Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0035] In order to solve the problems of troublesome operation and high cost of the existing guider when in use, the utility model provides a guider.

[0036] like Figures 1 to 6As shown, the guide comprises a target component 1 and a calibration component 2. The target component 1 is provided with a clamping portion 10. The calibration component 2 comprises a calibration portion 20 and a locking portion 30. The locking portion 30 is provided at the end of the calibration portion 20, and the locking portion 30 has a locking position in which the locking portion 10 is buckled and an unlocking position in which the locking portion 10 is separated.

[0037] In this embodiment, the calibration component 2 is detachably mounted on the engaging portion 10 of the target component 1. In actual use, the locking portion 30 is firstly buckled with the engaging portion 10, and the calibration component 2 is fixedly mounted on the target component 1. Then, after the calibration portion 20 is used to perform a CT (computed tomography) scan to establish the position mapping relationship of the guide, the calibration portion 20 is removed, and then the puncture needle and other structures are installed on the guide to perform the operation. Compared with the structure in the prior art in which the calibration portion 20 is fixedly set on the target component 1, the guide in this embodiment does not need to be replaced with a new target component 1 when in use. During the entire operation, the same target component 1 can be used to complete the entire process of CT scanning and surgical navigation. In this application, the calibration component 2 can be quickly installed on the target component 1, which can not only simplify the operation process of the operation and shorten the operation time, but also greatly reduce the cost of the guide during use.

[0038] In one embodiment, the locking portion 30 includes a plug-in portion 31 and a limiting portion 32. The plug-in portion 31 is disposed at the end of the calibration portion 20, and the plug-in portion 31 is used to buckle with the engaging portion 10, and the plug-in portion 31 has a locked position and an unlocked position. The limiting portion 32 is connected to the plug-in portion 31, and the limiting portion 32 drives the plug-in portion 31 to switch between the locked position and the unlocked position under the action of an external force. The plug-in portion 31 is buckled with the engaging portion 10, and the calibration component 2 can be installed on the target component 1, so that the plug-in portion 31 is in the locked position. The operator only needs to apply an external force to quickly install the plug-in portion 31 on the target component 1, or unlock the plug-in portion 31 to the unlocked position. The operator can switch the plug-in portion 31 between the locked position and the unlocked position by applying an external force, and the operation steps of using the guide are simpler, and the installation and removal process of the guide is also simpler and faster. The operator does not need to use other tools, and the guide can effectively reduce the risk of parts falling during operation. In this embodiment, the plug-in portion 31 is vertically disposed at the end of the marking portion 20 .

[0039] like Figures 3 to 6 As shown, in one embodiment, the limiting portion 32 includes a first limiting member 321, a locking tongue 322 and an elastic member 323. The first limiting member 321 is disposed on the plug-in portion 31. When the plug-in portion 31 is in the locked position, the first limiting member 321 stops at the first end of the engaging portion 10. The locking tongue 322 moves in a first direction (such as Figure 1The first stopper 321 and the stopper 322 on the lock tongue 322 act together on the opposite ends of the clamping part 10, clamping the clamping part 10 between the first stopper 321 and the stopper 322. The first stopper 321 and the lock tongue 322 have a double stop effect, ensuring that the limiter 32 will not move along the first direction, ensuring that the buckling between the plug-in part 31 and the clamping part 10 is more stable, and is conducive to improving the stability of the calibration part 20.

[0040] like Figure 6 As shown, the elastic member 323 is arranged along a second direction (eg, Figure 1 The elastic member 323 is retracted in the direction indicated by the arrow Y in the middle, specifically the length direction of the elastic member 3, and the two ends of the elastic member 323 are respectively against the plug-in portion 31 and the lock tongue 322. The elastic member 323 can provide elasticity for the lock tongue 322 to rotate relative to the plug-in portion 31. When the plug-in portion 31 and the clamping portion 10 need to be buckled, the elastic member 323 stretches to push up the lock tongue 322 along the second direction, so that the stop protrusion 3222 stops at the second end of the clamping portion 10, and the plug-in portion 31 is locked in the locking position. When the plug-in portion 31 and the clamping portion 10 need to be unlocked, the operator applies an external force to overcome the elastic effect of the elastic member 323, and the lock tongue 322 can be easily rotated, so that the stop protrusion 3222 is separated from the clamping portion 10, and the plug-in portion 31 is unlocked to the unlocking position. The elastic member 323 has a certain buffering effect, and the elastic member 323 can reduce the impact force between the lock tongue 322 and the clamping portion 10 when unlocking, which is conducive to extending the service life of the guide.

[0041] like Figure 3As shown, in one embodiment, the first limiting member 321 includes a locking pin 3211. The plug-in portion 31 is provided with a mounting cavity 311 penetrating along the first direction, and the side wall of the mounting cavity 311 is provided with a first limiting hole 3111. The locking tongue 322 is provided with a second limiting hole 3221. The locking pin 3211 penetrates the first limiting hole 3111 and the second limiting hole 3221, and at least one end of the locking pin 3211 protrudes from the surface of the plug-in portion 31. When the plug-in portion 31 is in the locked position, the end of the locking pin 3211 stops at the first end of the engaging portion 10. At least one end of the locking pin 3211 protrudes from the surface of the plug-in portion 31 and stops at the first end of the engaging portion 10, so that the locking pin 3211 can effectively prevent the limiting portion 32 from sliding along the first direction. The locking pin 3211 penetrates the first limiting hole 3111 and the second limiting hole 3221, forming a rigid connection between the plug-in portion 31 and the locking tongue 322. This rigid connection is more stable, and can effectively ensure that the locking tongue 322 is stably installed on the plug-in portion 31, and ensure that the locking tongue 322 will not loosen after multiple uses, which is conducive to improving the stability of the guide during surgery or scanning alignment. When installing the locking tongue 322, it is only necessary to align the second limiting hole 3221 with the first limiting block, and insert the locking tongue 322 into the first limiting hole 3111 and the second limiting hole 3221. The assembly and disassembly process of the locking tongue 322 is simple, and the locking tongue 322 is easy to replace.

[0042] like Figure 5 As shown, in one embodiment, the locking tongue 322 is rotatably connected to the locking pin 3211, and the stop protrusion 3222 is rotated and stopped at the second end of the engaging portion 10 by the elastic action of the elastic member 323. The locking tongue 322 is rotatable, and the locking tongue 322 can be automatically locked at the second end of the engaging portion 10 by the action of the elastic member 323, without the operator having to perform additional operations, which greatly simplifies the installation process of the calibration component 2. The use of the guide is simpler and more convenient, and the operation process of the surgery is faster.

[0043] In one embodiment, at least one side of the stop protrusion 3222 along the second direction is provided with a guide slope 3223. The guide slope 3223 provides a guiding effect during the locking and unlocking process, and the stop protrusion 3222 can be inserted into and away from the engaging portion 10 along the guide slope 3223, ensuring that the stop protrusion is installed correctly. The guide slope 3223 can also reduce the friction between the stop protrusion and the engaging portion 10, making the process of inserting and removing the stop protrusion 3222 from the engaging portion 10 smoother and smoother, thereby reducing the wear rate between the stop protrusion 3222 and the engaging portion 10, which is conducive to extending the service life of the guide. Specifically, when the calibration component 2 is unlocked from the target component 1, the operator can press the guide slope 3223 along the second direction to make the stop protrusion lower than the engaging portion 10, and then apply an external force along the first direction to disassemble the calibration component 2 and move it away from the target component 1.

[0044] In one embodiment, the plug-in portion 31 includes a plug-in column 312 and a plug-in block 313 distributed in sequence along the second direction. The plug-in column 312 is located at the end of the calibration portion 20. The plug-in block 313 is buckled with the clamping portion 10. The mounting cavity 311 is located on the plug-in block 313, and the stop protrusion 3222 protrudes from the plug-in block 313 along the second direction. The plug-in block 313 can be accurately aligned with and inserted into the clamping portion 10 to ensure the accuracy of the buckling process of the plug-in block 313 and the clamping portion 10. The stop protrusion 3222 protrudes from the plug-in block 313 along the second direction to ensure that when the plug-in portion 31 is in the locked position, the stop protrusion 3222 can stop the second end of the clamping portion 10 from shaking, thereby ensuring that the plug-in portion 31 is stably and reliably installed on the target assembly 1.

[0045] In one embodiment, a T-slot is provided on the engaging portion 10, and a T-block adapted to the T-slot is provided on the plug-in block 313, and both the T-slot and the T-block extend along the first direction. After the T-block is adapted to the T-slot, the plug-in block 313 can be limited in the second direction, further ensuring the stability of the calibration component 2. Specifically, the T-slot includes an opening section and a plug-in section that are interconnected, the length of the opening section is less than the length of the plug-in section, a boss is provided at the end of the T-block, the boss is limited in the plug-in section, the boss and the outer wall of the mounting cavity 311 form a groove, and the opening section is limited in the groove.

[0046] Alternatively, a T-shaped slot is provided on the plug-in block 313, and a T-shaped block matched with the T-shaped slot is provided on the engaging portion 10, and both the T-shaped slot and the T-shaped block extend along the first direction.

[0047] In one embodiment, a limiting groove is provided in the plug post 312, the limiting groove is communicated with the installation cavity 311, one end of the elastic member 323 abuts against the groove bottom of the limiting groove, and the other end extends into the installation cavity 311 and abuts against the locking tongue 322. In this embodiment, the elastic member 323 can be a spring, but is not limited thereto, and this embodiment is not the only limitation.

[0048] In one embodiment, the calibration part 20 includes a calibration plate 21, and both sides of the calibration plate 21 in the width direction are provided with avoidance gaps 211. When a guide wire has been inserted into the patient, the avoidance gaps 211 can avoid the guide wire on the patient, effectively reducing the negative impact of the guide wire on the calibration plate 21 for registration, which is conducive to improving the accuracy and precision of the scanning registration, and effectively avoiding the situation where the registration fails and needs to be re-scanned and registered.

[0049] The calibration plate 21 can be set as a square plate. The calibration plate 21 is provided with a plurality of calibration holes, which is convenient for establishing the position mapping relationship of the guide during the CT scanning process. It can be understood that the calibration plate 21 can also be a circular plate, a triangular plate, a trapezoidal plate, an elliptical plate or other special-shaped plates, and the calibration plate 21 is provided with calibration holes.

[0050] like Figure 2 As shown, the target assembly 1 includes a target bracket 40 and a sleeve assembly 50. The clamping portion 10 is located on the target assembly 1, and the target bracket 40 is installed on the sleeve assembly 50 by connecting screws or connecting pins. The target bracket 40 includes four pillars, and a reflective ball is provided at the end of each pillar, and the reflective ball is used for image recognition. In the present application, the calibration component 2 is detachably mounted on the target bracket 40, and there is no need to replace a new target bracket 40 and a reflective ball, which is conducive to reducing the cost of the guide during use. The sleeve assembly 50 includes a positioning sleeve 51 and a mounting sleeve 52. A positioning hole is provided on the positioning sleeve 51, and the positioning hole is located on the inner side of the positioning sleeve 51 and extends along the axial direction of the positioning sleeve 51. The mounting sleeve 52 is installed in the positioning hole and can rotate along its own axis. A connecting portion 511 is provided on the positioning sleeve 51, and the connecting portion 511 is at least used to connect the positioning sleeve 51 to a predetermined structure, such as a surgical robot arm. The connection part 511 is provided with a sterile protection member 512. In actual use, a sterile film is sleeved on the connection part 511, and then the sterile film is fixed by the sterile protection member 512, which can play a role in sterile protection.

[0051] According to another aspect of the present invention, the present invention further discloses a surgical guide system, which includes a guide, and the guide is the guide in the above embodiment. Therefore, the surgical guide system in this embodiment includes all the technical effects of the above guide, and since the technical effects of the guide have been described in detail above, they will not be repeated here.

[0052] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0053] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0054] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
