The present invention relates to a dental forceps structure, and more particularly to a dental forceps structure, having a simple structure and convenient operation, capable of effectively fixing the position of a water suction element, preventing tongue disturbance from interfering therapy, further improving the therapeutic efficiency of physicians, providing a clear vision of the physician, and protecting patients from medical accident.
Generally, dental physicians may use various different handheld devices to carry out oral examination or treatment of dental diseases for patients; the common handheld devices are high-speed handheld unit, forceps, mouth mirrors, probes, washing machines, etc., and general dental treatments includes dental filling, filling of the gap, root canal treatment, periodontal treatment, tooth extraction, etc. In the implementation of the preparation of a decayed tooth cavity and the preparation of a tooth gap, a dentist must use one hand to hold a mouth mirror to open a patient's cheek or tongue, and another hand to hold a high-speed handheld unit to remove the tooth decay area or clean the dirt in the gap with a drill needle configured on it. If the patient's tongue is easily disturbed, the mouth mirror should be used to suppress and protect the tongue to ensure that the high-speed turning needle does not harm the patient's tongue.
After the preparation of a decayed tooth cavity and the preparation of a tooth gap are completed, a general practice is that the dentist will insert a gauze or lap into the lingual and buccal side of the affected area to isolate the affected part, dry the affected part by blowing wind, and then use composite resin to fill the cavity or gap of the decayed tooth.
The above treatment has some trouble situations. One of the trouble situations is that the patient's tongue may involuntarily disturb to push the gauze or lap out of the lingual side, or the contraction of the cheek muscles will push the gauze or lap out of the buccal side, causing the insolated area to be destroyed to cause saliva to contaminate the treatment area such that the dentist must isolate the affect part again, which wastes time or influences the accuracy of the combination of the filling material with the tooth, causing the shedding or poor fit thereof.
Another common trouble situation is that patients who are prone to laryngeal vomiting and reflexes are common in young children and some adults; such kinds of patients always cannot be inserted with gauze of lap into the lingual side when the composite resin is filled in the cavity or gap because it is easy to induce vomiting and reflex in the throat, causing gauze or lap to fall into the patient's esophagus or trachea, causing serious medical accidents and medical disputes. Therefore, the affected parts cannot be surely isolated and dried, and therapeutic effects are reduced when the cavity filling with composite resin or gap for such kinds of patients is carried out.
It is also common to use a rubber dam that is commonly used in root canal treatment as a tool for the affected part isolation upon a cavity filling or gap filling. However, the above treatment cannot be routinely used due to complicated operations, time consuming, and high material cost and because it is easy to accidentally hurt the gums when the rubber dam is clamped on the teeth, causing pain and bleeding.
To overcome the above shortcomings and to develop a dental forceps structure, which is structurally simple and conveniently operative, can fix a water suction element effectively, accurately prevent the disturbance of a tongue from interfering therapy, provide a physician's clear operational vision, and have advantages such as patient protection and medical accident prevention, the present invention is proposed.
The main object of the present invention is in that: a lap clamp (accommodation elements) and tongue block (barriers) are in combination with the front end of forceps and placed on an affected area to block a patient's tongue involuntary disturbance with the barrier on the lingual side and stop the patient's buccal muscle contraction with the barrier on the buccal side, and a water suction element is accommodated and fixed between the accommodation elements, which can promote physicians' therapeutic efficiency, keep operation area dry, provide physicians with a clear operational vision, and more effective in preventing accidents in which the water suction element is accidentally swallowed by the patient or dropped into the trachea during the treatment.
Another object of the present invention is in that: the barrier on the buccal side can be used to open the cheek muscles before the water suction element is accommodated between the accommodation elements so as to form an isolation area during the dental treatment, and the lingual barrier is used to replace a traditional mouth mirror to ensure that a high-speed rotating drill needle will not hurt the patient's tongue.
To achieve the above objects, the present invention proposes a dental forceps structure, including: a fixture body, including an elastic connection portion, two elastic arms formed on two ends of the elastic connection portion, and two bended clamping portions each formed on one end of one of the elastic arms; two accommodation elements, each configured on one of the clamping portions; and two barriers, configured on the respective clamping portions and positioned between the accommodation elements and fixture body, and adapted to isolate the disturbance of surrounding tissues and organs.
In practical use, a user only needs to place a water suction element such as gauze or lap between the accommodation elements, and then uses the countervailing limits with a semi-cylindrical frame to fix the water suction element. Next, the elastic arms of the fixture body is manually pulled apart, and the clamping portions of the fixture body are placed on both sides of the affected part so as to contract the elastic arms inward with the elastic force of the elastic connection portion 11, allowing the clamping portions to be naturally fixed to the two sides of the affected part, thereby reducing the burden on the physician's operation and indeed positioning the water suction element, and the wetting condition of the water suction element can be observed through the hollow portion. At the same time, the barrier on the lingual side is used to prevent the disturbance of a tongue, and the outside barrier is used to open the cheek, allowing the user's operational vision to be more clear and broad, further improving the efficiency and completeness of physician's treatment, and keeping the operation area dry and effectively preventing the water suction element from being accidentally swallowed by the patient or dropped into the trachea during the treatment process.
With the above technology, the present invention can break through the problems caused by conventional dental forceps, which cannot fix gauze or lap accurately, cannot keep operation area dry, cannot accurately prevent a tongue from interfering the treatment or pushing devices, and cannot solve the problem of some adults' or children's throats being prone to vomiting and reflex in the process of dental treatment.
Referring to
The fixture body 1 includes an elastic connecting portion 11, two elastic arms 12 formed on the two ends of the elastic connecting portion 11 and two bended clamping portions 13 each formed on one end of one of the elastic arms 12.
The two accommodation elements 2 are configured on the respective clamping portions 13, each of them has a countervailing limit 21, and at least one hollow portion 22 is defined between the two countervailing limits 21.
The two barriers 31, 32 are configured on the two respective clamping portions 13 and positioned between the accommodation elements 2 and fixture body 1; they are adapted to isolate the disturbance of surrounding tissues and organs.
With the above description, the structure of the present invention can be well understood. According to the corresponding match of the components, the present invention is structurally simple and conveniently operative, can fix a water suction element effectively, accurately prevent the disturbance of a tongue from interfering therapy, provide a physician's clear operational vision, and have advantages such as patient protection and medical accident prevention. The detailed explanation will be given in the following.
