Description

Endoscope lens cleaner

Technical Field

The utility model belongs to the technical field of medical scope washs medical instrument technique and specifically relates to a scope camera lens purger.

Background

Endoscopic minimally invasive surgery is a common surgical approach at present. At present, in clinical operation, the lens of the nasal endoscope is often polluted by blood, secretion and the like in the nasal cavity, or the lens is fogged due to the temperature difference between the inside and the outside of the nasal cavity, so the lens needs to be cleaned in the operation. These factors can seriously affect the visual field of the operator, and the operator cannot see the operation cavity clearly, which affects the normal operation of the operation.

The retrieval patent CN201220090612.0 discloses an intraoperative nasal endoscope lens cleaner, which mainly comprises a cleaning tube, wherein at least two fixing clamps or fixing sleeves are fixedly connected on the cleaning tube, and the lower end of the cleaning tube is provided with an inclined liquid outlet; the upper end of the cleaning pipe is communicated with a liquid storage bag, the upper part of the liquid storage bag is communicated with a liquid injection pipe, and the upper end of the liquid injection pipe is provided with a connecting joint. The patent mainly solves the problem that nasal bleeding and nasal secretion cause the blurring of the nasal endoscope lens. But the problem of lens fogging caused by the temperature difference between the inside and the outside of the nasal cavity cannot be solved by the nasal endoscope. The patent CN201010540947.3 discloses a nose endoscope heating antifogging device, which comprises an endoscope body and an endoscope handle, wherein the endoscope body is provided with a metal heating ring and a temperature sensor which are connected by leads, and the metal heating ring is internally provided with a resistance heating device. The problem that fog is easily produced in the operation process of the nose endoscope is mainly solved, but the heating antifogging device cannot solve the problem that the nose endoscope lens is fuzzy due to nasal bleeding and nasal secretion. Chinese utility model patent CN201621461277.5 discloses a camera lens belt cleaning device, including purger main part, apron, heating device, the four bibliographic categories branch, this patent has solved the nasal cavity and has bled and nasal cavity secretion leads to the nose endoscope camera lens fuzzy and leads to the camera lens scheduling problem that hazes because of the inside and outside difference in temperature problem of nasal cavity. However, the cleaning force of the device is not large, which can cause incomplete lens washing in the cleaning process and easily affect the operation.

In addition, different hospitals propose different proposals, including the technical assistant in the operation to assist the main knife to clean the wiping lens. The implementation of this solution has limitations, not only wasting manpower, but also damaging the lens by long-time wiping.

Therefore, there is a need for an endoscope lens cleaning device capable of solving the problems of endoscope lens blur caused by endoscope lens pollution and internal and external temperature difference fogging during operation, and having a strong effect without assistant-assisted operation, and no report is found about the novel endoscope lens cleaning device at present.
