Description
Technical field
The present invention relates to a kind of puncture outfit with fixed structure.
Background technology
At present, disposable celiac mirror puncture outfit, generally increased using screw thread that big epitheca wall carries in itself is punctured and
Skin friction power is to fix puncture outfit.Existing helicitic texture puncture outfit, although simple structure, but operation wound is relatively
Greatly, and doctor puncture when need rotation to penetrate abdominal cavity, extracted in the same way again after the completion of operation, cause to operate pole
Big inconvenience.
The content of the invention
It is an object of the invention to provide a kind of puncture outfit with fixed structure, it can reduce operation wound, and more
Plus facilitate doctor puncture outfit to be penetrated and extracted the operation in abdominal cavity.
The purpose of the present invention is achieved through the following technical solutions：A kind of puncture outfit with fixed structure, it includes epitheca
Head end, be nested in epitheca head end and can relative epitheca head end move up and down movable epitheca, outside epitheca head end and activity
The relative elastic component moved down of holding activity epitheca between sheath, the inner tube being fixedly connected through movable epitheca and with epitheca head end and
It is sheathed on the inner tube that inner tube is outer and is fixedly connected with movable epitheca；Said inner tube lower end is fixed with outer tube lower end；The outer tube is set
There is the fixed part for moving down and strutting with movable epitheca.
For prior art, the advantage of the invention is that：
(1) pushed away under elastic component under effect, movable epitheca is moved down with respect to epitheca termination, drive outer tube to move down, promote solid
Determine portion to strut, to hang on abdominal wall side, reach fixation；When overcoming elastic component lower thrust to pull up movable epitheca, outside
Pipe moves up drive fixed part and shunk, and puncture outfit can be extracted easily, convenient operation technique；
(2) as long as doctor's finger catches on pull handle, movable epitheca is just can move up, operation is all the more facilitated；
(3) cooperation of spacer pin and positioning convex, the volume that effectively control fixed part is strutted, and prevent movable epitheca from deviating from
Epitheca termination；
(4) the V-arrangement piece for tightly being covered but being strutted in can be moved up and down with respect to outer tube this design, with outer tube using retainer ring is coordinated
Use, more preferable fixed effect is obtained when puncture outfit is hung on abdominal wall side.

Embodiment
Present invention is described in detail with reference to Figure of description and embodiment：
As shown in Figures 1 to 5, a kind of puncture outfit with fixed structure, it includes epitheca head end 1, is nested in epitheca head
Hold 1 interior and the energy movable epitheca 2 that epitheca head end 1 is moved up and down relatively, the holding work between epitheca head end 1 and movable epitheca 2
Move the relative elastic component 3 for moving down trend of epitheca 2, the inner tube 4 being fixedly connected through movable epitheca 2 and with epitheca head end 1 and set
Located at the outer tube 5 that inner tube 4 is outer and is fixedly connected with movable epitheca 2；The lower end of said inner tube 4 is fixed with the lower end of outer tube 5；The outer tube
5 provided with the fixed part for moving down and strutting with movable epitheca 2.
The movable epitheca 2 is provided with the pull handle 6 being located at outside epitheca head end 1.
Said inner tube 4, by the interior sheath head end 7 in epitheca head end 1, is fixedly connected with epitheca head end 1.
The described puncture outfit with fixed structure, it is also included located at the sealing between epitheca head end 1 and interior sheath head end 7
Circle 8, so as to ensure the air-tightness between epitheca head end 1 and interior sheath head end 7.
The epitheca head end 1 is equipped with spacer pin 9；The periphery of the movable epitheca 2 is provided with and determining that spacer pin 9 coordinates
Position projection 21.
The fixed part is included along the circumferential multi-disc V-arrangement piece 51 laid of inner tube 4.
In order to allow fixed part when using it is more stable, when the fixed part is strutted, each V-arrangement piece 51 and the outer wall structure of inner tube 4
Into stable triangle.
The outer tube 5 is made up of plastics, memory metal (such as Nitinol) or other elastomeric materials.
The puncture outfit with fixed structure, it also includes being tightly placed in the fixation that outer tube 5 is outer and is located above fixed part
Ring 12.The retainer ring 12 be able to can move up and down in the outer surface of outer tube 5, mainly the V-arrangement piece cooperation with being strutted on outer tube 5
Use, to hang on abdominal wall side, reach fixation
Application method is as follows：When initial, fixed part is in softened state；When beginning to use, finger is caught on movable epitheca 2
Pull handle 6 up pull, make V-arrangement piece 51 on outer tube 2 be in straight condition；Puncture outfit penetrates release pull handle 6, outer tube behind abdominal cavity
V-arrangement piece 51 on 2 automatically restores to initial softened state under the elastic force effect of elastic component 3；Afterwards, according to abdominal cavity wall thickness
The position of retainer ring 13 is adjusted, reaches and fastens simultaneously up and down, be just operated；Equally it is on outer tube 2 after the completion of operation
V-arrangement piece is controlled in straight condition, and now puncture outfit can exit abdominal cavity, completes operation technique.
