Description

Technical Field

[0001] This invention relates to the field of medical device manufacturing technology, and in particular to a flexible conductive body fixing mechanism. Background Technology

[0002] Treatment catheters typically incorporate energy-generating components to produce energy. These components can take various forms, including piezoelectric crystals, radio frequency electrodes, and microwave generators. For example, a piezoelectric crystal converts electrical energy into ultrasonic energy. The energy-generating component also includes a flexible conductor (e.g., sheet-like metals such as copper or silver) to connect the piezoelectric crystal. Generally, the insulating coating of the flexible conductor is partially removed using laser ablation, the piezoelectric crystal is then assembled to the laser-ablated area, and finally fixed using methods such as adhesive application or welding.

[0003] However, due to the fine dimensions of flexible conductors and piezoelectric crystals, existing technologies are prone to skewing, warping, and bending during the fixation process of flexible conductors, making it difficult to achieve precise fixation and affecting the accuracy of subsequent flexible conductor processing (such as laser peeling, welding, etc.).

[0004] In view of this, it is necessary to improve the existing mechanisms for fixing flexible conductors in order to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to disclose a flexible conductor fixing mechanism to solve many defects in existing mechanisms for fixing flexible conductors, especially to achieve precise fixing of flexible conductors and avoid phenomena such as skewing, warping and bending that occur during the fixing process.

[0006] To achieve the above objectives, the present invention provides a flexible conductor fixing mechanism, comprising: a base plate, a support mechanism disposed on the base plate, and a clamping mechanism disposed laterally on both sides of the support mechanism, wherein the clamping mechanism clamps both ends of the flexible conductor laterally.

[0007] The flexible conductor includes: a first conductive segment and a plurality of second conductive segments formed on the first conductive segment;

[0008] The support mechanism includes: a support block, wherein the support block forms a groove in the transverse direction that at least partially accommodates the flexible conductor;

[0009] The groove includes: a plurality of positioning grooves that at least partially accommodate the second conductive segment, and a limiting groove that connects to the positioning grooves and at least partially accommodates the first conductive segment.

[0010] As a further improvement of the present invention, the supporting block is configured as a first abutment block and a second abutment block arranged longitudinally opposite each other;

[0011] The groove is configured as a first receiving groove and a second receiving groove formed by the sides of the first abutment and the second abutment that are close to each other.

[0012] As a further improvement of the present invention, the first abutment and the second abutment abut against each other longitudinally, the first receiving groove and the second receiving groove cooperate to form a plurality of positioning grooves that at least partially accommodate the second conductive segment, and a limiting groove that connects to the positioning grooves and at least partially accommodates the first conductive segment.

[0013] As a further improvement of the present invention, the supporting mechanism further includes:

[0014] A connecting block is vertically disposed between the support block and the base plate, wherein the connecting block protrudes vertically from several sets of first protrusions and second protrusions arranged longitudinally opposite each other;

[0015] The first abutment and the second abutment are respectively separated by the first protrusion and the second protrusion to form multiple sets of first support blocks and second support blocks.

[0016] As a further improvement of the present invention, the tank includes:

[0017] A first retaining groove is formed on the side where the first protrusion and the second protrusion are close to each other to accommodate the first conductive segment;

[0018] A second holding groove is formed on the side of the first support block and the second support block that are close to each other, which accommodates the second conductive segment.

[0019] As a further improvement of the present invention, the tank includes:

[0020] A first retaining groove is formed on the side where the first protrusion and the second protrusion are close to each other to accommodate the second conductive segment;

[0021] A second holding groove is formed on the side of the first support block and the second support block that are close to each other, which accommodates the first conductive segment.

[0022] As a further improvement of the present invention, the tank includes:

[0023] The portion formed on the side where the first protrusion and the second protrusion are close to each other accommodates the first retaining groove of the first conductive segment and the second conductive segment;

[0024] The portion formed on the side where the first support block and the second support block are close to each other accommodates the second retaining groove of the first conductive segment and the second conductive segment.

[0025] As a further improvement of the present invention, the clamping mechanism includes:

[0026] Two sets of guide blocks are arranged laterally at both ends of the support block, and two sets of clamping blocks are arranged longitudinally symmetrically on both sides of the guide block.

[0027] As a further improvement of the present invention, the guide block forms at least one guide groove along the longitudinal direction, and the clamping block is configured to move longitudinally along the guide groove to clamp the clamping end of the flexible conductor.

[0028] As a further improvement of the present invention, the guide block is separated by the guide groove on the side near the support block to form a receiving block, and the receiving block is configured to communicate with the limiting groove and at least partially accommodate the end of the flexible conductor.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] The flexible conductor is placed within the groove of the support block, with a positioning groove accommodating the second conductive segment and a limiting groove accommodating the first conductive segment. This prevents the flexible conductor from tilting, warping, or bending within the groove, thus pre-fixing the first and second conductive segments and preventing the flexible conductor from loosening during clamping. The clamping mechanism then holds both ends of the flexible conductor laterally to further secure it, preventing it from loosening and detaching from the groove during processing (e.g., laser peeling, assembly with piezoelectric crystals), ensuring the precision of the flexible conductor processing.

[0046] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent changes or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0047] In particular, it should be noted that in the following embodiments, the term "flexible conductor" refers to a conductive material that can be deformed, and there is no limitation on the degree of deformation. As long as the conductive material that can be deformed, it can be the same as or equivalent to the "flexible conductor" of the present application.

[0048] The term "longitudinal direction" refers to Figure 1 the direction shown by the coordinate axis Y in Figure 1 The term "lateral direction" refers to Figure 1 the direction shown by the coordinate axis X in

[0049] Please refer to Figures 1 to 15 a specific implementation manner of a flexible conductor fixing mechanism disclosed.

[0050] The flexible conductor fixing mechanism disclosed in this embodiment is used to accurately fix the flexible conductor 100, and can avoid phenomena such as skew, warping, and bending that occur during the process of fixing the flexible conductor 100 in the prior art, so as to ensure the accuracy of the flexible conductor 100 in subsequent processes such as laser peeling and assembly with a piezoelectric crystal (not shown).

[0051] Refer to Figures 1 to 15 As shown, in this embodiment, the flexible conductor fixing mechanism includes: a bottom plate 10, a supporting mechanism 20 disposed on the bottom plate 10, and clamping mechanisms 30 arranged along the lateral direction on both sides of the supporting mechanism 20. The clamping mechanisms 30 clamp both ends of the flexible conductor 100 along the lateral direction; the flexible conductor 100 includes: a first conductive segment 101 and a plurality of second conductive segments 102 formed on the first conductive segment 101; the supporting mechanism 20 includes: a supporting block 21, and the supporting block 21 forms a groove body 22 that at least partially accommodates the flexible conductor 100 along the lateral direction; the groove body 22 includes: a plurality of positioning grooves 222 that at least partially accommodate the second conductive segments 102, and a limiting groove 221 that communicates with the positioning grooves 222 and at least partially accommodates the first conductive segment 101.

[0052] When fixing the flexible conductor 100, the flexible conductor 100 is first placed in the groove 22 of the support block 21, and the second conductive segment 102 is accommodated by the positioning groove 222, and the first conductive segment 101 is accommodated by the limiting groove 221. Preferably, the shapes of the positioning groove 222 and the limiting groove 221 are adapted to the contours of the second conductive segment 102 and the first conductive segment 101, respectively, so that the first conductive segment 101 and the second conductive segment 102 can be respectively held and fitted in the limiting groove 221 and the positioning groove 222, thereby avoiding the flexible conductor 100 from tilting, warping, or bending in the groove 22. This pre-fixes the first conductive segment 101 and the second conductive segment 102 through the limiting groove 221 and the positioning groove 222, and prevents the flexible conductor 100 from loosening when clamped by the clamping mechanism 30. Then, the clamping mechanism 30 moves along... Figure 1 The flexible conductor 100 is clamped at both ends in the direction shown by the X-axis to fix the flexible conductor 100, thereby preventing the flexible conductor 100 from loosening and detaching from the groove 22 during the processing (e.g., laser peeling, assembly with piezoelectric crystal, etc.), so as to ensure the processing accuracy of the flexible conductor 100.

[0053] It should be noted that the number of positioning grooves 222 can be set according to actual needs. The number of positioning grooves 222 can be the same as or greater than the number of second conductive segments 102. In this embodiment, the number of positioning grooves 222 is preferably the same as the number of second conductive segments 102. Because the second conductive segments 102... Figure 1 The width along the Y-axis is greater than that along the first conductive segment 101. Figure 1 The width in the direction shown by the Y-axis is such that an external laser device (not shown) can laser-strip the second conductive segment 102 contained in the fixed flexible conductor 100 and assemble the piezoelectric crystal (not shown) to the second conductive segment 102.

[0054] It should be noted that the positioning groove 222 is along Figure 1 The depth in the direction indicated by the Z-axis can be configured to be less than the thickness of the second conductive segment 102, thereby enabling the positioning groove 222 to partially accommodate the second conductive segment 102. Alternatively, the positioning groove 222 can be configured to extend along... Figure 1 The depth along the Z-axis is equal to the thickness of the second conductive segment 102, thus enabling the positioning groove 222 to completely accommodate the second conductive segment 102. Any depth sufficient to accommodate the second conductive segment 102 is acceptable; however, in this embodiment, the positioning groove 222 is preferably along... Figure 1 The depth along the Z-axis is less than the thickness of the second conductive segment 102. Meanwhile, the limiting groove 221 extends along... Figure 1The depth in the direction indicated by the Z-axis is preferably less than the thickness of the first conductive segment 101. The depth of the positioning groove 222 and the depth of the limiting groove 221 can be set according to the thickness of the first conductive segment 101 and the second conductive segment 102. As long as the positioning groove 222 and the limiting groove 221 can keep the first conductive segment 101 and the second conductive segment 102 in a horizontal position when accommodating them, it can prevent the flexible conductor 100 from warping or bending.

[0055] For example, such as Figures 4 to 7 As shown, the supporting block 21 is configured as a first abutment 211 and a second abutment 212 arranged longitudinally opposite each other; the groove 22 is configured as a first receiving groove 223 and a second receiving groove 224 formed respectively on the side of the first abutment 211 and the second abutment 212 that are close to each other. The first abutment 211 and the second abutment 212 abut against each other longitudinally, and the first receiving groove 223 and the second receiving groove 224 cooperate to form a plurality of positioning grooves 222' that at least partially accommodate the second conductive segment 102, and a limiting groove 221' that connects to the positioning grooves 222' and at least partially accommodates the first conductive segment 101. By longitudinally abutting the first abutment 211 and the second abutment 212, the first receiving groove 223 and the second receiving groove 224 are spliced ​​together to form a groove 22. The groove 22 formed by this splicing also includes several positioning grooves 222' that at least partially accommodate the second conductive segment 102, and a limiting groove 221' that connects to the positioning grooves 222' and at least partially accommodates the first conductive segment 101. In use, the flexible conductor 100 can be placed in the first receiving groove 223 or the second receiving groove 224 first, and then the first abutment 211 and the second abutment 212 can be driven to move towards each other along the Y-axis by an external driving device (not shown) to longitudinally abut and fix the flexible conductor 100 through the first receiving groove 223 and the second receiving groove 224, thereby preventing the flexible conductor 100 from tilting, warping, or bending during the fixing process.

[0056] It should be noted that the support block 21 is preferably made of aluminum, which has lower precision requirements than metals such as stainless steel and can reduce production costs. In this embodiment, the support block 21 is preferably a split type, which includes a first abutment 211 and a second abutment 212 arranged longitudinally opposite each other to facilitate manufacturing.

[0057] For example, such as Figures 9 to 15As shown, the supporting mechanism 20 further includes: a connecting block 23 disposed vertically between the supporting block 21 and the base plate 10, the connecting block 23 having several sets of first protrusions 231 and second protrusions 232 disposed longitudinally opposite each other in the vertical direction; the first abutment 211 and the second abutment 212 are respectively separated by the first protrusions 231 and the second protrusions 232 to form multiple sets of first support blocks 2111 and second support blocks 2121, the first protrusions 231 and the first support blocks 2111 are arranged alternately, and the second protrusions 232 and the second support blocks 2121 are arranged alternately. When installing the first abutment 211 and the second abutment 212, the gap between the first protrusion 231 and the second protrusion 232 can guide and position the first support block 2111 and the second support block 2121, so that the first support block 2111 and the second support block 2121 can be inserted longitudinally along the gap between the first protrusion 231 and the second protrusion 232 until the first support block 2111 and the second support block 2121 abut against each other longitudinally. This improves the accuracy of the installation of the first support block 2111 and the second support block 2121 on the connecting block 23 and avoids the first support block 2111 and the second support block 2121 from shifting, which would cause the second holding groove 2112 to deform and make it difficult to accommodate the second conductive segment 102.

[0058] Specifically, the groove 22 includes: a first holding groove 233 formed on the side where the first protrusion 231 and the second protrusion 232 are close to each other to accommodate the first conductive segment 101; and a second holding groove 2112 formed on the side where the first support block 2111 and the second support block 2121 are close to each other to accommodate the second conductive segment 102. The first holding groove 233 and the second holding groove 2112 respectively accommodate the first conductive segment 101 and the second conductive segment 102. The shapes of the first holding groove 233 and the second holding groove 2112 are respectively adapted to the contours of the second conductive segment 102 and the first conductive segment 101, so that the first conductive segment 101 and the second conductive segment 102 can be respectively held and attached to the limiting groove 221 and the positioning groove 222, thereby avoiding the flexible conductor 100 from being tilted, raised, or bent in the groove 22.

[0059] For example, such as Figure 14As shown, the groove 22 includes: a first retaining groove 233' formed on the side where the first protrusion 231 and the second protrusion 232 are close to each other to accommodate the second conductive segment 102; and a second retaining groove 2112' formed on the side where the first support block 2111 and the second support block 2121 are close to each other to accommodate the first conductive segment 101. The first retaining groove 233' and the second retaining groove 2112' can also accommodate the first conductive segment 101 and the second conductive segment 102 respectively. The shapes of the first retaining groove 233' and the second retaining groove 2112' are respectively adapted to the contours of the second conductive segment 102 and the first conductive segment 101, so that the first conductive segment 101 and the second conductive segment 102 can be respectively retained and attached to the limiting groove 221 and the positioning groove 222, thereby avoiding the flexible conductor 100 from being tilted, raised, or bent in the groove 22.

[0060] For example, such as Figure 15 As shown, the groove 22 includes: a first retaining groove 233” formed on the side where the first protrusion 231 and the second protrusion 232 are close to each other to accommodate the first conductive segment 101 and the second conductive segment 102; and a second retaining groove 2112” formed on the side where the first support block 2111 and the second support block 2121 are close to each other to accommodate the first conductive segment 101 and the second conductive segment 102. Alternatively, the first conductive segment 101 and the second conductive segment 102 can be partially accommodated by the first retaining groove 233” and the second retaining groove 2112”. The shapes of the first retaining groove 233” and the second retaining groove 2112” are respectively adapted to the contours of the second conductive segment 102 and the first conductive segment 101, so that the first conductive segment 101 and the second conductive segment 102 can be respectively retained and attached to the limiting groove 221 and the positioning groove 222, thereby avoiding the flexible conductor 100 from being tilted, raised, or bent in the groove 22.

[0061] For example, a vacuum channel (not shown) connecting the groove 22 can be formed in the support block 21 and / or connecting block 23, and an external vacuum extraction device (not shown) can be connected to the vacuum channel. The external vacuum extraction device extracts air from the vacuum channel and forms a negative pressure to adsorb and fix the flexible conductor 100. At this time, without clamping both ends of the flexible conductor 100 by the clamping mechanism 30, the negative pressure adsorption and fixation of the flexible conductor 100 can also prevent loosening and detachment from the groove 22, thus ensuring the processing accuracy of the flexible conductor 100.

[0062] like Figures 1 to 6 and Figure 10As shown, the clamping mechanism 30 includes two sets of guide blocks 31 arranged laterally at both ends of the support block 21, and two sets of clamping blocks 32 symmetrically arranged longitudinally on both sides of the guide blocks 31. The clamping blocks 32 are driven to move longitudinally by an external driving device (not shown) to clamp and fix the two ends of the laterally placed flexible conductor 100, preventing the flexible conductor 100 from loosening during processing and avoiding the flexible conductor 100 from detaching from the groove 22.

[0063] Specifically, the guide block 31 is separated by a guide groove 311 on the side near the support block 21 to form a receiving block 312. The receiving block 312 is configured to have a guide groove 313 that connects to the limiting groove 221 and at least partially accommodates the ends of the flexible conductor 100. The two ends of the flexible conductor 100 are accommodated through the guide groove 313. The guide block 31 forms at least one guide groove 311 in the longitudinal direction, and the clamping block 32 is configured to move longitudinally along the guide groove 311 to clamp the ends of the flexible conductor 100. The clamping end 321 moves longitudinally along the guide groove 311 to clamp and fix the ends of the flexible conductor 100 that extend through the guide groove 313, so as to prevent the flexible conductor 100 from loosening and detaching from the groove 22 during processing (e.g., laser peeling, assembly with piezoelectric crystals, etc.), and to ensure the accuracy of the processing of the flexible conductor 100.
