Description

Scald preventing wax dyke fixer special for repairing oral cavity

Technical Field

The application relates to an oral medical instrument technology, in particular to an anti-scald wax bank fixer special for repairing an oral cavity.

Background

In the process of repairing the oral cavity, a doctor needs to iron and roll the red wax sheet into strips to manufacture two wax dykes which are worn on the upper jaw and the lower jaw of a patient respectively to simulate the teeth of the upper jaw and the lower jaw of the patient. And the proper shape and position of the wax dyke are adjusted by adding and subtracting wax according to the anatomical structure and facial appearance of the temporomandibular joint of the patient. After proper adjustment, a doctor scalds the wax knife by using an alcohol lamp, scalds the junction of the upper wax bank and the lower wax bank in the mouth of a patient, and fixes the wax knife together after solidification. The doctor fixes the upper and lower jaw wax dykes and then takes out the upper and lower jaw wax dykes from the mouth of the patient. However, in the process of placing the wax knife into the mouth of a patient to fix the wax dike, the burnt wax knife is very easy to contact the fragile oral mucosa of the patient due to careless operation of a doctor or movement of the mouth and lips of the patient, and burn is caused.

The tissue around the oral mucosa has abundant blood circulation, loose tissue and serious edema after burn. The nerve distribution of the oral mucosa is rich, the pain is severe after burn, and the wound surface is stimulated by swelling and saliva, so that eating is often impossible. In addition, oral feeding can pollute the wound surface and influence the healing of the wound surface. In summary, burns can cause great pain to the patient.

Disclosure of Invention

The application aims to provide an anti-scalding wax bank fixer special for repairing an oral cavity, which can fix upper and lower jaw wax banks, is convenient for doctors to use, and can prevent the wax knife from contacting with an oral cavity membrane to prevent scalding.

The application is realized by the following technical scheme:

the anti-scalding wax bank fixer special for repairing the oral cavity comprises a shell with hollow inside and two open ends, wherein an angle drag hook is arranged outside the shell and connected with the shell; the piston is arranged in the shell, the piston can move in the shell along the axial direction of the shell, the heating head is fixed at the bottom of the piston and extends out of the shell, the outer wall of the heating head is sleeved with the elastic resetting device, and the elastic resetting device is arranged in the shell and located below the piston. At present, when an stomatologist performs an oral repair operation, red wax sheets are firstly scalded and soft rolled into strips to form two wax dykes, the two wax dykes are worn into the upper jaw and the lower jaw of a patient respectively to simulate the teeth of the upper jaw and the lower jaw of the patient, then the proper shape and position of the wax dykes are adjusted by adding wax and subtracting wax according to the anatomical structure and the facial appearance of the temporomandibular joint of the patient, after proper adjustment, the doctor scalds the wax knife by using an alcohol lamp, the juncture of the upper wax dykes and the lower wax dykes is scalded in the mouth of the patient, the juncture of the upper wax dykes and the lower wax dykes is fixed together after solidification, and the doctor integrally takes out the mouth of the patient after fixing the upper and lower jaw wax dykes. In the process of placing the wax knife into the mouth of a patient to fix the wax dyke, the risk that a doctor carelessly operates or the mouth and lips of the patient move to cause the scalded wax knife to contact the oral mucosa of the patient exists, the oral mucosa is very fragile, once the scalded wax knife contacts the oral mucosa, burn is caused, great pain is brought to the patient, meanwhile, the temperature change of the wax knife is fast, in order to maintain enough operation time, the wax knife needs to be heated to a higher temperature by an alcohol lamp, the temperature of the wax knife is higher, the wax dyke is excessively melted, the patient is scalded by the wax liquid flow or the wax smoke is generated, if the temperature of the wax knife is too low, the wax dyke is slow to melt or even not melt, the operation effect is influenced, the prior art or structure is not provided for solving the problems, the problem can only be avoided as much as possible through the experience of the doctor and the patient, the wax dyke fixer of this scheme is through holding patient's oral corner lip with the oral corner drag hook to gently push away, promote the heating head along the axis direction of shell with the piston and remove, with the contact of intraoral wax dyke, the wax dyke melts fixed back and removes the heater from patient's oral cavity angular direction to the centre under the effect of elastic reset device automatic reset, take off the heater, accomplish fixed process, the heater has replaced the heating of alcohol burner to the wax sword, its temperature control is at suitable invariable temperature, the temperature is unchangeable basically when the wax sword is used, can accurately find stable heating position when the doctor is used and then move and fix work, doctor's operation is more convenient accurate, can be controllable completely to the operating position, the heater can not contact with the oral mucosa completely, can not cause the scald to the patient.

In order to have enough length to push open the mouth angle, so set up the mouth angle drag hook and pull the lip for the patient can't the lip produce natural motion when the operation, can avoid scalding like this, the mouth angle drag hook is half moon shape with the mouth angle lip shape adaptation when people opens the mouth, and area of contact is bigger like this, prevents to skid, safer during the use. The connecting ring is sleeved on the outer wall of the shell, the connecting ring can move on the outer wall of the shell along the axial direction of the shell, an extension plate is arranged between the angle drag hook and the connecting ring, and the extension plate is connected with the outer wall of the connecting ring and the angle drag hook. Thus, the working range of the fixer can be enlarged in use along with the movement of the connecting ring on the outer wall of the shell along the axial direction of the shell and the length of the extension plate, so that the operation of doctors is convenient, and enough space is available for adjustment.

The piston comprises a piston rod and a piston head, the piston head is arranged in the shell, the outer wall of the piston head is sleeved with a rubber ring as a sealing ring and then is in seamless contact with the inner wall of the shell to form a seal, the bottom of the piston rod is inserted into the shell and is fixedly connected with the top of the piston head, the top of the piston rod is fixedly provided with a pressing disc, the size of the pressing disc is larger than the cross section of a cavity of the shell, the pressing disc is used as a stress point to push the piston rod and the piston to move during operation, and the pressing disc is always arranged outside the shell to play a limiting function. Meanwhile, the top end of the shell is outwards protruded to form an outer wing plate, the outer wing plate is of two semicircular structures, the outer wing plate is symmetrically arranged along the axis of the shell and connected into a whole, the outer wing plate is flush with the top end surface of the shell, and the outer wing plate is used as a stress point when an index finger and a middle finger are clamped during use and is contacted with the pressing plate after the pressing plate is pressed down, so that the clamping injury to the fingers is prevented.

In order to realize heating and temperature control and keep at constant temperature, a power supply and a circuit board which are connected with each other are arranged on the piston rod, the circuit board is connected with the heating head, a temperature indicator lamp and a switch are arranged on the shell, the temperature indicator lamp is connected with the heating head, and the switch is connected with a wire between the power supply and the circuit board. The circuit board is the existing structure, can purchase between market, is provided with heating circuit on it, has the constant temperature function that keeps simultaneously, utilizes the switch as the control unit of power circular telegram, and the temperature indicator lamp utilizes the colour to distinguish whether the heating head generates heat and at suitable temperature.
