The technical proposal of the utility model is that,

the utility model provides a cover is inhaled to medical transparent mucosa in no water conservancy diversion hole, including inhaling the cover body, it includes cylindrical barrel to inhale the cover body, cylindrical barrel includes the front end that connects gradually along the axial, protruding muscle and rear end joint portion, the front end is provided with two ring channels, two ring channels set up respectively in the inner wall both sides that protruding muscle one end was kept away from to the front end, the rear end joint portion is connected with the slope joint portion in the one end of keeping away from protruding muscle, slope joint portion and cylindrical barrel integrated into one piece, the slope joint portion is used for connecting the endoscope.

The utility model is also characterized in that,

the front end, the convex rib and the rear end combining part are integrally formed, and the convex rib is a radial outward convex ring along the cylindrical barrel.

The axial dimension of the front end is smaller than that of the rear end combining part, and the axial dimension of the convex rib is smaller than that of the front end.

The radial dimension of the ramp junction at the end remote from the cylindrical barrel is less than the radial dimension of the cylindrical barrel.

The combination part of the slope combination part and the cylindrical barrel is an arc surface.

The suction sleeve body is made of thermoplastic polyurethane elastomer rubber.

The utility model has the advantages that the side diversion hole is cancelled in the medical transparent mucosa suction sleeve without the diversion hole; compare the medical transparent mucosa of traditional area water conservancy diversion hole and inhale the cover and increased the function of attracting fixed tissue, increase the negative pressure and attract the function, realize fixed target tissue, the fixed point is become more meticulous to be operated, reduces the operation time, reduces the operation degree of difficulty and risk to a certain extent.

Drawings

Fig. 1 is a schematic structural view of the medical transparent mucosa suction sleeve without the diversion hole of the utility model.

In the figure, 1 is a front end, 2 is a convex rib, 3 is a rear end combining part, 4 is a slope combining part, and 5 is an annular groove.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, a medical transparent mucosa suction sleeve without diversion holes comprises a suction sleeve body, wherein the suction sleeve body comprises a cylindrical barrel body, the cylindrical barrel body comprises a front end 1, a convex rib 2 and a rear end combining part 3 which are sequentially connected along the axial direction, the front end 1 is provided with two annular grooves 5, the two annular grooves 5 are respectively arranged on two sides of the inner wall of the front end 1 far away from one end of the convex rib 2, the rear end combining part 3 is connected with a slope combining part 4 at one end far away from the convex rib 2, the slope combining part 4 and the cylindrical barrel body are integrally formed, and the slope combining part 4 is used for connecting an endoscope.

And the annular groove 5 is used for placing a ferrule of the snare, the ferrule is a commonly used matching part of the endoscope, and under the suction of the endoscope, lesion tissues are sucked into the transparent cap, and the snare is tightened for snaring. The design is convenient for the snaring of the snare without falling off, and the snaring success rate is improved to a greater extent.

The specific operation is as follows: the loop rope is softer, the loop rope is not easy to loop and prick during operation, and after the tissue of the loop and prick is sucked, the loop rope is pulled lightly, the loop rope falls off, and the tissue can be just sleeved.

Further, front end 1, protruding muscle 2 and rear end joint portion 3 integrated into one piece, protruding muscle 2 is along the radial outside protruding circle of cylindrical barrel.

The utility model relates to a medical transparent mucosa of no water conservancy diversion hole inhales cover's leakproofness is stronger, can inhale the cover inner chamber with the tissue better, realizes the ligation function.

Further, the axial dimension of the front end 1 is smaller than the axial dimension of the rear end engaging portion 3, and the axial dimension of the rib 2 is smaller than the axial dimension of the front end 1.

Further, the radial dimension of the ramp junction 4 at the end remote from the cylindrical barrel is smaller than the radial dimension of the cylindrical barrel.

Further, the combination part of the slope combination part 4 and the cylindrical barrel is an arc surface.

Furthermore, the suction sleeve body is made of thermoplastic polyurethane elastomer rubber.

The utility model relates to a medical transparent mucosa of no water conservancy diversion hole inhales cover adopts soft texture, the TPU that biocompatibility is good to mould plastics elastically and forms, reduces the stimulation to the mucous membrane tissue in the use, reduces the patient discomfort and stops to scrape broken mucous membrane and the risk of infecting is simple and easy, and the success rate is high, once can cut totally to less flat type pathological change, and the tumour is particularly suitable for under the small-size mucosa, need not special equipment.

The side surface of the medical transparent mucosa suction sleeve without the flow guide hole of the utility model cancels the flow guide hole, increases the negative pressure suction adsorption function, can fix the target tissue in the operation process, and simultaneously plays the role of drawing close and amplifying; the fine operation of the target tissue is realized, the function of attracting and fixing the tissue is increased, and the operation difficulty and risk are reduced to a certain extent.

The utility model relates to a medical transparent mucosa suction sleeve without a diversion hole, which is suitable for an electronic gastrointestinal endoscope with a tip part between 9 mm and 15 mm. The multifunctional endoscope is used for digestive endoscopy ESD, EMR, POEM, STER and other operations, and provides continuous and clear vision and working space for endoscopic observation and endoscopic treatment. The fixed tissue is lifted or sucked in an auxiliary way in the surgical excision, so that the refinement of the surgical operation is realized; the surface is smooth, the elasticity is moderate, and the soft material avoids the scratch of the hard endoscope front end part to the tissue.

The utility model relates to a medical transparent mucosa of no water conservancy diversion hole inhales cover has cancelled the water conservancy diversion hole of side, through increasing the negative pressure suction adsorption function, reaches the function that increases the fixed tissue of attraction, reduces the operation degree of difficulty and risk to a certain extent, has certain practicality.
