Supracervical hysterectomy, bilateral salpingectomy, robot-assisted laparoscopy (DaVinci)

• Positioning is done in lithotomy position (or more safely on spreadable straight leg supports), ideally on a large vacuum cushion or non-slip mat
• It is recommended to adduct both arms (caution: cotton wrapping when positioning with a cloth sling), or to abduct one arm on the side of the robot
• For leg positioning, padded "boots" are recommended so that the legs can be moved separately and covered sterilely if necessary. Alternatively, the legs can be positioned in leg holders with fixation in these (caution: compartment syndrome).
• The legs should be adjustable via the OR table control during the procedure
• Shoulder supports bilaterally to prevent the patient from slipping on the OR table
• For longer procedures, application of pneumatic compression cuffs for the legs for thrombosis prophylaxis
• Attachment of a cervical adapter

Note: It is important to note the risk of injury to the patient from the instruments if the patient slips. With coupled tables in the Xi System, intraoperative position changes are possible without uncoupling. If the "Table-Motion" technique is not available, the surgical robot must always be undocked and removed from the OR table before any position change

Creation of a capnoperitoneum by inserting a Veress needle approximately 20 cm away from the target anatomy (usually periumbilical). The three to four 8 mm robotic trocars are positioned in a straight, horizontal line (Xi) or a slightly curved line towards the operative site (X, SI). The distance between each trocar is ideally 8 cm (minimum 7 cm to maximum 10 cm). The 10 or 12 mm assistant trocar can be placed in the lower abdomen, cranial to the trocars, or as an additional trocar along the straight line, depending on the assistant's positioning at the operating table and the surgeon's preference (see illustration). The patient is positioned at the end of the operating table and then placed in a steep Trendelenburg position (approximately 30°). The table tilt is adjusted as necessary for anesthetic or surgical requirements. The laser marking is aligned so that the crosshair points directly at the camera trocar (Xi). The Da Vinci system is then aligned. The arms are connected (docked) with the three to four 8 mm robotic trocars. Subsequently, the instruments are introduced under visual control and parked under the anterior abdominal wall.

Caution: The trocars must be positioned with the wide black ring at the level of the muscular abdominal wall (so-called remote center) to avoid injury during movement.

Note: Depending on the operating room and the surgeon's preference, the positioning of the da Vinci "patient cart" and the trocars may vary.
