A handheld surgical instrument comprising an energy storage element, wherein the energy storage element is a spring coupled to the impacting mechanism, an impacting mechanism has a tip configured to impact a bone, wherein the tip includes a tapered point, a power transmission mechanism is configured to transmit energy from the energy storage element to the impacting mechanism, wherein the power transmission mechanism includes a semi-flexible metal wire guided by a hollow shaft, wherein the hollow shaft includes a distal end, the semi-flexible metal wire is includes a bend toward the distal end, a trigger mechanism is configured to release energy from the energy storage element, wherein the bend includes an angle between 14 degrees and 46 degrees, wherein the trigger mechanism includes a manual lever which, when actuated, simultaneously retracts the tip and charges the energy storage element.

A device for spinal implant removal includes a driver tool and a capture tool. The driver tool includes an elongated cylindrical body with a through-opening and two distal end protrusions. The capture tool includes an elongated shaft configured to fit and extend through the cylindrical body through-opening of the driver tool and has a distal end opening with inner threads. The spinal implant includes a cylindrical body and first and second sets of wings that are configured to engage first and second spinous processes of two vertebrae, respectively. The cylindrical body houses a threaded post that actuates the deployment of the first and second sets of wings. The two distal end protrusions of the driver tool are configured to engage a circular collar formed around the threaded post on a top surface of the cylindrical body. The driver tool with the engaged circular collar are rotated counter clockwise to screw the threaded post out of the cylindrical body and thereby to release the first and second sets of wings. The elongated shaft of the capture tool is configured to be rotated counter clockwise to capture outer threads of the threaded post with the inner threads of the distal end.

An orthopaedic surgical instrument may include an elongated body with an implant end and an impactor end. A latch lever may be pivotally coupled to the elongated body. The latch lever may be moveable between an open position and a latched position in which the latch lever is retained within the body. An acetabular shell component may be rigidly attached to the implant end of the elongated body. An automated surgical impactor may be attached to the impactor end.
