Problems solved by technology

However, conventional maxillary sinus lifting surgical tools have a single function, do not have versatility and complementary functions, and the depth control of the crowning is often limited by the screw-fastened limit block, so there is a risk of slippage

Embodiment Construction

[0047] figure 1 It is a schematic diagram of the overall structure of the present invention. A complete set of maxillary sinus lifting surgical tools of the present invention consists of six parts: base 1, slider assembly 2, button assembly 3, ejector 4, scraper 5 and filling Device 6; wherein the purposes of the former 1, 2, and 3 parts are to place and preserve the latter two parts 5 and 6.

[0048] Such as figure 2 As shown, the base 1 has a square structure, the outer surface of the base 1 is distributed with a number of rails 1a, the rear of the base has a boss 1b, and the boss 1b is sequentially distributed with 6 holes embedded with silicone rings 1e 1c, there are three protrusions 1d on the inner surface of the silicone ring 1e to enhance the holding force. The scraper 5 and the stuffer 6 are inserted into the holes, and can be pulled out gently when in use.

[0049] Such as image 3 As shown, the slider assembly 2 is composed of a slide plate 2a, a front bracket 2...

Abstract

The invention relates to the field of medical equipment, in particular to an osteotome maxillary sinus elevation operation tool assembly which comprises a base, slider components, button components, bone condensers, scrapers and fillers. A boss located on the rear portion of the base is provided with holes which the scrappers and the fillers can be inserted in, tracks are distributed on the surface of the boss, the slider components can be clamped in the tracks, and the bone condensers are fixed to the slider components through front supports and rear supports. When the bone condensers are used, the button components are pressed to push out the bone condensers. The invention involves two scrappers and four fillers. According to the osteotome maxillary sinus elevation operation tool assembly, the distance between the head portion of each bone condenser and the inside of a bone hole is limited in ejection through the design of the bone condensers, and the condition that the maxillary sinus film is damaged in an operation is avoided. The osteotome maxillary sinus elevation operation tool assembly can be conveniently disassembled and cleaned and disinfected in a concentrated mode. The condensers are tightly arranged, and therefore a storage space can be saved. The condensers which are tightly arranged can be conveniently picked through the assembled button components.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a complete set of maxillary sinus lifting surgical tools. Background technique [0002] In 1965, Professor Branemark, the father of modern dental implantology, used endosseous implants to complete the implant restoration of the full edentulous jaw, marking the official birth of dental implant technology. Over the past 50 years, with the continuous development of implant restoration technology, oral implant technology has become recognized as the best method to repair dentition defects and missing. Due to osteoporosis, excessive pneumatization of the maxillary sinus, alveolar resorption after tooth loss, and congenital dysplasia of the maxillary sinus in the posterior maxillary region, the vertical bone mass of the alveolar ridge will be insufficient. The bone height needs to be around 8-12mm, which directly leads to more complex dental implant restoration technology in the pos...
