Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a distal radius fracture splint. Background Art

[0002] Distal radius fracture is a common type of fracture, usually caused by arm injury or fall caused by external force. The radius is a long bone in the human forearm, with the distal end located at the wrist, which is an important support connecting the wrist and hand. When a fracture occurs at the distal end of the radius, it will cause damage to the wrist and hand function, seriously affecting daily life and work. Distal radius fractures are currently mostly treated conservatively, through manual reduction, and after reduction, external fixation devices such as plaster, splints or braces are given in order to obtain stable contact between the fracture ends, prevent displacement of the fracture ends, and ultimately allow the fracture to heal. However, conservative treatment has the risk of re-displacement of the fracture ends, especially shortening displacement.

[0003] After searching, Chinese Patent No. 202011072864.6 discloses a retractor for maintaining the position of distal radius fracture without displacement, including a fixed splint, a wrist traction sleeve, a finger traction sleeve and a traction belt; the wrist traction sleeve is worn on the wrist and palm of the hand, and the finger traction sleeve is worn on the finger; the fixed splint is covered on the outside of the hand, forearm and elbow; the wrist traction sleeve and the finger traction sleeve are connected to the fixed splint through a traction belt, and traction is performed on the wrist or fingers.

[0004] The above-mentioned device uses a composite splint to maintain reduction through traction, but this treatment method is cumbersome to operate and the manufacturing materials are expensive. The bandages and finger cuffs squeeze the local tissue and skin for a long time, which is prone to local nerve and vascular diseases. In clinical operations, some people use intermittent finger cuff suspension traction to combat overlapping displacement, but this method is cumbersome to operate and has poor patient tolerance.

[0005] To this end, we propose a distal radius fracture splint. Utility Model Content

[0006] The purpose of the utility model is to provide a distal radius fracture splint to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a distal radius fracture splint, comprising two groups of dorsal palmar splints and two groups of ulnar radial splints, the dorsal palmar splints and the ulnar radial splints are both provided with aluminum plates inside, the aluminum plates are wrapped with polymer materials, the dorsal palmar splints and the ulnar radial splints are both divided into two groups of long and short, the two groups of dorsal palmar splints are used to clamp the palm and dorsal sides of the patient's arm, the two groups of ulnar radial splints are used to clamp the ulnar radial sides of the patient's arm, the outer surfaces of the dorsal palmar splints are both fixedly connected with belt loops, the bilateral surfaces of the ulnar radial splints are both fixedly connected with belt loops, the inside of the belt loops are used to insert matching binding belts, the ulnar radial splints are composed of a horizontal end and a bent end, the horizontal plane between the horizontal end and the bent end is distributed at an angle, the horizontal end is parallel to the patient's arm, the bent end faces the palm side or dorsal side, and a traction rod is installed between the bent ends of the two groups of ulnar radial splints.

[0008] Preferably, Velcro male and female surfaces are respectively provided at both ends of the binding belt.

[0009] Preferably, the bent end is bent toward the palm side or the dorsal side.

[0010] Preferably, a connecting hole is provided in the middle of the bent end, and both side sections of the traction rod are fixedly connected with a threaded shaft perpendicular to the cross section, and two groups of the threaded shafts are adapted to be inserted into the connecting holes in the middle of the bent ends on both sides, and the outer end surface of the threaded shaft is threadedly mounted with a butterfly nut.

[0011] Preferably, the surface of the bent end is provided with connecting holes which are linearly distributed at equal distances.

[0012] Preferably, the radial cross section of the traction rod is provided with an inclined surface.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. This solution uses the structural setting of the radial and ulnar splints to provide an extended bent end in front of the horizontal end, and the horizontal end and the bent end are designed to be horizontally angled, which further enables the device to adapt to palmar flexion (Colles fracture) or dorsal extension (Smith fracture) fixation when in use.

[0015] 2. In this scheme, a traction rod is installed between two sets of ulnar and radial splints. When the hand holds the traction rod, the splint as a whole moves proximally. The forearm is conical, and the forearm muscles bulge when the fist is clenched, so that the splint itself tends to move distally. The two sets of forces interact with each other, thereby generating a traction effect, pulling the fracture end, and thus preventing the fracture end from shifting.

[0016] 3. This solution uses a binding belt to pass through the belt loops on the outer surface of the palmar and radial splints to bind and fix the four splints into a whole, thereby preventing the radial splints from sliding under the binding belt when the patient exercises with a fist, thereby failing to achieve the purpose of traction.

[0023] Example

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] A distal radius fracture splint includes two groups of dorsal palmar splints 1 and two groups of ulnar and radial side splints 2. The dorsal palmar splints 1 and the radial and ulnar side splints 2 are both provided with aluminum plates 3 inside, and the aluminum plates are wrapped with polymer materials, so that the dorsal palmar splints 1 and the radial and ulnar side splints 2 can be accurately shaped according to the patient's body shape.

[0026] The outer surfaces of the two groups of palmar dorsal splints 1 are fixedly connected with belt loops 4, and the inner and outer surfaces of the two groups of ulnar radial splints 2 are fixedly connected with belt loops 4. After the two groups of palmar dorsal splints 1 and the two groups of ulnar radial splints 2 are wrapped around the patient's arm, a group of binding belts 5 are sequentially inserted into the four groups of belt loops 4 on the outer surfaces of the two groups of palmar dorsal splints 1 and the two groups of ulnar radial splints 2, so that the two groups of palmar dorsal splints 1 and the two groups of ulnar radial splints 2 are bound and fixed as one, thereby preventing the ulnar radial splints from sliding under the binding belts when the patient makes a fist. In addition, the two ends of the binding belt 5 are respectively provided with Velcro parent-child surfaces, so that after the binding belt 5 is bound to the device, it can be pasted and fixed by Velcro, so as to maintain the firmness of the device when worn, and the binding tightness can be adjusted by Velcro, so as to further improve the applicability of the device. Finally, the binding belt is used to strengthen the binding of the far and near middle sections of the splints to achieve a firm fixing effect.

[0027] The palmar dorsal splint 1 and the ulnar radial splint 2 are both provided in two pieces, long and short, and the splints are plasticized according to the fracture type of the patient.

[0028] If it is a Colles fracture, the longer distal end of the palmar dorsal splint 1 is bent toward the side without the strap loop 4, and the shorter distal end is bent toward the side with the strap loop 4; if it is a Smith fracture, the bending method is opposite to the above. The shorter piece of the ulnar radial splint 2 is bent from the angle between the horizontal end and the bent end. When bending, it should be noted that according to the left or right hand and the type of fracture, the bent end should be guaranteed to be bent toward the palm side (Colles fracture) or the dorsal side (Smith fracture) as required, which is used to fix the ulnar side of the arm. The longer piece of the ulnar radial splint 2 is also bent from the angle between the horizontal end and the bent end. When bending, it should be noted that according to the left or right hand and the type of fracture, the bent end should be guaranteed to be bent toward the palm side (Colles fracture) or the dorsal side (Smith fracture) as required, and the fracture angle should be smaller than that of the shorter piece, which is used to fix the radial side of the arm. At the same time, the bent end is plasticized into an arc with the apex facing outward according to the shape of the radial side of the patient's hand.

[0029] After the plasticity is completed, the two sets of palmar and dorsal splints 1 are placed on the palm and dorsal sides of the patient's arm respectively (if it is a Colles fracture, the longer one is on the dorsal side and the shorter one is on the ulnar side; if it is a Smith fracture, it is the opposite). The patient's arm is clamped and fixed in front and back positions. The shorter of the two sets of ulnar and radial splints 2 is placed on the ulnar side and the longer one is placed on the radial side. The ulnar and radial sides of the patient's arm are clamped and fixed. The direction of the bent end is determined according to the nature of the fracture (if it is a Colles fracture, the bent end faces the palm side; if it is a Smith fracture, it is the opposite). Finally, the patient's arm is fully wrapped and clamped to maintain the stability of the fracture end and prevent the fracture end from shifting. Finally, the patient's arm is fully wrapped and clamped to maintain the stability of the injured part.

[0030] The radial ulna splint 2 is composed of a horizontal end 21 and a bent end 22, and the horizontal end 21 and the bent end 22 are distributed at an angle in the horizontal plane. When the radial ulna splint 2 is worn, the horizontal end 21 is parallel to the patient's arm, and the bent end 22 is ensured to be bent toward the palm side (Colles fracture) or the dorsal side (Smith fracture) as required according to the difference between the left and right hands and the fracture type, so as to meet the requirements of fixation of distal radius fracture.

[0031] A connecting hole 23 is provided in the middle of the bent end 22, and a traction rod 6 is connected between the two sets of ulnar and radial splints 2 through the connecting hole 23. After the device further clamps and fixes the patient's forearm, when the patient performs fist-clenching exercises, the hand holds the traction rod 6 so that the splint as a whole moves toward the proximal end. The forearm is conical, and the forearm muscles bulge when the fist is clenched, so that the splint itself tends to move toward the distal end. The two sets of forces interact with each other, thereby generating a traction effect, pulling the fracture end, and preventing the fracture end from shifting.

[0032] The radial ulnar splint 2 needs to be shaped at the bent end 22 when in use (the splint needs to be plasticized according to the patient's fracture type, and the shorter piece of the radial ulnar splint is bent from the angle between the horizontal end and the bent end. When bending, it should be noted that according to the left or right hand and the fracture type, the bent end should be directed toward the palm side (Colles fracture) or the dorsal side (Smith fracture) as required, which is used for fixation of the ulnar side of the arm; the longer piece of the radial ulnar splint 2 is also bent from the angle between the horizontal end and the bent end. When bending, it should be noted that according to the left or right hand and the fracture type, the bent end should be directed toward the palm side (Colles fracture) or the dorsal side (Smith fracture) as required, and the fracture angle should be smaller than that of the shorter piece, which is used for fixation of the radial side of the arm. At the same time, the bent end is plasticized into an arc with the apex facing outward according to the shape of the radial side of the patient's hand). The cross sections at both ends of the traction rod 6 are fixedly connected with threaded shafts 7 perpendicular to the cross sections, and two sets of threaded shafts 7 are inserted into the connection holes 23 in the middle of the bent ends 22 on both sides to further realize the connection and installation of the traction rod 6 between the two ulnar and radial splints 2. At the same time, the outer end surface of the threaded shaft 7 is threadedly installed with a butterfly nut 8 to further realize the fixation of the traction rod 6 and the ulnar and radial splints 2 after connection and installation, thereby improving the structural firmness of the device and facilitating the disassembly operation of the device. At the same time, the middle of the bent end 22 is provided with connection holes 23 with equal distances and linear distribution, so that the traction rod 6 can be connected to different positions between the two sets of ulnar and radial splints 2 according to the size of the patient's hand, further facilitating the use of different patients and improving the applicability of the device.

[0033] In addition, the radial side section of the traction rod 6 is provided with an inclined surface 3 to meet the requirements for fixing the ulnar deviation of the distal radius fracture.

[0034] The device has a structure of the radial and ulnar splint 2, so that the front of the horizontal end 21 has an extended bent end 22, and the horizontal end 21 and the bent end 22 are designed to be horizontally angled, so that the device can be used toward the palm side (Colles fracture) or the dorsal side (Smith fracture) as required.

[0035] At the same time, a traction rod 6 is installed between the two groups of ulnar and radial splints 2. When the patient performs fisting exercises, when the hand holds the traction rod, the splint as a whole is displaced toward the proximal end. The forearm is conical, and the forearm muscles bulge when the fist is clenched, so that the splint itself has a tendency to displace toward the distal end. The two groups of forces interact with each other, thereby generating a traction effect, pulling the fracture end, thereby preventing the fracture end from shifting. At the same time, the traction rod 6 is installed between the two groups of ulnar and radial splints 2 through a threaded shaft 7 and a butterfly nut 8. The installation operation is simple and labor-saving. The radial section of the traction rod 6 is provided with an inclined surface 3, which is used to achieve the requirement of fixing the distal distal fracture ulnar deviation, and the ulnar edge is perpendicular to the traction rod 6.

[0036] The dorsal palmar splint 1 and the radial ulnar splint 2 are bound and fixed to form a whole by a binding belt 5 passing through the loop belt 4 on the surface thereof, thereby preventing the radial ulnar splint 2 from sliding under the binding belt 5 when the patient exercises with a fist, thereby failing to achieve a traction effect.

[0037] Through the above-mentioned structural setting, the device is cheap to manufacture, reusable, suitable for different patients through pre-bending, and easy to use. The disadvantage of the traditional splint fixation splint is used for traction to resist shortening and displacement of the fracture end, thereby improving the practicality of the device.
