The How It Works of this Three Degree Of Freedom serial-parallel mirror arthroplasty operating robot is:
During operation, doctor robot being arranged on the side of operation table, patient is placed on bed.Robot can be in conjunction with three
Dimension image-guidance technology, is guided by image and determines the position of cutting head 510 in abrasive drilling mechanism of robot 5, by computer control
System becomes preoperative grinding planned trajectory into driving pulse, drives vertical mechanism 2 and the servomotor of two horizontal mechanisms 4,
Convert rotational motion is the ball nut linear motion along ball screw by V belt translation by servomotor, as whole robot
Input motion, the pose of robot is different in constantly change along with the startup time of each motor, preoperative grinding planned trajectory
Export to the movement locus of cutting head 510, complete the bone excision on movement locus.Robot solves owing to relying on doctor
Experience and the operation risk that brings, greatly reduce the working strength of doctor, thus improve operation precision.
Vertical slide unit 214 or horizontal sliding table 413 by driven by servomotor move along a straight line along guide rail, complete sharpening machine
Upper and lower, the Linear Driving function of plane of structure 5.The counting zero point of incremental encoder is set in the initialization procedure of robot,
Arrange positive and negative spacing to ensure the sports safety of robot in the stroke range of vertical slide unit 214 or horizontal sliding table 413.Two
In individual limit sensors, one is played effect that is spacing and that arrange zero-bit, the effect of another limited location.Linear mechanism is without accumulation
Error, precision is higher, runs mild, and working space is big, and security is high, and in joint replacement operative space, realization needs
Motion.
The principle of this Three Degree Of Freedom serial-parallel mirror arthroplasty operating robot is:
Both sides linking arm 3 and two horizontal sliding tables 413 by slide unit 214 vertical in vertical mechanism 2 form triangular structure,
Wherein vertically the lifting positioning of mechanism 2 forms the free degree of a series connection, the mutual translation of two horizontal sliding table 413 linear extendibles
Positioning forms two frees degree in parallel.Thus vertically the lifting of mechanism 2 and the translation of horizontal mechanism 4 combine, and reach three-dimensional space
Action of arbitrarily transposing between, finally realizes abrasive drilling mechanism 5 by the bone cutting operation of given trace.Full symmetric parallel machine
Structure has preferable isotropism, and perseverance is rigid triangle mechanism, and rigidity is high, and bearing capacity is big, is suitable to need bigger cutting force
Bone grinding occasion.
