Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a fixation splint for distal radius fractures. Background Technology
[0002] Distal radius fractures are the most common type of upper limb fracture. They typically refer to fractures within 3 cm of the distal end of the radius and are frequently seen in orthopedic outpatient and emergency departments, particularly in the elderly and young adults. The distal radius contributes to the formation of the wrist joint, and distal radius fractures are a common orthopedic trauma condition. In the event of an accident, people instinctively use their wrist for support, making it prone to injury. Traditional treatments for distal radius fractures often involve surgery, splinting, or external fixation with a wrist cast. Splinting is generally unstable, leading to unsatisfactory treatment outcomes and a higher risk of secondary injury, resulting in complications such as malunion and joint dysfunction. External fixation with a cast is not always reliable, frequently resulting in redisplacement of the fracture. Furthermore, the cast is heavy and prone to loosening and failure when exposed to moisture. Additionally, the cast requires simultaneous fixation of the wrist and adjacent fingers, significantly disrupting daily life and work. While surgical fixation offers more reliable fixation, it is still an invasive procedure, carrying the risk of pin tract infection, and is also more expensive, with lower patient compliance.
[0003] To correct fracture displacement and restore the length and palmar tilt of the radius, reduction of a radial fracture requires a palmar orientation. Current distal radius fracture fixation splints cannot provide proper positioning for the hand, and patients cannot effectively exercise their hands, resulting in slow recovery. Therefore, we propose a distal radius fracture fixation splint to address these issues. Utility Model Content
[0004] The purpose of this invention is to solve the problem that current distal radius fracture fixation splints cannot provide positioning for the palm of the hand, and patients' hands cannot be effectively exercised, resulting in a relatively slow recovery.
[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:
[0006] A fixation splint for distal radius fracture includes a main splint, multiple secondary splints, and a binding mechanism that can wrap and bind the main splint and multiple secondary splints to the fracture site of the injured person. The main splint is provided with a fixation post. When the binding mechanism binds the main splint and multiple secondary splints to the fracture site of the injured person, the fixation post is located on the palm side of the injured person.
[0007] Further specifying, the binding mechanism includes a strap, multiple pocket openings, and a locking assembly. The multiple pocket openings are sewn onto the strap, and the multiple pocket openings are elastic. The pocket openings and the strap together form a receiving cavity. The main splint and multiple auxiliary splints are inserted into the receiving cavity formed by the multiple pocket openings and the strap. The locking assembly is located on the strap. With this structural design, after the main splint and multiple auxiliary splints are inserted into the pocket openings, the locking assembly can work with the strap to bind the main splint and auxiliary splints to the fracture site of the injured person.
[0008] Further specifying, the locking assembly includes a male buckle fixed to the end of the strap and a female buckle movably mounted on the strap. The female buckle is a square buckle with a notch at one corner, and the strap has multiple hanging straps that fit the female buckle. This structural design allows the position of the square buckle to be adjusted according to the extension length of the strap end, so that the square buckle can be hooked onto the hanging straps. At this time, the male buckle, in conjunction with the female buckle, can lock the end of the strap.
[0009] Further, the main clamping plate has a through hole at one end for the fixing post to pass through, and a threaded hole communicating with the through hole is provided on the side of the main clamping plate. A locking bolt is threaded into the threaded hole. When the fixing post is inserted into the through hole, the end of the locking bolt abuts against the fixing post. All four corners of the main clamping plate are rounded. This structural design allows the fixing post to move within the through hole, facilitating adjustment of the extension length of the fixing post according to the size of the hand, and then locking the fixing post with the locking bolt.
[0010] Furthermore, an elastic balloon is fixedly installed at the end of the fixation post, and the surface of the elastic balloon is provided with anti-slip textured surfaces. This structural design, with the elastic balloon at the end of the fixation post, allows the injured hand to repeatedly knead the elastic balloon when the fixation post is located on the patient's palm, to perform rehabilitation training and accelerate recovery.
[0011] Furthermore, the four corners of the secondary splint are rounded, and a pull rope is fixedly installed at the end of the secondary splint. The secondary splint and the main splint are covered with sponge and cotton cloth from the inside out. This structural design, with the secondary splint and the main splint covered with sponge and cotton cloth, can improve the comfort of the injured arm.
[0012] The utility model adopting the above technical solution has the following advantages:
[0013] This utility model uses a binding mechanism to bind the main splint and the auxiliary splint to the radial fracture site of the injured person, so that the fixation post is located on the palm side of the injured person. The fixation post will limit the movement of the injured person's palm, which can correct the displacement of the fracture, restore the length and palmar tilt angle of the radius, and make the radial fracture site deviate towards the palm side during reduction. The structure is simple and easy to use. Attached Figure Description

[0027] like Figures 1-5As shown, this utility model discloses a distal radius fracture fixation splint, comprising a main splint 1, multiple auxiliary splints 2, and a binding mechanism 3 that can wrap and bind the main splint 1 and the multiple auxiliary splints 2 to the fracture site of the patient. The main splint 1 is provided with a fixation post 11, and the length of the main splint 1 is greater than the length of the auxiliary splints 2. The fixation post 11 is located at the end of the main splint 1 away from the pocket opening 32. When the binding mechanism 3 binds the main splint 1 and the multiple auxiliary splints 2 to the fracture site of the patient, the fixation post 11 is located on the palm side of the patient. An elastic balloon 5 is fixedly installed at the end of the fixation post 11. The surface of the elastic balloon 5 is provided with anti-slip ridges. When the fracture fixation splint is in use, the elastic balloon 5 is located in the palm of the patient, and the patient can repeatedly knead the elastic balloon 5 for rehabilitation training to accelerate the recovery speed.
[0028] The binding mechanism 3 includes a strap 31, multiple pocket openings 32, and a locking component. The multiple pocket openings 32 are sewn onto the strap 31 and are elastic. The pocket openings 32 and the strap 31 enclose a cavity. The main splint 1 and multiple auxiliary splints 2 are inserted into the cavity enclosed by the multiple pocket openings 32 and the strap 31. The number and spacing of the auxiliary splints 2 can be adjusted according to the thickness of the injured arm. The locking component is set on the strap 31.
[0029] The locking assembly includes a male buckle 4 fixed to the end of the strap 31 and a female buckle 41 movably mounted on the strap 31. The female buckle 41 is a square buckle with a notch at one corner. The strap 31 is provided with multiple hanging straps 42 that are adapted to the female buckle 41. By aligning the notch of the female buckle 41 with one end of the hanging strap 42, the female buckle 41 can be hung on the hanging strap 42. The hanging position can be flexibly adjusted according to the extension length of the strap 31, making it more convenient to use.
[0030] The main clamping plate 1 has a through hole 12 at its end for the fixing post 11 to pass through. The main clamping plate 1 has a threaded hole connected to the through hole 12 on its side. A locking bolt 13 is threaded into the threaded hole. When the fixing post 11 is inserted into the through hole 12, the end of the locking bolt 13 abuts against the fixing post 11. All four corners of the main clamping plate 1 are rounded.
[0031] The four corners of the secondary clamp plate 2 are rounded. A pull rope 21 is fixedly installed at the end of the secondary clamp plate 2. The secondary clamp plate 2 and the main clamp plate 1 are covered with sponge and cotton cloth from the inside to the outside.
[0032] The method of using this utility model is as follows:
[0033] When in use, insert the main splint 1 into the pocket 32 at the end of the strap 31 away from the male buckle 4. Then, select the appropriate number of auxiliary splints 2 according to the thickness of the injured arm. Then, position the fixing post 11 on the palm side of the injured arm and bind the main splint 1 and auxiliary splint 2 to the injured arm with the strap 31. After the end of the strap 31 is wrapped around the arm at least once, hang the female buckle 41 on the hanging strap 42 closest to the male buckle 4. Then the male buckle 4 and the female buckle 41 can be fastened together.
[0034] After the main splint 1 and the secondary splint 2 are bound to the injured arm by the strap 31, the extension length of the fixation post 11 on the main splint 1 can be adjusted so that the elastic balloon 5 is located on the palm side of the injured person. Then, the fixation post 11 is locked by the locking bolt 13. The injured person can perform rehabilitation training by repeatedly kneading the elastic balloon 5, which speeds up the recovery speed. The fixation post 11 has a limiting effect on the palm of the injured person, which can correct the displacement of the fracture, restore the length and palm tilt angle of the radius, and make the radial fracture of the injured person deviate to the palm side when it is reduced.
[0035] The above provides a detailed description of a distal radius fracture fixation splint provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
