Besides a variety of knife blade configurations, there are other cutting surgical instruments, kinda like chisels, osteotomes, forceps, surgical scissors, meniscus knives, periosteal elevators, urterine curette and bone, strippers, dermatomes and saws for special purposes. Sort of like the scapel, The proper way by using these medical tools the avoids it slipping by that correct incision.

With bone-cutting chisels & osteotomes the most controlled cut is the one induced by a hammer or mallet. The slightest controlled cut with osteotomes and chisels is made by pushing. It always helps when you hold these surgical instruments in a safe palm gripping action To avoid them from changing direction from the desired course of from going deeper than determined by the magnitude of the mallet stroke.

The most stable cut and safe cut is in soft tissue, such as endometrium, by finger and hand motion, holding the surgical instrument in a pencil grip. Better controlled than pushed strokes with a curette are back-and-forth rotating motions or pulling strokes, which will get rid of the possible scerario of it going deeper in the wound.

Bone power saws with rotational oscillation are built so that the teeth move back and forth with short stokes the delicate tissue may move near the teeth rather than be cut. However, there is no absolute preference of the saw for bone. If you allow the blade in to long up against the soft tissue or if you press the saw to firmly, it will make a cut. A hazard becomes a man-cut when you cant see its surface is hidden under-view. However, if you cut the material using a saw with an up-and-down motion, you can remove that danger. By pushing lightly on the blade perpendicular to the line, you can feel the blade go through the depp cortex & right away get rid of pressure. Then advance the blade in a shallower depth and again press to go through the next increment of the deep table.

Next is the stryker saw which has a minimum radius, so to obtain maximal cutting depth do not surround the gearbox with the right hand. To have stability and direction attitude, clutch the motor in your left hand. Then press on the gearbox with the heel of your right hand to achieve the desired pressure on the blade. You will be able to sense with your right hand the instant the blade pierces the deep cortex.

Bone saws which oscillate up & down instead of oscillating in a rotating direction, have a guide at the far end of the blade that protects the underlying tissue. Its important to spread the bone and the soft tissue underneath, to provide a path for the guide & to prevent entrapment of the deep structures.
