An orthopaedic surgical instrument system includes a sensor adapter and multiple surgical instruments. The sensor adapter includes a housing with a force sensor positioned within the housing and a sensor contact configured to transfer force to the force sensor extending from the housing. Each surgical instrument includes a sensor connector configured to receive the sensor adapter at a predetermined location relative to the surgical instrument. Each sensor adapter further includes a registering feature to engage an anatomical feature of a patient or another surgical instrument. The surgical instruments may include a shim that may be attached to a gap assessment tool or a tibial insert trial. Methods associated with the surgical instrument system are also disclosed.

Methods and systems for identifying and determining the size and orientation of a reamed portion of a patient's bone are disclosed. A tracking array and / or a point probe can be inserted into an adapter device. The adapter device includes a plurality of openings with various connection means therein such that when a tracking array is inserted into the adapter, a secure and stable connection is created. A reamer, a handle, or similar tool can then be inserted into the opposite side of the adapter during which a secure and stable connection is established between the adapter and the tool. Thus, a more accurate representation of a patient's anatomy can be obtained through the use of a computer-assisted surgical system.

A system of patient-matched and surgeon-specific single use surgical instruments designed for five different applications for knee replacement surgeries; primary total knee replacement, custom-made total knee replacement, revision total knee replacement, hinged total knee replacement and partial knee replacement. The system has patient-matched & surgeon-specific instruments are designed & prepared for each case based on patient's need and surgeon's demand. The system contains patient-matched set of blocks and guides, “On-Demand” surgeon-specific Instruments sets, conventional instruments sets, surgical planning software, 3D printing Software, 3D printers and sterilization unit. All the system components are manufactured by using 3D printing technologies.

The embodiment of the invention is suitable for the technical field of computer-aided medical treatment, and provides an orthopedic surgery robot system and an orthopedic surgery intra-operative planning method, the system is connected with a pressure sensor, and the system comprises a data acquisition module used for acquiring bending and stretching data of legs of a patient; the data processing module is used for receiving the pressure data, collected by the pressure sensor, of the knee joint of the patient and generating intraoperative planning information based on the flexion and extension data and the pressure data; and the display feedback module is used for displaying the intra-operative planning information and guiding a surgeon to perform a total knee replacement operation on the patient. By adopting the system, the dynamic, automatic and accurate adjustment of the intraoperative operation planning can be realized, the dependence on the personal experience of doctors is reduced, and the soft tissue balance effect and the operation success rate are improved.

This invention relates to a patient positioner and, more specifically, to an articulated armature configured to position a leg and knee at a precise angle, as needed in unicompartmental knee arthroplasty surgery. The positioner is adapted to connect to either side rail of a support table, without changing orientation, via drop pins disposed in a socket clamp. The socket clamp may couple to a ball coupled to a first arm and elbow joint, which in turn may couple to a second arm and wrist joint, which in turn may couple to a pad assembly adapted to hold the patient's thigh, thereby positioning the lower leg to dangle over the side or end of an operating table. The positioner is adapted for ease of disassembly, sterilization, and reassembly. The invention may be exchanged for a total knee replacement positioner without moving the patient or breaking the sterile field.

The invention relates to functionally graded polymeric knee implants for enhanced fixation, wear resistance and mechanical properties and manufacture thereof. The present invention includes polymer-based femoral and / or tibial component implants for total knee replacement / replacement procedures for providing improved wear resistance, enhanced physiological response at the bone / implant interface, and reduced stress shielding. The implant may be made via additive manufacturing. The articular surface of the implant may be implemented in the absence of any additive or in a form containing an additive for improving the tribological response. Furthermore, the instruments disclosed herein contain an interface surface (i.e., a bone / implant interface) in contact with natural bone, which may be present in its pure form, containing a bioactive additive. The implant has a porous topography on the bone / implant interface to improve biological response and improve fixation. Wherein the depth and topography of the additive is controlled via the techniques disclosed herein.

The invention provides a cold region orthopedics department digital intelligence diagnosis and treatment intelligent operation planning system comprising a total knee joint replacement planning module used for planning according to an acquired knee joint medical image and cold region specificity data; the total hip replacement planning module is used for planning according to the acquired hip joint medical image and cold region specificity data; the unicondylar joint replacement planning module is used for planning according to the obtained knee joint medical image and cold region specificity data; the acetabulum periphery osteotomy planning module is used for planning according to the obtained hip joint medical image and cold region specificity data; the sports medical planning module is used for planning according to the acquired joint medical image and cold region specificity data; the spine planning module is used for planning according to the spine medical image and the cold region specificity data; and the trauma planning module is used for performing trauma operation planning according to the trauma part medical image and the cold region specificity data.

The embodiment of the application is suitable for the technical field of computer-aided medical treatment, and provides an orthopedic surgery robot system and an intraoperative planning method for orthopedic surgery. The system is connected with a pressure sensor and comprises a data acquisition module, a data processing module and a display feedback module. The data acquisition module is used for acquiring flexion and extension data of a patient's leg. The data processing module is used for receiving pressure data of the patient's knee joint collected by the pressure sensor, and generating intraoperative planning information based on the flexion and extension data and the pressure data. The display feedback module is used for displaying the intraoperative planning information and guiding a surgeon to perform total knee arthroplasty on the patient. By using the above system, dynamic, automatic and accurate adjustment of intraoperative surgery planning can be realized, the dependence on the personal experience of the surgeon is reduced, and the effect of soft tissue balance and the success rate of surgery are improved.

A polymeric based femoral and / or tibial component implant can be be used in total knee replacement / arthroplasty procedures serving to provide increased wear resistance, enhanced physiological response at the bone / implant interface, and decreased stress-shielding. The implant can be made via additive manufacturing. The articulating surface of the implant may be implemented in without any additive or in a form containing an additive for improved tribological response. Further, the a device contains an interfacial surface which is in contact with the native bone (i.e., bone / implant interface) which may exist in its pure form, containing a bioactive additive. The implant has a porous morphology on the bone / implant interface for improved biological response and improved fixation. The depth of the additives and the topographical morphology therein are controlled via techniques disclosed herein.
