A retractor in accordance with embodiments of the invention comprises a retractor element and a retractor arm releasably connectable to the retractor element. A first connector structure on the retractor arm includes a first end portion having a first edge, a first pin slot extending into the first end portion from the first edge, and a first lock well in the first pin slot. A second connector structure on the element includes an end portion having an aperture, the end portion configured to receive the first connector structure at a connected position with the aperture aligned with the first lock well of the first connector structure. The lock includes a first cam and is rotatable between a release position and a lock position. The cam is configured such that (1) when the lock is in the release position the end portion of the second connector structure can be moved to the connected position with respect to the first connector structure with the first cam passing through the first pin slot and into the first lock well of the first connector structure, and (2) when the lock is in the lock position the first cam engages the first end portion of the first connector structure to resist withdrawal of the first end portion of the first connector structure from the second connector structure.

Spinal retractor with releasable arms

A retractor in accordance with embodiments of the invention includes an adapter and an arm that can be releasably connected to the adapter. An end portion of the arm includes first and second legs and a lock well between the legs. The adapter includes a tubular channel having side walls configured to receive the end portion of the arm, and a lock having a cam in the channel that is rotatable between a release position and a lock position. The lock is configured such that (1) when the lock is in the release position the end portion of the arm can be inserted into the channel and removed from the channel with the cam passing to and from the lock well between the legs, and (2) when the lock is in the lock position the cam is in the lock well and engages the legs to urge the legs into engagement with the side walls of the channel.

Sternal retractor with releasable arms having cam locks

A hearing aid includes a relatively rigid shell which holds hearing aid electronics and one or more flexible, shape-retaining filaments attached to the hearing aid shell. The filament(s) extend(s) out a proximal side of the hearing aid shell having a shape which interacts with the user's ear anatomy such as the conchae bowl. The shape determines an insertion depth of the hearing aid shell into the user's ear canal, and a spring action biases the hearing aid toward the desired insertion depth. The hearing aid supported by the filament(s) provides an open, unoccluding position in the ear canal.
