This invention provides an internal fixation device for cancellous bone, belonging to the field of medical device technology. It includes a fixation plate with a plurality of screw holes and positioning holes arranged in a linear array on its top outer wall; and a guide assembly connected to the fixation plate, used to guide the hollow self-drilling screws. By incorporating the guide assembly, this invention not only guides the hollow self-drilling screws, preventing them from deviating from their pre-operatively assessed position during insertion, thus affecting their fixation effect on the fracture site, but also holds the screws during the guiding process, preventing the screw head from tilting and protruding, which could cause skin irritation and affect postoperative recovery.

The present application relates to the medical image intelligent recognition, three-dimensional reconstruction and medical rapid prototyping technical field, solve the defect that ultrasound, nuclear magnetic imaging is not intuitive to deep lesion, there is no 1:1 entity reference before operation, the communication difficulty of doctor and patient, the system contains the shell, high-definition display module, self-locking angle support and four core components: (1) ultrasonic detection assembly (ultrasonic probe acquisition assembly), (2) image processing mainboard (AI image main control processing machine case), (3) high-precision servo drive module, (4) 3D precision printing forming bin.Probe acquisition pelvic ultrasound data, complete lesion segmentation and three-dimensional reconstruction by AI, and print entity model.The present application adopts self-developed AI, clearly shows the relationship between lesion and pelvic floor, rectum, ovarian infiltration, adapts to gynecological difficult lesions, and assists clinical preoperative evaluation.

This invention provides an artificial intelligence-based multimodal preoperative assessment method and system for cochlear implantation, relating to the field of artificial intelligence medical technology. The method includes extracting multimodal medical image features, identifying and describing anatomical variations, constructing a three-dimensional anatomical structure, and annotating key information. Based on this, candidate implantation paths are generated. Through spatial sampling and sequence modeling, the cumulative risk during surgical instrument advancement is dynamically predicted, generating a time-series risk curve and multidimensional risk assessment features, ultimately determining the preoperative risk assessment result. This invention achieves dynamic, quantitative, and prospective assessment of cochlear implantation surgery risks.

This invention discloses a method for synergistically relieving fracture pain through a Qi-regulating and blood-activating plaster and acupressure application, belonging to the field of integrated traditional Chinese and Western medicine orthopedic nursing. The Qi-regulating and blood-activating plaster is composed of Corydalis Rhizome, Panax Notoginseng, Angelica Sinensis, Frankincense, Myrrh, Ligusticum Chuanxiong, Salvia Miltiorrhiza, and Carthamus tinctorius in specific weight proportions, processed by vinegar-processing, ultrafine pulverization (100 mesh), and shaping with rice wine. Its preparation method includes raw material pretreatment, processing of medicinal slices, low-temperature drying, ultrafine pulverization, weighing and mixing, and preparation of the plaster before use. The application method involves preoperative assessment, followed by standardized acupressure operation along meridians until Qi is obtained, then applying the Qi-regulating and blood-activating plaster to the pain area centered on the Ashi points, and finally fixing and dynamically assessing the condition. This invention closely addresses the pathogenesis of fractures as "Qi stagnation and blood stasis, pain due to obstruction," achieving a synergistic effect of "immediate analgesia + long-term therapeutic effect." Clinical data show that the NRS score decreased by ≥3 points within 2 hours of intervention, the total effective rate was 92.5% within 7 days, the skin allergy rate was only 2.1%, and the transdermal absorption rate was 46.2%. It has the advantages of taking into account both symptoms and root causes, being safe and controllable, easy to operate, and being adaptable to individual needs. It can be operated independently by nursing staff and is suitable for all orthopedic scenarios.

The application provides a method for dredging the governor vessel and adjusting the spine for rehabilitation physiotherapy, and belongs to the technical field of spine adjustment physiotherapy. The method comprises the following steps: step one: preoperative evaluation and diagnosis: a doctor first determines the specific segment and degree of spinal dislocation and subluxation of a patient through body posture analysis, spinal palpation, and image examination, simultaneously evaluates the spinal joint mobility and stability, and excludes contraindications such as fractures and tumors that are not suitable for spine adjustment, accurately locates the lesion site that needs to be adjusted, and lays a foundation for subsequent operations; the application adjusts the prone posture of the patient in a targeted manner, cooperates with different specific actions, pulls the reflection to a certain specific vertebral facet joint, and then uses a spine adjustment device to accurately tap the misaligned part of the spine, promotes the reduction, releases the pressure of the vertebral body, restores the function of the compressed nerve, stimulates the qi and blood of the governor vessel, and achieves the purpose of dredging the governor vessel, thereby improving the effect of the method for dredging the governor vessel and adjusting the spine for rehabilitation physiotherapy.
