Operating device for expanding cavity body

Abstract

The invention relates to an operating device for expanding a cavity body. The operating device is used for completing an expansion operation before an operation of a narrow cavity body, and belongs to the field of medical operation apparatuses. The device comprises a hollow outer tube (2), an inner tube (3), an expanding nozzle (1) and a turning handle (4), wherein the inner tube (3) is positioned in the outer tube (2); the expanding nozzle (1) is positioned at the front end of the outer tube (1) and is connected with the outer tube (1); the turning handle (4) is positioned at the back end of the outer tube (2) and is connected with the outer tube (2); the expanding nozzle (1) comprises an upper expanding nozzle (1a), a lower expanding nozzle (1b) connected with the upper expanding nozzle (1a) and a connection part (1c) for connecting the upper expanding nozzle (1a) and the lower expanding nozzle (1b) to the outer tube (2); a cross bar (1-2) is arranged on the inner surface of the lower expanding nozzle (1b); and a rotation pair is arranged on the connection part (1c). The operating device has the advantages that the expanding process is conveniently adjusted, and the implantation and the operation of the operation apparatuses are not hindered during the expansion.

Description

technical field [0001] The invention belongs to the field of medical operation instruments, in particular to an operation expansion instrument, which can be used for the expansion operation of a closed cavity before operation. Background technique [0002] There are multiple cavities inside the human body, most of which are naturally open cavities, such as esophagus and nasal passages, which can be directly implanted with surgical instruments for operation during surgery. However, there are also some natural airtight lumens. If these lumens have lesions and require surgery, artificial expansion methods must be used to expand the lumens. The more typical closed cavity is the female uterine cavity. [0003] Uterine dilatation technology is widely used in gynecological surgery and intrauterine examination. Its fundamental function is to expand the closed uterine cavity to form a visual environment and an operating environment. The methods of uterine distension currently used ...

AI Technical Summary

Problems solved by technology

Although liquid uterine distension is widely used at present, it is mostly used in hysteroscopic pathological examination, but it cannot be applied in abortion

The reasons are as follows: firstly, when the intrauterine cavity is injected with liquid and curettage is performed, the bleeding in the intrauterine cavity is easy to spread and dissolve in the medium liquid, resulting in discoloration of the liquid, which affects the operation observation and operation; secondly, during negative pressure suction, there is A large amount of fluid interferes internally, and it is likely that the target gestational sac tissue cannot be successfully sucked out, resulting in an inability to successfully complete the operation
