Abstract
The utility model discloses a kind of disposable extraction bags, including loop bar, wherein: described loop bar one end is equipped with handle, expansion screw is equipped in loop bar, expansion screw one end is fixedly connected after passing through handle and pushing block with locating piece, and the other end is fixedly connected with expanding ring, and expanding ring is equipped with extraction bag, internal screw thread is equipped in pushing block, pushing block is connected through a screw thread with expansion screw.The utility model realizes that extraction bag is steadily quickly opened and shunk by the cooperation of pushing block and expansion screw, to avoid injury of the loop bar to tissue；By the way that expansion screw is arranged in loop bar, effectively reduction memory alloy material used in expanding ring can be prepared, to reduce enterprise's production cost.
Description
Technical field
The utility model relates to the field of medical instrument technology more particularly to a kind of disposable extraction bags.
Background technique
In micro-wound surgical operation, after the pathological tissues of excision are removed by instrument, put into disposable extraction bag and draw
It is external out.Existing extraction bag typically realizes the opening and contraction of extraction bag by directly push-and-pull, although structure is simple,
But directly push-and-pull be easy to cause rushing for loop bar front end in the course of surgery, to damage to tissue, increases
The risk of operation, while increasing the pain of patient.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide one kind and are easy to implement extraction bag opening and shrink
Disposable extraction bag.
The technical solution of the utility model is as follows: a kind of disposable extraction bag, including loop bar, in which: the loop bar
One end is equipped with handle, and expansion screw is equipped in loop bar, and expansion screw one end, which is fixed after handle and pushing block with locating piece, to be connected
It connects, the other end is fixedly connected with expanding ring, and expanding ring is equipped with extraction bag, is equipped with internal screw thread in pushing block, pushing block and flexible
Screw rod is connected through a screw thread.
Preferably, the expanding ring is made of memory alloy material.
Preferably, the extraction bag is made of TPU material.
Preferably, the pushing block side is equipped with through-hole.
The technical effect and advantage of the utility model:
1, realize that extraction bag is steadily quickly opened and shunk by the cooperation of pushing block and expansion screw, to avoid covering
Injury of the bar to tissue；
2, by the way that expansion screw is arranged in loop bar, effectively reduction memorial alloy material used in expanding ring can be prepared
Material, to reduce enterprise's production cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1- loop bar, 2- handle, 3- pushing block, 4- expanding ring, 5- extraction bag, 6- expansion screw, 7- internal screw thread, 8-
Through-hole.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, a kind of disposable extraction bag, including loop bar 1, in which: described 1 one end of loop bar is equipped with handle 2,
Expansion screw 6 is equipped in loop bar 1,6 one end of expansion screw is fixedly connected after passing through handle 2 and pushing block 3 with locating piece 9, another
End is fixedly connected with expanding ring 4, and expanding ring 4 is equipped with extraction bag 5, is equipped with internal screw thread 7, pushing block 3 and flexible spiral shell in pushing block 3
Bar 6 is connected through a screw thread, convenient for driving expansion screw 6 mobile.
As the preferred embodiment of the utility model, expanding ring 4 is made of memory alloy material, is conducive to sack and sufficiently opens
It opens, it is indeformable, so that convenience sample is put into.
As the preferred embodiment of the utility model, extraction bag 5 is made of TPU material, convenient for observation confirmatory sample
It is put into extraction bag 5, while avoiding breakage that tissue fluid leakage is caused to pollute.
As the preferred embodiment of the utility model, 3 side of pushing block is equipped with through-hole 8, convenient for driving pushing block 3 to rotate forward and
Reversion.
In use, 1 front end of loop bar is placed in appropriate location, pushing block 3 is rotated backward by through-hole 8, by pushing block 3
Internal screw thread 7 be moved along expansion screw 6, expansion screw 6 pushes expanding ring 4 and extraction bag 5 to move outward, until expanding ring
4 drive extraction bag 5 to open, and the sample of well cutting is put into extraction bag 5, pushing block 3 is rotated forward by through-hole 8, passes through promotion
Internal screw thread 7 on block 3 drives expansion screw 6 to move backward, and expansion screw 6 pushes expanding ring 4 and extraction bag 5 to move in loop bar 1
It is dynamic, to realize the sealing of 5 openning of extraction bag, slowly takes out loop bar 1 and complete operation.
The above is only the preferred embodiment of the utility model, not imposes any restrictions to the utility model, all
According to any simple modification to the above embodiments of the utility model technical spirit, change and equivalent structural changes, still
Belong in the protection scope of technical solutions of the utility model.
