Description

Technical Field

[0001] This invention relates to the field of surgical scaffold technology, and more particularly to a pressure shaping device for surgical bone injuries. Background Technology

[0002] In the treatment of surgical orthopedic injuries, leg fractures are a common clinical injury. The fixation effect directly determines the quality of fracture healing and the patient's recovery process. Traditional Chinese medicine splint fixation technology, as a classic external fixation method with thousands of years of history, is widely used in the clinical treatment of closed leg fractures due to its advantages of convenient material sourcing, simple operation, non-invasiveness, and "dynamic and static combination" rehabilitation. Its core principle is to achieve stable fixation of the fracture ends through the rigid support of the splint, the restraining force of the straps, and the effect of the fixation pad, thus creating conditions for callus growth. However, traditional Chinese medicine splints have significant technical defects in the fixation of leg fractures. The core problem is that they cannot accurately adapt to the physiological curvature of the leg, resulting in uneven pressure and inadequate pressure transmission, which seriously affects the treatment effect. As a key weight-bearing part of the human body, the tibia and fibula have irregular shapes, and there are individual differences in the curvature of the inner and outer sides of the lower leg. Moreover, the curvature near the knee and ankle joints changes significantly. Traditional splints are mostly prefabricated straight boards or simple curved structures, and are mostly made of natural materials such as willow wood and bamboo. They have poor shaping flexibility and cannot achieve personalized fit according to the specific shape of the patient's leg. Moreover, during the recovery process, as the swelling of the injured area subsides, this misfit will become more and more obvious, which can easily lead to redisplacement of the fracture ends, malunion, and reduced fracture healing efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a pressure shaping device for surgical bone injuries. This invention uses an adjustable component to inflate the air bladder and conform it to the patient's leg, thus adapting to the physiological curvature of the leg. This avoids the difficulty of achieving a proper fit based on the specific shape of the patient's leg in existing technologies. A pressure sensor monitors the shaping pressure; when the sensor's reading falls below a threshold, the air bladder inflates further, ensuring that the air bladder remains in contact with the patient's leg and applies a certain shaping pressure. Compared to existing shaping methods that apply fixed pressure using straight plates or simple curved structures, this invention avoids the weakening of shaping pressure due to the reduction of swelling in the patient's leg.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a pressure shaping device for surgical bone injuries, comprising a first flipping block and a second flipping block, wherein the first flipping block is rotatably connected to the outer wall of the second flipping block via a rotating shaft, wherein a limiting component for changing the rotation angle of the second flipping block is provided on the first flipping block, and a telescopic component adapted to different leg lengths is provided on the outer wall of the first flipping block, wherein the patient can perform knee flexion movements by using the telescopic component and cooperating with the limiting component that releases the angle limiting state; A second electric push rod is fixedly installed on the outer wall of the second flipping block. A slide block is slidably connected to the outer wall of the second electric push rod. A locking component is provided on the slide block to lock its sliding position. A placement groove is provided on the middle outer wall of the slide block. Airbags are fixed on both inner walls of the placement groove. An adjustment component is provided inside the slide block to adjust the degree of airbag inflation. The adjustment component monitors the shaping pressure of the airbag and controls the inflation or contraction of the airbag according to the pressure feedback from the airbag. The adjustment component, in conjunction with the aforementioned limiting component, automatically releases the limiting state of the slide block when the airbag feedback pressure is too high.

[0005] Preferably, the adjustment assembly includes a pressure sensor fixedly installed on the inner wall of the cylinder, a third electric push rod fixedly installed at the sensing end of the pressure sensor, a piston fixedly installed on the outer wall of the output end of the third electric push rod, the edge of the piston being in close contact with the inner wall of the cylinder, and the air bladder being connected to the cylinder.

[0006] Preferably, the locking assembly includes two slide rails disposed on the outer wall of the second electric push rod, the slide block is slidably connected to the slide rails, a plurality of linearly arranged protrusions are disposed on the outer wall of the slide rails, a support rod extending towards the slide rails is disposed on the outer wall of the piston, a locking block is slidably connected to the outer wall of the end of the support rod away from the piston, and a spring is disposed between the locking block and the support rod.

[0007] Preferably, the two sections of the slide rail are respectively fixed to the outer wall of the output end and the fixed end of the second electric push rod, and are interlocked together along the extension and retraction direction of the second electric push rod.

[0008] Preferably, each of the two slide rails has a slot, and the outer wall of the slide block is provided with a locking block that slides into the slot.

[0009] Preferably, the limiting component includes a plurality of equidistant circumferentially distributed limiting holes on the outer wall of the second flip block, the limiting holes being distributed around the rotation center of the second flip block, a transmission chamber being provided inside the first flip block, a chuck being slidably connected inside the transmission chamber, a pin adapted to the limiting holes being provided on the outer wall of the chuck, and a bolt being rotatably connected to the outer wall of the first flip block by means of a threaded engagement, the end of the bolt extending into the transmission chamber and rotatably connected to the outer wall of the chuck.

[0010] Preferably, the telescopic assembly includes a first electric push rod fixed to the outer wall of the first flip block, an abutment block fixedly installed on the outer wall of the output end of the first electric push rod, and a baffle fixedly installed on the outer wall of the output end of the second electric push rod.

[0011] Preferably, the abutment block and the baffle abut against the patient's groin and foot respectively, and the outer walls of the abutment block and the baffle are provided with straps.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses an adjustable component to inflate the airbag and fit it against the patient's leg, thus adapting to the physiological curvature of the leg. This avoids the difficulty of achieving a proper fit based on the specific shape of the patient's leg in existing technologies. A pressure sensor monitors the shaping pressure, and when the pressure sensor's detection value is below a threshold range, the airbag inflates further to ensure that the airbag always remains in close contact with the patient's leg and applies a certain shaping pressure. Compared to existing shaping methods that apply fixed pressure using straight plates or simple curved structures, this invention avoids the weakening of shaping pressure due to the reduction of swelling in the patient's leg.

[0013] 2. This invention, through the locking component, allows the slide to slide along the second electric push rod under the cooperation of the slot and the locking block. This enables the slide to move the airbag directly to the injured area of ​​the leg, achieving a targeted pressure effect and avoiding the situation where the shaping pressure is dispersed and cannot be transmitted to the injured part of the patient's leg. When the slide moves to the target position, the piston is driven by the above-mentioned adjustment component to compress the internal space of the cylinder. The piston drives the locking block to move closer to the slide rail through the support rod. When the locking block abuts against the slide rail, the position of the slide is locked, realizing the fixation of the slide while the airbag is pressurized and corrected. This avoids the situation where the slide shakes and causes secondary injury to the patient. The operation is simple and quick.

[0014] 3. This invention, through the setting of limiting components and telescopic components, allows the angle between the first and second flipping blocks to be changed when shaping the patient's leg, adapting to the straight or bent state of the patient's leg. Rotating the bolt causes the bolt to push the chuck closer to the limiting hole, thereby causing the chuck to drive the pin to insert into the limiting hole, achieving the effect of locking the angle between the first and second flipping blocks. When using this device, the patient's foot abuts against the baffle, and the abutment block is locked at the root of the patient's thigh. Then, the device is fixed to the patient's leg with straps. Through the setting of the first and second electric push rods, this device can adapt to patients with different leg lengths. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] See Figures 1 to 7 As shown, a pressure shaping device for surgical bone injuries includes a first flipping block 1 and a second flipping block 2. The first flipping block 1 is rotatably connected to the outer wall of the second flipping block 2 via a rotating shaft. The first flipping block 1 is provided with a limiting component that changes the rotation angle of the second flipping block 2. The outer wall of the first flipping block 1 is provided with a telescopic component that adapts to different leg lengths. The patient can perform knee flexion movements by using the telescopic component and cooperating with the limiting component that releases the angle limiting state. A second electric push rod 22 is fixedly installed on the outer wall of the second flip block 2. A slide block 3 is slidably connected to the outer wall of the second electric push rod 22. A locking component is provided on the slide block 3 to lock the sliding position of the slide block 3. A placement groove 39 is provided on the middle outer wall of the slide block 3. Airbags 33 are fixed on both inner walls of the placement groove 39. An adjustment component is provided in the slide block 3 to adjust the degree of inflation of the airbags 33. The shaping pressure of the airbags 33 is monitored by the adjustment component, and the expansion or contraction of the airbags 33 is controlled according to the pressure feedback of the airbags 33. The adjustment component, together with the above-mentioned limiting component, automatically releases the limiting state of the slide block 3 when the pressure feedback of the airbags 33 is too large. The adjustment assembly includes a pressure sensor 36 fixedly mounted on the inner wall of the cylinder 32. A third electric push rod 35 is fixedly mounted on the sensing end of the pressure sensor 36. A piston 34 is fixedly mounted on the outer wall of the output end of the third electric push rod 35. The edge of the piston 34 is in close contact with the inner wall of the cylinder 32. The air bladder 33 is connected to the cylinder 32.

[0019] It should be noted that before operation, the third electric push rod 35 is in the retracted state, at which time the piston 34 is located on the side of the cylinder 32 away from the air bladder 33, and the air bladder 33 is in the retracted state.

[0020] When shaping the patient's leg, the injured part of the leg is placed in the placement groove 39 on the slide 3. The third electric push rod 35 is extended and pushed by the third electric push rod 35 to compress the internal space of the cylinder 32, so that the air in the cylinder 32 enters the airbag 33, thereby inflating the airbag 33 and conforming it to the patient's leg. Compared with the existing shaping method that uses natural materials such as willow wood and bamboo as splints, which is prone to causing redisplacement of the fracture ends and reducing the efficiency of fracture healing, the airbag 33 in this invention can undergo a certain degree of elastic deformation, thereby adapting to the physiological curvature of the leg and ensuring the patient's healing effect.

[0021] Meanwhile, the slide 3 is internally equipped with a controller and battery pack (not shown in the figure). The controller controls the extension and retraction of the third electric push rod 35 through the signal of the pressure sensor 36. The battery pack is a rechargeable battery used to provide power, enabling portable use and more flexible application scenarios. The airbag 33 applies a reverse force to the piston 34. This force is transmitted to the sensing end of the pressure sensor 36 through the third electric push rod 35, realizing the effect of monitoring the shaping pressure. When the detection value of the pressure sensor 36 is lower than the threshold range, it indicates that the leg swelling has subsided and the gap between the leg and the airbag 33 has increased. At this time, the control unit (not shown in the figure) controls the third electric push rod 35 to extend further, thereby causing the piston 34 to further compress the internal space of the cylinder 32, which in turn causes the airbag 33 to expand further, ensuring that the airbag 33 always stays in close contact with the patient's leg and applies a certain shaping pressure. Compared with the existing shaping method that applies fixed pressure through a straight plate or simple arc structure, this invention can avoid the weakening of shaping pressure due to the reduction of swelling in the patient's leg.

[0022] The locking assembly includes two slide rails 221 on the outer wall of the second electric push rod 22. The slide block 3 is slidably connected to the slide rails 221. Several linearly arranged protrusions 223 are provided on the outer wall of the slide rails 221. A support rod 37 extending towards the slide rails 221 is provided on the outer wall of the piston 34. A locking block 38 is slidably connected on the outer wall of the end of the support rod 37 away from the piston 34. A spring 381 is provided between the locking block 38 and the support rod 37. The two slide rails 221 are respectively fixed on the outer walls of the output end and the fixed end of the second electric push rod 22, and are inserted together with each other along the extension and retraction direction of the second electric push rod 22. A slot 222 is provided in both slide rails 221. A locking block 31 is provided on the outer wall of the slide block 3 and is slidably inserted into the slot 222.

[0023] It should be noted that, with the cooperation of the slot 222 and the block 31, the slide 3 can slide along the second electric push rod 22, thereby enabling the slide 3 to drive the airbag 33 directly to the injured area of ​​the leg, achieving the effect of fixed-point pressure, and avoiding the situation where the shaping pressure is dispersed and cannot be transmitted to the injured part of the patient's leg.

[0024] After the slide 3 moves to the target position, the piston 34 is driven by the above-mentioned adjustment component to compress the internal space of the cylinder 32. The piston 34 drives the locking block 38 to move closer to the slide rail 221 through the support rod 37. When the locking block 38 abuts against the slide rail 221, the position of the slide 3 is locked, so that the slide 3 is fixed at the same time as the airbag 33 is pressurized and corrected, avoiding the situation where the slide 3 shakes and causes secondary injury to the patient. The operation is simple and quick.

[0025] Furthermore, when the locking block 38 abuts against the slide rail 221, the support rod 37 compresses the spring 381, providing preload for the abutment between the locking block 38 and the protrusion 223. As the piston 34 further compresses the internal space of the cylinder 32, the support rod 37 further compresses the spring 381, thereby further increasing the preload and ensuring the reliability of the device.

[0026] In addition, the locking component can work with the adjustment component to automatically release when the slide 3 is impacted by external force due to bumping during patient movement. When the slide 3 is impacted by external force, the detection value of the pressure sensor 36 increases sharply. At this time, the third electric push rod 35 is controlled to retract. The third electric push rod 35 pulls the piston 34 away from the airbag 33, so that the air in the airbag 33 returns to the cylinder 32, relieving the pressure exerted by the airbag 33 on the patient's leg. At the same time, the piston 34 drives the locking block 38 away from the slide rail 221 through the support rod 37, so that the locking block 38 separates from the protrusion 223. This allows the slide 3 to slide along the second electric push rod 22 under the action of impact force, avoiding the impact force being directly transmitted to the patient's leg and causing secondary injury to the patient.

[0027] The limiting component includes several equidistant circumferentially distributed limiting holes 21 on the outer wall of the second flip block 2. The limiting holes 21 are distributed around the rotation center of the second flip block 2. A transmission chamber 11 is opened in the first flip block 1. A chuck 14 is slidably connected in the transmission chamber 11. A pin 141 adapted to the limiting holes 21 is provided on the outer wall of the chuck 14. A bolt 13 is rotatably connected to the outer wall of the first flip block 1 by thread engagement. The end of the bolt 13 extends into the transmission chamber 11 and is rotatably connected to the outer wall of the chuck 14. The telescopic assembly includes a first electric push rod 15 fixed to the outer wall of the first flip block 1. An abutment block 151 is fixedly installed on the outer wall of the output end of the first electric push rod 15. A baffle 23 is fixedly installed on the outer wall of the output end of the second electric push rod 22. The abutment block 151 and the baffle 23 abut against the patient's groin and foot, respectively. Straps 16 are provided on the outer walls of both the abutment block 151 and the baffle 23.

[0028] It should be noted that when shaping the patient's leg, the angle between the first flip block 1 and the second flip block 2 is changed to adapt to the straight or bent state of the patient's leg. The bolt 13 is rotated so that the bolt 13 pushes the chuck 14 closer to the limiting hole 21, thereby causing the chuck 14 to drive the pin 141 to be inserted into the limiting hole 21, thus achieving the effect of locking the angle between the first flip block 1 and the second flip block 2.

[0029] When using this device, the patient's foot is placed against the baffle 23, and the abutment block 151 is locked at the root of the patient's thigh. Then, the device is fixed to the patient's leg by the strap 16. With the first electric push rod 15 and the second electric push rod 22, the device can be adapted to patients with different leg lengths.

[0030] Furthermore, the extended first electric push rod 15 and second electric push rod 22 can support the patient's legs, simulating the effect of leg prosthesis auxiliary support. When the patient walks wearing this device, the baffle 23 abuts against the ground. Since the abutment block 151 is engaged at the root of the patient's thigh, the patient's affected limb does not directly bear weight and is in a protective support state. This prevents the patient's leg from bearing the weight of the body trunk, avoiding the situation in existing technologies where patients cannot move after wearing the device. This is beneficial to improving rehabilitation effects and enhancing the patient's self-care ability.

[0031] In addition, when the patient is undergoing rehabilitation training on his / her leg, the bolt 13 can be loosened so that the chuck 14 can drive the pin 141 to separate from the limiting hole 21, thereby releasing the locking of the angle between the first flip block 1 and the second flip block 2, allowing the patient to freely straighten or bend his / her leg, and avoiding muscle atrophy caused by prolonged fixation of the patient's leg.

[0032] Working principle: When shaping the patient's leg, the angle between the first flip block 1 and the second flip block 2 is changed to adapt to the straight or bent state of the patient's leg. The bolt 13 is rotated so that the bolt 13 pushes the chuck 14 closer to the limiting hole 21, thereby causing the chuck 14 to drive the pin 141 to be inserted into the limiting hole 21, so as to achieve the effect of locking the angle between the first flip block 1 and the second flip block 2. The patient's foot is brought into contact with the baffle 23, and the contact block 151 is locked at the root of the patient's thigh. The device is then fixed to the patient's leg by the strap 16. The device can be adapted to patients with different leg lengths by the first electric push rod 15 and the second electric push rod 22. Furthermore, the extended first electric push rod 15 and second electric push rod 22 can support the patient's leg, simulating the effect of leg prosthesis auxiliary support. When the patient walks wearing this device, the baffle 23 abuts against the ground. Because the abutment block 151 is engaged at the root of the patient's thigh, the patient's affected limb does not directly bear weight and is in a protective support state. This prevents the patient's leg from bearing the weight of the torso, avoiding the situation in existing technologies where patients cannot move after wearing the device. This is beneficial for improving rehabilitation effects and enhancing the patient's self-care ability. The injured leg is placed in the placement groove 39 on the slide 3. The third electric push rod 35 is extended, and the third electric push rod 35 pushes the piston 34 to compress the internal space of the cylinder 32, so that the air in the cylinder 32 enters the airbag 33, thereby causing the airbag 33 to inflate and fit against the patient's leg. Existing technology uses natural materials such as willow wood and bamboo as splints, which can easily lead to redisplacement of the fracture ends and reduce the efficiency of fracture healing. In this invention, the airbag 33 can undergo a certain degree of elastic deformation, thereby adapting to the physiological curvature of the leg and ensuring the healing effect of the patient. Simultaneously, the airbag 33 applies a reverse force to the piston 34. This force is transmitted to the sensing end of the pressure sensor 36 via the third electric push rod 35, thereby monitoring the shaping pressure. When the detection value of the pressure sensor 36 is lower than the threshold range, it indicates that the leg swelling has subsided and the gap between the leg and the airbag 33 has increased. At this time, the control unit (not shown in the figure) controls the third electric push rod 35 to extend further, thereby causing the piston 34 to further compress the internal space of the cylinder 32, which in turn causes the airbag 33 to expand further, ensuring that the airbag 33 always remains in close contact with the patient's leg and applies a certain shaping pressure. Compared with the existing shaping method that applies fixed pressure through a straight plate or simple arc structure, this invention can avoid the weakening of shaping pressure due to the reduction of swelling in the patient's leg. After the slide block 3 moves to the target position, the piston 34 is driven by the above-mentioned adjustment component to compress the internal space of the cylinder 32. The piston 34 drives the locking block 38 to move closer to the slide rail 221 through the support rod 37. When the locking block 38 abuts against the slide rail 221, the position of the slide block 3 is locked, so that the slide block 3 is fixed while the airbag 33 is pressurized and corrected, avoiding the situation where the slide block 3 shakes and causes secondary injury to the patient. The operation is simple and quick. In addition, when the locking block 38 abuts against the slide rail 221, the support rod 37 compresses the spring 381, providing pre-tightening force for the abutment between the locking block 38 and the protrusion 223. As the piston 34 further compresses the internal space of the cylinder 32, the support rod 37 further compresses the spring 381, thereby further increasing the pre-tightening force and ensuring the reliability of the device. In addition, the locking component can work with the adjustment component to automatically release when the slide 3 is impacted by external force due to bumping during patient movement. When the slide 3 is impacted by external force, the detection value of the pressure sensor 36 increases sharply. At this time, the third electric push rod 35 is controlled to retract. The third electric push rod 35 pulls the piston 34 away from the airbag 33, so that the air in the airbag 33 returns to the cylinder 32, relieving the pressure exerted by the airbag 33 on the patient's leg. At the same time, the piston 34 drives the locking block 38 away from the slide rail 221 through the support rod 37, so that the locking block 38 separates from the protrusion 223. This allows the slide 3 to slide along the second electric push rod 22 under the action of impact force, avoiding the impact force being directly transmitted to the patient's leg and causing secondary injury to the patient.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
