Abstract
Description
[0001] Clamping utensil
[0002] FIELD OF INVENTION
[0003] The present invention relates to clamping utensils.
[0004] BACKGROUND OF THE INVENTION
[0005] Clamping utensils are useful in a variety of applications for grasping or clamping different objects. However, there is a need for a clamping utensil that requires low application force when used while being simple and cheap to produce.
[0006] Hence, there is a need for an improved clamping utensil.
[0007] SUMMARY OF THE INVENTION
[0008] It is thus in view of the above a need for an improved clamping utensil that is adaptable in dealing with the aforementioned problems.
[0009] According to a first aspect of the present invention, a clamping utensil is provided, the clamping utensil comprising: a body having a longitudinal axis and comprising a first member and a second member extending along the longitudinal axis, wherein at least the first member is flexible, the first and second member being connected at a first point and a second point, the first point being arranged between a distal end of the body and the second point as seen along the longitudinal axis, wherein a respective mid portion of each member extending between the first point and the second point forms a handle portion; and a first set of prongs comprising at least one prong and a second set of prongs comprising at least one prong, the first set of prongs being provided on a respective end portion of the first member and the second set of prongs being provided on a respective end portion of the second member, each set of prongs being provided at the distal end of the body; wherein the clamping utensil is configured such that compression of the handle portion forces the mid portion of the first member towards the mid portion of the second member so as to displace the first set of prongs around the first point and from the second set of prongs.
[0010] Since compression of the handle portion displaces at least the first set of prongs in relation to the second set of prongs, the first point act as a fulcrum facilitating pivoting motion of the first set of prongs whereby a larger distance between the first set of prongs and the second set of prongs is achieved. Thus, a larger space in which items may be received is formed. Further, less force is required by the user in order to e.g. grip or move different items.
[0011] Correspondingly, the first set of prongs may return to its initial state when the handle portion is released, since the member is flexible. Thereby different items may be grasped or clamped by the clamping utensil by releasing the handle portion. Thus, less constantly applied force is required by the user in order to e.g. grip or move different items compared with a conventional clamping utensil.
[0012] The second member may also be flexible. Thus, compression of the handle portion forces the respective mid portions of the first member and the second member towards each other so as to displace the first set of prongs and the second set of prongs around the first point and away from each other. Hence, the distance between the first set of prongs and the second set of prongs, created by the pivoting motion around the first point, will be further increased.
[0013] The first and second members of the clamping utensil may be arranged in parallel. That they are arranged in parallel is to be understood as each member having a respective extension, or component of extension, which extensions or components of extension are parallel with each other.
[0014] The clamping utensil may be made of, or comprise, any suitable material. It is to be understood that depending on choice of material or materials, any flexible member is to be dimensioned in a suitable manner.
[0015] The clamping utensil may e.g. be made in an extrusion process, by 3d- printing, casting, injection moulding, or by flat cutting and folding of a material.
[0016] The clamping utensil may have any suitable length, or material thickness. Further, the first and second members may be of equal, or different, lengths. Furthermore, the first and second members may have equal, or different, material thickness. For example, the first member may have a smaller material thickness, i.e. be thinner, than the second member, such that the first member is flexible, or at least more flexible than the second member.
[0017] The first point of the clamping utensil is distanced from the second point as seen along the longitudinal axis. The mid portion of each member may fully or partially extend between the first and second point. Hence, the handle portion may also fully or partially extend between the first and second point. It is to be understood that the extension of the mid portion and / or the distance between the first point and the second point is to be chosen in relation to the material and material thickness of the members such that compression of the handle portion is feasible.
[0018] The first and second member may be connected to each other in a variety of ways. For example, the first and second member may be fixedly connected at the first and / or the second point. Hereby, the structural integrity of the clamping utensil is improved. The first and the second member may e.g. be integrally formed such that they are fixedly connected at the first and / or the second point. For example, the first member and the second member may be connected by a living hinge at the first point and / or the second point.
[0019] Within the context of the present disclosure, a “living hinge" is to be understood as a flexible hinge made from the same material as and being integrally formed with the members it connects. Thus the clamping utensil may be continuously formed by the same material with a thin, flexible segment connecting the two members. Additionally or alternatively, the first and second member may be fixedly connected to each other by, e.g., means of adhesion or a locking pin.
[0020] Alternatively, at the first point and / or the second point, the first member may comprise one of a receiving portion and an engagement portion, and the second member may comprise a complementary receiving portion or engagement portion, wherein the engagement portion is releasably connected to the receiving portion. Hereby, the first member and the second member may be selectively connected and disconnected at the first point and / or the second point. The first and second member may be fixedly connected at the first point, and releasably connected at the second point or vice versa. Alternatively, both the first point and the second point may be releasably connected, or conversely, fixedly connected. If both the first point and the second point are releasably connected, the first member and the second member may be selectively connected and disconnected. Hereby, the members may be stored and / or transported in a disconnected, more space-efficient, manner. It is also possible to replace parts when needed, instead of discarding the whole clamping utensil.
[0021] The receiving portion may comprise a groove and the engagement portion may comprise a protrusion. Alternatively, the receiving portion may comprise a cutout arranged in a side edge of the respective member, and the engagement portion may comprise a projecting portion arranged on a side edge of the respective member and extending transverse to the longitudinal axis of the body, and wherein the cut-out is provided with a pin-hole and the projecting portion is provided with a pin, the pin extending transverse to the projecting portion and being rotatably arranged in the pin-hole. Furthermore, any member may comprise a cut-out on two opposite side edges. The pin-hole may thus be a through hole, extending from the cut-out in one side edge, to the cut-out of the opposite side edge. Similarly, any member may comprise a first and a second projecting portion arranged on two opposite side edges such that the pin may extend between the projecting portions. Moreover, the pin extending between the projecting portions may be arranged in the through hole.
[0022] The projecting portion may have a semi-circular shape, wherein the cut-out has a shape complementary to the projecting portion.
[0023] The prongs of the first set and the second set of prongs may have a variety of shapes. For example, the at least one prong in the first set of prongs may be formed as a hollow body comprising an inner and an outer flexible segment, wherein the hollow body is configured such that pressing of the outer flexible segment towards the inner flexible segment displaces the inner flexible segment in a bending motion from the second set of prongs.
[0024] The bending motion of the inner flexible segment will cause an actuation of the clamping utensil, the actuation being smaller than the displacement of the prongs caused by compression of the handle portion. Thereby the clamping utensil may be actuated in a precise movement, and is thus suitable for grasping of items that requires more precision.
[0025] Alternatively, the prongs may be tine-shaped. For at least one of the first set and the second set of prongs, the prong neighboring the other set of prongs may be provided with teeth on a side surface thereof, the side surface facing the other set of prongs. In other words, in the first set of prongs, the prong being adjacent to the second set of prongs may be provided with teeth. Additionally or alternatively, the corresponding prong in the second set of prongs, being adjacent to the first set of prongs may also be provided with teeth. Thus, when the handle portion is released in order to grip an item, the teeth will provide increased friction and a larger contact surface which improves the ability of gripping the item.
[0026] For example, teeth may be provided on the inner flexible segment of a prong formed as a hollow body in the first set of prongs. Respectively, the inner flexible segment of a prong in the second set of prongs may also be provided with teeth. The teeth may be provided on the respective inner flexible segments such that the teeth face the adjacent set of prongs.
[0027] Additionally or alternatively, the inner flexible segment of a prong in the first set of prongs may have a friction increasing shape. For example, the inner flexible segment may have a zig-zag or a wave-like shape. This shape of the inner flexible segment may facilitate gripping of items. The inner flexible segment of the neighbouring prong in the second set of prongs may comprise a complementary zigzag or wave-like shape such that the prong in the first set of prongs may nest the prong in the second set of prongs.
[0028] A respective second end portion of each member may extend from the second point to a second distal end of the body, the second distal end being opposite to the distal end as seen along the longitudinal axis, the respective second end portion may form a clamping portion and wherein the clamping utensil may be further configured such that compression of the handle portion forces the mid portion of the first member towards the mid portion of the second member so as to actuate the clamping portion. Actuating the clamping portion is to be understood as displacing the second end portion of the first member around the second point and from the second end portion of the second member. The clamping portion may be provided with teeth. The teeth provide increased friction and a larger contact surface which improves the ability of gripping items.
[0029] However, it should be understood that the clamping portion may be provided as a pair of prongs. That is, the respective second end portion of each member, extending to the second distal end of the body may be a prong.
[0030] The clamping utensil may be an eating utensil. That is, the clamping utensil may be configured for gripping food items. The eating utensil may comprise: a body having a longitudinal axis and comprising a first member and a second member extending along the longitudinal axis, wherein at least the first member is flexible, the first and second member being connected at a first point and a second point, the first point being arranged between a distal end of the body and the second point as seen along the longitudinal axis, wherein a respective mid portion of each member extending between the first point and the second point forms a handle portion; and a first set of prongs comprising at least one prong and a second set of prongs comprising at least one prong, the first set of prongs being provided on a respective end portion of the first member and the second set of prongs being provided on a respective end portion of the second member, each set of prongs being provided at the distal end of the body; wherein the eating utensil is configured such that compression of the handle portion forces the mid portion of the first member towards the mid portion of the second member so as to displace the first set of prongs around the first point and from the second set of prongs.
[0031] Since compression of the handle portion displaces at least the first set of prongs in relation to the second set of prongs, the first point act as a fulcrum facilitating pivoting motion of the first set of prongs whereby a larger distance between the first set of prongs and the second set of prongs is achieved. Thus, a larger space in which a piece of food may be received is formed. Hence, food items that are difficult to pierce or scoop can instead be gripped by release of the handle portion, making it easier to pick up such food items with a single utensil. Hereby, a multi-functional eating utensil is provided.
[0032] The second member may also be flexible. Thus, compression of the handle portion forces the respective mid portions of the first member and the second member towards each other so as to displace the first set of prongs and the second set of prongs around the first point and away from each other. Hence, the distance between the first set of prongs and the second set of prongs, created by the pivoting motion around the first point, will be further increased. Therefore larger pieces of food may be received and gripped by the eating utensil.
[0033] The first and second members of the eating utensil may be arranged in parallel. That they are arranged in parallel is to be understood as each member having a respective extension, or component of extension, which extensions or components of extension are parallel with each other.
[0034] The eating utensil may be made of, or comprise, any suitable material, such as metal, wood or polymeric material, such as acrylic, PET, polypropylene, polycarbonate, polyethylene, polystyrene, epoxy, and / or a biodegradable polymeric material. It is to be understood that depending on choice of material or materials, any flexible member is to be dimensioned in a suitable manner.
[0035] The eating utensil may e.g. be made in an extrusion process, or by 3d- printing, casting, injection moulding, or by flat cutting and folding of a material.
[0036] The eating utensil may have any suitable length, or material thickness. Further, the first and second members may be of equal, or different, lengths. Furthermore, the first and second members may have equal, or different, material thickness. For example, the first member may have a smaller material thickness, i.e. be thinner, than the second member, such that the first member is flexible, or at least more flexible than the second member.
[0037] The eating utensil may be configured such that the body further comprises a scoop portion extending between the first point and the prongs. Hereby, the utensil is provided with a curvature as seen transverse to the longitudinal axis of the body so as to facilitate ladling of food items.
[0038] The first point is distanced from the second point as seen along the longitudinal axis. The mid portion of each member may fully or partially extend between the first and second point. Hence, the handle portion may also fully or partially extend between the first and second point. It is to be understood that the extension of the mid portion and / or the distance between the first point and the second point is to be chosen in relation to the material and material thickness of the members such that compression of the handle portion is feasible.
[0039] The first and second member may be connected to each other in a variety of ways. For example, the first and second member may be fixedly connected at the first and / or the second point. Hereby, the structural integrity of the eating utensil is improved. The first and the second member may e.g. be integrally formed such that they are fixedly connected at the first and / or the second point. For example, the first member and the second member may be connected by a living hinge at the first point and / or the second point.
[0040] Additionally or alternatively, the first and second member may be fixedly connected to each other by, e.g., means of adhesion or a locking pin.
[0041] Alternatively, at the first point and / or the second point, the first member may comprise one of a receiving portion and an engagement portion, and the second member may comprise a complementary receiving portion or engagement portion, wherein the engagement portion is releasably connected to the receiving portion. Hereby, the first member and the second member may be selectively connected and disconnected at the first point and / or the second point. The first and second member may be fixedly connected at the first point, and releasably connected at the second point or vice versa. Alternatively, both the first point and the second point may be releasably connected, or conversely, fixedly connected. If both the first point and the second point are releasably connected, the first member and the second member may be selectively connected and disconnected. Hereby, the members may be stored and / or transported in a disconnected, more space-efficient, manner. It is also possible to replace parts when needed, instead of discarding the whole eating utensil.
[0042] The receiving portion may comprise a groove and the engagement portion may comprise a protrusion. Alternatively, the receiving portion may comprise a cutout arranged in a side edge of the respective member, and the engagement portion may comprise a projecting portion arranged on a side edge of the respective member and extending transverse to the longitudinal axis of the body, and wherein the cut-out is provided with a pin-hole and the projecting portion is provided with a pin, the pin extending transverse to the projecting portion and being rotatably arranged in the pin-hole. Furthermore, any member may comprise a cut-out on two opposite side edges. The pin-hole may thus be a through hole, extending from the cut-out in one side edge, to the cut-out of the opposite side edge. Similarly, any member may comprise a first and a second projecting portion arranged on two opposite side edges such that the pin may extend between the projecting portions. Moreover, the pin extending between the projecting portions may be arranged in the through hole.
[0043] The projecting portion may have a semi-circular shape, wherein the cut-out has a shape complementary to the projecting portion.
[0044] The prongs of the first set and the second set of prongs may have a variety of shapes. For example, the at least one prong in the first set of prongs may be formed as a hollow body comprising an inner and an outer flexible segment, wherein the hollow body is configured such that pressing of the outer flexible segment towards the inner flexible segment displaces the inner flexible segment in a bending motion from the second set of prongs.
[0045] The bending motion of the inner flexible segment will cause an actuation of the clamping utensil, the actuation being smaller than the displacement of the prongs caused by compression of the handle portion. Thereby the clamping utensil may be actuated in a precise movement, and is thus suitable for grasping of food items that requires more precision.
[0046] As another example, the prong in the first set of prongs, neighboring the second set of prongs, and the prong in the second set of prongs neighboring the first set of prongs may be arranged against each other, wherein the prongs are shaped so as to form a spoon-shaped structure. Alternatively the prongs may be tineshaped. Further, the first set of prongs and the second set of prongs may comprise different numbers of prongs. Each set of prongs may, e.g., comprise at least two prongs. Alternatively, the first set of prongs may comprise at least one prong, while the second set of prongs may comprise at least two prongs and vice versa. In other words, the number of prongs in each set may vary and may differ from each other.
[0047] For at least one of the first set and the second set of prongs, the prong neighboring the other set of prongs may be provided with teeth on a side surface thereof, the side surface facing the other set of prongs. In other words, in the first set of prongs, the prong being adjacent to the second set of prongs may be provided with teeth. Additionally or alternatively, the corresponding prong in the second set of prongs, being adjacent to the first set of prongs may also be provided with teeth. Thus, when the handle portion is released in order to grip a food item, the teeth will provide increased friction and a larger contact surface which improves the ability of gripping the food item.
[0048] For example, teeth may be provided on the inner flexible segment of a prong formed as a hollow body in the first set of prongs. Respectively, the inner flexible segment of a prong in the second set of prongs formed as a hollow body may also be provided with teeth. The teeth may be provided on the respective flexible segments such that the teeth face the other set of prongs.
[0049] Additionally or alternatively, the inner flexible segment of a prong in the first set of prongs may have a friction increasing shape. For example, the inner flexible segment may have a zig-zag or wave-like shape. This shape may facilitate gripping of items. The inner flexible segment of the neighbouring prong in the second set of prongs may comprise a complementary zig-zag or wave-like shape such that the prong in the first set of prongs may nest the prong in the second set of prongs.
[0050] A respective second end portion of each member may extend from the second point to a second distal end of the body, the second distal end being opposite to the distal end as seen along the longitudinal axis, the respective second end portion may form a clamping portion and wherein the eating utensil may be further configured such that compression of the handle portion forces the mid portion of the first member towards the mid portion of the second member so as to actuate the clamping portion. Actuating the clamping portion is to be understood as displacing the second end portion of the first member around the second point and from the second end portion of the second member. The clamping portion may be provided with teeth. The teeth provide increased friction and a larger contact surface which improves the ability of gripping food.
[0051] However, it should be understood that the clamping portion may be provided as a pair of prongs. That is, the respective second end portions of each member extending to the second distal end of the body may be a respective prong.
[0052] The clamping utensil may be a surgical utensil. That is, the clamping utensil may be configured for gripping tissue. The surgical utensil may comprise: a body having a longitudinal axis and comprising a first member and a second member extending along said longitudinal axis, wherein at least the first member is flexible, the first and second member being connected at a first point and a second point, the first point being arranged between a distal end of said body and said second point as seen along said longitudinal axis, wherein a respective mid portion of each member extending between said first point and said second point forms a handle portion; and a first set of prongs comprising at least one prong and a second set of prongs comprising at least one prong, the first set of prongs being provided on a respective end portion of the first member and the second set of prongs being provided on a respective end portion of the second member, each set of prongs being provided at the distal end of the body; wherein the surgical utensil is configured such that compression of the handle portion forces the mid portion of the first member towards the mid portion of the second member so as to displace the first set of prongs around the first point and from the second set of prongs.
[0053] Since compression of the handle portion may displace at least the first set of prongs in relation to the second set of prongs, the first point act as a fulcrum facilitating pivoting motion of the first set of prongs. Thus, compression of the handle portion will actuate the surgical utensil by displacing the first set of prongs. Correspondingly, the first set of prongs may return to its initial state when the handle portion is released. Thereby the surgical utensil may grasp or clamp different tissues when the handle portion is released. Thus, less force is required by the user in order to e.g. grip and move tissue with the surgical utensil compared with a conventional utensil.
[0054] The second member of the surgical utensil may also be flexible. Thus, compression of the handle portion forces the respective mid portions of the first member and the second member towards each other so as to displace the first set of prongs and the second set of prongs around the first point and away from each other. Hence, the distance between the first set of prongs and the second set of prongs, created by the pivoting motion around the first point, will be further increased. Thereby tissues that requires a larger space may be received by the clamping device.
[0055] The surgical utensil may be made of a chemically resistant material. Thereby, the surgical utensil may withstand various sterilization treatments. Such sterilization treatments may be at least one of a heat sterilization, a chemical sterilization, and a radiation sterilization. For example, the surgical utensil may be made of, or comprise, materials such as stainless steel, tungsten carbide, polyethylene, polypropylene, polycarbonate or polymethylpentene.
[0056] The surgical utensil may be coated with an antimicrobial coating. For example, the antimicrobial coating may be a parylene coating or a silver plating. Any part or portion of the utensil may be coated with the antimicrobial coating. For example, the prongs may be coated with the antimicrobial coating. Alternatively, the entire utensil may be coated with the antimicrobial coating.
[0057] The first point of the surgical utensil may be distanced from the second point as seen along the longitudinal axis. The mid portion of each member may fully or partially extend between the first and second point. Hence, the handle portion may also fully or partially extend between the first and second point. It is to be understood that the extension of the mid portion and / or the distance between the first point and the second point is to be chosen in relation to the material and material thickness of the members such that compression of the handle portion is feasible.
[0058] The first and second member of the surgical utensil may be connected to each other in a variety of ways. For example, the first and second member may be fixedly connected at the first and / or the second point. More specifically, the first member and the second member may be connected by a living hinge at the first point and / or the second point.
[0059] Alternatively, at the first point and / or the second point, the first member may comprise one of a receiving portion and an engagement portion, and the second member may comprise a complementary receiving portion or engagement portion, wherein the engagement portion may be releasably connected to the receiving portion. The receiving portion may comprise a groove and the engagement portion may comprise a protrusion. Alternatively, the receiving portion may comprise a cutout arranged in a side edge of the respective member, and the engagement portion may comprise a projecting portion arranged on a side edge of the respective member and extending transverse to the longitudinal axis of the body, and wherein the cut-out is provided with a pin-hole and the projecting portion is provided with a pin, the pin extending transverse to the projecting portion and being rotatably arranged in the pin-hole. Furthermore, any member may comprise a cut-out on two opposite side edges. The pin-hole may thus be a through hole, extending from the cut-out in one side edge, to the cut-out of the opposite side edge. Similarly, any member may comprise a first and a second projecting portion arranged on two opposite side edges such that the pin may extend between the projecting portions. Moreover, the pin extending between the projecting portions may be arranged in the through hole.
[0060] The projecting portion may have a semi-circular shape, wherein the cut-out has a shape complementary to the projecting portion.
[0061] The prongs of the first set and the second set of prongs may have a variety of shapes. For example, the at least one prong in the first set of prongs may be formed as a hollow body comprising an inner and an outer flexible segment, wherein the hollow body is configured such that pressing of the outer flexible segment towards the inner flexible segment displaces the inner flexible segment in a bending motion from the second set of prongs.
[0062] The bending motion of the inner flexible segment will cause an actuation of the clamping utensil, the actuation being smaller than the displacement of the prongs caused by compression of the handle portion. Thereby the clamping utensil may be actuated in a precise movement, and is thus suitable for grasping tissues that requires more precision.
[0063] Alternatively the prongs may be tine-shaped. For at least one of the first set and the second set of prongs, the prong neighboring the other set of prongs may be provided with teeth on a side surface thereof, the side surface facing the other set of prongs. In other words, in the first set of prongs, the prong being adjacent to the second set of prongs may be provided with teeth. Additionally or alternatively, the corresponding prong in the second set of prongs, being adjacent to the first set of prongs may also be provided with teeth. Thus, when the handle portion is released in order to grip an item, the teeth will provide increased friction and a larger contact surface which improves the ability of gripping the item.
[0064] For example, teeth may be provided on the inner flexible segment of a prong formed as the hollow body in the first set of prongs. Respectively, the inner flexible segment of a prong in the second set of prongs may also be provided with teeth. The teeth may be provided on the respective flexible segments such that the teeth face the other set of prongs.
[0065] Additionally or alternatively, the inner flexible segment of a prong in the first set of prongs may have a friction increasing shape. For example, the inner flexible segment may have a zig-zag or wave-like shape. This shape may facilitate gripping of items. The inner flexible segment of the neighbouring prong in the second set of prongs may comprise a complementary zig-zag or wave-like shape such that the prong in the first set of prongs may nest the prong in the second set of prongs. A respective second end portion of each member may extend from said second point to a second distal end of the body, said second distal end being opposite to the distal end as seen along the longitudinal axis, the respective second end portions forming a clamping portion and wherein the surgical utensil is further configured such that compression of the handle portion forces the mid portion of the first member towards the mid portion of the second member so as to actuate the clamping portion. The clamping portion may be provided with teeth.
[0066] However, it should be understood that the clamping portion may be provided as a pair of prongs. That is, the respective second end portions of each member extending to the second distal end of the body may be a respective prong.
[0067] The surgical utensil may be one of a hemostat for clamping blood vessels and a tissue clamp for grasping tissue. That is, the surgical utensil may be a hemostat used for temporarily clamp blood vessels to stop bleeding. Alternatively, the surgical utensil may be a tissue clamp for grasping and manipulating tissues during surgical procedures.
[0068] According to a second aspect of the present invention, a kit comprising a first and a second member is provided, wherein at least the first member is flexible, each member on a respective end portion thereof being provided with a respective set of prongs, each set of prongs comprising at least one prong, wherein the first and second member are releasably connectable to each other so as to form a clamping utensil in accordance with the first aspect of the present invention.
[0069] At least some of the technical effect and benefits discussed in relation to the first aspect of the present invention are applicable to the second aspect of the present invention.
[0070] Hereby, the members may, in a disconnected state, be stored and / or transported in a more space-efficient manner. The ability to disconnect the members also makes it possible to replace damaged parts, instead of discarding the whole kit.
[0071] The kit may form an eating utensil when assembled. Here, any member may e.g. be made of, or comprise, metal, wood or polymeric material, such as biodegradable polymeric material. The first member may be made of a first material, and the second member may be made of a second material, the first material being different from the second material. That is, the first member may be made of, or comprise, wood, whereas the second member may be made of, or comprise, metal, or vice versa.
[0072] Alternatively, the kit may form a surgical utensil when assembled. Here, any member may e.g. be made of, or comprise, a metal such as stainless steel or a polymeric material such as polyethylene and polypropylene. The first member may be made of a first material, and the second member may be made of a second material, the first material being different from the second material.

[0085] DETAILED DESCRIPTION
[0086] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, like numbers refer to like elements.
[0087] Fig. 1 is a perspective view of the clamping utensil 1 according to the first aspect of the present invention. Here, the clamping utensil 1 is provided as an eating utensil. The clamping utensil 1 comprises a body 2 having a longitudinal axis. The body 2 comprises a first member 3 and a second member 4. The members 3, 4 extend along the longitudinal axis. The first member 3 and the second member 4 are connected at a first point 5 and a second point 6. The first point 5 is arranged between a distal end 2A of the body 2 and the second point 6 as seen along the longitudinal axis.
[0088] Here, the first member 3 and the second member 4 are integrally formed such that the first member 3 is fixedly connected to the second member 4 at the second point 6. However, the first member 3 is releasably connected to the second member 4 at the first point 5. Exemplary means by which the members 3, 4 are releasably connected to each other are further discussed in relation to Figs. 3 to 6.
[0089] The members 3, 4 further comprises a respective mid portion 3A, 4A, each mid portion 3A, 4A extending between the first point 5 and the second point 6 and forming a handle portion 7. The handle portion 7 is thus comprised of a portion of each member 3, 4, i.e. the respective mid portions 3A, 4A, which are separated from, or otherwise related to, each other such that they may be pressed towards each other. In Fig. 1 , the mid portions 3A, 4A are separated by a gap. However, the mid portions 3A, 4A may be separated by, e.g., compressible material, such as thin, foldable material or dampening material. Here, the two members 3, 4 are separated along a majority of the longitudinal extension of the clamping utensil 1 , and are only connected at the first point 5 and the second point 6. That is, the members 3, 4 are separated from each other between the first point 5 and the distal end 2A.
[0090] The clamping utensil 1 further comprises a first set of prongs 8 and a second set of prongs 9. The first set of prongs 8 is provided at an end portion 3B of the first flexible member 3, wherein the second set of prongs 9 is provided at an end portion 4B of the second flexible member 4. Here, both the first set of prongs 8 and the second set of prongs 9 each comprises two prongs 10. However, the two sets of prongs 8, 9 may comprise different numbers of prongs 10. For example, the first set of prongs 8 may comprise one prong 10, while the second set of prongs 9 comprises two prongs 10, or vice versa. In other words, the number of prongs in each set may vary and may differ from each other. Here, the prongs 10 are arranged next to each other and substantially in a plane. Here, for each set of prongs 8, 9, the prong 10 neighboring the other set of prongs are provided with teeth 11 on a side surface 12 thereof. Each side surface 12 is thereby facing the other set of prongs 8, 9.
[0091] Here, the clamping utensil 1 further comprises a scoop portion 20 extending between the first point 5 and the set of prongs 8, 9. Hereby, the utensil 1 is provided with a curvature as seen transverse to the longitudinal axis of the body 2 so as to facilitate ladling of food items.
[0092] Actuation of the clamping utensil 1 is shown in Fig. 2. The clamping utensil 1 is configured such that compression of the handle portion 7 forces the mid portion 3A of the first member 3 towards the mid portion 4A of the second member 4. Hereby, the first set of prongs 8 is displaced around the first point 5 and from the second set of prongs 9. This is due to at least the first member 3 being flexible. However, as is seen in Fig. 2, the second member 4 may also be flexible. Thus, compression of the handle portion 7 forces the respective mid portions 3A, 4A of the first member 3 and the second member 4 towards each other so as to displace the first set of prongs 8 and the second set of prongs 9 around the first point 5 and away from each other. The clamping utensil 1 may be made of, or comprise, any suitable material, such as metal, wood or polymeric material, such as biodegradable polymeric material. It is to be understood that depending on choice of material or materials, any flexible member 3, 4 is to be dimensioned in a suitable manner. The clamping utensil may have any suitable length, or material thickness. Further, the first and second members 3, 4 may be of equal, or different, lengths. Furthermore, the first and second members 3, 4 may have equal, or different, material thickness. For example, the first member 3 may have a smaller material thickness, i.e. be thinner, than the second member 4, such that the first member 3 is flexible, or at least more flexible than the second member 4. It is to be understood that the clamping utensil 1 may comprise further members, such as a third member. A third member may e.g. be arranged between the first member 3 and the second member 4.
[0093] In Fig. 3, a variant of the clamping utensil 1 is shown. Here, the utensil 1 is provided as a kit comprising a first and a second member 3, 4. Here, the first and second member 3, 4 are releasably connectable to each other so as to form the clamping utensil 1 (shown in Figs 6a, 6b). Here, the second member 4 comprises a first and a second receiving portion 14. The first member 3 comprises a complementary first and a second engagement portion 16. That is, each receiving portion 14 of the second member 4 is to be releasably connected with a complementary respective engagement portion 16 of the first member 3. Hereby, the first member 3 and the second member 4 may be selectively connected and disconnected.
[0094] Here, a respective second end portion 3C, 4C of each member 3, 4 extends to a second distal end 2B of the body 2, the second distal end 2B being opposite to the distal end 2A as seen along the longitudinal axis. The respective second end portions 3C, 4C form a clamping portion 18. Hereby, the clamping utensil 1 is further configured such that compression of the handle portion 7 (shown in Fig. 6b) forces the mid portion 3A of the first member 3 towards the mid portion 4A of the second member 4 so as to actuate the clamping portion 18, which is shown in more detail in Fig. 7.
[0095] The receiving portion 14 and the engagement portion 16 are shown in more detail in Fig. 4. Here, the receiving portion 14 comprises a cut-out 15 arranged in a side edge 17 of the second member 4. The cut-out 15 is provided with a pin-hole 15A. The engagement portion 16 comprises a first and a second projecting portion 19 arranged on a respective side edge 17 of the first member 3 and extending transverse to the longitudinal axis of the body 2. The projecting portions 19 have a semi-circular shape, whereas the cut-out 15 has a shape complementary to the projecting portions 19. Each projecting portion 19 is provided with a pin 19A, the pin 19A extending transverse to the projecting portion 19 and being rotatably arrangeable in a pin-hole 15A of a receiving portion 14. Alternatively to what is shown in Fig. 4, the pin-hole 15A may be a through hole, extending from a cut-out 15 in one side edge 17 of the second member 4 to a cut-out 15 in the opposite side edge 17 of the second member 4. Similarly, the first member 3 may comprise a first and a second projecting portion 16 arranged on two opposite side edges 17 and wherein the pin 19A extends between the two projecting portions 16.
[0096] It is to be understood that the first member 3 may be provided with at least one receiving portion 14, whereas the second member 4 may be provided with at least one engagement portion 16. The first member 3 and the second member 4 may, e.g., be provided with one respective receiving portion 14 and one respective engagement portion 16, each.
[0097] In Fig. 5, a variant of the clamping utensil 1 is shown. In particular, the first member 3 and the second member 4, which are releasably connected at the first point 5, comprise a respective variant of the receiving portion 14 and the engagement portion 16. Here, the first member 3 comprises an engagement portion 16 in the form of a protrusion, whereas the second member 4 comprises a receiving portion 14 in the form of a groove. The protrusion is arranged in the groove.
[0098] In Fig. 6a, a top view of the kit in a disassembled state is shown, whereas in Fig. 6b, a top view of the kit in an assembled state, so as to form an eating utensil 1, is shown.
[0099] In Fig. 7, actuation of the clamping utensil 1 as shown in Figs. 3-4 and 6a and 6b is shown. As can be seen, apart from the displacement of the first set of prongs 8 and the second set of prongs 9 around the first point 5 and away from each other, as has been described in relation to Figs. 1 and 2, the clamping portion 18 is also actuated. Actuation of the clamping portion 18, as shown, entails that the second end portion 3C of the first member 3 is displaced around the second point 6 and from the second end portion 4C of the second member 4. Simultaneously, since both members 3, 4 here are flexible, the second end portion 4C of the second member 4 is displaced around the second point 6 and from the second end portion 3C of the first member 3. Furthermore, the clamping portion 18 is here provided with teeth 21. The teeth 21 provide increased friction and a larger contact surface which improves the ability of gripping items.
[0100] In Fig. 8, a variant of the clamping utensil 1 is shown. Here, the first member 3 and the second member 4 are fixedly connected at the first point 5 and the second point 6 by a living hinge.
[0101] Further, the clamping utensil 1 is provided with a first set of prongs 8 comprising one prong 10, and a second set of prongs 9 comprising one prong 10. Here, the prong 10 in the first set of prongs 8 are arranged against the prong 10 in the second set of prongs 9. Thereby, the clamping utensil 1 may clamp items which otherwise may fall between the prongs.
[0102] Additionally, the clamping utensil 1 in Fig. 8 comprises a clamping portion 18, formed by the respective second end portion 3C, 4C of each member 3, 4 extending to a second distal end 2B of the body 2. Here, the clamping portion 18 is provided as a pair of prongs 10. Thus, the respective second end portions 3C, 4C of each member 3, 4 is shaped as a prong 10.
[0103] In Fig. 9 actuation of the clamping utensil 1 in Fig. 8 is shown. Here it can be seen that compression of the handle portion 7 actuates the clamping portion 18 such that the second end portion 3C shaped like a prong 10 of the first member, and the second end portion 4C shaped like a prong 10 of the second member 4, pivots around the second point 6. Simultaneously, the first set of prongs 8 and the second set of prongs 9 provided at the distal end 2A pivots around the first point 5. Thus the clamping utensil 1 is actuated at both ends during compression of the handle portion 7.
[0104] The prongs 10 in Figs. 8-10 are formed as a hollow body comprising an inner 23 and an outer flexible segment 24. As shown in detail in Fig. 10, the hollow body of the prongs 10 are configured such that if the outer flexible segment 24 is pressed towards the inner flexible segment 23, it will cause the inner flexible segment 23 to bend such that the prongs 10 are slightly bent away from each other. Thereby a second type of actuation is provided by the clamping utensil 1 in Figs. 8-10. The second actuation is smaller than the actuation caused by compression of the handle portion 7. Thereby it is suitable for grasping of items that requires a higher precision.
[0105] Both the first set of prongs 8 and the second set of prongs 9 of the clamping utensil 1 in Figs. 8-10 comprise the above described prong, shaped as a hollow body. However, it should be understood that only one of the first set of prongs 8 and the second set of prongs 9 may comprise this type of prong.
[0106] A surgical utensil may e.g. be embodied as the clamping utensil 1 in Figs. 8- 10. That is, the clamping utensil 1 in Figs. 8-10 may be used for clamping blood vessels or tissues in order to temporarily stop blood flow to control bleedings. The clamping utensil 1 may also be used for grasping and manipulating tissues during surgical procedures and providing precise maximum clamping pressure, thus minimizing potential tissue damage.
