A control device for a surgical power tool. The control device including a housing, an input element located on the housing, and a control unit. The housing configured to couple to a surgical power tool. The input element located proximate the top of the housing and configured to receive a user input. The control unit located within the housing, where the control unit sends user input information received at the input element to the surgical power tool.

A surgical file instrument comprising a file, file guide, an outer split casing, a motion converter converting rotary motion to reciprocal motion and file assembly. The file assembly consists of an angular shaped elongated tube fairing into a generally flat portion defining the guide for the blade of the file, a complementary shaped file and a plastic rod insert having a lumen for the file and a lumen defining a passage for flowing a fluid to the surgical site. The motion converter consists of a planetary gear system connected to the battery powered motor that rotates a platen which in turn drives a cam and cam follower fitted into the cam slot for driving a drum for producing rectilinear motion. The file assembly is attached to the drum for reciprocating the file blade for use in a medical procedure for removing bone or a portion thereof.

A filtration system for collecting bone fragments during surgery performed on a patient includes a cylinder having a rotating disk with circumferential arms extending radially in the cylinder to define pockets. The rotating disk includes a longitudinal hub that carries an outlet connected to a central passageway formed in the disk. A plurality of apertures on the disk permit the liquid to flow into the passageway and through the outlet while the pockets retain the bone fragments. The disk is rotated to align circumferential spaced pockets to align with the inlet and outlet ports. The disks includes bearing surfaces that permit the rotation thereof and the arms are spaced from the cylinder inner surface to allow the flow of fluid in the event the pockets fill and clog the apertures and prevent flow into the outlet passage.

Bone fragment collector

A seal for an attachment to a surgical motor is provided by cutting threads into the inner surface of the nose cone of the attachment whereby the helical wound threads are in a direction opposite to the direction of the rotating shaft of the instrument being supported by the attachment. The motor can likewise by configured to define a seal where an attachment is not being utilized.
