[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1-Figure 7 As shown, a periodontal surgical tool assembly includes a handle body 7, which is a cylinder with a diameter of 1.0 cm. The upper part of the handle body 7 is connected to one end of an extended handle 8. An elastic plate 9 is provided on the upper surface of the extended handle 8. The elastic plate 9 is arranged longitudinally. The upper part of the elastic plate 9 is connected to the lower end of the tool body 3. The tool body 3 includes a blade 3a and a blade tip 3b. The blade 3a can be used for cutting, and the blade tip 3b can be used for stabbing, piercing and other operations.

[0025] In this embodiment, the upper edge of the blade body 3 is a blade 3a, and the end of the blade 3a is a blade tip 3b, so the blade body 3 has two blade tips 3b, and the operator does not need to constantly change the direction of holding the knife to achieve the purpose of piercing lesions at different positions. The cross section of the blade body 3 is an arc surface, the blade body 3 is horizontally arranged, and the blade body 3, the elastic plate 9, the extended handle 8, and the handle body 7 are formed as a whole and are vertically arranged. The contour of the blade body 3 is arranged axially symmetrically about the central axis of the elastic plate 9;

[0026] In this embodiment, two protrusions 3c are provided on the surface of the blade body 3, and the surface of the blade body 3 is connected to the extension rod 5a through the protrusions 3c. The lower part of the extension rod 5a is connected to the traction member 5b, and the end of the traction member 5b is an annular body. The whole formed by the two adjacent extension rods 5a and the traction member 5b is symmetrically arranged with respect to the whole formed by the handle body 7, the extension handle 8, and the elastic plate 9.

[0027] In this embodiment, two sheath portions 4 are provided on the surface of the extension handle 8, and the two adjacent sheath portions 4 are symmetrically arranged about the extension handle 8. The extension handle 8 fits tightly against the side of the sheath portion 4. A limiting groove 4a is provided inside the sheath portion 4. The limiting groove 4a is connected to the outside through the upper part and one of the side parts of the limiting groove 4a. The outer side surface of the inner wall of the limiting groove 4a is an arc surface, and a limiting block 4b is provided on the inner side of the bottom surface of the limiting groove 4a. The cross-section of the limiting block 4b is an arc-shaped contour, and the limiting block 4b is arranged longitudinally.

[0028] In this embodiment, the elastic plate 9 is deformed, and the upper part of the elastic plate 9 is biased toward one side of the overall central axis formed by the extended handle 8 and the handle body 7. The knife body 3 is deflected toward the same side, and the upper part of the extension rod 5a located on the other side is offset toward the same side. Due to the principle of rigid objects, the vertical distance from the annular body on the same side to the upper end of the extended handle 8 is h1, and the vertical distance from the annular body on the other side to the upper end of the extended handle 8 is h2, h1<h2. The operator can pull the two adjacent annular bodies, and due to the elastic deformation effect of the elastic plate 9, the knife body 3 is deflected, thereby changing the cutting angle of the blade 3a and the angle of the tip 3b, thereby increasing the diversity of cutting angles of oral surgical blades and the flexibility of cutting.

[0029] In this embodiment, the elastic plate 9 continues to deform, and the outer arc profile of the inner wall of the limiting groove 4a is concentrically arranged with the blade 3a, thereby reducing the friction between the blade body 3 and the inner wall of the limiting groove 4a. Part of the blade body 3 on the same side is located in the limiting groove 4a on the same side, so that the blade tip 3b on the same side is stuck on the inner side of the limiting block 4b, and the lower side of the blade tip 3b of the blade body 3 on the same side and the inner side surface of the limiting block 4b form a pre-tightening force. The line connecting two adjacent blade tips 3b is a vertical line, and the vertical line is located on one side. The pre-tightening force is offset by the elastic force of the elastic plate 9, so that the blade body 3 is fixed in the limiting groove 4a, which is convenient for the blade body 3 on the same side to be retracted into the limiting groove 4a of the sheath 4, thereby avoiding unnecessary cutting area and bleeding due to excessive area of ​​the blade tip 3b and the blade 3a that are not needed during operation.

[0030] In this embodiment, the flipping angle of the knife body 3 is adjusted and controlled by the elastic effect of the elastic plate 9, the traction piece 5b, and the overall traction effect formed by the extension rod 5a, so as to control the cutting angle and depth of the knife body 3, increase the diversity of the cutting angle of the oral surgical blade, increase the cutting flexibility, and facilitate the control of the cutting depth, and the surgical cutting has high accuracy. At the same time, the setting of the sheath 4 and the limit block 4b can make the knife body 3 after it is fully flipped, and the tip 3b is stuck in the limit groove 4a on the same side as the tip 3b, avoiding unnecessary cutting area and bleeding due to the excessive area of ​​the tip 3b and the blade 3a during operation, increasing the accuracy of surgical cutting, and ensuring the smooth implementation of periodontal surgery.

[0031] In this embodiment, the blade body 3 is made of stainless steel, the limit block 4b is made of hard silicone, the thickness of the middle part of the blade body 3 is 1.8mm-2.5mm, the angle of the blade 3a is 18°~25°, the width of the blade body 3 is 0.5cm~1.5cm, and the upper part of the extension rod 5a is a deformable structure to ensure that when the annular body is pulled longitudinally at one end, the upper part of the extension rod 5a at the other end is passively deformed to ensure the overall stability of the device.

[0032] The working process of this embodiment is as follows:

[0033] S1: The palm of the hand is against the lower end of the handle body 7, and the index finger and thumb respectively control the two adjacent annular bodies. The thumb longitudinally pulls the annular body on one side, and the knife body 3 deflects to one side due to the elastic effect of the elastic plate 9. The index finger assists in controlling the annular body on the other side to keep the knife body 3 in a stable state. At this time, the annular body controlled by the thumb is in a state away from the upper end of the extended handle 8, and the annular body controlled by the index finger is in a state close to the upper end of the extended handle 8, and the knife body 3 is in a fixed state; the thumb relaxes and pulls the annular body on one side, and the knife body 3 rebounds due to the elastic effect of the elastic plate 9. The index finger pulls the annular body on the other side longitudinally, and the knife body 3 deflects to the other side due to the elastic effect of the elastic plate 9. The thumb fixes the annular body on one side to keep the knife body 3 in a stable state. At this time, the annular body controlled by the thumb is close to the upper end of the extension handle 8, and the annular body controlled by the index finger is away from the upper end of the extension handle 8. The knife body 3 is in a fixed state. The flipping angle of the knife body 3 is controlled by controlling the distance between the two adjacent annular bodies and the upper end of the extension handle 8, so as to achieve the purpose of flexibly changing the cutting angle and increasing the accuracy of surgical cutting.

[0034] S1: The flipping angle of the knife body 3 is controlled by controlling the distance between the two adjacent annular bodies and the upper end of the extension handle 8, so that the highest point in the middle of the blade 3a is parallel to the target tissue to be cut. The flipping angle of the knife body 3 is controlled by controlling the distance between the two adjacent annular bodies and the upper end of the extension handle 8. With the target tissue as the midpoint, the flipping angles are in the same angle and reverse state, so as to achieve the purpose of controlling the cutting depth, increasing the accuracy of surgical cutting, and reducing unnecessary cutting area and bleeding.

[0035] S3: Pull the annular body on one side longitudinally to retract part of the blade body 3 into the limiting groove 4a in the sheath 4 on this side. The line connecting the two adjacent blade tips 3b is a vertical line, which is located on one side. The blade tip 3b of the part of the blade body 3 retracted into the limiting groove 4a is against the outer side of the limiting block 4b. Slightly relax the annular body so that the blade tip 3b is located above the limiting block 4b. Pull the annular body on one side inward so that the blade tip 3b passes over the highest point of the limiting block 4b. Stop applying the traction force. The lower part of the blade tip 3b is limited to the inner upper surface of the limiting block 4b due to the rebound effect of the elastic plate 9. At the same time, assist in controlling the annular body on the other side to keep the blade 3 in a stable state, so that part of the blade body 3 is fixed in the limiting groove 4a, which is convenient for retracting part of the blade body 3 into the limiting groove 4a of the sheath 4 to avoid unnecessary cutting area and bleeding due to excessive area of ​​the blade tip 3b and blade 3a during operation.
