Abstract
The orthopaedics of the utility model hexagonal bottle opener, including shank, and for the bar portion at attended operation end, bar portion inside has central through hole, the turret head that bar portion front end has diameter smaller；It is provided with several indicia grooves on the excircle of bar portion stage casing；Shank has the positioning milling plane with centerline parallel, in shank back end outer circumference there is annular groove to provide axially position；Inside center through-hole, which can be sleeved on positioning gram assorted needle, provides fastening guiding, shank positioning milling plane is capable of providing radial limit, and turret head facilitates alignment screw hole, prevents the sideslip that skids in implantation fastener cycle, middle segment mark groove positioning is reliable, and implantation depth is easy to control.
Description
Technical field
The utility model is related to a kind of orthopaedics hexagonal bottle openers.
Background technology
It needs to be connected by screw and fasten implant after drilling in bone surgery, since bone area is generally all smaller, bone
Bone texture material is also brittle, thus Following Orthopaedic Proceduress space is smaller, and connection fastening is difficult, inconvenient for operation, in the prior art
Elevator for orthopedic department easily skid in connecting fastener cycle sideslip, it is not easy to control that connection fastening dynamics, screw are screwed into depth, Bu Nengshi
Answer bone surgery requirement.
Invention content
Technical problem to be solved by the utility model is to provide a kind of positioning reliably, prevents sideslip, implantation depth control
Convenient orthopaedics hexagonal bottle opener.
The orthopaedics of the utility model hexagonal bottle opener, including shank, and for the bar portion at attended operation end, feature exists
In：There is central through hole, the turret head that bar portion front end has diameter smaller inside the bar portion, shank；Bar portion stage casing excircle
On be provided with several indicia grooves；
The shank has the positioning milling plane with centerline parallel, has annular groove in shank back end outer circumference；
There is different colours coating in the indicia grooves.
The orthopaedics of the utility model hexagonal bottle opener, inside center through-hole can be sleeved on to provide to fasten on positioning gram assorted needle and lead
To shank positioning milling plane is capable of providing radial limit, and turret head facilitates alignment screw hole, prevents from beating in implantation fastener cycle
Sliding sideslip, annular groove are capable of providing axially position；Middle segment mark groove positioning is reliable, and implantation depth is easy to control.
Description of the drawings
Fig. 1 is the orthopaedics hexagonal bottle opener planar structure schematic diagram of the utility model embodiment；
Fig. 2 is the hexagon head structure schematic diagram of the utility model embodiment orthopaedics hexagonal bottle opener；
The orthopaedics of Fig. 3 the utility model embodiments positions milling plane structural schematic diagram with hexagonal bottle opener shank.
Specific implementation mode
As shown, a kind of orthopaedics hexagonal bottle opener, including shank 4, and for the bar portion 2 at attended operation end, bar portion 2,
4 inside of shank has central through hole, can be sleeved in bone surgery on preset gram of assorted needle by central through hole, is orthopaedics hand
Screw connection fastening in art provides guiding, and positioning is convenient, and connection fastener cycle is steady, and skidding sideslip will not occur；Before bar portion 2
Holding has the smaller turret head 1 of diameter, and 2 stage casing of bar portion also has step variable-diameter structure, bar portion that diameter constantly reduces, hexagonal
Small, occupied space is few, can adapt to the operation requirement in small space；Shank 4 has the positioning with centerline parallel
Milling plane 6, positioning milling plane 6 can be fixed with the positioning shoulder respective outer side edges of respective shapes on fixed chuck, to radial rotation
Capable limit is rotated into, convenient for tightening implantation attachment screw, prevents the sideslip that skids in connection procedure, axially position effect good；After shank
Holding, there is annular groove, the annular groove that shank rear end is circumferentially arranged limit can be cooperatively formed with fixed chuck on excircle
Structure improves axial dimensional accuracy in surgical procedure；It is provided with several indicia grooves 3, indicia grooves on 2 stage casing excircle of bar portion
There is different colours coating in 3, connection depth is implanted by different colours coated marker difference, intuitive is high, size for connection control
System is convenient, and positioning is reliable, simple in structure, easy to operate.
The orthopaedics of the utility model hexagonal bottle opener, overall length 114mm, shank length are 25mm, position milling plane length
For 16mm, inside center through-hole diameter can go 1.~1.3mm of selection, and the present embodiment chooses 1.2mm, so as to a diameter of 1.1mm
Guide pin can easily pass through；It is followed successively by 2mm, 2.8mm, 4.8mm from turret head, reducer to shank body radial dimension, six
Angle head length dimension is 5mm, and reducer length dimension is 32 mm；It manufactures in process by drawing, turret head junction
For R2.5mm, reducer is 135 ° with shank body chamfering, other chamferings are by 0.3X45 ° of processing, material heat treatment process
HRC48 °~52 °, and by electrolysis, Passivation Treatment；Dimensional tolerance is according to GB/T1804-m standard productions.
The orthopaedics of the utility model hexagonal bottle opener, inside center through-hole can be sleeved on to provide to fasten on positioning gram assorted needle and lead
To shank positioning milling plane is capable of providing axially position, and turret head facilitates alignment screw hole, prevents from beating in implantation fastener cycle
Sliding sideslip, middle segment mark groove positioning is reliable, and implantation depth is easy to control.
