Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an implant positioning device. Background Art

[0002] With the continuous development of oral implant technology, dental implant technology is becoming more and more mature. Its characteristics such as beautiful and comfortable, no need for teeth grinding, and good recovery of chewing function are gradually recognized and accepted by people. Oral implant surgery is to drill a hole in the alveolar bone of the oral cavity, implant the implant in the hole, then install the base (i.e. connector) on the implant, and finally install the porcelain tooth on the base. The key to this operation is that when drilling, there must be no deviation in the position and axis of the hole, otherwise the implanted implant will be skewed or offset, resulting in unsuccessful surgery and affecting the surgical repair effect of the patient. In existing clinical practice, due to the influence of the patient's cause of tooth loss, the location of the loss, the height and width of the remaining alveolar bone, and the condition of the soft tissue, doctors determine the position and axis of the drilling based on clinical experience, which poses a great medical risk.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] As shown in the accompanying drawings, an implant placement positioning device comprises a main caliper 1, a first baffle 2 and a second baffle 3. The main caliper 1 is provided with a first scale 4, and the top and bottom of the main caliper 1 are respectively provided with a first slideway 5; the first baffle 2 is provided at one end of the main caliper 1 and is perpendicular to the main caliper 1;

[0022] The second baffle 3 is perpendicular to the main caliper 1 and parallel to the first baffle 2. The end of the second baffle 3 close to the main caliper 1 is arranged on the first slide bar 6. The first slide bar 6 is installed on the first slideway 5. The second baffle 3 is a hollow ring. The second baffle 3 is provided with a second scale 7. The bottom and top of the second baffle 3 are respectively provided with a second slideway 8. The second slideway 8 is installed with a second slide bar 9. The second slide bar 9 is provided with an annular hole 10 and a strip hole 11 that are interconnected. The annular hole 10 is located at the top of the strip hole 11. A positioning rod 12 is provided in the annular hole 10. The positioning rod 12 is "L"-shaped. A positioning pin 13 is provided at the end of the positioning rod 12 close to the first baffle 2, and a limit plate 14 is provided at the end of the positioning rod 12 away from the first baffle 2.

[0023] In this embodiment, the zero scale line of the first scale 4 is located at one end close to the first baffle 2 ; the zero scale line of the second scale 7 is located at one end close to the main caliper 1 .

[0024] In this embodiment, the second slide bar 9 is made of elastic rubber material, the diameter of the positioning rod 12 is smaller than the inner diameter of the annular hole 10 and the width of the strip hole 11 , and the diameter of the positioning rod 12 is larger than the width of the connection between the annular hole 10 and the strip hole 11 .
