Systems and methods for assisting users with accurate tool identification. A tool includes a tool feature, and a navigation system includes a localizer to detect a position of the tool feature. A memory stores identification data associated with a plurality of tools. Controller(s) is/are coupled to the navigation system, the memory and the display. The controller(s) receive, from the localizer, the detected position of the tool feature and compare the detected position of the tool feature with the identification data stored in the memory to determine an identity of the tool. The controller(s) present, on a display, the identity of the tool and an identity of at least one other tool.

Surgical systems and methods for identifying tools guided by surgical robots

Femoral implant component

A method includes providing a distraction device, and providing, separate from the distraction device, a disposable force sensor pod configured to be removably coupled to the distraction device. The method also includes communicating, by the disposable force sensor pod, information relating to distraction of a joint by the distraction device to a computing system.

Distraction device with disposable force sensor pod

A joint distraction lever, comprising a lever body comprising a handle portion and a working portion, a distal tip coupled to the working portion, and a fulcrum extending from a bottom surface of the working portion and spaced apart from the distal tip such that the fulcrum is positioned between the distal tip and the handle portion, where the joint distraction lever is configured to determine a distraction force based on deformation of the joint distraction lever.

Force measuring joint distraction lever

A joint distraction lever includes a lever body having a handle portion coupled to a working portion, a fulcrum extending from a bottom surface of the working portion of the lever body, a distal tip, which is raised above a top surface of the working portion of the lever body, a force measurement device used to measure a distraction force applied at the distal tip during a distraction procedure for a joint during which a torque is applied at the handle portion of the lever body, and a force value output used to indicate the distraction force applied at the distal tip.

A system for intra-operatively registering a pelvis comprising an acetabulum with a computer model of the pelvis in a coordinate system. The system may include: a) a surgical navigation system including a tracking device; and b) at least one computing device in communication with the surgical navigation system. The at least one computing device: i) receiving first data points from first intra-operatively collected points on an articular surface of the acetabulum, the first data points collected with the tracking device; ii) receiving a second data point from a second intra-operatively collected point on the pelvis, the second data point collected with the tracking device, the second data point corresponding in location to a second virtual data point on the computer model; and iii) determining an intra-operative center of rotation of the femur relative to the pelvis from the first data points.

Systems and methods for intra-operative pelvic registration

A registration system including a bone pin guide and a bone pin clamp. The bone pin guide may include a guide body, a first guide including a first guide through-hole having a first longitudinal axis, and a second guide including a second guide through-hole having a second longitudinal axis. The bone pin guide may guide first and second bone pins into a bone via the first and second guides. The bone pin clamp may include a clamp body, first, second, and third clamp through-holes extending through the clamp body, a plurality of registration indents defined on the clamp body, and a clamping mechanism including at least one adjustable fastener. The bone pin clamp may receive the first and second bone pins in the first and third clamp through-holes and guide a third bone pin into the bone via the second clamp through-hole.

Registration tools, systems, and methods

A surgical system includes a disposable force sensor pod that includes a load cell and a mounting feature. The surgical system also includes a computing system configured to be placed in electronic communication with the disposable force sensor pod and receive a force measurement from the disposable force sensor pod. The disposable force sensor pod is configured to be removeably coupled to a distraction device using the mounting feature.

A method for assessing a joint includes inserting a joint distraction lever into a space between a first bone and a second bone of the joint, distracting the joint with the joint distraction lever, determining, using a measurement device of the joint distraction lever, a distraction force applied by the joint distraction lever as the joint distraction lever is used to distract the joint, determining whether the distraction force matches a predetermined amount of the distraction force, and in response to determining that the distraction force matches the predetermined amount of the distraction force, capturing first poses of the first bone and the second bone.

A surgical system for assisting a user in performing a surgical procedure at a surgical site, comprising a tool having a checkpoint, a pointer having a tip, and a localizer to determine a position of the pointer within a field of view. A memory comprises identification data associated with a plurality of tools. A controller is configured to prompt the user to position the tip of at the checkpoint, to receive position data from the localizer associated with the pointer within the field of view, to compare position data associated with the pointer against the identification data of the memory to determine an identity of the tool, and to present the user with the identity of the tool.

A joint distraction lever for use during a distraction procedure is disclosed. The joint distraction lever includes a lever body having a handle portion coupled to a working portion, a fulcrum extending from a bottom surface of the working portion of the lever body, a distal tip, wherein the distal tip is raised above a top surface of the working portion of the lever body, a force measurement device configured to measure a distraction force applied at the distal tip during a distraction procedure for a joint during which a torque is applied at the handle portion of the lever body, and a force value output configured to indicate the distraction force applied at the distal tip.

Electronic force measuring joint distraction lever and method of use thereof

A joint distraction lever for measuring a distraction force is disclosed. The joint distraction lever includes a lever body having a handle portion and a working portion. The lever body has a fulcrum extending from a bottom surface of the working portion of the lever body and a distal tip, wherein the distal tip is raised above a top surface of the working portion of the lever body. The joint distraction lever is configured to measure a distraction force applied at the distal tip during a distraction procedure when a torque is applied by an external force applied on the handle portion of the lever body. The joint distraction lever further includes an indicator configured to provide feedback related to the distraction force applied at the distal tip, as measured by the joint distraction lever.
