Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary treatment of bone tumors, and in particular relates to a bone fixing splint device. Background Art

[0002] The Chinese utility model patent application number is 2023215758327, which discloses an orthopedic fixation splint, which can be adapted to patients of different body sizes by adjusting the spacing between the first splint and the second splint. Specifically, the orthopedic fixation splint is suitable for patients with different leg circumference sizes.

[0003] In the daily treatment of fracture patients, for patients with different leg circumferences, adjustments can be made by appropriately tightening or loosening the bandages. The knee joints of some fracture patients still have a certain degree of mobility, and in the later stages of rehabilitation, they need to try to bend the knee joints appropriately for exercise purposes. However, the existing fixed splints are fixed in length, so after the knee joints are fixed, the patient's legs cannot be bent for exercise, and shortening the length of the splints does not provide a good positioning effect on the joints. Summary of the invention

[0004] The object of the present invention is to provide a bone fixation splint device, which can adjust the length of the front and rear knee splints while fixing both sides of the knee, thereby achieving the purpose of not affecting the patient's knee joint movement.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A bone fixation splint device comprises a main fixation plate attached to the outside of the knee, an auxiliary fixation plate attached to the inside of the knee, and a connecting strap, wherein the connecting strap is fixed to the main fixation plate and the auxiliary fixation plate in sequence. The bone fixation splint device also comprises a fixing splint assembly attached to the front and back sides of the knee, wherein the fixing splint assembly comprises a bottom plate, an extension plate, and a locking member for positioning the extension plate, wherein a sliding groove adapted to the telescopic sliding of the extension plate is provided in the middle of the bottom plate, and the bottom plate is fixed to the connecting strap.

[0007] The main fixing plate is in close contact with the outside of the knee, and the auxiliary fixing plate is in close contact with the inside of the knee, thereby clamping and fixing the left and right sides of the knee. There are two auxiliary fixing plates because they are close to the end of the connecting strap, which is convenient for adjustment according to the leg circumference of different patients. For example, if the patient's leg circumference is large, the connecting strap will be tied loosely, and at the same time, the distance between the two auxiliary fixing plates will also increase.

[0008] The fixed splint assembly is mainly set on the front and back sides of the knee. The extension plate contained in it can be adjusted in length according to different needs. For example, if the patient needs to be positioned in the early stage of surgery, the extension plate can be stretched upward to cover the knee. At this time, the knee is surrounded by the fixed splint, thereby achieving a supporting and fixing effect.

[0009] When the patient is in the recovery period or wants to move the knee joint, the extension plate can be inserted downward into the base plate, so that the entire knee joint is exposed, which makes it easier for the patient to bend or move.

[0010] Preferably, the locking member includes a sliding block and a bolt, a groove is provided at the side end of the base plate, the groove and the sliding groove are connected, the sliding block is fixed to the extension plate through a connecting block, the connecting block can slide freely in the groove, and the sliding block is provided with a threaded hole that passes through and is compatible with the bolt.

[0011] After the position of the extension plate is adjusted, the bolt is screwed into the threaded hole on the sliding block, and the end of the bolt is in close contact with the outer side of the bottom plate. Since the sliding block is fixed to the extension plate through the connecting block, when the end of the bolt is in close contact with the bottom plate, the extension plate will be in close contact with the wall of the sliding groove, thereby achieving fixation.

[0012] Preferably, the locking member further comprises a rotating knob, which is fixed to the end of the bolt facing away from the sliding block. The function of the rotating knob is to make it more convenient for the staff to apply force.

[0013] Preferably, the sliding block is provided with friction-increasing ribs.

[0014] When staff or patients push the sliding block, it is easy to slip. By adding friction-increasing ribs, the friction can be increased and the feel can be improved.

[0015] Preferably, a positioning strap is fixedly connected to the side end of the extension plate.

[0016] When the extension plate is extended, in order to make the end of the extension plate fit better with the leg skin, the positioning strap can make the extension plate gather more closely, so as to be more conducive to playing a supporting role and prevent the entire fixed splint from falling off.

[0017] Preferably, the thickness of the auxiliary fixing plate is 12 cm, and the thickness of the bottom plate is 5 cm.

[0018] Since the human knee joint is not a circle, but concave on both sides and convex on the knee joint, the thickness of the bottom plate is smaller than that of the auxiliary fixing plate and the main fixing plate.

[0019] Preferably, the connecting strap is made of cotton and linen, and the positioning strap is made of elastic material. The connecting strap is located at the calf, and the thickness of the calf of most patients does not vary much, while the positioning strap is located near the thigh. If it is made of elastic material, it is more conducive to adapting to the leg circumference and making adjustments.

[0020] Preferably, there are two fixing splint assemblies, which are respectively arranged on the front side and the back side of the knee.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. Through the cooperation of the base plate and the extension plate, it can meet the needs of patients at different stages and facilitate the patients to move their knee joints. At the same time, by adjusting the length of the extension plate, it can also meet the needs of patients of different heights, making the fixed splint more universal.
