Embodiment 1

[0039] The primary peeling structure peels off the maxillary sinus floor mucosa: slowly put the hollow sleeve 2 into the bone hole 10, hold the hollow sleeve 2 or the handle end 3, peel off the mucosa with the peeling blade 1, and slowly rotate the hollow sleeve 2 horizontally to remove the maxillary sinus bottom. The mucosa 11 is peeled off in one circle, and a peeling range of about 3 mm around the reaming hole is obtained.

Embodiment 2

[0041] The secondary stripping structure strips the maxillary sinus floor mucosa: slowly put the hollow sleeve 2 into the bone hole 10 (at this time, the stripping wire 8 is hidden in the stripping blade 1), operate the elastic wire 4 or the stopper 7 to make the stripping wire 8 move along the The stripping blade 1 stretches out forward and downward. Choose the appropriate stripping length according to the height that needs to be lifted.

Embodiment 3

[0043] The secondary stripping structure strips the maxillary sinus floor mucosa: slowly put the hollow sleeve 2 into the bone hole 10 (at this time, the stripping wire 8 is hidden in the stripping blade 1), operate the elastic wire 4 or the stopper 7 to make the stripping wire 8 move along the The stripping blade 1 stretches out forward and downward. Further, horizontally rotating the hollow sleeve 2 or the gripping end 3 drives the peeling wire 8 to rotate, centering on the midpoint of the reaming hole and rotating perpendicular to the reaming plane, so that the surrounding mucosa can be peeled off in a large range.

Abstract

The invention discloses a memory elastic wire casing pipe for stripping the maxillary sinus mucosa. The memory elastic wire casing pipe is suitable for planting and (or) bone grafting operations in the area near the maxillary sinus bottom. The memory elastic wire casing pipe comprises a primary stripping structure and a secondary stripping structure, the primary stripping structure of the memory elastic wire casing pipe can be used for primarily stripping the maxillary sinus bottom mucosa, and the maxillary sinus bottom mucosa can be further stripped through the secondary stripping structure. The memory elastic wire casing pipe completes five kinds of operation in the implementation process, the maxillary sinus mucosa can be safely and effectively stripped in a large range, meanwhile, the memory elastic wire casing pipe has the advantages of being simple and small in equipment and the like, and very good clinical application value is achieved.

Description

technical field [0001] The invention relates to a medical device, in particular to a memory elastic silk sleeve for peeling off the maxillary sinus bottom mucosa, which is suitable for planting and (or) bone grafting operations for separating the maxillary sinus bottom mucosa. Background technique [0002] Oral implantology is one of the fastest-growing fields of stomatology in recent years. When the alveolar ridge in the maxillary molar region is usually close to the maxillary sinus floor, the implant often increases due to too little bone combined with the implant. body failure rate. The maxillary posterior region with insufficient vertical bone mass was once considered a forbidden area for dental implants. Once the maxillary sinus lifting technique is proposed, it is possible to solve the above problems. The maxillary sinus lifting operation is divided into maxillary sinus floor lifting with side wall fenestration, that is, external maxillary sinus lifting (Tatum OH.Max...
