Abstract

An organ fixing equipment includes a securing part formed by bundling a suturing thread into a bar, and a fixing part composed of the suturing thread forming the securing part and a continuous suturing thread. By pulling the fixing part relative to the securing part with a force of not less than a predetermined magnitude, the suturing thread forming the securing part can be unraveled. A set of organ fixing equipment is provided with an insertion equipment, for inserting the organ fixing equipment and taking-out equipment for taking out the organ fixing equipment from the patient body.

Claims

1. An organ fixing device, comprising

a suture thread having a first end portion, a second end portion and an intermediate portion connecting the first end portion to the second end portion, the first end portion defining a pulling part, the intermediate portion and the second end portion defining a securing part,

wherein the intermediate portion of the suture thread comprises a plurality of folded segments and the second end portion of the suture thread comprises a plurality of coiled segments, and wherein each of the coiled segments is disposed around the plurality of folded segments,

wherein the plurality of coiled segments define a coil portion having opposite longitudinal ends, the pulling part being connected to the intermediate portion of the suture thread at a location intermediate the opposite longitudinal ends of the coil portion.

2. The device of claim 1, wherein the securing part comprising the intermediate and second end portions of the suture thread defines a bar having a longitudinal center, and wherein the location where the pulling part is connected to the intermediate portion of the suture thread is at the longitudinal center of the bar.

3. The device of claim 1, wherein the location where the pulling part is connected to the intermediate portion of the suture thread is between adjacent coiled segments of the plurality of coiled segments.

4. The device of claim 1, wherein the suture thread is T-shaped, the pulling part extending perpendicularly from the securing part.

5. The device of claim 1, wherein the securing part is configured such that when the pulling part is pulled relative to the securing part with at least a predetermined force, the folded segments being sequentially withdrawn from the coil portion so that the securing part unravels.

6. The device of claim 1, in combination with insertion equipment for use in inserting the securing part of the suture thread in a stomach of a subject, the insertion equipment including a piercing needle configured for piercing abdomen and stomach walls of the subject, the piercing needle defining a passage configured for receiving the securing part of the suture thread to facilitate delivery of the securing part of the suture thread through the abdomen and stomach walls of the subject and into the stomach of the subject.

7. The device of claim 6, wherein the insertion equipment further includes a protrusion portion having a cylindrical member configured for reception in the passage of the piercing needle to facilitate delivery of the securing part of the suture thread into the stomach of the subject through the passage of the piercing needle.

8. The device of claim 6, in further combination with taking-out equipment for removing the organ fixing device from the subject, the taking-out equipment including a cylindrical portion having a helical groove for receiving the suture thread of the organ fixing device.
