Patient-receiving surgical device

Abstract

A limb-positioning device is adapted for use in an operating room and is attachable to an operating room table. The limb-positioning device includes a full motion arm, a patient-receiving surgical device and a tension controller. The full motion arm has a plurality of pivotally connected arms with a plurality of joints therebetween. One end of the full motion arm is adapted to be attached to an operating room table. The patient-receiving surgical device is attached to a block joint at the distal end of the full motion arm. There is a tension controller for each joint. Preferably the tension controller concurrently controls the tension in each joint. The patient-receiving surgical device may be a forearm tray, a lower leg tray, a distraction harness or a Chinese finger trap assembly. There is provided a method of using the limb-positioning device. In addition, a patient-receiving surgical device includes a patient-receiving portion and a bar attached thereto. The bar is attachable to a receiving channel on an attachment block that is attached to a ball joint at the distal end of a full motion arm of a limb-positioning device.

         12 . A limb-positioning device as claimed in  claim 8  wherein the patient-receiving surgical device is Chinese finger trap assembly.  
     
     
         13 . A limb-positioning device as claimed in  claim 3  wherein the patient-receiving surgical device is detachable.  
     
     
         14 . A limb-positioning device as claimed in  claim 3  wherein the patient-receiving surgical device is a forearm tray.  
     
     
         15 . A limb-positioning device as claimed in  claim 3  wherein the patient-receiving surgical device is a lower leg tray.  
     
     
         16 . A limb-positioning device as claimed in  claim 3  wherein the patient-receiving surgical device is a distraction harness.  
     
     
         17 . A limb-positioning device as claimed in  claim 3  wherein the patient-receiving surgical device is Chinese finger trap assembly.  
     
     
         18 . A method for positioning a portion of a patient's anatomy comprising the steps of: 
 providing a limb-positioning device comprising a full motion arm having a plurality of pivotally connected arms with a plurality of joints therebetween and one end of the full motion arm being adapted to be attached to an operating room table, a patient-receiving surgical device attached to a block joint at the distal end of the full motion arm, and a tension means for controlling the tension of each joint;    attaching the limb-positioning device to an operating room table;    adjusting the tension means;    securing the portion of the patient's anatomy on the patient-receiving surgical device;    positioning the patient-receiving surgical device; and    tightening the tension means.
