Abstract
The utility model relates to the technical field of medical instruments, particularly to a multifunctional kidney puncture outfit which is characterized in that a core needle is arranged inside a hollow core needle body; a cone-shaped needlepoint extending out of a needlepoint of the hollow core needle body is arranged at the front end of the core needle; an operating handle is arranged at the back end of the core needle; connecting threads matched with a connecting port of the hollow core needle body are formed in the operating handle; a developer cavity is formed in the front end of the core needle; and a mouth of the developer cavity is arranged on the front end wall of the core needle, and is plugged by a medical rubber plug. During the use, the core needle is inserted into the hollow core needle body; the operating handle of the core needle and the connecting port of the hollow core needle body are connected; the cone-shaped needlepoint at the front end of the core needle extends out of the hollow core needle body to facilitate puncture operation and improve the accuracy of biopsy sampling; further, an injector penetrates through the medical rubber plug of the mouth of the developer cavity to inject developer to guide operation through type-B ultrasonic; and the hollow core needle body can be fixed inside the body of a patient through a positioning tray. Therefore, the multifunctional kidney puncture outfit has the advantages that the operation is convenient, the use is safe, the biopsy sampling effect is excellent, and the like.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of easy to operate, safe in utilization, multi-functional kidney puncture needle.
Background technology
As everyone knows, thoracentesis needle commonly used is that an employing rustless steel is made long, thicker hollow needle body, the front end of hollow needle body is provided with needle point, the rear end of hollow needle body is provided with the connector that links to each other with syringe or negtive-pressure implement, during use, point of puncture to the patient carries out local anesthesia earlier, needle point with needle body vertically thrusts in patient's body again, connector connects syringe or negtive-pressure implement then, in patient's body, inject medicinal liquid, or intravital gas of patient or liquid aspirated, the weak point of this puncture needle is: the one, and the aperture of needle point is bigger, easy damaged patient's intercostal blood vessel not only, nerve and viscera tissue, and in piercing process the pin hole of puncture needle front end in piercing process easily by skin, muscle blocks, and the biopsy sampling is inaccurate; The 2nd, operating difficulties, the depth of needle of puncture needle is wayward, thrusts back hollow needle body and is difficult for fixing; The 3rd, this puncture needle can not carry out catheter drainage, can not implement the anesthesia art to internal organs, has increased pain to the patient, easily causes patient's pachynsis pleurae adhesion.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of easy to operate, safe in utilization, multiple functional, effective multi-functional kidney puncture needle is provided.
This utility model can reach by following measure:
A kind of multi-functional kidney puncture needle, be provided with the hollow needle body, the front end of hollow needle body is provided with needle point, the rear end of hollow needle body is provided with the connector that links to each other with syringe or negtive-pressure implement, it is characterized in that being provided with in the hollow needle body core pin, core pin front end is provided with the taper needle point that stretches out hollow needle body needle point, the rear end of core pin is provided with lever, lever is provided with the connecting thread that matches with hollow needle body connector, core pin front end is provided with the developing agent chamber, the developing agent accent is located on the core pin front bulkhead, and the developing agent accent is stopped up by the medical grade rubber plug.
This utility model can be with positioning disk on the hollow needle body, positioning disk is provided with positioning sleeve, and positioning sleeve is provided with bolt, and the bolt by positioning sleeve can be fixed on positioning disk on the hollow needle body.
When this utility model uses, the core pin inserted in the hollow needle body and the lever of core pin is connected with the connector of hollow needle body, make the taper needle point of the front end of core pin stretch out the hollow needle body, to make things convenient for puncture procedure, improve the accuracy of biopsy sampling, the reuse syringe passes the medical grade rubber plug injection developing agent of developing agent accent, to guide operation by B ultrasonic, the hollow needle body can be fixed in patient's body by positioning disk, have advantages such as operation side makes, safe in utilization, biopsy sampling is effective.
