“…The quiet hand technique is performed by the thumb and I, II, III fingertips. Each muscle contraction adds tiredness and predisposes to tremor [8-10]. Any kind of fixed support can be placed close to the operative site for hand support.…”

Microvascular anastomosis procedure has become an essential practice for the management of most neurovascular diseases. Increasing use of neurosurgical techniques necessitates intensive laboratory training in microsurgery.Umbilical artery is used for quantifiable representation to set up microvascular anastomosis model for the beginners. These arteries are found to be between 4 and 5 mm in diameter. Chicken wings are set up as second anastomosis model. Five to six centimeter long brachial artery extracted from a chicken is measured approximately 1-2 mm in diameter. These arteries are practiced for end-to-end, end-to-side, or side-to-side anastomosis under the microscope.Umbilical cord and chicken wing model hold several advantages. These essentials are inexpensive, convenient to manage, and easy to obtain for educational purposes. They neither need detailed facilities for maintenance like in animal model nor any anesthetic prerequisite. Moreover, the diameter and structure of the material are identical to those of human cortical vessels.Low-cost laboratory training during residency is more relevant in source restraint areas. It has several added benefits in refining the procedural dexterity on anastomosing smaller size vessel identical to a cortical vessel of middle cerebral artery and distal branches of the superficial temporal artery.

“…The bridge is necessary because the closest fi xed points on the skull or any part of body including the well known armrest devices could be placed so far too far to balance and drive the microinstruments to the operating point only by the fi ngertip. The fi ngertip support technique was introduced at different microneurosurgical approaches 1,2,3,4 ( Figure 3) and gives signifi cant reduction of postoperative complications 3,4 . Randomized trial of tremor reduction by robot hand technique has not been performed so far.…”

ObjectiveThe physiological tremor which may extend up to 0.4-0.6 mm on the instrument tip in case of a well-skilled microsurgeon may cause diffi culties in any fi eld of microsurgery, in spite of using different armrests. The limit of correctness of medical robots is about 0.1 mm so far, but the application of these machines is expensive and not convenient for surgeons because the direct touch via microinstruments with living tissues is impossible. MethodThe effectiveness of the fi ngertip support technique has been proven by randomized analysis by exact measuring of the reduction of tremor. ResultsThe 0.1 mm precision could be reached by fi ngertip support. This extra precise work has not been available by hand so far. ConclusionThe signifi cant effect of fi ngertip support technique in neurosurgery has been certifi ed and published by exact measuring and clinical data.Our hypothesis could be the indication for trials in any microsurgical work.

“…One of the basic factors is physiologic tremor, what is impeding the surgeon and the development of accurate sutures [1]. By using the fingertip support technique, the tips of the thumb, index-and middle fingers are supported on the fixed platform (bridge) which overpasses the operational area [2]. This bridge is commercially available in different shapes and sizes (Bethlehembridge) [2].…”
