Embodiment 1

[0018] Such as figure 1 As shown, the present invention provides a laparoscopic lens anti-fog device, including a laparoscope, the laparoscope includes a lens 5, a mirror body 1 and a handle 2, and the lens 5 is arranged on the mirror body 1 The front end of the mirror body 1 is connected to the handle 2, and a rubber pad 3 is arranged on the outside of the mirror body 1, and a thermochromic additive is distributed in the rubber pad 3, and a part of the rubber pad 3 An arc-shaped groove 4 is provided on the side, and the arc-shaped groove 4 is arranged in cooperation with the outside of the mirror body 1 .

[0019] Further, the rubber pad 3 is a cuboid.

[0020] Further, the arc-shaped groove 4 is semi-cylindrical.

[0021] Specifically, the laparoscope also includes a light source assembly and an optical fiber assembly, both of which are prior art, and will not be repeated here.

[0022] Specifically, the rubber pad 3 has elasticity and toughness, is not easy to drop slag ...

Abstract

The invention relates to a laparoscope lens antifogging method, includes a process of heating a laparoscope lens body, repeatedly rubs an outer surface of the laparoscope lens body with a thermochromic rubber pad, heats the laparoscope lens body through utilizing heat generated through friction, on the basis of the heat transfer principle, further heats the lens of a laparoscope and achieves the antifogging effect of the laparoscope lens. The invention further provides a laparoscope lens antifogging device, the laparoscope lens antifogging device comprises the laparoscope, wherein the laparoscope comprises the lens, a body and a handle, the lens is arranged at a front end of the body, the body and the handle are connected, an outer side of the body is provided with a rubber pad, the rubberpad is distributed with thermochromic additive, one side of the rubber pad is provided with an arc-shaped groove, and the arc-shaped groove is matched with the outer side of the body. The laparoscopelens antifogging method and device are advantaged in that the frictional heat generation principle is utilized, the laparoscope lens is heated to the temperature to prevent water vapor in the abdominal cavity from condensing due to coldness before the lens, and thereby the antifogging effect of the lens is achieved, and the laparoscope lens antifogging method and device are simple, fast, economical and practical.

Description

technical field [0001] The invention relates to articles for human life, in particular to medical instruments, in particular to a laparoscope, in particular to a laparoscope lens anti-fog method and an anti-fog device. Background technique [0002] Laparoscopic surgery has the advantages of less trauma and faster postoperative recovery, and has been widely used in surgical operations. A clear surgical field of view is the premise to ensure the quality of the operation, which can shorten the operation time and reduce the intraoperative injury. However, in laparoscopic surgery, due to the temperature difference between the lens temperature and the temperature in the abdominal cavity, it is easy to cause lens fogging. Lens fogging will affect the operator's field of vision, prolong the operation time, and increase the risk of operation. Therefore, the anti-fog technology of laparoscopic lens in laparoscopic surgery is the key to ensure the quality of surgery. [0003] The re...
