Description

Technical Field

[0001] The invention relates to the medical field, and in particular to a magnetic dynamic tension orthopedic balloon splint. Background Art

[0002] Conservative treatment of fractures is a very suitable treatment method for simple fractures, especially for the elderly, children and patients with poor physical fitness or resistance to surgical treatment. Common fixation methods include splints, plaster, etc. Conservative treatment of simple fractures can relieve patients' pain and reduce economic costs, and is a good choice for patients with bone injuries. For example, for simple distal radius fractures, the orthopedic masterpiece "Campbell's Orthopedic Surgery" reported that a group of more than 20,000 patients with distal radius fractures in my country underwent conservative treatment of fractures and had a good prognosis. However, the treatise directly stated: They have no experience in conservative treatment of such fractures.

[0003] However, traditional splints and traditional plasters have common disadvantages, such as skin compression, no automatic regulation of the tightness of external fixation by external force, and no physical therapy effect; moreover, functional exercise or swelling reduction can lead to fracture displacement, and loss of reduction cannot be dynamically controlled.

[0004] At present, the improved fixation methods at home and abroad, such as plastic plaster and polymer splints, are only different in appearance or connection method and cannot solve the above problems in clinical practice.

[0005] Description of clinical problem:

[0006] A. Radius shortening deformity: Conservative treatment of distal radius fractures. No matter how the splint material is improved, it cannot provide axial traction at both ends of the fracture. The muscle traction itself can easily cause radial shortening deformity, and the fracture will eventually heal abnormally.

[0007] B Malunion of the distal radius: Dislocation of the distal radioulnar joint is caused, affecting the rotation, flexion and extension function of the patient's wrist joint, residual pain, and decreased wrist joint score and patient satisfaction

[0008] Many patients shorten and shift again after 2 weeks of plaster fixation, such as Figure 3 The ulnar head is shortened on the radial articular surface, resulting in distal radioulnar joint dislocation.

[0009] C Unplanned secondary surgery for patients with persistent chronic pain can cause adverse events. Summary of the invention

[0010] Purpose of the invention: To provide a better magnetic dynamic distraction orthopedic balloon splint. The specific purpose can be seen in the multiple substantial technical effects of the specific implementation part.

[0011] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0012] The magnetic dynamic distraction orthopedic balloon splint is characterized in that the splint comprises a back clamping part and a palm clamping part, each of which comprises two layers, namely an outer plate and an inner plate, the inner plate is a silicone inner plate, the outer plate is made of plastic, and further comprises a connecting shaft passing through the outer plate, the connecting shaft is connected to the silicone inner plate, and a magnet fixing part is above the connecting shaft; the magnet fixing part comprises a groove, in which a magnet can be placed, and further comprises a screw capable of fixing the magnet in the groove, and the screw passes through the side wall of the groove to squeeze the magnet;

[0013] The outer plates of the back clamping part and the palm clamping part respectively include arc-shaped parts on the upper side of the cross section, and the ends of the arc-shaped parts include butt joint parts, and the back clamping part and the palm clamping part can be fixed together through the butt joint parts;

[0014] The outer plates of the back clamping part and the palm clamping part respectively include an end arc part in the longitudinal section, and also include a pipeline passing through the end arc part, and the end of the pipeline is an air bag; the pipeline is connected through the air bag, and the pipeline is connected to the pressure gauge and the injection device through a tee.

[0015] A further technical solution of the present invention is that the airbag is a structure with one side larger and the other side smaller, that is, it includes a larger airbag side and a smaller airbag side, wherein the smaller airbag side is close to the planar portion of the back clamping portion and the palm clamping portion.

[0016] A further technical solution of the present invention is that the outer plate comprises a slide groove, and the connecting shaft passes through the slide groove and can move therein.

[0017] A further technical solution of the present invention is that the docking part is a magnet or a lock.

[0018] A further technical solution of the present invention is that the magnets comprise a series and the sizes of the magnets in the series are inconsistent.

[0019] A further technical solution of the present invention is that the injection device can pressurize the airbag, and the injection device is a water pump or an air pump.

[0020] 1. The present invention adopting the above technical solution has the following beneficial effects compared with the prior art: "magnetic dynamic orthopedic splint", which has not been reported in China.

[0021] 2. The contact parts are made of silicone with low surface tension and low surface energy to reduce skin pressure.

[0022] 3. Utilizing the biological effects of magnetism, the innovative design of the splint incorporates a dipole magnet. The dynamic weak magnetic field formed by the patient's dynamic functional exercise of fingers and muscle contraction provides power to promote bone healing.

[0023] 4. The innovative design solves the problem of splint tightness. The tightness of the splint is inversely proportional to the swelling, and the magnetic force is inversely proportional to the 3-4th power of the distance between the dipoles of the splint. The more obvious the swelling, the smaller the supporting force, achieving dynamic stability. The resulting dynamic weak magnetic field can promote physical therapy and repair of bone injuries.

[0024] 5. The sliding physical support placed on the top layer of the silicone splint is filled with dynamic magnetic poles and magnets to provide early distraction to reduce swelling and prevent shortening and displacement of the fracture. It can also dynamically adjust distraction or pressure in the axial position, similar to an accordion trajectory to promote fracture healing.

[0025] The innovative design of "Magnetic Dynamic Orthopedic Splint" is the result of multidisciplinary theoretical research and the invention of a new product. It not only has the reliable efficacy of conservative treatment external fixation and the advantage of no surgery, but also has the sliding distraction and pressure effects similar to transbone external fixators. It fundamentally solves the problem of conservative treatment of the above-mentioned fractures and avoids the pain of surgery to nail steel plates and external fixators penetrating bones.

[0033] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0034] This patent provides a variety of parallel solutions, and the different expressions are improved solutions or parallel solutions based on the basic solution. Each solution has its own unique characteristics.

[0035] The magnetic dynamic distraction orthopedic balloon splint is characterized in that the splint comprises a back clamping part and a palm clamping part, each of the back clamping part and the palm clamping part comprises two layers, namely an outer plate and an inner plate, the inner plate is a silicone inner plate, the outer plate is made of plastic, and further comprises a connecting shaft passing through the outer plate, the connecting shaft is connected to the silicone inner plate, and above the connecting shaft is a magnet fixing part 6; the magnet fixing part comprises a groove, in which a magnet can be placed, and further comprises a screw capable of fixing the magnet in the groove, and the screw passes through the side wall of the groove to squeeze the magnet;

[0036] The outer plates of the back clamping part and the palm clamping part respectively include arc-shaped parts on the upper side of the cross section, and the ends of the arc-shaped parts include butt joint parts, and the back clamping part and the palm clamping part can be fixed together through the butt joint parts;

[0037] The outer plates of the back clamping part and the palm clamping part respectively include an end arc portion in the longitudinal section, and also include a pipe passing through the end arc portion, and the end of the pipe is an air bag; the air bag is connected to the pipeline, and the pipeline is connected to the pressure gauge and the injection device through a tee. The substantial technical effect of the technical solution here and its implementation process are as follows: using multidisciplinary theoretical research, inventing a new product: it has both the reliable efficacy of conservative treatment external fixation and the advantage of no surgery, and has similar surgical "transbone external fixator"

[0038] The "sliding stretching and pressurizing" effect of the external fixator can be achieved by implanting a balloon inside, which can dynamically expand and adjust the skin pressure. The axial stretching can be performed dynamically by magnetic force, and the wrist palmar flexion angle can be adjusted externally, which fundamentally solves the problem of conservative treatment of the above fractures. In addition, the static or dynamic weak magnetic field generated can promote swelling reduction and fracture healing.

[0039] It can not only provide coronal magnetic force and magnetic field, but also provide axial traction and compression force through auxiliary reduction connection with the sliding device at the distal and proximal ends of the fracture. Combined with the actual clinical manifestations of patients, 8-24 hours after trauma is the period of continuous aggravation of swelling, and 3-5 days is the period of obvious swelling reduction. At this time, the patient is in great pain when the plaster is replaced or the fracture displacement is re-reset. If it is not replaced, the fracture position cannot be adjusted through the plaster. As the saying goes, "there is no water to put out the fire - anxiously", the reduction is lost and no intervention can be made, leaving regrets. This requires the use of relevant principles of magnetism and mechanics, combined with the medical principles mentioned above.

[0040] The back clamping portion described in the above statement is the back of the hand clamping portion.

[0041] The more obvious the swelling is, the smaller the applied force is, thus achieving dynamic stability. The stationary "static magnetic field" and the subsequent "dynamic weak magnetic field" produce the biological effect of the magnetic field, which can also promote the physical therapy and repair of bone injuries. The internal installation of a silicone sliding device connected to the external magnetic pole can also generate a dynamic magnetic field, which is powered by the patient's dynamic functional exercise of fingers and muscle contraction. At the same time, adjustable balloon devices are implanted in the silicone and at the fracture site. The tension is adjusted as needed, and the balloon at the fracture end is adjusted according to the reexamination of the X-ray to assist in maintaining the reduction or adjusting the palmar flexion angle (generally, it takes 2 weeks to adjust from the palmar flexion position to the neutral position), which is beneficial for the later functional exercise of the wrist joint.

[0042] The dynamic change of swelling causes the contact distance between the external fixator and the skin to change. At this time, the pre-designed direction and strength of the magnetic field force are inversely proportional to the 3-4th power of the designed splint magnetic pole distance, forming a reaction force. The silicone is connected to another set of dipole magnetic system, and the base is located at the belly of the patient's extensor tendon and flexor tendon. During the contraction exercise, a dynamic weak magnetic field is generated.

[0043] We know that magnetic therapy is recorded in ancient Chinese classics. Experiments have shown that magnetic field can regulate the biomagnetic field in the body, generate induced microcurrent, change cell membrane permeability, change the activity of certain enzymes, dilate blood vessels, and accelerate blood flow, thereby achieving auxiliary therapeutic effects such as pain relief and swelling reduction. It can accelerate bone healing and adjust the magnetic poles to provide power in the other direction of the fracture end to form stretching and pressure.

[0044] With this structure, the back clamping part and the palm clamping part are connected through the docking part, and the silicone installed inside, that is, the silicone inner plate, can be released from the body; the upper and lower magnets form a magnetic field. The end arc part is long and curved, and the front end of the palm is placed.

[0045] The outer plate includes a slide groove, and the connecting shaft passes through the slide groove and can move therein. The substantial technical effect of the technical solution and its implementation process are as follows: With this structure, the connecting shaft can drive the inner plate to slide, and further form traction with the front end of the palm. That is, it has the effect of "sliding stretching and pressurizing".

[0046] The airbag is a structure with one side larger and the other side smaller, that is, it includes a larger airbag side and a smaller airbag side, wherein the smaller airbag side is close to the planar portion of the back clamping portion and the palm clamping portion. The substantial technical effect of the technical solution herein and its implementation process are as follows: Using rare earth permanent magnets is a better choice. The Gaussian meter measures the magnetic field strength, and must not cause the magnetic lines of force that need to be effective in the two sets of magnetic pole systems to cancel each other out. The balloon is connected to a pressure measuring device to provide precise pressure and friction, and can also change the wrist flexion angle, dynamic changes, and the contact area of ​​the balloon size.

[0047] The docking part is a magnet or a lock. The substantial technical effect and implementation process of the technical solution of this invention are as follows: The lock can be the simplest implementation method, which can be two sheet structures docked together and connected by screws. The palmar and dorsal outer plates are slightly palmar flexed (such as Figure 2 As shown), the front view is slightly extended and embraced (as shown Figure 1 As shown), the anatomically fit forearm is well measured and connected physically and by a magnetic clasp.

[0048] The magnets described herein comprise a series and the sizes of the magnets in the series are not consistent, so the size can be adjusted.

[0049] The injection device can pressurize the airbag, and the injection device is a water pump or an air pump. The structure diagram here is not shown, and the pressurization method and structure are shown. Similar implementation methods are within the protection scope of this patent.

[0050] As a further improvement, combined with Figure 4 The outside of the airbag is also connected to the extrusion part through a connecting shaft. The outer plate is made of plastic and also includes a connecting shaft passing through the outer plate. The connecting shaft is connected to the outer wall of the airbag. Above the connecting shaft is a magnet fixing part. The magnet fixing part includes a groove in which a magnet can be placed. It also includes a screw that can fix the magnet in the groove. The screw passes through the side wall of the groove to squeeze the magnet. The design here is that the reaction force of the magnet at this place, i.e. the distal end of the clamp, will cause the inner splint to slide. If the fracture is shortened and displaced, the distance between the magnets will decrease, and the magnetic force generated will increase significantly. With the increase in reaction force, the shortening deformity of the fracture can be alleviated by sliding the interlayer splint.

[0051] As a further preference, pressure sensors can be attached to the back clamping part and the palm clamping part, and the pressure sensors are connected to the alarm part. The alarm device will sound an alarm when the force is within a certain range, which is convenient for accompanying and medical staff to deal with it in time; in addition, can the structure be designed to be quickly disassembled, which is convenient for dealing with emergencies. The pressure sensor can be replaced by a tension sensor.

[0052] It should be noted that the multiple modules of this patent are an integration of modules of the prior art and do not involve new modules.

[0053] Innovatively, each of the above effects exists independently, and a set of structures can be used to combine the above results.

[0054] The technical effect achieved by the above structure is clear. If the additional technical solution is not considered, the patent name can also be an orthopedic appliance. Some details are not shown in the figure.

[0055] It should be noted that the multiple solutions provided by this patent include the basic solution itself, which are independent of each other and do not restrict each other, but they can also be combined with each other without conflict to achieve multiple effects together.

[0056] The basic principle, main features and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the protection required.
