Description

First end cap of digestive endoscope Technical Field The invention relates to the technical field of end caps, in particular to an end cap of a digestive endoscope. Background With the progress of medical science and technology and the update iteration in the aspect of checking instruments, doctors have more methods for operation and treatment checking, and a plurality of limitations exist in the scene of current digestive endoscope application, the prior digestive endoscope generally needs to be sleeved with a front end cap at the top of the endoscope when in use, so as to provide a larger endoscope viewing field for the endoscope, the lens can not be closely attached to viscera to cause the condition of incapability of viewing, and the front end cap is generally directly wrapped and fixed on the outer surface of the endoscope when in installation and fixation, so that the front end cap is quite easy to drop due to the use of auxiliary instruments or due to bending of the endoscope, peristaltic movement of the intestinal canal and the like when in use, the front end cap is quite easy to drop when in use of auxiliary inserted instruments when in use of the multichannel endoscope, the instruments can not normally deviate from a preset path when in use of the auxiliary instruments, the operation accuracy is affected, the risk of damage of digestive tract mucous membrane can also be increased, and the requirements of clinical accuracy, safety and the front end cap drop of the digestive endoscope can not be met, and the endoscope is quite easy to use. SUMMARY OF THE PATENT FOR INVENTION The present invention provides a tip cap for a digestive endoscope, which solves the problems that the tip cap is easy to drop and cannot guide an instrument in the prior art. In order to achieve the above purpose, the invention provides the technical scheme that the tip cap of the digestive endoscope comprises an endoscope lens, wherein one side of the endoscope lens is fixedly provided with an auxiliary tube, surgical instruments are arranged in the auxiliary tube in a penetrating manner, the height of the auxiliary tube is lower than that of the endoscope lens, an inner sleeve is inserted and installed on the outer surface of the endoscope lens, anti-slip tooth points are uniformly arranged in the inner sleeve, the outer surface of the anti-slip tooth points is contacted with the endoscope lens, the outer surface of the endoscope lens is attached to the inner surface of the inner sleeve, an outer soft end cap is inserted and installed on the outer portion of the inner sleeve, and a buckle extrusion mechanism is arranged between the outer soft end cap and the inner sleeve. Preferably, the buckle extrusion mechanism comprises an inner plastic sleeve, wherein the inner plastic sleeve is fixedly embedded on the inner side of an outer soft end cap, the outer soft end cap is a hollow columnar body made of flexible materials, one end of the inner sleeve is of an inclined design, the outer surface of the inner sleeve is tightly attached to the outer surface of the inner plastic sleeve, positioning teeth are uniformly arranged at one end, close to the auxiliary pipe, of the inner sleeve, and the positioning teeth are clamped with the inner plastic sleeve. By adopting the technical scheme, the inner plastic sleeve and the inner sleeve are inserted, so that the inclined surface of the inner sleeve can be effectively deformed, the anti-slip tooth points can be further inserted into the endoscope head, the positioning teeth can be clamped with the inner plastic sleeve, the strength of the inner sleeve on the endoscope head is further enhanced, the deformation of the inner sleeve and the inner plastic sleeve can be effectively reduced due to the use and the material characteristics of the inner sleeve and the inner plastic sleeve, and the falling probability of the outer soft end cap in use is reduced. Preferably, the vent hole is formed in one end, far away from the inner plastic sleeve, of the outer soft end cap, the vent hole is not attached to the outer surface of the inner plastic sleeve, and an inclined surface is formed in one end, far away from the positioning teeth, of the outer soft end cap. By adopting the technical scheme, when the outer soft end caps can be effectively attached to the inner wall of the viscera through the vent holes, pressure relief can be carried out, negative pressure can not be generated between the outer soft end caps and the outer surface of the viscera to cause adsorption, meanwhile, the flatness between the outer soft end caps can be further reduced through the use of the inclined planes, one ends of the outer soft end caps can form gaps, and the firmness of adsorption can be reduced when the outer soft end caps move. Preferably, the outer soft end cap is close to one side external surface fixed of accessory tube and has seted up the side hose, and the side hose is hollow design to the one end of side h
