Description

Urethrocystoscope sheath cover

Technical field:

This utility model relates to a kind of urethrocystoscope sheath cover, and it is the important component part in clinical examination and operation technique, belongs to technical field of medical instruments.

Background technology:

The illness of human body urethra and bladder is more, uses urethrocystoscope to do inspections, operation, and is directly perceived, correct because of it, and can forever stay multiple advantages such as dynamically recording, by the extensively employing of clinical treatment institute.Urethrocystoscope generally is made up of endoscope, operating forceps, operator, Jing Qiao, sheath cover and obturator, and the sheath cover is the important composition parts of urethrocystoscope in clinical examination and operation technique.Present widely used sheath cover is made of copper more, adopts soldering technology, and electroplating processes is done on the surface, be connected with adopting latch hook shape draw-in groove between other ingredients of urethrocystoscope, there is following defective in it: 1, latch hook shape draw-in groove complex structure, and the location is inaccurate during dismounting, operates more loaded down with trivial details; 2, sheath main body and sheath pipe are welded between the part, all be connected by soldering between sheath main body and the left and right outlet valve, and casting in bronze soldering technology is relatively poor for the resistance of high temperature and corrosive atmosphere, and electroplating surface are handled harmful; 3, the be welded head of part of sheath pipe is made through after the metal stretching processing, and is thin sharper keen, easily scratch human body urethral tissue.

Summary of the invention:

The purpose of this utility model provides a kind of urethrocystoscope that can overcome above-mentioned defective of the prior art sheath cover, this urethrocystoscope is elegant in appearance with the sheath cover, and corrosion-and high-temp-resistant is rational in infrastructure, simple to operate, convenient, safe, effective in clinical examination and operation use.

This utility model solves the problems of the technologies described above the technical scheme that is adopted: this urethrocystoscope comprises the sheath main body with the sheath cover, the sheath pipe part that is welded, left side water valve and right water valve, collar and back-up ring before described sheath main body is provided with, the sheath cover is whole to be made by stainless steel material, the sheath pipe is welded between part and the sheath main body by laser weld, connects by hickey between sheath main body and the left and right water valve and uses the epoxide-resin glue sealing and fixing.

Collar is positioned at the afterbody of sheath main body before of the present utility model, comprises button, eccentric hoop and positioning convex, and red circle is wherein arranged on the button.

Back-up ring of the present utility model is positioned at the be welded joint portion of part and sheath main body of sheath pipe.

The be welded inwall place in part header operations hole of sheath pipe of the present utility model is welded with one deck stainless steel metal sheet.

This utility model compared with prior art, have the following advantages and effect: the sheath cover is whole to be made by stainless steel material, elegant in appearance, the sheath pipe is welded and passes through laser weld between part and the sheath main body, connect by hickey between sheath main body and the left and right water valve and use the epoxide-resin glue sealing and fixing, corrosion-and high-temp-resistant, harmless.The sheath cover is connected by the coupling of 7 font draw-in grooves on other parts of preceding collar and urethrocystoscope, and preceding collar is positioned at the afterbody of sheath main body.The above and below of pro-collar and sheath main body connecting portion be provided with in guide pin and outer guide pin, in conjunction with the positioning convex on the preceding collar, accurate positioning when having guaranteed dismounting, easy and simple to handle.A back-up ring has been installed in the be welded joint portion of part and sheath main body of sheath pipe, has increased waterproof effect.The be welded inwall place of part head of sheath pipe is welded with one deck stainless steel metal sheet, has also played the effect of passivation when gaining in strength, and can effectively prevent scratch human body urethral tissue.

Description of drawings:

Fig. 1 is the structural representation front view (part is analysed and observe) of this utility model embodiment.

Fig. 2 is the structural representation vertical view (part is analysed and observe) of this utility model embodiment.

The specific embodiment:

Referring to Fig. 1, Fig. 2, component relationship of the present utility model is: be provided with the sheath pipe part 1 that is welded, back-up ring 2, sheath main body 3, right water valve 4, left water valve 5, interior guide pin 6, preceding collar 7, collar spring 8, outer guide pin 9, button 7-1, eccentric hoop 7-2, positioning convex 7-3.

Embodiment of the present utility model is: be welded part 1 and sheath main body 3 of sheath pipe is connected by laser weld, and back-up ring 2 is enclosed within sheath main body 3 and sheath pipe and is welded on the position that part 1 is connected; Right water valve 4 and left water valve 5 are connected the left and right sides of sheath main body 3 and use the epoxide-resin glue sealing and fixing by hickey; Sheath main body 3 is fixing with preceding collar 7 by the outer guide pin 9 that is positioned at the guide pin 6 directly over its afterbody and be positioned under its afterbody; Before collar 7 integral body comprise button 7-1, eccentric hoop 7-2 and two positioning convex 7-3, button 7-1 is positioned at the top of eccentric hoop 7-2, the right and left that two positioning convex 7-3 are positioned at eccentric hoop 7-2 inboard is used for two grooves couplings with sheath main body 3 afterbodys; Button 7-1 before collar spring 8 is positioned on the collar 7, and be enclosed within on the interior guide pin 6 that passes eccentric hoop.

Use of the present utility model is: urethrocystoscope by being connected with parts such as the operator of the preceding collar 7 of 7 font draw-in grooves couplings and urethrocystoscope, obturator, sight glass bridges, is operated very easy with the sheath cover.During actual the use, the red circle of button 7-1 on the preceding collar 7 of the red point on the 7 font draw-in groove positions of parts such as the operator of urethrocystoscope, obturator, Jing Qiao and sheath cover is alignd, in the eccentric hoop 7-2 of collar 7, two positioning convex 7-3 of eccentric hoop inboard will be stuck in the 7 font draw-in grooves and with both and fix on the preceding collar 7 before direction was inserted according to this then.When changing the parts in the sheath cover, the button 7-1 before only need pressing on the collar 7, it is downward to drive eccentric hoop 7-2, and then two of the eccentric hoop inboard positioning convex 7-3 will break away from 7 font draw-in grooves, and it is very convenient to take out parts.When the sheath cover is carried out cleaning and sterilizing, only need open left water valve 5, injecting cleanout fluid, to clean the sheath cover inner, closes left water valve 5 then, opens right water valve 4 and discharge cleanout fluid and get final product.
