Description
This utility model screw type myeloid biopsy needle belongs to medical bone marrow aspiration screw type biopsy needle apparatus.
Myeloid biopsy needle in the prior art, phase defective are that syringe needle is a prismatic, and sclerotin easily comes off, in patient's sclerotin place repeatable operation, until successfully extract out till the sclerotin, cause suffering to the patient, patient's sclerotin place is repeatedly damaged, the tired lock of operation, the cost height, success rate is low, is unfavorable for using on the prison bed.
The purpose of this utility model screw type myeloid biopsy needle, be to overcome above-mentioned defective and design a kind of screw type myeloid biopsy needle, it is to adopt needle tip that taenidium is set, and sclerotin is extracted the screw type syringe needle out at the spiral place, take out sclerotin, the once success rate height, handling safety is reliable, and cost is low, reduce the patient suffering, be widely used in the prison bed and go up the bone marrow needle biopsy patient.
This utility model screw type myeloid biopsy needle takes following technical scheme to realize, it is by movable sleeve and circular cone sleeve pipe are set on the handle syringe needle, the puncture needle tip is provided with taenidium, the handle center place is provided with nook closing member, be nested with movable sleeve different in size according to the patient is fat or thin, movable sleeve is nested with on nook closing member, the conical sleeve pipe box is put on nook closing member, piercing needle is extracted out after inserting muscle, myeloid biopsy needle inserts in the circular cone sleeve pipe again, adopts the inspection sclerotin by the screw type syringe needle, and sclerotin is taken out of in taenidium, circular cone sleeve pipe and handle are connected and fixed, and the screw type needle apparatus constitutes in the circular cone sleeve pipe gathers the sclerotin apparatus.
The effect of this utility model screw type myeloid biopsy needle is simple in structure, easy-to-operate, and the successful efficient height that punctures, cost is low, reduces the patient suffering, gathers the disposable success of sclerotin, is widely used in the apparatus of clinical patients bone marrow biopsy.
This utility model screw type myeloid biopsy needle will describe in further detail in conjunction with the accompanying drawings.
Accompanying drawing is the structural representation of this utility model screw type myeloid biopsy needle.
1-handle 2-movable sleeve 3-circular cone sleeve pipe 4-spiral syringe needle
With reference to accompanying drawing, this utility model screw type myeloid biopsy needle, it is by being nested with movable sleeve 2 and circular cone sleeve pipe 3 on handle 1 syringe needle, on handle 1 syringe needle spiral syringe needle 4 is set, needle tip is provided with taenidium, handle 1 center is provided with nook closing member, and movable sleeve 2 is provided with different length specification movable sleeve 2, and movable sleeve 2 is nested with on spiral syringe needle 4 with circular cone sleeve pipe 3.During use, behind puncture needle and circular cone sleeve pipe 3 insertion muscle, extract puncture needle out, spiral syringe needle 4 is gone into sclerotin from circular cone sleeve pipe 3 interpolations, and rotating screw syringe needle 4 is extracted spiral syringe needle 4 out, adopts sclerotin in the inspection taenidium.
The embodiment of this utility model screw type myeloid biopsy needle, it is by being nested with movable sleeve 2 and circular cone sleeve pipe 3 on handle 1 syringe needle, on handle 1 syringe needle spiral syringe needle 4 is set, needle tip is provided with taenidium, handle 1 center is provided with nook closing member, movable sleeve 2 is the different length specification, and movable sleeve 2 is nested with on spiral syringe needle 4 with circular cone sleeve pipe 3.During use, behind puncture needle and circular cone sleeve pipe 3 insertion muscle, extract puncture needle out, spiral syringe needle 4 is gone into sclerotin from circular cone sleeve pipe 3 interpolations, and rotating screw syringe needle 4 is extracted spiral syringe needle 4 out, adopts sclerotin in the inspection spiral.
