Umbrella stapler for laparoscopy

Abstract

The invention discloses an umbrella type anastomat for a laparoscope. The umbrella type anastomat comprises a regulating mechanism, a first supporting mechanism, a second supporting mechanism and a fixed shell body, wherein the regulating mechanism is arranged at one end of the fixed shell body, the first supporting mechanism and the second supporting mechanism are arranged at one end, far away from the regulating mechanism, of the fixed shell body, the regulating mechanism is composed of the fixed shell body, an adjusting handwheel, a cutting control handle, an interlocking lever, a control switch, an adjusting threaded hole, a center rod, a limiting groove and a limiting block, the center rod is connected inside the fixed shell body in a sliding manner, and one end of the fixed shell body is rotatably connected with the adjusting handwheel. The umbrella type anastomat for the laparoscope, disclosed by the invention, is compact in structure, and linear-circular conversion of the anastomat is achieved by using an umbrella rod of an umbrella cover structure; a circular anastomosing method is carried out under a laparoscope, operations are completely the same as laparotomy operations, a small space of a puncture hole of the laparoscope is broken through, circular anastomosing under the laparoscope is achieved, and a wound of an abdominal region is minimally invasive; and meanwhile, secondary injuries caused by other anastomosing methods are avoided, the time of surgical operation is shortened, and wound healing is facilitated.

Description

technical field [0001] The invention relates to a stapler, in particular to an umbrella-shaped stapler for laparoscopic use, and belongs to the technical field of staplers. 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 reconstruction of the esophagus, most surgeons choose to operate under the assisted incision. For laparoscopic operation, most doctors use a straight line cutter for side-to-side anastomosis. It is suitable for patients with a high esophagectomy line, and some doctors use the circular stapler method for jejunoesophageal anastomosis. [0003] The disadvantage of end-to-side anastomosis with a circular stapler is that the main body of the stapler canno...

Problems solved by technology

[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 reconstruction of the esophagus, most surgeons choose to operate under the assisted incision. For laparoscopic operation, most doctors use a straight line cutter for side-to-side anastomosis. It is suitable for patients with a high esophagectomy line, and some doctors use the circular stapler method for jejunoesophageal anastomosis

[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 puncture hole of laparoscopic surgery, and the pneumoperitoneum must be closed and an auxiliary small incision can be inserted, which reduces the smoothness of the operation
