[0015] In the description of this application, it should be noted that, unless otherwise explicitly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0016] The technical solution of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this application, not all embodiments.

[0017] like Figures 1 to 18 As shown, one embodiment of this application provides a spinal probe, which includes: The housing includes a main body 100 and a handle 200, and a ratchet 230 is built into the housing. An impedance sensor assembly 300 is inserted into the main body 100. One end of the impedance sensor assembly 300 is connected to the ratchet 230, and the impedance sensor assembly 300 is arranged perpendicular to the rotation plane of the ratchet 230. The impedance sensor assembly 300 has an impedance detection electrode 320 built in it, and the other end of the impedance sensor assembly 300 is used to detect reactance data through the impedance detection electrode 320. The ratchet 230 and the handle 200 are locked in the positive upward direction of the rotation direction of the ratchet 230. A slider 600 is disposed on the impedance sensor assembly 300 and / or the main body 100 and is arranged away from the handle 200. The slider 600 can slide along the length direction of the impedance sensor assembly 300. The position detection unit 700 is used to detect the real-time position of the sliding member 600.

[0018] In this embodiment, the ratchet 230 and the handle 200 are locked in the forward direction of rotation. This allows the handle 200 to rotate synchronously with the ratchet 230 and the connected impedance sensor assembly 300, enabling tapping and drilling operations. When rotating in the reverse direction, they are not locked and rotate asynchronously, allowing the handle 200 to quickly reset for the next forward drilling operation, effectively accelerating the drilling pace. Simultaneously, the slider 600, in conjunction with the position detection unit 700, can detect the sliding position of the slider 600 in real time, directly obtaining the drilling depth and overcoming the deficiency of existing technologies lacking a direct depth measurement method. The overall structure of this embodiment is rationally designed and easy to operate, significantly improving efficiency and operational safety.

[0019] The aforementioned housing may include an upper housing, a lower housing, and a top cover, such as Figures 1 to 3 The upper and lower shells are joined together to form the entire main body 100 and part of the handle 200. The top cover seals the top of the overall structure formed by the upper and lower shells, forming another part of the handle 200.

[0020] The main body 100 is a hollow tubular structure.

[0021] The handle portion 200 has a pre-reserved mounting cavity inside, which can be used to house a ratchet 230. The ratchet 230 can rotate flexibly inside the cavity without shifting.

[0022] The ratchet 230 and the handle 200 are engaged by a locking structure. Specifically, the two are locked in the forward direction of the ratchet 230's rotation. When the user rotates the handle 200 forward, the handle 200 can drive the ratchet 230 to rotate synchronously through the locking structure, which in turn drives the impedance sensor assembly 300 to rotate synchronously. When the handle 200 is rotated in the reverse direction, the two are unlocked and do not move together. The ratchet 230 will not drive the impedance sensor assembly 300 to rotate in the reverse direction, thereby achieving a quick reset of the handle 200 and facilitating subsequent continuous tapping and drilling.

[0023] The impedance sensor assembly 300 is the core functional component of the spinal probe. It is shaped like a slender rod and is inserted into the hollow interior of the main body 100. One end of the rod extends into the handle 200 and is connected to the axis of the ratchet 230. The axis of the assembly is arranged perpendicular to the rotation plane of the ratchet 230, so that the ratchet 230 can stably drive the impedance sensor assembly 300 to rotate synchronously when it rotates, thereby realizing the tapping and drilling operation.

[0024] The impedance sensor assembly 300 described above can have a hollow internal design with an impedance detection electrode 320 built in. When in use, it can directly contact the tissues around the spine and collect tissue reactance data in real time through the built-in impedance detection electrode 320, providing accurate feedback for users to determine the tissue type (such as bone, soft tissue, neurovascular).

[0025] The aforementioned slider 600 can adopt a ring structure or other slidable structure. It can be disposed on the impedance sensor assembly 300 or the main body 100, or cooperate with both the impedance sensor assembly 300 and the main body 100, and be arranged away from the handle 200.

[0026] The length of the aforementioned sliding member 600 can be set according to the drilling depth detection requirements. Positioning marks can be set on its outer wall to achieve precise positioning in conjunction with the position detection unit 700. During use, as the impedance sensor assembly 300 advances through the borehole, the sliding member 600 is pushed in the opposite direction by the detection part, sliding along the length of the impedance sensor assembly 300 towards the handle 200. Its sliding displacement has a linear relationship with the drilling depth, providing a basis for depth detection.

[0027] The aforementioned position detection unit 700 employs a linear position sensor, or alternatively, a ranging sensor. It is fixedly installed inside the main body 100 or on its outer wall, corresponding to the sliding member 600, to detect the sliding position of the sliding member 600 in real time. The position detection unit 700 and the sliding member 600 can be in a non-contact or contact manner. In the contact manner, the sliding member 600 may have a contact point that engages with the detection end of the position detection unit 700 and moves synchronously with the sliding member 600.

[0028] The aforementioned position detection unit 700 can convert the sliding displacement signal of the slider 600 into an electrical signal, transmit it to an external control device, and then calculate the precise drilling depth, providing real-time feedback to the user.

[0029] In some implementations, the ratchet 230 and the handle 200 can switch between locked and unlocked states in opposite directions of the ratchet 230's rotation.

[0030] The locking engagement between the ratchet 230 and the handle 200 can be further configured such that the two are always locked in the forward direction of the ratchet 230's rotation; in the reverse direction of the ratchet 230's rotation, they can switch between locked and unlocked states. When switched to the unlocked state, the handle 200 rotates in the opposite direction and does not interact with the ratchet 230, allowing for quick reset. When switched to the locked state, the handle 200 rotates in the opposite direction, which can drive the ratchet 230 to rotate synchronously, enabling the probe to be rotated out in the opposite direction or its position to be finely adjusted.

[0031] In this embodiment, by setting the ratchet 230 and the handle 200 to two working states—locked and unlocked—in reverse order, the flexibility of the instrument is greatly improved while retaining the forward drilling transmission function. In the unlocked state, the handle 200 can quickly idle and reset, making continuous tapping more efficient; in the locked state, reverse rotation can synchronously drive the probe to rotate, facilitating probe withdrawal from the bone hole or correction of the drilling position, meeting different operational needs. This design is simple, reliable, and easy to operate, without increasing the overall size and complexity of the instrument, while balancing efficient drilling and safe needle withdrawal, further improving the adaptability and safety of spinal drilling operations.

[0032] In some implementations, reference Figure 2 , 4 6 to 10, a first support member 210 is provided inside the handle part 200. The first support member 210 is fixedly disposed relative to the handle part 200. The ratchet 230 is rotatably disposed inside the first support member 210. The impedance sensor assembly 300 passes through the first support member 210 and is connected to the ratchet 230. The spinal probe also includes a locking mechanism, which is used to lock the ratchet 230 and the first support member 210 in the positive upward direction of the ratchet 230 rotation direction.

[0033] The handle portion 200 is provided with a first support member 210. The first support member 210 can be in the form of an annular sleeve structure. It can be fixed relative to the handle portion 200 by any of the following methods: interference fit, snap-fit, bolt fixation, etc. It can be provided with an annular receiving hole inside, and the ratchet 230 is embedded in the hole and can rotate flexibly.

[0034] The axis of the first support member 210 can be coaxially aligned with the axis of the ratchet 230. After the impedance sensor assembly 300 passes through the through hole, it is connected to the ratchet 230 and is perpendicular to the rotation plane of the ratchet 230.

[0035] The locking mechanism described above may include two sub-components that restrict the forward and reverse rotation of the ratchet 230. When either component contacts the ratchet 230, it can restrict the rotation in the corresponding direction.

[0036] In some implementations, reference Figures 7 to 10 The first support member 210 has a receiving hole for accommodating the rotation of the ratchet 230, and the ratchet 230 has ratchet teeth on its periphery. The locking mechanism includes: The first locking member 221 is provided with a first limiting tooth, which abuts against the ratchet tooth of the ratchet 230, and is used to lock the ratchet 230 and the first support member 210 in the positive direction of the rotation of the ratchet 230, while allowing rotation in the opposite direction.

[0037] The first support member 210 may have a receiving hole adapted to the ratchet 230. The receiving hole is an annular through hole with an inner diameter slightly larger than the outer diameter of the ratchet 230, so that the ratchet 230 can rotate flexibly in the hole without deviation, providing precise rotation limit for the ratchet 230.

[0038] The ratchet 230 is provided with evenly distributed ratchet teeth on its periphery, which are adapted to the limiting requirements of the locking mechanism.

[0039] The first locking member 221 can be fixedly connected to the inner wall of the first support member 210. A first limiting tooth is formed on the side near the ratchet 230. The tooth shape of the first limiting tooth can limit the ratchet 230 from rotating in the forward direction. That is, when the ratchet 230 rotates in the forward direction, the first limiting tooth engages with the ratchet tooth and abuts, thereby locking the ratchet 230 and the first support member 210 in the forward direction. When the ratchet 230 rotates in the reverse direction, the first limiting tooth cannot effectively abut with the ratchet tooth, so it cannot be locked. The ratchet 230 can rotate freely in the reverse direction without affecting the reset of the handle part 200.

[0040] In this embodiment, the first locking member 221 precisely abuts against the ratchet teeth of the ratchet 230 via the first limiting tooth, stably locking the two in the forward direction. This ensures that the power for the forward rotation of the handle 200 is stably transmitted to the impedance sensor assembly 300, enabling tapping and drilling. Simultaneously, this structure does not restrict the reverse rotation of the ratchet 230, allowing for rapid reset of the handle 200 and improving continuous drilling efficiency. In this embodiment, the first locking member 221 has a simple structure, is easy to install, has strong compatibility with the receiving hole and ratchet 230, does not increase the size of the instrument, has low wear, and high stability.

[0041] In some implementations, reference Figures 7 to 10 The locking mechanism also includes: The second locking member 222 is provided with a second limiting tooth. When the second limiting tooth abuts against the ratchet tooth of the ratchet 230, it is used to lock the ratchet 230 and the first support member 210 in the opposite direction of the rotation direction of the ratchet 230, while it can rotate in the forward direction. The switching element 224 is disposed on the handle part 200 and is used to adjust the contact state between the second locking element 222 and the ratchet teeth of the ratchet 230.

[0042] Based on the first locking component 221, the above-mentioned locking mechanism adds a second locking component 222 and a switching component 224, which work together with the first support component 210 and the ratchet 230 to achieve flexible control of forward and reverse locking.

[0043] The second locking member 222 has a second limiting tooth at one end facing the ratchet 230. The tooth shape is adapted to the ratchet teeth on the periphery of the ratchet 230 and is symmetrically arranged with the first limiting tooth of the first locking member 221 to achieve the restriction of reverse rotation.

[0044] The aforementioned switching element 224 can be a knob or a paddle, and can penetrate through the side wall of the handle portion 200 and extend into the interior of the handle portion 200, allowing for manual rotation or paddle operation. When the switching element 224 is rotated to the first position, the second locking element 222 is pushed to abut against the ratchet teeth of the ratchet 230, at which point the ratchet 230 and the first support member 210 are locked when rotated in the opposite direction; when switched to the second position, the switching element 224 causes the second locking element 222 to disengage from the ratchet teeth of the ratchet 230, and the reverse locking is released.

[0045] In this embodiment, the overall structure formed by the second locking member 222 and the switching member 224 is highly compatible with the first locking member 221 and the first support member 210, is compact and does not occupy extra space, and does not affect the overall grip feel of the device.

[0046] In some implementations, reference Figure 7 , 8 The ratchet 230 is restrained on the tap rod 310 by the snap ring 232 to prevent the ratchet 230 from displacing along the length of the tap rod 310.

[0047] In some implementations, reference Figure 9 , 10 An expansion cavity communicating with the receiving hole is provided at the edge of the receiving hole. The first locking member 221 and the second locking member 222 are both arranged in the expansion cavity. The first locking member 221 and the second locking member 222 are connected by a locking elastic member 223. The locking elastic member 223 is used to provide elastic force so that the first locking member 221 and the second locking member 222 abut against the ratchet teeth of the ratchet wheel 230. A protrusion is arranged on the switching member 224. The switching member 224 is used to drive the protrusion to rotate synchronously, so that the second locking member 222 moves away from the ratchet teeth of the ratchet wheel 230.

[0048] An expansion cavity can be formed at the edge of the receiving hole of the first support member 210. The expansion cavity is connected to the receiving hole and its size is adapted to the first locking member 221 and the second locking member 222. It is used to accommodate and install the first locking member 221, the second locking member 222 and the locking elastic member 223.

[0049] The first locking member 221 and the second locking member 222 can be symmetrically arranged in the expanded cavity. Their adjacent ends are fixedly connected by a locking elastic member 223 (optional medical stainless steel spring). The locking elastic member 223 provides elastic force in its natural state, pushing the first locking member 221 and the second locking member 222 to move toward the ratchet 230, so that the first limiting teeth and the second limiting teeth of the two members are tightly abutted against the ratchet teeth on the periphery of the ratchet 230.

[0050] The aforementioned switching component 224 is a knob type, penetrating the side wall of the handle portion 200 and extending above the expansion cavity. One end of it facing the second locking component 222 may have a protrusion. When the switching component 224 is rotated in the first direction, the protrusion rotates synchronously and squeezes the second locking component 222, overcoming the elastic force of the locking elastic component 223, and pushing the second locking component 222 to move away from the ratchet 230, so that the second limiting tooth disengages from the ratchet and releases the reverse locking. When the switching component 224 is rotated in the second direction, the locking elastic component 223 resets, driving the second locking component 222 back to its original position, re-engaging with the ratchet, and re-realizing the reverse locking.

[0051] In this embodiment, the expanded cavity provides dedicated installation space for the first locking member 221, the second locking member 222, and the locking elastic member 223, resulting in a high degree of integration and a compact structure for the locking mechanism. This does not occupy additional internal space in the handle portion 200, nor does it affect the rotation of the ratchet 230 or the operation of other components. The locking elastic member 223 continuously provides elasticity, ensuring stable contact between the first and second locking members 222 and the ratchet teeth of the ratchet 230, maintaining reliable forward and reverse locking and preventing operational hazards caused by loosening of the lock. Simultaneously, the switching member 224 achieves rapid switching of the second locking member 222 through the compression of the protrusion, making operation convenient and effortless. Theoretically, users can operate the locking and unlocking mechanism with one hand, improving operational efficiency.

[0052] In some implementations, reference Figures 2 to 5 Impedance sensor assembly 300, including: The tap bar 310 is hollow inside and one end is connected to the ratchet 230. Impedance detection electrode 320 is inserted through tap rod 310.

[0053] The aforementioned tap rod 310 is generally slender and rod-shaped, with a hollow through hole opened along the axial direction inside. The inner diameter of the through hole is adapted to the outer diameter of the impedance detection electrode 320, providing a transmission channel for the impedance detection electrode 320.

[0054] The tap rod 310 is connected to the handle 200 at one end near the handle 200. The connection method can be a snap-fit ​​or a threaded connection, so that the tap rod 310 can be rotated synchronously when the handle 200 rotates, thus realizing tapping and drilling operations. The other end of the tap rod 310 (the end away from the handle 200) is provided with tapping teeth to meet the drilling needs of spinal bone.

[0055] The impedance detection electrode 320 is inserted into the hollow through hole of the tap rod 310, with its detection end extending out of the end of the tap rod 310 away from the handle 200, and is used to contact the tissues around the spine to collect reactance data.

[0056] In this embodiment, the tap rod 310 and the ratchet 230 work together to achieve integrated tapping and impedance detection, eliminating the need for frequent instrument changes, improving surgical efficiency, and featuring a compact structure and strong stability, meeting the precision and convenience requirements of clinical surgery.

[0057] In some implementations, reference Figures 6 to 10 The ratchet 230 has a quick-connect hole on its shaft, and at least one snap-fit ​​groove 231 is provided on the edge of the quick-connect hole; the tap 310 has a snap-fit ​​part 311 that matches the snap-fit ​​groove 231, and the tap 310 is detachably connected to the ratchet 230 through the snap-fit ​​part 311 and the snap-fit ​​groove 231.

[0058] The ratchet 230 has a quick-connect hole along its own axis at its shaft center. The inner diameter of the quick-connect hole is matched with the outer diameter of the tap 310 near the ratchet 230, so that the tap 310 can be smoothly inserted into the hole.

[0059] At least one locking groove 231 is provided on the edge of the quick-connect hole, and two grooves can be symmetrically arranged, extending along the inner wall of the hole. The section of the tap shank 310 near the ratchet 230 has a matching locking part 311 corresponding to the locking groove 231, and the locking part 311 is adapted to the locking groove 231. During assembly, the end of the tap shank 310 is inserted into the quick-connect hole, and the locking part 311 is aligned with the locking groove 231, thus achieving relative locking and fixation of the two in the rotation direction of the ratchet 230.

[0060] In this embodiment, the combination structure of quick-connect through hole, snap-fit ​​groove 231 and snap-fit ​​part 311 makes installation and disassembly convenient, facilitates component replacement, and ensures stable and reliable connection. Power can be stably transmitted to tap rod 310, and slippage or deviation is not easy to occur, thus improving the accuracy of tapping and drilling.

[0061] In some implementations, reference Figures 1 to 5 The slider 600 is sleeved on the impedance sensor assembly 300 and arranged away from the handle part 200. The slider 600 can slide along the length direction of the impedance sensor assembly 300.

[0062] The aforementioned slider 600 can adopt a ring structure adapted to the tap rod 310 (the outer part of the impedance sensor assembly 300).

[0063] The aforementioned sliding member 600 is sleeved on the tap rod 310 of the impedance sensor assembly 300 and is arranged far away from the handle part 200, effectively avoiding the operating area of ​​the handle part 200 and preventing interference with the handle part 200 during operation, which would affect the surgical operation.

[0064] The aforementioned sliding member 600 can slide smoothly along the length of the tap rod 310 without jamming or offsetting. Furthermore, the sliding process does not affect the tapping rotation of the tap rod 310, nor does it damage the electrical connection between the tap rod 310 and the external electrode 324.

[0065] The length of the aforementioned sliding member 600 can be set according to the drilling depth detection requirements. Its outer wall can be provided with anti-slip texture or positioning marks to facilitate precise cooperation with the position detection unit 700 and achieve stable acquisition of displacement signals.

[0066] In this embodiment, the annular sleeve structure allows the slider 600 to slide precisely along the length of the tap rod 310 without offset or jamming, providing a stable displacement basis for the position detection unit 700. Furthermore, the slider 600 is positioned away from the handle 200 to prevent interference with the operation of the handle 200, and does not affect the user's ability to hold the handle 200 for tapping and drilling operations.

[0067] In some implementations, reference Figures 1 to 5 The end of the slider 600 near the handle portion 200 passes through the main body portion 100.

[0068] In this embodiment, the end of the slider 600 near the handle portion 200 passes through the main body portion 100. The through hole of the main body portion 100 and the impedance sensor assembly 300 can play a coordinated guiding role for the slider 600, effectively preventing the slider 600 from radially shifting or tilting when sliding along the tap rod 310, so that the displacement of the slider 600 corresponds precisely to the drilling depth.

[0069] In some implementations, reference Figures 1 to 5 The aforementioned spinal probe also includes a sleeve elastic element 800 connected between the slider 600 and the main body 100, for providing the slider 600 with an elastic force away from the handle 200 along the length direction of the impedance sensor assembly 300.

[0070] The aforementioned sleeve elastic element 800 is connected between the sliding element 600 and the main body 100. Since the top end of the sliding element 600 is always lower than the bottom end of the main body 100, it can be directly disposed between the bottom end of the main body 100 and the top end of the sliding element 600. It should be noted that the sleeve elastic element 800 is intended to provide the sliding element 600 with an elastic force along the length of the impedance sensor assembly 300 away from the handle portion 200. As long as this elastic force is provided, the specific arrangement is not specifically required in this embodiment.

[0071] In this embodiment, the sleeve elastic element 800 is connected between the sliding element 600 and the main body 100. When drilling ends or the probe is retracted, the sleeve elastic element 800 resets, which can drive the sliding element 600 to quickly return to its initial position without the need for manual adjustment by the user. At the same time, the elastic force continuously pushes the sliding element 600 to move away from the handle 200, which can keep the sliding element 600 in contact with the surface of the detection area, so that the displacement of the sliding element 600 corresponds precisely to the drilling depth, further improving the depth measurement accuracy of the position detection unit 700 and effectively preventing depth measurement errors caused by loose contact.

[0072] In some implementations, reference Figures 1 to 5 The aforementioned spinal probe also includes: The sleeve elastic element 800 has one end connected to the inside of the main body 100 near the handle part 200, and the other end connected to the sliding element 600 near the handle part 200.

[0073] The aforementioned slider 600 is inserted into the main body 100 at one end near the handle portion 200.

[0074] One end of the aforementioned sleeve elastic element 800 is connected to the end of the slider 600 that penetrates the main body 100, and the other end is fixedly connected to the end of the main body 100 near the handle 200. In its natural state, the sleeve elastic element 800 is in an extended state, providing the slider 600 with an elastic force along the length of the impedance sensor assembly 300, away from the handle 200. When drilling is advanced, the slider 600 is compressed by the vertebral tissue, sliding towards the handle 200, compressing the sleeve elastic element 800. When drilling stops or the probe retracts, the sleeve elastic element 800 elastically resets, causing the slider 600 to return to its initial position away from the handle 200.

[0075] In this embodiment, the end of the slider 600 near the handle portion 200 passes through the main body portion 100, and the sleeve elastic member 800 is connected between the main body portion 100 and the slider 600, which can effectively prevent external factors from interfering with the sleeve elastic member 800.

[0076] It should be noted that in some embodiments, one end of the sleeve elastic member 800 can be fixedly connected to the end of the main body 100 away from the handle 200, and the other end can be connected to the end of the slider 600 that penetrates the main body 100. In this case, when the drill is pushed forward, the slider 600 is squeezed by the vertebral tissue and slides towards the handle 200, stretching the sleeve elastic member 800. When the drill stops or the probe is withdrawn, the sleeve elastic member 800 elastically resets, causing the slider 600 to return to its initial position away from the handle 200.

[0077] In some implementations, reference Figures 4 to 5 The slider 600 has a contact point at one end near the handle portion 200. The position detection unit 700 includes a linear detection unit disposed inside the main body portion 100 and arranged along the length direction of the main body portion 100. The contact point can slide along the linear detection unit. The linear detection unit is used to detect the real-time position of the contact point on the linear detection unit.

[0078] The aforementioned slider 600 has a raised contact point at one end near the handle portion 200, which moves synchronously with the slider 600. A linear detection unit is fixed inside the main body 100 and laid along the length of the main body 100, with its detection end corresponding to and abutting the contact point of the slider 600. When the slider 600 slides along the impedance sensor assembly 300, the contact point moves synchronously with the slider 600. The linear detection unit captures the sliding trajectory of the contact point in real time, accurately obtaining the displacement distance of the slider 600 by detecting the position change of the contact point, and then calculating the corresponding drilling depth. This process does not affect the power transmission of the tap rod 310's rotation, nor does it disrupt the electrical connection between the tap rod 310 and the external electrode 324.

[0079] In this embodiment, the cooperation between the contact and the linear detection unit enables real-time and accurate detection of drilling depth. Simultaneously, the linear detection unit is arranged along the length of the main body 100, perfectly matching the sliding trajectory of the slider 600, allowing for rapid capture of displacement signals and a quick response, eliminating the need for complex adjustments and reducing operational difficulty.

[0080] In some implementations, the linear detection unit is a potential sensor.

[0081] In this embodiment, the potential sensor has a rapid response and high detection accuracy, and can accurately capture the real-time sliding displacement of the slider 600, quickly converting the displacement signal into a recognizable electrical signal.

[0082] In some implementations, reference Figure 2 , 11 Up to 13, the spinal probe also includes a circuit board assembly, a first elastic conductive connector 510, and a second elastic conductive connector 520 disposed in the handle portion 200, and the circuit board assembly has electrode through holes; Impedance sensor assembly 300 includes: The tap bar 310 is hollow inside and one end is connected to the ratchet 230. The impedance detection electrode 320 includes a conductive base 321, an inner electrode 322, an outer electrode 324, and an insulating layer 323 disposed between the inner electrode 322 and the outer electrode 324. The inner electrode 322, the outer electrode 324, and the insulating layer 323 are all inserted through a tap rod 310. The conductive base 321 has a protruding post on its end face near the tap rod 310, which passes through an electrode through hole. One end of the inner electrode 322 near the handle portion 200 passes through the conductive base 321 and is electrically connected to the conductive base 321. The tap rod 310 is electrically connected to the outer electrode 324. The conductive base 321 is insulated from the tap rod 310 and the outer electrode 324. One end of the first elastic conductive connector 510 is connected to the tap rod 310, and the other end is elastically and electrically connected to the circuit board assembly. The second elastic conductive connector 520 elastically abuts against the protruding post and the electrode through hole.

[0083] The aforementioned circuit board assembly can be installed inside the handle portion 200, avoiding the first support member 210, ratchet 230, and locking mechanism, without interfering with the movement of the components. Its surface has through-hole electrodes for mounting and conductive connection to the conductive base 321. The relevant circuitry for the impedance detection electrode 320 in the circuit board assembly can be found in [reference needed]. Figure 15 (The J3 terminal in the diagram connects to the inner and outer electrodes). The relevant circuitry for the position detection unit 700 can be found in the following reference. Figure 16 (The J2 terminal in the diagram is connected to a potential sensor.) The relevant circuitry for the controller can be found in the reference diagram. Figure 17 The relevant circuitry for the Human-Computer Interaction Unit 900 can be found in [reference]. Figure 18 .

[0084] The impedance sensor assembly 300 described above includes a tap rod 310 and an impedance detection electrode 320.

[0085] The impedance detection electrode 320 includes a conductive base 321, an inner electrode 322, an outer electrode 324, and an insulating layer 323. The inner electrode 322 and the outer electrode 324 are both made of medical conductive material, and the insulating layer 323 is made of medical insulating material. It is disposed between the inner electrode 322 and the outer electrode 324 to achieve insulation and isolation between the two. The three are integrated and inserted into the hollow channel of the tap rod 310.

[0086] The aforementioned conductive base 321 is disposed within the handle portion 200, between the circuit board assembly and the tap rod 310. A protruding post is integrally formed on the end face near the tap rod 310, which is adapted to and passes through the electrode through-hole of the circuit board assembly. The end of the inner electrode 322 near the handle portion 200 passes through the conductive base 321, achieving fixation and electrical connection with the conductive base 321. Insulation structures are provided between the conductive base 321 and the outer electrode 324, ensuring mutual insulation. The conductive base 321 does not contact the tap rod 310, thus achieving insulation through air.

[0087] One end of the first elastic conductive connector 510 is fixedly connected to the end of the tap rod 310 near the handle portion 200, and the other end elastically abuts against the corresponding conductive contact of the circuit board assembly, realizing the electrical connection between the tap rod 310 and the external electrode 324 and the elastic electrical connection between the circuit board assembly; the second elastic conductive connector 520 is sleeved on the outside of the protruding post of the conductive base 321 and elastically abuts against the inner wall between the protruding post and the electrode through hole, realizing the electrical connection between the conductive base 321 and the inner electrode 322 and the elastic electrical connection between the circuit board assembly, so that the impedance signal is transmitted stably and does not affect the rotation of the tap rod 310 and the normal operation of the sliding member 600.

[0088] In this embodiment, the inner electrode 322 is connected to the circuit board assembly via the conductive base 321 and the second elastic conductive connector 520, while the outer electrode 324 is connected to the circuit board assembly via the tap rod 310 and the first elastic conductive connector 510. This dual elastic conductive cooperation ensures tight contact and stable conductivity, effectively preventing impedance signal distortion caused by poor contact. Simultaneously, an insulating layer 323 is provided between the inner electrode 322 and the outer electrode 324, and the conductive base 321 is insulated from the tap rod 310 and the outer electrode 324. This effectively prevents short circuits and conductive interference between the inner and outer electrodes 324, improving the accuracy of impedance detection. Furthermore, each conductive connection structure is independent, not affecting the power transmission between the tap rod 310 and the ratchet 230, the sliding of the sliding member 600, or the extension and retraction of the sleeve elastic member 800.

[0089] In some implementations, reference Figure 13 The upper end face of the tap rod 310 is lower than the lower end face of the conductive base 321.

[0090] In this embodiment, the upper end face of the tap rod 310 is lower than the lower end face of the conductive base 321, which can form a reliable insulating clearance space between the tap rod 310 and the conductive base 321, preventing direct contact between the two from causing a short circuit between the inner and outer electrodes 324.

[0091] In some implementations, reference Figure 2 , 11 Up to 13, the circuit board assembly includes: The first circuit board 410 is disposed within the handle portion 200; The second circuit board 420 is disposed in the handle portion 200 and electrically connected to the first circuit board 410. The second circuit board 420 has an electrode through hole. The second elastic conductive connector 520 elastically abuts between the protruding post and the electrode through hole. One end of the first elastic conductive connector 510 is connected to the tap rod 310, and the other end is elastically and electrically connected to the second circuit board 420.

[0092] The aforementioned first circuit board 410 can be understood as the main circuit board, used to realize data processing and connect to the human-computer interaction unit 900, etc.

[0093] The aforementioned second circuit board 420 can be understood as a secondary circuit board, used to connect with the hardware structure to realize signal acquisition and conversion.

[0094] The aforementioned first circuit board 410 can be disposed in the empty area inside the handle portion 200.

[0095] The aforementioned second circuit board 420 is located near the conductive base 321, and electrode through holes are provided on the board for the protruding pillars to pass through.

[0096] The first circuit board 410 and the second circuit board 420 can be electrically connected through conductive pins or flexible ribbon cables to complete the division of labor and cooperation between signal acquisition and data processing.

[0097] In this embodiment, the separate design of the main and auxiliary circuit boards allows for functional partitioning. The main circuit board handles data processing and human-machine interaction, while the auxiliary circuit board is dedicated to signal acquisition and hardware switching, effectively reducing circuit layout complexity and signal interference. Simultaneously, this structure fully utilizes the internal space of the handle 200, avoiding moving parts such as the ratchet 230 and locking mechanism, simplifying assembly. Furthermore, separating the acquisition and processing circuits improves the stability and detection accuracy of impedance signal transmission, while also facilitating individual maintenance and replacement, reducing repair costs, and enhancing the overall reliability and lifespan of the instrument.

[0098] In some implementations, reference Figure 13 , 14 The aforementioned spinal probe also includes an insulating element 530, which is disposed between the external electrode 324 and the conductive base 321.

[0099] The aforementioned insulating component 530 can be integrally sleeve-shaped. The insulating component 530 is fixedly disposed between the outer electrode 324 and the conductive base 321, specifically sleeved on the outer side of the end of the outer electrode 324 near the conductive base 321. Its size is adapted to the outer electrode 324 and the conductive base 321, does not affect the electrical connection between the inner electrode 322 and the conductive base 321, and does not interfere with the electrical connection between the tap rod 310 and the outer electrode 324. At the same time, it avoids the first and second elastic conductive connectors 520, and does not affect signal transmission or the rotation and quick-release replacement of the tap rod 310.

[0100] In some implementations, reference Figure 12 , 13 An insulating layer 323 covers the outer surface of the inner electrode 322, and an outer electrode 324 covers the outer surface of the insulating layer 323. The protruding post is provided with a blind hole. The inner electrode 322 passes through the blind hole and extends into the conductive base 321 and is electrically connected to the conductive base 321. The insulating element 530 is an insulating sleeve that is fitted on the outer electrode 324 to form insulation between it and the conductive base 321.

[0101] The outer surface of the inner electrode 322 is tightly covered with an insulating layer 323, and the outer surface of the insulating layer 323 is further covered with an outer electrode 324, forming a coaxial nested integrated electrode structure.

[0102] The center of the protruding post of the conductive base 321 is provided with a blind hole, and the end of the inner electrode 322 extends into the interior of the conductive base 321 through the blind hole and is stably electrically connected to the conductive base 321.

[0103] The aforementioned insulating component 530 is an insulating sleeve, which is directly sleeved on the outer side of the end of the outer electrode 324 near the conductive base 321, completely separating the outer electrode 324 from the conductive base 321, achieving reliable insulation between the two, without interfering with the conductive connection between the inner electrode 322 and the conductive base 321, and without affecting the rotation of the tap rod 310, quick-release replacement, and signal transmission of the elastic conductive connector.

[0104] In some implementations, reference Figure 13 The second elastic conductive connector 520 is a crown spring.

[0105] The aforementioned crown spring is sleeved on the protruding post of the conductive base 321 and elastically abuts against the inner wall of the electrode through hole of the second circuit board 420. It uses its own radial elastic force to achieve a stable electrical connection between the protruding post and the electrode through hole. The crown spring has a compact overall structure and can be directly snapped into a preset position during assembly without interfering with the outer electrode 324 or the insulating sleeve. At the same time, it does not affect the electrical conduction between the inner electrode 322 and the conductive base 321, nor does it hinder the rotation and quick-release replacement of the tap rod 310.

[0106] In this embodiment, the second elastic conductive connector 520 adopts a crown spring structure, which can achieve uniform circumferential contact between the conductive base 321 and the second circuit board 420. The conductive contact area is large and the stability is strong, which can effectively prevent poor contact caused by vibration and rotation, and make the impedance signal transmission continuous and stable. At the same time, the crown spring is small in size and highly adaptable, which can make full use of the narrow space in the electrode through hole, and the assembly is simple and efficient.

[0107] In some implementations, reference Figure 13 A limiting part 521 is provided on the crown spring. The movement of the crown spring can be restricted by the limiting part 521.

[0108] In some implementations, reference Figures 11 to 13 The insulating layer 323 covers the outer surface of the inner electrode 322, and the outer electrode 324 covers the outer surface of the insulating layer 323; the first elastic conductive connector 510 has a clamping part and an elastic abutting part, the clamping part is snapped onto the tap rod 310, and the elastic abutting part abuts against the circuit board assembly.

[0109] The aforementioned first elastic conductive connector 510 can be integrally formed with a clamping part and an elastic abutment part. The clamping part is an annular buckle or slot structure adapted to the tap rod 310, which can be firmly clamped to the outer side of the end of the tap rod 310 near the handle part 200 to achieve stable fixation and electrical connection with the tap rod 310. The elastic abutment part can be an elastic protrusion or an elastic spring sheet structure, which elastically abuts against the corresponding conductive contact of the circuit board assembly, specifically the second circuit board 420, in its natural state, to achieve an elastic electrical connection between the first elastic conductive connector 510 and the circuit board assembly, ensuring stable signal transmission.

[0110] In this embodiment, the clamping part and the elastic abutment part of the first elastic conductive connector 510 have a clear division of labor. The clamping part can be firmly clamped to the tap rod 310 to achieve stable fixation and electrical connection between the two, preventing loosening of contact due to rotation or vibration of the tap rod 310 during use. The elastic abutment part can always be tightly abutted against the circuit board assembly, so that the signal transmission between the external electrode 324 and the circuit board assembly is continuous and stable.

[0111] In some embodiments, the clamping part is fixed to the main body 100 by bolts.

[0112] In this embodiment, the clamping part is fixed to the main body 100 by bolts, which can reliably position the first elastic conductive connector 510 and effectively prevent it from loosening or shifting when the tap rod 310 rotates or the instrument vibrates, so that the clamping part and the external electrode 324, and the elastic contact part and the circuit board assembly always maintain stable conductive contact.

[0113] like Figure 19As shown, this application embodiment also provides a spinal probe ranging method, which is applied to the controller of the above-mentioned spinal probe. The spinal probe also includes a human-machine interaction unit 900 electrically connected to the controller. The impedance detection electrode 320, the position detection unit 700 and the human-machine interaction unit 900 are all electrically connected to the controller. The spinal probe ranging method includes steps S100 to S500. Step S100: Acquire the reactance data collected by the impedance detection electrode 320; Step S200: Determine the reactance status based on the reactance data and display it through the human-machine interaction unit 900; Step S300: Obtain displacement data collected by the position detection unit 700; Step S400: Determine the drilling depth based on the displacement data and display it through the human-computer interaction unit 900; In step S500, the ranging result is determined based on the reactance status and drilling depth, and then displayed through the human-machine interaction unit 900.

[0114] The method in this embodiment is based on the aforementioned spinal probe, and therefore possesses all the beneficial effects brought by the aforementioned spinal probe.

[0115] In step S100 above, after the controller starts, the impedance detection electrode 320 is activated synchronously, controlling the inner electrode 322 and the outer electrode 324 to enter the working state. The inner electrode 322 establishes an electrical connection with the controller through the conductive base 321 and the second elastic conductive connector 520 crown spring, while the outer electrode 324 establishes an electrical connection with the controller through the tap rod 310 and the first elastic conductive connector 510. When the tap rod 310 drives the detection end of the impedance detection electrode 320 to contact the spinal tissue, a circuit is formed between the inner electrode 322 and the outer electrode 324, collecting circuit characteristic data (including impedance value, capacitive reactance value, etc.) corresponding to different tissues of the spine (such as bone, soft tissue, nerves). The collected reactance data is transferred by the second circuit board 420 and preliminarily filtered and noise-reduced by the first circuit board 410 (main circuit board) before being transmitted to the controller. The controller can further analyze the circuit characteristic data using the voltage divider method to obtain reactance data and store it in the built-in storage module.

[0116] Specifically, reactance data can be obtained using a voltage divider method. The circuit consists of a preset standard fixed resistor connected in series with the spinal tissue being measured (equivalent to the measured impedance). The inner electrode 322 and the outer electrode 324 are respectively connected to the two ends of the voltage divider circuit. When the tap rod 310 drives the detection end of the impedance detection electrode 320 to contact the spinal tissue, the circuit is opened. Utilizing the voltage divider principle, the voltage division value between the fixed resistor and the measured tissue is detected. The detected voltage divider signal is filtered and noise-reduced before being transmitted to the controller. The controller obtains the reactance data through a voltage divider algorithm.

[0117] In step S200 above, the controller has a built-in preset reactance threshold database. This database stores the standard reactance ranges corresponding to different tissues of the spine (normal bone, osteoporotic bone, soft tissue, and nerve tissue). The controller compares the real-time reactance data obtained in step S100 with the preset reactance thresholds to determine the reactance status of the currently contacting tissue. Specifically, if the real-time reactance data is within the threshold range corresponding to normal bone, the reactance status is determined to be "normal bone contact"; if it is within the threshold range of osteoporotic bone, it is determined to be "osteoporotic bone contact"; if it is within the threshold range of soft tissue or nerve tissue, it is determined to be "non-bone contact". After the determination is completed, the controller sends a control signal to the human-machine interface unit 900, which provides a visual or voice display. For example, the display screen shows the corresponding reactance status text and real-time reactance value, the indicator lights up accordingly (e.g., green for normal bone, red for non-bone), the voice module broadcasts the reactance status simultaneously, and the buzzer sounds an alarm at different frequencies, allowing users to monitor the tissue contact status in real time.

[0118] In step S300 above, during the tapping and drilling operation of the tap rod 310, the sliding member 600 is compressed by the vertebral tissue and slides along the length direction of the impedance sensor assembly 300 of the tap rod 310 towards the handle portion 200. The contact point of the sliding member 600 at the end near the handle portion 200 moves synchronously with the sliding member 600, and the contact point is always in contact with the linear detection unit (e.g., a potential sensor). The linear detection unit captures the sliding displacement of the contact point in real time, converts the displacement signal into a recognizable electrical signal, and transmits it to the controller after being converted by the second circuit board 420. The controller acquires the displacement electrical signal in real time, converts the electrical signal into the actual displacement data of the sliding member 600 through a built-in algorithm, and calibrates the displacement data with the initial drilling position as the zero point to eliminate the initial error, so that the displacement data is consistent with the actual sliding distance of the sliding member 600, and stores the displacement data synchronously for subsequent drilling depth calculation.

[0119] In step S400 above, the controller can use the displacement data obtained in step S300, where the displacement of the sliding member 600 is equal to the drilling depth of the tapping teeth of the tap rod 310. The controller sends the drilling depth data to the human-machine interface unit 900, which displays the current drilling depth value in real time on the screen. A depth warning threshold can also be set. When the drilling depth approaches the preset safety threshold, the human-machine interface unit 900 alerts medical personnel through flashing indicator lights or voice prompts to avoid excessive drilling that could cause tissue damage.

[0120] In step S500 above, the controller can combine the reactance status determined in step S200 and the drilling depth determined in step S400 to comprehensively determine the ranging result. The core determination logic can be: combining the reactance status to confirm the tissue type at the current drilling location, and combining the drilling depth to confirm the actual depth of the current drilling, with the two working together to form a complete ranging result. Specifically, if the reactance status is "normal bone contact", the ranging result is "current drilling depth XXmm, contacting normal bone, work can continue"; if the reactance status is "porous bone contact", the ranging result is "current drilling depth XXmm, contacting porous bone, it is recommended to slow down the operation"; if the reactance status is "non-bone contact", the ranging result is "current drilling depth XXmm, contacting non-bone tissue (soft tissue / nerve), please stop the operation immediately". After the determination is completed, the controller sends the complete ranging result to the human-machine interaction unit 900, which is clearly displayed on the screen and broadcast simultaneously by the voice module. At the same time, the ranging result and the corresponding reactance data and displacement data are stored in the controller for subsequent traceability, which further improves the safety and accuracy of the operation.
