Abstract

A surgical instrument is provided including an outer housing shell defining a cavity, the outer housing shell defining an upper outer housing half and a lower outer housing half, wherein the upper outer housing half defines a longitudinal axis and an instrument module selectively insertable into the cavity of the outer housing shell. The instrument module includes an inner housing shell, at least one motor disposed within the inner housing shell, a control board being in electrical communication with the at least one motor and an energy source being in electrical communication with the at least one motor and the control board. The instrument module is inserted into the cavity of the outer housing shell in such a manner that the operative axis of the at least one motor is substantially parallel to the longitudinal axis of the upper outer housing half.

Claims

1. A surgical instrument, comprising:

an outer housing shell defining a cavity, the outer housing shell defining an upper outer housing half and a lower outer housing half, wherein the upper outer housing half defines a longitudinal axis; and

an instrument module selectively insertable into the cavity of the outer housing shell, the instrument module including;

an inner housing shell;

at least one motor disposed within the inner housing shell, the at least one motor including a drive shaft defining an operative axis of rotation;

a control board disposed within the inner housing and being in electrical communication with the at least one motor; and

an energy source disposed within the inner housing and being in electrical communication with the at least one motor and the control board;

wherein the instrument module is inserted into the cavity of the outer housing shell in such a manner that the operative axis of the at least one motor is substantially parallel to the longitudinal axis of the upper outer housing half.

2. The surgical instrument according to claim 1, wherein the outer housing shell is at least partially translucent.

3. The surgical instrument according to claim 1, wherein the outer housing shell is at least partially transparent.

4. The surgical instrument according to claim 1, wherein the upper outer housing half includes at least one speaker for providing feedback information related to tissue parameters and surgical instrument parameters measured during a surgical procedure.

5. The surgical instrument according to claim 1, wherein the upper outer housing half includes at least one viewing window for viewing a display screen disposed therein displaying information related to tissue parameters and surgical instrument parameters measured during a surgical procedure.

6. The surgical instrument according to claim 5, wherein the display screen includes at least one of numerical indicators and color indicators.

7. The surgical instrument according to claim 1, wherein the control board electrically communicates with at least one processor for enabling flow of electrosurgical energy between the energy source and the at least one motor.

8. The surgical instrument according to claim 1, wherein the lower outer housing half includes an instrument shell cover hingedly connected thereto, the instrument shell cover configured to swivel into place after the instrument module is inserted into the cavity of the outer housing shell.

9. The surgical instrument according to claim 1, wherein an instrument shell cover is attached to at least a portion of the lower outer housing half, such that the upper and lower outer housing halves attach to the instrument shell cover to form a secure connection.

10. The surgical instrument according to claim 1, wherein the outer housing shell defines at least one opening formed in a distal surface thereof for receiving the drive shaft therethrough when the instrument module is fully disposed in the outer housing shell.

11. The surgical instrument according to claim 10, wherein a seal is supported in the opening formed in the distal surface of the outer housing shell, wherein the seal founts a fluid-tight seal between the outer housing shell and the drive shaft.

12. The surgical instrument according to claim 1, wherein the instrument module includes a plurality of motors each including a drive shaft extending therefrom;

wherein the outer housing shell defines a plurality of openings formed in a distal surface thereof for receiving a respective drive shaft therethrough when the instrument module is fully disposed in the outer housing shell; and

wherein a seal is supported in each opening formed in the distal surface of the outer housing shell, wherein each seal forms a fluid-tight seal between the outer housing shell and the respective drive shaft.
