Laparoscope umbrella-shaped anastomat

Abstract

The laparoscope umbrella-shaped anastomat comprises a handle, a main body is arranged on the left side of the handle, a driving structure is arranged at the bottom of the handle, the main body comprises a circular tube, a nail abutting seat and an anastomat body, the circle center of the nail abutting seat is movably connected with the outer wall of a first circular ring, and first steel bars aremovably installed on the outer wall of the nail abutting seat. The outer ends of the first steel bars are movably connected with the inner wall of the nail abutting seat, first round bars are welded to the inner wall of a third ring, and the circle center of the anastomat body is movably connected with the outer wall of the third ring. According to the scheme, for the obese patients with relatively high difficulty in operation and narrow space, enough incisal edges need to be excised, and the laparoscope umbrella-shaped anastomat breaks through the narrow space of a laparoscope puncture hole by means of the advantages of laparotomy circular anastomosis, and achieves circular anastomosis under a laparoscope; circular anastomosis is achieved under a laparoscope, abdominal wounds are minimally invasive, and under the same condition, anastomosis of the laparoscope umbrella-shaped anastomat is minimally invasive compared with any previous anastomosis method. Meanwhile, side injuries of other anastomosis methods are avoided, the operation time is shortened, and a patient is effectively prevented from being infected by bacteria.

Description

technical field [0001] The invention belongs to the technical field of staplers, in particular to a laparoscopic umbrella energy stapler. Background technique [0002] At present, laparoscopic technology has been widely carried out, especially laparoscopic gastrointestinal tumor resection. After tumor resection, it involves the reconstruction of the hollow viscera of the digestive tract, such as laparoscopic total gastrectomy. The key problem is the digestive tract after total gastrectomy. For tract reconstruction, most surgeons choose to operate under auxiliary incision. For laparoscopic operation, most doctors choose side-to-side anastomosis with linear cutting closer. The main disadvantage is that the lower end of the esophagus needs to be kept longer, and the resection margin is limited, so it is not suitable for patients with a high esophagus resection line. For jejunoesophageal anastomosis, some doctors also use the circular stapler method [transoral insertion of an...

AI Technical Summary

Problems solved by technology

[0003] The disadvantage of end-to-side anastomosis with a circular stapler is that the main body of the stapler cannot enter the abdominal cavity through the trocar hole, and the pneumoperitoneum must be closed and an auxiliary small incision can be made to insert it, which reduces the smoothness and appreciation of the operation

Moreover, the traditional stapler has poor antibacterial performance and is easy to breed bacteria, which is not conducive to the health of patients.
