Systems and methods for arranging objects in an operating room in preparation for a surgical procedure. The objects are arranged based on surgical procedure information provided to a guidance station. The surgical procedure information dictates the desired placement of the objects. Placement of the objects is then guided according to their desired placement using one or more tracking elements.

A patient-specific guide tool for guiding an instrument toward a bone for implantation of a prosthetic device is disclosed. The guide tool includes a body portion having a guide element, and a patient-specific portion having at least one patient-specific mating feature that is configured to engage a soft tissue at or near the bone. A method of manufacturing a guide tool for guiding an instrument toward a bone is also disclosed.

Embodiments of a system and method for surgical tracking and control are generally described herein. A system may include a robotic arm configured to allow interactive movement and controlled autonomous movement of an end effector, a cut guide mounted to the end effector of the robotic arm, the cut guide configured to guide a surgical instrument within a plane, a tracking system to determine a position and an orientation of the cut guide, and a control system to permit or prevent interactive movement or autonomous movement of the end effector.

The invention relates to a surgical system for cutting an anatomical structure (F, T) of a patient according to at least one target plane defined in a coordinate system of the anatomical structure, comprising: (i) a robotic device (100) comprising: —a cutting tool, —an actuation unit (4) having a serial architecture comprising from three to five motorized degrees of freedom, at least two of said motorized degrees of freedom being rotational degrees of freedom about respective rotation axes that are substantially orthogonal to each other, configured for adjusting a position and orientation of the cutting tool relative to each target plane, —a planar mechanism connecting the last segment of the actuation unit to the cutting tool; (ii) a passive articulated lockable holding arm (5) supporting the actuation unit (4); (iii) a tracking unit (200) configured to determine in real time the pose of the cutting plane with respect to the coordinate system of the anatomical structure, (iv) a control unit (300) configured to determine the pose of the cutting plane with respect to the target plane and to control the actuation unit so as to bring the cutting plane into alignment with the target plane.

A method for correcting position of an osteotomy guide tool and an orthopedic operation system are disclosed. A trackable element mounted on the osteotomy guide tool or on the robotic arm tracks the position of the osteotomy guide tool and generates position information of the trackable element. According to the current position and the desired position of the trackable element, a robotic arm drives the osteotomy guide tool and the trackable element to move, until the trackable element is moved to the desired position. This method does not need to consider the absolute position accuracy of the robotic arm, and does not rely on the experience of the surgeon. The tool has several guiding features, which can provide guides for osteotomy operations, so that the same osteotomy guide tool can perform multiple operations of osteotomy and punching, thus greatly reducing the operation time and improving the operation efficiency.

A resection guide locator includes a bone engagement portion with surfaces that are complementary to the surface topographies of a bone to be resected during surgery. A housing includes a socket defined by a resilient annular wall that is sized and arranged so to accept a resection guide by press-fit to thereby position and hold the resection guide within the socket. The resection guide is maintained in a predetermined, preferred position while the surfaces are releasably locked in position on the bone. A method is disclosed for forming and using the resection guide locator.

A joint balancing insert with an actuated mechanism is for balancing a joint during a joint surgery is disclosed. The joint balancing insert includes a first plate, a second plate and an actuator there between. The second plate includes an integrated mounting portion for mounting a cutting block used to guide surgical cuts of the joint during the joint surgery. Various configurations of the integrated mounting portion may be implemented in the insert to provide for mounting various types of cutting blocks, such as cutting blocks for tibial cuts, femoral cuts, and distal femoral cuts.

The disclosure herein relates to various surgical methods for implanting a prosthesis in a patient. In particular, in some embodiments, a surgical method for preparing a knee of a patient to implant a customized knee prosthesis comprising: identifying epiphysary axis (2) of the patient tibia (1) by connecting the center of the tibial plateau with the center of the growth plate remnant on a preoperative planning; and performing a tibial cut (3) perpendicular to the epiphysary axis (2) of the tibia (1).

A system for making a proximal resection of tibia having localized anatomical surface features prior to resection, comprising: a resection guide locator including a body, the body including opposing medial and lateral wings extending outwardly from the body, the body defining a recess being a socket defined by an annular wall, the annular wall including an upper wall, a lower wall, a resection guide having a body defining a resection slot, at least a portion of the resection guide body sized and configured to be received within the recess defined by the resection guide locator.

Provided is a method for designing a patient-specific surgical device for performing knee surgery, which includes determining a first alignment axis and/or a second alignment axis from a knee joint in extension and/or flexion respectively and subsequently designing said surgical device based on the first and/or second alignment axes. Also provided is a method of manufacturing a patient-specific surgical device designed by the aforementioned method. A patient-specific surgical device designed and/or manufactured by the above methods and a method of performing knee surgery with said patient-specific surgical device is further provided.
