Description

Split low-resistance and expansion small intestine mirror and assembly method thereof

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a split low-resistance and expansion enteroscope and an assembly method thereof.

Background

The small intestine endoscope is an endoscope examination, can find lesions in the small intestine of a patient, and has good diagnostic value on small intestine diseases. The imported double-air-bag small intestine endoscope adopted clinically at present mainly comprises a main scope, a main machine, a display and accessory equipment.

The front end of the main lens is provided with an air hole for connecting the air bag, the air bag is inflated and deflated, the length of the main lens is 2000mm, the outer diameter of the lens body is 8.5mm, the biopsy channel is 2.2mm, the outer diameter of the outer sleeve is 12.2mm, the front end of the main lens and the front section of the outer sleeve are respectively provided with the air bag, the near end of the front section of the outer sleeve is covered with a metal ring so as to be capable of identifying the approximate position under X rays, the near end of the outer sleeve is provided with two catheter connecting ends, one connecting the air pump and the outer sleeve air bag to inflate and deflate the outer sleeve is implemented, the other connecting end is led into the cavity of the outer sleeve and is used for injecting water to improve the lubricity between the outer sleeve and the endoscope, the air bag is made of latex, the thickness is about 0.1mm, and the main lens air bag is provided with a special device, and two ends of the air bag are fixed by rubber rings.

Double-air-bag small intestine endoscope working principle: the double-air-bag small intestine endoscope adopts a positive pressure and alternative working principle.

The specific working steps are as follows: when the double-balloon electronic small intestine endoscope just begins to work, the front balloon and the rear balloon are not inflated, the endoscope is firstly inflated from the oral cavity along the stomach and the duodenum, the balloons at the body part are inflated after passing through the duodenum by 20-30 cm, the small intestine is relatively fixed, then the auxiliary sleeve is pushed along the endoscope for about 50cm, the balloons of the auxiliary sleeve are inflated and kept in place, the gas of the balloon at the front end part of the endoscope body is pumped out and pushed forward, the balloon at the front end part is inflated, the sleeve of the endoscope is pushed forward, the relative operation is carried out, and the small intestine is continuously sleeved on the outer sleeve of the double-balloon endoscope by combining the skills of hooking and the like when necessary. Meanwhile, the treatment such as biopsy, mucosa marking, polypectomy and the like can be performed according to actual conditions. The full intestinal examination is completed by oral joint and anus two-way butt joint.

Currently, the above devices have the following drawbacks:

1. because the relative operations of inflation, propulsion and deflation are required to be continuously carried out according to the above process during the examination, and meanwhile, the space yield of the design structure of the small intestine mirror (the space yield is that the small intestine content volume is subtracted by the difference value of the volume occupied by the small intestine mirror, the small intestine content volume is a constant value, the larger the small intestine mirror and the auxiliary structure occupy, the smaller the space left in the small intestine is, the smaller the space for overlapping the intestinal canal is), the small intestine overlapping effect is poor as shown by the shadow part area in the figure 1, the small intestine is easy to slip during the operation, and the small intestine can be continuously sleeved on the outer sleeve of the double-air-bag endoscope by combining the skills of hooking and the like when necessary, so that the detection time is long:

2. the traditional small intestine mirror has only a single operation channel and cannot carry out complex operation: for example, collection of the specimen while cutting the specimen, or simultaneous clotting or pipetting when bleeding;

3. the prior endoscope imaging module is solidified at the front end and disinfected together with the whole endoscope, so that leakage and non-imaging are easy to occur, and the inspection process and efficiency are affected;

4. the examination is not tolerated by patients because the examination requires a complete intestinal examination by oral and anal bi-directional docking.
