Description

Guiding robot based on projection principle and bone surgery nail placing method
Technical Field
The invention belongs to the field of orthopedic surgery screw-placing guides, and particularly relates to a guide robot based on a projection principle and an orthopedic surgery screw-placing method.
Background
The bone nail guiding and placing is widely applied to internal fixation of fracture, such as internal fixation of femoral neck fracture, internal fixation of sacroiliac screws, internal fixation of acetabulum anterior-posterior column fracture, positioning of inlets of various long tubular intramedullary nails and the like, and the nail placing point and the nail path direction need to be determined through repeated perspective in the bone nail guiding process so as to prevent the deviation of the placing position of the screw, which increases the X-ray exposure of patients and operators and increases the risk of ionizing radiation injury and tumor occurrence. Therefore, in order to reduce the difficulty of operation and improve the accuracy and safety of screw insertion, more and more advanced scientific research achievements are introduced into the medical field, and new auxiliary screw insertion technologies are developed, such as a three-dimensional navigation technology, a 3D technology, an orthopedic robot technology and the like, and provide new choices for auxiliary screw insertion. Based on the background, how to select and utilize a novel auxiliary nail placing technology and master a safe, effective, simple and feasible guiding method is the key point of the current research.
(1) Three-dimensional navigation auxiliary screw imbedding technology
The three-dimensional navigation system combines navigation technology, computer image processing and clinical operation, and utilizes a computer to process acquired parameters so as to obtain real-time three-dimensional images of a patient and surgical instruments in the operation, so that a doctor can know the relationship between the positions of the surgical instruments and the anatomical structures of the patient at any time, and the safety of the operation is improved.
Currently, the three-dimensional C-shaped arm navigation technology is widely applied to clinical application for assisting percutaneous screw fixation. Unlike traditional operation under fluoroscopy, the three-dimensional fluoroscopy can display high-resolution images of sagittal plane, coronal plane and transverse plane simultaneously, so that the operator can clearly observe the position relationship of the fracture line and the screw on the 3 sections and insert the screw under the guidance of the virtual guide pin. Therefore, the three-dimensional navigation has the advantages of providing high-quality images in the operation, having good operability, reducing the operation difficulty, improving the accuracy and ensuring quick and minimally invasive operation.
Although the sacroiliac joint screw internal fixation under three-dimensional navigation has obvious advantages, the sacroiliac joint screw internal fixation under three-dimensional navigation has the following defects and operational difficulties: acquiring a graph and establishing a navigation system requires a lot of time, because the three-dimensional C-shaped arm acquires about 100 images by rotating 190 degrees to complete image acquisition, the times and time of X-ray perspective are increased, and the time is probably more time-consuming than that of the traditional method in the initial stage of using the three-dimensional navigation auxiliary technology; navigation needs a positioning mark, invasive operation needs to be carried out on the iliac crest during positioning, the stability of the positioning mark is different due to different parts, and the accuracy of the operation can be influenced by slight movement in the operation; the scanning range of the machine is limited, and when the two sides of the machine need to be fixed by screws, the machine is difficult to fix, and even 2 times of scanning is needed, so that the perspective amount in the operation is increased, and the operation time is prolonged; the navigation system has complex operation and longer learning curve, needs training and maintenance of professional technicians, and has certain requirements on supporting facilities, such as the volume of an operating room, a passage port, a protection plate and the like, and the characteristics of each machine need to be considered. Generally, the superiority of intraoperative three-dimensional imaging navigation in sacroiliac joint screw fixation has been proved, but at present, the defects exist, and an operator needs to master relevant anatomical knowledge and has good three-dimensional image analysis capability so as to be skilled in using navigation equipment, shorten operation time and improve the safety and accuracy of navigation.
(2)3D printing auxiliary screw imbedding technology
The 3D printing technology is based on a digital model file, and can print and quickly form the bondable material layer by layer through a digital material printer to change a model on a computer into a real object. Some scholars successfully design individualized navigation templates through 3D printing and reverse engineering techniques. Through three-dimensional reconstruction generation pelvis fracture model in the research of mulcott etc. then design out screw navigation template according to reverse engineering technique, print out fracture model and baffle, carry out the pretest before the art, match baffle and bony sign in the art, accomplish through the baffle and put the nail process. Research shows that operation can be simplified by arranging the screws by depending on the individual guide plate, and the screws can be quickly and accurately arranged.
However, the design of the navigation template has certain defects: firstly, the indications are limited, and the device is only suitable for patients with fracture without displacement or patients who can meet the requirement of reduction through closed reduction; in addition, need cut open when placing navigation template and show bony landmark, it is bigger to put the nail wound under traditional perspective, need peel off adnexed soft tissue as far as in the art, provides the gomphosis of cortex and baffle, peels off the too big risk that has to cause near vascular nerve damage of scope, and peels off the accuracy that can influence the baffle inadequately, leads to putting the nail deviation.
(3) Robot-assisted screw embedding technology
In recent years, computer-guided navigation combined with robot-assisted minimally invasive internal fixation has become accepted by more and more orthopedic surgeons. Because the operator is difficult to avoid the limitation of own physiological conditions in the operation process, errors and deviations occur due to fatigue, tiny movements and the like, and the operation precision is reduced. In order to reduce human errors and fully exert the advantages of navigation equipment, the robot-assisted surgery system is applied to bone surgery. The orthopedic robot system carries out position planning by preoperative imaging, intraoperative real-time tracking and mechanical arm assistance, ensures accurate nail placement position and is suitable for percutaneous screw internal fixation operation. At present, domestic application and related research reports are more about 3 rd generation Tirobot orthopedic robot systems independently developed in China, which are also called 'breguet' orthopedic surgical robots.
In the process of fixing fracture by guiding and nailing, an orthopedic robot system represented by Tirobot mainly has the following characteristics: the positioning is accurate: the robot system can provide accurate space positioning, the precision is 0.6-0.8 mm, and the screws are accurately, safely and stably placed into corresponding anatomical parts through the operation of the mechanical arms, so that the risk of blood vessel and neuro-iatrogenic injury is reduced. Monitoring in real time: the Tirobot can realize real-time optical tracking in the operation, repeated perspective is not needed in the operation process, and if the position in the operation deviates, the system can remind a surgeon to further calibrate. ③ the radiation quantity is low: compared with manual nail placement, the robot navigation obviously reduces the X-ray fluoroscopy times in the operation, thereby reducing the ionizing radiation damage to doctors and patients caused by radiation in the operation. Fourthly, autonomous operation: after the operator manually plans the path of the nail path, the subsequent operation can be finished by the system according to the programmed path, and the doctor is guided to finish the operation efficiently and safely. In addition, the robot system adopts modularization, miniaturization and universal design, can realize separation of operation planning and operation, and can implement remote operation through the Internet.
However, the current orthopedic robot system still has certain limitations: first, surgical robots can only solve the problem of precise positioning, and the path planning of screws still relies on the experience of the surgeon and needs to be done manually, which may have subjective errors. Secondly, good reduction is the basis of accurate positioning, and percutaneous sacroiliac joint screw fixation is suitable for patients who can obtain good reduction through closed reduction; and for patients with large fracture displacement and unsatisfactory reduction, the fixation cannot be realized in the mode. Thirdly, the orthopedic robot navigation positioning system is inexperienced in the early application, and the deviation of the guide pin can be caused. Finally, the orthopaedic robot is expensive in equipment cost, complex in operation, difficult in assembly and detection, high in maintenance cost and requires professional training, and the factors limit the clinical popularization of the orthopaedic robot.
Therefore, a guiding robot and a nail placing method for orthopedic surgery, which are simple in operation, low in cost, low in equipment requirement and less in nail placing wound, are needed to be provided.

Although modern orthopedic surgery requires that before internal fixation of fracture, a doctor should determine the direction of bone screw placement and the point of screw insertion as much as possible by means of auxiliary screw placement equipment, and avoid wound enlargement caused by intraoperative adjustment as much as possible, in fact, auxiliary screw placement technologies including a three-dimensional navigation technology, a 3D printing technology and an orthopedic robot technology or auxiliary screw placement technologies which depend on the experience of the doctor are high in equipment cost and large in operation difficulty, and are difficult to popularize and apply in primary hospitals.
In order to solve the technical problems, the technical scheme of the invention provides an auxiliary nail placing scheme which is low in cost, simple in operation, low in equipment requirement, easy for clinical popularization and high in nail placing accuracy.
The "bone nail" and "nail" referred to in the present invention may be a k-nail, a screw, and other rod-shaped fixtures used in internal fixation of bone fractures.
In the traditional method for guiding the nail by using the radiography device, the nail inserting point and the nail path direction need to be determined through repeated perspective in the bone nail guiding process so as to prevent the deviation of the screw inserting position, because the propagation direction of X-rays emitted by a light source of the X-ray radiography device is generally divergent (as shown in fig. 1), the projection image of the right position or the lateral position of the bone nail is changed due to the vertical or horizontal movement of the bone nail, and the requirement that a doctor needs to perform the perspective again so as to improve the accuracy of the positioning of the bone nail is met.
The guide robot and the bone surgery nail placing method provided by the technical scheme of the invention are based on the characteristic that X-rays are radiated along a straight line and the principle that radiography is not changed when an object moves along the X-ray radiation direction, can respectively determine the nail placing planes of the surgical bone nail in two radiation directions of a 90-degree intersection angle through the positioning guide nail, and determine the unique and optimal nail placing position through the two intersecting planes, wherein the nail placing position has the optimal nail inserting point and the optimal nail placing path, and the process of determining the surgical bone nail by utilizing the positioning guide nail in an auxiliary manner is completed in vitro.
Particularly, when the doctor is fixed a position in the art, first location is led the nail, second location is led nail and third location and is led the nail and should place in human near light source one side, at this moment, the doctor can observe the perspective image of location guide nail and skeleton, and simulate out the best nail point of inserting and put the nail route of operation bone nail in vitro according to perspective image, and in the operation process, the doctor only need pay close attention to the projection of operation bone nail in a radiation direction at the same moment, be favorable to reducing the bone nail location degree of difficulty, shorten operation operating time, reduce the radiation injury of patient's operation surface of a wound and perspective to patient and operative person.
The application environment of the present invention is not limited to the X-ray imaging apparatus, and in fact, any radiographic apparatus satisfying the straight line radiation characteristics may be applied.
The following describes and explains the guiding robot based on the projection principle and the bone surgery nail setting method using the guiding robot in detail with reference to the specific embodiment and the accompanying fig. 2-4.
The first embodiment of the invention:
the embodiment of the invention provides a guiding robot based on a projection principle, which is used for assisting an intraosseous built-in nail in cooperation with an X-ray radiography device and comprises a guiding nail placing device 1 and an adjusting mechanism 2, wherein the adjusting mechanism 2 is used for driving the guiding nail placing device 1 to move to any preset position, and a long shaft of the guiding nail placing device 1 extends along the vertical direction and is sequentially provided with a primary positioning part 11 and a secondary positioning part 12 from top to bottom. In the present embodiment, the primary positioning portion 11 and the secondary positioning portion 12 are used to respectively determine nail placing planes of the surgical bone nail 3 on two X-ray radiography apparatuses configured in different radiation directions, the primary positioning operation is completed under the X-ray configured in the vertical radiation direction, the obtained radiography image is a "positive plate", the secondary positioning operation is completed under the X-ray configured in the horizontal radiation direction, at this time, a "side plate" is obtained, it should be noted that, in other embodiments, the radiation direction is not limited to be horizontal or vertical, and only it needs to be satisfied that the two radiation directions are perpendicular.
