Abstract
A rongeur-type surgical device incorporating a powered rotary cutting tool having a protective distal foot plate portion which protects against injuring non-target tissue enabling the rapid and safe removal of specifically-targeted bone, cartilage, and soft tissue.
Claims20
A powered rongeur type surgical instrument comprising:
- a handle having a movable portion forming an actuator and an elongate support portion having a distal end;
- a receiver carriage slidably coupled to said handle;
- a foot plate coupled to said distal end of said elongate support portion, said foot plate defining a cutting element receiving channel;
- a rotary shaft assembly having a motor interface for receiving a removably mounted motor in said receiver carriage at a proximal end of said rotary shaft assembly and a cutting element interface portion at a distal end of said rotary shaft assembly for receiving a rotary cutting element having a selected size and shape, said receiver carriage moving along a defined rectilinear path along the support portion in response to actuation of the handle for selectively positioning said rotary shaft assembly relative to said foot plate;
- and
- wherein the foot plate receiving channel is sized and shaped to substantially correspond to the selected size and shape of the rotary cutting element and is positioned to receive said rotary cutting element and cover at least a portion of a periphery of the rotary cutting element when said handle is actuated.

A powered rongeur type surgical instrument comprising:
- a body having a fixed handle portion and an elongate receiver carriage support portion having a distal end;
- a receiver carriage slidably coupled to said body, said receiver carriage including a motor interface for receiving and retaining a removable motor and a rotary shaft having a cutting tool interface for removeably connecting a selected rotary cutting element, said rotary shaft being aligned with said elongate receiver carriage support portion of said body;
- a movable handle pivotally coupled to said body and engaging said receiver carriage such that pivotal actuation of said movable handle towards said fixed handle portion from a first position to a second position results in linear displacement of said receiver carriage along said body towards said distal end of said carriage support portion;
- a foot plate coupled to the distal end of said elongate receiver carriage support portion of said body and positioned in alignment with said cutting tool interface, said foot plate defining a receiving channel which is sized and shaped to substantially conform to a size and shape of the selected rotary cutting element, said foot plate receiving said rotary cutting element and covering at least a portion of a periphery of said cutting element when said movable handle is in said second position.
