Description

Technical Field

[0001] The utility model relates to the technical field of surgical medical instruments, in particular to a saliva suction tube and a saliva suction instrument. Background Art

[0002] During oral surgery, in order to ensure a clear view of the surgical area and prevent the large amount of blood, saliva and debris produced during the operation from affecting the doctor's observation and operation of the internal oral situation, effective suction measures need to be taken and attention must be paid to the principle of sterility.

[0003] Existing saliva suction tube systems for microsurgery typically require a complex connection process: the suction tube must be connected to the suction tube, which is then connected to the strong suction port via a long tube. This cumbersome connection method not only increases the complexity of the operation but can also significantly weaken the suction force of the suction tube due to the partial pressure passing through the extended tube. Due to insufficient suction, blood and saliva may not be aspirated promptly and thoroughly, affecting the surgical field of view and making the suction tube more susceptible to clogging. This not only affects the smooth progress of the operation but also poses a potential safety hazard to the patient. Summary of the Invention

[0021] In addition, in the present invention, descriptions such as "first" and "second" are only used for descriptive purposes and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but this must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0022] The present invention provides a saliva suction tube 100, such as Figure 1 As shown, the saliva suction tube 100 includes a tube head 110, a tube body 120, and a tube tail 130. Along the length of the saliva suction tube 100, the inner diameter of the tube head 110 gradually increases from the open end of the tube head 110 to the end near the tube body 120, and the inner diameter of the tube tail 130 first decreases and then increases from the open end to the end near the tube body 120.

[0023] The working principle and beneficial effects of the above technical solution are as follows: this design extends the saliva suction tube 100, and the tube tail 130 utilizes the Laval principle to enhance suction. The tube head 110 adopts an improved front-end small-caliber design, which can not only penetrate deep into the surgical area to promptly suction saliva, ensuring the principle of sterility, but also enhances suction and ensures the saliva suction effect, minimizes damage to the periodontal tissue of the teeth, and achieves a non-invasive effect. It has a simple design, strong reliability, and low cost, providing a simple solution for clinical situations where timely saliva suction cannot be achieved due to microsurgery.

[0024] It should be noted that the tail 120 of the saliva suction tube 100 includes a contraction section and an expansion section: First, the gas enters the contraction section of the tail 120 at a certain initial velocity. During this stage, the movement of the gas follows the principle that "when a fluid moves in a tube, the flow velocity is high where the cross-section is small, and low where the cross-section is large," so the airflow is continuously accelerated. When the airflow reaches the throat, its flow velocity is very high. When it reaches the expansion section, the motion characteristics of the high-speed fluid in the expansion section change, no longer following the aforementioned relationship between flow velocity and cross-sectional area. Instead, the larger the cross-sectional area, the faster the flow velocity. Therefore, when the airflow passes through the throat and enters the expansion section, its velocity is further accelerated, eventually reaching a maximum.

[0025] In one embodiment, the tube body 120 is a telescopic tube structure.

[0026] The working principle and beneficial effects of the above technical solution are as follows: after the suction force is enhanced, the extension tube can be pulled at will according to the needs of the operation, which not only satisfies the saliva suction effect but also ensures the principle of sterility.

[0027] In one embodiment, the open end of the tube tail 130 is provided with a connecting portion for connecting to a saliva suction device.

[0028] The working principle and beneficial effects of the above technical solution are: it is helpful to ensure the connection stability of the saliva suction tube 100 on the saliva suction device,

[0030] The working principle and beneficial effects of the above technical solution are: ensuring the structural stability of the pipe tail 130,

[0031] In one embodiment, along the length direction of the saliva suction tube 100 , the outer diameter of the tube head 110 gradually increases from the open end of the tube head 110 to the end close to the tube body 120 .

[0032] The working principle and beneficial effects of the above technical solution are: thereby ensuring a small overall caliber. The small caliber design facilitates deep penetration into the surgical area to suck out blood and saliva. It can not only penetrate into the surgical area to suck out saliva in time, ensuring the principle of sterility, but also helps to enhance suction force, ensure the saliva suction effect, reduce damage to the periodontal tissue of the teeth, and achieve a non-invasive effect.

[0033] In one embodiment, the saliva suction tube 100 further includes a shaping strip 111, which is disposed inside the tube head 110. Preferably, the shaping strip 111 is a copper wire.

[0034] The working principle and beneficial effects of the above technical solution are: the required angle can be bent according to needs to improve the saliva suction effect.

[0035] In one embodiment, the tube head 110 is made of soft plastic, such as TPE soft plastic material, and the tube tail 130 is made of hard plastic, such as PP hard plastic.

[0036] The working principle and beneficial effects of the above technical solution are as follows: the front end and the extension part are made of TPE soft rubber material, which is easy to shape, with a comfortable and soft surface, good touch, and easy to hold; the tail is made of PP hard plastic to facilitate fixing the tail structure, not easy to bend, and ensure the Laval structure to enhance suction.

[0037] Furthermore, the tube body 120 is an injection-molded structure of a soft rubber material and plastic over-molding, such as a TPE soft rubber material and PP plastic over-molding.

[0038] The working principle and beneficial effects of the above technical solution are: firm connection and easy bending.

[0039] An embodiment of the present application further provides a saliva suction device (not shown in the figure), which includes a saliva suction device and any one of the saliva suction tubes 100 described above, wherein the saliva suction device is detachably connected to the tube tail.
