Description

Switchable Multifunctional Suction Tube for Oral Therapy

technical field

The utility model relates to a suction tube for oral treatment, in particular to a multi-functional oral treatment which can be switched flexibly and can reach cavity, medullary cavity or root canal and the narrow operation and treatment area of oral cavity and maxillofacial area. Use a suction tube.

Background technique

In clinical oral cavity, some narrow fine parts are often treated, such as root canal treatment (including conventional and microscopic, ultrasonic root canal therapy, etc.), tooth defect treatment and surgical treatment of various fine parts in the oral cavity. In the above-mentioned treatments, there is a large amount of liquid in the operation area (including cooling water, blood, purulent exudate, root canal irrigation and disinfection solution, etc.) almost throughout the treatment process. In a small oral environment with limited light, The existence of liquid makes the vision more blurred. If it is not cleaned up in time, effectively and quickly, it will directly affect the accuracy of treatment and will greatly prolong the chairside operation time of doctors and patients. Especially in the process of root canal treatment, it is necessary to clean up the liquid, debris, tissue, etc. in the pulp cavity and root canal at any time, and it is necessary to observe the subtle changes in the pulp cavity and root canal with a better view. During tube therapy or other microscopic treatments, the operation is extremely delicate, complicated, and time-consuming, and the requirements for cleaning the liquid in the surgical area are higher. In addition, in the treatment of infected root canals, drainage of exudates from the root to the crown can reduce the pressure and stimulation on the root tip tissue and promote the shortening of the course of treatment.

In the prior art, degreased cotton or gauze are all used to clean up the operation area. For example, the liquid in the medullary cavity and root canal is torn by the doctor to remove the absorbent cotton, make a cotton ball or cotton twist to absorb the liquid, or extract a paper tip and put it into the root canal to absorb the liquid in the root canal. When drying the root canal, each root canal It needs to make 3-4 cotton twists, or extract 5-10 paper points to complete. If the root canal is thick or oozes out, it needs to be repeated more times. For the endodontic treatment of 2-5 root canals, it is necessary to repeatedly make cotton Balls, cotton twisting, and extraction of multiple paper tips are cumbersome operations, and often require each doctor to be equipped with a nurse to "operate with four hands" or even "operate with six hands" in order to improve treatment efficiency. Obviously, this operation mode of the prior art will prolong the treatment time and reduce the treatment efficiency. Moreover, the drying method has no obvious suction effect, and the effect of reducing pressure and drainage in the apical area is not obvious.

In order to improve the treatment efficiency, doctors use three-way air guns to blow away the liquid in the operation area in endodontic treatment to obtain a better view. Although part of the liquid can be quickly removed in this way, the mixed liquid of infectious substances in the medullary cavity will be diffused into the oral cavity under the action of the airflow, and the thrust of the large airflow in an instant will push the liquid and debris along the root canal to the root, which does not meet the requirements. The root canal treatment operation of the therapeutic principle, when operating under the microscope, will interrupt, hinder or even lose the best view.

Those skilled in the art have improved the above problems, and proposed to use the suction head of the oral aspirator to suck out the operation area, suck out the main liquid in the root canal by using negative pressure suction, and quickly clean up most of the liquid in the root canal in time, so that the operation Provide patients with a good vision in time, reduce the residue of infectious substances and liquid medicine, reduce debris blocking the root canal, help reduce the pressure on the apical area, and promote the exudate in the periapical tissue of the affected teeth to the root. Drainage in the tube improves the quality of treatment. There are mainly two kinds of negative pressure suction techniques used: the first one is to seal the root canal opening with rubber or other temporary sealing materials, and use a syringe to forcefully suck it back, and repeat it many times. It can achieve the effect of negative pressure, but the operation is complicated (the operator needs both hands to perform it). This method is also mainly used in the research stage, and the actual application is relatively small; the second method is to make a suction head, which is connected to a special oral cavity when used. On the negative pressure suction device, the root canal suction is performed. Every time it is used, the suction device that the patient sucks saliva must be taken out, and the root canal suction head is installed. When the patient needs to suck saliva, the root canal suction head must be removed. Time to reinstall. This operation is still cumbersome for the operator and assistants, and this suction device is made of stainless steel, which needs to be cleaned and sterilized, and the cost is high, so it is difficult for more medical institutions to purchase and use. In addition, the one-piece stainless steel tube is a rigid tube and cannot be bent at any angle. , it is more difficult to operate the posterior teeth in the oral cavity that are difficult to reach.

Therefore, how to solve the above-mentioned problems in the prior art has become a research hotspot for those skilled in the art.
