Background technology
Owing to do not have special apparatus to fix patient's foot at present, when carrying out knee surgery, need the foot that an operation Physician's Assistant is responsible for immobilized patients specially, this doctor need put the attitude of needs with patient's shank and keep this posture to operation to finish according to the requirement of operation.So not only increased the cost of operation, increased the weight of patient's financial burden, and be responsible for fixed doctor and keep same posture tired easily for a long time, may meet accident in the operation process.In addition, be responsible for that fixed doctor often needs near the patient, especially need the position of having an operation, so also can hinder doctor's operation apparatus of operator, bring many inconvenience to operation.
The utility model content
The technical problems to be solved in the utility model, just provide a kind of simple to operate, use flexibly, reliable, can be at the knee joint gimbal of comprehensive activity of needed scope and locking.
The technical problems to be solved in the utility model, can realize by following technical scheme: a kind of laparoscopic surgery gimbals is characterized in that: comprise following parts:
One support body, support body top are provided with the fixed mechanism, the rear portion that are used for fixing thigh and are provided with and are used for the bindiny mechanism that is connected with operation table;
One shank bearing device is made up of a sole holder of regulating montant and its lower end;
Be fixed with on the described support body before and after towards fairlead, there are and move to axial (length that cooperates patient's lower limb), centre to have the slide in axial hole in the fairlead, one main shaft is enclosed within the slide axis hole rotationally and realizes spinfunction, and described shank bearing device montant top is laterally hinged with at the front end of main shaft and realizes shank swing function;
Between main shaft and slide, also be provided with rotary locking mechanism, between main shaft and shank bearing device montant, also be provided with wobble lock mechanism, on slide, also be provided with the control device of above-mentioned two locking mechanisms.
During operation, patient's leg portion support is fixed on support body and with fixture, patient's lower leg portion support is on the shank bearing device, regulate clockwise or counterclockwise then and rotate to the angle that is fit to perform an operation, adjust shank bearing device montant pendulum angle forward or backward, then by control device control circumvolve lock set kit, the swing retaining mechanism locks respectively, makes patient's thigh and shank put angle in needs.
Described rotary locking mechanism is:
Main shaft is the thin multidiameter in preceding thick back, and cascaded surface is provided with along the equally distributed radial teeth of circumference, and the rear portion of thin axial region is set in the described slide axial hole, thin axial region is middle has radial hole, and this radial hole is a non-round elongated hole in axial direction;
One lock ring gear is enclosed within the thin axial region middle part of main shaft, and lock ring gear both ends of the surface are equipped with along the equally distributed radial teeth of circumference, and its radial teeth towards the main shaft cascaded surface is corresponding with the cascaded surface radial teeth of main shaft, and the lock ring gear has radial first through hole;
