Abstract
The utility model relates to a kidney biopsy puncture needle which comprises a puncture needle tube. Scale marks are evenly arranged on the surface of the puncture needle tube. A conic needle base is arranged at the rear end of the puncture needle tube, the rear end of the puncture needle tube is connected with a combination part of the front end of a needle cylinder, a pushing rod is arranged in the needle cylinder, and the front end of the pushing rod is provided with a rubber head connected with a needle cylinder piston. Due to the fact that a sealing cavity filled with water is arranged on the inner tube wall of the puncture needle tube, water is an even medium, and reflection of ultrasonic waves is avoided when the ultrasonic waves are transmitted in water, a good sound permeating window can be formed, a boundary of the puncture needle and the kidney and boundaries of the puncture needle and the surrounding tissues are clear, and medical staff can accurately master the needle entering condition. A filter screen is arranged on the portion, close to a front end needle tip, in the puncture needle tube, so that the puncture needle is prevented from being blocked by particles in the kidney and the working difficulty of the medical staff is relieved. The scale marks are arranged on the surface of the puncture needle tube so that the puncturing depth can be accurately controlled, use can be convenient, and the success rate of the biopsy puncture is high.
Description
Technical field
This utility model relates to technical field of medical instruments, relates in particular to a kind of kidney biopsy puncture needle.
Background technology
In Urology Department diagnosis and treatment process, renal puncture biopsy is a kind of method that judges nephropathy type.When renal puncture biopsy, need to use puncture needle, and existing puncture needle is because reasons in structure exists kidney and the surrounding tissue unclear problem of demarcating in the time that biopsy shows, and then affect doctor diagnosed, and puncture needle some solid particles in puncture tends to by kidney when human kidney stop up, the carrying out and the puncture effect that affect kidney puncture, increased great work difficulty to medical worker, is difficult to guarantee primary sample success, Biopsy efficiency is low, inconvenient operation.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of kidney biopsy puncture needle is provided, and in the time that biopsy shows, kidney and surrounding tissue boundary are clear, when puncture, avoid puncture needle blocked, can accurately control paracentesis depth, easy to use, Biopsy success rate is high.
This utility model is achieved through the following technical solutions: a kind of kidney biopsy puncture needle, comprise puncture needle tubing, described puncture needle tube-surface is evenly provided with graduation mark, described puncture syringe rear end arranges tapered needle seat, described puncture syringe rear end is connected with syringe front end joint portion, in described syringe, be provided with push rod, described push rod front end is provided with the Rubber end being connected with cylinder piston.
On described puncture needle tubing inner tubal wall, be evenly provided with several seal chambers, in described seal chamber, be full of water.
In the needle tubing of the forward end needle point of described puncture needle tubing, be provided with drainage screen.
Described tapered needle seat rearward end is provided with the pipeline section that is connected of pegging graft with joint portion.
Compared with prior art, the beneficial effects of the utility model are: this utility model by arranging water-filled seal chamber on puncture needle tubing inner tubal wall, simultaneously because water is a kind of uniform dielectric, ultrasound wave does not reflect in the time of water transmission, can form good sound transmitting window, and then make puncture needle and kidney and surrounding tissue boundary clear, be conducive to medical worker and accurately grasp inserting needle situation, improve work efficiency, by drainage screen being set in the needle tubing of the forward end needle point of puncture needle tubing, can avoid puncture needle to be stopped up by the particulate matter in kidney, alleviate medical worker's work difficulty, by graduation mark being set at puncture needle tube-surface, can accurately control paracentesis depth, easy to use, Biopsy success rate is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of kidney biopsy puncture needle of this utility model;
Fig. 2 is the front view of this utility model puncture needle tubing.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, and be not used in restriction this utility model.
As shown in Figure 1-2, this utility model relates to a kind of kidney biopsy puncture needle, comprise puncture needle tubing 1, described puncture needle tubing 1 surface uniform is provided with graduation mark 2, described puncture needle tubing 1 rear end arranges tapered needle seat 3, described puncture needle tubing 1 rear end is connected with syringe 5 front end joint portions 4, in described syringe 5, be provided with push rod 7, described push rod 7 front ends are provided with the Rubber end 6 being connected with syringe 5 pistons, on described puncture needle tubing 1 inner tubal wall, be evenly provided with several seal chambers 9, in described seal chamber 9, be full of water, in the needle tubing of the forward end needle point of described puncture needle tubing 1, be provided with drainage screen 8, described tapered needle seat 3 rearward end be provided with peg graft with joint portion 4 be connected pipeline section 10.
In sum, this utility model by arranging water-filled seal chamber 9 on puncture needle tubing 1 inner tubal wall, simultaneously because water is a kind of uniform dielectric, ultrasound wave does not reflect in the time of water transmission, can form good sound transmitting window, and then make puncture needle and kidney and surrounding tissue boundary clear, be conducive to medical worker and accurately grasp inserting needle situation, improve work efficiency, by drainage screen 8 being set in the needle tubing of the forward end needle point of puncture needle tubing 1, can avoid puncture needle to be stopped up by the particulate matter in kidney, alleviate medical worker's work difficulty, by graduation mark 2 being set on puncture needle tubing 1 surface, can accurately control paracentesis depth, easy to use, Biopsy success rate is high.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
