Abstract
The utility model discloses a nephrology puncture needle. A needle body is a metal tube. A rear end of the needle head is a needle seat. The front end is a needle tip. The wall of the metal tube is closed and of a hollow sandwich structure. Particularly, scales are arranged on the outer wall of the metal tube; and a slidable scale enlargement indicator is sleeved on the metal tube. The nephrology puncture needle has the advantages that since the needle head metal tube is of a hollow sandwich structure, the position of the needle head can be clearly displayed on a B ultrasound screen in a puncture, and puncture error is avoided. With the addition of the needle inserting scale indicator, success probability and safety of the puncture can be increased.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specially a kind of Urology Department puncture needle.
Background technology
Urology Department is a utmost point efficient assistant method of diagnosis kidney disease to the renal puncture biopsy clinically at present, but general hospital Urology Department is not owing to there is suitable puncture needle, and being not easy implements to puncture takes out the operation of kidney biopsy sample.And present operation technique is generally down auxiliary at ultrasonic instrument, assists puncture procedure by the display screen of ultrasonic instrument.But because the puncture needle internal structure, the profile of needle body is not easy to show clearly on ultrasound display screen.
Summary of the invention
Goal of the invention of the present utility model overcomes the prior art deficiency, provides a kind of ultrasound wave screen that is suitable for to show a kind of Urology Department puncture needle that carries out renal puncture under the state, and is safe and reliable, simple to operation.
Technical solution of the present utility model is achieved in that a kind of Urology Department puncture needle, and needle body is metal tube, and the syringe needle rear end is needle holder, and front end is needle point, and the tube wall of described metal tube is the hollow sandwich structure of sealing.
The outer wall of described metal tube is provided with scale, and has slidably scale amplify direction board to be enclosed within on the described metal tube.
Beneficial technical effects of the present utility model is: because the syringe needle metal tube is the hollow sandwich structure, during puncture, can clearly manifest the particular location of syringe needle on the B ultrasonic screen, avoid error.If add the indication of inserting needle scale, can more increase certainty, the safety of puncture.
Description of drawings
Fig. 1 is structure partial generalized section of the present utility model.
Among the figure, 1. needle holder, 2. metal tube, 3. scale amplifies direction board, 4. scale, 5. interlayer cavity, 6. syringe needle puncture chamber, 7. needle point.
The specific embodiment
Below in conjunction with the embodiment that provides in the accompanying drawing, structure of the present utility model and use are elaborated.
A kind of Urology Department puncture needle, needle body are metal tube 2, and the syringe needle rear end is needle holder 1, and front end is needle point 7, and the tube wall of described metal tube 2 is the hollow sandwich structure of sealing; The outer wall of described metal tube 2 is provided with scale 4, and has slidably scale amplify direction board 3 to be enclosed within on the described metal tube, to communicate before and after the inner chamber of metal tube 2, be syringe needle puncture chamber 6, and the interlayer cavity 5 of sealing plays the reflection supersonic wave effect.
Claims (2)
1. Urology Department puncture needle, needle body is metal tube, and the syringe needle rear end is needle holder, and front end is needle point, it is characterized in that the tube wall of described metal tube is the hollow sandwich structure of sealing.
