Abstract

A battery-powered, modular surgical device includes an electrically powered surgical instrument operable to surgically interface with human tissue and a handle assembly connected to the surgical instrument. The handle assembly has a removable hand grip and a handle body. The hand grip is shaped to permit handling of the surgical device by one hand of an operator, has an upper portion and a cordless internal battery assembly that powers the surgical instrument. The internal battery assembly has at least one energy storage cell. The handle body is operable to removably connect at least the upper portion of the hand grip thereto and create an aseptic seal around at least a portion of the hand grip when connected thereto and electrically couple the internal battery assembly of the hand grip to the surgical instrument and thereby power the surgical instrument for interfacing surgically with the human tissue.

Claims

1. A battery-powered, modular surgical device, comprising:

an electrically powered surgical instrument operable to surgically interface with human tissue; and

a handle assembly connected to the surgical instrument, the handle assembly having;

a removable hand grip;

shaped to permit handling of the surgical instrument by one hand of an operator; and

having an upper portion and a cordless internal battery assembly that powers the surgical instrument, the internal battery assembly having at least one energy storage cell; and

a handle body operable to;

removably connect at least the upper portion of the removable hand grip thereto and create an aseptic seal around at least a portion of the removable hand grip when connected thereto; and

electrically couple the internal battery assembly of the removable hand grip to the surgical instrument and thereby power the surgical instrument for interfacing surgically with the human tissue.

2. The surgical device according to claim 1, wherein at least one of the surgical instrument, the removable hand grip, and the handle body is disposable.

3. The surgical device according to claim 1, wherein the surgical instrument is comprised of a surgical cautery and cutting end effector assembly.

4. The surgical device according to claim 1, wherein the surgical cautery and cutting end effector assembly is an ultrasonic surgical cautery and cutting end effector assembly.

5. The surgical device according to claim 1, wherein the battery assembly is rechargeable.

6. The surgical device according to claim 1, wherein the at least one energy storage cell is a Lithium-based battery cell.

7. The surgical device according to claim 1, wherein the surgical instrument is comprised of at least one pivoting jaw member and a cutting blade opposing the jaw member.

8. A battery-powered, modular surgical device, comprising:

an electrically powered surgical end effector assembly operable to surgically interface with human tissue; and

a removable hand grip shaped to permit handling thereof by one hand of an operator, the removable hand grip including at least one reusable battery;

electrically coupled to the surgical end effector assembly to power and thereby cause the surgical end effector assembly to operate; and

removably secured to the surgical end effector assembly such that the at least one reusable battery is selectively exposed to the surgical environment when removed therefrom.

9. The surgical device according to claim 8, wherein the surgical end effector assembly is comprised of a surgical cautery and cutting end effector assembly.

10. The surgical device according to claim 8, wherein the surgical cautery and cutting end effector assembly is an ultrasonic surgical cautery and cutting end effector assembly.

11. The surgical device according to claim 8, wherein the at least one reusable battery is rechargeable.

12. The surgical device according to claim 8, wherein the surgical end effector assembly is comprised of at least one pivoting jaw member and a cutting blade opposing the jaw member.

13. A removable battery assembly of a battery-powered surgical device having an electrically powered surgical instillment operable to surgically interface with human tissue, the removable battery assembly comprising:

a battery body outer shell having an upper portion, a lower portion, and defining a shell interior, the battery body outer shell;

being a hand grip of the surgical device when secured to the surgical instrument;

being shaped to permit handling of the surgical device by one hand of an operator;

having, in the shell interior, a cordless rechargeable battery that powers the surgical instrument;

having an upper portion shaped to removably connect to a portion of the surgical instrument and create an aseptic seal around at least a part of the upper portion when connected thereto and be selectively exposed to the surgical environment when removed therefrom; and

having exterior conductors electrically coupled to the cordless rechargeable battery and positioned to supply at least power to operate the surgical instrument.

14. The assembly according to claim 13, wherein the surgical instrument is comprised of a surgical cautery and cutting end effector assembly.

15. The assembly according to claim 14, wherein the surgical cautery and cutting end effector assembly is an ultrasonic surgical cautery and cutting end effector assembly.

16. The assembly according to claim 13, wherein the surgical instrument is comprised of at least one pivoting jaw member and a cutting blade opposing the jaw member.
