Powered surgical drill with integral depth gauge that includes a probe that slides over the drill bit

A drill for driving a drill bit into a solid object such as bone. The drill includes a rotor with a bore that transmits rotational movement to the drill bit. The drill bit extends through the rotor bore. A probe extends forward from the drill to measure bore depth. The probe is moveably mounted to the drill so as to extend into the rotor bore. As the drill and drill bit advance forward the probe remains static. As a result of the advancement of the drill the rotor extends over the proximal end of the probe.

Expandable reaming device

An expanding reamer for reaming or cutting a concave surface, for example, for reaming an acetabulum in preparation for implanting a prosthetic component, such as an acetabular cup or socket, during a hip arthroplasty. The reamer includes a rotating shaft cooperating with a surgical drill or other power source at one end and rotating a reamer head at the other end, and a system adapted to expand one or more blades on the reamer head. In a preferred version, the reamer head comprises a plurality of generally circular, preferably substantially flat and parallel blades, the outer blades of which are radially expandable as segments of a cutting sphere to enlarge the effective diameter of the reamer head. A transverse blade may guide expansion of the blades to move upwards as well as outward to maintain a nearly perfect cutting sphere across a range of diameters. Upon rotation of the reamer head, the blades form a portion of an effective cutting sphere that is preferably greater-than-180-degrees in order to allow greater flexibility in placement of the shaft of the reamer relative to the surface being reamed, for example, relative to the center of axis of the acetabulum.

Surgical drill guide

The present invention is directed to a surgical drill guide. The drill guide may include a first drill guide body having a distal end for placement substantially adjacent a bone, a second drill guide body slidable with respect to the first drill guide body and having a proximal end for contacting a portion of a drill bit, a handle associated with at least one of the first drill guide body and the second drill guide body, and a detent mechanism for releasably retaining the position of the first drill guide body with respect to the second drill guide body in predefined increments. Additionally or alternatively, the drill guide may include a locking member movable between a first position where it substantially prevents sliding of the second drill guide body with respect to the first drill guide body, and a second position where it permits sliding of the second drill guide body with respect to the first drill guide body. The locking member may be resiliently biased to the first position. Other features for improving the drill guide are disclosed and claimed as well.

Surgical Drill For Providing Holes At An Angle

A surgical drill for providing holes at an angle for use in repair and replacement of the ACL is disclosed, generally comprising a drill guide having a head that is angularly adjustable with respect to a body, a flexible guide pin and a flexible drill. The adjustable head of the drill guide allows a surgeon to drill a hole in the femur at an angle to a tunnel provided in the tibia. Because the surgeon can access the femur via the hole in the tibia, the surgical drill of the present invention obviates the need for a second hole in the tissue and also makes placement of femur hole more precise for securement of the ligament or tendon graft within the hole.

Expandable surgical reaming tool

InactiveUS20070016211A1Effective reaming/cuttingIncrease the effective diameterSurgeryRotational axisSurgical drill
An expanding reamer for reaming or cutting a concave surface, for example, for reaming an acetabulum in preparation for implanting a prosthetic component during a hip arthroplasty. A rotating shaft cooperates with a surgical drill or other power source at one end and rotates a reamer head at the other end, and an actuation system expands one or more blades on the reamer head. The reamer head comprises one or more cutting blades, which act as segments of a cutting sphere, wherein the blades are expandable in directions non-parallel to the plane of the respective blades in order to enlarge the cutting sphere. Upon rotation of the reamer head, the blade(s) form a portion of an effective cutting sphere that is preferably greater-than-180-degrees; this allows greater flexibility in placement of the shaft of the reamer relative to the surface being reamed, for example, relative to the center of axis of the acetabulum. In one embodiment, two parallel blades move out away from each other and away from the rotational axis of the device, staying parallel to each other to become, in effect, more distanced, but still parallel, segments of a larger cutting sphere. In another embodiment, two blades start generally parallel to each other and to the rotational axis of the device, but pivot out from each other in directions generally perpendicular to their respective blade planes, again becoming more distanced, but not parallel, segments of a larger cutting sphere.

Variable depth drill with self-centering sleeve

A surgical drill assembly is provided that includes an elongate shaft having a proximal end adapted to mate to a driver mechanism, and a distal end having a bone preparation element formed thereon. An elongate, hollow sleeve is coupled to, but slidably disposed around at least a portion of the elongate shaft. The hollow sleeve includes a stepped region that is positioned between proximal and distal portions such that the distal portion has an outer diameter that is less than an outer diameter of the stepped region to allow the distal portion to be disposed within a lumen in a drill guide, and the stepped region to abut the drill guide. In use, the elongate, hollow sleeve is effective to longitudinally align the elongate shaft therein during a surgical procedure. The elongate shaft can also optionally include a stop member that is effective to limit penetration depth of the bone preparation element with respect to the hollow sleeve.

Freely separable surgical drill guide and plate

Instrumentation for osteofixation including a locking bone plate and a surgical drill guide. The plate has a plurality of fastener holes with inner walls of a preselected hole diameter. The drill guide has a guide member, for guiding a drill bit, and a hollow collet disposed substantially coaxially with the guide member. A radially expandable forward end of the collet comprises a radially expandable neck and an outwardly projecting rim disposed forward of the neck. This rim defines a contracted outer rim diameter that is smaller than the hole diameter in a contracted collet position, and an expanded outer rim diameter that is larger than the hole diameter in an expanded position. Thus, the rim is freely extractable through the plate hole in the contracted position, but is unreceivable through the plate hole in the expanded position. The collet neck is configured and dimensioned to press outwardly against an inner wall of the plate hole when the neck is expanded.
