This application discloses an external positioning and guiding device for pelvic fracture channel screws. This application achieves a first repositioning of the lesion location through a percutaneous positioning guide plate with multiple spaced positioning perforations and multiple first positioning tubes connected to the base body, each equipped with a positioning and guiding component. The first positioning tubes pass through corresponding positioning perforations, abutting against the patient's iliac bone, thus achieving a second repositioning of the lesion location. Multiple first positioning pins pass through corresponding first positioning tubes and connect to the patient's iliac bone, achieving stable connection and limitation of the base body based on dual positioning, preventing base body displacement. Finally, by connecting the positioning guide tubes to the base body and passing the channel screws through the positioning guide tubes, connecting the affected and healthy iliac bones, the channel screws are positioned and oriented.

This invention relates to the field of fracture fixation technology, and more particularly to an inflatable pressure pelvic fracture fixator, comprising an L-shaped plate, an air pump fixedly connected to one side of the L-shaped plate, an air bladder fixedly connected to one side of the L-shaped plate, a rectangular groove formed on one side of the L-shaped plate, and a protrusion fixedly connected to the other side. A retaining strip is fixedly connected to the surface of the protrusion. When a patient with a pelvic fracture needs fixation, the fixator is moved from the patient's sides towards the patient's waist, allowing the L-shaped plate to extend below the patient's waist. The retaining strip on the surface of the protrusion engages with the retaining groove inside the rectangular groove, thus fixing the patient's waist. When the protrusion is inserted into the rectangular groove, a trapezoidal block is compressed into the groove. When the protrusion is fully engaged with the rectangular groove, the trapezoidal block extends out from the groove and penetrates the through groove under the elastic potential energy of the spring, thus fixing the protrusion inside the rectangular groove.

The application discloses a kind of medical instrument technical field, a kind of planning method for pelvic fracture reduction surgical screw implantation path, comprising the following steps: the implantation number of retaining screw is calculated;The implantation position of retaining screw is calculated;The implantation direction of retaining screw is calculated.The input data of the application is the three-dimensional model of each broken bone of fracture pelvis and each fracture section point cloud that is reconstructed by preoperative CT of patient and spliced reduction completion, and the final task is to automatically generate the scheme of retaining screw implantation path in operation for the fracture condition of patient, including how many retaining screws are implanted, where retaining screw is implanted, in which direction screw is implanted and how deep is implanted.The application compared with existing conventional statistical model method, can guarantee the safety and optimal implantation effect of implantation path planning on personalized case;The retaining screw implantation planning path obtained by the application has stronger stability performance;Compared with traditional manual planning method, the planning time of single screw by the application is only about 5s, and the efficiency is improved by about 20 times.

The present invention relates to a remotely controlled pelvic fracture reduction system. The remotely controlled pelvic fracture reduction system comprises a human-machine interaction automatic control unit, two or more servo drive systems, and two or more pelvic rotary push-pull devices. The human-machine interaction automatic control unit enables interactions via a human-machine interaction interface, and formulates, on the basis of an artificial intelligence algorithm of a pelvic unlocking reduction path, an automatic planning strategy for a reduction path; then each servo drive system provides a servo drive of a high-precision servo motor according to the automatic planning strategy for the path reduction, so as to drive a respectively connected pelvic rotary push-pull device to perform an axial displacement push-pull reduction action on a pelvic fracture fragment of a patient in a respective direction, thereby completing a coordinated and consistent spatial linkage with multiple degrees of freedom among the pelvic fracture fragments of the patient, achieving remotely and automatically controlled angular rotation and axial push-pull reduction on several two-dimensional planes, ensuring the intelligence, precision, and minimal invasiveness of the reduction of a severely displaced pelvic fracture, lowering the entrance threshold of pelvic fracture treatment, and simultaneously reducing fluoroscopy-induced radiation damage to medical personnel and the patient.

The present application relates to a kind of separated pelvic fixation band and tactile reference early warning system and operating method, belong to the technical field of medical instruments for war trauma first aid, including the quick inflatable pelvic fixation band and tactile reference early warning waistband of quick combination.Tactile reference early warning waistband is equipped with the tactile reference module based on high flow resistance parallel gas path principle, this module includes adjustable tactile membrane and internal damping gas path system, can the initial tension state of the abdomen of wounded person is converted into stable tactile memory reference.Two components are fixed by lateral quick connection buckle.The present application realizes the integration of pelvic fracture pre-hospital care and abdominal tension objective early warning, its all-mechanical, power-free design has very high environmental robustness and easy operation, can effectively solve the problems of uncontrollable fixed pressure and unreliable abdominal monitoring in traditional method, significantly improve the on-site treatment and transport monitoring quality of severe trauma wounded person.

The application discloses a kind of pelvic fracture postoperative intestinal function recovery methods based on multi-modal evaluation, it is related to medical postoperative rehabilitation evaluation technical field, including collecting patient postoperative gastrointestinal motility related physiological indexes, pelvic cavity imaging data, clinical manifestation text record and so on multi-modal data, pre-processing is extracted multi-modal evaluation characteristics;Characteristics are input into coevolution network, each evaluation branch parallel processing corresponding modal characteristics, through shared intermediate representation layer completes feature exchange and weight mutual adjustment, combined with the adaptive contribution degree of branch exchange after intermediate representation and own state vector calculation, weighted fusion obtains comprehensive intestinal function recovery state score, compares threshold value and determines recovery stage and matches output rehabilitation intervention suggestion.The method can realize the linkage processing of multi-modal characteristics, dynamically adapt each modal evaluation weight, improve the accuracy of intestinal function recovery evaluation, output and patient recovery stage adapt to rehabilitation intervention scheme.
