Description
Technical field
This utility model relates to a kind of assembly, and particularly a kind of operation is with unpluging device assembly, and it belongs to medical apparatus and instruments, is mainly applicable in the cervical operation of human body.
Background technology
In prior art, cervical operation is substantially all conventional artificial operation; But at other as in gastrointestinal surgery, can the surgical assembly such as obturator, epitheca be used, wherein: obturator is primarily of plug, connecting rod and plug handle composition, and they are integrally welded; Epitheca is primarily of epitheca main body, fixed mount and outer tube composition, and they are also integrally welded; During operation, obturator is first inserted in epitheca, then make them enter human body together, after putting in place, transfer to obturator, then the operational tool putting into other needs in epitheca can carry out hands art; But owing to not having setting to unplug device, existing operation method and apparatus are very easy to damage tissue, bring unnecessary misery to patient.
Chinese invention patent application 201210618974X discloses one " endoscope's soft tissue unplugs device ", although it is provided with unplug device, but still there is following shortcoming in actual use: unplug the movable by threaded adjusting of paddle on device, its governing speed is slow, the carrying out of impact operation.
Utility model content
Technical problem to be solved in the utility model to overcome in prior art existing above-mentioned deficiency, and a kind of reasonable in design is provided, when using the little and operation that operative speed is fast of human tissue injury with unpluging device assembly.
The technical scheme in the invention for solving the above technical problem is: this operation comprises the obturator of coupling mutually, interior sheath and epitheca with unpluging device assembly, the external diameter of obturator middle front part is less than the internal diameter of epitheca outer tube, epitheca is a hollow structure, it is characterized in that: described interior sheath comprises pipe and interior sheath main body in paddle, interior sheath outer tube, interior sheath, in described interior sheath, pipe and interior sheath main body are hollow structure, paddle is welded in interior sheath on pipe, and in interior sheath, pipe and interior sheath outer tube are all welded in interior sheath main body; The hollow structure of described epitheca main body is provided with slope.Make this utility model tissue can be unpluged when performing the operation thus, convenient operation, not easy damaged tissue, and operative speed is fast.
Its one end, slope in epitheca main body described in the utility model and the internal diameter of epitheca match, and the other end is provided with 0 RunddichtringO.So that penetrating fast of interior sheath, thus the carrying out of convenient operation.
Interior sheath main body described in the utility model is provided with groove, to coordinate with 0 RunddichtringO.
Paddle described in the utility model has five, and they, by 200 ° of distributions, to unplug tissue, make surgical field of view more open expansion.
This utility model compared with prior art, has the following advantages and effect: reasonable in design, unplugs device owing to being provided with, and can unplug tissue during use, damages little; The movable of paddle is realized by sheath in direct push-and-pull, and the technical operation time is short, and operative speed is fast, and in cervical operation, easy to use, reliable and safety, the resultant effect of operation is better.

Detailed description of the invention
See Fig. 1-Fig. 5, this utility model forms primarily of obturator 1, epitheca 2 and interior sheath 3; Obturator 1 comprises plug 11, connecting rod 12 and plug handle 13, and they are integrally welded; Epitheca 2 comprises epitheca main body 21, fixed mount 22 and outer tube 23, and they are also integrally welded; Epitheca main body 21 is also provided with 0 type circle 24; The external diameter of obturator 1 middle front part is less than the internal diameter of the outer tube 23 of epitheca 2, and epitheca 2 is a hollow structure, to penetrate other operational tool needed; The hollow structure of epitheca main body 21 is provided with slope 211, the internal diameter of this its one end, slope 211 and epitheca 3 matches, and the other end is provided with 0 RunddichtringO 24.
Interior sheath 3 of the present utility model comprises pipe 32 and interior sheath main body 33 in paddle 31, interior sheath outer tube 34, interior sheath, the external diameter of interior sheath outer tube 34 is less than the internal diameter of the outer tube 23 of epitheca 2, in interior sheath, pipe 32 and interior sheath main body 33 are hollow structure, paddle 31 is welded in interior sheath on pipe 32, and in interior sheath, pipe 32 and interior sheath outer tube 34 are all welded in interior sheath main body 33.
In the present embodiment, paddle 31 is made with corrosion resistant plate, and they are positioned at the front end of sheath pipe 32 and are scattered in umbrella shape shape; Interior sheath main body 33 is provided with groove 331, and it mates with epitheca main body 21 and 0 RunddichtringO 24; Paddle 31 has five, and they are by 200 ° of distributions.
During operation, obturator 1 is first inserted in epitheca 2, then makes them enter human body together, after putting in place, transfer to obturator 1, then penetrate interior sheath 3 by the slope 211 on epitheca 2; Because the paddle 31 on interior sheath 3 has certain elasticity, when pushing and pull out epitheca 2, operation is all very convenient; When pushing epitheca 2 and after entering human body, they can strut automatically, be separated and unplug the soft tissue of human body, the operational tool facilitating other to need penetrates in interior sheath and performs the operation in pipe 32, makes surgical field of view more open expansion; After operation terminates, as long as sheath 3 in pull-out, paddle 31 can bounce back and be drawn out epitheca 2 together with interior sheath 3.
This utility model can be made with rustless steel.
All equivalences of doing according to structure, feature and the principle described in this utility model inventional idea or simple change, be included in the protection domain of this utility model patent.
