Description
Technical field
The present invention relates to bender for bone plate tool technical field, especially a kind of folding moulding for Reconstruction plate bending
Curved device.
Background technology
Reconstruction plate generally includes several short cylinder circles, is fixedly connected by connecting bridge between adjacent short cylinder circle, by
It varies with each individual in human skeleton, and the skeletal shape of different parts is had nothing in common with each other, when some complex-shaped positions are fractured such as
Backbone, humerus, pelvis, clavicle, shoulder blade, marrow mortar etc., will usually use Reconstruction plate, be needed when Reconstruction plate uses
Be bent into its shape that matches of fixed bone type, preferably to coincide with bone, and existing connect
Bone plate apparatus for bending is inconvenient for use, and structure is complex, and cost is higher.
Invention content
The technical problem to be solved by the present invention is to：It is inconvenient for use in order to solve bone plate apparatus for bending in the prior art,
And structure is complex, the higher problem of cost, now provides a kind of bending machine moulding for Reconstruction plate bending.
The technical solution adopted by the present invention to solve the technical problems is：A kind of folding moulding for Reconstruction plate bending
Curved device, the Reconstruction plate include several connecting rods and node, and several connecting rods and node alternately connect successively, the folding
Curved device includes the body of rod, sleeve, runner and retainer, and the body of rod is fixedly connected with sleeve, in the runner rotation setting sleeve,
The card slot for placing the Reconstruction plate is offered on the peripheral surface of the runner, the peripheral surface of the runner is along its circumference
If directional spreding has tooth socket, the retainer sliding to be located on sleeve, the retainer is provided with several close to the side of runner
The latch to match with the tooth socket；
The locking mechanism for making runner locking or unlock is provided on the body of rod, the locking mechanism utilizes elasticity member
The elastic force of part makes retainer draw close on runner, and the latch on retainer is made to be meshed with the tooth socket on runner, to realize
The locking of runner, the locking mechanism can be such that retainer is detached with respect to runner under external force, to realize the unlock of runner.
By the way that the node of Reconstruction plate is fastened in card slot the node, it can be achieved that Reconstruction plate in this programme
360 ° of bendings of opposite connecting rod, during bending, since the locking mechanism on the body of rod makes to stop by the elastic force of elastic element
Moving part is drawn close on runner, and the latch on retainer is meshed with the tooth socket on runner, therefore, pull the body of rod can realize the body of rod,
Sleeve, runner and the node that is fastened in the card slot of runner rotate together, by the cooperation of two bending machines, to realize weight
The node of bone plate is built with respect to connecting rod bending, after the body of rod turns an angle, the body of rod, which deflects to, no longer facilitates hand to hold
It holds to continue to rotate and exert a force, at this point, so that it is detached with runner by outer force effect retainer, after retainer is detached with runner,
When pulling the body of rod, runner and its interior node can not together be rotated followed by the body of rod, therefore, can negative side when runner unlocks
To pull the body of rod make its be reset to facilitate hand hold and exert a force so as to continue drive node bending.
Further, the lockable mechanism includes push rod and executes bar, offer on the body of rod the first endoporus and with it is outer
Second endoporus of boundary's connection, first endoporus intersect and are interconnected with the second endoporus, and the push rod is slidably arranged in
In first endoporus, the head end of the push rod extends outward the first endoporus, and the head end of the push rod is fixedly connected with retainer, institute
It states execution bar to be slidably arranged in the second endoporus, it includes using to have inclined contact surface, the elastic element on the execution bar
In push rod being pushed to the first spring that contact of contact surface for executing bar and for pushing execution bar to resist the second bullet of push rod
Spring；
When no external force is applied to and executes on bar, executes bar and resist push rod, the first spring under the action of second spring
In compressive state, push rod pushes retainer, so that the latch on retainer is engaged with the tooth socket on runner, to realize runner
Locking；When external force, which pushes, executes bar, second spring is compressed, since push rod is contacted with the inclined contact surface for executing bar, because
This, the first spring can push push rod that it is made to be contacted with the contact surface for executing bar, that is to say, that push rod can drive retainer thereon
It is detached with runner, to realize the unlock of runner, after human hand, which unclamps, executes bar, it is multiple under the action of second spring to execute bar
Position, push rod push retainer, the latch on retainer are made to be engaged with the tooth socket on runner again.
Further, the contact surface is from top to bottom inclined outwardly, and when pushing up execution bar, executes the contact on bar
Face moves up together, provides the space that push rod is displaced outwardly, push rod is drawn close under the action of the first spring to execution bar, to realize
The unlock of runner.
For the ease of realizing the self-locking for executing bar, further, the tail end of the push rod is outward extended with protrusion, described
Protrusion matches close to one end end face for executing bar with the contact surface for executing bar, described to execute the top for being located at contact surface on bar
Confined planes are provided with, the confined planes are located at the top of protrusion, and the confined planes for executing bar are against by the upper surface of protrusion
Above, it can be achieved that executing the self-locking of bar, prevent execution bar from falling off from the second endoporus.
Specifically, there is step surface, first endoporus to be fixed close to one end end of the retainer on the push rod
There are end cap, one end of first spring to be against on step surface, the other end is against on end cap.
Specifically, one end of the second spring is against the bottom hole of the second endoporus, and the other end is against the top end for executing bar
Portion.
For the ease of clearly grasping the tooth socket on card slot and runner on retainer in locking again after runner unlocks
Whether engage in place, prevent latch, further, spring eye is offered on the retainer, setting is slided in the spring eye
There are contraposition ball, the contraposition ball to be outwardly protruded in spring eye close to one end of runner, the tooth socket fit of the contraposition ball and runner,
It is provided with the contraposition spring for pushing tooth socket to for ball will to be aligned in the spring eye, in the state that runner unlocks, rotates the body of rod
When contraposition ball the sound of " click " can be sent out when often snapping onto in a tooth socket, indicate on the card slot and runner on retainer
Tooth socket face unclamps execute bar at this time, and retainer can engage in place with runner.
For the ease of realizing the bending of node, further, the slot bottom of the card slot is offered for positioning node portion
Locating slot, when position of joints is when in locating slot, the axis of connecting rod is overlapped with the axis of runner.
For handling of the node on Reconstruction plate on the card slot of runner, further, the inner wall of the sleeve
The v notch v being in communication with the outside is offered, the notch extends to lower end surface, the sleeve from the upper surface end face of sleeve
Bottom end there is cylinder bottom, be provided with guide rod on the cylinder bottom, the bottom end end face of the runner offers circle along its circumferencial direction
