Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a soft tissue cutting guide plate. Background Technique

[0002] For the gingival recession around natural teeth and insufficient keratinized gingiva around implants, etc., it will cause periodontal and peri-implant inflammation, resulting in premature tooth loss and implant failure. Soft tissue transplantation is an effective solution to the above problems. Autologous free gingival graft taken from the hard palate is the gold standard for widening keratinized gingiva. At present, for the acquisition of keratinized gingiva in the hard palate, a surgical blade is commonly used for cutting, and a sheet of keratinized gingiva with a thickness of 1.5 mm × a width of 8 mm × a length of 10 - 30 mm is obtained. Since there is more bleeding during the acquisition of keratinized gingiva, which affects the surgeon's surgical field of vision, the thickness of the graft is the key to affecting the surgical effect.

[0003] In the existing surgical methods, doctors need to cut soft tissues according to the patient's condition. During the operation, the cutting range and depth are determined by experience. It is very difficult to control the cutting range and depth. If the cutting range is too large, the harm to the patient will increase. If the cutting is too shallow, the tissues cannot be separated, and the tissues do not meet the transplantation conditions. If the cutting depth is too deep, the graft will be too thick and will carry deep fat and glands, which often need to be removed, increasing the operation time and postoperative discomfort.

[0004] Therefore, the problems faced in the current clinical acquisition of hard palate keratinized gingiva are: 1. Poor vision and difficult operation; 2. Uneven thickness, affecting the postoperative effect; 3. Long operation time and large bleeding volume, increasing the postoperative discomfort of patients. For this reason, this application proposes a soft tissue cutting guide plate to provide a new technical solution to solve the above-mentioned technical problems. Content of the Utility Model

[0030] Embodiment 1:

[0031] Please refer toFigure 1 - Figure 2 , a soft tissue cutting guide, comprising: a guide body 1 and a scalpel 3;

[0032] The guide plate body 1 includes a plate body 11, on which a window hole 12 is opened, and the contour range of the window hole 12 is consistent with the range of soft tissue to be cut; further, in order to facilitate the fixation of the guide plate body 1, an adjacent tooth fixing part is provided on the plate body 11, and the plate body 11 is tightly fitted with the adjacent teeth through the adjacent tooth fixing part.

[0033] A stop assembly is provided on the side of the scalpel 3 near the tip of the scalpel 3 , and the distance from the tip of the scalpel 3 to the stop assembly is the thickness of the window hole 12 plus the thickness of the soft tissue to be cut.

[0034] When in use, the guide plate body 1 is first installed in the oral cavity 2, and the plate body 11 is ensured to be tightly matched with the adjacent tooth fixing part. The distance between the tip of the scalpel 3 and the stop assembly is the thickness of the window hole 12 plus the thickness of the soft tissue to be cut, wherein the thickness of the window hole 12 is set according to the cutting requirements to obtain the thickness of the soft tissue to be cut.

[0035] During use of the scalpel, the scalpel 3 always cuts along the contour of the window hole 12 .

[0036] The method for making the guide body 1 includes the following operations: photographing a patient's oral CT scan to obtain the patient's area to be transplanted and select a transplantation position, wherein the oral CT data has alveoli, tooth roots and crowns; obtaining model data of the patient's oral cavity, wherein the model has alveoli, tooth crowns and soft tissues; reconstructing a three-dimensional model of the patient's oral cavity, aligning the three-dimensional model data with the oral CT data, and obtaining a three-dimensional model of the oral cavity having alveoli, tooth crowns and soft tissues; determining the position of the soft tissue to be cut at the hard palate position according to the size and thickness of the soft tissue required in the area to be transplanted; the area to be cut of the soft tissue is generally rectangular, and the area extends outward in a layer thickness to form a model of the guide body 1.

[0037] Among them, digital software is used to simulate the precise position of soft tissue transplantation on three-dimensional software before transplantation.

[0038] Among them, the transplantation guide body 1 made by 3D printing can more accurately adapt the cut soft tissue to the transplant area, reduce the operation time, and the cut soft tissue is more accurate. It has the advantages of accurate positioning, precise cutting range and thickness, and can significantly improve the success rate of transplantation.

[0039] Embodiment 2:

[0040] The soft tissue cutting guide provided in Example 1 is further optimized. Specifically, Figures 3 - 4As shown in the figure, the stopping component includes a limiting member 31. The limiting member 31 is vertically slidably connected to the scalpel 3. One end of the limiting member 31 is rotatably connected with a moving small wheel 32, and the other end of the limiting member 31 is provided with a limiting knob 33 for moving and limiting.

[0041] Through the above structural design, before cutting, the position of the limiting member 31 is adjusted according to the cutting depth requirement, and the fixing of the limiting member 31 is realized by tightening the limiting knob 33. During cutting, the tip of the scalpel 3 is inserted into the window opening 12. By contacting the guide plate body 1 through the moving small wheel 32, the limiting of the insertion depth of the scalpel 3 is realized. The scalpel 3 always cuts along the contour of the window opening 12, and the resistance is reduced by the moving small wheel 32.
