Description

Technical Field

[0001] This utility model relates to the field of surgical field camera technology, specifically a fixed bracket with a flexibly adjustable shooting angle and a surgical field camera. Background Technology

[0002] The surgical field is a medical term that refers to the area of ​​vision during surgery. Surgical field cameras are used to record the entire surgical process in real time so that the footage can be made into DVDs for storage, to meet the needs of patients' families who want to watch the surgical procedure, or for research, teaching, and case archiving.

[0003] Traditional surgical field cameras are directly fixed to the wall or a mounting bracket, which limits the range of adjustable shooting angles. During surgery, they are easily obstructed by medical staff, making it difficult to adjust them to fully cover the surgical field. This will not meet the needs of teaching, recording, and broadcasting the surgical process. Summary of the Invention

[0004] A primary objective of this application is to provide a mounting bracket that improves the range of adjustment for the shooting angle of a surgical field camera.

[0005] To achieve the above-mentioned application objectives, this application adopts the following technical solution: According to one aspect of this application, a mounting bracket is provided for fixing a camera, characterized in that the mounting bracket includes: a mounting cylinder, a first mounting arm, a second mounting arm, a first driving member, a second driving member, and a third driving member; the first driving member is disposed inside the mounting cylinder, a first driving shaft disposed on the first driving member extends and is fixed to the camera, and the extension direction of the first driving shaft coincides with the extension direction of the central axis of the camera; one end of the second driving member is connected to one end of the first mounting arm, and a second driving shaft disposed on the other end of the second driving member is connected to the mounting cylinder, the mounting cylinder being rotatable relative to the first mounting arm along the second driving shaft; one end of the third driving member is connected to the end of the first mounting arm away from the second driving member, and the other end of the third driving member is connected to the second mounting arm, the first mounting arm being rotatable relative to the second mounting arm along the third driving shaft disposed on the third driving member; the extension directions of any two of the first driving shaft, the second driving shaft, and the third driving shaft are perpendicular to each other.

[0006] According to another aspect of this application, a surgical field camera is provided, including the aforementioned mounting bracket, wherein the camera is mounted and fixed to the mounting bracket.

[0007] The fixation frame and surgical field camera provided in this application enable the camera to be adjustable in three dimensions via mutually perpendicular first, second, and third drive axes. This allows for more flexible adjustment of the camera's shooting angle, allowing for more precise aiming of the camera at the surgical site during surgery. Furthermore, the first, second, and third drive components can automatically adjust the camera's shooting angle when powered on, effectively avoiding secondary contamination that may result from manual touching of the mounting frame.

[0008] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

However, these example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed descriptions will be omitted. The technical solutions of the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0015] This application provides a fixing bracket, such as... Figure 1 and Figure 2 As shown, the mounting bracket 100 is used to fix a camera (not shown). The mounting bracket 100 includes: a mounting cylinder 10, a first mounting arm 30, a second mounting arm 50, a first driving member (not shown), a second driving member (not shown), and a third driving member (not shown). The first driving member is disposed within the mounting 10, and a first driving shaft (not shown) on the first driving member extends and is fixed to the camera, with the extension direction of the first driving shaft coinciding with the extension direction of the camera's central axis. One end of the second driving member is connected to the mounting cylinder 10, and the other end is connected to one end of the first mounting arm 30. The mounting cylinder 10 can rotate relative to the first mounting arm along the second driving shaft on the second driving member. One end of the third driving member is connected to the end of the first mounting arm 30 away from the second driving member, and the other end of the third driving member is connected to the second mounting arm 50. The first mounting arm 30 can rotate relative to the second mounting arm 50 along the third driving shaft on the third driving member (please also refer to...). Figure 1 and Figure 4 Of the first drive shaft, the second drive shaft, and the third drive shaft, the extension directions of any two are perpendicular to each other.

[0016] The surgical field camera provided in this application allows for adjustable angles in three dimensions via mutually perpendicular first, second, and third drive axes. This makes the camera's shooting angle adjustment more flexible, enabling more precise aiming at the surgical site during surgery. Furthermore, the first, second, and third drive components can automatically adjust the camera's shooting angle when powered on, effectively avoiding secondary contamination that may result from manual contact with the mounting bracket.

[0017] In one embodiment, the mounting bracket further includes a fourth drive member (not shown) and a fixing member 70. One end of the fourth drive member is connected to the end of the second mounting arm 50 away from the third drive member, and the other end of the fourth drive member is rotatably connected to the fixing member 70. The fixing member 70 is mounted on a wall or mounting bracket, and the extension direction of the fourth drive shaft provided on the fourth drive member is perpendicular to the extension direction of the third drive shaft.

[0018] With the aforementioned fourth driving component and fixing component 70, the mounting bracket of this application can be installed on the wall at the top of the operating room or on the mounting bracket inside the operating room via the fixing component 70; and the fourth driving shaft is perpendicular to the horizontal plane, so that the second mounting arm 50 can also rotate around the fourth driving shaft, adjusting the overall deflection angle in the horizontal direction, making it easier for the mounting bracket to more accurately adjust and align the camera with the surgical site.

[0019] Further, referring to Figure 3, the second mounting arm 50 includes a main body 51 and a connecting part 53. The side projection of the main body 51 is inverted L-shaped. A mounting groove 511 is formed at the top of one end of the main body 51. Specifically, the surface of the wider end of the side projection of the main body 51 is recessed downward to form the mounting groove 511, for mounting the fourth driving member within the mounting groove 511. The connecting part 53 is vertically connected to the side of the other end of the main body 51. Specifically, the connecting part 53 is vertically connected to the other end of the main body 51 (i.e., the end with the narrower side projection), and the end surface of the connecting part 53 is recessed downward to form a fixing groove 531, for fixing the third driving member. The extending direction of the mounting groove 511 is perpendicular to the extending direction of the fixing groove 531, such that the extending directions of the third driving shaft on the third driving member and the fourth driving shaft on the fourth driving member are perpendicular to each other. The mutually perpendicular third and fourth drive axes enable the camera on the mounting bracket to adjust its angle and degree along two mutually perpendicular dimensions.

[0020] Specifically, the main body 51 is an irregularly shaped, hollow column. From the end forming the mounting groove 511 towards the connecting adapter 53, the periphery of the sidewall of the main body 51 bulges outwards, correspondingly increasing the internal space of the main body 51 and providing more space for mounting drive components and wiring. The end of the main body 51 opposite to the mounting groove 511 extends away from the mounting groove 511 on one side and avoids the adapter 53 on the other side, allowing the adapter 53 to be vertically connected from the end away from the mounting groove 511 to the extended portion of the main body 51. Furthermore, the first mounting arm 30 connected to the adapter 53 has sufficient space to rotate relative to the adapter 53.

[0021] Furthermore, the adapter 53 is a hollow cylinder, and its entirety is perpendicularly connected to one end of the main body 51. The inner cavity of the adapter 53 is connected to the inner cavity of the main body 51, allowing the conductive wires, control wires, and other components of the mounting bracket to be housed within the bracket, preventing exposure and ensuring optimal light or image acquisition. In other embodiments, the main body 51 can be a hollow cylinder, and the adapter 53 can be a hollow cylinder with an inverted L-shaped side.

[0022] It is understood that the main body 51 and the connecting part 53 are not limited to the above-described shapes, as long as the fourth driving member mounted on the main body 51 and the third driving member mounted on the connecting part 53 have perpendicular extension directions, and the inner cavity of the main body 51 is connected to the inner cavity of the connecting part 53.

[0023] Referring to Figures 1 and 3, in one embodiment, the first mounting arm 30 includes a hinge portion 31 and a support portion 33 connected thereto. The hinge portion 31 is connected to the adapter portion 53 via a third drive member, allowing the first mounting arm 30 to rotate relative to the second mounting arm 50 along the third drive member between the hinge portion 31 and the adapter portion 53. The support portion 33 is connected to the mounting cylinder 10 via a second drive member, and the plane of the support portion 33 is perpendicular to the plane of the hinge portion 31, such that the extension directions of the third drive shaft on the third drive member and the second drive shaft on the second drive member are perpendicular to each other. The perpendicular third drive shaft and the second drive shaft also enable the camera on the mounting bracket to adjust its angle in conjunction along two mutually perpendicular dimensions.

[0024] Specifically, the outer contour of one end of the hinge portion 31 is roughly disc-shaped, facilitating rotation relative to the transition portion 53; the outer contour of the end of the bearing portion 33 away from the hinge portion 31 is also roughly disc-shaped, providing sufficient installation space for the second driving member. The opposing ends of both the hinge portion 31 and the bearing portion 33 are recessed and extended to form a transition portion 35. The transition portion 35 connects the hinge portion 31 and the bearing portion 33, while also providing sufficient rotation space for the mounting cylinder 10 mounted on the bearing portion 33.

[0025] The first mounting arm 30 of this application, through a special structural design, provides sufficient rotation space for both the second mounting arm 50 and the mounting cylinder 10 connected to the first mounting arm 30. This makes the structure of the mounting bracket of the present invention more compact, occupies less area, and effectively reduces the obstruction of light by the mounting bracket. Furthermore, this special structural design also allows the camera to adjust the deflection angle in conjunction with two perpendicular dimensions, making the camera angle adjustment more convenient and precise.

[0026] In one embodiment, one end of the mounting cylinder 10 is open (not shown in the figure), and the first driving member is fixed at the opposite end. The camera is fixed by the first driving shaft on the first driving member, so that the camera can be exposed through the opening for framing, and the camera can be rotated along the first driving shaft to adjust the shooting angle.

[0027] In this embodiment, after the camera is fixed inside the mounting cylinder 10 and connected to the first driving member, the rotation of the first driving shaft can drive the camera to rotate along the first driving shaft to adjust the shooting angle. Simultaneously, the mounting cylinder 10 as a whole can rotate relative to the support portion 33 along the second driving shaft to adjust the camera's deflection angle. Simultaneously, the first mounting arm 30 can rotate along the third driving shaft to adjust the camera's height. Simultaneously, the second mounting arm can rotate along the fourth driving member to adjust the overall deflection angle of the mounting bracket, thereby adjusting the camera's deflection angle. Further, the camera can rotate 0-180° relative to the mounting cylinder 10 along the first driving shaft; and / or, the mounting cylinder 10 can rotate 0-180° or 0-90° relative to the first mounting arm 30 along the second driving shaft; and / or, the second mounting arm 50 can rotate 0-350° relative to the fixing member 70 along the fourth driving shaft.

[0028] As can be seen, the mounting bracket of this application, through the linkage adjustment of the above four driving components, can ensure that the camera can be adjusted to meet the shooting requirements of any angle.

[0029] In one embodiment, the overlapping area of ​​the projections of the adapter 53, the main body 51, and the support 33 in the height direction is maximized to make the fixture 100 structure compact and avoid blocking light, especially light in the height direction. In another embodiment, particularly in non-top lighting applications, the overlapping area of ​​the projections of the adapter 53, the main body 51, and the support 33 in the height direction may not overlap.

[0030] Furthermore, the mounting bracket also includes a control component 90. The first, second, third, and fourth driving components are all motors. The control component 90 is electrically connected to the first, second, third, and fourth driving components to control the four motors to adjust the shooting angle of the camera through signals emitted by the control component 90.

[0031] In one embodiment, the control component 90 is disposed on one of the following: mounting cylinder 10, first mounting arm 30, second mounting arm 50, or fixing bracket 70. In one embodiment, the control component 90 is preferably disposed on the outer wall of the mounting cylinder 10.

[0032] This application also provides a surgical field camera, which includes the aforementioned mounting bracket and camera. The camera is fixed in the mounting cylinder 10 and can be adjusted to different heights, deflection angles, lens rotation angles, and other parameters under the adjustment of the first driving member, the second driving member, the third driving member, and the fourth driving member to meet different shooting needs.

[0033] The fixation frame and surgical field camera provided in this application enable the camera to be adjustable in three dimensions via mutually perpendicular first, second, and third drive axes. This allows for more flexible adjustment of the camera's shooting angle, allowing for more precise aiming of the camera at the surgical site during surgery. Furthermore, the first, second, and third drive components can automatically adjust the camera's shooting angle when powered on, effectively avoiding secondary contamination that may result from manual touching of the mounting frame.
