Abstract

The present invention provides an organ fixture having a rod shaped anchoring portion formed by bundling a suturing thread, and a fixing portion made of a suturing thread continuous with the suturing thread of the anchoring portion. By pulling the fixing portion with respect to the anchoring portion with a force larger than a prescribed level, the suturing thread forming the anchoring portion can be loosened. Additionally, the invention provides a type of organ fixture set which pierces and is inserted into the body of the patient while a portion of an anchoring portion and a fixing portion of the organ fixture is accommodated in it, and it can be pulled from the body of the patient while the anchoring portion is left within the stomach wall. Further, the organ fixture set has a unit for removing the organ fixture from the body of the patient.

Claims

1. A surgical fastener comprising an elongate anchoring portion (11) and a fixing portion (12) extending from the anchoring portion wherein the fixing portion is a suturing thread and the anchoring portion (11) is composed of a suture thread bundling (13, 14), the suture thread of the fixing portion (12) being continuous with the suture thread of the anchoring portion (11).

2. The fastener according to claim 1 wherein said anchoring portion (11) can be loosened by pulling said fixing portion (12) with respect to said anchoring portion with a force larger than a prescribed level.

3. The fastener according to claim 1 or claim 2 wherein said anchoring portion (11) comprises a core (13) of folded suturing thread and a winding portion (14) of suturing thread wrapped around said core portion (13).

4. The fastener according to claim 1 wherein the anchoring portion (11) includes an adhesive made of a bioabsorbable material.

5. The fastener according to claim 4 wherein said anchoring portion (11) comprises a core (13) of folded suturing thread and a winding portion (14) of suturing thread wrapped around said core portion (13).

6. The fastener according to any preceding claim wherein the anchoring portion (11) is substantially rod-shaped and the fixing portion (12) extends substantially perpendicularly from a central region of the anchoring portion (11).

7. The fastener according to any preceding claim wherein the fixing portion (12) of the fastener is secured to a fixing portion (12) of another such fastener.

8. The fastener according to any preceding claim wherein the suturing thread of the anchoring portion (11) is made of a different material to the suturing thread of the fixing portion (12).

9. The fastener according to claim 8 wherein the suturing thread of the anchoring portion (11) is made of a bioabsorbable material.

10. A sterile surgical kit comprising one or more surgical fasteners according to any one of claims 1-9 and an inserting unit (20, 40).

11. The kit according to claim 10 wherein said inserting unit (20) comprises a hollow piercing needle (21) and an extruder (22) within said needle.

12. The kit according to claim 10 wherein said inserting unit (40) comprises a needle element having a hollow tip portion (45) and wherein the hollow tip portion has a side wall incorporating a slot.

13. A removing unit (30) for removing a surgical fastener according to any one of claims 1-9 inserted in a patient, the removing unit (30) comprising a grooved needle portion (32).

14. The removing unit according to claim 13 wherein the grooved needle portion (32) comprises a distal portion and a proximal portion the distal portion having on an outer surface a substantially spiral groove (34a) and the proximal portion having on an outer surface a substantially linear groove (34b) extending in an axial direction of the needle portion (32).

15. A method of securing a hollow organ of a patient to a skin side wall portion comprising the steps of:

(a) inserting an insertion device carrying a surgical fixture according to any one of claims 1-7 through a patient'"'"'s skin and into said hollow organ,

(b) deploying said surgical fixture,

(c) removing said insertion device leaving said surgical fixture in said patient,

(d) repeating steps (a)-(c) at least once, and

(e) securing together fixing portions of a plurality of surgical fixtures inserted into said patient.

16. The method according to claim 15 wherein the method of securing is a method for securing a patient'"'"'s stomach wall to the patient'"'"'s abdominal wall.

17. The method according to claim 14 wherein following the securing of the patient'"'"'s stomach wall to the patient'"'"'s abdominal wall, a gastrostomy tube is inserted in to the patient'"'"'s stomach.

18. A method of removing a surgical fixture according to any one of claims 1-9 comprising the steps of:

(a) inserting a removal device into a patient such that a fixing portion of said surgical fixture enters a grooved portion of said removal device,

(b) applying tension to said fixing portion such that an anchoring portion of said surgical fixture becomes loosened, and

(c) continuing the application of tension to said fixing portion until said surgical fixture is fully removed from said patient, and

(d) removing said removal device from said patient.

19. An organ fixture (10) formed by using suturing thread characterized by an anchoring portion (11) and a fixing portion (12) extending from and axial to the anchoring portion (11) through a hole (29) in a patient.
