DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] To facilitate knee surgery, many knee replacement surgical braces have been developed to support the leg during surgery and adjust the knee's bending angle. Despite the assistance of surgical braces, the operation still requires the participation of a large number of medical workers to adjust the brace angle at any time. Generally, a knee replacement surgery requires the participation of at least four medical workers, which consumes excessive medical resources. Furthermore, during the operation, other auxiliary medical workers need to adjust the surgical brace according to the doctor's instructions, which is slow and prolongs the operation. It also places high demands on medical workers. Manual adjustment can result in large errors, or repeated adjustments are required to meet the requirements.

[0038] In order to solve the above problems, the present invention provides a knee replacement surgery bracket based on voice control, such as Figure 1 As shown, the surgical stand of the present invention includes a first angle adjustment mechanism 1 and a voice control unit;

[0039] Wherein, the first angle adjustment mechanism 1 is used to adjust the bending angle of the knee joint;

[0040] The voice control unit is used to receive voice information and control the first angle adjustment mechanism 1 to adjust the angle according to the voice information.

[0041] Among the existing knee replacement surgery brackets, except for the brackets that are adjusted directly by hand, most of the others are equipped with electric adjustment devices. This type of electric adjustment bracket can be equipped with a voice control unit to control the electric adjustment device through voice commands, and then use voice to control the angle adjustment of the bracket.

[0042] The present invention sets a voice control unit in the knee replacement surgical stent. During the operation, the stent can be controlled to automatically adjust directly through voice commands so that the knee joint reaches a suitable bending angle. The automatic adjustment has good stability and high precision, shortening the operation time. At the same time, the number of medical workers can be reduced to two to complete the operation, saving medical resources.

[0043] Generally, during knee replacement surgery, the patient lies on the operating table and the doctor is located on the outside of the patient. However, some operations during the operation need to be completed on the inside of the patient's knee joint. Therefore, it is still inconvenient to only adjust the angle of knee joint bending during the operation. For this reason, this embodiment also includes a second angle adjustment mechanism 2 for adjusting the angle of leg abduction; the voice control unit is also used to control the second angle adjustment mechanism 2 to adjust the angle according to voice information.

[0044] like Figure 2 As shown, in this embodiment, there are two angle adjustment mechanisms, namely a first angle adjustment mechanism 1 for adjusting the knee joint bending angle, and a second angle adjustment mechanism 2 for adjusting the leg abduction angle. Both angle adjustment mechanisms are controlled by a voice control unit, thereby realizing voice-controlled angle adjustment.

[0045] In a specific embodiment, a module structure of a voice control unit is provided, such as Figure 3 As shown, it includes a microcontroller, a sound pickup module, a first angle sensor and a second angle sensor, wherein,

[0046] A sound pickup module is used to pick up voice information and transmit the voice information to the microcontroller;

[0047] The first angle sensor is used to measure first angle information of the knee joint bending and transmit the first angle information to the microcontroller; wherein the bending angle of the knee joint refers to the angle between the thigh and the calf when the human body is lying flat and the legs are bent, and the first angle sensor is used to measure this angle.

[0048] The second angle sensor is used to measure the second angle information of the leg abduction and transmit the second angle information to the microcontroller; the angle of leg abduction refers to when the human body is lying flat, the legs are naturally straight, at this time the legs are considered to be centered, and the abduction angle is 0 degrees. When the legs are opened to both sides, the angle between the position of the opened legs and the centered position of the legs is the leg abduction angle, and the second angle sensor is used to measure this angle.

[0049] The microcontroller is used to generate a control signal according to the received voice signal, the first angle information and / or the second angle information, and control the first angle adjustment mechanism 1 and / or the second angle adjustment mechanism 2 to perform angle adjustment.

[0050] In the above embodiment, a specific structure of a voice control unit is provided for implementing a voice control function. During the adjustment process, a first angle sensor and a second angle sensor are used to measure the knee joint flexion angle and leg abduction angle before adjustment, respectively. The sound pickup module is used to receive voice commands. The microcontroller combines the voice commands and the angle information measured by the first angle sensor and / or the second angle sensor to generate a control signal to control the first angle adjustment mechanism 1 and / or the second angle adjustment mechanism 2 to perform angle adjustment, thereby implementing the function of voice-controlled automatic adjustment of the bracket.

[0051] After the voice pickup module picks up the voice information, it needs to be converted into text information so that the microcontroller can recognize it. In order to convert the voice information into text information, Figure 4 A modular structure for implementing a voice recognition function is provided. The voice control unit also includes a voice recognition module for converting captured voice information into text and transmitting it to a microcontroller. The microcontroller receives the recognized text and generates a control signal based on the text to control the first angle adjustment mechanism 1 and / or the second angle adjustment mechanism 2 to adjust their angles.

[0052] At present, the application of voice recognition is relatively widespread, and many businesses also provide online voice recognition services. Therefore, in order to realize voice recognition, you can also use an online voice recognition server. After the sound pickup module picks up the voice information, it uploads the voice information to the voice recognition server. The voice recognition server recognizes the voice and converts it into text information and sends it back to the microcontroller, which can then recognize it. Therefore, in order to realize the above voice recognition function, Figure 5Another module structure is provided, in which the voice control unit includes a communication module, which is used to send voice information to a cloud server, receive text information recognized by the cloud server, and transmit it to the microcontroller, wherein the communication module can be a wired or wireless communication module.

[0053] In the above embodiment, two specific structures for implementing the speech recognition function module are provided, which can be selected according to actual needs in actual applications.

[0054] In order to save energy, the voice control unit also includes a voice wake-up module. When the voice information received by the voice wake-up module successfully matches the preset voice information, the microcontroller is awakened. That is, when not working normally, except for the voice wake-up module, the other modules in the voice control unit are in sleep mode. At this time, the power consumption is extremely low. Only when the voice information received by the voice wake-up module successfully matches the preset voice information, the microcontroller is awakened, and then the other modules are awakened to turn on the voice control function. For example, the preset voice information can be set to "small bracket". When the voice wake-up module receives the voice information "small bracket", the voice wake-up module wakes up the microcontroller. At this time, a speaker module can also be configured in the voice wake-up module. When the microcontroller is awakened, it can reply "I'm here" through the speaker to remind the doctor that the voice control units have been awakened and can be adjusted.

[0055] In a specific embodiment, a specific structure of a first angle adjustment mechanism 1 is provided, such as Figure 6 As shown in FIG7 , the first angle adjustment mechanism 1 includes a fixed base 101, a first rocker arm 102, and a first electric push rod 103. One end of the first rocker arm 102 is hinged to the fixed base 101, while the base of the first electric push rod 103 is hinged to the fixed base 101. The telescopic end of the first electric push rod 103 is hinged to the other end of the first rocker arm 102, and the first electric push rod 103 is connected to a microcontroller. Furthermore, a fixing buckle 104 is provided on the side of the fixed base 101. During use, the fixing buckle 104 can be used to secure the surgical stand to the side of the operating table.

[0056] When in use, the surgical support is fixed to a suitable position on the side of the operating table by fixing the buckle 104, such as Figure 8 As shown, the patient lies flat on the operating table, the first rocker arm 102 is parallel to the patient's calf, and the first electric push rod 103 is extended and retracted, driving the first rocker arm 102 hinged thereto to swing up and down, that is, driving the thigh to swing up and down, thereby adjusting the angle of the knee joint bending.

[0057] In another specific embodiment, another specific structure of the first angle adjustment mechanism 1 is provided, such as Figure 9As shown in or 10, the first angle adjustment mechanism 1 includes a first slider 105, a second slider 106, a slide rail 107, a first rocker arm 102, a second rocker arm 108 and a first electric push rod 103; the first slider 105 and the second slider 106 are respectively slidably connected to the slide rail 107, one end of the first rocker arm 102 is hinged to the first slider 105, one end of the second rocker arm 108 is hinged to the second slider 106, the other end of the first rocker arm 102 is hinged to the other end of the second rocker arm 108, the base of the first electric push rod 103 is hinged to the first slider 105, and the telescopic end of the first electric push rod 103 is hinged to the second slider 106; the first electric push rod 103 is connected to the microcontroller.

[0058] During the specific setting, in order to ensure the stability of the overall structure, a first fixed base 109 and a second fixed base 1010 are set, the first slider 105 is fixed to the side of the first fixed base 109, the second slider 106 is fixed to the side of the second fixed base 1010, one end of the first rocker arm 102 is hinged to the first fixed base 109, one end of the second rocker arm 108 is hinged to the second fixed base 1010, the other end of the first rocker arm 102 is hinged to the other end of the second rocker arm 108, the base of the first electric push rod 103 is hinged to the first fixed base 109, and the telescopic end of the first electric push rod 103 is hinged to the second fixed base 1010.

[0059] When in use, the slide rail 107 is fixed to a suitable position on the side of the operating table, such as Figure 9 As shown, the patient lies flat on the operating table, the first rocker arm 102 is parallel to the patient's calf, and the first electric push rod 103 is extended and retracted, driving the first slider 105 and the second slider 106 to slide along the slide rail 107, driving the angle between the first rocker arm 102 and the second rocker arm 108 hinged thereto to change, thereby driving the angle between the upper and lower legs to change, and then achieving the adjustment of the knee joint bending angle.

[0060] The two embodiments described above provide two specific structures of the first angle adjustment mechanism 1. Both structures adjust the knee joint flexion angle by extending and retracting the electric push rod. After the doctor outputs a voice signal according to demand, the microcontroller recognizes the voice signal and sends a control signal to the first electric push rod 103, thereby adjusting the knee joint flexion angle.

[0061] In a specific embodiment, a specific structure of a second angle adjustment mechanism 2 is provided, such as Figure 6 and 9As shown, the second angle adjustment mechanism 2 includes a fixed rod 201, a swing arm 202, a swing rod 203, a leg support plate 204 and a locking motor 205. One end of the fixed rod 201 is fixed to one end of the first rocker arm 102, the other end of the fixed rod 201 is hinged to one end of the swing arm 202, one end of the swing rod 203 is hinged to the other end of the swing arm 202, and the other end of the swing rod 203 is slidably connected to the other end of the first rocker arm 102. Figure 6 As shown, the first rocker arm 102 is provided with a sliding hole, through which one end of the rocker arm 203 passes and can slide. A locking motor 205 is provided on the first rocker arm 102. When the locking motor is locked, it restricts the rocker arm 203 from sliding relative to the first rocker arm. In a specific configuration, the telescopic shaft of the locking motor 205 can be arranged to pass through the side wall of the sliding hole, so that the telescopic shaft of the locking motor 205 is perpendicular to the rocker arm 203. When locking is required, the telescopic shaft of the locking motor 205 extends and contacts the rocker arm 203, thereby restricting the rocker arm 203 from sliding relative to the first rocker arm. A leg support plate 204 is provided on one side of the rocker arm 202. During use, the base of the thigh is placed on this leg support plate 204.

[0062] The adjustment of the leg abduction angle is relatively simple, and the adjustment angle is small. During the operation, the doctor only needs to gently move the legs with his hands to achieve adjustment. Therefore, during the adjustment process, only voice commands are needed to control the locking motor 205 to release. After the adjustment is completed, the locking motor 205 can be controlled to lock through voice commands. At this time, the legs can be fixed at the appropriate abduction angle.

[0063] Of course, in other embodiments, automatic adjustment can also be achieved. This embodiment provides another specific structure of the second angle adjustment mechanism 2, such as Figure 7 and 10 As shown, it includes a fixed rod 201, a swing arm 202, a leg support plate 204 and a second electric push rod 206; one end of the fixed rod 201 is fixed to one end of the first rocker arm 102, and the other end of the fixed rod 201 is hinged to one end of the swing arm 202, the base of the second electric push rod 206 is fixed to the side of the first rocker arm 102, and the telescopic end of the second electric push rod 206 is hinged to the other end of the swing arm 202.

[0064] When in use, the patient's thigh root is placed on the leg support plate 204, and the doctor can control the extension and retraction of the second electric push rod 206 through voice commands, thereby adjusting the leg abduction angle.

[0065] The above four specific embodiments respectively provide two specific structures of the first angle adjustment mechanism 1 and two specific structures of the second angle adjustment mechanism 2. When used, they can be combined in pairs according to needs.

[0066] In the above two embodiments of the specific structure of the first angle adjustment mechanism 1, no leg fixing device is provided. Since both of the above two devices include two angle adjustment mechanisms for adjusting the legs, if only the first angle adjustment mechanism 1 is provided in the embodiment, the leg support plate 204 can be directly provided on the first rocker arm 102.

[0067] In a specific voice control process, for example, when a doctor needs to adjust the patient's knee joint to 45 degrees, the doctor sends a voice message "small bracket". At this time, after the voice wake-up module receives the voice message, it compares it with the preset voice message. If the comparison is successful, the microcontroller is awakened, and then other modules are awakened. At the same time, the voice control unit replies "I am here" to remind the doctor that it is currently in an adjustable state. The doctor can say the voice message "Adjust the knee joint to 45 degrees". After the sound pickup module receives the voice message, the voice recognition module recognizes the voice message as text and transmits it to the microcontroller. After the microcontroller recognizes the text message, it generates an adjustment instruction based on the current knee joint bending angle collected by the first angle sensor, controls the extension and retraction of the first electric push rod 103, and drives the first rocker arm 102 to swing, thereby adjusting the bending angle of the knee joint to 45 degrees. When the second angle adjustment structure is configured with a second electric push rod, the control process is the same. If the second angle adjustment mechanism 2 is equipped with a locking motor, the locking motor is usually in a locked state. When adjustment is required, only a voice command of "relax" is required. At this time, the angle of leg abduction can be adjusted by hand to reach a suitable position. At this time, the voice command "lock" can be said to lock the locking motor and complete the adjustment.

[0068] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the appended claims of the present invention.
