In the field of spine surgery, the high complexity and risk of clinical surgery puts forward higher requirements for pre-, mid- and post-surgical image verification, surgical equipment, operator experience and operation techniques. In specific clinical applications, PUMA Orthopaedic Minimally Invasive Robot can be widely used in multi-segmental spine surgery, assisting doctors to locate the lesion site, providing preoperative surgical process planning for spine surgery (percutaneous vertebroplasty, pedicle screw internal fixation and other surgeries), visual guidance of the nail position and angle, and simulation assistance for the nail insertion, and so on. Do you know what are the advantages of using minimally invasive orthopedic robots for vertebroplasty?
What is Vertebroplasty?
Vertebroplasty, known as Percutaneous vertebra pasty (PVP), is a minimally invasive spinal surgery that involves making a small incision of about 3mm on the skin surface, and then injecting bone cement (polymethylmethacrylate) into the diseased vertebrae after surgical tools pass through the incision to enter the diseased vertebrae along the bony structures in order to alleviate the patient’s pain, restore vertebral body height, increase vertebral body stability, and strengthen the vertebral body. The injection of cement (polymethylmethacrylate) into the diseased vertebral body can relieve pain, restore the height of the vertebral body, increase the stability of the vertebral body and strengthen the vertebral body.
What are the advantages of minimally invasive orthopedic robot for vertebroplasty?
At present, orthopedic surgery is generally “dangerous, difficult, blind, lack of” four major problems. Dangerous: adjacent to important blood vessels and nerves; difficult: narrow space in the operation area, difficult to operate the instruments; blind: the eyes can not see the actual operation area, to imagine the structure of the bones in the brain; lack of: the lack of personalized surgical plan for the patient.
Spine surgery is known as “dancing on the tip of the knife”, these four problems are particularly prominent, has always been extremely dependent on the operation of the doctor, the entire operation of the doctor’s energy is also a small test. For young doctors, without several years or hundreds of operations to learn and familiarize themselves with, they simply can not reach the conditions of surgery alone.
Through the use of minimally invasive orthopedic robot-assisted navigation and positioning technology, the doctor can make targeted planning based on the patient’s 3D C-arm image before surgery, and the minimally invasive orthopedic robot is responsible for accurately moving the robotic arm to the puncture path preset in the pre-operative planning during surgery, with a margin of error of less than 1 millimeter, so that the doctor can “see and hit where you want to hit,” and the surgeon “can see and hit where you don’t want to hit. The error is less than 1mm, so that the doctor can “see, hit accurately and hold steadily”.
If we use an example from life to make an analogy, it is like we drive a car and use navigation software, we want to get to a place, the application of map navigation is extremely accurate and fast method.
There are three steps to realize the navigation function:
- Enter the starting point and end point
- Select the route
- Follow the navigation prompts to move forward
In minimally invasive orthopedic robot-assisted surgery, the patient’s needs are equivalent to inputting the starting point and end point, inputting the 3D image into the special software for planning and designing is equivalent to choosing a route, and intra-operative operation is equivalent to advancing according to the navigation prompts. the image captured by the 3D C-arm is equivalent to the real-time road condition, which provides the doctor with an even more accurate 3D “map”, and the robot then guides the doctor to the place. The images captured by the 3D C-arm during the operation are equivalent to real-time road conditions, providing the surgeon with a more accurate 3D “map”, and the robot then guides the surgeon to follow the “map” for an accurate driving “navigation system”, and the combination of the two realizes the precision and intelligence of the operation.
It is true that for experienced doctors, they are the “old drivers” and do not need a map to reach their destinations, but with the minimally invasive orthopaedic robot, the entire surgical process will undoubtedly become easier, and the success rate of the surgery will be better guaranteed! For young doctors, the robotic system will help them even more by eliminating the need to find and ask for directions!
Minimally invasive orthopedic robotic-assisted vertebroplasty has the advantages of less trauma, faster postoperative recovery, better treatment results and fewer postoperative complications. At the same time, since it is not necessary to determine the position of nail placement through repeated fluoroscopy, thus it can reduce intraoperative radiation and greatly reduce the radiation hazard for patients, and the surgical process is completed by the minimally invasive orthopedic robot together with the attending surgeon, which greatly increases the safety of the surgery.
