Description

A mucoperiosteal flap spreader for oral implantation

technical field

The invention belongs to the technical field of oral cavity treatment, and in particular relates to a mucoperiosteal flap spreader for oral implantation.

Background technique

In recent years, with the development of oral implant technology, dental implants are favored by patients with missing teeth and dentists due to their good functionality, aesthetics and comfort. Dental implants are artificial teeth composed of implants in the bone and the connecting structures and restorations above them. The implant is implanted into the alveolar bone through implant surgery, and forms a good combination with the alveolar bone through the osseointegration mechanism to support the upper repair structure of the implant. Implant surgery usually needs to expose the alveolar bone in the edentulous area, and good exposure of the surgical area is very important for the operation of implant surgery.

The inventor believes that: in existing clinical operations, a periosteum peeler is used to expose the periosteum flap, that is, the peeler is used to pull the periosteum flap after incision to the buccal side, so that the alveolar bone is exposed.

The exposure of the surgical site is not ideal; and only the buccal mucoperiosteal flap can be peeled off, and it is inconvenient to peel off the lingual mucoperiosteal flap to expose the lingual surgical field, and the exposure range of the surgical area is small and incomplete.

At the same time, the mucoperiosteal stripper requires special medical staff to hold it hard throughout the operation, which wastes manpower.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art above, to provide a mucoperiosteal flap spreader for oral implantation, which can realize the expansion of mucoperiosteal flaps on the buccal and lingual sides at the same time, and better expose the surgical field of view; During the operation, the mucoperiosteal flap can be opened without being held by medical staff.

In order to achieve the above object, the present invention adopts the following technical scheme: it includes a first clamper and a second clamper, and the first clamper and the second clamper are used to clamp the teeth of the teeth on both sides of the dental implant area. Neck, two telescopic rods arranged in parallel are connected between the first clamper and the second clamper, and the two ends of each telescopic rod are respectively connected with the first clamper and the second clamper;

Each telescopic rod includes a rod sleeve and an extension rod, and the extension rod can extend a set length along the rod sleeve to change the distance between the first clamper and the second clamper.

The use of the first clamper and the second clamper enables the entire device to be fixed on both sides of the area of the tooth to be operated, and the buccal The buccal and lingual mucoperiosteal flaps are stretched, and the two telescopic rods can respectively stretch the buccal and lingual mucoperiosteal flaps in the area to be operated. After the surgical field of view is exposed, no special medical staff is required to hold it.

Each telescopic rod includes a rod sleeve and an extension rod, and the extension rod can extend out a set length along the rod sleeve and be fixed.

The telescopic rod can be stretched to change the distance between the first clamper and the second clamper, adapting to the situation that the distance between the mesial teeth and the distal teeth on both sides of the operation area is different in different operations.

Further, the two ends of the telescopic rod are respectively provided with a first end plate, and the first end plate is fixedly connected with the telescopic rod, and the end of the first clamper and the second clamper close to the telescopic rod are respectively connected with the second The end plates are fixedly connected, and the adjacent first end plates are rotatably connected to the second end plates through pin shafts.

The first end plate and the second end plate are used together, the position between the two telescopic rods is fixed, and relative rotation can occur between the first end plate and the second end plate, thereby making the first clamper and the second end plate The two holders can rotate relative to the telescopic rods respectively. When the mesial and distal teeth on both sides of the operation area are irregular, the telescopic rods on the buccal and lingual sides can evenly stretch the mucoperiosteal flap by rotating.

Working principle: When using this device, adjust the length of the telescopic rod according to the width of the planting area. If there is only one tooth in the planting area that needs to be planted, retract the protruding rod from the telescopic rod to the rod sleeve. Then fix the first clamper and the second clamper respectively on the tooth necks of the normal teeth on both sides of the surgical implant area. The first gripper is connected to the second gripper so that the telescoping rod passes through the surgical implant area and distracts the buccal and lingual mucoperiosteal flaps.

Beneficial effects of the present invention:

1) Use the first clamper and the second clamper together, so that the whole device can be fixed on both sides of the tooth area to be operated, and use the first clamper and the second clamper to place the normal teeth The buccal and lingual mucoperiosteal flaps in the area to be operated can be stretched apart by two telescopic rods, which do not need to be held by specialized medical staff after the surgical field of view is exposed.

2) The present invention can simplify the operation of implant surgery, liberate the hands of the operator, and use the expansion tool to replace the traditional manual stripping. After the bone-bond valve is expanded, the operation of the medical staff is no longer required, which saves manpower. The peeling of the lingual mucoperiosteal flap can be realized, and the implantation area can be fully exposed, which is conducive to the smooth progress of the implantation operation.

3) The telescopic rod can be stretched to change the distance between the first clamper and the second clamper, adapting to the situation that the distance between the mesial teeth and the distal teeth on both sides of the operation area is different in different operations.
