Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to an anti-fogging device during laparoscope surgery. Background Art

[0002] Technological advances have made it possible to perform surgery through smaller incisions, which causes less damage to tissue than traditional surgery. Through a keyhole-sized incision, the surgeon can insert a tiny light source, camera, and surgical instruments. The surgeon uses the images transmitted to the monitor to guide the operation of the surgical instruments. This type of surgery is called laparoscopic surgery when performed in the abdominal cavity, arthroscopic surgery when performed in a joint, and thoracoscopic surgery when performed in the chest cavity.

[0003] During laparoscopic surgery, the lens may fog up due to the temperature difference between the lens and the abdominal cavity, or due to the energy platform blade burning the tissue, causing mist, tissue fluid splashing, and even vascular bleeding. At the same time, the lens may be easily damaged during use. Therefore, the utility model proposes an anti-fog device during laparoscopic surgery, which aims to meet the need to prevent the laparoscopic lens from fogging during laparoscopic surgery.

[0027] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more explicit definition of the protection scope of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0028] The terms "including" and "having" and any variations thereof in the specification and claims of the present utility model and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of the present utility model or the above-mentioned drawings are used to distinguish different objects rather than to describe a specific order.

[0029] See also Figure 1-7 The anti-fog device during laparoscopic surgery includes an anti-fog cup body 3, which is used for inserting a laparoscopic instrument 13 and solving the problem that the lens 14 is easily fogged. A cup neck 2 is fixedly arranged on the top of the anti-fog cup body 3, and a ring-shaped guard edge 1 is protruding outward from the top of the cup neck 2. The diameter of the guard edge 1 is smaller than the cup neck 2. The guard edge 1 is made of flexible material, which can not only play a certain limiting role on the laparoscopic instrument 13, but also the flexible material will not produce hard contact with the laparoscopic instrument 13, and has good protection.

[0030] The anti-fog cup body 3 is hollow inside to form a receiving space for inserting the lens 14 of the laparoscope instrument 13. The receiving space of the anti-fog cup body 3 contains saline 6, which can quickly dissipate the fog in the lens 14 to achieve the defogging effect. After the fog dissipates, the laparoscope instrument 13 can be taken out to continue working. This effectively solves the problem that the lens fogs due to the temperature difference between the lens and the abdominal cavity, or the fog caused by the energy platform blade burning the tissue, the splash of tissue fluid, and even the bleeding of blood vessels, and the lens is easily damaged during use.

[0031] A silicone pad 12 is fixedly arranged on the inner wall of the anti-fog cup body 3, and the silicone pad 12 includes a first pad 11, and the first pad 11 is fixedly arranged on the inner wall of the anti-fog cup body 3. A second pad 5 is fixedly arranged on the bottom of the first pad 11, and the second pad 5 is fixedly arranged on the bottom inner wall of the anti-fog cup body 3. The first pad 11 and the second pad 5 are integrally formed. The thickness of the second pad 5 is greater than that of the first pad 11, and can play an overall supporting role. The setting of the silicone pad 12 can protect the lens 14. When the lens 14 is inserted into the anti-fog cup body 13, it can avoid damage caused by contact and friction between the lens 14 and the anti-fog cup body 3, thereby playing a role of both anti-fogging and effective protection of the lens.

[0032] As an improvement of the above technical solution, the first soft pad 11 and the second soft pad 5 have the same internal structure. The second soft pad 5 includes a silicone base layer 52. An adhesive layer 51 is fixedly arranged on the outer side of the silicone base layer 52. The silicone base layer 52 is fixedly arranged on the bottom inner wall of the anti-fog cup body 3 through the adhesive layer 51. A high temperature resistant layer 53 is fixedly arranged on the side of the silicone base layer 52 away from the adhesive layer 51. A waterproof layer 54 is fixedly arranged on the side of the high temperature resistant layer 53 away from the silicone base layer 52. The silicone base layer 52 is fixedly arranged on the bottom inner wall of the anti-fog cup body 3 through the adhesive layer 51. The high temperature resistant layer 53 improves the high temperature resistance of the silicone soft pad 12. The waterproof layer 54 improves the waterproof performance of the silicone soft pad 12.

[0033] As an improvement of the above technical solution, a cup holder cover 4 is installed at the bottom of the anti-fog cup main body 3, and the cup holder cover 4 is communicated with the anti-fog cup main body 3. A moisture-proof base 7 is sealed and fixed inside the cup holder cover 4, and the moisture-proof base 7 and the cup holder cover 4 are detachably installed and fixed. The moisture-proof base 7 can provide moisture-proof protection for the cup holder cover 4, and at the same time ensure the sealing of the connection between the cup holder cover 4 and the anti-fog cup main body 3. The moisture-proof base 7 can be detachably connected to the cup holder cover 4, or can be sealed and fixedly connected.

[0034] In order to ensure the sealing of the connection between the cup holder cover 4 and the anti-fog cup body 3, an annular threaded plate 10 is fixedly arranged on the top of the cup holder cover 4, and an annular threaded groove 9 is opened at the bottom of the anti-fog cup body 3. The annular threaded plate 10 is threadedly inserted in the annular threaded groove 9, and an annular sealing ring 8 is fixedly arranged on the top of the annular threaded groove 9. After the annular threaded plate 10 is tightened, it abuts against the bottom of the annular sealing ring 8. Through the structures such as the annular threaded groove 9, the annular threaded plate 10 and the annular sealing ring 8, the annular threaded plate 10 is threadedly inserted in the annular threaded groove 9, and after the annular threaded plate 10 is tightened, it abuts against the bottom of the annular sealing ring 8, thereby ensuring the sealing firmness of the connection between the cup holder cover 4 and the anti-fog cup body 3;

[0035] Working principle and usage of the utility model:

[0036] When in use, the anti-fog cup body 3 is filled with saline liquid 6. If the lens 14 of the laparoscopic instrument 13 is fogged, the laparoscopic instrument 13 can be inserted into the anti-fog cup body 3. Placing the lens 14 in the anti-fog cup body 3 can quickly prevent fogging. After the fog dissipates, the laparoscopic instrument 13 is taken out to continue working. The first soft pad 11 fixedly arranged on the inner wall of the anti-fog cup body 3 and the second soft pad 5 fixedly arranged on the inner wall of the bottom of the anti-fog cup body 3 can protect the lens and avoid damage caused by contact and friction between the lens and the anti-fog cup body 3, thereby preventing fogging and effectively protecting the lens. The utility model has a simple structure, high practicality, low cost, and can be widely used in clinical practice.
