[0034] Please refer to Figure 1-Figure 6 , this embodiment provides a skin cutting knife 100, the skin cutting knife 100 includes a main body 110, a blade 120 and two hand-held parts 130;
[0035] The main body 110 is provided with a mounting slot 111, and the blade 120 is detachably matched with the mounting slot 111, and the cutting edge of the blade 120 is located outside the mounting slot 111; two hand-held parts 130 are connected to opposite ends of the main body 110, and the mounting slot 111 is located between the two hand-held parts 130;
[0036] The handle 130 is used for the user to operate so as to bend the main body 110 and the blade 120 .
[0037] It should be noted that, in this embodiment, when using the skin cutting knife 100, it can be used directly or bent for use, and the specific use method is determined according to the skin cutting needs at the time.
[0038] Please refer to Figure 1-Figure 6 The working principle of the skin cutting knife 100 is:
[0039] The skin cutting knife 100 includes a main body 110, a blade 120 and two hand-held parts 130; the main body 110 is provided with a mounting slot 111, the blade 120 is detachably matched with the mounting slot 111, and the cutting edge of the blade 120 is located outside the mounting slot 111; the two hand-held parts 130 are connected to opposite ends of the main body 110, and the mounting slot 111 is located between the two hand-held parts 130; wherein the hand-held part 130 is used for the user to operate to bend the main body 110 and the blade 120. The skin cutting knife 100 has a simple structure and is easy to use. It can be held and used by operating the hand-held part 130, thereby improving the safety of use. Moreover, the main body 110 and the blade 120 can be bent by pressing the two hand-held parts 130, thereby controlling the cutting depth and angle of the blade 120, and achieving accurate cutting to the required skin layer.
[0040] Therefore, the steps of using the skin cutting knife 100 are as follows:
[0041] First, install the blade 120 into the installation slot 111 and ensure that the cutting edge of the blade 120 is located outside the installation slot 111;
[0042] Then, in the process of operating the skin cutter 100 to cut the skin position corresponding to the buffer, the user can press the two handles 130 with his hands to bend the main body 110 and the blade 120 installed on the main body 110. Therefore, the cutting depth and angle of the blade 120 can be controlled by controlling the bending degree of the blade 120, so as to achieve accurate cutting to the required skin layer.
[0043] For further information, please refer to Figure 1-Figure 6 In the present embodiment, when configuring the hand-held part 130, it should be noted that the present embodiment is described by taking the hand-held part 130 for the user to hold and operate as an example, while in other embodiments of the present invention, the hand-held part 130 can also be used in conjunction with other medical devices.
[0044] Moreover, in the present embodiment, when configuring the hand-held portion 130, the two hand-held portions 130 are both protruded toward one side of the main body 110. With this arrangement, when operating the hand-held portion 130, the user can apply external force to the two hand-held portions 130, thereby making the two hand-held portions 130 approach each other, thereby making the blade 120 and the main body 110 located between the two hand-held portions 130 bend, and the degree of bending is determined by the external force applied to the hand-held portion 130 by the user. Moreover, in the process of configuring the hand-held portion 130, the main body 110 is arranged in such a way that it protrudes in a direction away from the hand-held portion 130, that is, the protrusion of the bent main body 110 is opposite to the protrusion direction of the hand-held portion 130. In this way, the cutting depth and angle of the blade 120 can be controlled by controlling the bending degree of the blade 120, so as to achieve precise cutting to the required skin layer.
[0045] On the basis of the above contents, since the skin cutting knife 100 provided in this embodiment can control the cutting depth and angle of the blade 120 by bending during use, based on this, in order to reduce the bending resistance during the bending of the main body 110 and the blade 120, the main body 110 is provided with a clearance groove 112, and the clearance groove 112 is connected to the mounting groove 111. By setting the clearance groove 112, the bending resistance of the main body 110 can be reduced, so that the skin cutting knife 100 can be easily bent for use. Moreover, it can be known from the above contents that the bending form of the main body 110 is to bend and bulge in the direction away from the handheld part 130. Therefore, the present embodiment adopts the method of making the clearance groove 112 and the handheld part 130 located on the same side of the main body 110, thereby reducing the bending resistance of the main body 110 and the handheld part 130 located on the same side.
[0046] For further information, please refer to Figure 1-Figure 7 In this embodiment, in order to limit the curvature of the main body 110 during the bending process to avoid damage to the main body 110 or the blade 120 due to excessive curvature, the skin cutting knife 100 further includes a bending block 140, which is detachably connected to the main body 110 and is used to limit the bending deformation of the main body 110 under the action of external force. Specifically, when the bending block 140 is installed, the way in which the clearance groove 112 is directly opposite to the bending block 140 and a part of the bending block 140 is accommodated in the clearance groove 112 is adopted, and the bending block 140 extends from one of the handheld parts 130 to the other handheld part 130.
[0047] In order to make the bending block 140 limit the maximum bending degree of the main body 110 and prevent the bending block 140 from affecting the bending action of the main body 110 within the normal bending range, the bending block 140 is provided with a plurality of grooves 141, and the plurality of grooves 141 penetrate the bending block 140 in a direction perpendicular to the extension direction of the bending block 140. Thus, in this way, the bending block 140 can be deformed during the bending process of the main body 110, and during the deformation process of the bending block 140, since the grooves 141 are provided, the two sides of the grooves 141 can be brought close to each other, thereby reducing the bending resistance of the bending block 140, thereby preventing the bending block 140 from affecting the bending action of the main body 110 within the normal bending range.
[0048] When the groove 141 is formed, in order to make the deformation direction of the groove 141 during the deformation process conform to the bending direction of the main body 110, the opening of the groove 141 is located on the side of the bending block 140 away from the main body 110, and the groove 141 is a triangular groove or a wedge-shaped groove. In addition, when the groove 141 is configured, the plurality of grooves 141 include a plurality of first grooves 142 and a plurality of second grooves 143, the groove depth of the first groove 142 is greater than the groove depth of the second groove 143, and along the extension direction of the bending block 140, the plurality of first grooves 142 and the plurality of second grooves 143 are arranged in a staggered order.
[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
