[0024] A specific embodiment, as shown in the figure, represents a preferred implementation of this utility model. A fixing device for a micromanipulation tube 14 for assisted reproduction mainly includes a box body 1 and a box cover 5. The opening of the box body 1 faces upward, and the box cover 5 covers the opening of the box body 1. The box cover 5 is equipped with a hook piece 3 of a snap fastener structure, and the box body 1 is equipped with a buckle body 2 of a snap fastener structure. The box body 1 and the box cover 5 are connected together by the hook piece 3 and the buckle body 2 of the snap fastener structure. The upper end face of the box body 1 has an array of multiple tube holes 21, and each tube hole 21 is movably placed in the tube hole 21. On opposite sides of the upper end face of the box body 1, there are a first protrusion 15 and a second protrusion 23 that are parallel to each other.

Parallel to the length direction of the first slide groove 29, the third slide groove 16 communicates with the first slide groove 29. Two first fixing rods 18 are vertically installed on the upper end face of the first connecting rod. The first fixing rods 18 extend out of the first protrusion 15 from the third slide groove 16 and are slidably connected inside the third slide groove 16. A first nut 17 is threaded onto the first fixing rod 18 and abuts against the upper end face of the first protrusion 15. Multiple first clamping rods 20 are installed on the side of the first connecting rod along its length direction. The multiple first clamping rods 20 are evenly distributed along the length direction of the first connecting rod, and the length direction of the first clamping rods 20 is perpendicular to the length direction of the first connecting rod. Each adjacent pair of first clamping rods 20 accommodates a... A first clamping rod 20 has multiple first arc-shaped slots 19 evenly distributed along its length. Each first arc-shaped slot 19 corresponds to a position of a pipe hole 21, located in front of the opening of the pipe hole 21, with its arc-shaped opening facing the pipe hole 21. The second component has the same structure as the first component, including a second connecting rod and multiple second clamping rods 27. The second connecting rod is slidably connected within a second sliding groove 22. Two second fixing rods 26 are vertically mounted on the upper end face of the second connecting rod. A fourth sliding groove 24 is formed on the upper end face of the second protrusion 23. The length direction of the groove 24 is parallel to the length direction of the second slide groove 22. The fourth slide groove 24 is connected to the second slide groove 22. The second fixing rod 26 extends out of the second protrusion 23 from the fourth slide groove 24. The second fixing rod 26 is slidably connected inside the fourth slide groove 24. A second nut 25 is threaded onto the second fixing rod 26. The second nut 25 abuts against the upper end face of the second protrusion 23. The multiple second arc-shaped bayonets 28 on the second clamping rod 27 are located behind the opening of the pipe hole 21. The arc-shaped openings of the second arc-shaped bayonets 28 face the pipe hole 21. The arc-shaped openings of the first arc-shaped bayonets 19 and the second arc-shaped bayonets 28 are directly opposite each other. The first arc-shaped bayonets 19 and the second arc-shaped bayonets 28 are clamped on the side wall of the operating tube 14.

[0026] A pressing assembly is installed inside the box cover 5. The pressing assembly includes a pressure plate 12, a spring 11, and multiple guide rods 9. The guide rods 9 are telescopic rods. One end of each guide rod 9 is vertically installed on the inner end face of the box cover 5, and the other end of each guide rod 9 is vertically installed on the pressure plate 12. A spring 11 is sleeved on each guide rod 9. The pressure plate 12 slides inside the box cover 5 along the axial direction of the guide rods 9. The lower end face of the pressure plate 12 abuts against the plug 13 of the operating tube 14.

[0027] This utility model is sterilized before use and can be used directly. The operating tubes 14 used in hospitals are generally of the same specification. When multiple operating tubes 14 need to be fixed, the box cover 5 is opened, exposing the tube hole 21 of the box body 1. The size of the tube hole 21 is larger than the diameter of the operating tube 14, allowing the operating tube 14 to be easily inserted into the tube hole 21. However, to prevent the operating tube 14 from shaking inside the tube hole 21 during movement, a clamping component is provided to hold the operating tube 14 placed in the tube hole 21. When multiple operating tubes 14 of the same specification need to be inserted into the tube hole 21, the clamping component needs to be moved so that it does not obstruct the top of the tube hole 21, thus avoiding affecting the insertion of the operating tube 14. When the clamping assembly needs to be moved, loosen the first nut 17 and the second nut 25 so that the first fixing rod 18 and the second fixing rod 26 are no longer fixed to the first protrusion 15 and the second protrusion 23. The first and second parts of the clamping assembly can be moved forward and backward, so that the first clamping rod 20 and the second clamping rod 27 can move forward and backward and no longer block the tube hole 21. When multiple operating tubes 14 are inserted into the tube hole 21, move the first and second parts so that the first arc-shaped locking slot 19 of the multiple first clamping rods 20 and the second arc-shaped locking slot 28 of the second clamping rod 27 clamp the side of each operating tube 14 respectively. Then tighten the first nut 17 and the second nut 25 so that the first and second parts are fixed to the first protrusion 15 and the second protrusion 23 by the first fixing rod 18 and the second fixing rod 26, so that the position of the first clamping rod 20 and the second clamping rod 27 is fixed, thereby fixing the operating tube 14 clamped between the first clamping rod 20 and the second clamping rod 27, so that the position of the operating tube 14 in the lateral direction is fixed. After the operating tube 14 is clamped by the clamping assembly, the lid 5 is placed over the opening of the box body 1 and secured to the box body 1 using a snap fastener. When the lid 5 is fixed to the box body 1, the tube plug 13 of the operating tube 14 abuts against the lower end face of the pressure plate 12. The pressure plate 12 is subjected to a vertical force, which compresses the spring 11, generating elastic force. Through the elastic force, the pressure plate 12 presses against the tube plug 13 of the operating tube 14, thus subjecting the tube plug 13 of the operating tube 14 to a vertical force, making it difficult for the tube plug 13 of the operating tube 14 to fall off the opening of the operating tube 14. The clamping assembly and pressing assembly of this application can operate multiple operating tubes 14 simultaneously, which is convenient and saves time. Furthermore, when the clamping assembly is not used, the tube hole 21 on the box body 1 can be used alone to temporarily place the operating tube 14, which is also convenient.

[0028] Furthermore, the inner surfaces of the first arc-shaped bayonet 19 and the second arc-shaped bayonet 28 are both provided with anti-slip pads, so that the clamping assembly can better clamp the operating tube 14.

[0029] Furthermore, the inner ring of the box cover 5 is provided with a retaining strip 10, and a fixing plate 8 is slidably connected between the inner end face of the box cover 5 and the retaining strip 10. The fixing plate 8 is parallel to the end face of the box cover 5, and a limiting hole is opened on the end face of the box cover 5. A limiting rod 7 is threadedly connected to the limiting hole. One end of the limiting rod 7 is rotatably connected to the fixing plate 8, and the other end of the limiting rod 7 extends out of the box cover 5. One end of the guide rod 9 is connected to the inner end face of the box cover 5 through the fixing plate 8. Because when the box cover 5 is closed on the box body 1, the spring 11 inside the box cover 5 is compressed and generates elastic force, which will increase the resistance to closing the box cover 5. In order to facilitate closing the box cover 5, a limiting rod 7 is provided on the box cover 5. One end of the limiting rod 7 is rotatably connected to the fixing plate 8. The distance between the fixing plate 8 and the inner end face of the box cover 5 is adjusted by the threaded connection of the limiting rod 7 in the limiting hole, so that the height of the pressure plate 12 installed at the lower end of the fixing plate 8 can be adjusted. When the lid 5 needs to be closed, rotate the limiting rod 7 upwards, causing the fixing plate 8 to move towards the inner end face of the lid 5. This causes the pressure plate 12 to move accordingly. When the lid 5 is closed on the body 1, the pressure plate 12 will not press against the plug 13 of the operating tube 14 when the spring 11 is in its natural state. After the lid 5 is fixed to the body 1, rotate the limiting rod 7 downwards, causing the fixing plate 8 to move towards the body 1. The pressure plate 12 moves towards the body 1 along with the fixing plate 8, pressing against the plug 13 of the operating tube 14. The spring 11 is compressed, and the resulting elastic force presses the pressure plate 12 against the plug 13 of the operating tube 14. The force on the plug 13 of the operating tube 14 can be adjusted by rotating the limiting rod 7 within the limiting hole. To prevent the limiting rod 7 from moving downwards too far, which could cause excessive pressure on the operating tube 14 from the pressure plate 12 and damage the operating tube 14, this application provides a baffle 10 around the inner ring of the housing 1. This limits the downward movement of the fixing plate 8, preventing the limiting rod 7 from moving downwards too far and thus protecting the operating tube 14. Furthermore, the other end of the limiting rod 7 is provided with a handle 6 for rotation, facilitating the rotation of the limiting rod 7.

[0030] Furthermore, a handle 4 is installed on the outer side of the lid 5. The two ends of the handle 4 are rotatably connected to two opposite sides of the lid 5, making it convenient to lift and carry the entire device using the handle 4. Furthermore, the handle 4 is a strip structure made of soft material, providing a comfortable grip.

[0031] Furthermore, a soft pad is provided at the bottom of the tube hole 21 to serve as a buffer and to protect the operating tube 14 placed inside the tube hole 21.

[0032] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
