Perlove medical intelligent orthopedic robot has been assisted to carry out nearly one hundred surgeries, the main application procedures include percutaneous vertebral balloon dilatation plasty (PKP), lumbar vertebral fracture percutaneous pedicle internal fixation, lumbar spine posterior incision and internal fixation + interbody fusion, sacral tumor puncture biopsy, bone tissue biopsy, percutaneous vertebral body reinforcement + percutaneous vertebral body fixation, and so on. Perlove Intelligent Orthopaedic Robot has become a close partner of spine surgeons and a strong assistant for minimally invasive orthopaedic surgery.

Case sharing: Lumbar posterior internal fixation + interbody fusion

Age】70 years old

Gender] Female

Preoperative diagnosis] Lumbar spinal stenosis

Pre-operative X-ray and nuclear magnetic examination showed that the patient’s spine had multi-segmental lesions, lateral curvature and rotation, deviation from the conventional anatomical position, and vertebral body hyperplasia, which made the surgery more difficult and required high precision in the operation. The consultation team decided to perform a robot-assisted “posterior lumbar internal fixation + interbody fusion” surgery after a comprehensive argumentation, taking into account the patient’s objective physical condition.

The one-time precise planning of 14 screws was performed by using Perlove’s flatbed 3D C-arm to scan the patient, obtain intraoperative 3D images and transmit them to the intelligent orthopedic robot workstation. Based on the 3D image data, the surgeon completed the positioning planning of 14 screws in one go using the surgical planning software.

Compared with the traditional surgery, it is tedious to manually enter and position the screws several times. The intelligent orthopedic robot can realize one-time planning of multiple screw paths, saving planning and positioning time, simplifying the surgical operation steps, and significantly improving the efficiency of nail placement.

After the robot guides the precise placement of the guide pin to complete the positioning of the surgical access, the robotic arm maintains a stable access direction guidance, the doctor only needs to focus on drilling and nailing operations, the guide pin enters more stably, and the execution accuracy is sub-millimeter level.

In traditional surgery, repeated insertion of the needle more than ten times is a great challenge to the doctor’s skills, experience and hand stability. Robot-guided needle placement guarantees accuracy and repeatability. The robot can repeat the operation precisely, reducing individual variability and experience dependence in surgical operations.

The C-arm was used to verify the accuracy of the guided needle path, and the appropriate screws were selected for implantation based on the simulated pedicle screw sizes designed by navigation planning. During the operation, it was verified that all 14 screws were located in the pedicle, which was in line with the ideal nail path designed before the operation, and the screws were of appropriate sizes.

■ The combination of Perlove’s self-developed 3D C-arm and intelligent orthopedic robots enables intraoperative 3D imaging and precise positioning, which makes the original high-difficulty, high-risk and complex spine surgeries more process-oriented and standardized, and shortens the learning curve for doctors.

Robot-assisted, helping the surgery to be more minimally invasive and precise, with less trauma to the patient, less bleeding, and a better prognosis for the patient.

Traditional percutaneous spinal nailing, intraoperative X-ray fluoroscopy is often required several times,Perlove Medical Intelligent Orthopaedic Robot can accurately locate the nails through three-dimensional imaging, which allows for one-time planning and precise nailing, reducing the time of radiation exposure of healthcare workers and making the surgery safer.
