Asymmetric single portal cannula

A protective carrier having a sleeve body with a distal end, a proximal end, and a passageway extending longitudinally between them. One or more elements are disposed in the passageway proximate to the distal end for interlocking with a suture anchor to capture the suture anchor at least partially within the sleeve body. The carrier further includes one or more elements for aligning the sleeve body with a distal portion of a suture anchor driver to inhibit rotation of the sleeve body relative to the driver during and after insertion of the distal driver portion through the passageway.

Protective carrier for suture anchor

A surgical drill assembly is provided having a clutch mechanism that requires a sufficient axial load on cutting surfaces of the drill to enable rotation of the drill. Rotation of the drill ceases almost immediately upon the axial load falling below the predetermined axial load threshold. In one embodiment the drill assembly is disposable, and is virtually impossible to disassemble and reassemble to an operative form. In another embodiment the drill assembly is reusable. The reusable embodiment includes a drill body that enables quick and easy attachment and detachment of a drill head. The reusable drill body is of a unitary construction that can be sterilized and reused without any disassembly.

A pin assembly for use in a skull clamp having a cylindrical non-metallic housing and a metallic rigid pin with a conical point fitted in the non-metallic housing. The non-metallic housing has fingers extending from a cavity in the surface of the housing and are positioned at an angle towards the pin end of the housing to hold the pin assembly in the skull clamp.
