Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and specifically to a surgical camera device for recording video during surgical procedures. Background Technology

[0002] Surgical video recording devices are one of the important auxiliary devices in modern surgery. Their core function is to capture real-time images of the surgical area (hereinafter referred to as the surgical zone) through a camera, providing clear and detailed records of the surgical process. For example, during dental surgery, doctors will use a camera to record the intraoral dental procedure for later use in surgical review, surgical teaching, and other purposes.

[0003] Because the intraoral surgical area is small, and during dental surgery, the doctor and assistant sit on either side of the patient, it is necessary to install a camera with a high magnification and long focal length at a distance from the patient to avoid obstruction and clearly capture the intraoral surgical area.

[0004] During delicate surgical procedures, the insertion and removal of instruments, the pulling or flushing of tissues can alter the distance between the surgical camera and the target tissue, causing the image to blur momentarily. Since both the surgeon and assistant need direct contact with the surgical area, focusing becomes difficult. To ensure the continuity of the surgical flow, additional personnel are required for real-time focus adjustment, significantly increasing labor costs.

[0005] Therefore, how to provide a surgical camera device with adaptive focal length is a technical problem that urgently needs to be solved by existing technologies. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a surgical camera device that can adaptively adjust the focal length during the operation, which is convenient to operate, saves manpower, and can effectively ensure the continuity of the surgical process.

[0007] The technical solution adopted by this utility model to solve the technical problem is as follows: A surgical camera device, comprising: A surgical light assembly includes a front support plate, a back support plate, a circuit board, and multiple LEDs. The front support plate extends toward the back support plate to form a side support plate. The side support plate is circumferentially disposed on the front support plate. An accommodating space is formed between the front support plate, the back support plate, and the side support plate. The circuit board is fixedly disposed between the front support plate and the back support plate. The multiple LEDs are disposed outside the front support plate. A camera assembly and a binocular navigator are provided. The camera assembly and the binocular navigator are fixedly mounted on the front support plate. Multiple LED beads, the camera assembly, and the binocular navigator are electrically connected to the circuit board. The binocular navigator includes a first camera and a second camera, which are located on both sides of the camera assembly.

[0008] Compared with existing technologies, the advantages of this technical solution are: by providing light through the surgical light assembly, using a binocular navigation system in conjunction with an oral reference plate to locate the surgical area, and then adjusting the focus of the camera based on the surgical area location, the focus can be adaptively adjusted during the operation, which is convenient to operate, saves manpower, and can effectively ensure the continuity of the surgical process.

[0009] Furthermore, it also includes a rotating support member; The rotating support includes a semi-circular support hoop, and a rotating support shaft is fixedly installed at each end of the semi-circular support hoop; The side support plate has two through holes, and the semi-circular support hoop is movably sleeved in the two through holes through two rotating support shafts in a one-to-one correspondence; the surgical lamp assembly rotates around the rotating support shaft under the action of external force.

[0010] The beneficial effects of adopting the above scheme are: the semi-circular support hoop is hinged to the side support plate through the rotating support shafts at both ends, so that the surgical light assembly can drive the camera assembly and the binocular navigator to rotate around the rotating support shaft, which makes it easy to adjust the orientation of the lamp beads, camera assembly and binocular navigator.

[0011] Furthermore, a limiting protrusion is provided on the outer side of the rotating support shaft. When the surgical lamp assembly is rotated around the rotating support shaft under the action of an external force, the limiting protrusion abuts against the side of the front support plate facing the back support plate.

[0012] The beneficial effect of adopting the above solution is that the surgical light assembly is engaged with the front support plate by the limiting protrusion during rotation, which can prevent excessive rotation.

[0013] Furthermore, the circuit board is provided with two PCB limiting recesses. When the circuit board is fixedly disposed between the front support plate and the back support plate, the two PCB limiting recesses and the two sleeve through holes correspond one-to-one, and the PCB limiting recesses abut against the end of the rotating support shaft.

[0014] The beneficial effects of adopting the above solution are: in addition to providing basic electrical connection functions, the circuit board also has a PCB limiting recess, which abuts against the end of the rotating support shaft, making the structural stability of the rotating support shaft better.

[0015] Furthermore, the rotating support shaft is a hollow tubular structure.

[0016] The advantages of adopting the above scheme are: setting the rotating support shaft as a hollow tubular structure, and using the hollow tubular structure to pass through the cable, makes it easier to connect the circuit board to external devices through the cable.

[0017] Furthermore, the camera assembly includes a video data acquisition module and a support base, wherein the video data acquisition module is fixedly mounted on the support base; The first camera has a first support and fixing groove extending outward from its side, and the second camera has a second support and fixing groove extending outward from its side. The first camera and the second camera are respectively fixedly mounted on the support base through the first support and fixing groove and the second support and fixing groove.

[0018] The beneficial effects of adopting the above scheme are: by setting a supporting base, structural support is provided for the video data acquisition module, the first camera and the second camera, and the video data acquisition module, the first camera and the second camera are formed into an overall structure of camera assembly and binocular navigation device, which makes the overall structure of the device better.

[0019] Furthermore, a module limiting groove is formed at the bottom of the video data acquisition module, and the video data acquisition module is fixedly mounted on the support base. The upper edges of the first support fixing groove and the second support fixing groove abut against the module limiting groove. The support base is provided with a base limiting groove, and the lower edges of the first support fixing groove and the second support fixing groove abut against the base limiting groove. Locking bolts are provided in the first support fixing groove and the second support fixing groove, and the first support fixing groove and the second support fixing groove are fixedly mounted to the support base by the locking bolts.

[0020] The beneficial effects of adopting the above solution are: on the one hand, the first support fixing groove and the second support fixing groove abut against the module limiting groove to better fix the first camera and the second camera on the video data acquisition module; on the other hand, they abut against the base limiting groove on the support base and, together with the locking bolt, better fix the first camera and the second camera on the support base.

[0021] Furthermore, the center of the front support plate is recessed downward to form a mounting recess, and a panel limiting vertical groove is formed in the mounting recess; a vertical limiting pin is provided on the side of the support base. The support base is inserted and fixed in the mounting recess on the front support plate, and the vertical limiting pin is sleeved in the panel limiting vertical groove.

[0022] The beneficial effect of adopting the above solution is that by utilizing the cooperation between the vertical limiting pin and the panel limiting vertical groove, the support base can be better fixed on the mounting recess.

[0023] Furthermore, a plurality of handheld controls are provided on the side of the front support plate away from the rear support plate.

[0024] The advantage of adopting the above scheme is that the orientation of the device can be better adjusted by using the handheld control.

[0025] Furthermore, the front support plate and the back support plate are made of aluminum alloy or plastic.

[0026] The advantages of adopting the above scheme are: Aluminum alloy or plastic structures can be used as the front and back support plates as needed. Using aluminum alloy structures as the front and back support plates gives the device advantages such as light weight and high strength; using plastic structures as the front and back support plates gives the device advantages such as low cost and ease of processing.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0035] In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," and "right," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. When a component is referred to as being "fixed to" or "set on" another element, it can be directly on the other component or there may be an intervening component. When a component is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intervening component. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0037] During delicate surgical procedures, the insertion and removal of instruments, tissue traction, or irrigation can all alter the distance between the surgical camera and the target tissue, causing momentary image blurring. Since both the surgeon and assistant need direct contact with the surgical area, focusing is difficult. To ensure the continuity of the surgical flow, additional personnel are required for real-time focus adjustment, significantly increasing labor costs. Therefore, developing a surgical camera with adaptive focus capability to capture real-time images of the surgical area and provide clear, detailed surgical records is a pressing technical challenge that needs to be addressed.

[0038] To address the aforementioned problems, this invention provides a surgical camera device, comprising a surgical light assembly 1, a camera assembly 2, and a binocular navigator. The basic function of the surgical light assembly 1 is to provide illumination for surgical procedures, the camera assembly 2 is used to acquire video image data, and the binocular navigator is used to track the relative position between the camera assembly 2 and the surgical area in real time based on the principle of triangulation.

[0039] like Figure 1 and Figure 2 As shown, the surgical light assembly 1 includes a front support plate 101, a back support plate 102, a circuit board 103, and a plurality of LED beads 104. The front support plate 101 extends toward the back support plate 102 to form a side support plate 105, which is circumferentially disposed on the front support plate 101. This can be understood as the front support plate 101 and the side support plate 105 being an integrally formed structure, with the front support plate 101 being a circular plate structure and the side support plate 105 being a cylindrical sidewall disposed on the front support plate 101. A receiving space is formed between the front support plate 101, the back support plate 102, and the side support plate 105. The circuit board 103 is fixedly disposed between the front support plate 101 and the back support plate 102, and the plurality of LED beads 104 are disposed outside the front support plate 101.

[0040] The camera assembly 2 and the binocular navigator are fixedly mounted on the front support plate 101. Multiple LED beads 104, the camera assembly 2, and the binocular navigator are electrically connected to the circuit board 103. The binocular navigator includes a first camera 3 and a second camera 4, which are positioned on either side of the camera assembly 2. The LED beads 104, the camera assembly 2, and the binocular navigator all face forward.

[0041] Based on the above structure, on the one hand, the surgical light assembly 1 provides light, making it convenient for doctors to maintain good illumination during the operation. On the other hand, the surgical area is located using a binocular navigation system in conjunction with an oral reference plate: an oral reference plate is fixedly set in the patient's oral cavity, and the real-time pose of the oral reference plate is acquired by the first camera 3 and the second camera 4 on the binocular navigation system at the same moment, thereby determining the patient's real-time pose, and then determining the relative position of the surgical area with respect to the camera assembly 2. Based on the relative position of the surgical area and the camera assembly 2, combined with the focal length data of the camera at that relative position, the focal length of the camera can be adjusted. This allows for adaptive focal length adjustment during the operation, which is convenient to operate, saves manpower, and effectively ensures the continuity of the surgical process.

[0042] like Figure 1 and Figure 2 As shown, a surgical camera device includes a surgical light assembly 1, a camera assembly 2, and a binocular navigator, as well as a rotating support 5.

[0043] The rotating support 5 includes a semi-circular support hoop, with a rotating support shaft 501 fixedly installed at each end of the semi-circular support hoop. Correspondingly, two through holes 110 are provided on the side support plate 105. During installation, the semi-circular support hoop is movably fitted into the two through holes 110 through the two rotating support shafts 501 in a one-to-one correspondence; the surgical light assembly 1 rotates around the rotating support shaft 501 under the action of external force. When it is necessary to adjust the orientation of the lamp bead 104, the camera assembly 2, and the binocular navigator, an external force can be applied to drive the surgical light assembly 1 to rotate around the rotating support shaft 501 within a certain angle range until the lamp bead 104, the camera assembly 2, and the binocular navigator reach the target orientation.

[0044] Based on the above structure, the semi-circular support hoop is hinged to the side support plate 105 through the rotating support shafts 501 at both ends, so that the surgical light assembly 1 can drive the camera assembly 2 and the binocular navigator to rotate around the rotating support shaft 501, which makes it easy to adjust the orientation of the lamp bead 104, the camera assembly 2 and the binocular navigator.

[0045] like Figure 3 and Figure 4 As shown, preferably, a limiting protrusion 502 is provided on the outer side of the rotating support shaft 501. When the surgical lamp assembly 1 is rotated around the rotating support shaft 501 under the action of an external force, the limiting protrusion 502 abuts against the side of the front support plate 101 facing the back support plate 102.

[0046] When the surgical light assembly 1 rotates around the rotating support shaft 501 under the action of an external force, the limiting protrusion 502 also moves with the rotating support shaft 501. During the rotation of the rotating support shaft 501, when it rotates to the left to its limit, the limiting protrusion 502 will abut against the front support plate 101; when it rotates to the right to its limit, the limiting protrusion 502 will also abut against the front support plate 101. Therefore, the rotation angle of the rotating support shaft 501 is limited. Based on this structure, the surgical light assembly 1 is engaged with the front support plate 101 by the limiting protrusion 502 during rotation, which can prevent excessive rotation.

[0047] like Figure 3 and Figure 4As shown, preferably, the circuit board 103 is provided with two PCB limiting recesses 106. When the circuit board 103 is fixedly disposed between the front support plate 101 and the back support plate 102, the two PCB limiting recesses 106 and the two sleeve through holes 110 correspond one-to-one, and the PCB limiting recesses 106 abut against the end of the rotating support shaft 501.

[0048] When the rotating support shaft 501 is inserted into the sleeve through hole 110, the limiting protrusion 502 is located on one side of the sleeve through hole 110, and the end of the rotating support member 5 is located on the other side of the sleeve through hole 110. There is a certain gap between the limiting protrusion 502 and the end of the rotating support member 5. When subjected to external force, the rotating support shaft 501 may move in and out of the sleeve through hole 110, which has a certain impact on the overall structural stability of the device.

[0049] Based on the above structure, the PCB limiting recess 106 on the circuit board 103 abuts against the end of the rotating support shaft 501. In addition to providing basic electrical connection functions, the circuit board 103 also provides the PCB limiting recess 106, which abuts against the end of the rotating support shaft 501, thereby improving the structural stability of the rotating support shaft 501.

[0050] Preferably, the rotating support shaft 501 is a hollow tubular structure, and the rotating support shaft 501 utilizes the hollow tubular structure for wiring. By setting the rotating support shaft 501 as a hollow tubular structure and using the hollow tubular structure to pass through the cables, it is convenient to connect the circuit board 103 to external devices via cables.

[0051] like Figure 5 As shown, preferably, the camera assembly 2 includes a video data acquisition module 201 and a support base 202, with the video data acquisition module 201 fixedly mounted on the support base 202. A first support mounting groove 301 extends outward from the side of the first camera 3, and a second support mounting groove 401 extends outward from the side of the second camera 4. The first camera 3 and the second camera 4 are respectively fixedly mounted on the support base 202 via the first support mounting groove 301 and the second support mounting groove 401.

[0052] In the above structure, the supporting base 202 serves to fix the video data acquisition module 201, the first camera 3, and the second camera 4. The video data acquisition module 201 is placed above the supporting base 202, and the first camera 3 and the second camera 4 are respectively placed on both sides of the supporting base 202. By setting the supporting base 202, structural support is provided for the video data acquisition module 201, the first camera 3, and the second camera 4, forming an overall structure of the camera assembly 2 and the binocular navigator, thus improving the overall structural integrity of the device.

[0053] like Figure 5 As shown, preferably, a module limiting groove 203 is formed at the bottom of the video data acquisition module 201. The video data acquisition module 201 is fixedly mounted on the support base 202, and the upper edges of the first support fixing groove 301 and the second support fixing groove 401 abut against the module limiting groove 203. By embedding the first support fixing groove 301 and the second support fixing groove 401 into the module limiting groove 203, the structural connection between the first camera 3, the second camera 4, and the video data acquisition module 201 is made more secure.

[0054] The support base 202 is provided with a base limiting groove 204, and the lower edges of the first support fixing groove 301 and the second support fixing groove 401 abut against the base limiting groove 204; two locking bolts 6 are provided in the first support fixing groove 301 and the second support fixing groove 401, and the first support fixing groove 301 and the second support fixing groove 401 are fixedly mounted on the support base 202 by the locking bolts 6.

[0056] Based on the above structure, the first support fixing groove 301 and the second support fixing groove 401 abut against the module limiting groove 203 to better fix the first camera 3 and the second camera 4 on the video data acquisition module 201, and abut against the base limiting groove 204 on the support base 202, and together with the locking bolt 6, to better fix the first camera 3 and the second camera 4 on the support base 202.

[0057] like Figure 6As shown, preferably, the center of the front support plate 101 is recessed downward to form a mounting recess 107, and a panel limiting vertical groove 108 is formed in the mounting recess 107; a vertical limiting pin 205 is provided on the side of the support base 202; the support base 202 is inserted and fixed in the mounting recess 107 on the front support plate 101, and the vertical limiting pin 205 is sleeved in the panel limiting vertical groove 108.

[0058] The support base 202 is fixedly installed on the surgical lamp assembly 1 via the front support plate 101. The vertical limiting pin 205 and the panel limiting vertical groove 108 cooperate with each other to better fix the support base 202 in the mounting recess 107, further ensuring the structural stability of the device.

[0059] like Figure 1 and Figure 2 As shown, preferably, a plurality of handheld control elements 109 are provided on the side of the front support plate 101 away from the rear support plate 102. The orientation of the device can be better adjusted by holding the handheld control element 109. During operation, the overall orientation of the device can be adjusted simply by holding the handheld control element 109.

[0060] Preferably, the front support plate 101 and the back support plate 102 are made of aluminum alloy or plastic. The front support plate 101 and the back support plate 102 are made of aluminum alloy or plastic as needed. Using an aluminum alloy structure for the front support plate 101 and the back support plate 102 gives the device advantages such as light weight and high strength; using a plastic structure for the front support plate 101 and the back support plate 102 gives the device advantages such as low cost and ease of processing.
