| 摘要 |
An orthopedic impacting tool comprises a motor, a linear motion converter, an air chamber, a compression piston, an impacting element, an anvil element, and a broach adapter. The compression piston may cause the impacting element to apply controlled force on a broach adapter to create a precise opening for subsequently disposing a prosthesis in a patient. The tool allows forward or backward impacting for expanding the size or volume of the opening or for facilitating removal of the broach and tool from the opening. A force adjustment control of the tool allows a user to increase or decrease the impact force. A light source and hand grips improve ease of operation of the tool. |

1. An orthopedic impacting tool for striking an object, the tool comprising
a motor, a linear motion converter, a compression piston operatively coupled to said linear motion converter, said piston having a first end and a second end, an air chamber, said air chamber comprising a forward portion and a rear portion,
wherein said forward portion is proximate to said first end of said compression piston and said rear portion is proximate to said second end of said compression piston, an impacting element, a control unit, an anvil element with a front face and a rear face, said anvil element adapted to accept a portion of a broach adapter, a broach adapter capable of holding a broach, chisel, reamer, or other surgical implement, said broach adapter operatively coupled to said anvil element and being proximate to said first face of the anvil element and distal to said second face of said anvil element, and a hand grip, wherein said control unit directs said motor to move said linear motion converter and causing said compression piston to move and compress air within said front portion of said air chamber or compress air within a second portion of said air chamber, and wherein said impacting element moves to impact said front face of said anvil element, upon application of compressed an from the first portion of said air chamber and wherein said impacting element moves to impact said rear face of said element upon application of compressed in from the second portion of said air chamber such that the impacting element is capable of imparting a force upon the broach adapter in at least one direction. |
