6520976, Feb 18, 2003

Filed:

Apr 30, 1999

Appl. No.:

09/303781

Inventors:

Gary B. Gage - Arlington TX

Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

A61B 1732

US Classification:

606170, 606180

Abstract:

Devices and methods are described to rapidly and easily install a control device in a resecting tool system. The motor portion of the resecting tool can be readily separated from the air conduit to which it is attached. In a preferred embodiment, modular hand-operated control is then inserted between the air conduit and motor and interconnected with both components. The modular hand-control provides a housing with an actuatable lever, or handle, which controls an internal valve assembly.

Appl. No.:

10/304254

Inventors:

Gary W. Gage - Grand Prairie TX

Assignee:

Koch-Glitsch, LP - Wichita KS

International Classification:

B01F 304

US Classification:

2611145, 202270

Abstract:

A vapor-liquid contact tray is provided with a quick opening manway. The manway includes an opening formed in the tray and an overlying cover formed by a pair of panels joined together by a center hinged connection. The cover panels of the manway have upturned flanges formed along the lateral margins of the cover. The flanges are removably received within inverted U-shaped brackets that are positioned along the lateral margins of the tray adjacent the manway opening. When the cover is closed, the flanges are received tightly within the associated brackets to secure the lateral margins of the cover to the tray. The cover can be opened by lifting one or both cover panels to cause them to fold together about the center hinge. As the cover panels are lifted, the flanges tilt within the brackets and are released from engagement therewith. The end margins of the cover panels are secured to the adjacent portions of the tray by conventional manway clamps.

Gary W. Gage - Grand Prairie TX, US

Assignee:

Koch-Glitsch, LP - Wichita KS

International Classification:

B01F 3/04

US Classification:

2611141, 2611145

Abstract:

A mass transfer column () is provided with at least one vapor-liquid contact tray () that is disposed within the open internal region () defined by a shell () of the column (). At least one expansion ring () underlies and supports the vapor-liquid contact tray (). An expander () is associated with first and second end segments () of the expansion ring () that define a cutout () in the expansion ring (). The expander () includes brackets () welded to the end segments () and a threaded member () that extends through the brackets () and carries nuts (). Turning the nuts () against facing surfaces of the brackets () causes the first and second end segments () of the expansion ring () to be forced apart to cause an increase in the circumference of the expansion ring (), thereby sealing the expansion ring () against the inner surface of the column shell. At least one seal plate () is positioned on the threaded member () to block the cutout () in the expansion ring () Rods () extend between the expansion ring () and a support ring () that is welded to the column shell () to transfer a portion of the load carried by the expansion ring () to the support ring ().

Medtronic, Inc. - Minneapolis MN

International Classification:

B23B 3120
A61B 1732

US Classification:

279 50

Abstract:

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.

International Classification:

A61B 1720

US Classification:

604 22

Abstract:

A disposable irrigation device for a motorized surgical tool comprises a cannula with a cylindrical clip bonded near one end. The clip has a C-shaped cross-section with a slot. Both the cannula and the clip are formed from malleable material which may be manually formed into a resilient desired shape. The surgical tool has a rotatable tool implement extending from a cylindrical guide member. The device is attached to the tool by inserting the guide member into the clip so that one end of the cannula is located near the implement. The malleable clip clamps around and frictionally engages the guide member. The malleable cannula may be bent to precisely direct the flow of irrigation fluid relative to the implement. For implements of greater length, the device may be inverted and attached in the opposite direction.

Assignee:

Midas Rex, L.P. - Fort Worth TX

International Classification:

A61B 1756

US Classification:

606 80

Abstract:

A surgical tool for resecting bone has a pneumatic motor within a tool body which rotates a coaxial tool implement. The tool implement is provided with irrigation fluid from a fluid reservoir. The reservoir and the motor are charged with pressurized air from a pressurized air source. A fluid control valve is located between the reservoir and the tool, and an air control valve is located between the air pressure source and the motor. The air control valve is controlled by a variable foot pedal or hand valve so that the speed of the motor is variably actuated by the foot valve.

Assignee:

Midas Rex L.P. - Fort Worth TX

International Classification:

A61B 1700

US Classification:

606 79

Abstract:

A surgical instrument has a motor which rotates a tubular shaft about an axis. The shaft drives an implement and has an aperture which contains a ball. When the implement is installed, the ball extends through the aperture to engage the implement and lock it in. The tool has an actuation sleeve which is axially movable between locked and released positions for engaging and disengaging the ball to the implement. The actuation sleeve has an axial slot and a safety sleeve located radially outward from the actuation sleeve. The safety sleeve has a pin which extends radially inward and a cylinder extending radially outward. The cylinder contains a ball which is biased inward. The outer surface of the tool has a pair of detents for receiving the ball. The safety sleeve has locked and unlocked positions. In the unlocked position, the pin is aligned with the slot and the ball engages the first detent to permit the actuation sleeve to move between the locked and released positions.
