Description
Technical field
This utility model relates to a kind of medical artificial joint prosthesis replacement operation apparatus, particularly a kind of tibia holder erector.
Background technology
Knee joint is one of the most complicated joint of human body maximum, structure, is topmost joint in the human motion process.The development of knee joint prosthesis system is apart from the history of existing decades of the present, when human body natural's knee joint causes part or all of afunction owing to reasons such as pathological changes or damages, just need to adopt knee joint prosthesis system to be replaced, to rebuild the knee joint normal function, reduce the ailing and inconvenient of patient, implement the knee joint prosthesis system replacement and can reach best therapeutic effect, can recover patient's ability to act to greatest extent.
Knee-joint prosthesis is divided into fixed platform type knee-joint prosthesis and rotation platform type knee-joint prosthesis, fixed platform type knee-joint prosthesis comprises femoral prosthesis and fixed platform prosthese (being also referred to as the tibial plateau prosthese), femoral prosthesis is connected with distal femur by stem or screw or bonding way are installed, the fixed platform prosthese comprises tibia holder and tibia pad, the tibia holder is installed in proximal tibia, the tibia pad then is arranged between femoral prosthesis and the tibia holder, and be fixedly mounted in the tibia holder, tibia pad upper end matches with the articular surface of femoral prosthesis lower end, is used for simulating normal human body natural's motion of knee joint process.
Though the tibia pad is fixedly mounted in the tibia holder, but having trace between the possible contact surface moves, therefore generally still higher surface smoothness requirement can be arranged to the contact surface of tibia holder, and the tibia holder must rely on external force to implant, and therefore must use specific purpose tool: tibia holder erector.Because tibia holder specification is more, and existing tibia holder erector as: cut to step the full knee joint of the NEXGEN system of (Zimmer) company, the full knee joint of the SCORPIO system like instrument of Shi Saike (Stryker) company only can be adjusted along the tibial plateau fore-and-aft direction, form at 2 and fix, therefore not very good to the clamping location of tibia holder.
The utility model content
The purpose of this utility model is to provide a kind of above-mentioned shortcoming that overcomes, the tibia holder erector that clamping is solid and reliable.
The technical scheme that realizes this utility model purpose is: a kind of tibia holder erector, have the erector body, and erector body upper end is provided with extension bar, the lower end is provided with back clamping foot, and the middle part is provided with adjusting screw(rod), and adjusting screw(rod) passes the erector body, the rear end is provided with handle, clamping foot before front end connects; Be provided with contiguous block between described adjusting screw(rod) and the preceding clamping foot, contiguous block and adjusting screw(rod) front end are rotationally connected; Preceding clamping foot has left front clamping foot and right front clamping foot, and left front clamping foot and right front clamping foot are separately positioned on the left and right two ends of contiguous block, regulate its left and right position respectively by left adjusting screw(rod) and right adjusting screw(rod).
The contiguous block left and right sides end face of above-mentioned tibia holder erector is equipped with the axis of guide, the axis of guide passes left front clamping foot and right front clamping foot, make left front clamping foot and right front clamping foot be slidingly arranged in the contiguous block left and right sides, and regulate its left and right position respectively by left adjusting screw(rod) and right adjusting screw(rod).
Be respectively equipped with spring top bead on the left front clamping foot of above-mentioned tibia holder erector and the right front clamping foot, equidistantly be provided with some pits on the described axis of guide, spring top bead and groove position match.
The utlity model has following characteristics: the clamping foot had left and right two before (1) was of the present utility model, and can adjust the position respectively, can form 3 clampings, and clamping is solid and reliable; (2) the be in course of adjustment cooperation of spring top bead of clamping foot can have tangible feel prompting before about this utility model, and is easy to operate, has higher utility.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, this utility model is described in further detail, wherein
Fig. 1 is this utility model schematic perspective view;
Fig. 2 is this utility model cutaway view.
The specific embodiment
(embodiment 1)
