A lighting device for medical endoscopy

Abstract

The invention discloses a medical endoscopy lighting device. The medical endoscopy lighting device comprises a lighting unit, a transmission pipe and a fixing unit, wherein the lighting unit further comprises a light path output end, a light path passage and an LED light source, and the light path output end, the light path passage and the LED light source are sequentially connected and connected with the fixing unit through the transmission pipe; the fixing unit further comprises a power supply box, a sucking disk and a bolt fastening structure, and the sucking disk and the bolt fastening structure are respectively mounted on two sides of the power supply box. Compared with the prior art, the medical endoscopy lighting device disclosed by the invention has the benefits that the medical endoscopy lighting device provided by the invention adopts a manner that a first light guiding part and a second light guiding part are matched, so that light is effectively transmitted to an optical fiber, and enough luminous flux is provided for medical use; a whole endoscopy lamp is simple and light in design, so that the medical endoscopy lighting device has a quite wide application prospect.

Description

technical field [0001] The invention relates to an inspection lighting device, in particular to a medical endoscope inspection lighting device, which belongs to the technical field of medical equipment. Background technique [0002] Medical endoscope inspection lighting device is a kind of medical equipment commonly used in modern medical institutions. It is mainly used in arthroscope, laparoscope and other medical endoscopes in clinical minimally invasive surgery or some ophthalmic medical operations and some daily inspection procedures. . [0003] With the development and popularization of medical optical instruments, especially the wide application of medical endoscopes such as arthroscopes and laparoscopes in clinical minimally invasive surgery, the requirements for the number and characteristics of medical cold light sources are getting higher and higher. The basic function of the medical cold light source is to generate cold light, which can be used as a light source ...

AI Technical Summary

Problems solved by technology

The tungsten halogen lighting used in the early stage has low efficacy and color temperature, and poor color reproduction. Although it can achieve high color temperature at present, because it is a gas discharge lamp, its life is short.

[0004] In the process of ophthalmic medical surgery, it is necessary to illuminate the local position. The lighting method of the prior art usually uses optical fiber to introduce the light emitted by the high-power light source to the part that needs to be illuminated for illumination. The equipment used in this method is complicated to connect and has a large volume. , the operation is inconvenient, and the equipment is relatively expensive

People are more inclined to use portable lighting equipment for lighting. Similar lighting equipment structures are disclosed in Chinese invention patent CN200820046975.8, which includes a light cylinder body and a driver LED light source placed in the light cylinder body. And heat sink, also includes optical fiber and the concentrating system placed in the light cylinder, the LED light source is set at the light path input end of the light concentrating system, the optical fiber is set at the light path output end of the light concentrating system, this structure is suitable for general portable LED optical fiber Lighting equipment, light intensity and structural form used during surgery are not fully applicable

[0005] To sum up the above situation, the current domestic medical endoscopy lighting devices mainly have the following deficiencies: 1. Insufficient luminous flux and poor color reproduction; 2. Poor heat dissipation, complicated equipment connection, large volume and inconvenient operation; 3. Single fixing method, applicable narrow range
