Latching mechanism for forceps
First Claim
1. A surgical instrument comprising:
- a shaft having a proximal and a distal end;
a housing connected to the proximal end of the shaft;
an actuation assembly having a first lever and a second lever, each of the first and second levers being pivotably connected to the housing;
an end effector assembly operatively connected to the distal end of the shaft, the end effector assembly having a pair of opposing jaw members;
a drive rod slidably disposed within the shaft and connected to the actuation assembly, the drive rod being operable by the actuation assembly to actuate the opposing jaw members between open and closed positions; and
a latching mechanism operatively associated with the actuation assembly and drive rod for maintaining the jaw members in the closed position.

Abstract
The present disclosure relates to a surgical instrument which includes a shaft having a proximal end and a distal end and a housing connected to the proximal end of the shaft. The instrument may further include an actuation assembly having a first lever and a second lever, each pivotally connected to the housing. An end effector assembly is operatively connected to the distal end of the shaft and includes a pair of opposing jaw members. The instrument may further include a drive rod slidably disposed within the shaft and connected to the actuation assembly, the drive rod being operable by the actuation assembly to actuate the opposing jaw members between open and closed positions. A latching mechanism may be provided which is operatively associated with the actuation assembly and drive rod for maintaining the jaw members in the closed position.

15. A surgical instrument comprising:
-
a shaft having a proximal end and a distal end;
a housing connected to the proximal end of the shaft;
an actuation assembly having a first lever and a second lever, each lever being pivotably connected to the housing;
an end effector assembly operatively connected to the distal end of the shaft, the end effector assembly having a pair of opposing jaw members;
a drive rod slidably disposed within the shaft and connected to the actuation assembly, the drive rod being operable by the actuation assembly to actuate the opposing jaw members between open and closed positions;
a first link and a second link each having a distal end pivotally connected to the first and second levers respectively;
a mandrel fixedly mounted to the drive rod, proximal ends of the first and second links being pivotally attached to the mandrel; and
a biasing member configured to bias the actuation assembly to one of an open and closed condition. - View Dependent Claims (17)
