[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0020] Please see Figure 1-4In this embodiment: a disposable duckbill cap-shaped transparent endoscope cap includes an endoscope transparent cap body 1. The inner wall of the top of the endoscope transparent cap body 1 is provided with a groove 2. A through hole 3 is provided on one side of the groove 2. A connecting strip 4 is provided above the groove 2. A limit bolt 5 is provided at one end of the connecting strip 4. An inner groove 6 is provided on the inner wall of the front end of the endoscope transparent cap body 1. A sliding groove 7 is provided on one side of the inner groove 6. A pressure piece 8 is provided inside the inner groove 6. A slider 9 is provided on one side of the pressure piece 8. A limit hole 10 is provided on the inner wall of the upper end of the pressure piece 8. A pull tab 11 is provided at the front end of the pressure piece 8.
[0021] Reference Figure 1-3 One end of the connecting strip 4 is fixedly connected to the inner wall of the transparent cap body 1 of the endoscope, and the other end of the connecting strip 4 is fixedly connected to one side of the limiting bolt 5; one end of the limiting bolt 5 extends through the inner wall of the through hole 3 and into the limiting hole 10, and the limiting bolt 5 is engaged with the limiting hole 10.
[0022] Specifically: By setting the connecting strip 4, the stability of the limit bolt 5 can be improved and the loss of the limit bolt 5 can be prevented; by using the cooperation between the limit bolt 5 and the limit hole 10, the stability of the tablet 8 can be improved and the shaking of the tablet 8 can be prevented during use.
[0023] Reference Figure 1 , Figure 2 and Figure 4 The pressure plate 8 is made of transparent silicone. The outer diameter of the pressure plate 8 matches the inner diameter of the inner groove 6, and the pressure plate 8 is fitted inside the inner groove 6.
[0024] Specifically: Using compression film 8 can not only fully expose the surgical field, but also reduce intraoperative bleeding and perforation.
[0025] Reference Figure 2-4 There are two sets of sliders 9, which are symmetrically installed on both sides of the pressure plate 8 and are slidably connected to the slide groove 7; there are two sets of limiting holes 10, which are symmetrically embedded in the inner wall of the upper end of the pressure plate 8.
[0026] Specifically: the cooperation between the slide groove 7 and the slider 9 can improve the stability of the movement of the tablet 8; by setting two sets of limiting holes 10, the tablet 8 can be limited to prevent it from moving on its own when not in use.
[0027] Reference Figure 1-4 The pull tab 11 is made of rubber and is fixedly installed at the front end of the pressure plate 8. The outer surface of the pull tab 11 is provided with anti-slip texture.
[0028] Specifically: By setting the pull tab 11, it is easier to remove the pressure plate 8, and the anti-slip texture can improve the anti-slip effect of the pull tab 11.
[0029] The working principle and usage process of this utility model are as follows: When using the endoscope transparent cap body 1, the operator installs the endoscope transparent cap body 1 at the front end of the endoscope. When using the endoscope transparent cap body 1, the doctor pulls out the pressure plate 8 by pulling out the pressure plate 11. The pressure plate 8 can not only fully expose the surgical field of view, but also reduce intraoperative bleeding and perforation. When the pressure plate 8 is pulled out, the cooperation of the sliding groove 7 and the sliding block 9 can improve the stability of the movement of the pressure plate 8. When the pressure plate 8 moves to the designated position, the bottom end of the limiting bolt 5 is inserted into the through hole 3 into the limiting hole 10. The cooperation of the limiting bolt 5 and the limiting hole 10 can improve the stability of the pressure plate 8 and prevent the pressure plate 8 from shaking during use. In this way, the usage effect of the endoscope transparent cap body 1 is improved.
