Description

Disposable hemorrhoid looping and binding device

Technical field

This utility model belongs to a kind of medical apparatus and instruments, is specifically related to be used for the treatment of the looping and binding device tool of hemorrhoid.

Background technology

Hemorrhoid looping and binding device in the past,, is made because of metal material by being responsible for the operation principle of negative-pressure adsorption with rifle formula mechanical form with the metal material manufacturing, and its shortcoming is:

1, it is poor that permeability is responsible in absorption, is responsible for suction what are organized, and with operator's feel, finishes the cover bundle because of not looking at straight down, so the property of following blindly, uncertainty are arranged entirely.

2, rifle formula looping and binding device metal material is made, complex process manufacturing cost height.

3, rifle formula machinery is complicated, and inconvenience is cleaned, sterilization.

Summary of the invention

The purpose of this utility model is that a kind of permeability of design is good, easy to operate through the disposable hemorrhoid looping and binding device of disinfectant, its technical scheme includes: draw ring conehead, pushing ram, slide lid, main suction pipe and piston, main suction pipe is transparent plastic tube, in the leading section truncation opening, main suction pipe is piston.Main suction pipe and piston type are like plastic injector for temporary use, and just the leading section truncation with needle tubing forms opening.The outside of main suction pipe is with slide lid, and the front of slide lid is provided with pushing ram.Be placed with on the opening of main suction pipe front end and draw the ring conehead, draw the ring conehead and merge into taper, tapering part is split up into petal-shaped.

Slide lid be shaped as cylinder, or be arc-like sheet cylindraceous, arc-like sheet can partly wrap retaining ring on main suction pipe.

Two side bus of main suction pipe are provided with the rib of projection, and pushing ram is provided with groove, and the rib on the main suction pipe matches with groove on the pushing ram.

During doctor's operation technique, cushion rubber is inserted in draws ring conehead front end, draw ring conehead likeness in form alabastrum, separately petal moves down cushion rubber and is enclosed within on the main suction pipe, the adsorbate of the tight-lipped closely connected nearly patient's affected part of main suction pipe, pulling piston master suction pipe forms negative pressure, soft material enters in the main suction pipe tube chamber, main suction pipe manufactured materials lucite pipe, adsorbate can be high-visible, promotes slide lid forward, pushing ram is just released cushion rubber main suction pipe mouth, cushion rubber is with the soft material ligation of affected part, and the soft material of affected part comes off naturally after several days, and hemorrhoid just can be cured.

The utlity model has following effect:

1, its operation principle negative-pressure adsorption is consistent with rifle formula looping and binding device, main suction pipe manufactured materials lucite pipe, and adsorbate can be high-visible, increased the accuracy of getting the pipe thing, avoids the blindness ligation as far as possible.

2, main suction pipe and pitch brace technology maturation, the suction pipe negative pressure is big, and absorption affinity is strong, can satisfy the absorption of all kinds of hemorrhoid.

3, disposable tubulose looping and binding device, material and production technology are simple relatively, and be cheap, once uses and avoid cross infection.

This apparatus production cost is cheap relatively, and processing technology is simple, and is economical and practical, main suction pipe technical maturity, and absorption affinity is strong, safety, reliable.

Fig. 1 is a front view of the present utility model, shows its population structure, and front end is inserted in cushion rubber;

Fig. 2 is with the front end petal among Fig. 1 separately, with the state diagram of cushion rubber introducing;

To be this utility model be incorporated into state diagram on the main suction pipe with cushion rubber to Fig. 3, taken off and drawn the ring conehead;

Fig. 4 is the state diagram that Fig. 3 piston is pulled out.

The specific embodiment

Now in conjunction with the accompanying drawings, concrete structure of the present utility model is described below.As shown in Figure 1, this utility model includes: draw ring conehead 2, pushing ram 3, slide lid 4, main suction pipe 5 and piston 6, draw the front end that encircles conehead 2 and be inserted in cushion rubber 1, draw ring conehead 2 likeness in form alabastrums, it during merging taper, be split up into petal, drawing ring conehead 2 is sitting on the truncation opening of main suction pipe 5, cooperate with piston 6 in the main suction pipe 5, the outside of main suction pipe 5 is with slide lid 4, and slide lid 4 is the large semicircle barrel shape, and slide lid 4 cooperates with main suction pipe 5 retaining rings, slide lid 4 front ends have pushing ram 3, and pushing ram 3 is distributed in the left and right sides of main suction pipe 5.

Claims (3)

1, disposable hemorrhoid looping and binding device, include: draw ring conehead (2), pushing ram (3), slide lid (4), main suction pipe (5) and piston (6), it is characterized in that main suction pipe (5) is transparent plastic tube, leading section truncation opening, in the main suction pipe (5) is piston (6), the outside of main suction pipe (5) is with slide lid (4), the front of slide lid (4) is provided with pushing ram (3), on the opening of main suction pipe (5) front end, be placed with and draw ring conehead (2), draw ring conehead (2) and merge into taper, tapering part is split up into petal-shaped.
