Description

Pushbutton installation structure of surgical instrument for repairing cartilage rupture

The present invention relates to a push button installation structure of a surgical tool for cartilage rupture recovery, and more particularly, a push button specially manufactured in a button joint hole formed on the tool body of a surgical tool for cartilage rupture recovery is combined to move up and down. The first fixing piece and the first fixing piece connected to the suture through the needle at the tip of the pusher guide and the first fixing piece installed in connection with the suture through the needle at the tip of the pusher guide while selectively advancing the pusher to a predetermined width in multi-steps through the motion of lowering or releasing the pushbutton. 2 By using a very simple method of discharging the fixing pieces sequentially, the first and second fixing pieces can be easily and safely fixed to the ruptured cartilage area.

It relates to a push button installation structure of a surgical tool for cartilage breakage repair that can facilitate repair of cartilage by stitching and suturing the area of cartilage fractured with sutures based on the later fixed first and second fasteners.

The introduction and development of minimal invasive surgery or robot surgery in the orthopedic field for rapid healing of patients is an inevitable reality in the medical field.

In the field of orthopedic surgery, ligament damage or muscle rupture due to sports injuries, arthritis or degenerative diseases is now the current trend and will continue in this direction in the future.

Therefore, an anchor (suture anchor) is used to attach damaged joint membranes, cartilage, muscles, and ligaments.

The surgical procedure involves mini-incision or arthroscopy of the lesion, and then the muscle or ligament of the lesion is fixed with a suture (e.g., fiberwire suture), and the lesion is exposed and a thread is attached thereto. Insert screws (anchors).

Sutures are attached to the anchor so that the detached ligaments or muscles can be stitched and attached to the bone. At this time, the anchor should be inserted through the cannular.

Pull the fallen or broken ligaments with sutures attached to the anchor, attach them to the bones, and make a knot.

Since this knot must be done outside the endoscope, it takes a considerable amount of time and if the correct knot is not made, the thread will loosen or loosen, preventing the muscle or ligament from attaching to the bone.

Mechanisms and systems related to the anchor insertion device are disclosed, for example, in Korean Patent No. 10-2012-123517, 10-2014-72657, 10-2014-116211, 10-2015-7028488, etc. have.

However, all of the mechanisms and systems related to the above-described anchor insertion device insert and fix an anchor with a suture connected into the bone, and then stitch the ligaments or muscles separated by the suture based on the anchor inserted into the bone and attach it to the bone. It is only used for surgery, for example, when cartilage in the knee area is ruptured and only this cartilage area is repaired by suturing it, it is virtually impossible to use.

The present invention was conceived in consideration of the above problems,

Provides surgical tools for cartilage rupture recovery, but by combining and installing a specially made push button in the button joint hole formed on the tool body of this surgical tool for cartilage rupture recovery so as to move up and down,

The first and second fixing pieces connected with the suture through the needle at the tip of the pusher guide are selectively moved forward by a predetermined width in multiple stages through the operation of lowering by pressing the push button or lifting by releasing the push button. By using a very simple method of discharging sequentially, the first and second fixing pieces can be easily and safely fixed only to the ruptured cartilage area.

The purpose is to facilitate the repair of the cartilage by sewing and suturing the ruptured cartilage part with sutures based on the first and second fixation pieces fixed to the ruptured cartilage, not the bone.

The push button installation structure of the surgical tool for cartilage rupture recovery of the present invention for achieving the object described in the problem to be solved is basically a spring in the button coupling hole of the tool body 100 constituting the surgical tool for cartilage rupture recovery. It is inserted and supported to receive the elastic repulsive force,

It is combined and installed so that it is connected to the pusher, and selectively advances the pusher in multiple stages when ascending or descending.

It is installed so that the first fixing piece and the second fixing piece installed in connection with the suture can be sequentially discharged through the needle at the tip of the pusher guide.

The push button has a lower body and an upper body fixed integrally, and a first stopper and a third stopper protruding upward before and after are formed on the lower body,

The upper body has a second stopper protruding downward so as to be positioned between the first stopper and the third stopper,

Initially, the protrusion of the push rod is caught by the first stopper and the advance is regulated.

When the push button is pressed, as the first stopper and the second stopper descend at the same time, the locking protrusion of the pusher leaves the first stopper and advances only to the second stopper. When the push button is released, the second stopper and the third stopper rise at the same time. Accordingly, the first fixing piece is discharged through the needle at the tip of the pusher guide as the locking protrusion of the pusher moves out of the second stopper and advances to the third stopper.

When the push button that has been raised is pressed again, as the third stopper descends again, the locking protrusion of the pusher leaves the third stopper and advances by the compressive elastic force of the spring, and the stepped or locking protrusion formed on the pusher is a wall surface or a tool in the gauge tube body. It can be made so that the second fixing piece is discharged through the needle at the tip of the pusher guide while being hung on the wall of the body and advancing only by a predetermined distance.

In addition, the present invention may be made by further configuring a safety pin that regulates the pressing operation of the push button.

The push button installation structure of the surgical tool for cartilage rupture recovery of the present invention is coupled to a button joint formed on the body of the tool body for cartilage rupture recovery so that a specially made push button is mounted up and down. The first and second fixing pieces connected with the suture are sequentially discharged through the needle at the tip of the pusher guide while selectively advancing the push rod to a predetermined width by lowering or releasing the push and raising and lowering. Giving has the advantage of being able to conveniently and safely install the first fixation piece and the second fixation piece on the ruptured cartilage through a very simple method.

Accordingly, the repair of cartilage can be made very easy by stitching and suturing the ruptured cartilage portion with a suture based on the first and second fixed pieces that are fixed later.

Moreover, since the push operation of the push button is controlled using a safety pin connected to the push button, the ejection operation of the first fixing piece and the second fixing piece is clearly distinguished. Malfunction of discharging the second fixing piece to a location other than the repositioning can be completely prevented.

Therefore, if the surgical tool for cartilage breakage repair to which the push button installation structure of the surgical tool for cartilage breakage repair of the present invention is applied is used, it is possible to safely and conveniently suture the broken cartilage.

In addition, the accompanying drawings are not drawn to scale to aid understanding of the invention, but dimensions of some components may be exaggerated.

First, the surgical tool for cartilage restoration on which the push button of the present invention is installed is largely coupled to the tool body 100 of a hollow body having a handle part on the rear outer surface, and the first fixing piece 501 and the first fixing piece 501 respectively. 2 Push button 200 used to press the fixing piece 502 forward, and a push button that sequentially discharges the first fixing piece 501 and the second fixing piece 502 by advancing the pusher 200 in multiple stages It comprises a gauge tube body 400 having a pusher guide 410 that guides the pusher 200 and is provided with a needle 411 having an incision 411a formed at the tip end thereof.

Here, the needle 411 is shown to be formed in a straight line for convenience in the embodiment, but may be formed in a curved line.

It will be described in more detail with respect to the surgical tool for cartilage recovery as described above and the push button installation structure of the present invention installed thereon.

First, a detailed description of the surgical tool for cartilage recovery, a tube body coupling hole 110 is formed on the front surface of the tool body 100 made of a hollow body constituting the surgical tool for cartilage recovery, and a button coupling hole 120 is formed on the front upper surface. ) Is formed, and a handle portion 130 is formed on the rear outer surface of the button coupling hole 120,

The gauge tube body 400 is coupled to the tube body coupling hole 110 formed on the front surface of the tool body 100 made of the hollow body,

The gauge tube body 400 surrounds the outer surface of the tip of the push rod 200, and a needle 411 that is sharp at the tip is provided, and an incision 411a is formed on the upper surface of the needle 411 to form a first fixing piece 501 ) And the rear end of the pusher guide 410 into which the second fixing piece 502 is inserted and installed, and the rear end of the gauge tube 421 surrounding the outer surface of the pusher guide 410 is coupled,

The gauge tube 421 has a rear end coupled to the gauge tube holder 420, and the gauge tube holder 420 is coupled to the gauge tube body 400 so as to be selectively forward and backward, so that the gauge tube holder 420 ) By moving the gauge tube 421 forward and backward at the same time to adjust the thickness of the ruptured cartilage, that is, the discharge length of the first fixing piece 501 and the second fixing piece 502 according to the conditions of the treatment site. I can.

On the other hand, in the tool body 100, a push rod 200 is installed. The rear end of the push rod 200 is inserted and installed to receive the elastic repulsive force of the spring 210, and the front end of the push rod 200 is a tube body coupling hole. It is inserted and installed so as to protrude long forward through the inside of the pusher guide 410 formed on the gauge tube body 400 coupled to the 110.

This time, the push button installation structure of the present invention connected to the surgical tool for cartilage recovery will be described in detail.

The push button 300 of the present invention is installed in the button coupling hole 120 of the tool body 100 constituting the surgical tool for cartilage recovery, and is coupled to be installed in connection with the pusher 200,

The push button 300 is, for example, divided into a lower button body 300a and an upper button body 300b, and is integrally assembled using an adhesive, and a spring 310 is installed on the bottom surface.

And the lower button body (300a) is formed with a first stopper (320) and a third stopper (340) protruding upward before and after.

A second stopper 330 protruding downward so as to be positioned between the first stopper 320 and the third stopper 340 is formed on the upper button body 300b.

Therefore, according to the above configuration, initially, the locking protrusion 200a of the push rod 200 is caught by the first stopper 320 and the advance is regulated.

When the push button 300 is pressed, the first stopper 320 and the second stopper 330 descend at the same time, so that the locking protrusion 200a of the push rod 200 leaves the first stopper 320 and the second stopper 330 The second stopper 330 and the third stopper 340 rise at the same time when the push button 300 is released after advancing only up to, so that the locking protrusion 200a of the pusher 200 pushes the second stopper 330. It goes out and advances to the third stopper 340.

Then, the first fixing piece 501 is discharged through the needle 411 at the tip of the pusher guide 410 by the pusher 200 that advances to the third stopper 340.

After the first fixing piece 501 is discharged through the method of pressing and raising the push button 300 in this way, when the push button 300 is pressed again, the third stopper 340 descends again. The locking protrusion 200a of the pusher 200 moves forward by the elastic repulsive force of the spring 210, leaving the third stopper 340, and the stepped 201 or the stopping protrusion 202 formed on the pusher 200 is formed on the gauge tube body. Each of the inner wall surface 401 in the 400 or the wall surface 101 in the tool body 100 advances only by a predetermined distance, and the second fixing piece 502 is moved forward by the pusher 200 that advances in this way. ) It is discharged through the needle 411 at the tip.

Here, the present invention may be achieved by further configuring a safety pin 600 that regulates the pressing operation of the push button 300.

The safety pin 600 is inserted into the push button 300 so that the front end receives the elastic repulsion of the spring 610, and the rear end is further protruded to the outside of the button coupling hole 120 and is locked by the safety pin 600 and pressed. It is configured so that the button 300 cannot be pressed.

In such a state, if the safety pin 600 is fully inserted into the push button, the locking protrusions 601 formed on both sides of the safety pin 600 move forward and are caught and fixed by the locking protrusions 301 formed on both inner sides of the push button 300. As a result, the lock is released so that the push button 300 can be pressed.

On the other hand, a safety pin release piece 121 is vertically installed inside the button coupling hole 120 of the tool body 100, and the locking protrusion 601 is coupled to the locking protrusion 301 of the push button 300 to be fixed. The locking protrusion 601 of the safety pin 600 that has been descending while being removed from the locking jaw 301 by the safety pin release piece 121 is pushed back by the elastic force of the compressed spring 610 while the safety pin 600 ) Is configured to release the fixation.

Hereinafter, the operating state of the surgical tool for cartilage repair according to the operation of the push button of the present invention having the above installation structure will be described in more detail.

4 shows that the rear end of the safety pin 600, in which the front end is inserted into the push button 300, is further protruded to the outside of the button coupling hole 120, and as a result, is locked by the safety pin 600, thereby pressing the push button 300. It represents an initial state that cannot be pressed.

In such a state, as shown in FIG. 5, when the safety pin 600 is fully inserted into the push button 300 during surgery, the locking protrusions 601 formed on both sides of the safety pin 600 move forward and then on both sides of the push button 300. The locking is released so that the push button 300 can be pressed by being caught and fixed by the formed locking projection 301.

At this time, the spring 610 provided on the safety pin 600 is compressed.

Then, when the first stopper 320 is lowered by pressing the push button 300 as shown in 6c, the locking protrusion 200a of the pusher 200, which was caught by the first stopper 320 as shown in FIG. Is moved away from the first stopper 320 by the compressive elastic force of the spring 210 and is caught by the second stopper 330 inside the push button 300 and advances only a predetermined distance.

At this time, since the bottom surface of the push button 300 is elastically supported by the spring 310, the spring 310 is compressed.

At the same time, as shown in Fig. 6c, since the safety pin release piece 121 is vertically installed inside the button coupling hole 120 of the tool body 100, the locking protrusion 601 on the locking protrusion 301 of the push button 300 The locking protrusion 601 of the safety pin 600, which was lowered while being fixed and coupled, escapes from the locking jaw 301 by the safety pin release piece 121, and is backwards by the elastic force of the spring 210 that was compressed at the same time. While being pushed, the fixing of the safety pin 600 is released.

In such a state, when the push button 300 is released as shown in FIG. 7A, the push button 300 and the second stopper 330 inside the push button 300 are simultaneously raised by the elastic force of the spring 310. do.

Then, as shown in FIG. 7, the locking protrusion 200a of the pusher 200, whose control is released due to the rise of the second stopper 330, advances to the third stopper 340.

In this way, the first fixing piece 501 is discharged through the needle 411 at the tip of the pusher guide 410 by the pusher 200 that advances to the third stopper 340 as shown in FIG. 7C.

At this time, the discharged first fixing piece 501 passes through one side of the ruptured cartilage and is located on the back side.

In addition, as shown in Fig. 7d, the safety pin 600, which is released from the fixing in the push button 300, which has been lifted by the elastic force of the spring 310, is returned to the initial state by the elastic force of the spring 610, and the push button 300 ) Becomes locked again.

That is, in this state, as already described in FIG. 4, the rear end of the safety pin 600 having the front end inserted into the push button 300 protrudes further to the outside of the button coupling hole 120, and as a result, the safety pin 600 It is locked by the push button 300 is to be in an initial state that cannot be pressed.

As described above, FIGS. 4 to 7D show a method of discharging the first fixing piece 501, and this time, a method of discharging the second fixing piece 502 will be described.

In order to discharge the second fixing piece 502, the safety pin 600 must be reinserted into the push button 300 as shown in FIG. 8 and released by locking.

That is, as shown in Fig. 7d, in order to get out of the state in which the push button 300 cannot be pressed because it is locked by the safety pin 600, the locking is released by inserting and fixing all of the safety pin 600 into the inside of the push button 300. The push button 300 is converted to a state in which it can be pressed.

When all the safety pins 600 are inserted into the push button 300 as described above, the locking projections 601 formed on both sides of the safety pin 600 advance as described above, and then locking projections formed on both inner sides of the push button 300 ( Locking is released so that the push button 300 can be pressed by being caught and fixed by the 301

At this time, the spring 610 provided on the safety pin 600 is compressed.

Then, as shown in FIG. 9, the push button 300 is pressed and lowered.

Then, as the push button 300 is pressed, as shown in FIG. 10A, the third stopper 340 inside the push button 300 descends, and the push button 200, which was caught by the third stopper 340, was regulated. The locking protrusion 200a moves forward from the third stopper 340 by the compressive elastic force of the spring 210, and the step 201 or the locking protrusion 202 formed on the pusher 200 is the gauge tube body 400 Each of the inner wall surface (4-1) or the tool body (100) is hung on the wall surface (101) and advances only a predetermined distance, and the second fixing piece (502) is pushed forward as shown in FIG. 10B by the pusher (200) advancing in this way. It is discharged through the needle 411 at the tip of the guide 410.

At this time, the discharged second fixing piece 502 passes through the other side and is located on the back side in order to suture the ruptured cartilage.

Here, the spring 310 supporting the bottom surface of the push button 300 is compressed as the push button 300 descends.

In addition, at the same time, as shown in FIG. 10C, the safety pin release piece 121 is vertically installed inside the button coupling hole 120 of the tool body 100, so that the locking protrusion 301 of the push button 300 ( The locking protrusion 601 of the safety pin 600 descending while the 601 is coupled and fixed is released from the locking jaw 301 by the safety pin release piece 121 and at the same time is applied to the elastic force of the spring 610 compressed. The safety pin 600 is released while being pushed back.

When the push button 300 is released in such a state, the push button 300 is raised by the compression elastic force of the spring 310 compressed on the bottom of the push button 300 as shown in FIG. 11A,

As shown in FIG. 11B, when the rise of the push button 300 is completed, the safety pin 600, which is released from the fixing in the push button 300, returns to the initial state by the elastic force of the spring 610, and the push button 300 is again It is in a locked state.

After performing the above-described method, the first fixing piece 501 and the second fixing piece 502 are simply, quickly, and, above all, securely and completely fixed on the back side of the connection rupture to be sealed. After removing the surgical tool for cartilage rupture recovery, general post-procedures such as stitching and suturing the ruptured cartilage using a suture 10 based on the first fixation piece 501 and the second fixation piece 502 are performed. Just do it.

As described above, if the surgical tool for cartilage rupture recovery to which the push button of the present invention is applied is used, it is possible to repair the ruptured cartilage by suturing it very simply and safely.

In addition, in the present invention, the first fixing piece 501 and the second fixing piece 502 are discharged by intercepting the pressing operation of the push button 300 using the safety pin 600 connected to the push button 300. Since it is clearly distinguished, the push button 300 is pressed until the operator inserts the safety pin 600 into the push button after discharging the first fixing piece 501 to release the locking of the push button 300 again. Because it does not lose, it is possible to completely prevent a malfunction of accidentally discharging the second fixing piece 502 to a location other than the original location.
