DETAILED DESCRIPTION

[0017] The technical scheme in the utility model will be further explained below in combination with the drawings and embodiments.

[0018] As Figure 1 With Figure 2As shown, the utility model discloses an electric knife auxiliary suction pipe, which comprises an electric knife body 100, a mounting assembly, a clamp 5 detachably mounted on the electric knife body 100 and a guide cylinder 4 fixedly arranged on the clamp 5, wherein a limiting hole 402 coaxial with the axis of the guide cylinder 4 is formed at the connecting position of the guide cylinder 4 and the clamp 5; a suction member comprising a guide pipe 2 movably arranged in the guide cylinder 4 and a limiting shaft 205 slidably arranged in the limiting hole 402, wherein the limiting shaft 205 is fixedly connected with the guide pipe 2 at both ends, and the guide pipe 2 is used for sucking away smoke and liquid in the gap; and a columnar nut 3 threadedly connected with the guide pipe 2 and used for driving the guide pipe 2 to move forward and backward along the axis of the guide cylinder 4.

[0019] The detailed working process of the embodiment is as follows: the limiting shaft 205 is fixedly connected with the guide pipe 2 at both ends and can slide in the limiting hole 402, and under the arrangement of the limiting shaft 205, the guide pipe 2 is prevented from rotating during the movement of the guide pipe 2 driven by rotating the columnar nut 3.

[0020] By mounting the guide pipe 2 with adjustable distance on the electric knife body through the clamp 5, the guide pipe 2 is adjusted to move forward or backward by rotating the columnar nut 3 in forward and reverse directions, so as to approach or move away from the operation position, and meanwhile, the guide pipe 2 can be adjusted to the appropriate position and kept due to the thread connection between the columnar nut 3 and the guide pipe 2, so that the guide pipe 2 does not need to be controlled for a long time and the user does not need to exert external force to control the guide pipe 2, thereby improving the operation efficiency.

[0021] As shown in the figure, Figure 2 The guide pipe 2 comprises a first suction pipe 201 and a second suction pipe 202 fixedly connected at one end of the first suction pipe 201, the second suction pipe 202 is arranged at an angle of 160°-170° with the first suction pipe 201 near the electric knife body 100, the first suction pipe 201 is provided with threads, and a hose 204 is connected at the end of the first suction pipe 201 away from the second suction pipe 202.

[0022] The detailed working process of the embodiment is as follows: the first suction pipe 201 and the second suction pipe 202 are connected at an angle of 160°-170°, and the angle is 165° in the embodiment, in this state, the end of the second suction pipe 202 can approach the operation position, and the smoke generated during the operation can be sucked away as far as possible to avoid its spread and affect the vision, and the other end of the first suction pipe 201 is connected with the hose 204, and the hose 204 is connected with an external negative pressure equipment, so as to perform negative pressure adsorption work.

[0023] As shown in the figure, Figure 2 The middle part of the guide cylinder 4 is formed with a notch 401, the columnar nut 3 is located at the notch 401, and the columnar nut 3 is threadedly connected with the first suction pipe 201.

[0024] The detailed working process of this embodiment is that the columnar nut 3 is located at the gap 401, the gap 401 limits the columnar nut 3, so that the columnar nut 3 can only rotate at the gap 401 and cannot be displaced, thereby rotating the columnar nut 3 to drive the first suction pipe 201 to move.

[0025] As shown in Figure 2 The columnar nut 3 is provided with a knurled pattern 301.

[0026] The detailed working process of this embodiment is that the knurled pattern 301 increases the friction of the columnar nut 3, which can provide better operation feeling and anti-skid effect.

[0027] As shown in Figure 2 The clamp 5 includes two first and second arc-shaped seats 501 and 502 that are hingedly connected to each other, wherein the second arc-shaped seat 502 is rotatably provided with a bolt 503 at an end away from the hinge point, and the bolt 503 is threadedly connected with the first arc-shaped seat 501.

[0028] The detailed working process of this embodiment is that the first and second arc-shaped seats 501 and 502 are hingedly connected, which facilitates disassembly and improves the use range. When disassembling, the bolt 503 is loosened to make the second arc-shaped seat 502 separate from the first arc-shaped seat 501, and then the clamp 5 can be disassembled.

[0029] As shown in Figure 2 The inner arc surfaces of the first and second arc-shaped seats 501 and 502 are provided with rubber pads 504.

[0030] The detailed working process of this embodiment is that the rubber pads 504 increase the friction between the first and second arc-shaped seats 501 and 502 and the electrotome body 100, thereby preventing the first and second arc-shaped seats 501 and 502 from sliding off and preventing the first and second arc-shaped seats 501 and 502 from directly and rigidly contacting the electrotome body 100 to cause wear of the electrotome body 100.

[0031] As shown in Figure 2 The first and second suction pipes 201 and 202 are made of hard transparent material.

[0032] The detailed working process of this embodiment is that the transparent material has low refractive index and high transparency, so that the flow of the medium in the pipe can be directly observed, which is convenient for monitoring and inspection.

[0033] The principle of the embodiment is that the first and second arc-shaped seats 501 and 502 are clamped on the electrotome body 100, and the hose 204 at one end of the first suction pipe 201 is connected to an external negative pressure device. When in use, the medical staff can adjust the guide pipe 2 by finger poking the knurled pattern 301 to perform the adsorption work.

[0034] Finally, it is explained that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the present application. The technical solutions of the present application should be covered in the scope of the claims of the present application.
