Detailed Description

In order that the utility model may be readily understood, a more complete description of the utility model will be rendered by reference to the appended drawings. Several embodiments of the utility model are presented in the figures. This utility model may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "mounted" on another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 5, the air bag fixing device for enteroscope of the present utility model includes a sleeve 10, an air bag 20 and an inflatable structure 30, wherein the sleeve 10 includes an insertion portion 11, a body portion 12 and a plurality of connection posts 13, the insertion portion 11 is fixedly disposed at one end of the body portion 12 through the connection posts 13, the plurality of connection posts 13 are disposed in a ring-shaped array with a center of the sleeve 10 as a center point, a gap is formed between two adjacent connection posts 13, the air bag 20 is disposed in the gap, and the inflatable structure 30 is used for inflating or deflating the air bag 20.

In this embodiment, a plurality of concave structures 41 are disposed on the outer wall of the body 12 at intervals. It will be appreciated that providing the concave structure 41 on the outer tube wall of the body 12 reduces the contact area between the body 12 and the intestine, thereby reducing the friction of the cannula 10 during insertion and alleviating pain in the patient.

Further, the end of the insertion portion 11 away from the body portion 12 is provided with a rounded structure 42, and it will be appreciated that the rounded head end can prevent the sleeve 10 from scratching the intestinal tract of the patient during the insertion process, thereby reducing the risk of surgery.

Specifically, the inflation structure 30 includes an inflation tube 31, a communication tube 32 and an inflation valve (not shown), the plurality of airbags 20 are mutually communicated through the communication tube 32, an air tube guiding slot 33 is concavely formed on the inner tube wall of the body portion 12, the air tube guiding slot 33 is penetratingly arranged along the axial direction of the body portion 12, the inflation tube 31 is arranged in the air tube guiding slot 33, one end of the inflation tube 31 is communicated with one of the plurality of airbags 20, and the other end is communicated with the inflation valve. In this embodiment, the inflation valve is specifically an injector that is in communication with the inflation tube 31, and inflation or deflation of the airbag 20 is achieved by pushing and pulling a piston rod of the injector. In addition, in the present embodiment, the inflation tube 31 is embedded in the air tube guiding slot 33 on the inner tube wall of the main body 12, rather than being led out from the outside of the main body 12, so that discomfort of the patient caused by contact between the inflation tube 31 and the inner wall of the intestinal tract can be avoided.

Further, two opposite limiting flanges 34 are formed in the air pipe guiding clamping groove 33. The spacing distance between two limit baffles is less than the diameter of the air tube 31, in practical application, because the air tube 31 is made of flexible rubber materials and is deformable, an operator can press the air tube 31 into the air tube guiding clamping groove 33 from between the two limit baffles 34, and after the air tube 31 is pressed into the clamping groove and the shape is restored, the air tube 31 is difficult to separate from the air tube guiding clamping groove 33, so that the fixing effect of the air tube 31 is improved.

Further, a limit structure is disposed at one end of the body 12 away from the insertion portion 11, and the limit structure includes a limit clip ring 51 fixedly disposed on the body 12, and a limit stop piece 52 detachably connected with the limit clip ring 51. Specifically, in this embodiment, 4 screw holes are disposed at intervals on the peripheral side of the body 12, mounting holes corresponding to the screw holes are disposed on the limiting baffle plates 52, and screws penetrate through the mounting holes to be connected with the screw holes, so that assembly between the limiting baffle plates 52 and the body 12 is achieved, and the limiting snap ring 51 is used for positioning the mounting positions of the limiting baffle plates 52. It will be appreciated that a limit stop 52 is provided at the end of the body portion 12 to limit the depth of insertion of the cannula 10.

Further, a grip 53 is provided on one side of the limit stop 52 to facilitate the medical staff to grasp and remove the entire sleeve 10 from the anus.

Further, the surface of the balloon 20 facing the inside of the sleeve 10 is provided with a friction layer. In this embodiment, the friction layer is made of a rubber material specifically, so as to increase the friction between the air bag 20 and the mirror body, and improve the fixing effect.

In summary, according to the air bag fixing device for enteroscope in the above embodiment of the present utility model, the sleeve 10 is inserted into the anus of the human body, the scope body of the enteroscope passes through the inner hole of the sleeve 10 and enters the intestinal tract of the human body, and when the scope body of the enteroscope needs to be fixed, the air bag 20 at the end of the sleeve 10 is inflated to be tightly attached to the outer wall of the scope body, so that the scope body cannot slide relative to the sleeve 10, thereby releasing the hands of the medical staff, and solving the technical problems that the scope body in the prior art needs to be fixed by hand, and displacement occurs once the scope body is separated from the hand.
