Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and in particular to a joint pressure measuring device and a joint pressure measuring system. Background Technology
[0002] In related technologies, with the increasing aging of the population, diseases such as osteoarthritis and rheumatoid arthritis can lead to cartilage damage or abnormal wear and tear in the knee joint, causing ligament imbalance and limited flexion and extension of the lower limbs. Joint surgery is required to restore lower limb function. Therefore, hospitals are performing an increasing number of joint surgeries each year.
[0003] In robot-assisted or surgical-assisted joint surgery, a joint pressure measuring device measures joint pressure by being directly inserted into the joint and bearing the joint's pressure. However, current joint pressure measuring devices generally require long-term storage. Furthermore, due to the limitations of their sealed structure, it is impossible to promptly ascertain the battery level and status of the device when it is powered off. Therefore, how to recharge the joint pressure measuring device without disassembling it has become a pressing problem. Utility Model Content
[0004] To address the aforementioned problems, according to a first aspect of the embodiments of this application, a joint pressure measuring device is provided, comprising: a first housing, a second housing, a pressure sensing device, a control circuit board, a charging circuit, and a battery;
[0005] The first housing and the second housing are opposite to each other, and the first housing and the second housing are connected in a manner that allows them to move relative to each other in the direction in which the second housing points toward the first housing; an installation space is provided between the first housing and the second housing, and the first housing and the second housing maintain the sealing of the installation space; the installation space is used to house the pressure sensing device, the control circuit board, the charging circuit and the battery;
[0006] The pressure sensing devices are arranged in an array on the plane of the first housing or the second housing; the control circuit board is electrically connected to the pressure sensing devices and the battery, and is at least used to acquire and transmit the sensing data of the pressure sensing devices.
[0007] The charging circuit is connected to the battery and is used to wirelessly charge the battery.
[0008] As can be seen from the above embodiments, wireless charging of the joint pressure measuring device through the charging circuit can achieve battery charging while avoiding disassembly of the joint pressure measuring device. This effectively simplifies the difficulty of charging and replenishing the battery of the joint pressure measuring device, and further prevents the battery of the joint pressure measuring device from losing power during long-term storage, thus avoiding affecting the measurement effect of the joint pressure measuring device.
[0009] According to a second aspect of the embodiments of this application, a joint pressure measurement system is provided, including any of the aforementioned joint pressure measurement devices;
[0010] The joint pressure measurement system also includes a display terminal; the display terminal is used to receive various data sent by the joint pressure measurement device and display the received data in a visual manner.
[0011] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description
[0012] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application.
[0013] Figure 1 This is a schematic diagram of the joint pressure measuring device according to an embodiment of this application.
[0014] Figure 2 This is a top view of a joint pressure measuring device according to an embodiment of this application. Detailed Implementation
[0015] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0016] In existing joint surgeries performed by surgical robots, or robot-assisted joint surgeries, it is necessary to measure joint pressure at the target location. Current joint pressure measurement devices require direct insertion into the joint to withstand the pressure. However, these devices typically require long-term storage, which can lead to battery depletion. Furthermore, due to the sealed structure of these devices, battery replacement requires specialized maintenance, making battery recharging relatively inconvenient. Therefore, finding a way to recharge the joint pressure measurement device without disassembling it has become a pressing issue.
[0017] To address the aforementioned problems, this application provides a joint pressure measuring device 10. Figure 1 The diagram shown is a structural schematic of the joint pressure measuring device 10. Figure 1 As shown, the joint pressure measuring device 10 includes: a first housing 11, a second housing 12, a pressure sensing device 13, a control circuit board 14, a charging circuit 15, and a battery 16.
[0018] The pressure sensing device 13 can be a resistive pressure sensor or a capacitive pressure sensor, but is not limited to these. The pressure sensing device 13 can also be other devices that can realize pressure sensing.
[0019] The first housing 11 and the second housing 12 are opposite each other and are connected in a manner that allows relative movement between the first housing 11 and the second housing 12 in the direction pointing from the second housing 12 toward the first housing 11. A mounting space M is provided between the first housing 11 and the second housing 12, and the first housing 11 and the second housing 12 maintain the sealing of the mounting space M. The mounting space M is used to house the pressure sensing device 13, the control circuit board 14, the charging circuit 15, and the battery 16.
[0020] Wherein, the direction in which the second outer shell 12 points to the first outer shell 11 is... Figure 1 The first direction X is shown in the figure. The first housing 11 and the second housing 12 are connected in a manner that allows them to move relative to each other in the direction from the second housing 12 to the first housing 11, that is, the first housing 11 and the second housing 12 are connected in a manner that allows them to move relative to each other in the first direction X.
[0021] Furthermore, the first outer shell 11 and the second outer shell 12 can be connected to each other by having a snap-fit tenon 111 on the first outer shell 11 and a snap-fit groove 121 on the second outer shell 12. The first outer shell 11 and the second outer shell 12 are engaged by snapping the snap-fit tenon 111 into the snap-fit groove 121. The length of the snap-fit tenon 111 and the depth of the snap-fit groove 121 allow the snap-fit tenon 111 to still move along the depth direction of the snap-fit groove 121 after engagement, thus enabling relative movement between the first outer shell 11 and the second outer shell 12. However, it should be noted that this connection between the first outer shell 11 and the second outer shell 12, achieved through the snap-fit tenon 111 and the snap-fit groove 121, allows relative movement between them in the first direction X.
[0022] Meanwhile, the first outer shell 11 and the second outer shell 12 can maintain the seal of the installation space M between the first outer shell 11 and the second outer shell 12. This can be achieved by setting a sealing strip between the first outer shell 11 and the second outer shell 12, or by filling the first outer shell 11 and the second outer shell 12 with other sealing materials to achieve the seal of the installation space M. There are no restrictions on this.
[0023] The pressure sensing devices 13 are arranged in an array on the plane of the first housing 11 or the second housing 12. The control circuit board 14 is electrically connected to the pressure sensing devices 13 and the battery 16, and is used at least to acquire and transmit the sensing data of the pressure sensing devices 13.
[0024] Among them, the plane where the first outer shell 11 is located, that is Figure 1 The plane containing surface B1 of the first outer casing 11 shown in the diagram. The plane containing the second outer casing 12, that is... Figure 1 The second housing 12 shown in the figure has surface B2 on the plane. The pressure sensing devices 13 are arranged in an array on the plane of surface B1, or in the plane of surface B2, or the planes of surface B1 and surface B2 are parallel. The pressure sensing devices 13 can be arranged in an array on two planes at the same time.
[0025] Furthermore, the control circuit board 14 transmits the sensing data from the pressure sensing device 13. This can be done via a wireless communication module on the control circuit board 14, or more specifically, via a Bluetooth wireless module, but is not limited to these methods. The control circuit board 14 can also transmit the sensing data from the pressure sensing device 13 via other wireless transmission protocols.
[0026] The charging circuit 15 is connected to the battery 16 and is used to wirelessly charge the battery 16.
[0027] By wirelessly charging the joint pressure measuring device 10 through the charging circuit 15, the battery 16 can be charged without disassembling the joint pressure measuring device 10. This effectively simplifies the charging and replenishment of the battery 16 of the joint pressure measuring device 10, and prevents the battery 16 of the joint pressure measuring device 10 from losing power during long-term storage, thus avoiding affecting the measurement effect of the joint pressure measuring device 10.
[0028] In some embodiments, such as Figure 1 As shown, the charging circuit 15 also includes a wireless charging control circuit 151 and a coupling coil 152.
[0029] The coupling coil 152 is used to receive wireless charging energy from the outside and convert it into electrical energy. The wireless charging control circuit 151 is connected to both the coupling coil 152 and the battery 16, and is used to control the electrical energy generated by the coupling coil 152 and input to the battery 16.
[0030] The coupling coil 152 is used to receive external wireless charging energy. It can convert external wireless charging energy into electrical energy through electromagnetic induction and input it into the battery 16. Since the efficiency of converting wireless charging energy into electrical energy through electromagnetic induction is higher than that of magnetic field resonance and radio wave wireless charging methods, the coupling coil 152 effectively improves the charging efficiency of the joint pressure measuring device 10, thereby enabling effective wireless charging of the joint pressure measuring device 10.
[0031] The first housing 11 includes a first bottom surface D1, and the second housing 12 includes a second bottom surface D2. The first bottom surface D1 and the second bottom surface D2 are opposite to each other in the direction from the second housing 12 to the first housing 11. The coupling coil 152 is attached to at least one of the first bottom surface D1 and the second bottom surface D2.
[0032] As mentioned earlier, the first bottom surface D1 and the second bottom surface D2 are opposite each other in the direction from the second outer shell 12 to the first outer shell 11, that is, the first bottom surface D1 and the second bottom surface D2 are opposite each other in the first direction X.
[0033] The coupling coil 152 is attached to at least one of the first bottom surface D1 and the second bottom surface D2. The coupling coil 152 can be attached to the first bottom surface D1, or it can be attached to the second bottom surface D2, or there can be two coupling coils 152 respectively attached to the first bottom surface D1 and the second bottom surface D2.
[0034] By attaching the coupling coil 152 to the first bottom surface D1 and / or the second bottom surface D2, the structure that wireless charging energy needs to pass through from outside the joint pressure measuring device 10 to reach the coupling coil 152 can be minimized. This reduces the energy attenuation caused by the wireless charging energy passing through other structures outside the coupling coil 152 inside the joint pressure measuring device 10, thereby further improving the energy conversion efficiency of the coupling coil 152, so that the coupling coil 152 can more effectively achieve the charging effect of the battery 16.
[0035] In some embodiments, such as Figure 1 As shown, the wireless charging control circuit 15 is integrated on the control circuit board 14.
[0036] This configuration effectively improves the integration level of the circuitry of the joint pressure measuring device 10, thereby reducing the space occupied by the wireless charging control circuit 15 within the installation space M. This allows for more space to be provided for other structures, such as a larger battery 16 to increase the working time of the joint pressure measuring device 10, or more pressure sensing devices 13 to improve the measurement accuracy of the joint pressure measuring device 10.
[0037] In some embodiments, the joint pressure measuring device 10 further includes a charging circuit board. A wireless charging control circuit 151 and a coupling coil 152 are disposed on the charging circuit board. The charging circuit board is attached to at least one of the first bottom surface D1 and the second bottom surface D2.
[0038] refer to Figure 1 The diagram shows that the wireless charging control circuit 151 and the coupling coil 152 are integrated on the charging circuit board, that is, Figure 1 The wireless charging circuit 151 and the coupling coil 152 shown are integrated on a single charging circuit board structure. This allows the wireless charging circuit 151 to be positioned close to the coupling coil 152, improving its efficiency in controlling the current generated by the coupling coil 152. Furthermore, by setting up this charging circuit board, the level of circuit integration of the joint pressure measuring device 10 can also be improved, providing more space for the installation of other structures within the joint pressure measuring device 10.
[0039] In some embodiments, reference Figure 1 As shown, the control circuit board 14 is equipped with a magnetic switch, which is used to open upon receiving an external magnetic signal. The magnetic switch also activates the control circuit board 14 after opening, and the control circuit board 14, after activation, controls the operation of the pressure sensing device 13.
[0040] By setting a magnetic switch on the control circuit board 14, the housing of the joint pressure measuring device 10 can be re-treated without affecting other switching methods. For example, it can prevent false triggering of the joint pressure measuring device 10 when sensing pressure when using a pressure switch, and it can also prevent the switching effect from being affected by low battery power or radio interference when using a wireless switch. The magnetic switch can directly control the control circuit board 14 through the magnetic force passing through the first housing 11 and the second housing 12, which can effectively ensure the sealing of the installation space M, and at the same time avoid the power consumption of active sensing switches. For example, it can prevent the power consumption of the battery 16 caused by the wireless switch still needing power to operate when it is off.
[0041] In some embodiments, Figure 2 The image shown is a top view of the joint pressure measuring device 10. Figure 1 The structural diagram shown is referenced. Figure 2 The top view shown indicates that the joint pressure measuring device 10 includes two force-bearing zones Q1. At least four pressure sensing devices 13 are arranged in an array within each force-bearing zone Q1. The pressure sensing devices 13 are fitted into either the first housing 11 or the second housing 12.
[0042] To enable the pressure sensing device 13 to conform to the first housing 11 or the second housing 12, refer to Figure 1 This diagram illustrates an embodiment where the pressure sensing device 13 is fitted onto the first housing 11. An array of sensor mounting brackets 131 is provided within the mounting space M. The sensing devices 131 extend from the bottom surface D2 of the second housing 12 toward the first housing 11, i.e., along the first direction X. The pressure sensing device 13 is fitted onto the first housing 11 by being mounted on the sensor mounting brackets 131. The sensor mounting brackets 131 can be configured to be integrally formed with the second housing 12, or they can be installed into the mounting space M after the second housing 12 is formed.
[0043] It should be noted that, although Figure 1 The illustrated embodiment shows the pressure sensing device 13 attached to the first housing 11; however, it is conceivable that an embodiment in which the pressure sensing device 13 is attached to the second housing 12 can also be referred to. Figure 1 As shown.
[0044] The pressure sensing devices 13 within the stress zone Q1 are symmetrically distributed within the joint pressure measuring device 10. Figure 2 The image shows the axis of symmetry Z of the joint pressure measuring device 10. The force-bearing area Q1 and the pressure sensing devices 13 within the force-bearing area Q1 are symmetrically distributed on both sides of the axis of symmetry Z.
[0045] Since the structure of the joint itself includes the protruding condyle structure, by symmetrically distributing the pressure sensing device 13 in the stress area Q1 and within the stress area Q1 within the joint pressure measuring device 10, the arrangement of the pressure sensing device 13 can be adapted to the shape of the joint, thereby improving the measurement accuracy of the joint pressure measuring device 10.
[0046] In some embodiments, such as Figure 1 and Figure 2 As shown, the joint pressure measuring device 10 also includes a connecting area Q2, which is located between the two force-bearing areas Q1.
[0047] The charging circuit 15 is located within the connection area Q2. At least one of the first housing 11 and the second housing 12 has a structure located at the connection area Q2 that is recessed into the joint pressure measuring device 10.
[0048] Specifically, at least one of the structures of the first outer shell 11 and the second outer shell 12 located at the connection area Q2 is recessed into the joint pressure measuring device 10. This can be either the structure of the first outer shell 11 located at the connection area Q2 being recessed into the joint pressure measuring device 10, or the structure of the second outer shell 12 located at the connection area Q2 being recessed into the joint pressure measuring device 10, or both the structures of the first outer shell 11 and the second outer shell 12 located at the connection area Q2 being recessed into the joint pressure measuring device 10.
[0049] and, Figure 1 An embodiment is shown where the second housing 12 is recessed into the joint pressure measuring device 10. (See reference...) Figure 1 As shown, the second outer casing 12 is recessed into the joint pressure measuring device 10, forming a recess 122. It should be noted that, although... Figure 1 The illustration shows an embodiment where the second housing 12 is recessed into the joint pressure measuring device 10 to form a recess 122, but an embodiment where the first housing 11 is recessed into the joint pressure measuring device 10 can also be referred to. Figure 1 As shown.
[0050] By recessing at least one of the first housing 11 and the second housing 12 into the joint pressure measuring device 10 at the connection area Q2, and placing the charging circuit 15 in the connection area Q2, the loss of wireless charging energy during its journey to the charging circuit 15 due to passing through the first housing 11 and the second housing 12 can be reduced by thinning the first housing 11 and / or the second housing 12. This further improves the utilization efficiency of the wireless charging energy by the charging circuit 15, effectively enhancing the wireless charging effect of the joint pressure measuring device 10.
[0051] In some embodiments, such as Figure 1 and Figure 2 As shown, the control circuit board 14 and the battery 16 are located in the connection area Q2 and the two force-bearing areas Q1.
[0052] In the aforementioned structure where at least one of the first outer shell 11 and the second outer shell 12 is recessed into the joint pressure measuring device 10 at the connection area Q2, the thickness of at least one of the first outer shell 11 and the second outer shell 12 at the connection area Q2 is reduced, thus decreasing the structural strength. However, by placing the control circuit board 14 and the battery 16 in the connection area Q2 and the two stress areas Q1, the structural strength of the first outer shell 11 and the second outer shell 12 in the connection area Q2 can be reinforced by the structure of the control circuit board 14 and the battery 16. In particular, the battery 16, which itself possesses considerable structural strength, can effectively reinforce the structural strength of the first outer shell 11 and the second outer shell 12.
[0053] Therefore, by controlling the circuit board 14 and the battery 16 to be disposed in the connection area Q2 and the two stress areas Q1, the structure of the first shell 11 and the second shell 12 can be reinforced by controlling the structure of the circuit board 14 and the battery 16. Thus, while thinning the first shell 11 and / or the second shell 12 to achieve better wireless charging effect, the overall structural strength of the joint pressure measuring device 10 can be maintained. In this way, the structural strength of the joint pressure measuring device 10 can be avoided while improving the wireless charging efficiency.
[0054] In some embodiments, such as Figure 1 and Figure 2 As shown, the control circuit board 14 is equipped with multiple charging indicator lights 17.
[0055] When the joint pressure measuring device 10 is wirelessly charged, multiple charging indicator lights 17 are used to emit light through the first housing 11 and / or the second housing 12, and to indicate the power status of the joint pressure measuring device 10 by the illuminated charging indicator lights 17.
[0056] The power status of the joint pressure measuring device 10 is indicated by the number of illuminated charging indicator lights 17, or by the color of the light emitted by the charging indicator lights 17. However, it is not limited to this, and the charging indicator lights 17 can also indicate the power status of the joint pressure measuring device 10 in other possible ways.
[0057] By setting the charging indicator light 17 to indicate the power status of the joint pressure measuring device 10, the power status of the joint pressure measuring device 10 can be understood most intuitively.
[0058] This application also provides a joint pressure measurement system. The joint pressure measurement system includes any of the aforementioned joint pressure measuring devices 10. Specifically, the joint pressure measurement system may include a display terminal for displaying the status and measurement data of the joint pressure measuring device 10, a processor for receiving data sent by the joint pressure measuring device 10, and a wireless charging module for wirelessly charging the joint pressure measuring device 10, but is not limited thereto.
[0059] The processor receives radio communication information from the joint pressure measuring device 10 and acquires its contents. Specifically, the information sent by the joint pressure measuring device 10 may include its measurement information and battery level information. After acquiring the contents of the radio communication information, the processor displays these contents visually via a display terminal. When the processor confirms that the battery level is low, it can also alert the joint pressure measuring device 10 to the low battery level through visual display and by playing a prompt tone.
[0060] When the joint pressure measuring device 10 is placed on the wireless charging module, wireless charging can be achieved. The joint pressure measuring device 10 may also have markings on its surface to remind users that the charging efficiency is optimal when the joint pressure measuring device 10 is placed on the wireless charging module with a specific side facing out.
