Abstract

The invention belongs to the field of operative medical equipment, and particularly relates to a laparoscope sample extractor. The laparoscope sample extractor is characterized by comprising an inner spoon head and an outer spoon head, wherein the inner spoon head and the outer spoon head can be buckled and stacked together; the outer spoon head is fixed to the lower end of a tube sleeve, the inner spoon head is fixed to the lower end of an inner rod, the inner rod is arranged in the tube sleeve, and a handle is arranged at the upper end of the inner rod. The laparoscope sample extractor can effectively resist extrusion and deformation, the shape of a sample cannot change due to the fact that the sample is wrapped by the inner spoon head and the outer spoon head, the sample can be taken out through a small incision, and therefore operation wounds are reduced and the sample is protected at the same time, it is avoided that the incision extrudes the sample to affect the pathological mechanism, the sample can be repeatedly used, and good economic benefits and social benefits are achieved.

Description

Laparoscopic specimen extractor

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, develop of science and technology, medical science has obtained progress at full speed, modus operandi by traditional open surgery to unit for endoscope operation future development.Almost 90% operation 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 hands Postoperative Specimen need be opened 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 specimen bag bottom gradually, specimen diameter is constantly expanded, must not no longer open large otch could take out specimen, increased operation wound, extended operating time, and otch is easy to specimen bag to tear in specimen taking-up process, cause specimen extruding to break, pathology is exerted an influence.

Summary of the invention

According to above deficiency of the prior art, the technical problem to be solved in the present invention is: a kind of laparoscopic specimen extractor is provided, in laparoscopic surgery, opens little otch and can take out large specimen, and simple to operate, can Reusability.

Laparoscopic specimen extractor of the present invention, comprises the inside and outside spoon head that can fasten and be stacked, and 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 and specimen rigidity parcel can be taken out, and 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, in position-limitting pin mounting groove, be provided with position-limitting pin, 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 to position-limitting pin just in time snaps in position-limitting pin draw-in groove, 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 locking nut is installed on external screw thread.By bearing, can make the rotation of interior bar more flexible, the setting of locking nut can prevent that 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 plasticity arbitrarily under frozen water soaks, the shared volume-diminished of inside and outside spoon head, can conveniently put into patient body, reduce operation wound and operating time, enter the shape that resiles very soon after human body under body temperature effect; Miscellaneous part is made by rustless steel, and rustless steel is durable in use, and convenient sterilizing is processed.

While needing to take out specimen in operation, 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, specimen is wrapped in behind the space of interior spoon head, the formation of outer spoon head, position-limitting pin is inserted in the position-limitting pin draw-in groove of handle locating part (limited block at position-limitting pin top can prevent that position-limitting pin from coming off from handle), now interior spoon head forms this space of label taking with outer spoon head just, external by pulling pipe box that specimen is taken out.

The beneficial effect that the present invention 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 regard to desirable, go out specimen with less otch; reduced operation wound; protected specimen simultaneously; avoided the impact of otch extruding specimen on pathology, can Reusability, there is good economic benefit and social benefit.

The specific embodiment

Below in conjunction with accompanying drawing, embodiments of the invention are described further:

As shown in Fig. 1～4, laparoscopic specimen extractor, comprises the inside and outside spoon head that can fasten and be stacked, and outer spoon head 7 is fixed on pipe box 4 lower ends, and interior spoon head 8 is fixed on interior bar 5 lower ends, 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 are 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 rings and bearing mounting groove interference fit, interior bar 5 is middle thick, the thin multidiameter in two ends, the inner ring interference fit of the thin axle of interior bar 5 and bearing 2, bearing 2 inner ring end faces lean against on the shaft shoulder of interior bar 5 multidiameters, and there is external screw thread the lower end of interior bar 5, and locking nut 6 is installed on external screw thread; Inside and outside spoon head in this laparoscopic specimen extractor preferably adopts memorial alloy material, and miscellaneous part adopts stainless steel.
