Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a composite distal radius fracture fixation mechanism. Background Art

[0002] Distal radius fracture is a common orthopedic injury that mostly occurs in the wrist. The distal radius refers to the part of the radius within 3 cm from the wrist joint surface, which is an important structure connecting the wrist bone and the arm. The fixation methods for distal radius fractures mainly include splint fixation, plaster fixation, external fixator fixation, etc. If the fracture symptoms are relatively mild and there is no obvious displacement, a splint can be used for fixation to ensure the stability of the fracture site and promote the recovery of the fracture. Plaster can also be used for fixation. If the patient's distal radius fracture symptoms are relatively severe, after splint fixation, the stability of the fracture site cannot meet the needs of fracture healing, and an external fixator is required for fixation.

[0003] Existing fixation mechanisms are mostly rigid and heavy, and can easily cause symptoms such as skin itching or pressure sores. They usually fix the forearm and wrist together, completely restricting the movement of the wrist and forearm. They are only suitable for severe fractures or the early postoperative period and are not suitable for use in the rehabilitation stage. Summary of the Invention

A first capacitive sensor 111 is arranged between the first outer sheath 11 and the first airbag lining 12, and a second capacitive sensor 211 is arranged between the second outer sheath 21 and the second airbag lining 22. The connecting assembly 3 includes a first side frame 31 and a second side frame 32. The first side frame 31 and the second side frame 32 are connected by a screw 35. The screw 35 passes through the second side frame 32 and is threadedly connected to the second side frame 32. A side opening 112 is provided on the wrist fixing assembly 1.

[0024] The wrist fixing component 1 and the arm fixing component 2 are split structures, and the two are connected together by a connecting component 3. The damping degree of the connecting component 3 is adjustable. By adjusting the damping degree of the connecting component 3, the required external force during the relative movement of the wrist fixing component 1 and the arm fixing component 2 is adjusted accordingly.

[0025] When wearing the wrist fixing assembly 1, the wrist fixing assembly 1 is directly put on the palm, the thumb passes through the side opening 112, and then the first air bag lining 12 is inflated through the first air pump 16, so that the first air pump 16 expands, causing the first air bag lining 12 to undergo corresponding elastic deformation, tightly adhere to the wrist skin, and fix the wrist. The expansion degree of the first air bag lining 12 is controlled by the inflation amount.

[0026] When wearing the arm fixation component 2, the arm fixation component 2 is directly put on the forearm, and then the second air pump 26 is used to inflate the second airbag lining 22, so that the second airbag lining 22 expands, prompting the second airbag lining 22 to undergo corresponding elastic deformation, and adhere closely to the skin of the forearm to fix the forearm.

[0027] The expansion degree of the first airbag lining 12 and the second airbag lining 22 are both controlled by the inflation volume of the air pump. The wrist fixing component 1 and the arm fixing component 2 are suitable for wearing and use by different groups of people and have good versatility. The first outer sheath 11 and the second outer sheath 21 are both made of medical-grade breathable fabrics, and the first airbag lining 12 and the second airbag lining 22 are both made of medical-grade silicone rubber, which is soft to the touch and highly comfortable when worn for a long time. It is not easy to cause skin itching, allergies, pressure sores, etc.

[0028] The first capacitive sensor 111 of the wrist fixation assembly 1 monitors the internal pressure of the first airbag lining 12 in real time. When the pressure of the first airbag lining 12 is lower than the set value, the first air pump 16 is started, and the first airbag lining 12 is inflated by the first air pump 16 until the pressure of the first airbag lining 12 returns to the set value. When the pressure of the first airbag lining 12 is higher than the set value, the first solenoid valve 18 is opened to deflate until the pressure of the first airbag lining 12 returns to the set value.

[0029] The second capacitive sensor 211 of the arm fixing assembly 2 monitors the internal pressure of the second airbag lining 22 in real time. When the pressure of the second airbag lining 22 is lower than the set value, the second air pump 26 is started to inflate the second airbag lining 22 through the second air pump 26 until the pressure of the second airbag lining 22 returns to the set value. When the pressure of the second airbag lining 22 is higher than the set value, the second solenoid valve 28 is opened to deflate until the pressure of the second airbag lining 22 returns to the set value.

The pressure value is preset through the second control panel 210. The second battery compartment 29 has a built-in battery assembly, and the battery assembly provides stable power support. The initial set pressure of the arm fixation assembly 2 can be adjusted according to the patient's weight and fracture type to adjust the pressure to the target value. The second control panel 210 includes a control unit for receiving a signal from a second capacitive sensor 211 and driving a second air pump 26 or a second solenoid valve 28 to realize automatic adjustment of the pressure of the arm fixation assembly 2.

[0032] In some examples, a first air intake pipe 15 and a first exhaust pipe 17 are provided on one side of the first airbag liner 12, one end of the first air intake pipe 15 is connected to the chamber of the first airbag liner 12, and the other end of the first air intake pipe 15 is connected to the first air pump 16, one end of the first exhaust pipe 17 is connected to the chamber of the first airbag liner 12, and the other end of the first exhaust pipe 17 is connected to the first solenoid valve 18.

[0033] When the first air pump 16 is working, air is inflated into the first airbag lining 12 through the first air inlet pipe 15 to increase the internal pressure of the first airbag lining 12. The internal pressure of the first airbag lining 12 is controlled by the inflation amount. When the first solenoid valve 18 is opened, the first exhaust pipe 17 is opened, and air is deflated through the first exhaust pipe 17 to reduce the internal pressure of the first airbag lining 12.

The internal pressure of the second airbag lining 22 is controlled by the inflation amount. When the second solenoid valve 28 is opened, the second exhaust pipe 27 is opened, and air is deflated through the second exhaust pipe 27 to reduce the internal pressure of the second airbag lining 22.

[0036] In some examples, one end of the first side frame 31 and one end of the second side frame 32 form a first connecting slot 33, and the other end of the first side frame 31 and the other end of the second side frame 32 form a second connecting slot 34.

A sliding rod 38 is provided on the fixed block 36, and the sliding rod 38 passes through the slider 37 and is slidably connected to the slider 37.

[0037] When the screw rod 35 is manually rotated, the slider 37 of the second side frame 32 can be driven to slide along the slide rod 38 to adjust the distance between the first side frame 31 and the second side frame 32. When the distance between the first side frame 31 and the second side frame 32 is reduced, the size of the first connecting slot 33 and the second connecting slot 34 is correspondingly reduced. When the distance between the first side frame 31 and the second side frame 32 is increased, the size of the first connecting slot 33 and the second connecting slot 34 is correspondingly increased. Both the first side frame 31 and the second side frame 32 have a certain elastic deformation capacity.

[0038] In some examples, a first connecting arm 13 is fixedly provided on one side of the first outer sheath 11 . The first connecting arm 13 is fixedly connected to a first connecting ball head 14 . The first connecting ball head 14 is embedded in the first connecting slot 33 .

[0039] When the size of the first connecting slot 33 decreases, the locking force applied to the first connecting ball head 14 increases, that is, the damping force between the first connecting ball head 14 and the first connecting slot 33 increases. When the size of the first connecting slot 33 increases, the locking force applied to the first connecting ball head 14 decreases, that is, the damping force between the first connecting ball head 14 and the first connecting slot 33 decreases.

[0040] In some examples, a second connecting arm 23 is fixedly provided on one side of the second outer sheath 21 . The second connecting arm 23 is fixedly connected to a second connecting ball head 24 . The second connecting ball head 24 is embedded in the second connecting slot 34 .

[0041] When the size of the second connecting slot 34 decreases, the locking force applied to the second connecting ball head 24 increases, that is, the damping force between the second connecting ball head 24 and the second connecting slot 34 increases. When the size of the second connecting slot 34 increases, the locking force applied to the second connecting ball head 24 decreases, that is, the damping force between the second connecting ball head 24 and the second connecting slot 34 decreases.

[0042] By adopting the above technical solutions: The pressure of the wrist fixation component 1 and the arm fixation component 2 is preset according to the patient's weight and fracture type. The capacitive sensor monitors the internal pressure of the airbag lining in real time. When the pressure of the airbag lining is lower than the set value, the air pump is started to inflate the airbag lining through the air pump until the pressure of the airbag lining returns to the set value. When the pressure of the airbag lining is higher than the set value, the solenoid valve is opened to deflate until the pressure of the airbag lining returns to the set value, thereby realizing automatic adjustment of the pressure of the wrist fixation component 1 and the arm fixation component 2, providing a stable environment for callus formation. The airbag lining has a soft touch and is very comfortable when worn for a long time. It is not easy to cause skin itching, allergies, pressure sores, etc.

[0043] The damping force of the connecting component 3 is adjustable. In the early stage of the fracture, the damping force of the connecting component 3 is adjusted to the maximum to limit the relative movement of the wrist fixing component 1 and the arm fixing component 2, thereby limiting the movement of the fracture site, avoiding displacement of the fracture ends, and providing a stable environment for callus formation. In the rehabilitation stage, according to actual usage needs, the damping force of the connecting component 3 is adjusted to an appropriate size. At this time, the wrist fixing component 1 can be driven by external force to undergo a certain deflection relative to the arm fixing component 2, and force is applied to drive the two to move relative to each other to achieve fracture rehabilitation.

The first outer sheath 11 is provided with multiple groups of slots, and the multiple groups of slots are each provided with a first steel plate 113.

[0045] In some examples, the second outer sheath 21 is provided with multiple groups of slots, each of which is provided with a second steel plate 212 .

[0046] Multiple sets of first steel plates 113 can be inserted into the first outer sheath 11 of the wrist fixation component 1, and multiple sets of second steel plates 212 can be inserted into the second outer sheath 21 of the arm fixation component 2. Through the multiple sets of first steel plates 113 and the multiple sets of second steel plates 212, the wrist fixation component 1 and the arm fixation component 2 are reinforced in the early stage of fracture recovery to provide mechanical support, enhance stability, help the fracture site maintain correct alignment and promote healing.

[0047] The lengths of the first steel plate 113 and the second steel plate 212 can be selectively set. In the early stage of fracture recovery, the first outer sheath 11 and the second outer sheath 21 can be connected by the steel plate to enhance stability. In the fracture rehabilitation stage, the steel plate can be pulled out and active rehabilitation can be performed by adjusting the damping force of the connecting component 3.
