Abstract
The utility model relates to a medical instrument and discloses a novel kidney puncture needle. A slide needle handle is sleeved on a puncture needle body; the slide needle handle is provided with a positioning screw; a scale is arranged at the middle back section of the puncture needle body; and a closed air chamber is arranged in the puncture needle body. According to the novel kidney puncture needle disclosed by the utility model, a puncture depth doses not need to be measured repeatedly and the novel kidney puncture needle can be obviously distinguished from human body tissues; and the novel kidney puncture needle has the advantages of simple structure, convenience for operation and obvious practical applicability.
Description
Technical field
This utility model belongs to technical field of medical instruments, discloses a kind of novel kidney puncture needle.
Background technology
The renal puncture biopsy is a kind of important method of Diagnosis of Renal disease, and when using present kidney puncture needle to puncture, depth of needle will be used ruler measurement repeatedly, and operation is trouble comparatively, and paracentesis depth is not easy to grasp; In addition, under the situation that adopts ultrasonic leading, the projection of puncture needle under ultrasound wave is unintelligible, is difficult to distinguish with tissue, causes puncture position to be difficult to confirm, has also increased certain burden to medical work.
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, easy localized novel kidney puncture needle during puncture.
For realizing above-mentioned technical purpose; This utility model is to adopt following technical scheme to realize: a kind of novel kidney puncture needle, comprise a puncture needle body, and it is characterized in that: be with the slip needle handle on the puncture needle body; The slip needle handle is provided with set screw, and the posterior segment of puncture needle body is provided with scale; Be provided with a closed air chamber in the puncture needle body.
The utlity model has following beneficial effect: the length through the forward puncture needle of slip needle handle scalable stretches out need not measurement paracentesis depth back and forth in piercing process; Because scale is arranged on the puncture needle posterior segment, is with graduated part outside human body, the resistance in the time of can not increasing puncture; And the existence of air chamber can guarantee under the ultrasound wave projection, can obviously distinguish with tissue, more the position that reaches of easy master puncture needle.It is simple in structure, and is easy to operate, has significant practicality.
