[0048] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0049] The following is combined with Figures 1 to 3 The following describes embodiments of the present invention.

[0050] According to an embodiment of the present invention, a clamping device is provided for clamping a sewing needle. The clamping device includes:

[0051] The clamping body includes a first clamping part and a second clamping part, which are cross-hinged. One end of the first clamping part and the second clamping part are respectively a first clamping end 1 and a second clamping end 2, and the other end of the first clamping part and the second clamping part are respectively a first hand-held end 3 and a second hand-held end 4.

[0052] Magnetic unit 5, provided at the first clamping end 1 and / or the second clamping end 2, is used to attract suture needles;

[0053] The power supply unit is located inside the clamping body and is electrically connected to the magnetic unit 5.

[0054] Control unit 6 is located at the first handheld end 3 and / or the second handheld end 4. One end of control unit 6 is connected to the power supply unit and the other end is connected to the magnetic unit 5. It is used to control the on / off connection between the power supply unit and the magnetic unit 5.

[0055] In the clamping device of this embodiment, by setting a power supply unit inside the clamping body, the clamping device does not need to be connected to an external power source as is the case in related technologies. This avoids the situation where the wire comes into contact with the patient and aggravates the inflammation of the patient's wound, thereby improving the safety of the clamping device during use. At the same time, it also improves the simplicity of the clamping device structure.

[0056] Both the first clamping part and the second clamping part can rotate around the position of the cross hinge.

[0057] In addition, combined Figure 1 As shown, in this embodiment, both the first hand-held end 3 and the second hand-held end 4 are annular structures, which makes the first hand-held end 3 and the second hand-held end 4 suitable for the user's fingers, and further facilitates the user to pass through the first hand-held end 3 and the second hand-held end 4 to drive the rotation of the first clamping part and the second clamping part.

[0058] Of course, in other embodiments, the shapes of the first hand-held end 3 and the second hand-held end 4 can be adjusted according to the needs of the clamping device, for example, the first hand-held end 3 and the second hand-held end 4 can be square.

[0059] Combination Figure 1 As shown, in this embodiment, the magnetic unit 5 is disposed on the first clamping end 1 and the second clamping end 2, and the control unit 6 is disposed on the first hand-held end 3.

[0060] Specifically, in combination Figure 1 As shown, in this embodiment, the control unit 6 is located on the side of the first handheld end 3 away from the second handheld end 4, which makes it easy for the user to take their fingers out of the first handheld end 3 and operate the control unit 6, thereby achieving the technical effect of improving the ease of use of the clamping device.

[0061] Of course, in other embodiments, the positions of the magnetic unit 5 and the control unit 6 can be adjusted according to the different designs of the clamping device. For example, the magnetic unit 5 may be provided only on the first clamping end 1 or only on the second clamping end 2, and the control unit 6 may be provided only on the first hand-held end 3 or only on the second hand-held end 4.

[0062] In addition, combined Figure 1 As shown, in this embodiment, the power supply unit includes:

[0063] Power supply structure 7;

[0064] The first conductor 8 is electrically connected between the power supply structure 7 and the magnetic unit 5;

[0065] The second wire 9 is electrically connected between the power supply structure 7 and the control unit 6;

[0066] The third wire 10 is electrically connected between the control unit 6 and the magnetic unit 5.

[0067] By setting the first wire 8, the second wire 9 and the third wire 10, the power supply structure 7, the control unit 6 and the magnetic unit 5 can be electrically connected so that the magnetic unit 5 can be energized through the power supply structure 7.

[0068] Furthermore, the clamping body is provided with a channel, within which the first wire 8, the second wire 9, and the third wire 10 are all disposed. The channel conceals the first wire 8, the second wire 9, and the third wire 10 within the clamping body, preventing them from being exposed and causing entanglement that would affect the use of the clamping device. This achieves the technical effect of improving the structural simplicity and ease of use of the clamping device.

[0069] Of course, in other embodiments, depending on the design of the clamping device, the first wire 8, the second wire 9, and the third wire 10 can be disposed outside the clamping body, while the first wire 8, the second wire 9, and the third wire 10 are attached to the clamping body, which can also ensure that the first wire 8, the second wire 9, and the third wire 10 do not tangle with each other.

[0070] Furthermore, in this embodiment, combined with Figure 1 As shown, the power supply structure 7 is detachably connected to the clamping body. Therefore, when the power supply structure 7 is low on power, it can be replaced, allowing the clamping device to continue supplying power to the magnetic unit 5, thus ensuring the continuous usability of the clamping device.

[0071] Specifically, the clamping body can have an opening and a cover. For example, the opening can be located at the hinge point between the first clamping part and the second clamping part. The opening is hinged to one end of the cover, and the other end of the cover is detachably connected to the clamping body via a snap-fit. The snap-fit ​​is a mature technology and will not be elaborated on here. Based on this, when it is necessary to replace the power supply structure 7, an external force is used to drive the other end of the cover to rotate around one end of the cover, causing the cover to separate from the snap-fit. The power supply structure 7 is then separated from the clamping body by the external force to replace it with a new power supply structure 7. Then, the external force drives the other end of the cover to rotate around one end of the cover, causing the cover to snap into place with the clamping body, completing the replacement of the power supply structure 7.

[0072] Furthermore, in this embodiment, the power supply structure 7 is a button battery. Of course, in other embodiments, depending on the design of the clamping device, the power supply structure 7 can also be a lithium battery or a rechargeable battery. Compared with other embodiments, the use of a button battery in this embodiment reduces the weight of the power supply structure 7, thereby improving the ease of use of the clamping device.

[0073] Of course, in other embodiments, the power supply structure 7 can be detachably connected to the clamping body via a clamp, or the power supply structure 7 can be fixedly connected to the clamping body. When the power supply structure 7 is low on power, it cannot be replaced, and in this case, the clamping device is only used as scissors. When it is necessary to clamp a sewing needle, it is necessary to replace it with another clamping device with a fully powered power supply structure 7.

[0074] In other embodiments, the power supply structure 7 may be detachably connected to the clamping body, or the power supply structure 7 may be limited to a button battery.

[0075] In addition, in this embodiment, the magnetic units 5 on the first clamping end 1 and the second clamping end 2 are arranged in parallel. Based on this, when the electrical connection between one of the magnetic units 5 on the first clamping end 1 and the second clamping end 2 and the power supply structure 7 fails, the other magnetic unit 5 can still attract the suture needle, thereby achieving the technical effect of improving the reliability of the clamping device.

[0076] Furthermore, the magnetic units 5 on the first clamping end 1 and the second clamping end 2 each include multiple magnetic elements. The multiple magnetic elements on the first clamping end 1 are spaced apart and connected in parallel, and the multiple magnetic elements on the second clamping end 2 are also spaced apart and connected in parallel. Based on this, when one of the multiple magnetic elements in the magnetic unit 5 fails, the magnetic unit 5 can still attract the sewing needle normally, thereby improving the stability of the magnetic unit 5 in fixing the position of the sewing needle and further achieving the technical effect of improving the reliability of the clamping device.

[0077] Specifically, the number of first wires 8 and the number of third wires 10 correspond one-to-one with the number of magnetic components. One end of the magnetic component on the first clamping end 1 is electrically connected to the power supply structure 7 via the first wire 8, and the other end is electrically connected to the control unit 6 via the third wire 10. Similarly, one end of the magnetic component on the second clamping end 2 is electrically connected to the power supply structure 7 via the first wire 8, and the other end is electrically connected to the control unit 6 via the third wire 10.

[0078] Of course, in other embodiments, the circuit structure of the magnetic component can be adjusted depending on the design of the clamping device.

[0079] In other embodiments, depending on the design of the clamping device, the magnetic units 5 on the first clamping end 1 and the second clamping end 2 may be limited to being arranged in parallel, or the magnetic units 5 may be limited to including multiple magnetic elements, which are arranged in parallel.

[0080] In addition, combined Figure 1 and Figure 3As shown, the clamping device includes a guide structure 11, which is disposed on the first hand-held end 3 and the second hand-held end 4, and is used to guide the movement of the first hand-held end 3 and the second hand-held end 4. Therefore, when the first hand-held end 3 and the second hand-held end 4 move, the guide structure 11 can improve the stability of the hinged movement of the first hand-held end 3 and the second hand-held end 4. Alternatively, the guide structure 11 may be disposed only on the first hand-held end 3 or only on the second hand-held end 4, or the clamping device may not include the guide structure 11.

[0081] Specifically, in combination Figure 3 As shown, in this embodiment, the guide structure 11 includes:

[0082] The first guide member 1101 is connected at one end to the second hand-held end 4;

[0083] The second guide 1102 is connected at one end to the other end of the first guide 1101, and the extension direction of the second guide 1102 is different from that of the first guide 1101.

[0084] The third guide 1103 is connected at one end to the first hand-held end 3, and the third guide 1103 is slidably connected to the other end of the second guide 1102.

[0085] The fourth guide 1104 is connected at one end to the other end of the third guide 1103. The fourth guide 1104 extends in a different direction than the third guide 1103. The other end of the fourth guide 1104 is slidably connected to the first guide 1101.

[0086] When the first hand-held end 3 and the second hand-held end 4 approach or move away from each other, the fourth guide 1104 slides along the surface of the first guide 1101, and the second guide 1102 slides along the third guide 1103, so as to achieve the technical effect of improving the stability of the rotation of the first clamping part and the second clamping part.

[0087] Specifically, in combination Figure 3 As shown, the second guide 1102 is perpendicular to the extension direction of the first guide 1101, the fourth guide 1104 is perpendicular to the extension direction of the third guide 1103, the first guide 1101 is parallel to the extension direction of the third guide 1103, and the second guide 1102 is parallel to the extension direction of the fourth guide 1104.

[0088] Of course, in other embodiments, the specific structure of the guide structure 11 can be adjusted according to the different designs of the clamping device. An arc-shaped guide rail is provided on the first hand-held end 3, and the shape of the arc-shaped guide rail is the same as the movement path of the first hand-held end 3 and the second hand-held end 4 hinged together. A sliding groove is provided on the second hand-held end 4, and the arc-shaped guide rail passes through the sliding groove, which can also achieve the technical effect of stabilizing the rotation of the first clamping part and the second clamping part.

[0089] Additionally, the clamping device includes an adjustment unit electrically connected to the power supply unit for adjusting the current flowing through the magnetic unit 5. Based on this, the magnetic strength of the magnetic unit 5 can be adjusted via the adjustment unit to further adjust the attractive force of the magnetic unit 5 on the sewing needle. This allows for adjustment of the magnetic force of the magnetic unit 5 according to actual needs. Alternatively, the clamping device may not include the adjustment unit.

[0090] Preferably, the adjustment unit is located within the control unit 6 and is integrated with the control unit 6. In this case, the control unit 6 can be a rotary switch, which can not only control the on / off state of the circuit between the magnetic unit 5 and the power supply unit, but also adjust the magnitude of the current passing through the magnetic unit 5. This rotary switch is a mature technology and will not be described in detail here.

[0091] Of course, in other embodiments, the adjustment unit can be set separately from the control unit 6. In this case, the type of control unit 6 can be adjusted as needed; for example, the control unit 6 can be a push-button switch, and the adjustment unit can be an adjustable resistor. Push-button switches and adjustable resistors are mature technologies and will not be elaborated upon here. The control unit 6 is driven by external force to adjust the continuity between the magnetic unit 5 and the power supply unit, and the adjustment unit is driven by external force to adjust the current flowing through the magnetic unit 5.

[0092] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
