Method and system for sterilizing an electrosurgical instrument
An apparatus and method for use in sterilizing a surgical instrument is provided. The apparatus includes a surgical instrument that includes a housing having a shaft extending therefrom. The shaft includes one or more grooves defined therein that extends at least partially along the length thereof. The one or more grooves is configured to allow a sterilant passage therethrough. The apparatus also includes a jacket that encloses the shaft and allows the sterilant to travel along the one or more grooves.
1. A surgical instrument, comprising:
a housing; and
a shaft extending distally from the housing and having an outer surface and an inner surface, the shaft including:
at least one groove defined in the outer surface and extending at least partially along a length of the shaft; and
at least one aperture disposed within the at least one groove and extending to the inner surface of the shaft, the at least one aperture configured to allow a sterilant to pass therethrough to target specific areas of the surgical instrument prone to contamination; and
a jacket enclosing the shaft and configured to allow the sterilant to travel along the at least one groove.
2. The surgical instrument according to claim 1 , wherein the at least one groove is a plurality of grooves that extend the entire length of the shaft, each groove of the plurality of grooves disposed in fixed spatial relation to each other.
3. The surgical instrument according to claim 2 , wherein each groove of the plurality of grooves is disposed in general orthogonal relation to each other.
4. The surgical instrument according to claim 1 , wherein the at least one groove has a depth of about 0.002 inches and a width of about 0.004 inches.
5. The surgical instrument according to claim 1 , wherein the jacket is a heat shrink wrap.
6. The surgical instrument according to claim 5 , wherein the heat shrink wrap is formed from a polymer plastic film.
7. The surgical instrument according to claim 1 , wherein the sterilant includes ethylene oxide.
8. The surgical instrument according to claim 7 , wherein the sterilant includes a mixture of ethylene oxide and one of chlorofluorocarbon or carbon dioxide.
9. The surgical instrument according to claim 1 , wherein the at least one groove includes one of an arcuate or square cross-section.
10. The surgical instrument according to claim 1 , wherein the at least one groove has a proximal end disposed within the housing.
11. A laparoscopic instrument, comprising:
a housing; and
a shaft extending distally from the housing and having an outer surface and an inner surface, the shaft including:
at least one tunnel defined in the outer surface and extending at least partially along a length of the shaft; and
at least one aperture disposed within the at least one tunnel and extending to the inner surface of the shaft, the at least one tunnel configured to allow a sterilant to pass therethrough to target specific areas of the surgical instrument prone to contamination; and
a jacket enclosing the shaft and configured to allow the sterilant to travel along the at least one tunnel.
12. The laparoscopic instrument according to claim 11 , wherein the at least one tunnel is a plurality of tunnels that extend the entire length of the shaft, each tunnel of the plurality of tunnels disposed in fixed spatial relation to each other.
13. The laparoscopic instrument according to claim 12 , wherein each tunnel of the plurality of tunnels is disposed in general orthogonal relation to each other.
14. The laparoscopic instrument according to claim 11 , wherein the jacket is a heat shrink wrap.
15. The laparoscopic instrument according to claim 14 , wherein the heat shrink wrap is formed from a polymer plastic film.
16. The laparoscopic instrument according to claim 11 , wherein the sterilant includes ethylene oxide.
17. The laparoscopic instrument according to claim 16 , wherein the sterilant includes a mixture of ethylene oxide and one of chlorofluorocarbon or carbon dioxide.
18. The laparoscopic instrument according to claim 11 , wherein the at least one tunnel has a proximal end disposed within the housing.
