Description

Bone chisel lifting instrument in maxillary sinus

Technical Field

The utility model relates to a promote osteotome apparatus in maxillary sinus belongs to medical instrument technical field.

Background

Maxillary sinus floor lift, also known as internal lift via alveolar ridge approach. Currently, there are many operating methods internationally for maxillary sinus floor lift, but the most common, most economical and reliable method is the surgical technique proposed by Summers in 1994 using bone chiseling. The technique adopts a set of osteotomes, the diameter of the foremost end of the osteotome is 1.8mm, 2.0mm, 3.0mm and 3.2mm, the central part of the front end of the osteotome is concave, and the edge is slightly sharp. During operation, the first-stage osteotome is used for knocking the maxillary sinus floor bone plate to slight fracture by using certain force, then the osteotomes with different diameters are used for knocking into the maxillary sinus step by step, the maxillary sinus floor is pushed upwards by about 5-6 mm, and the maxillary sinus is lifted in a closed manner. Carry on through alveolar ridge top approach maxillary sinus when promoting the art, the art district has the mucous membrane, the blood exists in addition simultaneously of blockking of adjacent tooth, make the operation field of vision limited, the scale of difficult recognition apparatus work end sign, thereby be difficult to observe the degree of depth that the work end got into, the art person need use the bobbing to strike when carrying out this operation simultaneously, hold the osteotome on one hand usually, another handheld hammer strikes, still observe the apparatus through the degree of depth that strikes the back and get into simultaneously, through striking dynamics control depth, the operation is inconvenient, because patient sclerotin is different, need use great power when carrying out hard sclerotin patient, if the art person easily appears the hammer slippage when the clear condition in the field of vision hand eye cooperation mistake, thereby injure and patient or art person.

Disclosure of Invention

To the above-mentioned defect that exists among the prior art, the utility model provides a can prevent that the osteotome from getting into the maxillary sinus too deeply, avoid haring the mucous membrane, and promote the osteotome apparatus in convenient operation's the maxillary sinus.

The utility model discloses a realize through following technical scheme: the utility model provides a promote osteotome apparatus in maxillary sinus which characterized by: the sliding hammer is slidably sleeved on the operating end of the main body, and the main bodies at the two ends of the sliding hammer are respectively provided with a limiting structure.

The utility model discloses in, only stop its position in working head one end of ring accessible screw thread rotation control, play the purpose that the co-altitude stops, block sinus floor bone in relevant position through stopping the steerable osteotome of ring, prevent that the osteotome from getting into the maxillary sinus too deeply to avoid damaging the mucous membrane. The sliding hammer can slide between the limiting structures at the two ends of the sliding hammer, and a certain knocking force is applied to the working head through the sliding knocking of the sliding hammer, so that the osteotome can be conveniently knocked into the maxillary sinus.

Further, limit structure is limiting plate and nut, nut threaded connection be in the tip of the operation end of main part, the limiting plate set up at the slide hammer inboard with main part fixed connection.

Furthermore, the end part of the working head is a concave groove or a convex body. The end of the working head adopts a concave groove or a convex body to adapt to patients with different sclerotin, wherein the end of the working head adopts the concave groove and is mainly used for the maxillary sinus internal lifting operation of the general sclerotin patient through the alveolar ridge approach, and the end of the working head adopts the convex body and is mainly used for the maxillary sinus internal lifting operation of the osteoporosis patient through the alveolar ridge approach.

Further, the diameter of the working head is 2.2mm or 2.8mm or 3.5mm or 4.2mm or 2.0mm or 2.5mm or 3.0mm or 3.5mm or 4.0mm or 4.5 mm.

The utility model has the advantages that: the utility model has simple structure, can achieve the purpose of stopping at different heights by arranging the stopping ring, can control the osteotome to clamp the alveolar ridge crest bone below the bottom of the maxillary sinus at the corresponding position, and prevents the osteotome from entering the maxillary sinus too deeply so as to avoid damaging mucous membranes; through set up the sliding hammer at the operation end, utilize the percussion action of sliding hammer to replace handheld hammer operation, make the operation more convenient, the operator of being convenient for operates. Furthermore, the utility model discloses an adopt two sets of working heads, can make things convenient for the operator to select interior promotion and the bone extrusion under promoting and the loose sclerotin condition in carrying out the maxillary sinus.

Detailed Description

The invention will now be further described by way of non-limiting examples with reference to the accompanying drawings:

as shown in the attached drawings, the bone chisel lifting device in the maxillary sinus comprises a main body 1, a stop ring 2 and a sliding hammer 3. The main body 1 is of a rod-shaped structure, one end of the main body 1 is a working head, the other end of the main body is an operating end, and external threads are arranged on the outer portion of one end of the working head of the main body 1. The inner wall of the stop ring 2 is provided with an internal thread which can be matched with the external thread on one end of the working head of the main body 1, and the stop ring 2 is connected with the outer part of one end of the working head of the main body 1 in a threaded manner. The sliding hammer 3 is provided with a through hole, the sliding hammer 3 is slidably sleeved on the operation end of the main body 1 through the through hole on the sliding hammer 3, the main body 1 at two ends of the sliding hammer 3 is respectively provided with a limiting structure, and the sliding hammer 3 can slide on the main body 1.
