The disposable scissor biopsy needle that body tissue and liquid tissue are sampled, belongs to technical field of medical instruments.
Background technology
Biopsy needle is that one kind is widely used in entering the solid tissues such as testis, muscle, liver, superficial tumor and liquid tissue
The medicine equipment of row sampling.Clinically when being checked for tumour patient, in order to determine tumour property, it is necessary to biopsy needle from
Disease sites take out some living tissues and tested.Current clinical hospitals typically take negative pressure biopsy needle to be sampled, and such as apply
Number be CN02276714.2, it is entitled《Disposable negative pressure biopsy needle》Chinese patent disclosed in biopsy needle.This work
Inspection pin carries the biopsy nook closing member of solid piercing needle provided with coaxial trochar and front end, forms the inside and outside outer pin being socketed and interior
Biopsy window is offered on pin, outer pin and interior pin respectively, two longitudinal edges of biopsy window are shearing edge, when biopsy, will be cased with outer
The interior pin of pin penetrates tissue, by negative pressure by it is to be checked tissue suck biopsy window in, pin in turn, using interior pin shearing edge and
Relative turn between the shearing edge of outer pin forms shearing, and then obtains required biological tissue.But such biopsy needle is deposited
The problem of be：Because the shearing edge of outer pin and interior pin is horizontal flat edge, two cutting edges are formed in relative turn and sheared
When belong to monoblock type truncation, shearing difficulty is big, easily causes that sampling is difficult, and wound face is big, and can not grasp sampling well
Amount.
Utility model content
In order to solve the above problems, the utility model provides a kind of disposable scissor biopsy needle, the biopsy needle
, being capable of picture when the cutting edge of outer pin and interior pin is with respect to turn by the way that the cutting edge port on outer pin and interior pin is designed into declivous cutting edge
Scissors equally carries out cross-cut, therefore sampling block to tissue, and wound face is small.
The concrete technical scheme that the utility model is used is as follows：
A kind of disposable scissor biopsy needle, including the outer pin and interior pin being coaxially socketed, outer pin and interior pin are equipped with
Needle tubing and needle stand；The front end of the outer pin needle tubing is opening, and outer pin needle tubing is provided with outer elongated slot from front end along body and made backward
For outer biopsy window, two longitudinal edges of outer elongated slot are low early and high after hypotenuse, and it is used as outer pin cutting edge port；Before the interior pin needle tubing
Termination is solid piercing needle, and interior pin needle tubing is provided with interior elongated slot at the rear of front end as interior biopsy window backward along body, interior
Two longitudinal edges of elongated slot are low early and high after hypotenuse, and it is used as interior pin cutting edge port；The interior pin needle stand pivot bush unit is in outer pin pin
In seat, interior pin needle tubing pivot bush unit is in outer pin needle tubing and the internal diameter of the external diameter of interior pin needle tubing and outer pin needle tubing fits, interior pin
The front end of needle tubing is stretched out outside the front end of outer pin needle tubing, the outer biopsy window of outer pin needle tubing and the interior biopsy window of interior pin needle tubing
Position is corresponding, when outer pin needle tubing rotates relative to interior pin needle tubing, outer pin cutting edge port and interior pin cutting edge port formation scissors
Formula is intersected.
For the ease of insertion tissue, the front and rear widthwise edge of the interior biopsy window of the interior pin needle tubing is sweptback tiltedly for upper end
The arc-shaped side to be formed is cut in face, and the rear horizontal edge of the outer biopsy window of the outer pin needle tubing cuts to be formed for the sweptback inclined-plane in upper end
Arc-shaped side.Further, the open edge of the outer pin needle tubing front end is additionally provided with chamfering.
Advantage of the present utility model is：This biopsy needle by the way that the cutting edge port on outer pin and interior pin is designed into declivous cutting edge,
In use, will be first punctured to after the interior biopsy window alignment of the outer biopsy window of the outer pin of this biopsy needle and interior pin in tissue, then pass through
Outer pin needle stand rotates outer pin, outer pin cutting edge port and interior pin cutting edge port is formed scissor cutting, realizes to tissue
Fast sampling, therefore compared with common flat edge biopsy needle, this biopsy needle is fast using scissor cutting sampling, wound
Face is small, and sampling amount can be grasped well.
