Title:
バネ無しのハンドピース用チェックバルブ
Document Type and Number:
Japanese Patent JP2012503525
Kind Code:
A
Abstract:
A hand piece for a surgical instrument is provided. The handpiece has an inlet, a chamber (with upstream and downstream portions), a flow control member, a pulse engine, and an outlet. The inlet communicates with the upstream portion of the chamber. The downstream portion of the chamber communicates with the engine. The engine communicates with the outlet. In a closed position of the member, flow from the inlet moves the member to the open position thereby allowing flow through the flow path. In the open position, pulses from the engine move the member to the closed position before pulses from the pulse engine can flow through the flow path, thereby preventing flow through the flow path.
