Patent number: 6209886Abstract: A resecting tool contains a rotatable chuck inside a base for engaging the drive shaft of a motor. The chuck extends into a tubular casing that has an outer actuator sleeve. The sleeve is limited to rotation relative to the casing and is used to move a pair of locking elements or balls in separate helical slots in the casing. Each ball is seated in a collar that abuts a collet receiver inside the casing. During implement changeover, the collar abuts the collet receiver and acts as a brake to prevent accidental actuation of the chuck of the tool. The collet receiver is spring-biased into contact with a first collet which closely receives a tool implement within the resecting tool. The sleeve is used to manipulate the collet to clamp onto and unclamp the tool implement. A collet coupling is located on the front end of the casing and has a collet nut on its forward end. The collet nut houses a second collet with a serpentine cut for engaging and retaining a guide sleeve for supporting the tool implement.Type: GrantFiled: April 30, 1999Date of Patent: April 3, 2001Assignee: Medtronic, Inc.Inventors: Larry Dale Estes, Ray E. Umber, Gary B. Gage

Patent number: 5893851Abstract: A coupling device attaches to a surgical resecting instrument with a motorized shaft for rotating surgical implements. The device houses a primary shaft which can be directly attached to the motorized shaft, and a secondary shaft which can be attached to the primary shaft through a hexagonally-shaped drive attachment with a bore. The primary shaft has several apertures with balls that engage an annular recess in the shank of a first implement to restrict its axial movement. The primary shaft also has a torque shoulder for engaging a torque shoulder on the first implement. If the first implement is removed, the secondary shaft can be installed to receive a second implement with a diameter smaller than that of the first implement. The secondary shaft also has several apertures with balls that engage an annular recess in a second implement shaft to restrict axial movement. The secondary shaft has axially spaced apart torque shoulders for engaging a torque shoulder on the second implement.Type: GrantFiled: April 18, 1997Date of Patent: April 13, 1999Assignee: Midas Rex Pneumatic Tools, Inc.Inventors: Ray E. Umber, Larry Dale Estes, Townesend R. Scantlebury

Patent number: 5782836Abstract: A pneumatic surgical tool for cutting bone during surgical procedures includes a pneumatic motor having a rotary shaft, a resecting tool having a cutting element rotated by the motor, a sleeve to surround and support the resecting tool, anti-friction bearings for further rotatably supporting the resecting tool, and a chuck for connecting the resecting tool to a spindle of the rotary shaft. The motor housing, rotor, spindle, and chuck are created from titanium. The bore of the housing and the cutting tip of the resecting tool have thin hard metal cases, such as titanium nitride, titanium aluminum nitride, or titanium carbon nitride.Type: GrantFiled: July 30, 1996Date of Patent: July 21, 1998Assignee: Midas Rex Pneumatic Tools, Inc.Inventors: Ray Umber, Durrell G.

Patent number: 5741263Abstract: A coupling device attaches to a surgical resecting instrument with a motorized shaft for rotating a surgical implement with at least one torque shoulder. The device houses a tubular shaft with a central bore which attaches to the motorized shaft through a hexagonally-shaped drive attachment with a bore. The tubular shaft has several apertures with balls that engage an annular recess in the implement shaft to restrict axial movement. The tubular shaft has axially spaced apart torque shoulders capable of engaging torque shoulders on implements of different size diameters or multiple diameters. The tubular shaft is also capable of driving an implement with axially spaced apart torque shoulders.Type: GrantFiled: April 18, 1997Date of Patent: April 21, 1998Assignee: Midas Rex Pneumatic Tools, Inc.Inventors: Ray E. Umber, Larry Dale Estes, Townesend R. Scantlebury
