Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a bone needle fixation type tracer. Background Technology

[0002] As a crucial component of orthopedic surgical navigation and positioning systems, the tracker is used to indicate the patient's spatial position during orthopedic surgery. A secure connection and stable relative position between the tracker and the patient are essential for ensuring surgical precision. Current bone pin-fixed trackers require at least two bone pins to penetrate the skin and muscles into the bone tissue, with the tracker mounted on the pins for fixation.

[0003] However, bone needles are prone to deviation after insertion, making it difficult to install the tracer. When there is a large deviation in the bone needle, it is necessary to repeatedly remove and insert the bone needle, which prolongs the operation time and aggravates the patient's trauma. Summary of the Invention

[0004] The purpose of this application is to at least address the problem of difficulty in installing the tracer when there is deviation in the bone needle. This purpose is achieved through the following means:

[0005] This application discloses a bone pin fixation tracer, comprising a clamping mechanism and a tracking mechanism. The clamping mechanism includes a clamping member, a clamping structure, and a clamping plate. The clamping member includes a main body, a first clamping arm, and a second clamping arm. Both the first clamping arm and the clamping plate are used to abut against a first bone pin. The clamping plate is correspondingly disposed with respect to the first clamping arm and is rotatably disposed on the main body to create an angle relative to the first clamping arm. The first clamping arm is elastically connected to the main body to move closer to or further away from the clamping plate. The clamping structure and the second clamping arm are both used to abut against a second bone pin. The clamping structure is disposed on the main body and correspondingly disposed with respect to the second clamping arm. The second clamping arm is elastically connected to the main body to move closer to or further away from the clamping plate. The tracking mechanism is disposed on the main body and is used to provide position information.

[0006] The bone pin fixing tracer of this embodiment features a rotatable clamping plate. This allows the clamping plate to flexibly adjust the angle between itself and the first clamping arm, precisely fitting the first bone pin and ensuring stable clamping of the bone pin by the first clamping arm and clamping plate, avoiding instability caused by angle mismatch. This adapts to positional deviations of the first bone pin, reducing the installation difficulty of the bone pin fixing tracer. Because the clamping plate is rotatable, it can contact the first bone pin at a suitable angle, optimizing the contact area between the clamping plate and the first bone pin. This allows the clamping force generated between the clamping plate and the first clamping arm to be evenly distributed on the surface of the first bone pin, reducing force dispersion and improving the stability of the first bone pin fixation. Furthermore, the rotatable clamping plate allows the clamping mechanism to adapt to various types of bone pins, increasing the versatility of the bone pin fixing tracer of this embodiment.

[0007] In some embodiments, the first clamping arm includes a clamping arm body elastically connected to the main body and an abutting portion disposed on the clamping arm body. The abutting portion has a first end face and a second end face, the first end face and the second end face intersect to form an abutting edge, the abutting edge being used to abut against the first bone needle and disposed opposite to the clamping plate.

[0008] In some embodiments, the clamping structure is a clamping groove for clamping the second bone needle, and the clamping groove is disposed opposite to the second clamping arm.

[0009] In some embodiments, in the width direction of the main body, the first clamping arm and the second clamping arm are located on both sides of the main body, one end of the main body in the length direction is elastically connected to the first clamping arm and defines a first groove, and the other end of the main body in the length direction is elastically connected to the second clamping arm and defines a second groove.

[0010] In some embodiments, the clamping mechanism further includes a locking stud and a first locking knob. The locking stud includes a stud head and a stud rod connected to each other. The stud rod extends along the width direction of the main body and passes through the main body, the first clamping arm, and the second clamping arm. The first locking knob is movably disposed on the stud rod in the extending direction of the stud rod. One of the first clamping arm and the second clamping arm abuts against the first locking knob, and the other of the first clamping arm and the second clamping arm abuts against the stud head.

[0011] In some embodiments, the tracing mechanism includes an adjustment component and a tracing component, the adjustment component including: a pole, a mounting component, and a locking component. The pole includes a pole body and a mounting portion. One end of the pole body is connected to the main body, and the other end of the pole body is connected to the mounting portion. The mounting portion defines a rotating groove extending circumferentially along the mounting portion, and a rotating cavity communicating with the rotating groove is defined within the mounting portion. The outer circumferential surface of the mounting portion is provided with a first tooth. A mounting member is connected to the mounting portion in a manner that allows it to rotate circumferentially along the mounting portion. The mounting member is provided with a second tooth that engages with the first tooth. A tracking component is connected to the mounting component and is used to provide position information. A locking member passes through the rotating groove and is installed in the rotating cavity. The locking member passes through the mounting component and abuts against the mounting component. The locking member has a locked state and an unlocked state relative to the mounting component. When the locking member is in the locked state, the first tooth and the second tooth restrict the rotation of the mounting component. When the locking member is in the unlocked state, the first tooth and the second tooth are configured to jump under force, so that the mounting component can rotate relative to the mounting portion.

[0012] In some embodiments, the mounting member includes a rotatable mounting member and a mounting rod. The rotatable mounting member has a second tooth on one side and a third tooth on the other side. The mounting rod includes a connecting rod connected to the tracer assembly and a connecting portion connected to the connecting rod. The connecting portion has a fourth tooth that engages with the third tooth. When the locking member is in the locked state, the third tooth and the fourth tooth restrict the rotation of the connecting portion. When the locking member is in the unlocked state, the third tooth and the fourth tooth are configured to skip teeth under force, so that the connecting portion rotates relative to the rotatable mounting member in the circumferential direction of the connecting portion.

[0013] In some embodiments, the locking member includes a locking rod and a second locking knob. A portion of the locking rod passes through the rotating mounting member and the connecting portion, while another portion of the locking rod passes through the rotating groove and is mounted in the rotating cavity in a manner rotatable along the circumferential direction of the mounting portion. The second locking knob is located on the side of the connecting portion opposite to the rotating mounting member and abuts against the connecting portion. The second locking knob is connected to the locking rod in a manner movable along the length direction of the locking rod, and the second locking knob has a locked state and an unlocked state.

[0014] In some embodiments, the tracking component includes a tracking ball, a tracking plate, a buckle, and a knob. The tracking ball is mounted on the tracking plate and is used to provide position information. The tracking plate has a mounting hole. The mounting rod also includes a snap-fit ​​portion connected to the connecting rod. The snap-fit ​​portion is located on the side of the connecting rod away from the connecting portion and defines a slot. The buckle includes a buckle body and a claw connected to each other. The buckle body is disposed in the mounting hole, and the claw is disposed in the slot. The knob is rotatably disposed in the mounting hole and has a snap-fit ​​position and a disengaged position relative to the buckle. When the knob is in the snap-fit ​​position, it is connected to the claw and causes the claw to elastically deform so that the claw snaps into the slot. When the knob is in the disengaged position, it is separated from the claw so that the claw is released from the snap-fit.

[0015] In some embodiments, the knob includes a knob body, a positioning boss, and a driving part. The knob body is connected to the positioning boss. A first positioning platform and a second positioning platform are provided in the mounting hole. The positioning boss is located between the first positioning platform and the second positioning platform. When the knob is in the engaging position, the positioning boss abuts against the first positioning platform. When the knob is in the disengaged position, the positioning boss abuts against the second positioning platform. The driving part is connected to the knob body. The buckle body has a through hole. The driving part passes through the through hole and is located inside the claw in the inward and outward direction of the buckle body. When the knob is in the engaging position, the driving part is connected to the claw and presses the claw outward in the inward and outward direction of the buckle body. When the knob is in the disengaged position, the driving part is separated from the claw. Attached Figure Description

[0040] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

[0041] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between components; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0045] As a crucial component of orthopedic surgical navigation and positioning systems, the tracker is used to indicate the patient's spatial position during orthopedic surgery. In the surgical navigation system, the optical tracking device emits light, and the tracker's sphere reflects this light. By capturing the reflected light, the optical tracking device calculates the tracker's three-dimensional coordinates in space, thereby determining the position of the surgical site or instruments connected to it. During surgery, the tracker moves with the bones or surgical instruments. The optical tracking device can monitor the tracker's positional changes in real time, providing the surgeon with the real-time trajectory of the surgical site or instruments, enabling the surgeon to accurately monitor the progress of the operation.

[0046] Therefore, a secure connection and stable relative position between the tracker and the patient are essential for ensuring surgical precision. When the connection between the tracker and the patient becomes loose, the positional information tracked by the optical tracking device may deviate, leading to a decrease in surgical precision.

[0047] Current bone pin fixation tracers require at least two bone pins to be inserted into the bone tissue through the skin and muscles, and the tracer is then attached to the bone pins to achieve fixation.

[0048] However, bone needles are prone to deviation after insertion, making it difficult to install the tracer. When there is a large deviation in the bone needle, it is necessary to repeatedly remove and insert the bone needle, which prolongs the operation time and aggravates the patient's trauma.

[0049] To address the challenge of installing the tracer when bone pins are misaligned, embodiments of this application propose a bone pin-fixed tracer 100 that can accommodate bone pin positional deviations, thereby reducing the installation difficulty of the bone pin-fixed tracer 100.

[0050] The bone pin fixation tracer 100 of this application is described below with reference to the accompanying drawings.

[0051] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the bone pin fixation tracer 100 of this application embodiment includes: a clamping mechanism 1 and a tracer mechanism 2. The clamping mechanism 1 includes a clamping member 11, a clamping structure 12, and a clamping plate 13. The clamping member 11 includes a main body 111, a first clamping arm 112, and a second clamping arm 113. Both the first clamping arm 112 and the clamping plate 13 are used to abut against the first bone pin. The clamping plate 13 is correspondingly disposed with respect to the first clamping arm 112. The clamping plate 13 is rotatably disposed on the main body 111 so as to be able to tilt relative to the first clamping arm 112. The first clamping arm 112 is elastically connected to the main body 111 so as to be able to move closer to or away from the clamping plate 13. Both the clamping structure 12 and the second clamping arm 113 are used to abut against the second bone pin. The clamping structure 12 is disposed on the main body 111 and is correspondingly disposed with respect to the second clamping arm 113. The second clamping arm 113 is elastically connected to the main body 111 so as to be able to move closer to or away from the clamping plate 13. The tracking mechanism 2 is located in the main body 111 and is used to provide feedback on position information.

[0052] When installing the bone needle fixed type tracer 100 of this embodiment, the first bone needle is inserted into the gap between the clamping plate 13 and the first clamping arm 112. Since the clamping plate 13 is rotatably disposed on the main body 111 and can tilt relative to the first clamping arm 112, the end face of the clamping plate 13 can fit against the first bone needle, bringing the first clamping arm 112 close to the clamping plate 13, thereby clamping the first bone needle. The second bone needle is inserted into the gap between the second clamping arm 113 and the clamping structure 12, bringing the second clamping arm 113 close to the clamping structure, thereby clamping the second bone needle. Through the clamping action of the first and second bone needles, the bone needle fixed type tracer 100 is installed and fixed.

[0053] When disassembling the bone needle-fixed tracer 100 of this embodiment, the first clamping arm 112 is moved away from the clamping plate 13, thereby releasing the clamp on the first bone needle. The second clamping arm 113 is moved away from the clamping structure 12, thereby releasing the clamp on the second bone needle. By releasing the clamping action on the first and second bone needles, the bone needle-fixed tracer 100 is disassembled.

[0054] Since the clamping plate 13 is rotatable, it can flexibly adjust the angle formed between itself and the first clamping arm 112, thereby precisely fitting the first bone needle. This allows the first clamping arm 112 and the clamping plate 13 to stably hold the bone needle, avoiding instability caused by mismatched angles. This enables the adaptation to the positional deviation of the first bone needle, thereby reducing the installation difficulty of the bone needle fixed tracer 100.

[0055] Moreover, since the clamp 13 is rotatable, it can contact the first bone needle at a suitable angle, and the contact area between the clamp 13 and the first bone needle can be optimized so that the clamping force generated between the clamp 13 and the first clamping arm 112 can be evenly distributed on the surface of the first bone needle, thereby reducing the dispersion of clamping force and improving the stability of the first bone needle fixation.

[0056] Furthermore, different types of bone pins are used in different orthopedic surgeries depending on the patient's bone growth and the type of bone injury. By making the splint 13 rotatable, the clamping mechanism 1 can clamp multiple types of bone pins, thereby increasing the versatility of the bone pin fixation tracer 100 in this embodiment.

[0057] It should be noted that the "first" and "second" in "first bone needle" and "second bone needle" are only for distinguishing the two bone needles and do not imply the order in which the bone needles are inserted into the bone tissue. The first bone needle can be inserted into the bone tissue before the second bone needle, or the first bone needle can be inserted into the bone tissue after the second bone needle.

[0058] In some embodiments, the clamping mechanism 1 includes a rotating shaft disposed on the main body 111. The rotating shaft extends along the length direction a of the main body and passes through the clamping plate 13 along the length direction a of the main body. The clamping plate 13 is rotatably disposed around the length direction a of the main body.

[0059] As some examples, the length direction 'a' of the main body is as follows: Figure 4 The arrow at point a indicates this.

[0060] By rotatably arranging the clamping plate 13 around the length direction a of the main body, the clamping plate 13 can flexibly adjust the angle formed between itself and the first clamping arm 112, thereby accurately fitting the first bone needle and enabling the clamping plate 13 to contact the first bone needle at a suitable angle.

[0061] In some other embodiments, the clamping mechanism 1 includes a rotating shaft disposed on the main body 111. The rotating shaft extends along the height direction b of the main body and passes through the clamping plate 13 along the height direction b of the main body. The clamping plate 13 is rotatably disposed around the height direction b of the main body.

[0062] As some examples, the height direction b of the main body is as follows: Figure 4 The arrow at point b indicates this.

[0063] By making the clamping plate 13 rotatable about the height direction b of the main body, the clamping plate 13 can flexibly adjust the angle formed between itself and the first clamping arm 112, thereby accurately fitting the first bone needle and allowing the clamping plate 13 to contact the first bone needle at a suitable angle.

[0064] In some alternative embodiments, the shaft is fitted with a damping ring to generate damping and prevent the clamping plate 13 from rotating too fast.

[0065] In some alternative embodiments, the end face of the clamp 13 that abuts against the first bone needle is flat, so as to increase the fit between the clamp 13 and the first bone needle.

[0066] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the first clamping arm 112 includes a clamping arm body 1121 elastically connected to the main body 111 and an abutting portion 1122 disposed on the clamping arm body 1121. The abutting portion 1122 has a first end face 1124 and a second end face 1125. The first end face 1124 and the second end face 1125 intersect to form an abutting edge 1126. The abutting edge 1126 is used to abut against the first bone needle and is disposed opposite to the clamping plate 13.

[0067] The contact area between the abutment edge 1126 and the first bone pin is small, resulting in point or near-point contact when the abutment edge 1126 comes into contact with the first bone pin. This allows for slight positional changes in the first bone pin relative to the abutment edge 1126, and the abutment edge 1126 can also undergo slight positional changes to accommodate positional deviations of the first bone pin in different directions. By adapting the positional deviations of the first bone pin to the abutment edge 1126, the installation difficulty of the bone pin-fixed tracer 100 is further reduced.

[0068] The clamping plate 13 is rotatably mounted on the main body 111 and can rotate according to the position of the first bone needle, thereby forming a better fitting angle with the first bone needle. The abutment edge 1126 can adapt to the positional deviation of the first bone needle in multiple directions. In this embodiment, the bone needle fixed tracer 100, through the cooperation of the abutment part 1122 and the clamping plate 13, can greatly improve the adaptability of the clamping mechanism 1 to the positional deviation of the first bone needle, thereby reducing the installation difficulty of the bone needle fixed tracer 100.

[0069] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the clamping structure 12 is a clamping groove 121 for clamping the second bone needle, and the clamping groove 121 is disposed opposite to the second clamping arm 113.

[0070] The opposing clamping groove 121 and the second clamping arm 113 can apply a clamping force to the second bone needle, so as to stably fix the second bone needle and thus securely clamp the second bone needle.

[0071] In other embodiments, the clamping structure 12 is a rotating plate, which is disposed opposite to the second bone needle. The rotating plate is rotatably disposed on the main body 111 so as to be able to tilt relative to the second clamping arm 113.

[0072] Because the rotating plate can rotate, it can flexibly adjust the angle formed between itself and the second clamping arm 113, thereby precisely fitting the second bone needle. This allows the second clamping arm 113 and the rotating plate to stably hold the bone needle, avoiding instability caused by mismatched angles. This allows for adaptation to the positional deviation of the second bone needle, thereby reducing the installation difficulty of the bone needle fixed tracer 100.

[0073] Moreover, since the rotating plate is rotatable, it can contact the second bone needle at a suitable angle, and the contact area between the rotating plate and the second bone needle can be optimized so that the clamping force generated between the rotating plate and the second clamping arm 113 can be evenly distributed on the surface of the second bone needle, thereby reducing the dispersion of clamping force and improving the stability of the second bone needle fixation.

[0074] Furthermore, by making the rotating plate rotatable, the clamping mechanism 1 can be further adapted to various types of bone needles, thereby further increasing the versatility of the bone needle fixing tracer 100 of this embodiment.

[0075] Combination Figure 3 and Figure 4 As shown, in some embodiments, in the width direction of the main body 111, the first clamping arm 112 and the second clamping arm 113 are located on both sides of the main body 111. One end of the main body 111 in the length direction is elastically connected to the first clamping arm 112 and defines a first groove 1123. The other end of the main body 111 in the length direction is elastically connected to the second clamping arm 113 and defines a second groove 1131.

[0076] When the first clamping arm 112 approaches the main body 111, the first clamping arm 112 deforms in the direction of the first groove 1123. The first groove 1123 provides space for the deformation of the first clamping arm 112 relative to the main body 111, thereby preventing the main body 111 from obstructing the deformation of the first clamping arm 112.

[0077] When the second clamping arm 113 approaches the main body 111, the second clamping arm 113 deforms in the direction of the second groove 1131. The second groove 1131 provides space for the deformation of the second clamping arm 113 relative to the main body 111, thereby preventing the main body 111 from obstructing the deformation of the second clamping arm 113.

[0078] The first clamping arm 112 and the second clamping arm 113 are respectively disposed on both sides of the main body 111, which can increase the space utilization of the clamping member 11. In addition, the first clamping arm 112 and the second clamping arm 113 are located on both sides of the main body 111, providing relatively independent space for their respective movements, thereby avoiding mutual interference between the movements of the first clamping arm 112 and the second clamping arm 113.

[0079] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the clamping mechanism 1 further includes a locking stud 14 and a first locking knob 15. The locking stud 14 includes a stud head 141 and a stud rod 142 connected to each other. The stud rod 142 extends along the width direction c of the main body and passes through the main body 111, the first clamping arm 112 and the second clamping arm 113. The first locking knob 15 is movably disposed on the stud rod 142 in the extending direction of the stud rod 142. One of the first clamping arm 112 and the second clamping arm 113 abuts against the first locking knob 15, and the other of the first clamping arm 112 and the second clamping arm 113 abuts against the stud head 141.

[0080] When the first locking knob 15 is tightened, the first clamping arm 112 and the second clamping arm 113 move closer to the main body 111 under the squeezing action of the first locking knob 15 and the stud head 141, clamping the first bone needle and the second bone needle. When the first locking knob 15 is loosened, the first clamping arm 112 and the second clamping arm 113 undergo elastic deformation and move away from the main body 111, thereby releasing the clamping of the first bone needle and the second bone needle.

[0081] By setting the first locking knob 15, the position adjustment of the first clamping arm 112 and the second clamping arm 113 is made easier. By adjusting the position of the first locking knob 15, the first clamping arm 112 and the second clamping arm 113 can be loosened and locked. The installation, adjustment and disassembly of the bone pin fixation tracer 100 of this embodiment can be completed quickly during surgery, saving surgical time.

[0082] By adjusting the tightness of the first locking knob 15, the clamping force of the first clamping arm 112 and the second clamping arm 113 on the bone needle can be adjusted, thereby increasing the clamping effect of the first clamping arm 112 on the first bone needle and increasing the clamping effect of the second clamping arm 113 on the second bone needle. Furthermore, by adjusting the clamping force of the first clamping arm 112 and the second clamping arm 113 on the bone needle, the clamping mechanism 1 can be made more adaptable to bone needles of different specifications and models, thus further improving the versatility of the clamping mechanism 1.

[0083] In some specific embodiments, the locking stud 14 and the first locking knob 15 are threaded together.

[0084] When the first locking knob 15 is tightened on the stud rod 142, the friction between the threads provides a stable locking force, enabling the first clamping arm 112 and the second clamping arm 113 to securely clamp the first bone needle and the second bone needle.

[0085] The locking stud 14 and the first locking knob 15 are threaded together, making the position adjustment of the first locking knob 15 easier. By rotating the first locking knob 15, the first clamping arm 112 and the second clamping arm 113 can be loosened and locked. This allows for the quick installation, adjustment and disassembly of the bone pin fixation tracer 100 in this embodiment during surgery, saving surgical time.

[0086] In some alternative embodiments, the first clamping arm 112 and the second clamping arm 113 are both clearance-fitted with the stud rod 142 so that the stud rod 142 can generate a wobbling amount relative to the first clamping arm 112 and the second clamping arm 113, thereby increasing the adjustment effect of the stud rod 142 on the first clamping arm 112 and the second clamping arm 113.

[0087] Combination Figure 7 , Figure 8 and Figure 13 As shown, in some embodiments, the tracing mechanism 2 includes an adjustment component 21 and a tracing component 22. The adjustment component 21 includes a pole 211, a mounting component 214, and a locking component 215.

[0088] The upright 211 includes a pole body 212 and a mounting part 213. One end of the pole body 212 is connected to the main body 111, and the other end of the pole body 212 is connected to the mounting part 213. The mounting part 213 defines a rotating groove 2131 extending circumferentially along the mounting part 213. A rotating cavity 2132 communicating with the rotating groove 2131 is defined inside the mounting part 213. A first tooth 2133 is provided on the outer peripheral surface of the mounting part 213.

[0089] The mounting member 214 is connected to the mounting part 213 in a manner that allows it to rotate in the circumferential direction of the mounting part 213. The mounting member 214 is provided with a second tooth 2142 that engages with the first tooth 2133. The tracer component 22 is connected to the mounting member 214 and is used to provide feedback position information.

[0090] The locking member 215 passes through the rotating groove 2131 and is installed in the rotating cavity 2132. The locking member 215 passes through the mounting member 214 and abuts against the mounting member 214. The locking member 215 has a locked state and an unlocked state relative to the mounting member 214. When the locking member 215 is in the locked state, the first tooth 2133 and the second tooth 2142 are used to restrict the rotation of the mounting member 214. When the locking member 215 is in the unlocked state, the first tooth 2133 and the second tooth 2142 are configured to skip teeth when subjected to force, so that the mounting member 214 rotates relative to the mounting part 213.

[0091] The first tooth portion 2133 and the second tooth portion 2142 both include multiple engaging teeth. The first tooth portion 2133 and the second tooth portion 2142 are configured to be able to jump teeth under force, which means that the engaging teeth of the first tooth portion 2133 separate from the engaging teeth of the currently mating second tooth portion 2142 and engage with the engaging teeth at other positions of the second tooth portion 2142.

[0092] One end of the rod 212 is connected to the main body 111, which can be integrally formed or separately connected; this embodiment does not impose any restrictions.

[0093] When the angle of the tracer component 22 needs to be adjusted, the locking member 215 is in the unlocked state, and an external force is applied to the mounting member 214, causing the mounting member 214 to rotate relative to the mounting portion 213, thereby allowing the tracer component 22 to rotate circumferentially along the mounting portion 213. After the angle of the tracer component 22 is adjusted, the locking member 215 is locked to restrict the rotation of the mounting member 214 relative to the mounting portion 213.

[0094] When the locking member 215 is in the unlocked state, the first tooth 2133 and the second tooth 2142 are configured to skip teeth under force. The interlocking action between the first tooth 2133 and the second tooth 2142 provides a certain resistance, preventing the mounting member 214 from rotating arbitrarily when no external force is applied, thus ensuring the stability of the tracer assembly 22. When position adjustment is required, a certain external force needs to be applied to cause the first tooth 2133 and the second tooth 2142 to skip teeth. The resistance between the first tooth 2133 and the second tooth 2142 prevents angle changes caused by operator error. Furthermore, the skipping function of the first tooth 2133 and the second tooth 2142 allows the mounting member 214 to be quickly adjusted to different angular positions, improving the operating efficiency of the tracer mechanism 2.

[0095] When the locking member 215 is in the locked state, the first tooth 2133 and the second tooth 2142 restrict the rotation of the mounting member 214 relative to the mounting part 213, thereby increasing the stability of the tracer assembly 22.

[0096] The locking component 215 passes through the rotating groove 2131 and is installed in the rotating cavity 2132. It also passes through the mounting component 214 and abuts against the mounting component 214, thereby enhancing the overall structural stability of the adjustment component 21, making the mounting component 214 more stable during rotation, and improving the tracking accuracy of the tracer component 22.

[0097] Combination Figure 7 , Figure 11 and Figure 12 In some embodiments, the mounting member 214 includes a rotating mounting member 2141 and a mounting rod 2144. The rotating mounting member 2141 has a second tooth 2142 on one side and a third tooth 2143 on the other side. The mounting rod 2144 includes a connecting rod 2147 connected to the tracer assembly 22 and a connecting portion 2148 connected to the connecting rod 2147. The connecting portion 2148 has a fourth tooth 2149 that engages with the third tooth 2143. When the locking member 215 is in the locked state, the third tooth 2143 and the fourth tooth 2149 are used to restrict the rotation of the connecting portion 2148. When the locking member 215 is in the unlocked state, the third tooth 2143 and the fourth tooth 2149 are configured to skip teeth when subjected to force, so that the connecting portion 2148 can rotate relative to the rotating mounting member 2141 in the circumferential direction of the connecting portion 2148.

[0098] Both the third tooth 2143 and the fourth tooth 2149 include multiple engaging teeth. The third tooth 2143 and the fourth tooth 2149 are configured to be able to jump teeth under force, which means that the engaging teeth of the third tooth 2143 separate from the engaging teeth of the currently mating fourth tooth 2149 and engage with the engaging teeth at other positions of the fourth tooth 2149.

[0099] When the angle of the tracer component 22 needs to be adjusted, the locking member 215 is in the unlocked state, and an external force is applied to the rotating mounting member 2141 to rotate relative to the mounting portion 213, thereby allowing the tracer component 22 to rotate circumferentially along the mounting portion 213. An external force is applied to the connecting portion to rotate the connecting portion 2148 relative to the rotating mounting member 2141, thereby allowing the tracer component 22 to rotate circumferentially along the connecting portion 2148.

[0100] In this embodiment, the mounting component 214 adjusts the tracer component 22 in multiple directions, enabling the tracer component 22 to adapt to complex usage situations, thereby allowing the tracer component 22 to meet diverse usage needs and improve the tracer accuracy of the tracer component 22.

[0101] When the locking member 215 is in the unlocked state, the third tooth 2143 and the fourth tooth 2149 are configured to skip teeth under force. The interlocking action between the third tooth 2143 and the fourth tooth 2149 provides a certain resistance, preventing the mounting member 214 from rotating arbitrarily when no external force is applied, thus ensuring the stability of the tracer assembly 22. When position adjustment is required, a certain external force needs to be applied to cause the third tooth 2143 and the fourth tooth 2149 to skip teeth. The resistance between the third tooth 2143 and the fourth tooth 2149 prevents angle changes caused by operator error. Furthermore, the skipping function of the third tooth 2143 and the fourth tooth 2149 allows the mounting member 214 to be quickly adjusted to different angular positions, improving the operating efficiency of the tracer mechanism 2.

[0102] When the locking member 215 is in the locked state, the third tooth 2143 and the fourth tooth 2149 restrict the rotation of the mounting member 214 relative to the mounting part 213, thereby increasing the stability of the tracer assembly 22.

[0103] Combination Figure 7 and Figure 10 As shown, in some embodiments, the locking member 215 includes a locking rod 2151 and a second locking knob 2152. A portion of the locking rod 2151 passes through the rotating mounting member 2141 and the connecting portion 2148, and another portion of the locking rod 2151 passes through the rotating groove 2131 and is mounted in the rotating cavity 2132 in a manner that allows it to rotate in the circumferential direction of the mounting portion 213. The second locking knob 2152 is located on the side of the connecting portion 2148 opposite to the rotating mounting member 2141 and abuts against the connecting portion 2148. The second locking knob 2152 is connected to the locking rod 2151 in a manner that allows it to move along the length direction of the locking rod 2151. The second locking knob 2152 has a locked state and an unlocked state.

[0104] The second locking knob 2152 is connected to the locking rod 2151 in a manner that allows it to move along the length of the locking rod 2151. The second locking knob 2152 has a locked state and an unlocked state. When the second locking knob 2152 is in the locked state, it exerts a large compressive force on the rotating mounting member 2141, the mounting part 213, and the connecting part 2148, thereby locking the first tooth 2133 and the second tooth 2142 together, and locking the third tooth 2143 and the fourth tooth 2149 together, thereby restricting the rotation of the rotating mounting member 2141 relative to the mounting part 213 and restricting the rotation of the connecting part 2148 relative to the rotating mounting member 2141.

[0105] When the second locking knob 2152 is in the unlocked state, the second locking knob 2152 exerts a small compressive force on the rotating mounting member 2141, the mounting part 213, and the connecting part 2148. The engagement strength between the first tooth 2133 and the second tooth 2142 is small, and the engagement strength between the third tooth 2143 and the fourth tooth 2149 is also small. This allows the rotating mounting member 2141 to rotate relative to the mounting part 213 under force, and also allows the connecting part 2148 to rotate relative to the rotating mounting member 2141 under force.

[0106] Since the locking rod 2151 passes through the rotating groove 2131 and can rotate within the rotating cavity 2132, when adjusting the position and angle of the tracer component 22, first turn the second locking knob 2152 to the unlocked state. At this time, the mounting component 214 and the connecting part 2148 can be rotated flexibly. After adjusting to the appropriate position, tighten the second locking knob 2152 to restore all components to the locked state, thereby achieving precise adjustment and fixation of the position and angle of the tracer component 22.

[0107] The locking rod 2151 passes through the rotating mounting part 2141, the connecting part 2148, and the rotating cavity 2132 of the mounting part 213, forming a stable connection structure. This enhances the overall structural stability of the adjustment assembly 21, makes the mounting part 214 more stable during rotation, and improves the tracking accuracy of the tracer assembly 22.

[0108] In some specific embodiments, the second locking knob 2152 is threadedly connected to the locking rod 2151.

[0109] The second locking knob 2152 is threadedly connected to the locking rod 2151, providing a reliable locking function. Through this threaded connection, the second locking knob 2152 can stably perform locking and unlocking operations on the locking rod 2151, and maintains stability for a long time in the locked state, preventing loosening and thus improving the reliability of the tracer mechanism 2.

[0110] like Figure 7 As shown, in some optional embodiments, the adjusting assembly 21 further includes a spring 216, which rests between the rotating mounting member 2141 and the connecting portion 2148. The spring 216 is used to drive the rotating mounting member 2141 and the connecting portion 2148 away from each other when the second locking knob 2152 is in the unlocked state.

[0111] When adjusting the tracer assembly 22, the elastic force of the spring 216 can move the rotating mounting part 2141 and the connecting part 2148 away from each other, thereby further reducing the engagement strength between the third tooth 2143 and the fourth tooth 2149. This allows the operator to control the rotation between the rotating mounting part 2141 and the connecting part 2148 by applying a small external force, thus reducing the difficulty of adjusting the tracer assembly 22.

[0112] Combination Figure 7 and Figure 9 As shown, the adjustment assembly 21 also includes a rotating body 217, which is rotatably disposed in the rotating cavity 2132. The rotating body 217 is provided with a mounting groove 2171, and the locking rod 2151 extends into the mounting groove 2171 and is connected to the rotating body 217.

[0113] The rotating body 217 provides a support structure for the locking rod 2151 within the rotating cavity 2132, thereby making the locking rod 2151 more stable within the rotating cavity 2132. The cooperation between the rotating body 217 and the rotating cavity 2132 reduces the swaying of the locking rod 2151 in the direction inside and outside the rotating cavity 2132, thus making the tracer assembly 22 more stable.

[0114] The rotating body 217 is rotatably disposed within the rotating cavity 2132, providing more stable support for the rotation of the locking rod 2151. When adjusting the angle of the tracer assembly 22, the rotating body 217 ensures that the locking rod 2151 rotates along a predetermined trajectory, preventing the locking rod 2151 from jamming or deviating during rotation, and reducing the difficulty for operators during the adjustment process.

[0115] Combination Figure 13 , Figure 14 , Figure 15 and Figure 16As shown, in some embodiments, the tracking component 22 includes a tracking ball 221, a tracking plate 222, a latch 223, and a knob 224. The tracking ball 221 is mounted on the tracking plate 222 and is used to provide position information. The tracking plate 222 is provided with a mounting hole 2221. The mounting rod 2144 also includes a latching portion 2145 connected to the connecting rod 2147. The latching portion 2145 is located on the side of the connecting rod 2147 away from the connecting portion 2148 and defines a slot 2146. The latch 223 includes interconnected components. The buckle body 2231 and the claw 2232 are provided. The buckle body 2231 is provided in the mounting hole 2221, and the claw 2232 is provided in the slot 2146. The knob 224 is rotatably provided in the mounting hole 2221. The knob 224 has a snap-in position and a de-snap position relative to the buckle 223. When the knob 224 is in the snap-in position, it is connected to the claw 2232 and causes the claw 2232 to elastically deform so that the claw 2232 snaps into the slot 2146. When the knob 224 is in the de-snap position, it separates from the claw 2232 so that the claw 2232 is released from the snap-in position.

[0116] When it is necessary to install the tracer component 22 onto the adjustment component 21, align the buckle body 2231 of the buckle 223 with the mounting hole 2221 and the claw 2232 with the slot 2146. The tracer component 22 can then be quickly placed on the mounting rod 2144, so that the knob 224 is in the snap-fit ​​position. The knob 224 is connected to the claw 2232, and the claw 2232 is elastically deformed so that the claw 2232 snaps into the slot 2146, thereby installing the tracer component 22 onto the adjustment component 21.

[0117] When it is necessary to separate the tracer component 22 from the adjustment component 21, the knob 224 is placed in the separated position, the knob 224 is separated from the claw 2232, so that the claw 2232 is released from the engagement, and the tracer component 22 is removed from the adjustment component, thereby realizing the separation of the tracer component 22 from the adjustment component 21.

[0118] By setting the knob 224, the difficulty of installing and removing the tracer component 22 is reduced, making the installation and removal process of the tracer component 22 simple and quick.

[0119] Combination Figure 13 , Figure 14 , Figure 15 and Figure 16As shown, in some embodiments, the knob 224 includes a knob body 2241, a positioning boss 2242, and a driving part 2243. The knob body 2241 is connected to the positioning boss 2242. A first positioning platform 2222 and a second positioning platform 2223 are provided in the mounting hole 2221. The positioning boss 2242 is located between the first positioning platform 2222 and the second positioning platform 2223. When the knob 224 is in the engaged position, the positioning boss 2242 abuts against the first positioning platform 2222. When the knob 224 is in the disengaged position, the positioning boss 2242 abuts against the first positioning platform 2222. 42 abuts against the second positioning platform 2223; the driving part 2243 is connected to the button body 2241, the buckle body 2231 is provided with a through hole 2233, the driving part 2243 passes through the through hole 2233, and is located inside the claw 2232 in the inner and outer directions of the buckle body 2231. When the knob 224 is in the engaging position, the driving part 2243 is connected to the claw 2232 and presses the claw 2232 outward in the inner and outer directions of the buckle body 2231. When the knob 224 is in the disengaged position, the driving part 2243 is separated from the claw 2232.

[0120] The first positioning platform 2222 and the second positioning platform 2223 define the engaging and disengaged positions of the knob 224. When the knob 224 is in the engaging position, the positioning boss 2242 abuts against the first positioning platform 2222, ensuring that the knob 224 is in the correct locked position. At this time, the drive unit 2243 can stably push the claw 2232 outward, so that the claw 2232 is firmly engaged in the slot 2146, thereby ensuring the reliability of the connection between the tracer component 22 and the mounting rod 2144. When the knob 224 is in the disengaged position, the positioning boss 2242 abuts against the second positioning platform 2223, clearly indicating to the operator that the knob 224 is in the unlocked state. The claw 2232 separates from the slot 2146, facilitating the disassembly or adjustment of the tracer component 22.

[0121] When the drive unit 2243 is in the latching position, it connects with the latch 2232 and presses the latch 2232 outward, thereby enabling the latch 2232 to generate sufficient latching force, thus making the latch 2232 firmly latched in the latching slot 2146, so that the latch 2232 is not easy to disengage from the latching slot 2146, thereby improving the stability of the tracer component 22 during operation, and ensuring that the tracer ball 221 can accurately feed back position information.

[0122] When the knob 224 is in the disengaged position, the drive unit 2243 separates from the claw 2232, and the claw 2232 can be smoothly released from the latching state. This makes the disassembly process of the tracer component 22 simple and quick.

[0123] The drive unit 2243 passes through the through hole 2233 of the buckle body 2231 and is located inside the claw 2232, thereby making full use of the space inside the buckle body 2231, making the structure of the tracer component 22 more compact and facilitating the miniaturization of the tracer component 22.

[0124] Combination Figure 13 and Figure 14 As shown, in some specific embodiments, the tracer assembly 22 further includes a retaining ring 225. The tracer plate 222 is provided with a positioning groove 2224. One end of the positioning groove 2224 forms an opening. The tracer ball 221 is disposed in the positioning groove 2224 through the opening. The retaining ring 225 is connected to the tracer plate 222 and covers the opening of the positioning groove 2224. The retaining ring 225 is connected to the tracer ball 221.

[0125] The design of the positioning groove 2224 with one end open makes it easy to place the tracer ball 221 in it, while the retaining ring 225 covers the opening and is connected to the tracer ball 221, which can effectively prevent the tracer ball 221 from falling out of the positioning groove 2224, so that the tracer ball 221 can be stably located in the positioning groove 2224.

[0126] In some specific embodiments, the tracer plate 222 is provided with a locking protrusion and an unlocking protrusion. When the knob 224 is in the latched position, the knob body 2241 points to the locking protrusion. When the knob 224 is in the disengaged position, the knob body 2241 points to the unlocking protrusion.

[0127] The locking and unlocking protrusions provide clear operational guidance for operators. By observing whether the knob body 2241 points to the locking or unlocking protrusion, operators can quickly and intuitively determine the current position of the knob 224, thereby improving the accuracy of operation.

[0128] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
