Description
Technical field
The present invention relates to Microendoscopic medical instruments field, more particularly to a kind of biopsy forceps with measuring piece.
Background technology
Endoscopy uses more and more extensive, biopsy as a kind of method of auxiliary diagnosis in clinical medicine inspection
Pincers can be stretched into patient body by endoscope channel, and diseased region is checked, grip pathological tissues.In clinical practice
In, scope doctor is mostly that the size of focus is estimated according to clinical experience, can not accurately measure the size of focus.Application
Numbers 201420596758.1 application documents disclose a kind of biopsy forceps, and the principle of the biopsy forceps is that corresponding survey is set in clamp
Silk is measured, measurement silk is distributed along clamp；The biopsy forceps is used for the diameter for measuring tracheae.But technology disclosed above can not be surveyed
The size of focus is measured, and when sliding the sliding block of biopsy forceps, the distance of operator's sliding slider can not be reminded.
The content of the invention
For technical problem present in prior art, the purpose of the present invention is：A kind of biopsy with measuring piece is provided
Pincers, this biopsy forceps is simple to operate, and the size of the measurable focus to be sampled.
In order to achieve the above object, the present invention is adopted the following technical scheme that：
A kind of biopsy forceps with measuring piece, including hard handle, steel wire tube, binding clip, the first slide fastener, the second slide fastener and survey
Part is measured, described hard handle, steel wire tube, binding clip connect successively, and the first slide fastener is slidably mounted on hard handle, and is passed through
First steel wire is connected with binding clip, and the second slide fastener is slidably mounted on hard handle, and control measuring piece stretches out or the steel of retracting
Second slide fastener of fiber tube is connected by the second steel wire with measuring piece.After this structure, after the first slide fastener control binding clip opens,
Second slide fastener controls the movement of measuring piece, and focus can be measured.
Binding clip includes the upper clamp and lower clamp being hinged, and described measuring piece is in closed, along closing for measuring piece
Combining line, measuring piece runs through upper clamp and lower clamp.After this structure, measuring piece is entered by the hole of upper clamp and lower clamp
Row stretches out or retraction steel wire tube, so as to be measured to focus.
Upper clamp includes upper clamp and the upper plier handle that is wholely set with upper clamp, described lower clamp include lower clamp and with
The lower plier handle that lower clamp is wholely set；Described upper clamp and lower clamp are hinged by clamping axle, described upper clamp, lower clamp and
Described upper plier handle, lower plier handle separation pincers axle both sides；In terms of the axial direction of pincers axle, described measuring piece surrounds pincers axle and run through
Upper clamp and lower clamp.After this structure, the opening and closing of upper plier handle and lower plier handle can control clamp and lower pincers
The opening and closing of folder, measuring piece is stretched out or retracted steel wire tube by the hole of upper clamp and lower clamp, so as to enter to focus
Row measurement.
It is conformed with the inner surface of second slide fastener, the circumference side of the hard handle contacted with the inner surface of the second slide fastener
Provided with groove circumferentially, described projection is adapted with described groove；Described groove is along hard handle
Axial direction be uniformly arranged.After this structure, operator has pause and transition in rhythm or melody sense when sliding the second slide fastener, reminds operator to slide
The depth of dynamic second slide fastener.
Measuring piece is in the kidney-shaped of closed；One side of described measuring piece sets the wide projections of 1mm at interval of 0.25cm；Institute
The middle part of the another side for the measuring piece stated sets the wide projections of 1mm at interval of 1mm, and the projection on the side has 5.Using this structure
Afterwards, it is convenient for measuring the projection set in the middle part of the size of focus, the another side of measuring piece and is convenient for measuring the focus that size is less than 1cm.
Measuring piece is in the kidney-shaped of closed；One side of described measuring piece sets the wide blue colors of 1mm at interval of 0.25cm
Block, it is 1cm and spaced blue color lump and black color lump that the middle part of the another side of described measuring piece, which sets beam overall, described
Blue color lump and the width of black color lump be 1mm.After this structure, the size of focus is convenient for measuring, meanwhile, measurement
When part is located in human body, blue color lump and black color lump is easily recognized.
The circumference side of the hard handle contacted with the inner surface of the second slide fastener is provided with scale.After this structure,
Scale on operator's observable hard handle, so as to understand the depth for sliding the second slide fastener.
Steel wire tube is stretched into hard handle, and the end of the steel wire tube stretched into hard handle is wedge shaped, the second described cunning
Detain towards the side of steel wire tube provided with the adaptable voussoir in the wedge-shaped end with steel wire tube, the top of the voussoir is provided with circle
