Abstract

The invention discloses a seal assembly for a puncture outfit. The seal assembly comprises a seal film and a seal protection part. The seal film comprises a seal hole, and an instrument inserted in the seal hole is sealed by the seal film; the seal protection part is close to the seal film and used for protecting the seal film from being damaged by the instrument and comprises one or more press fit plates; each press fit plate comprises a near-end opening, a far-end hole and a protection wall which extends from the near-end opening to the far-end hole; each protection wall comprises two or more slits which extend horizontally from the corresponding far-end hole, the slits can allow the protection walls to deform so that the far-end holes can expand, and the instrument penetrates through the far-end holes conveniently. According to the seal assembly for the puncture outfit, the seal film can be effectively protected and prevented from being scratched or torn by the sharp edge of the instrument, the protection walls of the seal protection part are simple in structure, the number of the protection walls is small, and accordingly assembly is easy.

Description

technical field [0001] The invention relates to a minimally invasive surgical instrument, in particular to a sealing assembly and a trocar with the same. Background technique [0002] A trocar is a surgical instrument used to establish an artificial channel into a body cavity in minimally invasive surgery (especially hard tube endoscopic surgery). Usually consists of a cannula assembly and a puncture needle. Its general clinical use method is: first cut a small opening on the patient's skin, then pass the puncture needle through the cannula assembly, and then penetrate the abdominal wall through the skin opening and enter the body cavity together. Once in the body cavity, the needle is removed, leaving the cannula assembly as a channel for the instrument to enter and exit the body cavity. [0003] During endoscopic surgical procedures, an insufflation fluid, such as carbon dioxide or saline, is typically injected into a patient's body cavity, thereby providing sufficient o...
