A medical device support system including a central shaft, an extension arm, and a brake assembly. The extension arm has a support for a medical device and a hub at its proximal end mounted to the central shaft for pivotable movement about the central shaft. The brake assembly is secured in the hub for rotation therewith and includes first and second discrete arc shape clamp pieces configured to flex toward and away from each other to respectively increase and decrease a frictional braking force to the central shaft. The hub includes a hub access opening configured to allow passage therethrough of at least one of the arc shape clamp pieces.

Medical device support system having hub access opening

A medical device support system including a central shaft, an extension arm, a brake clamp assembly, and a brake actuator. The extension arm has a support for a medical device and a hub at its proximal end mounted to the central shaft for pivotable movement about the central shaft. The brake clamp assembly is secured in the hub for rotation therewith and includes first and second clamp portions. The brake actuator includes a cap, a plunger coupled to the cap for reciprocable axial movement relative to the cap, and a spring disposed between the cap and the plunger and configured to exert a biasing force against movement of the cap axially toward the plunger. The cap is adjustably mounted to the hub and coupled to the plunger to selectively urge the first and second clamp portions either toward or away from the central shaft to respectively increase or decrease a frictional braking force to the central shaft.

Brake actuator for medical device support system

A medical device support system including a central shaft, an extension arm, and a brake assembly. The extension arm has a support for a medical device and a hub at its proximal end mounted to the central shaft for pivotable movement about the central shaft. The brake assembly is secured in the hub for rotation therewith and includes first and second backing portions and first and second liners supported by the backing portions. At least the first liner is supported by the first backing portion by the first liner being snap-fitted to the first backing portion. The brake assembly includes an actuator configured to flex the first and second backing portions to urge the first and second liners toward and away from each other to respectively increase and decrease a frictional braking force to the central shaft.

Brake assembly for medical device support system

A medical device support system including a central shaft; an extension arm; and a brake assembly. The extension arm has a support for a medical device and a hub at its proximal end mounted to the central shaft for pivotable movement about the central shaft. The brake assembly is secured in the hub for rotation therewith and includes first and second discrete arc shape clamp pieces that are detachably coupled to one another at one end for flexural movement relative to a coupling joint and that are free at an opposite end. The brake assembly includes an actuator configured to flex the first and second clamp pieces relative to the coupling joint toward and away from each other to respectively increase and decrease a frictional braking force to the central shaft.

A brake assembly for braking relative rotational movement of a spindle that is moveable about a central axis relative to a hub. The brake assembly is comprised of a collar comprised of a pair of arcuate leg sections, having a first end pivotally linked together to allow pivoting movement of the leg sections. A frictional surface is provided along the inner surface of each of leg section. An adjustable fastening assembly connects second ends of the leg sections together and clamps the leg sections to the spindle with the frictional surface on the leg sections engaging the outer surface of the spindle. A stop member is connected to the hub and is disposed to engage a surface of the leg sections, wherein rotation of the spindle in a first direction about the axis causes a surface of one of the leg sections to engage the stop and to reduce frictional engagement of one of said leg sections by releasing engagement with the spindle as the spindle moves in said first direction.

Automatically actuated split-collar active mechanical brake for surgical lighting systems

A brake screw for use with a surgical lighting system. The brake screw includes a screw member retained within a threaded aperture of a mounting hub of a spindle of an arm used with the lighting system. The screw member is rotationally adjusted to enable displacement in an axial direction. A brake member is in axial alignment with the screw member and disposed for movement in the axial direction against a mounting tube retained within the mounting hub upon rotational adjustment of the screw member. A rivet section is integrally formed with the brake member and has a distal end retained within an axial recess formed within the screw member, allowing movement of the brake member in the axial direction within the screw member. A bias member is disposed between the screw member and the brake member to create a biasing force that urges apart the screw member and the brake member along the axial direction.
