Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a sliding buckle structure and an adjusting device. Background Art

[0002] Steep pulse surgery delivers low-energy electrical pulses to cells, causing cell membrane penetration and imbalance, thereby leading to cell apoptosis. Steep pulse therapy instruments deliver high-voltage low-energy direct current (LEDC) to ablate soft tissue. This ablation method is called electroporation or irreversible electroporation (IRE). The electrode probe is one of the keys to steep pulse surgery. The exposed surface of the electrode probe can produce echoes, which can improve visibility under ultrasound, while the exposure depth of the electrode probe determines the height or depth of ablation. When the soft tissue of the tumor lesion is large, steep pulse surgery requires the use of two or more single electrode probes to achieve the effect of ablating soft tissue. However, since traditional probes are difficult to adjust and the effect cannot be controlled more accurately, the operation time will be increased and the surgical risk will be increased.

[0034] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0035] like Figure 1 and Figure 2As shown, an embodiment discloses a sliding buckle structure, including an adjusting member 100 and at least two sliding members 200, one end of the sliding member 200 is provided with a sliding groove 201, and different sliding members 200 are arranged in sequence along the extension direction of the sliding groove 201, the other end of the previous sliding member 200 is slidably matched with the sliding groove 201 of the subsequent sliding member 200, and the other end of the previous sliding member 200 is limited in the sliding groove 201 of the subsequent sliding member 200, the adjusting member 100 is slidably matched with the sliding groove 201 of the frontmost sliding member 200, and the adjusting member 100 is limited in the sliding groove 201 of the frontmost sliding member 200.

[0036] In the above-mentioned sliding buckle structure, since the adjusting member 100 is limited in the sliding groove 201 of the frontmost sliding member 200, and the end of the front sliding member 200 away from the sliding groove 201 is limited in the sliding groove 201 of the rear sliding member 200, when the rear sliding member 200 is moved, the adjusting member 100 and the front sliding member 200 are driven to move together, and the relative position between the adjusting member 100 and the sliding member 200 and between two adjacent sliding members 200 can be adjusted at the same time, so the sliding members 200 can be moved in sequence according to a certain order. 0 or adjusting member 100, to achieve orderly adjustment of the relative positions of the sliding member 200 and the adjusting member 100, the adjustment is simpler, and at the same time, after the latter sliding member 200 slides, the adjusting member 100 or the former sliding member 200 can further adjust its position after moving a certain distance with the latter sliding member 200, so that precise adjustment can be achieved. If the sliding member 200 and the adjusting member 100 are respectively connected to different components, the relative positions of different components can be orderly adjusted, the adjustment is simple and precise, and the work efficiency can be improved.

[0037] In one embodiment, if Figures 2 to 4As shown, a first limit block 202 which can move up and down is provided on one end of the sliding member 200 away from the sliding groove 201, a first clearance groove 203 and at least two first limit openings 204 are provided on the side wall of the sliding groove 201, the first limit opening 204 matches the first limit block 202, the first clearance groove 203 can slide with the first limit block 202, the first clearance groove 203 is arranged along the extension direction of the sliding groove 201, the first limit openings 204 are arranged in sequence along the extension direction of the sliding groove 201, and the first limit openings 204 are arranged above the first clearance groove 203 and are connected to the first clearance groove 203. When the first limit block 202 enters the first limit opening 204, the first limit block 202 is limited in the slide groove 201. When the first limit block 202 enters the first give way groove 203, the first limit block 202 can slide along the first give way groove 203. At this time, the relative position between the two adjacent sliding members 200 can be adjusted. At the same time, when the first limit block 202 is in the first limit opening 204, the movement of the rear sliding member 200 will drive the movement of the front sliding member 200 to realize the overall movement of the sliding member 200. Then, the first limit block 202 can be adjusted again to adjust the distance between the front sliding member 200 and the rear sliding member 200, so that the adjustment is more precise.

[0038] Optionally, in two adjacent sliding members 200 , the distance between two adjacent first limit openings 204 in one sliding member 200 is L1, and the distance between two adjacent first limit openings 204 in the other sliding member 200 is L2, then L1=L2. This facilitates calculation of the distance moved along the slide slot 201.

[0039] Optionally, the number of the first limiting openings 204 and the length of the first clearance grooves 203 in different sliding grooves 201 may be different.

[0040] Optionally, both side walls of the slide groove 201 are provided with a first clearance groove 203 and at least two first limiting openings 204, and both sides of the sliding member 200 are provided with a first limiting block 202. In this case, the sliding member 200 is more stable when sliding along the slide groove 201, and the sliding member 200 is more stable when positioned and will not move easily.

[0041] In one embodiment, if Figures 2 to 4As shown, the sliding member 200 includes a main body 210, a pressing portion 211 is provided on the main body 210, the pressing portion 211 and the slide groove 201 are respectively provided at two ends of the main body 210, a pressing opening 212 is provided between the main body 210 and the pressing portion 211, and the first stopper 202 is connected to the pressing portion 211. At this time, since there is a pressing opening 212 between the pressing portion 211 and the main body 210, the pressing portion 211 can be pressed to deform the pressing portion 211, thereby causing the first stopper 202 connected to the pressing portion 211 to move in the up-down direction, so that the first stopper 202 enters the first stopper opening 204 or enters the first clearance groove 203.

[0042] In other embodiments, a spring, rubber, etc. may be provided between the pressing portion 211 and the main body 210. The pressing portion 211 may also move in the up-down direction when pressed.

[0043] In one embodiment, if Figure 2 , Figure 5 and Figure 6 As shown, the above-mentioned sliding buckle structure also includes a handle 300, on which a matching groove 310 is provided, and the adjusting member 100 and the sliding member 200 are both slidably matched with the matching groove 310, and a second giving way groove 320 and at least two second limiting openings 330 are provided in the matching groove 310, and the second limiting openings 330 match the first limiting block 202, and the second giving way groove 320 can be slidably matched with the first limiting block 202, and the second giving way groove 320 is arranged along the extension direction of the matching groove 310, and the second limiting openings 330 are arranged in sequence along the extension direction of the matching groove 310, and the second limiting openings 330 are arranged above the second giving way groove 320 and communicate with the second giving way groove 320. At this time, the sliding member 200 located at the rear can also adjust the moving distance of the sliding member 200 by matching with different second limiting openings 330, and the handle 300 is convenient to hold during adjustment.

At this time, the moving distance of the sliding member 200 can be conveniently adjusted by observing the plane.

[0045] In one embodiment, if Figure 6As shown, a accommodating cavity 350 is provided in the handle 300, and the matching groove 310 is connected to the accommodating cavity 350. The main body 210 includes a connecting portion 213 and an external portion 214 connected to each other. The connecting portion 213 is slidably matched with the matching groove 310. The external portion 214 is arranged outside the handle 300, and the sliding groove 201 is arranged at one end of the external portion 214. An opening on one side of the first limiting opening 204 is located on the outer surface of the external portion 214, and the pressing portion 211 is connected to the other end of the external portion 214. Since the structure inside the slide groove 201 is relatively complex, the size of the portion where the slide groove 201 is located will be larger. The portion where the slide groove 201 is located is located in the matching groove 310 or in the accommodating cavity 350, which will affect the overall size of the handle 300 and is inconvenient to move the first limit block 202 and enter different first limit openings 204. Therefore, the slide groove 201 and the downward pressing portion 211 are both arranged on the external portion 214, so that the structure of the handle 300 is more compact, and it is convenient to adjust the position of the sliding member 200 and the adjusting member 100.

[0046] Optionally, the external part 214 includes a front end, a middle end and a rear end, the chute 201 is arranged on the front end, the pressing part 211 is arranged on the rear end, the connecting part 213 is connected to the middle end, wherein the thickness of the middle end and the rear end is equal to the width of the chute 201, the front end is a rectangular block, and the corners of the front end are all rounded. In this case, the setting of the external part 214 is reasonable and convenient to operate.

[0047] In one embodiment, if Figure 1 and Figure 3 As shown, a through hole 215 is provided on the end surface of the external part 214 away from the pressing hole 212, and one end of the slide groove 201 is connected to the through hole 215. At this time, the adjusting member 100 and the sliding member 200 can be assembled in sequence along a straight line, and the assembled structure is more compact, which is conducive to reducing the overall size of the above-mentioned sliding buckle structure.

[0048] Alternatively, if Figure 3 As shown, the pressing portion 211 is further provided with a button 216, which is arranged outside the handle 300. By pressing the button 216, the pressing portion 211 can be pressed conveniently.

[0049] In one embodiment, if Figure 2 As shown, the adjusting member 100 is provided with a second stopper 110 movable in the up-down direction, the second stopper 110 matches the first stopper opening 204, and the second stopper 110 can slide with the first clearance groove 203. At this time, the adjusting member 100 can also adjust its position in the slide groove 201 accordingly.

[0050] Optionally, the structure of the adjusting member 100 is similar to the end of the sliding member 200 away from the sliding groove 201. That is, the second limiting block 110 can also move up and down by squeezing the adjusting member 100.

[0051] In one embodiment, if Figures 7 to 9 As shown, a first elastic member 205 is provided on one end of the sliding member 200 away from the sliding groove 201, and at least two third limiting openings 206 are provided on the side wall of the sliding groove 201. The first elastic member 205 has a normal state and a bent state. When the first elastic member 205 is in the normal state, the end of the first elastic member 205 is stuck in the third limiting opening 206. When the first elastic member 205 is in the bent state, the end of the first elastic member 205 is disengaged from the third limiting opening 206 and is located in the sliding groove 201. Under normal conditions, the end of the first elastic member 205 is stuck in the third limit opening 206. At this time, the position of the sliding member 200 is limited. The first elastic member 205 is bent so that the first elastic member 205 enters a bent state. At this time, the end of the first elastic member 205 can be disengaged from the third limit opening 206 and located in the slide groove 201. The first elastic member 205 can move along the slide groove 201. Then, the first elastic member 205 is restored to a normal state. The end of the first elastic member 205 re-enters the third limit opening 206, thereby realizing the orderly movement of the sliding member 200 in the slide groove 201.

[0052] Alternatively, if Figures 7 to 9 As shown, a first top block 207 matching the third limit opening 206 is provided on one end of the first elastic member 205 away from the sliding member 200, and in a normal state, the first top block 207 is located in the third limit opening 206. Specifically, a pressing block is further provided on one end of the first elastic member 205 away from the sliding member 200. The first elastic member 205 can be bent by squeezing the pressing block.

[0053] Alternatively, if Figures 7 to 9 As shown, the third limiting openings 206 are provided on both opposite side walls of the slide groove 201. Figure 7 and Fig. 9 As shown, a V-shaped opening is provided at one end of the sliding member 200, and both sides of the V-shaped opening are the first elastic member 205. At this time, by bending the first elastic member 205 into the V-shaped opening, the first elastic member 205 is in a first bending state, so that the first top block 207 can be separated from the limiting opening and slide in the sliding groove 201. After the first elastic member 205 is released, the first elastic member 205 returns to a normal state, and the first top block 207 is re-engaged in the limiting opening.

[0054] Alternatively, if Figures 7 to 9 As shown, the adjusting member 100 is provided with a second elastic member 130, and the second elastic member 130 can be bent so that the second elastic member 130 enters or leaves the third limiting opening 206. At this time, the adjusting member 100 can also adjust its position in the sliding groove 201.

[0055] Specifically, Figures 7 to 9 As shown, the second elastic member 130 has the same structure as the first elastic member 205 .

At this time, the sliding member 200 can also be moved along the handle 300 by squeezing the first elastic member 205. Specifically, the adjustable slot 360 is located in the extension direction of the matching slot 310.

[0058] like Figures 10 to 12 As shown, an embodiment discloses an adjustment device, including a dual-electrode probe and a sliding buckle structure as described above, wherein there are two sliding members 200, the two sliding members 200 are respectively a first sliding member 220 and a second sliding member 230, the sliding groove 201 on the first sliding member 220 is slidably matched with the adjustment member 100, the dual-electrode probe includes a first electrode 410, a first insulating sleeve 420, a second electrode 430 and a second insulating sleeve 440 which are sequentially sleeved from the inside to the outside, the second insulating sleeve 440 is connected to the adjustment member 100, the second electrode 430 is connected to the first sliding member 220, and the first insulating sleeve 420 is connected to the second sliding member 230.

[0059] In the above-mentioned adjusting device, when the second sliding member 230 moves, it can drive the first sliding member 220 and the adjusting member 100 to move, that is, when the first insulating sleeve 420 moves, it will drive the second electrode 430 and the second insulating sleeve 440 to move together, and at the same time, the first insulating sleeve 420, the second electrode 430 and the second insulating sleeve 440 move as a whole relative to the first electrode 410, so that one end of the first electrode 410 extends out of the first insulating sleeve 420, and the length of the first electrode 410 extending out is controlled by the moving distance of the second sliding member 230, and then the first sliding member 220 is moved, that is, when the second electrode 430 moves, it drives the second insulating sleeve 440 to move together, and at the same time, the second electrode 430 and the second insulating sleeve 440 move as a whole relative to the first insulating sleeve 420, and then the adjusting member 100 is moved. The joint part 100 enables the second insulating sleeve 440 to move relative to the second electrode 430, and controls the extended length of the second electrode 430 by the moving distance of the adjusting part 100. Therefore, the above-mentioned adjusting device can adjust the extended length of the first electrode 410 and the second electrode 430, that is, the exposure depth of the first electrode 410 and the second electrode 430 can be controlled according to the situation.

In the initial state, the end of the first electrode 410 away from the first sliding member 220 is located in the first insulating sleeve 420, that is, the rear end of the first insulating sleeve 420 extends through the first electrode 410, and the rear end of the second insulating sleeve 440 extends through the rear end of the second electrode 430. In the use state, the end of the first electrode 410 away from the first sliding member 220, the rear end of the first insulating sleeve 420, the rear end of the second electrode 430 and the rear end of the second insulating sleeve 440 are extended out in sequence. In the initial state, since the first insulating sleeve 420 extends over the first electrode 410 and the second insulating sleeve 440 extends over the second electrode 430, the first electrode 410 and the second electrode 430 can be protected. In the use state, the first electrode 410 and the second electrode 430 are both exposed, and a passage can be formed at the insertion position after insertion.

[0061] Optionally, the length of the end of the first electrode 410 away from the first sliding member 220 extending out of the first insulating sleeve 420 is equal to the length of the front end of the second electrode 430 extending out of the second insulating sleeve 440. In this case, the exposure depths of the first electrode 410 and the second electrode 430 are equal, so when a path is formed between the first electrode 410 and the second electrode 430, the current intensity is relatively stable and the effect of use is better.

[0062] Optionally, one end of the first electrode 410 away from the first sliding member 220 is a pointed end, so as to facilitate the insertion of the first electrode 410 .

[0063] Optionally, the slide groove 201 is arranged along the axial direction of the first electrode 410 .

At this time, the first sleeve portion 120, the second sleeve portion 221 and the third sleeve portion 231 can ensure the stability of movement.

[0065] Optionally, the first sleeve portion 120, the second sleeve portion 221, and the third sleeve portion 231 are all located in the accommodating cavity 350 of the handle 300, and the first sleeve portion 120, the second sleeve portion 221, and the third sleeve portion 231 match the accommodating cavity 350, and the accommodating cavity 350 is a columnar hole arranged along the axial direction of the first electrode 410. At this time, the first sleeve portion 120, the second sleeve portion 221, and the third sleeve portion 231 can stably move in the accommodating cavity 350.

[0066] Alternatively, if Fig.10 and Fig.11As shown, the above-mentioned two-electrode probe further includes a first wiring 510 and a second wiring 520. The first electrode 410 is used to be electrically connected to an external circuit through the first wiring 510, and the second electrode 430 is used to be electrically connected to an external circuit through the second wiring 520. A spring-like structure is provided on both the first wiring 510 and the second wiring 520. Since the relative positions of the first electrode 410 and the second electrode 430 need to be adjusted when adjusting the exposure depth of the first electrode 410 and the second electrode 430, which may drive the first wiring 510 or the second wiring 520 to move accordingly, the spring-like structure is provided on both the first wiring 510 and the second wiring 520 so that the first wiring 510 or the second wiring 520 can be stretched or compressed, and the joint of the first wiring 510 or the second wiring 520 will not be damaged due to movement.

[0067] Optionally, the first connection 510 and the second connection 520 are arranged in parallel. In this case, the overall structure of the electrode probe is relatively compact, and its radial dimension can be reduced, which is more convenient for use.

[0068] Optionally, the handle 300 includes a front nut, a sleeve and a rear nut, the front nut and the rear nut are respectively sleeved on both ends of the sleeve, the front nut, the sleeve and the rear nut form a receiving chamber 350, the end surface of the front nut is provided with a first through hole for the second insulating sleeve 440 to pass through, and the end surface of the rear nut is provided with a second through hole for the first wiring 510 and the second wiring 520 to pass through. At this time, the components in the sleeve can be replaced or repaired by removing the front nut and the rear nut.

[0069] Alternatively, if Fig.10 As shown, the dual-electrode probe further includes a sliding tube 600, which includes a first connection portion 610 sleeved outside the second connection 520 and a second connection portion 620 sleeved outside the second electrode 430, the first connection portion 610 is connected to the second connection portion 620, and the inner hole of the first connection portion 610 is communicated with the inner hole of the second connection portion 620. Since the second electrode 430 is sleeved outside the first electrode 410, the electrical connection between the second electrode 430 and the second connection 520 will be pulled when the second electrode 430 moves, so the sliding tube 600 can be used to protect the connection between the second electrode 430 and the second connection 520.

[0070] Specifically, the first connecting portion 610 is an L-shaped tube, which facilitates the electrical connection between the second connecting wire 520 and the second electrode 430 .

[0071] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
