A surgical system which may include a controller, a data entry device, a powered surgical handpiece and a surgical tool adapted to couple to the surgical handpiece. The surgical handpiece can include motor direction control and feedback, safety stop features, stimulation and nerve integrity monitoring, a tool connector assembly configured to retain a variety of surgical tools and optional navigation and/or electric ratcheting features.

A surgical cutting instrument for use with a drive motor, and related system and method, is described. The surgical cutting instrument includes an elongated drive member, a cutting tip secured to the drive member, a non-conductive coupling body adapted for connection to a motor assembly, a housing maintaining the coupling body, a fluid coupling assembly and an electrical connector for connection to a stimulating energy source. The electrical connector is in electrical communication with the cutting tip via an electrical pathway.

Instrument and system for surgical cutting and evoked potential monitoring

A surgical cutting instrument for use with a drive motor, and related system and method, is described. The surgical cutting instrument includes an elongated drive member, a cutting tip secured to the drive member, a non-conductive coupling body adapted for connection to a motor assembly, a housing maintaining the coupling body, and an electrical connector for connection to a stimulating energy source. The electrical connector is in electrical communication with the cutting tip via an electrical pathway.

A surgical fixation device for mounting a stereotactic reference frame to a patient. The device includes a mounting bracket assembly, a cannulated post, a base, an anchor tube, a plurality of percutaneous pins, and a driving device. The mounting bracket assembly is connected to a top portion of the post, whereas the base is slidably coupled to a bottom portion of the post, and defines a plurality of legs. The anchor tube extends distally from the post. The percutaneous pins extend distally from the legs, respectively. Finally, the driving device is connected to the post and is adapted to selectively contact the base. Upon final assembly, the base is longitudinally moveable relative to the anchor tube. The base can be moved to a retracted position such that the anchor tube is readily securable to a bony structure of the patient's anatomy. Once secured, the base can be moved distally such that the percutaneous pins engage the bony structure as well, thereby promoting overall stability of the device.

A surgical headframe for maintaining a stereotactic system reference frame relative to a patient's head. The headframe includes a frame body, first and second arms, a plurality of contact pads, and a strap. The first and second arms extend from opposing sides of the frame body, respectively. The plurality of contact pads are coupled to the frame body and are each adapted to engage a patient's head. The strap is selectively connectible to the first and second arms. In this regard, the strap is adapted for wrapping about a back of a patient's head. The surgical headframe is capable of precisely positioning and fixating the reference frame to the patient's head daring these stereotactic procedures.
