Split electronic video endoscope

Abstract

The invention discloses a split electronic video endoscope which comprises an operation handle, a body pipeline and an endoscope body, wherein the front end of the body pipeline is connected with the endoscope body, and an interface part is arranged at the rear end and inserted with the front end of the operation handle; a guide channel is arranged on the pipe wall of the body pipeline and communicated with the front part and rear part of the body pipeline; a traction guide wire is arranged in the guide channel; the traction guide wire has certain toughness; one end of the traction guide wire is connected with the front part of the body pipeline, and the other end is connected with the rear part of the body pipeline; and annular slots are formed in the outer walls of the front part and rear part of the body pipeline. With a snake neck linkage structure, the split electronic video endoscope disclosed by the invention can realize a function of bending the rear part of the body pipeline to drive the front part of the body pipeline to synchronously turn into an arc; and due to a split structure, temporary pipe replacement caused by matching during operation can be finished without completely taking out the body pipeline and the endoscope body again.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a split type electronic video endoscope. Background technique [0002] Endoscope is suitable for observing the tissue structure and lesions in the cavity, biopsy sampling, etc. At present, clinical intubation endoscopes have the following disadvantages: 1. High price, complex structure and easy damage, high maintenance cost; 2. High-value equipment, limited purchase quantity, no multiple rotation backup, repeated use, Cleaning and disinfection is cumbersome and time-consuming, and there is a risk of cross-infection; 3. The bulk is bulky, and it is easy to fatigue when suspended for a long time, and it is easy to be broken and damaged; 4. It is not specially designed for anesthesia tracheal intubation. 5. The function is single, only to realize the guiding effect of intubation; 6. The arc-changing motion of the front part of the scope tube is realized through the operating hand...

At present, clinical intubation endoscopes have the following disadvantages: 1. Expensive, complex and easily damaged structure, and high maintenance costs; 2. High-value equipment, limited purchase quantity, no multiple backups in rotation, repeated use, It is cumbersome and time-consuming to clean and disinfect, and there is a risk of cross-infection; 3. It is bulky, and it is prone to fatigue and damage when suspended for a long time; 4. It is not specially designed for anesthesia tracheal intubation, and it needs to be cannulated in advance, and it cannot be changed midway; 5. The function is single, only to realize the guiding function of intubation; 6. The arc-changing movement of the front part of the scope tube is realized through the operating handle, and the operating handle is bulky and the internal structure is complicated
