## Abstract

A machine, and method of using, constructed and configured for automatic continuous suturing for reduced or minimized scarring and reduced suturing time, including a helical shaped needle, a hook, and a holding arm. The needle is used to provide for substantially planar stitching adjoining edges side by side. The hook is used to manipulate the stitching in automatic coordination with the needle so as to allow for continuous stitching. The holding arm is used in automatic coordination with the hook. The coordination and synchronization of these components provide for continuous planar stitches which adjoin edges side by side.

## Claims

### Claim 1

A device for making continuous suture stitches comprising:
a suture thread supply;
a helical shaped needle rotationally movable between a first and second position and positioned for introducing the suture thread supply into a first edge and a second edge;
a hook positioned parallel to the needle shaft and configured for translational movement between a retracted and extended position for receiving and releasing the suture thread supply in automatic coordination with the needle; and
a catcher positioned perpendicular to the hook and comprising a push and a catch arm, the push and the catch arm each configured for translational movement for pushing and catching the suture thread supply in automatic coordination with the hook;
thereby providing the device for making continuous suture stitches for adjoining the first and second edge in an edge-to-edge interface.

### Claim 2 (depends on 1)

The device of claim 1 wherein the needle and the hook are adjustable to be configured in an angled position relative to a surface being stitched.

### Claim 3 (depends on 1)

The device of claim 1 wherein the device further comprises a cutting mechanism for cutting the suture thread supply.

### Claim 4 (depends on 1)

The device of claim 1 wherein the device further comprises a guard to maintain the edge-to-edge interface.

### Claim 5

A device for continuous surgical suturing comprising:
a spiral shaped needle constructed and configured for receiving a suture thread;
a hook constructed and configured for translational movement in automatic cooperation with the needle for manipulating the suture thread; and
a catcher comprising a push and a catch arm in automatic coordination with the hook;
thereby providing the device for continuous surgical suturing with minimal scarring.

### Claim 6 (depends on 5)

The device of claim 5 wherein the needle and the hook are adjustable to be configured in an angled position relative to a surface being stitched.

### Claim 7 (depends on 5)

The device of claim 5 wherein the device further comprises a cutting mechanism for cutting the suture thread supply.

### Claim 8

A device for continuous subcuticular surgical suturing comprising:
a helico-spiral shaped needle having a pitch, the needle constructed and configured for receiving a suture thread;
a hook constructed and configured for automatic coordination with the needle for manipulating a suture thread;
an offset footing positioned for providing an offset between a first and second edge of a cut;
wherein the offset is equal to the pitch of the needle; and
a catcher comprising a push and a catch arm in automatic coordination with the hook;
thereby providing the device for continuous subcuticular surgical suturing with minimal scarring.

### Claim 9 (depends on 8)

The device of claim 8 wherein the offset footing further comprises a roller.

### Claim 10 (depends on 9)

The device of claim 9 wherein the roller is in automatic coordination with the needle.

### Claim 11 (depends on 8)

The device of claim 8 wherein the needle and the hook are adjustable to be configured in an angled position relative to a surface being stitched.

### Claim 12 (depends on 8)

The device of claim 8 wherein the device further comprises a cutting mechanism for cutting the suture thread supply.

### Claim 13 (depends on 8)

The device of claim 8 wherein the device further comprises a guard to maintain an interface between the first and the second edge of the cut.
