Abstract
An improved surgical device for performing thoracostomies and laparoscopies wherein the escape of air from the chest cavities or gas from the abdomen during such operations is prevented. The device includes a stylet holder wherein the holder includes needle halves having cooperating portions thereon for sealing off fluid flow when the portions are brought into contact. The stylet includes a needle having a bulged sharpened end adapted to seal off fluid flow so that fluid flows only through the needle. When the needle is withdrawn from between the needle halves, the needle halves are forced apart then mate so that the cooperating portions engage and seal off fluid flow.
