Abstract
Various surgical impactors are disclosed. The surgical impactor may include a housing, a rod that extends at least partially inside the housing, a hammer head attached to the rod, and a hammer housing that receives the hammer head. Actuation of the rod can cause the hammer head to move proximally and/or distally inside, and to impact, the hammer housing. The force of the impact can be conveyed to a surgical implant, instrument, etc.
Claims20
A surgical impactor comprising:
- a housing comprising a proximal end, a distal end, a cavity extending from the proximal end to the distal end, and a linear actuator;
- a rod comprising a proximal end and a distal end, the distal end comprising a first threading, wherein the rod is removably disposed inside the cavity of the housing;
- a hammer head on the distal end of the rod, the hammer head comprising a proximal end with a second threading;
- a hammer housing comprising a proximal end with a first opening, a distal end with a second opening, and a cavity disposed between the first and second openings;
- and
- an adapter comprising a proximal end and a distal end, wherein the proximal end of the adapter is attached to the distal end of the hammer housing;
- wherein the hammer head is inside the cavity of the hammer housing and is configured to move relative to the hammer housing;
- wherein the linear actuator is configured to move the rod, which causes the hammer head to move axially inside the hammer housing and to impact an inner surface of the hammer housing;
- and
- wherein the first threading and the second threading are configured to engage to connect the rod and the hammer head.

A surgical handpiece comprising:
- a grip,
- a trigger positioned along the grip,
- a barrel connected to the grip, the barrel comprising a cavity;
- and
- a surgical impactor positioned inside the cavity of the barrel, the surgical impactor comprising:
- a housing comprising a through-lumen;
- a rod positioned at least partially in the through-lumen;
- a hammer head on an end of the rod;
- a hammer housing configured to receive the hammer head, the hammer housing comprising a proximal end having an edge, wherein the edge is configured to block the hammer head from escaping the hammer housing in a proximal direction;
- a linear actuator configured to move the rod relative to the housing and to dampen impact force from being transferred from the rod to the housing;
- and
- an electronic controller configured to control operation of the linear actuator at least partly in response to actuation of the trigger.
