The brush molded body has a head base part, and a plurality of filaments extending from a supporting surface of the head base in a long axial direction. The filament has a recess which opens on one side in a first direction and is recessed on the other side in the first direction. The recess has: a first opening end located at an end on one side in the first direction and located on one side in a second direction; a second opening end located at the end part on one side in the first direction and located on the other side in the second direction; and a bottom end part located on the farthest other end side in the first direction and located at a prescribed position in the second direction. Of the plurality of filaments, second filaments adjacent to one side in the first direction relative to a first filament has at least a part of an outer wall located on the farthest other side in the first direction located between a first border line passing the bottom end part in the first filament and the first opening end and a second border line passing the bottom end part and the second opening end.SELECTED DRAWING: Figure 8

A multipurpose foot-powered system is disclosed which is a set of foot-powered and hand-operated tools which break up the structure of compacted earth. Specifically, the system comprises a kick-pick tool and a twist-pick tool. The kick-pick tool measures approximately 5-6 feet in length. It resembles a shovel with a hooded steel pick or hooded chisel tip for a blade. The blade is slightly curved like a shovel and an integral footrest is positioned at a convenient distance from the tip of the hooded blade, which will allow the user to drive the hooded blade into the earth with their foot. The twist-pick tool is similar in design, however the tool is entirely straight from its tip through its handle. The footrest height is adjustable by the user and the handle has a T-shaped crossbar that enables a user to twist the hooded blade about the long axis of the twist-pick.

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.

A method of manufacturing an interface for a body part is described. The method includes the step of selecting an inner radial dimension of the interface to have a plurality of compression areas that extend along the long axis of the interface. The method also includes the step of spacing the plurality of compression areas circumferentially around the long axis of the interface to create a compression pattern. The compression pattern is sized and dimensioned to reduce motion of the skeletal structure towards a wall of the interface when the interface is worn on the body part by compressing soft tissue of the body part against the skeletal structure.

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.

To achieve oral cavity operability and firm polishing feelings by transmitting the force applied to a grip part to a bristle-implanted part surely while suppressing bending of a neck part.SOLUTION: A toothbrush 100 includes a brush body 110 including a head part 10 having a bristle-implanted surface 11 arranged on the tip side in a long axis direction, a neck part 20 arranged on a rear end side of the head part 10, and a grip part 30 arranged on the rear end side of the neck part 20. The neck part 20 has a straight shape having a vertically long flat roughly square cross-sectional shape, and extends along the long axis direction with the length D1 and the length W1 being constant values when the length in a thickness direction of the neck part 20 is represented as D1 and the length in a width direction is represented as W1, and the length W1 and the length D1 satisfying the relationship of D1>W1.SELECTED DRAWING: Figure 1

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.
