  • Patent number: 11872000
    Abstract: The disclosed technology relates to robotic surgical systems for improving surgical procedures. In certain embodiments, the disclosed technology relates to robotic surgical systems for use in osteotomy procedures in which bone is cut to shorten, lengthen, or change alignment of a bone structure. The osteotome, an instrument for removing parts of the vertebra, is guided by the surgical instrument guide which is held by the robot. In certain embodiments, the robot moves only in the “locked” plane (one of the two which create the wedge—i.e., the portion of the bone resected during the osteotomy). In certain embodiments, the robot shall prevent the osteotome (or other surgical instrument) from getting too deep/beyond the tip of the wedge. In certain embodiments, the robotic surgical system is integrated with neuromonitoring to prevent damage to the nervous system.

  • Patent number: 11717137
    Abstract: A medical system and an operating method of a medical system are disclosed. The medical system can operate an endoscope to perform an operation task with respect to a site of interest of an organ of concern in response to input from an operator. The medical system includes a controller that can record a model of the organ of concern generated during preoperative planning, and record the names of a plurality of sites in the organ of concern, and corresponding regions or points in the model with respect to a first coordinate system. The controller receives the name of the site of interest, and the operation task; associates the first coordinate system of the model with a second coordinate system of a display space displayed by a display image; and operates the endoscope with respect to the site of interest on the basis of the operation task.

  • Patent number: 11642138
    Abstract: Disclosed herein is a patella clamp configured to grip a patient's patella. The patella clamp includes a clamping assembly, a ratchet arm assembly, and a handle assembly. The clamping assembly includes first and second patella grip portions mounted in opposing relationship. In use, actuation of the handle assembly moves the second patella grip portion towards the first patella grip portion to clamp the patient's patella. The handle assembly is configured to be moveably adjustable (e.g., rotatable) relative to the clamping assembly. For example, each of the first and second patella grip portions are coupled to mating features mounted on the ratchet arm assembly. Decoupling of the mating features allows the first and second patella grip portions to rotate about the longitudinal axis of the ratchet arm assembly. Thus arranged, the patella clamp is configured to enable the surgeon to reposition the handle assembly to provide increased visibility, etc.

  • Patent number: 11622776
    Abstract: The present jig for guiding placement of femoral component of the implant in a knee replacement surgery (J) is a pre-assembled Jig (J) which ensures precision fit femoral implant for knee replacement based on difference of cuts in millimeters instead of the usual angle measurement in degrees. It avoids intrusion of the intramedullary canal substantially decreasing the risks of embolism. It enables the surgeon to use precise values of depth of cuts obtained from a system for obtaining optimum fit implant as described in patent application number 3896/MUM2015. This enables the surgeon to control precisely the placement of the implant in terms of flexion or extension, varus or valgus, internal or external rotation It also enables precise placement of the fourin-one cutting block simultaneously with the distal femur cut; ensuring precise placement of knee femoral component of the knee implant. This reduces efforts and time taken during the surgery.
