Description

Operating microscope

Technical Field

The utility model relates to a technical field is diagnose to the dentistry, especially relates to an operation microscope.

Background

The operation microscope can be used for examination and treatment of dental pulp and root canal, and can clearly observe the position of root canal orifice, the inner wall form of root canal, and the tooth pulp removing condition in root canal, and can prepare and fill root canal, take out broken apparatus in root canal, and perform periapical operation. By means of sufficient illumination and clear amplification observation, the popularization of the oral operation microscope changes the traditional extensive operation based on experience and handfeel, and the treatment success rate of root canal treatment, taking out of metal blockages in the root canal, root canal steps, root apex deviation and medullary cavity perforation is greatly improved.

On the other hand, the body position of the patient must be transferred, so that the doctor cannot keep a normal and comfortable posture, the shoulder, neck and back muscles are fatigued and sore due to continuous fine operation, serious joint problems can be caused after long-term accumulation, and the occupational life of the doctor is even affected. The appearance of the operating microscope solves the problems, and the operating microscope can ensure that a doctor keeps a correct posture according with human engineering in the checking and treating processes, eliminate the fatigue of shoulders, necks and backs, and effectively improve the diagnosis and treatment efficiency and quality.

However, the conventional surgical microscope can only observe the structure of the outer layer of the tissue, cannot observe the structure of the internal tissue, and is long in time and easy to miss root canals or excessively remove healthy tooth tissues due to repeated probing in some operations. The teeth are in a three-dimensional structure and are in multi-level tissues, and an operation microscope can only observe detailed characteristics of the outer layer of the tissues and cannot judge the structure of the inner layer of the tissues.

The portion of the cavity in the middle of the tooth contains soft tissue known as the pulp. The upper part of the cavity is wide, called the pulp chamber, and the lower part is provided with a tubular root canal from which the blood vessels of the dental nerve and the trophic nerve are derived. Infections occur in the pulp of the teeth, causing pain, jaw infections, and eventually the teeth become weakened due to death of the dental nerves.

In the case of root canal treatment, the physician needs to open the pulp cavity completely, find all the root canals and treat them. Humans typically have 1-4 root canals per tooth, with the most root canals in the posterior teeth. When the root canal orifice is difficult to find due to the conditions of age-increasing change, deposition of restorative dentin, pulp stones, pulp cavity calcification, root canal morphological variation and the like, the anatomical morphology of the pulp cavity needs to be understood and seen from all directions and positions by virtue of the three-dimensional anatomical morphology of the tooth; the number, shape, position, direction and bending condition of the tooth root and the root canal are known and indicated by adopting X-ray films shot by a plurality of angle projection methods; the relationship of the tooth root to the crown; various possible variations of anatomical morphology of the root canal and root canal, etc. As the number of the root canals of part of teeth can reach four, complicated conditions such as collateral root canals, apical bifurcation and the like can exist, and omission can be caused even under the condition of magnifying observation; it is desirable to estimate the likely location of the root canal, and if necessary, to remove a small amount of dentin using a button drill in the sulcus where the root canal is likely or expected, and then to use a sharp probe to attempt to penetrate any calcified areas to indicate where the canal orifice removes the dentinal collar of the neck of the tooth to expose the canal orifice, i.e., if there is a calcification of the canal orifice, it is even more desirable for the practitioner to make repeated trials at each possible location, and inevitably remove too much healthy tooth tissue.

At present, a preoperative dental film mode is often adopted to help a doctor judge and determine the number and the form of root canals, firstly, the doctor needs to divide partial energy to remember the form of a root cap, and even the doctor pauses the operation to observe the dental film again. In addition, the dental film is only a two-dimensional plane image, so that the three-dimensional shape of the root canal cannot be accurately reflected, and actually, the trend of a plurality of root canals is bent for many times, so that the dental film cannot be used for accurate positioning.

Stereo images such as CBCT are complex and difficult to memorize, doctors need to memorize the stereo morphology of the tooth structure in the brain and compare, superpose and fuse with the real object under the microscope in the operation, great efforts are needed, and the accuracy and precision are difficult to ensure.

Therefore, in combination with the above-mentioned technical problems, a new technical solution is needed.
