Embodiment 1

[0044] Such as Figure 1-4As shown, a capless locator 1 of the present invention includes a columnar portion 103 and a pile head 105. The columnar portion 103 and the pile head 105 are integrally made of a special material, and the special material needs to be decomposable and can be used by the human body. The characteristics of absorption should also have the characteristics of hot melt and plasticity, and the material can be specifically selected from polylactic acid and its polymer materials.

[0045] Such as figure 1 or 3, the circumferential sidewall of the columnar portion 103 has protrusions in different directions, and adjacent protrusions protrude in different directions to form staggered layers, and scrape collection grooves 104 are formed between the staggered layers. The sump 104 can scrape and collect bone powder on the side wall of the bone hole.

[0046] The protrusion of the columnar part 103 above can be designed as a square, rectangular, U-shaped or concav...

Embodiment 2

[0051] Such as Figure 1-4 As shown, a capless locator 1 of the present invention includes a columnar portion 103 and a pile head 105. The columnar portion 103 and the pile head 105 are integrally made of a special material, and the special material needs to be decomposable and can be used by the human body. The characteristics of absorption should also have the characteristics of hot melt and plasticity, and the material can be specifically selected from polylactic acid and its polymer materials.

[0052] Such as figure 1 or 3, the circumferential sidewall of the columnar portion 103 has protrusions in different directions, and adjacent protrusions protrude in different directions to form staggered layers, and scrape collection grooves 104 are formed between the staggered layers. The sump 104 can scrape and collect bone powder on the side wall of the bone hole.

[0053] Such as figure 1 Or as shown in 3, the pile head 105 is dovetail or V-shaped, and the pile head 105 is p...

Embodiment 3

[0058] Such as Figure 2-9 As shown, a capped positioner 1 of the present invention includes a columnar part 103, a pile head 105 and a tail cap part 102; the columnar part 103, the pile head 105 and the tail cap part 102 are integrally made of special materials, The pile head 105 and the tail cap 102 are respectively connected to the front and rear ends of the columnar part 103. The special material needs to be decomposable and absorbed by the human body, and should also have the characteristics of heat melting and plasticity.

[0059] Such as Figure 5 As shown in or 9, there are protrusions in different directions on the circumferential side wall of the columnar portion 103, and adjacent protrusions protrude in different directions to form staggered layers, and scrape collection grooves 104 are formed between the staggered layers. The sump 104 can scrape and collect bone powder on the side wall of the bone hole; the protrusion can be designed as a square, a rectangle, a U ...

Abstract

The invention relates to a locator for human bone surface reconstruction, which belongs to the field of artificial repair of human bones such as flat bones, long bones, and regular bones. Shape, a number of protrusions are set on the peripheral surface of the columnar part, all the protrusions are distributed along the length direction of the columnar part, adjacent protrusions are arranged in dislocation, and a scraping set for bone meal collection is formed between adjacent protrusions Groove; pile head, which is integrally formed with the columnar part, and is made of hot-melt material that can be absorbed by the human body. The pile head is located at the nailing end of the columnar part, and a V-shaped groove is arranged on the pile head. The opening direction of the V-shaped groove is the same as the nailing direction of the pile head; the V-shaped groove is used for bone residue accumulation; the straight-line nailing method will not cause damage to the side wall of the bone hole caused by tapping, and at the same time, the pile The V-shaped groove design on the head can gather the bone slag and avoid the damage of the bone slag to the bone hole. In addition, the design of the scraping groove can gather the bone powder on the side wall of the bone hole, thus avoiding the dissolution and penetration of the bone powder in the positioner. obstacles in.

Description

technical field [0001] The invention relates to a locator for reconstruction of human bone surfaces, which belongs to the field of artificial repair of human bones such as alveolar bones, skulls, and pelvic bones. Background technique [0002] When the human body grows with age, human bones tend to be prone to bone cracks or tooth loss. In the cracks of bone cracks or the alveolar bone after tooth loss often occurs due to material exchange between bones and human tissues, but there are bone cracks. Or the alveolar bone is often unable to retain bone elements, resulting in bone atrophy at the position of the fracture or the alveolar bone. The following will take the alveolar bone as an example to explain the causes and effects of bone atrophy. [0003] The alveolar bone, also known as the alveolar process, is the protrusion of the jaw that surrounds the root of the tooth; the socket that accommodates the teeth is called the alveolar fossa, the alveolar bone between two teeth...
