A surgical handpiece system for performing measurement functions and surgical operations. The system includes a handpiece assembly. The handpiece has a handpiece housing and a drive cannula rotatably coupled to the handpiece housing. The drive cannula extends along an axis and is configured to receive torque from a motor. A surgical attachment module has an attachment housing removably coupleable to the handpiece housing. The surgical attachment module has a drive shaft rotatably coupled to the surgical attachment housing and configured to receive torque from the drive cannula to operate an end effector. A measurement module has a measurement housing removably coupleable to the handpiece housing. The measurement module is configured to perform measurement functions associated with operation of the handpiece assembly.

Surgical handpiece system for depth measurement and related accessories

A method of assembling a measurement module used for bore depth determinations in tissue. The measurement module has a housing. A gear having a plurality of gear teeth is disposed within and rotatably coupled to the housing. The measurement module further includes a bushing and a depth extension member having a plurality of rack teeth extending along a depth extension axis. The depth extension member is disposed within a bore of the bushing and the housing. The rack teeth of the depth extension member are arranged to be engaged by the gear teeth of the gear. The depth extension member is urged toward the gear so that the rack teeth are in meshed engagement with the gear teeth. The bushing is fixed to the housing while the depth extension member is urged toward the gear.

Measurement head for a surgical tool

A drill bit comprises a shank extending along an axis and an interface comprising at least one outermost drive portion spaced at a first interface distance from the axis. The drill bit further comprises a resilient arm extending from a proximal end of the shank. The resilient arm comprises an outer arm surface facing away from the axis and a retention surface facing toward a distal end of the shank. The retention surface may be radially aligned about the axis with respect to the outermost drive portion. The resilient arm is movable between: a first position where the outer arm surface is spaced from the axis at a first arm distance greater than the first interface distance, and a second position where the outer arm surface is spaced from the axis at a second arm distance less than or equal to the first interface distance.

Systems and methods for facilitating movement of a patient transport apparatus. The patient transport apparatus has a support structure and a patient support surface. Caster assemblies are coupled to the support structure to roll about a roll axis and swivel about a swivel axis. A control system is configured to control brake mechanisms, steer-lock mechanisms, and pre-swivel mechanisms of the caster assemblies based on one or more inputs.

Patient support cover

A patient support includes a bladder layer with a plurality of bladders, a pneumatic supply system, and a plurality of tubes in fluid communication with pneumatic supply system. The tubes are coupled to and guided by the bladder layer so that the tubes and bladder layer may remain in close registry when being handled, for example, either during the assembly process or cleaning process.

Patient support

A cover for a mattress for supporting a patient is adapted to provide a generally smooth top surface over the mattress while still accommodating the movement of portions of the mattress or changes in thickness of the mattress, for example, when turning the patient.

A patient support for supporting a patient includes a plurality of cushioning layers arranged such that their supporting surfaces when unloaded are generally arranged in a plane, and with each cushioning layer interlocked with each adjacent cushioning layer wherein each cushioning layer provides lateral and longitudinal support to each of its adjacent cushion layer.

A core biopsy device comprises a cutting cannula provided at a distal end with a helical excising blade. The cutting cannula can be rotated within a tissue mass so that the helical excising blade can excise a biopsy sample from the surrounding tissue.

Core biopsy device

An adjustable coaxial needle assembly for placement into a tissue mass prior to a biopsy procedure comprises a guide cannula assembly, a stylet, and a throw calibrator. The stylet is selectively coaxially received by the guide cannula, which is in turn coaxially received by the throw calibrator. The effective length of the guide cannula can be selectively adjusted by moving the throw calibrator relative to the guide cannula to adjust the distance between an open distal end of the guide cannula and a the throw calibrator.

Coaxial needle assembly

A biopsy device includes a housing, a stylet carriage having a strike, a cannula carriage having a strike, and a cocking element comprising a catch carried by a resilient shaft that extends along an operational axis of the biopsy device. To arm the biopsy device, the cocking element is moved in a first arming stroke such that the catch engages the strike on the cannula carriage to deflect the resilient shaft from the operational axis such that the catch clears the strike on the stylet.

Apparatus for cocking a biopsy device

A surgical clip applier for application of surgical clips to body tissue is disclosed. The clip applier includes an elongated housing having proximate and distal ends. This housing also defines a feed surface for the surgical clips. The clip applier also includes first and second jaws extending from the distal end of the housing. The jaws open and close to apply the surgical clips to the body tissue of the patient. A driver is disposed within the housing to advance the surgical clips from the feed surface to the jaws. The clip applier of the present invention incorporates a backing surface extending from the distal end of the housing and extending along the jaws. Accordingly, the backing surface bears against the jaws by constantly applying a force such that the housing is always pre-loaded against the jaws. As such, the jaws are maintained in proper alignment with the feed surface and the surgical clips can be advanced from the feed surface to the jaws without a misfeed.
