Abstract
A soft tissue biopsy sampler belongs to medical instrument technical field and is composed of a puncture needle, a needle tube, a negative pressure suction ball, a casing tube and a seal plug, and is characterized in that the negative pressure suction ball is connected with the front side wall of the needle tube, the upper thread of a rubber head is connected with a needle tip, namely the solid puncture needle, and a rectangle suction hole is machined on the needle wall of the rear end of the solid needle tip; the casing tube with a through hole in the middle is provided with a sharp cutting edge on the front end, the rear end is connected with a handle in sealing manner, the front end of the casing tube penetrates through the interior of the rear end of the needle tube to be nested with the seal plug in sliding and seal connection with the outer wall of the casing tube and penetrates through the interior of the puncture needle matched with the casing tube. The utility model has the advantages that: the soft tissue biopsy sampler has simple structure, convenient use and can perform multiple sampling as required, reduces the patient pain, saves treatment cost and improves the work efficiency.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of soft tissue biopsy sampler.
Background technology
At present, the method that sampling is adopted to pathological tissue has two kinds: the one, and adopt operative incision to take out pathological tissues, do the section biopsy; Another kind is the method sampling of adopting puncture.Though more than two kinds of methods can effectively take out sample tissue, also exist certain not enough: when adopting the operative incision sampling, wound area is big, and the patient suffering is big, the expense height; When adopting the piercing method sampling, because needle tubing is thinner, what adopt in the needle tubing is again the rotary-cut cutter, and what cut down organizes little and lack, can not satisfy the chemical examination needs sometimes, needs puncture once more to take a sample, and has increased patient's misery.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of little to patient's wound, as required the soft tissue biopsy sampler of grab sample.
The purpose of this utility model is achieved in that this soft tissue biopsy sampler inhales ball, sleeve pipe, sealing-plug by puncture needle, syringe, negative pressure and form, the syringe front end side wall is connected with negative pressure and inhales ball, the needle point that is being threaded on the nipple is solid puncture needle, has the rectangle inlet hole on the pin wall of solid needle point rear end; The sleeve pipe front end that the middle part is provided with through hole is provided with sharp knife edges, and back-end sealing is connected on the handle, and the sleeve pipe front end passes the puncture needle inside that the inner sealing-plug suit that is connected with the sleeve outer wall slipper seal of back end of syringe adapts with it.
During use, extruding negative pressure suction ball can be drawn into the puncture needle intracavity from suction inlet with soft tissue after puncture needle thrust the site of puncture, promoted sleeve pipe then forward, and the soft tissue that sleeve pipe front end sharp knife edges can will be drawn into the puncture needle intracavity cuts down.As the more tissues of needs cuttings, pull sleeve pipe backward rotates and pushes negative pressure again behind the puncture needle and inhale ball, just tissue is sucked again and promotes sleeve pipe more forward behind the puncture needle chamber and soft tissue can be cut down.
Advantage of the present utility model: simple in structure, easy to use, can repeatedly take a sample as required, can alleviate patient's misery, save medical expense, increase work efficiency.
Description of drawings
Accompanying drawing is a structure cutaway view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: this soft tissue biopsy sampler is made up of puncture needle 1, syringe 2, negative pressure suction ball 3, sleeve pipe 4, sealing-plug 5, syringe 2 front end side wall are connected with negative pressure and inhale ball 3, the needle point that is being threaded on the nipple is solid puncture needle 1, has rectangle inlet hole 6 on the pin wall of solid needle point rear end; Sleeve pipe 4 front ends that the middle part is provided with through hole 7 are provided with sharp knife edges, and back-end sealing is connected on the handle 8, and sleeve pipe 4 front ends pass puncture needle 1 inside that inner sealing-plug 5 suits that are connected with sleeve pipe 4 outer wall slipper seals in syringe 2 rear ends adapt with it.
