The utility model relates to the technical field of medical instruments, in particular to a distraction reduction fibula far-end bone fracture plate which comprises a head portion, a neck-trunk portion and a trunk portion which are integrally arranged, the width of the head portion is larger than that of the trunk portion, the head portion is provided with a plurality of locking holes arranged at intervals, the trunk portion is provided with a plurality of through holes arranged at intervals, and the through holes are communicated with the neck-trunk portion. The through hole is a combination hole formed by overlapping a threaded round hole and a non-threaded pressurizing hole groove part, the long axis X of the combination hole is arranged in the length direction of the stem part, and the pressurizing hole groove is arranged close to one side of the head part. The pressurizing hole groove in the combination hole is arranged close to one side of the head of the bone fracture plate, so that the pressurizing direction of the pressurizing hole groove is far away from the fracture end of the far end of the fibula, the stretching reduction of the fracture end is realized, and the treatment effect of the fracture of the far end of the fibula is effectively improved.

The simple configuration improves the ease of adjusting tension. [Solution] A frame that fixes the mesh by a rectangular main frame (frame) 20 composed of four sides having a U-shape with an open outer side, and holding parts 10 provided corresponding to each of the four sides, wherein the holding part 10 is provided so as to be slidable inward and outward relative to the main frame (frame) 20 while in contact with the lower surface of the upper part of the U-shape of the main frame (frame) 20, and comprises a sliding part 11 having a groove 11a at its upper part that is aligned with the long axis of the main frame (frame) 20, a holding shaft 12 disposed inside the groove 11a, and a fixing member 13 that positions and fixes the sliding part 11 so as to fix the mesh sandwiched between the sliding part 11 and the holding shaft 12.

In the present invention, a toothbrush is provided with a handle body formed from a hard resin, and a brush part formed from a soft resin. The brush portion has a brush base portion and filaments. The filaments protrude from the brush base portion toward one side in the thickness direction. The handle body is provided with a neck part, a connecting part and an embedding part. The connecting portion, the fitting portion, and the brush base portion constitute a head shaft portion. The connecting edge portion is an end portion on one side of the connecting portion in the long axis direction and an end portion on one side of the connecting portion in the width direction. The neck edge portion is an end portion on one side in the width direction of a portion where the dimension in the width direction of the neck portion is smallest. The maximum dimension of the head shaft portion in the thickness direction is 3.0 mm or more and 4.5 mm or less. The minimum dimension of the neck portion in the width direction is 3.0 mm or more and 4.5 mm or less. An angle formed by a first imaginary line passing through both the connecting edge portion and the neck edge portion and the central axis is 17-28 DEG.
