## Abstract

A retractor for video-assisted thoracoscopic surgery. The retractor includes a core provided with a first bent portion, a second bent portion vertically extending from the first bent portion, a third bent portion horizontally extending from the second bent portion to correspond to the first bent portion, the core having an insert core part on one side thereof and a hook core part on the other side, a silicon body configured to encapsulate a circumference of the core, a first hook part extending from one side of the silicon body to encapsulate the insert core part of the core, and a second hook part extending from the other side of the silicon body to encapsulate the hook core part of the core.

## Claims

### Claim 1

A retractor for video-assisted thoracoscopic surgery, the retractor comprising:
a core provided with a first bent portion, a second bent portion vertically extending from the first bent portion, a third bent portion horizontally extending from the second bent portion to correspond to the first bent portion, the core having an insert core part on one side thereof and a hook core part on the other side;
a silicon body configured to encapsulate a circumference of the core;
a first hook part extending from one side of the silicon body to encapsulate the insert core part of the core; and
a second hook part extending from the other side of the silicon body to encapsulate the hook core part of the core,
wherein the first hook part comprises:
first and second arc-shaped portions respectively extending from the one side of the silicon body to symmetrical to each other, wherein each of the first and second arc-shaped portions extends in a tapered shape to allow the first hook part to be easily hooked on an area for surgery; and
a third arc-shaped portion that connects the first arc-shaped portion to the second arc-shaped portion,
wherein the second hook part comprises:
fourth and fifth arc-shaped portions respectively extending from the other side of the silicon body to symmetrical to each other, wherein each of the fourth and fifth arc-shaped portions extends in a tapered shape to allow the second hook part to be easily hooked on an area for surgery; and
a first horizontal extending portion that horizontally extends from the fourth arc-shaped portion;
a second horizontal extending portion that horizontally extends from the fifth arc-shaped portion to correspond to the first horizontal extending portion; and
a connecting portion that connects the first horizontal extending portion to the second horizontal extending portion.

### Claim 2 (depends on 1)

The retractor of claim 1, wherein the core encapsulated by the silicon body further comprises a fourth bent portion that vertically connects the first bent portion to the third bent portion, and
the core has a ‘’ shape.

### Claim 3 (depends on 1)

The retractor of claim 1, wherein the silicon body has a length of about 33 cm, and the first hook part has a length of about 1.2 cm, and the second hook part has a length of about 5.5 cm so that the area for surgery is easily hooked and pulled, and movement of the retractor is not interfered in a narrow space for surgery.

### Claim 4 (depends on 1)

The retractor of claim 1, wherein the core has at least one stepped portion on each of both sides thereof.

### Claim 5 (depends on 1)

The retractor of claim 1, wherein the silicon body further comprises a recessed portion having a diameter that is less than that thereof in one side thereof.
