1-4 is described in further details specific embodiment of the present utility model with reference to the accompanying drawing.
Embodiment one, is provided by Fig. 1, Fig. 2, Fig. 3 and Fig. 4, and the utility model includes sting device 1,1 side of sting device
It is connected with internal core device 2, internal core device 2 is mounted on inside sting device 1, then sting device 1 is lunged into lesions position, is taken out
Internal core device 2,1 other side of sting device are connected with negative pressure pump 3, after taking out internal core device 2,3 one end of negative pressure pump and puncture dress
1 connection is set, forms negative pressure inside sting device 1 under the action of negative pressure pump 3, takes out sting device 1, the use of negative pressure pump 3 can
To prevent biopsy from falling off during taking-up, then internal core device 2 is put into inside sting device 1, takes out pathology
Tissue；
Sting device 1 includes hollow cone 11, the first tip 12, sawtooth 13, first handle 14 and the first screw thread 15, hollow cone
11 one end are fixed with the first tip 12, and 12 side of the first tip is fixed with sawtooth 13, and 11 angle tip 12 of hollow cone uses sawtooth
13 to be easy for entering bone tissue in puncture process, while the area ratio flat mouth of angle will be cut greatly in puncture process
It is obviously increased to the success rate effectively organized, 11 both sides external of hollow cone is equipped with first handle 14, and finger holds first handle
14, facilitate and punctured, 14 other end of first handle is fixed with the first screw thread 15, and the first screw thread 15 is for connecting internal core device
2；
Internal core device 2 includes centrum 21, the second tip 22, second handle 23 and the second screw thread 24, and 21 one end of centrum is fixed
There is the second tip 22,21 other end of centrum is equipped with second handle 23, and centrum 21, the second tip 22 and the insertion of second handle 23 are worn
, can be full being filled inside sting device 1 when 1 inside of thorn device, the second screw thread 24, the second spiral shell are fixed with inside second handle 23
Line 24 is connect with the first screw thread 15, and internal core device 2 is fixed on inside sting device 1；
