Description

Stump pulling device for stomatology

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a stump removing device for stomatology.

Background

Tooth extraction is one of the most common treatments in oral cavity diagnosis and treatment, and when tooth extraction is performed, the tooth root is broken and is retained in the depth of an alveolar bone due to factors such as tooth inflammation or anatomical abnormality of the tooth, so that the tooth extraction difficulty is increased. At present, for such stumps, only a part of gingiva can be cut firstly, alveolar bones near the stumps can be removed, and then the diseased teeth can be extracted by combining with the use of an extraction forceps and an extraction tappet. The method not only can damage the alveolar bone and the gingival tissue and bring great pain to the patient, but also can influence the prognosis of the tooth extraction wound of the patient due to excessive trauma. At the same time, the clinical experience and the operation level of the tooth extraction doctor are also very dependent. Therefore, aiming at the problems existing in the prior art, the stump pulling device for stomatology is designed.

Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model, but are not limited thereto.

Referring to fig. 1-2, the present utility model provides a technical solution: the utility model provides a stump pulling device for stomatology, which consists of a self-tapping screw cone (1), a screw column (2), a silica gel sleeve (3), a supporting body (4), a screw cap (5) and a screw seat (6). The self-tapping screw thread cone (1), the screw thread column (2) and the screw seat (6) are sequentially and coaxially connected; the screw thread column (2) is screwed with the screw cap (5), and the screw cap (5) has screwing function and can fix the supporting body (4); the threaded column (2) is fixed on the support body (4) through the insertion hole; the threaded column (2) is provided with a silica gel sleeve (3).

Specifically, the taper of the self-tapping thread cone (1) is 0.26.

Specifically, the threaded column (2) is a cylinder, the lower end of the threaded column (2) is connected with the self-tapping thread cone (1), and the upper end of the threaded column (2) is connected with the screw seat (6).

Specifically, the rotary seat (6) is a regular nine-prism.

Specifically, two ends of the support body (4) are provided with round observation holes.

Specifically, the radius of the screw cap (5) is 5mm, the thread distance is 0.5mm, and the thread radius is 0.5mm.

The application method of the utility model comprises the following steps: 1) Taking a root orifice of a tooth root as a drilling point, and preparing a conical hole with the depth of 8-10mm along the tooth root canal direction by using a split drill with the diameter of about 1.2mm through an elevation high-speed turbine handpiece. 2) The self-tapping screw thread cone (1) of the stump removing device is partially put into the conical hole, and then the rotary seat (6) is rotated clockwise, so that the stump and the device are fastened into a whole. 3) The silica gel sleeve (3) is screwed down to wrap the surface of the stump, and the reinforcing device is fixed. 4) The supporting body (4) is arranged on the occlusal surface or the alveolar bone of the front and rear adjacent teeth, the screw cap (5) is screwed clockwise to stably apply force, and the longitudinal tooth extraction force is generated when the device and the stump are stabilized, so that stump dislocation is facilitated. 5) The tooth forceps are used, and the forceps holding rotary seat (6) is used for pulling out the device and the residual root together, so that the residual root is pulled out.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
