when your switching back and forth with your fingers, afther sewing then the tying of the sutures, grab the forceps. you can save some time from throwing them a way then going back to get them. Holding the forceps with the ring and little fingers, with the distal interphalangeal joints in extension frees the middle finger to maneuver through a greater range of motion as opposed to the forceps being grasped by the fingers. the muscle belly looks similar to the flexor digitorum profundus muscle, ring and little fingers, you can find a way to flex your middle finger by flexing the distal joints of your two fingers. when you have in place your little finger and your distal joints of the ring make sure when you grab the forceps that you have the flexor digitorum profundus muslce relaxed, making possible full, free extension of the middle finger for other manipulation. When left-handed little finger and ring finger manipulation is needed during a portion of one-handed tying, temporarily shift the palmed forceps to a pinch in the web between the thumb and index finger.
The flexor digitorum profundus sends tendons towards the distal phalanges of the ring, long and tiny digits, so flexion of the distal interphalangeal joints of two fingers also flexes the third. Your bad habits feel more comfortable than your newly tried, superior ways.
You can change from a holding posture to a "use" posture. This can be acheived by going up & down on the forceps, when they're grasped for the first time at the proper mark with index & thumb. The correct grab is not difficult with the palm facing up, as gravity causes the forceps to sit against the palm, making extreme metacarpal-phalangeal joint rotation of the index & thumb finger.
Grabing at the correct spot is made easier by turning the palm down, you do this so gravity can relocate your forceps away from the palm; Your thumb and index can now grab the correct place without massive flexing of the metacarpal-phalangeal joints.
Efficient and Smooth transfer of the forceps from the "use" to the "hold" stance and back again, this will then become a smooth process.
