Description

FIXING METHOD OF LIVING TISSUE, TUBE-TYPE NEEDLE PACKAGE AND USING METHOD THEREOF

The present invention relates to a fixing method of living tissue, a tube-type needle package and a using method thereof, and more particularly, to a method of elastically fixing living tissue into living skin, a tube-type needle package and a using method thereof.

If a graft material, such as fat, is inserted into a frequently moving part of a muscle of an experimental animal, particularly, a rabbit, a mouse, a beagle that frequently moves, etc., in particular, into a part around the mouth, the neck, and the limbs, the movement of the inserted graft material is serious. Therefore, the graft material irregularly receives strong pressure and thus spreads widely or exits from the experimental animal.

In a direction in which strong tension occurs during a healing period, normal healing is not achieved, but a fiber cell excessively proliferates and bleeding is induced. Therefore, unexpected side effects, hematoma, or calcification may occur.

In order to prevent the graft material from spreading widely or exits from the experimental animal, a method of elastically fixing living tissue around the graft material has been suggested. In more detail, methods of elastically fixing tissues outside or inside a living tissue are known.

Among the methods, the method of elastically fixing tissues outside a living tissue may be performed using a gamete or splint, a cast, a tape, or the like. However, this method has a weak fixing force and a difficulty in limiting a desired part.

Also, in the method of elastically fixing tissues inside a living tissue, the tissues are fixed to a peripheral tissue in an incised state using a suture. However, an experiment time may increase, an unexpected reaction may occur during a healing process of the incised part after the incision, and external germs may penetrate into the living tissue through the incised part. In addition, it is difficult to find particular fixing positions from a neck and rhizomelic portions when cutting the neck and the rhizomelic portions.

An animal experiment is a process that requires the largest cost and time in most bioresearches for developing graft materials. If only one of the experimental animals causes an error, outrageous costs are incurred, a direction of a research result is different from the fact. Therefore, a ripple effect cannot be calculated.

The present invention provides a fixing method of a living tissue by which a fixing force can be increased and a fixing position can be easily found, and a tube-type needle package and a using method thereof.

According to an aspect of the present invention, there is provided a fixing method of a living tissue by which a tube-type needle package is inserted into living skin of an animal to fix first and second fixing tissue parts of the living skin to each other, the method including: inserting a tube-type needle into the living skin, wherein a suture including adhesive projections has been inserted into the tube-type needle, and the adhesive projections have been formed on a surface of the suture; thrusting the tube-type needle into the living skin so that an end part of the inserted tube-type needle is located up to the first fixing tissue part of the living skin and forcing an end of the suture to adhere to the first fixing tissue part; moving the tube-type needle back and forth so that the suture, the end of which has adhered to the first fixing tissue part, extends in zigzags in a direction approximately horizontal with respect to an insertion direction of the tube-type needle inside the first fixing tissue part so as to adhere to the first fixing tissue part; and moving the tube-type needle to the second fixing tissue part so that the suture adheres to the second fixing tissue part.

The tube-type needle may be moved back and forth three or more times.

At least two or more sutures may be inserted into the tube-type needle.

According to another aspect of the present invention, there is provided a tube-type needle package including: a tube-type needle which includes an end having a probe shape and a connecting hole connecting the end to an other end thereof; a suture which is inserted into the connecting hole of the tube-type needle and includes adhesive projections which are formed on a surface thereof; and a handpiece which includes a body part and a pushing member, wherein the body part is removably combined with the other end of the tube-type needle and inserts the suture thereinto, and the pushing member pushes the suture through the tube-type needle to the outside and is supported by the body part.

Two or more sutures may be inserted in to the tube-type needle.

The pushing member may include a pair of rollers which face each other to locate the suture therebetween and rotate in contact with the suture to push the suture from the tube-type needle.

One of the rollers may be combined with the body part to be elastically biased toward the other one.

The pushing member may include: a sliding surface which extends in a longitudinal direction of the suture and on which the suture is put; and a sliding means which is opposite to the sliding surface so that the suture is located between the sliding means and the sliding surface, is combined with the body part to slide in the longitudinal direction of the suture, and moves in contact with the suture put on the sliding surface to push the suture from the tube-type needle.

The sliding means may include an entering part which is formed at the sliding means and has a shape corresponding to the end of the tube-type needle to be inserted into the end of the tube-type needle, wherein the tube-type needle moves with a sliding movement of the sliding means.

The pushing member may include: a driven roller which rotates in contact with the sliding means; and pushing rollers which receive a rotation force of the driven roller to rotate, insert the suture therebetween, and include a unidirectional gear which rotates with the driven roller only if the driven roller rotates in one direction.

The sliding means may be flexibly supported by the body part to be elastically biased toward the sliding surface.

The handpiece may include a slot which is formed in the handpiece in a direction perpendicular to the longitudinal direction of the suture, wherein the suture is inserted into the slot in a direction perpendicular to the longitudinal direction of the suture.

The end of the tube-type needle may have a blunt cross-sectional shape to reduce friction occurring on a contact surface between the tube-type needle and the suture when the suture is pushed from the tube-type needle.

According to another aspect of the present invention, there is provided a method of using the tube-type needle package, including; inserting the tube-type needle into which the suture has been inserted, ; when an end of the suture is fixed to a desired part inside the living skin, moving the tube-type needle to another part to push the suture from the tube-type needle so that the suture adheres to the living skin; and when the tube-type needle is removed to a desired part, operating the pushing member to push the suture outside the tube-type needle so that the suture adheres to the desired part in zigzags.

When the suture adheres to the living tissue through this method, the suture firmly adheres to the first fixing tissue part, thereby securing a fixing force. Thus, even if a graft material is inserted into a frequently moving part, the graft material may be prevented from being damaged.

The above and other features and advantages of the present invention will become more apparent by describing in detail exemplary embodiments thereof with reference to the attached drawings in which:

A fixing method of a living tissue according to an exemplary embodiment of the present invention will now be described in detail with reference to the attached drawings.

The fixing method of a living tissue according to the present invention involves to insert a living tissue into a living skin S of an animal and fix the living tissue between first and second fixing tissue parts A1 and A2 of the living skin S. Also, in this method, a suture 20, which has been inserted into a needle 10, is inserted through a small incised part of the living skin S to fix the first and second fixing tissue parts A1 and A2 to each other inside the living skin S.

The first fixing tissue part A1 may be any part which requires an operation, in particular, may be a peripheral tissue part of a graft material C if the graft material C is inserted.

The second fixing tissue part A2 may be a part which is opposite to the first fixing tissue part A1 so that the graft material C is located between the first and second fixing tissue parts A1 and A2. However, the present invention is not limited thereto, and the second fixing tissue part A2 may be any tissue inside the skin which is to be fixed with the first fixing tissue part A1. The first fixing tissue part A1 may be a local part or a slightly broad part, and this also applies to the second fixing tissue part A2.

This fixing method includes first through fourth operations.

FIGS. 2A through 2F are views illustrating a fixing method of a living tissue, according to an exemplary embodiment of the present invention.

In the first operation, the needle 10 into which the suture 20 has been inserted is inserted into the living skin S, wherein adhesive projections 21 are formed on a surface of the suture 20.

In the second operation, the needle 10 is thrust into the living skin S so that an end part of the needle 10 is located up to the first fixing tissue part A1 and an end part of the suture 20 adheres to the first fixing tissue part A1.

In the third operation, the needle 10 is moved back and forth so that the suture 20, the end part of which has adhered to the first fixing tissue part A1, adheres to the first fixing tissue part A1 in zigzags which extend in the first fixing tissue part A1 in a direction horizontal with respect to an insertion direction of the needle 10.

In the fourth step, the needle 10 is moved to the second fixing tissue part A2 so that the suture 20 adheres to the second fixing tissue part A2.

In more detail, as shown in FIG. 2A, the needle 10 is thrust up into the desired first fixing tissue part A1, and the end part of the suture 20 adheres to the first fixing tissue part A1. As shown in FIG. 2B, the needle 10 is moved back to a predetermined range so that the suture 20 is pushed from the needle 20. As shown in FIG. 2C, the needle 10 is re-thrust by movement in a direction approximately horizontal with respect to the insertion direction thereof. Also, the needle 10 is moved in an approximately slanting direction so that the suture 20 is fixed to the living tissue in approximately a V shape.

As shown in FIGS. 2D and 2E, the above-described steps are repeated so that the needle 10 is moved back and forth slantingly. As a result, the suture 20 adheres to the first fixing tissue part A1 in zigzags.

After a sufficient fixing force is secured in the first fixing tissue part A1, the needle 10 is moved back so that the suture 20 adheres to the second fixing tissue part A2 as shown in FIG. 2F.

If the suture 20 adheres to the living tissue through this method, the suture 20 firmly adheres to the first fixing tissue part A1, thereby securing a fixing force. Thus, even if a graft material is inserted into a frequently moving part, the graft material may be prevented from being damaged.

A graft material fixed into a living tissue through this method is shown in FIG. 1. Referring to FIG. 1, a fixing method is used to fix a suture to the first fixing tissue part A1 in zigzags and the other suture to the second fixing tissue part A2 in zigzags.

In the third operation, a needle may be moved back and forth at least three times or more to provide a firm fixing force so that a suture firmly adheres to a fixing tissue part.

A single suture may be inserted into the needle, but the present invention is not limited thereto. Therefore, as shown in FIG. 3, two or more sutures may be inserted into one needle. If several sutures are inserted into one needle as stated above, a more firm fixing force may be provided as shown in FIG. 4. In particular, a whole thickness of two or more sutures may be made thinner than a thickness of a single suture so that the sutures inserted into a skin tissue are not easily visible from the outside.

A tube-type needle package according to an exemplary embodiment of the present invention will now be described with reference to FIGS. 5 through 7.

FIG. 5 is a side view illustrating a tube-type needle package according to an exemplary embodiment of the present invention. FIG. 6 is a front view of the tube-type needle package of FIG. 5;

The tube-type needle package according to the present embodiment includes a tube-type needle 10, a suture 20, and a handpiece 30.

The tube-type needle 10 may be formed of a metal material which is harmless when inserted into a living tissue. Here, an end 10a of the tube-type needle 10 has a probe shape, and an other end 10b of the tube-type needle 10 has a shape with a diameter that widens in a longitudinal direction. A connecting hole 11 is formed inside the tube-type needle 10 to connect the end 10a and the other end 10b to each other.

The suture 20 is inserted and fixed into the connecting hole 11 of the tube-type needle 10. In more detail, the suture 20 as a whole has a thread shape, and a plurality of adhesive projections 21 having thorn or leaf shapes are formed on a surface of the suture 20. The adhesive projections 21 strengthen an adhesive force with respect to a living tissue of the human body and may have a directivity to be hung and fixed on the living tissue in only one direction. The suture 20 may be a single suture or two or more sutures to secure a more firm fixing force.

The adhesive projections 21 may have a unidirectional property or bidirectional property. For example, the adhesive projections 21 may be variously designed according to operation conditions to have one directional property in a partial section and another directional property in another section.

The suture 20 may be formed of various materials to maximize an adhesive force with human tissue and secure a strong elastic force and a strong supporting force. In more detail, the suture 20 may be formed of nylon, polypropylene, polydioxanon, polycarprolacton, poly-L-lactic acid (PLLA), polyglycolic acid (PGA), poly-lactic-glyolic acid (PLGA), cat gut, gold (Au), an alloy including Au, platinum (Pt), an alloy including Pt, titanium (Ti), or an alloy including Ti.

The handpiece 30 is removably combined with the other end 10b of the tube-type needle 10, and the suture 20 is inserted into the handpiece 30. Also, the handpiece 30 operates as a suture pushing aid which includes a pushing member 32, which pushes the suture 20 from the needle 10 to the outside.

The handpiece 30 includes a body part 31 and the pushing member 32. The body part 31 includes an entering part 311, which has a shape corresponding to the other end 10b of the tube-type needle 10 to be inserted into the other end 10b of the tube-type needle 10, and a supporting part 312, which forms a single body with the entering part 311, and support rollers 321. A supporting plate 313 is formed at the supporting part 312 to be pivotably combined with the supporting part 312. The supporting part 312 and the supporting plate 313 are connected to each other through an elastic spring 314 which forces the supporting plate 313 to be always in a position determined with respect to the supporting part 312. A slot 311a is formed in the entering part 311 in a direction perpendicular to a longitudinal direction of the suture 20. Thus, the suture 20 is inserted in to the slot 311a in a direction perpendicular to the longitudinal direction of the suture 20.

The pushing member 32 includes the pair of support rollers 321 which are installed to face each other so that the suture 20 is located between the support rollers 321 of the pushing members 32 and which rotate in contact with the suture 20 to push the suture 20 from the tube-type needle 10

The upper support roller 321 is rotatably combined with the supporting part 312, and the lower support roller 321 is rotatably combined with the supporting plate 313. The lower support roller 321 is combined with the supporting plate 313 which pivots flexibly with respect to the supporting part 312 and thus is elastically biased toward the upper support roller 321.

In the tube-type needle package according to the present embodiment, the suture 20 is inserted into the slot 311a to be combined with the body part 31. In this state, as shown in FIG. 6, the supporting plate 313 pivots so that the lower support roller 321 faces the upper support roller 321 and the suture 20 is disposed between the support rollers 321. After that, the other end 10b of the tube-type needle 10 is combined with the body part 31. Also, as shown in FIG. 7, the upper support roller 321 rotates to push the suture 20 into the tube-type needle 10. Here, the suture 20 is easily pushed by surface friction between the support rollers 321. In the present embodiment, the upper support roller 321 is rotated with the fingers. However, the present invention is not limited thereto and the upper support roller 321 may be rotated by various types of driving means, e.g., a motor, etc.

In the present embodiment, the suture 20 moves upwards using the support rollers 321. However, the present invention is not limited thereto, and the suture 20 may move upwards using a sliding means 323, as shown in FIGS. 8 and 9. For example, a tube-type needle package according to another exemplary embodiment includes a needle 10, a suture 20, and a handpiece 30. The handpiece 30 includes a body part 31 and a pushing member 32. A shape of the body part 31 according to the present embodiment is similar that of the body part 31 shown in FIGS. 6 and 7. The pushing member 32 includes a sliding surface 322 and the sliding means 323. The sliding surface 322 extends in a longitudinal direction of the suture 20 and the suture 20 can be safely placed thereon. The sliding means 323 is opposite to the sliding surface 322 so that the suture 20 is located between the sliding surface 322 and the sliding means 323. The sliding means 323 is combined with the body part 31 to move in the longitudinal direction of the suture 20 and moves in contact with the suture 20 put on the sliding surface 322 to push the suture 20 from the needle 10.

Here, the sliding means 323 is combined with the body part 31 to slide in the body part 31 through an elastic string 324 installed in the body part 31 so as to be elastically biased toward the sliding surface 322. Uneven surfaces may be formed on a surface of the sliding means 323 that contacts the suture 20. Thus, the suture 20 may easily move along the sliding means 323.

In the tube-type needle package shown in FIG. 8, when the sliding means 323, which is slightly spaced apart from the suture 20 put on the sliding surface 322, is pressurized, the sliding means 323 contacts the suture 20. Here, as shown in FIG. 9, when the sliding means 323 moves forward, the suture 20 moves forward with the sliding means 323. In the tube-type needle package described with reference to FIG. 6, the supporting plate 313 is pivotably combined with the supporting part 312 to be elastically supported by the elastic spring 314. However, in the present embodiment, the supporting plate 313 is combined with the supporting part 312 by a latch 312a. The sliding surface 322 indicates an upper surface of the supporting plate 313.

As shown in FIG. 10, an end 10a of a tube-type needle 10 may have a blunt cross-sectional shape to reduce friction occurring on a contact surface between the tube-type needle 10 and the suture 20 when the suture 20 is pushed from the tube-type needle 10.

The tube-type needle package of the present embodiment may be modified as shown in FIGS. 11 through 15.

FIG. 11 is a perspective view of a tube-type needle package 30 according to an exemplary embodiment of the present invention. FIG. 12 is a cross-sectional view of the tube-type needle package 30 of FIG. 11. FIGS. 13 and 14 are views illustrating major parts of the tube-type needle package 30 of FIG. 11, and FIG. 15 is a view illustrating an operation of the tube-type needle package 30 of FIG. 11. The tube-type needle package 30 includes a body part 33 and a pushing member 34. The body part 33 includes a body 331 in which a guide slot 331a is formed and extends in one direction and a bar member 332 which is pivotabley installed on the body 331.

The pushing member 34 includes a sliding part 341, a grabbing part 341a, an entering part 342, a guide part 343, a driven roller 347 (도면에 참조번호가 없습니다. 확인바랍니다), and pushing rollers 345 and 346 (도면에 참조번호가 없습니다. 확인바랍니다). The slide part 341 is installed in the guide slot 331a to slide in the guide slot 331a, and the grabbing part 341a is installed on the sliding part 341 so that a hand of a user grabs the grabbing part 341a. The entering part 342 is connected to the sliding part 341 and has a shape corresponding to an end part of a tube-type needle to be inserted into the end part of the tube-type needle. The guide part 343 is combined with the entering part 342 to guide a suture, and the driven roller 347 rotates in contact with the sliding part 341. The pushing rollers 345 and 346 receive a rotation force of the driven roller 347 to rotate, and the suture is inserted between the pushing rollers 345 and 346.

The driving roller 347 is rotatably combined with the body 331, the pushing roller 345 is rotatably combined with the body 331, and the pushing roller 346 is rotatably combined with the bar member 332.

A unidirectional gear is installed at the pushing roller 345 and receives the rotation force of the driven roller 347 to rotate the pushing roller 345 only if the driven roller 347 rotates in one direction. Therefore, if the driven roller 347 rotates in another direction, the pushing roller 345 ticks over. In more detail, the unidirectional gear includes projections 345a which are installed on the pushing roller 345 in a circumferential direction and hanging gears 345b which are hung on the projections 345a in one direction.

In a tube-type needle package according to an embodiment, if a sliding part moves, a driven roller combined with the sliding part rotates to rotate pushing rollers. Therefore, a suture contacting the pushing rollers is pushed to be moved. Also, an entering part combined with a needle moves forward to push the needle. If the sliding part moves backwards, the driven roller rotates, but the pushing rollers do not rotate with the driven roller due to a unidirectional gear and thus tick over separately from the driven roller. The entering part moves backwards with the needle.

A tube-type needle package according to the present invention may be used as follows. A needle into which a suture has been inserted is inserted into a living skin and then gets out of the living skin when an end part of the suture is fixed to a desired part of the living skin so that the suture is taken out from the needle to adhere to the living skin. When the needle is re-pushed, a pushing member operates to push the suture from the needle so as to adhere the suture to the desired part in zigzags. In other words, when the needle moves backwards, the suture naturally gets out of the needle. Thus, the pushing member does not need to be additionally used. However, when the needle moves forward to push the suture, the suture contacts an end part of the needle and thus does not easily get out of the needle. Here, the pushing member is used to easily push the suture from the needle.

In the above-described embodiments, a tube-type needle package may be used to perform an operation on an animal or the like but is not limited thereto. The tube-type needle package may be used on humans, i.e., may be used to perform various types of operations for removing wrinkles.

In a fixing method of a living tissue according to the present invention, a needle into which a suture has been inserted is fixed to a desired fixing part in zigzags, thereby providing a firm fixing force.

Also, since a desired part is elastically fixed in a state in which an incised part is minimized, an internal graft material is safely protected, and external germs are prevented from penetrating into living skin.

In a tube-type needle package according to the present invention, a handpiece is disposed to easily push a suture inserted into a needle to the outside. Therefore, an operation is further easily performed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
