Techniques For Patient-Specific Milling Path Generation
Surgical systems, computer-implemented methods, and software programs for generating a milling path for a bone. The implementations involve obtaining a virtual model of the bone, a resection volume defined relative to the virtual model of the bone, and a reference guide defined with respect to the resection volume. Section planes are successively arranged along the reference guide, and each section plane intersects the reference guide and intersects the resection volume. A section path is generated within each section plane and is defined relative to the resection volume. Transition segments are generated to connect section paths of section planes. The milling path is then generated by combining the section paths and the transition segments.
DEVICES AND TECHNIQUES FOR HIP REVISION SURGERY
Piezoelectric osteotomy devices and corresponding systems and methods for removing an acetabular cup or shell from a patient's acetabulum are disclosed. In one embodiment, the piezoelectric osteotomy device includes a piezoelectric element to actuate a cutting tip on an armature. In some such embodiments, the cutting tip may be extended and/or retracted to facilitate cutting of bone around an acetabular cup. The armature may include a fluid output port located proximate the cutting tip to mitigate heat generated by the cutting tip. In one embodiment, the piezoelectric osteotomy device is arranged and configured to provide constant current adjustment.
Systems and methods to adjust bone cut positioning based on bone hardness
Systems and methods for adjusting bone cut positioning are disclosed that can aid in optimizing implant size selection and positioning relative to bone during, e.g., orthopedic surgical procedures such as knee arthroplasty, hip arthroplasty, etc. In one embodiment, such a surgical method can include performing a first bone cut of a first bone using an at least partially robot-assisted surgical instrument, detecting one or more parameters related to bone hardness, selecting a bone hardness index based on the one or more detected parameters, and adjusting a position of a second bone cut of the first bone based on the selected bone hardness index to optimize implant fit relative to bone. Detecting the one or more parameters related to bone hardness can be performed in a number of manners, including by monitoring energy required to perform the first bone cut.
Robotic surgery system with tool edge sensors for edge computing
Methods, apparatuses, and systems for edge computing in surgical robotics is provided. The system comprises a surgical robot communicatively coupled to a 3rd party operating room equipment system over a cloud network. The surgical robot includes an operating room hardware configured to perform a surgical procedure on a patient. A memory is communicatively coupled to operating room hardware and user interface, and the memory comprises an equipment database and a threshold database to store parameters related to the operating room hardware. A processor, coupled to the operating room hardware via the network interface, is configured to establish a connection between the surgical robot and the 3rd party operating room equipment system, and monitor events being performed by the operating room and then store the monitored data within the threshold database. The threshold database stores trigger values for each piece of equipment for taking actions, based on data collected by sensors.
INSERT ASSEMBLY WITH RADIOFREQUENCY IDENTIFIER FOR MEDICAL DEVICE
An insert assembly, insertable in a handpiece of a medical device, has an insert having an insert metal tang, a ferromagnetic layer in contact with the insert metal tang, a dielectric layer in contact with the ferromagnetic layer, an insert antenna in contact with the dielectric layer, having an insert antenna metal element and configured to receive and transmit electromagnetic fields, and an identification chip operatively connected to the insert antenna and configured to transmit information about the insert assembly. The ferromagnetic layer reduces or cancels attenuation and/or distortion phenomena of an electromagnetic field caused by parasitic effects due to interaction of a transmitted or received electromagnetic field with metal parts of the insert metal tang, liquids present in the insert, and the insert antenna metal element. The ferromagnetic layer dielectric layer and insert antenna form a transceiver device putting the identification chip in communication with a handpiece antenna.
CONTROL METHOD OF BONE GRINDING, TERMINAL DEVICE AND STORAGE MEDIUM
A control method of bone grinding includes: receiving a current position of a grinding drill bit from a positioning apparatus in real time; determining whether the current position reaches a region boundary of a region to be ground in a grinding state; and controlling the grinding drill bit to stop operating when the current position reaches the region boundary.
Method and System for Determining a Safety Criterion during an Autonomous Manipulation of a Surgical Tool by a Robotic System to Treat an Anatomical Structure
The invention relates to a method for determining a safety criterion during an autonomous manipulation of a surgical tool (13) by a robotic system (1) to treat an anatomical structure (B) according to a planned trajectory (T.sub.3D) in a 3D image (I.sub.3D), said 3D image being registered with a patient tracker (30), and the robotic system (1) being servo-controlled on the movements of the patient tracker (30), the method comprising: a. acquiring at least one 2D X-ray image (I2D) containing the anatomical structure and the surgical tool by an X-ray imaging system (2), and for each at least one 2D X-ray acquisition: i. synchronously localizing the surgical tool and
registering the 2D X-ray image (I.sub.2D) with the 3D image (I.sub.3D) in a region of interest around the anatomical structure, iii. generating a projection onto the 2D X-ray image (I.sub.2D) of a model of the surgical tool in its position relative to the 3D image computed in step (i) (‘projected localized position’), iv. determining a real position of the surgical tool on the 2D X-ray image (I.sub.2D) (‘real position’), b. determining a safety criterion from a similarity information between each real position and each projected localized position of the surgical tool on the at least one 2D X-ray image.
Surgical Drilling System For Determining Bone Breakthrough
A surgical drill bit for bone drilling and for determining a characteristic of a drilling medium from a characteristic of fluid flow. The surgical drill bit includes a shank portion for coupling to a drill chuck. The shank portion defines a proximal opening. The surgical drill bit also includes a drilling portion for drilling through bone. A distal cutting region (62) of the drilling portion includes a rake surface (66), a clearance surface (68), and a flank surface (70). The flank surface (70) defines a distal opening (72) and is configured to abut the bone such that the distal opening is occluded by the bone while the rake surface is cutting into the bone. The shank and drilling portions collectively define an inner channel in fluid communication with the proximal and distal openings. The distal opening is occluded by the bone during drilling to establish fluid pressure within the inner channel.
MEDICAL APPARATUS AND MEDICAL STORAGE MEDIUM
A medical apparatus includes a treatment mechanism, a slave actuator, an operation control unit, and a parameter acquisition unit. The treatment mechanism is used for treating a patient. The slave actuator causes the treatment mechanism to perform the treatment. The operation control unit calculates the control parameters related to the force tactile sensation, based on the information about the position that is detected along with the treatment and controls the operation of the slave actuator for causing the treatment mechanism to perform the treatment, based on the control parameters related to the force tactile sensation. The parameter acquisition unit acquires the control parameters related to the force tactile sensation.
Mixed-reality surgical system with physical markers for registration of virtual models
An example method includes obtaining, a virtual model of a portion of an anatomy of a patient obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; identifying, based on data obtained by one or more sensors, positions of one or more physical markers positioned relative to the anatomy of the patient; and registering, based on the identified positions, the virtual model of the portion of the anatomy with a corresponding observed portion of the anatomy.
