Channel device for multichannel single-hole laparoscopic surgery

Abstract

The invention relates to a channel device for a multichannel single-hole laparoscopic surgery and belongs to the field of medical appliances. The channel device is applicable to matched use with a multichannel single-hole laparoscope, is an endoscope-matched surgical instrument, is applied to laparoscopic surgeries and minimally-invasive surgeries and is used for extending a visual field of surgical operation, protecting an incision from injury and reducing incision infection. The channel device comprises a snap ring fixing ring, a detachable-connected handle, a channel ring body and a channelimplantation fixing ring; the snap ring fixing ring is arranged at the upper part of the channel ring body, the detachable-connected handle is arranged at the upper end of the snap ring fixing ring,and the channel implantation fixing ring is arranged at the lower part of the channel ring body; and a mounting guiding circular arc is arranged on the snap ring fixing ring, a locating snapping groove is formed below the snap ring fixing ring and is connected with the mounting guiding circular arc through a sealed fixing ring, a step is formed by the locating snapping groove and the sealed fixingring and is right-angled, the inside diameter of the snap ring fixing ring is smaller than the outside diameter of a locating mounting groove of a sealed snap ring plate, and a sealed snapping buckleis mounted in the locating mounting groove of the sealed snap ring plate.

Description

technical field [0001] The invention relates to a channel device for multi-channel single-hole laparoscopic surgery in the field of medical instruments, which is suitable for matching with multi-channel single-hole laparoscope, and is an endoscope matching surgical instrument for laparoscopic surgery and minimally invasive surgery It is used to expand the surgical field of view, protect the incision from damage and reduce incision infection. Background technique [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 minimal invasiveness and safety. , aesthetics, less postoperative pain and other high-quality features, which minimize the impact of surgery on patients, have obvious advantages in reducing postoperative incision pain and abdominal wall paresthesia, and shorten...
