Surgical first assistant1/6/2024 ![]() Care is taken not to devascularize upper layers of tissue.įirst assistant’s knowledge and skill level Holding an instrument or scissors in a steady position with the index finger on the box lock hinge and the thumb and ring finger partly in the ring handles for ease of release.ĭissection of subsurface tissue planes. Suturing three opposing points of a tubular structure so that the distance between two points can be approximated in a straight line. Can be done by sharp dissection or electrocoagulation. ![]() A small portion of the ring finger may be situated within the opposing ring of the handle.ĭisplacement of a structure by pulling the tissue in an opposite direction to facilitate sharp or blunt dissection of tissue planes.Ĭutting across natural anatomic lines. Method of holding an instrument in which the ring handle is secured in the palm at the base of the thumb instead of placing the thumb through the ring. (verb) The act of sewing tissues (noun), a thread used for sewing tissue in surgery. A physician, RNFA, SA, PA, or CST specially trained and certified as a CFA. Member of the sterile team who provides exposure and hemostasis during a surgical procedure. On occasion, a rigid suction tip can be used to remove fluids and retract tissues simultaneously. Various styles of tips and tip protectors are used. Negative pressure used to clear the visual field of blood and body substances. The constant state of skin position over the framework of the body. The preferred way to sponge is to blot or pat the area so as not to remove biologic clots. A form of blunt dissection.Ī method of providing exposure by removal of blood and fluid from the surgical site. Separation of muscle tissue along the fascial layers. Tension factors largely in the final healing of the incision and the appearance of the scar. The turgor of the skin that is either static or dynamic. Scalpel is dragged laterally across tissues to separate cell layers rather than full tissue layers. Care is taken not to disrupt vascularization of the elevated tissue.ĭisplacement of structures by use of the hand or an instrument to expose the surgical site. Perpendicular countertraction is placed on superficial tissues as large areas are undermined by dissection. Press cutting can be a form of intentional puncture. Scalpel is pushed into the tissue rather than slid to incise. The scalpel is held perpendicular to the tissue during incision. The intersection of surfaces at right angles. This method can be used for countertraction with some manual retractors. The working end can be presented and made functional by a rotation of the wrist. Method of holding an instrument where the working end is nested in the palm of the hand of the assistant while the fingers remain free to grasp other items in the field. The act of tying or occluding an anatomic structure. Natural lines along skin caused by tension inherent in the structure of the dermal-epidermal layers. Scalpel is used in a perpendicular position to slice tissue in a linear direction. The stress on skin caused by underlying musculature, joints, and body motion. Separation of tissue planes by sharp or blunt means. Tissue planes where the natural line of tissue growth permits dissection between areas that maintain anatomic structure. The edge of a Teflon-coated cautery blade is placed against an instrument clamped to patient’s tissue below the level of the operator’s hand before activation of the current. ![]() The flat side of a metal cautery blade is placed in contact with a clamped instrument below the level of the operator’s hand before activation of the current. Creating a patent connection between two tubular structures by use of suture or specialized staples.Ī method of applying the active electrode of a monopolar cautery against an instrument clamped to the patient’s tissue for the purpose of spot hemostasis.
