Abstract

The invention relates to a fixable laparoscopic puncture outfit. The fixable laparoscopic puncture outfit comprises a sheath tube, and further comprises a fixing structure and a connecting structure connecting the sheath tube with the fixing structure, and the fixing structure can be fixed or move on the sheath tube through the connecting structure in the axial direction of the sheath tube; the fixing structure comprises a fixing tube, an air bag, a liquid / air injecting channel and a liquid / air injecting valve; the fixing tube is arranged outside the sheath tube in a sleeving mode, and the length of the fixing tube is smaller than that of the sheath tube; the air bag is arranged at the front end of the fixing tube; one end of the liquid / air injecting channel is connected with the air bag, the other end of the liquid / air injecting channel protrudes out of the tube wall of the fixing tube, an end port of the liquid / air injecting channel is provided with the liquid / air injecting valve, the liquid / air injecting valve is arranged at the back end of the fixing tube, and a valve port of the liquid / air injecting valve protrudes out of the tube wall of the fixing tube; the air bag and the liquid / air injecting valve are communicated through the liquid / air injecting channel.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a fixable laparoscopic puncture device. Background technique [0002] Laparoscopic surgery is the most widely used minimally invasive surgical method in clinical practice. During the operation, a laparoscopic puncture device is used to puncture the body wall (chest, abdomen, waist, etc.) through the skin, and the front end of the sheath tube of the puncture device is left in the abdominal cavity, thoracic cavity, or retroperitoneal cavity, and then passed through the channel in the puncture sheath tube. Insert surgical instruments to perform corresponding surgical operations on the tissues and organs in the above-mentioned body cavity. The laparoscopic trocar is an instrument that must be used in this operation. There is no effective fixing device after the existing laparoscopic trocar sheath penetrates into the body cavity, and the puncture sheath often falls out of the body ...
