Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a disposable minimally invasive surgical punch card opening closer and a closing method.
Background
In recent years, minimally invasive surgery has been rapidly developed and is widely used in the surgical field. Minimally invasive surgery has developed rapidly, largely replacing the routine surgical site, and is listed as a trend of preference for the standard protocol. Compared with the opening of the traditional operation, the opening of the minimally invasive operation adopting the poking card is very small. After the operation is finished, the suture is not easy to close. To effectively suture fascia in the inner cavity, prevent injury to viscera, avoid postoperative hernia, and is very difficult.
The prior art has the apparatus to realize fascia closure of the opening of the poking card, such as Chinese patent numbers 201510816559.6, 201621057873.7 and 201621459357.7, but has the following technical problems:
1. the apparatus described in Chinese patent No. 201510816559.6, the needle body of the puncture needle is provided with a reverse hook groove. If the slot width is too narrow, the suture is easy to be blocked on the needle body, so that after the puncture needle penetrates through the silica gel block, the suture is not clamped by the silica gel block and still blocked on the needle body when the needle body is pulled out; if the groove width is too wide, the needle body is weak, the strength of the puncture needle is insufficient, the force is not applied when the puncture needle is used for puncturing human tissues, and bending accidents are easy to occur at the needle groove; when the puncture needle passes through the silica gel block, the reverse hooking groove structure easily causes the silica gel block to be broken, so that scraps of the silica gel block fall into the abdominal cavity to remain in a human body, and the use safety is poor;
2. the instrument described in chinese patent No. 201621057873.7 uses a tiny grapple to grasp the suture inside the body. The grapple is not easy to operate and can not effectively grasp the suture; meanwhile, the grapple exceeds the boundary of the instrument, so that the risk of puncturing tissues in the body exists;
3. the device described in chinese patent No. 201621459357.7 releases the suture after the silicone block is penetrated with the sleeve structure. After the sleeve is pulled out, the wound left by the sleeve on the silica gel block is far larger than the diameter of the suture, so that the silica gel block can not effectively clamp the suture, and finally the suture falls off from the silica gel block under slight pulling force, and the suture can not be completed.
4. All of the above instruments must be operated in the visual field when performing the suturing procedure. When suturing the last access opening left to the endoscopic instrument providing the field of view, the last access opening cannot be sutured using such instrument because no field of view is available in the body after the endoscope is withdrawn.
Therefore, those skilled in the art have been working on developing a disposable minimally invasive surgical punch opening closer and closing method, which can improve the needle body structure of the puncture needle, increase the strength of the puncture needle, and avoid bending at the notch; the structure of the suture clip in the silica gel block is improved, the suture clamping force is enhanced, and the phenomenon that the suture is accidentally pulled out of the silica gel block is avoided; the method improves the mode that the puncture needle penetrates through the silica gel block, accurately positions the depth of the puncture needle, improves the operation accuracy, and realizes that suturing under the field of view of an endoscope is not needed.

step S1: passing the front end of the closure body through the dermal tissue through an opening left by the poking card, ensuring that the front end is fully within the body;
step S2: deploying the deployable mechanism such that the first proximal wing and the second proximal wing are proximate an inner wall of the skin tissue;
step S3: the thread anchor and the suture are kept in the trocar, the trocar is used for penetrating the skin tissue along the first needle guiding cavity and penetrating the first clamping block, and the depth of the trocar is accurately positioned through the relative positions of the scale marks and the first needle guiding cavity, so that the trocar is ensured to just penetrate the first clamping block;
step S4: pushing the wire anchor into the push rod channel by the push rod until the push rod reaches the limit device of the push rod, and enabling the wire anchor to slide out of the trocar with the suture and then reach the inner side of the human body of the first clamping block;
step S5: pulling out the push rod and the trocar;
step S6: pulling the suture slightly with force to enable the thread anchor to be clung to the inner side of the human body of the first clamping block;
step S7: repeating the steps S4-S6, and penetrating the second clamping block along the second needle guiding cavity by using the trocar, so that the wire anchor at the other end of the suture is tightly attached to the inner side of the human body of the second clamping block;
step S8: closing the first proximal wing and the second proximal wing;
step S9: pulling out the closure body, tightening the suture closes the opening left by the skin tissue.
2. The disposable minimally invasive surgical punch aperture closer of claim 1, wherein the centers of the first and second clamp blocks have a valve structure having an outer diameter greater than the maximum diameter of the wire anchor and a central aperture smaller than the maximum diameter of the wire anchor.
3. The disposable minimally invasive surgical punch aperture closer of claim 2 wherein the valve structure is funnel-shaped protruding toward the inside of the human body.
4. The disposable minimally invasive surgical punch aperture closer of claim 2, wherein the valve structure is planar.
5. The disposable minimally invasive surgical punch aperture closer of claim 2, wherein the first and second clamp blocks are sheet metal.
6. The disposable minimally invasive surgical punch aperture closer of claim 1 wherein the wire anchor comprises an anchor tip and an anchor tail, the anchor tip being a cone, the anchor tail being fixedly attached to the suture.
7. The disposable minimally invasive surgical punch aperture closer of claim 1 wherein the wire anchor comprises an anchor tip and an anchor tail, the tip of the anchor tip being a cone, the tail of the anchor tip being a wedge on either side of the anchor tail, the anchor tail being fixedly attached to the suture.
8. The disposable minimally invasive surgical punch aperture closer of claim 1 wherein the wire anchor comprises an anchor tip and an anchor tail, the tip of the anchor tip being a cone, the tail of the anchor tip being an outwardly directed pointed body on one side of the anchor tail, the anchor tail being fixedly attached to the suture.
