Description
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 disposable ligation instrument of hemorrhoid.
Background technology
The applicant has applied for that on August 18th, 2008 name is called disposable haemorrhoids ligation apparatus, and the patent No. is CN200820188725.8, and publication number is CN201239174, in patented certificate on May 20th, 2009.The content of this patent includes: draw ring conehead, pushing ram, slide lid, main suction pipe and piston, main suction pipe is transparent plastic tube, is piston in the leading section truncation opening, main suction pipe.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 outer surface cover of main suction pipe has slide lid, and the front of slide lid is provided with pushing ram.Be placed with at 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.
The applicant applied for utility model patent on the 15th in December in 2010 again, name is called: disposable hemorrhoid ligation instrument, the patent No. is: CN2010206613637, the main improvement of its technical scheme and last patent is in the design of cushion rubber guiding: be placed with at the opening of main suction pipe front end and draw the ring conehead, drawing the ring conehead anterior is cone, afterbody is for drawing the ring tapered plug, draw the ring tapered plug and insert main suction pipe front end, draw the end that there is the pressed on ring drag wire in the afterbody system that encircles conehead, the other end of pressed on ring drag wire is enclosed within on the earrings of pushing ram outer wall.The pressed on ring drag wire is three, is evenly distributed.
Through clinical practice, find that three pressed on ring drag wires can not be synchronous in introducing the cushion rubber process, introduce cushion rubber and also have problems.
The cushion rubber of domestic and international disposable haemorrhoids ligation apparatus is to be preset at main suction pipe front end at factory's enforcement cushion rubber installation, cushion rubber mostly, such as Guangzhou Zhong Shan doctor automatic ligation device of hemorrhoids, the multi-ring haemorrhoids ligation apparatus in the Cook of the U.S., all be that cushion rubber has preset installation when the looping and binding device product export, it is that the doctor need not go up cushion rubber in use that such product has a benefit.Behind the product export, when product uses patient is uncertain.Cushion rubber is expansion state.Cushion rubber is preserved under expansion tractive state, easily oxidation, aging, and cushion rubber elastical retraction power descends year by year, and the general producer of these products requires, product uses after producing in two years.Quality just guarantee.Cushion rubber is the critical component of looping and binding device, and the quality of cushion rubber quality determines the success or failure of looping and binding device result of use and cover bundle technology.The no realization expection of cushion rubber quality decision cover bundle hemorrhoid physical ability comes off and plays a decisive role.
Producer is in order to prolong the quality expiry date of product both at home and abroad, high-quality cushion rubber oxidation resistance is constantly adopted in the design of cushion rubber product, improve the retraction elasticity of cushion rubber, prolong the looping and binding device life-span, this has brought again another problem, the elastical retraction power of cushion rubber strengthens, so that quilt cover is pricked hemorrhoid body early fallout.Be difficult to realize expecting the target that comes off.Because pricked quality, elastical retraction power and the specification of come off time limit and the cushion rubber of hemorrhoid body much relations are arranged.That is to say that elastic force is larger, cushion rubber is narrower, is pricked the hemorrhoid body to come off more early, and the cushion rubber that meets the specification of quality is the key for the treatment of.
Summary of the invention
The purpose of this utility model is the further improvement to above-mentioned patent, uses to reach clinical operation.
This utility model includes: piston, main suction pipe, cushion rubber propulsion tube, cushion rubber guide cone, cushion rubber dispensing seat and cushion rubber.Main suction pipe is transparent plastic tube, leading section truncation opening, and piston is in main suction pipe, the outer surface cover of main suction pipe has the cushion rubber propulsion tube, the cushion rubber propulsion tube is shorter than main suction pipe, and the cushion rubber guide cone plugs each other with cushion rubber dispensing seat and cooperates, and dispensing cushion rubber cover is enclosed within the front end of main suction pipe.
The outside backrush in tail end edge of main suction pipe, backrush place interval has gap, and the tail end edge of cushion rubber propulsion tube turns up, and turns up to locate also that the interval has gap, screws with the tail end edge of main suction pipe to cooperate, and the two forms locking or breaks away from.
The cushion rubber guide cone, it is conical that one end is, the other end is cylindrical, body diameter is less than the conical bottom diameter, and column part can be inserted in the main suction pipe, and tapered segment and column part respectively are divided into pintongs vertically, form the wooden fork shape, conical base and cylinder outer rim are integrated, and the centre is run through, and radially section is empty " ten " word.
Cushion rubber dispensing seat, integral body is three parts, and front end is taper, and section is " ten " font,, the centre is annulus, and the back segment section also is to be " ten " font, and " ten " font that front and back are two sections forms four right angles through groove.
Cushion rubber guide cone and cushion rubber dispensing seat are combined into one to inserting.
The cushion rubber guide cone also can be designed to three lobes, and cushion rubber dispensing seat also will be designed to section and be " Y " shape.
Above-mentioned apparatus is after sterilization, and sealing is preserved.Cushion rubber can reach 6-8 in the natural relaxation lower holding time of state.
During clinical use, the doctor takes with thumb and forefinger and takes the photograph little cushion rubber, the front tip part of cushion rubber dispensing seat " ten " word taper is aimed in the cushion rubber aperture, after inwardly propelling reaches minute place, footpath, most advanced and sophisticated cushion rubber dispensing seat " ten " word that faces toward of cushion rubber guide cone is bored inserting, the column part of cushion rubber guide cone is put in the main suction pipe, the expansion of propelling cushion rubber also is enclosed within on the cushion rubber guide cone, when the annulus of cushion rubber dispensing seat advances cushion rubber to reach cushion rubber guide cone bottom, the cushion rubber expansion that reached capacity, the annulus of cushion rubber dispensing seat continues to advance, and cushion rubber breaks away from cushion rubber guide cone bottom, landing also is enclosed within on the main suction pipe.
Cushion rubber is enclosed within on the main suction pipe, just can let go in fact art operation of doctor, with 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 forward the cushion rubber propulsion tube, just cushion rubber is released 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.
