Distal radius fracture wrist fixation protection tool

Abstract

The invention discloses a distal radius fracture wrist fixation protection tool. The distal radius fracture wrist fixation protection tool comprises a fore arm binding mechanism, a TDOF (Two-Degree of Freedom) mechanism and a palm binding mechanism which are sequentially connected in a fore arm direction, wherein the fore arm binding mechanism comprises an upper clamping plate for fore arm fixation, a rear restraint strap for fore arm fixation and a lower clamping plate for fore arm fixation, the rear restraint strap for fore arm fixation is fixed to the upper clamping plate for fore arm fixation, and the lower clamping plate for fore arm fixation is connected with the upper clamping plate for fore arm fixation by virtue of the restraint strap; the palm binding mechanism comprises a hand back fixation clamping plate, a palm fixation restraint strap arranged on the hand back fixation clamping plate and a palm fixation clamping plate connected with the hand back fixation clamping plate through the restraint strap; the TDOF mechanism comprises a rotary joint pedestal connected with the upper clamping plate for fore arm fixation, an ulnar-deviation radial-deviation rotary joint connected with the hand back fixation clamping plate, and a palm-inclination back-extending rotary joint arranged between the rotary joint pedestal and the ulnar-deviation radial-deviation rotary joint. The distal radius fracture wrist fixation protection tool is capable of replacing gypsum, achieving an effect of fixing a wrist of a patient suffering from distal radius fracture, and improving certain defects of gypsum fixation.

Description

technical field [0001] The invention relates to an external fixation protector for distal radius fractures, belonging to the technical field of external fixation medical devices. Background technique [0002] Distal radius fractures are extremely common clinically. At present, doctors will perform plaster external fixation on patients after traditional manual reduction. Plaster external fixation has the following disadvantages: 1. After the bone injury, the plaster is applied early, and the edema and hematoma have not yet floated up. As the swelling slowly rises, blisters may form, and if they rupture, ulceration and infection may occur; 2. 1. Swelling after bone injury, swelling does not subside, such as plaster fixation, as the swelling subsides slowly, there is space in the plaster, and the plaster cannot actually fix the patient's wrist; 3. Plaster is applied After that, it is difficult to observe the condition of the patient's wrist, and it is impossible to treat some...

Plaster external fixation has the following disadvantages: 1. After the bone injury, the plaster is applied early, and the edema and hematoma have not yet floated up. As the swelling slowly rises, blisters may form, and if they rupture, ulceration and infection may occur; 2. 1. Swelling after bone injury, swelling does not subside, such as plaster fixation, as the swelling subsides slowly, there is space in the plaster, and the plaster cannot actually fix the patient's wrist; 3. Plaster is applied After that, it is difficult to observe the condition of the patient's wrist, and it is impossible to treat some physical factors on the wrist fracture.

At present, the effect of manual rehabilitation training is good, but due to the high labor cost and the shortage of rehabilitation physician resources, many patients cannot obtain good rehabilitation training.
