Laparoscope with liquid sucking function and with extension and retraction convenient to adjust

Abstract

The invention discloses a laparoscope with a liquid sucking function and with extension and retraction convenient to adjust. The laparoscope comprises a handle and a control device, a locating block is connected to the handle in a sliding mode, a rod body is arranged in the handle, a camera device is connected to the end, away from the handle, of the rod body in a rotating mode, a wire is arrangedat the end, away from the rod body, of the handle, and the handle is electrically connected with the control device through the wire; a liquid accumulation device is fixedly connected to the handle,a liquid accumulation cavity is formed in the liquid accumulation device, the liquid accumulation cavity is communicated with a liquid sucking pipe, and the liquid sucking pipe is fixedly connected with the handle; a piston is arranged in the liquid accumulation cavity, the piston is connected with a limiting block through a piston rod, and the limiting block penetrates the liquid accumulation device and extends to the handle. According to the laparoscope, the structure is stable, and the shooting angle of the camera device can be adjusted, so that the shooting range is increased; extension and retraction of the rod body can be adjusted, and the rod body can go deeply into an abdominal cavity, so that use is more flexible; the laparoscope is provided with the liquid accumulation device, and waste liquid influencing observation in the abdominal cavity can be discharged.

Description

technical field [0001] The invention relates to the technical field of laparoscopy, in particular to a laparoscope with a liquid suction function and convenient for telescopic adjustment. Background technique [0002] Minimally invasive surgery is the most cutting-edge development direction of medical science and technology today. Minimally invasive surgery represented by laparoscopic surgery has gradually replaced traditional laparotomy. After more than 20 years of development, the technique of laparoscopic minimally invasive surgery has gradually matured. Because of its small surgical trauma, mild postoperative pain, short hospital stay, and good cosmetic effect, it has been widely used and satisfied in clinical practice. Effect. Conventional laparoscopic surgery is accomplished through multiple (3-5) tiny (5-12mm) incisions. With the enrichment of clinical experience and the advancement of engineering technology, the concept of minimally invasive surgery has recently bee...
