Embodiment 1

[0035] The cavity mirror lens anti-fog device in the present embodiment, as figure 1 - Figure 5 As shown, it is sheathed on the outside of the outer tube 3 of the endoscope 2 and includes an air blowing tube 1 and a positioning mechanism 5 connected to the blowing tube 1 .

[0036] The blowing tube 1 is sleeved outside the outer tube 3 of the endoscope 2, and an air blowing cavity is formed between the blowing tube 1 and the outer tube 3, and the gas blown out of the blowing cavity is directed toward the outer tube 3 front end. In order to make the blown gas more uniform and form a gas barrier around the end of the outer tube 3, the blowing cavity is set around the outer tube 3, and the blowing tube 1 and the outer Tube 3 is arranged coaxially.

[0037] The position of the end of the blowing end 4 of the blowing tube 1 and the end of the outer tube 3 is set according to the use requirements, such as the end of the blowing end 4 of the blowing tube 1 and the outer tube 3 T...

Embodiment 2

[0044] The endoscope in this embodiment has an outer tube 3 extending into the human body, and the anti-fog device for the lens of the endoscope described in the first embodiment is sheathed on the outer side of the outer tube 3 . The setting of the anti-fog device can effectively prevent the blurring of the lens image due to the condensation of moisture, fat particles, and human tissue on the lens during the use of the endoscope 2 .

Abstract

The invention relates to the technical field of medical instruments, in particular to an endoscope lens anti-fog device and an endoscope. The device comprises an air blowing pipe, which sleeves the outer side of an outer pipe of the endoscope; an air blowing cavity is formed between the air blowing pipe and the outer pipe; and air blown out of the air blowing cavity faces the front end of the outer pipe. Air blown out of the air blowing cavity can prevent steam, fat particles, human tissue and the like from getting close to the lens, so that image blurring caused by steam, fat particles, humantissue and the like condensed at the lens is avoided. Due to the arrangement of the anti-fog device, the normal use of the endoscope is effectively ensured; the operation visual field is clear; the operation accuracy of an operator is improved; the case that a doctor needs to pull the endoscope out of the body for many times to wipe the lens due to fogging, dirt and the like of the endoscope lensand then needs to insert the endoscope into the body again to search for an operation part again is avoided, thus saving the operation time is saved and smoothing the operation.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an anti-fog device for a laparoscopic lens and an endoscope. Background technique [0002] Medical endoscopes have been widely used clinically, especially in recent years, with the development of minimally invasive surgery, they have been rapidly popularized. The main materials of medical endoscopes are glass, metal, etc., and their heat transfer coefficients are very different from those of human tissues. It is easy to condense on the lens surface of the endoscope, resulting in fogging and affecting image quality. Also, surgical instruments such as electrocution and electrocoagulation commonly used in modern surgical operations will produce certain smoke during use, which contains fat particles, human tissue, etc. in addition to water vapor, and these smoke are also easy to condense on the lens of the endoscope. surface, affecting image quality. [0003] The foggi...
