Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical solution of the utility model is described in further detail, but does not form any restriction of the present utility model.
Embodiment 1
As shown in Figures 1 to 6, a kind of attraction sheath, comprise joint, described joint comprises supervisor 1 and arm 2, what arm 2 tilted is arranged on supervisor 1, a wide-angle bending can be formed at the transition position of arm and supervisor, the original vertical attraction of ratio, make calculus more easily level and smooth by arm sucking-off, be provided with syndeton in one end of supervisor 1, be connected with sheath pipe 3 by syndeton, in sheath pipe 3, be provided with convergent divergent channel 6, be provided with closing structure 7 at the other end of supervisor 1, described closing structure 7 offer endoscope pipe accommodation hole 8.Arm 2 tilts with supervisor 1, can form a wide-angle bending at arm 2 and the transition position of being responsible for 1, than original vertical attraction, make calculus more easily level and smooth by arm 2 sucking-off.In use, first sheath pipe 3 and convergent divergent channel 6 are fitted through in human body natural's pipeline or the hole that cut and insert operative site, reach in the organ of calculus, then convergent divergent channel is extracted, form passage in sheath pipe indwelling body, penetrated by the mirror Guan Youjing pipe accommodation hole 8 of endoscope, in the instrument channel of endoscope, insertion instrument carries out rubble, then the external suction pump of arm 2 is utilized, by calculus by arm 2 sucking-off.Arm 2 offers and attracts to control mouth 4, it is strip finedraw that described attraction controls mouth 4, and the length of finedraw is 3 ~ 10mm, and wide is 2 ~ 8mm, and attracting to control mouth 4 is the finedraw that can control aperture, and the minimum aperture of finedraw is completely closed.Closing structure 7 is offered mirror pipe accommodation hole 8, facilitate endoscope with attract sheath with the use of, improve the operability of product.Meanwhile, closing structure 7 can stop flushing current to flow out.As shown in the partial sectional view A of Fig. 6, described sheath pipe 3 is provided with spring and reinforces interlayer 31, it has resistance to compression, has certain elastic bending restoring force, and the inner side that interlayer 31 is arranged on sheath pipe 3 reinforced by this spring, is closely connected with sheath pipe 3, connected mode can be connected by adhesive or other mode connects, in this case, effectively can avoid the distortion of sheath pipe 3, even if because when negative pressure is delivered to sheath pipe 3, due to the existence of inner support power, still can keep close to 0 deformation.
As preferably, described syndeton is be opened in the ladder axial plane 5 on the inwall of supervisor 1 one end, and the diameter of ladder axial plane 5 is successively decreased to closing structure 7 one end by syndeton one end, the outside wall surface interference fits of the internal face that syndeton diameter is larger and sheath pipe 3.Syndeton on supervisor 1 is exactly to supervisor 1 be connected with sheath pipe 3, utilizes the interference fits structure of axis hole, handled easily and processing, also facilitates the sterilization of each parts and safeguard to change.
As preferably, described closing structure 7 comprises the sealed gum cap removably connected with supervisor 1 end, and the centrage of described endoscope pipe accommodation hole 8 overlaps with supervisor's 1 centrage.Facilitate the insertion of endoscope, make the operation of endoscope more convenient, and conveniently allow rubble by being responsible for the linkage section of 1 to arm 2, then discharge.
As preferably, described arm 2 is one-body molded with supervisor 1, and arm 2 forms " Y " font with supervisor 1, and arm 2 is acute angle with the angle of closing structure 7 one end being responsible for 1.Arm 2 tilts to close mechanism one end, makes arm 2 be acute angle with the angle of closing structure 7 one end.Rubble enters supervisor 1 then by arm 2 sucking-off by syndeton one end, and therefore arm 2 is obtuse angle with the angle of the supervisor 1 being provided with sheath pipe 3 one end, rubble can be allowed to pass through more smoothly, raise the efficiency.
As preferably, the length of convergent divergent channel 6 described is as shown in Figure 3 greater than the length of sheath pipe 3, or the length of convergent divergent channel 6 is as shown in Figure 5 greater than supervisor 1 length after being provided with sheath pipe 3.The length of convergent divergent channel 6, slightly larger than sheath pipe 3 length, allows the end of convergent divergent channel 6 expose sheath pipe 3, during use, first convergent divergent channel 6 and sheath pipe 3 is inserted operative site, then extracts convergent divergent channel 6, be connected by sheath pipe 3, then insert endoscope with joint.And when the length of convergent divergent channel 6 is greater than sheath pipe 3, when being greater than the length sum of sheath pipe 3 and supervisor 1 in other words, sheath pipe 3 can be made of one with joint, then take off the sealed gum cap of joint-closure mechanism one end, convergent divergent channel 6 is penetrated in sheath pipe 3 by supervisor 1, then passes to operative site, after reaching the organ of calculus, extract convergent divergent channel 6, cover sealed gum cap, then penetrate endoscope and perform the operation.Two kinds of different structures meet different user demands.
As preferably, the external diameter of endoscope pipe is less than the diameter of supervisor 1, the external diameter of endoscope pipe and the equal diameters of accommodation hole 8 or the diameter slightly larger than accommodation hole 8, as the 1.1-1.2 for accommodation hole 8 diameter doubly.The diameter of endoscope pipe is much smaller than the internal diameter of supervisor 1, therefore when inhaling little calculus, calculus can by supervisor 1 to arm 2 directly sucking-off, when running into larger-diameter calculus, endoscope can be withdrawn into the rear side of supervisor 1 and arm 2 intersection, allow bulk calculus enter arm 2 by being responsible for 1, and then sucking-off is external.The external diameter of endoscope, slightly larger than the diameter of accommodation hole 8, can utilize the elasticity of sealed gum cap to be sealed with the sealed gum cap place of combining by the mirror pipe of endoscope, improves the safety and stability that operating theater instruments uses.
First convergent divergent channel 6 and sheath pipe 3 are inserted in actual applications operative site as, the human body natural such as urethra, ureter pipeline, then extracts convergent divergent channel 6, is connected by sheath pipe 3, then inserts endoscope with joint.And when the length of convergent divergent channel 6 is greater than sheath pipe 3, when being greater than the length sum of sheath pipe 3 and supervisor 1 in other words, sheath pipe 3 can be made of one with joint, then take off the sealed gum cap of joint-closure mechanism one end, convergent divergent channel 6 is penetrated in sheath pipe 3 by supervisor 1, then passes to operative site, after reaching the organ of calculus, extract convergent divergent channel 6, cover sealed gum cap, then penetrate endoscope and perform the operation.
Embodiment 2
Substantially identical with embodiment 1, different places exists, and as shown in the partial sectional view A of Fig. 7, the outside that interlayer 31 is arranged on sheath pipe 3 reinforced by spring, is closely connected, as made it to be closely connected by binding agent or other connected mode with sheath pipe 3.
The outside that interlayer 31 is arranged on sheath pipe 3 reinforced by spring, maintains sheath pipe 3 inner wall smooth on the one hand, on the other hand, effectively reduces the internal distortions of sheath pipe 3.
Embodiment 3
Substantially identical with embodiment 1, different places exists, and as shown in the partial sectional view A of Fig. 8, the inside that interlayer 31 is arranged on the sheath wall of sheath pipe 3 reinforced by spring.
In this case, take into account the advantage of 0 deformation of sheath pipe 3 inner wall smooth and sheath pipe 3 inner wall smooth, and sheath pipe 3 and spring can be reduced reinforced the risk that interlayer 31 is separated.
Above-describedly be only preferred embodiment of the present utility model, all do in spirit of the present utility model and spirit any amendment, equivalently to replace and improvement etc., all should be included within protection domain of the present utility model.
