Abstract

Various surgical instruments are disclosed. At least one surgical instrument includes an instrument mounting portion configured to mount to a robotic surgical system. The instrument mounting portion includes an interface to mechanically and electrically interface to the surgical instrument adapted for use with the robotic surgical system. A fluid management system is contained within the instrument mounting portion. The fluid management system includes a first container to contain a first fluid agent to be dispensed.

First claim

What is claimed is:

1. A surgical instrument, comprising:
an instrument mounting portion configured to releasably mount to a movable arm of a robotic surgical system, the instrument mounting portion comprising:
an interface configured to mechanically and electrically interface the surgical instrument with the robotic surgical system; and
a housing connected to the interface;

a fluid management system positioned within the instrument mounting portion, the fluid management system comprising:
a first container fixedly positioned within the housing; and
a fluidic channel positioned within the housing and fluidically coupled to the first container, wherein the first container contains a first fluid agent to be dispensed;

a drive mechanism positioned within the instrument mounting portion, wherein the drive mechanism is coupled to the fluid management system;
a shaft assembly coupled to the instrument mounting portion, the shaft assembly comprising a second fluidic channel fluidically coupled to the fluidic channel; and
an end effector coupled to the shaft assembly, the end effector comprising a third fluidic channel fluidically coupled to the second fluidic channel.

2. The surgical instrument of claim 1 , wherein the end effector is coupled to the drive mechanism.

3. The surgical instrument of claim 1 , further comprising a pump positioned within the housing, operatively coupled to the drive mechanism and fluidically coupled to the first container and the fluidic channel.

4. The surgical instrument of claim 3 , wherein the pump is a peristaltic pump.

5. The surgical instrument of claim 4 , further comprising a flexible fluidic channel portion, a first roller and a rigid surface, wherein:
the first roller is operatively coupled to the drive mechanism; and
the flexible fluidic channel portion is operatively coupled between the first roller and the rigid surface to compress the flexible fluidic channel portion at at least one point between the first roller and the rigid surface during a revolution of the first roller.

6. The surgical instrument of claim 5 , further comprising a second roller, wherein the flexible fluidic channel portion is operatively coupled between at least the first roller and the second roller, wherein each of the first and second rollers is operatively coupled to the drive mechanism to compress the flexible fluidic channel portion at at least one point between the first and second rollers during a revolution of the first and second rollers.

7. The surgical instrument of claim 1 , further comprising:
a second container fixedly positioned within the housing; and
a three-port fitting positioned within the housing, the three-port fitting having two inlet ports fluidically coupled to the respective first and second containers and an outlet port fluidically coupled to the fluidic channel.

8. The surgical instrument of claim 7 , further comprising a pump positioned within the housing, operatively coupled to the drive mechanism and fluidically coupled to the first and second containers and the fluidic channel.

9. The surgical instrument of claim 8 , further comprising:
first and second rollers operatively coupled to the drive mechanism;
a first flexible fluidic channel portion fluidically coupled to the first container; and
a second flexible fluidic channel portion fluidically coupled to the second container;
wherein, the first and second flexible fluidic channel portions are operatively coupled between at least the first and second rollers to compress the first and second flexible fluidic channel portions at at least one point between the first and second rollers during a revolution of the first and second rollers.

10. The surgical instrument of claim 1 , further comprising a source of pressurized gas positioned within the housing and fluidically coupled to the first fluidic channel.

11. A surgical instrument, comprising:
an ultrasonic surgical system comprising an ultrasonic transducer, an ultrasonic waveguide acoustically coupled to the ultrasonic transducer, and an end effector comprising an ultrasonic blade acoustically coupled to the ultrasonic waveguide;
an instrument mounting portion coupled to the ultrasonic surgical system and configured to releasably mount to a movable arm of a robotic surgical system, the instrument mounting portion comprising:
an interface configured to mechanically and electrically interface the surgical instrument with the robotic surgical system; and
a housing connected to the interface;

a fluid management system positioned within the instrument mounting portion, the fluid management system comprising:
a first container fixedly positioned within the housing; and
a fluidic channel positioned within the housing and fluidically coupled to the first container, wherein the first container contains a first fluid agent to be dispensed;

a drive mechanism positioned within the instrument mounting portion, wherein the drive mechanism is coupled to the fluid management system;
a shaft assembly coupled to the instrument mounting portion, the shaft assembly comprising a second fluidic channel fluidically coupled to the fluidic channel; and
an end effector coupled to the shaft assembly, the end effector comprising a third fluidic channel fluidically coupled to the second fluidic channel.

12. The surgical instrument of claim 11 , wherein the end effector is coupled to the drive mechanism.

13. The surgical instrument of claim 11 , further comprising a pump positioned within the housing, operatively coupled to the drive mechanism and fluidically coupled to the first container and the fluidic channel.

14. The surgical instrument of claim 13 , wherein the pump is a peristaltic pump.

15. The surgical instrument of claim 14 , further comprising a flexible fluidic channel portion, a first roller and a rigid surface, wherein:
the first roller is operatively coupled to the drive mechanism; and
the flexible fluidic channel portion is operatively coupled between the first roller and the rigid surface to compress the flexible fluidic channel portion at at least one point between the first roller and the rigid surface during a revolution of the first roller.

16. The surgical instrument of claim 15 , further comprising a second roller, wherein the flexible fluidic channel portion is operatively coupled between at least the first roller and the second roller, wherein each of the first and second rollers is operatively coupled to the drive mechanism to compress the flexible fluidic channel portion at at least one point between the first and second rollers during a revolution of the first and second rollers.

17. The surgical instrument of claim 11 , further comprising:
a second container fixedly positioned within the housing; and
a three-port fitting positioned within the housing, the three-port fitting having two inlet ports fluidically coupled to the respective first and second containers and an outlet port fluidically coupled to the fluidic channel.

18. The surgical instrument of claim 17 , further comprising a pump positioned within the housing, operatively coupled to the drive mechanism and fluidically coupled to the first and second containers and the fluidic channel.

19. The surgical instrument of claim 18 , further comprising:
first and second rollers operatively coupled to the drive mechanism;
a first flexible fluidic channel portion fluidically coupled to the first container; and
a second flexible fluidic channel portion fluidically coupled to the second container;
