[0034] like Figure 1 and Figure 6 As shown, it is a schematic diagram of a handle 1 or a structure including a handle 1, which is used to hold a surgical operating device. Its outer contour is designed according to ergonomic principles and presents a curve that matches the hand. There is a protrusion on the lower side of the middle end of the handle 1 to facilitate finger grip during surgery.

[0035] The handle 1 has a hollow structure inside, which extends along the axial direction of the handle 1 and extends from the front end to the rear end of the handle 1. The rear end of the handle 1 is a trumpet-shaped central hole that expands outward. The trumpet-shaped central hole is connected to the hollow structure in the handle 1, and the hole diameter is larger than the hole diameter of the hollow structure.

[0036] In addition, if Figure 2 As shown, the front end portion of the handle 1 is evenly divided into 10 grooves 11, and the curved catheter 3 can be matched with the handle 1 by rotating the position to be suitable for suturing a specific position of the meniscus area.

[0037] It should be noted that the front end portion of the handle 1 in this embodiment is not limited to having 10 grooves 11 , and may be less than 10 or more than 10.

[0038] like Figure 2 , Figure 4-7 As shown, it is a schematic diagram of a trigger component 2 or a structure including a trigger component 2. The trigger component 2 is installed on the handle 1. Specifically, a mounting hole 12 is provided on the handle 1. The mounting hole 12 is recessed inward from the outer wall of the handle 1 and is connected to the hollow structure of the handle 1. The mounting hole 12 is used to install the trigger component 2.

[0039] It is used to control the movement of the needle and suture within the hollow structure.

[0040] The details include a trigger 21, a trigger member 22, a first elastic member, a limiting shaft 24 and a second elastic member.

[0041] like Figure 4 and Figure 5 As shown, the trigger member 22 is a hollow cylinder with an axial opening, where the axial opening extends from one end of the hollow cylinder to the opposite end, or from one end of the hollow cylinder to the middle. The utility model does not limit the length of the axial opening. A first stepped hole 26 is provided on the end face of the front end of the trigger member 22. The first stepped hole 26 is arranged along the axial direction of the trigger member 22. The limit shaft 24 is installed in the first stepped hole 26. A shoulder 241 is provided at one end of the limit shaft 24 to limit the axial movement of the limit shaft 24. The second elastic member is placed on the outer side of the limit shaft 24 and contacts the end face of the trigger member 22. The second elastic member of this embodiment is preferably a second spring 25. The second spring 25 is sleeved on the limit shaft 24, and one end of the second spring 25 abuts against the end face of the trigger member 22.

[0042] like Figure 4 and Figure 5 As shown, the trigger 21 is installed in the opening of the trigger member 22 and is rotatably connected to the trigger member 22 , and a channel is defined between the bottom of the trigger 21 and the bottom inner wall of the trigger member 22 .

[0043] Specifically, Figure 5 As shown, the trigger 21 is provided with a first limiting hole 211 and a second limiting hole 212 , the first limiting hole 211 and the second limiting hole 212 are spaced apart by a preset distance, and the first limiting hole 211 and the second limiting hole 212 are both rotatably connected to the trigger member 22 via a pin shaft.

[0044] The first limiting hole 211 of the present embodiment is located at the end of the trigger 21 and is a circular hole. The pin shaft enables the trigger 21 and the trigger member 22 to be rotationally connected through the circular hole, specifically, the trigger 21 is rotated relative to the trigger member 22. The second limiting hole 212 is located in the middle of the trigger 21 and is spaced a certain distance from the first limiting hole 211. The second limiting hole 212 is preferably a strip hole, which is vertically arranged. The existence of the second limiting hole 212 can limit the movement range of the trigger 21, even if the trigger 21 rotates within a certain angle range relative to the limiting member.

[0046] The channel of this embodiment is preferably an arc-shaped channel 27, and the surface of the arc-shaped channel 27 is provided with a protrusion. The surface of the arc-shaped channel 27 here refers to the lower surface of the trigger 21, and the bottom surface of the hollow structure of the trigger member 22 opposite to the lower surface of the trigger 21. The lower surface of the trigger 21 and the bottom surface of the hollow structure of the trigger member 22 both have protrusions, which can be convex points or patterns. When the trigger 21 is pressed downward, the arc-shaped channel 27 and the inner surface of the trigger member 22 will squeeze the needle suture. As long as friction can be generated between the needle suture and the needle suture, the utility model does not limit the specific form of the protrusion.

[0047] In order to enable the trigger 21 to automatically rebound after being pressed, the trigger assembly 2 of this embodiment also includes a first elastic member, which is preferably a first spring 23. The first spring 23 is located below the trigger 21 and at the opposite end of the first limiting hole 211, that is, the first limiting hole 211 is located at one end of the trigger 21, and the first spring 23 is located below the opposite end of the trigger 21. An accommodating hole is provided on the trigger member 22, and the accommodating hole is used to accommodate the first spring 23.

[0048] like Figure 3 As shown, it is a schematic diagram of the structure of the curved catheter 3. A conical structure 31 is provided near the end of the curved catheter 3. The conical structure 31 can be integrally formed with the catheter body, or can be fixedly connected to the catheter body. This embodiment is not limited to this. The large radius end face of the conical structure 31 has two square protrusions, and the protrusions cooperate with the handle 1 through the grooves 11 at the front end of the handle 1, so that the protrusions on the conical structure 31 are adapted to the different grooves 11 of the handle 1, and can adapt to damaged soft tissues at different angles.

[0049] In this embodiment, the curved catheter 3 is connected to the handle 1 through a snap connection between the protrusion on the conical structure 31 and the groove 11 on the handle 1, so as to achieve a detachable connection between the handle 1 and the curved catheter 3. The curved catheter 3 also has a hollow structure arranged along the axial direction. The hollow structure of the curved catheter 3 in this embodiment is interconnected with the hollow structure inside the handle 1.

[0050] In order to facilitate the replacement of the curved catheter 3 and enhance the connection strength between the curved catheter 3 and the handle 1, as shown in FIG. Figure 6-8 As shown, the device of this embodiment further includes a replacement component 4 , which is installed at one end of the handle 1 close to the curved catheter 3 and is used to replace different curved catheters 3 .

[0051] Specifically, Figure 8As shown, the replacement assembly 4 includes a pressing member 41 and a third elastic member, the third elastic member is preferably a third spring 42, the bottom end of the pressing member 41 is provided with a second stepped hole 412, the third spring 42 is placed in the second stepped hole 412, specifically, the third spring 42 is placed in the second stepped hole 412, and the end abuts against the annular groove at the end of the curved catheter 3.

[0052] The side surface of the pressing member 41 of the present embodiment preferably has two positioning columns, and the positioning columns are preferably square columns 411 for realizing the positioning of the pressing member 41 .

[0053] The surgical operation device of this embodiment selects a suitable curved catheter 3 according to the location of the meniscus injury under the endoscope, and selects the rotation angle of the curved catheter 3 according to the location of the injury. The curved catheter 3 is connected to the handle 1, the first needle suture is passed through the end of the handle 1, the trigger 21 is pressed so that the bottom of the trigger 21 and the needle suture are squeezed, and the trigger 21 is continued to be pressed to move the needle suture forward until it is withdrawn from the rear of the meniscus incision. The device is moved to the next position, and the other end of the needle suture is withdrawn from the rear of the meniscus incision in the above manner, and the meniscus is repaired by tying the suture on the joint capsule. The device can realize the functions of tissue threading and manipulation suturing, and is easy to operate, does not need to replace multiple tools, and can be operated with one hand.

[0054] The surgical operation device for repairing damaged soft tissue in this embodiment is generally used in orthopedic surgery to repair muscle injuries, such as muscle injuries sustained during sports activities, knee meniscus repair, etc. In the case of a meniscus tear, it can be repaired by deploying needle sutures at both ends of the tear position, stretching the guide needles at both ends of the suture to suture the tear and guide the wound to heal. The needle suture does not have difficulty in pushing out during the operation, and the device structure conforms to the principle of ergonomics, can be operated with one hand, and the operation process is simple. The operating physician can use it after simple training.
