body fluid is sucked through the inside of the inner tube 31 is exemplified. However, as a method of using the inner tube 31, for example, a chemical solution or the like is supplied into the body through the inside. Is also possible.

[0039] The fixation assisting body 1 that has prevented the radial arch B from being driven operates the valve device 33 to draw air from the expansion / contraction portions 100, 100a and contract it, thereby pinching the radial arch B. Release the condition and remove it from the body. [0040] As described above, according to the radial arch stabilizer K, the radial arch can be stabilized so that it does not move in a reduced state, and the force can be maintained in this state, so that even if some external force is applied, it is normal. It becomes difficult to shift from the position. Therefore, the patient can be treated while living in the same way as usual to the extent that he / she is still in a resting state. In other words, the burden on the patient can be reduced in the treatment of the radial arch fracture.

[0041] In addition, the radial arch stabilizer 動力 can be used to drive a fracture that has been difficult to maintain in a stable state, such as the base of the radial arch, and is difficult to maintain after reduction. It can be avoided. That is, the radial arch stabilizer κ can be returned to its original state even in such a folding manner.

[0042] The radial arch stabilizer 操作 is easy to handle because it is an operation that causes the pump device 2 to send air to the fixation assisting body 1 to inflate the expansion / contraction portions 100, 100a. Therefore, the radial arch stabilizer K does not require skill in operation.

In the radial arch stabilizer K shown in the present embodiment, the inner tube 11 and the inner tube 31 are integral, that is, the inner tube 31 is inserted into the outer tube 10 to form the inner tube 11. However, this is not a limitation, and the inner tube 11 and the inner tube 31 can be provided by connecting them separately in an airtight (or liquid tight) state.

[0044] In the present embodiment, the outer tube body 10 and the inner tube body 11 are formed of a synthetic resin, but this is not limited. For example, the material is synthetic rubber or silicon. You can also do it.

In the present embodiment, the outer tubular body 10 is formed so that the thickness of the portion corresponding to the expansion / contraction portions 100, 100a is thinner than the recessed portion forming portion 101 and other portions. The structure of is not limited to this. If a fluid such as air is sent to the gap 14 between the outer tubular body 10 and the inner tubular body 11, the expansion / contraction portions 100, 100a bulge and the concave portion formation portion 101 does not deform. It is also possible to form almost the whole with an inflatable material and provide a member made of a material that does not expand at the required position so that the part does not swell.

[0046] In the present embodiment, the expansion / contraction portions 100, 100a are expanded by the air sent by the pump device 2, but this is not a limitation. If the expansion / contraction portions 100, 100a can be contracted at this time, for example, other gases or liquids can be used. For example, when a liquid contrast agent is used as a means for inflating the expansion / contraction part, the state of the expansion / contraction part 100 can be easily grasped during X-ray imaging. In addition, the pump device 2 for sending the fluid is not limited to the syringe, and a known pump structure can be used.

[0047] The terms and expressions used in the present specification are for explanation purposes only, and are not limited to the features described in this specification and terms equivalent to some of them. There is no intention to exclude the expression. In addition, it goes without saying that various modifications are possible within the scope of the technical idea of the present invention.

Industrial applicability

Even if it is added, the normal position force is difficult to shift. Therefore, the patient can be treated while living in the same way as usual to a certain extent while resting. In other words, the burden on the patient can be reduced in the treatment of the radial arch fracture.

[0049] (b) Further, the reduced radial arch stabilizer according to the present invention can stabilize the reduced radial arch so that it does not move, and the force can be maintained in this state.
