Description

Technical Field

[0001] The present invention relates to the technical field of staplers, and in particular to an abdominal wall stapler with a puncture function. Background Art

[0002] Staplers are widely used medical devices in surgical operations. Their core function is to accurately cut and suture human tissues, thereby significantly improving the efficiency and accuracy of surgical operations and effectively reducing the difficulty of surgery. In the field of abdominal surgery, abdominal wall staplers are mainly used to repair abdominal wall defects, reconstruct abdominal wall structures, or promote wound healing. They ensure surgical results by achieving accurate anastomosis of abdominal wall tissues.

[0003] However, the mainstream abdominal wall staplers on the market currently lack puncture functions. Before performing the anastomosis operation, medical staff must first use a puncture to establish a surgical channel. This additional surgical step not only increases the overall time and complexity of the operation, but may also lead to increased surgical risks and increased infection rates. At the same time, the additional surgical steps also increase the workload of medical staff and may have an adverse effect on the accuracy of the operation. Summary of the invention

The threaded sleeve can be threadedly connected to the puncture core to facilitate the end of the stapler body to pass through the ring body and then be inserted into the puncture core.

[0027] According to a refinement of the solution, the fastening bolt can be rotated to abut against the stapler body to limit the relative movement between the ring body and the stapler body.

[0028] The scheme is refined, the stapler body can slide along the connecting ring and allow the end of the stapler body to penetrate the puncture core and then extend to the outside.

[0029] In at least one embodiment, the puncture sleeve includes a connecting shell 41, the connecting shell is connected to a tube body 42, an integrally formed annular anti-slip thread 421 is formed on the outer side of the tube body, and four groups of long holes 422 are arranged in a circular array on the tube body, and the long holes are covered with a rubber film 423.

[0030] In conjunction with this, the puncture core includes a puncture inner tube 53, which is a hollow tube.
