Description

Portable oral clinical saliva aspirator

Technical Field

The utility model relates to the technical field of oral saliva suction, in particular to a portable oral clinical saliva suction device.

Background

In oral clinical treatment, complicated operations are often performed in narrow anatomical structures. Such as the treatment of complex root canal, the extraction of broken root canal internal instruments, and various intra-oral narrow part surgical treatments, such as the extraction of broken root of complex tooth extraction, root tip surgery, etc. Therefore, in order to ensure accurate, effective and safe operation of a narrow anatomical part, the surgical field must be clear in the treatment process.

Two factors in oral clinical treatment can directly influence the surgical field definition: (1) the space in the oral cavity is narrow and the illumination is insufficient: (2) the presence of liquids, including ultrasonic cooling water, blood, exuded liquids, root canal flushing solutions, etc., is unavoidable in oral treatment procedures, and can directly hamper the accuracy of the operator's view of the surgical field. For the former, good illumination and enlarged view can be provided by a surgical microscope, so that a doctor can more clearly observe structures such as a marrow cavity, a root canal and the like; for the latter, it is necessary to remove fluids from the surgical field in time, particularly in small anatomical structures, which is critical to improving oral clinical procedure efficiency, accuracy, safety.

When the oral cavity dental treatment and the oral correction are adhered and repaired, saliva and flushing water in the oral cavity are removed in time, the dental surface of the treatment part is prevented from being polluted again, the electric saliva aspirator is used for a conditional hospital, the effect of the electric saliva aspirator is good, but the electric saliva aspirator is connected with a dental chair through a thicker connecting power line, the taking is complicated, only one saliva aspirator can be provided, and the effect is poor for patients with more saliva and accurate saliva aspiration at the same time; unconditional hospitals use multi-purpose reels and cotton balls to absorb and isolate moisture. Not only is the trouble of the operator increased, but also the curative effect of clinical tooth erosion is affected; there are reports of suction using a manually aspirated syringe, but this requires both hands of the operator, which is inefficient and difficult to popularize.

Most of the existing oral clinical saliva sucking devices are connected with an oral dental chair, and the taking is complicated due to the fact that connecting wires are arranged; and the dental chairs are usually provided with only one saliva aspirator port, when the operation is complicated such as adhesion of a mandibular bracket in orthodontic lingual correction or patient saliva is more, only one saliva aspirator is insufficient to prevent saliva contamination, and a portable saliva aspirator is often required urgently by an dentist at this time. Therefore, the application focuses on clinical demands and the defects of the prior art, and designs the special portable saliva aspirator aiming at temporary demands, thereby providing convenient and reliable support for the convenience of oral clinical operation. The method is simple and convenient to operate, and meets the design requirement of repeated use.
