This disclosure introduces a foldable bath frame comprising a body and a limiting assembly. The body consists of a first and second frame connected by a flexible seat. The limiting assembly at the bottom features a first mounting part on its first end, which detachably couples with the first frame's mounting cavity, and a second mounting part on its second end, pivotally connected to the second frame's mounting cavity. This design enables conversion between unfolded and folded states. The flexible seat deforms to facilitate folding/unfolding, while the limiting assembly's reinforced connections ensure both portability and structural stability, balancing convenience with durability in the foldable structure.

The present application relates to a posture display method, a device and a system for a guiding channel, and readable storage medium. The posture display method of a guiding channel includes determining an original position relation between a three-dimensional affected limb image and a virtual guiding channel displayed in a monitor according to an original position relation between the guiding channel and an affected limb and obtaining posture change data of the guiding channel. The method further includes adjusting the posture of the virtual guiding channel based on the posture change data, so as to the relative position relation between the virtual guiding channel and the three-dimensional affected limb image matches with the relative position relation between the guiding channel and the affected limb.

The present invention relates to the technical field of silk scaffolds, and in particular, to a silk/pet mix-woven scaffold and a preparation method and use thereof. The silk/PET mix-woven scaffold is formed by weaving silk and PET fibers. Sericin of the silk is removed. The silk and the PET fibers are mixed and knitted. The PET fibers provide reliable fixation in an early stage to maintain the stability of mechanical properties, and the silk degrades gradually in a later stage to promote the growth of new tissues to achieve the integration of the scaffold and the body. When the scaffold is used for artificial tendon/ligament recovery, its overall performance is better than that of pure silk or pure PET fiber scaffolds, and the scaffold has excellent clinical transformation potential.
