Description

Benign Paroxysmal Positional Vertigo of Posterior Semicircular Canal Manual Reset Indicator

technical field

The utility model relates to a medical instrument, in particular to a manipulation reset indicator for posterior semicircular canal benign paroxysmal positional vertigo.

Background technique

Benign positional paroxysmal vertigo (BPPV) is a short-term vertigo induced by head movement to a specific position. It is a self-limiting peripheral vestibular disease and is one of the most common diseases that cause vertigo. one. Among them, posterior semicircular canal benign paroxysmal positional vertigo (posteriorsemicircularcanal BPPV, PC-BPPV) is the most common (80%-90%). Its pathogenesis is mainly semicircular canal stone theory (ie, tube stone theory). The denatured canal stone particles do not adhere to the ampulla ridge of the semicircular canal, but are free in the endolymph of the semicircular canal. When the head is in the induced position, the canal stone moves in the direction of gravity, causing the endolymph to flow, thereby pulling the ampulla ridge The deviation produces symptoms such as vertigo and nystagmus.

Before the invention of the utility model, the Epley method (also known as the tube stone reset method) was based on the above-mentioned theory. Through the directional head position movement, the tube stone returned to the utricle from the total foot and no longer affected the dynamics of the semicircular canal. The most commonly used method for benign paroxysmal positional vertigo of the posterior semicircular canal is recommended as the first-line therapy for benign paroxysmal positional vertigo of the posterior semicircular canal. Significantly shorten the time required for symptom relief, enable patients to return to social labor in time, and improve the quality of life. However, the technique and sense of rhythm of Epley manipulation for the treatment of benign paroxysmal positional vertigo of the posterior semicircular canal are very important. The time for stone position change allows it to return to the utricle under external stimulation, thereby eliminating clinical symptoms. Therefore, not all hospitals and doctors are able to master the skill of manual reduction well. If the operation is not performed properly, it may lead to poor improvement or even aggravation of symptoms such as dizziness, nausea and vomiting in patients after manual reduction. Doctors are not sure whether to use management The stone returns to the utricle, and it causes the patient's fear, anxiety, depression and other bad emotions, and the doctor-patient trust level is reduced.

Utility model content

The names of the components corresponding to the symbols in the figure are as follows:

Posterior semicircular canal 1, fluorescent tube stone 2, outer semicircular canal 3, superior semicircular canal 4, utricle 5, fixation band 6.

detailed description

As shown in Figure 1:

The posterior semicircular canal 1 is connected and communicated with the utricle 5, the outer semicircular canal 3 and superior semicircular canal 4 are connected but not communicated with the utricle 5, and the above structures together constitute the main lumen; the rolling range of the fluorescent tube stone 2 is between the posterior semicircular canal 1 and the utricle 5 Inside, that is, the fluorescent tube stone 2 can roll in the posterior semicircular canal 1 and the utricle 5. The posterior semicircular canal 1 and the utricle 5 are made of transparent material; Connected with 6; the fluorescent tube stone 2 is made by adding red fluorescent additives to transparent plastic particles; the posterior semicircular canal 1, outer semicircular canal 3 and upper semicircular canal 4 are also called posterior (vertical) semicircular canal and outer (horizontal) semicircular canal respectively , Anterior (vertical) semicircular canals, all of which are arcuate in shape and form an angle of 90 degrees with each other.

The posterior semicircular canal 1, the outer semicircular canal 3, the superior semicircular canal 4 and the utricle 5 are all made of transparent polymethyl methacrylate material (acrylic).

Description of the utility model application process:

In the process of treating benign paroxysmal positional vertigo of the posterior semicircular canal with Epley manipulation reduction, the fixation belt 6 is properly fixed on the patient's head first, and then the following steps are followed: A——The patient sits on the treatment bed, and the therapist quickly places it on the patient's head. Lay down to the supine position, extend the head out of the bed, and turn 45 degrees to the affected side; B——turn the patient’s head to the normal side gradually, and continue to turn to the healthy side 45 degrees; C—turn the patient’s head together with the body to the healthy side, Lie on your side on the treatment bed, keep your head at 135 degrees away from the supine position; D—return to the sitting position, and tilt your head forward at 30 degrees.

During this treatment, it can be seen that the fluorescent ductolith 2 gradually slides from the posterior semicircular canal 1 to the utricle 5, which proves that the real ductolith floating in the lymph fluid in the posterior semicircular canal returns to the utricle in the human body, thus resetting successfully .

In the application of the utility model to reset by Epley's technique, the posterior semicircular canal 1, the outer semicircular canal 3 and the upper semicircular canal 4 are all arcuate curved tube rings, and they form an included angle of 90 degrees with each other, perfectly simulating the posterior semicircular canal and the outer semicircular canal in the inner ear of the human body And the appearance and angle of the upper semicircular canal; at the same time, the posterior semicircular canal 1 communicates with the utricle 5, so that the fluorescent tube stone 2 can only roll from the posterior semicircular canal 1 to the utricle 5, perfectly simulating the position change of the real canal stone in the human inner ear.

The main lumens on the left and right sides are connected by a fixing belt 6, which is adjusted and fixed on the head according to the head shape of different patients. The position change of the tube stone 2, and vice versa, for patients with benign paroxysmal positional vertigo in the posterior semicircular canal of the right ear, observe the position change of the fluorescent tube stone 2 in the right main lumen. In the process of Epley manipulative reset and head position changes, the bilateral posterior semicircular canal 1, external semicircular canal 3, superior semicircular canal 4 and utricle 5 are always consistent with the real structural position of the human inner ear. Such a new application makes it unnecessary for the doctor to think about the position change of the real canal stone in the human inner ear during the Epley maneuver reset process, as long as the above reset steps are followed, pay attention to the position change of the fluorescent canal stone 2 in the transparent posterior semicircular canal 1, and finally reach the transparent utricle 5, the reset is successful. If the reset fails once, repeat the above steps. Even patients and family members who do not have relevant professional medical background can achieve good therapeutic effect as long as they operate strictly according to the instructions of the utility model at home.

Although the utility model has been described in detail above, the utility model is not limited thereto, and those skilled in the art can make various modifications according to the principles of the utility model. Therefore, all modifications made according to the principle of the utility model should be understood as falling into the protection scope of the utility model.
