Abstract
The invention discloses the rotatable elbow biopsy forceps under a kind of surgery centesis, including biopsy caliper, the biopsy caliper is including the biopsy binding clip for gripping human lesion tissue, the zip being connected with biopsy binding clip and parcel zip and in the outer sheath of hollow structure, the zip is slidably arranged in the hollow part of outer sheath, the outer sheath free end is made up of flexible material, and outer sheath axle center is deviateed and towards lateral bend outside outer sheath axle center in the outer sheath free end.Because outer sheath axle center is deviateed and towards lateral bend outside outer sheath axle center in outer sheath free end in the present invention, the zip being connected with biopsy binding clip slides the hollow part for being arranged in outer sheath, therefore the biopsy binding clip positioned at outer sheath free end is towards lateral bend outside endoscope channel perisporium, it is easy to biopsy binding clip to grip the pathological tissues at the position, operation difficulty is greatly reduced, operating efficiency is improved.
Description
Technical field
The invention belongs to field of medical technology, and in particular to the rotatable elbow biopsy forceps under a kind of surgery centesis.
Background technology
Endoscopy is as a kind of method of auxiliary diagnosis, and what is used in clinical medicine inspection is more and more extensive, living
Inspection pincers are that endoscopy takes the indispensable instrument of Pathologic specimen, and coup injury mucous membrane is to obtain sample.Biopsy forceps can lead to
Cross endoscope channel to extend into patient body, diseased region is checked, grip pathological tissues.At present in clinical practice
In, biopsy forceps is widely applied, and it is that doctor carries out pathological diagnosis to digestive disease.
Fig. 1 is existing the more commonly used biopsy forceps structural representation, as shown in figure 1, biopsy forceps generally includes biopsy caliper
1 ' and operation shank 2 ', biopsy caliper 1 ' include be used for grip human lesion tissue biopsy binding clip 11 ', with biopsy binding clip
11 ' connection zips 12 ' and parcel zip 12 ' and in hollow structure outer sheath 13 ', operate the operable zip of shank 2 '
12 ' slide the hollow part for being arranged in outer sheath 13 ', and zip 12 ' is connected with biopsy binding clip 11 ', can adjusted by zip 12 '
Save biopsy binding clip 11 ' and realize gripping work, therefore zip 12 ' is during slip is arranged in the hollow part of outer sheath 13 ',
Opening or closing for the clamp port of regulation biopsy binding clip 11 ' is realized simultaneously.It is when using above-mentioned biopsy forceps, biopsy caliper 1 ' is logical
Cross endoscope channel to stretch into patient body, pathological tissues are gripped by biopsy binding clip 11 ', because endoscope channel is by biopsy caliper
1 ' is limited in endoscope channel, and biopsy binding clip 11 ' is difficult to be contacted with the pathological tissues on endoscope channel perisporium outside, because
This is not easy to grip the pathological tissues at the position so that operation difficulty increase, reduces operating efficiency.
The content of the invention
In order to solve the above-mentioned technical problem, the invention provides the rotatable elbow biopsy forceps under a kind of surgery centesis,
It is easy to operator to grip human lesion tissue, reduces operation difficulty, improves operating efficiency.
The technical scheme is that：A kind of rotatable elbow biopsy forceps under surgery centesis, including biopsy caliper, institute
Stating biopsy caliper includes being used for the biopsy binding clip for gripping human lesion tissue, the zip and parcel zip that are connected with biopsy binding clip
And in the outer sheath of hollow structure, the zip is slidably arranged in the hollow part of outer sheath, the outer sheath free end
It is made up of flexible material, outer sheath axle center is deviateed and towards lateral bend outside outer sheath axle center in the outer sheath free end.
When the biopsy caliper of the present invention is stretched into body along endoscope channel, due to outer sheath and speculum forceps
Road is coaxial, because outer sheath axle center is deviateed and towards lateral bend outside outer sheath axle center in outer sheath free end in the present invention, with biopsy
The zip of binding clip connection slides the hollow part for being arranged in outer sheath, therefore positioned at the biopsy binding clip direction of outer sheath free end
The outer lateral bend of endoscope channel perisporium, is easy to biopsy binding clip to grip the pathological tissues at the position.
For the ease of regulation zip, preferably, also including being arranged in outer sheath hollow part for manipulating zip slip
Operation shank, the biopsy caliper be fitted to it is described operation shank one end.
Shank is operated there are multiple structural forms in the present invention, using existing biopsy forceps mode of operation, as
It is preferred that, the operation shank include along the axially arranged slide bar of zip and slip cap outside slide bar and with the zip

For the ease of the slip of zip, preferably, guiding slot port is offered on the axial direction of the slide bar, the cunning
Set is provided with the sliding block being slidably matched with guiding slot port, the one end of the zip away from biopsy binding clip with guiding slot port position corresponding position
Outer sheath is leant out, and is fixedly connected with a slide block along axially extending in guiding slot port for slide bar.The sliding block and guide groove of sliding sleeve
The mode that mouth is slidably matched, can cause slip of the sliding sleeve along slide bar more to stablize, and be easy to operator to manipulate the slip of zip
Speed.
Preferably, the operation shank also includes connector, one end fixed cover of the connector is outside outer sheath
Portion, the other end is rotated with the slide bar and is connected.The present invention can cause slide bar to be rotated relative to outer sheath, that is, cause zip outside
The rotation of sheath hollow part, when biopsy binding clip is rotated to pathological tissues position corresponding position, stop the rotation slide bar, only needs weight
The process of multiple above-mentioned manipulation zip, you can gripping pathological tissues.
Preferably, the sliding sleeve is provided with promotes sliding sleeve relative to the first Handheld Division of sliding bar manually for operator.
It is used to rotate relative to connector for operator preferably, the one end of the slide bar away from the connector is provided with
The second Handheld Division that slide bar is rotated.
For the intensity of the junction that strengthens outer sheath and connector, preferably, the outer sheath is close to connector
One end outer cover is provided with rubber protecting jacket.
Preferably, the outer sheath free end is 30~60 ° relative to the deviation angle in the outer sheath axle center.
Preferably, the outer sheath free end is 60 ° relative to the deviation angle in the outer sheath axle center.
Compared with prior art, beneficial effects of the present invention are embodied in：
Because outer sheath axle center is deviateed and towards lateral bend outside outer sheath axle center in outer sheath free end in the present invention, with biopsy
The zip of binding clip connection slides the hollow part for being arranged in outer sheath, therefore positioned at the biopsy binding clip direction of outer sheath free end
The outer lateral bend of endoscope channel perisporium, is easy to biopsy binding clip to grip the pathological tissues at the position, greatly reduces operation difficulty,
Improve operating efficiency.
