Description

Technical Field

[0001] This utility model relates to the technical field of surgical field camera auxiliary products, specifically a horizontal translation mechanism for a surgical field camera. Background Technology

[0002] Surgical field cameras are image acquisition devices specifically designed for medical surgical scenarios, primarily serving surgical teaching, remote consultations, and live streaming / recording. Traditional surgical field cameras use a boom for vertical lifting or rotation adjustment, with a rotation angle reaching 360°. However, the center of axial rotation is fixed, resulting in a fixed field of view at a single angle. When the surgical area expands (e.g., in multi-incision surgeries) or when switching observation angles is necessary, the entire boom position must be repeatedly adjusted, which is time-consuming and can easily disrupt the surgical procedure. Furthermore, in complex surgeries, the observer may need to observe surgical details from different angles. This is achieved through multiple devices or manual adjustments. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a horizontal translation mechanism for surgical field cameras, which solves the problem of limited observation angles for surgical field cameras.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a horizontal translation mechanism for a surgical field camera, comprising a boom for fixing the camera, wherein the boom includes a first bracket, a second bracket, a mounting rail, and a fixing component, wherein...

[0005] The mounting guide rail is fixed at intervals to the fixing component;

[0006] One end of the first bracket is connected to the fixing member, and the other end extends circumferentially with the fixing member as the fixing point and is slidably connected to the mounting guide rail;

[0007] One end of the second bracket is connected to the end of the first bracket near the mounting rail, and the other end is used to fix the camera. The second bracket can rotate relative to the first bracket along a vertical plane.

[0008] Preferably, the first bracket includes a horizontal arm and an end head. The horizontal arm is telescopically adjustable in length, with one end fixed to the fixing member and the other end mounted with the end head, which is slidably connected to the mounting guide rail.

[0009] Preferably, the horizontal arm includes a docking shaft connected to the fixing member and an intermediate sleeve, a left sleeve, and a right sleeve that are slidably sleeved together in sequence, wherein the right sleeve is connected to the docking shaft and the left sleeve is connected to the end.

[0010] Preferably, the first bracket further includes a connector connected to the lower end of the end;

[0011] The second bracket includes an extension arm, two bushings, and a vertical rod disposed at the end of the extension arm;

[0012] One end of the extension arm is connected to the connector via a bushing and can rotate relative to the end along a vertical plane;

[0013] The other end of the extension arm is connected to the plumb line via a bushing, and the camera is connected to the plumb line via the plumb line.

[0014] Preferably, the mounting guide rail includes two identical mounting plates that are symmetrically arranged on the left and right. The mounting plates have a first chamber and a second chamber. A screw is installed in the first chamber, and a buckle plate that is fastened to the end is installed in the second chamber. One end of the buckle plate is connected to a drive plate, and the drive plate extends into the first chamber and is threadedly connected to the screw.

[0015] Preferably, the first chamber and the second chamber are connected, with the first chamber located at the end of the second chamber away from the end. The end includes a top plate and a straight rod perpendicular to the top plate and coaxially connected. The diameter of the straight rod is smaller than the diameter of the top plate, and the buckle plate has an L-shaped cross-section to adapt to its connection with the end and the straight rod.

[0016] Preferably, the mounting plate and the fixing component are both installed on the preset wall by bolts.

[0017] Compared with the prior art, this utility model provides a horizontal translation mechanism for a surgical field camera, which has the following advantages:

[0018] The technical solution disclosed in this utility model differs from the existing technology of adjusting the surgical field camera using a single axial rotation center. Instead, the horizontal translation mechanism is integrated on the boom, which allows the axial rotation center to change position, thereby generating a surround view with multiple interconnected fields of view. This results in a situation that differs from the single angle and single viewpoint in the existing technology, and produces a small-angle conversion of the surgical field.

[0027] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Figures 1-6 As an embodiment of this utility model, the specific problem addressed by this specific embodiment is as follows: Traditional surgical field cameras use a boom 2 for vertical lifting or rotation adjustment, and its rotation angle can reach 360°. However, the center of its axial rotation is fixed, so the field of view generated at a single angle is also fixed. However, the position of the lesion is not uniform, which may result in the lesion not being visible at this angle. The position of the doctor's platform is fixed, and when operating the surgical field camera, it is necessary to avoid the doctor's position to prevent obstruction. Therefore, when the surgical area is expanded (such as multi-incision surgery) or the observation angle needs to be changed, the position of the entire boom 2 needs to be repeatedly adjusted, or it can be achieved through multiple devices or manual adjustment.

[0030] Based on the above, this application proposes a scheme for a horizontal translation mechanism for a surgical field camera, which includes a boom 2, a camera 1 fixed in the boom 2, the camera 1 being model SY-HD900, and the boom 2 driving the camera 1 to adjust the shooting angle.

[0031] The boom 2 includes a first support 3, a second support 4, a mounting rail 5, and a fixing member 6. The first support 3 includes a horizontal arm 31, which is telescopically adjustable in length. One end of the horizontal arm 31 is fixed to the fixing member 6, and an end cap 32 is installed at the end of the horizontal arm 31. One end of the end cap 32 is internally connected to the mounting rail 5, and the lower end of the end cap 32 is connected to a connector 33. The second support 4 includes an extension arm 41 and bushings 42 located at the left and right ends of the extension arm 41. The left bushing 42 is connected to the connector 33 through the connector 33, and the right bushing 42 is connected to the camera 1 through a plumb line 43. The first support 3 extends circumferentially from the fixed point (i.e., at the fixing member 6), indirectly driving the camera 1 to rotate 360°. The second support 4 is rotatably connected to the end of the first support 3 and extends longitudinally. The end cap 32 of the first support 3 is mainly the center of axial rotation of the camera 1, so that the camera 1 rotates around the end cap 32 under the drive of the second support 4. The second support 4 then drives the camera 1 to move closer to or further away from the lesion.

[0032] The mounting guide rail 5 includes two identical mounting plates 51 that are symmetrical on the left and right. The mounting plates 51 and the fixing parts 6 are all installed on the preset wall by bolts. The mounting plates 51 have a first chamber 52 and a second chamber 53. The first chamber 52 and the second chamber 53 are connected. The first chamber 52 is located at the end of the second chamber 53 away from the end 32. The end 32 includes a top plate and a straight rod that is perpendicular to the top plate and coaxially connected. The diameter of the straight rod is smaller than the diameter of the top plate. The buckle plate 55 has an L-shaped cross section to adapt to its connection with the end 32 and the straight rod. The screw 54 is installed in the first chamber 52, and the second chamber 53 is equipped with a buckle plate 55 that is fastened to the end 32. One end of the buckle plate 55 is connected to the drive plate 56. The thickness of the drive plate 56 is less than the thickness of the buckle plate 55. The drive plate 56 extends into the first chamber 52 and is threadedly connected to the screw 54. The screw 54 is driven to rotate by a drive motor placed in the first chamber 52. Under its rotation, it drives the movement of the end 32 as a whole. Based on the connection method of rotating the docking shaft 34, there will be no movement interference or obstruction.

[0033] The horizontal arm 31 consists of three sections: a right sleeve 311 connected to the docking shaft 34, a middle sleeve 313 that slides and fits into each other in sequence, and a left sleeve 312 that is the same as the right sleeve 311. The left sleeve 312 is connected to the end 32 through a sleeve. When it is necessary to extend the connection distance, the middle sleeve 313 is pulled out from between the left sleeve 312 and the right sleeve 311 to increase the length. The horizontal arm 31 is connected to the fixing member 6 through the docking shaft 34. The docking shaft 34 is rotatably connected to the fixing member 6. In this embodiment, the rotatable connection can be achieved by a conventional connection method such as rolling bearing connection or clearance connection. The fixed connection is achieved by existing conventional methods such as interference connection or welding. The horizontal arm 31 is fixedly connected to the end 32 through the sleeve. When the screw 54 drives the buckle plate 55 to move, the end 32 changes position, and the horizontal arm 31 is forced to extend, causing the docking shaft 34 to follow. Based on the setting of the flat horizontal support, the horizontal arm 31 is extended to satisfy the end 32 to move position based on the drive of the screw 54. At this time, the position of the first support 3 changes, and the rotation center of the second support 4 drives the camera 1 to change. The position and field of view of the camera 1 at a certain angle will be different, increasing the field of view angle.

[0034] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
