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.
