Description

Adapter for surgical impact tool Cross Reference to Related Applications The present application claims priority from U.S. provisional patent application No. 63/519,450, entitled "Adapters For Surgical Impacting Tools," filed on 8/14/2023, which is hereby incorporated by reference in its entirety. Technical Field The present disclosure relates generally to adapters for surgical impact tools. Background In the field of orthopaedics, prosthetic devices such as artificial joints are typically implanted or placed in the bone cavity of a patient. The cavity is typically formed during a surgical procedure, and then the prosthetic device is placed or implanted by, for example, a physician or other medical professional removing and/or compacting the existing bone to form the cavity. Prosthetic devices (which may also be referred to as prostheses) typically include a shaft or other projection that is inserted into a lumen. To create a cavity, a physician or other medical professional may use a drill, osteotome, or other surgical instrument that conforms to the shape of the shaft of the prosthetic device. Generally, a surgical instrument is pushed into the implantation area to form a cavity. One technique for pushing a surgical instrument includes a physician or other medical professional manually hammering a surgical impact tool to push the surgical instrument into an implantation area. Another technique for creating a prosthetic cavity relies on a computer-controlled robotic arm to create the cavity, rather than using manual power provided by a physician or other medical professional. Another technique for creating a prosthetic cavity is to pneumatically drive the surgical instrument, for example, by compressed air. Another technique for creating a prosthetic chamber relies on a linear compressor to compress air on a single stroke basis and then, after sufficient pressure is created, through a valve and release the air onto the impactor to propel the surgical instrument. A drill, osteotome, or other surgical instrument may be removably coupled to the surgical impact tool, for example, to allow surgical instruments of different sizes and/or shapes to be used with the surgical impact tool in different surgical procedures, to help accommodate the needs of a particular patient, to allow replacement of worn, damaged, or otherwise undesirable surgical instruments for future use without having to replace the remainder of the surgical impact tool, and/or to accommodate personal preference of the surgeon for surgical instruments. However, the various techniques for pushing the surgical instrument to create the prosthetic cavity (such as the four techniques discussed above) may loosen the removable coupling of the surgical instrument to the surgical impact tool due to the force required to push the surgical instrument. Such slackening may result in the surgical instrument accidentally disengaging from the surgical impact tool during a surgical procedure, may result in the surgical instrument rocking or otherwise moving in an unintended direction, and thus cause patient injury and/or adversely affect cavity formation, and/or may impede cavity formation by not allowing the surgical instrument to be received and pushed with a fully intended force. Accordingly, there remains a need for improved surgical impact tools. Disclosure of Invention Generally, an adapter for a surgical impact tool and a method of using an adapter for a surgical impact tool are provided. In one aspect, a surgical device is provided that, in one embodiment, includes a first adapter and a second adapter. The first adapter is configured to extend distally from a surgical impact tool handpiece configured to drive an impact to bone. The first adapter is configured to be releasably attached to a surgical impact tool handpiece, and the first adapter includes a first mating feature configured to be releasably coupled to a first mating element of a first surgical instrument configured to impact bone. The second adapter is configured to extend distally from the surgical impact tool handpiece. Only one of the first adapter and the second adapter is configured to extend distally from the surgical impact tool handpiece at a time. The second adapter is configured to be releasably attached to a surgical impact tool handpiece, the second adapter including a second mating feature configured to be releasably coupled to a second mating element of a second surgical instrument configured to impact bone, and the second mating feature is different from the first mating feature. The surgical system may be varied in a number of ways. For example, the second mating feature may have a different geometry than the first mating feature. As another example, the first mating feature may be configured to cooperate with the first mating element to prevent rotation of the first surgical instrument relative to the first adapter with the first surgical instrument releasably attached to the f
