[0064] References to "one embodiment", "some embodiments" or "an embodiment" described in the specification of this application mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some other embodiments", "in some other embodiments", etc., which appear at different places in this specification, do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. In addition, in one or more embodiments, particular features, structures or characteristics may be combined in any suitable manner.

[0065] In order to illustrate the technical solution of the present application, a description is given below with reference to specific drawings and embodiments.

[0066] After the traditional camera device is inserted into the incision, the camera angle and range of the camera assembly are fixed, which cannot meet the requirements of minimally invasive surgery. The camera adjustment range is limited and the effect is poor.

[0067] In order to solve the above problems, the present application provides a camera device and an image acquisition system, which can adjust the camera range to better meet the requirements of minimally invasive surgery.

[0068] Please refer to Figures 1 to 5 , Figure 1 is a usage state diagram of an image acquisition system 1000 in one embodiment of the present application, Figure 2 yes Figure 1 A partial enlarged view of the middle A. Figure 3 yes Figure 1 The structural diagram of the camera device 100 in the image acquisition system 1000 is shown in FIG. Figure 4 yes Figure 3 The partial structural cross-sectional view of the camera device 100 is shown in FIG. Figure 5 yes Figure 4 A partial enlarged view of point B in the middle.

[0069] In a first aspect, an embodiment of the present application provides a camera device 100 for providing a surgical auxiliary field of view. The camera device 100 includes a first connecting member 10, a first rotating shaft 20, a camera assembly 30, an elastic member 40 and a traction assembly 50.

[0070] The first rotating shaft 20 is rotatably connected to the first connecting member 10, and the camera assembly 30 is fixedly connected to the first rotating shaft 20, so as to realize the rotatable connection between the camera assembly 30 and the first connecting member 10. For example, the camera assembly 30 and the first rotating shaft 20 can be connected by welding, bonding, clamping, screw connection or bolt connection.

[0071] Please refer to Figures 6 to 10 , Figure 6 yes Figure 3 The structural diagram of the adjusting member 52 in the camera device 100 is shown in FIG. Figure 7 yes Figure 3 The structural exploded view of the camera device 100 shown in FIG. Figure 8 yes Figure 7 A partial enlarged view of point C in the middle. Fig. 9 yes Figure 3 The structure of the camera device 100 is exploded from another perspective. Fig.10 yes Fig. 9 A partial enlarged view of point D in the middle.

[0072] One end of the elastic member 40 is connected to the first connecting member 10, and the other end is connected to the camera assembly 30. The elastic member 40 is used to apply a force around the axis of the first rotating shaft 20 and along the first direction to the camera assembly 30. After the elastic member 40 applies a force around the axis of the first rotating shaft 20 and along the first direction to the camera assembly 30, the camera assembly 30 and the first rotating shaft 20 can rotate together around the axis of the first rotating shaft 20 and along the first direction. Figure 5 The axis of the first rotating shaft 20 may be Figure 5 The dotted line in the figure, the axis of the first rotating shaft 20 can be parallel to the X direction in the figure, and the X direction, Y direction and Z direction in the figure can be the positive directions of the X axis, Y axis and Z axis in the rectangular coordinate system respectively.

[0073] The elastic member 40 may be a torsion spring, an elastic rubber strip, or an elastic metal strip. For example, the elastic member 40 is an elastic rubber strip, one end of which is fixed to the camera assembly 30, and the rubber strip is gradually wound around the first rotating shaft 20 along the second direction, so that the elastic member 40 can apply a force around the axis of the first rotating shaft 20 and along the first direction to the camera assembly 30. The second direction can be along Figure 5 The direction indicated by the arrow M.

[0074] The traction assembly 50 includes a traction member 51, which is wound around the first rotating shaft 20. By pulling the traction member 51, part of the traction member 51 can be detached from the first rotating shaft 20, and the camera assembly 30 can rotate around the axis of the first rotating shaft 20 and along the second direction, which is opposite to the first direction.

[0075] It can be understood that the traction member 51 can be a traction wire or a steel wire rope, and the traction member 51 is wound around the first rotating shaft 20 along the first direction.

[0076] When the traction member 51 is pulled, the camera assembly 30 and the first rotating shaft 20 rotate together around the axis of the first rotating shaft 20 and in the second direction, and part of the traction member 51 gradually detaches from the first rotating shaft 20. The elastic member 40 applies a force around the axis of the first rotating shaft 20 and in the first direction to the camera assembly 30 that gradually increases. For example, the rubber strip gradually wraps around the first rotating shaft 20 in the second direction.

[0077] When the traction member 51 is released, since the elastic member 40 is used to apply a force around the axis of the first rotating shaft 20 and along the first direction to the camera assembly 30, the camera assembly 30 and the first rotating shaft 20 rotate together around the axis of the first rotating shaft 20 and along the first direction, and the traction member 51 gradually wraps around the first rotating shaft 20 along the first direction.

[0078] When the camera device 100 provided in the embodiment of the present application is used, the patient 3000 can be placed on the operating table 2000 first, and then the camera assembly 30 can be extended into the newly added incision on the patient 3000 to provide the required additional field of view. When it is necessary to adjust the camera range of the camera assembly 30, the traction member 51 can be pulled as needed to make the camera assembly 30 rotate around the axis of the first rotating shaft 20 and in the second direction, or the traction member 51 can be loosened away from one end of the first rotating shaft 20 to make the camera assembly 30 rotate around the axis of the first rotating shaft 20 and in the first direction, thereby adjusting the camera range of the camera assembly 30.

[0079] From the above, it can be known that the camera device 100 provided in the embodiment of the present application, since the camera assembly 30 is rotatably connected to the first connecting member 10 through the first rotating shaft 20, one end of the elastic member 40 is connected to the first connecting member 10, and the other end is connected to the camera assembly 30, the elastic member 40 is used to apply a force around the axis of the first rotating shaft 20 and along the first direction to the camera assembly 30, and the traction member 51 is wrapped around the first rotating shaft 20, so by pulling the traction member 51, the traction member 51 can be detached from the first rotating shaft 20, and the camera assembly 30 can be rotated around the axis of the first rotating shaft 20 and along the second direction opposite to the first direction, so that the camera range of the camera assembly 30 can be adjusted, and the function of the camera assembly 30 to shoot at different angles can be realized, so as to better adapt to the requirements of minimally invasive surgery.

[0080] The camera device 100 provided in the embodiment of the present application has a simple structure, is easy to operate, requires a smaller surgical incision, and can achieve multi-directional free angle adjustment of the camera range of the camera assembly 30.

[0081] It should be noted that one first rotating shaft 20 may be provided. For example, the elastic member 40, the traction assembly 50 and the first rotating shaft 20 are located on the same side of the camera assembly 30. Alternatively, the first rotating shaft 20 passes through the camera assembly 30, and both ends of the first rotating shaft 20 protrude from the camera assembly 30, and the elastic member 40 and the traction assembly 50 are respectively provided on opposite sides of the camera assembly 30 or on the same side of the camera assembly 30. Alternatively, the camera assembly 30 passes through the first rotating shaft 20, and the elastic member 40 and the traction assembly 50 are respectively provided on opposite sides of the camera assembly 30 or on the same side of the camera assembly 30.

[0082] Alternatively, two first rotating shafts 20 are provided and the two first rotating shafts 20 are respectively provided on opposite sides of the camera assembly 30. The elastic member 40, the traction assembly 50 and one of the first rotating shafts 20 are located on the same side of the camera assembly 30, and the other first rotating shaft 20 is located on the other side of the camera assembly 30. Alternatively, the elastic member 40 and one of the first rotating shafts 20 are located on the same side of the camera assembly 30, and the traction assembly 50 and the other first rotating shaft 20 are located on the other side of the camera assembly 30.

[0083] Optionally, the first rotating shaft 20 may be provided with a through hole, the end of the traction member 51 is passed through the through hole, and the traction member 51 is wound around the first rotating shaft 20. This arrangement facilitates the connection of the traction member 51 with the first rotating shaft 20, and prevents all traction members 51 from being separated from the first rotating shaft 20.

[0084] Please refer to Figure 6 and Figure 7 In order to facilitate pulling the traction member 51 and loosening the end of the traction member 51 away from the first rotating shaft 20, in this embodiment, the traction assembly 50 includes an adjusting member 52, and the adjusting member 52 is threadedly connected to the first connecting member 10. One end of the traction member 51 is wrapped around the adjusting member 52, and the other end of the traction member 51 is wrapped around the first rotating shaft 20. The adjusting member 52 is provided with a limiting groove 521, and the end of the traction member 51 away from the first rotating shaft 20 is located in the limiting groove 521.

[0085] Since the adjusting member 52 is threadedly connected to the first connecting member 10, the traction member 51 can be pulled or the end of the traction member 51 away from the first rotating shaft 20 can be loosened by rotating the adjusting member 52 relative to the first connecting member 10, or the threaded locking torque between the adjusting member 52 and the first connecting member 10 can be used to prevent the camera assembly 30 and the first rotating shaft 20 from rotating together around the axis of the first rotating shaft 20 and along the first direction under the action of the elastic member 40 when there is no need to pull the traction member 51 or loosen the end of the traction member 51 away from the first rotating shaft 20, thereby causing the traction member 51 to pull the adjusting member 52, and the adjusting member 52 can rotate freely relative to the first connecting member 10, so as to fix the end of the traction member 51 away from the first rotating shaft 20. At the same time, the end of the traction member 51 away from the first rotating shaft 20 is located in the limiting groove 521, so that when the traction member 51 is wound around the adjusting member 52, the position of the traction member 51 is limited to prevent the traction member 51 from being separated from the adjusting member 52.

[0086] Optionally, the limiting groove 521 extends along a spiral path. This arrangement makes it easy to accommodate the traction member 51 in the limiting groove 521 and to remove or retract the traction member 51 from the limiting groove 521.

[0087] For example, the adjustment member 52 may be configured as a screw, a bolt or a stud.

[0088] Optionally, in order to prevent the traction member 51 from pulling the adjusting member 52 when there is no need to pull the traction member 51 and loosen one end of the traction member 51 away from the first rotating shaft 20, the adjusting member 52 can rotate freely relative to the first connecting member 10, and the adjusting member 52 is connected to a limiting structure. After the adjusting member 52 rotates relative to the first connecting member 10 by a preset angle, the adjusting member 52 cooperates with the limiting structure to prevent the adjusting member 52 from continuing to rotate relative to the first connecting member 10.

[0089] The limiting structure may include a magnetic adsorption member, which adsorbs the first connecting member 10 and the adjusting member 52 respectively.

[0090] Optionally, the axis of the adjusting member 52 is arranged at an angle to the axis of the first connecting member 10. This arrangement can ensure that when the pulling member 51 does not need to be pulled and the end of the pulling member 51 away from the first rotating shaft 20 is released, the pulling member 51 pulls the adjusting member 52, causing the adjusting member 52 to rotate freely relative to the first connecting member 10, thereby causing the shooting angle of the camera assembly 30 to change.

[0091] Specifically, the length direction of the traction member 51 may be substantially parallel to the axial direction of the first connecting member 10 .

[0092] For example, the angle between the axis of the adjusting member 52 and the axis of the first connecting member 10 is 30 degrees to 60 degrees.

[0093] In this embodiment, the first connecting member 10 includes a main body 101 and a limiting portion 102 connected to each other, the main body 101 is rotatably connected to the first rotating shaft 20, the limiting portion 102 is located at one end of the main body 101 away from the first rotating shaft 20, and the limiting portion 102 is threadedly connected to the adjusting member 52. Such a configuration facilitates the threaded connection of the limiting portion 102 and the adjusting member 52, so that the axis of the adjusting member 52 and the axis of the first connecting member 10 are arranged at an angle.

[0094] The axis of the first connecting member 10 may be the axis of the main body 101. The shape of the limiting portion 102 may be set to be spherical.

[0095] Please refer to Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 In some embodiments, the camera device 100 includes a second rotating shaft 60 coaxially arranged with the first rotating shaft 20, the first rotating shaft 20 and the second rotating shaft 60 are respectively arranged on opposite sides of the camera assembly 30, the camera assembly 30 is fixedly connected to the second rotating shaft 60, and the second rotating shaft 60 is rotatably connected to the first connecting member 10; the elastic member 40 includes a torsion spring, which is sleeved on the second rotating shaft 60, one end of the torsion spring is connected to the camera assembly 30, and the other end of the torsion spring is connected to the first connecting member 10.

[0096] By adopting the above solution, the structure of the elastic member 40 can be made simpler, which is convenient for assembly and the positions of the traction member 51 and the elastic member 40 can be easily arranged.

[0097] Please refer to Fig. 9 and Fig.10 Specifically, the first connecting member 10 is provided with a first abutting portion 103, the camera assembly 30 is provided with a second abutting portion 302, and both ends of the torsion spring abut against the first abutting portion 103 and the second abutting portion 302 respectively.

[0098] For example, when the adjusting member 52 is loosened relative to the first connecting member 10, the traction member 51 moves upward, and at the same time drives the first rotating shaft 20 to rotate, thereby realizing the rotation of the camera assembly 30, and the rotation angle can be 0° to 90°, at which time the torsion spring is squeezed and deformed. When the adjusting member 52 is tightened relative to the first connecting member 10, the traction member 51 moves downward, and under the action of the torsion spring, the camera assembly 30 is reset to a horizontal position.

[0099] Please continue to refer to Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8In some embodiments, the first connecting member 10 is provided with an accommodating channel 11, the camera assembly 30, the elastic member 40 and the traction member 51 are all arranged in the accommodating channel 11, the accommodating channel 11 has an adjustment end (not shown in the figure) and a collection end 111 opposite to each other, the camera assembly 30 is located at the port of the collection end 111, and the traction member 51 extends from the collection end 111 to the adjustment end; the camera device 100 includes a transparent protective cover 70, and the transparent protective cover 70 covers the camera assembly 30.

[0100] Such a configuration can protect the camera assembly 30, prevent the blood tissue inside the human body from contaminating the lens of the camera assembly 30, and will not interfere with the process of the camera assembly 30 collecting images, thereby ensuring the camera effect and extending the service life of the camera assembly 30.

[0101] For example, the material of the transparent protective cover 70 can be silicone or plastic, such as PMMA (PolymethylMethacrylate), PC (Polycarbonate), PP (Polypropylene), PVC (Polyvinyl chloride), ABS (Acrylonitrile Butadiene Styreneplastic) and TPU (Thermoplastic polyurethanes), etc.

[0102] Please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 7 In some embodiments, the camera device 100 includes a second connecting member 80, the second connecting member 80 is provided with a socket 81, the first connecting member 10 is rotatably inserted into the socket 81, and the axis of rotation of the first connecting member 10 relative to the second connecting member 80 is perpendicular to the axis of the first rotating shaft 20.

[0103] By adopting the above scheme, it is possible to pull the traction member 51 or loosen one end of the traction member 51 away from the first rotating shaft 20 by rotating the adjusting member 52 relative to the first connecting member 10, so that the camera assembly 30 rotates around the axis of the first rotating shaft 20, and it is also possible to rotate the first connecting member 10 relative to the second connecting member 80, so that the camera assembly 30 rotates around the axis perpendicular to the axis of the first rotating shaft 20.

[0104] Optionally, the transparent protective cover 70 is disposed on the opening of the insertion hole 81 to prevent blood tissue inside the human body from entering the insertion hole 81 .

[0105] It can be understood that the axis of rotation of the first connecting member 10 relative to the second connecting member 80 is parallel to the Z direction in the figure, and the Z direction can be a vertical direction.

[0106] For example, by rotating the first connecting member 10 relative to the second connecting member 80 , the camera assembly 30 can be rotated in the vertical direction, and the rotation angle is 0° to 360°.

[0107] Optionally, the first connecting member 10 is threadedly connected to the second connecting member 80. This arrangement can prevent the first connecting member 10 from freely rotating relative to the second connecting member 80 when the first connecting member 10 does not need to be rotated relative to the second connecting member 80.

[0108] Please refer to Figure 1 , Figure 2 , Figure 3 and Fig.11 , Fig.11 yes Figure 3 The structure diagram of the universal connection assembly 90 in the camera device 100 is shown.

[0109] In some embodiments, the camera device 100 includes a universal connection assembly 90, which includes a first fixing member 901 and a second fixing member 902, the first fixing member 901 and the second fixing member 902 are connected via a universal structure 903, and the second connecting member 80 is connected to the first fixing member 901.

[0110] By adopting the above scheme, the adjusting member 52 can be rotated relative to the first connecting member 10 to pull the traction member 51 or loosen one end of the traction member 51 away from the first rotating shaft 20, so that the camera assembly 30 rotates around the axis of the first rotating shaft 20. The first connecting member 10 can also be rotated relative to the second connecting member 80 to rotate the camera assembly 30 around the axis perpendicular to the axis of the first rotating shaft 20. At the same time, the universal structure 903 can also be used to realize multi-directional free angle adjustment of the camera assembly 30's shooting range, so as to obtain a clear and good auxiliary field of view.

[0111] The universal structure 903 may be a ball joint, a ball cage universal joint, a cross roller universal joint, a cross shaft universal joint, etc. The universal structure 903 may realize 360° multi-directional free angle adjustment.

[0112] Optionally, the second connecting member 80 can reciprocate relative to the first fixing member 901 along the length direction of the second connecting member 80. In this way, the depth of the camera assembly 30 entering the incision can be limited.

[0113] For example, the first fixing member 901 and the second connecting member 80 can be detachably connected by magnetic adsorption.

[0114] In this embodiment, the first fixing member 901 is provided with a first clamping groove 91, and the second connecting member 80 is inserted into the first clamping groove 91 along its own length direction; the universal connection assembly 90 includes a first locking member 92, and the first locking member 92 passes through the opposite side walls of the first clamping groove 91 along a length direction perpendicular to the second connecting member 80, and the first locking member 92 is threadedly connected to the first fixing member 901.

[0115] By adopting the above solution, the first locking member 92 can be rotated relative to the first fixing member 901 to clamp or release the second connecting member 80 on the opposite side walls of the first clamping groove 91, so that the second connecting member 80 can reciprocate relative to the first fixing member 901 along the length direction of the second connecting member 80. At the same time, the first fixing member 901 and the second connecting member 80 can be assembled and disassembled easily.

[0116] Specifically, the first clamping groove 91 includes a first groove 911 and a second groove 912 that are connected. The first groove 911 is in the shape of a cuboid, and the second groove 912 is in the shape of a cylinder. The second connecting member 80 is arranged in the second groove 912 along its own length direction, and the first locking member 92 passes through the opposite side walls of the first groove 911 along the length direction perpendicular to the second connecting member 80. This arrangement facilitates the clamping of the second connecting member 80 through the first clamping groove 91.

[0117] Optionally, the camera device 100 includes a clamping member 110, the second fixing member 902 is connected to the clamping member 110, and the clamping member 110 is configured as one of a rib retractor, a trocar sleeve, and a mirror grip. This configuration facilitates fixing the entire camera device 100, ensuring that the camera device 100 is fixed in the incision and cannot move, thereby facilitating subsequent image acquisition and ensuring that the camera assembly 30 outputs stable and clear images.

[0118] It should be noted that, in the case where the clamping member 110 is not provided, the camera device 100 can also be directly inserted into the trocar sleeve for use and fixed by the trocar sleeve.

[0119] Among them, when the minimally invasive incision is on the side of the human body, the puncture tube cannot fix the camera device 100. At this time, the camera device 100 can be provided with a clamping member 110, and the clamping member 110 can be a mirror holding arm. One end of the mirror holding arm can be fixed on the operating table 2000, and the other end can clamp the second fixing member 902. The middle universal structure 903 is made of aluminum alloy material, can be bent at any angle, and is stable and not easy to shake, easy to clean, and can also be used in conjunction with the incision lighting device to obtain a clearer and better image inside the incision.

[0120] Optionally, the second fixing member 902 is detachably connected to the clamping member 110. This arrangement facilitates the assembly and disassembly of the second fixing member 902 and the clamping member 110.

[0121] For example, the second fixing member 902 and the clamping member 110 can be detachably connected by means of magnetic adsorption, snap connection, screw connection or bolt connection.

[0122] In this embodiment, the second fixing member 902 is provided with a second clamping groove 94, and part of the clamping member 110 is located in the second clamping groove 94; the universal connection assembly 90 includes a second locking member 93, the second locking member 93 passes through a side wall of the second clamping groove 94, the second locking member 93 is threadedly connected to the second fixing member 902, and one end of the second locking member 93 is abutted against the clamping member 110.

[0123] By adopting the above solution, the second locking member 93 can be rotated relative to the second fixing member 902 so that one end of the second locking member 93 can abut against or move away from the clamping member 110, thereby realizing the assembly and disassembly of the second fixing member 902 and the clamping member 110.
