The elastic bending member is partially disposed in the mounting cavity in a preset bent state. The elastic bending member has a second connecting portion located at its end and a pressing portion spaced apart from the second connecting portion. The second connecting portion protrudes to the outside of the connector body through the mounting through hole to connect with the first connecting portion. The pressing portion protrudes to the outside of the connector body through the operation through hole. When the pressing portion is subjected to force and moves toward the mounting cavity, the second connecting portion moves toward the mounting cavity to separate from the first connecting portion.
[0012] In one embodiment, the length of the pressing portion protruding from the plug body is greater than or equal to the length of the second connecting portion protruding from the plug body.
[0013] In one embodiment, the pressing part is located outside the cable interface, and when the second connecting part is connected to the first connecting part, the pressing part abuts against the open end of the cable interface.
[0014] In one embodiment, the tool housing is provided with an installation channel for mounting the tool assembly and a set of sockets for connecting the cable interface and the installation channel; the connector further includes a conductive component, a portion of which is inserted into the set of sockets and abuts against the tool assembly to be electrically connected to the electrode, and another portion of which is located in the mounting cavity and is laterally spaced from the second connecting portion.

[0030] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0031] Radiofrequency powered surgical instruments are surgical tools that combine radiofrequency ablation technology with power drive. They can not only use motors or other power sources to perform operations such as planing, grinding, sawing, milling, or drilling, but also achieve electrocoagulation hemostasis via radiofrequency electrodes. Traditional radiofrequency powered surgical instruments are usually integrated with their cables; when the instrument needs to be replaced, the cable must be replaced simultaneously, increasing the cost of using the device. For example... Figure 1 and Figure 2 As shown, in one embodiment, a power radio frequency device is provided, including a host (not shown) and a radio frequency power cutter 10, wherein the host is electrically connected to the radio frequency power cutter 10, thereby providing high-frequency power for the radio frequency cutting and electrocoagulation hemostasis functions of the radio frequency power cutter 10.
[0032] It should be noted that the host computer can be an existing component, which will not be elaborated further here.
[0033] Optionally, the main unit may include a separately configured power main unit and an RF main unit, with the power input of the RF power tool 10 connected to the power main unit and the RF energy input connected to the RF main unit. The main unit may also include an integrated main unit that combines power and RF.
[0034] like Figures 1 to 3 As shown, in one embodiment, a radio frequency powered cutting tool 10 is provided, including a cutting tool assembly 100 with electrodes, a cutting tool housing 200, and a connecting cable 300.
[0035] The tool assembly 100 may include an inner tool tube and an outer tool tube that are nested together. Since this may be considered prior art, it will not be described in detail here.
[0036] like Figure 3 and Figure 5 As shown, the tool housing 200 is sleeved on the outer wall of the tool assembly 100, for example, the tool housing 200 is sleeved on the outer wall of the outer tool tube. The outer peripheral side of the tool housing 200 is provided with a cable interface 210, and the inner side wall of the cable interface 210 is provided with a first connecting part 211.
[0037] like Figure 3 As shown, in one embodiment, a cable interface 210 is provided on the lower side wall of the tool housing 200. The cable interface 210 has a plug structure with an opening at the bottom, and a first connecting part 211 is provided on the left and right side walls of the cable interface 210.
[0038] like Figure 2 , Figure 3 and Figure 6 As shown, one end of the connecting cable 300 is provided with a connecting plug 310, which is partially inserted into the cable interface 210 and electrically connected to the electrodes of the tool assembly 100. Furthermore, the connecting plug 310 is provided with a second connecting portion 311 that is detachably connected to the first connecting portion 211.
[0039] In one embodiment, the connector 310 is partially inserted into the cable interface 210 so that the second connector 311 is connected to the first connector 211. At this time, the connector 310 is electrically connected to the tool assembly 100, and the other end of the connector cable 300 is electrically connected to the host. The connector cable 300 enables the tool assembly 100 to be electrically connected to the host, so that the tool assembly 100 can be powered on to perform radio frequency cutting and electrocoagulation hemostasis.
[0040] It should be noted that power can be supplied to the inner and outer blade tubes separately to form a circuit through the connector 310 of the connecting cable 300, or power can be supplied to the outer blade tube alone to form a circuit, as long as it can be used to perform radiofrequency ablation and electrocoagulation hemostasis on the affected area.
[0041] In the radio frequency powered cutting tool 10 of the above embodiment, the connector 310 is inserted into the cable interface 210, so that the second connecting part 311 is connected to the first connecting part 211, thereby realizing the assembly connection between the connecting cable 300 and the cutting tool housing 200, and making the connector 310 electrically contact the cutting tool assembly 100, thereby enabling the electrical connection between the cutting tool assembly 100 and the host through the connecting cable 300. When it is necessary to replace the cutting tool assembly 100 and the cutting tool housing 200, it is only necessary to separate the second connecting part 311 from the first connecting part 211 to replace the cutting tool assembly 100 and the cutting tool housing 200 separately, without having to replace the connecting cable 300 at the same time, thus reducing the cost of using the instrument. Furthermore, the plug-and-play assembly of the connector 310 and the cable interface 210 to achieve electrical connection with the cutting tool assembly 100 is simple, convenient, and easy to operate.
[0042] The detachable connection between the first connecting part 211 and the second connecting part 311 can be achieved by plugging in, snapping in, or screwing in.
[0043] like Figure 4 As shown, in one embodiment, the first connecting part 211 is provided with a slot 2111, and the second connecting part 311 is provided with a buckle 3111 that engages with the slot 2111. Thus, by utilizing the engagement between the buckle 3111 and the slot 2111, the connecting plug 310 and the tool housing 200 are assembled and connected. Assembly is simple and convenient. Furthermore, the connecting plug 310 and the tool housing 200 can be separated simply by separating the buckle 3111 from the slot 2111, facilitating operation.
[0044] like Figure 3 As shown, in one embodiment, the cable interface 210 has a first guide slope 212 on the opening sidewall, so that the opening of the cable interface 210 is flared, which facilitates the insertion of the connector 310 and makes operation easier.
[0045] like Figure 3 As shown, in one embodiment, the buckle 3111 is provided with a second guide slope 312 facing the outer side wall of the tool housing 200, so that the buckle 3111 can be inserted into the cable interface 210 and engage with the slot 2111, making insertion and removal smooth and easy to operate.
[0046] like Figure 3 and Figure 7As shown, in one embodiment, the connector 310 includes a connector body 313 and an elastic bending member 314. The connector body 313 has a mounting cavity 3131, a mounting through hole 3132 communicating with the mounting cavity 3131, and an operation through hole 3133 spaced apart from the mounting through hole 3132 and communicating with the mounting cavity 3131. Specifically, the mounting through hole 3132 and the operation through hole 3133 are spaced apart along the insertion / removal direction of the connector 310. The elastic bending member 314 is partially disposed in the mounting cavity 3131 in a preset bent state. The elastic bending member 314 has a second connecting portion 311 located at its end and a pressing portion 3141 spaced apart from the second connecting portion 311. Furthermore, the second connecting part 311 protrudes to the outside of the plug body 313 through the mounting through hole 3132 to connect with the first connecting part 211. Thus, after the plug body 313 is inserted into the cable interface 210, the second connecting part 311 is connected with the first connecting part 211. For example, the buckle 3111 engages with the slot 2111, thereby enabling the plug body 313 to be assembled and connected with the tool housing 200, and thus achieving electrical contact with the tool assembly 100. Meanwhile, the pressing part 3141 protrudes to the outside of the plug body 313 through the operation through hole 3133. When the pressing part 3141 is subjected to force and moves toward the mounting cavity 3131, the second connecting part 311 moves toward the mounting cavity 3131 to separate from the first connecting part 211. Thus, when the pressing part 3141 is pressed and displaced along the operation through hole 3133 toward the mounting cavity 3131, the second connecting part 311 can be moved along the mounting through hole 3132 toward the mounting cavity 3131, thereby separating the second connecting part 311 from the first connecting part 211. This allows the plug body 313 to be pulled out of the cable interface 210, thus separating the connector plug 310 from the tool housing 200.
[0047] It should be noted that the insertion and removal direction of connector 310 (e.g.) Figure 3 The EF direction refers to the direction in which the connector 310 is inserted into and removed from the cable interface 210.
[0048] The preset bending state of the elastic bending component 314 can be U-shaped, V-shaped, or W-shaped.
[0049] The central axis of the mounting through hole 3132 and the central axis of the operating through hole 3133 can both be perpendicular to the insertion and removal direction of the connector 310.
[0050] The pressing part 3141 can be in the form of a protruding button or a boss.
[0051] like Figure 4 As shown, optionally, the length of the pressing part 3141 protruding from the plug body 313 (e.g.) Figure 4(As shown in D1) is greater than or equal to the length of the second connecting part 311 protruding from the plug body 313 (e.g.) Figure 4 (As shown in D2). Thus, pressing the pressing part 3141 causes it to move along the operating through hole 3133 toward the mounting cavity 3131, which in turn moves the second connecting part 311 along the mounting through hole 3132 toward the mounting cavity 3131 until the second connecting part 311 separates from the first connecting part 211. At this time, the pressing part 3141 protrudes at least partially to the outside of the plug body 313, preventing the elastic bending member 314 from separating from or falling off the plug body 313, thus ensuring the reliability of the assembly.
[0052] like Figure 4 As shown, in one embodiment, the pressing part 3141 is located outside the cable interface 210, which facilitates applying force to the pressing part 3141. Furthermore, when the second connecting part 311 is connected to the first connecting part 211, the pressing part 3141 abuts against the open end of the cable interface 210. This abutting action between the pressing part 3141 and the open end of the cable interface 210 limits the insertion of the connector 310 into the cable interface 210 and also positions the connection between the first connecting part 211 and the second connecting part 311, improving assembly accuracy.
[0053] like Figure 3 As shown, in one embodiment, the tool housing 200 is provided with a mounting channel 220 for mounting the tool assembly 100 and a socket group 230 for connecting the cable interface 210 and the mounting channel 220. Thus, the tool housing 200 is fitted onto the outer wall of the tool assembly 100 through the mounting channel 220 to achieve assembly connection. Furthermore, the connector 310 also includes a conductive component (not labeled). One part of the conductive component is inserted into the socket group 230 and abuts against the tool assembly 100 to connect with the electrodes of the tool assembly 100. The other part of the conductive component is located in the mounting cavity 3131 and is laterally spaced from the second connecting portion 311. In this way, electrical energy from the host is transmitted to the tool assembly 100 through the conductive component and forms a circuit through human tissue, enabling the tool assembly 100 to perform operations such as radiofrequency ablation and electrocoagulation hemostasis after being energized.
[0054] Among them, horizontal (such as) Figure 3 The MN direction can be perpendicular to the insertion / removal direction.
[0055] Furthermore, the distance between the conductive component and the second connection portion 311 is the first distance (e.g., Figure 4 As shown in D3), the second connecting part 311 protrudes beyond the length of the plug body 313 (as shown in Figure D3). Figure 4As shown in D2, the first length is the first spacing, which is adapted to the first length. Thus, the second connecting part 311 moves along the mounting through hole 3132 toward the mounting cavity 3131 under the action of the pressing part 3141. When the second connecting part 311 is fully retracted into the mounting through hole 3132, the side of the second connecting part 311 near the conductive component abuts against the conductive component and cannot continue to move toward the mounting cavity 3131. This not only ensures that the second connecting part 311 can be completely separated from the first connecting part 211, but also ensures that the pressing part 3141 cannot continue to move along the operating through hole 3133 toward the mounting cavity 3131, thus preventing the elastic bending member 314 from separating from or falling off the plug body 313.
[0056] The specific dimensions of the first spacing and the first length can be flexibly adjusted or designed according to actual design requirements or usage requirements, and no specific restrictions are imposed here.
[0057] like Figure 3 As shown, the cutting tool assembly also has two electrodes; the conductive assembly includes a first conductive element 315 and a second conductive element 316 arranged laterally at relative intervals. The first conductive element 315 and the second conductive element 316 are both disposed between the two ends of the elastic bending member 314. Both the first conductive element 315 and the second conductive element 316 can make electrical contact with the cutting tool assembly 100 to connect electrically to the two electrodes respectively and form a circuit through human tissue. Thus, current flows through the first conductive element 315, the cutting tool assembly 100, and the second conductive element 316 to form a circuit, enabling the cutting tool assembly 100 to perform operations such as radiofrequency ablation and electrocoagulation hemostasis after being energized. Furthermore, the distance between the first conductive member 315 and the corresponding second connecting portion 311 is equal to the distance between the second conductive member 316 and the corresponding second connecting portion 311. In a specific embodiment, the elastic bending member 314 is provided with a second connecting portion 311 and a pressing portion 3141 at both its left and right ends. The first conductive member 315 is positioned near the second connecting portion 311 at its left end, and the second conductive member 316 is positioned near the second connecting portion 311 at its right end. When the pressing portions 3141 at both ends are simultaneously subjected to an action towards the interior of the mounting cavity 3131... By applying force, the second connecting part 311 on the left end moves to the right toward the mounting cavity 3131, and the second connecting part 311 on the right end moves to the left toward the mounting cavity 3131, so that the second connecting part 311 on the left end comes into contact with the first conductive element 315, and the second connecting part 311 on the right end comes into contact with the second conductive element 316, thereby causing the two second connecting parts 311 to separate from their respective first connecting parts 211, and then the connector plug 310 can be smoothly pulled out from the cable interface 210.
[0058] Both the first conductive element 315 and the second conductive element 316 can be in the form of conductive pins or conductive posts. The socket assembly 230 may include a first socket corresponding to the first conductive element 315 and a second socket corresponding to the second conductive element 316.
[0059] It should be noted that "a certain body" or "a certain part" can be a portion of the corresponding "component," meaning that "a certain body" or "a certain part" is integrally formed and manufactured with the "other parts of the component"; or it can be an independent component that can be separated from the "other parts of the component," meaning that "a certain body" or "a certain part" can be manufactured independently and then combined with the "other parts of the component" to form a whole. The expression of "a certain body" or "a certain part" in this application is only one embodiment for ease of reading, and is not intended to limit the scope of protection of this application.

In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0063] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
