Description

Technical Field

[0001] The utility model relates to the technical field of tooth apex surgical instruments, in particular to a scraping tool for apex surgery. Background Art

[0002] Periapical surgery is an oral surgical procedure for lesions around the root apex of a tooth. By removing the diseased root apex tissue and clearing the infection source, it can promote the healing of the periapical tissue and restore the normal function of the tooth.

[0003] During apical surgery, it is often necessary to scrape the granulation tissue on the lingual side of the tooth root. However, due to the obstruction of the tooth root, scraping with existing instruments is very difficult, resulting in incomplete scraping. The remaining granulation tissue will slow down the healing of the apical bone defect and may mask some of the causes of apical inflammation, leading to failure of apical surgery.

In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but this must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0022] The present invention provides a scraping tool 100 for apical surgery. Figure 1As shown, it includes: a handle 110, a neck 120 and a digging spoon head 130. The handle 110 is connected to the digging spoon head 130 through the neck 120, and the neck 120 is bent at 80° to 100°. The digging spoon head 130 is shovel-shaped, and a tip 131 is provided at the end of the digging spoon head 130 away from the neck 120.

[0023] The working principle and beneficial effects of the above technical solution are as follows: The shovel-shaped design of the digging spoon head 130 of this apical surgical scraping tool 100 facilitates access to difficult-to-scrape areas of the tooth root, resolving the problem of acute angles between apical lesions and the tooth surface, which make it difficult to scrape cleanly. The specially designed angle of 80°-100° more effectively scrapes away diseased tissue directly behind and laterally from the tooth root, reducing residual granulation tissue, accelerating the healing of apical bone defects, and improving surgical outcomes.

[0024] Further, see Figure 1 , cutting edges 132 are provided on both sides of the tip 131 .

[0025] The working principle and beneficial effects of the above technical solution are as follows: the cutting edge 132 can cut the diseased tissue, further improving the scraping effect.

[0026] In one embodiment, the angle between the two sides of the tip 131 is 30° to 40°.

[0027] The working principle and beneficial effects of the above technical solution are: it can penetrate deeper into the difficult-to-scrape areas of the bone cavity in the surgical area, thereby scraping them cleanly. If the angle is too large, it is difficult to penetrate into the deep and narrow areas of the bone cavity, and if the angle is too small, the scraping efficiency is low.

[0028] Specifically, the neck 120 is bent at an angle of 90°.

[0029] The working principle and beneficial effects of the above technical solution are: better fit to the tooth surface and easy operation.

[0030] Optionally, the tool may be an integrated structure or a combined structure.

[0031] In one embodiment, the neck 120 is detachably connected to the key head 130 .

[0032] The working principle and beneficial effects of the above technical solution are: it is convenient to replace the key head 130 of different sizes and models, and it is also convenient to replace the handle of the neck with different angles (80°-120°), so as to cope with more clinical situations and perform targeted surgical operations.

[0033] Optionally, the connection between the neck 120 and the key head 130 can be one or more of threaded connection, snap connection, bonding, plug-in connection, and magnetic connection.

[0034] Specifically, a threaded hole is provided at one end of the neck 120 away from the handle 110 , and a threaded column is provided at one end of the digging spoon head 130 away from the tip 131 , and the digging spoon head 130 is threadedly connected to the neck 120 .

[0035] The working principle and beneficial effects of the above technical solution are: easy operation and strong connection stability.

[0036] In one embodiment, the handle 110 , the neck 120 , and the key head 130 are all made of metal.

[0037] The working principle and beneficial effects of the above technical solution are: convenient disinfection and sterilization, and high reliability.

[0038] Optionally, the handle 110 , the neck 120 , and the digging spoon head 130 may be made of titanium alloy, aluminum alloy, stainless steel, zinc-nickel alloy, or other metal materials respectively.

[0039] Specifically, the handle 110 , the neck 120 and the digging key head 130 are all made of stainless steel.

[0040] The working principle and beneficial effects of the above technical solution are: low cost, stable chemical properties, and convenient disinfection and sterilization for repeated use.

[0041] In one embodiment, the surface of the handle 110 is provided with anti-slip lines 111 .

[0042] The working principle and beneficial effects of the above technical solution are: easy operation, stable grip, and anti-slip.

[0043] Preferably, the scraping tool 100 for apical surgery further includes a silicone sleeve 112 , which is detachably mounted on the outside of the handle 110 .

[0044] The working principle and beneficial effects of the above technical solution are: it is conducive to further improving the operating comfort and grip stability, and the silicone sleeve 112 is movable and replaceable, which is convenient for adjusting the grip position.

[0045] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention.
