Coupling member configured for use with surgical devices
First Claim
1. A surgical apparatus comprising:
- a surgical actuating device including a shaft having a distal end supporting a first coupling member, the first coupling member including at least one pair of apertures; and
a reload including a tool assembly, the reload including a second coupling member including a locking assembly, the second coupling member including a pair of spring pins that are positioned to be received within the at least one pair of apertures, the spring pins being movable from an inward position to a radial outward position, the locking assembly including a lock plate that is moveable from a first position located between the spring pins to prevent movement of the spring pins from the radial outward position to the inward position to a second position spaced from the spring pins, wherein in the radial outward position the spring pins are received within the apertures of the first coupling member to secure the reload to the surgical actuating member and wherein when the lock plate is in the first position, the reload cannot be separated from the surgical actuating device.

Abstract
A surgical apparatus is provided. The surgical apparatus includes a surgical actuating device including a shaft having supporting a first coupling member. The first coupling member includes one or more pairs of apertures. The reload includes a second coupling member including a locking assembly. The second coupling member includes a pair of spring pins positionable within the pair of apertures. The spring pins being movable from an inward position to a radial outward position. The locking assembly includes a lock plate that is moveable from a first position located between the spring pins to a second position spaced from the spring pins. In the radial outward position, the spring pins are received within the apertures of the first coupling member to secure the reload to the surgical actuating member and when the lock plate is in the first position, the reload cannot be separated from the surgical actuating device.

10. A surgical apparatus comprising:
-
a surgical actuating device including a shaft having a distal end supporting a first coupling member, the first coupling member including at least one pair of apertures; and a reload including a tool assembly, the reload including a second coupling member including a locking assembly, the second coupling member including a pair of spring pins that are positioned to be received within the at least one pair of apertures, the spring pins being movable from an inward position to a radial outward position, the locking assembly including a lock plate that is moveable from a first position located between the spring pins to prevent movement of the spring pins from the radial outward position to the inward position to a second position spaced from the spring pins, wherein in the radial outward position the spring pins are received within the apertures of the first coupling member to secure the reload to the surgical actuating member and wherein when the lock plate is in the first position, the reload cannot be separated from the surgical actuating device, wherein the lock plate includes a clevis at a top portion thereof, the clevis being configured to connect to a proximal end of a plunger of the locking assembly, and wherein the plunger supports a spring for biasing the lock plate into engagement with the pair of spring pins when a knife of a cartridge of the tool assembly is fired.
