Method of closing a wound using a wound closure product
A wound closure system and a method of closing a wound are disclosed. The wound closure system includes a plurality of skin anchors mechanically attached to external skin tissue around a periphery of a wound, a line extending between the skin anchors, the line slidably engaged with each skin anchor, and a biasing member that provides tension on the line to draw all of the skin anchors toward the wound. The method of closing a wound includes the steps of attaching a plurality of skin anchors to external skin around a periphery of a wound, extending a line between the skin anchors around substantially the entire periphery of the wound, and providing tension to the line to draw the skin anchors toward the wound.
1. A method of closing a wound, the method comprising the steps of:
(a) attaching a plurality of skin anchors to external skin tissue around a periphery of a wound;
(b) extending a line between the skin anchors and around substantially the entire periphery of the wound without any portion the line penetrating through the skin tissue;
(c) providing a biasing member that is separate from the line to apply a continuous pulling force on the line to draw all of the skin anchors toward each other, wherein no portion of the biasing member is located inside the periphery of the wound, the biasing member adapted to apply a continuous pulling force on the line to keep the line taut between the skin anchors when the skin anchors move toward each other, wherein the biasing member includes a spring; and
(d) providing a housing that houses the spring, the housing including a spool rotatably coupled to the housing, the spool coupled to the spring and adapted for winding the spring for the application of the continuous pulling force on the line, the housing and the spring including intermating structures adapted for winding the spring, wherein the intermating structures are adapted to slip with respect to each other when the spring has been fully wound to provide an indication that the spring is fully wound.
2. A method according to claim 1 , further comprising attaching at least one of the skin anchors to external skin tissue with a skin-penetrating structure.
3. A method according to claim 1 , wherein the plurality of skin anchors includes at least three or more skin anchors.
4. A method according to claim 1 , wherein the intermating structures include radially arranged indents formed within the housing and a radially outwardly protruding tab of the spring.
5. A method of closing a wound, the method comprising the steps of:
(a) attaching a plurality of skin anchors to external skin tissue around a periphery of a wound;
(b) extending a line between each of the skin anchors without any portion the line penetrating through the skin tissue;
(c) providing a biasing member that is separate from the line to apply a continuous pulling force on the line to draw all of the skin anchors toward each other, wherein no portion of the biasing member is located inside the periphery of the wound, the biasing member adapted to apply a continuous pulling force on the line to keep the line taut between the skin anchors when the skin anchors move toward each other, wherein the biasing member includes a spring; and
(d) providing a housing that houses the spring, the housing including a spool rotatably coupled to the housing, the spool coupled to the spring and adapted for winding the spring for the application of the continuous pulling force on the line, the housing and the spring including intermating structures adapted for winding the spring, wherein the intermating structures are adapted to slip with respect to each other when the spring has been fully wound to provide an indication that the spring is fully wound.
6. A method according to claim 5 , further comprising extending the line around substantially the entire periphery of the wound.
7. A method according to claim 5 , further comprising attaching at least one of the skin anchors to external skin tissue with a skin-penetrating structure.
8. A method according to claim 5 , wherein the plurality of skin anchors includes at least three or more skin anchors.
9. A method according to claim 5 , wherein the intermating structures include radially arranged indents formed within the housing and a radially outwardly protruding tab of the spring.
10. A method according to claim 5 , further comprising slidably engaging each of the skin anchors with the line.
11. A method of closing a wound, the method comprising the steps of:
(a) attaching a plurality of skin anchors to external skin tissue around a periphery of a wound;
(b) extending a line between each of the skin anchors without any portion the line penetrating through the skin tissue, wherein the line is extended between the skin anchors in a shoe-lace configuration with the line including a portion that crosses the wound at least twice;
(c) providing a biasing member that is separate from the line to apply a continuous pulling force on the line to draw all of the skin anchors toward each other, wherein no portion of the biasing member is located inside the periphery of the wound, the biasing member adapted to apply a continuous pulling force on the line to keep the line taut between the skin anchors when the skin anchors move toward each other, wherein the biasing member includes a spring; and
(d) providing a housing that houses the spring, the housing including a spool rotatably coupled to the housing, the spool coupled to the spring and adapted for winding the spring for the application of the continuous pulling force on the line, the housing and the spring including intermating structures adapted for winding the spring, wherein the intermating structures are adapted to slip with respect to each other when the spring has been fully wound to provide an indication that the spring is fully wound.
12. A method according to claim 11 , further comprising slidably engaging each of the skin anchors with the line.
13. A method according to claim 11 , further comprising attaching at least one of the skin anchors to external skin tissue with a skin-penetrating structure.
14. A method according to claim 11 , wherein the plurality of skin anchors includes at least three or more skin anchors.
15. A method according to claim 11 , wherein the intermating structures include radially arranged indents formed within the housing and a radially outwardly protruding tab of the spring.
16. A method of closing a wound, the method comprising the steps of:
(a) attaching at least three or more skin anchors to external skin tissue around a periphery of a wound;
(b) extending a line between the skin anchors and around substantially the entire periphery of the wound without any portion the line penetrating through the skin tissue;
(c) providing a spring to apply a continuous pulling force on the line to draw all of the skin anchors toward each other, the spring adapted to apply a continuous pulling force on the line to keep the line taut between the skin anchors when the skin anchors move toward each other; and
(d) providing a housing that houses the spring, the housing including a spool rotatably coupled to the housing, the spool coupled to the spring and adapted for winding the spring for the application of the continuous pulling force on the line, the housing and the spring including intermating structures adapted for winding the spring, wherein the intermating structures are adapted to slip with respect to each other when the spring has been fully wound to provide an indication that the spring is fully wound.
17. A method according to claim 16 , further comprising attaching at least one of the skin anchors to external skin tissue with a skin-penetrating structure.
18. A method according to claim 16 , wherein the intermating structures include radially arranged indents formed within the housing and a radially outwardly protruding tab of the spring.
