Abstract

Provided is a surgical robot for changing a position of surgical equipment capable of selectively using the surgical equipment appropriate for affected areas by rotating the surgical equipment instead of changing a position of the surgical equipment by detachment, by integrating a plurality of flexible shafts having a surgical equipment attached to a leading end thereof to configure a single shaft assembly and allowing each flexible shaft to perform translation, rotation, and bending motions and rotating the shaft assembly. According to the embodiment of the present invention, the surgical robot for changing a position of surgical equipment includes: a housing 200 coupled with a rear end of the frame fixing part 100 ; a curved frame 300 coupled with a leading end of the frame fixing part 100 ; and a shaft assembly 400 , wherein the shaft assembly 400 penetrates through the curved frame 300 within the housing 200 to be exposed to a leading end of the curved frame 300 and rotates within the curved frame 300.

First claim

The invention claimed is:

1. A surgical robot for changing a position of surgical equipment, comprising:
a frame fixing part;
a housing coupled with a rear end of the frame fixing part;
a curved frame coupled with a leading end of the frame fixing part; and
a shaft assembly,
wherein the shaft assembly passes through the curved frame to be exposed to a leading end of the curved frame, continues into the housing, and rotates within the curved frame,
wherein the shaft assembly includes a plurality of flexible shafts having surgical equipments, and each of the surgical equipments is attached to a leading end of each of the plurality of flexible shafts,
wherein the curved frame includes a fixed frame coupled with the leading end of the frame fixing part, and a rotating frame rotatably mounted at a leading end of the fixed frame, and
wherein the rotating frame is formed with a channel through which the plurality of flexible shafts slides.

2. The surgical robot of claim 1 , wherein the housing includes a housing rear end and a housing front end coupled with the shaft assembly, and the housing front end rotates with respect to the housing rear end.

3. The surgical robot of 1 , wherein a leading end of the housing is provided with a rotating plate rotating by a rotating driving part, and the rotating plate is coupled with a shaft holder into which the plurality of flexible shafts is inserted.

4. The surgical robot of claim 3 , wherein the shaft holder is detachably coupled with a moving member within the housing to advance and retreat the plurality of flexible shafts.

5. The surgical robot of claim 4 , wherein each surface on which the shaft holder and the moving member coupled with each other is formed with power terminals and control terminals.

6. The surgical robot of claim 1 , wherein the fixed frame includes a straight part fixed to the frame fixing part and a curved part connected to a leading end of the straight part, and the straight part and the curved part are a rigid body.

7. The surgical robot of claim 6 , wherein the curved part has one or more rotating links embedded therein, the one or more rotating links being formed with through holes through which the plurality of flexible shafts penetrates, and the one or more rotating links rotate together when the plurality of flexible shafts rotates.

8. The surgical robot of claim 7 , wherein the straight part has a spacer maintaining an interval between the plurality of flexible shafts embedded therein and the spacer rotates together when the plurality of flexible shafts rotates.

9. The surgical robot of claim 8 , wherein the rotating frame, the one or more rotating links, and the spacer are connected to each other by a member elastically deformed in a longitudinal direction.

10. The surgical robot of claim 1 , wherein the rotating frame is coupled with a fixture configured to include a fixed plate and a tension wire the fixed plate.

11. The surgical robot of claim 1 , wherein the plurality of flexible shafts includes a flexible shaft having forceps attached to a leading end thereof and a flexible shaft having scissors attached to a leading end thereof.

12. The surgical robot of claim 11 , wherein the plurality of flexible shafts further includes a flexible shaft having accessory devices attached to a leading end thereof.
