Abstract

The invention relates to the technical field of medical equipment, and discloses a pipe orifice reducing control structure which comprises an adjusting belt (20), an adjusting piece and an outer sleeve (30), the first end of the outer sleeve (30) can be connected to the front end of an endoscope (40), a supporting ring is defined by the adjusting belt (20) and supported on the inner circumference of the outer sleeve (30), and the adjusting piece is connected with the adjusting belt (20). The adjusting piece can adjust the diameter of the adjusting belt (20) so as to change the caliber of the second end of the outer sleeve (30). According to the technical scheme, the supporting ring defined by the adjusting belt is utilized and can be attached to the outer sleeve, the diameter of the adjusting belt can be changed under adjustment of the adjusting piece, then the caliber of the outer sleeve is changed accordingly, the diameter of the end opening of the control structure with the variable pipe opening diameter can be adjusted according to needs, and therefore the requirement in an operation is met; the pipe orifice reducing control structure does not need to be replaced, the operation cost is reduced, the operation is facilitated, and the operation progress is shortened.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a control structure for reducing the diameter of a nozzle. Background technique [0002] "Transparent cap", that is, medical transparent mucosal suction sleeve, belongs to the second class of medical devices. It was first used in Japan in 1992 to assist endoscopic mucosal dissection. Installing a transparent cap on the front end of the digestive endoscope lens can not only help the lens to be fixed and the isolation between the lens and the tissue, thereby improving the clarity of the endoscopic view, but also attract the lesion during the operation, so that the lesion that enters the transparent cap is convenient The snare is further ensnared and removed by high-frequency electrocautery. This new technology is especially suitable for flat lesions. With the help of the transparent cap, the lesions can be absorbed into a drop shape, which effectively reduces the difficu...
