A system for cutting a bone of a patient may include a motor; a rotating shaft drivingly coupled to the motor; a support tube positioned around the rotating shaft and supporting the rotating shaft at a plurality of locations; a plurality of steering wires coupled to the support tube; and a bone cutter at a distal end of the rotating shaft.

A battery pack for a use with a powered surgical tool. The battery pack may include a housing with an outer wall and opposing first and second ends. The housing may include an elongated shape that extends between the first and second ends. A first member may extend across the first end of the housing and include a first aperture, and a second end member may extend across the second end of the housing and may include a second aperture. A passage may extend through the housing with a first end that aligns with the first aperture and a second end that aligns with the second aperture. The housing may be sized for a plurality of storage locations positioned between the first and second members and around the passage, and each of the storage locations may be configured to store a power cell.

Disclosed is a system to engage a plurality of tools. In the system a drive shaft and collet may be assembled to engage and disengage, selectively, a plurality of tools. User selection may allow use of a plurality of tools during a procedure or during a plurality of procedures.

A swivel knuckle assembly for interconnecting a motor and a supply line. The knuckle assembly may include a bearing member to reduce a coefficient of friction. A locking mechanism is disclosed to connect members of the knuckle assembly.

A bone fusion system including a collection vessel, an abrading and harvesting device, tubing and a probe. The abrading and harvesting device includes a needle portion and a sharpened tip. The needle portion has a central bore extending therethrough. The needle portion has a distal end. The sharpened tip is attached to the distal end of the needle portion. The tubing is operably connecting the collection vessel and the abrading and harvesting device. The probe has a threaded portion and a tip portion at a distal end of the threaded portion. The threaded portion has a thread on an outer surface thereof. The tip portion is unsharpened and does not have a thread on an outer surface thereof. The probe is extendible through the central bore.

A rotary valve includes a rotor housing having a first centrally-located aperture extending axially through the rotor housing, an inlet port, and an outlet port. The inlet port and the outlet port each extend radially and open into the first centrally-located aperture. The rotary valve further includes a rotor to be disposed within the first centrally-located aperture. The rotor includes a main body and a dwell space extending radially inwardly into the main body and circumferentially around a portion of the main body. The rotor further includes a second centrally-located aperture that extends axially through a distal end of the rotor and into the dwell space within the main body.

A surgical instrument system including an endoscope having an elongated housing extending between a proximal instrument end and a distal instrument end. The surgical instrument system may further include an irrigation sleeve having a sleeve body extending between a proximal sleeve end and a distal sleeve end. The irrigation sleeve may further have a first lumen and a second lumen spaced out of fluid communication with the first lumen, the first lumen formed in the sleeve body for receiving at least a portion of the elongated housing of the endoscope with the distal instrument end arranged adjacent to the distal sleeve end. The second lumen may be formed in the sleeve body and extend between a lumen inlet adapted for fluid communication with an irrigation source and a lumen outlet arranged to direct irrigation fluid toward the distal instrument end.

A method of fabricating an ultrasonic medical device is presented. The method includes machining a surgical tool from a flat metal stock, contacting a face of a first transducer with a first face of the surgical tool, and contacting a face of a second transducer with an opposing face of the surgical tool opposite the first transducer. The first and second transducers are configured to operate in a D31 mode with respect to the longitudinal portion of the surgical tool. Upon activation, the first transducer and the second transducer are configured to induce a standing wave in the surgical tool and the induced standing wave comprises a node at a node location in the surgical tool and an antinode at an antinode location in the surgical tool.

A portable and passive safety intraosseous device to allow for direct introduction of medications, etc., within the intermedullary space of a subject patient's bone or, if needed, the removal of certain substances from such a subject patient's bone. Such a device permits direct drilling and placement of a cannula within the subject bone with access external to the subject patient's skin, permitting, as well, connection of a tube for such introduction/removal purposes. The ability to provide a passive safety unit allows for facilitated utilization in, for instance, emergency situations with the entire device provided for utilization thereof. The device includes a drilling component with a permanently attached stylet and a removable cannula, a power supply for a single drilling operation, a mechanism to draw the stylet back into the drill component after use and disengagement from the cannula, and an automatic closure that activates with the separation of the cannula.

An intraosseous access system to access a medullary cavity includes a driver including an access assembly, a motor, and an energy source. The intraosseous access system further includes a sensor configured to detect a first input from one of the motor or the energy source. The intraosseous access system further including a processing unit, communicatively coupled with the sensor, configured to receive the first input from the sensor, and determine access to a medullary cavity. The processing unit can then modify operation of one of the motor and the energy source to automatically stop operation of the system and prevent backwalling.
