Pathological tissue is obtained, biopsy rate is higher.
To achieve the above object, the technical scheme adopted by the utility model is it is a kind of for old vertebral compression bone
The centrum of folding takes biopsy device, including fetching rod, fixed clamp bar and movable supporting rod, and fetching rod is hollow structure inside, is taken
One end of object bar is fixedly connected with fixed clamp bar, and the other end of fetching rod is equipped with fixed clamp mouth and activity clamping mouth, the end
Inlet is offered, is equipped with connecting shaft in inlet, the both ends of connecting shaft are installed in respectively on fetching rod inner wall, activity clamping mouth
One end be hinged in connecting shaft, and the end is fixedly connected by a flexible draw bar with movable supporting rod, and fixed clamp mouth is solid
It is located in fetching rod；
Between the fetching rod and fixed clamp bar at an angle, fixed clamp bar is hollow structure inside, and fixed
Cavity in supporting rod is connected with the cavity in fetching rod, and the side on the head of fixed clamp bar is clamped by pin shaft and activity
Bar connection, when movable supporting rod is pulled in one end towards fixed clamp bar, movable supporting rod passes through flexible draw bar pulling activity
Clamping mouth is adjacent to fixed clamp mouth, to clamp the pathological tissue of solid-state or semisolid；
The tail portion of the fixed clamp bar offers the hollow cavity of liquid outlet, liquid outlet and fixed clamp bar and fetching rod
It is connected to, when connecting pumping device at liquid outlet, liquid pathological tissue can be extracted.
Further, the fetching rod is made of transparent material, and fetching rod is distinguished on one end of movable supporting rod
Offer the placement depth for observing fetching rod the first graduation mark and for observe extract liquid pathological tissue second
Graduation mark.
Further, the rear end of the fixed clamp bar and movable supporting rod is respectively equipped with hand-held part.
Further, the pumping device is syringe.
Compared with prior art, the utility model has the following beneficial effects:
The utility model apply to it is a kind of for old compression fracture of vertabral body patient in percutaneous vertbroplasty or art
Before take biopsy, not only have the advantages that conventional percutaneous casing biopsy needle, but also the device is woven in for the group of different sclerotin properties
Punctured under local anaesthesia it is safe and simple, repeatedly, repeatedly obtain pathological tissue, biopsy rate is higher, and accuracy rate reaches 90%.In addition, in CT
Guided percutaneous biopsy is easy to operate, safety, few intercurrent disease, wound infection chance are small, can obtain more pathological tissue,
There are higher puncture positive rate and accuracy rate, is worth clinically promoting and applying.
