## Abstract

A surgical suture is provided, which includes a hollow cone and a thread. The cone has a front opening and a rear opening at two opposite ends thereof, wherein a diameter of the front opening is smaller than a diameter of the rear opening. The thread passes through the cone, and integrally includes at least two protrusions thereon, which are separated from each other by a certain distance. Each of the protrusions has a width in a radial direction of the thread, wherein the width is greater than a diameter of the thread, and is smaller than the diameter of the rear opening whereby, with the integrally provided protrusions, the cones can be located on the corresponding positions of the thread.

## Claims

### Claim 1

A surgical suture, comprising:
a hollow cone having a front opening and a rear opening at two opposite ends thereof, wherein a diameter of the front opening is smaller than a diameter of the rear opening;
a thread passing through the front opening and the rear opening of the cone, wherein the thread integrally comprises at least two protrusions thereon, and the protrusions are separated from each other by a certain distance; each of the protrusions having a width in a radial direction of the thread, wherein the width is greater than a diameter of the thread, and is smaller than the diameter of the rear opening.

### Claim 2 (depends on 1)

The surgical suture of claim 1, wherein the protrusions are made by extruding, compressing, or punching the thread.

### Claim 3 (depends on 2)

The surgical suture of claim 2, wherein each of the protrusions has two side portions at two opposite sides of the protrusion.

### Claim 4 (depends on 1)

The surgical suture of claim 1, satisfying: 1.5D≦W≦8D;
where D is the diameter of the thread, and W is the width of each of the protrusions.

### Claim 5 (depends on 4)

The surgical suture of claim 4, satisfying:
W=3D.

### Claim 6 (depends on 1)

The surgical suture of claim 1, wherein the diameter of the front opening is between 0.2 mm to 0.4 mm; the diameter of the rear opening is between 0.5 mm to 2 mm

### Claim 7 (depends on 1)

The surgical suture of claim 1, wherein either or both of the thread and the cone are made of a biodegradable material.

### Claim 8 (depends on 1)

The surgical suture of claim 1, satisfying:
0.2 mm≦D≦1 mm;
where D is the diameter of the thread.

### Claim 9 (depends on 1)

The surgical suture of claim 1, wherein the cone has a first section and a second section, and both of which have an axis; wherein the surgical suture satisfies:
m1≦m2;
where m1 is a slope of the outer surface of the first section relative to the axis, and m2 is a slope of the outer surface of the second section relative to the axis.

### Claim 10 (depends on 1)

The surgical suture of claim 1, further comprising a plurality of wings provided on an outer surface of the cone.
