Description

technical field [0001] The invention relates to a multifunctional outer sealing device specially used for a medical operation puncture device, which belongs to the technical field of medical instruments. Background technique [0002] In minimally invasive laparoscopic medical surgery, the trocar is a special operating channel for surgical instruments to enter the human body. When the instrument passes through the trocar, it is filled with CO 2 When in the human body cavity, the trocar must be able to provide a reliable sealing effect. The realization of the sealing function when the instrument enters and exits the trocar is accomplished by two sets of inner sealing devices and outer sealing devices with different structures. The outer sealing device mainly provides sealing when the instrument enters the patient's body through the trocar; the inner sealing device mainly provides sealing when the instrument leaves the patient's body through the trocar. [0003] see figure 1...
