Background

The periosteum elevator is an indispensable operation technique in various oral operations, and the protection of the periosteum is crucial to the blood supply and survival of the lifted periosteum flap, the regeneration of bone tissues, the tight closing of an operation area and the anti-infection capability, so that the preservation of the basic integrity of the oral periosteum is favored by oral doctors more and more. At present, strippers for oral surgery are various and can only basically meet the requirements of periosteum stripping in various oral surgeries. The stripping surgical instrument is too simple, and is inconvenient in clinical use, for example, bleeding of a periosteum and bleeding of a bone face nourishing bone hole often cause that an operator can not clearly see the boundary between the periosteum and the bone face in a periosteum stripping process, and the operator needs to keep the surgical field clear by using vacuum suction equipment for an assistant except the operator, but in the general anesthesia operation process, due to the limitation of the oral cavity space position, the assistant can not directly view the surgical field, and the suction equipment can not be well utilized to keep the surgical field clear, so that the operation efficiency is reduced, and the operation duration is prolonged. At the present stage, periosteum stripping mainly depends on vascular clamps, conventional strippers, suction apparatuses and the like, and no proper instrument for simultaneously solving stripping and suction exists.

Detailed Description

The utility model is mainly applied to periosteum stripping in oral general anesthesia and local anesthesia operations, and fully exposes the operative field. The method mainly comprises the following steps: periosteum stripping in maxillary fracture, mandibular fracture and zygomatic fracture incision reduction internal fixation, gingival flap surgery and capsule wall stripping in cyst surgery and periosteum stripping in orthognathic surgery; gingival flap during implant surgery and obturating odontostomy. In addition, the stripper can also be used as a draw hook to block the influence of mucosa on the operation.

For example, maxillary periosteum flap is the first step of maxillary fracture surgery and is also an extremely important step, conventional personnel are equipped with four persons in the surgery process, namely, the surgeon (positioned on the right side of the head), one person (positioned on the left side of the head), two persons and three persons (positioned on the top end of the head), the conventional operation is that the surgeon holds the conventional stripper to strip the periosteum, one assistant holds curved forceps to protect the periosteum and maintain the surgery field, the two persons and the retractor hold the aspirator and the retractor to maintain the sight of the surgery field and suck and remove exuded blood, but because of the mouth opening direction and the position of the assistant, the assistant holding the aspirator cannot often see the position where the surgeon strips the periosteum, and cannot timely remove the blood in the surgery area for the surgeon.

When an operator holds the detacher in the utility model, one surface with the suction holes faces to the bone surface to suck blood at the same time, and the other surface faces to the mucosa, so that the bone membrane is prevented from being blocked while the bone membrane is prevented from being damaged due to the adsorption of the bone membrane by the suction holes, thereby improving the operation efficiency and the operation quality and better serving patients.

The technical solution of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 3, the present invention provides a stripper with suction function for oral surgery, which comprises a blade part 2, a neck part 3, a handle 4 and a suction apparatus connection port 5, wherein the blade part 2 is connected to the front end of the neck part 3, the handle 4 is connected to the rear end of the neck part 3, the other end of the handle 4 is connected to the suction apparatus connection port 5, and the suction apparatus connection port 5 can be connected to a suction apparatus; the blade part 2, the neck part 3, the handle 4 and the suction apparatus connecting port 5 are all hollow structures; the blade part 2 is a wide-face bending structure, and the inner side of the bending face is provided with a suction hole 1. The handle 4 can be designed into a column shape, a prism shape, a fusiform shape and the like.

In a preferred embodiment of the present invention, in order to ensure that the stripper can directly adhere to the bone surface to strip a large area of the periosteum and avoid unnecessary trauma to the patient, the width of the blade 2 is 0.5-1.0 cm. The blade parts with different sizes and shapes can be adopted according to the requirements of different operations, and the utility model is suitable for various oral mucosa flap operations.

In order to rapidly and comprehensively suck blood near the periosteum and ensure the strength of the blade part when the periosteum is stripped, a shape of the suction hole 1 formed in the blade part 2 is narrow on the side close to the handle 4 and wide on the side far from the handle 4. The shape of the suction hole 1 may be an inverted triangle in the drawing, or may be another shape having a wide outer side and a narrow inner side, such as a semicircle.

As a better embodiment of the utility model, in order to adjust the suction force of the stripper according to the situation in use, a suction adjusting hole 6 is arranged on the handle 4. When the suction force of the stripper is adjusted, the area of the suction adjusting hole 6 pressed by the hand can be changed. When the regulating hole is fully opened, the suction force (negative pressure) is minimum, and conversely, the suction force (negative pressure) is maximum.

A suction hole adjusting sleeve can be arranged near the suction adjusting hole on the handle, and when the hand is inconvenient to press in use, the suction hole adjusting sleeve can be moved to the suction adjusting hole to adjust the internal suction (negative pressure) of the stripper.

As a more preferable embodiment of the present invention, in order to prevent the hand from slipping when the peeler is used, the handle 4 is provided with an anti-slip pattern.

In order to make the stripper tightly connected with the vacuum device, the suction device connecting port 5 is provided with a thread matched with the vacuum device.

As a more preferred embodiment of the present invention, the peel sub-blade 2 is movably connected to the neck 3, neck 3 and handle 4 to enable cleaning, disinfection and quick change of the blades for different procedures. The length of the neck part can be designed into different sizes, and the neck part with different length can be replaced.

The oral mucosa is a special mucosa in the whole body, most of the oral mucosa has no subepithelial layer, has the characteristics of thin tissue, crisp texture and rich blood circulation, is very easy to tear in the process of stripping the mucoperiosteum by an operation, and brings unnecessary injury to patients. The utility model has the advantages of realizing the stripping of the periosteum and the suction function, reducing operation errors, improving operation efficiency and shortening operation time. Meanwhile, the cutting part has a certain width, can be directly attached to the bone surface, peels off a large area of the bone adhesion membrane, and avoids unnecessary trauma to the patient.
