Abstract

A surgical system including a surgical instrument and a protection device is included. The surgical system includes a surgical instrument having an extension assembly releasably coupled thereto. The extension assembly includes a trocar member disposed within a distal end of the extension assembly and the trocar member includes an engagement feature defined in an outer surface thereof. The protection device is releasably coupled to the engagement feature of the trocar member, thereby providing a barrier adjacent a tip of the trocar member. A method of sterilizing a surgical instrument is also provided.

Claims

1. A surgical system, comprising:

a surgical instrument including an extension assembly releasably coupled thereto, the extension assembly including a trocar member disposed within a distal end of the extension assembly and extending therefrom, the trocar member terminating at a tissue piercing tip, the trocar member including an annular groove defined in an outer surface thereof; and

a protection device defining a cavity therein configured to receive a portion of the trocar member therein such that the tissue piercing tip of the trocar member is enveloped by the protection device, wherein the protection device is releasably coupled to the annular groove of the trocar member thereby providing a barrier adjacent the tissue piercing tip of the trocar member,

wherein the protection device further includes a plurality of legs disposed on a first end portion thereof, the plurality of legs extending axially therefrom,

wherein a second end portion of the protection device defines a planar configuration, the second end portion of the protection device including a rectangular base having an outer perimeter greater than an outer diameter of a housing of the surgical instrument.

2. The surgical system according to claim 1, wherein the plurality of legs terminate in a barb defined on an inner surface thereof, the barb configured to releasably engage the annular groove of the trocar member of the surgical instrument.

3. The surgical system according to claim 1, wherein the annular groove of the trocar member is a lip defined in the outer surface thereof, the lip configured to engage a complimentary engagement feature disposed on the protection device.

4. The surgical system according to claim 1, wherein a second end portion of the protection device includes a conical configuration defining a blunt tip, thereby inhibiting a clinician from contacting the tip of the trocar member.

5. The surgical system according to claim 1, wherein an annular groove is defined in an outer surface of the protection device, the annular groove configured to allow grasping of the protection device.

6. The surgical system according to claim 1, wherein the protection device is formed from a material suitable for use in a sterilization process.

7. The surgical system according to claim 1, wherein a second end portion of the protection device includes a flange disposed thereon configured for grasping.

8. The surgical system according to claim 1, wherein the second end portion of the protection device includes a flange having an outer diameter greater than an outer diameter of a housing surrounding the trocar member.

9. A method of sterilizing a surgical device, comprising:

providing a surgical instrument, including an extension assembly releasably coupled to the surgical instrument including a trocar member disposed within a distal end portion thereof and extending therefrom, the trocar member terminating at a tissue piercing tip, wherein at least a portion of the trocar member protrudes from the distal end portion of the extension assembly, the trocar member including an annular groove defined within an outer surface thereof;

providing a protection device defining a cavity therein configured to receive a portion of the trocar member therein such that the tissue piercing tip of the trocar member is enveloped by the protection device, wherein the protection device is configured to be releasably coupled to the annular groove of the trocar member,

wherein the protection device further includes a plurality of legs disposed on a first end portion thereof, the plurality of legs extending axially therefrom,

wherein a second end portion of the protection device defines a planar configuration, the second end portion of the protection device including a rectangular base having an outer perimeter greater than an outer diameter of a housing of the surgical instrument;

advancing the protection device over the trocar member and partially within a cavity defined within the distal end portion of the extension assembly until the protection device releasably engages the annular groove of the trocar member, thereby providing a barrier adjacent the tissue piercing tip of the trocar member;

removing the extension assembly, with the protection device releasably attached thereto, from the surgical instrument; and

placing the extension assembly, with the protection device releasably attached thereto, into a sterilization chamber.

10. The method according to claim 9, wherein providing a protection device includes the plurality of legs terminating in a barb defined on an inner surface thereof, wherein each barb of the plurality of legs engages the annular groove of the trocar member, thereby releasably coupling the protection device to the trocar member.

11. The method according to claim 9, wherein providing a protection device includes the protection device having an annular groove defined in an outer surface of thereof, the annular groove configured to allow grasping of the elongate body.

12. The method according to claim 9 wherein providing a protection device includes the protection device is constructed of a material suitable for use in a sterilization process.

13. The method according to claim 9, wherein providing a protection device includes a second end portion of the protection device including a flange disposed thereon configured for grasping.

14. The method according to claim 9, wherein providing a surgical instrument further includes an adapter assembly configured to be selectively secured to the surgical instrument on a first end and selectively secured to the extension assembly on a second end.

15. The method according to claim 14, wherein placing the extension assembly, with the protection device releasably attached thereto, into a sterilization chamber includes placing the adapter assembly and the extension assembly, including the protection device releasably attached thereto, into a sterilization chamber.
