SURGICAL LIMB POSITIONING AND SUPPORT DEVICE AND METHOD

摘要

A limb positioning and support device for achieving and maintaining reduction of a human bone in connection with surgical procedures involving orthopedic and other surgical fracture tables. The limb positioning and support device includes an articulating and rotating positioning and support arm coupled between a surgical table and a limb saddle. The positioning and support arm is configured to selectively allow translation and/or rotation of the limb saddle in three degrees of freedom. Actuation mechanisms drive the limb saddle vertically and horizontally. A pivot joint coupled between the limb saddle and the positioning and support arm permits rotation of the limb saddle about a vertical axis, and the limb saddle can be angularly displaced about the longitudinal axis of the subject limb. The limb saddle can be positioned and adjusted to bring fractured bone ends into alignment and hold the fracture stationary during the surgical procedure.

主权项

1. A limb positioning and support device comprising:
a mounting device adapted to be rigidly coupled to a surgical patient support apparatus; a limb engaging device configured to engage a limb of a patient; and a positioning and support mechanism coupled between the mounting device and the limb engaging device, the positioning and support mechanism including: a. a moveable end coupled to the limb support device, b. a mounting end coupled to the mounting device, c. a first joint coupled between the moveable end and the mounting end, the first joint configured permit translation of the moveable end along a first path relative to the mounting end, d. a first actuation mechanism selectively operable to drive the moveable end along the first path, e. a first releasable locking mechanism configured to selectively limit translation of the moveable end in at least one direction along the first path, f. a second joint coupled between the moveable end and the mounting end, the second joint configured to permit translation of the moveable end along a second path relative to the mounting end, the second path being different from the first path, g. a second actuation mechanism operable independently of the first actuation mechanism to drive the moveable end along the second path, and h. a second releasable locking mechanism configured to selectively limit translation of the moveable end in at least one direction along the second path.
