Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a detachable three-dimensional external viewing mirror. Background Technology

[0002] In modern surgical procedures, especially in the field of minimally invasive surgery, there are extremely high requirements for the clarity, stereoscopic effect, and operational flexibility of the surgical field. Traditional two-dimensional exoscopes lack stereoscopic vision, making it difficult to meet the surgeon's needs for precise positioning and depth perception of the surgical site. While three-dimensional exoscopes can significantly improve the accuracy and safety of surgery, existing three-dimensional exoscopes and endoscope cameras are mostly integrated designs that cannot be separated. They also have complex structures, are difficult to maintain, and lack sufficient flexibility to adapt to changing surgical needs.

[0003] Therefore, in view of the shortcomings of existing technology, it is necessary to design a detachable three-dimensional external mirror to solve the above problems.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and facilitating the understanding of those skilled in the art. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background section of this utility model. Utility Model Content

[0020] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0021] This invention employs a detachable connection between the vertical and horizontal endoscope tubes, facilitating maintenance and component replacement. Two vertical and two horizontal optical paths are precisely aligned via a reflective prism assembly, forming two independent sampling optical paths that provide a true three-dimensional field of view. Simultaneously, the sampling optical paths can be rotated, enhancing the flexibility of surgical operations.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a detachable three-dimensional external mirror, including a vertical mirror tube 1 and a horizontal mirror tube 2 that are detachably connected in sequence. The main components of this utility model will be described in detail below:

[0035] The vertical lens tube 1 is equipped with: two independent vertical optical paths 11, each connected to a sampling lens 13 at its front end, and an optical zoom component 14 at the sampling lens 13; and a vertical optical fiber 12, with an illumination converging lens 15 at its front end.

[0036] The horizontal lens tube 2 is equipped with: two independent horizontal optical paths 21, each with an eyepiece connected to its rear end, and a focusing device 23 at the eyepiece; a horizontal optical fiber 22, the front end of which is inserted and connected to the rear end of the vertical optical fiber 12, and the rear end of which is connected to the beam guide interface 24. The light source is input through the beam guide interface 24, and the light intensity emitted by the illumination converging lens 15 is adjusted by controlling the light source intensity.

[0037] The rear ends of the two vertical optical paths 11 and the front ends of the two horizontal optical paths 21 are connected and connected after being turned 90° by the reflective prism assembly 3, forming two independent sampling optical paths.

[0038] In some embodiments, such as Figure 1 As shown, a beam splitter 25 is provided at the eyepiece, and the two eyes can observe the dual-path image distributed by the beam splitter 25 through the eyepiece to form a three-dimensional stereoscopic vision.

[0039] In some embodiments, such as Figure 1 and Figure 2 As shown, the optical zoom component 14 includes a zoom lens group 141 and a focal length control component 142 that drives the zoom lens group 141 to move. The focal length of the zoom lens group 141 is changed by the focal length control component 142 to achieve zooming of the sampling field of view.

[0040] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the focusing device 23 includes:

[0041] Focusing mount 231 fixed to the horizontal lens tube 2;

[0042] The positioning sleeve 232 is coaxially mounted on the focusing seat 231, and its side wall has a through linear guide groove 232a along the axial direction.

[0043] The lens barrel 233 is coaxially disposed in the positioning sleeve 232, and its outer wall is provided with a radially extending lever 233a, which passes through the linear guide groove 232a to its outer side.

[0044] A focusing sleeve 234 is coaxially disposed on the outer periphery of the positioning sleeve 232, and its inner wall is provided with a spiral guide groove 234a that slides with the lever 233a. Rotating the focusing sleeve 234 causes the spiral guide groove 234a to push the lever 233a to move along the linear guide groove 232a, thereby driving the lens barrel 233 to axially displace and achieve stepless adjustment of the focal length.

[0045] In some embodiments, such as Figure 1 As shown, the illumination angle of the illumination focusing lens 15 can be adjusted independently to change the illumination range.

[0046] In some embodiments, such as Figure 1 As shown, the beam guide interface 24 adopts an international standard interface to ensure compatibility and interchangeability with various light sources and beam guides, facilitating equipment maintenance and upgrades.

[0047] In some embodiments, such as Figure 1 As shown, the eyepiece is equipped with a connector for connecting an endoscope camera, which is suitable for deep tissue observation.

[0048] In some embodiments, such as Figure 1 As shown, the eyepiece is connected to the image processor, which transmits the image to the image processor to synthesize 3D video.

[0049] During laparoscopic surgery, doctors can use an external endoscope alone to observe the surgical area. The stereoscopic field of view provided by dual optical paths significantly improves the identification of tissue layers and reduces the risk of misoperation. Alternatively, it can be connected to an endoscope camera for collaborative observation of deep tissues, further reducing the risk of misoperation.

[0050] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
