This utility model provides a ship auxiliary support device, relating to the field of auxiliary support technology, for installation within the abdominal cavity of a ship's skeletal structure. The auxiliary support device includes: two support seats disposed within the abdominal cavity and respectively connected to two surfaces of the skeletal structure; a pressure sensor disposed on one of the support seats and connected to one surface of the skeletal structure; and a telescopic component, with both ends hinged to the two support seats. The telescopic component and the pressure sensor are signal-connected to the ship's control unit. The pressure sensor can send pressure signals to the control unit, which can control the telescopic length of the telescopic component based on the pressure signals. This auxiliary support device effectively solves the problems of poor stability and unadjustable support force of traditional wooden wedge supports, extends the service life of the structure, improves the ship's operational efficiency, and enhances the ship's operational safety.

It includes: a dummy skeleton, a base at the bottom of the dummy skeleton, and cushioning material filling the dummy skeleton; the dummy skeleton has a human skeletal structure, and supporting water pipes are connected to the lower part of the dummy skeleton; the base is a stable support structure, and connecting pipes in the vertical direction correspond to the number and diameter of the leg water pipes and supporting water pipes of the dummy skeleton; the leg water pipes and supporting water pipes of the dummy skeleton are inserted into the corresponding connecting pipes. The dummy skeleton and chassis are constructed using water pipes, supplemented with foam or sponge to cushion impact forces, and finally clothed to complete the dummy, significantly reducing costs.

The invention discloses a spiral adaptive aortic dissection stent which comprises an annular stent body composed of multiple sets of fiber modules, every two adjacent sets of fiber modules are connected in a biological bionic mode and are in smooth transition through degradable polymers or composite materials, and each set of fiber module is formed by connecting two parts of skeletons. The dense skeleton corresponds to a false cavity proportion range, and the sparse skeleton corresponds to a true cavity proportion range. The design method of the spiral adaptive aortic dissection stent comprises the following steps: partitioning the aortic dissection according to a symbolic anatomical position and a main blood vessel branch of an abdominal aorta; designing a stent fiber module, and determining periods and numbers of dense skeletons and sparse skeletons in each aortic dissection area; and assembling the bracket body. The spiral adaptive aortic dissection stent can better adapt to the spiral morphology characteristics of the aortic dissection true cavity, and formation of new dissection crevasses induced by the tail end of the stent is reduced.

A spinal implant consists of a main structure made of synthetic or metallic material, or a combination of both, and stem cells in a coating, sheet, sheath, or membrane applied to the surfaces of the main structure, or filled with a plug of stem cell-containing material. The main implant structure preferably has an opening or channel. The spinal implant may include anchor holes for fixing it to the skeletal structure of the spine using fasteners, or it may simply be held in place between adjacent vertebrae.

This invention relates to the field of oral medical diagnostic and identification technology, and provides a decision-making method and system for maxillary arch expansion diagnosis and expander selection. The method includes: S1: acquiring and verifying multiple mandatory parameters such as dentition stage, patient age, transverse width of maxillary and mandibular teeth, transverse width of maxillary and mandibular skeletal structure, bone or tooth expansion requirements, and midpalatal suture stage; S2: performing anchorage determination based on dentition type to obtain anchorage status; S3: inputting the structured parameter set into a hierarchical decision tree algorithm, using whether the bone or tooth expansion requirements have reached a preset activation threshold as the initial judgment condition, matching decision branches layer by layer according to a preset priority order, and arbitrating according to the anchorage safety priority rule when multiple candidate schemes conflict, outputting a maxillary arch expansion scheme; S4: outputting the maxillary arch expansion scheme and its corresponding judgment basis. This solves the problems of subjective judgment of midpalatal suture maturity, inaccurate estimation of skeletal and dental expansion amounts, and lack of a unified standard for assessing anchorage conditions at different dentition stages.
