Description

Needle handle sleeve for bone puncture needle

Technical field

The utility model belongs to medical device technical field, specifically, being related to a kind of needle handle sleeve for bone puncture needle.

Background technique

Medullo-puncture needle, also referred to as marrow puncture needle are a kind of puncture needles for being used clinically for bone marrow extraction sample survey.At present The structure of clinically used all-metal medullo-puncture needle can be divided into needle handle and needle body two parts, needle handle be sequentially connected by following each section and Composition, including preceding power piece, adjust spiral, fixed spiral, needle body cap and needle core cap totally five parts.The front end of needle body is needle point, The rear end of needle body passes through preceding power piece, adjusts spiral and the centre bore of fixed spiral, is fixedly connected on the centre bore of needle body cap.Before Power piece is an oval laminated structure, and preceding power piece centre bore is located at the center of ellipse and communicates with the centre bore for adjusting spiral. Adjusting spiral is cylindrical body, and front end is fixedly connected with preceding power piece.Moving in rotation adjusts the length that needle body is adjusted in spiral, that is, adjusts The depth punctured is saved, the length of needle handle also has corresponding variation therewith at the same time.Fixed spiral is lug, and rotation is fixed Spiral simultaneously reaches fixed function against spiral is adjusted.Needle body cap is " dry " type structure, and top and centre are ellipse. Medullo-puncture needle needle body be it is hollow, needle core then covers in the cavity of needle body.The front end of needle core is that pointed and with needle body needle point is common The needle point of medullo-puncture needle is formed, the rear end of needle core is fixedly connected with needle core cap.Needle core cap is located at needle handle rear end, by with needle body cap It connects and fixes needle core.Needle core cap is " work " type structure, and both ends are circle.When being punctured, turn adjusts spiral for needle Body is adjusted to certain length and the fixed spiral of turn is fixed, and by the point of puncture of tip alignment bone and uses hand with needle handle is held Power on piece before finger is withstood on, appropriate rotation firmly puncture and reach predetermined depth, the needle core cap positioned at needle handle rear end is first pinched with hand And needle core is extracted, then the centre bore bone marrow extraction sample of needle body cap is connected with syringe.Due to current clinically used all-metal The needle handle of medullo-puncture needle is relatively thin, shorter, and inconvenience is held and exerts oneself.Due to adjusting spiral, fixation in the various pieces of composition needle handle Three parts of spiral and needle core cap are all likely to occur activity when holding needle handle operation, and the activity of any a part all can be to wearing Thorn impacts, and is especially located at the needle core cap of needle handle rear end, it is easy to be touched and lead to the displacement of needle core or even fall off, make At the failure or pollution of puncture.

Chinese utility model patent specification CN202665583U discloses a kind of needle handle sleeve for bone puncture needle.Needle handle set set It is set as the hollow structure inside of front opening, needle handle can be sleeved in the cavity of needle handle set inner hollow, and the length of cavity Greater than the length of needle handle；Cavity Inner Front End, which is placed, to be adjusted the shape of spiral and fixation spiral position and the adjusting spiral of needle handle and consolidates The shape for determining spiral is consistent；The shape that needle body cap position is placed in cavity is the cylinder of ellipsoidal cross section, and elliptic cross-section Major diameter and minor axis it is consistent with needle body cap ellipse；The shape that needle core cap position is placed in cavity is the rounded column in section Body, and the circle of the diameter of circular cross-section and needle core cap is consistent；The length at two positions of needle body cap and needle core cap is placed in cavity It is all larger than the length of needle body cap and needle core cap；A groove, the width and long and needle of groove are provided at the front opening of needle handle set The minor axis of power piece is consistent with major diameter before the ellipse of handle front end.

Solving the problems, such as that needle core cap is easy to be touched in above-mentioned needle handle sleeve for bone puncture needle causes needle core displacement even to fall off, In the operation of actual implementation bone marrow aspiration, it is still necessary to just can be carried out subsequent extraction needle core after first dismantling needle handle sleeve for bone puncture needle, extract The operation of bone marrow specimens is not very convenient；In addition, above-mentioned needle handle sleeve for bone puncture needle is convenient for holding by ergonomic designs, But anti-skidding processing is not carried out to outer surface, can not will be implemented in puncturing operation because risk caused by rubber sleeve minimizes.
