Integrated closure device
View Patent ↗A novel integrated wound closure device for laparoscopy having an elongated body with a distal end and proximal end able to-use suture for closing surgical port wounds comprising a single sequential proximal activation means able to operate multiple internal systems sequentially such as: a distal anchoring system, a self-contained tissue piercing system, a suture staging means to position suture suitable for capture at a target zone, and a suture capturing system to capture and retract suture into said piercing system with all system functions configured internally of said elongated body which can be reused multiple times per patient.
1 . An integrated closure device suitable for closing laparoscopic wounds able to route and retain suture comprising:
an elongated body having a proximal end and a distal end with distal pivoting members, said distal pivoting members comprising suture pathways configured to stage suture;
a plurality of hollow needles;
a single proximal sequential activation means operating at least three functions, said single proximal sequential activation means comprising a rotatable selector;
wherein said single proximal sequential activation means configured to operate by a repeatable movement comprising an initial movement and return movement;
wherein said rotatable selector configured to perform index rotation by incrementally indexing said repeatable movement to align with a function of said at least three functions;
wherein an index rotation amount is a circle divided by the number of functions;
wherein said elongated body having at least one inner channel guide for at least one needle of said plurality of hollow needles;
wherein said distal pivoting members are normally in an expanded configuration;
wherein a first of said initial movement is configured to contract said distal pivoting members to enter a patient wound;
wherein a first of said return movement is configured to expand said distal pivoting members to prevent accidental wound exit;
wherein a beginning half of a second of said initial movement is configured to extend at least one of said plurality of hollow needles, and wherein a returning half of said second of said initial movement is configured to extend a suture capture hook within said at least one needle of said plurality of hollow needles to capture suture in succession;
wherein a beginning half of a second of said return movement is configured to retract said captured suture into said at least one needle of said plurality of hollow needles, and wherein a remaining half of said second of said return movement is configured to then retract said at least one needle of said plurality of hollow needles in succession;
wherein a third of said initial movement is configured to contract said distal pivoting members;
wherein a third of said return movement is configured to return said distal pivoting members to its normally expanded configuration again; and
wherein said integrated closure device is configured to be withdrawn from a wound to allow released suture to be tied by a surgeon.
2 . An integrated closure device as in claim 1 whereby said suture pathways allow near zero suture length change whether said distal pivoting members are expanded or contracted.
3 . An integrated closure device as in claim 1 whereby a pinch ring is configured to retain suture ends of said suture in tension by friction.
4 . An integrated closure device as in claim 1 whereby said integrated closure device can be re-used multiple times per patient.
5 . An integrated closure device as in claim 1 whereby said plurality of hollow needles are each composed of a rigid sharp distal end and a flexible elongated member at their respective proximal end.
