[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] like Figures 1 to 5 As shown, this utility model provides a disposable spinal endoscope, including a sheath module 1 and a handle module 2. The sheath module 1 includes a metal head end 11 and a metal sheath tube 12. The metal head end 11 and the metal sheath tube 12 are fitted with a clearance, and the metal head end 11 can rotate relative to the metal sheath tube 12. The metal head end 11 is provided with a water injection hole 111 and a lens hole 112. The lens hole 112 is sealed with a camera module 1121, an LED light 1123 and the front end of a spring tube 1124. The LED light source provides uniform illumination and reduces shadow areas during the operation. A signal line 1125 runs through the inside of the spring tube 1124. The outer diameter of the sheath module 1 is 2.3 mm, which can minimize surgical trauma.
[0028] Specifically, the handle module 2 includes a handle 21, a transmission module 22, a circuit board housing 23, an O-ring seal 24, and a water inlet connector 25. The front end of the handle 21 is connected to the end of the metal sheath 12 by adhesive. The water inlet connector 25 is connected to the mounting hole at the front end of the handle 21. The metal sheath 12 has a small hole at the position opposite to the water inlet hole 111, and the O-ring seal 24 is fixed inside the O-groove of the handle 21 at the end of the metal sheath 12 to prevent water from flowing into the handle 21.
[0029] Furthermore, the transmission module 22 includes a rotating shaft 221, a limiting shaft 222, a limiting slider 223, and a compression spring 224. The positioning post of the rotating shaft 221 passes through the limiting slider 223 and the compression spring 224 and connects with the positioning hole of the limiting shaft 222 to form the transmission module 22. The cuboid of the limiting shaft 222 cooperates with the rectangular groove of the circuit board housing 23, so that the circuit board housing 23 and the rotating mechanism can rotate synchronously.
[0030] Furthermore, the cylinder at the front end of the rotating shaft 221 engages with the cylindrical groove inside the handle 21. The handle 21 has an axial limiting groove 227 and an axial positioning groove 228 respectively. The axial limiting groove 227 is designed with a boss structure that can engage with the axial limiting block 225 of the rotating shaft 221 to limit the rotation angle to 300°.
[0031] It is worth noting that the axial positioning block 226 on the limit slider 223 cooperates with the axial positioning groove 228 at the end of the handle 21 to keep the limit slider 223 in both raised and lowered states.
[0032] It is worth noting that the camera module 1121 includes a camera module 1122, an LED light 1123, a spring tube 1124, a signal line 1125, a circuit board 1126, and a system connector 1127. The camera module 1122 is model OVM6946. The spring tube 1124 wraps around the signal line 1125 and passes through the handle 21, the O-ring 24, the rotating shaft 221, and the limiting shaft 222. Finally, it is glued to the end of the limiting shaft 222. The remaining signal line 1125 is connected to the circuit board 1126. The camera module 1121 provides high-definition image output (≥1080P) and has a wide viewing angle (≥120°) to ensure the clarity and breadth of the surgical field of view.
[0033] It is worth mentioning that there are two LED lights 1123, located on both sides of the lens. The model number of the LED lights 1123 is MK-PB0301WE-010FN.
[0034] It is worth emphasizing that a circuit board 1126 is placed inside the circuit board housing 23. One end of the circuit board 1126 is connected to the signal line 1125, and the other end of the circuit board 1126 is connected to the system connector 1127. The circuit board 1126 adopts advanced image processing algorithms, such as color correction and image stabilization technology, to improve the realism and stability of the image.
[0035] Among them, LED light 1123, signal line 1125, circuit board 1126 and system connector 1127 are existing technologies and will not be described in detail; at the same time, this utility model also includes power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.
[0036] Working principle: Before starting surgery, medical staff insert the system connector 1127 into the main unit. During use, the metal sheath 12 of the spinal endoscope is inserted into the pre-cut skin incision. The metal tip 11 is controlled by the circuit board 1126 via the signal line 1125 to move to the area to be observed. The lens hole 112 in the metal tip 11 is used for observation. The LED light 1123 provides uniform illumination. The camera module 1121 provides clear high-definition image output with a wide viewing angle, ensuring the clarity and breadth of the surgical field. Then, the limiting slider 223 is pushed up and rotated clockwise until the axial limiting block 225 is fixed in the axial limiting groove 227. Subsequently, the circuit board housing 23 is rotated to drive the limiting shaft 222 and the rotating shaft 222. 21. The rotation of the spring tube 1124 and even the lens, the cuboid of the limiting shaft 222 and the rectangular groove of the circuit board housing 23 cooperate, so that the circuit board housing 23 and the rotating mechanism can rotate synchronously. After observing and displaying the image to a reasonable angle, the left-hand limiting slider 223 is reset. Under the action of the compression spring 224, the limiting slider 223 presses the limiting shaft 222, thereby solving the problems of high risk of cross-infection, high equipment maintenance cost, limited surgical field of view, insufficient operational flexibility and poor compatibility of surgical instruments in the existing technology. By designing a disposable endoscope, aseptic operation is ensured. At the same time, the optical performance, operating mechanism and compatibility of the endoscope are optimized to improve surgical efficiency, reduce surgical risks and improve the quality of postoperative recovery for patients.
