Description

Technical Field

[0001] The utility model relates to the technical field of endoscopes, in particular to an endoscope forceps channel tube. Background Art

[0002] The clamp channel tube of the medical flexible endoscope is a major component of the endoscope among medical devices. It is a small and long open channel. The clamp channel tube of the endoscope enters the human body cavity to reach the lesion site, and performs biopsy sampling, removal of foreign bodies, polyps and other surgical operations on the tissues at the lesion site.

[0003] The existing endoscope forceps channel tubes on the market are generally divided into two main parts: an outer sleeve and an inner sleeve. When adjusting the overall length of the channel tube, the inner sleeve needs to be rotated and slid out from the end of the outer sleeve before the introduction operation is performed. After the channel tube enters the patient's body, the length cannot be adjusted again from the outside. For this reason, we propose an endoscope forceps channel tube. Utility Model Content

[0004] The utility model aims to provide an endoscope forceps channel tube to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0012] Preferably, a knob is fixedly connected to the outer side of the connection between the threaded rod and the push rod, and anti-slip diagonal lines are provided on the outer wall of the knob and the plug;

[0013] Preferably, the inner diameter of the end of the outer tube body away from the plug is smaller than the outer diameter of the guide ring.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. This kind of endoscope forceps channel tube is used in conjunction with an outer tube body, an inner tube body, a threaded rod, a push plate and a plug. The knob drives the push rod to rotate. When the push rod rotates, it drives the threaded rod to rotate around the plug and the threaded groove in the middle of the threaded head and penetrate into the outer tube body. Then, the push plate at the end of the threaded rod pushes the inner tube body forward, so that the inner tube body is pushed out from the end of the outer tube body again, so that it is convenient to adjust during the operation.

[0016] 2. This kind of endoscope forceps channel tube is used in conjunction with an outer tube body, an inner tube body, a spring and a guide ring. When the operation is completed, the knob is reversed to make the push plate retract. At this time, the spring compressed by the guide ring will rebound and reset, thereby driving the inner tube body to be quickly retracted into the outer tube body, so that the inner tube body can be retracted faster.
