Abstract: An extended flexible meshed enclosure is arranged between a patient's hand and a grooved support plate upstanding from the associated operating table to support the patient's hand during surgery of the patient's associated limb. To assist in holding the patient's fingers within the meshed enclosure, a hooked and looped strap is wrapped around the patient's finger and surrounding meshed enclosure.

Abstract: An arrangement for attaching PV panels together and to a roofing clamp includes an electrical insulating provision between the attaching arrangement and the roofing clamp.

Abstract: A flat table extension is removably attached to one end of an operating table via a support mechanism that is connected with one of the operating table support legs. The support mechanism includes a pair of support posts, one of which is rotated from a first position parallel with the operating table to a second position lower than the operating table to lower the table extension as required.

Abstract: A dual compression foam pad arrangement for use with surgical postioner devices is formed from a single pair of cloverleaf-shaped foam pieces. The foam piece in contact with the patient is more porous than the foam piece in contact with the positioner support plate for greater patient comfort. A solid plastic connector clip connects the pad arrangement with the surgical postioner support in press-fit relation.

Abstract: A modular surgical patient positioner unit is formed by attaching a plastic linear extension board to a peg board by means of a perforated metal bridging plate. An elongated metal support bar is fastened along one side of the linear extension board for added strength and functionality.

Abstract: In accordance with the invention, a first lever is employed to secure a surgical knee positioner unit to the operating table and a second lever is employed to positionally adjust the surgical knee positioner, per se.

Abstract: A modular surgical patient positioner unit consists of three perforated plastic boards arranged for interconnection together and for attachment to a hospital O.R. table. Two outer boards of similar length and width and a central board of similar width and greater length are employed. When employed with regular-sized patients, the three boards are arranged such that the widths thereof are in alignment. When employed with bariatric patients, the longer central board is rotated perpendicular the other two boards, to provide added width to support the bariatric patient.

Abstract: A simple tibial distraction device includes a simple height-adjustable limb support triangle for positioning a patient's knee during surgery. The triangle includes a slidable support plate for carrying a Steinman pin, as well as a foot support strap to apply traction to the patient's lower leg and/or ankle.

Abstract: A P-CHANNEL MOSFET is configured as a high side switch by arranging a capacitor between the P-CHANNEL MOSFET gate and a pair of push/pull transistors in a control circuit. A pull-up resistor is connected with the high side supply, one leg of the capacitor and with the gate of the P-CHANNEL MOSFET. In a two-phase electrical drive circuit, a pair of P-CHANNEL MOSFETS is connected with the high side supply and a pair of N-CHANNEL MOSFETS is connected with the low side supply.

Abstract: A patient's hip surgery support plate in the form of a posterior sacral support unit is locked to an operating table support frame. A separate anterior pelvic support unit is then positioned over the patient and joined to the sacral support unit via a post extending from the top of the sacral support unit. Both units are movably adjustable in the vertical and horizontal plane to accommodate a wide range of patient sizes for surgery where lateral decubitus positioning of the patient is required.

Abstract: A combined surgical drill and screw guide utilizes a common support cylinder for first guiding the drill guide and then guiding the screw with no auxiliary screw guide insert required.
