Abstract

A specimen retrieval device may comprise the specimen retrieval bag for retrieval biological materials, a hybrid shaft, a first collapsible arm, and a second collapsible arm. The hybrid shaft may comprise a proximal end and a distal end, wherein the distal end is flexible, and wherein the proximal end is rigid. The first collapsible arm may be located at the distal end of the hybrid shaft, and may include a first portion. The second collapsible arm may be located at the distal end of the hybrid shaft, may include a first portion and a second portion. The second portion of the second collapsible arm may extend distally beyond the first portion of the second collapsible arm. The specimen retrieval bag may have an open end and a closed end, and may be configured to be retained upon the first collapsible arm and the second collapsible arm.

Claims

1. A surgical instrument, comprising:

a hybrid shaft having a proximal end and a distal end, wherein the distal end is flexible, and wherein the proximal end is rigid;

a first collapsible arm located at the distal end of the hybrid shaft, wherein the first collapsible arm comprises a first portion;

a second collapsible arm located at the distal end of the hybrid shaft, wherein the second collapsible arm comprises a first portion and a second portion, wherein the second portion extends distally beyond the first portion; and

a bag having an open end and a closed end, wherein the bag is configured to be retained upon the first collapsible arm and the second collapsible arm.

2. The surgical instrument of claim 1, further comprising:

a knot pusher located at the distal end of the hybrid shaft;

an articulating joint, wherein the articulating joint connects the first collapsible arm to the hybrid shaft and the second collapsible arm to the hybrid shaft;

an outer sheath extending from a distal handle to the distal end of the surgical instrument; and

a proximal handle.

3. The surgical instrument of claim 2, wherein the hybrid shaft extends from the proximal handle to the distal end of the surgical instrument.

4. The surgical instrument of claim 2, wherein the outer sheath translates from an unfired position to a fired position upon translation of the distal handle towards the proximal handle.

5. The surgical instrument of claim 4, wherein the hybrid shaft, the first collapsible arm, the second collapsible arm, the bag, the articulating joint, and the knot pusher are contained within the outer sheath in the unfired position.

6. The surgical instrument of claim 4, wherein the first collapsible arm, the second collapsible arm, the bag, the articulating joint, and the knot pusher are removed from containment of the outer sheath in the fired position.

7. The surgical instrument of claim 6, wherein the outer sheath translates from the fired position to a retracted position upon translation of the distal handle from the proximal handle.

8. The surgical instrument of claim 7, wherein the first collapsible arm, the second collapsible arm, and the articulating joint are contained within the outer sheath in the retracted position.

9. The surgical instrument of claim 8, wherein a suture runs from the proximal handle, through the knot pusher, through a top portion of the bag, and terminates with a knot at the knot pusher.

10. The surgical instrument of claim 9, wherein the suture is configured to close the bag upon pulling the suture at the proximal handle in the retracted position.

11. The surgical instrument of claim 9, wherein the knot pusher is configured to be retained at a distal end of the outer sheath in the retracted position.

12. The surgical instrument of claim 2, wherein the first collapsible arm and the second collapsible arm may be articulated at the articulated joint.

13. The surgical instrument of claim 2, wherein the first collapsible arm and the second collapsible arm may be rotated.

14. A surgical instrument, comprising:

a hybrid shaft having a proximal end and a distal end, wherein the hybrid shaft extends from a proximal handle to the distal end of the surgical instrument, wherein the distal end is flexible, and wherein the proximal end is rigid;

at least one collaspsible arm located at the distal end of the hybrid shaft;

a bag having an open end and a closed end, wherein the bag is configured to be retained upon the at least one collaspsible arm;

a knot pusher located at the distal end of the hybrid shaft;

an articulating joint, wherein the articulating joint connects the at least one collapsible arm to the hybrid shaft; and

an outer sheath extending from a distal handle to the distal end of the surgical instrument.

15. The surgical instrument of claim 14, wherein the outer sheath translates from an unfired position to a fired position upon translation of the distal handle towards the proximal handle, wherein the hybrid shaft, the at least one collapsible arm, the bag, the articulating joint, and the knot pusher are contained within the outer sheath in the unfired position, and wherein the at least one collapsible arm, the bag, the articulating joint, and the knot pusher are removed from containment of the outer sheath in the fired position.

16. The surgical instrument of claim 15, wherein the outer sheath translates from the fired position to a retracted position upon translation of the distal handle from the proximal handle, wherein the at least one collapsible arm, and the articulating joint are contained within the outer sheath in the retracted position.

17. The surgical instrument of claim 16, wherein a suture runs from the proximal handle, through the knot pusher, through a top portion of the bag, and terminates with a knot at the knot pusher.

18. The surgical instrument of claim 17, wherein the suture is configured to close the bag upon pulling the suture at the proximal handle in the retracted position, and wherein the knot pusher is configured to be retained at a distal end of the outer sheath in the retracted position.

19. A method comprising:

providing a surgical instrument, wherein the surgical instrument may comprise a distal handle, an outer sheath, a bag having an open end and a closed end, a hybrid shaft, and at least one collapsible arm, wherein the bag is configured to be retained upon the at least one collapsible arm;

inserting the surgical instrument within a patient through an opening within the patient;

translating the distal handle proximally to deploy the bag and the at least collapsible arm from the outer sheath;

receiving biological materials in the bag;

translating the distal handle distally to return the at least one collapsible arm to the outer sheath;

cinching the bag with the assistance of a knot pusher by pulling a suture at a proximal handle; and

removing the bag containing biological material from the patient.

20. The method of claim 19, further comprising:

sterilizing the surgical instrument; and

storing the surgical instrument in a sterile container.
