Abstract
Get a device spanner for holding in orthopedic spinal nail-stick system, comprising: hold and get bar, tapered end and spring leaf; Wherein hold get bar form hold the main body of getting device spanner, tapered end is fixedly installed on the one end of holding and getting bar, and tapered end cross section is hexagon shape and periphery is provided with mounting groove, and spring leaf is fixedly installed in above-mentioned mounting groove.In use, be stuck in spring leaf on tapered end in mounting groove and insert six sides in jackscrew in company with tapered end entirety, utilize the rebound effect of spring leaf that spring leaf and six side's inwalls are clamped, thus holding in operation can be completed fast and accurately get jackscrew and pretension process.Structure of the present utility model is simple and hold and get firmly, reduces operation risk, reduces the misery of patient.
Description
Technical field
This utility model relates to the technical field of operating theater instruments, is specifically a kind ofly to get device spanner for holding in orthopedic spinal nail-stick system.
Background technology
Along with the raising of people's living standard and the transformation of people life style, the damage of some skeletons is unavoidably there is in daily, cervical spine injury becomes disease common in Orthopedic Clinical, especially fracture-dislocation of cervical spine, serious fracture dislocation often dislocate heavy or merge multiple fracture cause cervical vertebra three rod structure to destroy, loss of stability, spinal cord and function of nervous system are badly damaged, a lot of patient needs tracheotomy to rescue life, loses the chance that anterior approach is fixing, further increases the difficulty for the treatment of.Cervical Pedicle Screw rod internal fixtion can reset and provide reliable three posts to fix effectively, and can reduce pressure while fixing, thus reconstruction spinal column stability at once, the spinal cord injury that alleviates, promotion spinal cord and neurological functional recovery.In enforcement operation process, nail rod is held to get be a requisite step, the jackscrew of spine pedicle screws rod is interior hexagonal structure, holds fixed structure in getting and insecure, easily occur in clinical holding getting and lost efficacy or occurred connecting the problem come off in upper nail process, easily cause operative failure.
Utility model content
The technical problems to be solved in the utility model is to provide a kind ofly gets device spanner for holding in orthopedic spinal nail-stick system.
The technical scheme that this utility model is taked for the technical problem existed in solution known technology is:
Of the present utility modelly get device spanner for holding in orthopedic spinal nail-stick system, comprising: hold and get bar, tapered end and spring leaf; Wherein hold get bar form hold the main body of getting device spanner, tapered end is fixedly installed on the one end of holding and getting bar, and tapered end cross section is hexagon shape and periphery is provided with mounting groove, and spring leaf is fixedly installed in above-mentioned mounting groove.
This utility model can also adopt following technical measures:
Described mounting groove is separately positioned on face pair of parallel in the hexagonal structure of tapered end.
The outer peripheral face of the through tapered end of described mounting groove, spring leaf is " U " type, spring leaf both sides outer width to be greater than in tapered end hexagonal structure two Face Parallel Clearance from.
The advantage that this utility model has and good effect are:
Of the present utility modelly get device spanner in use for holding in orthopedic spinal nail-stick system, the spring leaf be stuck on tapered end in mounting groove inserts six sides in jackscrew in company with tapered end entirety, utilize the rebound effect of spring leaf that spring leaf and six side's inwalls are clamped, thus holding in operation can be completed fast and accurately get jackscrew and pretension process.Structure of the present utility model is simple and hold and get firmly, reduces operation risk, reduces the misery of patient.Owing to being hexagon shape with the tapered end of spring leaf, can hold smoothly and firmly when it inserts six side of jackscrew in pedicle screw and get jackscrew, solve clinical in hold to get in inefficacy or upper nail process and to come off problem, greatly can save operating time, add the probability of successful surgery.
Accompanying drawing explanation
Fig. 1 utilizes the schematic diagram getting device spanner for holding in orthopedic spinal nail-stick system of the present utility model;
Fig. 2 is the axle side schematic diagram for tapered end in orthopedic spinal nail-stick system of the present utility model
Fig. 3 is the schematic diagram for spring leaf in orthopedic spinal nail-stick system of the present utility model.
Detailed description of the invention
Referring to drawings and Examples, this utility model is described in detail.
As shown in Figure 1 to Figure 3, of the present utility modelly get device spanner for holding in orthopedic spinal nail-stick system, comprising: hold and get bar 1, tapered end 2 and spring leaf 3; Wherein hold get bar form hold the main body of getting device spanner, tapered end is fixedly installed on the one end of holding and getting bar, and tapered end cross section is hexagon shape and periphery is provided with mounting groove 4, and spring leaf is fixedly installed in above-mentioned mounting groove.
Mounting groove is separately positioned on face pair of parallel in the hexagonal structure of tapered end.
The outer peripheral face of the through tapered end of mounting groove, spring leaf is " U " type, spring leaf both sides outer width to be greater than in tapered end hexagonal structure two Face Parallel Clearance from, thus utilize interior six sides of spring leaf and jackscrew to block.
Of the present utility modelly get device spanner in use for holding in orthopedic spinal nail-stick system, the spring leaf be stuck on tapered end in mounting groove inserts six sides in jackscrew in company with tapered end entirety, utilize the rebound effect of spring leaf that spring leaf and six side's inwalls are clamped, thus holding in operation can be completed fast and accurately get jackscrew and pretension process.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to this utility model, although this utility model with preferred embodiment openly as above, but, and be not used to limit this utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, certainly the technology contents of announcement can be utilized to make a little change or modification, become the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
