Technical Field

[0001] The present application relates to the technical field of medical devices, and more specifically, to an extractor for dental implant surgery. Background Art

[0002] Dental implants usually consist of three parts: the implant, the abutment and the crown. Generally, screws are needed to fix the abutment and the crown to the implant in order to stabilize the implant.

[0003] At present, after dental implant surgery, a cover screw is required to close the screw hole on the implant. In the prior art, the doctor will cut the soft tissue of the gums over a large area with tools. In addition, the incision needs to be sutured after the operation.

[0004] The above surgical process will not only bring great pain to the patient, but also increase the difficulty of the doctor's operation, resulting in a very poor experience for both the doctor and the patient. Summary of the invention

[0005] In view of this, an embodiment of the present application provides an extractor for dental implant surgery.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-Figure 3 As shown, the implant surgery extractor provided in the embodiment of the present application includes a screw unscrewing rod 100, a plurality of beak edge pieces 200 and a clamp body 300, wherein a chamber 110 is provided inside the screw unscrewing rod 100, and the end of the screw unscrewing rod 100 is provided with a first opening connected to the chamber 110. The screw unscrewing rod 100 can be connected to a cover screw through the first opening, and the cover screw is placed in the chamber 110 inside it to achieve the function of fixing the cover screw. In addition, the side wall of the screw unscrewing rod 100 opposite to the first opening is connected with a support rod 120, and the support rod 120 and the first opening are respectively arranged at the two ends of the screw unscrewing rod 100.

[0029] A plurality of beak edge pieces 200 are provided at the first opening of the screw unscrewing rod 100. Specifically, the plurality of beak edge pieces 200 are equidistantly distributed at the first opening in a circular shape, and the plurality of beak edge pieces 200 are flexibly connected to the first opening. The beak edge piece 200 is a thin piece with a certain thickness, and the plurality of beak edge pieces 200 form a second opening 210 on the screw unscrewing rod 100. When used, the cover screw can be placed in the chamber 110 of the screw unscrewing rod 100 by opening the beak edge piece 200, thereby completing the removal process of the cover screw.

[0030] In this embodiment, the pliers body 300 is connected to the screw unscrewing rod 100 through the support rod 120. The pliers body 300 is a structure having two handles and cross-hinged connection. The two ends of the pliers body 300 include a driving end 310 and a movable end 320. The doctor can apply a force to the driving end 310 to make the movable end 320 perform a corresponding action. Specifically, pressing the driving end 310 can make the movable end 320 expand outward; conversely, the driving end 310 can make the movable end 320 gather inward. Preferably, a spring can also be provided between the driving ends 310.

[0031] Continue as Figure 1-Figure 3 As shown, the driving end 310 of the pliers body 300 is located outside the chamber 110 and on both sides of the support rod 120. The movable end 320 of the pliers body 300 penetrates the screw-out rod 100 and is located in the chamber 110, and the movable end 320 also abuts against the inner surface of the side wall of the beak edge piece 200. Therefore, when the driving end 310 is pressed to control the movable end 320 to move, the beak edge piece 200 can be driven to expand outward; conversely, when the driving end 310 is released, the beak edge piece 200 can return to its original position.

[0032] As for the structure in which the pliers body 300 is specifically connected to the screw unscrewing rod 100 via the support rod 120 , as long as the above-mentioned functions can be achieved, this embodiment will not be described in detail here.

[0033] In the dental implant surgery extractor provided in the embodiment of the present application, a plurality of beak edge pieces 200 can be expanded by the pliers body 300 so that the cover screw can enter the chamber 110 of the screw unscrewing rod 100. At the same time, using the pliers body 300 to expand the beak edge pieces 200 outward can also facilitate the doctor to open the patient's soft tissue gums, thereby increasing the doctor's observation field of view, so that the cover screw can be quickly removed. The above structural design can be used to conveniently, quickly and accurately remove the cover screw, and the entire surgical process will not produce a large wound, so it will not bring a large burden to the patient, and it can also improve the experience of both doctors and patients.

[0034] In some embodiments, the two driving ends 310 have bosses 311 extending outward on the sides close to the support rod 120, and the bosses 311 extend toward the support rod 120, and the surfaces where the two bosses 311 contact each other are provided with teeth 312. In contrast, the support rod 120 is provided with locking through holes 121 in the radial direction, and the outer diameter and shape of the locking through holes 121 are adapted to the bosses 311.

[0035] In a specific implementation, the bosses 311 of the two driving ends 310 can be passed through the locking through hole 121. Since the two driving ends 310 are staggered and have a certain degree of mechanical freedom with each other, the two can be fixed together by the teeth 312 so that the movable end 320 can maintain an expanded state, thereby facilitating the doctor to use the extractor to expand the patient's gingival soft tissue for corresponding treatment.

[0036] In some embodiments, the inner surface of the side wall of the beak edge piece 200 is provided with rough transverse lines 220. The beak edge piece 200 is connected to the covering screw via the rough transverse lines 220, which can increase the friction between the two, thereby facilitating the doctor to clamp the covering screw through the extractor and facilitate the subsequent removal of the covering screw.

[0037] In some embodiments, a guiding slope 230 is provided at the end of the beak edge piece 200 away from the screw unscrewing rod 100, and the inclination angle of the guiding slope 230 is adapted to the covering screw, so that the beak edge piece 200 can be further matched with the covering screw, thereby reducing the difficulty of removal.

[0038] In some embodiments, the guiding bevel 230 is further provided with a smooth tip 240, and the tip 240 is a thinned sheet structure, which can facilitate the doctor to insert the beak edge piece 200 into the wound of the patient, thereby achieving minimally invasive treatment.
