Magnetic closure mechanism for hemostat
First Claim
1. A hemostat comprising:
- a housing having a shaft extending distally therefrom, said shaft having an end effector assembly attached at a distal end thereof;
a pair of first and second handles connected to the housing and operatively connected to the end effector assembly, at least one of said handles moveable relative to the other said handles to effectively actuate the end effector assembly; and
a magnetic closure mechanism having a first magnet having a first magnetic potential connected to said first handle and a second magnet having a second magnetic potential connected to said second handle, wherein said first and second magnets are securely engageable with one another when said handles are moved from a first spaced configuration to a second closer configuration.

Abstract
A hemostat includes a housing which has a shaft extending distally therefrom. The shaft has an end effector assembly distally attached thereto. The hemostat also includes a pair of first and second handles which are connected to the housing. The first and second handles are operatively connected to the end effector assembly. At least one of the first and second handles are moveable relative to the other handle to effectively actuate the end effector assembly. The hemostat further includes a magnetic closure mechanism which has a first magnet connected to the first handle and a second magnet connected to the second handle. The first and second magnets each have a magnetic potential and are securely engageable with one another when the handles are moved from a first spaced configuration to a second closer position.

16. A hemostat comprising:
-
a housing having a shaft extending distally therefrom, said shaft having an end effector assembly attached at a distal end thereof, wherein said end effector assembly includes opposing first and second jaw members, said jaw members adapted to connect to an electrical energy source such that said jaw members can selectively apply electrical energy through tissue held therebetween;
a pair of first and second handles connected to the housing and operatively connected to the end effector assembly, at least one of said handles moveable relative to the other of said handles to effectively actuate the end effector assembly; and
a magnetic closure mechanism having a first magnet having a first magnetic potential connected to said first handle and a second magnet having a second magnetic potential connected to said second handle, wherein said first and second magnets are securely engageable with one another when said handles are moved from a first spaced configuration to a second closer configuration and said magnetic closure mechanism maintains a closure pressure between the opposing jaw members within a predefined pressure range. - View Dependent Claims (17, 18)

19. A hemostat comprising:
-
first and second shafts pivotably engaged for movement relative to one another from a first spaced configuration to a second closer configuration, each of said first and second shafts including respective jaw members at a distal end thereof and respective handles at a proximal end thereof, said jaw members disposed in opposing relation relative to one another; and
a magnetic closure mechanism having a first magnet having a first magnetic potential connected to said first handle and a second magnet having a second magnetic potential connected to said second handle, wherein said first and second magnets are securely engageable with one another when said handles are moved from a first spaced configuration to a second closer configuration and said magnetic closure mechanism maintains a closure pressure between the opposing jaw members within a predefined pressure range.
