Apparatus and method for manufacturing surgical guide, and surgical guide
Provided is an apparatus for manufacturing a surgical guide that guides a cutting line formed to surround a tumor of an organ, the apparatus including: an organ modeling unit configured to model a 3-dimensional (3D) image of the organ, based on an image of a patient captured by an external imaging apparatus; a cutting line determining unit configured to determine, in the 3D image of the organ, the cutting line to correspond to a location of the tumor and an entry angle of a surgical instrument to the cutting line; and a guide manufacturing unit configured to manufacture a surgical guide that guides the surgical instrument to the cutting line in a slanting manner corresponding to the entry angle, based on the 3D image of the organ.
1. A surgical guide that is configured to be mounted on an organ of a patient during a medical operation to guide a surgical instrument to a cutting line surrounding a tumor of the organ, the surgical guide comprising:
a surgical guide body configured to be mounted on the organ and to at least partially enclose a part of the organ, thereby fixing the organ using the surgical guide body; and
a guide hole disposed on the surgical guide body, wherein the guide hole corresponds to a location of the tumor, an inner wall of the guide hole defines and exposes the cutting line surrounding the tumor, and a first portion of the inner wall of the guide hole is formed to have a first preset angle corresponding to a first entry angle of the surgical instrument for cutting the tumor, and
wherein the surgical guide body, the guide hole, and the cutting line defined by the guide hole are modelled based on a 3-dimensional (3D) medical image of the organ including the tumor of the patient.
2. The surgical guide of claim 1 , wherein the surgical guide body forms a space where the one part of the organ is configured to be inserted.
3. The surgical guide of claim 1 , wherein the organ is a kidney and the surgical guide body has a preset curvature configured to at least partially enclose a part of the kidney.
4. The surgical guide of claim 1 , wherein the surgical guide body comprises a mesh structure.
5. The surgical guide of claim 1 , wherein the surgical guide body comprises a shape memory alloy restored to a specified shape in response to a temperature or electricity.
6. The surgical guide of claim 1 , wherein a second portion of the inner wall of the guide hole is formed to have a second preset angle corresponding to a second entry angle of the surgical instrument for cutting the tumor, and the first preset angle of the first portion of the inner wall is different from the second preset angle of the second portion of the inner wall.
7. The surgical guide of claim 1 , wherein the surgical guide body comprises:
a support portion disposed adjacent the guide hole and covering a portion of the part of the organ enclosed by the surgical guide body; and
a connecting portion whose ends are respectively connected to edges of the support portion and other ends are selectively attached to each other.
