Protective sleeve, hysteroscope with protective sleeve, and nephroscope with protective sleeve

Abstract

The invention provides a protective sleeve, a hysteroscopy with a protective sleeve, and a nephroscope with a protective sleeve, which are used for preventing an electric connection line connected with an endoscope from being polluted by filth and include an internal sleeve and an outer sleeve which are connected with each other in sleeve, wherein the outer sleeve is a tube structure, and the internal sleeve comprises a vertical tube portion and a bellmouth portion; the bellmouth portion is located on an insert end side of the internal sleeve, a side wall of the bellmouth portion is provided with a plurality of grooves extending from the bellmouth portion to the vertical tube portion, and a plurality of flexure strips are formed on the insert end of the internal sleeve. Connection portionscapable of matching with a self-lock quick joint are formed in inner walls of the flexure strips. A cavity is installed between the internal sleeve and the outer sleeve and is provided with a compressed water-proof sleeve, wherein one end of the water-proof sleeve is fixedly connected in the internal sleeve in sleeve, and the other end of the water-proof sleeve can be pulled out from a non-insertend of the protective sleeve. The protective sleeve has the advantages that weight is light, volume is small, operation is easy, the electric connection line is effectively prevented from being polluted in the using process, situation including short circuit and pollution are prevented, production cost is low, and can be used as disposable medical device.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a protective sheath, a hysteroscope with the protective sheath and a method for using the protective sheath. Background technique [0002] Endoscope is a kind of light source endoscope mainly used for inspection and treatment inside the human body. It uses the front part of the mirror body to enter the inside of the human body. However, in the prior art, when inspecting the inside of the patient's body, it is usually necessary to extend the endoscope from the patient's body first, enter the inside of the human body, and observe the patient. To perform treatment, or keep the endoscope in the patient's body, insert the treatment instrument into the patient's body at the same time, and treat the patient. Because in the process of diagnosis and treatment, it is usually necessary to inject physiological saline into the patient's body to distend the uterus, the fluid in the patient'...

AI Technical Summary

Problems solved by technology

[0007] The operation of this type of endoscope is relatively complicated in actual use, and it can only prevent the liquid in the patient from flowing out to a certain extent, and its safety and reliability are low.

[0008] In the prior art using the above-mentioned endoscope as an example, the electrical connection wires will inevitably be polluted by the dirt flowing out of the patient's body, which is not only prone to dangers such as short circuits, causing damage to electrical appliances, but also easily polluting users. In addition, since the electrical connecting wires are not easy to be sterilized, secondary pollution is prone to occur
