Video vaginal speculum with connecting ring

Abstract

The invention discloses a video vaginal speculum with a connecting ring. The video vaginal speculum comprises a handle and a speculum lens, wherein the connecting ring is arranged on the speculum lens, the connecting ring sleeves the outer peripheral side of the handle, the connecting ring is in clamping connection with the handle through a clamping piece, clamping gaps extending axially are arranged on the side wall of the connecting ring and on the outer sides of two ends of the clamping piece arranged on the connecting ring, one end of each clamping gap is open, the other end of each clamping gap is closed, the open ends of the clamping gaps are far away from the speculum lens, the clamping piece comprises a clamping hook and a clamping groove matched with the clamping hook, and the side wall of the end part of one end of the clamping groove is a slope. The video vaginal speculum provided by the invention has the beneficial effects that for the connecting ring, the clamping gaps with appropriate lengths are respectively arranged at two ends of the clamp hook, the slope is arranged at the end part of one end of the clamping groove of the handle, so that the clamping connection between the connecting ring and the handle is reliable, the disassembly is convenient and fast, therefore, the disassembly for disinfection or the discarding after disposable use of the speculum lens is facilitated, and cross infection among patients can be avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a colposcope used for diagnosis and treatment of vaginal diseases. Background technique [0002] The function of the colposcope is to extend the upper and lower duckbills into the vagina through the hinged connection, and then open the vagina. The doctor can observe the condition of the internal vaginal lesions by visual or camera shooting. The handle of the vaginal speculum and the lower duckbill piece are usually connected as a whole, such as the invention patent of CN102525392B issued by the China Patent Office on August 21, 2013, and the publication number disclosed on February 20, 2013. It is an invention patent of CN102934984A and a utility model patent with the announcement number of CN205268137U authorized on June 1, 2016. The handle of the vaginal speculum described in these patents and the lower duckbill are all connected as one. As we all know, the upper and l...

Problems solved by technology

As we all know, the upper and lower duckbills of the colposcope are in direct contact with the patient's vagina and will inevitably be polluted. In order to prevent cross infection between patients, the upper and lower duckbills of the colposcope are It must go through strict immersion disinfection or solve it by one-time use. Obviously, the handle is connected with the lower duckbill piece, and the lower duckbill piece is hinged with the upper duckbill piece. To be sterilized, it must be connected with the handle. Disinfect together, and the handle is often equipped with components such as cameras and electronic control systems. These electronic components cannot be in contact with liquids. They must be dismantled before disinfection and reassembled after disinfection. Various procedures are very troublesome.

If a one-time use method is adopted, since these electronic components are expensive, they will be discarded together with the handle, which is very uneconomical and will bring unbearable high medical expenses to patients
