Description
Technical Field
The utility model relates to the technical field of medical appliances, in particular to an auxiliary fixed oral appliance with a valve fixing ring.
Background
In recent years, a preparation device for a root canal has been greatly developed, and preparation devices of various materials and various designs are continuously developed. However, the research and improvement of the root canal file by the former scholars are relatively concentrated on the selection and innovation of the materials at the working end of the root canal file, the research of improving the auxiliary appliance of the application diameter of the root canal file is slightly insufficient, and certain defects exist in the research and breakthrough of the clamping mode of the root canal file, and the method is generally limited to one of the functions of falling prevention, detachability, direction adjustment and the like, so that the method cannot simultaneously meet the application requirements of the root canal file in multiple aspects in clinical treatment; secondly, many innovative designs clinically at home and abroad are in the two difficulties of coexistence of advantages and disadvantages at present: the mechanical file is used as one of research hotspots, and has unique advantages in root canal preparation, but has the defects of easy occurrence of instrument separation and lower safety; although the ultrasonic root canal device has good root canal cleaning effect, the ultrasonic root canal device is expensive, and the phenomena of poor root canal forming effect, root canal straightening and root tip deviation often occur when the root canal is bent. Various non-negligible disadvantages make the novel use of root canal files not further improved so as not to be widely used in clinic.
Endodontic surgery is currently the first method of treatment for dental pulp disease and periodontitis, and high quality root canal preparation and filling are key to the success of this procedure. Root canal preparation by using root canal file and other instruments, thoroughly eliminates the infection source in the root canal and creates good root canal passage and shape for root canal filling. Therefore, the physical and chemical properties and design characteristics of the root canal file and the auxiliary fixed oral appliance play a vital role in root canal treatment.
The shape of the root canal is mostly curved to present a certain radian, wherein the number of tooth roots of molar teeth is large, the shape of the root canal is complex, the running direction is curved narrowly, the preparation of the root canal of molar teeth is a difficult point and an important point in the whole mouth, and the performance requirement on the root canal preparation instrument is high. From clinical practice, we find that physicians have a great operational hurdle when performing posterior root canal dredging, which is particularly evident in patients with difficult coordination (e.g. children), with limited opening (e.g. various temporomandibular joint diseases, habitual joint dislocation patients). Because the too narrow intraoral operation space is difficult to expose the treatment field of view, and a doctor is difficult to stretch hands into the oral cavity of a patient, the use of the hand root canal file is limited, so that the clinical operation difficulty of the doctor and the discomfort of both doctors and patients are increased, the clinical treatment time is prolonged, and the treatment experience of the patient is influenced.
A Chinese patent (patent application number: CN 217938406U) discloses a hand-operated root canal file holder, wherein a root canal file is held by tooth-shaped petals of a rubber four-petal tooth-shaped retention device, the principle is that the root canal file is held by friction force between the tooth-shaped petals and the root canal file, but the risk of the root canal file being separated due to insufficient friction force still exists. Therefore, aiming at the application requirement of the root canal file and the defects and shortcomings of the oral appliance for assisting in fixing the root canal file at present, a novel improved appliance is needed in clinic, so that the technical problems are solved effectively.
Disclosure of Invention
Based on this, there is a need for an improved auxiliary fixation oral appliance for clamping root canal files in the prior art to increase the stability thereof.
The technical scheme is as follows: an auxiliary fixed oral appliance with a valve fixing ring comprises a handle end, a streamline bending connecting end and a clamping end, wherein the streamline bending connecting end is respectively connected with the handle end and the clamping end.
Preferably, the clamping end comprises a clamping outer sleeve and a valve fixing ring, wherein the outer ring of the valve fixing ring is fixed on the inner side of the clamping outer sleeve, and the inner ring of the valve fixing ring is provided with at least two retention petals which are annularly arranged.
Preferably, the cross section of the retention valve is in a slope-like structure, and a plurality of retention valves are annularly arranged on the inner ring to form an inverted concave structure similar to the shape of a heart valve. The retention flap is made of silica gel or rubber.
The key innovation structure of the technical scheme is that the retention valve on the inner ring of the valve fixing ring is in a slope-like structure, and a plurality of retention valves are annularly arranged on the inner ring to form an inverted concave structure of the heart valve. The root canal file mainly comprises a fixed end and a needle end, when the needle end of the root canal file enters the valve fixing ring from the concave surfaces formed by the plurality of fixing petals until the fixed end of the root canal file is contacted with the fixing petals, the contact part of the fixed end of the root canal file and the fixing petals can generate some friction force, and certain resistance is provided for the fixed end of the root canal file, but the resistance is not very large, so that the root canal file can be ensured to be stably clamped on the fixing petals under the condition of no external force. When the root canal file is used for working, the needle end of the root canal file can be pushed to the fixed end by reverse force, and at the moment, the fixed end of the root canal file can be subjected to the force of mutual extrusion between the retention petals except the friction force from the retention petals, so that the root canal file can be firmly clamped on the retention petals, and the stability of the auxiliary fixed oral appliance is improved.
