Laparoscope

Abstract

The invention discloses a laparoscope, and relates to the technical field of medical apparatus. The laparoscope comprises a laparoscope outer sleeve (1), fixed support devices, a movable inner tube device and an electronic lumen camera component, wherein a through hole (1-1) from which an inner tube runs through, an air vent (1-2) for forming pneumoperitoneum and a liquid-injection hole (1-3) for forming a liquid operating environment are formed in the laparoscope outer sleeve (1); each of the fixed support devices comprises a trocar main body (2) and a ball bearing (3); through holes, which are used for assembling the ball bearings, are formed in the trocar main bodies (2); and bosses (2-1), which are used for clamping abdominal incision holes, are arranged outside the trocar main bodies (2). The laparoscope disclosed by the invention is simple and reasonable in structural design and convenient to operate; the laparoscope is capable of assisting abdominal surgeries, acquiring images in abdominal cavities within a large range and forming the pneumoperitoneum, and in addition, the laparoscope is also capable of injecting normal saline into abdomens by virtue of the liquid-injection hole, so that a liquid environment is formed for the surgeries; and the laparoscope has good application and popularization values.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a laparoscope. Background technique [0002] A laparoscope is a medical device with a tiny camera. In the prior art, the diameter of the mirror tube of the laparoscope is small, so that the diameter of the instrument channel in the laparoscope is also small, and only some simple surgical instruments are allowed to pass through during the operation. The operation channel is re-opened on the body to increase the pain of the patient; in addition, most of the current laparoscopic operations use gas as the medium. Operate in an atmosphere of gas. [0003] Existing laparoscopes generally cannot be moved after the arrangement is completed, which results in limited picture angles that can be photographed by the lens of the laparoscope, which affects the operation. Contents of the invention [0004] The purpose of the present invention is mainly to provide a laparoscope i...
