Technical Field

The invention relates to the field of medical auxiliary related products, in particular to a gastroscope outer sleeve for treatment.

Background

At present, the method for taking out the sharp foreign matters (such as fishbone, chicken bone, hair clip, jujube pit and the like) in the upper digestive tract (esophagus and stomach) is that after a simple gastroscope enters the esophagus or reaches the stomach, the tool is sent to the esophagus or the stomach through a gastroscope biopsy pore canal by a foreign matter clamp or a snare, a basket and other tools in vitro, and the foreign matters are clamped or sleeved and taken out together with the gastroscope. However, the prior art has certain defects:

1. because the sharpness of sharp foreign matter, the in-process angle of taking out is difficult to control, and the esophagus chamber is narrower relatively simultaneously, and the esophagus chamber possesses three physiological narrowings simultaneously, passes through the in-process of esophagus at the foreign matter very easily with the esophagus wall damage, the esophagus hemorrhage appears or perforates probably.

2. No matter which tool is adopted to take the foreign matter, the foreign matter falls off due to physiological stricture of the esophagus and other reasons in the process of passing through the esophagus, incarceration is caused in the esophagus, and secondary injury of the esophagus is caused.

3. When the foreign body is taken, the sharp foreign body needs to be propped against the front end of the gastroscope, so the foreign body can easily damage the front end of the gastroscope.

Disclosure of Invention

The present invention is directed to a gastroscope overtube for treatment to solve the problems set forth in the background art.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a gastroscope outer tube is used in treatment, includes the outer tube body, the outer tube body divide into front end and tail end, one side that the outer tube body is close to the tail end is equipped with the external tapping that is linked together, the cover is equipped with solid fixed ring on the tail end, gu be equipped with the joint on the fixed ring, fixedly connected with latch segment, two on the inner wall of joint all be equipped with the latch notch on the latch segment, two be equipped with the check lock lever between the check lock lever, the check lock lever is inserted and is established in the latch notch, the tail end is loudspeaker form setting.

Preferably, two be equipped with the screw socket of opposite setting on the latch segment, be equipped with the external screw thread on the check lock lever, be threaded connection between check lock lever and two latch segments.

Preferably, one end of the locking rod is fixedly connected with a rotating block.
