Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of natural tract material extractor for endoscopic surgeries, is applicable to the operation of nature tract.
Background technology
On existing market, supply is the endoscopic surgery load-engaging device of the Trocar apparatus of 10mm, 5mm, with have the Minimally Invasive Surgery of otch with the use of.Along with the development of Wicresoft's endoscopic technic, the requirement of people to Minimally Invasive Surgery is more and more higher, and natural tract operation, due to non-incision, is subject to clinical welcome.The sleeve outer of common endoscopic surgery load-engaging device is about 8mm, curtailment 1m, and sleeve pipe use material be plastic conduit, mostly cannot perform the operation with natural tract (such as intestinal mirror, gastroscope, bronchoscope) with the use of.For intestinal mirror, its external diameter, less than 3mm, in narrow space like this, makes and has like configurations, and casing length longer to get sundries difficulty larger.Therefore to perform the operation the material extractor for endoscopic surgeries pressing needs used through natural tract with intestinal mirror, gastroscope, bronchoscope etc. clinically.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of natural tract material extractor for endoscopic surgeries.
The purpose of this utility model is realized by following scheme:
A kind of natural tract material extractor for endoscopic surgeries, comprise monaural handle, described monaural handle comprises hollow tubular portion and is arranged on the ear of annular of hollow tubular portion one end, the hollow tubular portion other end is connected with hollow trocar sheath one end, traction steel wire is provided with in hollow tubular portion, hollow tubular portion external activity is arranged with ears handle, the sidepiece of hollow tubular portion offers sliding tray, bolt is provided with in sliding tray, bolt is connected with ears handle and traction steel wire respectively, and traction steel wire one end passes trocar sheath and is connected with collecting bag unit.
Collecting bag unit as above comprises elastic opening silk ring and collecting bag, and the bag mouth of collecting bag is bonded on elastic opening silk ring.
Ears handle as above comprises the ear of the cannula portion be set on monaural handle and the annular arranging cannula portion both sides.
The external diameter of trocar sheath as above is 1mm-4mm, and the length of trocar sheath is 1.5m-3m.
Bolt as above embeds and is arranged in ears handle.
This utility model has the following advantages:
1, structure is simple, easy to use, fills up the blank of this technology domestic.
2, sleeve outer is little, with natural tract mirror with the use of, facilitate the taking-up of foreign body in nature tract videoendoscopic surgery and excision thing.

Detailed description of the invention
Below in conjunction with diagram, concrete structure of the present utility model is described in further detail.
Embodiment 1:
A kind of natural tract material extractor for endoscopic surgeries, comprise monaural handle 1, described monaural handle 1 comprises hollow tubular portion 8 and is arranged on the ear 9 of annular of hollow tubular portion 8 one end, hollow tubular portion 8 other end is connected with hollow trocar sheath 5 one end, traction steel wire 4 is provided with in hollow tubular portion 8, hollow tubular portion 8 external activity is arranged with ears handle 2, the sidepiece of monaural handle 1 offers sliding tray, bolt 3 is provided with in sliding tray, bolt 3 is connected with ears handle 2 and traction steel wire 4 respectively, and traction steel wire 4 one end passes trocar sheath 5 and is connected with collecting bag unit.Collecting bag unit comprises elastic opening silk ring 6 and collecting bag 7, and the bag mouth of collecting bag 7 is bonded on elastic opening silk ring 6.Ears handle 2 comprises the ear 9 of the cannula portion 10 be set on monaural handle 1 and the annular arranging cannula portion 10 both sides.The external diameter of trocar sheath 5 is 1mm-4mm, and the length of trocar sheath 5 is 1.5m-3m.Bolt 3 embeds and is arranged in ears handle (2).
In use, can the annular ear of monaural handle 2 be enclosed within thumb, two of ears handle 2 annular ears are enclosed within forefinger and middle finger respectively, because bolt 3 can move back and forth along the sliding tray being opened in hollow tubular portion 8, and bolt 3 is fixedly connected with traction steel wire 4 with ears handle 2 respectively, and ears handle 2 is movably set on hollow tubular portion 8, therefore, can be moved back and forth on hollow tubular portion 8 by the distance controlling ears handle 2 of finger, drive bolt 3 to move back and forth in sliding tray simultaneously, and then drive traction steel wire 4 to move back and forth in hollow tubular portion 8.When traction steel wire 4 inside contracts toward trocar sheath 5, due to elastic opening silk ring 6 elastically deformable, drive elastic opening silk ring 6 also in retraction trocar sheath 5, the collecting bag 7 be fixed on elastic opening silk ring 6 is also recovered in trocar sheath 5 simultaneously.When traction steel wire 4 stretch out trocar sheath 5 outer time, due to elastic opening silk ring 6 elastically deformable, drive elastic opening silk ring 6 also to stretch out outside trocar sheath 5, the collecting bag 7 be fixed on elastic opening silk ring 6 also reached outside trocar sheath 5 simultaneously.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
