Abstract

Claims (53)

1 . A modular system comprising:

a limited-use battery-operated orthopedic hand tool having modular internal components; said modular internal components comprising:

a motor providing a rotational output;

an internal drive mechanism comprising: (1) a first motor output drive shaft; (2) a motor shaft coupling; (3) a second output shaft; and (4) at least one drive shaft bearing;

a first ring surrounding the at least one drive shaft bearing;

a second ring encircling the motor shaft coupling;

a third ring encircling the motor;

a handle grip;

a trigger mechanism to control the motor;

a control processor; and

a battery;

wherein the first ring includes at least one of polychloroprene (neoprene), ethylene vinal acetate (EVA), polyvinyl chloride (PVC), or combinations thereof; the second ring includes at least one of neoprene, EVA, PVC, or combinations thereof; and the third ring includes at least one of neoprene, EVA, PVC, or combinations thereof.

2 . The system of claim 1 , further comprising a drive mechanism shroud encasing the internal drive mechanism.

3 . The system of claim 2 , wherein the drive mechanism shroud internally comprises one or more elastomeric dampers having a durometer between Shore A 60-100 or between Shore D 0-60.

4 . The system of claim 2 , wherein the drive mechanism shroud externally comprises one or more elastomeric dampers having a durometer between Shore A 60-100 or between Shore D 0-60.

5 . The system of claim 1 , further comprising:

a second drive shaft configured at a different orientation to the first motor output drive shaft;

at least one bearing on the second drive shaft; and

an attachment receiver coupled to the second drive shaft for modular attachments used for performing surgical procedures;

wherein the second drive shaft and the at least one bearing on the second drive shaft further comprise elastomeric damping features.

6 . The system of claim 5 , wherein the internal drive mechanism comprises one or more elastomeric dampers having a durometer between Shore A 60-100 or between Shore D 0-60 about or around the first motor output drive shaft, the second output shaft, the second drive shaft, or combinations thereof.

7 . The system of claim 5 , wherein the attachment receiver is configured to receive cutting attachments.

8 . The system of claim 5 , further comprising a drive mechanism shroud encasing the internal drive mechanism, wherein the motor, the internal drive mechanism, the drive mechanism shroud, the trigger mechanism and the attachment receiver are configurable as modular components.

9 . The system of claim 1 , wherein the battery-operated orthopedic hand tool is:

a reciprocating saw; or

an oscillating saw.

10 . The system of claim 1 , wherein the second output shaft is an offset shaft.

11 . An oscillating saw system comprising:

a first housing;

a motor within the first housing;

a second housing;

a linkage;

a first shaft coupling the motor to the linkage, the first shaft including a central first axis that intersects the motor;

a second shaft coupled to the linkage, the second shaft having a central second axis that is orthogonal to the first axis;

a first bearing, wherein the second axis passes through the first bearing;

an elastomeric first ring surrounding the first bearing and directly contacting the first bearing;

an elastomeric second ring directly contacting the second housing and is inside the first housing but outside the second housing;

an elastomeric third ring encircling the motor;

wherein a first plane is orthogonal to the first axis and intersects the first and second housings;

wherein the elastomeric second ring is coplanar with the first plane;

wherein the elastomeric first ring includes at least one of polychloroprene (neoprene), ethylene vinal acetate (EVA), polyvinyl chloride (PVC), or combinations thereof;

wherein the elastomeric second ring includes at least one of neoprene, EVA, PVC, or combinations thereof;

wherein the elastomeric third ring includes at least one of neoprene, EVA, PVC, or combinations thereof;

wherein the oscillating saw is sterile.

12 . The oscillating saw system of claim 11 , wherein the first and second housings are separable from one another.

13 . The oscillating saw system of claim 11 , wherein the linkage is forked and includes opposing first and second tines.

14 . The oscillating saw system of claim 13 comprising an offset shaft that couples the first shaft to the linkage.

15 . The oscillating saw system of claim 14 comprising a sterile disposable packaging system, wherein the first and second housings are coupled to each other and are included in the sterile disposable packaging system.

16 . The oscillating saw system of claim 11 , wherein the motor is configurable to drive the second shaft between 7,000-14,000 oscillations per minute (OPM).

17 . The oscillating saw system of claim 11 comprising a saw blade module configured to directly connect to a saw blade, wherein the central second axis intersects the saw blade module.

18 . The oscillating saw system of claim 11 comprising a saw blade module configured to directly connect to a saw blade, wherein:

an additional axis is parallel to the central second axis;

the additional axis intersects the saw blade module.
