To provide image processing programs and the like that can generate image data and images that enable more adequate evaluation and diagnosis than conventional methods. [Solution] The present invention's image processing program is characterized by causing a computer to execute the following: an image acquisition process in step S305, which acquires a plurality of image data obtained by performing CT scanning of the hip joint of a subject; an image generation process in step S310, which generates display image data for displaying a predetermined image on a display device based on the plurality of image data acquired in the image acquisition process in step S305; and a first region identification process in step S320, which identifies a first region that is a necrotic area of ​​the femur surrounded by a plurality of image data corresponding to the femur, where the CT value is greater than that of a normal bone, based on the display image data of the femur in the hip joint generated in the image generation process in step S310.

The invention discloses orthopedic nursing drilling equipment, belongs to the technical field of orthopedic nursing, and provides the following scheme that the orthopedic nursing drilling equipment comprises a drilling supporting mechanism, a drilling mechanism is arranged on the drilling supporting mechanism, the drilling supporting mechanism comprises two adjusting assemblies, and guide assemblies are arranged at the opposite ends of the two adjusting assemblies; a mounting cylinder is arranged on the guide assembly; the air pressure type limiting assembly makes contact with the affected part of a patient, when muscle spasm or unconscious activity of the affected part of the patient occurs, the air pressure type limiting assembly deviates, the locking state of the drilling assembly is relieved through air control, and at the moment, the adjustable alarm assembly drives the drilling assembly to recycle a drill bit and sends out a sound-light alarm signal to remind medical staff to conduct treatment in time; the situation that the drill bit continuously drills due to displacement of an affected part, and surrounding normal bone tissue, blood vessels and nerves are damaged is avoided, the problems that secondary damage is easily caused by displacement of the affected part and safety early warning is lacked are effectively solved, and therefore the safety of drilling operation of orthopedic nursing is remarkably improved.

The invention discloses a 3D printing Ti metal bone trabecular acetabulum reconstruction pile and an operation method thereof, the 3D printing Ti metal bone trabecular acetabulum reconstruction pile comprises a plurality of reconstruction piles corresponding to the ilium, the pubis and the ischium, and adaptive acetabular cup prostheses are arranged between the reconstruction piles; the reconstruction pile comprises a pile body, one end of the pile body is a conical head end, the other end of the pile body is a tail end, a hollow hole channel allowing a guide pin to penetrate through is formed in the pile body in the axial direction, holes are distributed in the side wall of the pile body, and the stable foundation of the acetabulum is expanded to normal sclerotin of the ilium, the ischium and the pubis. The reconstruction pile is arranged in the medullary cavity of the part to form stable support, the bone cement is connected with the acetabular cup prosthesis, the shape and degree of acetabular bone defects do not need to be considered, the method is suitable for reconstruction of all types of acetabular bone defects, and the problem that a traditional method is limited in adaptation range is solved.

The application relates to the technical field of implanting bone surgery, in particular to a proximal tibia anatomical bone defect pad block prosthesis which comprises a pad block prosthesis structure and a side plate, the pad block prosthesis structure comprises an anatomical bone defect pad block and a sleeve cage structure fixed at the bottom end of the anatomical bone defect pad block, and the side plate is arranged on the side of the anatomical bone defect pad block. Through the arrangement of the pad block prosthesis structure and the side plate, on the basis of minimal osteotomy of proximal tibia bone defect, the anatomical bone defect pad block and the anatomical prosthesis with sleeve cage structures on two sides are customized according to the internal bone defect condition, the normal bone joint surface can be reserved, the amount of osteotomy is reduced, the normal patellar ligament and tibial collateral ligament are reserved, the joint function is maximally maintained, the pad block prosthesis structure and the side plate can provide initial stability and provide a structural basis for long-term stability, and the hollow sleeve cage structures on the two sides can be implanted with bone, have a bone guiding effect and can promote the formation of new bone.

The application provides a template image-based bone marrow abnormal chromosome detection method, device and medium. The method comprises: acquiring a bone marrow chromosome image to be detected; determining a target category of chromosomes in the bone marrow chromosome image through a trained and tested classification model; selecting a template image corresponding to the target category from a template library, wherein the template library stores a plurality of images representing normal bone marrow chromosomes; inputting the template image and the bone marrow chromosome image into a trained and tested difference analysis model to obtain a detection result, wherein the detection result comprises identification information representing whether the chromosomes in the bone marrow chromosome image are normal or abnormal, and an abnormal type corresponding to the abnormality when the chromosomes are abnormal. In this way, the accuracy of chromosome abnormality detection can be improved.

The utility model discloses a long bone fracture dislocation reduction fixator which comprises an arc-shaped bottom provided with an arc surface, and the arc-shaped bottom supports a normal bone and a dislocation bone through the arc surface; the upper reduction forceps comprise an upper handheld end and an upper occlusion end; the lower reduction forceps and the upper reduction forceps are connected through a rotating shaft, the lower reduction forceps comprise a lower handheld end and a lower occlusion end, the upper occlusion end abuts against the arc-shaped bottom, and the lower occlusion end abuts against the malposed bone; the bone screw is arranged on a normal bone, and at least part of the bone screw extends into a dislocated bone. During reduction, the upper occlusion end abuts against the arc-shaped bottom, the lower occlusion end abuts against the malposed bone, the malposed bone is reduced to the normal position, the medullary cavity axis of the malposed bone coincides with the medullary cavity axis of the normal bone, at the moment, the malposed bone is fixed to the normal bone through the bone screw, reduction of the bone is achieved, and it is guaranteed that the fracture position does not deviate or distort any more.

The application discloses a layered and blocked bone cement spacer and a preparation method thereof, and belongs to the technical field of orthopedic clinical treatment. After complete lesion removal, flushing and disinfection are completed, antibiotic bone cement is filled in a layered filling manner, S1: a first layer thin layer filling step: the prepared antibiotic bone cement is uniformly filled on the inner wall of a lesion gap in a thin layer smearing manner, the bone cement is fully attached to the bone wall in a soft pressing manner, a bone cement thin layer with a thickness of 2-3 mm is formed, the bone cement thin layer completely covers the inner wall of the lesion gap and is closely attached to the normal bone cortex, gaps are avoided, the layered filling manner of the thin layer and the block is adopted, the thin layer and the block are not completely fused, and slight gaps exist between the blocks, in a second operation, the thin layer can be first separated from an induction film by prying, and then the blocks are taken out one by one, without forcibly stripping, the difficulty of taking out is greatly reduced, the operation time is shortened, and the operation operation strength is reduced.
