Abstract
The utility model discloses a kidney puncture needle, and relates to the technical field of medical apparatus and instruments. The kidney puncture needle comprises a needle body, a needle point and a circular ring; the needle point of the needle body is conical; the circular ring is fixedly arranged above the needle point; the circular ring is sleeved on the needle body; a fixing sleeve which can slide along the needle body is arranged outside the needle body; the fixing sleeve is provided with a fastening screw; and the needle body is provided with scales. When the kidney puncture needle is used, the scales arranged on the needle body can be read conveniently according to the preset puncture depth, and the fixing sleeve outside the needle body is moved to the scales and is fixed by the fastening screw for operation; and by the mode, the needle insertion depth can be effectively controlled, time and labor are saved, and medical workers can operate the kidney puncture needle conveniently.
Description
Technical field
This utility model relates to the medical device technical field, relates in particular to a kind of kidney puncture needle.
Background technology
The renal puncture biopsy is a kind of important method of Diagnosis of Renal disease; When utilizing kidney puncture needle to carry out the renal puncture biopsy at present clinically, need two people operation, aspirate negative pressure by the assistant; During puncture puncture needle is thrust; Depth of needle will be used ruler measurement repeatedly, makes troubles influence puncture quality to operation.After having measured paracentesis depth during puncture, be fixed on the puncture needle,, move, and influence the accuracy of paracentesis depth but be prone to finger in the operating process to confirm the puncture depth of needle with finger.In addition, common puncture needle is very unintelligible in ultrasonic following projection, is difficult to distinguish with kidney and surrounding tissue, and it is inaccurate that the site of puncture is confirmed, this has just increased work difficulty to the medical personnel.Have the people that existing technology is improved, disclosed by utility model patent Ma Xichen, Tan Yuli design, that the patent No. is 201020604951.7, name is called a kind of novel kidney puncture needle on June 8th, 2011 like State Intellectual Property Office, it comprises needle body for this reason; Needle point and annulus; The needle point of needle body is tapered, is provided with annulus in the needle point upper fixed, and said annulus is enclosed within on the needle body; Annulus is processed by stainless steel material, and annulus inside is filled with air.Under ultrasonic guidance, carry out during use; Because air has intensive reflexive, it is clear with kidney and surrounding tissue boundary on the ultrasonic machine screen to make the needle point top contain the annulus of air, can effectively help the Urology Department doctor to judge the inserting needle situation; Reasonable in design, easy to operate.Its shortcoming is: can't effectively control depth of needle, influence the accuracy of paracentesis depth, be not easy to operation of medical workers.
Summary of the invention
The purpose of this utility model provides a kind of kidney puncture needle that can effectively control depth of needle.
This utility model for realizing the technical scheme that above-mentioned purpose adopted is:
A kind of kidney puncture needle comprises needle body, needle point and annulus; The needle point of needle body is tapered, is provided with annulus in the needle point upper fixed, and said annulus is enclosed within on the needle body; It is characterized in that: being outside equipped with at described needle body can be along the fixed cover of needle body slip, and fixed cover is provided with hold-down screw.Described needle body is provided with scale.
A kind of kidney puncture needle of this utility model; In use according to predetermined paracentesis depth; Can read the scale that is provided with on the needle body easily, the fixed cover that said needle body is outer moves to the scale place and fixedly gets final product operation technique with hold-down screw, adopts this mode can effectively control depth of needle; Time saving and energy saving, make things convenient for medical personnel to operate.
