Anti-pollution type minimal invasive surgery laparoscope with adjustable angle

Abstract

The invention discloses an anti-pollution type minimal invasive surgery laparoscope with adjustable angle. The anti-pollution type minimal invasive surgery laparoscope comprises an anti-pollution cleaning nozzle, an angle adjusting assembly, a rod body and an atomizing spray nozzle, wherein the angle adjusting assembly is fixed to the inner part of the rod body; and a lens housing is connected toone end of the angle adjusting assembly. According to the anti-pollution type minimal invasive surgery laparoscope disclosed by the invention, through rotating a second adjusting bolt, a fixing clamping rod is inserted in a fixing clamping seat; the lens housing is fixed to the rod body, so that the lens housing cannot be bent; the second adjusting bolt is rotated in the opposite direction to enable the fixing clamping rod to be separated from the fixing clamping seat; through rotating different first adjusting bolts, an adjusting steel wire rope is pulled by the first adjusting bolts; the lens housing and the rod body are bent caused by the different length of the adjusting steel wire rope, so that the angle adjusting of the laparoscope lens is realized, and the observation of affected part is convenient; and the atomizing spray nozzle is connected with an external medical alcohol atomizer through a connecting pipe, the atomized alcohol is sprayed out from the atomizing spray nozzle to clean the lens surface, and the cleaned alcohol is used for sterilizing, and infection is avoided.

Description

technical field [0001] The invention belongs to the technical field of laparoscopy, in particular to an angle-adjustable antifouling type minimally invasive laparoscope. Background technique [0002] Laparoscope is similar to electronic gastroscope, which is a medical device with a miniature camera. Laparoscopic surgery is the operation performed using laparoscope and related instruments. [0003] Cut the skin at the lower edge of the navel chakra 1 cm, insert the Veress needle at 45 degrees from the incision, withdraw the blood and connect a needle tube, if the normal saline flows in smoothly, it means that the puncture is successful and the needle is in the abdominal cavity. Connect to a CO2 inflator, the intake speed should not exceed 1L / min, and the total amount should be 2-3L. The intra-abdominal pressure does not exceed 2.13KPa (16mmHg). The laparoscope needs to be inserted into the abdominal cavity from the trocar, and the trocar needs to be inserted first. The lap...
