Abstract
The invention relates to a medical apparatus for dental surgery, and more specifically to a fang removing device, comprising a helical auger with its lower end provided with tapping screws and its upper end provided with a connecting screw rod. The helical auger is characterized in that: a nut to the helical auger is screw threaded on the upper part of the connecting screw rod; the middle part of an elastic rod is provided with a long-strip-like major through hole and the helical auger is installed through the hole. The fang moving device in the invention has a simple construction, is convenient for use, can remove fangs fast at a time, leaves a small wound in operation, and enables patients to suffer little pain.
Description
Technical field
The present invention relates to the medical apparatus and instruments that a kind of dental operation is used, is a kind of root of the tooth plucking device specifically.
Background technology
Tooth is subjected to being easy to fracture in wound or the extraction, and in principle, various being completely cured all should once be taken out when extraction.The pulling out of root of the tooth that fracture is comparatively complicated, and up to now, clinical method commonly used mainly contains the root pincers and pulls out method, dental elevator and get Gen Fa and turn over bone three kinds of methods of lobe.Often wound is big, operating time is long to use traditional method and apparatus to handle radix dentalis residualis, and causes the appearance of postoperative related complication in the art easily, and effect is undesirable, brings unnecessary misery to patient.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to use, can the residual root of the tooth of complete taking-up, root of the tooth plucking device that surgical wound is little.
For reaching above purpose, the technical solution adopted in the present invention is: this root of the tooth plucking device, comprise threaded bore, the lower end of described threaded bore is provided with tapping screw thread, the upper end of threaded bore is provided with connecting screw rod, be set with the threaded bore nut by threaded engagement on the connecting screw rod of described threaded bore upper end, the stage casing of flexible bar is provided with the main through hole of strip in addition, threaded bore is installed in the main through hole, described elastic rod comprises two bodies of rod that horizontal direction parallel is provided with, every body of rod all is provided with the horizontal through hole of a strip at two ends, article two, girt is applied in respectively in the horizontal through hole at two body of rod two ends, all is set with pull-rod nut by threaded engagement on every girt.
Beneficial effect of the present invention is: simple in structure, easy to use, can once take out root of the tooth, and speed is fast, surgical wound is little, and patient's misery is little.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the structural representation of another embodiment of the present invention.
Fig. 3 is the structural representation of another embodiment of the present invention.
The specific embodiment
As shown in Figure 1, root of the tooth plucking device of the present invention, comprise threaded bore 1, the lower end of described threaded bore 1 is provided with tapping screw thread, and the upper end of threaded bore 1 is provided with connecting screw rod, be set with threaded bore nut 2 by threaded engagement on the connecting screw rod of described threaded bore 1 upper end, in addition the stage casing of flexible bar 3 is provided with the main through hole 31 of strip, and threaded bore 1 is installed in the main through hole 31, threaded bore 1 can be in main through hole 31 move left and right, adjust the position, aim at the root of the tooth that needs operation.Described elastic rod 3 comprises two bodies of rod that horizontal direction parallel is provided with, every body of rod all is provided with the horizontal through hole 8 of a strip at two ends, article two, girt 9 is applied in respectively in the horizontal through hole 8 at two body of rod two ends, all is set with pull-rod nut by threaded engagement on every girt 9.
During use, the two ends of elastic rod 3 are placed on the healthy tooth of the root of the tooth both sides that need operation, the tapping screw thread of threaded bore 1 lower end aimed at the root of the tooth center and rotate threaded bore 1 make it creep into root of the tooth, continue rotation threaded bore 1 makes it creep into root of the tooth more and more deeply, matching thread auger shell mother 2 tightens, and elastic rod 3 stress deformations just can be extracted root of the tooth when the deformation force of elastic rod 3 is enough big, this moment, root of the tooth still was connected on the threaded bore 1, took out threaded bore 1 and got final product.
For elastic rod 3 being installed in reliably on the healthy tooth that closes on, can adopt as Fig. 2, improved embodiment shown in Figure 3.As shown in Figure 2, the two ends of described elastic rod 3 respectively are provided with the secondary through hole 7 of a strip, and an adjustable connecting rod 4 is set in the secondary through hole 7, and the upper end of described connecting rod 4 is connected with adjusting nut 5 by threaded engagement, the fixedly connected facing 6 in the lower end of connecting rod 4.Facing 6 is match with the shape of tooth bowl-shape.During use, the facing 6 at elastic rod 3 two ends is enclosed within respectively on two teeth, regulate the position of connecting rod 4 in secondary through hole 7 and be the gap between scalable two facings 6,, as above-mentioned embodiment 1, implement root of the tooth at last and pull out operation and get final product then by the fixed-site of adjusting nut 5 with facing 6.
As shown in Figure 3 among the embodiment, described elastic rod 3 comprises two bodies of rod that horizontal direction parallel is provided with, the two ends of the body of rod respectively are provided with the horizontal through hole 8 of a strip, and girt 9 is applied in the horizontal through hole 8 of two bodies of rod, is set with pull-rod nut by threaded engagement on the girt 9.Article two, elastic rod 3 and two girts 9 are common constitutes a quadrilateral frame shelf structure, utilizes nut on the girt 9 can adjust the gap between two elastic rods 3 and be fixed, and its effect also is that two elastic rods 3 are fixed on the tooth of two health.Threaded bore 1 still is arranged in two elastic rods 3 and two girts, 9 intermediary spaces.Using method is with above embodiment.
