Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a shockwave operating handle. Background Technology

[0002] Shockwave handpieces are commonly used in intravascular shockwave systems. They are operating control devices used by shockwave systems to emit high-voltage pulses to break up target substances, which are usually considered to be calcifications. Operating the shockwave handpiece can cause the intravascular shockwave system to release instantaneous high voltage to break up calcifications in the blood vessels to achieve therapeutic purposes.

[0003] An existing shockwave handle has the following drawbacks: it lacks a waterproof seal design, posing a risk of water ingress during use and affecting signal transmission.

[0004] Therefore, how to improve the waterproof performance of the shockwave handle is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a shockwave operating handle with good waterproof effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A shockwave operating handle includes a handle end and a plug end; a first sealing ring is provided on the handle end and / or the plug end, and after the handle end and the plug end are electrically connected, the first sealing ring forms a seal between the handle end and the plug end.

[0008] For example, both the plug end and the handle end are provided with connectors that are plugged in and electrically connected.

[0009] For example, the connector on the plug end is a male connector protruding from the first plug end face of the plug end, and the first sealing ring is sleeved on the outside of the male connector. The connector on the handle end is a female connector built into the first handle end face of the handle end, and the first sealing ring abuts between the first plug end face and the first handle end face.

[0010] For example, the connector at the plug end and the connector at the handle end are also magnetically connected.

[0011] For example, the connector includes a magnetic element and a plurality of electrical connectors. The connectors on the plug end and the connectors on the handle end are magnetically connected by the corresponding magnetic elements and electrically connected by the insertion and engagement of the corresponding electrical connectors. On the connector, all the electrical connectors are arranged sequentially around the magnetic element.

[0012] For example, in the connector, some of the electrical connectors are arranged sequentially along a straight line, and the remaining electrical connectors are arranged sequentially along an arc.

[0013] For example, a guide groove is provided on one of the connectors on the plug end and the connectors on the handle end, and an inner magnetic attracting member is provided in the guide groove. An outer magnetic attracting member protrudes from the other end and extends into the guide groove and is magnetically connected to the inner magnetic attracting member.

[0014] For example, the handle end includes a handle housing, the handle housing includes a first half-shell and a second half-shell that are engaged, and a housing seal is provided at the engagement point.

[0015] For example, the snap-fit ​​joints of the first half-shell and the second half-shell are provided with matching stepped surfaces.

[0016] For example, the handle end includes a handle housing, a trigger, and a handle electronic control; the handle electronic control is built into the handle housing, the trigger is disposed on the mounting hole of the handle housing, and the trigger is activated by movement to activate the handle electronic control; the trigger is sealed to the mounting hole.

[0017] For example, the trigger includes a button assembly, which includes a button cap and a trigger rod. The button cap is waterproof and has a button sealing ring between the button cap and the mounting hole. The button cap wraps around one end of the trigger rod away from the handle housing and covers the mounting hole. The other end of the trigger rod extends into the interior of the handle housing. The button cap triggers the handle electronic control by driving the trigger rod to slide into the handle housing.

[0018] For example, the button sealing ring is integrally formed on the outer surface of the button cap.

[0019] For example, a locking nut is also provided inside the handle housing; the button assembly also includes a button seat connected to the button cap, the button seat being threadedly connected to the locking nut, and the trigger rod being slidably inserted into the button seat.

[0020] For example, the handle end includes a handle housing, a handle control, and a bushing assembly. The bushing assembly is connected to the handle housing, the handle control is built into the handle housing, and the cable of the handle control extends through the bushing assembly. The bushing assembly includes a main sleeve structure, which includes a rigid skeleton and a soft layer covering the rigid skeleton. The cable is interference-fitted with the soft layer.

[0021] For example, the handle end includes a handle housing, a handle control, and a bushing assembly. The bushing assembly is connected to the handle housing, the handle control is built into the handle housing, and the cable of the handle control extends through the bushing assembly. The bushing assembly is connected to the handle housing, and a rigid sleeve is provided at one end near the handle housing.

[0022] For example, the handle end includes a handle housing, a handle control, and a bushing assembly. The bushing assembly is connected to the handle housing, the handle control is built into the handle housing, and the cable of the handle control extends through the bushing assembly. A bushing seal is also provided at the connection between the bushing assembly and the handle housing.

[0023] The shockwave operating handle provided by this utility model includes a handle end and a plug end; a first sealing ring is provided on the handle end and / or the plug end, and after the handle end and the plug end are electrically connected, the first sealing ring forms a seal between the handle end and the plug end.

[0024] The plug end of a shockwave operating handle is often disposable, while the handle end is often reusable. This necessitates frequent plugging and unplugging of both ends, inevitably increasing the risk of water ingress. However, the shockwave operating handle structure of this embodiment uses a first sealing ring to seal the connection between the handle end and the plug end, achieving waterproofing at the connection point. This provides better waterproofing, reduces the risk of water ingress during use, and improves signal transmission performance. Attached Figure Description

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] The core of this invention is to provide a shockwave operating handle with good waterproof performance.

[0044] A specific embodiment of the shockwave operating handle provided by this utility model is a shockwave handle for vascular calcification. Please refer to [reference needed]. Figures 1 to 11 It includes a handle end 2 and a plug end 1. In use, the handle end 2 and the plug end 1 are electrically connected, specifically they can be detachably connected. The plug end 1 is connected to the conduit and discharge electrode of the shock wave system, and the handle end 2 is connected to the generator module of the shock wave system, specifically it can be connected to the main equipment of the shock wave system.

[0045] like Figure 2 As shown, a first sealing ring 12 is provided on the plug end 1. After the handle end 2 is electrically connected to the plug end 1, the first sealing ring 12 forms a seal between the handle end 2 and the plug end 1. Alternatively, in other embodiments, the first sealing ring 12 may also be provided on the handle end 2, or the first sealing ring 12 may be provided on both the plug end 1 and the handle end 2.

[0046] In this shockwave operating handle, a first sealing ring 12 is used to seal the connection between the handle end 2 and the plug end 1, achieving waterproofing at the connection between the handle end 2 and the plug end 1. This provides good waterproofing, reduces the risk of water ingress during use, and improves signal transmission performance.

[0047] Plug end 1 and handle end 2 are electrically connected via a connector assembly, such as Figures 2 to 6 As shown, the connector assembly includes connectors 3 respectively disposed on the plug end 1 and the handle end 2, which are plugged in and electrically connected. It is easy to operate and can be quickly assembled and disassembled. At the same time, the waterproof design can prevent water from entering the connector and ensure the safety of the handle during use.

[0048] Among them, such as Figure 2 and Figure 3 As shown, the connector 3 on the plug end 1 is a male connector 13, and the connector 3 on the handle end 2 is a female connector 211. Wherein, as... Figures 4 to 6 As shown, connector 3 includes connector housing 31 and electrical connector 33 fixed in connector housing 31. Connector housing 31 is specifically a plastic housing, but can also be made of other insulating materials. The electrical connectors 33 of the two connectors 3 are inserted and mated to achieve electrical connection between the two connectors 3. Specifically, the electrical connector 33 of male connector 13 is male pin 132, and the electrical connector 33 of female connector 211 is female pin 2112. Male pin 132 is inserted into and electrically connected to female pin 2112. In addition, female pin 2112 may have a built-in crown spring 2117 to ensure the reliability of electrical connection with male pin 132. Of course, in other embodiments, depending on the actual structural needs, female connector 211 can also be set on plug end 1, and male connector 13 can be set on handle end 2.

[0049] The first sealing ring 12 may be provided in the connector assembly section. For example... Figure 2 and Figure 3 As shown, a male connector 13 protrudes from the first plug end face 111 of the plug end 1, and a first sealing ring 12 is fitted onto the outside of the male connector 13 for easy installation and replacement. A female connector 211 is built into the first handle end face 21 of the handle end 2. The male connector 13 and the female connector 211 are plugged in and electrically connected, thereby realizing the electrical connection between the handle end 2 and the plug end 1. The first sealing ring 12 abuts between the first plug end face 111 and the first handle end face 21, which can effectively prevent water from entering the connector assembly.

[0050] Specifically, such as Figure 2As shown, the plug end 1 includes a plug housing 11, specifically a soft housing. The first plug end face 111 is one end face of the plug housing 11 in the first direction X. The plug end 1 and the handle end 2 are arranged and connected sequentially along the first direction X. The handle end 2 extends along the first direction X, and its two ends are the two ends in the first direction X. Correspondingly, the male connector 13 and the female connector 211 are inserted along the first direction X, and the male pin 132 and the female pin 2112 are inserted along the first direction X.

[0051] Specifically, such as Figure 2 As shown, in order to improve the stability of the installation of the first sealing ring 12, the first sealing ring 12 can be partially embedded in the end face 111 of the first plug, and can also be further bonded and fixed.

[0052] like Figure 4 and Figure 5 As shown, the male connector 13 is provided with a plurality of male pins 132, and the female connector 211 is provided with an equal number of female pins 2112. The male pins 132 and female pins 2112 are inserted one-to-one to improve the reliability of the electrical connection. For example, there may be 11 male pins 132 and 11 female pins 2112. Of course, in other embodiments, there may be 1, 6, etc., as needed.

[0053] To improve connection strength, such as Figures 4 to 5 As shown, the male connector 13 and the female connector 211 are also magnetically connected. Specifically, each connector 3 is provided with a magnetic attracting element 32 for magnetic engagement. For the magnetic attracting elements 32 on the two connectors 3, one can have a magnetic post, and the other can have a non-magnetic iron post that can be attracted by the magnetic post, or a magnetic element with opposite magnetic properties to the magnetic post. For example, the magnetic attracting element 32 on the male connector 13 is the male magnetic attracting element 131, specifically an iron post, and the magnetic attracting element 32 on the female connector 211 is the female magnetic attracting element 2111, specifically a magnetic post. Furthermore, during the connection process, the magnetic force provides an auxiliary effect. As the two connectors 3 approach each other, the magnetic force of the magnetic attracting elements 32 on the connectors 3 continuously increases to achieve rapid connection. When the magnetic attracting elements 32 engage and attract, the corresponding male pin 132 and female pin 2112 complete the electrical signal connection.

[0054] On connector 3, electrical connector 33 and magnetic connector 32 can be glued to the corresponding connector housing 31.

[0055] Regarding the structural design of connector 3, as follows: Figure 4 and Figure 5As shown, all male pins 132 are arranged in sequence around the male magnetic connector 131, and all female pins 2112 are arranged in sequence around the female magnetic connector 2111. At this time, the magnetic connector 32 is centrally located on the corresponding connector 3, and the stability of the connection between the surrounding male pins 132 and female pins 2112 can be improved by means of magnetic connection.

[0056] Based on this, such as Figure 4 and Figure 5 As shown, on the male connector 13, some of the male pins 132 are arranged in a straight line, this part includes multiple male pins 132, and the remaining male pins 132 are arranged in an arc, this part also includes multiple male pins 132. For example, 6 male pins 132 are arranged in a straight line and the remaining 5 male pins 132 are arranged in an arc. Correspondingly, on the female connector 211, some of the female pins 2112 are arranged in a straight line, this part includes multiple female pins 2112, and the remaining female pins 2112 are arranged in an arc, this part also includes multiple female pins 2112. For example, 6 female pins 2112 are arranged in a straight line and the remaining 5 female pins 2112 are arranged in an arc.

[0057] At this time, on each connector 3, the electrical connectors 33 are arranged to form a D-shaped structure around the corresponding magnetic attractor 32, which has a foolproof effect and makes it convenient for operators to judge and adjust the insertion angle between the male connector 13 and the female connector 211, thereby improving insertion efficiency. Adaptively, the connector housing 31 can also be set as a housing with D-shaped sidewalls to match the arrangement direction of the electrical connectors 33, which saves space while allowing the insertion direction to be judged by means of the connector housing 31.

[0058] Based on this, in order to reduce the difficulty of processing, such as Figure 2 and Figure 4 As shown, on the male connector 13, the male pins 132 arranged in a straight line can be considered as a single male pin module, all housed in a first male mounting sleeve 133 on the connector housing 31 of the male connector 13. The remaining male pins 132 arranged in an arc are individually housed in second male mounting sleeves 134 on the connector housing 31 of the male connector 13. Correspondingly, as... Figure 3 and Figure 5As shown, on the female connector 211, each female pin 2112 arranged in a straight line can be considered as a female pin module, all of which are housed in a first female mounting block 2113 on the connector housing 31 of the female connector 211. A second female mounting block 2114 is also provided on the connector housing 31 of the female connector 211. The remaining female pins 2112 arranged in an arc are individually housed in their respective second female mounting slots 2115 on the second female mounting block 2114. During the insertion of the two connectors 3, the first male mounting sleeve 133 is fitted onto the outside of the first female mounting block 2113, and each second male mounting sleeve 134 is correspondingly inserted into its respective second female mounting slot 2115, providing a guiding effect.

[0059] Of course, in other embodiments, all electrical connectors 33 and magnetic connectors 32 on the connector 3 can also be arranged in other ways. For example, multiple magnetic connectors 32 can be provided and arranged on the edge of the connector 3. In addition, each electrical connector 33 can be arranged in a Z-shape.

[0060] To further improve the reliability of the connection, such as Figure 6 As shown, the female connector 211 is also provided with a guide groove 2116, and the female magnetic clasp 2111 is built into the guide groove 2116 as an inner magnetic clasp 32. The guide groove 2116 can be provided on the second female mounting block 2114. The male magnetic clasp 131 on the male connector 13 protrudes as an outer magnetic clasp 32. The outer magnetic clasp 32 is inserted into the guide groove 2116 and magnetically connected to the inner magnetic clasp 32. The guide groove 2116 can guide the male magnetic clasp 131 during the insertion of the connector 3.

[0061] Of course, in other embodiments, the female connector 211 may be disposed at the plug end 1 and the male connector 13 may be disposed at the handle end 2; or the connector assembly may be a threaded or bayonet-type connector assembly.

[0062] Please refer to handle end 2. Figure 1 and Figure 3 It includes a handle housing 22, a handle electrical control 26, a trigger, and a bushing assembly 24.

[0063] like Figure 3 As shown, a first handle end face 21 is provided at one end of the handle housing 22, and a female connector 211 is fixed to one end of the handle housing 22. The female connector 211 is electrically connected to the handle electrical control 26 inside the handle housing 22. The handle housing 22 specifically includes a first half-shell 221 and a second half-shell 222 that interlock, facilitating the assembly of the structures inside the handle housing 22. Figure 7As shown, a housing seal 227 is provided at the snap-fit ​​joint of the first half-shell 221 and the second half-shell 222. Specifically, it can be a sealant or a sealing strip to improve the sealing and waterproof performance of the handle housing 22.

[0064] Specifically, such as Figure 3 As shown, the first half-shell 221 and the second half-shell 222 are sequentially arranged in the second direction Y, which can be perpendicular to the first direction X. In this case, both the first half-shell 221 and the second half-shell 222 are semi-ring structures, which are fastened together to form a ring structure that runs through the first direction X. Of course, in other embodiments, the first half-shell 221 and the second half-shell 222 can also be ring structures, which are connected in the first direction X to form the entire handle shell 22. In this case, after assembling the corresponding structures in the shorter first half-shell 221 and the second half-shell 222 respectively, the first half-shell 221 and the second half-shell 222 are then connected together.

[0065] Specifically, such as Figure 7 As shown, the snap-fit ​​joints of the first half-shell 221 and the second half-shell 222 are provided with matching stepped surfaces 223. The stepped design also forms a waterproof structure, further improving the waterproof effect. The different stepped surfaces on the stepped surface 223 are arranged sequentially from the inside to the outside of the handle housing 22.

[0066] Specifically, such as Figure 7 As shown, a first fitting gap 224 is reserved at the snap-fit ​​joint of the first half-shell 221 and the second half-shell 222. Epoxy adhesive is filled in the first fitting gap 224 to serve as a shell seal 227. In addition, the first fitting gap 224 can be located on the side of the snap-fit ​​joint of the first half-shell 221 and the second half-shell 222 near the inner cavity of the handle shell 22 to ensure the cleanliness of the handle shell 22's appearance.

[0067] like Figures 7 to 11 As shown, the trigger is located in the mounting hole 225 on the handle housing 22. The trigger moves to activate the handle electrical control 26, thereby starting the shock wave operation handle and releasing a high-voltage pulse. The trigger and the mounting hole 225 are sealed together to prevent liquid from entering the handle housing 22 through the space between the trigger and the mounting hole 225.

[0068] Specifically, such as Figure 9 and Figure 10As shown, the trigger includes a button assembly 23, which includes a button cap 231 and a trigger rod 233. The button cap 231 is waterproof and can be made of silicone. A button sealing ring 232 is provided between the button cap 231 and the mounting hole 225. The button sealing ring 232 and the mounting hole 225 achieve waterproofing through an interference fit. The button cap 231 wraps around the end of the trigger rod 233 away from the handle housing 22 and seals the mounting hole 225. The other end of the trigger rod 233 extends into the handle housing 22. The button cap 231 drives the trigger rod 233 to slide into the handle housing 22, thereby triggering the handle electronic control 26.

[0069] The button cap 231 can be an elastic element, and the trigger rod 233 is connected to the button cap 231. Specifically, it can be embedded in the button cap 231. The elastic return of the button cap 231 drives the trigger rod 233 to slide outwards from the handle housing 22 to reset. Alternatively, the button assembly 23 can also include a spring disposed in the button cap 231. The spring is connected to the trigger rod 233. The spring's return causes the trigger rod 233 to slide outwards from the handle housing 22 to reset.

[0070] Specifically, such as Figure 9 and Figure 10 As shown, the button sealing ring 232 is integrally formed on the outer surface of the button cap 231. In this case, the button cap 231 also serves a sealing function. The button cap 231 can then directly achieve a sealing fit with the mounting hole 225, reducing assembly steps.

[0071] Among them, such as Figure 10 As shown, the button sealing ring 232 is set on the end of the button cap 231 near the inside of the handle housing 22. Since the part of the button cap 231 away from the inner cavity of the handle housing 22 is mainly pressed when it is pressed, this setting can avoid the button sealing ring 232 affecting the pressing deformation of the button cap 231 and can also prevent the button sealing ring 232 from moving and affecting the sealing effect.

[0072] Among them, such as Figure 10 As shown, the button sealing ring 232 can be set on the outer peripheral surface of the button cap 231. The outer peripheral surface of the button is the surface in the direction of movement around the trigger rod 233. It can also be set on the end face of the button cap 231 near the inner cavity of the handle housing 22. This end face is in contact with the support surface 226 on the mounting hole 225 facing the outside of the handle housing 22.

[0073] Specifically, such as Figure 10As shown, a locking nut 25 is also provided inside the handle housing 22. The button assembly 23 also includes a button seat 234 connected to the button cap 231. The button seat 234 is threaded to the locking nut 25. The trigger rod 233 is slidably inserted into the button seat 234. The assembly of the button assembly 23 and the handle housing 22 is achieved through the threaded connection, which is convenient for operation.

[0074] Among them, such as Figure 10 As shown, the locking nut 25 is fixed to the inner wall of the handle housing 22. Specifically, it can be integrally formed on the handle housing 22, or it can be separately glued or welded to the handle housing 22.

[0075] Among them, such as Figure 10 As shown, part of the structure of the button base 234 can extend into the button cap 231. At this time, the button base 234 and the button cap 231 form a closed cavity to accommodate one end of the trigger rod 233 connected to the button cap 231 and to provide space for the trigger rod 233 to move. Part of the structure of the button base 234 abuts against the support surface 226 of the mounting hole 225.

[0076] like Figure 11 As shown, the bushing assembly 24 is used to protect the cable 27 of the handle control 26 and is connected to both ends of the handle housing 22, respectively, along with the plug end 1.

[0077] Specifically, such as Figure 11 As shown, the bushing assembly 24 is connected to the handle housing 22. The cable 27 of the handle control 26 extends through the bushing assembly 24, and the cable 27 is interference-fitted with the bushing assembly 24. Specifically, the interference fit can be made at the end of the bushing assembly 24 away from the handle housing 22. Waterproofing is achieved at this point through the interference fit between the cable 27 and the handle housing 22.

[0078] Specifically, the bushing assembly includes a main bushing structure, which comprises a rigid skeleton 243 and a soft layer 244 covering the rigid skeleton 243. That is, the inner layer of the main bushing structure is the rigid skeleton 243, specifically a ring-shaped structure, and the outer layer is the soft layer 244, which has a lower hardness than the inner layer. The cable 27 is interference-fitted with the soft layer 244. In this case, the rigid skeleton 243 provides support, and the soft layer 244 ensures a seal between itself and the cable 27, preventing damage to the cable 27.

[0079] Specifically, such as Figure 11 As shown, the bushing assembly 24 near the handle housing 22 is also provided with a rigid sleeve 245, which can be fixedly installed at one end of the main sleeve structure in the first direction X. By adding the rigid sleeve 245, the connection between the bushing assembly 24 and the handle housing 22 is less prone to fish-mouth-shaped deformation under stress, which is beneficial for waterproofing.

[0080] The soft layer 244 can be made of soft materials such as silicone, rubber, or soft PE (Polyethylene). The rigid skeleton 243 and rigid sleeve 245 can be made of rigid plastic parts such as PS (Polystyrene), ABS (Acrylonitrile Butadiene Styrene), or rigid PVC (Polyvinyl Chloride).

[0081] To improve waterproofing, a bushing seal 242 is provided at the connection between the bushing assembly 24 and the handle housing 22. This seal can be either sealant or a sealing ring. Specifically, the bushing assembly 24 and the handle housing 22 are inserted into each other, with a second fitting gap 241 reserved at the insertion point, which is filled with epoxy adhesive as the bushing seal 242.

[0082] The shockwave operating handle provided in this embodiment is applied to an intravascular shockwave system. Sealing is implemented at the connection points of the plug end 1 and the handle end 2, the mating point between the trigger element and the handle housing 22, the mating point between the first half-shell 221 and the second half-shell 222 of the handle housing 22, the mating point between the bushing assembly 24 and the handle housing 22, and the mating point between the cable 27 and the bushing assembly 24.
