Description
Technical field
The utility model relates to the field of medical instrument technology, and in particular to a kind of locking suitable for around femoral prosthesis
Plate.
Background technique
Periprosthetic fracture is the most difficult problem that joint section doctor faces, wherein to consider fracture and joint replacement
Problem, and need to consider the presence of prosthese, sclerotin poor (osteoporosis), nearly joint part and patient's ordinary circumstance in treatment
The problems such as bad (healing problems, internal medicine problem).
The treatment of Periprosthetic fracture will follow accurate reset, stable fixation, soft tissue protection and early functional exercise
Etc. principles, have cerclage, bone support, cable steel sheet and locking steel plate etc. in currently available technology in the selection of implantation material.Cerclage
Good Fracture internal fixaiion cannot be played with bone support, cable steel sheet and locking steel plate can all have biggish risk of breakage, exist
Screw cannot change the disadvantages of direction around prosthesis handle.
A kind of lockplate suitable for around femoral prosthesis is researched and developed in view of the above problems, comprehensive can be looked after above-mentioned several
Point principle solves the problems, such as existing at this stage various.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of lockplates suitable for around femoral prosthesis, can use
In the interior fixation of Periprosthetic Fracture After Total Hip Arthroplasty.
The utility model is achieved by the following technical solution:
A kind of lockplate suitable for around femoral prosthesis, the proximal end including proximal end lockplate and with proximal end lockplate are provided
The connection lockplate being detachably connected, the proximal end lockplate is along its length from proximal end to distally becoming narrow gradually, proximal end
Lockplate is equipped at least one set of oblique three hole in the width direction and is provided along its length the center of circle at proximal end lockplate center
The Universal screw nail hole that line is staggered up and down；The connection lockplate is in its one end far from proximal end lockplate along edge
There is the installation through-hole in spaced apart locking screw thread hole and the button for installing top tape cable hole, and connects in lockplate
Portion offers avoid holes.
Proximal end lockplate with connect lockplate can be by attachment screw dismantling connection, can be used alone proximal end lockplate,
Also it can be used in combination and Periprosthetic fracture be fixed, proximal end locking proximal end is wide, and Periprosthetic can be made to carry out Bicortical-screw
Fixed, distal end becomes narrow gradually, and can reduce the destruction of soft tissue, the inclination bikini round design opened up above, can be resonable
The easier placement screw in the position thought；Locking screw thread hole on connection lockplate is for placing lock screw or nonlocking skin
Matter bone screws, can make fixed more stable, the avoid holes opened up of the entirety of fracture, and guarantee does not influence nail operation when being applied in combination.
Further, minimally invasive by being connected with perpendicular to the fixed link of proximal end lockplate plane on the proximal end lockplate
Diopter.
Minimally invasive diopter leans on dedicated fixed link using the carbon fibre material that can be had an X-rayed under x-ray, diopter and implantation material
Diopter head and implantation material head are fixed together.It is subcutaneously inserted into from fracture proximal end to fracture distal end when operation, through x-ray
After perspective confirmation resets satisfaction, successively it is implanted into fixing screws and completes operation.It can be used in combination with tool, carry out it can minimally invasive
Operation, has widened the functionality of lockplate.
Further, it is connected in the Universal screw nail hole for fixing proximal end lockplate and can be in Universal screw nail hole
The os integumentale screw of universal rotational in 30 ° of circumference.
Proximal end lockplate is fixed by the os integumentale screw in Universal screw nail hole, through design and clinical verification, only
Screw tail portion incisura and the stability of nail-plate cooperation can be only achieved most when the amplitude of oscillation of fixing screws is strict controlled within 30 ° of axial direction
Good state not only can guarantee the screw flexibility fixed to sclerite, but also can guarantee the security and stability of nail-plate cooperation.
Further, it is threaded with locking cap on the top of os integumentale screw in the Universal screw nail hole, it is described
The top surface of locking cap is fixed with the button that may pass through cable.
Locking cap locks os integumentale screw, realizes that multi-shaft locking is two-in-one, cable is worn on button and to fix
It is stronger.Cable is used cooperatively with dedicated cable button, and cable button needs to be mentioned when cable is fixed according to fracture
Before be fixed in locking cap aperture on, determine stablize after by cable pass through button top cable hole, to bundle Periprosthetic
The sclerite that can not be screwed.
Further, top is threaded on the top of os integumentale screw in the Universal screw nail hole open up threading hole
Screw thread button.
Fixed cable is worn in threading hole at the top of screw thread button, cable is passed through to the line on button top according to fracture
Cable hole, the sclerite that can not be screwed to bundle Periprosthetic.
The utility model has the beneficial effects that
One, multiaxis, locking, screw passes through split-type design, it can be achieved that 30 ° of circumference angulations, and can realize lock function, more
Axis locking is two-in-one
Two, pre- moulding is designed using anatomical structure, when femur is fixed, perfection fitting femoral surface.
Three, it can just be fixed in Periprosthetic using Screw.
It four, can engagement tool use progress Minimally Invasive Surgery by the way that minimally invasive diopter is arranged.
Five, lockplate can be used cooperatively cable when being fixed, and intensity is high.
Six, very small bone block can be fixed, screw can be placed in ideal position, screw reseting fracture can be used
It is relocked after block, is applicable to various prosthesis types.
