Robotic arthroplasty system

解决的技术问题

The present invention relates to a method of securing either hard or soft body tissue. A robotic mechanism or manual effort may be used to position a fastener relative to the body tissue. The fastener may be a suture, staple, screw, or other known device.It is contemplated that the robotic mechanism may advantageously be utilized to position surgical implants other than fasteners in a patient's body. For example, the robotic mechanism may be utilized to position a prosthesis in a patient's body. If desired, the robotic mechanism may be utilized to position a screw type fastener at a specific location in a patient's body. The robotic mechanism may be used to position a scaffold containing viable tissue compOnents relative to body tissue.

技术方案

Embodiments include a robotic mechanism that may be utilized to position prosthetic implants in a patient's body. During joint replacement surgery and other surgical procedures, prosthetic implants may be placed in a patient's body. The robotic mechanism may be utilized to control movement of a cutting tool during resection of bOne in a patient's body. The robotic mechanism includes a programmable computer which is connected with the force transmitting member by a motor. A force measurement assembly is connected with the force transmitting member and the computer. The output from the force measurement assembly is indicative of a resistance encountered by the force transmitting member. A position sensor is connected with the force transmitting member and the computer. The position sensor has an output indicative of the position of the force transmitting member.

Neurosurgical assistance robot

解决的技术问题

One of the important aspects of a surgical robot of the type of the invention resides in the stability required by the accuracy of the surgical gesture, which stability should in this case be made to rhyme with a dimensional variability/modularity. The aim of optimal adaptation to the position of the head of the patient should not be met to the detriment of the mechanical rigidity guaranteeing this stability. Thus, a rigid reference structure has been set up, provided with an element (the plate), which the surgical robotic arm, on the One hand, and the head-supporting arm, on the other hand, are directly made integral with, their distribution with respect to this plate further reinforcing the mechanical rigidity and the stability of the assembly.

技术方案

The disclosed subject matter relates to a neurosurgical assistance robot including a movable box the chassis of which is provided with a rigid support arm for connection to a headrest supporting the head of a patient lying on an operating table. Accore invention disclosed subject matter, the support arm is movable with respect to the chassis between a position retracted in the volume of the box and a plurality of extended positions, and a mechanism for locking the arm in any iled being provided for.

Robotic-assisted device for positioning a surgical instrument relative to the body of a patient

解决的技术问题

The aim of the invention is to cope with the drawbacks of the state of the art by providing a device for positioning a surgical instrument relative to the body of a patient using at least a first robotic arm supporting at least One surgical instrument and a second tracker arm, which is also a robotic arm. This second robotic arm is aimed at detecting in real time and accurately the movements of said body and to communicate them to said first arm, so that it compensates its position accordingly. In particular, said second arm permits to detect the internal and external movements of the anatomic area to be treated.

技术方案

The robotic device for positioning a surgical instrument relative to the body of a patient includes a first robotic arm with a device for rigidly connecting to at least One surgical instrument, a device for anatomical realignment of the first arm by realigning an image that is of an area of the anatomy of the patient, and a device for compensating the movements of the first arm on the basis of detected movements. One version of the device includes at least One second robotic arm having sensors for detecting inner movements of the anatomical area, and a device for controlling the positioning of the first arm relative to sensed inner movements and to the outer movements induced in the second arm.
