A saw blade clamping device is configured to clamp at least two types of saw blades and includes a clamping seat and an operating member. The clamping seat has a connecting portion and a loading portion with a loading slot. The operating member has an operating portion with assembling and loading ends. The operating portion is assembled around the loading portion with the assembling end, and the loading end has a loading port. The operating member is rotatable relative to the loading portion. An inner wall of the operating member has a curved driving surface. An abutting element, disposed between the operating member and the clamping seat, has an abutting end, which can extend into the loading slot, and a driving end, which abuts against the driving surface. The abutting end is driven by the driving surface during rotation of the operating member to move into the loading slot.

A reciprocating tool easily supplies a lubricant, such as grease (lubricating oil), to a mechanism for reciprocating a slider, and prevents a lack of lubricant. A reciprocating saw as a reciprocating tool includes a motor, a reciprocating conversion mechanism that converts rotation of the motor to reciprocation, a slider connected to the reciprocating conversion mechanism and being reciprocable, and a slider guide that supports the slider in a reciprocable manner and includes a lubricant-passage member in contact with the slider to allow passage of at least part of a lubricant through the lubricant-passage member, and a lubricant reservoir located adjacent to the lubricant-passage member to store the lubricant.

In one embodiment, a reciprocating tool includes a reciprocating plunger, the plunger including an inner wall defining a chamber portion within the plunger, a motor operably connected to the plunger, and a bushing located at least partially within the chamber and contacting the inner wall.

Surgical instruments, systems, and methods for performing an osteotomy are disclosed herein. A surgical system includes a body with a distal end, a proximal end, a first surface, and a second surface. The surgical system can include cutting blades positioned on the first surface and/or the second surface. The surgical system can include columns of cutting blades positioned on the first surface and/or the second surface. The surgical system can include rows of cutting blades positioned on the first surface and/or the second surface.
