Description
Technical field
This utility model relates to a kind of marrow puncture needle.
Background technology
At present, when extracting Bone Marrow of Patients, marrow puncture needle used is smooth periphery syringe needle, when running into the patient that sclerotin is harder, in the time of need to wearing out sclerotin, take very large strength and just can enter medullary cavity, also very difficult while pulling out pin, not only time-consuming but also require great effort, also can cause certain misery to the patient, and owing on existing marrow puncture needle, there is no handle, hand-held very inconvenient, also brought inconvenience to practical operation.
Summary of the invention
For solving above-mentioned existing shortcoming, main purpose of the present utility model is to provide a kind of marrow puncture needle of practicality, can implement fast the bone puncture, easy and simple to handle, time saving and energy saving, alleviate patient's misery, and easily puncture when the harder patient of puncture sclerotin, improve puncture success rate.
For reaching above-described purpose, a kind of marrow puncture needle of the present utility model is taked following technical scheme:
A kind of marrow puncture needle, comprise needle body and nook closing member, it is characterized in that, the front end of described needle body arranges syringe needle, the both sides of needle body arrange handle, and described nook closing member consists of fine needle part and back handle, and the fine needle of nook closing member partly is arranged in the needle body endoporus, the front end of described syringe needle is set to beveled point, and the sharp keen screw wing of projection is set on the cylindrical of syringe needle.
Described needle body middle part is provided with the external screw thread of scale, and described being with on graduated external screw thread arranges clamp nut and adjusting nut.
Adopt as above this utility model of technical scheme, there is following beneficial effect:
Can implement fast bone puncture, easy and simple to handle, time saving and energy saving, alleviate patient's misery, and easily puncture during harder patient at the puncture sclerotin, improve puncture success rate.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is nook closing member structural representation of the present utility model.
The specific embodiment
In order to further illustrate this utility model, below in conjunction with accompanying drawing, further describe:
As shown in Figure 1, a kind of marrow puncture needle of the present utility model, comprise needle body 1 and nook closing member 2, the front end of needle body 1 arranges syringe needle 3, the both sides of needle body 1 arrange handle 4, nook closing member 2 consists of fine needle part and back handle 5, the fine needle of nook closing member 2 partly is arranged in needle body 1 endoporus, the front end of syringe needle 3 is set to beveled point 6, and the sharp keen screw wing 7 of projection is set on the cylindrical of syringe needle 3, when puncture, operator grasps needle body 1 makes its rotation, syringe needle 2, under the effect of sharp keen screw wing 7, just can penetrate Bone Marrow of Patients very easily, operates very laborsaving.Needle body 1 middle part arranges the external screw thread 10 with scale, clamp nut 8 and adjusting nut 9 are set on the external screw thread 10 with scale, adjust the position of adjusting nut 9 on needle body 1, make being of convenient length of the anterior syringe needle 3 of adjusting nut 9, rotatably compress nut 8 and lean against on adjusting nut 9 its positioning and locking, avoid shift in position.
A kind of marrow puncture needle of the present utility model, can implement bone puncture fast, easy and simple to handle, time saving and energy saving, alleviates patient's misery, and easily puncture during harder patient at the puncture sclerotin, improves puncture success rate.In use, at first choose needle gage, adjust the position of adjusting nut, and fix with clamp nut, then grasping handle marrow puncture needle is revolved and pricks into bone marrow, vertical facial is slightly firmly rotated needle body and is slowly entered medullary cavity, when the sensation resistance reduces, prompting enters medullary cavity, extracts nook closing member, connects dry asepsis injector, bone marrow extraction, smear, finally return the contact pin core immediately, with the opposite direction slow circumvolve, marrow puncture needle extracted.A kind of marrow puncture needle of the present utility model, adjusting nut can flexible syringe needle length, meets the requirement of different patients to needle length, sharpness when the sharp keen screw wing that projection is set on the cylindrical of syringe needle has increased puncture, the handle design of hommization, the operation of being more convenient for while guaranteeing puncture.
