TWIN FORCEPS FOR SINGLE ACCESS LAPAROSCOPY

摘要

The patent is relative to a new instrument for single access laparoscopy that tries to overcome the limits of the present instrumentation of this technique, that usually allows to use only one forceps, which does not allow to keep the tissues tenses to work with the surgical instrument. To overcome this limitation, the proposed instrument presents two arms, presenting a diameter equal to half of the main body, while in the direction perpendicular to this these arms can have an bigger dimension, provided its shape be entirely circumscribed by the external dimension of the initial body, and each bearing at the tip a forceps, mounted on two auxiliary arms. The internal mechanism allows opening the two arms, while the forceps bend toward the inside, keeping their configuration, being all this controlled by a single command. Two additional commands allow then to open and close the forceps individually, and each command can be locked in any position. The forceps can be opened in any direction relative to the plane of the arms, as well as it is possible that one or both of the forceps are replaced by a tool of a different type.
