Abstract
The utility model relates to a push-in definite quantity type endoscope looping and ligating device, which comprises sheathing and binding rings, a catheter, a push rod, an outer tube, an inner tube, a tail sleeve, an annular piston, a water storage pipe, a water filling pipe and a water suction eyelet. The outer tube and the inner tube are fixed on the tail sleeve concentrically. The bottom in the concentric annular space formed by the outer tube and the inner tube is provided with an annular piston. A plurality of sheathing and binding rings are sheathed on the exterior surface of the inner tube in the concentric annular space in order, and one end of the catheter passes through the tail sleeve to be communicated with the bottom of the concentric annular space. The other end of the catheter is connected with the water outlet of the water filling pipe. The push rod is plugged in the water filling pipe, the outside of which is provided with the water storage pipe. The lower part of the water filling pipe near the water outlet is provided with the water suction eyelet communicated with the water storage pipe. The scheme solves the problem of eye-reach obstacle caused by a backing ring and quantitatively controls the liquid supply by arranging the water suction eyelet so that moving distances of the piston are identical, ensuring the continuous and accurate discharge of the sheathing and binding rings to carry out the treatment of a plurality of diseased regions.
Description
Technical field:
This utility model relates to a kind of medical device, particularly relates to a kind of quantitative pusher endoscope cover bundling device that is used with medical endoscope.
Background technology:
Endoscope cover bundling device is mounted in endoscope distal end in the prior art, by with being used of endoscope, can treat the cirso-disease at positions such as the intravital esophagus of people, the intestines and stomach.United States Patent (USP) " endoscope's looping and binding device ", the patent No. is 5624453, and the applying date is 1997.04.29, discloses a kind of looping and binding device, this looping and binding device breaks away from cover Zha Quan by pulled by cable one by one from the sleeve of endoscope's looping and binding device, cover is pricked the diseased region that snare is contained in needs treatment, disclosed this looping and binding device complex structure, cost height, in use, pulled by cable makes the body bending of endoscope, causes the position to move, and makes cover Zha Quan be difficult to accurate emission.Chinese patent " endoscope's cover bundling device " number of patent application is 200410000053.X, the applying date is 2004.01.06, the applicant discloses a kind of endoscope cover bundling device, being provided with gasket ring in the endoscope that applied for cover bundling device is overlapping the postoperative of pricking the hand and is falling in the esophagus of human body, hinder the visual field of endoscope, disturbed further surgical work.
Summary of the invention:
The purpose of this utility model provides a kind of quantitative pusher endoscope cover bundling device, to remedy the deficiencies in the prior art.
A kind of quantitative pusher endoscope cover bundling device that this utility model relates to, it includes cover Zha Quan, conduit, push rod, and it also includes outer tube, interior pipe, tail cover, annular piston, standpipe, water injection pipe, suction eye;
Described outer tube and interior pipe are fixed on tail with one heart and put, bottom in the concentric annular space of outer tube and interior pipe formation is provided with annular piston, described several covers Zha Quan is arranged in order on the inner tube outer surface that is sleeved in the concentric annular space, and an end of described conduit passes the tail cover and is connected with bottom, concentric annular space;
The other end of described conduit is connected with the outlet of water injection pipe, and push rod is inserted in the water injection pipe, is provided with standpipe in the water injection pipe outside, is provided with the suction eye that is connected with standpipe in the water injection pipe bottom near the outlet place.
When work, quantitative pusher endoscope cover bundling device is aimed at diseased region along with endoscope enters in patient's body, advance push rod, make unnecessary water return standpipe by suction eye, be pushed into the displacement of conduit drive annular piston and stay quantitative water, promote cover Zha Quan and outwards move release, launch out rapidly and be sleeved on therapentic part.
This utility model endoscope cover bundling device good effect is:
1. compared with prior art removed because endoscope's disturbance of visual field problem that gasket ring causes can be made further sclerotherapy simultaneously.
2. by the water injection pipe suction eye, can quantitatively control feed liquor quantity, the distance that piston is moved each time is identical, and the repeatedly stable cover of emission successively Zha Quan carries out the treatment of a plurality of diseased regions.
3. the outer tube smooth surface of endoscope's cover bundling device makes the patient when swallowing endoscope's cover bundling device, has avoided the problem of pharyngeal scratch and venous hemorrhage.
4. by present design, saved exhaust apparatus.
Quantitative pusher endoscope of the present utility model cover bundling device, the disposable product that all adopts plastic material to make, simple in structure, easy to operate, safe and reliable, cost is low, and is easy to utilize.
