Rate is clinician always in the thing of concern.In current Centesis instrument, multi-point sampling places one's entire reliance upon the puncture of patient
Technology obtains more puncturing tissues by changing the channel depth punctured and direction or single bilateral, but due to pedicle of vertebral arch
The change angle of limited internal diameter, puncture needle direction is very limited, and increases the number of fluoroscopy during operation, increases patient and patient
The reconditioning of equal related personnel, thus need by Centesis instrument --- and the improvement of Spinal Metastatic Tumors puncture channel increases
Add biopsy efficient and reduces the reconditioning of X piece.
Summary of the invention
The purpose of the present invention is to provide a kind of Spinal Metastatic Tumors puncture channels, and taking for aspiration biopsy can be greatly improved
Material range, to improve biopsy recall rate.
One aspect of the present invention provides a kind of Spinal Metastatic Tumors puncture channel, including casing and inner core；Described sleeve pipe
For the hollow structure with sleeve through hole, described sleeve pipe front end is elbow structure；The inner core is with the hollow of inner core through-hole
Structure, front end are inner core cutter head, and the inner core front is additionally provided with inner core spring；The inner core can be slided in described sleeve pipe through-hole
It is dynamic.
Above-described Spinal Metastatic Tumors puncture channel, wherein the curved angle of the elbow structure of described sleeve pipe front end
It is in 0-90 degree with described sleeve pipe axis；Preferably, 0 °, 30 °, 60 °, 90 ° of four kinds of specifications can be designed to.
Above-described Spinal Metastatic Tumors puncture channel, which is characterized in that the intensity of the inner core spring can support institute
Interior core sampling is stated, and can be bent under the guidance of described sleeve pipe elbow structure.
With above-mentioned Spinal Metastatic Tumors puncture channel, wherein the inner core cutter head is the sharp tooth that gathers.
The present invention also provides a kind of Spinal Metastatic Tumors pricking devices, wherein the equipment has used any of the above institute
The puncture channel stated.
Beneficial effect
The invention discloses a kind of Spinal Metastatic Tumors puncture channels, including casing and inner core；Casing is logical with casing
The hollow structure in hole, casing front end are elbow structure；Inner core is the hollow structure with inner core through-hole, and front end is inner core knife
Head, inner core front are additionally provided with inner core spring；Inner core can slide in sleeve through hole.Casing of the present invention can be punctured into pedicle of vertebral arch
Lesions position is reached, inner core is being in casing axis due to that can be bent under the guidance of the elbow structure of casing with inner core spring
Puncturing tissue is obtained on the direction of certain angle, after casing changes paracentesis depth, and can continue to obtain in different paracentesis depths
Puncturing tissue expands the range that can obtain puncturing tissue, while increasing the probability for effectively obtaining lesion tissue, and then improve
Biopsy rate.

Specific embodiment
The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention..Unless otherwise specified, embodiment
Used in the conventional means that are well known to those skilled in the art of technological means.
" preceding " described in the present embodiment, " front end " " front " refer both to using when close to the one of lesion or surgical procedure position
End or a part, " rear " " rear end " " rear portion " refer both to using when one end far from lesion or surgical procedure position or one
Point.
Embodiment 1
Referring to shown in Fig. 1 to Figure 12, present embodiments providing a kind of Spinal Metastatic Tumors puncture channel, including 1 He of casing
Inner core 2；Casing 1 is the hollow structure with sleeve through hole 11, and 1 front end of casing is elbow structure, the curved angle of elbow structure
It is in 0-90 degree with 1 axis of casing, it is preferable that can be designed as 0 °, 30 °, 60 ° of three kinds of specifications, angle is excessive to will lead to casing 1 not
