Medical table having controlled movement and method of use
A medical table provides the functionality needed for hip and knee arthroplasty at a cost that is acceptable for smaller patient care centers. Such a table can use a sliding mechanism to maintain traction during positioning of a patient's leg. The table also can utilize a knee arthroplasty attachment to provide for precise knee positioning, such as by using a sliding assembly attached to a spar of the table. The table can include a pair of actuators providing for both lateral tilt and trendelenburg motions, which reduces the complexity from previous tables. The table also can include a removable power/control module, which allows for quick and easy replacement of damaged components.
1. A surgical table apparatus for an arthroplasty procedure utilizing an incision in a patient creating a wound at the hip region of the patient, comprising:
a. a platform for supporting a patient,
b. a base supporting said platform and allowing for adjustment of a position of said platform;
c. a control mechanism said control mechanism including at least one of power components and control components for controlling the position of said platform; and
d. a femoral support device associated with said platform, said femoral support device comprising a femoral support hook to contact the femur and a positioning mechanism configured and operable to adjust the placement of said femoral support hook of said femoral support device, into position in the wound at the hip region of the patient, said positioning mechanism further comprising a motorized positioning mechanism.
2. The apparatus of claim 1 which further comprises a pair of spars rotatably connected to one of the platform and the base, each spar operable to control a position of a leg of the patient.
3. The apparatus of claim 2 which further comprises a traction system coupled to one of said spars, the traction system attachable to a leg of a patient for maintaining traction on the leg, said traction system being slidable relative to a longitudinal axis of said spar during rotational movement of said spar relative to said base.
4. The apparatus of claim 3 in which said traction system includes a locking member for locking the longitudinal position of the traction system on said one spar.
5. The apparatus of claim 2 which further comprises a knee positioning attachment detachably coupled to one of said traction system, said spars knee positioning attachment operable to engage a foot of the patient and having a moveable support member for adjusting an angle of a knee in the respective leg of the patient.
6. The apparatus of claim 1 in which said base supporting said platform includes at least one motor for controlling a position of the platform.
7. The apparatus of claim 1 which further comprises a first motor operable to adjust a vertical position of said platform; and second and third motors, each operatively associated with an actuator, each of said second and third motors operable to control both lateral tilt and trendelenburg tilt of said platform.
8. The apparatus of claim 1 which further comprises a remote control device for activating said control mechanism.
9. The apparatus of claim 1 in which said remote control device comprises a foot pedal.
10. The apparatus of claim 1 which further comprises a jack linked to said femoral hook.
11. The apparatus of claim 10 in which said jack further includes a telescoping member and a motor operating said telescoping member.
