A discectomy tool comprising: a) a cannula having an outer surface having a longitudinal bore therein, a proximal end and a distal end; b) a steering wire disposed in the longitudinal bore; c) a flexible, hollow transmission shaft disposed in the cannula, the shaft having a throughbore, a proximal end portion, a distal end portion and an outer surface having a thread extending therefrom; d) an irrigation source fluidly connected to the throughbore; e) a cutting tip attached to the distal end portion of the transmission shaft.

A milling device for surgery, in particular prosthetic surgery, comprising a handling body containing a transmission unit terminating in attachment portions and with which there is rotatably associated a cutter, said device comprising hooking means of the releasable type associated with a distal attachment portion of said attachment portions.

Tool assemblies and methods are disclosed, such as for robotic-assisted surgery with a robot. The tool assembly includes a working tool (44) sized to be coaxially movable within the dilator (60). A locking mechanism (70) releasably couples the working tool (44) and the dilator (60) to one another such that, in a locked configuration, the robot supports the tool assembly. An actuator (86) is configured to receive an input to move the locking mechanism to an unlocked configuration and permit axial movement of the working tool within the dilator. The dilator (60) may include at least one spike (104) disposed within the grooves (128) to penetrate bone. The dilator (60) may include an inner sleeve and outer sleeve coaxially movable relative to one another to move the tool assembly from an initial configuration to a deployed configuration in which the spikes are exposed beyond the sleeve(s). Methods of preparing a pedicle of the spine with the tool assembly with robotic assistance are also disclosed.

A system for coupling a tendon to a bone may include a tendon coupling device engageable with a tendon, a fastener to secure the tendon coupling device to the tendon, a bone coupling device, and a flexible element. The flexible element may include a first portion and a second portion. The first portion of the flexible element may be couplable with the fastener to securably attach the flexible element to the tendon. The bone coupling device may include a bone-facing surface engageable with a surface of the bone proximate a bone tunnel formed through the bone, and a hole formed through the bone coupling device. The second portion of the flexible element may be receivable through the bone tunnel and the hole formed through the bone coupling device to engage an opposing surface of the bone coupling device and securably couple the tendon to the bone.

A soft tissue and bone repair system and corresponding method are provided which are particularly useful for labral repairs in the human shoulder. The system comprises at least two guide cannulae capable of being introduced into an anatomical structure of a human body at different entry points for repair of a tear in soft tissue. A pulling line can be passed within the anatomical structure between the guide cannulae. A guide device may be attached to the pulling line and inserted into one of the guide cannula. The guide device is capable of delivering a drilling device into the anatomical structure. The pulling line is capable of being pulled to move an end of the guide device from a one location to another within the anatomical structure to position the drilling device on a desired drilling path to access the tear in soft tissue.

A drill guide assembly for drilling a tunnel having a fixed, non-zero radius of curvature, where the drill guide assembly includes a housing and a sleeve, or cutting tube, configured to reciprocate within the distal portion where the sleeve, or cutting tube, is configured to receive a bone cutting instrument.

Various surgical tools having a movable handle mechanism including a positioning handle are disclosed. The movable handle mechanism may be configured to move forward and backward in a longitudinal direction along the housing and rotate clockwise and counterclockwise around the housing. In various embodiments, the housing may include a plurality of channels and each channel may have at least one detent. The movable handle mechanism may be configured to securely couple to the housing via one channel of the plurality of channels and one detent of the plurality of detents. At least one surgical tool may include a drill having an angled tip portion and a sleeve configured to protect adjacent structures from lateral edges of the drill bit when the drill bit is rotating. Another surgical tool may include a screwdriver having an elastic retaining clip configured to progressively release a bone screw therein at an extraction force.

Disclosed herein is a surgical tool for debulking hard tissue. The surgical tool includes: (i) an elongated hollow member including a distally located bent section; (ii) a cable extending within the hollow member, along a predetermined length thereof; (iii) a headpiece positioned at, or distally to, the bent section; (iv) a rotation actuator coupled to the cable proximal end and configured to rotate the cable about a longitudinal axis thereof; and (v) a motion converter coupled to a distal end of the cable and to the headpiece, at least part of the motion converter is positioned in, and/or distally, to the bent section, the motion converter being configured to transform rotational motion of the cable into an axial, reciprocating motion of the headpiece. The headpiece is configured to break up hard tissue by hammering thereof, when effecting axial, reciprocating motion, while simultaneously minimizing damage to soft tissue if struck.

Tools for cutting bone, specifically cutting a hemispherical cavity in bone. Preferably, tools including an adaptor device configured to provide independent control of the cutting orientation.

A front end attachment for a powered surgical tool. The front end attachment includes a nose. The nose defines a bore for receiving a shaft of a cutting accessory that is connectable to a motor of the powered surgical tool. The nose also defines a groove separate from the bore. The groove is formed in an outer surface of the nose and extends longitudinally along the nose. An irrigation fitting includes a tube that is seated in the groove of the nose. The irrigation fitting is adapted to receive an irrigating fluid. A heat shrink tubing is disposed over the outer surface of the nose to extend over and enclose the groove. The heat shrink tubing secures the irrigation fitting to the nose.
