A blade housing assembly for a power operated rotary knife including a split blade housing and a cam mechanism for changing a blade housing diameter between blade supporting and blade changing positions. The split blade housing includes an annular blade support section, a mounting section and a split extending through the mounting section and an inner wall of the blade support section and defining a split distance between first and second circumferential ends of the inner wall. The split includes a radial split section and an angled split section adjacent the inner wall. The mounting section includes first and second body portions on opposite sides of the split. The cam mechanism includes a cam plate bridging the first and second body portions and a cam member rotatably supported by the cam plate. The cam member is rotatable between closed and open positions to change the blade housing diameter.

A blade housing assembly for a power operated rotary knife including a split blade housing and a cam mechanism actuatable for changing a blade housing diameter between a blade supporting position and a blade changing position. The blade housing including an annular blade support section, a mounting section and a radially extending split extending through the mounting section and an inner wall of the blade support section and defining a split distance between first and second circumferential ends of the inner wall. The mounting section includes a first body portion and a second body portion on opposite sides of the radially extending split. The cam mechanism includes a cam plate bridging the first and second body portions and a cam member rotatably supported by the cam plate. The cam member is rotatable between a first, closed position and a second, open position to change the blade housing diameter.

A power operated rotary knife having a reusable handle assembly and disposable blade support assembly including a head portion and a blade support portion extending from the head portion, wherein upon completion of a tissue debriding operation on a donor, the used blade support assembly is removed from the handle assembly and disposed of, the handle assembly is autoclaved/sterilized and a new, sterilized blade support assembly is affixed to the handle assembly prior to a subsequent use. The knife includes an attachment assembly to releasably attach the disposable blade support assembly to the handle assembly and a retainer structure positioned in an annular groove formed in a bottom surface of the blade housing portion, the retainer structure bearing against an annular rotary knife blade and the blade housing portion to permanently retain an annular body section of the blade in the annular groove.

A housing for a scale or load cell controller suitable for use in harsh environments. The housing includes a moisture-resistant front display unit coupled to a rear interface and mounting unit. The front display unit includes a front housing, a back housing, and a frame overlying a boundary or seal region between the front and back housings to provide a double moisture-resistant seal between the front and back housings. The front display unit defines an interior region including a display and a plurality of user input keys and controller circuitry. The front display unit is removably attachable to the rear interface unit. A moisture-resistant seal is also provided between the front display unit and the rear interface and mounting unit. The rear interface and mounting unit defines a recessed area supporting a battery pack, a power supply and an interface circuit board. Circuitry in the front display unit is electrically coupled to circuitry in the rear interface and mounting unit via an edge connector circuit card that extends through an opening in the front display unit and mates with an edge connector socket supported in the rear interface and mounting unit.

Helical members applied in flexshaft assemblies for retaining lubricant inside a flexshaft casing. The helical members have a helix that is opposite of a helix of wires that make up a flexible drive member. The helical members direct the lubricant away from an end of the flexshaft assembly that the helix of wires tends to direct the lubricant toward.
