Problems solved by technology

Although laparoscopic surgery has further reduced the surgical trauma and wounds on the patient's body surface, there are still shortcomings. For single-port laparoscopic surgery, the surgical instruments that need to be placed in the abdominal cavity are all concentrated in a single port, and there will inevitably be interactions between the instruments. Collision and interference affect surgical anatomy, separation and other operations; in addition, in laparoscopic surgery, the puncture of surgical instruments and auxiliary instruments is far away from the surgical operation site, or the fiberscope is needed to reach the operation site, which makes the doctor's operation more difficult.

Abstract

The invention discloses a magnetic auxiliary lighting and photographing device for use in laparoscopic surgery, which comprises a belly wall external magnetic anchoring device and a belly wall lighting and photographing auxiliary device matched with the belly wall external magnetic anchoring device. The lighting and photographing assisting device, under action of magnetic attraction, can effectively reach a surgical operation area flexibly to light and photograph the surgical area; meanwhile, because only a wire instead of a hard pricking card or operating rod is adopted, the operation difficulty of laparoscopic surgery is lowered and the laparoscopic surgery can be performed widely in clinic.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a magnetically assisted lighting and imaging device for laparoscopic surgery. Background technique [0002] Minimally invasive surgical technology is an important trend in the development of today's surgical field. Laparoscopic surgery, especially the transumbilical single-port laparoscopic surgery and natural orifice single-port laparoscopic surgery developed in recent years, is the surgeon's pursuit of ultra-minimally invasive surgery. Practice results. Although laparoscopic surgery has further reduced the surgical trauma and wounds on the patient's body surface, there are still shortcomings. For single-port laparoscopic surgery, the surgical instruments that need to be placed in the abdominal cavity are all concentrated in a single port, and there will inevitably be interactions between the instruments. Collision and interference affect surgical anatom...
