The present invention discloses a clamp device for cutting hoof food materials, which cooperates with two sets of saw blades for longitudinal cutting and transverse cutting in a sawing machine to cut on its transverse incision and longitudinal incision, and the clamp is responsible for clamping the hoof food materials. For this clamp, the clamping mechanism is driven to clamp by a driving device. In addition to the initial clamping mechanism, the clamping and pressing component in the clamping mechanism also has a secondary clamping component, which can use the lever principle to perform a secondary clamping action on the upper end clamp after the initial clamping, thereby strengthening the clamping force. Secondly, in individual processes such as cutting of cattle hooves, considering that the saw blade may slip or part of the material block may fly out due to the loosening of the clamping mechanism when cutting the hard cattle hoof, a downward pressing locking mechanism is provided here, which adopts the inclined surface matching method, and uses the tension and pressure screw to match the lowering of the lifting plate to clamp and lock the locking rod connected to the clamp, so that the entire clamping mechanism is locked, and the cutting saw blade will not slip during cutting.

Through the application of the utility model, the short and wide distal radius steel plate is provided, the smaller size of the steel plate is more favorable for implementing the operation scheme of transverse incision on the palm side of the wrist, and meanwhile, the accuracy of placing the steel plate is also improved, so that the operation efficiency of medical personnel is further improved; in addition, the incision needed by using the anterior rotating muscle fixing device is small, meanwhile, the integrity of the anterior rotating muscle of the patient is kept, and the postoperative rehabilitation time of the patient is greatly shortened.

Devices and techniques for adjusting an alignment for a first metatarsal may include making a plurality of cuts along the length of the first metatarsal. In different applications of the technique, a plurality of transverse cuts may or may not be made intersecting the longitudinal cuts. In either case, the cuts can separate the first metatarsal into two individual portions and release a removable wedge of bone. The different portions of the metatarsal can be moved relative to each other to adjust an anatomical alignment of one portion relative to another portion, for example in multiple planes. After suitably adjusting the alignment of the different bone portions, the portions can be fixed together.

The present disclosure describes a microfabricated intravascular device configured for high axial strength, while the microfabricated intravascular device also maintains effective flexural flexibility. A pipe member includes a series of circumferentially extending rings that are interconnected by a series of axially extending beams. The transverse cutouts separate and define the rings. A series of axial cutouts are aligned with the beam and extend partially from the beam into the adjoining ring such that the beam length is nested partially within the axial length of the adjoining ring. This increases the functional length of the beam to provide flexural flexibility while still having sufficient ring structure to provide effective axial stiffness.

The tire has a mean radial distance E1m between: - the surface (100) passing through the radially innermost point of the deepest cutout (26, 28) and substantially parallel to the rolling surface (16), and - the radially outer surface (102) passing through the radially outermost points of the radially outermost reinforcing elements (720) among the reinforcing elements of the radially outermost layer (72) such that E1m ≤ 2.0 mm. The first axially lateral portion comprises a linear density DR1 of first transverse grooves and a linear density DI1 of first transverse incisions satisfying DR1 ≤ 0.43 cm-1 and DR1 + DI1 ≥ 0.45 cm-1.

This invention discloses a super-absorbent surgical pad for preventing fluid leakage during cesarean section, relating to the field of surgical pads. It includes a protective mechanism comprising a pad body and an edge seal fixed to the periphery of the pad body. The pad body includes a skin-friendly antibacterial drainage layer, a water-locking core layer, and a breathable anti-backflow covering layer. An operating mechanism includes an incision assembly mounted on the pad body. This device, by using a single, integrally molded pad body, eliminates the need for assembling multiple pads and precisely covers the pubic bone, transverse incision, and surrounding easily contaminated areas. Its stable placement is achieved through its own area, weight, and natural fit to the abdominal contour, eliminating the need for external instruments such as towel clamps, clips, or tape for fixation. Furthermore, the I-shaped incision assembly on the pad body allows for flexible access to the initial surgical incision and intraoperative incision extension.
