Description

Technical Field

[0001] This invention relates to the field of dental implantation, and in particular to a free connective tissue clamping and suturing guide. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] During anterior tooth implantation, in order to better protect the underlying bone remodeling or increase the fullness of the soft tissue, it is necessary to increase the thickness of the labial soft tissue.

[0004] The clinically accepted procedure is as follows: a soft tissue envelope is prepared on the labial side of the implantation site in the recipient area. After free deepithelialized connective tissue is harvested from the maxillary palate of the donor area, it is sutured into the soft tissue envelope in the recipient area using a horizontal double mattress suture method.

[0005] The inventors discovered the following main problems during clinical procedures:

[0006] (1) Free connective tissue is slippery and is currently mainly held by simple tweezers. However, free connective tissue is not easy to be clamped and stabilized by tweezers. When sutures are needed before dental implantation, the suture needle is easy to slip and fall off during the process of entering and exiting, which increases the difficulty of suturing and requires a long time.

[0007] (2) Because free connective tissue is not easy to be clamped and fixed, the operator is likely to use a large force to clamp the free connective tissue and continue to apply force, which can easily apply too much pressure to the free connective tissue.

[0008] The inventors also discovered the following problems in the existing operation:

[0009] (3) For operators with limited surgical skills, the double mattress suture method requires 8 needle insertions and exits to fix the two layers of tissue together. Because of the large number of needle insertions and exits and the difficulty in controlling the needle insertion and exit positions, a series of problems such as long chairside time during the operation, long exposure time of free connective tissue, and poor placement of free connective tissue are caused, thus affecting the soft tissue augmentation effect.

[0010] (4) Currently, assistants use forceps on the opposite side of the surgeon to hold free connective tissue, but the structure of commonly used forceps is limited, making it inconvenient for assistants to use them on the opposite side of the surgeon. Summary of the Invention

[0011] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a free connective tissue clamping and suturing guide that ensures stable clamping of free connective tissue without applying excessive pressure to the free connective tissue.

[0012] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0013] A free connective tissue clamping and suturing guide includes a clamping component, which includes two clamping parts connected at one end and with an adjustable angle between them. A limiting member is provided on the inner side of the clamping parts. A first support portion is provided at the free end of one clamping part, and a second support portion is provided at the free end of the other clamping part. The first support portion has a first opening and a second opening, and a connecting channel is provided between the first opening and the second opening. The second support portion has a third opening and a fourth opening, which are respectively connected to the side of the second support portion. When the clamping component clamps the free connective tissue, the positions of the first opening and the third opening, and the second opening and the fourth opening correspond.

[0014] As described above, in a free connective tissue clamping and suturing guide, the positional correspondence between the first and third openings, and the second and fourth openings of the clamping component when clamping the free connective tissue refers to the following: when the clamping component clamps the free connective tissue, and the first support portion is projected onto the second support portion, the first and third openings partially or completely overlap, and the second and fourth openings partially or completely overlap.

[0015] As described above, in a free connective tissue clamping and suturing guide, the corresponding positions of the first and third openings, and the second and fourth openings of the clamping component when clamping the free connective tissue refer to the following: when the clamping component clamps the free connective tissue, the central axes of the first and third openings coincide, and the central axes of the second and fourth openings coincide.

[0016] As described above, a free connective tissue clamping and suturing guide has a first support portion provided with two first openings and two second openings, with a predetermined distance between the two first openings;

[0017] The distance between the two first openings is the same as the distance between the two second openings;

[0018] As described above, in a free connective tissue clamping and suturing guide, the second support portion is provided with two third openings and two fourth openings, with a set distance between the two third openings and a set distance between the two fourth openings;

[0019] The distance between the two third openings is the same as the distance between the two fourth openings;

[0020] The distance between the two third openings is the same as the distance between the two first openings.

[0021] As described above, in a free connective tissue clamping and suturing guide, all the first openings and second openings form the four corners of a rectangle;

[0022] All of the aforementioned third and fourth openings form the four corners of a rectangle.

[0023] As described above, in a free connective tissue clamping and suturing guide, the distance between the two first openings is 5mm-7mm;

[0024] The distance between the first opening and the second opening is 4mm-6mm.

[0025] As described above, a free connective tissue clamping and suturing guide has a first support portion with a predetermined length and width, and a second support portion with a predetermined length and width, thereby having a predetermined area for both the first and second support portions, further ensuring stable clamping of the free connective tissue.

[0026] As described above, a free connective tissue clamping and suturing guide has one end of each of the two clamping members fixed, and the other end of the clamping members bent, with the bent end of the clamping member fixed to the first support or the second support.

[0027] The bending angle at the bend of the clamping part is 90°-120°.

[0028] As described above, in a free connective tissue clamping and suturing guide, the width of the connecting channel is smaller than the diameter or width of the first opening;

[0029] The second support part is provided with connecting grooves on one side of the third opening and the fourth opening, and the connecting groove at the third opening and the connecting groove at the fourth opening are perpendicular to each other.

[0030] As described above, a free connective tissue clamping and suturing guide is provided, wherein the limiting member is a limiting rod fixed to the inner side of the clamping member, and the free end of the limiting rod is provided with a hook, and the hooks of the limiting members on both sides can be fastened together;

[0031] After the two limiting parts are engaged, the first support part and the second support part are parallel to each other, and the distance between the first support part and the second support part is 1.45mm-1.6mm.

[0032] The beneficial effects of the present invention are as follows:

[0033] 1) In this invention, the clamping component clamps the free connective tissue through the first support and the second support, which can achieve stable clamping of the free connective tissue and prevent it from falling off. The clamping component is provided with a limiting component on the inner side to ensure the opening and closing angle of the clamping component, so as to ensure that the clamping force avoids excessive compression while stably clamping the free connective tissue. The first opening, the second opening, the third opening and the fourth opening facilitate the suturing of the free connective tissue and the surface tissue, and avoid the free connective tissue being exposed for too long. The connection channel and the third opening and the fourth opening are connected to the end side to ensure that the first support and the second support can be removed after suturing.

[0034] 2) The present invention provides two first openings, two second openings, two third openings and two fourth openings. A connecting channel is provided between the first openings and the second openings. The third openings and the fourth openings are connected to the side of the second support. The first support can support the surface tissue, thereby guiding the completion of double horizontal mattress sutures and ensuring smooth withdrawal after suturing. Even beginners can complete the suturing relatively quickly.

[0035] 3) The present invention further ensures stable clamping of free connective tissue by having a set length and width for both the first support part and the second support part, and a set area for both the first support part and the second support part.

[0036] 4) In this invention, one end of the clamping member is bent, and the bent end of the clamping member is connected to the first support part and the second support part, which facilitates the clamping operation by the operator at the opposite side of the surgeon. Attached Figure Description

[0046] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0047] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0048] For ease of description, the words "up," "down," "left," and "right" appearing in this invention only indicate that they are consistent with the up, down, left, and right directions of the accompanying drawings themselves, and do not limit the structure. They are merely for the purpose of facilitating the description of this invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0049] Terminology Explanation: The terms "installation," "connection," "linking," and "fixing" in this invention should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction relationship between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0050] As described in the background section, there is a problem with the unstable clamping of free connective tissue in the prior art. In order to solve the above technical problem, the present invention proposes a free connective tissue clamping and suturing guide.

[0051] In a typical embodiment of the present invention, reference is made to Figure 1 As shown, a free connective tissue clamping and suturing guide includes a clamping component, which includes two clamping parts 3. One end of the two clamping parts 3 is connected and the angle between them is adjustable. A limiting part 4 is provided on the inner side of the clamping parts 3. A first support part 1 is provided on the free end of one clamping part 3, and a second support part 2 is provided on the free end of the other clamping part. The first support part is provided with a first opening and a second opening. A connecting channel 1-1 is provided between the first opening and the second opening. The second support part is provided with a third opening and a fourth opening. The third opening and the fourth opening are respectively connected to the side of the second support part. When the clamping component clamps the free connective tissue, the positions of the first opening and the third opening, and the second opening and the fourth opening are corresponding.

[0052] When the clamping component clamps free connective tissue, the positions of the first opening and the third opening, and the second opening and the fourth opening correspond to each other. This means that when the clamping component clamps free connective tissue, when the first support is projected onto the second support, the first opening and the third opening partially or completely overlap, and the second opening and the fourth opening partially or completely overlap. As long as they partially overlap, it is sufficient to ensure that the suture needle can pass through.

[0053] In this embodiment, the correspondence between the first and third openings, and the second and fourth openings when the clamping component clamps free connective tissue means that when the clamping component clamps free connective tissue, the central axes of the first and third openings coincide, and the central axes of the second and fourth openings coincide, further ensuring that the suture needle passes through each opening.

[0054] refer to Figure 2 As shown, the first support part 1 is provided with two first openings B and G and two second openings C and F. The two first openings B and G are spaced apart by a predetermined distance, and the two first openings C and F are also spaced apart by a predetermined distance. The distance between the two first openings is the same as the distance between the two second openings. (Reference) Figure 3 As shown, the second support part 2 is provided with two third openings A and H and two fourth openings D and E. The two third openings A and H are spaced apart by a set distance, and the two fourth openings D and E are spaced apart by a set distance.

[0055] The distance between the two third openings is the same as the distance between the two fourth openings; the distance between the two third openings is the same as the distance between the two first openings.

[0056] Thus, all the first and second openings form the four corners of the rectangle; all the third and fourth openings form the four corners of the rectangle. It can be understood that the two rectangles of the first and second support parts have the same length and the same width.

[0057] Specifically, the first, second, third, and fourth openings are all round holes. Of course, in some examples, the first, second, third, and fourth openings can also be rectangular holes.

[0058] Considering the need to guide the completion of double-level mattress sutures, the distance between the two first openings is 5mm-7mm, preferably 6mm; the distance between the first opening and the second opening is 4mm-6mm, preferably 5mm. These two values ​​meet the requirements for suturing and fixing free connective tissue in a single tooth position in the anterior region.

[0059] In addition, the first support part 1 and the second support part 2 are provided with anti-slip texture on the side for clamping the free connective tissue 6, which can increase the stability of clamping the free connective tissue. Even without fastening the clamping parts, the free connective tissue can be stably clamped. Even if it is not used for double-level mattress-type guided suturing, it can be used for clamping free connective tissue in daily life, thus expanding the application range.

[0060] To stably hold the free connective tissue, the first support 1 has a set length and width, and the second support 2 has a set length and width, thus the first support and the second support have a set area, further ensuring the stable holding of the free connective tissue; specifically, the first support and the second support are both plate-shaped, and specifically, the first support and the second support have the same length and the same width, and their length * width is 10 * 8 mm, which is the same size as the free connective tissue commonly used in clinical single teeth.

[0061] In this embodiment, the side of the second support 2 is engraved with scale lines to facilitate the determination of the size of the free connective tissue and the position of the needle within the free connective tissue during the operation.

[0062] In addition, to facilitate beginners in quickly and easily using the clamping suture guide, the positions of the corresponding openings on the surfaces of the first and second support parts are marked A, B, C, D, E, F, G, and H respectively, according to the order of suture needle entry and exit.

[0063] Regarding the clamping components, one end of each clamping component 3 is fixed, and the other end of the clamping component 3 is bent. The bent end of the clamping component is fixed to the first support or the second support. The bending angle of the clamping component is 90°-120°.

[0064] refer to Figure 1 and Figure 5As shown, the clamping member 3 includes a first segment 5-1, a second segment 5-2, and a third segment 5-3. The first segment is the fixed segment of the two clamping members. The second segment has a longer length, which is greater than the length of the first and third segments. The bending angle between the second and third segments is 90°-120°, preferably 110°. Moreover, the second and third segments have a smooth transition. The third segment is connected to the first or second support part. The length direction of the third segment is perpendicular to that of the first support part, which makes it convenient for the operator to hold the clamp from the opposite side of the operator.

[0065] Additionally, it should be explained that the width of the connecting channel is less than the diameter or width of the first opening, and the connecting channels between the first and second openings on both sides are parallel to each other.

[0066] The second support part has a connecting groove 2-1 on one side of the third opening and the fourth opening, respectively. The width of the connecting groove 2-1 is smaller than the diameter or width of the third opening or the fourth opening. The connecting groove at the third opening and the connecting groove at the fourth opening are perpendicular to each other. The connecting grooves of the two third openings connect to the same side of the second support part, so the connecting grooves of the two third openings are parallel to each other. The connecting grooves of the two fourth openings are located on the same straight line. The sides connected by the connecting grooves of the two fourth openings are the two opposite sides of the second support part.

[0067] In this embodiment, the limiting member 4 is a limiting rod fixed to the inner side of the clamping member. One end of the limiting rod is fixed to the inner side of the clamping member, and the other end is provided with a hook. The limiting rods on both sides are staggered and the hooks of the limiting members on both sides can be fastened. When using the device, the operator can fasten the two limiting members. The operator does not need to exert continuous force during the gripping process, and the gripping stability is increased.

[0068] After the two limiting parts 4 are engaged, the first support part 1 and the second support part 2 are parallel to each other, and the distance between the first support part and the second support part is 1.45mm-1.6mm. Optimally, the distance between the first support part and the second support part after engagement is 1.5mm. This dimension is the commonly used thickness of free connective tissue, avoiding excessive pressure on the free connective tissue. If the thickness of the free connective tissue obtained clinically is greater than 1.5mm, the operator can choose not to engage the two limiting parts. Because the free connective tissue is thicker, the inner sides of the first support part and the second support part used to clamp the free connective tissue are provided with anti-slip textures, which can also achieve stable clamping of the free connective tissue.

[0069] refer to Figure 4As shown, the first support and the second support clamp the free connective tissue 6, with the second support on top and the first support on the bottom. The upper part of the second support supports the surface tissue 5. The suture needle with thread passes through the surface tissue, the third opening A, the free connective tissue, the first opening B, the second opening C, the free connective tissue, the fourth opening D, the surface tissue (the surface tissue at the envelope), (after the suture needle moves horizontally a set distance) the surface tissue, the fourth opening E, the free connective tissue, the second opening F, the first opening G, the free connective tissue, the first opening H, and the surface tissue after suturing. After suturing, because the first support has a connecting channel and the second support has a connecting groove, it is extremely convenient to remove the first support and the second support. At the same time, it is easy to position the free connective tissue in the envelope. It can achieve stable clamping of the free connective tissue during the suturing and positioning process, effectively avoid the free connective tissue being exposed for too long, and facilitate the surgeon's clamping operation on the opposite side. It can guide the completion of double-level mattress sutures more quickly and shorten the chairside time during the operation.

[0070] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
