Abstract
The utility model provides a kind of bone holding gasket, including shim body, shim body central part, which is provided with, runs through the through-hole being screwed into for screw, through-hole includes the straight hole section being connected to shim body bottom surface and the inclined hole section being connected to top surface in shim body, and the through-hole diameter of inclined hole section is gradually reduced from top surface in shim body；Shim body bottom surface is the arcwall face of indent, includes at least one circle radial holding tooth for being arranged in shim body bottom surface centered on through-hole on arcwall face.The utility model structure is simple, and the arcwall face of shim body is more bonded with bone face, also has on arcwall face and holds tooth, bone face can be effectively held in by holding tooth, the unsceptered risk that gasket and bone face occur when reducing screw insufficient pressure, improves the success rate of bone surgery, is conducive to Rehabilitation.
Description
Technical field
The utility model relates to medical equipment technical fields more particularly to a kind of bone to hold gasket.
Background technique
In bone surgery, screw is generallyd use across hole gasket and skeletal fixation.Common gasket is generally plane
Structure, surface is without special designing, and when screw insufficient pressure, gasket and bone face handle hold defective tightness, there are unsceptered risk, and spiral shell
It is excessive to follow closely pressure, bone face may be caused to damage, influence normal rehabilitation.
Utility model content
Technical problem to be solved by the utility model is: the deficiency in order to overcome the prior art, the utility model provides one
Kind can effectively be bonded bone face and tightly be held in bone face, reduce unsceptered bone and hold gasket.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of bone holds gasket, including gasket sheet
Body, the shim body central part, which is provided with, runs through the through-hole being screwed into for screw, and the through-hole includes and shim body bottom surface
The straight hole section of connection and the inclined hole section being connected to top surface in shim body, the through-hole diameter of the inclined hole section are pushed up from shim body
It rises and is gradually reduced in face；The shim body bottom surface is the arcwall face of indent, includes at least one circle on the arcwall face with logical
The radial holding tooth for being arranged in shim body bottom surface centered on hole.Bone face can be effectively held in by holding tooth, reduce screw
The unsceptered risk that gasket and bone face occur when insufficient pressure.
Further, in order to improve the intensity for holding tooth, make to hold tooth with good stability, holding tooth is triangular pyramid
Shape bulge-structure, and trigone cone tip part, towards bone face, triangular pyramid bottom surface is fixed with shim body bottom surface.
Further, it holds tooth to be an integral molding structure with shim body, the holding tooth and gasket of integrated formed structure
Ontology facilitates processing, reduces the tie point held between tooth and shim body, is conducive to smooth dispersion screw pressure, make bone face with
Shim body fitting is close.
Further, inclined hole section peripheral side is cambered surface.The inclined hole section of cambered surface design can be screwed into provide and well lead for screw
To facilitating the positioning of screw in operation to tighten.
The utility model has the beneficial effects that bone provided by the utility model holds gasket, central part is provided with to be passed through for screw
The through-hole worn, and the bottom surface of gasket is designed as arcwall face, it is closed convenient for arcwall face and bone face paste, also has on arcwall face and hold
Tooth, bone face can be effectively held in by holding tooth, and the unsceptered risk that gasket and bone face occur when reducing screw insufficient pressure improves orthopaedics
The success rate of operation, is conducive to Rehabilitation.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model optimum embodiment.
1, shim body 2, straight hole section 3, inclined hole section 4, arcwall face 5, holding tooth in figure.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
A kind of bone as shown in Figure 1 holds gasket, is the utility model optimum embodiment, including shim body 1.Gasket sheet
1 central part of body, which is provided with, runs through the through-hole being screwed into for screw, and the through-hole includes the straight hole section 2 being connected to 1 bottom surface of shim body
The inclined hole section 3 being connected to with top surface in shim body 1, the through-hole diameter of the inclined hole section 3 from top surface in shim body 1 gradually
It reduces.3 peripheral side of inclined hole section is cambered surface.The inclined hole section 3 of cambered surface design can be screwed into for screw and provide good guidance, facilitate hand
The positioning of screw is tightened in art.
In actual design, top surface and the junction of gasket outer peripheral surface can be chamfered transition or arc in shim body 1
Transition face transition.1 bottom surface of shim body is the arcwall face 4 of indent, includes that a circle is on the arcwall face 4 centered on through-hole
The radial holding tooth 5 for being arranged in 1 bottom surface of shim body.In order to improve the intensity for holding tooth 5, make to hold tooth 5 with good
Stability, holding tooth 5 is triangular pyramid bulge-structure, and trigone cone tip part is towards bone face, triangular pyramid bottom surface and shim body 1
Bottom surface is fixed.In actual production, it can will hold tooth 5 to be an integral molding structure with shim body 1, the handle of integrated formed structure
It holds tooth 5 and shim body 1 facilitates processing, reduce the tie point held between tooth 5 and shim body 1, be conducive to smooth dispersion spiral shell
Pressure is followed closely, is bonded bone face with shim body 1 closely.
The bone being designed in this way holds gasket, and through-hole can provide good guidance for screw, hand Intraoperative position is facilitated to be screwed into.Arc
Face 4 can make shim body 1 more fit in bone face, hold tooth 5 and be effectively held in bone face, when reducing screw insufficient pressure gasket with
The unsceptered risk that bone face occurs, can effectively improve the success rate of bone surgery, be conducive to Rehabilitation.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims
Property range.
