A plate for attaching to an anatomic structure with fasteners. The plate has a body with a top surface and a bottom surface opposite the top surface. The body defines one or more openings to receive a respective one of the one or more fasteners. The bottom surface is concave to define a space to accommodate a portion of the anatomic structure. A bone pad surface extends from the bottom surface. A spike extends away from the bone pad surface. An extension arm can be coupled to the plate and the extension arm can support a tracking head to implement a surgical tracking assembly.

Bone plate for attaching to an anatomic structure

A kinematic mounting key engageable with a kinematic mounting receiver is provided. The kinematic mounting key comprises a base kinematic element, a first protrusion, and a second protrusion. Each of the first protrusion and the second protrusion defines a clearance channel and comprises a kinematic element. The clearance channels and the kinematic elements are configured so that the kinematic mounting key is engageable with the kinematic mounting receiver in a first arrangement at six points of contact and in a second arrangement at six points of contact that are at least partially different from the six points of contact of the first arrangement.

Bidirectional kinematic mount

A plate for attaching to an anatomic structure with fasteners. A body defines openings for receiving the fasteners, and includes a bottom surface that is concave. The plate includes bone pad surface, and a spike extends away from the bone pad surface. The bone pad surface is oriented at an angle relative to the bottom surface to prevent further penetration of the spike into the anatomic structure beyond a predetermined depth. The bone pad surface may be oriented at an obtuse angle relative to the bottom surface. The bone pad surfaces may be planar or concave, or contoured to a corresponding profile of the anatomic structure. The spikes may be pyramidal or conical. At least one side of the spike may be integral and continuous with the bottom surface. The side may have a radius of curvature equal to that of the bottom surface.

A surgical assembly for kinematically coupling two surgical components is provided. The surgical assembly includes a first surgical component having a receiver, which defines a cavity and has a plurality of constraint surfaces accessible in the cavity. The surgical assembly further includes second surgical component having a key, which has a triplicity of kinematic elements to repeatably position the key in the receiver. The surgical assembly further includes a preloading mechanism having a load member arranged to secure the key in the receiver such that the kinematic elements contact the receiver at the plurality of constraint surfaces such that the key is kinematically constrained to the receiver by being constrained by six points of contact with the receiver.

Surgical assembly with kinematic connector

A tracking device for a surgical navigational system. A tracking head includes tracking elements configured to communicate tracking information to the surgical navigation system. An extension arm is configured to be coupled to the tracking head, and a bone plate is configured to be coupled to the extension arm. The bone plate is further configured to be coupled to anatomic structure and includes openings each configured to receive a fastener. A central opening may be provided to receive an additional fastener for coupling the extension arm to the bone plate. A recess within the top surface may receive the base plate of the extension arm. Spikes of the bone plate are configured to penetrate the anatomic structure and, in conjunction with the fasteners, prevent movement of the tracking device. The bottom surface is concave between the spikes to define a space configured to accommodate portions of the anatomic structure.

A kinematic connector assembly for kinematically coupling two objects is provided. The kinematic connector assembly comprises a receiver defining a cavity and having a plurality of constraint surfaces accessible in the cavity. The kinematic connector assembly further comprises a key having a triplicity of kinematic elements to repeatably position the key in the receiver. The kinematic connector assembly further comprises a preloading mechanism having a load member movable between a clamped position and an unclamped position to secure the key in the receiver, so that the kinematic elements contact the receiver at the plurality of constraint surfaces such that the key is kinematically constrained to the receiver by being constrained by six points of contact with the receiver.

Navigation tracker with kinematic connector assembly

A plate for attaching to an anatomic structure. The plate comprises a top surface opposite a bottom surface. An opening through the top and bottom surfaces is configured to receive a fastener to attach the plate to the anatomic structure. The plate comprises spikes configured to penetrate the anatomic structure. With the fastener, the spikes prevent rotational movement of the body relative to the anatomic structure. The bottom surface is concave between the spikes and defines a space configured to accommodate portions of the anatomic structure. Bone pad surfaces are configured to prevent further penetration of the spikes into the anatomic structure when in contact the same. A tracking device for a surgical navigational system can comprise a tracking head coupled to the plate with a mounting arm. The plate, when attached to the anatomic structure, prevents movement of the tracking device relative to the anatomic structure.

Bone plate and tracking device using a bone plate for attaching to a patient's anatomy

Disclosed herein is a clamp attachable to a support rail of a hospital bed, for example. The clamp includes a body, first and second arms coupled to the body, wherein the first and second arms are moveable towards and away from one another. The clamp further includes at least one seat clamp member pivotably coupled to at least one of the first and second arms. The clamp is attached to the support rail when the at least one seat clamp member contacts the support rail and the first and second arms are in a clamped position.
