ROBODOC Surgical System

Product Composition


High-performance computer with pre-planning

1. Surgical plan

Only the bones are excerpted in the CT image and shown in 3D for checking the preoperative bone state of patients and accurate surgical planning.

SMG (Surface Model Generation) is the technology which recomposes only the bone surface of patient’s CT image and converts it into a 3D image. The doctor can not only provide an in-depth diagnosis with the 3D image as of looking at the affected area in person but also perform personalized surgical planning and virtual surgery.

2. Personalized surgery

The doctor can select the artificial joint personalized for a different bone size of each patient, and insert it virtually to check the optimal size.

The doctor can check the insertion position of the artificial joint which considered the bone state of each patient and the cutting area of the damaged bone via ORTHODOC beforehand.
Because it also shows 3-sided views including the front, sides, and cross-section of the surgical area, it is also possible to have a more detailed, accurate, and integrated surgical plan.

3. Virtual surgery

It is possible to perform preoperative simulated surgery to review the alignment, angle, and shape of the leg axis and check if the surgical plan is well made.

Virtual surgery is a process to review the surgical plan finally and check the surgical result in advance in order to increase surgical completeness. The planned simulation provides a review of the surgical plan and a prediction of the patient’s postoperative state.


Fully automatic surgical robot for bone cutting with a milling cutter

1. It precisely performs the plan made in ORTHODOC to the patients.

After performing fixation of the patient’s leg and registration of the position, and completing verification of the surgical position, plan, and range, the robot cuts the bone precisely where the artificial joint will be inserted. Accordingly, it reduces the unnecessary bone cutting and surgical errors resulting in fewer side effects and lower possibilities of reoperation.

2. The use of milling cutter decreases the impact on the bone and postoperative pains.

The surgical robot is designed to cut the bone according to the plan made by the doctor. For that reason, it not only provides the consistent and accurate surgical results but also precise surgery with a personalized plan.
The milling cutter reduces the impact on the patient’s weak bone, and thus cuts down the occurrence ratio of side effects such as fractures.

3. The dual safety system enhances surgical safety.

BMM (Bone Motion Monitor) function can detect the patient’s intraoperative slight movement. Once the movement is detected, the robot stops the motion and prevents errors caused by the patient’s movement.

There is a built-in computer that plays the brain of ROBODOC.
The built-in Real Time Monitor shows surgical condition of the area to be cut, cut, and being cut in real time.
