Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a body position adjustment device for bone and joint surgery. Background Art

[0002] During bone and joint surgery, patients usually need to assume a specific body position under anesthesia to facilitate the doctor's operation. Due to the effect of anesthesia, patients will fall asleep and cannot actively control their bodies, so they need the help of medical staff to adjust and position their bodies. For patients with heavier weight, moving and adjusting their body positions is particularly difficult, and multiple medical staff need to collaborate to ensure the safety of the patients and that their body positions are correct.

[0003] At present, there are some surgical position adjustment devices on the market. For example, the patent with patent publication number CN111772970A discloses a fully automatic turning over, sitting up and translational nursing bed. The device divides the bed board into several partitions in the width direction. The adjacent two partitions are rotatably connected and can be folded up and down. In combination with the turning over drive device arranged at the bottom of the bed board, different turning over drive devices are responsible for the folding of different bed board partitions, thereby realizing the conversion of turning over posture; secondly, the rotation connection is realized by connecting rollers, and a conveyor belt is arranged on the adjacent connecting rollers. By setting a translation drive device, the conveyor belt can be rotated, thereby realizing the translation of the patient's body. Therefore, when using the fully automatic turning over, sitting up and translational nursing bed, the patient can adjust the sleeping position at will. However, the device uses a conveyor belt as the part that the user directly contacts for a long time, and the structure of the conveyor belt of the device makes it unable to provide good support when it contacts the patient, because the conveyor belt is in a mode in which the belt is tensioned by rollers at both ends, and the middle section of the belt is suspended, so the main weight of the patient's body will be shared by the transmission roller; and the device is a nursing bed, which does not require very high stability when in use, and does not need to consider the shaking and rolling of the belt; and now there is a need for a bone and joint surgery position adjustment device to solve the above technical problems. Under the premise of assisting the doctor in changing the patient's position through the conveyor belt, the patient can be fully supported during the operation, and the conveyor belt can be prevented from accidentally shaking, thereby ensuring the safety during the operation. Summary of the invention

[0004] In order to solve the above technical problems, the present invention designs a body position adjustment device for bone joint surgery, wherein the device does not need to lift the patient off the bed when the doctor helps the patient to lie sideways, the doctor only needs to extract the support pad, and lift the transmission belt through the cylinder to support the patient's back, and the transmission belt can roll left and right, and does not need to lift the patient off the bed when helping the patient to lie sideways, and only needs to lift one side of the patient's body while the transmission belt rolls, so that the patient can be changed from supine position to lateral position. If a prone position is required, the patient can be changed from lateral position to prone position by rolling the patient while continuing to slide the operating bed, and only one or two doctors need to cooperate to complete the body position change of lateral or prone position. In addition, for the good comfort and support of the bed during the operation, after the patient's body position is adjusted, the transmission belt can be lowered, and the support pad can be pushed back, so that the support pad can contact the patient for a long time, and provide sufficient support for the patient, to prevent the unstable shaking caused by the transmission belt directly supporting the patient during the operation.

[0005] In order to achieve the above technical effects, the present invention discloses a body position adjustment device for bone and joint surgery, comprising: a bed, an adjustment component, a base, a head pad, and a foot pad; the adjustment component is fixedly connected to the upper end of the base, and the bed frame is fixedly connected to the upper end of the adjustment component; The adjustment assembly includes: a bottom plate, a lifting mechanism, a conveyor belt, and a support column; one end of the support column is fixed to the upper surface of the bottom plate, and the other end is fixedly connected to the bed body; the lifting mechanism is fixedly arranged at the upper end of the bottom plate, and the conveyor belt is fixedly arranged at the upper end of the lifting mechanism; The lifting mechanism comprises: a cylinder, a scissor structure, and a lifting platform; the upper fixed end of the scissor structure is fixedly connected to the lifting platform, and the upper sliding end of the scissor structure is slidably matched with the lifting platform; the lower fixed end of the scissor structure is fixedly connected to the bottom plate, and the lower sliding end of the scissor structure is slidably connected to the bottom plate; the cylinder is fixedly mounted on the bottom plate, and the output end is fixedly connected to the lower sliding end of the scissor structure; the top of the lifting platform is fixedly connected to the conveyor belt; The bed body comprises: a bed frame and a support cushion; a plurality of hollow structures matching the support cushion are arranged in the bed frame, and an L-shaped slide groove is arranged inside the hollow structure; sliders are arranged on both sides of the support cushion, and a handle is arranged on one side of the support cushion perpendicular to and away from the slider; Furthermore, the conveyor belt comprises: a belt, a driving roller, a passive roller, a supporting roller, a connecting frame, and a motor; the driving roller and the supporting roller are rotatably arranged at both ends of the connecting frame, and a plurality of supporting rollers are rotatably arranged in the middle of the connecting frame, the belt is tensioned on the driving roller, the passive roller and the supporting roller, and the output shaft of the motor is fixedly connected to the driving roller; Furthermore, a plurality of buttons are provided on the side of the bottom plate, through which the lifting mechanism can be controlled to rise and fall, and the conveyor belt can be controlled to rotate forward and reverse; Further: the headrest is rotatably connected to the top side of the bed frame, and the footrest is rotatably connected to the bottom side of the bed frame; Furthermore: the base includes a driving column, a fixed column, and a pedestal, the fixed column is fixedly installed on the upper part of the pedestal, and the driving column is slidably installed inside the fixed column; the top of the driving column is fixedly connected to the bottom plate; the driving column drives the bottom plate to move up and down.

[0006] The beneficial effects of the present invention are: The device is provided with a liftable conveyor belt structure to assist doctors in helping patients change their positions without completely lifting the patients off the bed surface. During operation, the doctor only needs to pull out the support pad set inside the window frame, and then control the cylinder to drive the conveyor belt to be lifted up to form a support plane, which directly supports the patient's back, and the conveyor belt can roll left and right under the drive of the motor. When adjusting the patient to the side-lying position, the conveyor belt can be easily rolled and the patient's body on one side can be lifted at the same time, so as to achieve the transition from the supine position to the side-lying position. If the operation requires the patient to be in the prone position, the conveyor belt can be continued to be rolled, and the patient can be adjusted from the side-lying position to the prone position in coordination with the action of rolling the patient. Such assistance can greatly reduce the labor intensity of medical staff and minimize the discomfort that may be caused to the patient. In addition, the entire adjustment process can be completed with the cooperation of only one or two doctors. In addition, in order to ensure the support of the bed surface to the patient and the comfort of the patient during the operation, after the patient's position is adjusted, the doctor can control the conveyor belt to descend to a suitable position through a button and push the support pad back to its original position, making the entire operation process safer.

DETAILED DESCRIPTION

[0009] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1

[0010] The present invention discloses a body position adjustment device for bone and joint surgery, comprising: a bed body 1, an adjustment component 2, a base 3, a head pad 4, and a foot pad 5; the adjustment component 2 is fixedly connected to the upper end of the base 3, and the bed frame 101 is fixedly connected to the upper end of the adjustment component 2.

[0011] The adjustment assembly 2 includes: a bottom plate 201, a lifting mechanism 202, a conveyor belt 6, and a support column 204; one end of the support column 204 is fixed to the upper surface of the bottom plate 201, and the other end is fixedly connected to the bed body 1; the lifting mechanism 202 is fixedly arranged at the upper end of the bottom plate 201, and the conveyor belt is fixedly arranged at the upper end of the lifting mechanism 202; The lifting mechanism 202 includes: a cylinder 2013, a scissor structure, and a lifting platform 2012; the upper fixed end 208 of the scissor structure is fixedly connected to the lifting platform 2012, and the upper sliding end 209 of the scissor structure is slidably matched with the lifting platform 2012; the lower fixed end 2010 of the scissor structure is fixedly connected to the bottom plate 201, and the lower sliding end 2011 of the scissor structure is slidably connected to the bottom plate 201; The cylinder 2013 includes a cylinder seat 205, a cylinder body 206, and a push rod 207; the cylinder seat 205 is fixedly arranged at the upper end, the cylinder body 206 is rotatably mounted on the cylinder seat 205, the push rod 207 is slidably connected to the inside of the cylinder body 206, the push rod 207 is rotatably connected to the sliding end of the scissor structure, and the top of the lifting platform 2012 is fixedly connected to the conveyor belt 6; The lifting mechanism 202 uses the cylinder 2013 as a power source, and pushes the sliding end of the scissors structure 2014 through the push rod 207 inside it. When the push rod 207 moves outward, the lower sliding end 2012 of the scissors structure 2014 moves inward, and the lifting platform 2012 moves upward; when the push rod 207 moves inward, the lower sliding end 2012 of the scissors structure 2014 moves outward, and the lifting platform 2012 moves downward. Example 2

[0012] In this embodiment, the top of the lifting platform 2012 is fixedly connected to the conveyor belt 6, so the conveyor belt 6 can move synchronously with the lifting and lowering of the lifting platform 2012. The conveyor belt 6 includes: a belt 601, an active roller 602, a passive roller 603, a support roller 604, a connecting frame 605, and a motor 607; the active roller 602 and the support roller 604 are rotatably arranged at both ends of the connecting frame 605, and a plurality of support rollers 604 are rotatably arranged in the middle of the connecting frame 605; the belt 601 is tensioned on the active roller 602, the passive roller 603 and the support roller 604, and the motor 607 is fixedly connected to the active roller 602; The belt 601 has good wear resistance and tensile resistance, ensuring the long-term stable use of the conveyor belt 6. In addition, the belt 601 has a certain friction force to ensure that there will be no slipping when moving the patient. The support rollers 604 are evenly distributed on the connecting frame 605, ensuring the stability and uniformity of the belt 601 during operation, and preventing the belt 601 from deflecting or loosening during operation; During the operation, the conveyor belt 6 can drive the active roller 602 to rotate through the drive of the motor 607 according to the doctor's needs, thereby driving the belt 601 to move left or right. The running speed of the belt 601 can also be adjusted by the control of the motor 607 to meet the needs of different scenarios.

[0013] In order to ensure safety during use, a large gap is set on both sides of the conveyor belt 6 and the bed frame 101 to prevent foreign objects or even the body of the doctor or patient from being stuck between the edge of the conveyor belt 6 and the bed frame 101 due to operational errors, thereby reducing the occurrence of dangerous situations. Example 3

[0014] In this embodiment, the bed body 1 includes: a bed frame 101 and a support pad 102; a hollow structure matching the support pad 102 is provided in the bed frame 101, and a slide groove is provided inside the hollow structure; sliders 104 are provided on both sides of the support pad 102, and a handle 103 is provided on the top; the support pad 102 is slidably provided on the top of the bed frame 101, the middle of the bed frame 101, and the bottom of the bed frame 101; The support pad 102 is the part that contacts the patient for the longest time during the operation except for the bed frame 101. If there is no such part, the patient needs to contact the conveyor belt 6 for a long time. On the one hand, the conveyor belt 6 supports the belt 601 inside the conveyor belt 6 not on the plate surface but on the cylindrical surface, so it is not comfortable. In addition, high-precision operation is required during the operation. Since the torque resistance of the motor 607 of the conveyor belt 6 is limited, the belt 601 may roll during the operation, which is easy to cause danger. Therefore, the support pad 102 is needed to support the patient for a long time during the operation. Slide blocks 104 are fixedly provided on both sides of the support pad 102, and the support pad 102 is slidably installed in the L-shaped slide groove inside the bed frame 101 through the slide blocks 104. In a normal state, the support pad 102 is placed on the upper end of the conveyor belt 6. When the surgical position adjustment is required, the transmission belt is lowered first, and the slide block 104 of the support pad 102 will be lowered from the vertical end of the L-shaped slide groove to the horizontal end. The doctor can pull out the support pad 102 through the handle 103 at the end of the support pad 102, and then raise the conveyor belt 6 and support it to the patient's back; when the position adjustment is completed, the conveyor belt 6 is lowered, and the support pad 102 is pushed back through the handle 103. When the support pad 102 is pushed to the deepest part of the bed frame 101, the conveyor belt 6 is raised and pressed against the support pad 102, and the support pad 102 is pushed upward and stuck into the vertical groove of the L-shaped slide groove. Example 4

[0015] In this embodiment, a plurality of buttons 203 are provided on the side of the base plate 201, through which the doctor can control the rise and fall of the lifting mechanism 202 to adjust the height of the conveyor belt 6. In addition, the buttons 203 can also control the forward and reverse rotation of the conveyor belt 6 to assist the patient to turn left or right according to different needs. At the same time, the rotation speed of the conveyor belt 6 can be adjusted according to actual needs to better assist the operation. Example 5

[0016] In this embodiment, the head pad 4 and the foot pad 5 are rotatably connected to the top side and the bottom side of the bed frame 101, respectively, so that the doctor can easily adjust the angle and position of the head pad 4 and the foot pad 5. It is ensured that the head pad 4 and the foot pad 5 can always provide appropriate support for the patient. The head pad 4 and the foot pad 5 enable the patient to maintain a comfortable and stable position during the operation. It also reduces the patient's sliding caused by insufficient support during the operation, thereby reducing the risk of the operation and improving the accuracy of the operation. In addition, the head pad 4 and the foot pad 5 are made of soft and easy-to-clean materials to ensure that while providing support, the hygiene and cleanliness of the operating environment can also be maintained. Example 6

[0017] In this embodiment, the base 3 includes: a driving column 303, a fixing column 302 and a base 301; during the operation, the doctor can adjust the height of the bed 1 by operating the driving column 303 according to the patient's height, the surgical site and the surgical position. This height adjustment function enables the operating table to adapt to the needs of different patients and improves the flexibility and comfort of the operation. Example 7

[0018] In this embodiment, the working principle and process of the bone and joint surgery posture adjustment device are as follows: when the patient's posture needs to be adjusted, the transmission belt is first lowered, and at this time, the slider 104 of the support pad 102 will be lowered from the vertical end of the L-shaped slide groove into the horizontal end. The doctor can pull out the support pad 102 through the handle 103 at the end of the support pad 102, and then raise the conveyor belt 6 and support it to the patient's back; by starting the conveyor belt 6 and lifting one side of the patient's body at the same time, the patient can be adjusted from supine to upright. The patient can be placed in a prone position during surgery by rolling the conveyor belt 6. When the patient is in a prone position, the conveyor belt 6 can be lowered and the support pad 102 can be pushed back by the handle 103. When the support pad 102 is pushed to the deepest part of the bed frame 101, the conveyor belt 6 is raised and pressed against the support pad 102. The support pad 102 is pushed upward and inserted into the vertical groove of the L-shaped slide. At this time, the surgery can be continued.

[0019] In summary, the present invention is a device for adjusting the body position of bone and joint surgery, which can assist doctors to quickly adjust the patient's body position through a conveyor belt. Such assistance can greatly reduce the labor intensity of medical staff and minimize the discomfort that may be caused to patients. In addition, the entire adjustment process only requires the cooperation of one or two doctors to complete; in addition, in order to ensure the support of the bed surface to the patient and the comfort of the patient during the operation, after the patient's position is adjusted, the doctor can control the conveyor belt to descend to the appropriate position through buttons and push the support pad back to its original position, making the entire operation safer. The entire device is easy to operate, can significantly improve surgical efficiency, and at the same time reduce the labor intensity of medical staff and the risk of patients.
