Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a sub-thrown electronic endoscope with adjustable angle. Background Technology

[0002] In the diagnosis and treatment of thoracic and abdominal diseases, endoscopy has become an indispensable and important tool due to its minimally invasive and visualization advantages. Currently, thoracic and abdominal endoscopes mainly include two categories: traditional optical endoscopes and electronic endoscopes. Traditional optical endoscopes use optical fibers for image transmission, while electronic endoscopes use miniature image sensors. Existing common types are reusable electronic endoscopes using fiber optic illumination, and newer semi-disposable electronic endoscopes with built-in LED lighting, whose endoscope body is detachable and replaceable, as described in patent publication number CN116999008A.

[0003] Semi-disposable electronic endoscopes connect to the handle via a Type-C or USB interface and are typically disposable, effectively reducing the risk of cross-infection and simplifying equipment reprocessing. However, compared to traditional optical endoscopes, this type of endoscope presents a significant operational obstacle: rotation. During surgery, surgeons need to observe numerous areas, some located at the base of organs or on the abdominal wall, requiring the lens (usually a 30-degree lens) to be rotated for observation. Optical endoscopes, connected to an adapter, can rotate 360 ​​degrees, allowing for viewing at different angles simply by rotating the endoscope. However, because semi-disposable electronic endoscopes connect via Type-C or USB, they cannot be directly rotated; the wrist holding the handle must be rotated to adjust the viewing angle. But the human wrist has limited rotation range, and maintaining a large angle of rotation for extended periods can easily cause soreness and affect surgical procedures.

[0004] Therefore, it is necessary to improve existing technologies. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an angle-adjustable sub-thrown electronic endoscope, thereby solving the problem that the lens angle of existing sub-thrown electronic endoscopes is not easy to adjust.

[0006] The technical solution adopted in this utility model is: an angle-adjustable sub-jet electronic endoscope, including a lens, a tube, a connector and an angle adjustment assembly;

[0007] The lens includes a housing, a glass window, an illumination module, a camera, and a video module connected to the camera; the housing has a front opening, the glass window is fixed to the front opening surface of the housing, the illumination module, the camera, and the video module are located inside the housing, and the illumination module and the video module are each equipped with cables;

[0008] The housing is rotatably connected to the front end of the lens tube, with the glass window facing outwards. The connector is installed at the rear end of the lens tube. The cables of the illumination module and the camera module both pass through the rear end of the housing and extend along the axial direction of the lens tube to connect with the connector.

[0009] The angle adjustment assembly includes a transmission rod and a drive rod; the transmission rod is disposed inside the lens tube, the front end of the transmission rod is hinged to the rear end of the lens housing, and the rear end of the transmission rod is connected to the inner end of the drive rod.

[0010] According to the above scheme, the angle adjustment component also includes a slot and a sliding button; the slot is formed on the wall of the lens tube, the sliding button is slidably connected to the slot, and the inner side of the sliding button is fixedly connected to the outer end of the drive rod.

[0011] According to the above scheme, the drive rod is arranged perpendicular to the axial direction of the mirror tube.

[0012] According to the above scheme, a self-lubricating pad is provided on the inner circumferential surface of the front end of the endoscope tube, and the housing is connected to the endoscope tube through the self-lubricating pad.

[0013] According to the above scheme, the self-lubricating pad is made of silicone or rubber material.

[0014] According to the above scheme, the self-lubricating pad is annular and located on the inner wall of the front end of the lens tube, wrapping the outer side of the shell.

[0015] According to the above scheme, the lighting module is connected to the connector via a corresponding lighting cable, and the camera module is connected to the connector via a corresponding image cable.

[0016] According to the above scheme, both the drive rod and the transmission rod are made of plastic.

[0017] According to the above scheme, the lens housing is hemispherical.

[0018] According to the above scheme, the inner end of the drive rod is connected to the transmission rod through the first fixing ring; the front end of the transmission rod is connected to the housing through the second fixing ring.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This invention utilizes a transmission rod and a drive rod to form an angle adjustment component. Medical personnel can quickly adjust the lens angle simply by pushing and pulling the drive rod. This operation method greatly reduces the wrist rotation during surgery, reducing the soreness caused by maintaining a large angle of rotation for extended periods. It allows doctors to more easily and accurately observe target areas located at the bottom of organs, the abdominal wall, and other special locations, significantly improving the smoothness and precision of surgical procedures and providing a strong guarantee for the successful execution of surgery. This solves the problem of inconvenient lens angle adjustment in existing disposable electronic endoscopes. 2. This invention achieves angle adjustment through basic components such as the transmission rod and drive rod, eliminating the need for complex mechanical structures or precision parts. This reduces manufacturing difficulty and material and processing costs, enabling the endoscope to maintain performance while having a lower production cost, making it particularly suitable for disposable endoscopes.

[0021] 3. In this utility model, a self-lubricating pad is provided between the hemispherical housing of the lens and the lens tube. The self-lubricating pad ensures the smooth sliding of the two relative to each other, reduces frictional loss, and improves the stability of the connection. Attached Figure Description

[0039] The cables of the lighting module 4 and the camera module 7 both pass through the rear end of the housing 16 and extend axially along the lens tube 2 to connect with the connector 3.

[0040] The angle adjustment assembly includes a transmission rod 11 and a drive rod 13. The transmission rod 11 is disposed inside the lens tube 2.

The drive rod 13 is arranged perpendicular to the axial direction of the lens tube 2. When the drive rod 13 drives the rear end of the transmission rod 11 to move along the axial direction of the lens tube 2, one side of the housing 16 connected to the front end of the transmission rod 11 moves accordingly, thereby rotating the glass window 1 at the front end of the housing 16 and adjusting the angle of the glass window 1.

[0041] In this invention, the lens housing 16 can rotate relative to the inner wall of the lens tube 2, and does not interfere with the glass window 1 when rotating, and the glass window 1 always faces outward.

[0042] In this invention, the lens housing 16 is hemispherical, and the bottom surface (i.e. the front surface) of the hemispherical shape is flat, which is used to install the glass window 1.

[0043] Preferably, the angle adjustment assembly further includes a slot 14 and a sliding button 15; the slot 14 is formed on the wall of the lens tube 2; the sliding button 15 is slidably connected to the slot 14; the inner side of the sliding button 15 is fixedly connected to the outer end of the drive rod 13.

[0044] In this invention, by moving the sliding button 15 to the position within the slot 14, the drive rod 13 can be moved axially along the lens tube 2, and the transmission rod 11 connected to the drive rod 13 moves accordingly.

[0045] Preferably, the inner end of the drive rod 13 is connected to the transmission rod 11 via the first fixing ring 12; specifically, the inner end of the drive rod 13 is connected to the first fixing ring 12 (which can be fixedly connected), and the rear end of the transmission rod 11 is connected to the first fixing ring 12 (which can be hinged).

[0046] Preferably, the front end of the transmission rod 11 is connected to the housing 16 via a second fixing ring 10; specifically, the second fixing ring 10 is installed at the rear end of the housing 16; the front end of the transmission rod 11 is connected to the second fixing ring 10 (which may be hinged).

[0047] Preferably, a self-lubricating pad 9 is provided on the inner circumferential surface of the front end of the lens tube 2; the housing 16 is connected to the lens tube 2 through the self-lubricating pad 9.

[0048] In this invention, the self-lubricating pad 9 is made of silicone or rubber material with self-lubricating properties and has a low coefficient of friction; the self-lubricating pad 9 is annular and located on the inner wall of the front end of the lens tube 2, wrapping the outer side of the housing 16; the housing 16 is made of metal material, and the smooth metal housing 16 can slide on the surface of the self-lubricating pad 9.

[0049] In this invention, the lighting module 4 includes LED beads and a circuit board, and is connected to the connector 3 via a corresponding lighting cable 5. The camera module 7 is connected to the connector 3 via a corresponding image cable 8.

[0050] In this utility model, the connector 3 is used to connect with the corresponding endoscope device, to supply power to the camera module 7 and the illumination module 4, and to transmit the camera information obtained by the camera module 7 to other devices; the structure and arrangement of the lens, the connection between the lens and one end of the endoscope tube 2, and the structure and function of the connector 3 are all existing technologies in the industry, and will not be described in detail here.

[0051] In this invention, the actual needs of the endoscope can be met by designing a slot 14, a sliding button 15, a drive rod 13, and a transmission rod 11.

[0052] Example 2

[0053] The only difference between this embodiment and Embodiment 1 is that: the drive rod 13 is made of hard metal or plastic, and the transmission rod 11 is made of hard metal or plastic; the drive rod 13 is connected to the first fixing ring 12 by welding or bonding (it can be fixedly connected), and the two ends of the transmission rod 11 are respectively hinged to the first fixing ring 12 and the second fixing ring 10.

[0054] The working principle of this utility model is as follows: When the endoscope is used, its initial state is that the front plane of the lens (the plane of the glass window 1) forms a 30° angle with the normal of the endoscope tube 2 (which is the perpendicular line of the endoscope tube 2, perpendicular to the axis of the endoscope tube 2). Figure 3 and Figure 4 As shown); slide the sliding button 15 towards the front (i.e., towards the lens), thereby moving the drive rod 13 forward; since the fixed point of the transmission rod 11 is on one side of the curved surface at the rear of the lens, the transmission rod 11 moves forward and laterally, thereby applying an oblique thrust to the lens; the lens is wrapped by the self-lubricating pad 9, and the relative coefficient of friction between the two is low, so when subjected to the oblique thrust of the transmission rod 11, the side of the lens subjected to the force will slide forward, causing the lens to rotate to a set angle (e.g. Figure 5 and Figure 6 As shown), adjust the viewing angle of the glass window 1; move the sliding button 15 to the rear end (that is, the end closer to the connector 3), drive the drive rod 13 to move backward, thereby causing the transmission rod 11 to pull the lens backward, so that the lens angle is restored.

[0055] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0056] 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.
