[0040] As shown in Figures 1 to 3 The present embodiment provides a low-temperature plasma ablation electrode used with an endoscopic surgery shaver, which comprises a handle 100, a sleeve 200, an end cap 300, a mounting seat 400 and a sub-needle 500. The distal end and the proximal end of the handle 100 are respectively provided with a first connecting portion and a second connecting portion, and the proximal end of the sleeve 200 is detachably connected to the first connecting portion. The end cap 300 is arranged at the distal end of the sleeve 200, i.e. the end away from the first connecting portion. The mounting seat 400 is arranged at the end of the end cap 300 away from the sleeve 200. The sub-needle 500 is connected to the mounting seat 400 and at least partially protrudes from the end of the mounting seat 400 away from the end cap 300.

[0041] With the above structure, after the front operation is completed, the sleeve 200 can be detached from the handle 100 and discarded together with the end cap 300, the mounting seat 400 and the sub-needle 500. A new sleeve 200, end cap 300, mounting seat 400 and sub-needle 500 are replaced to avoid discarding the reusable handle 100, thereby reducing the cost and medical waste.

[0042] To improve the disassembly efficiency, in some embodiments, the first connecting portion is a plug-in slot 111 formed in the handle 100, and the sleeve 200 is detachably plugged into the plug-in slot 111 along the axial direction of the sleeve 200. Before the operation, only the sleeve 200 with the sub-needle 500 needs to be plugged into the plug-in slot 111, and after the operation, the sleeve 200 is directly pulled out of the plug-in slot 111 and discarded together with the sub-needle 500, and the handle 100 can be reused. It should be noted that when the sleeve 200 is plugged into the plug-in slot 111, the sub-needle 500 is connected to the circuit board in the sleeve 200, and after the circuit board in the handle 100 is connected to the main machine, the sub-needle 500 can be provided with power energy and control signals. The working principle of the sub-needle 500 is well known to those skilled in the art and does not belong to the key content of the present application, so it will not be described in detail.

[0043] During the operation, the sleeve 200 needs to be inserted into the patient's body, which can be used for cutting and ablation treatment of tissues at the knee, hip, shoulder, ankle, elbow, and radial joint. To avoid damage to other irrelevant surgical soft tissues such as cartilage tissue and ligament during the insertion process, in some embodiments, the end cap 300 is an arc-shaped structure for fitting the patient's bone tissue. The central angle of the end cap 300 is 30°-60°. For example, the central angle of the end cap 300 is 45°. This angle is beneficial for the doctor's operation to adapt to more operation positions as much as possible.

[0044] In some embodiments, the end cap 300 and the sleeve 200 are integrally formed to improve the connection strength.

[0045] The handle 100 includes a holding body 110 having a receiving groove and a rear end cover 120 arranged on the holding body 110 and sealing the opening of the receiving groove to form a receiving cavity. The low-temperature plasma ablation electrode used in cooperation with the endoscopic surgical shaver further includes a detection piece 130 arranged in the receiving cavity, which is used to detect the energy output by the sub-needle 500. A plug-in groove 111 is arranged at one end of the holding body 110 away from the rear end cover 120. The detection piece 130 is arranged on a circuit board. This arrangement allows the circuit board and the detection piece 130 to be located in the sealed receiving cavity, avoiding moisture and improving detection accuracy and service life. Further, the end of the holding body 110 towards the rear end cover 120 is provided with a first annular groove surrounding the outer periphery of the receiving groove, and the end of the rear end cover 120 towards the holding body 110 is provided with a second annular groove opposite the opening of the first annular groove. When the rear end cover 120 is arranged on the holding body 110, the first annular groove and the second annular groove form an annular cavity, and the sealing ring is located in the annular cavity and is compressed to achieve sealing of the receiving cavity. The outer peripheries of the holding body 110 and the rear end cover 120 are insulated to prevent electric leakage.

[0046] In some embodiments, the rear end cover 120 includes an end cover body 121 and a plug-in portion 122. The second connecting portion is arranged on the end cover body 121, the outer diameter of the plug-in portion 122 is equal to the diameter of the receiving groove, and the outer diameter of the end cover body 121 is greater than the diameter of the receiving groove. The plug-in portion 122 is plugged into the receiving groove. The second annular groove is arranged on the end cover body 121. The side wall of the receiving groove is provided with a limiting protrusion extending along the axial direction of the handle 100, and the side wall of the plug-in portion 122 is provided with a limiting groove 123 corresponding to the limiting protrusion. The limiting protrusion is plugged into the limiting groove 123. The side wall of the receiving groove is provided with three limiting protrusions spaced apart around the axial direction of the handle 100, and the side wall of the plug-in portion 122 is provided with three limiting grooves 123. The three limiting protrusions are respectively plugged into the three limiting grooves 123.

[0047] In order to facilitate operation, in some embodiments, the handle 100 further comprises a cable 600 connected to the second connecting portion of the rear end cover 120 and used for connecting with the main machine. The cable 600 is arranged to enable the handle 100 to be moved at will to facilitate the operation while realizing the electrical connection and / or communication connection between the handle 100 and the main machine. The proximal end of the cable 600 is provided with a quick plug for facilitating plugging with the socket of the main machine.

[0048] After the operation is completed, the sleeve 200 needs to be detached from the handle 100 and discarded, and then the handle 100 and the cable 600 are sterilized and disinfected to prepare for subsequent use. The handle 100 and the cable 600 can be sterilized by using low-temperature plasma or by using high temperature and high pressure.

[0049] In the endoscopic surgery, it is necessary to minimize the damage to the human tissue, so it is necessary to perform a small incision operation. Regarding the diameter of the sleeve 200, in some embodiments, the diameter of the sleeve 200 is 2.5mm-4.6mm. The length of the sleeve 200 is 12mm-19mm. The length is moderate and ergonomic, which facilitates ablation operation in various postures during the operation and improves the operation efficiency. At the same time, it is beneficial to postoperative recovery and reduces infection and other complications. The outer periphery of the sleeve 200 has an insulating layer to avoid electric leakage and thus avoid injury to the participants in the operation.

[0050] In order to ensure the operation precision, in the first embodiment of the present embodiment, the length of the sub-needle 500 is 2mm-4mm. In the second embodiment of the present embodiment, the diameter of the sub-needle 500 is 0.15mm-0.55mm. In the third embodiment of the present embodiment, the length of the sub-needle 500 is 2mm-4mm; and the diameter of the sub-needle 500 is 0.15mm-0.55mm.

[0051] The sub-needle 500 is made of tantalum or stainless steel and has an insulating layer on the outer periphery to avoid electric leakage and thus avoid injury to other tissues outside the operation position. The mounting seat 400 has at least six sub-needles 500, which can work simultaneously to improve the work efficiency or work individually to improve the operation precision. The six sub-needles 500 are arranged uniformly around the axial direction of the mounting seat 400.

[0052] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and replacements can be made without departing from the protection scope of the present application. Here, it is not necessary and also impossible to enumerate all the implementation modes. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application claim.
