Description

Technical Field

[0001] The present invention relates to the technical field of dental treatment, and more particularly to a periosteal stripper. Background Art

[0002] A periosteal separator is an instrument used in dental surgery, mainly used to peel off the periosteum on the surface of bones. The periosteum is a thin film covering the surface of bones, which has the function of protecting and nourishing bones. Specifically, a periosteal separator usually consists of a flat, round or oval head and a flexible handle. During the dental implant surgery, the doctor inserts the periosteal separator near the implant location to be implanted and presses the head on the bone surface. Then, the doctor applies force to the handle to pull the head apart and peel off the periosteum. This process can help doctors better control the location and depth of implant placement and provide patients with better tooth support. In dental surgery, the working principle of the periosteal separator is to peel off the periosteum from the bone surface, separate the gums and bone tissue, to expose and prepare the implant location, and facilitate the subsequent implant placement.

[0003] When the current dental periosteal separator is in use, the gums and soft tissues have good elasticity when the blade part is cutting the gums and soft tissues. During the cutting from shallow to deep, the cut gums and soft tissues will re-cover the top of the blade of the periosteal separator, thereby affecting the doctor's accurate judgment of the blade position and causing blind spots during the operation. Therefore, the doctor needs additional auxiliary instruments to push aside the cut soft tissues and gums to ensure that subsequent surgical cutting operations can be carried out. The overall operation process is too complicated, and after the blind spots are generated, additional instruments are required for auxiliary operations, which increases the difficulty and risk of the operation. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a periosteal stripper, which is provided with an arc surface A, an arc surface B and an arc block. When the blade part cuts from shallow to deep, the cut gums and soft tissue parts will cover the arc block above the blade head, and the gums and soft tissue parts will be pushed away to the outside of the cutting direction through the arc surface A and the arc surface B, thereby maximizing the doctor's observation field of view and ensuring that the doctor can accurately judge the position of the blade head, thereby improving the safety of the operation and solving the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a periosteal stripper, comprising a periosteal separator, wherein the left and right ends of the periosteal separator are respectively provided with a handle and a blade head, the overall posture of the blade head is maintained in a curved state with the periosteal separator, and the back of the blade head is provided with an arc block;

[0006] The overall posture of the arc block is consistent with the outer inclination of the blade head. The arc block includes a fixed block. The upper and lower sides of the outer edge of the fixed block are respectively provided with an arc surface A and an arc surface B. There are two arc blocks, which are symmetrically distributed on the left and right sides of the back of the blade head, and the tail ends of the two arc blocks are kept connected, so as to form a V shape together. Through the above arrangement, the pair of V-shaped arc blocks can be used to move the cut gums and soft tissue parts to the left and right sides, thereby ensuring that the doctor can directly observe the main part of the blade head, thereby improving the safety and accuracy of the device during surgery;

[0007] The arc surface A and the arc surface B together form an arc structure protruding outward, and the volume of the arc structure gradually increases from the arc surface A to the arc surface B. The outer edge trajectories of the arc surface A and the arc surface B are segment A and segment B respectively. The overall curvature of segment A is smaller than the overall curvature of segment B, and the overall length of segment A is greater than the overall length of segment B. The arc surface A is spaced apart from the farthest end of the tool head, and the tail end of the arc surface B extends to the connection position of the curved part and the straight part of the tool head. The tool head and the arc surface A satisfy the following rule: make a horizontal extension line parallel to and overlapping with the outside of the tool head, and the extension line remains tangent to the arc midpoint of the arc surface A.

[0008] In a preferred embodiment, a rounded corner is provided at a connection portion of the periosteal separator close to the cutting head.

[0009] In a preferred embodiment, the periosteal separator is made of medical-grade materials throughout, and the periosteal separator is flat as a whole.

[0010] In a preferred embodiment, the entire outer side of the arc block is designed with rounded corners, and the entire surface of the arc block is smooth.

[0011] In a preferred embodiment, the outer side of the fixing block close to the cutter head is adapted to the shape of the cutter head, and the arc block is a shuttle-shaped structure with small ends and a large middle part when viewed from above.

[0012] Technical effects and advantages of the present invention:

[0013] The present invention provides an arc surface A, an arc surface B and an arc block, and utilizes the mutual cooperation of the arc surface A, an arc surface B and an arc block. When the blade head cuts from shallow to deep, the cut gums and soft tissue parts will cover the arc block above the blade head, and the gums and soft tissue parts will be pushed outward in the cutting direction by the arc surface A and the arc surface B, so as to maximize the doctor's observation field of view and ensure that the doctor can accurately judge the position of the blade head, thereby improving the safety of the operation.

[0014] In the process of continuous and deep cutting, the overall curvature of section A is smaller than that of section B, and the volume of the arc structure gradually increases from the side of arc surface A to the side of arc surface B. This allows the distance and angle of the cut gums and soft tissues to be peeled off to the outside of the cutting direction to gradually increase, thereby further improving the angle range of the blade when cutting deeply, thereby further improving the use effect of the device.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] As attached Figure 1 To Attachment Fig.10 A periosteal stripper shown includes a periosteal separator 1, wherein a handle 2 and a blade 3 are respectively provided at the left and right ends of the periosteal separator 1, wherein the overall posture of the blade 3 is maintained in a bent state with the periosteal separator 1, and an arc block 4 is provided on the back of the blade 3;

[0028] The overall posture of the arc block 4 is consistent with the outer inclination of the blade head 3. The arc block 4 includes a fixed block 41. The upper and lower sides of the outer edge of the fixed block 41 are respectively provided with an arc surface A42 and an arc surface B43. There are two arc blocks 4, which are symmetrically distributed on the left and right sides of the back of the blade head 3, and the tail ends of the two arc blocks 4 are kept connected, so as to form a V shape together. Through the above arrangement, the pair of V-shaped arc blocks 4 can be used to move the cut gums and soft tissue parts to the left and right sides, thereby ensuring that the doctor can directly observe the main part of the blade head 3, thereby improving the safety and accuracy of the device during surgery;

[0029] The arc surface A42 and the arc surface B43 together form an arc structure protruding outward, and the volume of the arc structure gradually increases from the arc surface A42 to the arc surface B43. The outer edge tracks of the arc surface A42 and the arc surface B43 are segment A and segment B respectively. The overall curvature of segment A is smaller than the overall curvature of segment B, and the overall length of segment A is greater than the overall length of segment B. The arc surface A42 is spaced apart from the farthest end of the cutter head 3. The tail end of the arc surface B43 extends to the connection position of the curved part and the straight part of the cutter head 3. The following rules are satisfied between the cutter head 3 and the arc surface A42: make a line parallel to and overlapping with the cutter head 3. The horizontal extension line of the outer side of the head 3 is tangent to the arc midpoint of the arc surface A42. Through the above-mentioned setting, the tangent design between the blade head 3 and the arc surface A42 is utilized to ensure that when the blade head 3 peels off the gum or soft tissue part, the peeled gum or soft tissue part can slide smoothly and unimpeded to the surface of the arc surface A42, and then be gradually pushed outward by the arc surface A42, and continue to peel outward along the arc surface B43 at the bottom of the arc surface A42, which further complies with the unobstructed operation in the operation, ensures the doctor's operating line of sight is unobstructed, thereby ensuring the accuracy of the doctor when cutting deeply, and further improving the safety in the periosteal stripping operation.

[0030] The periosteal separator 1 is provided with a rounded corner 5 at a connection point on one side close to the blade head 3, the outer side of the arc block 4 is designed with rounded corners, and the entire surface of the arc block 4 is smooth.

[0031] For details, please refer to the attached manual Figure 1 The periosteal separator 1 is made of medical-grade materials throughout, and the periosteal separator 1 is flat as a whole.

[0032] The specific implementation method is: utilizing the special material design of the periosteal separator 1 to make it meet the medical sterility standard, thereby providing basic safety guarantee for the stripping operation, and at the same time setting the whole device to be flat, which is more convenient for doctors to operate.

[0033] For details, please refer to the attached manual Figure 3 and attached Figure 7 The fixing block 41 is close to the outer side of the cutter head 3 and is adapted to the shape of the cutter head 3. The arc block 4 is a shuttle-shaped structure with small ends and a large middle part when viewed from above.

[0034] The specific implementation method is as follows: the arc block 4 is set in a shuttle-shaped structure from a top-down perspective to maximize the reduction of the overall volume distribution of the arc block 4, thereby effectively spreading the cut gums and soft tissue parts outward while ensuring that the overall volume of the arc block 4 is small, thereby maximizing the doctor's observation field of view, accurately judging the position of the blade head 3, and providing a safer operating posture for the operation.

[0035] Working principle of the present invention:

[0036] Step 1: First, the operating physician visually inspects the various components of the device, and then uses the device normally to perform the dental implant surgery.

[0037] Step 2: First, the doctor uses the blade 3 on the periosteal separator 1 to peel off the patient's gums and soft tissue from the bone.

At the same time, the horizontal extension line of the outer side of the blade 3 is kept tangent to the arc midpoint of the arc surface A42, so as to ensure that when the blade 3 peels off the gums or soft tissue, the peeled gums or soft tissue can slide smoothly to the surface of the arc surface A42, and be gradually pushed outward by the arc surface A42, and then continue to peel outward along the arc surface B43 at the bottom of the arc surface A42, to ensure that the entire process The process conforms to the unobstructed operation during the operation, maximizes the doctor's observation field of view, and ensures that the doctor can accurately judge the position of the blade 3, thereby improving the safety of the operation. In the process of continuous and deep cutting, the overall curvature of section A is smaller than the overall curvature of section B, and the volume of the arc structure gradually increases from the side of the arc surface A42 to the side of the arc surface B43, so that the distance and angle of the cut gums and soft tissues peeled outward in the cutting direction are gradually increased, thereby further improving the angle range of the blade 3 that the doctor can directly observe during deep cutting, and further improving the use effect of the device. Finally, the device completes the operation of separating the gums and bone tissues of the patient's gums, and provides position preparation for the subsequent implantation, which is convenient for the subsequent implantation.

[0038] Step 3: First, the operator shuts down the device normally, then checks whether the fixation between the various components of the device is normal, and then replaces and repairs the aging and severely worn parts inside the device.
