A trocar puncturing assisting instrument

Abstract

The invention provides a trocar puncturing assisting instrument comprising an operating rod. A lower protecting sheet, an upper protecting sheet and a locating device are arranged on the operating rodfrom bottom to top successively; an adjusting device for adjusting the distance between the upper protecting sheet and the lower protecting sheet is arranged; the middle portion of the upper protecting sheet is provided with channels allowing passing of a trocar. The trocar puncturing assisting instrument has the advantages that, after the upper protecting sheet and the lower protecting sheet areplaced between corresponding abdominal wall layers for building of a space of an abdominal wall cut, the upper protecting sheet can be adjusted upward to make the upper protecting sheet be a certaindistance away from the lower protecting sheet, so that a certain operating space is maintained during trocar puncturing; the locating device is used for location outside a human body; the trocar can penetrate from the channel accurately, so that the operation is simple; the lower protecting sheet can protect peritoneum, so that the trocar puncturing difficulty is reduced, the success rate of surgery is increased and surgery time is remarkably reduced. The trocar puncturing assisting instrument belongs to the field of medical instruments.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a card-punching auxiliary device. Background technique [0002] At present, the incidence of inguinal hernia is very high, and inguinal hernia surgery includes open surgery and laparoscopic surgery. At present, the mesh is placed in the preperitoneum. Before entering the peritoneum, place the patch into the preperitoneal space. [0003] A key step in this operation is the establishment of a channel for the laparoscope and instruments to enter the preperitoneal space, the establishment of a complete preperitoneal space, and the formation of a closed cavity. Lifting tissues other than the peritoneum, including the skin, subcutaneous tissue, linea alba, or the anterior sheath of the rectus abdominis muscle and the rectus abdominis muscle for puncture placement, often causes finger injuries of physicians, especially those who are inexperienced, or punctures the peritoneum. The establ...

Problems solved by technology

[0003] A key step in this operation is the establishment of a channel for the laparoscope and instruments to enter the preperitoneal space, the establishment of a complete preperitoneal space, and the formation of a closed cavity. Lifting tissues other than the peritoneum, including the skin, subcutaneous tissue, linea alba, or the anterior sheath of the rectus abdominis muscle and the rectus abdominis muscle for puncture placement, often causes finger injuries of physicians, especially those who are inexperienced, or punctures the peritoneum. The establishment of the airtight preperitoneal space fails, causing part of the gas to enter the abdominal cavity, resulting in a very narrow operating space, which significantly increases the difficulty of the operation and prolongs the operation time. In the case of insufficient exposure, it is easy to accidentally injure important structures and organs during the operation. Even conversion to open surgery is required
