Abstract
The utility model relates to a novel marrow puncture needle, consisting of a needle core (1) and a sleeve needle (2). Before puncturing, the needle core (1) rotates on the sleeve needle (2), so that ascrew (7) arranged between the needle core seat (4) and the sleeve needle seat (6) is screwed well; and the pinhead of the needle core is jointed with the pinhead (5) of the sleeve needle well. On the basis of puncturing, the depth adjusting pole of the sleeve needle (2) is fixed on the proper mark (8) of the sleeve needle body. When puncturing, the puncture needle is hold by a hand, and the prismatoidal pinhead (3) is contacted with the puncturing part and is vertical to the bone surface for screwing into in a way of rotating from the left to the right. After the puncture needle is fixed, the screw (7) arranged between the needle core seat (4) and the sleeve needle seat (6) is reversely, the needle core (1) is pulled out; then a 20 ml syringe is used for aspiration; after finishing the aspiration, the needle core (1) is inserted and the puncture needle is pulled out.
Description
Technical field
This utility model relates to medical instruments field, is a kind of novel marrow puncture needle.
Background technology
Marrow puncture needle commonly used at present, the syringe needle of nook closing member is an inclined-plane, is difficult for transdermal and sclerotin; And in piercing process usually the nook closing member slippage can appear, cause trocar to block and cause puncture failure.Depth of needle generally about 1.5cm, did not have scale on the existing puncture needle trocar when adult punctured in the ilium site of puncture, and the degree of depth of inserting needle is difficult for grasping.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, to provide a kind of and can be beneficial to the marrow puncture needle that transdermal enters sclerotin, prevents the nook closing member slippage.
The technical solution of the utility model is: a kind of marrow puncture needle, form by nook closing member and trocar.The syringe needle that it is characterized in that nook closing member is a prismatic (3); The root of nook closing member has screw (7), has screw to fix between the needle stand of nook closing member and the needle stand of trocar; The needle body of trocar is marked with scale (8).
The utlity model has following advantage: the syringe needle of puncture needle is prismatoidal, is beneficial to pass skin and enter sclerotin; Involutory tight screw is arranged between the needle stand of nook closing member and the needle stand of trocar, be easy to fix, in piercing process, can prevent the nook closing member slippage.Scale is arranged on the trocar, can be as required that the depth adjustment bar is fixing in position before puncture.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Accompanying drawing 1 is the sketch map of this utility model nook closing member.
Accompanying drawing 2 is sketch maps of this utility model trocar.
1. nook closing members among the figure, 2. trocar, the 3. prismatic syringe needle of nook closing member, the 4. needle stand of nook closing member, the 5. syringe needle of trocar, the 6. needle stand of trocar, 7. screw, the 8. scale on the trocar needle body (unit be centimetre).
The specific embodiment
Referring now to accompanying drawing, be described as follows in conjunction with example:
This utility model is made up of accompanying drawing 1 and accompanying drawing 2.Before the puncture, nook closing member (1) rotates in trocar (2), and the screw (7) between nook closing member needle stand (4) and the trocar needle stand (6) is tightened, and the syringe needle of nook closing member (3) is connected with the syringe needle (5) of trocar.And, the depth adjustment bar on the trocar (2) is fixed on the suitable scale of trocar needle body (8) according to the puncture needs.During puncture, hand-held puncture needle, prismatoidal syringe needle (3) contact site of puncture, vertical facial left rotation and right rotation inserting needle.After puncture needle was fixing, the screw (7) between reverse rotation nook closing member needle stand (4) and the trocar needle stand (6) was extracted nook closing member (1) out, uses the 20ml syringe pump, and suction finishes, and inserts nook closing member (1), extracts puncture needle.
