Description

A kind of bone negative pressure biopsy device
Technical field
The utility model belongs to medical instruments field, and in particular to be a kind of bone negative pressure biopsy device.
Background technology
Pathological biopsy has important clinical meaning in the diagnosis of Bone and soft tissue tumors, mainly has open biopsy with wearing Biopsy two ways is pierced, because open biopsy required time is long, costly, complication is more, and aspiration biopsy has convenient, province When, expense is low and the advantages such as complication is less, increasingly used by vast bone tumour section doctor.But clinically use at present Biopsy needle come with some shortcomings part, one of major defect is that often occur can not taking biopsy or take out a small amount of living The situation of inspection, the diagnosis of bone tumour is caused deviation occur, so as to influence the diagnosis and treatment of patient.
The content of the invention
The purpose of this utility model is directed to drawbacks described above, there is provided a kind of bone negative pressure biopsy device, work is punctured to improve clinical bone The accuracy of inspection.
Bone negative pressure biopsy device provided by the utility model, including syringe and needle tubing, the syringe and needle tubing screw thread are close Envelope connection, the needle tubing are provided with jagged needle point, and the inside of needle tubing is provided with nook closing member, and the end of the nook closing member is located at syringe It is interior.
The needle tubing is provided with lever.
The top of the nook closing member is provided with conical head, for being opened a way during percutaneous puncture.
Before aspiration biopsy, syringe is first removed, by the percutaneous inserting needle of needle tubing with nook closing member, needle point is reached lesion region side Edge, nook closing member is then extracted, needle tubing is knocked in into diseased region and rotates jagged needle point, needle tubing is passed through lesion region, then will Needle tubing is connected with syringe, then makes to produce negative pressure in needle tubing, so as to suction out more complete biopsy group by syringe pumpback rapidly Knit.
The utility model has simple in construction, easy to operate, the features such as production cost is low, with existing biopsy needle phase Than can guarantee that and take out more complete biopsy, improve the accuracy of Diagnosis of Bone Tumor.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.In figure:1- needle points, 2- needle tubings, 3- nook closing members, 4- levers, 5- injections Device, 6- conical heads.
Embodiment
The utility model is described in detail below by way of specific embodiment.
A kind of bone negative pressure biopsy device, including syringe 5 and needle tubing 2, the syringe 5 are connected with the thread seal of needle tubing 2, institute The top for stating needle tubing 2 is provided with jagged needle point 1, and the inside of needle tubing 2 is provided with nook closing member 3, and the end of the nook closing member 3 is located at syringe In 5, the top of nook closing member 3 is provided with conical head 6, and for being opened a way during percutaneous puncture, the needle tubing 2 is provided with lever 4.
During aspiration biopsy, syringe 5 is first removed, by the 2 percutaneous inserting needle of needle tubing with nook closing member 3, when needle point 1 reaches diseased region During the edge of domain, nook closing member 3, rotation and the percussion tail end of needle tubing 2 are extracted, and needle point 1 is penetrated cortex bone, continuing rotation needle tubing 2 makes it It is connected through pathological tissues, then by needle tubing 2 with syringe 5, rapid pumpback syringe 5 makes to produce negative pressure in needle tubing 2, while from body It is interior to extract needle tubing 2 together with syringe 5, so as to take out more complete biopsy.By clinical verification, the utility model energy is used More complete biopsy is taken out, success rate is up to 99%.
