Abstract

A surgical generator for providing a drive signal to a surgical device may have a receptacle assembly having a receptacle body, a flange and a central protruding portion. The outer periphery of the central protruding portion may have at least one curved section and at least one linear section. Additionally, a surgical instrument may comprise an electrical connector assembly having a flange. The flange may comprise at least one curved section and at least one linear section. In some embodiments, A surgical instrument system may comprise a surgical generator, a surgical instrument comprising a connector assembly, and an adapter assembly operatively coupled to the receptacle assembly and the connector assembly.

Claims

1. A surgical generator for providing a drive signal to a surgical device, the surgical device comprising a connector assembly, the surgical generator, comprising:

a surgical generator body defining an aperture; and

a receptacle assembly positioned in the aperture, the receptacle assembly comprising;

a receptacle body;

a flange having an inner wall and an outer wall, the inner wall comprised of at least one curved section and at least one linear section, the inner wall defining a cavity; and

a central protruding portion positioned in the cavity, the central protruding portion defining a central recess, the central recess defining a sidewall and a seat, wherein the central recess is configured to receive a ferrous element located in the connector assembly, the central protruding portion comprising;

a plurality of sockets arranged about the central recess;

a magnet positioned in abutting arrangement with the seat, wherein the magnet is configured to attract the ferrous element and translate the ferrous element proximally to strike the magnet and produce an audible sound when the connector assembly of the surgical device is inserted into the receptacle assembly of the surgical generator; and

an outer periphery comprising at least one curved section and at least one linear section.

2. The surgical generator of claim 1, wherein the at least one curved section of the outer periphery is parallel to the at least one curved section of the inner wall.

3. The surgical generator of claim 2, wherein the at least one linear section of the outer periphery is parallel to the at least one linear section of the inner wall.

4. The surgical generator of claim 1, wherein the magnet is positioned proximate the central recess.

5. The surgical generator of claim 1, wherein the flange has a flange surface and the central protruding portion has central surface, wherein the flange surface is slanted with respect to the central surface.

6. The surgical generator of claim 5, wherein the surgical generator body comprises a slanted surface, wherein the aperture is positioned on the slanted surface, and wherein the slanted surface is substantially parallel to the flange outer surface.
