Technical Field

The invention relates to the technical field related to medical instruments, in particular to a special stomatoscope for stomatology department.

Background

The stomatoscope is one of the common appliances used in stomatology department, a stomatologist generally needs to use the stomatoscope when diagnosing and treating oral diseases for a patient, the examination visual field can be effectively increased by the light reflection principle of the lens when carrying out oral examination, and the patient can take corresponding treatment measures through the stomatoscope to the disease condition in the oral cavity of the patient. At present, when carrying out oral examination, the patient need open the oral cavity, and the oral cavity doctor need use the disinfection ruler to handle the oral cavity to obtain better inspection field of vision, can lead to the patient to expand the oral cavity for a long time and feel the uncomfortable of two jaws like this, and inspection efficiency is not high, consequently needs one kind to have and slows down patient's fatigue and observe the wide mouth mirror of field of vision.

Disclosure of Invention

Aiming at the technical problems, the invention provides the special stomatoscope for the department of stomatology, which can relieve the fatigue of patients and increase the oral cavity examination efficiency.

The technical scheme adopted by the invention is as follows: a special stomatoscope for stomatology comprises a threaded hollow cylinder, threads, a sliding cylinder, a spring sleeve column, a sliding cylinder push ring, a push ring connecting rod, an oral cavity up-and-down supporting swing rod, a rubber sleeve, a speculum, an oral cavity left-and-right supporting swing rod, a push ring compression spring, a speculum rod sliding block, a conversion operating head and a speculum rod ball head. The sight glass rod is positioned in the threaded hollow cylinder, one end of the sight glass rod is fixedly provided with a sight glass, the other end of the sight glass rod is fixedly provided with a conversion operating head, and the sight glass rod is provided with a sight glass rod ball head.

The hollow screw thread cylinder is hollow, threads are arranged on the outer circumference of the hollow screw thread cylinder, the sliding cylinder is connected with the hollow screw thread cylinder through the threads, the sliding cylinder push ring is in contact with one end of the sliding cylinder and is in sliding connection with the spring sleeve column, one end of the spring sleeve column is fixedly installed at one end of the hollow screw thread cylinder, the push ring compression spring is sleeved on the spring sleeve column, one end of the push ring compression spring is in contact with the hollow screw thread cylinder, and the other end of the push ring compression spring is in contact with the sliding cylinder push ring.

The two oral cavity up-and-down supporting swing rods are provided, one end of each oral cavity up-and-down supporting swing rod is rotatably connected with the threaded hollow cylinder, the other end of each oral cavity up-and-down supporting swing rod is wrapped with a rubber sleeve, one end of the push ring connecting rod is rotatably connected with the oral cavity up-and-down supporting swing rods, and the other end of the push ring connecting rod is rotatably connected with the push ring of the sliding cylinder; the oral cavity support swing arm about have two, the oral cavity supports the one end and the hollow section of thick bamboo swivelling joint of swing arm about, the other end that supports the swing arm about the oral cavity is logical groove, the one end and the sliding barrel of throw-away ring connecting rod swivel connection, the other end and the oral cavity support swing arm swivelling joint about the other end of throw-away ring connecting rod.

The sight glass rod sliding block is slidably arranged in the threaded hollow cylinder, and the sight glass rod sliding block are connected through a sight glass rod ball head.

Compared with the prior art, the invention has the beneficial effects that: (1) the sight glass can move in multiple degrees of freedom, and the observation visual field is wide; (2) the sight glass is simply controlled by using the ball head for connection; (3) the use of the support rod can relieve the fatigue of the two jaws of the patient.
