Dermatome swivel double acting valve

摘要

A dermatome having a handle and an attachment including a valve, where the valve may include a first bobbin at least partially defining a first flow path and a second flow path, a second bobbin at least partially defining a first flow path, an inlet port at least partially defined by the second bobbin and an outlet port at least partially defined by the first bobbin. The ports of the valve may open in response to an application of a mechanical act to the attachment and the ports may close in response to the absence or removal of the mechanical act.

1. A dermatome comprising:
a handle extending from a cutting head; and a valve connected to the handle, the valve including:
a first bobbin having a medial flange portion and at least partially defining a first flow path and a second flow path;a second bobbin in adjustable communication with the first bobbin and at least partially defining the first flow path;an inlet port at least partially defined by the second bobbin, the inlet port communicating with an inlet flow through the first flow path; andan outlet port at least partially defined by the first bobbin, the outlet port communicating with an outlet flow through the second flow path; andwherein in response to an application of a mechanical act to the valve, the first flow path is automatically opened at the inlet port and the second flow path is automatically opened at the outlet port; andwherein in response to an absence of the mechanical act, the first flow path is automatically closed at the inlet port and the second flow path is automatically closed at the outlet port.
