The present disclosure relates to tissue specimen retrieval from an internal body cavity and, more particularly, to tissue specimen retrieval devices and methods to facilitate retrieval of a tissue specimen from an internal body cavity.
In minimally-invasive surgical procedures, operations are carried out within an internal body cavity through small entrance openings in the body. The entrance openings may be natural passageways of the body or may be surgically created, for example, by making a small incision into which an access device is inserted.
Minimally-invasive surgical procedures may be used for partial or total retrieval of a tissue specimen from an internal body cavity. However, the restricted access provided by minimally-invasive openings (natural passageways and/or surgically created openings) presents challenges with respect to maneuverability and visualization. The restricted access also presents challenges when the tissue specimen is required to be removed. As such, a tissue specimen that is deemed too large for intact retrieval may be broken down into a plurality of smaller pieces to facilitate retrieval from the internal body cavity.
During such minimally-invasive surgical procedures, it is common that a cyst, tumor, or other affected tissue specimen is required to be removed. In these and other procedures where cancerous tissue is required to be removed, retrieval of the tissue specimen in an enclosed environment is highly desirable to inhibit seeding of cancer cells. Thus, with respect to breaking down large tissue specimens for retrieval through minimally-invasive openings, there is the added challenge of doing so within an enclosed environment.
As used herein, the term “distal” refers to the portion that is described which is further from a user, while the term “proximal” refers to the portion that is being described which is closer to a user. The terms “substantially” and “approximately,” as utilized herein, account for industry-accepted material, manufacturing, measurement, use, and/or environmental tolerances. Further, any or all of the aspects and features described herein, to the extent consistent, may be used in conjunction with any or all of the other aspects and features described herein.
Provided in accordance with aspects of the present disclosure is a tissue specimen retrieval device that includes a first shaft and a second shaft telescopically movable relative to the first shaft. The second shaft supports an end effector assembly at a distal end thereof and is movable relative to the first shaft between a retracted position, wherein the end effector assembly is disposed within the first shaft, and a deployed position, wherein the end effector assembly extends distally from the first shaft in an expanded configuration.
The end effector assembly includes a bag brim having a wire support with first and second ends that operably engage the distal end of the second shaft. The bag brim is transitionable from a first collapsed configuration for disposition within the first shaft to an expanded, substantially circular configuration upon deployment from the first shaft. The wire support includes two or more torsion springs disposed between the first and second ends thereof. The at least two torsion springs cooperate to facilitate automatic expansion of the bag brim to the expanded configuration upon deployment thereof from within the first shaft.
In aspects according to the present disclosure, the two or more torsion springs are spaced at equal distances around the wire support. In other aspects according to the present disclosure, the wire support includes at least three torsion springs disposed therealong configured to facilitate automatic expansion of the bag brim upon deployment from within the first shaft. In still other aspects according to the present disclosure, the bag brim includes a second wire support having first and second ends that operably engage the distal end of the second shaft. The second wire support includes two or more torsion springs disposed between the first and second ends thereof. The two or more torsion springs cooperating to facilitate automatic expansion of the bag brim to the expanded configuration upon deployment thereof from within the first shaft.
In aspects according to the present disclosure, the two or more torsion springs of the first and second wire supports are disposed in substantial registration relative to one another along each respective wire support. In other aspects according to the present disclosure, the two or more torsion springs of the first and second wire supports are held in substantial registration with one another by a rivet. In yet other aspects according to the present disclosure, the bag brim includes a heat shrink tubing that encapsulates the two or more torsion springs and/or the rivet.
In aspects according to the present disclosure, the wire support of the bag brim is made from high yield stainless steel. Other types of materials may also be utilized, e.g., polymers, plastics, shape memory alloys, composite materials, surgical stainless steel, aluminum etc.
In accordance with another aspects of the present disclosure is a tissue specimen retrieval device that includes a first shaft and a second shaft telescopically movable relative to the first shaft. The second shaft supports an end effector assembly at a distal end thereof and is movable relative to the first shaft between a retracted position, wherein the end effector assembly is disposed within the first shaft, and a deployed position, wherein the end effector assembly extends distally from the first shaft in an expanded configuration.
The end effector assembly includes a bag brim having first and second wire supports each including first and second ends that operably engage the distal end of the second shaft. The bag brim is transitionable from a first collapsed configuration for disposition within the first shaft to an expanded configuration upon deployment from the first shaft. The wire supports each include two or more torsion springs disposed between each first and second end thereof. Each respective torsion spring of the two or more torsion springs of each wire support is disposed in substantial registration with the respective torsion spring of the other wire support and cooperates to form a corresponding number of dual torsion springs configured to facilitate automatic expansion of the bag brim to the expanded configuration upon deployment thereof from within the first shaft.
In aspects according to the present disclosure, the dual torsion springs are spaced at equal distances around the bag brim. In other aspects according to the present disclosure, the bag brim includes three or more dual torsion springs disposed therealong configured to facilitate automatic expansion of the bag brim upon deployment from within the first shaft.
In aspects according to the present disclosure, the two or more torsion springs of the first and second wire supports are held in substantial registration with one another by a rivet. In yet other aspects according to the present disclosure, the bag brim includes a heat shrink tubing that encapsulates each dual torsion spring. In still other aspects according to the present disclosure, the wire supports of the bag brim are made from high yield stainless steel. Other types of materials may also be utilized, e.g., polymers, plastics, shape memory alloys, composite materials, surgical stainless steel, aluminum etc.
The above and other aspects and features of the present disclosure will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings wherein like reference numerals identify similar or identical elements.
