Embodiment 1

[0027] Embodiment 1 is basically as follows:

[0028] A retractor for distal radius fractures such as figure 1 As shown, it includes a fixed plate 1, the right end of the fixed plate 1 is fixedly connected with an elbow rest 10, and the left end of the fixed plate 1 is connected with a pulling plate 2. The lower surface of the fixed plate 1 is provided with a groove 11 and is connected with the rotating assembly 3 .

[0029] Such as figure 2 As shown, the rotating assembly 3 includes a rotating rod 30, which is rotationally connected with the fixed plate 1. The rotating rod 30 includes a spline shaft 1 31, a threaded section 33 and a spline shaft 2 34, and the spline shaft 1 31 corresponds to the groove 1 11 positions are set, the spline shaft 1 31 is set with a spline sleeve 32, the threaded section 33 is located at the left end position of the groove 11, the fixed plate 1 is provided with a threaded hole 13, and the threaded section 33 can be threaded with the threaded ho...

Embodiment 2

[0037] The difference from Embodiment 1 is that, as Figure 4 As shown, a grip bar 22 is fixed on the upper surface of the pulling plate 2 . The patient can hold the grip bar 22 with his hand, and then fix his hand and the stretching plate 2 with a bandage 40 to improve the stretching stability.

Embodiment 3

[0039] The difference from implementation one is that, if Figure 5 As shown, a rotating plate 23 is detachably fixedly connected to the pulling plate 2 by bolts, and the rotating plate 23 is provided with a groove, and the palm of the patient can be put into the groove of the rotating plate 23 . During the pulling process, the doctor needs to make the palm and the arm form a certain angle according to the fracture situation. When the rotating plate 23 is installed, the rotating plate 23 can be fixedly installed at an angle with the middle line of the pulling plate 2. After the palm is put into the groove, the palm and the arm are at a certain angle.

Abstract

The present invention relates to the technical field of medical equipment, in particular to a retractor for distal radius fractures, comprising a fixed plate connected with a pulling plate, a rotating assembly is provided on the lower surface of the fixed plate, the rotating assembly includes a fixed The rotating rod connected to the plate rotates. The rotating rod includes a splined shaft 1 and a threaded section fixed to each other. It can be threadedly connected with the threaded hole; a spline sleeve is fixed with multiple bandages; the pulling plate is threadedly connected with fine-tuning bolts, and the fine-tuning bolts can offset the coaxial line of the rotating rod. This solution can pull the wrist and fix the palm of the arm, which solves the very inconvenient problem of fixing the arm and the palm in the prior art.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a retractor for distal radius fractures. Background technique [0002] Distal radius fractures are very common in fracture treatment. Generally speaking, distal radius fractures are wrist fractures, and the fracture occurs within 2 to 3 cm of the distal radius. Distal radius fractures need to be splinted until the bone recovers, and bone shortening occurs during the recovery process due to the pulling effect of the muscles, so continuous stretching of the wrist is required during the recovery process. At present, doctors give different pulling forces to the wrist according to different conditions of patients, and then fix the arms and palms on the splint respectively, but there are the following problems: it is very inconvenient for doctors to fix the arms and palms with bandages, and multiple Doctors work together, and the cooperation process requires a high degree of...
