Abstract

The present invention relates to the field of medical devices, and discloses a sealing structure and a puncturing device. The sealing structure comprises a sealing main body and a sealing film, wherein a cavity is arranged inside the sealing main body, openings are formed at both ends of the sealing main body, openings at least at one end of the cavity are closed by the sealing film, a first seampenetrating the sealing film is arranged on the sealing film, and at least one side of the first seam is provided with a second seam which is shorter than the first seam and intersects with the firstseam. Compared with the sealing structure of the prior art having a linear shaped seam and a cross-shaped seam, the sealing structure of the present invention has the advantages of both passing and restoring properties, simple structure and easy realization by opening a second seam which is shorter than the first seam and intersects the second seam on the sealing film and penetrating the sealing film.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a sealing structure and a trocar using the sealing structure. Background technique [0002] The puncture device is a common tool in laparoscopic surgery. During the operation, an inflatable needle is first inserted into the patient's umbilical area, and gas is injected into the abdominal cavity at the same time to expand the abdominal cavity space, and then the puncture device is inserted into the abdominal cavity to form a channel. , to facilitate the operation of the operation, the importance of air tightness in this process is obvious. In order to ensure that the gas in the patient's abdomen will not leak during the operation, the trocars are all provided with a sealing structure. [0003] There are many types of existing sealing structures, and the most common ones are sealing films with "one-shaped" slits or "cross-shaped" slits, wherein the lengths of each cut in the "cros...
