Abstract
The utility model relates to a thin slice formula pedicle of vertebral arch osteotome belongs to the medical instrument field, and it need be in the pedicle of vertebral arch cuts the operation of bone to be applicable to. Thin slice formula pedicle of vertebral arch osteotome includes blade (1) and handle of a knife (2) two parts, and blade (1) position is thin, and handle of a knife (2) position designs into thin rectangle form and long, and the handle of a knife has the arcuation sunken on the surface, and blade and handle of a knife formula structure as an organic whole has improved thin slice formula pedicle of vertebral arch osteotome's intensity. Thin slice formula pedicle of vertebral arch osteotome can not shelter from at the operation in -process and cuts the bone operation under the circumstances in the field of vision, and the normal position that can carry on after the osteotome inserts is simultaneously waved and rotation operations, and the handle of a knife can not collide each other, offers convenience for the operation, and blade (1) is connected the position with handle of a knife (2) and is set up chamfer (5), and messenger's thin slice formula osteotome is difficult for breaking.
Description
Technical field
This utility model relates to a kind of sheet type pedicle of vertebral arch osteotome, belongs to medical instruments field, is applicable to need in the operation of pedicle osteotomy.
Background technology
In long-term clinical practice, pedicle of vertebral arch osteotome is done to carry out pedicle and is blocked vertebral body skeleton when bone surgery.
The multinomial lopsided orthomorphia of spinal surgery all needs to carry out osteotomy to pedicle of vertebral arch.How these operations at clinical expansion over several years, reach the key point that convenient and safe pedicle of vertebral arch osteotomy is operation.
Pedicle osteotomy traditional at present has following shortcoming:
1. osteotome is thicker, osteotomy while simultaneously can not completing the upper and lower edge of pedicle, increases the time of operation technique; 2. owing to can not complete upper and lower edge osteotomy simultaneously, therefore pedicle of vertebral arch osteotomy angle controls not good; 3. upper and lower edge uses sheet type pedicle of vertebral arch osteotome to also have an advantage to be, when after upper and lower two sheet type pedicle of vertebral arch osteotomes simultaneously osteotomy, the handle of a knife that operator can hold two sheet type pedicle of vertebral arch osteotomes carries out slight waving and rotate, be conducive to from disconnected osteotomy end, improve osteotomy efficiency, and the osteotomy mode of traditional osteotome cannot complete this operation.
Visible, develop a kind of simple and reliable for structure, operation technique is convenient, the osteotomy device little to human body wound, waits carrying out of performing the operation to have important realistic meaning to osteotomy is orthopedic.
Summary of the invention
The purpose of this utility model is: for prior art Problems existing, provides a kind of sheet type pedicle of vertebral arch osteotome, can carry out the operation of accurate pedicle osteotomy, bring efficiency and facility to operation in operation process.
To achieve these goals, this utility model provides a kind of sheet type pedicle of vertebral arch osteotome, described sheet type pedicle of vertebral arch osteotome comprises blade and handle of a knife two parts, blade position is thin and grow, blade thickness is thinning gradually, draw in gradually in cutting edge, cutting edge is sharp, be convenient to insert the operative site needing osteotomy, handle of a knife position is designed to thin rectangular-shaped, compared with traditional cylindrical handle, surgical field of view can not be blocked during operation, original position after simultaneously can carrying out osteotome insertion is waved and rotation process, and handle of a knife can not collide mutually, the operation of performing the operation of being more convenient for.
Preferably, the arcuate recess on described handle of a knife surface, holds when being convenient to operation, has anti-skidding effect, under the prerequisite not reducing serviceability, also mitigate the weight of sheet type osteotome.
Preferably, described blade and handle of a knife are integral type structure, improve the intensity of sheet type osteotome.
Accompanying drawing explanation
Fig. 1 is operation schematic diagram of the present utility model
Fig. 2 is structure composition of the present utility model
In figure:
1 blade, 2 handle of a knifes, 3 cutting edges, 4 grooves, 5 chamferings.
Detailed description of the invention
For making the purpose of this utility model, technical scheme clearly, below in conjunction with accompanying drawing, this utility model is described in further detail.
Shown in Fig. 2, according to the sheet type pedicle of vertebral arch osteotome of a kind of preferred implementation of this utility model, sheet type pedicle of vertebral arch osteotome comprises blade 1 and handle of a knife 2 two parts, blade 1 position is thin and grow, blade thickness is thinning gradually, draw in cutting edge 3 gradually, cutting edge 3 is sharp, be convenient to insert the operative site needing osteotomy, handle of a knife 2 position is designed to thin rectangular-shaped, compared with traditional cylindrical handle, surgical field of view can not be blocked during operation, original position after simultaneously can carrying out osteotome insertion is waved and rotation process, handle of a knife can not collide mutually, be more convenient for perform the operation operation.
Arcuation groove 4 on described handle of a knife 2 surface, holds when being convenient to operation, has anti-skidding effect, under the prerequisite not reducing serviceability, also mitigate the weight of sheet type pedicle of vertebral arch osteotome.
Described blade 1 and handle of a knife 2 are integral type structure, improve the intensity of sheet type pedicle of vertebral arch osteotome, and blade 1 and handle of a knife 2 connecting portion arrange chamfering 5, make sheet type pedicle of vertebral arch osteotome not frangibility.
Claims (3)
1. sheet type pedicle of vertebral arch osteotome, it is characterized in that, comprise blade (1) and handle of a knife (2) two parts, position is thin and grow for blade (1), blade (1) thickness is thinning gradually, draw in cutting edge (3) gradually, cutting edge (3) is sharp, be convenient to insert the operative site needing osteotomy, handle of a knife (2) position is designed to thin rectangular-shaped, compared with traditional cylindrical handle, surgical field of view can not be blocked during operation, original position after simultaneously can carrying out osteotome insertion is waved and rotation process, and handle of a knife can not collide mutually, the operation of performing the operation of being more convenient for.
2. sheet type pedicle of vertebral arch osteotome according to claim 1, it is characterized in that: the arcuation groove (4) on described handle of a knife (2) surface, hold when being convenient to operation, there is anti-skidding effect, under the prerequisite not reducing serviceability, also mitigate the weight of sheet type pedicle of vertebral arch osteotome.
