できないものでめった。Conventional external fixators have been designed to perform their functions under various fixation situations, primarily for the fixation of large bones. However, this external fixator has a complicated structure and is large, making it unsuitable for fixing small bones in hands and feet. Due to the above problems, it is difficult to make the device smaller and simpler, and it has rarely been possible to fix or lengthen fractures or damaged ossicles.

ンプの締付けねじの軸と直交配置させている。In order to achieve the above object, the small external fixing device of the present invention is composed of a small metal rod or a metal frame provided with one clamp. A plurality of bottles for bone fixation are positioned on the same plane by two clamps. Each clamp consists of/a pair of jaws and a clamping screw, with at least l
The jaw of the clamp is provided with a threaded portion that is inserted into a metal rod or a long hole drilled in the metal rod, and also has a sliding surface that comes into contact with the side surface of the metal rod. A screw hole is formed in the threaded portion, and a threaded rod that is threaded into the screw hole is inserted into the elongated hole. The axis of the threaded rod is arranged perpendicular to the axis of the tightening screw of the clamp.

ッド軸に平行する同一面上に保持される。When the threaded rod is rotated, the threaded part moves in the axial direction VC of the threaded rod, but the jaw that is connected with this threaded part has a sliding surface that comes into contact with the side surface of the metal rod, so it cannot rotate. It is not moved, but slides along the side of the metal rod in the axial direction of the rod. Therefore, the movable clamp having the jaw as a component moves in the axial direction of the rod as the rod rotates, and the front support bin held by the clamp also moves in parallel in the axial direction of the rod. Therefore, even when the threaded rod is rotated to elongate the bone and the two clamps are moved apart, the bottles held by both clamps are held on the same plane parallel to the rod axis. .

とができる。According to the small external fixator of this invention, since it is small, it is possible to support and fix small bones such as metacarpals with the bottle held between both clamps, and when elongating the bone, the threaded rod can be rotated. Accurate treatment can be performed with simple operations such as moving.

る。A long hole 18 extending in the longitudinal direction of the wire rod 3 is bored in the metal rod 8, and a guide block 12, which is guided through the long hole 18, is connected to the jaw 10. .
The guide block 12 is provided with a threaded hole into which a threaded rod 14 extending longitudinally within the elongated hole 18 is externally fitted. This threaded rod 1
The upper and lower ends of 4 are supported by bearings on the upper and lower ends of a metal rod 8, and an engagement hole for a wrench is provided at the lower end. A groove is formed in the upper end of the threaded rod 14 in the circumferential direction, and a transverse pin 14' is provided in the fixed jaw 4, which engages the groove. Therefore, the threaded rod 14
#- can be freely rotated and its displacement in the axial direction is prevented.
A step is provided at the joint between the jaw 10 and the guide block 12, and a sliding surface 15 that slides on the side surface of the metal rod 8 is formed in this step. Therefore, when a wrench is inserted into the retaining hole on the lower end side of the threaded rod 14, the guide Glock 12 and the movable clamp 9 are moved in the axial direction of the threaded rod 14, but the sliding surface 15
The movable clamp 9 is prevented from rotating due to the contact between the metal bar and the side surface of the metal rod. Therefore, even when adjusting the vertical movement of the movable clamp 9 by operating a wrench, the position of one bottle 8 held by both clamps 5.9 is always maintained on the same plane.

It may be constructed as a movable clamp that is movable along the elongated hole 14 in the F-axis direction. In this case VcFi, the direction of the threading of the upper and lower halves of the threaded rod 14 is reversed, and the threaded holes in the block 12 of both clamps 5.9 are also correspondingly reverse threaded so that one part of the rod 14 is reverse threaded. It is preferable that both clamps 5.9 be configured to spirally move toward or away from each other by a rotational operation in this direction.

A wrench holding hole is formed at both ends of the metal rod, allowing the wrench to be operated from either the top or bottom of the metal rod. Furthermore,
By changing the clamp configuration as shown in FIGS. 4 and 5, the angle of the bisket 8 can be adjusted. In Figure 4,
An intermediate jaw pad or an intermediate washer 4' having an engagement groove for the pin 8 is inserted between both jaws 4 and 6 of the fixed clamp 5 by screws 7 and 6.
It allows you to freely rotate and play.

It becomes possible to perform arbitrary angle adjustment around the axis perpendicular to the rond axis of the pin 8. In FIG. 5, an intermediate jaw pad or intermediate washer 12 is interposed between the jaws 10 and 1.1 of the movable clamp 9, similar to the fixed clamp 5 described above. Therefore, the bottle holding section can rotate about the sliding surface 17GC between the block 12 and the intermediate washer 12', and in this case as well, the angle of the bottle 8 held by the movable clamp 9 can be adjusted as appropriate. can become.
