[0037] Example 1

[0038] refer to Figure 1, the figure shows a plasma costal cartilage cutting device 100 provided in this embodiment, which is mainly used in medical cosmetic procedures where a portion of the costal cartilage needs to be removed and peeled off for other uses.

[0039] In some embodiments, a pulverizing blade is used to cut the costal cartilage. After cutting, the costal cartilage in vivo has a poor shape and the cutting speed is relatively slow. Therefore, the present application proposes a solution for cutting using plasma. Obviously, the plasma costal cartilage cutting can be used in other occasions in the field, such as shallow wound cleaning.

[0040] Also refer to Figure 2 Specifically, the plasma rib cartilage cutting device 100 includes a main body 110, a plasma cutting unit 120, and a water pipe 130. A limiting electrode plate 132 is provided at one end of the water pipe 130 close to the plasma cutting unit 120; and a water outlet hole 134 is opened on the limiting electrode plate 132.

[0041] It should be noted that the limiting electrode plate 132 can provide a limiting effect, and its cross-sectional shape can be circular, rectangular, long strip or other shapes. Similarly, the water outlet hole 134 can be a circular hole, a strip hole or a water outlet hole 134 composed of multiple small holes.

[0042] The plasma cutting part 120 is disposed at one end of the main body 110; the plasma cutting part 120 includes a first electrode body 122, a second electrode body 124, and an electrode wire 126 whose two ends are respectively connected to the first electrode body 122 and the second electrode body 124. The first electrode body 122 and the second electrode body 124 are the electrode cathode and the anode, respectively, and the electrode wire 126 is driven by the electrode body to perform plasma cutting.

[0043] In some embodiments, preferably, the diameter of the electrode wire 126 does not exceed 0.2 mm, such as 0.18 mm or 0.15 mm, etc. In this embodiment, the electrode wire 126 is a tungsten wire with a diameter of 0.2 mm.

[0044] In some embodiments, the first electrode body 122 and the second electrode body 124 are ceramic electrodes.

[0045] The electrode plate, the first electrode body 122, the second electrode body 124 and the electrode wire 126 form a cutting space; the water outlet 134 is opened toward the cutting space. The water outlet 134 can provide cooling and cleaning effects to a certain extent.

[0046] More specifically, the cutting space is used for cutting and stripping of the costal cartilage. The costal cartilage that is usually required is in sheet form, and the limiting electrode plate 132 is in contact with the outer side of the costal cartilage. At the same time, the electrode wire 126 is cut to ensure that the thickness is controllable. On the one hand, it will not cause excessive cutting of the costal cartilage, and on the other hand, it avoids the possibility of damage to surrounding tissues.

[0047] Furthermore, the angle between the extending direction of the first electrode body 122 and the second electrode body 124 and the limiting electrode plate 132 is 90 degrees, and the angle between the front direction of the electrode wire 126 and the extending direction of the main body 110 is 45 degrees. This angle setting method facilitates the operation of the surgery and the observation of the surgical area.

[0048] Optionally, in some other specific embodiments, the limiting electrode plate 132 is rotatably connected to one end of the water outlet pipe 130; the extension direction of the first electrode body 122 and the second electrode body 124 forms a variable angle of 45 to 90 degrees with the limiting electrode plate 132, so as to increase the application range of the plasma costal cartilage cutting device 100 in this way.

[0049] In some embodiments, the required thickness of the costal cartilage may be different depending on the surgical situation or the condition of the patient undergoing the surgery. Therefore, the thickness of the cut and peeled costal cartilage is controlled by adjusting the limiting electrode plate 132 .

[0050] refer to Figure 3 In some embodiments, the main body 110 includes an adjusting part 112 and a transmission part; the transmission part includes a screw rod 114 and a sleeve 116 connected in a transmission manner; the limit electrode plate 132 is connected to the sleeve 116; the adjusting part 112 is connected to the screw rod 114; the sleeve 116 is configured to drive the limit electrode plate 132 to extend and retract along the length direction of the main body 110 under the control of the adjusting part 112. That is, the limit electrode plate 132 can be extended and retracted by the user rotating the transmission part in different directions, thereby controlling the size of the cutting space (the distance between the limit electrode plate 132 and the electrode wire 126) to obtain rib cartilages of different thicknesses.

[0051] Preferably, the adjusting portion 112 is disposed at one end of the main body 110 away from the plasma cutting portion 120. In other specific embodiments, it can also be disposed on the side of the main body 110. In addition, in some other embodiments, the transmission portion can also be a worm gear transmission, a gear transmission, or a motor transmission.

[0052] In some embodiments, in order to adapt to different cutting positions, the plasma cutting part 120 is further connected to the sliding sleeve 116; the sliding sleeve 116 is configured to drive the plasma cutting part 120 and the limiting electrode plate 132 to extend and retract along the length direction of the main body 110 under the control of the adjusting part 112. In this way, the cutting of the rib cartilage at different positions is achieved. It should be noted that in some embodiments, two sets of adjusting parts 112 and transmission parts can also be provided to adapt to the cutting of rib cartilage at different positions and different thicknesses.

[0053] The present application provides a plasma costal cartilage cutting device 100, which utilizes plasma to achieve good cutting and peeling effects. Meanwhile, the setting of the limiting electrode plate 132 can ensure the controllable cutting thickness and avoid damaging other tissues. In addition, costal cartilages of different thicknesses can be obtained through adjustment. The device has strong adaptability and has a promising prospect for promotion.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have 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.
