Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and in particular to a rapid measuring device and an oral surgery robot. Background Technology
[0002] In related technologies, with the continuous development of society, people are paying more and more attention to oral health. As a result, hospitals are performing more and more oral surgeries every year.
[0003] In robotic-assisted or robotic-manual oral surgery, the drill bits used to power the robot may come from different suppliers, and these drill bits may have different specifications. Therefore, when changing drill bits, it may be necessary to re-enter the drill bit data into the surgical robot system. Current solutions typically involve the surgeon measuring the data using a fixed measuring instrument. This method can lead to reading errors and is time-consuming. Therefore, rapidly measuring and reading drill bit data remains a pressing issue that needs to be addressed. Utility Model Content
[0004] To address the aforementioned problems, according to a first aspect of the embodiments of this application, a rapid measuring device is provided for rapidly measuring the length of an oral drill bit, comprising: a guide rod, a guide cylinder, a first structural plate, and a second structural plate;
[0005] The guide rod passes through the guide cylinder and engages with the guide cylinder in a manner that allows it to move relative to the guide cylinder; one end of the guide rod includes a rod measuring end, and one end of the guide cylinder includes a cylinder measuring end; the rod measuring end of the guide rod extends out of the guide cylinder from the cylinder measuring end.
[0006] The first structural plate is disposed at the rod measuring end, and the second structural plate is disposed at the cylinder measuring end; the first structural plate is provided with a slot for quickly mounting the installation end of the drill bit; the second structural plate is provided with a guide groove corresponding to the slot, the guide groove being used to cooperate with the drilling end of the drill bit to quickly determine the orientation of the drill bit; the first structural plate is also provided with a distance measuring part, the distance measuring part being used to obtain the length of the drill bit by measuring the distance between the first structural plate and the second structural plate after the drill bit is mounted.
[0007] As described in the above embodiments, during use, a relatively long distance is first established between the first and second structural plates by moving the guide cylinder. Then, the mounting end of the drill bit is clamped into the slot. After clamping, the guide cylinder is moved so that the second structural plate abuts against the drilling end of the drill bit, thereby determining the orientation of the drill bit and fixing its position. The distance between the first and second structural plates is measured by the distance measuring unit to obtain the length of the drill bit. Thus, the above device enables rapid clamping and accurate reading of the drill bit. Simultaneously, the slot and guide groove design stabilize and limit the position of the drill bit during rapid clamping, achieving a reading with minimal error. Therefore, the aforementioned design simultaneously achieves both minimal error in drill bit measurement and rapid reading.
[0008] According to a second aspect of the embodiments of this application, an oral surgery robot is provided, including any of the aforementioned rapid measuring devices; the oral surgery robot further includes a wireless transmission module for acquiring the measurement readings of the rapid measuring device via wireless transmission.
[0009] 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

[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] To address the aforementioned problems, this application provides a rapid measuring device 10. Figure 1 The diagram shown is a structural schematic of the rapid measuring device 10. Figure 2 and Figure 3 The diagrams shown are schematic representations of the 10 structural components of the rapid measuring device. For example... Figure 1 As shown, and refer to Figure 2 and Figure 3 The structure shown, the rapid measuring device 10, includes: a guide rod 11, a guide cylinder 12, a first structural plate 13, and a second structural plate 14.
[0017] The guide rod 11 passes through the guide cylinder 12 and engages with the guide cylinder 12 in a manner that allows it to move relative to the guide cylinder 12. One end of the guide rod 11 includes a rod measuring end C1, and one end of the guide cylinder 12 includes a cylinder measuring end D1. The rod measuring end C1 of the guide rod 11 extends out of the guide cylinder 12 from the cylinder measuring end D1.
[0018] The guide rod 11 passes through the guide cylinder 12, meaning that the guide rod 11 is located inside the guide cylinder 12. Figure 1 The diagram shows the first direction Y, where the guide rod 11 is engaged with the guide cylinder 12 in a manner that allows it to move relative to the guide cylinder 12, that is, the guide rod 11 is engaged with the guide cylinder 12 in a manner that allows it to move relative to the guide cylinder 12 in the first direction Y.
[0019] A first structural plate 13 is disposed at the rod measuring end C1, and a second structural plate 14 is disposed at the cylinder measuring end D1. The first structural plate 13 has a slot 131 for quickly mounting the mounting end 21 of the drill bit 20. The second structural plate 14 has a guide groove 141 corresponding to the slot 131, which engages with the drilling end 22 of the drill bit 20 to quickly determine the orientation of the drill bit 20. The first structural plate 13 also has a distance measuring part 15, which is used to obtain the length of the drill bit 20 by measuring the distance between the first structural plate 13 and the second structural plate 14 after the drill bit 20 is mounted.
[0020] The mounting end 21 of the drill bit 20 is used to install it onto the end of the robotic arm of the oral surgery robot, while the drilling end 22 of the drill bit 20 is specifically used to perform drilling operations during oral surgery. Furthermore, the second structural plate 14 has a guide groove 141 corresponding to the slot 131, meaning the axis of the slot 131 and the axis of the guide groove 141 are on the same straight line. This ensures that the drill bit 20, after being mounted, is perpendicular to both the first structural plate 13 and the second structural plate 14, and consequently ensures that the distance between the first structural plate 13 and the second structural plate 14 measured by the ranging unit 15 is the length of the drill bit 20.
[0021] Meanwhile, the guide groove 141 is used to cooperate with the drilling end 22 of the drill bit 20 to quickly determine the orientation of the drill bit 20. That is, after the mounting end 21 of the drill bit 20 is engaged in the slot 131, the drill bit 20 still has some degrees of freedom that are not restricted. Through the contact between the drill bit 20 and the guide groove 141, the drill bit 20 can be secured between the first structural plate 13 and the second structural plate 14, thereby restricting the degrees of freedom of the drill bit 20 and preventing it from moving and causing deviations in the measured dimensions when measuring the dimensions of the drill bit 20.
[0022] In use, the guide cylinder 12 is first moved to create a relatively long distance between the first structural plate 13 and the second structural plate 14. Then, the mounting end 21 of the drill bit 20 is clamped into the slot 131. After clamping, the guide cylinder 12 is moved so that the second structural plate 14 abuts against the drilling end 22 of the drill bit 20, thus determining the orientation of the drill bit 20 and fixing its position. The distance between the first structural plate 13 and the second structural plate 14 is measured by the distance measuring unit 15 to obtain the length of the drill bit 20. Therefore, the above-described device enables rapid clamping and accurate reading of the drill bit 20. Simultaneously, the slot 131 and guide groove 141 stabilize and limit the position of the drill bit 20 during rapid clamping, resulting in a smaller reading error. Thus, the aforementioned configuration simultaneously achieves both a smaller measurement error and rapid reading of the drill bit 20.
[0023] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the first structural plate 13 includes a first mounting portion 132 and a first measuring portion 133. The second structural plate 14 includes a second mounting portion 142 and a second measuring portion 143.
[0024] The first mounting part 132 is provided with a mounting slot 131, the first measuring part 133 is provided with a distance measuring part 15, and the second mounting part 142 is provided with a guide groove 141. The first mounting part 132 and the second mounting part 142 are arranged opposite to each other, and the first measuring part 133 and the second measuring part 143 are arranged opposite to each other.
[0025] The first mounting portion 132 and the second mounting portion 142 are arranged opposite to each other, meaning their surfaces are parallel to each other. More specifically, the surface of the first mounting portion 132 facing the second mounting portion 142 is parallel to the surface of the second mounting portion 142 facing the first mounting portion 132. Similarly, the first measuring portion 133 and the second measuring portion 143 are arranged opposite to each other, meaning their surfaces are parallel to each other. More specifically, the surface of the first measuring portion 133 facing the second measuring portion 143 is parallel to the surface of the second measuring portion 143 facing the first measuring portion 133.
[0026] The first mounting part 132 and the first measuring part 133 are located on opposite sides of the guide rod 11 along its length axis. The second mounting part 142 and the second measuring part 143 are located on opposite sides of the guide cylinder 12 along its length axis.
[0027] In this case, the axes of guide rod 11 and guide cylinder 12 are located on the same straight line, therefore, Figure 3 The axis Z1 shown is simultaneously the axis of the guide rod 11 and the guide cylinder 12. The first mounting portion 132 and the second mounting portion 142 are located on opposite sides of the guide rod 11 along its length axis, that is, the first mounting portion 132 and the first measuring portion 133 are located on opposite sides of axis Z1 and are connected to the guide rod 11. Similarly, the second mounting portion 142 and the second measuring portion 143 are located on opposite sides of the guide cylinder 12 along its length axis, that is, the second mounting portion 142 and the second measuring portion 143 are located on opposite sides of axis Z1 and are connected to the guide cylinder 12.
[0028] When using the rapid measuring device 10, if the guide cylinder 12 needs to move on the guide rod 11, the movement of the guide cylinder 12 and the components connected to the guide cylinder 12 in the direction of the guide rod 11 can be achieved directly by moving the second measuring part 143.
[0029] By symmetrically arranging the first mounting part 132 and the first measuring part 133 on both sides of the guide rod 11, and symmetrically arranging the second mounting part 142 and the second measuring part 143 on both sides of the guide cylinder 12, mutual interference can be avoided when the mounting part and the measuring part are located on the same side of the axis Z1.
[0030] Furthermore, the drill bit 20 includes a drill bit for oral surgery, which has a relatively thin structure and is relatively susceptible to pressure. Since the first measuring section 133 also needs to be equipped with a ranging section 15, by placing the ranging section 15 and the first mounting section 132 on opposite sides of the guide rod 11, the weight of the ranging section 15 can be mainly borne by the guide rod 11. This avoids the ranging section 15 applying excessive pressure to the drill bit 20 mounted on the first mounting section 132 when the ranging section 15 and the first mounting section 132 are on the same side, thus preventing the drill bit 20 structure from being affected and deformed.
[0031] Therefore, through the aforementioned arrangement, the mutual interference between the mounting part and the ranging part can be avoided, thereby improving the measurement accuracy of the ranging part 15, and the deformation of the drill bit 20 caused by the pressure applied by the ranging part 15 can be avoided, thus affecting the use of the drill bit 20.
[0032] In some embodiments, such as Figure 1 As shown, and refer to Figure 2 and Figure 3The schematic diagram shows that the surface of the ranging section 15 facing the second measuring section 143 is flush with the surface of the first mounting section 132 facing the second mounting section 142.
[0033] The surface of the second mounting part 142 facing the first mounting part 132 is flush with the surface of the second measuring part 143 facing the measuring part 15.
[0034] With the aforementioned setup, the length data of the drill bit 20 can be obtained directly by acquiring the reading of the measuring unit 15 without needing to perform any further compensation processing on the reading acquired by the measuring unit 15. This further improves the speed at which the rapid measuring device 10 acquires the length data of the drill bit 20.
[0035] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the guide rod 11 passes through the first mounting portion 132. The first mounting portion 132 and the first measuring portion 133 are located on different planes. A support connecting portion 134 extending along the extending direction of the guide rod 11 is also provided between the first mounting portion 132 and the first measuring portion 133. The support connecting portion 134 connects the first mounting portion 132 and the first measuring portion 133. The support connecting portion 134 is in contact with the guide rod 11.
[0036] Although the first mounting part 132 and the first measuring part 133 are located on different planes, they remain parallel to each other to ensure the accuracy of the readings obtained by the ranging part 15. The support connecting part 134 extends along the extension direction of the guide rod 11, that is, the support connecting part 134 extends along the first direction Y.
[0037] By having the guide rod 11 pass through the first mounting portion 132 and the support connection portion 134 extending along the first direction Y contact the guide rod 11, the weight of the ranging portion 15 can be more distributed to the structure of the guide rod 11 through the support connection portion 134. Figure 3 The pressure portion of the ranging section 15 toward the second measuring section 143 shown is converted into pressure of the support connection section 134 toward the guide rod 11, thereby further reducing the pressure of the ranging section 15 on the drill bit 20, and further preventing the pressure of the ranging section 15 from affecting the structure of the drill bit 20.
[0038] In some embodiments, Figure 4 The diagram shown is a structural schematic of the fastener 16. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the rapid measuring device 10 also includes a fastening part 16.
[0039] The fastening part 16 includes a fastening cylinder 161 and a fastening nut 162. The outer wall of the fastening cylinder 161 is provided with threads, and the fastening nut 162 is installed on the outer wall of the fastening cylinder 161 by means of threads.
[0040] A guide connecting portion 144 is provided between the second mounting portion 142 and the guide cylinder 12, and between the second measuring portion 143 and the guide cylinder 12. The width of the guide connecting portion 144 is smaller than the width of the second mounting portion 142 and the second measuring portion 143.
[0041] The end of the guide rod 11 furthest from the measuring end C1 is fixed to the bottom 163 of the fastening cylinder 161. Starting from the side of the cylinder wall furthest from its bottom 163, the fastening cylinder 161 has symmetrically arranged grooves 164. A guide connecting part 144 is correspondingly disposed within the groove 164, and the width of the guide connecting part 144 is the same as the width of the groove 164.
[0042] The guide cylinder 12 is fitted onto the guide rod 11, and the fastening cylinder 161 is fitted onto the guide cylinder 12, thereby allowing the guide cylinder 12 to move along the guide rod 11. The guide cylinder 12 is fixedly clamped by the outer wall of the fastening cylinder 161 through the rotation of the fastening nut 162 on the fastening cylinder 161.
[0043] Furthermore, the fastening cylinder 161 has symmetrically formed grooves 164 on the cylinder wall starting from the side away from its bottom 163. The width of the guide connecting part 144 is the same as the width of the groove 164, allowing the second clamping part 142 and the second measuring part 143 to connect with the guide cylinder 12 through the guide connecting part 144 passing through the groove 164. At the same time, the cooperating guide connecting part 144 and the groove 164 can play a limiting role, ensuring that the relative positions of the first clamping part 132 and the second clamping part 142, as well as the relative positions of the first measuring part 133 and the second measuring part 143, are naturally maintained during the movement of the guide cylinder 12.
[0044] When using the rapid measuring device 10, since no other structures are installed on the second measuring part 143, and it is connected to the guide cylinder 12 through the guide connection part 144, the guide cylinder 12 and other structures connected to the guide cylinder 12, such as the second clamping part 142, can still be moved together by moving the second measuring part 143.
[0045] Through the aforementioned configuration, the relative positions of the first mounting portion 132 and the second mounting portion 142, as well as the relative positions of the first measuring portion 133 and the second measuring portion 143, can be naturally maintained during the movement of the guide cylinder 12. Furthermore, the structure of the fastening cylinder 161 and the fastening nut 162 also secures the guide cylinder 12 and all structures connected to it. Simultaneously, by moving the second measuring portion 143 to move the guide cylinder 12 and its connected structures, measurement errors caused by contact with measurement-related structures, such as the drill bit 20 mounted in the slot 131, can be avoided when moving other structures.
[0046] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, when the drilling end 22 of the drill bit 20 is flat, the guide groove 141 is a flat-bottomed groove. When the drilling end 22 of the drill bit 20 is pointed, the guide groove 141 is a conical groove recessed towards its center. When the drilling end 22 of the drill bit 20 is round, the guide groove 141 is an arc-shaped groove recessed towards its center.
[0047] With this configuration, when the drill end 22 is flat, its contact with the guide groove 141 is achieved because the guide groove 141 has a flat bottom. Therefore, the contact surfaces of the drill end 22 and the guide groove 141 are planar, naturally tending to maintain a close fit. When the drill end 22 is pointed, the guide groove 141, being a conical groove recessed towards its center, naturally tends to move towards the center of the guide groove 141. The pointed end and the conical groove bottom cooperate to hold the drill end 22 in that position, preventing it from moving elsewhere. Similarly, when the drill end 22 is round, the guide groove 141, being an arc-shaped groove recessed towards its center, naturally tends to move towards the center of the guide groove 141. The round end and the arc-shaped groove bottom cooperate to hold the drill end 22 in that position, preventing it from moving elsewhere.
[0048] With the aforementioned configuration, the guide groove 141 naturally allows the drill bit 20 to move to and maintain a fixed position during the fixing process, thereby further improving the measurement accuracy of the ranging unit 15. Furthermore, by avoiding adjustments to the drill bit 20's position during the fixing process, the measurement speed of the ranging unit 15 can be further improved. Therefore, the aforementioned configuration can simultaneously enhance both the measurement accuracy and measurement speed of the ranging unit 15.
[0049] In some embodiments, such as Figure 2 and Figure 3 As shown, and refer to Figure 1As shown, the first mounting portion 132 has at least two mounting slots 131. The second mounting portion 142 has at least two guide grooves 141 corresponding to the at least two mounting slots 131. The at least two guide grooves 141 include at least two of the following: flat-bottomed grooves, conical grooves, and arc-shaped grooves.
[0050] The first mounting portion 132 may have two, three, four, or five slots 131, but is not limited thereto. The second mounting portion 142 may have the same number of guide slots 141. Preferably, the first mounting portion 132 may have three slots 131, and the second mounting portion 142 may have three guide slots 141, wherein the three guide slots 141 are respectively a flat-bottomed groove, a conical groove, and an arc-shaped groove. Thus, it can be ensured that any drill end 22 has a matching guide slot 141 to maximize the accuracy and efficiency of its mounting measurement reading. Through embodiments other than the preferred embodiment, it can still be ensured that two or three drill ends 22 can be matched, or that multiple drill bits 20 can be measured simultaneously, thereby improving the measurement speed of the rapid measuring device 10.
[0051] In some embodiments, such as Figure 2 and Figure 3 As shown, and refer to Figure 1 As shown, the cross-sectional diameter of the guide groove 141 is larger than the cross-sectional diameter of the drill bit 20.
[0052] This design allows for the adaptation of drill bits 20 with more different cross-sectional diameters. Furthermore, in conjunction with the aforementioned guide groove 141 configuration, even if the cross-sectional diameter of the drill bit 20 is smaller than that of the guide groove 141, the drill bit 20 can still be moved to a fixed position and held under the guidance of the aforementioned guide groove 141 configuration.
[0053] In some embodiments, the ranging unit 15 includes a laser ranging unit. This configuration allows the ranging unit 15 to specifically measure the distance between the first measuring unit 133 and the second measuring unit 143.
[0054] In some embodiments, the ranging unit 15 also integrates a wireless output module for outputting measurement readings to an external structure via wireless transmission.
[0055] This application also provides an oral surgery robot. It includes a rapid measuring device 10 as described above. The oral surgery robot further includes a wireless transmission module for acquiring measurement readings from the rapid measuring device 10 via wireless transmission.
[0056] With this setup, the oral surgery robot can directly obtain the measurement readings from the rapid measuring device 10, without having to manually input the measurement readings into the oral surgery robot after the rapid measuring device 10 completes the measurement. This further improves the efficiency of the oral surgery robot in performing or assisting in performing surgery.
[0057] The above embodiments of this application can complement each other without causing conflict.
[0058] It should be noted that the dimensions of layers and regions may be exaggerated in the accompanying drawings for clarity. Furthermore, it is understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element, or there may be intermediate layers.
