Description

Technical Field

[0001] The invention relates to the field of surgical equipment, and more specifically to a handpiece head and an intelligent variable speed micro-power system for orthopedic surgery. Background Art

[0002] The existing micro-power systems used for bone surgery internationally mainly use surgical equipment driven by micro-motors. The requirements for the speed of the micro-motor vary depending on the actual surgical tools and the hardness of the bones. The existing micro-power systems control the output power speed through the power console. Some micro-power systems can achieve fine-tuning of the speed through foot-controlled stepless speed regulation after outputting the highest speed. However, these micro-power systems have only one highest speed and cannot be selected for bones of different hardness.

[0003] For example, the Chinese invention patent application disclosure specification CN1931103A discloses a multifunctional surgical device for orthopedics, which includes a host, a motor movement, a tool handle and a tool head. The control system of the host is preset with multiple sets of motor movement drive parameters with different speeds. When different tool handles are installed on the motor movement, the Hall linear sensor on the motor movement obtains the identification signal of the identifier composed of magnetic rings and magnets on different tool handles, and transmits the identification signal to the host through the signal transmission line. The host automatically determines the specific driving parameters according to the different identification signals to drive the motor movement to produce different speeds. The advantage of this device is that during the operation, the doctor operating the tool of the present invention only needs to plug the tool handle of the corresponding function into the motor movement according to the needs of the operation, and install the corresponding tool head. There is no need to adjust the host. The host automatically identifies the inserted tool handle and provides the corresponding driving power supply, and the operation is very simple. However, each working handle of the device has only one maximum speed. When the working handle is installed on the motor movement, its maximum speed is directly selected. The doctor and the device cannot change the maximum speed during the process. The speed can only be fine-tuned by the foot-controlled stepless speed regulation. In this way, the maximum speed cannot be selected and adjusted for bones of different hardness. In addition, based on actual operating habits and operating experience, different doctors have different speed requirements for different tool heads while ensuring safety. The maximum speed is directly selected, making it impossible for the tool head to adapt to different doctors, which also directly affects the progress and effect of the operation. Summary of the invention

[0004] The present invention aims to overcome the problem that there is only one maximum speed in the above-mentioned prior art, and provides a handpiece head for orthopedic surgery. At least two barcodes representing different maximum speeds are printed on the shell of the handpiece head. The barcode is used to control the speed of the handpiece head. Multiple maximum speeds can be freely selected, thereby improving the flexibility of selecting the maximum speed of the drive head.

[0005] Another problem to be solved by the present invention is that bones of different hardness have different requirements for the maximum speed of the tool head, and different doctors have different speed requirements for different tool heads. By integrating the advantages of different surgical tools in the prior art, an intelligent variable speed micro-power system for orthopedic surgery is provided. The barcode is aligned with the barcode scanner by rotating the mobile phone head, and the barcode scanner scans and transmits it to the host. The host controls the rotation of the motor, and the maximum speed can be freely changed, thereby improving the flexibility and applicability of the selection of the maximum speed of the tool head.

[0006] The present invention achieves its object through the following schemes.

[0007] The present invention provides a mobile phone head for orthopedic surgery, including a motor, a housing and a driving head. The motor is installed in the housing, and the speed of the motor is adjustable. The driving head is installed at the front end of the housing and connected to the motor. The motor is used to control the rotation of the driving head. The housing is printed with at least two barcodes for being scanned by a barcode scanner, each barcode represents a maximum motor speed, and each barcode is used to control a maximum speed of the motor. Other barcodes of maximum speeds are stored in a speed database and can be extracted and used by a barcode scanner at any time. The barcode is aligned with the scanning gun by rotating the mobile phone head. After the barcode scanner scans the barcode, the maximum speed represented by the barcode is transmitted to the host, and the host controls the motor to rotate to the required speed. The mobile phone head has a variety of maximum speeds for doctors to choose freely, which improves the flexibility of selection.

[0008] Preferably, the shell is cylindrical, and at least two adjacent barcodes are distributed in a staggered step-like manner along the axial direction of the shell.

[0009] Preferably, the shell is a cube or a triangular prism, and different barcodes are distributed on different prism surfaces.

[0010] Preferably, the shell is a pentagonal prism or a cylinder with more than five prisms, and different barcodes are distributed at intervals on different prism surfaces.

[0011] Preferably, when the number of the barcodes is greater than the prism surface, the distance between the barcodes distributed on the same prism surface is greater than or equal to 4 centimeters.

[0012] After adopting the barcode with the above-mentioned structural distribution, the problem of mis-scanning can be avoided when scanning the barcode with a barcode scanner.

[0013] Preferably, the barcode is a laser barcode, which is composed of notches of different widths, and the notches can be filled with pigment.

[0014] The present invention also provides a micro-power system with intelligent speed change for orthopedic surgery, the structure of which includes:

[0015] A host computer for controlling the motor, a barcode scanner connected to the host computer, and a mobile phone head equipped with the motor, the mobile phone head is connected to the host computer.

[0016] With the micro-power system with the above structure, the doctor rotates the head of the mobile phone to select the required barcode, and then aligns the barcode with the scanner. After the scanner scans the barcode on the head of the mobile phone, the scanner sends a signal to the host. After receiving the signal, the host controls the motor in the mobile phone head to rotate to the maximum speed represented by the corresponding barcode. The system has a variety of maximum speeds for doctors to choose from, which improves the flexibility of selecting the maximum speed of the tool head and is easy to operate. In addition, the doctor only needs to rotate the head of the mobile phone to select the barcode, and the speed can be adjusted by scanning with the scanner. The doctor does not need to operate any other equipment except the mobile phone head. The mobile phone head can be disinfected, and the scanner gun is difficult to disinfect as a whole in actual applications, ensuring the safety during the operation.

[0017] Preferably, the mobile phone head has a controller connected to the motor, the controller is used to control the rotation speed of the motor, and the mobile phone head is wirelessly connected to the host through the controller.

[0018] Preferably, the mobile phone head and the host are connected by wire, the motor in the mobile phone head is connected to the host through a power line, and the host controls the rotation speed of the motor through the power line.

[0019] Preferably, it also includes a foot-controlled speed regulating device connected to the host, and the doctor can turn on the foot-controlled speed regulating device to fine-tune the engine speed after selecting the highest speed.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: before or during surgery, if the doctor needs to change the rotation speed of the handpiece head according to his or her actual operating habits and operating experience or when facing bones of different hardness, the doctor who operates the system of the present invention only needs to align the laser barcode corresponding to the required rotation speed with the barcode scanner by rotating the handpiece head. After the barcode scanner scans the barcode, the host automatically controls the motor to the required maximum rotation speed according to the received signal, and then uses the foot-controlled speed control device for fine-tuning to obtain the ideal working rotation speed. The operation is simple and reliable, the maximum rotation speed can be freely selected, and can be adapted to the tool head rotation speed that the doctor is accustomed to, thereby improving the safety of the operation. Furthermore, the doctor only needs to rotate the handpiece head to complete the speed adjustment during the speed adjustment process, without having to operate other equipment. The handpiece head can be disinfected, which is difficult to be disinfected as a whole in actual applications such as the barcode scanner, thereby ensuring the safety during the operation.

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0028] Example 1

[0029] like Figure 1 As shown, the present invention designs a mobile phone head for orthopedic surgery, including a housing, a motor 5 installed inside the mobile phone head, a driving head installed at the front end of the housing, and at least two barcodes 4 printed on the housing for scanning by a barcode scanner. The barcodes 4 are distributed on the housing, and each laser barcode represents a maximum speed, and each laser barcode controls a maximum speed of the motor. Other barcodes 4 of the maximum speed are stored in the barcode database and can be retrieved and used by the barcode scanner at any time.

[0030] During the specific implementation of this embodiment, the barcode 4 installed on the mobile phone head shell is a laser barcode, which is composed of scratches of different widths. The scratches can be filled with pigments, such as black pigments. The size of the shell is a cylinder with a diameter of 1.5-4 cm. There are five types of laser barcodes, and the five laser barcodes are distributed in a staggered stepped manner around the shell. This distribution method can avoid mis-scanning. The maximum rotation speeds represented by these five laser barcodes are 15000rpm, 20000rpm, 25000rpm, 30000rpm and 35000rpm respectively.

[0031] Before or during surgery, the user only needs to turn the head of the mobile phone to align the barcode representing the required maximum speed with the barcode scanner. The barcode scanner scans the barcode and transmits it to the host computer, which controls the motor to rotate to the required maximum speed.

[0032] Example 2

[0033] The present invention designs a mobile phone head for orthopedic surgery, including a shell, a motor 5 installed inside the mobile phone head and at least two barcodes 4 printed on the shell for being scanned by a barcode scanner. The barcodes 4 are distributed on the shell, each laser barcode represents a maximum rotation speed, and each laser barcode controls a maximum rotation speed of the motor.

[0034] In the specific implementation process of this embodiment, the barcode 4 installed on the mobile phone head shell is a laser barcode, which is composed of scratches of different widths. The scratches can be filled with pigments, such as black pigment. The shell is a pentagonal prism. There are five types of laser barcodes. The five types of laser barcodes are distributed on five prism surfaces respectively, and the distance between the barcodes on adjacent surfaces is greater than or equal to 4 cm.

[0035] Before or during surgery, the user only needs to turn the head of the mobile phone to align the barcode representing the required maximum speed with the barcode scanner. The barcode scanner scans the barcode and transmits it to the host computer, which controls the motor to rotate to the required maximum speed.

[0036] Example 3

[0037] like Figure 2 As shown, the present invention designs an intelligent speed change system for orthopedic surgery, including a host 1, a mobile phone head described in Example 1, a power line 2 and a barcode scanning gun 8 connected to the host 1, the host 1 is used to control the motor 5, the motor 5 is used to drive the driving head at the front end of the above-mentioned mobile phone head to rotate, and the host 1 is connected to the motor 5 through the power line 2.

[0038] In this embodiment, the system also includes a foot-controlled speed regulating device 7 connected to the host 1. When the maximum speed of the surgical tool is selected or the speed is changed, the switch 71 of the foot-controlled speed regulating device is pressed to turn on the foot-controlled speed regulating device 7. The foot-controlled speed regulating device 7 sends a signal to the host 1. The host 1 fine-tunes the speed of the handpiece head, and the tool head installed on the handpiece head can start working to obtain the ideal working speed.

[0039] In the specific implementation process of this embodiment, Figure 3The figure shows a plan view of a wireless barcode scanner, wherein the barcode scanner 8 is a wireless Bluetooth barcode scanner 8 with a high temperature resistant and sterilizable shell. When the doctor needs to determine the rotation speed of the mobile phone head before the operation, the doctor turns on the main power switch 11 of the host 1, and the host 1 automatically sends radio waves to the barcode scanner. The control panel 83 in the barcode scanner 8 receives the radio waves sent by the host 1 and then charges the battery 84 to start. The barcode scanner 8 flashes red and makes a sound to indicate that the barcode scanner has started. Then, the mobile phone head switch 31 is pressed to turn on the mobile phone head, and surgical tools, such as saws, drills, files, grinders and engravers, are installed on the driving head at the front end of the mobile phone head and the mobile phone head is rotated to the corresponding laser barcode 4 of the required rotation speed. The laser barcode is aligned with the barcode scanner 8. After pressing the barcode scanner switch 10, the rotation speed information obtained by the scanner 81 is transmitted to the control panel of the host 1 wirelessly through the transmitter 82. After receiving the signal, the host 1 presses the identification switch 9 to identify the signal and controls the motor 5 to rotate to the required rotation speed through the power line 2, and the mobile phone head can reach the selected maximum rotation speed. At the same time, the maximum rotation speed of the barcode and the image of the tool are displayed on the touch screen for the doctor to check and confirm. Or when the speed of the handpiece head needs to be changed during the operation, the laser barcode 4 corresponding to the required speed is aligned with the barcode scanner 8 or the mobile barcode scanner 8 is aligned with the barcode corresponding to the required speed. The barcode scanner 81 in the barcode scanner 8 scans the code. After the control board 83 confirms, the speed information is transmitted to the control board of the host 1 through the transmitter 82. At the same time, the touch screen displays the maximum speed of the barcode. After the doctor checks that it is correct, the handpiece head can reach the selected maximum speed. Each time a new speed is changed, the previous speed will be automatically eliminated, and only the current maximum speed will be retained. After the host 1 is turned off, all speeds disappear and return to 0.

[0040] Example 4

[0041] The present invention designs an intelligent speed change system for orthopedic surgery, including a host 1, a mobile phone head described in Example 1 and a barcode scanning gun 8 connected to the host 1, the host 1 is used to control a motor 5, the motor 5 is used to drive the driving head at the front end of the above-mentioned mobile phone head to rotate, a controller connected to the motor 5 is provided in the housing 3, and the mobile phone head is wirelessly connected to the host 1 through the controller.

[0042] In this embodiment, the system also includes a foot-controlled speed regulating device 7 connected to the host 1. When the maximum speed of the surgical tool is selected or the speed is changed, the switch 71 of the foot-controlled speed regulating device is pressed to turn on the foot-controlled speed regulating device 7. The foot-controlled speed regulating device 7 sends a signal to the host 1. The host 1 fine-tunes the speed of the handpiece head, and the tool head installed on the handpiece head can start working to obtain the ideal working speed.

[0043] In the specific implementation process of this embodiment, Figure 4The figure shows a plan view of a fixed barcode scanner. When the doctor needs to determine the rotation speed of the handpiece before surgery, the doctor turns on the main power switch 11 of the host 1, and the host 1 automatically sends radio waves to the barcode scanner. After receiving the radio waves sent by the host 1, the barcode scanner 8 starts the rechargeable battery 84. The barcode scanner 8 flashes red and makes a sound to indicate that the barcode scanner has been started. Then, the handpiece head switch 31 is pressed to turn on the handpiece head, and surgical tools, such as saws, drills, files, grinders and engravers, are installed on the driving head at the front end of the handpiece head and the handpiece head is rotated to the corresponding laser barcode 4 of the required rotation speed. The laser barcode is aligned with the barcode scanner 8. After pressing the barcode switch 10, the rotation speed information scanned by the scanner 81 is transmitted to the control panel of the host 1 through the transmitter 82 and the antenna 85. After receiving the signal, the host 1 presses the identification switch 9 to identify the signal and sends the signal to the controller in the handpiece head. After receiving the signal, the controller controls the motor 5 to rotate to the required rotation speed, and the handpiece head can reach the selected maximum rotation speed. At the same time, the touch screen displays the maximum rotation speed of the barcode and the image of the tool for the doctor to check and confirm. Or when the rotation speed of the handpiece head needs to be changed during the operation, the laser barcode 4 corresponding to the required rotation speed is aligned with the barcode scanner 8. After the barcode scanner 81 in the barcode scanner 8 scans and confirms, the rotation speed information is transmitted to the control panel of the host 1 through the transmitter 82 and the antenna 85. At the same time, the touch screen displays the maximum rotation speed of the barcode. After the doctor checks that it is correct, he starts the switch of the foot-controlled speed regulating device 7 to work, and the handpiece head can reach the selected maximum rotation speed. Every time a new rotation speed is changed, the previous rotation speed will be automatically eliminated, and only the maximum rotation speed of the time will be retained. After the host 1 is turned off, the rotation speed will disappear and return to 0. Each surgical tool can choose 5 different maximum rotation speeds, but different surgical tools have different optimal maximum rotation speeds. For example, the optimal maximum rotation speed of a reciprocating saw is 25000rpm. When using a reciprocating saw, the doctor only needs to turn the handpiece head to the barcode corresponding to 25000rpm to quickly get the required rotation speed. In addition, different doctors have different rotation speed requirements for different tool heads, and the rotation speeds required for bones of different hardness are also different.

[0044] like Figure 5 The figure shows a schematic diagram of a rotation speed database, in which other laser bar codes 4 with the highest rotation speeds are stored, which can be retrieved and used by a barcode scanner at any time.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the technical solution of the present invention, and are not intended to limit the specific implementation methods of the present invention.
