Abstract
The invention relates to a vertebral arch pedicle bone chisel with an arc-shaped cutting edge. The vertebral arch pedicle bone chisel consists of a handle, an inclined rod and a cutter head, wherein the handle is fixed to the rear end of the inclined rod, and the cutter head is fixed to the front end of the inclined rod. The vertebral arch pedicle bone chisel is characterized in that the axis of the handle is parallel to that of the cutter head, and the front end part of the cutter head is provided with the arc-shaped cutting edge. Compared with the currently-used traditional bone chisels, the vertebral arch pedicle bone chisel with the arc-shaped cutting edge has the advantages that the structure is simple, the use is convenient, tissue, such as nerve roots and spinal cords, around vertebral arch pedicle cannot be injured during bone chiseling surgery, the surgery is safe and reliable, the time for the surgery is shortened, and the efficiency and success rate of the surgery are increased.
Description
Technical field
The present invention relates to a kind of improvement of osteotome, belong to medical instrument technical field, specifically a kind of pedicle of vertebral arch osteotome with curved blade and application thereof.
Background technology
Osteotome is widely used in orthopaedics, particularly in spinal surgery and tumor of spine surgical operation, is mainly used in revising skeleton, getting bone and osteotomy.The osteotome of current use, as Fig. 3: be made up of handle 1, straight-bar 5, cutter head 3 and rectilinear edge 6, the rear end fixed handle 1 of straight-bar 5, cutter head 3 is fixed in the front end of straight-bar 5, the dead in line of handle 1, straight-bar 5 and cutter head 3, and the leading section of cutter head 3 is provided with rectilinear edge 6.Its weak point is: in spinal surgical procedure, common osteotome is usually used in osteotomy and fenestration procedure, and when for blocking pedicle of vertebral arch, the front end due to cutter head is rectilinear edge, in operation, osteotome easily horizontally slips, thus the important feature such as nerve root, spinal cord of damage pedicle of vertebral arch periphery.
Summary of the invention
The object of the present invention is to provide a kind of structure simple, easy to use, in the operation process of cutter bone, the pedicle of vertebral arch osteotome of the band curved blade of the nerve root of pedicle of vertebral arch periphery can not be damaged.
For achieving the above object, the technical scheme that the present invention takes is: a kind of pedicle of vertebral arch osteotome with curved blade, be made up of handle, brace and cutter head, the two ends of described brace are fixed with handle and cutter head respectively, the axis of described handle and the axis being parallel of described cutter head, the leading section of described cutter head is provided with curved blade.
The axis of described brace is pitched with the axis of handle and the axes intersect of cutter head respectively.
The shape of described curved blade and the mating shapes of pedicle of vertebral arch.
The invention has the advantages that:
A kind of pedicle of vertebral arch osteotome with curved blade of the present invention is compared with the traditional osteotome used at present, its structure is simple, easy to use, in the operation process of cutter bone, the tissues such as the nerve root of pedicle of vertebral arch periphery, spinal cord can not be damaged, safe and reliable, shorten operating time, improve procedure efficiency and success rate.
Accompanying drawing explanation
Accompanying drawing 1 is the front view of a kind of pedicle of vertebral arch osteotome structure with curved blade of the present invention.
Accompanying drawing 2 is that the cutter head structure of a kind of pedicle of vertebral arch osteotome structure with curved blade of the present invention overlooks enlarged diagram.
Accompanying drawing 3 is structural representations of traditional osteotome.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention provided by the invention is elaborated.
The Reference numeral related in accompanying drawing and ingredient as follows:
1. hands handle; 2. brace; 3. cutter head; 4. curved blade;
5. straight-bar; 6. rectilinear edge.
As shown in Figures 1 and 2, a kind of pedicle of vertebral arch osteotome with curved blade, be made up of handle 1, brace 2 and cutter head 3, the two ends of described brace 2 are fixed with handle 1 and cutter head 3 respectively, the axis of described handle 1 and the axis being parallel of described cutter head 3, the leading section of described cutter head 3 is provided with curved blade 4, the described shape of curved blade 4 and the mating shapes of pedicle of vertebral arch.The axis of described brace 2 is pitched with the axis of handle 1 and the axes intersect of cutter head 3 respectively, like this in the process of cutter bone, can not damage the tissue around pedicle of vertebral arch, safe and reliable, improves the success rate of operation.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the inventive method; can also make some improvement and supplement, these improve and supplement and also should be considered as protection scope of the present invention.
