Abstract

The invention discloses a sealing film for a puncturing device. The sealing film includes a proximal opening, a distal opening and a sealing wall extending from the distal opening to the proximal opening. The distal opening is formed by a sealing lip for accommodating an inserted apparatus and forming hermetic seal. The sealing wall comprises a plurality of corrugation regions, each of the corrugation regions comprises a plurality of corrugation units, the corrugation units extend laterally from the distal opening, and each of the corrugation units includes corrugation peaks and corrugation valleys; and in terms of the extension length, the vertical distances from the corrugation peaks and the corrugation valleys of corrugation unit are equal. Corrugations arranged at the distal opening can increase the circumferential perimeter, sealing for laparoscopic instruments of different diameters can be provided, demolding during manufacturing is facilitated, and processing and manufacturing are facilitated.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a trocar and a sealing assembly thereof, belonging to the field of medical instruments. Background technique [0002] The use of endoscopic procedures in surgery has been widely accepted and offers many advantages over traditional open surgery, including less trauma, faster healing, and a reduced risk of infection. A trocar is a surgical instrument used to establish an artificial channel into a body cavity in endoscopic surgery, and usually consists of a cannula assembly and a puncture core assembly. Its general clinical use method is: first cut a small opening on the patient's skin, then pass the puncture core assembly through the cannula assembly, and then drive the cannula assembly to penetrate the abdominal wall through the skin opening and enter the body cavity. Once in the body cavity, the puncture core assembly can be removed, leaving the cannula assembly as a passage for the inst...
