Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, and in particular to an intraoral gingival flap minimally invasive incision pulling device. BACKGROUND

[0002] Mandibular impacted wisdom tooth extraction is the most widely used treatment for mandibular impacted wisdom teeth. Due to the variable position of the mandibular impacted wisdom teeth, it is often embedded under the bone and under the mucosa. This surgery often requires the steps of turning up the gingival flap, removing the impacted bone, and cutting the tooth with a turbine drill to remove the tooth. The turning up of the gingival flap is the key to determining and exposing the surgical field, and the gingival flap needs to be kept turned up during the operation to ensure a clear surgical field. Insufficient turning up of the gingival flap can greatly increase the difficulty of the operation.

[0003] Currently, there is no special instrument for maintaining the turned-up gingival flap. Clinically, doctors often hold and use a periosteal elevator with their left hand to maintain the turned-up gingival flap. However, when the end of the periosteal elevator is used to maintain the turned-up gingival flap, the middle part of the instrument must also be used to pull open the patient's cheek, causing the surgeon's left hand to be in a fatigue state for a long time during the operation, causing tendinitis and other occupational diseases. Although there are specialized flap turning instruments in related technologies, they must be operated by another dedicated assistant who is in perfect coordination with the surgeon, which can lead to a waste of human resources. SUMMARY

[0004] The intraoral gingival flap minimally invasive incision pulling device of the utility model improves the difficulty of maintaining the turned-up state of the gingival flap in the prior art, can independently maintain the turned-up state of the gingival flap during the operation, and reduces the difficulty of the operation.

[0005] To achieve the above-mentioned purpose, the utility model provides an intraoral gingival flap minimally invasive incision pulling device, which comprises:

[0006] Two clamping arms, the two clamping arms are arranged in parallel;

[0007] A spring piece, the two ends of the spring piece are connected to the two clamping arms, respectively;

[0008] A cantilever, the cantilever is connected to one of the two clamping arms, and the cantilever extends along the line connecting the spring piece to the clamping arm. The cantilever is provided with a wing portion. In use, according to the surgical requirements, the gingival flap is designed and turned up, the two clamping arms are spread apart and clamped on both sides of the adjacent tooth of the wisdom tooth, the cantilever is close to the turned-up gingival flap, and the wing portion is used to block the gingival flap to prevent the gingival flap from rebounding. After the pulling device is installed, it can independently prevent the gingival flap from rebounding and maintain the turned-up state of the gingival flap, without the need for the operating surgeon or the assistant to continuously operate, which helps to reduce the difficulty of the operation.

[0009] As an optional technical solution, the clamping arm comprises a first surface, a line between the two clamping arms is parallel to the first surface, and / or the first surface has a tangent line parallel to the line between the two clamping arms, and the elastic sheet is arched towards a direction away from the first surface. In use, the first surface faces the direction of the patient's tooth crown, the elastic sheet is arched towards the tooth crown, and the space formed by the arching of the elastic sheet can avoid other teeth, thereby facilitating the installation of the retractor.

[0010] As an optional technical solution, the wing part comprises a distal wing and a mesial wing, the distal wing is arranged at the end of the cantilever and is located on the same side as the first surface and the arching direction of the elastic sheet, the mesial wing is arranged on the side of the cantilever away from the distal wing. The current mainstream surgical method for mandibular impacted wisdom tooth flap is the envelope flap and the distal triangular flap. The characteristics of these two surgical methods are that the distal side and the mesial side of the wisdom tooth have gum flaps that need to be turned up. The distal wing blocks the turning back of the distal side gum flap of the wisdom tooth, and the mesial wing blocks the turning back of the mesial side gum flap of the wisdom tooth, thereby keeping the surgical field clear.

[0011] As an optional technical solution, the end of the cantilever is curved to form the distal wing on the side away from the mesial wing, and the curved part is circularly transitioned. The distal wing is close to the end of the cantilever, and the circular transition at this position is beneficial to reduce the possibility of accidental injury to the patient caused by the retractor.

[0012] As an optional technical solution, the clamping arm is provided with a mounting hole, and the mounting hole penetrates the clamping arm in the thickness direction of the clamping arm. During the operation, the surgeon can use the surgical instrument to penetrate the mounting hole to spread the two clamping arms, thereby installing the retractor in place.

[0013] As an optional technical solution, the diameter of the mounting hole is greater than 1.8 mm and less than 2.2 mm, and the line connecting the centers of the two mounting holes is perpendicular to the extension direction of the clamping arm. The diameter of the mounting hole in this range can make the clamping part of the rubber barrier clamp sub enter, without the need to use special instruments, which is beneficial to reduce the preparation difficulty and use cost of surgical instruments.

[0014] As an optional technical solution, the clamping arm comprises a fixing surface, and the fixing surfaces of the two clamping arms are oppositely arranged. The two fixing surfaces are concave on the opposite sides, so that the fixing surface better fits the surface of the clamped tooth, and the fixation of the retractor is more stable.

[0015] As an optional technical scheme, the fixed surface is protruded to form a beak part along two sides of the extending direction of the clamping arm, and the beak part is used for clamping the tooth neck.

[0016] As an optional technical scheme, a plurality of tooth-shaped protrusions are arranged on the fixed surface, and the tooth-shaped protrusions can increase the friction between the fixed surface and the clamped tooth surface, thereby improving the fixing effect of the retractor.

[0017] As an optional technical scheme, the two clamping arms, the elastic sheet and the cantilever are integrally formed, which facilitates the manufacturing of the retractor and is beneficial to reduce the cost of the retractor.

[0018] The one or more technical schemes of the utility model have at least the following technical effects or advantages:

[0019] The intraoral gingival flap minimally invasive incision retractor is characterized in that two clamping arms are arranged in parallel, one end of the two clamping arms is connected to the elastic sheet, and the cantilever with the wing part is arranged to connect one of the two clamping arms, the two clamping arms are opened and clamped on both sides of the adjacent tooth of the wisdom tooth, the cantilever is close to the opened gingival flap, the wing part is used to block the gingival flap, and the gingival flap is prevented from rebounding.
