Disposable portable hysteroscope

Abstract

The invention discloses a disposable portable hysteroscope. The disposable portable hysteroscope comprises a front section, a rear section and a middle part connecting the front section and the rear section; the front section and the middle part are packaged together and are non-detachable; the front section and the middle part are disposable; the front section comprises an optical lens set which is inserted into a uterus; the radial size of the front section is less than 4mm; the middle part comprises a camera module and a prism; the radial size of the camera module is more than 3mm; and the resolution ratio of the camera module is more than one million pixels. The hysteroscope integrates the advantages of a traditional optical hysteroscope and a traditional electronic hysteroscope, the superfine optical lens set is used in the front section to achieve image conduction, a high-definition image sensor is used in the middle part, the front section is small in size and can enter a uterus part, anesthesia is not needed, and clear image transmission can be achieved due to the optical lens set. Therefore, the hysteroscope has the advantages of the traditional optical hysteroscope and the traditional electronic hysteroscope, and is low in price, disposable and safer.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a disposable portable hysteroscope. Background technique [0002] There are two types of existing hysteroscopes, one is an optical mirror, the front end of the optical mirror is a glass lens group, and the rear end is a large-size CMOS image sensor; the other is an electronic mirror, and the electronic mirror is directly packaged with a miniature lens at the front end. CMOS image sensor. [0003] Existing optical mirrors have the following defects: [0004] 1. The volume is large, and anesthesia is required during the operation. Due to the limitations of the optical structure, the size of the common hysteroscopic optical mirrors is >5mm, so it is impossible to directly enter the uterus through the natural orifice for observation, and a uterine dilation operation must be performed, so the patient needs to be anesthetized and hospitalized, and cannot be operated in an outpatie...

AI Technical Summary

Problems solved by technology

Due to the limitations of the optical structure, the size of the common hysteroscopic optical mirrors is >5mm, so it is impossible to directly enter the uterus through the natural orifice for observation, and a uterine dilation operation must be performed, so the patient needs to be anesthetized and hospitalized, and cannot be operated in an outpatient clinic. ;

[0005] 2. The existing hysteroscopic optical mirror has a complex structure. The overall structure includes: hysteroscope, energy system, light source system, perfusion system and imaging system. The overall price of the electronic system is relatively expensive. Although the rear CMOS image sensor can achieve high-definition Images, but larger in size and more expensive;

[0006] 3. The insertion part at the front end of the existing hysteroscope optical mirror and the handle part at the rear end are detachable. Since the insertion part at the front end is a structure of glass lens and stainless steel mirror sheath, the insertion part at the front end can be removed for disinfection and reuse , the handle at the back end does not touch the human body, just wipe and disinfect, but there is a certain proportion of incomplete disinfection during actual operation, which may easily lead to cross-infection;
