Abstract
The utility model discloses an extractor for taking out a broken stainless steel device in a root canal. The extractor consists of a handle and a magnetic pin, wherein the rear end of the magnetic pin is connected with one end of the handle, the handle is straight or bent, and the magnetic pin is magnetic. The utility model aims to form a shape of a root canal prefabricated device or an ultrasonic working tip by utilizing a magnet material; and during application, the root canal above a broken device is prefabricated to be a large-taper straight circuit, the extractor is inserted into the upper section of the prefabricated root canal, and the broken stainless steel device in the root canal is extracted out by utilizing attraction force of the magnet material. The extractor for taking out the broken stainless steel device in the root canal, disclosed by the utility model, has the advantages of simple structure, convenience for use, capability of relatively easily taking out the broken device, time and labor conservation, and high success rate, and also has the advantages of improving the efficiency of taking out the broken device, reducing the working strength of doctors, rescuing teeth which are not rescued in the prior art, and can be popularized and applied clinically.
Description
Technical field
This utility model relates to a kind of extractor of stainless steel instruments of fractureing in the root pipe that is used to take out, and belongs to type medical instrument for dental use field, oral cavity.
Background technology
Root canal is to treat the effective method of dental pulp disease and periapical disease at present, and its theoretical basis is through thorough debridement, and residual dental pulp and catabolite, microorganism and the toxic metabolite of removing pathological changes in the root pipe also enlarge shaping root pipe; Through intracanal medicament sterilization control infection, it is minimum that the amount of microorganism in the root pipe is dropped to, and makes the root pipe be in aseptic relatively state; Use the good filler of closure with root-canal filling, thoroughly seal apical foramen of tooth to reach generation that prevents periapical disease and the purpose that promotes the periapical lesion healing.The root canal technology has developed into a whole set of the complete theoretical system that comprises rich content, enriches theory and accurate operation technology.Its therapeutic process comprises root canal preparation, root canal disinfection and root-canal filling.Wherein the quality of root canal preparation is the key factor of decision root canal success or not.The anatomic characteristic of root canal system directly affects the process and the effect of root canal preparation.Relatively easy, the safety of the root canal preparation process of taproot pipe and light moderate crooked root tube; Yet then difficulty is big for severe crooked root tube or its preparation process of calcification root pipe, and the instrument fracture of generation and isolating danger are arranged.In case this thing happens to root canal then cause very big difficulty.Handle this type case at present and at first will the apparatus among the Yu Genguan that fracture be taken out, and then carry out perfect root canal.The taking-up of apparatus of fractureing at present adopts small size root canal file around the apparatus that fractures, to prepare the gap with the free apparatus that fractures, and utilizes the vibrations of ultrasonic instrument in the root pipe apparatus that will fracture to take out of then.The taking-up of apparatus of fractureing is a job very consuming time, and success rate is not high, has the danger that the root canal wall side is worn takes place.
Summary of the invention
To above-mentioned prior art, this utility model provides a kind of extractor of stainless steel instruments of fractureing in the root pipe that is used to take out, and it can relatively easily take out the apparatus that fractures, and is time saving and energy saving, and success rate is high.
This utility model is realized through following technical scheme:
A kind ofly be used to take out the extractor of stainless steel instruments of fractureing in the root pipe, be made up of handle and magnetic pin, the rear end of magnetic pin is connected on the end of handle, and handle is linear type or flexure type, and the magnetic pin is the pin that has magnetic.
Said magnetic pin can be that ferromagnetic material is processed, and such as ndfeb magnet, takes out to guarantee the stainless steel instruments that its magnetic force enough will fracture in the Yu Genguan.
The basic thought of this patent is to utilize ferromagnetic material to be made into the shape of root canal preparation apparatus or ultrasonic tip; During application; The root canal preparation of the apparatus top that fractures is become the linear passages of big tapering; Then the apparatus of this utility model is got into ready pipe epimere, utilize the captivation of Magnet will be positioned at the stainless steel instruments sucking-off that fractures of root pipe.
This utility model is to be used to take out the extractor that splits off stainless steel instruments in the Yu Genguan, and is simple in structure, easy to use; Can relatively easily take out the apparatus that fractures, time saving and energy saving, success rate is high; Improved the efficient that the apparatus that fractures takes out; Alleviated doctor's working strength, saved the tooth that in the past can not exist, the suggestion clinical application.
Description of drawings
Fig. 1 is the structural representation of this utility model.
Wherein, 1, handle; 2, magnetic pin.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described.
A kind ofly be used to take out the extractor that splits off the stainless steel instruments in the Yu Genguan, be made up of handle 1 and magnetic pin 2, as shown in Figure 1, the rear end of magnetic pin 2 is connected on the end of handle 1, and handle 1 be a flexure type, and magnetic pin 2 is the pin that has magnetic.
Said magnetic pin 2 is processed by the ferromagnetic material ndfeb magnet, to guarantee that its magnetic force is enough big and stainless sodium apparatus in the Yu Genguan that will fracture takes out.
During application, the root canal preparation of the apparatus top of fractureing is become the linear passages of big tapering, the apparatus with this utility model gets into ready pipe epimere then, the rustless steel that utilizes the captivation of Magnet will be positioned at the root pipe apparatus sucking-off that fractures.
This utility model is to be used to take out the extractor that splits off the stainless steel instruments in the Yu Genguan, and is simple in structure, easy to use; Can relatively easily take out the rustless steel apparatus that fractures, time saving and energy saving, success rate is high; Improved the efficient that the apparatus that fractures takes out; Alleviated doctor's working strength, saved the tooth that in the past can not exist, the suggestion clinical application.
