Abstract
The utility model relates to a vertebral lamina drill for bone surgery, applying to chest and vertebral canal stenosis, prolapse of lumbar intervertebral disc, spinal cord tumor resection and the others bone surgeries which need the incision of vertebral plate. The utility model is structured that the drill is composed of a twisting hand drill and a drill sleeve, wherein the upper end of a drill rod of the twisting hand drill is provided with a hand handle under which is provided with a screw thread, and an auger bit is arranged at the lower end of the drill rod. Arranged a knurling on the wall of the upper end and a screw thread on the inner wall, the lower end of the drill sleeve is provided with a dowel hole, and the twisting hand drill is installed in the drill sleeve via nesting. The utility model has the advantages of safety in utilization, harmlessness to the nerve, apparent hand touch after break-through of the vertebral lamina, and tidy bone window wall, resulting in less bleeding, thereby speeding up the surgery and guaranteeing the surgery quality by employing the utility model.
Description
This utility model relates to the Vertebral plate drill that a kind of bone surgery is used, and is mainly used in breast, lumbar spinal stenosis, prolapse of lumbar intervertebral disc, and the tumor of spinal cord excision, and other need cut the bone surgery of vertebral plate.
In the canalis spinalis operation of orthopaedics routine, need the cut-out vertebral plate to appear.At present, Chang Yong operating theater instruments has two kinds of osteotome and the rongeurs of rifle shape.Use the osteotome person to require to be skilled in technique, and very careful, otherwise the easy damaged nerve root causes patient's permanent disbility.When removing vertebral plate, as when running into the serious patient of osteosclerosis, vertebral plate plumpness, little joint hyperplasia, almost can't enter the vertebral plate gap with the rongeur of rifle shape, sting motionless vertebral plate, very require great effort, and speed is slow, hemorrhage many, also can cause dura mater to tear sometimes, the damage cauda equina nerve.
When the purpose of this utility model is exactly a kind of orthopaedics canalis spinalis operation of developing at the problems referred to above, cut the Vertebral plate drill that vertebral plate is used, it is bored by the hands strand and drill bushing two parts are formed.There is handle the top that hands strand is bored drilling rod, under the handle screw thread is arranged, drilling rod spiral bit arranged bottom; On the outer wall of drill bushing upper end annular knurl is arranged, screw thread is also arranged on the inwall, there is dowel hole the drill bushing lower end, and hands strand drill bushing is contained in the drill bushing.
The utlity model has following advantage:
1, it is fast to drill into canalis spinalis speed with this, because of drill bit pitch is 1mm, whenever firmly circles and promptly enters 1mm, only needs 5-7 to change and can break through vertebral plate.
2, bore safety with this, feel is obvious behind the breakthrough vertebral plate, and has the overcoat protection can not fall through, therefore can injured nerve.
3, bore the efficient height with this, when a plurality of vertebral plates need cut, can side by side bore several holes more, and then enlarge towards periphery, can obviously improve operative speed like this with osteotome or rifle shape pincers.
4, get out insufficiency of blood with this.Neat because of bone window wall, can stop blooding with bone is cured.
When 5, making simple lumbar intervertebral disc operation with this brill, as long as accurate positioning, vertebral lamina fenestration only need can be finished in about one minute, and guaranteed the operation quality.
Description of drawings:
Fig. 1 is a population structure sketch map of the present utility model
Fig. 2 is that hands strand of the present utility model is bored sketch map
Fig. 3 is a drill bushing sketch map of the present utility model
In the accompanying drawing: 1 hands strand is bored annular knurl 7 box threads 8 spiral bits 9 dowel holes 10 Vertebral plate drills on 2 handles, 3 drilling rods, 4 male threads, 5 drill bushings, 6 outer walls
The utility model is described in further detail below in conjunction with accompanying drawing:
Provided concrete structure of the present utility model among Fig. 1,2,3, Vertebral plate drill 10 is made of hands strand brill 1 and drill bushing 5 two parts.
Hands strand bores 1: there is handle 2 the top of drilling rod 3, and there is male thread 4 in handle bottom, drilling rod 3 be spiral bit 8 bottom, bit diameter is 12mm;
Drill bushing 5: on the outer wall of drill bushing upper end convex concave annular knurl 6 is arranged, box thread 7 is arranged on the inwall, so that match and revolve with screw thread 4 on the drilling rod, there is dowel hole 9 the drill bushing lower end, and the dowel hole internal diameter is than the big 0.3-0.5mm of diameter of spiral bit 8; The hands strand is bored 1 and is sleeved in the drill bushing 5.
During use, Vertebral plate drill is placed on corresponding vertebral plate place, one hand steered maintains static it at drill bushing annular knurl place, and another holds handle, and clockwise direction rotates, and brill that just can safety be opened vertebral plate, and feel is obvious when boring.
