Knotless endostitch suture retainer
View Patent ↗A suture retainer is provided for supplying a surgical needle and an associated length of relatively stiff suture material to a surgical suturing apparatus. The suture retainer generally includes a body portion defining a suture tray and a loading unit positioned on the body portion. The loading unit is provided to retain a surgical needle in a position to be grasped by a surgical suturing apparatus. The suture tray retains the length of relatively stiff suture in a manner which prevents the relatively stiff suture from bending or otherwise being deformed.
1. A suture retainer comprising:
a linear suture material;
a surgical needle affixed to the linear suture material such that the linear suture material extends distally from the surgical needle;
an elongate body portion defining at least one suture tray configured and dimensioned to securely support the linear suture material; and
a loading unit secured to the elongate body portion such that the loading unit is fixed against rotation relative to the elongate body portion, the loading unit including a needle support member configured and dimensioned to support the surgical needle, the needle support member coaxially arranged with the elongate body portion, the loading unit defining a recess configured to receive an elongate tubular member of a surgical suturing apparatus, the recess disposed proximal of the needle support member, the loading unit including opposing side tabs configured to align the elongate tubular member of the surgical suturing apparatus with the linear suture material, wherein at least a portion of the linear suture material supported on the loading unit is aligned with at least a portion of the linear suture material supported on the at least one suture tray.
2. The suture retainer as recited in claim 1 , wherein the loading unit is located proximal to the at least one suture tray.
3. The suture retainer as recited in claim 2 , wherein the elongate body portion includes a distal wall, a proximal wall, and side walls extending between the distal and proximal walls.
4. The suture retainer as recited in claim 3 , wherein the proximal wall includes a gap for passage of a portion of the linear suture material between the loading unit and the at least one suture tray.
5. The suture retainer as recited in claim 3 , further comprising a retainer block positioned within the at least one suture tray, the retainer block releasably securing a portion of the linear suture material within the at least one suture tray.
6. The suture retainer as recited in claim 5 , wherein the retainer block includes a slit to frictionally receive the linear suture material.
7. The suture retainer as recited in claim 5 , wherein the retainer block is formed from a resilient material.
8. The suture retainer as recited in claim 7 , wherein the retainer block is formed from a foam material.
9. The suture retainer as recited in claim 7 , wherein the retainer block is formed from a rubber material.
10. The suture retainer as recited in claim 1 , wherein the elongate body portion includes a first side and a second side, each of the first and second sides including a suture tray and a loading unit.
11. The suture retainer as recited in claim 1 , wherein the loading unit is in communication with the at least one suture tray.
12. The suture retainer as recited in claim 1 , wherein the surgical needle is oriented substantially orthogonal to an orientation of the linear suture material when the linear suture material is supported on the at least one suture tray.
13. The suture retainer as recited in claim 1 , wherein the linear suture material is linear along an entire length thereof.
