Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an implantable device delivery device and an implantable device placement kit equipped with the implantable device delivery device. Background Technology

[0002] Existing implantable devices (such as self-expanding stents) are placed as follows: the device is compressed within a delivery sheath and delivered to the vascular lesion. The sheath is then retracted to release the device, allowing it to adhere to the vessel wall through its own expansion tension and the elasticity of the vessel wall. However, this method has drawbacks: once the device is fully released from the sheath, the lack of a mechanism to maintain connection with the delivery system means that if displacement or mispositioning occurs, the operator cannot easily and promptly readjust the device's position or retract it back into the sheath by manipulating the delivery system, posing risks to the implantation procedure. Summary of the Invention

[0003] To address the aforementioned problems, the main objective of this invention is to provide an implantable device delivery device capable of positioning and / or retrieving an implantable device after it has been fully released from the sheath.

[0004] Another objective of this invention is to provide an implantation device installation kit equipped with the aforementioned implantation device delivery device.

[0005] To achieve the main objective of this utility model, it provides an implantable device delivery device, comprising a mandrel assembly, a cable assembly, and a handle assembly. The mandrel assembly includes a locking head and a mandrel, with the locking head connected to the first end of the mandrel. The cable assembly includes a retainer and a hollow cable. The retainer has a cavity and two or more slots. The cavity extends through the retainer in the extending direction of the cable assembly. The two or more slots are distributed circumferentially along the retainer. The slots extend from the first end face of the retainer to the second end of the retainer in the extending direction, penetrating the cavity wall. The second end of the retainer is connected to the first end of the hollow cable, and the cavity communicates with the hollow cable. The handle assembly includes a body, an operating handle, and an elastic element. The body has a channel extending through the body in the length direction. The second end of the hollow cable is connected to the first end of the body and communicates with the channel. The operating handle is slidably sleeved on the second end of the body. The second end of the mandrel passes through the cavity, the hollow cable, and the channel and is connected to the operating handle. The elastic element is connected between the operating handle and the body, forcing the operating handle to move away from the body so that the locking head and the retainer form a clamping position.

[0006] As can be seen above, the mandrel assembly is guided and supported by the cable assembly. The handle assembly moves relative to the main body by manipulating the operating handle to pull or push the mandrel assembly, thereby controlling the locking head to abut against the holder. This engages with the limiting part on the implantable device to lock the implantable device onto the holder, facilitating re-insertion and readjustment of the implantable device to the desired position. Alternatively, the locking head can be separated from the holder to a first preset distance to keep the implantable device in a loaded state, at which point it can be further released or relocked. Or, the locking head can be separated from the holder to a second preset distance to release the loaded and clamped implantable device (such as a stent). The elastic element allows the operating handle to pull the mandrel assembly to control the locking head abutting against the holder, eliminating the need for manual control by the operator when the implantable device is locked, thus improving the convenience and accuracy of implantable device movement and position adjustment. The design of the implantable device delivery device allows for positioning adjustment and / or re-entry into the sheath of the implantable device after it has been completely released from the sheath.

[0007] In a preferred embodiment, the spindle assembly further includes a release pusher, which is fitted onto the spindle and has a storage gap between the release pusher and the locking head, allowing the release pusher to be stored within the cavity.

[0008] As can be seen from the above, the release pusher can work with the limiting part of the implanted device to push the implanted device away from the holder when releasing the implanted device, making the release of the implanted device more reliable and convenient, and at the same time helping to reduce intraoperative risks.

[0009] A further design is that the outer contour surface of the locking head is a smooth arc surface; the side of the release push block facing the locking head is flat; the release push block is shaped like a frustum, with the large-diameter end of the release push block located between the locking head and the small-diameter end of the release push block.

[0010] As can be seen from the above, making the outer contour surface of the locking head smooth can avoid damage to human tissue and reduce intraoperative risks; while designing the side of the release pusher facing the locking head as a flat surface can help the release pusher better push the limiting part of the implanted instrument so that the implanted instrument is completely separated from the card seat.

[0011] Another preferred embodiment is that the operating handle has a blind cavity and a socket. The blind cavity extends from the first end of the operating handle toward the second end of the operating handle in the length direction, and the socket extends from the bottom of the blind cavity toward the second end of the operating handle in the length direction. The second end of the main body is slidably inserted into the blind cavity, and the spindle also passes through the blind cavity and is inserted into the socket. An elastic element is disposed in the blind cavity, and the two ends of the elastic element abut against the second end face of the main body and the bottom surface of the blind cavity, respectively.

[0012] As can be seen from the above, this design helps to optimize the structure of the handle assembly, making the handle assembly structure simpler and more reliable.

[0013] A further option is to use a compression spring or a spring plunger as the elastic element.

[0014] As can be seen from the above, the design of the elastic element enables it to stably and reliably force the operating handle to move away from the main body.

[0015] Another further option is that the cavity wall of the blind cavity is provided with a longitudinal groove and three or more circumferential grooves. The longitudinal groove extends along the length direction, and the three or more circumferential grooves are distributed along the longitudinal groove. The circumferential grooves extend along the circumference of the operating handle and communicate with the longitudinal groove. A limiting pin is provided on the main body, and the limiting pin can switch positions between the longitudinal groove and each circumferential groove.

[0016] As can be seen from the above, the design of the longitudinal groove, circumferential groove and limiting pin can enable the implantation device delivery device to control the implantation device to remain in the locked state, at least one loaded state and released state; at the same time, the cooperation of the longitudinal groove, circumferential groove and limiting pin can also limit the sliding and rotation between the main body and the operating handle to prevent the main body and the operating handle from separating.

[0017] Another further embodiment is that the operating handle also has a connection hole that extends from the outer peripheral wall of the operating handle to the socket and communicates with the socket; the handle assembly also includes a bolt that connects to the connection hole and abuts against the spindle.

[0018] As can be seen from the above, this design facilitates the disassembly and assembly of the mandrel assembly, thereby making it easier to assemble the implantable device delivery device and maintain and replace the mandrel assembly.

[0019] Another preferred embodiment is that the second end of the card holder has a frustum, with the large-diameter end of the frustum located between the first end of the card holder and the small-diameter end of the frustum; the main body and / or the operating handle are provided with an anti-slip structure.

[0020] As can be seen from the above, the design of the card holder facilitates the retraction of the cable guide assembly and spindle assembly into the sheath; and the anti-slip structure on the main body and / or operating handle allows the operator to more reliably control the movement of the operating handle relative to the main body.

[0021] A further embodiment is that the locking head is welded to the spindle, or the locking head is threaded to the spindle; the spindle is made of at least one first wire, which is made of stainless steel or polymer material; the card holder is welded to the hollow cable, or the card holder is threaded to the hollow cable; the card holder is made of stainless steel or polymer material; the hollow cable is made of at least one second wire, which is made of stainless steel or polymer material.

[0022] As can be seen from the above, the design helps to improve the reliability and safety of the implantable device delivery device.

[0023] To achieve the main objective of this utility model, this utility model provides an implantation device placement kit, including a sheath, which further includes the aforementioned implantation device delivery device, a mandrel assembly and a cable assembly that can extend into and / or out of the sheath.

[0024] As can be seen from the above, the implantable device placement kit, by setting up the aforementioned implantable device delivery device, enables it to position and adjust the implantable device after it has been completely released from the sheath and / or retract it back into the sheath during the placement of the implantable device.

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0034] Example of an implantable device delivery device

[0035] Reference Figure 1 and Figure 2 The implantable device delivery device 100 includes a spindle assembly 1, a cable assembly 2, and a handle assembly 3.

[0036] Combination Figure 3The spindle assembly 1 includes a locking head 11, a spindle 12, and a release push block 13. The locking head 11 is connected to the first end of the spindle 12. Preferably, the locking head 11 and the spindle 12 can be fixed by welding, or the locking head 11 and the spindle 12 can be fixed by threaded connection to ensure the reliability of the connection between the locking head 11 and the spindle 12. Of course, other fixing methods can also be used between the locking head 11 and the spindle 12, so they will not be described in detail here.

[0037] Furthermore, the outer contour surface of the locking head 11 is preferably a smooth arc surface to avoid damage to human tissue, thereby reducing intraoperative risks. Preferably, the locking head 11 can be designed as a sphere. The locking head 11 is preferably made of stainless steel or polymer material to ensure its reliability and safety in use.

[0038] The mandrel 12 is wound from at least one first wire 121. Preferably, the number of first wires 121 is between two and four. The first wires 121 are made of stainless steel or polymer material to ensure that the mandrel 12 has moderate flexibility, so that the mandrel 12 can control the locking head 11 to cooperate with the card holder 21 of the cable guide assembly 2 to lock or release the implanted device 10 (such as a stent), and ensure the reliability and safety of the mandrel 12.

[0039] The release pusher 13 is fitted onto and fixedly connected to the mandrel 12, such that the release pusher 13 is located between the locking head 11 and the second end of the mandrel 12. Preferably, the release pusher 13 is welded to the mandrel 12, and the release pusher 13 is preferably made of stainless steel or polymer material. Furthermore, there is a receiving gap between the release pusher 13 and the locking head 11, which is used to accommodate the limiting portion 101 of the implantable device 10. The release pusher 13, when releasing the implantable device 10, works in conjunction with the limiting portion 101 of the implantable device 10 to push the implantable device 10 away from the holder 21, making the release of the implantable device 10 more reliable and convenient, and helping to reduce intraoperative risks.

[0040] Preferably, the side of the release pusher 13 facing the locking head 11 is designed as a flat surface 131, which facilitates the release pusher 13 in better pushing the limiting part 101 of the implantation device 10 out of the holder 21, thereby completely separating the implantation device 10 from the holder 21. Further, the release pusher 13 can be designed in a frustum-like shape, wherein the large-diameter end of the release pusher 13 is located between the locking head 11 and the small-diameter end of the release pusher 13; this design helps the release pusher 13 to be more smoothly retracted into the holder 21.

[0041] The cable guide assembly 2 includes a retainer 21 and a hollow cable guide 22; the retainer 21 has a cavity 211 and a slot 212, wherein the cavity 211 extends through the retainer 21 in the extending direction of the cable guide assembly 2, and the number of slots 212 is two or more, and the two or more slots 212 are distributed along the circumference of the retainer 21. For example, in this embodiment, the number of slots 212 is three. The slot 212 extends from the first end face of the card holder 21 along the extension direction of the cable guide assembly 2 to the second end of the card holder 21, and the slot 212 penetrates the cavity wall of the cavity 211, so that the slot 212 communicates with the cavity 211; the slot 212 is used to cooperate with the limiting part 101 on the implantation device 10. When cooperating, the limiting part 101 on the implantation device 10 passes through the slot 212, and the limiting block 1011 on the limiting part 101 is located in the cavity 211 of the card holder 21; it should be noted that the limiting block 1011 on the limiting part 101 is larger than the width of the slot 212, so that the limiting block 1011 cannot pass through the slot 212.

[0042] The second end of the retainer 21 is connected to the first end of the hollow cable 22, and the cavity 211 communicates with the hollow cable 22. The retainer 21 and the hollow cable 22 are preferably fixed by welding. However, as other options, the retainer 21 and the hollow cable 22 can also be fixed by threaded connection, interference fit (such as providing a slot on the second end of the retainer 21 so that one end of the spindle 12 is interference-fitted into the slot; it should be noted that this interference fit can be used in conjunction with welding), and other fixing methods.

[0043] The card holder 21 is preferably made of stainless steel or polymer material; in addition, a frustum 213 is preferably provided at the second end of the card holder 21, and the large diameter end of the frustum 213 is located between the first end of the card holder 21 and the small diameter end of the frustum 213. This design is beneficial for the cable guide assembly 2 and the spindle assembly 1 to be retracted into the sheath.

[0044] The hollow cable 22 is wound from at least one second filament 221. The winding can be tight or can be changed according to the required flexibility of the hollow cable 22; in this embodiment, the number of second filaments 221 is one. The second filament 221 is made of stainless steel or polymer material.

[0045] Combination Figure 4 The handle assembly 3 includes a body 31, an operating handle 32, and an elastic element 33. The body 31 has a channel 311 that extends through the body 31 along its length; wherein, the second end of the hollow guide cable 22 is connected to the first end of the body 31 and communicates with the channel 311.

[0046] The operating handle 32 is slidably sleeved on the second end of the main body 31. The second end of the spindle 12 passes through the cavity 211, the hollow guide cable 22, and the channel 311 and is connected to the operating handle 32, so that the operating handle 32 can operate the spindle assembly 1 to move relative to the main body 31, thereby causing the locking head 11 to contact the first end of the card seat 21 and the release push block 13 to be stored in the cavity 211, or causing the locking head 11 to separate from the first end of the card seat 21 and the release push block 13 to be stored in the cavity 211, or causing the locking head 11 to separate from the first end of the card seat 21 and the release push block 13 to move to the outside of the cavity 211, etc.

[0047] Preferably, the operating handle 32 has a blind cavity 321 and a socket 322; wherein the blind cavity 321 extends from the first end of the operating handle 32 toward the second end of the operating handle 32 in the length direction of the body 31, and the socket 322 extends from the bottom of the blind cavity 321 toward the second end of the operating handle 32 in the length direction of the body 31.

[0048] When the operating handle 32 is assembled with the main body 31, the second end of the main body 31 is slidably inserted into the blind cavity 321. At this time, the operating handle 32 can also rotate relative to the main body 31 around the axis of the main body 31. The spindle 12 passes through the blind cavity 321 after passing through the channel 311 of the main body 31 and is inserted into the socket 322.

[0049] As an alternative, when the mandrel 12 is inserted into the insertion hole 322, the mandrel 12 and the insertion hole 322 are interference-fitted. As another alternative and preferred method, as in this embodiment, a connecting hole 323 is provided on the operating handle 32, and the connecting hole 323 extends from the outer peripheral wall of the operating handle 32 towards the insertion hole 322 until it communicates with the insertion hole 322; at the same time, the handle assembly 3 is also provided with a bolt 34, which is connected to the connecting hole 323, and the screw end of the bolt 34 abuts against the mandrel 12 to fix the mandrel 12 on the operating handle 32; this design facilitates the disassembly and assembly of the mandrel assembly 1, thereby facilitating the assembly of the implantable device delivery device 100 and the maintenance and replacement of the mandrel assembly 1; wherein, the axis of the connecting hole 323 is preferably approximately perpendicular to the axis of the insertion hole 322 to ensure the locking and fixing effect of the bolt 34 on the mandrel 12.

[0050] An elastic element 33 is connected between the operating handle 32 and the main body 31. The elastic element 33 is used to force the operating handle 32 to move away from the main body 31, so that the locking head 11 and the locking seat 21 form a clamping position. Preferably, the elastic element 33 can be disposed in the blind cavity 321 of the operating handle 32, and the two ends of the elastic element 33 abut against the second end face of the main body 31 and the bottom surface of the blind cavity 321, respectively. This design helps to optimize the structure of the handle assembly 3, making the structure of the handle assembly 3 simpler and more reliable. The elastic element 33 is a compression spring, so that the elastic element 33 can stably and reliably force the operating handle 32 to move away from the main body 31; of course, as another optional solution, the elastic element 33 can also be a spring plunger.

[0051] Combination Figure 5 The blind cavity 321 of the operating handle 32 has a longitudinal groove 3211 and three or more circumferential grooves 3212 on its cavity wall. The longitudinal groove 3211 extends along the length direction, and the three or more circumferential grooves 3212 are distributed along the longitudinal groove 3211. The circumferential grooves 3212 extend along the circumference of the operating handle 32 and communicate with the longitudinal groove 3211. The main body 31 is provided with a limiting pin 312, which can switch positions between the longitudinal groove 3211 and each of the circumferential grooves 3212. Preferably, both the longitudinal groove 3211 and the circumferential grooves 3212 penetrate the cavity wall of the blind cavity 321, and the limiting pin 312 penetrates either the longitudinal groove 3211 or the circumferential groove 3212.

[0052] In this embodiment, there are three circumferential grooves 3212, and the longitudinal groove 3211 and the three circumferential grooves 3212 are arranged in an "E" shape. The three circumferential grooves 3212 can respectively correspond to the three states of locking, loading, and releasing of the implantable device delivery device 100 to the stent; wherein, as shown... Figure 5 As shown, the leftmost circumferential groove 3212 (i.e., the circumferential groove 3212 closest to the locking head 11) corresponds to the locking state of the implantation device delivery device 100 with respect to the stent, the middle circumferential groove 3212 corresponds to the loading state of the implantation device delivery device 100 with respect to the stent, and the rightmost circumferential groove 3212 (i.e., the circumferential groove 3212 furthest from the locking head 11) corresponds to the releasing state of the implantation device delivery device 100 with respect to the stent.

[0053] It should be noted that, as one of the alternative options, there can be more than four circumferential grooves 3212. For example, there are four circumferential grooves 3212. The leftmost circumferential groove 3212 (i.e., the circumferential groove 3212 closest to the locking head 11) still corresponds to the locking state of the implantation device delivery device 100 on the stent, the rightmost circumferential groove 3212 (i.e., the circumferential groove 3212 furthest from the locking head 11) still corresponds to the releasing state of the implantation device delivery device 100 on the stent, and the two circumferential grooves 3212 in the middle correspond to different loading states of the implantation device delivery device 100 on the stent. As another alternative, along the extension direction of the longitudinal groove 3211, the leftmost circumferential groove 3212 (i.e., the circumferential groove 3212 closest to the locking head 11) is not located at the leftmost end of the longitudinal groove 3211 (i.e., the end closest to the locking head 11), and the rightmost circumferential groove 3212 (i.e., the circumferential groove 3212 furthest from the locking head 11) is not located at the rightmost end of the longitudinal groove 3211 (i.e., the end furthest from the locking head 11).

[0054] Preferably, the longitudinal groove 3211 and the three (or more) circumferential grooves 3212 described above constitute a groove group. Two such groove groups can be provided on the operating handle 32, and these two groove groups are centrally symmetrically arranged along the circumference of the operating handle 32. Correspondingly, there are two limiting pins 312 on the main body, which are centrally symmetrically arranged along the circumference of the main body, and each limiting pin 312 corresponds one-to-one with one of the two groove groups. Furthermore, the main body 31 is also provided with an anti-slip structure 313, and / or the operating handle 32 is provided with an anti-slip structure 324.

[0055] By designing the longitudinal groove 3211, the circumferential groove 3212, and the limiting pin 312, the implantation device delivery device 100 can control the implantation device 10 to remain in a locked state, at least one loaded state, and a released state; at the same time, the cooperation of the longitudinal groove 3211, the circumferential groove 3212, and the limiting pin 312 can also limit the sliding and rotation between the main body 31 and the operating handle 32 to prevent the main body 31 and the operating handle 32 from separating.

[0056] The following combination Figures 6 to 8 A brief description of the use of the implantable device delivery device 100:

[0057] When it is necessary to load the implantable device 10, the operating handle 32 of the operating handle assembly 3 switches the implantable device delivery device 100 to the loading state (e.g., ...). Figure 7As shown), at this time, the locking head 11 of the spindle assembly 1 separates from the first end of the retainer 21 of the cable guide assembly 2, and the release push block 13 of the spindle assembly 1 is located in the cavity 211 of the retainer 21. From this position, the limiting part 101 of the implantation device 10 can be placed between the locking head 11 and the release push block 13, thereby allowing the implantation device delivery device 100 to switch to the locked state (as shown). Figure 6 When the implantation device 10 is inserted into the slot 212 of the holder 21 of the cable guide assembly 2 (as shown), the limiting part 101 of the limiting part 101 of the implantation device 10 can be inserted into the cavity 211 of the holder 21, and the limiting block 1011 of the limiting part 101 of the implantation device 10 can be housed in the cavity 211 of the holder 21. When the operating handle 32 controls the implantation device delivery device 100 to switch to the loading state, the limiting pin 312 on the main body 31 can be moved into the corresponding circumferential groove 3212 when the operating handle 32 is rotated, so that the implantation device delivery device 100 is stably maintained in the loading state.

[0058] When it is necessary to lock the implantable device 10, the operating handle 32 of the operating handle assembly 3 switches the implantable device delivery device 100 to the locked state. At this time, the locking head 11 contacts the first end of the holder 21, and the release push block 13 is located in the cavity 211 of the holder 21. The limiting part 101 of the implantable device 10 is inserted into the slot 212 of the holder 21, and the limiting block 1011 of the limiting part 101 is housed in the cavity 211 of the holder 21. At this time, the implantable device 10 can be operated by the implantable device delivery device 100 to move out of the sheath and to adjust the positioning of the implantable device 10 and / or to retract the implantable device 10 back into the sheath until the operator is satisfied with the position of the implantable device 10.

[0059] After the implantation device 10 has been fully ejected from the sheath and placed in the designated position, the operating handle 32 of the operating handle assembly 3 switches the implantation device delivery device 100 to the release state (e.g., ...). Figure 8 As shown, at this time, the locking head 11 separates from the first end of the card holder 21, and the release push block 13 is located outside the cavity 211 of the card holder 21. The limiting part 101 of the implanted device 10 is pushed away from the card slot 212 of the card holder 21 by the release push block 13, and the limiting block 1011 of the limiting part 101 is completely pushed out of the cavity 211 of the card holder 21, thereby completing the release of the implanted device 10.

[0060] In summary, by designing the implantable device delivery device 100 to position and / or retract the implantable device 10 after it has been completely released from the sheath, the implantation risk is reduced.

[0061] Example of an implantable device placement kit

[0062] The implantable device placement kit includes a sheath and the implantable device delivery device described in the aforementioned implantable device delivery device assembly; wherein the spindle assembly and cable assembly of the implantable device delivery device can extend into and / or out of the sheath. By incorporating the aforementioned implantable device delivery device, the implantable device placement kit allows for positioning and / or retraction of the implantable device after it has been fully released from the sheath, during implantation.

[0063] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
