In order to solve the problems of the technologies described above, this utility model comprises drilling rod and is fixed on the handle on drilling rod, and drilling rod is provided with the thread eye at the axial through drilling rod of drilling rod, and be inserted with seal wire in thread eye, seal wire is longer than drilling rod.
For the ease of processing and fabricating, described drilling rod comprises drill bit and drill bit fixed bar, and the upper end of drill bit and the lower end of drill bit fixed bar fix, and handle is fixed on drill bit fixed bar, the through drill bit of described thread eye and drill bit fixed bar.
Exit from boring for ease of drilling rod, it is non-circular groove that the lower end surface of described drill bit fixed bar is provided with cross section, the upper end shape of drill bit is corresponding to the shape of the groove on drill bit fixed bar, the upper end of drill bit to be inserted in described groove and to fit with cell wall, drill bit fixed bar is provided with lock-screw, lock-screw is threaded with the cell wall on drill bit fixed bar, seal wire hole wall on drill bit is provided with locating hole, locating hole on drill bit is connected with thread eye, when lock-screw rotates in locating hole, bit upper end face is pushed up on the bottom surface of the groove on drill bit fixed bar.
For the ease of determining the locking state of lock-screw, described lock-screw is provided with lock-screw and enters the labelling that the labelling of locating hole and lock-screw enter thread eye.
In order to easy to operate, described handle has two, and two handles are separately fixed at the both sides of drilling rod.
In order to be suitable for different working places, described handle is the handle of adjustable in length.
Conveniently observe drilling depth, described drilling rod is provided with the scale of mark drilling depth.
The beneficial effects of the utility model are: this utility model adopts hand drill, in drilling rod, seal wire is set, because the speed of hand drill is slower, drilling depth is easy to control, hole under the cooperation that drill bit is located at CT, bore position accuracy is high, and after boring, seal wire is retained in hole, enter in bone tumor for biopsy needle guide, thus particle can accurately be put in bone tumor.

Detailed description of the invention
Specific embodiment one
This specific embodiment as depicted in figs. 1 and 2, it comprises drilling rod and is fixed on two handles 3 on drilling rod, drilling rod comprises drill bit 5 and drill bit fixed bar 2, the upper end of drill bit 5 and the lower end of drill bit fixed bar 2 fix, two handles 3 are separately fixed at the both sides of drill bit fixed bar, and handle 3 adopts length-adjustable handle.Drilling rod is provided with the thread eye at the axial through drilling rod of drilling rod, the through drill bit 5 of thread eye and drill bit fixed bar 2.Be inserted with seal wire 1 in thread eye, seal wire 1 is longer than drilling rod.Drill bit 5 is provided with the scale 6 of mark drilling depth.
It is non-circular groove that the lower end surface of drill bit fixed bar 2 is provided with cross section, the upper end shape of drill bit 5 is corresponding to the shape of the groove on drill bit fixed bar 2, the upper end of drill bit 5 to be inserted in described groove and to fit with cell wall, drill bit fixed bar 2 is provided with lock-screw 4, lock-screw 4 is threaded with the cell wall on drill bit fixed bar 2, seal wire hole wall on drill bit 5 is provided with locating hole, locating hole on drill bit 5 is connected with thread eye, when lock-screw 4 rotates in locating hole, drill bit 5 upper surface is pushed up on the bottom surface of the groove on drill bit fixed bar 2, thus make drill bit 5 be fastened on drill bit fixed bar 2, both can not rotate and also can not occur to jump up and down.Lock-screw 4 is provided with lock-screw 4 and enters the labelling that the labelling of locating hole and lock-screw enter thread eye, and labelling can be aperture, indentation or graticule.
Operation principle: under CT location, drill bit 5 is pierced bone by manual operations, after CT guides lower adjustment direction and penetration depth, be drilled into that osteocarcinoma is swollen to be drafted in tumor tissue, exit drill bit 5, seal wire 1 is stayed in tumor tissues, inserts particle puncture needle along seal wire 1, extract seal wire 1 after putting in place, implant particle along puncture needle.Before brill bone, lock-screw 4 can be screwed into thread eye, seal wire 1 is compressed, prevent seal wire from jumping up and down in thread eye, bore bone complete, before exiting drill bit, lock-screw 4 is exited thread eye, and drill bit fixed bar 2 and drill bit 5 are extracted out, seal wire 1 is retained in boring.Brill bone is complete, and before exiting drill bit, also lock-screw 4 can be exited locating hole, drill bit fixed bar 2 and drill bit 5 are extracted out respectively, seal wire 1 is retained in boring.
