Description

Technical Field

[0001] The utility model belongs to the technical field of laparoscopes, and in particular relates to a laparoscope columnar magnetic adsorption device. Background Art

[0002] Children are very curious and may swallow metal needles by mistake. Metal needles that enter the digestive tract are easy to wander. Affected by factors such as the route of entry into the body and the length of medical history, metal needles may be located in the wall of the digestive tract, in the abdominal cavity, or may migrate to solid organs or retroperitoneal spaces. In addition, during laparoscopic surgery, suture needles with cut ends may sometimes fall into the abdominal cavity or accidentally break off from the needle holder. The above-mentioned situations cause metal needles to fall into the abdominal cavity, intestinal wall, intestinal space, etc., and they can move with normal intestinal peristalsis. Preoperative or intraoperative imaging examinations can only provide the approximate location of the metal needle. The search process is like "finding a needle in a haystack", which is a difficult point in surgical treatment.

[0003] A Chinese patent with application number CN2021112616137 discloses a laparoscopic magnetic anastomotic ring fixer, which consists of a handle, a connecting part, an opening and closing joint and a clamping part. The handle drives the connecting part and the opening and closing joint to control the opening and closing of the clamping part, thereby realizing the clamping of the laparoscopic magnetic anastomotic ring. The linkage design of the opening and closing joint and the annular design of the clamping part corresponding to the shape of the laparoscopic magnetic anastomotic ring make the clamping part close to the laparoscopic magnetic anastomotic ring, which can ensure the stability during vascular anastomosis, and can effectively shorten the anastomosis time and reduce the risk of organ tissue damage.

[0004] However, it can only clamp the clamped object. When the laparoscope is removed, the clamped object is still easy to scratch the inner wall of the patient's internal organs, causing secondary damage.

[0005] In view of this, this application is hereby filed. Utility Model Content
