Abstract
The utility model discloses a ring cutting suction type parenchyma biopsy sampling probe, which belongs to the medical appliance field and consists of a puncture needle (1), a needle bed (2) and a push-pull lever (6). The ring cutting suction type parenchyma biopsy sampling probe is characterized in that the inner part of a cavity of the puncture needle (1) is provided with a ring cutting knife (4), the upper end edge of the ring cutting knife (4) is fixed with a ring cutting knife pressure lever (5), the upper end of the ring cutting knife pressure lever (5) is fixed on the edge of a sealing plate (9), the middle part of the sealing plate (9) is fixed with the push-pull lever (6), the lateral wall of upper part of the puncture needle (1) is provided with a pumping nozzle (7) which is communicated with a pumping sac (10) by a conduit (8). The ring cutting suction type parenchyma biopsy sampling probe has simple structure, convenient operation and big sampling block, can sample for a plurality of times according to needs, relives the pain of a patient, saves the treatment cost, improves the working efficiency of the medical operator and can be widely applied to the parenchyma biopsy sampling.
Description
Technical field
This utility model relates to a kind of improvement of biopsy sampling probe, specifically a kind of ring cutting suction-type soft tissue biopsy sampling probe.
Background technology
In hospital clinical, in order to determine the character of pathological changes, often need the biopsy of taking a sample of intravital tissue, at present, the method that sampling is adopted to pathological tissue has two kinds: the one, adopt surgical openings 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 have certain deficiency, for surgical openings, main deficiency is: the surgical openings wound area is bigger, and the patient suffering is big, and expense is higher; For taking the puncture needle sampling, because needle tubing is thinner, what adopt in needle tubing is the rotary-cut cutter, by rotary-cut the histiocyte that cuts down is taken out, therefore, it is little to take a sample, sampling amount is few, does not reach the needs of chemical examination sometimes, has then increased patient's misery if go to puncture again.
Summary of the invention
The purpose of this utility model be to provide a kind of not only simple in structure, wound surface is little, and can increase the ring cutting suction-type soft tissue biopsy sampling probe of sampling amount according to the chemical examination needs.
For reaching above purpose, the technical scheme that this utility model adopted is: this ring cutting suction-type soft tissue biopsy sampling probe, by puncture needle, needle stand, push-pull handle constitutes, on the sidewall of the bottom of puncture needle, be provided with the soft tissue inlet hole, the rear end of puncture needle is fixed with being threaded and is gone up needle stand, after sampling is finished, back out needle stand, pulling out push-pull handle takes out institute's sample thief, it is characterized in that being provided with circular cutter at the intracavity of puncture needle, the fixing circular cutter depression bar of going up on the edge, upper end of circular cutter, the upper end of circular cutter depression bar be fixed on sealing plate on the edge, sealing plate the middle part fixing on push-pull handle, on the upper portion side wall of puncture needle, establish the mouth of bleeding, the mouth of bleeding is connected with the capsule of bleeding by conduit, suction by the capsule of bleeding makes the puncture needle intracavity form certain negative pressure, after puncture needle thrusts sampling point, the tissue at soft tissue suction inlet place is sucked the puncture needle intracavity, the reuse push-pull handle pushes circular cutter, cut and organize, being organized in of downcutting is inhaled into the puncture needle intracavity under the suction function, in order to satisfy the chemical examination requirement, as the more tissue of needs cutting, rotatable puncture needle, make to organize and be inhaled into the puncture needle intracavity again, cut, at this moment, the preceding once tissue of cutting is inhaled into the top of circular cutter again, repetitive operation then can be satisfied the requirement of sampling amount.This utility model is also implemented by following measure: described circular cutter is circular, its diameter is consistent with the intracavity diameter of puncture needle, the circular cutter depression bar is established three, on equidistant upper edge that is fixed on circular cutter, the circular cutter depression bar is the bar shaped lamellar, the upper edge consistency of thickness of thickness and circular cutter.When using this utility model, aim at the site of puncture, the acupuncture of will puncturing is pushed the capsule of bleeding to sampling point, to organize and suck the puncture needle intracavity, after the circular cutter cutting, under suction function, the tissue after the separation is inhaled into the puncture needle intracavity, as the more sampling amount of need, as long as rotate puncture needle, repetitive operation gets final product, and can take a sample according to the needed sampling amount of chemical examination.
The beneficial effects of the utility model are: compare with the sampling puncture needle of present employing, and not only simple in structure, easy to operate, and also the sampling piece is big, and can repeatedly take a sample as required, alleviate patient's misery, saved medical expense, also improved worker's work efficiency simultaneously.
