Embodiment 1

[0057] Embodiment one: if Figure 1 to Figure 32 As shown, the combined unilateral double-arm multi-segment femoral fracture adjustable buckle bone compression fixator of this embodiment includes a pressure-regulating telescopic fixator, several steel nail fixing devices, a first support arm 10, a second support arm and Several reinforced clamps, the second support arm includes a left arm body 17-1 and a right arm body 17-2, the left arm body 17-1 is embedded in the left side of the pressure regulating telescopic fixer, and the right arm body 17-2 is embedded On the right side of the pressure regulating telescopic fixer, the connections between the left arm body 17-1 and the first support arm 10 and the right arm body 17-2 and the first support arm 10 are respectively established through reinforcement clamps, and the steel nail fixing device is installed On the first support arm or the second support arm.

[0058] Described pressure regulating telescopic fixer comprises press...

Embodiment 2

[0068] Embodiment two: if Figure 33 As shown, the present embodiment is combined into a unilateral double-arm multi-segmental femur fracture adjustable buckle pressurized external fixator, and the steel nail clips for externally fixing the fractures of the 3 ends of the femur are all combined with 4 adjustable square-head steel nail clips to connect each bone. The two steel nail tails of the section are fixed as described in Embodiment 1 of the pressurization method for each fracture section, and the feature is that the adjustable square head steel nail clip 4 can be transferred and corrected for fracture displacement.

Embodiment 3

[0069] Embodiment three: as Figure 34 As shown, the present embodiment is combined into a dual-arm multi-segment femur fracture with an adjustable buckle bone pressurized locking external fixator to externally fix the tail of the steel nail for the fracture of the 3 ends of the femur. The characteristics of the nail connection and clamping are that the speed of connecting the steel nails is fast, and the compression method of each fracture segment is the same as that described in the first embodiment.

Abstract

The invention relates to a fracture fixer, in particular to a combined single-side double-arm adjustable clamping bone pressurization fixer for multi-segmental femoral fracture and solves the problem that fracture is not easy to heal due to too big size, excess weight and poor flexibility of an existing external fixation support for fracture. The fixer comprises a pressure-adjustable retractable fixer and a plurality of steel nail fixing devices and is characterized by comprising a first supporting arm, a second supporting arm and a plurality of strengthening connection clamps, wherein the second supporting arm comprises a left arm body and a right arm body, the left arm body is embedded and inserted in the left side of the pressure-adjustable retractable fixer, the right arm body is embedded and inserted in the right side of the pressure-adjustable retractable fixer, the left arm body is connected with the first supporting arm through the strengthening connection clamps, the right arm body is connected with the first supporting arm through the strengthening connection clamps; the steel nail fixing devices are mounted on the first supporting arm or the second supporting arm. Steel nails can penetrate through each segment of the multi-segmental fractured femur for external fixation, bones on the fractured segments can be pressurized, physiological pressure stress on the femur is recovered, firm and stable external fixation can be realized through single-side double-arm locking, and the cure rate is increased.

Description

technical field [0001] The invention relates to a fracture fixer, in particular to a combined unilateral double-arm multi-segment femur fracture adjustable buckle bone pressurization fixer, which belongs to the technical field of external fixation brackets for long tubular fractures of extremities. Background technique [0002] The current external fixation brackets, such as ring external fixation brackets and multifunctional combination external fixation brackets, are bulky, inconvenient to carry, and inconvenient for postoperative care. The design of the universal ball neck at the end is thinner, the strength of the external fixation is weaker, and the presser is designed to be larger and longer, so that the steel nails on both sides of the broken bone are limited due to the large volume of the middle presser, and the steel nails It is inflexible, and it is impossible to wear steel nails against the broken end of the bone, and it is not in line with the principle of mechan...
