VALVE ARRANGEMENT FOR SURGICAL INSTRUMENTS AND VALVE CAGE FOR ACCOMMODATING THE VALVE ARRANGEMENT |
摘要 |
The invention relates to a valve arrangement for surgical instruments, particularly trocars, such as those used for minimally invasive operations, e.g. operations involving laparoscopic techniques. The invention also relates to a valve cage for accommodating the valve arrangement. The valve arrangement comprises a valve body made of closed-cell, gas-tight foam material having at least one slot, which passes through the valve body and which is provided for introducing a surgical instrument guided inside the trocar. The valve cage is provided in the form of a housing whose shape and size are adapted to the outer dimensions of the valve body. The housing can be joined to a conventional trocar sleeve in a sealed and detachable manner. |
