Description

Technical Field

[0001] This utility model belongs to the field of arthroscopy, and in particular relates to a multi-angle adjustable handle for arthroscopic endoscopes and the endoscope thereof. Background Technology

[0002] Arthroscopic endoscopes are widely used in medical, industrial, and other fields, primarily for inspecting the internal structures of the human body, tubes, or equipment. Traditional rigid arthroscopic endoscopes typically consist of a rigid tube, a lens, and an image acquisition device.

[0003] However, most rigid arthroscopic endoscopes currently designed require rotating a handle to adjust the viewing angle, which makes operation complicated and, in many cases, cannot guarantee that the image to be acquired is in the center position because the angle of the insertion part and the acquisition unit is fixed. Currently, a snake-bone structure is set at the front end. However, the current snake-bone adjustment device mostly uses a rotating disk to control the tension of two traction ropes to complete the snake-bone adjustment. However, the existing adjustment structure cannot accurately adjust the snake-bone structure with four traction ropes. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] To address the problem that existing adjustment mechanisms cannot achieve accurate adjustment, the applicant proposes a multi-angle adjustment handle for arthroscopic endoscopes.

[0020] Please see Figure 3 , Figure 3This is a schematic diagram of the traction rope installation of a multi-angle adjustment handle for an arthroscopic endoscope provided in an embodiment of this application. The multi-angle adjustment handle for an arthroscopic endoscope includes: a pushing element 1, a connecting rod 2, and a handle 3.

[0021] One end of the connecting rod 2 is connected to the pushing element 1; the handle 3 is equipped with an adjusting device 32, an elastic device 31 and a traction device 33. The adjusting device 32 is connected to the other end of the connecting rod 2. The elastic device 31 is located between the pushing element 1 and the adjusting device 32 and is sleeved on the outside of the connecting rod 2. The traction device 33 is connected to the adjusting device 32.

[0022] As described above, a contact platform 35 can be provided inside the handle 3. The contact platform 35 has four second through holes 351 evenly distributed around the circumference for the traction rope 331 to pass through, ensuring that the traction rope 331 can run smoothly and stably inside the handle 3 without being disturbed. The circumferential distribution of the second through holes 351 can disperse the pressure of the traction rope 331 on the inside of the handle 3, which can improve the durability of the handle 3.

[0023] To ensure the stability of connecting rod 2 during adjustment, and to significantly reduce resistance during operation, see [reference needed]. Figure 5 , Figure 5 This is a structural diagram of an elastic device for a multi-angle adjustment handle of an arthroscopic endoscope provided in an embodiment of this application. The elastic device 31 includes an elastic outer ring 311, an elastic support column 312, and an elastic inner ring 313. Multiple elastic support columns 312 are provided between the elastic outer ring 311 and the elastic inner ring 313, which can ensure support for the connecting rod 2 and avoid excessive resistance to its movement.

[0024] Meanwhile, the elastic outer ring 311 and the elastic inner ring 313 can be made of high-strength and highly elastic materials to ensure the overall stability and durability of the structure. The elastic support column 312 is not simply set upright, but is set in an arc-shaped incline. This design cleverly distributes the vertical and lateral loads from the connecting rod 2, improving the efficiency of the support. Moreover, through the optimization of its incline angle, the frictional resistance that the connecting rod 2 may encounter during the movement is also reduced, ensuring the smoothness and accuracy of the movement. The elastic support column 312 can also ensure that it can maintain the best elastic deformation and recovery ability under different working conditions, thereby improving the applicability and reliability of the elastic device 31.

[0025] See Figure 2 , Figure 4 , Figure 2 This is a diagram showing the internal structure of a multi-angle adjustment handle for an arthroscopic endoscope, as provided in an embodiment of this application. Figure 4This is a schematic diagram of the adjustment device and connecting rod of a multi-angle adjustment handle for an arthroscopic endoscope provided in this application embodiment. The adjustment device 32 includes an adjustment disc 321 and a mounting frame 322. The mounting frame 322 is fixedly installed on the inner wall of the handle 3 body by multiple evenly distributed support columns. These support columns ensure the stability of the mounting frame 322. The mounting frame 322 is provided with a mounting ball 3221, which can be made of wear-resistant and self-lubricating material to reduce friction and improve rotational smoothness. Four circumferentially evenly distributed traction rope 331 mounting points 3211 are provided on the outer side of the adjustment disc 321. A first groove 3212 for cooperating with the mounting ball 3221 is provided at the center of the inner side of the adjustment disc 321. The geometry of the first groove 3212 matches the outer contour of the mounting ball 3221, ensuring a tight fit and smooth rotation between the two. This arrangement ensures that the adjustment disc 321 can rotate freely around the mounting ball 3221, achieving unobstructed free rotation. Meanwhile, the mounting ball 3221 is movably installed in the first groove 3212, which also securely connects the adjustment plate 321 and the mounting bracket 322, ensuring both the flexibility of adjustment and the overall stability and durability of the structure.

[0026] In addition, the adjusting plate 321 is also provided with a second groove 3213 for movably connecting with the connecting rod 2. The connecting rod 2 and the second groove 3213 can be connected by thread or by plugging, and the two connection methods are as follows: The plug-in connection allows for the installation of a guide groove and a locking mechanism within the second groove 3213. After one end of the connecting rod 2 is smoothly inserted through the guide groove, it is fixed by the locking mechanism. This connection method also facilitates quick installation and disassembly, improving work efficiency.

[0027] The threaded connection allows for the installation of an internal thread on the inner wall of the second groove 3213 that matches the external thread of the connecting rod 2. Rotating the connecting rod 2 achieves a tight lock between the two. This connection method is not only stable and reliable but also provides good vibration resistance. Whether threaded or plug-in, the detachable connection method provided in this application greatly facilitates the installation and processing of the adjusting device 32, and also greatly facilitates subsequent maintenance and replacement.

[0028] See Figure 3 , Figure 3This is a schematic diagram of the traction rope installation of a multi-angle adjustment handle for an arthroscopic endoscope provided in this application embodiment. The traction device 33 includes a traction rope 331 and a sleeve 332. The handle 3 can be equipped with four traction ropes 331. The traction ropes 331 are equipped with sleeves 332 except for the two ends. The sleeves 332 are equipped with abutment bosses 3321, which are located on the side of the abutment 35 near the insertion part 4. When the traction ropes 331 are installed, they pass through the second through hole 351, the first through hole 341 and the mounting point 3211 in sequence. When the movement of the pushing element 1 drives the adjusting disk 321 to rotate around the mounting ball 3221, the traction of the traction ropes 331 is completed. The diameter of the abutment bosses 3321 should be larger than the diameter of the second through hole 351 to ensure the smooth movement of the traction ropes 331 relative to the sleeves 332.

[0029] In this embodiment, a guide plate 34 may also be provided inside the handle 3, and the guide plate 34 is provided with a first through hole 341, see [link to documentation]. Figure 6 , Figure 6 This application provides a structural diagram of a guide plate for a multi-angle adjustable handle of an arthroscopic endoscope. In this embodiment, the guide plate 34 has four first through holes 341 evenly distributed along its circumference. The first through holes 341 can be inclined, and their inclination angle is precisely calculated to be the angle from the installation point 3211 to the second through hole 351, which can play a guiding role and effectively avoid entanglement or interference problems caused by unreasonable paths. At the same time, in order to allow the traction rope 331 to pass smoothly through the first through holes 341 and reduce friction and wear, rounded chamfers can be used at both ends of the first through holes 341. The rounded chamfers not only improve the smoothness of the structure, but also help to disperse stress and extend the service life of the guide plate 34 and the traction rope 331.

[0030] See Figure 1 , Figure 1 This application provides an overall structural diagram of a multi-angle adjustable handle for an arthroscopic endoscope. It includes an insertion part 4 and an adjustable front end 5. The insertion part 4 serves as a bridge connecting the handle 3 and the adjustable front end 5. One end of the insertion part 4 is connected to the handle 3, ensuring the continuity and stability of the entire device during operation. The other end of the insertion part 4 is connected to the adjustable front end 5, allowing medical personnel to flexibly adjust the position and angle of the adjustable front end 5 according to actual needs to adapt to different environments. A snake-bone structure is provided at the end of the adjustable front end 5 near the insertion part 4. The snake-bone structure, with its excellent flexibility and strength, provides the front end with omnidirectional bending and rotation capabilities, greatly expanding the applicability of the device. An image acquisition unit is provided at the end away from the insertion part 4, which can capture images within the surgical field of view in real time, providing doctors with clear and intuitive visual feedback, greatly improving the accuracy and safety of the surgery.

[0031] Additionally, the device includes a main unit connection cable 6, which can be positioned on the side of the handle 3. This avoids direct interference with the pushing element 1, ensuring smooth and stable operation and improving user comfort. Positioning the main unit connection cable 6 on the side of the handle 3 allows medical personnel to grip it more naturally without worrying about interference or restriction from the cable, enabling them to focus more on the surgical procedure itself. Furthermore, this design helps reduce wear and tear on the cable caused by frequent movement or pulling, extending the overall lifespan of the device.

[0032] Working principle: One end of each of the four traction ropes 331 used to adjust the snake skeleton is fixed to the mounting point 3211 on the adjustment plate 321. This can be achieved by welding or crimping. During use, the movement of the pushing element 1 drives the adjustment plate 321 to rotate around the mounting ball 3221, thus tractioning the snake skeleton traction ropes 331 and controlling the snake skeleton's posture. At the same time, the mounting points 3211 are set relatively, so any angle adjustment will not cause the two symmetrically set traction ropes 331 to interfere with each other. This allows for full-angle adjustment, which can be done by adjusting the pushing element 1 alone.

[0033] By simply moving component 1, the snake bone can be adjusted to any angle without complicated operations or additional adjustment steps, greatly improving the ease of use and operational efficiency of the device and providing a more reliable and convenient solution for medical surgery.

[0034] This application also provides an endoscope to solve the current problem of endoscope angle. The handle 3 is provided with two horizontally arranged elastic outer rings 311. The connecting rod 2 is installed through the elastic outer rings 311. The elastic outer rings 311 are installed to stabilize the connecting rod 2 in the initial position when no external force is applied, so as to ensure that it remains concentric with the handle 3 when no external force is applied to the connecting rod 2. At this time, the snake bone is in a vertical state and the endoscope is at zero angle. At the same time, there is a gap between the two elastic outer rings 311 to avoid excessive resistance when the connecting rod 2 is adjusted.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
