Abstract
A surgical arm positioning system has a cable including two end portions coupled to a connection member of a hand grip. The cable and connection member form a continuous loop. The surgical arm positioning system further includes a frame that supports a number of pulleys. The continuous loop is trained around the pulleys. The surgical arm positioning system also includes a tensile resistance member engaged with the cable. The tensile resistance member provides tensile force to the cable to resist movement of the continuous loop relative to the frame, thereby to hold the patient's arm relatively still during surgery.
Claims27
A surgical arm positioning system comprising
- a cable having two end portions coupled to a connection member of a hand grip such that the cable and connection member form a continuous loop,
- a plurality of pulleys,
- the continuous loop trained around the pulleys, and
- a tensile resistance member engaged with the cable for providing tensile force to the cable thereby to resist movement of the continuous loop.
A surgical arm positioning system comprising
- two cable portions, an end of each cable portion coupled to a connection member of a hand grip and a frame having a lower assembly and an upper assembly coupled to the cable portions, wherein when a patient's arm is attached to the connection member, the assemblies resist movement to keep the arm stationary and the assemblies move relative to the frame in response to moving a patient's arm.
A surgical arm positioning system comprising
- a cable having two end portions coupled to a connection member of a hand grip such that the cable and connection member form a continuous loop,
- a plurality of pulleys, the continuous loop trained around the pulleys,
- a tensile resistance member engaged with the cable for providing tensile force to the cable thereby to resist movement of the continuous loop,
- a frame,
- a lower assembly and an upper assembly each having one of the pulleys,
- the lower and upper assemblies being adjustable along the frame, and
- a connecting rod fixing the distance between the lower and upper assemblies.
