Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, it relates to a fracture reduction and external fixation device based on traditional osteopathy and a fracture reduction method thereof. Background Art

[0002] Mongolian medicine is the summary of the Mongolian people's long-term struggle against diseases, and it gradually formed by absorbing the experiences of traditional Chinese medicine and Tibetan medicine. Mongolian medicine has a variety of diagnostic and treatment methods. Mongolian osteopathy is a characteristic therapy in Mongolian medicine and a natural therapy with miraculous effects that returns to nature in the world C0 school. With the osteopathic concept of active reduction, natural fixation, and functional healing, focusing on hand feeling function and ingenious techniques, mainly using splint fixation, spraying wine and pressing as characteristics, combined with scientific means, symptomatic medication, diet adjustment, functional exercise, sandbag squeezing, and traction.

[0003] In the actual operation process, for fractures, Mongolian medicine usually places pressure pads according to the direction of fracture displacement, then uses small splints for fixation, and finally uses inch bands for external fixation. This method has the following disadvantages:

[0004] 1. In the use process of the existing device, loosening or falling off may occur. Loosening or falling off will lose the fixing effect, affect the healing of the fracture, and may lead to complications such as fracture displacement and malunion.

[0005] 2. In the installation process of the existing external fixation device, the reduction mainly relies on the operator's experience, lacking precise preoperative planning, which may lead to inaccurate reduction, and some external fixation devices such as plaster fixation cannot be adjusted after fixation. Summary of the Invention

[0006] The purpose of the present invention is to provide a fracture reduction and external fixation device based on traditional osteopathy and a fracture reduction method thereof to solve the above technical problems.

[0007] The above technical purpose of the present invention is achieved through the following technical solutions: A fracture reduction and external fixation device based on traditional osteopathy, including a fracture site fixation structure and an anti-displacement structure, the fracture site fixation structure is detachably connected to the anti-displacement structure, the fracture site fixation structure includes splints and connecting bands, the splints are provided with 3 through grooves penetrating transversely, the connecting bands pass through the through grooves to connect 4 splints, the head of the connecting band is provided with a lock, the connecting band includes a soft part and a hard end, the soft part is fixedly connected to the lock, the tail of the connecting band is a hard end, and the inner side of the hard end is provided with anti-slip lines;

[0008] The anti-shift structure includes two connectors and a fixing knob used in cooperation with the connectors. A clip is fixedly connected to the top of each connector. A fixing strap is connected between the two clips. An adjusting strap is provided on one side of one of the clips away from the fixing strap, and an adjusting switch is provided on one side of the other clip away from the fixing strap. An angle adjuster is rotatably connected to the connector. A gasket is provided outside the connector, and the gasket is located between the angle adjuster and the fixing knob.

[0009] The present invention is further configured as: An insertion rod is connected between the fracture site fixing structure and the anti-shift structure. The fracture site fixing structure and the anti-shift structure are detachably connected through the insertion rod. External threads with opposite rotation directions are provided at both ends of the insertion rod.

[0010] The present invention is further configured as: The angle adjuster includes a driver. Rotating pieces are symmetrically arranged on both sides of the driver, and socket holes are provided on the rotating pieces.

[0011] The present invention is further configured as: The connector includes a connecting rod, a connecting roller, and a rotating shaft. The rotating shaft horizontally passes through the connecting roller, and the center of the rotating shaft is fixedly connected to the connecting rod. The clip is fixedly connected to the top of the connecting rod, and the socket hole is sleeved on the rotating shaft.

[0012] The present invention is further configured as: A threaded connection structure is provided on one side of the driver opposite to the extending direction of the rotating piece. The threaded connection structure is used to connect the insertion rod, and internal threads are provided inside the threaded connection structure.

[0013] The present invention is further configured as: A connection hole is provided at one end of the splint, and internal threads are provided in the connection hole.

[0014] The present invention is further configured as: A locking switch is provided on one side of the locker. The locking switch is fixedly connected to a transmission shaft. The transmission shaft horizontally penetrates the locker, and a blocking piece is fixedly connected to the part of the transmission shaft inside the locker.

[0015] By adopting the above technical solutions, in the present invention, the fracture site of the patient is fixed through the fracture site fixing structure. The fracture site fixing structure is mainly composed of four splints and connecting straps for connecting the splints. Three through slots are horizontally distributed on each splint, and are respectively distributed at both ends and the center of the splint. The connecting straps respectively pass through the three through slots to fix the splints. This design enables the splints to fit more closely to the patient's skin when the fracture site is fixed. Since the thicknesses of the patient's limbs are not likely to be uniform, during the process of fixing the splints, the tightness of the connecting straps can be adjusted respectively according to the positions of the three connecting straps, so that the inner diameter of the space surrounded by the splints is suitable for the affected limb of the patient.

[0016] In addition, traditional fixing devices often shift during use, resulting in secondary injury to the affected limb. Therefore, a displacement prevention structure is specially designed in the present invention. The displacement prevention structure in the present invention is connected to the fracture site fixing structure through an insertion rod, and insertion rods of different specifications can be selected for fixation according to different affected parts. Taking the fracture of the patient's forearm as an example, the fracture site fixing structure is fixed at the fracture position of the patient, while the displacement prevention structure is fixed on the upper arm. The connector is fixed near the elbow joint, preferably for the patient's comfort. Similarly, if the lower leg is fractured, the device can be fixed on the thigh, near the knee joint. The connector is engaged near the elbow joint or knee joint, and then cooperated with an adjustment strap for secondary fixation, which can effectively prevent the device from falling off or shifting.

[0017] After the patient has a fracture, although the affected limb should not move significantly, it is impossible not to move at all. Long-term immobility will cause muscle atrophy, and relevant muscle training needs to be increased after fracture recovery to resume use. Moreover, the severity of fractures varies among different patients, and patients can all appropriately move the affected limb without secondary injury. After analyzing the movable range in the early stage, the angle between the fracture site fixing structure and the displacement prevention structure can be adjusted through the angle adjuster. When manufacturing, angle scale lines can be set on the connector to facilitate medical staff to adjust to a suitable position, and then by tightening the fixing knob, the rotating piece and the gasket are closely fitted and cannot move, thereby realizing the fixation of the angle. This design fixes the angle at which the affected limb can move. On the one hand, it avoids secondary injury caused by the patient's own excessive movement of the affected limb, and on the other hand, since the moving angle is limited, the possibility of the device shifting due to movement will also be relatively reduced.

[0018] The present invention further provides a fracture reduction method for use in conjunction with the above external fixation device: The method steps are as follows:

[0019] S1. Patient information collection: After the patient is admitted to the hospital, imaging examinations are performed, and the relevant conditions are transmitted to the doctor. The length of the broken bone and the displacement condition of the fracture site of the patient are analyzed through an intelligent image analysis system;

[0020] S2. Formulating a treatment plan: Based on the relevant conditions of the fracture site given by the image analysis system, confirm the length of the splint required and the angle at which the affected limb can move, and then determine the fixing angle of the affected part;

[0021] S3. Fracture reduction and fixation in cooperation with the device: The doctor first manually reduces the affected part, then selects a suitable splint, appropriately grinds it or directly uses 3D printing to generate a splint suitable for the patient, and then performs fixation.

[0022] Further, the specific operation of fracture reduction in cooperation with the device in S3 is as follows:

[0023] (1) The doctor reduces the affected limb, then passes the connecting band through the through slots, sequentially connects the polished splints, places the connected splints under the patient's affected limb, so that the four splints are evenly distributed around the affected limb, and sequentially passes the tails of the upper, middle, and lower 3 connecting bands through the lockers to an appropriate position to achieve the fixation purpose.

[0024] (2) Connect the fracture site fixation structure and the anti-displacement structure through the insertion rod.

[0025] (3) Adjust the angle between the fracture site fixation structure and the anti-displacement structure through the angle adjuster, and fix the adjustment band on the adjustment switch to achieve the fixation of the anti-displacement structure.

[0026] By adopting the above technical solutions, the fracture site is reduced and fixed by the above method in cooperation with the device provided by the present invention, which can effectively solve the problem that traditional Mongolian medicine completely relies on the doctor's experience to analyze the fracture situation during the treatment of fractures.

[0027] In summary, the present invention has the following beneficial effects:

[0028] In the present invention, the fracture site is fixed through the fracture site fixation structure. The fracture site fixation structure is mainly composed of 4 splints and connecting bands for connecting the splints. Each splint is horizontally provided with 3 through slots, which are respectively distributed at both ends and the center of the splint. The connecting bands pass through the 3 through slots respectively to fix the splints. This design enables the splints to fit the patient's skin more closely when the fracture site is fixed. Since the thicknesses of the patient's limbs are not likely to be uniform, during the process of fixing the splints, the tightness of the connecting bands can be adjusted respectively according to the positions of the three connecting bands, so that the inner diameter of the space surrounded by the splints is suitable for the patient's affected limb.

[0029] In addition, the traditional fixing device often shifts during use, resulting in secondary injury to the affected limb. Therefore, the present invention specially designs an anti-displacement structure. The anti-displacement structure in the present invention is connected to the fracture site fixation structure through the insertion rod, and at the same time, different specifications of insertion rods can be selected for fixation according to different affected parts. Taking the fracture of the patient's forearm as an example, the fracture site fixation structure is fixed at the fracture position of the patient, while the anti-displacement structure is fixed on the upper arm. The connector is fixed near the elbow joint for the comfort of the patient. Similarly, if the calf is fractured, the device can be fixed on the thigh and fixed near the knee joint. The connector is clamped near the elbow joint or the knee joint, and then fixed secondly with the adjustment band, which can effectively prevent the device from falling off or shifting.

[0030] After a patient's fracture, although the affected limb should not be moved significantly, it is impossible to be completely immobile. Long-term inactivity will cause muscle atrophy. After the fracture is healed, relevant muscle training is required to resume use. In addition, the severity of fractures varies from patient to patient, and patients can move the affected limb appropriately without suffering secondary damage to the affected limb. After analyzing the range of motion in the early stage, the angle between the fracture site fixing structure and the anti-displacement structure can be adjusted through the angle adjuster. During manufacturing, the angle scale line can be set on the connector to facilitate medical staff to adjust to the appropriate position. Then, by tightening the fixing knob, the rotating piece and the gasket fit closely and cannot move, thereby achieving angle fixation. This design allows the angle at which the affected limb can move to be fixed. On the one hand, it avoids secondary damage caused by the patient's own unknowing movement of the affected limb. On the other hand, since the angle of movement is limited, the possibility of displacement of the device due to movement will also be relatively reduced.

[0031] By using the method provided by the present invention in combination with the device provided by the present invention to reduce and fix the fracture site, it is possible to effectively solve the problem that traditional Mongolian medicine completely relies on the doctor's experience to analyze the fracture condition during the treatment of fractures.

[0042] The following is further detailed description of the present invention in conjunction with the attached Figures 1-9 drawings.

[0043] Embodiment 1: An external fixation device for fracture reduction based on traditional osteopathy, including a fixing structure for the fracture site and an anti-displacement structure. The fixing structure for the fracture site is detachably connected to the anti-displacement structure. An insertion rod is connected between the fixing structure for the fracture site and the anti-displacement structure. The fixing structure for the fracture site and the anti-displacement structure are detachably connected through the insertion rod. The two ends of the insertion rod are provided with external threads with opposite rotation directions. The two sides of the insertion rod can be marked with relevant marks to identify which end is connected to the connecting hole and which end is connected to the threaded connection structure. For example, numbers, symbols, etc. can be marked at both ends for distinction. In addition, the insertion rod can be set with different lengths to be applicable to different fracture sites and patients with different body types.

[0044] The fixing structure for the fracture site includes a splint and a connecting band. One end of the splint is provided with a connecting hole, and the connecting hole is provided with internal threads. The splint is provided with 3 through slots penetrating transversely. The connecting band passes through the through slots to connect 4 splints. The head of the connecting band is provided with a locking device. One side of the locking device is provided with a locking switch. The locking switch is fixedly connected with a transmission shaft. The transmission shaft transversely penetrates the locking device. The part of the transmission shaft inside the locking device is fixedly connected with a blocking piece. The blocking piece forms an angle slanting backward and upward with the top inside the locking device, leaving enough length for the hard part to pass through. The connecting band includes a soft part and a hard end. The soft part is fixedly connected with the locking device. The tail of the connecting band is the hard end, and the inner side of the hard end is provided with anti-slip lines. The hard end is not made of a completely hard material. Materials such as cowhide or vegetable tanned leather with a certain elastic deformation ability and not particularly easy to bend can be selected, which can better turn through the through slot. When setting, the length of the hard end should also exceed the transverse width of the splint. When fixing, the blocking piece will not hinder the hard part from passing through when the hard part passes through the locking device, but when pulling it outwards after passing through, the locking switch needs to be rotated, otherwise the blocking piece will get stuck with the anti-slip lines and cannot move.

[0045] The anti-shift structure includes two connectors and a fixing knob used in cooperation with the connectors. A clip is fixedly connected to the top of each connector. A fixing strap is connected between the two clips. An adjusting strap is provided on one side of one of the clips away from the fixing strap, and an adjusting switch is provided on one side of the other clip away from the fixing strap. The connector is rotatably connected with an angle adjuster. A gasket is provided on the outer side of the connector. The gasket is made of rubber material and is located between the angle adjuster and the fixing knob.

[0046] The angle adjuster includes a driver. Rotating pieces are symmetrically arranged on both sides of the driver, and socket holes are provided on the rotating pieces. A threaded connection structure is provided on the side of the driver opposite to the extending direction of the rotating pieces. The threaded connection structure is used to connect an insertion rod, and internal threads are provided inside the threaded connection structure.

[0047] The connector includes a connecting rod, a connecting roller, and a rotating shaft. The rotating shaft horizontally passes through the connecting roller. The center of the rotating shaft is fixedly connected to the connecting rod. The connecting rod is fixedly connected with a clip at the top, and the socket hole is sleeved on the rotating shaft.

[0048] Example 2. A fracture reduction method based on traditional osteopathy

[0049] After a fracture patient is admitted to the hospital, first, the basic information of the patient is collected. At the same time, imaging examinations of the fracture site are also required. Currently, imaging examinations in major hospitals have realized real-time transmission of relevant situations to doctors. A large number of imaging images related to fractures are stored in the database of the intelligent image analysis system. Based on the data collection of a large number of influencing images and deep learning, when the imaging image of the patient's fracture site is transmitted, the system can analyze the length of the broken bone, the displacement situation, etc. of the patient.

[0050] Subsequently, a treatment plan is issued according to the results of the image analysis. This step makes osteopathy no longer rely on the experience of doctors, but more on the analysis of big data. Based on the relevant situation of the fracture site given by the image analysis system, confirm the length of the splint required, the angle at which the affected limb can move, and then determine the fixing angle of the affected area.

[0051] After the treatment plan is confirmed, the device provided by the present invention can be used for fracture reduction and fixation. The doctor first manually reduces the affected area, and then selects a suitable splint, grinds it appropriately or directly uses 3D printing to generate a splint suitable for the patient. The length, width, and arc of the splint need to be adjusted to a certain extent for different patients. What is directly 3D printed according to the patient's own situation should be the most suitable for the patient, but 3D printing takes a certain amount of time, and not all hospitals have the ability to 3D print relevant instruments for patients. Therefore, splints of different specifications can also be produced, and the doctor can grind them appropriately according to the actual situation.

[0052] When fixing, first pass the connecting belt through the through groove, sequentially connect the polished splints, place the connected splints under the affected limb of the patient, so that the four splints are evenly distributed around the affected limb, and sequentially pass the tails of the upper, middle and lower 3 connecting belts through the lock to an appropriate position to achieve the fixing purpose. Subsequently, connect the fracture site fixing structure and the anti-displacement structure through the insertion rod. Taking the fracture of the patient's forearm as an example, the fracture site fixing structure is fixed at the fracture position of the patient, while the anti-displacement structure is fixed on the upper arm. Among them, the connector is fixed near the elbow joint for the comfort of the patient. After the patient fractures, although the affected limb should not be moved greatly, it is impossible not to move at all. Long-term immobility will cause muscle atrophy, and relevant muscle training is still needed after fracture recovery to restore use. And the severity of fractures of different patients varies. Patients can appropriately move the affected limb without secondary injury to the affected limb. After analyzing the movable range in the early stage, the angle between the fracture site fixing structure and the anti-displacement structure can be adjusted through the angle adjuster. When manufacturing, angle scale lines can be set on the connector to facilitate medical staff to adjust to an appropriate position. Subsequently, by tightening the fixing knob, the rotating piece and the gasket are closely attached and cannot move, thereby realizing the fixation of the angle. In addition, an anti-slip structure can be set on the gasket to increase the friction between the two. Finally, the adjusting belt is fixed on the adjusting switch to achieve the fixation of the anti-displacement structure.

[0053] This specific embodiment is only an interpretation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions according to needs, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
