  • Publication number: 20190175241
    Abstract: A control module for a powered surgical tool. The module includes a shell. Internal to the shell is a circuit for controlling the power generating unit of the tool with which the module is associated. Conductive pins extend through the shell to provide electrical connections to the components within the shell. Active seals are disposed around the conductors and the inner walls of the shell that define the openings in which the pins are seated. Each active seal include an inner and outer skirt. A biasing component disposed between the skirts urges the inner skirt against the section of the conductive pin seated in the opening. The biasing component also urges the outer skirt against the adjacent opening-defining inner wall of the shell. The active seal functions as a barrier between the conductive pin and the adjacent inner wall of the shell.

  • Patent number: 10314633
    Abstract: A system for augmenting a bone structure. A shape memory device includes a deflectable distal segment including temperature-dependent memory metal material. The shape memory device is slidably received within a guide cannula. The deflectable distal segment may include a substantially longitudinally straightened form, such as when subjected to a force from the guide cannula. The deflectable distal segment forms a first deflected shape having a first bend away from said straight longitudinal axis at a first elevated temperature greater than an initial temperature, and forms a second deflected shape having a second bend away from said straight longitudinal axis at a second elevated temperature greater than said first elevated temperature. The shape memory device may create voids within the bone structure with the deflectable distal segment at the first and/or second bends. Methods for positioning a shape memory device within a bone structure are also disclosed.

  • Publication number: 20190151531
    Abstract: A lavage unit may include a handpiece configured to house a pump to which an irrigation tube is connected. The pump may include a bellows defining a pump chamber. When the bellows is reciprocated by a linkage, the bellows draws irrigation fluid from the irrigation tube into the pump chamber and then discharges the fluid out of the pump chamber through an outlet. The pump further includes a section formed from compressible or flexible material that defines a supplemental chamber. The linkage is connected to said pump to alternatively compress the bellows forming the pump chamber and the material forming the supplemental chamber. During the movement of the linkage a valve located between the pump chamber and the supplemental chamber reciprocates with the linkage.

  • Patent number: 10292877
    Abstract: A patient transport apparatus for moving a patient from one location to another. The patient transport apparatus comprises a suspension system to limit discomfort to the patient when the patient transport apparatus moves over disturbances in floor surfaces. The suspension system comprises suspension devices such as a spring and/or a damper. The suspension system is operable in an energy-absorbing mode in which the suspension system absorbs energy as wheels move over the disturbances during transport or a lockout mode in which the suspension system is relatively more rigid as compared to the energy-absorbing mode. A control system operates to place the suspension system in one of the modes.
