AI Technical Summary

Technical Problem

In the prior art, when heating another laparoscopic lens is quickly required, a large amount of heat will still be retained in the heating device. In order to reduce the hot and cold impact, it is necessary to wait for the heating device to cool down, which will cause time waste.

Method used

An electric heating device is designed, using a cover sheet and a thrust mechanism so that the heat in the vertical cylinder can be quickly dissipated, and the rapid heat dissipation of the heating device is achieved through the cooperation of the driving component and the sheet plate.

Benefits of technology

It effectively reduces the waste of heat dissipation time of the heating device, improves the operating efficiency of the heating device, and avoids waste of time caused by hot and cold impacts.

Abstract

The present application relates to the field of medical devices, and discloses an electric heating device for preventing the front end of a laparoscope from fogging, comprising a base plate, a vertical tube located above the base plate, a cover ring fixed to the top surface of the vertical tube, a connecting rod connected between the vertical tube and the base plate, a plurality of vertical holes evenly opened on the circumference of the vertical tube along the circumference of the vertical tube, an electric heating wire installed in each vertical hole, a plurality of cover sheets evenly arranged along the circumference of the vertical tube between the base plate and the cover ring, a pushing mechanism for pushing the plurality of cover sheets to close or open between the bottom of the vertical tube and the base plate, and the interior of the vertical tube for placing a laparoscope lens. The present application solves the technical problem in the prior art that when another lens needs to be heated quickly, a large amount of heat will still be retained in the heating device, and in order to reduce the hot and cold shock, it is necessary to wait for the heating device to cool down, which will cause a waste of time, and realizes that the heating device can quickly dissipate heat to reduce the waste of time.
