Tractive opening device for abdominal cavity walls

Abstract

The invention relates to a tractive opening device for abdominal cavity walls. The device comprises a hollow tube channel, the tube channel is sleeved with a mobile end which can slide up and down, and an opening device body is arranged at the far end of the tube channel; the opening device body is connected to the bottom of the mobile end through a flexible rope, and opening or closing of the opening device body is controlled through up and down sliding of the mobile end. The tractive opening device for the abdominal cavity walls is simple in structure and reliable and does not fall off easily, a single hand can operate the device, under the locking state, various angles can be formed between the opening device body and the abdominal cavity walls, various operation angles are provided, and the peritoneoscope operation is conducted conveniently. According to the tractive opening device for the abdominal cavity walls, the tube channel provides space for in and out of laparoscopic instruments, the situation is avoided that more holes are formed in the abdominal cavity walls, and the damage to the abdominal cavity walls of the human body is reduced. Artificial pneumoperitoneum is not needed to be built any more, and complications caused by artificial pneumoperitoneum are avoided, so that patients who cannot tolerate severe cardiopulmonary dysfunction of pneumoperitoneum and old patients can be subjected to peritoneoscope operation successfully.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a pull-type abdominal wall spreader. Background technique [0002] Laparoscopic surgery has been widely used in abdominal surgery. Compared with traditional surgery, laparoscopic surgery has the advantages of less surgical trauma, easy postoperative recovery, less pain, less disturbance to abdominal viscera, less incision infection or fat liquefaction. At present, before laparoscopic surgery, an artificial pneumoperitoneum is mostly used to separate the peritoneal wall from the viscera, and the abdominal cavity is expanded accordingly to provide a surgical space and avoid damage to the viscera when the trocar is punctured into the abdominal cavity. But high pressure C0 2 Increased cardiopulmonary burden, due to C0 2 easy solubility, a large amount of C0 2 If the absorption is not eliminated in time, the acid-base balance of the body fluid will be disturbed. High-pressu...

Problems solved by technology

But high pressure C0 2 Increased cardiopulmonary burden, due to C0 2 easy solubility, a large amount of C0 2 If the absorption is not eliminated in time, the acid-base balance of the body fluid will be disturbed. High-pressure pneumoperitoneum will also cause discomfort such as abdominal distension and dyspnea, which may even be unbearable. Belly will bring great danger

Therefore, the abdominal wall spreader has appeared, but the structural design of the existing abdominal wall spreader on the market is unreasonable. Some spreaders are easy to fall off during the operation and cause secondary damage, and some use process will cause abdominal wall. Certain injuries, and some complex operations, which increase the difficulty of surgery
