## Abstract

Systems and devices may include a motor operatively coupled to a driveshaft configured to be driven in a first direction in a first mode for impaction and a second direction in a second mode for retraction. Systems and devices may include an anvil configured to be operatively coupled to an implement. Systems and devices may include an impaction cam operatively coupled to the driveshaft, wherein: the impaction cam, when in an impaction position, is configured to strike the anvil when driven by the driveshaft in the first direction to drive the anvil in an impaction direction. Systems and devices may include a retractor configured to be driven by the retraction cam in the second direction, wherein the retractor is configured to strike the anvil to drive the anvil in a retraction direction.

## Claims

### Claim 1

An orthopedic impactor system, comprising:
a motor operatively coupled to a driveshaft;
an anvil configured to be operatively coupled to an implement handle; and
an impaction cam operatively coupled to the driveshaft, wherein:
when in an impaction position, the impaction cam is configured to strike the anvil when driven by the driveshaft in a first direction to drive the anvil in an impaction direction,
when retarded, the impaction cam is configured to be forced out of contact with the anvil in a first axial direction along a longitudinal axis of the driveshaft, and
the impaction cam is configured to be forced back into the impaction position in a second axial direction when the impaction cam rotates past the anvil, wherein the impaction cam is operatively coupled to the driveshaft via a plurality of ball bearings interfacing with a plurality of respective spherical grooves defined by the driveshaft and a plurality of respective sockets defined by the impaction cam.

### Claim 2 (depends on 1)

The system of claim 1, further comprising a spring configured to force the impaction cam in a second axial direction along the longitudinal axis of the driveshaft into contact with the anvil.

### Claim 3 (depends on 1)

The system of claim 1, further comprising a speed control input configured to adjust a frequency of impacts.

### Claim 4 (depends on 3)

The system of claim 3, further comprising a mode selector input configured to place the impactor in a first mode or second mode.

### Claim 5 (depends on 1)

The system of claim 1, further comprising a battery electrically coupled to the motor.

### Claim 6 (depends on 1)

The system of claim 1, wherein the anvil is coupled to the implement using a connection mechanism.

### Claim 7 (depends on 6)

The system of claim 6, wherein the connection mechanism includes a plurality of lockable positions with respect to a longitudinal axis of the anvil.

### Claim 8 (depends on 1)

The system of claim 1, further comprising a vibratory assembly coupled to the implement handle.

### Claim 9 (depends on 1)

The system of claim 1, wherein the system is configured to produce high-frequency, low force impacts.

### Claim 10

An orthopedic impactor system, comprising:
a motor operatively coupled to a driveshaft;
an anvil configured to be operatively coupled to an implement handle; and
an impaction cam operatively coupled to the driveshaft, wherein:
the impaction cam is configured to strike the anvil when driven by the driveshaft to drive the anvil in an impaction direction,
the impaction cam is configured to be retarded when a minimum force is sustained by the anvil, and
retarding the impaction cam is configured to force the impaction cam out of contact with the anvil in a first axial direction along a longitudinal axis of the driveshaft,
wherein the impaction cam is operatively coupled to the driveshaft via a plurality of ball bearings interfacing with a plurality of respective spherical grooves defined by the driveshaft and a plurality of respective sockets defined by the impaction cam.

### Claim 11 (depends on 10)

The system of claim 10, further comprising a spring configured to force the impaction cam in a second axial direction along the longitudinal axis of the driveshaft into contact with the anvil.

### Claim 12 (depends on 10)

The system of claim 10, wherein the impaction cam is operatively coupled to the driveshaft via a plurality of ball bearings interfacing with a plurality of respective spherical grooves defined by the driveshaft and a plurality of respective sockets defined by the impaction cam.

### Claim 13 (depends on 10)

The system of claim 10, further comprising a speed control input configured to place the impactor in a first mode or second mode.

### Claim 14 (depends on 10)

The system of claim 10, further comprising a battery electrically coupled to the motor.

### Claim 15 (depends on 10)

The system of claim 10, wherein the anvil is coupled to the implement using a connection mechanism.

### Claim 16 (depends on 15)

The system of claim 15, wherein the connection mechanism includes a plurality of lockable positions with respect to a longitudinal axis of the anvil.

### Claim 17 (depends on 10)

The system of claim 10, further comprising a vibratory assembly coupled to the implement handle.

### Claim 18 (depends on 10)

The system of claim 10, wherein the system is configured to produce high-frequency, low force impacts.
