The automatic tissue forceps which I have devised, will be found to be an instrument of great utility in operative work and also one of precision. It is made of English steel, and consists of two blades which terminate in teeth. Midway between the extremities of the blades is the catch, which locks and unlocks automatically, synchronously with the grasp or release of tissues.
The instrument is operated with the thumb and index finger of the left hand with the same ease as in the use of the ordinary tissue forceps. Pressure sufficient simply to pick up the tissues is all the force required to lock the blades. This is at a minimum, as the blades possess great elasticity and consequently accommodate themselves to the "bite" of tissue, whether large or small.
To disengage the blades and release the grip, simply give them another gentle squeeze, when the catch unlocks.
