A surgical system including a surgical tool and a navigation system for tracking the position of the surgical tool. The surgical tool comprising a housing including a variable speed motor and control module disposed within the housing. The navigation system comprising a navigation console in communication with the control module of the surgical tool, the navigation console may be configured to communicate instructions to the control module of the surgical tool based on the position of the surgical tool relative to a defined zone. The navigation console may be configured to deactivate the surgical tool based on the position of the surgical tool relative to the defined zone. The navigation console may also be configured to provide a user-selectable override option to allow continued operation of the surgical tool within the defined zone.

A powered surgical tool for a user to manipulate a desired tissue in surgical site within a patient may include a body having a tissue manipulation portion powerable and having a manipulation member for manipulating the desired tissue, and a projecting device with an exit port. The projecting device is powerable to emit an optical targeting marker from the exit port in a targeting direction onto the surgical site in a way that is operationally related to the operative direction and is visible to the user for providing information about at least one of a location and an orientation of the manipulation member and an operative direction within the surgical site. An imaging device may be provided to obtaining an image of the surgical site using an optical receiver attached to the body. The device may also measure and/or indicate distance to the surgical site.

Tool holder, in particular a milling cutter holder, which comprises a main body with a substantially oblong cylindrical shape defining a channel in which a transmission passes designed to transmit to the tool, in particular the milling cutter, a movement from the axis of a drive motor, and a gripping element for gripping the tool holder, characterized in that an intermediate part is provided arranged between the transmission and the axis of the drive motor, the intermediate part comprising means for enabling the rotatable connection of said intermediate part to the transmission and the axis of the motor, the intermediate part comprising means forming an abutment designed to lock in translation in the longitudinal direction of displacement of the axis of transmission by abutment in particular against the gripping element.

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.

An apparatus and methods are provided to penetrate a bone and associated bone marrow using a powered driver having a gear assembly and a motor. The powered driver may include an indicator operable to show status of a power supply associated with the powered driver. The power supply may include a battery power pack having a diamond shaped cross section. The powered driver may have a handle with a corresponding cross section.

A handpiece for a handheld surgical instrument having a motor and a heatsink is provided. The motor is within a motor housing and the heat sink is disposed around and thermally coupled with the motor housing. The handpiece is formed from a material having a first thermal conductivity and the heat sink has a second thermal conductivity that is greater in value than the first thermal conductivity of the material of the handpiece. The heat sink is configured to dissipate heat from the motor during operation of the motor to the handpiece.

A method and system for computer assisted orthopedic feedback of at least one surgical object relative a pre-operative plan are disclosed. The pre-operative plan includes a virtual object, which is the virtual representation of the surgical object, and a virtual structure, which is the virtual representation of the patient structure. The method comprises providing the pre-operative plan including planned position and orientation of the virtual object relative to of the virtual structure; obtaining the position of the patient structure based on a surface of the patient structure using a surgical navigation system; obtaining the position of the surgical object using the surgical navigation system; registering the patient structure to the virtual structure and the surgical object to the virtual object; tracking a current position and orientation of the surgical object using the surgical navigation system; and providing feedback of a current position and orientation of the surgical object relative to the planned position and orientation of the virtual object based on the tracked current position and orientation of the surgical object.

A method of performing a surgical procedure with a surgical tool assembly includes inserting a surgical tool into a passage of a patient. The surgical tool can include a main unit and a first rigid sheath. The main unit includes an inner tube that is received within an outer tube. The first rigid sheath removably receives the main unit. The surgical tool can be removed from the passage of the patient, and the first rigid sheath can be completely removed from the main unit. A second rigid sheath having a different shape from the shape of the first rigid sheath can then be removably attached to the main unit instead of the first rigid sheath.

A surgical grip for receiving a handpiece shaft for conjoint rotation therewith and/or for receiving a medical tool in such a way as to transmit torque, includes a carrier sleeve on which at least one coupling component provided for coupling the handpiece shaft is attached such that the at least one coupling component can be brought to a coupled position and to an uncoupled position in the operating state, wherein the at least one coupling component can be brought into contact with an activation unit which is arranged between the carrier sleeve and to an outer actuation sleeve, wherein a rotation securing unit present inside the actuation sleeve acts on the activation unit in a spring-biased manner in the operating state such that the activation unit is held secure against rotation relative to the carrier sleeve.

The present invention relates to an implant system that comprises an implant, a handle configured to removably receive the implant, and, in some embodiments, a spacer tool configured to be mounted on the implant. In further embodiments, a k-wire is employed to guide the implant to a desired location. The handle has a hole for receiving a first portion of the implant. Using the handle to implant the implant, along with an associated spacer, provides a quick and convenient method for implanting the implant as described herein and in the associated drawings.
