The invention discloses a multifunctional splint for clinical use in orthopedics. The multifunctional splint comprises a bottom plate, wherein the upper surface of the bottom plate is fixedly connected with the lower surface of a first splint through a support plate; the right side surface of the support plate is fixedly connected with the left side surface of a slider through a first telescopic device; the slider is glidingly connected in a slide groove formed in the upper surface of the bottom plate; the upper surface of the slider is fixedly connected with a second splint. According to themultifunctional splint for clinical use in orthopedics, under cooperation of the first splint, the second splint, second telescopic rods, second springs, permeable plates, a first telescopic rod, a first spring, the slider, the slide groove, a traction
rope, a first rotating shaft, a first bearing, a take-up spool, a fixing plate, a second bearing, a second rotating shaft and a
handle, multiple functions are realized, breathability of the splint is guaranteed, and clamping distance between the first splint and the second splint can be adjusted, so that work of a medical worker is facilitated.
