Description

Wire gripping module for surgery {WIRE GRIPPING MODULE FOR SURGERY}

The present invention relates to a wire gripping module for surgical procedures.

Recently, the use of computers and smartphones has increased dramatically, and as more people enjoy various sports and hobbies such as golf and cooking, the occurrence of various diseases in the hands and wrists is also increasing. Among these, the most representative diseases are carpal tunnel syndrome and trigger finger.

Carpal tunnel syndrome occurs when the median nerve, which passes through the center of the empty space in the middle of the wrist (carpal tunnel, carpal tunnel), is compressed by the carpal tunnel ligament, causing long-term numbness and pain, or in severe cases, paralysis of the thumb, etc. Symptoms such as inability to move may occur.

Trigger finger is a disease in which nodules or swellings form in the flexor tendon of the finger or the A1 trochlea that holds the tendon becomes thicker, causing friction and pain every time the finger moves. In severe cases, it becomes very difficult to bend or straighten the finger. It may also be accompanied by arthritis of the finger joints.

If both diseases are mild, they can be treated non-surgically, but if they are severe, they cannot be treated non-surgically and can be treated surgically. Here, the surgical method is to cut the carpal tunnel ligament that compresses the median nerve at the wrist in the case of carpal tunnel syndrome, and to cut the A1 trochlea that compresses the flexor tendon in the case of trigger finger.

However, in the case of the traditional incision method during surgical treatment, the average period for normal activities after surgery is more than 2 months, which causes a lot of discomfort, so the non-incision method is preferred.

Regarding the non-incision surgical method that requires only a small incision for the treatment of carpal tunnel syndrome and trigger finger, the ligament thread crossing method and device in Korean Patent Publication No. 10-2015-0008067 has been disclosed. .

The prior art goes through the following process to arrange the cutting element so that it surrounds the carpal tunnel ligament or A1 trochlea in a U-shape.

1) The cannula needle enters the body through the anterior incision of the target tissue (carpal tunnel ligament or A1 trochlear), passes through one side (e.g., upper side) of the target tissue, and exits the body through the posterior incision of the target tissue.

2) Pass the cutting element inside the cannula, pass through one side (e.g., upper side) of the target tissue, bring one end of the cutting element outside the body, and then remove only the cannula.

3) Enter the cannula needle again into the body through the same anterior incision as in 1), and this time pass through the other side (e.g., lower side) of the target tissue and come out of the body through the same posterior incision of the target tissue as in 1).

4) Pass the end of the cutting element through the inside of the cannula from the posterior incision window, pass through the other side (e.g., lower side) of the target tissue, bring the end of the cutting element out to the outside of the body through the front incision window, and then remove only the cannula.

As such, the prior art had to form two incisions to cut the target tissue, which had the problem of increasing side effects, surgery time, and recovery time.

Figure 1 is a perspective view showing a wire gripping module for procedures according to an embodiment of the present invention, and Figure 2 is an exploded perspective view showing a wire gripping module for procedures according to an embodiment of the present invention.

As shown in Figures 1 and 2, the wire gripping module for surgery according to an embodiment of the present invention includes a cannula 100 and a gripper 200.

The cannula 100 serves to be inserted into the living body or discharged to the outside of the living body through a single incision in the living body.

For example, the cannula 100 is inserted into the living body through a single incision in the living body and serves to grip the surgical wire 10 that has entered one side of the target tissue through the single incision in the living body. Details will be explained in the operation example below.

Afterwards, the cannula 100 is discharged to the outside of the living body through a single incision in the living body, and the surgical wire 10 gripped by the cannula 100 is guided to the other side of the target tissue. Details about this are provided below. This will be explained in an operational example.

The surgical wire 10 serves to cut the target tissue of the living body. However, in order for the surgical wire 10 to cut the target tissue of a living body, a process of wrapping the target tissue of the living body in a U-shape is required, and details about this will be explained in the operation example below.

In one embodiment, the cannula 100 forms a channel 110 therein, and may have an insertion portion 120 through which a surgical wire 10 for cutting target tissue of a living body is inserted into the channel 110. there is.

In one embodiment, the channel 110 formed inside the cannula 100 may be formed along the longitudinal direction of the cannula 100. A gripper 200 may be provided to move reciprocally in this channel 110. Additionally, the cannula 100 may have a closed front end and an open rear end. Accordingly, the channel 110 may be formed through the rear end of the cannula 100 to the front end of the cannula 100.

In one embodiment, the insertion portion 120 formed in the cannula 100 may be formed to penetrate the outer periphery of the cannula 100 to communicate with the channel 110. The surgical wire 110 may be inserted into this insertion portion 120, and details about this will be explained in an operation example that will be described later.

The gripper 200 is provided to be reciprocatable in the channel 110 of the cannula 100, and grips the surgical wire 10 inserted into the channel 110 of the cannula 100 through the insertion portion 120. It plays a role.

In one embodiment, the gripper 200 may have an outer diameter that corresponds to the inner diameter of the channel 110 of the cannula 100. Therefore, when the gripper 200 enters the distal end of the cannula 100 via the insertion portion 120 of the cannula 100, the surgical wire 10 inserted into the insertion portion 120 of the cannula 100 ) may be gripped by the friction force generated between the inner diameter of the cannula 100 and the outer diameter of the gripper 200.

The wire bending guides 210 and 220 are formed to protrude in an area around the distal end of the gripper 200 and bend the surgical wire 10 inserted into the insertion portion 120 of the cannula 100. It can be guided to adhere closely to the inner circumference of . Specifically, when the gripper 200 enters the distal end of the cannula 100 via the insertion portion 120 of the cannula 100, the wire bending guides 210 and 220 are inserted into the insertion portion 120 of the cannula 100. ), the surgical wire 10 inserted into the cannula 100 is bent toward the inner periphery of the cannula 100, so that the surgical wire 10 can be brought into close contact with the inner periphery of the cannula 100.

The wire bending guides 210 and 220 have a first inclined portion 210 that protrudes obliquely from one side of the distal end of the gripper 200 and a direction opposite to the first inclined portion 210 from the other side of the distal end of the gripper 200. It may have a second inclined portion 220 that protrudes at an angle.

The surgical wire 10 may include at least one of stainless steel and silicone. In this case, since the surgical wire 10 may have rigidity, the direction of the surgical wire 10 inserted inside the living body can be adjusted by rotating the surgical wire 10 inserted inside the living body.

Hereinafter, an operation example of the wire gripping module for surgery according to an embodiment of the present invention will be described.

However, the operating example illustratively describes the cutting procedure of the carpal tunnel ligament among the target tissues of the living body, but the present invention is not particularly limited thereto, and it should be noted in advance that it can be applied to other tissues such as the A1 trochlear in addition to the carpal tunnel ligament.

Figures 3 to 7 are schematic diagrams showing the process of carpal tunnel ligament cutting using a surgical wire gripping module according to an embodiment of the present invention. The following amputation procedure can be performed by an operator or a slave robot.

As shown in FIG. 3, first, a single incision 20 is formed on one side (e.g., front) of the wrist adjacent to the carpal tunnel ligament 30, and the surgical wire 10 is injected through the single incision 20. ) is inserted, and the surgical wire 10 is introduced into one side (for example, the upper or lower side) of the carpal tunnel ligament 30. In this process, the single incision 20 may be formed by incision with a separate medical knife or needle. Additionally, the single incision window 20 is not particularly limited, but may have a diameter of 1 to 2 mm.

As shown in Figure 4, next, the cannula 100 is inserted through the single incision 20. Here, the cannula 100 may be entered into the other side (e.g., the lower side) of the carpal tunnel ligament 30, and at this time, the tip of the surgical wire 10 is inserted into the insertion portion 120 of the cannula 100. It can be. However, it may be difficult for the operator to check whether the surgical wire 10 is inserted into the insertion portion 120 of the cannula 100. Therefore, in this process, in order to check whether the surgical wire 10 is inserted into the insertion portion 120 of the cannula 100, an ultrasonic probe that takes an ultrasound image of the inside of the wrist or an ultrasonic probe at the end of the cannula 100 is used. An endoscope can be used to photograph the inside of the wrist.

As shown in Figure 5, the gripper 200 is then introduced into the distal end of the cannula 100. At this time, the surgical wire 10 inserted into the channel 110 of the cannula 100 through the insertion portion 120 of the cannula 100 causes a gap between the inner diameter of the cannula 100 and the outer diameter of the gripper 200. It is gripped by friction. At this time, in this process, it may be difficult for the operator to check whether the surgical wire 10 in the cannula 100 is gripped. Therefore, in this process, in order to check whether the surgical wire 10 is gripped in the cannula 100, an ultrasonic probe that takes an ultrasound image of the inside of the wrist or an ultrasound probe provided at the end of the cannula 100 to take an image of the inside of the wrist An endoscope may be used.

As shown in FIG. 6, the cannula 100 gripped with the surgical wire 10 is discharged to the outside of the wrist through the single incision 20. As a result, as the surgical wire 10 gripped by the cannula 100 is guided to the other side (e.g., the lower side) of the carpal tunnel ligament 30, the surgical wire 10 is connected to the carpal tunnel ligament 30. One side (for example, the upper side) and the other side (for example, the lower side) are wrapped in a U-shape.

Thereafter, the gripper 200 is moved to the rear end of the cannula 100 to release the gripping of the surgical wire 10 gripped on the cannula 100. As a result, both ends of the surgical wire 10 are exposed to the outside of the wrist through the single incision window 20.

As shown in Figure 7, finally, both ends of the surgical wire 10 exposed to the outside of the wrist through the single incision 20 are pulled. As a result, the carpal tunnel ligament 30 is cut by the traction of the surgical wire 10.

Therefore, when using the wire gripping module for surgery according to an embodiment of the present invention, an incision is not formed on the other side (e.g., the back) of the skin adjacent to the target tissue, but rather on one side (e.g., the back) of the skin adjacent to the target tissue. For example, a single incision window 20 is formed only in the front (front), the surgical wire 10 is placed on one side (e.g., the upper side) of the target tissue, and then the surgical wire gripping module of the present invention is used. If the distal end of the surgical wire 10 is held and passed through the other side (e.g., lower side) of the target tissue and the distal end of the surgical wire 10 is brought out of the body through the single incision window 20, a single incision window ( 20) alone, amputation surgery of the carpal tunnel ligament or A1 trochlea is possible.

According to the present invention, the surgical wire gripping module according to an embodiment of the present invention cuts the target tissue by forming only a fine single incision window 20 in the living body, even when cutting the carpal ligament 30 and the A1 trochlear. By cutting the carpal tunnel ligament 30 by forming only a single incision window 20, there is an effect of reducing side effects and shortening the surgery and recovery time.

Above, embodiments of the present invention have been described with reference to the attached drawings, but those skilled in the art will understand that the present invention can be implemented in other specific forms without changing its technical idea or essential features. You will be able to understand it. Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive.
