Description

Technical Field

[0001] The utility model relates to the field of surgical instruments, in particular to a multi-channel platform for laparoscopic surgery. Background Art

[0002] With the development of laparoscopic equipment and technology, laparoscopic minimally invasive surgery has been widely used in abdominal surgery. Compared with traditional open abdominal surgery, laparoscopic minimally invasive surgery has outstanding advantages such as minimal invasiveness, safety, aesthetics, and less postoperative pain. It minimizes the impact of surgery on patients, has obvious advantages in reducing postoperative incision pain and abdominal wall paresthesia, and shortens the patient's postoperative recovery period.

[0003] Laparoscopic surgeries include cholecystectomy, total gastrectomy, appendectomy, and intrahepatic bile duct cystadenoma resection. During the operation, the abdominal channel device needs to be connected to the multi-porous operating platform, and the airtightness of the connection must be ensured. Currently, when using the existing abdominal channel device with the multi-porous operating platform, the abdominal channel device is simply inserted into the multi-porous operating platform, or sealed with a rubber band, resulting in poor connection sealing performance. It is easy for the device to fall off or leak during use, affecting the progress of the operation. Therefore, it is necessary to propose a multi-channel platform for laparoscopic surgery.
