[0002] Dental suture forceps is a tool specially used for suturing in oral surgery. It is usually made of stainless steel or other corrosion-resistant materials, with a specific shape and design to meet the needs of dental surgery. Dental suture forceps is one of the tools commonly used by dentists in various oral surgeries, which can help doctors perform delicate and accurate suturing operations, promote wound healing and restore oral health.

[0003] The existing dental suture forceps have a small bending angle at the front end. When medical staff are suturing inside the patient's mouth, they need to raise their arms very high during the clamping process to facilitate clamping. At the same time, the outer side of the suture forceps is flat, which reduces the contact area with the medical staff's fingers, reducing comfort and worsening the anti-slip effect. Therefore, the present application provides a pair of tweezers to meet the needs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a tweezers to solve the problem that the bending angle of the front end of the existing dental suture tweezers is small, and the medical staff needs to raise their arms very high in the process of clamping the tissue when suturing inside the patient's mouth, so as to facilitate clamping, and at the same time, the outer side of the suture tweezers is flat, and the contact area with the fingers of the medical staff is reduced, which reduces the comfort and also worsens the anti-slip effect.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A pair of tweezers includes a tweezer body, wherein the tweezer body includes a first clamping handle and a second clamping handle fixedly connected at one end, the first clamping handle and the second clamping handle have the same structure and specification, one end of the first clamping handle and the second clamping handle are respectively fixedly connected with a chuck structure, and the outer surfaces of the first clamping handle and the second clamping handle and the user's holding position are provided with an anti-slip structure.

[0008] Optionally, the clamp structure includes a clamp ring fixed to one end of the operating section, the clamp ring is provided with a U-shaped bayonet, and the opposite side surfaces of the two clamp rings are provided with corrugated grooves.

[0009] Optionally, the orientation of the U-shaped bayonet is perpendicular to the extension direction of the gripping section, and the inner spacing of the U-shaped bayonet is 2 mm.

[0010] Optionally, the anti-slip structure includes an anti-slip groove opened on the outer wall of the grip section.

[0011] Optionally, the anti-slip groove is formed by splicing a plurality of groups of evenly arranged rhombus grooves, and three interconnected rhombus grooves opened along the arc direction of the outer wall of the grip section form a group.

[0012] Optionally, outer side surfaces of the operating section, the steering section, the gradient section and the holding section are all semicircular arc structures corresponding to their widths, and both side surfaces of the holding section are parallel to each other.

[0013] Optionally, a through limiting groove is provided on the gradient section, a limiting column is fixedly connected to the inner surface of the second clamping handle at a position corresponding to the limiting groove, and the first clamping handle and the second clamping handle are adaptively connected to each other via the limiting groove and the limiting column.

[0014] Optionally, the tweezers body is integrally formed by die-casting.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above scheme, by setting an anti-slip structure, the diamond grooves on the anti-slip grooves can increase the contact area with the fingers and palms of medical staff, improve friction, and effectively increase the anti-slip effect. The diamond grooves can enable the fingers to better grip the surface, reduce the possibility of sliding, and improve the stability and safety of the operation.

[0017] By setting the clamp structure, the direction of the U-shaped bayonet is perpendicular to the extension direction of the gripping section. The vertical setting can reduce the height of the medical staff's arm when clamping the tissue to be sutured in the oral cavity. During long suturing operations, the physical energy consumed by the medical staff will be reduced, and the lowered arm will increase the comfort of the medical staff. The U-shaped bayonet can make it easier for the clamp structure to enter and exit the suture line.

[0032] like Figure 1 and Figure 2As shown, an embodiment of the utility model provides a pair of tweezers, including a tweezers body 1, which is integrally formed by die-casting. The molten metal is injected into a mold under high pressure to solidify inside the mold. The tweezers body 1 has high production efficiency, short production cycle, relatively low cost and stable product quality. The tweezers body 1 includes a first clamping handle 11 and a second clamping handle 12 fixedly connected at one end. The first clamping handle 11 and the second clamping handle 12 have the same structure and specification. One end of the first clamping handle 11 and the second clamping handle 12 are respectively fixedly connected with a chuck structure 4, and the chuck structure 4 is used to clamp the tissue to be sutured inside the oral cavity. The outer surfaces of the first clamping handle 11 and the second clamping handle 12 and the user's hand-holding position are provided with an anti-slip structure. The anti-slip structure can increase the friction between the tweezers body 1 and the user's fingers when the medical staff holds them, so as to avoid the situation where the medical staff's gloves are stuck with blood and tissue fluid during the operation, causing them to slip when holding the tweezers body 1.

[0033] like Figure 2As shown, the first clamping handle 11 is formed by sequentially connecting an operating section 112, a turning section 113, a gradual section 114, a gripping section 115 and a fixed section 116. The fixed section 116 is used to fix the first clamping handle 11 and the second clamping handle 12. The gripping section 115 provides a holding position for the user. The width of the gradual section 114 gradually changes from the gripping section 115 to the turning section 113. The width of the gradual section 114 and the turning section 113 gradually changes from wide to low from the gripping section 115 to the operating section 112 until they are consistent with the width of the operating section 112. Through its gradual width, the first clamp handle 11 and the second clamp handle 12 can be more convenient for medical staff to operate inside the patient's mouth. The turning section 113 is used to provide a bending angle for the operating section 112. The operating section 112 is fixedly connected to the clamp structure 4. The outer surfaces of the operating section 112, the turning section 113, the gradual section 114 and the gripping section 115 are all semi-circular structures corresponding to their widths. The semi-circular structures on the surfaces of the operating section 112, the turning section 113, the gradual section 114 and the gripping section 115 can increase the gripping effect. The contact area between the section 115 and the fingers and palms of the medical staff can make the outer surfaces of the operating section 112, the turning section 113 and the gradient section 114 smooth and round. When the suturing operation is performed in the patient's mouth, no pressure and friction will be formed on the tissue outside the patient's oral wound, avoiding the situation where other oral tissues are squeezed and injured during the surgical suturing process. The two side surfaces of the gripping section 115 are parallel to each other, and a through limiting groove 111 is provided on the gradient section 114. The inner surface of the second clamping handle 12 is at a position corresponding to the limiting groove 111. The limiting column 121 is fixedly connected, and the first clamping handle 11 and the second clamping handle 12 are adapted to be connected to the limiting column 121 via the limiting groove 111. The limiting column 121 and the limiting groove 111 cooperate with each other to ensure the relative clamping force of the first clamping handle 11 and the second clamping handle 12 when the tweezers body 1 is clamping. At the same time, it also ensures that when the tweezers body 1 clamps the oral tissue and sutures, the operating section 112, the turning section 113, the gradient section 114 and the clamping head structure 4 will not be misaligned due to excessive force, thereby increasing the service life of the tweezers body 1.

[0034] like Figure 2 and Figure 3As shown, the clamp structure 4 includes a clamp ring 41 fixed to one end of the operating section 112, and a U-shaped bayonet 42 is provided on the clamp ring 41, and corrugated grooves 3 are provided on the opposite side surfaces of the two clamp rings 41. The direction of the U-shaped bayonet 42 is perpendicular to the extension direction of the holding section 115. The vertical setting can reduce the height of the medical staff's arm when clamping the tissue to be sutured in the oral cavity. During a long suturing operation, the physical energy consumed by the medical staff will be reduced, and the lowering of the arm will increase the comfort of the medical staff. The inner spacing of the U-shaped bayonet 42 is 2mm. The 2mm U-shaped bayonet 42 design can make it easier for the clamp structure 4 to enter and exit the suture line. At the same time, when performing bone block or bone chip transplantation, the bone block or bone chip to be transplanted is clamped and guided for drilling through the clamp structure 4, and during the clamping process, the fixing screw directly passes through the U-shaped bayonet 42 for fixing, and when the screw is screwed into the preset hole, the tweezers body 1 can be pulled out through the U-shaped bayonet 42.

[0035] like Figure 2 and Figure 4 As shown, the anti-skid structure includes an anti-skid groove 2 opened on the outer wall of the gripping section 115, and the anti-skid groove 2 is formed by splicing a plurality of groups of evenly arranged diamond grooves. Three interconnected diamond grooves opened along the arc direction of the outer wall of the gripping section 115 form a group. The diamond groove can increase the contact area with the fingers and palms of medical staff, improve friction, and effectively increase the anti-skid effect. The diamond groove can enable the fingers to better grip the surface, reduce the possibility of sliding, and improve the stability and safety of operation.

[0036] The working principle provided by the utility model is that when the medical staff needs to clamp and suture the tissue in the oral cavity, the medical staff holds the holding section 115 on the first clamp handle 11 and the second clamp handle 12. The holding section 115 with a semicircular structure can increase the contact area between the holding section 115 and the fingers and palm of the medical staff. At the same time, the anti-skid groove 2 on the outer wall of the holding section 115 can increase the contact area with the fingers and palm of the medical staff, improve the friction, and effectively increase the anti-skid effect. The diamond groove can enable the fingers to better grasp the surface, reduce the possibility of sliding, and improve the stability and safety of the operation. Then, by operating the first clamp handle 11 and the second clamp handle 12, the two clamp rings 41 clamp the tissue to be sutured of the patient, and then suture is performed. After the suturing is completed, under the recovery deformation force between the first clamp handle 11 and the second clamp handle 12, the first clamp handle 11 and the second clamp handle 12 return to the initial state, and then suture is performed at the next position.

[0037] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
