Description

Technical Field

[0001] This utility model relates to the field of oral auxiliary instruments technology, specifically a surgical oral suction device. Background Technology

[0002] The oral cavity is the beginning of the digestive tract. It connects to the outside world through the mouth fissure in the front and continues to the pharynx through the pharyngeal isthmus in the back. The oral cavity contains organs such as teeth and tongue. When performing surgical treatment on a patient's oral cavity, it is necessary to use a saliva suction tube to remove foreign objects from the patient's oral cavity.

[0003] However, most existing surgical oral suction devices use flat-mouthed metal suction tubes to treat patients' mouths. The combination of flat-mouthed suction tubes and obstructed metal suction tubes is not very effective, resulting in a decrease in the treatment effect inside the patient's mouth.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings and proposed a surgical oral suction device. Utility Model Content

[0005] The purpose of this invention is to provide a surgical oral suction device to solve the problem mentioned in the background art of low efficiency in combining and converting flat-mouth suction tubes and obstructed metal suction tubes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a surgical oral suction device, comprising a saliva suction tube, the end of which is detachably connected to a saliva suction flat head, the inner wall of which is detachably connected to a first extension tube, the outer wall of which is fixedly connected to a second extension tube, one end of which is fixedly connected to a negative pressure connector, the outer wall of which is provided with a first external spiral, the connection between the inner wall of which is connected to the first external spiral of which is provided with a first internal spiral, the inner wall of which is threadedly connected to a liquid accumulation filter screen, the outer wall of which is provided with a second external spiral, the connection between the inner wall of which is connected to the second external spiral of which is provided with a second internal spiral, the outer wall of which is provided with a third external spiral, and the connection between the inner wall of which is connected to the third external spiral of which is provided with a third internal spiral.

[0007] Furthermore, the saliva suction tube and the first extension tube and the second extension tube are all made of metal.

[0008] Furthermore, the angle between the connection points of the first extension tube and the second extension tube is 135°.

[0009] Furthermore, the outer wall of the liquid collection filter screen has a convex shape.

[0010] Furthermore, the first extension tube is connected to the saliva suction tube via a first outer spiral and a first inner spiral, forming a detachable structure.

[0011] Furthermore, the saliva suction flathead is detachable from the saliva suction tube via a third outer spiral and a third inner spiral.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, through the design of a saliva suction tip and a saliva filter, enhances the simultaneous filtration of saliva and impurities during different surgical stages when performing oral treatments via a saliva suction tube. When suctioning saliva from the lower larynx, the saliva filter is conveniently installed and replaced via a second external spiral and a second internal spiral, allowing for efficient adsorption of saliva. Simultaneously, when suctioning the surgical area, the first internal spiral and the first external spiral connect the saliva suction tip, which is threaded to the suction tube, to the first extension tube. This allows a single suction tube to suction both saliva and the surgical area, ensuring sterility and preventing contamination of the surgical area by the saliva-laden suction tube tip. This improves the adaptability of the saliva suction tube at different treatment stages, ultimately enhancing the overall oral treatment outcome. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] Example: Figures 1-4 As shown, a surgical oral suction device includes a suction tube 1, a suction head 2 detachably connected to the end of the suction tube 1, a first extension tube 3 detachably connected to the inner wall of the suction tube 1, a second extension tube 4 fixedly connected to the outer wall of the first extension tube 3, a negative pressure connector 5 fixedly connected to one end of the second extension tube 4, a first external spiral 6 provided on the outer wall of the first extension tube 3, a first internal spiral 7 provided at the connection between the inner wall of the suction tube 1 and the first external spiral 6, a liquid filter screen 8 threadedly connected to the inner wall of the first extension tube 3, a second external spiral 9 provided on the outer wall of the liquid filter screen 8, a second internal spiral 10 provided at the connection between the inner wall of the first extension tube 3 and the second external spiral 9, a third external spiral 11 provided on the outer wall of the suction head 2, and a third internal spiral 12 provided at the connection between the inner wall of the suction tube 1 and the third external spiral 11.

[0021] Furthermore, the saliva suction tube 1, the first extension tube 3, and the second extension tube 4 are all made of metal, which helps to improve the convenience of disinfection and sterilization of the saliva suction tube 1 during long-term use.

[0022] Furthermore, the angle between the connection points of the first extension tube 3 and the second extension tube 4 is 135°, which facilitates the convenient assembly and multi-functional use of the saliva suction tube 1.

[0023] Furthermore, the outer wall of the liquid filter 8 has a convex shape, which facilitates the blocking of the sucked-up items.

[0024] Furthermore, the first extension tube 3 forms a detachable structure with the saliva suction tube 1 through the first outer spiral 6 and the first inner spiral 7, which facilitates the combined use of the first extension tube 3 and the saliva suction tube 1 through the threaded connection of the first outer spiral 6 and the first inner spiral 7, thereby improving the multi-functional use of the saliva suction tube 1 in the patient's oral cavity.

[0025] Furthermore, the saliva suction head 2 forms a detachable structure with the saliva suction tube 1 through the third outer spiral 11 and the third inner spiral 12. This facilitates the threaded connection between the saliva suction head 2 and the saliva suction tube 1 through the threaded connection of the third outer spiral 11 and the third inner spiral 12, thereby achieving the effect of switching the use of the saliva suction tube 1 in different treatment states of the patient's oral cavity.

[0026] Working principle: When using this surgical oral aspirator, during oral treatment of a patient through the suction tube 1, in order to improve the synchronous filtration effect of adsorbing saliva and impurities inside the patient's mouth at different surgical stages, the saliva filter 8 can be easily installed and replaced by connecting the second outer spiral 9 and the second inner spiral 10 through the threads of the second outer spiral 9 and the second inner spiral 10. This achieves efficient adsorption of saliva inside the patient's mouth. At the same time, when suctioning the surgical area of ​​the patient's mouth, the saliva suction head 2, which is threaded to the suction tube 1, is connected to the first extension tube 3 through the threaded connection of the first inner spiral 7 and the first outer spiral 6. This improves the effectiveness of the suction tube 1 in adjusting its use in different treatment stages of the oral cavity, thereby improving the oral treatment effect for the patient.

[0027] This is how this type of surgical oral suction device works.
