Description
Technical field
The utility model belongs to clamping tissue medical instrument when diagnosing the illness, especially a kind of gripping internal body tissues
Biopsy forceps for diagnosing identification, and in particular to be a kind of biopsy forceps of angle adjustable.
Background technology
Inspection pincers are that endoscopy takes the indispensable tool of Pathologic specimen, and coup injury mucous membrane is to obtain sample.Current
Sheath the being integral property sheath of biopsy forceps, angle change with cavity, cannot voluntarily change angle.Biopsy forceps is from lesion group
The operability for knitting the sample that front obtains is strong, and the sample validity of gripping is good, and positive rate is high, it is possible to reduce what disease was failed to pinpoint a disease in diagnosis
Risk.
And during specific clinical manipulation, some pathological tissues be not in into biopsy forceps jaw structure just before
Side results in the degree of difficulty of gripping to increase in this way, and accuracy is inadequate.Therefore need one kind that can adjust biopsy forceps angle,
Make the biopsy forceps of its face pathological tissues gripping sample.
The problem of the utility model is for the bad adjustment of current biopsy forceps angle, devising one kind can solve the above problems
Adjustable angle biopsy forceps.
Utility model content
In order to overcome the problems, such as the bad adjustment of prior art biopsy forceps angle, the utility model provides a kind of angle adjustable
Biopsy forceps.
A kind of biopsy forceps of angle adjustable comprising sleeve, stayed pole, sheath, jaw structure drawing silk, jaw structure,
It is characterized in that, the sleeve connection sheath, the stayed pole connects jaw structure drawing silk, the jaw structure drawing silk other end
Jaw structure is connected, jaw structure part is connect with sheath；In addition one pliable tune is set on rear side of the sheath front end, it is flexible
Section connection sheath front and rear part；Bending section drawing silk is set in sheath, and drawing silk one end is bonded to sheath fore-end and close
Pliable tune, the drawing silk other end are bonded to rotation folding and unfolding and turn round, and rotation folding and unfolding torsion is set to sleeve side walls and both sides all extend
To outside sheath tube wall.The tune of sheath toe angle may be implemented in the setting that pliable tune, bending drawing silk and rear end rotation folding and unfolding are turned round
Section, and then achieve the purpose that adjusting jaw angle, finally make at jaw face sampling tissue, and the structure operation is simply easy.
Further, the pliable tune could be provided as the arbitrary flexible structure of friendship, wherein being preferably arranged to a tool bullet
Property ring.
Further, elastic ring connects front and back two parts of sheath by way of thermoplastic or gluing.
Further, the bending drawing silk is set on the inside of sheath.Being bent setting of the drawing silk on the inside of sheath can save
Save space, and can effectively present drawing silk movement locus, increase the control to being bent drawing silk, prevent to organizing outside sheath
Damage.
Further, bending drawing silk channel is additionally provided on the sheath inside pipe wall.The setting for being bent drawing silk channel can be with
The effectively movement locus of control bending drawing silk, prevents interfering with each other between a plurality of drawing silk.
Further, the stayed pole is set to the top that the rotation folding and unfolding is turned round, and stayed pole does not touch rotation folding and unfolding and turns round.This
Kind setting can ensure that the movement that stayed pole and rotation folding and unfolding are turned round is mutually interference-free.
Further, the sleeve screw nut structure identical with stayed pole setting.
Further, putting hole is turned round in setting rotation folding and unfolding in the sleeve wall, the rotation folding and unfolding turn round setting handling section and
Silk section, handling section are arranged and on the outside of sleeve, the setting of silk section and sleeve inside.
Further, the domatic protrusion also set in silk section for preventing rotation folding and unfolding from turning round abjection.The slope row protrusion is prevented spin-ended
Turn folding and unfolding torsion from sleeve wall to deviate from.
Further, it also sets up the brake for preventing rotation folding and unfolding torsion dynamic and stops structure.When jaw face needs clamping tissue, need to consolidate
Determine the position and structure of each section, the reversing that will prevent rotation folding and unfolding from turning round at this time, setting brake, which stops structure, can play above-mentioned mesh
's.It is the barrier sheet being arranged outside sleeve that further brake, which stops structure, which connect with extended bar, and extended bar is arranged
Extended bar putting hole is set in the section of stretching out in sleeve wall, in section of stretching out.
Further, the bending drawing silk, rotation folding and unfolding torsion be correspondingly arranged it is multigroup, wherein being preferable to provide to be correspondingly arranged
Two groups, and two groups are arranged in 180 °.It is pliable that such setting can select immediate one group of structure to make after reaching designated position
Tune bends.
Entered by body cavities or scope cavity when use, after reaching at clamping tissue, adjustment rotation folding and unfolding is turned round, and
Turnbarrel, when jaw face clamping tissue, by brake stop structure push, by rotate stayed pole clamping tissue, after brake is stopped
Structure is lifted, and adjustment rotation folding and unfolding is turned round, and takes out biopsy forceps after keeping sheath straight, sample is put into specified containers and is identified, complete
At the use of total.
Compared with prior art, the biopsy forceps of the utility model angle adjustable can be effectively according to the position for needing clamping tissue
It sets and carries out angle adjustment, reach specified angle, designated position.
