[0028] As Figure 1 and Figure 2 shown, an embodiment of the present application provides a surgical navigator, including: a base 100, a connection component, and a positioning component 500. The connection component includes a moving part 200, a first connection part 300, and a rotating part 400. The moving part 200 is disposed on the base 100 and has a first end 201 and a second end 202 opposite to each other along a first direction X. The first end 201 is movably disposed on the base 100 along the first direction X; the first connection part 300 is connected to the second end 202 and extends along a second direction Y. The rotating part 400 is connected to one end of the first connection part 300 away from the moving part 200 and is rotatably disposed relative to the first connection part 300 about an axis extending along the first direction X. The first direction X and the second direction Y intersect; the positioning component 500 is connected to the rotating part 400, and the positioning component 500 is used to obtain the position information of the target object.

[0029] In this embodiment, the moving part 200 is movably connected to the base 100 through the first end 201. The first end 201 is movable relative to the base 100 along the first direction X. The first connection part 300 is connected to the second end 202 and extends along the second direction Y. When the first end 201 of the moving part 200 moves along the first direction X, it can drive the first connection part 300 to move along the first direction X through the second end 202. The positioning component 500 is connected to the first connection part 300 through the rotating part 400, so that the positioning component 500 can move along the first direction X to adjust the position of the positioning component 500 along the first direction X, facilitating the positioning component 500 to observe and obtain the position information of the target object. The rotating part 400 is connected to one end of the first connection part 300 away from the moving part 200, which can reduce the influence of the rotating part 400 and the positioning component 500 on the moving path of the moving part 200 when the moving part 200 moves relative to the base 100. The rotating part 400 is rotatably disposed relative to the first connection part 300 about an axis extending along the first direction X, enabling the positioning component 500 to rotate about an axis extending along the first direction X, which is beneficial to adjusting the observation angle of the positioning component 500 and facilitating the positioning component 500 to observe and obtain the position information of the target object.

[0030] The length of the base 100 along the first direction X defines the moving distance of the moving part 200. The distance between the first end 201 and the second end 202 of the moving part 200 and the moving distance of the moving part 200 define the movable range of the positioning component 500. The surgical navigator in this embodiment occupies the space in the first direction X, which is beneficial to reducing the volume of the surgical navigator, has a small requirement for occupying the space perpendicular to the first direction X, is beneficial to reducing the space occupied by the surgical navigator, and is easy to operate.

[0031] Optionally, the first direction X is the vertical direction. The moving part 200 moves along the first direction X to adjust the height of the positioning component 500, reducing the line-of-sight interference with the positioning component 500. The base 100 extends along the vertical direction, and the first end 201 and the second end 202 of the moving part 200 are arranged opposite to each other along the vertical direction, which is beneficial to reducing the occupation of the space in the horizontal direction.

[0032] Optionally, the first direction X is perpendicular to the second direction Y, the first direction X is the vertical direction, and the second direction Y is the horizontal direction.

[0033] As Figure 2 shown, in some alternative embodiments, the surgical navigator further includes a pitch adjustment component 600. The positioning component 500 is connected to the rotating part 400 through the pitch adjustment component 600. The plane where the first direction X and the second direction Y are located is the reference plane, and the pitch adjustment component 600 is rotatably arranged around the direction perpendicular to the reference plane.

[0034] In these alternative embodiments, the positioning component 500 is connected to the rotating part 400 through the pitch adjustment component 600. The pitch adjustment component 600 is used to adjust the pitch angle of the positioning component 500. The pitch adjustment component 600 is rotatably arranged around the direction perpendicular to the reference plane to adjust the viewing angle of the positioning component 500 and improve the positioning effect of the positioning component 500.

[0035] As Figure 3 and Figure 4 shown, in some alternative embodiments, the pitch adjustment component 600 includes a mounting seat 610 and a damping rotating shaft 620. The mounting seat 610 is connected to the rotating part 400, the damping rotating shaft 620 is connected to the mounting seat 610, and the axis of the damping rotating shaft 620 is perpendicular to the first direction X. The positioning component 500 is rotatably connected to the mounting seat 610 through the damping rotating shaft 620.

[0036] In these alternative embodiments, the damping rotating shaft 620 is connected to the mounting base 610, and the mounting base 610 is connected to the rotating part 400, so that the mounting base 610 and the damping rotating shaft 620 can rotate about an axis extending along the first direction X. The positioning assembly 500 is rotatably connected to the mounting base 610 through the damping rotating shaft 620, and the axial direction of the damping rotating shaft 620 is perpendicular to the first direction X, so that the positioning assembly 500 can rotate about the axial direction of the damping rotating shaft 620. The damping rotating shaft 620 has a rotational damping, which can provide a resistance to the positioning assembly 500 to prevent it from continuing to rotate, so as to fix the angle of the positioning assembly 500. When an external force is used to rotate the positioning assembly 500, the positioning assembly 500 can be rotated when the external force is greater than the resistance of the damping rotating shaft 620. When the external force is removed, the damping rotating shaft 620 has a rotational damping to fix the position of the positioning assembly 500, reducing the influence of the shaking of the positioning assembly 500 on the positioning effect.

[0037] Optionally, as Figure 3 and Figure 4 shown, when the first direction X is the vertical direction and the second direction Y is the horizontal direction, the axial direction of the damping rotating shaft 620 is perpendicular to the first direction X, that is, the axial direction of the damping rotating shaft 620 is the horizontal direction, and the positioning assembly 500 realizes the pitch angle adjustment around the axial direction of the damping rotating shaft 620. When the external force is removed, the resistance of the damping rotating shaft 620 is greater than the gravity of the positioning assembly 500, so as to fix the position of the positioning assembly 500.

[0038] As Figures 3 to 5 shown, in some alternative embodiments, the pitch adjustment assembly 600 further includes an adapter 630. The adapter 630 is rotatably connected to the damping rotating shaft 620, and the positioning assembly 500 is rotatably connected to the damping rotating shaft 620 through the adapter 630; a first limit pin 611 is provided on one side of the mounting base 610 facing the adapter 630, and a limit groove 631 is provided on one side of the adapter 630 facing the mounting base 610. The limit groove 631 includes two side walls 631a arranged at intervals along the first direction X, and at least part of the first limit pin 611 is located between the two side walls 631a. The first limit pin 611 is used to limit the rotation angle of the adapter 630.

[0039] In these optional embodiments, the adapter 630 is rotatably connected to the damping shaft 620, and the adapter 630 rotates around the damping shaft 620, that is, the rotation direction of the adapter 630 is perpendicular to the first direction X, and the positioning assembly 500 is connected to the adapter 630, so that the positioning assembly 500 can rotate the adapter 630 around the damping shaft 620. The mounting seat 610 and the adapter 630 are arranged opposite to each other, and a first limiting pin 611 is provided on the side of the mounting seat 610 facing the adapter 630, and a limiting groove 631 is provided on the side of the adapter 630 facing the mounting seat 610, and at least part of the first limiting pin 611 is located between the two side walls 631a. In the process of pitch adjustment of the positioning assembly 500, the first limiting pin 611 moves between the two side walls 631a, and the distance between the two side walls 631a is the pitch adjustment range of the positioning assembly 500. Optionally, the limiting groove 631 is an arc groove.

[0040] Optional, such as Figure 3 and Figure 4 As shown, the positioning assembly 500 is provided with a mounting plate 640 , the mounting plate 640 has a mounting hole 641 , and the adapter 630 is located in the mounting hole 641 .

[0041] Optional, such as Figure 6 As shown, the rotating part 400 includes a sleeve 410 and a rotating shaft 420 rotatably mounted in the sleeve 410. The sleeve 410 is connected to the first connecting part 300, and the sleeve 410 is provided with a first clamping groove 430; the outer peripheral side of the rotating shaft 420 is provided with a second clamping groove 440, and the first clamping groove 430 and the second clamping groove 440 are arranged opposite to each other. The rotating part 400 also includes a clamping piece 450, which is clamped in the first clamping groove 430 and the second clamping groove 440 to fix the rotating shaft 420 in the sleeve 410.

[0042] Optionally, the mounting seat 610 is connected to a side of the rotating shaft 420 facing away from the sleeve 410 .

[0043] like Figure 1 and 2 As shown, in some optional embodiments, the base 100 includes a movable chamber 110 extending along a first direction X, an opening 120 located at one end of the movable chamber 110 in the first direction X, and a slit 130 communicating with the movable chamber 110. The slit 130 extends along the first direction X and communicates with the opening 120; the first end 201 extends from the opening 120 into the movable chamber 110 and is movably arranged relative to the movable chamber 110 along the first direction X; the slit 130 is configured such that when the second end 202 is located in the movable chamber 110, the first connecting portion 300 is located in the slit 130; and the rotating portion 400 is connected to one end of the first connecting portion 300 away from the movable portion 200 and is located outside the movable chamber 110.

[0044] In these alternative embodiments, the first end 201 extends into the moving chamber 110 through the opening 120 and is capable of moving along the first direction X within the moving chamber 110. The slit 130 extends along the first direction X and communicates with the opening 120. The first end 201 drives the second end 202 to move towards the opening 120 along the first direction X. When the second end 202 extends into the moving chamber 110 through the opening 120, the first connecting portion 300 enters the slit 130 through the opening 120. The slit 130 is used to accommodate the first connecting portion 300. The first connecting portion 300 connects the second end 202 located within the moving chamber 110 through the slit 130. The slit 130 extends along the first direction X so that the second end 202 can continue to move along the first direction X within the moving chamber 110. At this time, the first connecting portion 300 moves along the first direction X within the slit 130. Providing a slit 130 that extends along the first direction X can increase the moving range of the moving portion 200. The rotating portion 400 is connected to one end of the first connecting portion 300 facing away from the moving portion 200 and is located outside the moving chamber 110, such that the positioning assembly 500 is located outside the moving chamber 110, which not only increases the movement range of the positioning assembly 500 but also helps to reduce the volume of the base 100.

[0045] As Figure 1 shown, in some alternative embodiments, a dust brush 140 is provided on the side of the base 100 facing the slit 130, and the dust brush 140 is used to cover the slit 130.

[0046] In these alternative embodiments, the dust brush 140 is used to cover the slit 130. The dust brush 140 covers the slit 130 to reduce dust and the like from entering the moving chamber 110 through the slit 130. The bristles of the dust brush 140 include a soft material. When the first connecting portion 300 enters the slit 130, the first connecting portion 300 presses against the dust brush 140 to bend the bristles to facilitate the movement of the first connecting portion 300 within the slit 130.

[0047] As Figure 2 shown, in some alternative embodiments, a rack 150 is provided in the moving chamber 110, and a one-way damping gear 210 is provided on the moving portion 200. The one-way damping gear 210 meshes with the rack 150, and the one-way damping gear 210 is configured to provide resistance to the moving portion 200 when the first end 201 moves in a direction away from the opening 120.

[0048] In these alternative embodiments, the one-way damping gear 210 is connected to the moving part 200. The one-way damping gear 210 meshes with the rack 150. During the movement of the moving part 200, the one-way gear is driven to move relative to the rack 150 and rotate. When the first end 201 moves towards the opening 120, the one-way damping gear 210 can rotate freely. When the first end 201 moves away from the opening 120, the one-way damping gear 210 provides resistance to the moving part 200. When the first direction X is the vertical direction and the height of the plane where the opening 120 is located is greater than the height of the plane where the first end 201 is located, when the first end 201 moves towards the opening 120 to raise the moving part 200, the one-way damping gear 210 can rotate freely to facilitate raising the positioning assembly 500. Due to the influence of gravity, when the first end 201 has a tendency to move away from the opening 120 and lower, the one-way damping gear 210 provides resistance to the moving part 200 to prevent the moving part 200 from lowering under the action of gravity, so that the positioning assembly 500 remains relatively stationary. When it is necessary to lower the height of the positioning assembly 500, the positioning assembly 500 is pushed by an external force. When the combination of the external force and gravity is greater than the resistance provided by the one-way damping gear 210 to the moving part 200, the moving part 200 can move downward under the action of the external force to adjust the height of the positioning assembly 500.

[0049] Optionally, as Figure 2 shown, the rack 150 extends along the first direction X so that the one-way damping gear 210 can remain meshed with the rack 150 when moving in the first direction X.

[0050] As Figure 2 shown, in some alternative embodiments, a slide rail 160 is provided in the moving chamber 110. The slide rail 160 extends along the first direction X. The moving part 200 is slidably connected to the slide rail 160. The moving part 200 is provided with a locking member 220. The locking member 220 is movably arranged in a direction close to or away from the slide rail 160 so that the locking member 220 abuts against the slide rail 160 or the locking member 220 is spaced apart from the slide rail 160. The locking member 220 is configured to lock the moving part 200 when the locking member 220 abuts against the slide rail 160.

[0051] In these optional embodiments, the moving part 200 is slidably connected to the slide rail 160, and the slide rail 160 extends along the first direction X to keep the moving part 200 along the first direction X when moving. The locking member 220 is fixedly connected to the moving part 200 so that the locking member 220 and the moving part 200 move synchronously, and the locking member 220 is movably arranged in a direction close to or away from the slide rail 160. When the locking member 220 abuts against the slide rail 160, a friction force is generated between the locking member 220 and the slide rail 160 to fix the position of the moving part 200 on the slide rail 160, thereby fixing the position of the positioning assembly 500 in the first direction X. When the position of the moving part 200 needs to be adjusted, the locking member 220 is spaced apart from the slide rail 160, and the moving part 200 can move relative to the slide rail 160.

[0052] like Figure 1 , Figure 7 and Figure 8 As shown, in some optional embodiments, the surgical navigator also includes a display mounting assembly, which includes a mounting sheet metal 700 and an adjustment assembly 800, wherein the mounting sheet metal 700 is used to mount the display 10, and the adjustment assembly 800 is installed on the side of the base 100 facing the opening 120, and the mounting sheet metal 700 is rotatably connected to the base 100 through the adjustment assembly 800, and the avoidance groove 801 is connected to the gap 130 and the movable chamber 110 through the opening 120, and the avoidance groove 801 is used to avoid the movable part 200 and the first connecting part 300.

[0053] In these optional embodiments, the adjustment component 800 is installed on the side of the base 100 facing the opening 120, the mounting sheet metal 700 is rotatably connected to the base 100 through the adjustment component 800, and the mounting sheet metal 700 can rotate around the base 100, so that the display 10 can rotate around the base 100. The positioning component 500 is used to obtain the position information of the target object and transmit it to the display area, and display it through the display 10.
