A fixed angle instrument includes an elongate guide extending from a proximal end to a distal end, the guide having a proximal portion extending along a longitudinal axis and a distal portion extending transverse to the longitudinal axis. The instrument further includes a shaft disposed within the guide extending through the proximal portion of the guide along the longitudinal axis. The instrument further includes an intermediate element coupled to the shaft, the intermediate element having at least one bulbous link. The instrument further includes a distal element coupled to a distal end of the intermediate element.

The present disclosure provides a cutting tool for surgical procedures. More specifically, the present cutting tool is suitable for bi-directional cutting and removal of soft and hard tissues for surgical procedures. The cutting tool includes a substantially rigid shaft having a shaped end portion. The shaped end portion includes a plurality of shaped talons; each talon including a body bent to retain tissue, and each talon including a cutter end. The cutter end includes both acute and obtuse cutting surface relief angles for diverse cutting action with respect to hard and soft tissues.

A surgical tool that has a pair of transmissions coupled to one another to effect driving of a cutting tool in both bidirectional intermittent rotational manners and in opposite directions of continuous rotation. The transmissions are driven by a motor coupled to one of the transmissions which is coupled to the second transmission.

An improved flexible endoscopic instrument to precisely and efficiently obtains samples of flat polyps and multiple polyps from a patient by debriding one or more polyps and retrieving the debrided polyps without having to alternate between using a separate cutting tool and a separate sample retrieving tool and may be used with an endoscope. In one aspect, the cutting tool is coupled to a flexible torque coil or torque rope that is configured to transfer rotational energy from a powered actuator through the length of the endoscope onto the cutting tool.

Disclosed is an instrument assembly usable in a procedure. The instrument includes a connection for a working portion and to a tool handle. The assembly includes a method and system for interconnection and/or identification of the working portion and the handle. The instrument may also include various trackable features to allow for a navigated procedure.

Disclosed herein is a medical device. The medical device includes a blade tube section, a solenoid, and a mechanical arrangement. The blade tube section includes an outer blade tube, an inner blade tube, and a cutting window at a distal end of the blade tube section. The solenoid is offset from a central axis of the blade tube section. The mechanical arrangement is between the inner blade tube and the solenoid.

A device for removal of a tissue specimen from a patient includes a housing and a morcellator segment. The device includes a spindle capable of traveling through a longitudinal bore of the housing, and a specimen bag at a distal portion of the housing. In use, the specimen bag is extended from the distal portion of the housing and the spindle passes through the housing and specimen bag, exterior of the specimen bag, thereby forming an opening in the specimen bag. The spindle passes through a tissue specimen, at which point the spindle is retracted to bring the tissue specimen through the specimen bag, and into the longitudinal bore of the housing. The tissue specimen passes through the morcellator segment of the device, whereby the tissue specimen is broken into smaller pieces for ease of removal from the patient's body and further examination.

An instrument sleeve is provided for use with a surgical rotary instrument having a tube extending to a distal tube end, and a cutting accessory having a head and a shank extending from the head adapted to be rotatably supported by the tube of the rotary instrument. The instrument sleeve comprises a sleeve body extending between proximal and distal sleeve portions, a first lumen for receiving at least a portion of the tube of the rotary instrument, and a shield extension coupled to the sleeve body. The shield extension extends between proximal and distal shield portions the proximal shield portion engaged with the distal sleeve portion and adapted to minimize tissue wrap about the cutting accessory shank.

Methods for accessing a disc space of a patient as a part of an interbody fusion, as well as the tools employed therewith. An exemplary method may include inserting a leading end of a tool into the patient's back at a location on the posterior surface that is laterally offset from a patient's spinous process and disc. The tool's initial entry into the patient may be from a posterior approach. As the tool is advanced along its designated path, it begins to deviate from the posterior approach towards a lateral approach. When the leading end reaches the disc, it may access the disc from a lateral or substantially lateral location. The tool may be used to access the disc location, to remove disc material, to deliver a cutting tool for removing the disc material, and other steps associated with the spinal interbody fusion procedure.

A minimally invasive tissue incision system for creating joint capsulotomies and releasing/incising various tissues, tendons, and fibrous band structures is described. The system contains a penetrating needle which is retractable so as to expose a cutting element, and which may be used as a penetrating needle to pierce the skin and other soft tissue structures. The cutting element provided within the penetrating needle may be used to incise subsequent tissue structures after the initial penetration. The system facilitates such procedures by providing the cutting element with the confines of the needle which provides safe introduction of the cutting element directly to the site via the needle.
