Abstract
The utility model relates to a medical spiral marrow biopsy needle, in particular to a medical spiral marrow biopsy needle apparatus. A moveable jacket and a conical sleeve are arranged on a handle pinhead, a spiral wire is arranged at the tip part of a puncture needle, a needle core is arranged at the center of the handle, moveable jackets with various length are sleeved on the needle core according to the shape of a patient, the conical sleeve is sleeved on the needle core, the puncture needle is drawn out after being inserted in muscle, then the marrow biopsy needle is inserted in the conical sleeve, marrow is collected and examined by the spiral pinhead and is brought out in the spiral wire, the conical sleeve is fixedly connected with the handle, and the spiral pinhead device is arranged in the conical sleeve, therefore a marrow collecting device is formed. The utility model has simple structure, safe and convenient operation, high puncture success rate and low cost, reduces the pain of a patient, can successfully collects marrow once, and can be widely for clinic patients.
Description
Technical field:
This utility model relates to a kind of medical screw type myeloid biopsy needle, particularly medical screw type myeloid biopsy needle apparatus.
Background technology:
At present, myeloid biopsy needle in the prior art, its defective is that syringe needle is a rhombus, 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, complex operation, the cost height, success rate is low, is unfavorable for using clinically.
Summary of the invention:
The purpose of this utility model, providing a kind of medical screw type myeloid biopsy needle, is to overcome above-mentioned defective and design a kind of screw type myeloid biopsy needle, and it is to adopt needle tip that taenidium is set, sclerotin is at the spiral place, extract the screw type syringe needle out, take out sclerotin, the once success rate height, handling safety is reliable, cost is low, reduces the patient suffering, is widely used in the prison bed and goes up the bone marrow needle biopsy patient.
The medical screw type myeloid biopsy needle of this utility model 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 the medical screw type myeloid biopsy needle of this utility model 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.
Description of drawings:
The medical screw type myeloid biopsy needle of this utility model will describe in further detail in conjunction with the accompanying drawings.
Accompanying drawing is the structural representation of the medical screw type myeloid biopsy needle of this utility model.
1---handle 2---movable sleeve 3---circular cone sleeve pipe 4---spiral syringe needle
The specific embodiment:
With reference to accompanying drawing, the medical screw type myeloid biopsy needle of this utility model, 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 the medical screw type myeloid biopsy needle of this utility model, 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 taenidium.
