Detailed implementation manners

[0022] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model, and cannot be construed as a limitation of the present utility model.

[0023] Embodiments of the present utility model: As Figures 1 - 5 shown, an open - type electronic endoscope includes a handle 1. A first working channel is provided in the upper part of the handle 1. A mirror tube 2 is fixedly provided on the handle 1. A mirror tube cover plate 3 is movably mounted on the mirror tube 2. A second working channel is formed between the mirror tube cover plate 3 and the mirror tube 2, and the first working channel is connected to the second working channel.

[0024] By providing a movable mirror tube cover plate 3 on the mirror tube 2, the size of the second working channel can be adjusted by adjusting the position of the mirror tube cover plate 3, so that the second working channel can pass through intervertebral fusion devices of different sizes.

[0025] In a specific embodiment, the handle 1 is in the shape of a pistol grip. A first groove 4 is formed at the top of the handle 1. A handle cover plate 5 is provided at the top of the handle 1. A second groove 6 is formed on the handle cover plate 5. The first groove 4 and the second groove 6 form a first working channel.

[0026] The handle cover plate 5 is designed to be openable and closable. The size of the first working channel allows most instruments and intervertebral fusion cages to pass through. When the intervertebral fusion cage is too large to pass through the first working channel, the handle cover plate 5 can be opened to make the top of the handle 1 in an open structure, so that the intervertebral fusion cage can be directly sent into the second working channel.

[0027] Further, two mounting tubes 7 are fixedly provided on one side of the first groove 4 at the top of the handle 1. Two mounting holes 8 are formed on the other side of the first groove 4 at the top of the handle 1. The two mounting holes 8 communicate with the inner space of the handle 1. One side of the handle cover plate 5 is rotatably connected to the mounting tube 7 through a rotating shaft 9. Two limiting posts 10 are formed on the other side of the handle cover plate 5. The two limiting posts 10 are opposite to the two mounting holes 8 in position.

[0028] A dial 11 is slidably installed in the handle 1. Two limiting rods 12 are formed on the dial 11. A limiting hole 13 is formed on the limiting post 10. The limiting rod 12 is inserted into the limiting hole 13. A dial block 14 is fixedly provided on the side surface of the dial 11. A dial block mounting hole 15 is formed on the side wall of the handle 1. One end of the dial 11 is fixedly provided with a spring 16.

[0029] There is a groove in the handle 1 for restricting the moving direction of the dial 11. When the handle cover plate 5 is closed, the two limiting posts 10 on the handle cover plate 5 enter the handle 1 through the two mounting holes 8. The axes of the two limiting rods 12 on the dial 11 are parallel to the axis of the first groove 4. Oblique guide sliding surfaces are formed at the ends of the two limiting rods 12. After the limiting posts 10 enter the handle 1, they contact and press the limiting rods 12 on the two limiting rods 12, so that the dial 11 moves towards the direction close to the lens tube 2 and compresses the spring 16 at the same time. When the limiting hole 13 on the limiting post 10 is coaxial with the limiting rod 12, the dial 11 moves reversely under the action of the spring 16 to make the two limiting rods 12 inserted into the limiting holes 13 on the two limiting posts 10, realizing the locking of the handle cover plate 5.

[0030] When it is necessary to open the handle cover plate 5, push the dial block 14 with a finger to make the dial 11 move towards the direction close to the lens tube 2 and compress the spring 16. When the dial block 14 slides to the end of the dial block mounting hole 15, the two limiting rods 12 are separated from the limiting holes 13. At this time, flip the handle cover plate 5 to open the handle cover plate 5, release the dial block 14, and the dial 11 moves away from the lens tube 2 under the action of the spring 16 until the dial block 14 moves to the other end of the dial block mounting hole 15.

[0031] Furthermore, a mirror tube mounting column 17 is formed on the handle 1, one end of the mirror tube 2 is plugged into and fixedly connected to the mirror tube mounting column 17, a third groove 18 is formed on the top of the mirror tube 2, and a fourth groove 19 is formed on the mirror tube cover plate 3, and the third groove 18 and the fourth groove 19 constitute a second working channel.

[0032] After the mirror tube 2 is plugged and connected to the mirror tube mounting column 17, it can be fixed by bonding, screwing, or snapping, and the fixing method can be selected according to needs. The shape and size of the third groove 18 on the mirror tube 2 are exactly the same as the shape and size of the first groove 4 on the handle 1. When the mirror tube 2 is fixed on the mirror tube mounting column 17, the first groove 4 is connected to the third groove 18 and the connection position is completely aligned.

[0033] In this embodiment, the mirror tube cover plate 3 is a U-shaped plate, and a mounting seat 21 is fixedly arranged at one end of the mirror tube cover plate 3. The lower part of the mounting seat 21 is a U-shaped structure. A limiting groove 22 is formed on the inner wall of the U-shaped structure on the mounting seat 21, and a limiting boss 20 is formed on the outer wall of the mirror tube mounting column 17. The limiting groove 22 is connected to the limiting boss 20 by clamping. A clamping plate 23 is formed at one end of the mirror tube cover plate 3 away from the handle 1.

[0034] Through the cooperation between the upper limit groove 22 on the mounting seat 21 and the limit boss 20 on the mirror tube mounting column 17, the mirror tube cover 3 can only move up and down but cannot move axially. In order to facilitate the position adjustment of the mirror tube cover 3, a spherical groove is preferably processed on one side of the upper end of the mounting seat 21, so that the user can easily hold the upper end of the mounting seat 21 to prevent slipping.

[0035] A clamping plate 23 is provided at the end of the scope tube cover plate 3. The clamping plate 23 can facilitate the end of the scope tube cover plate 3 to be pressed against the upper vertebral plate where the intervertebral fusion device is to be implanted, thereby improving the accuracy of the position of the intervertebral fusion device entering the intervertebral space.

[0036] Furthermore, a camera installation channel 24 , a lighting channel 25 and a flushing channel 26 are formed in the mirror tube 2 . The camera installation channel 24 is located in the middle, and a lighting channel 25 and a flushing channel 26 are respectively arranged on both sides of the camera installation channel 24 .

[0037] A camera 27 is provided in the camera installation channel 24, an optical fiber 28 is provided in the lighting channel 25, and a wiring harness protective cover 29, two water inlet connectors 30 and an optical fiber plug 31 are provided at the tail end of the handle 1.

The two flushing channels 26 are respectively connected to the two water inlet connectors 30 through water pipes, and one end of the optical fiber 28 is fixedly connected to the optical fiber plug 31.

[0038] The camera 27 is used to collect image information. The data line of the camera 27 passes through the wire harness protective sleeve 29 and extends out of the handle 1 and then is connected to the intelligent terminal. The intelligent terminal can be a PC computer, a laptop computer, a mobile phone, an IPD or a dedicated host. The intelligent terminal can analyze the image information collected by the camera 27 and display it through a display. The two water inlet connectors 30 are connected to the flushing device, and water is supplied through the flushing device to enable the electronic endoscope to have a flushing function. The fiber optic plug 31 is connected to the light source, and the light emitted by the light source is transmitted to the end of the lens tube 2 through the optical fiber 28 to achieve illumination. The intelligent terminal, the flushing device, and the light source are all prior arts, and their specific structures and principles will not be described in detail in this embodiment.

[0039] A plurality of buttons 32 are further arranged on the handle 1. A button circuit board 33 is arranged inside the handle 1. The buttons 32 are installed on the button circuit board 33. The data line of the button circuit board 33 passes through the wire harness protective sleeve 29 and extends out of the handle 1 and is connected to the intelligent terminal. The functions of the buttons 32 can be customized according to requirements, such as for shooting, taking pictures, adjusting brightness, etc.

[0040] The working principle of the present utility model: During operation, the lens tube cover plate 3 is covered on the lens tube 2. The limiting groove 22 on the lens tube cover plate 3 is snap-connected with the limiting boss 20 on the lens tube mounting post 17. After the wound is gradually expanded by the sleeve, the ends of the lens tube 2 and the lens tube cover plate 3 are inserted into the wound site and reach the interlaminar space where fusion is required. The clamping plate 23 on the lens tube cover plate 3 is abutted against the upper edge of the diseased lamina. If the selected intervertebral fusion cage is of a large size, the handle cover plate 5 needs to be toggled to open the first groove 4 to make the first groove 4 in an open state. Then, hold the mounting seat 21 and lift it upward to move the lens tube cover plate 3 upward to expand the second working channel. When the second working channel is suitable for the intervertebral fusion cage to pass through, the intervertebral fusion cage is placed and implanted into the lamina space.

[0041] During the process of implanting the intervertebral fusion cage, the light emitted by the light source is transmitted to the end of the lens tube 2 through the optical fiber 28 to provide illumination. The camera 27 collects the image information of the lamina and sends it to the intelligent terminal. After the intelligent terminal analyzes the image information, it is displayed through a display. The display of the picture helps to improve the accuracy of the implanting position of the intervertebral fusion cage and ensure the surgical quality.

[0042] The structure, features and effects of the present utility model have been described in detail based on the embodiments shown in the drawings.
