Description

Technical Field

[0001] The utility model relates to a trocar for laparoscopic surgery, and more particularly to a multi-channel single-port laparoscopic surgery trocar. Background Art

[0002] A single-port laparoscopic surgery trocar is a special instrument for single-port laparoscopic surgery. The instrument usually consists of a central trocar and multiple laterally connected channels. The doctor inserts the single-port laparoscopic surgery trocar into the abdominal cavity through it, and then inserts other surgical tools, such as a camera, a suction device, an electrocoagulation knife, etc., through the lateral channels to complete the surgical operation.

[0003] Currently, for the existing single-port laparoscopic surgery trocar, the doctor inserts it into the abdominal cavity through the single-port laparoscopic surgery trocar, and inflates the abdominal cavity through a pneumoperitoneum machine. In order to ensure the airtightness between the single-port laparoscopic surgery trocar and the abdominal cavity, the airtightness between the two is usually ensured by a sealing sleeve. However, inflating the abdominal cavity will cause the airtightness of the sealing sleeve to decrease, thereby affecting the progress of the surgery.

[0004] In view of the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model
