Abstract
The utility model relates to a remove device in the root canal broken needle, including screw nut and miniature rank exit tube, the coaxial system of lower extreme of miniature rank exit tube has the hand -screw nut, and the trident centre gripping lamella of dividing equally is made to the upper end tip of miniature rank exit tube, and the outer fringe system of being close to the hand -screw nut in miniature rank exit tube lower part has the external screw thread, and lower part system has the internal thread in the screw nut, and the coaxial suit of screw nut is in miniature rank exit tube outer fringe to through screw thread activity meshing. The application provides a micro - supersound technical process of root canal broken needle remove device cooperation exceeds the broken needle of apical foramen of tooth, can suitably remedy micro - ultraaudible shortcoming, and the sleeve pipe only need expose broken needle hat end 13, the broken needle under curved curved attitude also available broken needle remove device entangle, avoided ultraaudible excessive deepening, prevent effectively that the side from wearing, also reduce the excessive contact of supersound apparatus and broken needle simultaneously, prevent the rupture of apparatus secondary.
Description
Technical field
This utility model belongs to Special medical equipment field, oral cavity, relates to broken needle withdrawing device in a kind of root pipe particularly.
Background technology
Instrument fracture is the common complication of root canal, and wherein consequence is the most serious, and treating the most difficult is that the apparatus that fractures exceeds apical foramen of tooth.Can not take out after broken needle or not by the bypass of root pipe to remove the consequence of pulp tissue and necrotic debris, be easily cause iatrogenic periapical periodontitis, the broken needle therefore in root pipe should take out as far as possible, and that can not take out will by root pipe bypass completed treatment.
Although the micro-ultrasonic superiority getting broken needle is unquestionable, its limitation is also very obvious.Due to the many narrow curved of root pipe hypomere, as broken needle is stuck in crooked root tube hypomere, the broken ends of fractured bone only just can be made to depart from curved side root canal wall and loosen when removing case of bending.But therefore can because removing too much curved side root canal wall dentin very easily side wear; Microscope limits because of the depth of field, the visual field is poor, tip of a root place does not have enough dentin thickness, very difficult foundation linear passages safely and effectively, adopt the ultrasonic higher-order of oscillation, be difficult to the broken needle shaking pine or shake the case of bending blocked by root pipe or apical foramen of tooth, because fractureing, tool temperature rising easily causes secondary breakdown.
According to the retrieval, find following relevant to the application patent, concrete disclosure is as follows:
Patent documentation CN204562445U discloses in a kind of root pipe and gets broken needle device, comprises plumb joint, union joint and operating grip, and plumb joint is fixed by the front end of union joint and operating grip, and operating grip rear end is fixed by connecting line and heating power supply; Heating rod is provided with in described operating grip, heating rod is connected with connecting line, heat conduction axle is provided with in described union joint, heat conduction axle is connected with heating rod, described plumb joint front end is stretched out and is provided with metal tip, attached low melting point scolding tin is melted at the tip place of metal tip, and metal tip and heat conduction are coupling to touch and are connected.
Patent documentation CN203915120U discloses a kind of root pipe broken needle suction means, comprise solenoid, described solenoid inside is hollow and two ends are respectively arranged with train head lid and afterbody end cap, described solenoid inner chamber is provided with hollow core, described hollow core is arranged with lead loop, and described solenoid train head lid center is also provided with probe.
Patent documentation CN102551847A discloses a kind of oral root canal broken needle magnetic pickup instrument and it is characterized in that utilizing magnetic force to form pull strength to broken needle in root pipe, broken needle is drawn out from root canal orifice, the present invention is mainly divided into two parts: a part is the magnetic portion head of traction root pipe broken needle, the magnetic magnetic needle of various band can be installed above, magnetic needle is stretched into tooth root mouth of pipe inside to contact with broken needle in root pipe, another portion is the body of transporting magnetic, it is by the manufacture of electric energy conversion magnetic energy out, magnetic energy can be transmitted, and have gauge tap, can increase or reduce magnetic force, if when broken needle resistance is little, if broken needle resistance can adopt greatly body to increase magnetic force and be pulled out by broken needle.
Said apparatus provides the scheme of taking out for broken needle in root pipe from different aspect, respectively have advantage, but the scheme that its improvement in broken needle clamping provides not as good as the application is better, and therefore the application compared with prior art has superiority.
Utility model content
The purpose of this utility model is to overcome technical problem, provides broken needle withdrawing device in a kind of root pipe.
The content of technical scheme to be solved in the utility model is as follows:
Withdrawing device in a kind of root pipe broken needle, comprise screw nut and miniaturely hold in the mouth pipe, miniature lower end of holding in the mouth pipe is coaxially integrally shaped with hand rotary nut, the trident clamping lobe divided equally is made in miniature end, upper end of holding in the mouth pipe, hold in the mouth pipe bottom near the outer rim of hand rotary nut be shaped with external screw thread miniature, in screw nut, bottom is shaped with female thread, and screw nut coaxial package holds in the mouth pipe outer rim miniature, and by screw thread activity engagement.
And when the length of described screw nut upper end is upwards revolved most with screw thread, screw nut upper end and trident clamp lobe upper end and flush, when screw thread is most to backspin, trident clamping lobe all exposes.
The beneficial effects of the utility model are:
The root pipe broken needle withdrawing device that the application provides coordinates micro-ultrasonic technique process to exceed the broken needle of apical foramen of tooth, suitably can make up micro-ultrasonic shortcoming, sleeve pipe only need expose broken needle hat end 1/3, broken needle also can entangle with broken needle withdrawing device in the bent state, avoid ultrasonic excessively going deep into, effectively prevent side from wearing, also reduce the excessive contact of ultrasonic instrument and broken needle simultaneously, prevent apparatus secondary from fractureing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model (partly cuing open);
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
Withdrawing device in a kind of root pipe broken needle, comprise screw nut 2 and miniaturely hold in the mouth pipe 3, miniature lower end of holding in the mouth pipe is coaxially integrally shaped with hand rotary nut 5, the trident clamping lobe 1 divided equally is made in miniature end, upper end of holding in the mouth pipe, for clamping broken needle, hold in the mouth pipe bottom near the outer rim of hand rotary nut be shaped with external screw thread 4 miniature, in screw nut, bottom is shaped with female thread, screw nut coaxial package holds in the mouth pipe outer rim miniature, and by screw thread activity engagement, when the length of screw nut upper end is upwards revolved most with screw thread, screw nut upper end and trident clamp lobe upper end and flush, when screw thread is most to backspin, trident clamping lobe all exposes.
Recommended size of the present utility model is: screw nut is diameter 0.5mm stainless steel silk.Miniature to hold in the mouth pipe be diameter 0.45mm stainless steel tube, and working end is the long trident clamping lobe of 5mm.
