Description

Technical Field

[0001] The utility model belongs to the technical field of dental surgical knives, and in particular relates to a knife for transversely cutting gum subcutaneous tissue. Background Art

[0002] In the field of dental technology, after a patient has a tooth extracted, a wound will be left in the extraction socket, and a blood clot will form at the wound. Over time, the blood clot will gradually decompose and be absorbed. At the same time, the new cells at the wound will continue to proliferate, forming new tissues and eventually healing. Due to the loss of teeth, after healing, the gums shrink, the upper end of the gums shrinks and is not conducive to later dental implants. During later dental implants, the missing teeth are restored by implanting artificial roots and then fixing the crowns, but the atrophied gums are not conducive to grooving and operation. In the process of grooving the gums, first a vertical groove needs to be opened at the top of the gums, and then grooves are made horizontally on both sides and the epidermis at the top of the gums is retained. The thickness of the epidermis should be kept consistent as much as possible. When grooving the inner gingival epidermis, the operating space of the gum knife is relatively large. When grooving the outer gingival epidermis, the operating space of the gum knife is narrower, which is very inconvenient to operate.

[0003] The current gum knife mainly has the following structures, one of which is as follows Figure 6 The axe-shaped gum knife shown in the figure has a blade on one side, and the blade and the handle are arranged on the same vertical plane, with a certain inclination angle between the blade and the handle; another structure is as shown in the figure Figure 7 The pointed-blade gum knife shown in the figure has blades on both sides, and the blade and handle are arranged on the same vertical plane; these two structures are the most common structures at present, and other gum knife structures are not much different from these two structures. The blade and handle of these structures are arranged on the same vertical plane. After the blade makes a vertical groove, it continues to make a horizontal groove. Due to the limitations of the oral space and the blade structure, the blade cannot make a horizontal groove horizontally. If the horizontal groove width is large, the inclined blade will easily cut the epidermis at the top of the gum, causing damage to the gum epidermis, which is not conducive to the subsequent dental implant operation. Utility Model Content

[0004] In order to solve the technical problems existing in the prior art, the utility model provides a gum transplant cutting device, which is convenient for dentists to make transverse grooves on atrophic gums in a limited oral space, and has easy operation and good flexibility.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a gingival transplant cutting device, including a handle, one end of the handle is connected to one end of a first transition connecting rod, and the other end of the first transition connecting rod is connected to the first cutting head through a guide connecting rod.

[0006] The first transition link is smoothly connected to the guide link, the central axis of the knife handle overlaps with the central axis of the first transition link, the central axis of the first transition link and the central axis of the guide link are arranged at an angle of 30°-60°, the first knife head is vertically arranged on the side of the guide link, and the tip of the first knife head extends outward. When the doctor holds the knife handle to operate, the first knife head enters the oral cavity obliquely downward, and the inclined guide link structure can make it more convenient for the doctor to operate.

[0007] After the inner gingival epidermis is vertically grooved, the transverse groove can be facilitated by the transversely arranged first blade head. The transversely arranged first blade head moves horizontally and will not scratch the epidermis at the top of the transverse groove, thereby avoiding damage to the gingival epidermis and facilitating the subsequent dental implant operation.

[0008] The other end of the knife handle is connected to one end of the second transition connecting rod, and the other end of the second transition connecting rod is connected to the second knife head, which is a hook-shaped structure. After the outer gingival epidermis is vertically grooved, the hook-shaped second knife head can be flexibly operated due to the limited operating space.

[0009] Among them, the outer sides of the second cutting head are all provided with cutting edges, and the second cutting head can cut in three directions.

[0010] Among them, as another preferred cutter head structure, the first cutter head has a cutting edge on one side.

[0011] Among them, as another preferred cutter head structure, the first cutter has cutting edges on both sides.

[0012] Along the length of the handle, there are multiple anti-slip strips arranged at equal angles around the central axis of the handle. When the doctor is operating, the friction between the fingers and the handle is increased, and the hands will not slip, thus preventing the handle from falling off between the fingers and affecting the surgical operation.

[0013] The cross section of the handle is a regular hexagon or a circle.

[0014] Compared with the prior art, the utility model has the following specific beneficial effects: the utility model arranges the first cutter head transversely on one side of the knife handle, and the first cutter head is arranged vertically with the guide connecting rod. After the inner gingival surface is vertically grooved, the transversely arranged first cutter head can quickly make transverse grooves in the horizontal direction. During the operation of the first cutter head, the transversely arranged first cutter head will not cause vertical cutting to the gingival epidermis, thus avoiding damage to the gingival epidermis, and providing convenience for subsequent dental implants. In addition, the utility model arranges a second hook-shaped cutter head on the other side of the knife handle. When vertically grooving the outer gingiva, the second cutter head can be operated in a small space to avoid damage to the gingival epidermis. The entire device of the utility model has a reasonable structure, good reliability, and convenient operation, and can be widely promoted and applied in the field of dental medicine.

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Example

[0024] like Figure 1-2 As shown, a gum transplant cutting device includes a handle 1, which is a straight rod structure, one end of the handle 1 is connected to one end of a first transition link 2, and the other end of the first transition link 2 is connected to a first cutter head 4 through a guide link 3. The first transition link 2 is smoothly connected to the guide link 3, the central axis of the handle 1 overlaps with the central axis of the first transition link 2, the central axis of the first transition link 2 and the central axis of the guide link 3 are arranged at an angle of 30°-60°, the first cutter head 4 is vertically arranged on the side of the guide link 3, and the tip of the first cutter head 4 extends outward.

[0025] The other end of the handle 1 is connected to one end of the second transition link 5, and the other end of the second transition link 5 is connected to the second cutter head 6, which is a hook-shaped structure. After the outer gum 7 is vertically grooved, the hook-shaped second cutter head 6 can be flexibly operated due to the limited operating space.

[0026] Among them, the outer sides of the second blade head 6 are all provided with blades, and the second blade head 6 can cut in three directions.

[0027] The first blade head 4 is a sword-blade structure, and blades are formed on both sides of the first blade head 4 .

[0028] Along the length direction of the knife handle 1, a plurality of anti-slip strips are arranged on the knife handle 1, and the plurality of anti-slip strips are arranged at equal angles around the central axis of the knife handle 1. When the doctor is operating, the friction between the fingers and the knife handle 1 is increased, and the hands will not slip, thereby preventing the knife handle 1 from falling off between the fingers and affecting the surgical operation.

[0029] The cross section of the knife handle 1 is a regular hexagon or a circle.

[0030] like Figure 5 As shown, when it is necessary to groove the inner gum 7, the oral cavity is opened, and when the doctor holds the knife handle 1 to operate, the first blade head 4 enters the oral cavity obliquely downward. After the epidermis of the inner gum 7 is grooved vertically, the transversely arranged first blade head 4 can facilitate transverse grooves. The first blade head 4 can be pulled and pushed transversely to cut the epidermis of equal thickness without cutting the epidermis at the top of the transverse groove 8, thereby avoiding damage to the epidermis of the gum 7 and facilitating the subsequent dental implant operation.

[0031] When it is necessary to groove the outer gum 7, the oral cavity is opened, and the doctor holds the knife handle 1 to operate, and pushes and pulls the second knife head 6 horizontally to cut the epidermis of equal thickness on the outer gum 7, avoiding damage to the epidermis of the outer gum 7 and facilitating the subsequent dental implant operation. Example

[0032] like Figure 3 As shown, the difference between this embodiment and the first embodiment lies in the shape of the blade head 4. The blade head 4 of this embodiment is an axe-shaped blade with a single-side edge. Example

[0033] like Figure 4 As shown, the difference between this embodiment and the first embodiment lies in the shape of the cutter head 4. The cutter head 4 of this embodiment is a wide head type and a double-sided blade structure, which makes horizontal grooving faster.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the scope of the present invention.
