End effectors, systems, and methods for impacting prosthetics guided by surgical robots

Abstract

Provided is an end effector for impacting a prosthesis at a surgical site along a trajectory maintained by a surgical robot. The end effector comprises an impactor assembly and a guide. The impactor assembly has a head to receive impact force, an interface to releasably attach to the prosthesis, a shaft extending along an impactor axis between the head and the interface, and an impactor engagementsurface disposed between the head and the interface. The guide is adapted to attach to the surgical robot and comprises a channel extending along a guide axis and defining an opening arranged to receive a portion of the shaft of the impactor assembly, a guide engagement surface shaped to abut the impactor engagement surface, and a limiter to maintain abutment of the impactor engagement surface with the guide engagement surface to facilitate coaxial alignment of the axes with the trajectory maintained by the surgical robot.

Description

[0001] Cross references to related applications [0002] This patent application claims the priority and all rights of the United States Provisional Patent Application No. 62 / 622,303 filed on January 26, 2018, the disclosure of which is incorporated herein by reference in its entirety. Background technique [0003] Surgical robots are often used to help medical professionals perform various routine surgical operations. To this end, surgeons can use surgical robots to guide, position, move, actuate, or otherwise manipulate various tools, components, prostheses, etc. during surgery. [0004] It should be understood that surgical robots can be used to assist surgeons in performing many different types of surgical operations, and are generally used in operations involving the correction, resection or replacement of degenerative joints to help improve the patient's mobility and relieve pain. For example, in hip replacement surgery, the surgeon replaces certain parts of the patient's hip ...

Problems solved by technology

[0006] Depending on the configuration of the prosthetic components, impact tool and surgical robot, ensuring proper implantation of the prosthetic cup can be complicated by lack of visibility and limited access to the surgical site

Additionally, maintaining a set trajectory can be difficult for certain methods and surgical techniques, often resulting in incorrect alignment of the prosthetic cup or other prosthetic components due to incorrect alignment and / or application of impact force. alignment
