Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a fixation frame after fracture surgery. Background Art

[0002] A fracture refers to the destruction of bone integrity or interruption of continuity. A fracture occurs when the force on a bone exceeds its maximum strength. Clinically, it often manifests as local pain, swelling, and movement disorders after trauma. Bone deformity, abnormal movement, and bone friction (feeling) are specific signs of fractures. After a fracture, it needs to be fixed with a fixation plate, plaster bandage, steel needle, intramedullary nail, screw, etc. to assist the healing of the fracture site.

[0003] For example, a postoperative fixation frame for fractures provided by patent application number CN202220727524.0 includes a strip plate, a first arc-shaped plate is fixedly installed on both sides of the upper front part of the strip plate, a number of evenly distributed first restraint belts are fixedly installed on one side of the strip plate, and a number of evenly distributed second restraint belts are fixedly installed on the other side of the strip plate, and grooves are respectively provided on both sides of the bottom surface of the strip plate, and clamping blocks are respectively installed in the grooves for sliding cooperation, and arc-shaped limit plates are respectively fixedly installed on the outer sides of the clamping blocks.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: Reference Figure 1-4 The postoperative fixation frame for fracture shown in the figure comprises a first fixing part 1 and a second fixing part 2 arranged in the same plane, and the first fixing part 1 and the second fixing part 2 are both provided with comb tooth structures that alternately cooperate with each other, and a limiting structure 3 is arranged between the comb tooth structure on the first fixing part 1 and the comb tooth structure on the second fixing part 2, wherein the limiting structure comprises a limiting slider 31 integrally arranged on the inner side of the comb tooth structure on the second fixing part 2, and a limiting groove 32 arranged on the inner side of the comb tooth structure on the first fixing part 1, and the limiting groove 32 is slidably matched with the limiting slider 31.

[0026] An adjusting assembly 4 is provided between the first fixing part 1 and the second fixing part 2 to adjust the overall length of the first fixing part 1 and the second fixing part 2, wherein the adjusting assembly 4 includes an adjusting screw 41 and an operating handle 42 fixedly connected to one end of the adjusting screw 41, the adjusting screw 41 is rotatably mounted on the first fixing part 1, and a screw hole 6 threadably matched with the adjusting screw 41 is provided on the second fixing part 2, and the operating handle 42 is located at an end of the adjusting screw 41 away from the second fixing part 2.

[0027] Through the first fixing part 1, the second fixing part 2 and the comb tooth structure alternately arranged between the two, under the sliding cooperation of the limiting slide groove 32 and the limiting slider 31, the first fixing part 1 and the second fixing part 2 can be expanded or merged by rotating the adjusting screw 41, thereby realizing the adjustment of the overall length of the first fixing part 1 and the second fixing part 2, which has better flexibility and stronger applicability.

[0028] The side end of the second fixing part 2 is fixedly connected with a fixing component 5. Specifically, the fixing component 5 includes a hook-surface Velcro 51 and a fleece-surface Velcro 52 bonded to each other. The hook-surface Velcro 51 is fixedly connected to one side end of the second fixing part 2 along its length direction, and the fleece-surface Velcro 52 is fixedly connected to the other side end of the second fixing part 2 along its length direction. The hook-surface Velcro 51 and the fleece-surface Velcro 52 are bonded to each other to stably fix the fixing frame on the finger after fracture surgery, and the operation is simple and convenient.

[0029] Furthermore, the upper end surfaces of the first fixing part 1 and the second fixing part 2 are fixedly connected with an arc-shaped fixing plate 7, and the axial direction of the arc-shaped fixing plate 7 is consistent with the length direction of the first fixing part 1 and the second fixing part 2. The arc-shaped fixing plate 7 can play a role of pre-fixation. When wearing, the arc-shaped fixing plate 7 can be used to first put the fixing frame as a whole on the finger after fracture surgery, so as to facilitate the bonding operation of the hook-side Velcro 51 and the fleece-side Velcro 52.
