Keyhole surgery set=up

摘要

Fibrin etc adhesives are available to prevent gas transferring from the abdominal cavity into the body tissue assisted by artificial peritoneum lesions, and devices and instruments (1-4) are available to guard against interstitial central (and latent) emphysema in the event of tissue splits. The operating surgeon instals variably inflated balloons within the stomach cavity to form a tunnel to the focus or diseased organ, and the induced pressure of the balloons can be reduced at will. Vacuum sones (1,2,3) and associated pumps (P) draw off the air and gas from the stomach cavity, using diffusion for the retroperitoneal space, with resorption assisted by latent emphysema in the trunk. Long-stem injection syringes with short cannula for perhydro are also used to expand the cavity of hollow organs by aseptic oxygen foam, at the same time tightening the walls of the organ and associated blood vessels. The vacuum sondes are in the form of glass, metal or plastics tubes or again in hose form, being flexible and successively perforated in their walls.
