If you're looking to maintain and control good exposure then its crucial to have a bloodless, dry field paramount to good exposure. Sponging and suction should be done so as to give the best exposure with the least interruption of the surgeon's dissection. The sucker tip of your surgical instrument should lead in front of your cutting using your forceps, The medical doctor should be sure not to risk his view of the surgical operation at hand. Also he should be aware at which direction any of his surgical instruments are heading including: forceps, surgical scissors, dilators, etc. The doctors assistants should be on aware of the surgeon when hes using his surgical instruments sucking or sponging, it is better to synchronize the wound, as opposed to the surgeon removing his surgical instruments, then get rid of the sucker tip after aspirating all of the free blood, may re-accumulate before the surgeon is ready to proceed with his work. It is, therefore, better to synchronize removal of the aspirating tip or sponge just as the doctor enters the wound.
When you have a terminal opening, it is possible to come across some danger from the sucker tips. A finger hole on the handle of such surgical instruments is usually provided to limit the suction if the terminal opening is occluded against tissue. The idea of covering up the finger hole to whenever one desires to suck, to avoid the suction, let go of the hole, it will "accentuate the positive" and can avoid an inadvertent trauma.
When aspirating on delicate tissue, the interposition of fabric such as a sponge or cottonoid will allow the elimination of fluid without the hazard of tissue trauma. Sucker tips are very important in this type of circumstance. There are a lot of different kind of sucker tips, from very large ones with holes that big enough to clot up big amounts of blood, to the more fine tips.
