Abstract
The utility model belongs to medical apparatus and instruments and discloses a kidney puncture needle. The kidney puncture needle comprises a needle body and is characterized in that the needle body comprises a solid section, an elliptical tube section and a round tube section from the front to the rear; a wedged tip end is formed at the front end of the solid section; longitudinal sampling ports are formed in two side walls, corresponding to a long axis of an elliptical cross section, of the elliptical tube section; and edges on two sides of each sampling port are blade surfaces. The needle body is thin, the puncture is easy, and the trauma is small; and the sampling ports are located on an elliptical tube, so that when the needle body is rotated, kidney tissues can be cut by the aid of the blade surfaces of the sampling ports, and accordingly biopsy sampling is completed.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of kidney puncture needle.
Background technology
The kidney puncture needle that uses mostly adopts the combinative structure of sleeve pipe, nook closing member at present, and needle body is thicker, and wound is big during puncture, and can not guarantee the primary sample success, and operation is trouble rather.The kidney puncture needle of mentioning in some scheme is to have breach at the needle body sidewall, rotatable needle body obtains tissue sample by breach, because its needle body cross section is circular, be difficult to also during rotation guarantee that breach can cut to tissue sample smoothly, so biopsy puncture efficient is low, use to have certain inconvenience.
The utility model content
For overcoming above-mentioned technical problem, it is a kind of simple in structure, easy to operate that this utility model provides, and the puncture wound is little, the kidney puncture needle that the biopsy sampling efficiency is high.
For realizing above-mentioned technical purpose, this utility model adopts following scheme: a kind of kidney puncture needle, comprise a needle body, and it is characterized in that: be followed successively by solid section, oval pipeline section and pipe section before and after the needle body, solid section front end is provided with wedge shaped tip; Oval pipeline section has sample tap longitudinally in the corresponding two side of oval cross section major axis, and the edge of sample tap both sides is the sword face.
The utlity model has following beneficial effect: it need not to cooperate sleeve pipe to use, and needle body is thin, puncture easily, and wound is little; Because the sample tap position is elliptical tube, sample tap can cut kidney portion tissue by the sword face during rotation needle body, finishes the biopsy sampling.
Description of drawings
Fig. 1 is this utility model structural representation.
Among the figure, 1, wedge shaped tip, 2, sample tap, 3, the sword face, 4, the pipe section, 5, oval pipeline section, 6, solid section.
The specific embodiment
Referring to shown in Figure 1, be followed successively by solid section 6, oval pipeline section 5 and pipe section 4 before and after the needle body, solid section 6 front end is provided with wedge shaped tip 1; Oval pipeline section 5 has sample tap 2 longitudinally in the corresponding two side of oval cross section major axis, and the edge of sample tap 2 both sides is sword face 3.
