[0022] The technical solutions of the present utility model will be further elaborated in detail below in conjunction with the accompanying drawings of the specification and specific embodiments;

[0023] Embodiment 1:

[0024] A minimally invasive fascia suture device with a positioning and wire-grabbing anti-slip function provided by the present application includes a fascia suture device main body 1; two groups of connecting plates 5 are rotatably installed on the outer wall of the fascia suture device main body 1, a protection mechanism 8 is installed on the surface of the connecting plates 5, a wire groove 2 is provided on the outer wall of the fascia suture device main body 1, a fixing block 3 is installed inside the wire groove 2, two groups of suture threading devices 6 are cross-installed inside the fascia suture device main body 1, and a wire-grabbing mechanism 7 is installed at the bottom of the suture threading device 6;

[0025] The protection mechanism 8 includes a spring 801, a protection plate 802, and a protection pad 803. Springs 801 are installed on both sides of the surface of the connecting plate 5, a protection plate 802 is installed at the top of the spring 801, and a protection pad 803 is provided on the surface of the protection plate 802;

[0026] Specifically, as Figure 1 andFigure 4 As shown, the wire grasping mechanism 7 is used to grasp the suture line and prevent it from slipping off when grasping the suture line. By clamping the suture line into the wire groove 2 and clamping it into the fixing block 3 for fixation, then inserting the fascia stapler main body 1 into the surgical opening. The fixing block 3 can prevent the wire from sliding off. The wire is unfolded through the connecting plate 5 to form a triangle with the fascia stapler main body 1. At this time, the suture passer 6 is inserted into the fascia stapler main body 1. The wire grasping mechanism 7 is operated to grasp the wire, and then the patient is sutured. The protection mechanism 8 is used to protect the abdominal wall at the surgical opening of the patient. The protection pad 803 is made of flexible material. When the fascia stapler main body 1 moves to the surgical opening of the patient and moves the use position of the fascia stapler main body 1, the protection pad 803 can prevent the protection plate 802 from directly contacting the abdominal wall at the surgical opening of the patient. At the same time, the protection plate 802 will cause the spring 801 to deform, avoiding the doctor from moving the connecting plate 5 excessively and increasing the discomfort of the patient.

[0027] Furthermore, a pressure sensor 9 is installed at the inner top of the protection plate 802;

[0028] Specifically, as Figure 4 shown, in order to detect the moving position of the connecting plate 5, the fascia stapler main body 1 is moved to drive the connecting plate 5 to move, so that the expanded surface of the connecting plate 5 fits onto the patient's abdominal wall. The pressure sensor 9 can detect the pressure received by the connecting plate 5, and then play a role in prompting the doctor.

[0029] Furthermore, the wire grasping mechanism 7 includes a connecting rod 701, a clamping jaw 702 and a connecting spring 703. The connecting rod 701 is installed inside the suture passer 6. A connecting spring 703 is installed between the outer side of the connecting rod 701 and the suture passer 6. The clamping jaw 702 is installed at the bottom of the connecting rod 701;

[0030] Specifically, as Figure 2 and Figure 3 shown, in order to grasp the wire guided on the fascia stapler main body 1 and prevent the wire from falling off, resulting in the fascia stapler main body 1 being unable to suture the patient's peritoneum and fascia layer, the doctor presses the connecting rod 701, and the connecting spring 703 on the outer side of the connecting rod 701 will deform. Then the bottom end of the connecting rod 701 moves out from the bottom of the suture passer 6. At this time, the clamping jaw 702 opens to hook the wire. When the doctor releases the connecting rod 701 and does not apply pressure to the connecting rod 701, the connecting rod 701 will drive the clamping jaw 702 to reset under the action of the connecting spring 703, so as to grasp the wire guided on the fascia stapler main body 1, facilitating the doctor to operate the fascia stapler main body 1 to suture the patient's peritoneum and fascia layer.

[0031] Further, a locking tooth 4 is fixedly installed inside the fascia stapler body 1, and a push lock block 401 is slidably installed inside the fascia stapler body 1;

[0032] Specifically, as Figure 1 shown, in order to unfold the connecting plate 5 and enable the connecting plate 5 to lead the thread, insert the fascia stapler body 1 into the surgical opening, pull the push lock block 401, so that the connecting plate 5 is caught by the locking tooth 4. At this time, operate the pull rod on the fascia stapler body 1 to push forward, then the rack meshes with the tooth groove on the connecting plate 5, and drives the connecting plate 5 to rotate along the rotating shaft inside the groove 501. The connecting plate 5 is pulled open, and the suture forms a triangular state as the connecting plate 5 opens, so that the connecting plate 5 leads the thread.

[0033] Further, two groups of grooves 501 are provided on the outer wall of the fascia stapler body 1, and a connecting plate 5 is connected inside the grooves 501;

[0034] Specifically, as Figure 1 shown, in order to store the connecting plate 5 and prevent the connecting plate 5 from protruding to increase the occupied area of the device, the connecting plate 5 is rotatably connected inside the groove 501. By rotating the connecting plate 5, the connecting plate 5 will move into the groove 501 for storage, thereby reducing the occupied area of the device.

[0035] Working principle: Clamp the suture into the wire groove 2 and fix it in the fixing block 3. Then insert the fascia stapler body 1 into the surgical opening, pull the push lock block 401, so that the connecting plate 5 is caught by the locking tooth 4. At this time, operate the pull rod on the fascia stapler body 1 to push forward, then the rack meshes with the tooth groove on the connecting plate 5, and drives the connecting plate 5 to rotate along the rotating shaft inside the groove 501. The connecting plate 5 is pulled open, and the suture forms a triangular state as the connecting plate 5 opens. Move the fascia stapler body 1 appropriately so that the opening surface of the connecting plate 5 fits against the abdominal wall. Then insert the suture passer 6 into the fascia stapler body 1 and pass it out from one side of the connecting plate 5, and press the connecting rod 701. The bottom end of the connecting rod 701 moves from the bottom of the suture passer 6. At this time, the clamping jaws 702 open to hook the thread. When the connecting rod 701 is released, the connecting rod 701 will drive the clamping jaws 702 to reset under the action of the connecting spring 703, and the suture passer 6 successfully grabs the thread. Withdraw the suture passer 6 to bring out the suture. Repeat the above process on the other side to pull out the suture on the other side. Push open the push lock block 401 to release the engagement with the locking tooth 4, push the push lock block 401 to close the connecting plate 5, take out the suture in the wire groove 2 at the bottom of the fascia stapler body 1, tighten the sutures at both ends, and fix the two ends according to the suture knotting method to complete the suture.

[0036] Finally, it should be noted that the above specific implementation manners are only used to illustrate the technical solutions of the present utility model rather than to limit them. Although the present utility model has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified and equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
