Energy stored in spring with controlled release
First Claim
1. A surgical instrument comprising:
- a handle having an elongate tubular member extending distally from the handle;
an end effector provided on a distal end of the elongate tubular member;
a driver mounted for movement relative to the elongate tubular member to operate the end effector;
an energy storage mechanism for storing and providing energy to move the drive rod; and
an actuation mechanism operable on the energy storage mechanism to control the rate of release of the energy stored in the energy storage mechanism.

Abstract
There is provided a surgical instrument including a handle having an elongated tubular member extending distally from the handle and one or more end effectors mounted on the distal end of the elongate tubular member. A driver is movably mounted within the handle and elongate tubular member in order to operate the end effectors. The surgical instrument includes an energy storage mechanism for storing and providing energy to move the driver and thereby actuate the surgical instrument. Various actuation mechanisms are disclosed which are operable on the energy storage mechanism to control the rate of release of the energy stored in the energy storage mechanism.

13. A surgical instrument comprising a handle having an elongate tubular member extending distally from the handle;
-
an end effector provided on a distal end of the elongate tubular member;
a driver mounted for movement relative to the elongate tubular member to operate the end effector;
a compressible spring mounted in the handle;
a piston having a piston rod affixed thereto;
the piston engageable with the spring in response to movement of the piston rod;
a gear mechanism on a first end of the piston rod, the gear mechanism being engageable with the driver to move the driver relative to the handle;
an actuation mechanism operable on the energy storage mechanism to restrain the spring and control the rate of release of energy stored in the energy storage mechanism. - View Dependent Claims (14, 15, 16)

17. A surgical instrument for driving an end effector comprising:
-
a handle having an elongate tubular member extending from the distal end of the handle;
a driver movable within the elongate tubular member and operable on an end effector;
an energy storage mechanism at least partially positioned within the handle and operable on the driver to move the driver within the elongate tubular member;
an actuation mechanism operable on the energy storage mechanism to control the rate of release of the energy stored in the energy storage mechanism. - View Dependent Claims (18, 19, 20)
