Description

Repoussor

This utility model relates to a kind of repoussor, mainly is used for pulling out residual, disconnected root of the tooth for the stomatology field.

Tooth has corona 23 that exposes and the root of the tooth of imbedding in the alveolar bone 24 to see Fig. 4 and Fig. 5.The exodontia cause sometimes be completely cured and root of the tooth residual, cacodontia and wound also can cause sometimes be completely cured and root of the tooth residual.

The existing apparatus and method of uprooting comprise that root pincers get root, dental elevator and get root and turn over lobe cutter bone and get root.It is to take out the root of the tooth that is higher than alveolar ridge with pliers that root pincers are got root, and its weak point is to take out the root of the tooth that maintains an equal level with alveolar ridge or be lower than alveolar ridge.It is that rod member is rotated on the limit and the limit prizes, and prizes root of the tooth in tooth socket with in the other periodontal membrane of rod member (being dental elevator) the wedge insertion root of the tooth of band homalocephalus that dental elevator is got root, and its weak point is: can cause the damage of gingiva and alveolar bone; Sometimes also can injure surrounding soft tissue because of the dental elevator slippage.Turning over lobe cutter bone, to get root be to cut toppedly in the mucoperiosteum lobe at have tooth pulled out root place, peels off, overturns and cut the alveolar bone of topped root of the tooth, exposes root of the tooth, so that with clamping or endure taking-up.Its weak point is: the more macrolesion that can cause gingiva and alveolar bone; Bring bigger misery and the infection that may cause postoperative to the patient; Operate more time-consuming and bothersome.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art and provides a kind of wound repoussor little and easy and simple to handle.

The purpose of this utility model can reach by following measure: this utility model is made up of shell, power transmission shaft, joint, root pulling needle, root pulling aiguille and knob, knob, power transmission shaft, joint and root pulling needle are housed in the shell, screw is arranged on the shell, knob central authorities are porose, and revolving front end has claw and draw-in groove, and power transmission shaft has chuck, the power transmission shaft front end is connected with joint, the power transmission shaft leading portion has axle sleeve outward, and the root pulling needle tail end is connected with joint, and pin is bolted in knob draw-in groove and the root pulling needle draw-in groove.

Shell comprise back segment, leading portion and middle straight section or in curved section.

Joint has straight joint or back bent sub and preceding bent sub.

The straight joint two ends of joint have screw and many half-lune holes respectively, and the back bent sub two ends of joint have screw and tooth respectively, and the preceding bent sub two ends of joint have tooth and many half-lune holes respectively.

Root pulling needle comprises syringe needle, shank and backshank, and syringe needle is a screw thread, and backshank has draw-in groove and most cylinder.

Root pulling aiguille comprises drill bit, drilling rod and brill tail, and boring tail has draw-in groove and most cylinder.

25, root pulling aiguille

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:

Fig. 1 represents that this utility model is used to pull out the straight shape structure of preceding root of the tooth and premolars root, mainly is made up of shell, power transmission shaft 1, knob 2 and root pulling needle 3.The shell that is used for this straight shape structure is straight tubular, is made of back segment 4, middle straight section 21 and leading portion 22, and back segment has helicitic texture to be connected with middle straight section and middle straight section with leading portion, and knob, power transmission shaft and root pulling needle or root pulling aiguille are housed in the shell.There is chuck 5 in the power transmission shaft stage casing, and front end has screw thread.Knob central authorities are porose, for the usefulness that is set in power transmission shaft.There are claw 6 and draw-in groove 7 in the knob front portion, and the knob claw is packed in the straight trough of power transmission shaft chuck, and the hands turning knob is to drive the power transmission shaft rotation.The back segment 4 of shell has screw 8, the usefulness that supply and marketing bolt 9 is screwed into, in knob is packed shell into after, the pin front end stretches into the knob draw-in groove, outwards deviates to prevent knob, Figure 1 shows that the state after knob breaks away from power transmission shaft.The power transmission shaft leading portion has axle sleeve 10 outward, rotates in axle sleeve hole in order to power transmission shaft.The power transmission shaft front end has joint, and the joint of the straight shape structure of basis is a straight joint 11, and there is screw the straight joint rear end, and confession power transmission shaft front end is screwed into the usefulness to connect.The straight joint front end is most circular ports, and for the usefulness that the most cylinders of root pulling needle tail end are packed into, this just most round structures guarantee that the straight joint of following the power transmission shaft rotation can drive the root pulling needle rotation.Root pulling needle comprises syringe needle 12, shank 13 and backshank 14 (also seeing Fig. 2), and syringe needle is a tapping screw thread, after syringe needle enters and rotates root pipe 15 (see figure 5)s of shooting root of the tooth, just root of the tooth can be extracted.Backshank has draw-in groove 16 and most cylinder 17, and cylinders are for rotating together in many semilunes hole shape of the straight joint of packing into and in company with straight joint mostly.The back segment of shell has screw 8, and supply and marketing bolt 9 is screwed into, and pin inspection front end is entered in the draw-in groove of root pulling needle or root pulling aiguille, moves axially to prevent root pulling needle or root pulling aiguille.

Fig. 3 represents that this utility model is used to pull out the bending structure of distomolar root and wisdom teeth root, mainly is made up of curved cylindrical outer casing, power transmission shaft 1, knob 2 and root pulling needle 3.Curved cylindrical outer casing by back segment 4, in curved section 18 and leading portion 22 constitute, back segment and in curved section and in being connected by helicitic texture together of curved section and leading portion.Be loaded on shell in a joint in the curved section back bent sub 19 and preceding bent sub 20 are arranged, there is screw back bent sub rear end, front end has tooth.Before the rear end of bent sub tooth is arranged, carry out engaged transmission with the tooth of back bent sub, preceding bent sub front end has most circular ports.

During use (also referring to Fig. 5), earlier this utility model is removed knob and root pulling needle, to have the mobile straight handpiece power transmission shaft 1 that is being installed now, be loaded on the position of root pulling needle with root pulling aiguille 25, the brill tail of root pulling aiguille is identical with root pulling needle with the structure of drilling rod, promptly boring tail has draw-in groove and most cylinder, and front end is a drill bit.Start straight handpiece, drive the root pulling aiguille rotation, the root pipe 15 of drill bit root of the tooth is entered the root of the tooth deep.Remove straight handpiece and root pulling aiguille then, load onto root pulling needle and knob, root pulling needle is stretched in the root pore that has got out, hand-screw changes knob, drives the rotation of root pulling needle front end tapping screw thread to shoot the root of the tooth deep, outwards pulls up this utility model, just root of the tooth can be extracted.

The utility model contrast prior art has following advantages: hinder little to painful little, plane that dental patients is brought With no postoperative infection; Easy and simple to handle, time saving and energy saving.
