[0002] Laparoscopic surgery and thoraco-laparoscopic surgery are one of the main treatment methods of minimally invasive surgery. They have been widely used because of their small trauma and quick recovery. In abdominal examination, abdominal surgery and other minimally invasive or surgical operations, puncture devices are widely used. The puncture device can establish an entry channel in the abdominal wall of the human body to allow a laparoscope or other surgical instruments, such as laparoscopic operating instruments, guide wires, catheters, etc. to enter the abdominal cavity for corresponding examinations or surgical operations.
[0003] Existing puncture devices generally only have the function of establishing instrument surgical channels, and cannot simultaneously assist in the suturing of key abdominal wall tissues. When suturing a wound, the puncture device is usually pulled out and then the suturing device is inserted into the abdominal cavity for suturing. Due to the narrow puncture hole, even if the fascia and peritoneal tissues can be exposed, the suturing needle is difficult to rotate due to the small space during suturing, making suturing very difficult or even inaccurate.

[0006] A suture needle is arranged in the middle of the suture needle storage hole, top blocks are symmetrically fixedly connected to both sides of one end of the puncture core, a suture thread is arranged at one end of the suture needle, a barb is arranged at one end of the suture needle, and a limiting mesh plate is arranged in the middle of the reserved hole.
[0007] Preferably, the unfolded cross-sectional shape of the elastic band is set to be a triangle, and the end of the guide block away from the handheld end of the puncture cannula is elastically connected to the wall of the puncture cannula.
[0008] Preferably, the elastic band is arranged on a side of the reserved hole away from the handheld end of the puncture sleeve, and a side wall of the guide block away from the elastic band is arranged as an arc-shaped structure.
[0009] Preferably, the cross-sectional shape of the suture needle storage hole is set to be an arc, and the opening position of the suture needle storage hole corresponds to the reserved hole.
[0010] Preferably, the top block corresponds to the guide block, the elastic bands are arranged on both sides of the top block, and the cross-sectional shape of the top block is set to be a triangle.
[0011] Preferably, the needle head of the suture needle is located at the opening position of the suture needle storage hole, and the suture thread passes through the tail of the suture needle.
[0012] Preferably, one end of the suture thread extends into the interior of the puncture sleeve through the reserved hole.
[0013] Technical effects and advantages of the utility model:
[0014] 1. The utility model can store suture needles by means of the guide block and the suture needle storage hole, which is convenient for use when suturing is needed, and the guide block can be expanded by pushing the guide block by the top block, thereby stretching the elastic band, so that the opening of the suture needle storage hole corresponds to the reserved hole, so that after the suture needle extends from the inside of the suture needle storage hole, one end of the suture needle can be moved to the side close to the reserved hole, so that one end of the suture needle extends into the inside of the reserved hole, and drives the suture thread to move along the route of the suture needle, so as to achieve the suturing effect and facilitate suturing use;
[0015] 2. The utility model also allows one end of the suture needle to penetrate the reserved hole and extend into the interior of the puncture sleeve through the reserved hole, and the suture needle can be taken out by extending the clamp into the interior of the puncture sleeve, which is convenient for use. The elastic band can generate a pulling force on the guide block, so that the guide block fits the wall of the puncture sleeve in a normal state without affecting normal use. When the guide block is squeezed by the top block, the guide block is unfolded and tilted, which is convenient for suturing and improving the use effect. The barbs are inserted into the limiting mesh plate to prevent one end of the suture needle 7 from moving out from the interior of the puncture sleeve 1 when it extends into the interior of the puncture sleeve 1, thereby playing a limiting role.
[0016] In summary, through the mutual influence of the above-mentioned multiple effects, suturing can be performed when the wound needs to be sutured, and the moving path of the suture needle can be limited to improve the suturing effect. BRIEF DESCRIPTION OF THE DRAWINGS
