Perlove Intelligent Orthopedic Robot-Assisted Lumbar Spondyloscopic Fusion Surgery: Precise, Minimally Invasive, and Safe


With the rapid development of social modernization, orthopedic diseases have become the fourth leading cause of death worldwide, posing a serious threat to human health and life. Against this background, the rise of artificial intelligence technology has brought new hope to the orthopedic medical field. Intelligent orthopaedic robots are increasingly used in clinics, which provide efficient and precise solutions for the treatment of orthopaedic diseases through precise surgical planning, accurate positioning of prosthesis placement, and assisted operation of the robot arm, which significantly improves the treatment results of patients.

The development process of lumbar fusion surgery

The development process of lumbar spine fusion surgery reflects the progress of medical technology. Traditional open surgery, performed through a large incision, is intuitive and easy to operate, but it can cause damage to the surrounding muscles and structures, and postoperative recovery time is longer; minimally invasive surgery (e.g., MIS-TLIF, etc.), through the field of view of the microscope or micro-endoscopy for intervertebral disc processing and fusion placement, the incision is smaller than the traditional surgery, but it still belongs to the semi-open surgical method.

In recent years, endoscopic technology has been gradually introduced into the field of intervertebral fusion, and minimally invasive operation under direct vision has brought a new direction to spinal surgery. The microscopic fusion technique is a minimally invasive surgery that builds on the development of the intervertebral foramenoscopy technique. The surgeon completes nerve decompression, disc treatment and fusion device placement within an incision of about 2cm, and then percutaneously places pedicle screws for fixation. This type of surgery causes less damage to the surrounding tissues and faster recovery.

The application of intelligent orthopedic robots brings higher accuracy and safety to minimally invasive surgery. The robot can provide precise positioning and navigation according to the individual differences of the patient, assisting the surgeon in the surgical operation, which greatly improves the success rate of the surgery and patient satisfaction.

Endoscopy+Robotics helps minimally invasive excellence

Traditional endoscopic fusion surgery often relies on the surgeon’s experience and preoperative CT and orthopedic radiographs to “blindly” access the site, while the precise positioning and navigation provided by PUMAI’s intelligent orthopedic robots greatly improves the accuracy and safety of the surgery.

The application of PUMA Intelligent Orthopaedic Robot combined with endoscopic technology in lumbar fusion surgery not only improves the accuracy and safety of manual surgery, but also helps to shorten the patient’s recovery time, improves the quality of life after the surgery, and enhances the overall efficiency of the surgery.

Precise Planning and Execution: With the intraoperative 3D images provided by Perlove’s 3D C-arm, the surgeon can plan the endoscopic access to the better puncture path and screw position on the navigation workstation. The high-precision robotic arm accurately completes positioning and guidance according to the pre-planned path, ensuring surgical precision while being more convenient and efficient.

Minimized trauma and bleeding: The minimally invasive surgery assisted by the Smart Orthopaedic Robot is performed through several micro-incisions, which reduces damage to the surrounding muscles, blood vessels, and nerves, and reduces intraoperative bleeding, thus shortening recovery time and lowering the risk of post-operative complications.

Protection of Vertebral Mobility: Intelligent orthopedic robot-assisted precise placement of pedicle screws can protect the vertebral body’s mobility to a greater extent, avoiding unnecessary structural injuries and maintaining the stability and flexibility of the spine.

Fatigue Resistant, Stable and Efficient: The Smart Orthopaedic Robot is fatigue free and able to perform high-precision operations continuously, which is especially important for medical teams performing multiple surgeries in a day. This consistency and reliability improves surgical efficiency and patient safety.

Reduced Radiation Exposure: In traditional open surgeries, doctors need to frequently use imaging equipment such as X-rays to confirm the position of screws. The precise navigation of an intelligent orthopedic robot reduces the use of intraoperative imaging, thereby reducing radiation exposure for both the surgeon and the patient.
