When alternately needing to grasp with fingers and forceps, as when sewing then tying sutures, when palming the forceps. Can save time lost from repeatedly get rid of and retrieving them. hold on to the forceps with the pinky and ring fingers, with your middle finger free to move around more freely with the distal joints than when the forceps are grasped by flexed phalanges. The flexor digitorum profundus muscle has a familiar muscle belly to the middle, little fingers & ring, so flexion of the distal joints of two fingers to hold the forceps also flexes the middle finger. when you have in place your little finger & your distal joints of the ring when grabing the forceps leaves the flexor digitorum profundus muscle relaxed, this will free up your middle finger for better movement. you will need the use of your left hand pinky and ring finger for one-handed tying, try to swift your palmed forceps to use a pinching-like motion with your index finger & thumb.
The flexor digitorum profundus sends out tendons to the distal fingers of the long, ring and small digits, so when you flex the distal interphalangeal joints of your 2 fingers this will also flex the third. Bad habits are always more comfortable than newly tried, better ways.
Changing from "hold" to a "use" stance can be done with individual motion climbing up & down the forceps, if they're first grasped at the proper spot with thumb and index. The correct grab is difficult with the palm up, as gravity causes the forceps to lie against the palm, requiring ultimate metacarpal-phalangeal joint flexion of the thumb and index finger.
Grasping at the proper part is completed easier by making the palm down, so that gravity moves the forceps away from the palm; the index finger & thumb can then grasp the desired place without extreme flexion of their metacarpal-phalangeal joints.
Careful and cautous transfer for your forceps to the "use" to the "hold" position & back again becomes automatic, secure and comfortable with practice.
