Abstract
The invention belongs to surgical medical instrument field, be specifically related to a kind of laparoscopic specimen extractor, it is characterized in that: comprise and can fasten and the inside and outside spoon head be stacked, outer spoon head is fixed on pipe box lower end, interior spoon head is fixed on interior bar lower end, interior bar is placed in pipe box, and the upper end of interior bar is provided with handle.This laparoscopic specimen extractor can effectively anti-extrusion, resistance to deformation; specimen shape under the parcel of inside and outside spoon head can not change; can with less otch just desirable go out specimen; reduce operation wound; protect specimen simultaneously; avoid otch extruding specimen to the impact of pathology, can Reusability, there is good economic benefit and social benefit.
Description
Technical field
The present invention relates to a kind of laparoscopic specimen extractor, belong to surgical medical instrument field.
Background technology
At present along with the making constant progress of science and technology, develop, medical science achieves made rapid progress, modus operandi by traditional open surgery to unit for endoscope operation future development.Almost the operation of 90% all can complete under peritoneoscope, it is little that laparoscopic surgery has wound, perform the operation meticulous, go out insufficiency of blood, recover the feature such as fast, only need the otch of several hours can complete hands art, but the taking-up of Post operation specimen need open corresponding otch according to the size of specimen, although traditional specimen taking-out bag has certain tension force, but intensity is obviously not enough, if otch is too small, when specimen is taken out under the continuous extruding of otch, specimen moves on to bottom specimen bag gradually, specimen diameter is constantly expanded, no longer must not open large otch specimen could be taken out, add operation wound, extend operating time, and otch is easy to specimen bag to tear in specimen taking-up process, cause specimen to extrude to break, pathology is had an impact.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide a kind of laparoscopic specimen extractor, opens minimal incision * and can take out large specimen in laparoscopic surgery, simple to operate, can Reusability.
Laparoscopic specimen extractor of the present invention, comprise and can fasten and the inside and outside spoon head be stacked, outer spoon head is fixed on pipe box lower end, and interior spoon head is fixed on interior bar lower end, and interior bar is placed in pipe box, and the upper end of interior bar is provided with handle.
Inside and outside spoon head fastens can take out specimen rigidity parcel, adapts to the elasticity of abdominal incision, thus otch can be done relatively less, use lever operated, convenient.
Handle is provided with position-limitting pin mounting groove, position-limitting pin is provided with in position-limitting pin mounting groove, pipe box outer upper is provided with handle locating part, handle locating part is provided with the position-limitting pin draw-in groove corresponding with position-limitting pin, when rotary handle just in time snaps in position-limitting pin draw-in groove to position-limitting pin, interior spoon head forms this space of label taking, convenient operation with outer spoon head just.
Pipe box two ends are provided with two bearing mounting grooves, bearing is placed in bearing mounting groove, bearing outer ring and bearing mounting groove interference fit, interior bar is middle thick, the multidiameter that two ends are thin, the inner ring interference fit of the thin axle of interior bar and bearing, bearing inner race end face leans against on the shaft shoulder of interior bar multidiameter, there is external screw thread the lower end of interior bar, and external screw thread installs locking nut.The rotation of interior bar can be made more flexible by bearing, the setting of locking nut can prevent the bearing in interior bar bottom end bearing mounting groove from coming off.
Inside and outside spoon head in this laparoscopic specimen extractor preferably adopts memorial alloy material, memorial alloy can plasticity arbitrarily under frozen water soaks, volume-diminished shared by inside and outside spoon head, conveniently can put into patient body, reduce operation wound and operating time, resile very soon after entering human body shape under body temperature effect; Miscellaneous part is made up of rustless steel, and rustless steel is durable in use, convenient sterilizing process.
When needing in operation to take out specimen, the inside and outside spoon head of laparoscopic specimen extractor is put into human body by operative incision, specimen is put into spoon head, promote position-limitting pin, turning handle, in interior bar drives, spoon head is rotated, behind the space that specimen is wrapped in interior spoon head, outer spoon head is formed, position-limitting pin is inserted into (limited block at position-limitting pin top can prevent position-limitting pin from coming off from handle) in the position-limitting pin draw-in groove of handle locating part, now interior spoon head forms this space of label taking with outer spoon head just, external by pulling pipe box specimen to be taken out.
The beneficial effect that the present invention is compared with prior art had is:
This laparoscopic specimen extractor can effectively anti-extrusion, resistance to deformation; specimen shape under the parcel of inside and outside spoon head can not change; can with less otch just desirable go out specimen; reduce operation wound; protect specimen simultaneously; avoid otch extruding specimen to the impact of pathology, can Reusability, there is good economic benefit and social benefit.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described further:
As shown in figures 1-4, laparoscopic specimen extractor, comprise and can fasten and the inside and outside spoon head be stacked, outer spoon head 7 is fixed on pipe box 4 lower end, and interior spoon head 8 is fixed on interior bar 5 lower end, and interior bar 5 is placed in pipe box 4, and the upper end of interior bar 5 is provided with handle 1.
Wherein: handle 1 is provided with position-limitting pin mounting groove, position-limitting pin mounting groove is built-in with position-limitting pin 9, and pipe box 4 outer upper is provided with handle locating part 3, and handle locating part 3 is provided with the position-limitting pin draw-in groove 10 corresponding with position-limitting pin 9; Pipe box 4 two ends are provided with two bearing mounting grooves, bearing 2 is placed in bearing mounting groove, bearing 2 outer ring and bearing mounting groove interference fit, interior bar 5 is the multidiameter that centre is thick, two ends are thin, the inner ring interference fit of the thin axle of interior bar 5 and bearing 2, bearing 2 inner ring end face leans against on the shaft shoulder of interior bar 5 multidiameter, and there is external screw thread the lower end of interior bar 5, external screw thread is installed locking nut 6; Inside and outside spoon head in this laparoscopic specimen extractor preferably adopts memorial alloy material, and miscellaneous part adopts stainless steel.
When needing in operation to take out specimen, by in laparoscopic specimen extractor, outer spoon head puts into human body by operative incision, after specimen being put into spoon head 8, promote position-limitting pin 9, turning handle 1, interior bar 5 drives interior spoon head 8 to rotate, specimen is wrapped in interior spoon head 8, behind the space that outer spoon head 7 is formed, position-limitting pin 9 is inserted into the position-limitting pin draw-in groove 10 interior (limited block at position-limitting pin 9 top can prevent position-limitting pin 9 from coming off from handle 1) of handle locating part 3, now interior spoon head 8 forms this space of label taking with outer spoon head 7 just, external by pulling pipe box 4 specimen to be taken out.
The present invention can be divided into different models according to the size of inside and outside spoon head, the inside and outside spoon head of respective model may correspond to the specimen of taking out corresponding size, otch as used the inside and outside spoon head of ting model to open 3cm can take out the specimen of 5cm, and the otch using the inside and outside spoon head of middle model to open 5cm can take out the specimen of 10cm.
