Description

Dental tweezers

[0001] The present invention relates to a dental tweezers, and more specifically, to a dental tweezers comprising a clamp portion (11) composed of a combination of a pair of clamps, a gripping portion (21) set on each outer surface of the clamps and adjusting the distance formed by the clamps, and further comprising a twist prevention portion (14, 15) arranged offset from each other on the pair of clamps and guiding the respective clamps to prevent twisting and to allow alignment when the pair of clamps approach each other closely.

[0002] Tweezers and forceps are commonly used in a wide range of fields, including medicine, home economics, chemistry, and mechanical engineering, to grasp various objects; they have been modified to suit specific purposes by adopting different shapes and materials.

[0003] In general, medical tweezers are widely and conveniently used to treat wounds without direct contact with the hands, for the purpose of preventing contamination of the wound site during medical procedures.

[0004] It is common for such medical tweezers to have a handle on the upper side, a gripping portion on the lower side of the handle, and a clamp integrally formed on the lower side of the gripping portion.

[0005] Meanwhile, unlike general tweezers, those used for specialized medical care or OB / GYN examinations are relatively long, requiring the maintenance of gripping force through a significant level of pressure. However, maintaining gripping force at the tips of such extended tweezers is difficult, which not only adds another burden to medical staff but also acts as a significant stress factor during medical procedures as twisting frequently occurs during the gripping process.

[0006] For example, when medical procedures such as dressing are performed by inserting forceps into the speculum to treat female diseases, the forceps must reach deep inside the vagina, so they are inevitably quite long. As mentioned above, this not only causes difficulty in exercising gripping force but also causes fatal problems, such as the forceps easily twisting due to the length extension, which is a characteristic of the narrow width of the forceps.

[0007] The prior art patent documents regarding tweezers developed and implemented to date are as follows.

[0008] Patent Application No. 10-2005-0080507 (20050829) relates to a tweezers with enhanced friction force, wherein a plurality of gripping protrusions with pointed ends are formed protruding at staggered positions on the inner side of the gripping end of the tweezers, and the gripping protrusions are formed with industrial diamonds, thereby minimizing the contact area between the tweezers and the prosthesis when coating with enamel or ceramic while the tweezers are gripping the prosthesis, and furthermore, the gripping force (friction) with the prosthesis is strengthened by the gripping protrusions, allowing the object to be gripped more easily.

[0009] In addition, Patent Application No. 10-2011-0127881 (20111201) relates to a suturing forceps used in guided bone regeneration, characterized in that a pair of body parts, each having a clamp portion on one side and a handle portion on the other side, are joined such that one end is spaced apart and the other end is joined, and the clamp portion is formed to be openable and closable by the handle portion, and a guide groove is formed on one or both sides of the pressure surface facing the clamp portion to support a shielding membrane with the pressure surface while allowing a suture needle to easily penetrate the gum tissue along the guide groove.

[0010] However, the aforementioned prior art not only lacks technical concepts directly involved in improving twisting or gripping force when using tweezers in medical procedures, but also fails to satisfy the setting conditions required, particularly in obstetrics and gynecology, thus raising the need for improvement.

[0011] In particular, dental mirrors, explorers, and pincettes are instruments necessary for all dental procedures and can be called "basic instruments." Dental procedures are performed by both the practitioner and an assistant, but there is a functional limitation in that the three basic instruments mentioned above cannot perform retraction simultaneously by two people.

[0015] (Patent Document 0002) Patent Application No. 10-2011-0127881

[0016] The present invention aims to enable two or more people to perform the traction function, which is always required by the practitioner or assistant during dental treatment, more conveniently and simultaneously by adding a shape capable of performing a traction function to the opposite side of the clamp of dental tweezers.

[0017] In particular, it aims to change the center of gravity of the tweezers to allow the user to feel greater control when manipulating the clamps and to reduce wrist fatigue.

[0018] In addition, an "anti-rotation jig" is added to prevent the clamp from twisting to both sides around the object as an axis. Conventionally, when gripping force is applied with the thumb and index finger, there is an up-and-down twisting force, which caused the tip of the clamp to twist with the object in between.

[0019] In addition, once purchased, tweezers are used for a relatively long time, and there is a problem that the tweezers material is prone to deterioration as they undergo a high-temperature and high-pressure sterilization process every time.

[0020] The present invention aims to ensure that force is properly transmitted to the tip of the gripper through a twist-prevention jig to prevent twisting caused by the two reasons mentioned above, thereby enabling the precise gripping of small objects.

[0021] The present invention provides the following means for solving the problem to solve the above problem.

[0022] A clamp part (11) composed of a combination of a pair of clamps,

[0023] It includes a gripping part (21) that is set on each outer surface of the above clamp and adjusts the distance formed by the above clamp,

[0024] The apparatus further includes a twist prevention member (14, 15) that is positioned offset from each other on the pair of clamps and guides the respective clamps to prevent twisting and to align when the pair of clamps approach each other closely.

[0025] Provides dental tweezers.

[0026] It further includes a traction portion (32) that extends from the end of the gripping portion (21), and

[0027] The end portion of the above-mentioned traction portion (32) is characterized by having a shape that extends upward or downward from the above-mentioned gripping portion (21).

[0028] The above gripper part (11) includes an extension part (12) formed extending from the gripping part (21), an end part (11) for gripping an object, and a bending part (13) connecting the extension part (12) and the end part (11).

[0029] The above anti-twisting parts (14, 15) are characterized by being provided on the extension part (12).

[0030] The present invention has the advantage of allowing two people to perform traction simultaneously with three basic instruments, by adding a shape capable of performing a traction function to the opposite side of the clamp of dental tweezers, thereby making the traction function that is always needed by the practitioner or assistant during dental treatment more convenient.

[0031] In particular, by changing the center of gravity of the tweezers, it allows the user to feel greater control when manipulating the clamp and has the effect of reducing wrist fatigue.

[0032] In this invention, the force is properly transmitted to the tip of the gripper through a twist-prevention jig to prevent twisting caused by the two reasons mentioned above, and it has the effect of enabling precise gripping of small objects.

[0046] Hereinafter, embodiments of the present invention will be described in more detail with reference to the attached drawings. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms; these embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention. Identical reference numerals in the drawings refer to identical elements.

[0047] It should be noted that when assigning reference numerals to the components of each drawing, the same components are assigned the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the present invention, if it is determined that a detailed description of related known components or functions could obscure the essence of the invention, such detailed description is omitted.

[0048] The present invention will be described in more detail below with reference to the drawings.

[0049] The present invention provides the following means for solving the problem to solve the above problem.

[0050] A dental tweezers is provided, comprising a clamp portion (11) composed of a combination of a pair of clamps, a gripping portion (21) set on each outer surface of the clamps and adjusting the distance formed by the clamps, and further comprising a twist prevention portion (14, 15) arranged offset from each other on the pair of clamps and guiding the respective clamps to prevent twisting and to allow alignment when the pair of clamps approach each other closely.

[0051] It further includes a traction portion (32) that extends from the end of the gripping portion (21), and the end portion of the traction portion (32) is characterized by having a shape that extends upward or downward from the gripping portion (21).

[0052] The above clamping part (11) includes an extension part (12) formed extending from the above gripping part (21), an end part (11) for gripping an object, and a bending part (13) connecting the extension part (12) and the end part (11), and the above twisting prevention part (14, 15) is provided on the extension part (12).

[0053] The present invention will be described in detail below with reference to the attached drawings.

[0054] FIG. 1 shows a perspective view of a conventional dental tweezers, FIG. 2 shows an embodiment of a dental tweezers according to the present invention, FIG. 3 shows an embodiment of a dental tweezers according to the present invention, FIG. 4 shows an embodiment of a dental tweezers according to the present invention, FIG. 5 shows an embodiment of a dental tweezers according to the present invention, FIG. 6 shows an embodiment of a dental tweezers according to the present invention, FIG. 7 shows an embodiment of a dental tweezers according to the present invention, and FIG. 8 shows an embodiment of a dental tweezers according to the present invention.

[0055] The present invention has the advantage of allowing two people to perform traction simultaneously with three basic instruments, by adding a shape capable of performing a traction function to the opposite side of the clamp of dental tweezers, thereby making the traction function that is always needed by the practitioner or assistant during dental treatment more convenient.

[0056] In particular, it aims to change the center of gravity of the tweezers to allow the user to feel greater control when manipulating the clamps and to reduce wrist fatigue.

[0057] In addition, an "anti-rotation jig" is added to prevent the clamp from twisting to both sides around the object as an axis. Conventionally, when gripping force is applied with the thumb and index finger, there is an up-and-down twisting force, which caused the tip of the clamp to twist with the object in between.

[0058] In addition, once purchased, tweezers are used for a relatively long time, and there is a problem that the tweezers material is prone to deterioration as they undergo a high-temperature and high-pressure sterilization process every time.

[0059] The present invention aims to ensure that force is properly transmitted to the tip of the gripper through a twist-prevention jig to prevent twisting caused by the two reasons mentioned above, thereby enabling the precise gripping of small objects.

[0060] FIGS. 2 and 3 specifically describe the anti-twisting parts (14, 15), which are the main technical features of the present invention. The anti-twisting parts are composed of a pair. As shown in FIG. 3, they are shaped like a U and are configured to be fitted in a direction opposite to the extension part (12) of the clamp part.

[0061] One side of the anti-twist part (15) has an upper portion (18) that protrudes long, and the other side of the anti-twist part (14) has a lower portion (16) that protrudes long.

[0062] The long protruding part performs the function of preventing misalignment so that when the clamp parts approach each other and narrow the distance, the other clamp part does not become twisted due to torsion and maintains a straight alignment.

[0063] Another major feature of the present invention is the traction portion (32). The traction portion (32) is formed by extending from the point where a pair of gripping portions meet each other. The end portion of the traction portion (32) is positioned and shaped to change the center of gravity of the tweezers so that the operator can use the tweezers with one hand and perform the traction function with only one hand. That is, various shapes are provided to shift the center of gravity upward or downward relative to the extension line of the gripping portion.

[0064] As shown in Fig. 4, if the shape of the end of the traction part is circular, the center of gravity is placed at the back of the tweezers so that the tweezers can be tractioned to the back without the help of the other hand or another person during the procedure performed by the operator with one hand.

[0065] As shown in Fig. 5, when the shape of the end of the traction part is made elliptical, the center of gravity is placed at the rear of the tweezers, but the vertical width is not large compared to the width of the gripping part, so the traction function can be adjusted to be slightly weaker.

[0066] As shown in Fig. 6, if the shape of the end of the traction part is an elliptical shape with a wide vertical direction, the center of gravity is sent less to the rear, and the traction function can be adjusted to be slightly stronger.

[0067] As shown in Fig. 7 or Fig. 8, if the shape of the end of the traction part is lowered or raised relative to the width of the gripping part, the traction function and direction can be adjusted in various ways to suit the intended use of the tweezers.

[0068] The foregoing description is merely an illustrative explanation of the technical concept of the present invention, and those skilled in the art to which the present invention pertains will be able to make various modifications and variations within the scope of the essential characteristics of the present invention. Accordingly, the embodiments disclosed in the present invention are intended to explain, not limit, the technical concept of the present invention, and the scope of the technical concept of the present invention is not limited by these embodiments. The scope of protection of the present invention shall be interpreted by the claims below, and all technical concepts within an equivalent scope shall be interpreted as being included within the scope of rights of the present invention.
