Description

Lower alveolar nerve anesthesia indicator Technical Field The utility model relates to the technical field of medical appliances, in particular to a lower alveolar nerve anesthesia indicator. Background When performing a third molar extraction of the mandible, the dentist often prefers local anesthesia. Local anesthesia is an anesthesia method in which local anesthetics are used to temporarily block sensory conduction functions of nerve endings and fibers in a certain region of the body, thereby temporarily eliminating pain sensation in the region. The lower alveolar nerve blocking anesthesia is the most commonly used local anesthesia method, which is a method for achieving an anesthetic effect by injecting local anesthetic into a nerve vicinity based on the running anatomy of each branch of the mandibular nerve based on the innervation of the mandibular nerve to the mandibular region. The mandibular tab is often considered an important marker for lower alveolar nerve blocking anesthesia, which is anesthetized when a anesthetic is injected in the vicinity. The existing anesthesia method mainly comprises two modes, namely an open-mouth injection method, wherein a medical staff refers to an intraoral mucosa sign according to experience to estimate the position of a mandibular small tongue for anesthesia, the primary anesthesia success rate is low for patients with limited open mouth, enlarged tongue body or tension and can not be matched, the effect is difficult to ensure, and the other method is a closed-mouth injection method, the needle insertion sign point is not clear, the needle is difficult to confirm to enter a target area, and the difficulty of taking out a separation instrument is extremely high if the needle is separated. There is a need to design a device for assisting in anesthetic injection. Disclosure of utility model The utility model aims to overcome the defects and shortcomings of the prior art and provides an indicator for the anesthesia of the lower alveolar nerve. In order to achieve the above purpose, the utility model adopts the following technical scheme: The lower alveolar nerve anesthesia indicator comprises a connecting rod, wherein a base station is fixed on the connecting rod, two sides of the connecting rod are connected with indication rods, the two indication rods are symmetrically arranged on two sides of the base station respectively, and an indicator connecting seat is fixed on the base station. Further, rod external threads are arranged at two ends of the connecting rod, directions of the two sections of rod external threads are opposite, first nuts are fixed on the indicating rods, and the first nuts are respectively connected to the two sections of rod external threads in a threaded mode. The indicator connecting seat is fixedly provided with a fixing rod, the fixing rod is fixedly provided with a second locating sleeve, the second locating sleeve is rotatably connected to the connecting rod, the middle of the connecting rod is provided with an optical axis section matched with an inner hole of the locating sleeve, the locating sleeve is sleeved on the optical axis section, two sections of the connecting rod are provided with limiting sleeves on two sides of the locating sleeve, and the two limiting sleeves are respectively attached to two sides of the locating sleeve. Further, the inner holes of the limiting sleeves are provided with inner threads, and the inner threads in the two limiting sleeves are respectively connected to the outer threads of the two sections of rods in a threaded manner. Further, an arc-shaped surface is arranged on the surface of the indicator connecting seat. Further, a handle is fixed at one end of the connecting rod, and a handle sleeve is sleeved outside the handle. After the structure is adopted, the dental mouth mirror has the beneficial effects that when the dental mouth mirror is used, the indicator connecting seat is connected and fixed with the dental mouth mirror handle, and the two indicator rods are respectively positioned at the highest point of the condyle and the lowest point of the mandibular angle notch, so that the indicator connecting seat is directly aligned and positioned with the horizontal plane of the mandibular tongue, and after the horizontal needle enters the front edge of the mandibular ascending branch from the horizontal plane, the area where the mandibular tongue is located can be reached along the inner side of the mandibular ascending branch by 1.5cm, and satisfactory anesthesia effect can be obtained by injecting the gunpowder.
