Abstract
The utility model relates to the technical field of medical apparatuses, in particular to a novel anesthetizing and puncturing needle for sampling a biopsy specimen. The novel anesthetizing and puncturing needle for sampling the biopsy specimen comprises a needle tube, a puncture needle, an anesthetizing needle and a liquid storage cavity, wherein a piston is arranged inside the needle tube; the puncture needle is connected with the front end of the needle tube; a finger handle is arranged at the back end of the needle tube; the anesthetizing needle is arranged inside the puncture needle; a piston rod is arranged at the back end of the piston; the anesthetizing needle is communicated with the liquid storage cavity; and a silica gel plug and a one-way valve are arranged on the liquid storage cavity. The novel anesthetizing and puncturing needle for sampling the biopsy specimen is novel in design; an independent anesthetizing agent passage is arranged in the inner cavity of the puncture needle, so that in the biopsy specimen sampling process, the operation is easy and convenient, pains of a patient are reduced and the working difficulty of the medical staff is reduced.
Description
Technical field
This utility model relates to medical instruments field, and especially a kind of novel biopsy sample extracts anaesthetic puncture needle.
Background technology
At present; when carrying out the biopsy sampling operation clinically; apparatus used mostly is greatly common vacuum injector; the characteristic of biopsy sampling; can cause great misery to the patient when having determined the extraction biological tissue, the doctor can give patient infusion anesthetis usually, and needs of patients bears twice acupuncture; this operational approach bothers very much, has increased great work difficulty to the medical worker.
The utility model content
The purpose of this utility model is to provide a kind of novel biopsy sample to extract anaesthetic puncture needle in order to overcome above-mentioned technical disadvantages.
The technical scheme that this utility model technical solution problem adopts is: a kind of novel biopsy sample extracts anaesthetic puncture needle, comprise syringe, puncture needle, anesthetic needle and liquid storage cylinder, be provided with piston in described syringe, syringe front end connecting puncture needle, the rear end is provided with dactylostyle, is provided with anesthetic needle in described puncture needle, and piston rear end is provided with stopper rod, described anesthetic needle is communicated with liquid storage cylinder, and described liquid storage cylinder is provided with silica gel plug and check valve.
Described liquid storage cylinder is located at the syringe interior forward end and is fixedly connected with syringe, and it is outside and be provided with silica gel plug that the opening of liquid storage cylinder is located at syringe, and described check valve is located at liquid storage cylinder and is positioned on syringe side partly.
The beneficial effect that this utility model has is: this utility model is novel in design, and independently anesthetis passage is set in the inner chamber of puncture needle, and is easy and simple to handle when carrying out the biopsy sample extraction, alleviated patient's misery, reduced medical worker's work difficulty.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
Do following detailed description below in conjunction with 1 pair of this utility model of accompanying drawing.
As shown in Figure 1, this utility model comprises syringe 1, puncture needle 2, anesthetic needle 3 and liquid storage cylinder 5, be provided with piston 4 in described syringe 1, syringe 1 front end connecting puncture needle 2, the rear end is provided with dactylostyle 9, is provided with anesthetic needle 3 in described puncture needle 2, and piston 4 rear ends are provided with stopper rod 8, described anesthetic needle 3 is communicated with liquid storage cylinder 5, and described liquid storage cylinder 5 is provided with silica gel plug 6 and check valve 7; Described liquid storage cylinder 5 is located at syringe 1 interior forward end and is fixedly connected with syringe 1, and it is outside and be provided with silica gel plug 6 that the opening of liquid storage cylinder 5 is located at syringe 1, and described check valve 7 is located on the side that liquid storage cylinder 5 is positioned at syringe 1 part.During use, anesthetis injects liquid storage cylinder 5, and puncture needle 2 thrusts the backward front promotion stopper rod 8 of body, and anesthetis is injected body, and during sample drawn, under the effect of check valve 7, anesthetic needle 3 pipe sealings avoid tissue samples to enter anesthetic needle 3.
