The puncture outfit is a common tool in laparoscopic surgery, an inflatable needle is firstly inserted into the umbilical region of a patient during the surgery, and gas is injected into the abdominal cavity at the same time so as to expand the abdominal cavity space, and then the puncture outfit is inserted into the abdominal cavity to form a channel, so that the operation of the surgery is convenient, and the importance of air tightness in the process is obvious. In order to ensure that the air in the abdomen of the patient can not leak in the operation process, the puncture outfit is provided with a sealing structure.
The existing sealing structure has various types, and is commonly a sealing film with a cross-shaped kerf or a cross-shaped kerf, wherein the lengths of all the kerfs of the cross-shaped kerf are equal, when the sealing film is used, a puncture rod can freely penetrate through the sealing film from the kerf, and after the puncture rod is pulled out from the kerf, the sealing film can be quickly restored, so that the sealing environment is restored. However, both sealing films have drawbacks: the straight-line-shaped kerf has less kerf, the sealing film has strong strength and good restoration performance of the opening, but the straight-line-shaped kerf also causes larger resistance to be overcome when the instrument passes through, namely the passing performance is poor; the periphery of the cross-shaped kerf is provided with kerfs, the strength of the sealing film is inferior to that of the sealing film provided with the cross-shaped kerf, so that the instrument can pass through easily, but the sealing film cannot be restored to the original state in time after the instrument leaves, namely, the restoration is poor.
