Abstract
The utility model relates to the technical field of medical equipment, particularly an electrothermal gutta percha cutting device. The purpose of the utility model is to provide the electrothermal gutta percha cutting device which can solve the problems existing in the prior art that the operation is trouble; the unsafe factors are more; the environmental influence is big; the operation difficulty and patient psychic burden can be increased. In order to overcome the problems existing in the prior art, the utility model is characterized in that the electrothermal gutta percha cutting device comprises a handle and a cutting head, wherein the cutting head is fixedly connected with the handle; the handle is made from insulating material; the cutting head is made from electrothermal material; the cutting head is connected with a power supply conducting wire which is arranged in the handle.
Description
Affiliated technical field:
This utility model relates to technical field of medical instruments, is specifically related to a kind of electric heating gutta-percha cutter sweep.
Background technology:
Root canal therapy is one of the most frequently used method of tooth body pulpal treatment.In this process, its step comprises root canal preparation, sterilization and filling step.Usually use gutta-percha to fill in the filling step in the root pipe, after filling, need carry out the finishing of shape, the thermal cutting method of at present common usefulness is carried out during finishing, promptly cuts finishing with alcohol burner heating excavator spoon.Because used device brings inconvenience many in the clinical manipulation:
(1) troublesome poeration: owing to heat with alcohol burner, the bad grasp of the temperature of excavator spoon can be taken out of by the gutta percha point that filling is good when the excavator spoon heating-up temperature is not enough, causes and does over again; Excavator spoon leaves thermal source and promptly begins cooling, needs repeatedly heat repeatedly excavator spoon in the process of cutting several gutta-perchas continuously.
(2) unsafe factor is more: the excavator spoon temperature of heating is very high, in clinical manipulation as accidentally can cause patient's mucosa to scald; Clinical position is busy, and alcohol burner has the possibility that is knocked over, and ethanol is inflammable, has certain risk factor.
(3) big, increase operation easier affected by environment: ventilations such as electric fan, window make that the flame of alcohol burner is fluid, usually will block wind direction so that flame stabilization carries out the excavator spoon heating with hands or article in the work.
(4) increase the patients ' psychological burden: need use a lot of metallic weapons during the oral pathology treatment, the piping that sends when high-speed air turbine rotates in addition, make a lot of patients produce anxiety and the psychology of fear, and used alcohol burner heat the easier patients ' psychological burden that increases the weight of of apparatus in this cutting.
Summary of the invention:
The purpose of utility model is that the cutter sweep of the gutta-percha in a kind of root canal will be provided, with overcome troublesome poeration, unsafe factor that prior art exists more, affected by environment big, increase operation easier and increase the problem of patients ' psychological burden.
For overcoming the problem that prior art exists, solution of the present utility model is: the gutta-percha cutter sweep in a kind of root canal, comprise handle 2 and cutting head 6, cutting head 6 is fixedly linked on the handle 2, its special character is, described handle 2 is made for insulant, and described cutting head 6 is a thermo electric material, and it is connected with the power lead 4 of setting in the handle 2.
Above-mentioned thermo electric material can be chromed tungsten filament.So long as the energising after can heat rapidly and be heated the back on-deformable metal material all can select for use.
Such scheme also comprises optical fibers 3, and the termination of described optical fibers 3 is arranged at the top of cutter 6.
End near handle 2 on the above-mentioned cutting head 6 is provided with thermal sleeve 5, and described optical fibers 3 is arranged in the thermal sleeve 5.
Compared with prior art, the utility model has the advantages that:
This utility model utilizes strong point point discharge principle to heat cutter, and the cutter temperature is continual and steady, has simplified operation sequence, and no unsafe factor, and not affected by environment can alleviate patient's psychological burden in this link; Increased simultaneously optical fibers on this product, as lighting source, volume is little, has increased operating reliability with the luminous point of its termination.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Description of reference numerals is as follows:
1--rechargeable battery, 2---handle, 3---optical fibers, 4---power lead, 5---thermal sleeve, 6---cutting head.
The specific embodiment:
Referring to Fig. 1 and Fig. 2, this utility model comprises handle 2, thermal sleeve 5 and cutting head 6, and cutting head 6 is fixedly linked on the handle 2, and the end near handle 2 on cutting head 6 is provided with thermal sleeve 5, and thermal sleeve 5 is wrapped in cutting head 6 outsides.Said handle 2 is made for insulant, and cutting head 6 is made for thermo electric material, and what said thermo electric material was selected for use in the present embodiment is the chromium plating tungsten filament, and it is connected with the power lead 4 of setting in the handle.This product also comprises the optical fibers 3 that is connected on the power supply, and said optical fibers 3 is arranged in the thermal sleeve 5, and its termination is arranged at the top of cutter working end.Because cutter will contact human body, must guarantee operator and patient's safety, therefore be provided with rechargeable battery 1 as power supply in the handle 2 of this product, carry out dc low-voltage heating (voltage is 3V), for the convenience of the users, handle 2 is provided with the button type switch, power lead 4 that this switch Synchronization Control links to each other with cutter and optical fibers 3.Rechargeable battery 1 can be by charging with the charger of 220V alternating current as power supply.
Using method: energized, handle 2 inserts on the charger, treats can pull up use behind the full charge.Open the switch on the handle 2, it is temperature required that cutting head 6 can reach the cutting gutta-percha second at 1-2, meanwhile the luminous light source that provides in the termination of optical fibers 3.End of operation closes swap switch, and it is stand-by that handle 2 inserts charger again.
