Description
Technical field：
The invention belongs to technical field of medical instruments, more particularly to a kind of Flexible ureteroscope biopsy forceps.
Background technology：
Flexible ureteroscope more can easily enter epimere ureter and renal plevis that ureterscopy is difficult to reach, realize to this
Detecting for position, completes the diagnosis and treatment of the disease such as calculus and tumour.Rock breaking tool mainly has electrohydraulic lithotrite under soft lens
（EHL）, pulsed dye laser and Bladder stone, lithotrity effect is fine.But for suspected tumor, soft lens, which can only be observed by the naked eye, to be reached
To empirical diagnosis, but it is difficult to cut preferable biopsy specimen, completes pathological diagnosis, " hard mirror can't reach, and soft lens takes not for formation
To " difficult situation.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
When the prior art for being considered as recognizing or implying the information structure in any form well known to persons skilled in the art.
The content of the invention：
It is capable of the Flexible ureteroscope biopsy forceps of cutting tissue sample it is an object of the invention to provide a kind of, so as to overcome above-mentioned existing
There is the defect in technology.
To achieve the above object, the invention provides a kind of Flexible ureteroscope biopsy forceps, including：Expansion link and axial kink
Handle outside it, the axial length of the expansion link is more than the axial length of handle；
One end of handle is provided with handle, and the telescopic rod end of side is provided with draw ring corresponding thereto, is equipped between handle and draw ring
Both are made to tend to the elastomeric element of compact state；
Be equipped between the other end of handle and the expansion link of corresponding side one by metal wire knitted into metal net bag, in drawing
Stretch under state, the greatest axial length of metal net bag and expansion link free end stretch out handle length it is basically identical.
Using the design concept of this middle string bag, applicant is to make the bone of " lantern " from once viewing craftsman
The inspiration being subject to after frame, its advantage is：In use, being driven by out-draw contracting bar, wire in the stress that expansion link bounces back
Gap between lower natural torsion, adjacent two one metal wire is inevitably enlarged, so as to directly form the window that can conveniently sample（And
And the size of window can be adjusted according to stretching distance）；When not in use, wire is under the overhanging stretching action of expansion link
Naturally it is exceptionally straight, be also achieved that the state bounced back to handle side, can so ensure that the external diameter of at this time metal net bag will not be big
In handle, such design may insure that doctor need not expand wound and just easily stretch into biopsy forceps from wound portion.
The technical scheme that further limits of the present invention as：
Preferably, in above-mentioned technical proposal, biopsy forceps has：Expansion link by the force-extension opposite with elastomeric element elastic force,
The sampling state that handle is moved axially along expansion link inner chamber to elastomeric element side, metal net bag bending is extended out；
And expansion link is not bounced back to original state, handle along expansion link inner chamber to metal net bag side axle by external force, elastomeric element
Stretched to movement, the metal net bag and press close to the original state of handle side wall.
When preferably, in sampling state, metal net bag curved expansion portion at least local external diameter is more than the outer of handle
Footpath, it is so convenient to obtain tissue sample；During in original state, metal net bag gabarit diameter a little be respectively less than the outer of handle
Footpath, so facilitates biopsy forceps to stretch out wound after stretching into wound and biopsy forceps sampling.
Preferably, in above-mentioned technical proposal, metal net bag is mainly by some metals being circumferentially distributed on the outside of expansion link
Silk is surrounded；The main body of single metal wire is fixed on one end of handle along length of telescopic bar directional spreding, its two ends and its is corresponding
The flexible bar side wall of side.
Preferably, in above-mentioned technical proposal, in addition to high frequency electric electric supply installation, high frequency electric electric supply installation passes through wire
Be electrically connected metal net bag.
Preferably, in above-mentioned technical proposal, the spacing between at least two adjacent wires is more than other adjacent wires
Between spacing, this be setting one sample tap, be cased with addition to the larger wire of adjacent spacing, on other wires absolutely
Edge material, this two one metal wire conduction is conveniently cut and obtains sample.
Preferably, elastomeric element is extension spring.
Compared with prior art, the present invention has the advantages that：
The collection of vivo sample is completed by the bending and contraction of metal net bag, further, can be matched somebody with somebody by high-frequency electrical
Metal net bag is closed to extract and collect in-vivo tissue sample.
Brief description of the drawings：
Fig. 1 is original state structural representation of the invention；
Fig. 2 is sampling status architecture schematic diagram of the invention；
Fig. 3 is the top view of metal net bag；
In figure：Handle 1, expansion link 2, spring 3, handle tail end fingerstall 4, expansion link tail end fingerstall 5, metal net bag 6, insulate warp

Embodiment：
Below to the present invention embodiment be described in detail, it is to be understood that protection scope of the present invention not by
The limitation of embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other
Element or other parts.
Embodiment 1：
A kind of Flexible ureteroscope biopsy forceps, as shown in figure 1, including：The handle 1 of expansion link 2 and axial kink outside it, stretches
The axial length of contracting bar 2 is more than the axial length of handle 1；
One end of handle 1 is provided with handle tail end fingerstall 4, and the telescopic rod end of side is provided with expansion link tail end fingerstall 5 corresponding thereto,
The spring 3 for making both tend to compact state is equipped between handle tail end fingerstall 4 and expansion link tail end fingerstall 5；
Be equipped between the other end of handle 1 and the expansion link of corresponding side 2 one by metal wire knitted into metal net bag 6, gold
Belong to the string bag 6 as shown in figure 3, the main groups of metal filaments interweaved by some longitudes and latitudes is into being circumferentially distributed in the outside of expansion link 2；Wherein
The tinsel of warp-wise distribution（For example insulate warp 7, conductive warp 8）Main body along length of telescopic bar directional spreding, its two ends
It is fixed on one end of handle and the flexible bar side wall of its corresponding side, the tinsel of Zonal propagations（For example insulate parallel 9）Bag
It is wound on the tinsel periphery of warp-wise distribution.
