Description

Technical Field

[0001] This application relates to the field of medical surgical equipment technology, and in particular to an interventional surgical system and a vascular interventional device. Background Technology

[0002] For cardiovascular interventional procedures, the operator must wear a lead apron and inject contrast agents, heparin, and saline solution using a pressure pump at different stages of the procedure, remaining in a radiation environment throughout. Operating the pressure pump is challenging because its maximum operating pressure is 30 atmospheres, making pressurization difficult and requiring constant monitoring of the pressure gauge. Withdrawing the balloon requires rapid, repeated pushing and pulling of the pressure pump plunger to ensure the balloon retracts to the desired shape. Incomplete balloon retraction can damage blood vessels, making this a highly demanding step that tests the operator's skill.

[0003] In current cardiovascular interventional procedures, the operator needs to manually operate the pressure pump. However, due to its threaded propulsion design, the pressure pump has a limited propulsion speed and low pressurization efficiency when manually operated. Furthermore, the instability of manual operation during balloon withdrawal may lead to unsatisfactory balloon retraction, potentially damaging blood vessels and affecting the safety of the procedure. Summary of the Invention

[0004] Therefore, it is necessary to address the problems of low pressure boosting efficiency and instability caused by manual operation of pressure pumps in current vascular interventional procedures, and to provide an interventional surgical system and vascular interventional device that can automatically achieve pressure boosting and depressurization, ensuring pressure boosting efficiency and stability.

[0018] In one embodiment of this application, the vascular interventional device further includes an injection structure, which includes a syringe, a connecting mechanism, and an injection driving mechanism. The syringe includes a second barrel and a second piston rod, the second piston rod being telescopically disposed in the second barrel. The second barrel is connected to the connecting mechanism, and an infusion tube is externally connected to the connecting mechanism. The injection driving mechanism is electrically connected to the remote control console, and the remote control console controls the injection driving mechanism to drive the second piston rod to move, so that the connecting mechanism can perform an injection operation.

[0019] In one embodiment of this application, the injection driving mechanism includes a fourth driving member, a third lead screw member, and a connecting member. The connecting member is disposed at the end of the second piston rod, and the third lead screw member connects the connecting member and the fourth driving member.

[0020] In one embodiment of this application, the injection driving mechanism further includes a third limiting member disposed opposite to the remote control console. The third limiting member is electrically connected to the remote control console. The third lead screw has a third mating member. The third lead screw drives the third mating member to move between the third limiting members and is limited by the third limiting members.

[0021] In one embodiment of this application, the connecting mechanism includes a clamping block, a three-way valve, a fifth driving member, and a sixth driving member.

[0027] By adopting the above technical solution, this application has at least the following technical effects:

[0028] The interventional surgical system and vascular interventional device of this application, in which a pressure regulating structure controls the decompression and contraction of a balloon through the cooperation of a pressure pump and a rapid decompression mechanism, wherein the first piston rod of the pressure pump is disposed in a first cylinder, the outer wall of the first piston rod having locally distributed external threads, and the first cylinder having internal threads. A first drive assembly of the rapid decompression structure is drivenly connected to the first piston rod, and a second drive assembly is drivenly connected to the first cylinder. An unlocking handle is disposed on the first piston rod. When the pressure pump unlocks, a remote control console controls the first drive assembly to drive the first piston rod, causing the unlocking handle to move, separating the external threads of the first piston rod from the internal threads of the first cylinder, thus releasing the pressure in the pressure pump and reducing the pressure inside the first cylinder to zero. The second drive assembly drives the first cylinder to reciprocate relative to the first piston rod to rapidly decompress the pressure pump, causing the pressure pump to control the balloon contraction. The remote control console is electrically connected to the first and second drive assemblies to remotely control the pressure regulating structure's operation of the pressure pump.

[0029] This vascular interventional device achieves balloon withdrawal through the cooperation of a first drive component and a second drive component. During balloon withdrawal, the first drive component first controls the unlocking handle to unlock the first piston rod and the first cylinder, ensuring the stability of the pressure pump unlocking. Then, the second drive component controls the reciprocating movement of the first cylinder relative to the first piston rod to control balloon contraction, thereby ensuring the balloon contracts to an ideal state for easy withdrawal from the blood vessel and ensuring the safety of the interventional procedure. Furthermore, remote control of the pressure regulation structure is achieved via a remote control console, eliminating the need for the operator to enter the operating room and reducing radiation exposure.

[0043] See Figure 1 and Figure 2This application provides a vascular interventional device 10. This vascular interventional device 10 is used in an interventional surgical system to control the expansion and contraction of a balloon during the interventional procedure. After expansion, the balloon can move a stent to support it at the target location in the blood vessel. Once the stent is supported at the target location, the vascular interventional device 10 can control the balloon to contract, facilitating the withdrawal of the balloon from the blood vessel. Furthermore, the vascular interventional device 10 can also be used to inject contrast agents, heparin, etc. Figure 1 This is a usage scenario diagram of the vascular interventional device 10 according to an embodiment of this application applied to an interventional surgery system. Figure 2 for Figure 1 A three-dimensional view of the vascular interventional device 10 shown.

[0044] Understandably, current cardiovascular interventional procedures require manual operation of the pressure pump. However, due to its threaded propulsion design, the pressure pump has limited propulsion speed and low pressurization efficiency under manual operation. Furthermore, the instability of manual operation during balloon withdrawal can lead to unsatisfactory balloon retraction and damage to blood vessels, affecting the safety of the procedure. Therefore, this application provides a novel vascular interventional device 10 that can automatically control pressurization and depressurization operations, ensuring the stability and efficiency of pressurization and depressurization, thereby ensuring that the balloon retracts to an ideal state, facilitating balloon withdrawal from the blood vessel, and ensuring the safety of the interventional procedure. The specific structure of a vascular interventional device 10 according to one embodiment is described below.

[0045] See Figures 1 to 4 In one embodiment, the vascular interventional device 10 includes a pressure regulating structure 100 and a remote control console 300. The pressure regulating structure 100 includes a pressure pump 110 and a rapid pressure relief mechanism (not shown). The rapid pressure relief mechanism includes an unlocking handle 120, a first drive assembly 140, and a second drive assembly 150. The pressure pump 110 includes a first cylinder 111 and a first piston rod 112. The first piston rod 112 has locally distributed external threads 1121. The first cylinder 111 has internal threads that engage with the external threads 1121. The unlocking handle 120 is disposed on the first piston rod 112. The first drive assembly 140 is driveably connected to the first piston rod 112, and the second drive assembly 150 is driveably connected to the first cylinder 111. The remote control console 300 controls the connection between the first drive assembly 140 and the second drive assembly 150. The first drive assembly 140 drives the first piston rod 112 to unlock the unlocking handle 120, causing the internal thread of the first cylinder 111 to separate from the external thread 1121 of the first piston rod 112, thereby unlocking the first cylinder 111 and the first piston rod 112 and reducing the pressure inside the first cylinder 111 to zero. The second drive assembly 150 drives the first cylinder 111 to reciprocate relative to the first piston rod 112 for rapid pressure relief. Figure 3 for Figure 2A schematic diagram of the pressure regulation structure 100 in the vascular interventional device 10 is shown. Figure 4 for Figure 3 A partial schematic diagram of the engagement between the first piston rod 112 and the first cylinder 111 in the pressure regulating structure 100 shown.

[0046] The pressure regulating structure 100 is a component for regulating balloon pressure. Within the pressure regulating structure 100, a rapid depressurization mechanism is connected to the pressure pump 110 to control the unlocking and rapid depressurization of the pressure pump 110. The remote control console 300 is a remote controller for the vascular interventional device 10. The remote control console 300 is electrically connected to the driving components of the pressure regulating structure 100, namely the first driving assembly 140 and the second driving assembly 150, so that the first driving assembly 140 and the second driving assembly 150 perform corresponding operations. It is understood that the remote control console 300 is electrically connected to the first driving assembly 140 and the second driving assembly 150 via connecting wires, thus increasing the distance between the remote control console 300 and the pressure regulating structure 100, allowing the pressure regulating structure 100 and the remote control console 300 to be located in different rooms. Thus, in actual use, the pressure regulating structure 100 of the vascular interventional device 10 is located in the operating room. The operator can operate the remote control console 300 from a room outside the operating room, such as an operating room / observation room, to control the movement of the pressure regulating structure 100, thereby reducing the radiation impact on the operator during angiography. Of course, in other embodiments of this application, the remote control console 300 can also be connected to the first drive component 140 and the second drive component 150 via wireless transmission.

[0047] The outer wall of the first piston rod 112 has locally distributed external threads 1121, and the inner wall of the first cylinder 111 has internal threads. The first piston rod 112 is installed in the first cylinder 111. The external threads 1121 and the internal threads cooperate with each other, allowing the first piston rod 112 to rotate relative to the first cylinder 111, thereby enabling the pressure pump 110 to pressurize. After the pressure pump 110 pressurizes, it can expand the balloon, causing the balloon to drive the stent to expand, and thus supporting the stent at the target position of the blood vessel. Optionally, in the circumferential direction, the arc length of the external threads 1121 is 1 / 4 to 1 / 2 of the circumference of the first piston rod 112. Optionally, the internal threads are provided on the inner wall of the first cylinder 111 corresponding to the external threads 1121, or they can cover the entire inner wall of the first cylinder 111.

[0048] It is worth noting that after the stent is positioned at the target location, the balloon needs to be withdrawn from the blood vessel. To facilitate withdrawal, the balloon needs to be contracted to prevent it from scratching the inner wall of the blood vessel. At this point, the pressure pump 110 needs to be depressurized. However, the pressure pump 110 cannot be depressurized directly after pressurization; it can only be depressurized after the first piston rod 112 is separated from the first cylinder 111, i.e., after the pressure pump 110 is unlocked. Therefore, this application adds a quick-release mechanism to the pressure regulating structure 100. The unlocking handle 120 of the quick-release mechanism is located on the first piston rod 112, the first drive assembly 140 is drivenly connected to the first piston rod 112, and the second drive assembly 150 is drivenly connected to the first cylinder 111. When the unlocking handle 120 is unlocked, the first drive assembly 140 can drive the first piston rod 112 to move the unlocking handle 120 radially, causing the external thread 1121 to separate from the internal thread, thereby causing the first piston rod 112 to disengage from the first cylinder 111 in the radial direction, thus unlocking the first cylinder 111 and the first piston rod 112, thereby unlocking the pressure pump 110. At this time, the pressure in the first cylinder 111 is set to zero.

[0049] After the first cylinder 111 is unlocked from the first piston rod 112, the balloon can be contracted by the pressure pump 110. Specifically, the second drive assembly 150 controls the first cylinder 111 to reciprocate relative to the first piston rod 112, allowing the pressure pump 110 to quickly depressurize, thereby causing the balloon to contract. When the balloon contracts to the ideal state, it is easy for the balloon to be withdrawn from the blood vessel. The movement of the first piston rod 112, the first cylinder 111, and the unlocking handle 120 is achieved through the first drive assembly 140 and the second drive assembly 150, which are electrically connected to the remote control console 300. Thus, the operator operates the remote control console 300, which controls the first drive assembly 140 and the second drive assembly 150 to drive the movement of the first piston rod 112, the unlocking handle 120, or the first cylinder 111. Understandably, when the pressure pump 110 is unlocked, the first cylinder 111 and the first piston rod 112 can move, and when the pressure pump 110 is locked, the first cylinder 111 and the first piston rod 112 cannot move.

[0050] The balloon is first inflated and then depressurized during use. The structure and principle of inflating will be mentioned later; here, we will focus on depressurization. When the pressure regulating structure 100 is used to control the balloon depressurization, the remote control console 300 controls the first drive assembly 140 to unlock the unlocking handle 120, so that the external thread 1121 disengages from the internal thread, causing the first piston rod 112 to disengage from the first cylinder 111, thereby unlocking the pressure pump 110. Subsequently, the remote control console 300 controls the second drive assembly 150 to move the first cylinder 111 back and forth relative to the first piston rod 112, so that the pressure pump 110 is quickly depressurized, thereby controlling the balloon contraction and facilitating the balloon's withdrawal from the blood vessel.

[0051] The vascular interventional device 10 of the above embodiment controls the unlocking handle 120 to unlock the first piston rod 112 and the first cylinder 111 through the first drive component 140, ensuring the stability of the unlocking of the pressure pump 110. Then, the second drive component 150 drives the first cylinder 111 to reciprocate relative to the first piston rod 112 to quickly depressurize and control the balloon contraction, thereby ensuring that the balloon contracts to an ideal state so that the balloon can be withdrawn from the blood vessel, ensuring the safety of the interventional operation. Moreover, the pressure regulating structure 100 can be remotely controlled through the remote control console 300, eliminating the need for the operator to enter the operating room and reducing radiation damage to the operator.

[0052] In one embodiment, the first piston rod 112 includes a main rod 1122 and a movable rod 1123. The main rod 1122 has an opening in the axial direction, and the movable rod 1123 is movably disposed in the opening. The movable rod 1123 is connected to the unlocking handle 120 and is driven by the unlocking handle 120 to move radially relative to the main rod 1122. The outer wall of the movable rod 1123 has an external thread. When the unlocking handle 120 is locked, the surface of the movable rod 1123 is coplanar with the surface of the main rod 1122, and the external thread 1121 engages with the internal thread. When the unlocking handle 120 is unlocked, it can drive the movable rod 1123 to move radially into the main rod 1122, and the movable rod 1123 is recessed into the surface of the main rod 1122, and the external thread 1121 separates from the internal thread.

[0053] The unlocking handle 120 has an unlocked position and a locked position. The unlocking handle 120 is in the unlocked position when unlocked and in the locked position when locked. The first drive assembly 140 is connected to the first piston rod 112 and drives the unlocking handle 120 to move. When the pressure pump 110 is locked, the external thread 1121 of the first piston rod 112 engages with the internal thread of the first cylinder 111, at which time the unlocking handle 120 is in the locked position. When the pressure pump 110 is unlocked, the first drive assembly 140 drives the unlocking handle 120 to move and compress it, causing the unlocking handle 120 to move from the locked position to the unlocked position. During the unlocking process, the unlocking handle 120 can drive the external thread 1121 radially away from the internal thread, causing the external thread 1121 to separate from the internal thread. It can be understood that radial direction refers to the direction of the radius of the first cylinder 111, and axial direction refers to the direction of the central axis of the first cylinder 111. The first cylinder 111 and the first piston rod 112 move axially.

[0054] The outer wall of the first piston rod 112 has an axially penetrating opening. The longitudinal cross-section of the first piston rod 112 is a circular notch to form the main rod 1122, and this notch is the opening. The movable rod 1123 is movably disposed in the opening. The outer wall of the movable rod 1123 has an external thread 1121, and the unlocking handle 120 is connected to the movable rod 1123. When the unlocking handle 120 is in the locked position, the movable rod 1123 is located in the opening. At this time, the outer wall of the movable rod 1123 is coplanar with the outer wall of the main rod 1122, forming a complete circular outer wall, and the external thread 1121 engages with the internal thread. When the unlocking handle 120 is unlocked, the squeezing force can drive the movable rod 1123 to move inward toward the inside of the main tube. At this time, the surface of the movable rod 1123 is recessed into the surface of the main rod 1122, causing the external thread 1121 to separate from the internal thread.

[0055] In one embodiment, the first piston rod 112 further includes a reset member, which connects the main rod 1122 and the movable rod 1123. The force of the reset member allows the movable rod 1123 to be positioned in the opening without external force. When unlocking, the unlocking handle 120 overcomes the force exerted by the reset member on the movable rod 1123, causing the movable rod 1123 to move inward. When locking, the unlocking handle 120 resets, and the force of the reset member moves the movable rod 1123 into the opening. Optionally, the reset member is a spring.

[0056] During the unlocking process, the unlocking handle 120 can push the movable rod, and when the unlocking handle 120 is locked, the reset component drives the movable rod to reset. Of course, in other embodiments of this application, the unlocking handle 120 may also be directly or indirectly connected to the movable rod to drive the movable rod to move.

[0057] In one embodiment, the vascular interventional device 10 further includes a mounting bracket 400, an injection structure 200, and a pressure regulating structure 100 disposed on the mounting bracket 400. The mounting bracket 400 serves as the base of the vascular interventional device 10, supporting all components of the vascular interventional device 10 and forming a unified structure. Thus, when the vascular interventional device 10 is used, it can be directly mounted onto the operating table 50. The specific structure of the vascular interventional device 10 will be described in detail later.

[0058] See Figures 2 to 4 In one embodiment, the pressure regulating structure 100 further includes a boosting mechanism 130, which is connected to the first piston rod 112 to drive the pressure pump 110 to increase pressure. The boosting mechanism 130 is disposed on the mounting bracket 400 and is connected to the end of the first piston rod 112 exposed in the first cylinder 111. The boosting mechanism 130 can drive the first piston rod 112 to rotate relative to the first cylinder 111, thereby increasing the pressure of the pressure pump 110. The unlocking handle 120 is fixed to the end of the first piston rod 112 near the boosting mechanism 130.

[0059] The boosting mechanism 130, the first drive assembly 140, and the second drive assembly 150 are electrically connected to the remote control console 300. The remote control console 300 controls the boosting mechanism 130, the first drive assembly 140, and the second drive assembly 150 to perform corresponding actions. Specifically, when the pressure regulating structure 100 is in use, the remote control console 300 controls the boosting mechanism 130 to drive the first piston rod 112 to rotate relative to the first cylinder 111, causing the pressure pump 110 to increase pressure and expand the balloon, thereby allowing the balloon to support the stent at the target position on the blood vessel. Once the stent is in place, the remote control console 300 controls the first drive assembly 140 to drive the unlocking handle 120 to move. The unlocking handle 120 drives the first piston rod 112 to disengage, thus unlocking the pressure pump 110. Subsequently, the remote control console 300 controls the second drive assembly 150 to move the first cylinder 111, causing the first cylinder 111 to move relative to the first piston rod 112, allowing the pressure pump 110 to quickly depressurize and control the balloon contraction.

[0060] Optionally, the vascular interventional device 10 also includes a first control motherboard, which is electrically connected to the first drive assembly 140 and the second drive assembly 150, and also electrically connected to the remote control console 300. The first control motherboard is the controller of the pressure pump 110. The boosting mechanism 130, the first drive assembly 140, and the second drive assembly 150 are electrically connected to the first control motherboard, and are electrically connected to the remote control console 300 through the first control motherboard for convenient signal transmission.

[0061] Optionally, the pressure regulating structure 100 further includes a support mechanism 160, which supports the boosting mechanism 130, the first drive assembly 140, the second drive assembly 150, and the pressure pump 110. Specifically, the support mechanism 160 includes a first bracket 161, which is disposed on the mounting bracket 400 and supports the boosting mechanism 130 and the first drive assembly 140. The first bracket 161 is used to install the boosting mechanism 130 and the first drive assembly 140, ensuring that they are securely fixed to the mounting bracket 400. Optionally, the boosting mechanism 130 is located above the first drive assembly 140. That is, in Figure 2 and Figure 3 In the direction shown, the boosting mechanism 130 and the first drive assembly 140 are stacked vertically to reduce the space occupied.

[0062] Optionally, the second drive assembly 150 is located below the first cylinder 111. For example... Figure 3 As shown, after the first piston rod 112 is connected to the first drive assembly 140, there will be a certain space between the first cylinder 111 and the mounting bracket 400. After the second drive assembly 150 is set in the space between the first cylinder 111 and the mounting bracket 400, it can support and drive the first cylinder 111 while reducing the space occupied and improving the space utilization rate.

[0063] See Figure 2 and Figure 3 In one embodiment, the boosting mechanism 130 includes a third driving member 131 and a second clamping block 132, with the second clamping block 132 connecting the third driving member 131 and the first piston rod 112. The third driving member 131 is the power source for the boosting mechanism 130. The third driving member 131 is fixed to the first bracket 161, and the second clamping block 132 clamps one end of the first piston rod 112 and connects to the output end of the third driving member 131. By clamping the first piston rod 112 with the second clamping block 132, the first piston rod 112 is connected to the third driving member 131. Thus, when the third driving member 131 is working, it can drive the first piston rod 112 to rotate in the first cylinder 111, thereby realizing the boosting operation of the pressure pump 110.

[0064] Optionally, the third driving component 131 can be a stepper motor or a servo electrode, etc. It is worth noting that the structure of the second clamping block 132 is not limited in principle, as long as the second clamping block 132 can clamp the first piston rod 112.

[0065] See Figure 2 and Figure 3In one embodiment, the first drive assembly 140 includes a first drive member 141, a first lead screw member 142, and an unlocking member 143. The unlocking member 143 is movably disposed on the first piston rod 112. The first lead screw member 142 connects the first drive member 141 and the unlocking member 143. When unlocking, the first drive assembly 140 drives the unlocking member 143 to move along the first piston rod 112, so that the unlocking member 143 pushes the unlocking handle 120 and thereby causes the first piston rod 112 to disengage from the first cylinder 111.

[0066] The first driving member 141 is the power source of the first driving assembly 140, and the first lead screw 142 is the transmission component of the first driving assembly 140. The first driving member 141 is fixed to the first bracket 161, and the output end of the first driving member 141 is connected to one end of the first lead screw 142. The moving output end of the first lead screw 142 is connected to the unlocking member 143, which is movably disposed on the first lead screw 142. When the first driving member 141 is working, it drives the first lead screw 142 to output linear motion, which in turn drives the unlocking member 143 to move along the first piston rod 112. In this way, the unlocking member 143 can push the unlocking handle 120, causing the unlocking handle 120 to move from the locked position to the unlocked position, thereby realizing the instantaneous release of pressure from the pressure pump 110. At this time, the pressure pump 110 is unlocked. After the balloon is ejected, the remote control console 300 can control the first drive assembly 140 to reset, that is, control the first drive component 141 to drive the unlocking component 143 to reset, thereby enabling the unlocking handle 120 and the first piston rod 112 to reset.

[0067] Optionally, the first lead screw component 142 includes a first lead screw shaft and a first connecting block. The first connecting block is mounted on the first lead screw shaft, and the first lead screw shaft is connected to the first driving component 141. The first connecting block is connected to the unlocking component 143. Rotation of the first lead screw shaft enables the first connecting block to move synchronously, resulting in linear motion output by the first connecting block. Optionally, the support mechanism 160 further includes two opposing second brackets 162. The two second brackets 162 are spaced apart along the axial direction of the first lead screw shaft, and both ends of the first lead screw shaft are rotatably supported on the second brackets 162. Optionally, the first driving component 141 is a stepper motor or a servo motor.

[0068] Optionally, the unlocking member 143 is flat, i.e., the unlocking member 143 is an unlocking block. Of course, in other embodiments of this application, the unlocking member 143 can also be other structural forms capable of driving the unlocking handle 120 to move. It is worth noting that the structural form of the unlocking handle 120 is not limited in principle, as long as the unlocking handle 120 can drive the first piston rod 112 to disengage from the first cylinder 111 under the drive of the unlocking member 143. Exemplarily, the unlocking handle 120 is handle-shaped. Of course, in other embodiments of this application, the unlocking handle 120 may also be other structural forms capable of driving the first piston rod 112 to move.

[0069] See Figure 3 and Figure 5 In one embodiment, the first drive assembly 140 further includes a first limiting member 144 disposed opposite to the first limiting member 144, the first limiting member 144 being electrically connected to the remote control console 300, and the first lead screw 142 having a first mating member, the first lead screw 142 driving the first mating member to move between the first limiting members 144 and being limited by the first limiting members 144. Figure 5 for Figure 3 A partial schematic diagram of the pressure regulating structure 100 shown.

[0070] The first mating component is a protrusion on the first connecting block of the first lead screw 142. When the first lead screw 142 drives the first connecting block to move, the first connecting block can drive the protrusion on it to move synchronously. The first limiting members 144 are arranged opposite each other along the axial direction of the first lead screw shaft, and the first mating component is located between the two first limiting members 144. When the first lead screw 142 drives the first mating component to move in one direction and abuts against the first limiting member 144, it indicates that the first connecting block has moved to the axial position and cannot continue to move in the direction of the first limiting member 144.

[0071] In other words, the first limiting member 144 limits the movement of the first mating member, thereby restricting the movement distance of the first lead screw 142 and preventing the first connecting block from overtraveling. This ensures that the movement does not deviate from the safe zone, thus guaranteeing the accuracy of the movement of the first lead screw 142 and achieving closed-loop control. Optionally, the first limiting member 144 is a limit switch. Of course, in other embodiments of this application, the first limiting member 144 may also be a proximity switch, photoelectric switch, touch switch, or limit sensor, etc.

[0072] See Figure 2 and Figure 3In one embodiment, the second drive assembly 150 includes a second drive member 151, a second lead screw member 152, and a first clamping block 153. The first clamping block 153 clamps the first cylinder 111, and the second lead screw member 152 connects the second drive member 151 and the second lead screw member 152. The second drive assembly 150 is used to control the contraction of the balloon. The second drive assembly 150 can only operate after the first drive assembly 140 controls the unlocking handle 120 to unlock. That is, the balloon can only be controlled to contract after the pressure pump 110 is depressurized; otherwise, the balloon contraction operation cannot be performed to ensure the safety of the vascular interventional procedure.

[0073] The second drive component 151 is the power source for the second drive assembly 150, and the second lead screw component 152 is the transmission component of the second drive assembly 150. The second drive component 151 is fixed to the mounting bracket 400, and its output end is connected to one end of the second lead screw component 152. The output end of the second lead screw component 152 is connected to a first clamping block 153, which clamps the first cylinder 111 of the pressure pump 110, thereby fixing the first cylinder 111 into the clamping block 153. Thus, after the first drive assembly 140 is unlocked, the second drive assembly 150 begins to operate.

[0074] Specifically, when the second drive unit 151 is working, it drives the second lead screw 152 to move, causing the lead screw 152 to output linear motion. This, in turn, drives the first clamping block 153 to reciprocate the first cylinder 111 relative to the first piston rod 112, causing the pressure pump 110 to control the balloon's contraction. After the balloon is withdrawn, the second drive unit 151 drives the second lead screw 152 to reset the second cylinder 211 for future use.

[0075] The rapid reciprocating translation function of the first cylinder 111 of the pressure pump 110 can only be used after the unlocking handle 120 is unlocked, that is, the balloon can be controlled to contract after the pressure pump 110 is in a depressurized state. Subsequently, the rapid rotation of the second drive component 151 causes the second cylinder 211 to achieve rapid reciprocating translation in the cooperation of the second lead screw shaft and the second connecting block in the second lead screw component 152. The number of reciprocating translations can be set by the system.

[0076] Optionally, the second lead screw component 152 includes a second lead screw shaft and a second connecting block. The second connecting block is disposed on the second lead screw shaft, the second lead screw shaft is connected to the second drive component 151, and the second connecting block is connected to the first clamping block 153. Optionally, the support mechanism 160 further includes a third bracket 163 disposed opposite to it. The third bracket 163 is spaced apart along the axial direction of the second lead screw shaft, and both ends of the second lead screw shaft are rotatably supported on the third bracket 163. Optionally, the second drive component 151 is a servo component.

[0077] It is worth noting that the structural form of the first clamping block 153 is not limited in principle, as long as the first clamping block 153 can clamp the pressure pump 110. Optionally, the first clamping block 153 can be a two-part structure, which can be fastened together by fasteners. Optionally, the ends of the second lead screw 152 and the first lead screw 142 that are close to each other can be supported by the same bracket, that is, one of the second brackets 162 and one of the third brackets 163 can be an integral structure. Optionally, the outer wall of the first cylinder 111 has a concave-convex structure to cooperate with the first clamping block 153 to ensure reliable clamping.

[0078] Optionally, the second drive assembly 150 further includes a gear assembly 155, which is mounted on the third bracket 163. The gear assembly 155 drives the second lead screw shaft of the second drive member 151 and the second lead screw member 152, so that the second lead screw member 152 and the second drive member 151 are arranged vertically, reducing the space occupied and improving space utilization. Optionally, the gear assembly 155 includes two meshing gears, one of which is located at the output end of the second drive member 151, and the other gear is located at the end of the second lead screw shaft.

[0079] See Figure 3 and Figure 5 In one embodiment, the second drive assembly 150 further includes a second limiting member 154 disposed opposite to the remote control console 300. The second limiting member 154 is electrically connected to the remote control console 300. The second lead screw 152 has a second mating member. The second lead screw 152 drives the second mating member to move between the second limiting members 154 and is limited by the second limiting members 154.

[0080] The second mating component is a protrusion on the second connecting block of the second lead screw 152. When the second lead screw 152 drives the second connecting block to move, the second connecting block can drive the protrusion on it to move synchronously. The opposing second limiting members 154 are arranged opposite each other along the axial direction of the second lead screw shaft, and the second mating component is located between the two second limiting members 154. When the second lead screw 152 drives the second mating component to move in one direction and abuts against the second limiting member 154, it indicates that the second connecting block has moved to the axial position and cannot continue to move in the direction of the second limiting member 154.

[0081] In other words, the second limiting member 154 limits the movement of the second mating member, thereby restricting the movement distance of the second lead screw member 152 and preventing the second connecting block from overtraveling. This ensures that the movement does not deviate from the safe zone, thus guaranteeing the accuracy of the movement of the second lead screw member 152. Optionally, the second limiting member 154 is a limit switch. Of course, in other embodiments of this application, the second limiting member 154 may also be a proximity switch, photoelectric switch, touch switch, or limit sensor, etc.

[0082] See Figure 2 and Figure 3 In one embodiment, the pressure regulating structure further includes a communication component disposed in the first cylinder 111 for displaying the pressure value in the first cylinder 111. The communication component is electrically connected to the remote control console 300. The communication component can detect the readings in real time to monitor the pressure of the pressure pump 110 in real time. Optionally, the communication component includes a pressure gauge and a camera. Of course, in other embodiments of this application, the communication component may also be a component capable of detecting pressure values.

[0083] The pressure regulating structure 100 also includes a camera component 170, and the pressure pump 110 also includes a pressure gauge 113. The pressure gauge 113 is disposed in the first cylinder 111 and is used to display the pressure value in the first cylinder 111. The camera component 170 is electrically connected to the remote control console 300 and is disposed parallel to the pressure gauge 113 for capturing the reading of the pressure gauge 113.

[0084] Pressure gauge 113 is located at the end of the first cylinder 111 and is connected to the interior of the first cylinder 111. Pressure gauge 113 displays the pressure value in the first cylinder 111 in real time, thereby enabling real-time reading of the pressure value of the pressure pump 110. When the pressure pump 110 is installed with the imaging component 170, it is necessary to ensure that the pressure gauge 113 and the imaging component 170 are parallel. This allows the imaging component 170 to capture the reading of the pressure gauge 113 in real time, enabling it to monitor the pressure of the pressure pump 110. Optionally, the imaging component 170 can be a camera or similar device. For example, the imaging component 170 can be an autofocus high-definition camera, i.e., an industrial camera. This allows the industrial camera to directly convert image signals into digital signals, making the pressure feedback more stable and reliable.

[0085] After the imaging component 170 captures the reading of the pressure gauge 113, it feeds the reading back to the remote control console 300. The remote control console 300 then determines whether the pressure of the pressure pump 110 meets the requirements. If the pressure gauge 113 shows that the pressure value of the pressure pump 110 is too low, the remote control console 300 controls the pressure boosting mechanism 130 to increase the pressure. If the pressure gauge 113 shows that the pressure value of the pressure pump 110 exceeds the warning value, the pressure boosting stops, and an alarm is issued to ensure the safety of the operation. If the pressure value displayed by the pressure gauge 113 reaches the required level, the remote control console 300 controls the pressure boosting mechanism 130 to stop working, and the other components of the pressure regulating structure 100 begin operation.

[0086] See Figure 2 , Figure 3 and Figure 6 , Figure 6 for Figure 3The diagram shows the workflow of the pressure regulation structure 100. When the balloon is controlled using the pressure regulation structure 100 of this application, the remote control console 300 controls the third drive member 131 of the pressure boosting mechanism 130 to drive the first piston rod 112 to rotate, thereby increasing the pressure of the pressure pump 110. The imaging component 170 collects the reading of the pressure gauge 113 in real time and feeds it back to the remote control console 300. The remote control console 300 determines whether the pressure value after the pressure pump 110 has increased exceeds the warning value. If it exceeds the warning value, the pressure boosting operation is stopped and an alarm is issued to alert the operator. If it does not exceed the warning value, it determines whether the balloon pressure has reached the predetermined value. If it has not reached the predetermined value, the pressure boosting mechanism 130 is controlled to continue the pressure boosting operation. If the predetermined value is reached, the pressure boosting mechanism 130 is controlled to stop the pressure boosting. At this time, the pressure of the pressure pump 110 can drive the balloon to expand, and the balloon can then support the stent at the target position of the blood vessel. Then, the remote control console 300 controls the first drive member 141 of the first drive assembly 140 to drive the first lead screw member 142 to move the unlocking handle 120, causing the external thread 1121 of the first piston rod 112 to disengage from the internal thread of the first cylinder 111, thereby unlocking the first piston rod 112 relative to the first cylinder 111, and thus unlocking the pressure pump 110. Subsequently, the remote control console 300 controls the second drive member 151 of the second drive assembly 150 to drive the second lead screw member 152 to move the first cylinder 111 back and forth relative to the first piston rod 112 multiple times, causing the pressure pump 110 to depressurize rapidly, thereby controlling the balloon to contract until the balloon contracts to the desired shape. At this point, the balloon can be withdrawn from the blood vessel.

[0087] The pressure pump 110's pressurization and depressurization are achieved through the cooperation of the first drive member 141 and the second drive member 151. Depressurization occurs in different ways depending on the stage of the vascular interventional procedure. During pressurization, depressurization can be achieved by reversing the rotation of the first drive member 141. During balloon withdrawal from the patient's body, the second drive member 151 must first be rotated to unlock the release handle 120, causing the external thread 1121 of the first piston rod 112 of the pressure pump 110 to disengage from the internal thread of the first cylinder 111, thus releasing pressure and reducing the pressure in the pressure pump 110 to zero. Simultaneously, when the pressure pump 110 needs to draw saline solution, this is achieved by performing a depressurization step, but the second drive member 151 does not need to operate at this time.

[0088] Furthermore, whether the pressure value exceeds the warning threshold is monitored and fed back in real time through a combination of algorithms from the imaging component 170 and the remote control console 300. Since the balloon needs to be in the most ideal state of contraction when it is withdrawn from the patient's body (otherwise it will damage the inner wall of the blood vessels), the first cylinder 111 usually needs to move back and forth 3-4 times relative to the first piston rod 112, that is, it needs to repeatedly and rapidly increase and decrease the pressure 3-4 times to obtain the balloon in the ideal surgical state.

[0089] See Figure 2 and Figure 7 In one embodiment, the vascular interventional device 10 further includes an injection structure 200, which includes a syringe 210, a connecting mechanism 230, and an injection driving mechanism 220. The syringe 210 includes a second barrel 211 and a second piston rod 212. The second piston rod 212 is telescopically disposed on the second barrel 211. The second barrel 211 is connected to the connecting mechanism 230, and the connecting mechanism 230 is externally connected to an infusion tube. The injection driving mechanism 220 is electrically connected to a remote control console 300. The remote control console 300 controls the injection driving mechanism 220 to drive the second piston rod 212 to move, so that the connecting mechanism 230 can perform the injection operation. Figure 7 for Figure 2 A schematic diagram of the injection structure 200 in the vascular interventional device 10 shown.

[0090] The injection structure 200 is used to inject fluids during vascular interventional procedures. The injection structure 200 delivers medications or other fluids into the patient's body through an interventional catheter to ensure the safety of the vascular interventional procedure. Specifically, the second barrel 211 of the syringe 210 is fixedly installed, and the second piston rod 212 is movably installed within the second barrel 211. When the second piston rod 212 moves relative to the second barrel 211, it can achieve the purpose of injection and aspiration.

[0091] One end of the second cylinder 211 is connected to one end of the connecting mechanism 230, and the other end of the connecting mechanism 230 is connected to an interventional catheter, which is connected to the patient's blood vessel. That is, the connecting mechanism 230 is connected to the syringe 210, and through the cooperation of the syringe 210 and the connecting mechanism 230, liquid aspiration and injection operations are achieved. One end of the second piston rod 212 is connected to the injection drive mechanism 220, and the movement of the injection drive mechanism 220 is controlled by the remote control console 300. Thus, when the remote control console 300 controls the operation of the injection structure 200, the remote control console 300 controls the movement of the injection drive mechanism 220, which in turn controls the movement of the second piston rod 212, causing the second piston rod 212 to move relative to the second cylinder 211, thereby enabling the connecting mechanism 230 to perform liquid aspiration and injection operations.

[0092] Furthermore, the injection structure 200 is mounted on the mounting bracket 400, which supports the injection structure 200. The mounting bracket 400 also supports the pressure regulating structure 100 mentioned above. Thus, the injection structure 200 and the pressure regulating structure 100 can be integrated into one unit, facilitating operation by the operator. Optionally, the vascular interventional device 10 also includes a second control motherboard, which is electrically connected to the injection drive mechanism 220 and also electrically connected to the remote control console 300. The second control motherboard is the controller of the pressure pump 110. The injection drive mechanism 220 is electrically connected to the second control motherboard, and the second control motherboard is electrically connected to the remote control console 300 for convenient signal transmission.

[0093] See Figure 7 In one embodiment, the injection drive mechanism 220 includes a fourth drive member 221, a third lead screw member 222, and a connector 223. The connector 223 is disposed at the end of the second piston rod 212, and the third lead screw member 222 connects the connector 223 and the fourth drive member 221.

[0094] The fourth driving component 221 is the power source for the injection driving mechanism 220. The third lead screw component 222 is the transmission component of the injection driving mechanism 220. The fourth driving component 221 is fixed to the mounting bracket 400. The output end of the fourth driving component 221 is connected to one end of the third lead screw component 222. The output end of the third lead screw component 222 is connected to the connecting component 223, and then the connecting component 223 is connected to the end of the second piston rod 212. When the fourth driving component 221 is working, it drives the third lead screw component 222 to output linear motion, which in turn drives the connecting component 223 to move the second piston rod 212.

[0095] Thus, the second piston rod 212 can move relative to the second cylinder 211 to achieve liquid aspiration and injection operations. When the connecting member 223 pulls the second piston rod 212 outwards towards the second cylinder 211, the syringe 210 performs aspiration. When the connecting member 223 pushes the second piston rod 212 inwards towards the second cylinder 211, the syringe 210 performs aspiration. Optionally, the fourth driving member 221 is a stepper. The injection and aspiration of the syringe 210 are controlled by the rotation of the fourth driving member 221 to advance (push, inject) and retract (pull, aspirate) the second piston rod 212. The speed of injection and aspiration can be controlled by controlling the rotation of the stepper. Generally, the slower the aspiration speed, the less air is generated in the second cylinder 211.

[0096] Optionally, the third lead screw component 222 includes a third lead screw shaft and a third connecting block. The third connecting block is disposed on the third lead screw shaft. The third lead screw shaft is connected to the third driving component 131, and the third connecting block is connected to the connecting component 223. Rotation of the third lead screw shaft can drive the third connecting block to move synchronously, causing the third connecting block to output linear motion. Optionally, the injection drive structure also includes a fourth bracket disposed opposite to each other. The two fourth brackets are spaced apart along the axial direction of the third lead screw shaft, and the two ends of the third lead screw shaft are rotatably supported on the fourth brackets.

[0097] It is worth noting that the structural form of the connector 223 is not limited in principle, as long as the connector 223 can connect to the end of the second piston rod 212 to ensure that the third lead screw 222 can drive the second piston rod 212 to move synchronously. In this embodiment, as shown... Figure 7 As shown, the connector 223 is arranged in a ring and is sleeved on the third connecting block. The connector 223 is connected to the second piston rod 212. This ensures the reliability of the connection between the second piston rod 212 and the third lead screw 222.

[0098] See Figure 7 and Figure 8 In one embodiment, the injection drive mechanism 220 further includes a third limiting member 224 disposed opposite to it. The third limiting member 224 is electrically connected to the remote control console 300. The third lead screw member 222 has a third mating member. The third lead screw member 222 drives the third mating member to move between the third limiting members 224 and is limited by the third limiting members 224. Figure 8 for Figure 7 A partial schematic diagram of the injection structure 200 shown.

[0099] The third mating component is a protrusion on the third connecting block of the third lead screw component 222. When the third lead screw component 222 drives the third connecting block to move, the third connecting block can drive the protrusion on it to move synchronously. The oppositely arranged third limiting components 224 are arranged opposite each other along the axial direction of the third lead screw shaft, and the third mating component is located between the two third limiting components 224. When the third lead screw component 222 drives the third mating component to move in one direction and abuts against the third limiting component 224, it indicates that the axial movement of the third connecting block has reached its position and it cannot continue to move in the direction of the third limiting component 224.

[0100] In other words, the third limiting member 224 limits the movement of the third mating member, thereby restricting the movement distance of the third lead screw 222 and preventing the third connecting block from overtraveling. This ensures that the movement does not deviate from the safe zone, thus guaranteeing the accuracy of the movement of the third lead screw 222. Optionally, the third limiting member 224 is a limit switch. Of course, in other embodiments of this application, the third limiting member 224 may also be a proximity switch, photoelectric switch, touch switch, or limit sensor, etc.

[0101] Optionally, the injection drive mechanism 220 further includes a guide assembly 225, which connects the mounting bracket 400 and the third connecting block to guide the movement of the third connecting block. By guiding the movement of the third connecting block through the guide assembly 225, the accurate trajectory of the third connecting block is ensured, thereby guaranteeing that the third connecting block can accurately drive the second piston rod 212. Optionally, the guide assembly 225 includes a guide rail and a guide slider. The guide rail is disposed on the mounting bracket 400, and the guide slider is connected to the third connecting block, slidably disposed on the guide rail. When the third lead screw drives the third connecting block to move, the third connecting block drives the guide slider to move along the guide rail to achieve the guiding purpose.

[0102] See Figure 7 In one embodiment, the injection structure 200 further includes a fixing mechanism 240, which includes a first fixing component 241 and a second fixing component 242. The first fixing component 241 and the second fixing component 242 are spaced apart along the axial direction of the second cylinder 211 and are used to fix the second cylinder 211.

[0103] The fixing mechanism 240 is disposed on the mounting bracket 400, and the second cylinder 211 is fixed to the fixing mechanism 240, thereby reliably fixing the second cylinder 211 to the mounting bracket 400. Furthermore, the fourth driving component 221 can be fixed to the mounting bracket 400 or mounted to the fixing mechanism 240, and supported and fixed by the fixing mechanism 240. Figure 7 With the indicated direction as a reference, the first fixing component 241 fixes the second cylinder 211 at the front end of the second cylinder 211, and the second fixing component 242 fixes the second cylinder 211 at the rear end of the second cylinder 211. The cooperation between the first fixing component 241 and the second fixing component 242 achieves reliable fixation of the second cylinder 211, preventing the position of the second cylinder 211 from shifting when the syringe 210 is working.

[0104] It is worth noting that the structural forms of the first fixing component 241 and the second fixing component 242 are not limited in principle, as long as they can reliably fix the second cylinder 211. Optionally, the first fixing component 241 can be a combination of a fixing bracket and a clamping block 434, and the second fixing component 242 can be two positioning posts that clamp the second cylinder 211. Of course, in other embodiments of this application, the first fixing component 241 and the second fixing component 242 can also be other structural forms that can achieve fixation.

[0105] See Figure 2 and Figure 7In one embodiment, the connecting mechanism 230 includes a clamping block 231, a three-way valve 232, a fifth driving member 233, and a sixth driving member 234. The three-way valve 232 is positioned by the clamping block 231. The three-way valve 232 includes a first valve 2321, a second valve 2322, and a third valve 2323. The first valve 2321 is used to connect to a blood pressure monitor, the second valve 2322 is used to deliver heparin, and the third valve 2323 is used to deliver contrast agent. The fifth driving member 233 is connected to the second valve 2322 and is used to control the opening and closing of the second valve 2322. The sixth driving member 234 is connected to the third valve 2323 and is used to control the opening and closing of the third valve 2323.

[0106] The clamping block 231 is used to fix the three-way valve 232 and prevent its position from shifting. The clamping block 231 is mounted on the mounting bracket 400 and has a notch for installing the three-way valve 232 and a channel for the arrangement of the pipes in the three-way valve 232, so that the three-way valve 232 can be embedded in the clamping block 231. Before clamping, the three-way valve 232 is first tightened to the second barrel 211 of the syringe 210, and then simultaneously positioned and clamped. That is, the second barrel 211 is clamped and positioned by the first fixing component 241 and the second fixing component 242, and the three-way valve 232 is clamped and positioned by the clamping block 231.

[0107] During clamping, it is necessary to ensure that the valve position of the three-way valve 232 is in the initial default position; otherwise, manual adjustment is required to facilitate the insertion of the clamping block 231. It is worth noting that the notch and channel of the clamping block 231 are designed according to the structural form of the three-way valve 232, which will not be elaborated here.

[0108] To better describe the injection structure 200, the three valves of the three-way valve 232 are defined as the first valve 2321, the second valve 2322, and the third valve 2323. The first valve 2321 is connected to a blood pressure monitor to detect blood pressure in real time during the procedure. The second valve 2322 delivers heparin, and the third valve 2323 delivers contrast agent. A fifth actuator 233 is connected to the second valve 2322 to control its opening and closing. When the fifth actuator 233 drives the second valve 2322 to connect with the second barrel 211 of the syringe 210, the second valve 2322 can draw or inject heparin. A sixth actuator 234 is connected to the third valve 2323 to control its opening and closing. When the sixth actuator 234 drives the third valve 2323 to connect with the second barrel 211 of the syringe 210, the third valve 2323 can draw or inject contrast agent.

[0109] The aspiration and injection of various injection solutions depend on the status of each valve in the three-way valve 232, and each valve has three position states. The injection operation at the corresponding stage is achieved by controlling the position of each valve. Understandably, during vascular interventional procedures, it is necessary to monitor the patient's blood pressure in real time. Therefore, the first valve 2321 is always in the open state to maintain real-time connection with the blood pressure monitor, ensuring that the monitor can monitor the patient's blood pressure and guaranteeing the safety of the vascular interventional procedure. Therefore, the first valve 2321 does not operate during the vascular interventional procedure and does not require a drive mechanism; it only needs to be turned to the open state before the procedure. Optionally, the fifth drive mechanism 233 and the sixth drive mechanism 234 are servo components.

[0110] Optionally, the connecting mechanism 230 further includes two actuating blocks, one of which is disposed between the second valve 2322 and the fifth driving member 233, and the other of which is disposed between the third valve 2323 and the sixth driving member 234. When the fifth driving member 233 is working, it drives the actuating block to move, thereby actuating the second valve 2322 to adjust its on / off state. The principle by which the sixth driving member 234 controls the third valve 2323 is essentially the same and will not be described further here.

[0111] Optionally, the connecting mechanism 230 further includes a connecting bracket, which is disposed in the mounting bracket 400 and used to support the clamping block 231. After the clamping block 231 is supported by the connecting bracket, a certain space exists between the clamping block 231 and the mounting bracket 400, facilitating the arrangement of the fifth driving component 233 and the sixth driving component 234, as well as the installation of other components. Optionally, the connecting bracket and the clamping block 231 can be an integral structure or separate components.

[0112] See Figure 7 and Figure 9 , Figure 9 for Figure 7 The diagram shows the workflow of the injection structure 200 during injection. Before injection using the injection structure 200 of this application, the in-situ signal of the three-way valve 232 is detected to ensure that each valve of the three-way valve 232 is in a normal position. The injection structure achieves its corresponding function through the cooperation of the three valves. If a valve malfunction causes blockage, the parameters of the fourth actuator 221 can be used to determine whether the injection or aspiration process is normal, such as a significant change in the push-pull force applied by the fourth actuator 221 to the second piston rod 212. After the in-situ signal detection of the three-way valve 232 is completed, the remote control console 300 controls the syringe 210 to perform the injection operation.

[0113] When the remote control console 300 controls the injection structure 200 to operate, the remote control console 300 determines whether the third valve 2323 of the three-way valve 232 has switched to the aspiration path. If not, the remote control console 300 controls the sixth drive member 234 to operate, which in turn controls the third valve 2323 of the three-way valve 232 to switch to the aspiration path. If yes, the remote control console 300 controls the fourth drive member 221 of the injection drive mechanism 220 to pull the second piston rod 212 of the syringe 210 to draw up the contrast agent via the third lead screw member 222. The remote control console 300 determines whether the amount of contrast agent drawn into the syringe 210 is sufficient based on the movement of the second piston rod 212. If not, the remote control console 300 continues to control the fourth drive member 221 to pull the second piston rod 212. If yes, that is, the amount of contrast agent drawn has reached the preset value, the remote control console 300 controls the fourth drive member 221 to stop moving.

[0114] Subsequently, the remote control console 300 determines whether the third valve 2323 of the three-way valve 232 has switched to the injection pathway. If not, the remote control console 300 controls the sixth actuator 234 to switch the third valve 2323 to the injection pathway. If yes, the remote control console 300 controls the fourth actuator 221 to push the second piston rod 212 via the third lead screw 222 to inject the contrast agent. Then, the remote control console 300 determines whether heparin needs to be injected; otherwise, the remote control console 300 remains in a pending state, and the three-way valve 232 does not operate. If yes, the remote control console 300 controls the sixth actuator 234 to switch the third valve 2323 to the injection pathway, and the fifth actuator 233 controls the second valve 2322 to switch to the aspiration pathway.

[0115] The remote control console 300 controls the fourth drive unit 221 to pull the second piston rod 212 of the syringe 210 to draw heparin via the third lead screw 222. The remote control console 300 determines whether the amount of heparin drawn into the syringe 210 is sufficient based on the movement of the second piston rod 212. If not, the remote control console 300 continues to control the fourth drive unit 221 to pull the second piston rod 212. If so, that is, the amount of heparin drawn has reached a preset value, the remote control console 300 stops the movement of the fourth drive unit 221. The remote control console 300 then controls the fifth drive unit 233 to switch the second valve 2322 to the injection channel, and the remote control console 300 controls the fourth drive unit 221 to push the second piston rod 212 via the third lead screw 222 to inject heparin.

[0116] See Figure 2 , Figure 10 and Figure 11 In one embodiment, the mounting bracket 400 includes a support side plate 420 and a support top plate 410 disposed opposite to each other. The support side plate 420 and the support top plate 410 are connected. The support top plate 410 is inclined relative to the horizontal plane, and the inclination angle of the support top plate 410 is in the range of 10° to 20°. Figure 10 for Figure 2 The side view of the vascular interventional device 10 shown is shown. Figure 11 for Figure 2 A partial schematic diagram of the vascular interventional device 10 as shown from the bottom.

[0117] Support side plates 420 are arranged opposite each other on both sides, and the top of the two support side plates 420 supports the top plate 410. That is, the two support side plates 420 support the top plate 410 to form a support structure to support the various components of the vascular intervention device 10. Moreover, as Figure 2 As shown, the support top plate 410 is inclined relative to the horizontal plane. Thus, after the syringe 210 and pressure pump 110 are installed on the support top plate 410, they will also form a certain angle with the horizontal plane. That is, the syringe 210 and pressure pump 110 are arranged parallel to the support top plate 410, and because the support top plate 410 has a certain angle with the horizontal plane, the syringe 210 and pressure pump 110 will also have a certain angle with the horizontal plane.

[0118] Understandably, a certain amount of air may be present in the pressure pump 110 and syringe 210 during actual use. With the aforementioned tilted design, the air can automatically rise to the top space of the pressure pump 110 and syringe 210, preventing air from being injected into the body and ensuring the safety of the surgical procedure. Figure 9 As shown, Figure 9 This illustrates the situation where air appears in the pressure pump 110.

[0119] Optionally, the angle between the supporting top plate 410 and the horizontal plane ranges from 10° to 20°. Within this angle range, the supporting top plate 410 ensures a certain distance between the air and the outlet ends of the pressure pump 110 and the syringe 210. For example, the angle between the supporting top plate 410 and the horizontal plane is 12°. That is, the supporting top plate 410 is designed with a 12° inclination. Optionally, the supporting top plate 410 and the supporting side plate 420 have a perforated design. This allows for reliable support while reducing the overall weight.

[0120] like Figure 1 As shown, the installation position of the vascular interventional device 10 of this application is not limited in principle. It can be placed directly on the operating table 50, or it can be installed on the side of the operating table 50 by side mounting. When the vascular interventional device 10 is placed horizontally, it can be placed directly on the operating table 50 with a certain distance between it and the patient, without the need for fixation.

[0121] Under normal circumstances, the vascular interventional device 10 of this application is installed directly on the operating table 50. When the patient is large and there is no extra space on the operating table 50 to place the device, the vascular interventional device 10 can be mounted on its side. When the vascular interventional device 10 is mounted on its side, the clamping mechanism 430 is required to clamp and fix the vascular interventional device 10 to the operating table 50 to prevent the position of the vascular interventional device 10 from shifting and to ensure its reliable fixation.

[0122] See Figure 2 , Figure 10 and Figure 11 In one embodiment, the mounting bracket 400 further includes a clamping mechanism 430, which is disposed on the supporting side plate 420 and detachably clamped to the side of the operating table 50. The clamping mechanism 430 is disposed at the bottom of the supporting top plate 410 and extends from the supporting side plate 420. This allows the operator to manipulate the clamping mechanism 430 to clamp the side of the operating table 50, ensuring that the vascular intervention device 10 is reliably fixed.

[0123] See Figure 2 , Figure 10 and Figure 11 In one embodiment, the clamping mechanism 430 includes a support base 431, an adjustment knob 432, a fourth lead screw 433, and two clamping blocks 434. The two clamping blocks 434 are disposed opposite to each other on the support base 431. The adjustment knob 432 is disposed on the fourth lead screw 433. The fourth lead screw 433 is connected to the clamping blocks 434 and drives at least one clamping block 434 to move, so that the two clamping blocks 434 clamp or release.

[0124] A support base 431 is disposed between the top support plate 410 and the side support plate 420. The support base 431 supports the various components of the clamping mechanism 430, thus fixing the clamping mechanism 430 to the top support plate 410 and the side support plate 420. An adjustment knob 432 is located on the outside of the side support plate 420. One end of the fourth lead screw 433 passes through the support base 431 and connects to the adjustment knob 432. The output end of the fourth lead screw 433 is connected to the clamping block 434. Thus, when the adjustment knob 432 is operated to move the fourth lead screw 433, the fourth lead screw 433 can move the clamping block 434, thereby enabling the two clamping blocks 434 to clamp or release.

[0125] In this embodiment, there are two adjusting knobs 432 and two corresponding fourth lead screws 433. Each adjusting knob 432 is connected to a clamping block 434 via a fourth lead screw 433. Thus, when the operator operates the two adjusting knobs 432, the two adjusting knobs 432 drive the corresponding clamping blocks 434 to move through the corresponding fourth lead screws 433, causing the two clamping blocks 434 to move closer to or further away from each other, thereby achieving the clamping or releasing function. Of course, in other embodiments of this application, the number of adjusting knobs 432 and fourth lead screws 433 can also be one. In this case, the adjusting knob 432 drives the fourth lead screw 433 to drive the corresponding clamping block 434 closer to or further away from the other clamping block 434, also achieving the clamping or releasing function.

[0126] Optionally, the clamping mechanism 430 further includes a guide rail, and the clamping block 434 has a guide hole, through which the clamping block 434 is mounted into the guide rail. When the fourth lead screw 433 drives the clamping block 434 to move, the movement of the clamping block 434 is guided by the cooperation between the guide rail and the guide hole, ensuring the accuracy of the movement trajectory of the clamping block 434. The fourth lead screw 433 includes a fourth lead screw shaft and a fourth connecting block, the fourth connecting block being movably mounted on the fourth lead screw shaft. Optionally, the fourth lead screw shaft is a trapezoidal lead screw to ensure the reliability of clamping and prevent loosening.

[0127] See Figure 11 In one embodiment, the clamping block 434 has a clamping ramp 4341, the inclination angle of which ranges from 10° to 20°. The clamping jaws of the clamping block 434 have inclined ramps. When the two clamping blocks 434 clamp the sides of the operating table 50, the entire vascular interventional device 10 has an inclined, rising structure. This design of the clamping ramp 4341 also ensures that air in the syringe 210 and pressure pump 110 floats upwards and is not delivered into the patient's body.

[0128] In one embodiment, the clamping mechanism 430 further includes a torque sensor 440, which is disposed on the adjusting knob 432 and is used to detect the tightening force output by the adjusting knob 432. The torque sensor 440 is connected to the adjusting knob 432, and can detect the tightening force of the adjusting knob 432 to ensure that the vascular intervention device 10 is reliably fixed during side mounting, thereby ensuring the reliability of side mounting. Optionally, the torque sensor 440 is a dynamic torque sensor, which only allows other functions to be enabled when the torque of the fourth lead screw 433 reaches a preset value. Of course, in other embodiments of this application, the torque sensor 440 may also be a pressure sensor or other types of sensors.

[0129] See Figure 1 and Figure 12In one embodiment, the remote control console 300 has a main control board, a display screen 310, multiple function buttons 320, and multiple rocker arms 330. The main control board is electrically connected to the first drive component 140, the second drive component 150, and the injection drive mechanism 220, and is also electrically connected to the display screen 310, the function buttons 320, and the rocker arms 330. The display screen 310 is used to limit remote interactive information, and the function buttons 320 and the rocker arms 330 are used to control the first drive component 140, the second drive component 150, and the injection drive mechanism 220. Figure 12 for Figure 1 A schematic diagram of the remote control console 300 in the vascular interventional device 10 shown.

[0130] The operator uses the rocker arm 330 and function buttons 320 of the remote control console 300 to control the functions of the pressure pump 110 and syringe 210, enabling them to perform corresponding operations. In this embodiment, there are three function buttons 320 and three rocker arms 330. The three function buttons 320 correspond to a complex set of actions; for example, the first function button 320 corresponds to the pressure release and unlocking operation of the pressure pump 110, the second function button 320 corresponds to the rapid reciprocating movement of the pressure pump 110 after pressure release and unlocking, and the third function button 320 corresponds to a one-key reset function. The rocker arm 330 can rotate and swing back and forth to achieve rotational control of components, thereby realizing simple functional control, such as pressurizing and depressurizing the pressure pump 110 and injecting and aspirating liquid with the syringe 210. Of course, in other embodiments of this application, the number of function buttons 320 and rocker arms 330 may be greater.

[0131] The display screen 310 is used to display visual data related to the vascular interventional device 10 during vascular interventional procedures. For example... Figure 12 As shown, Figure 13 The remote control console 300's display screen 310 provides a prompt for remote control interaction. Displaying remote interaction data on the screen 310 facilitates the operator's monitoring of various parameters during the vascular intervention process, ensuring the safety of the procedure. Furthermore, while operating the remote control console 300, the operator can also access various parameters and statuses of the invention via the touchscreen display screen 310, making the surgical process more controllable. The use of a status indicator bar and speaker provides clear alarm prompts to the operator in case of abnormalities, ensuring the safety and reliability of the surgical process.

[0132] The remote control console 300 is electrically connected to the host computer (industrial control computer) to achieve signal transmission. The main control board of the remote control console 300 establishes communication with the industrial control computer to transmit control command signals (bidirectional). The industrial control computer and each electrode in the vascular intervention device 10 interact with each other (bidirectional) through a router. When each component driver of the vascular intervention device 10 receives the corresponding control command, the control component performs the corresponding action. Since the servo component is a closed-loop control, its interaction with the component driver is bidirectional, while the stepper component is an open-loop control, so its interaction with the component driver is only unidirectional. As a limit component, it can communicate with the corresponding component. When the limit component is triggered, the remote control console 300 obtains the signal and the control component executes the corresponding action.

[0133] The vascular interventional device 10 disclosed herein is a small, remotely driven integrated device that completely replicates the manual operation of the contrast agent injector 210 and pressure pump 110 during vascular interventional procedures. Integrating the injector 210 and pressure pump 110 into one unit facilitates both use and storage. Furthermore, the injection speed and dosage of the contrast agent are controllable, and the injection solution can be switched at any time via the three-way valve 232. The pressure boosting efficiency of the pressure pump 110 is higher and more stable than manual operation. The device can be installed horizontally or sideways, offering flexibility in application scenarios. The tilting design allows air within the pressure pump 110 and injector 210 to automatically rise and prevent injection into the body. The pressure value of the pressure pump 110 can communicate with the remote control console 300, forming a complete closed-loop control system.

[0134] When using the vascular interventional device 10, the operator can operate it remotely outside the operating room or via a control panel behind a protective screen inside the operating room, avoiding radiation risks. Furthermore, the fourth drive component 221 drives the third lead screw component 222 to pull or push the piston rod, precisely quantifying the injection of contrast agent and heparin. The first drive component 141, second drive component 151, and third drive component 131 control the pressure pump 110, preventing hand fatigue caused by operator operation of the pressure pump 110, improving pressurization efficiency, and precisely quantifying the relationship between advancement speed and pressure value.

[0135] In the vascular interventional device 10 of this application, apart from the pressure pump 110, syringe 210, and three-way valve 232, which are consumables, no other consumables are required. All other components are reusable, which significantly reduces patient costs, simplifies operation, improves training efficiency, and facilitates operator use. Furthermore, the vascular interventional device 10 is a remotely automated control device. To monitor the pressure value of the pressure pump 110 in real time, the device automatically analyzes the pressure value image of the pressure gauge 113 acquired by the imaging component 170 and converts it into a digital signal, which is then fed back to the remote control console 300, achieving a safe and stable closed-loop system. To achieve closed-loop control of the device, each lead screw component is limited by the polarity of its corresponding limit component, preventing damage to the device and harm to the patient due to exceeding its travel range.

[0136] like Figure 6 As shown, when the balloon is controlled using the pressure regulating structure 100 of this application, the remote control console 300 controls the third drive member 131 of the pressure boosting mechanism 130 to drive the first piston rod 112 to rotate, thereby increasing the pressure of the pressure pump 110. The imaging component 170 collects the reading of the pressure gauge 113 in real time and feeds it back to the remote control console 300. The remote control console 300 determines whether the pressure value after the pressure pump 110 has increased exceeds the warning value. If it exceeds the warning value, the pressure boosting operation is stopped and an alarm is issued to alert the operator. If it does not exceed the warning value, it determines whether the balloon pressure has reached the predetermined value. If it has not reached the predetermined value, the pressure boosting mechanism 130 is controlled to continue the pressure boosting operation. If it reaches the predetermined value, the pressure boosting mechanism 130 is controlled to stop the pressure boosting. At this time, the pressure of the pressure pump 110 can drive the balloon to expand, and the balloon can then support the stent at the target position of the blood vessel. Then, the remote control console 300 controls the first drive member 141 of the first drive assembly 140 to drive the first lead screw member 142 to move the unlocking handle 120, causing the external thread 1121 of the first piston rod 112 to disengage from the internal thread of the first cylinder 111, thereby unlocking the first piston rod 112 relative to the first cylinder 111, and thus unlocking the pressure pump 110. Subsequently, the remote control console 300 controls the second drive member 151 of the second drive assembly 150 to drive the second lead screw member 152 to move the first cylinder 111 back and forth relative to the first piston rod 112 multiple times, causing the pressure pump 110 to depressurize rapidly, thereby controlling the balloon to contract until the balloon contracts to the desired shape. At this point, the balloon can be withdrawn from the blood vessel.

[0137] like Figure 9As shown, when the remote control console 300 controls the injection structure 200 to operate, the remote control console 300 determines whether the third valve 2323 of the three-way valve 232 has switched to the aspiration path. If not, the remote control console 300 controls the sixth drive member 234 to operate, and the sixth drive member 234 then controls the third valve 2323 of the three-way valve 232 to switch to the aspiration path. If yes, the remote control console 300 controls the fourth drive member 221 of the injection drive mechanism 220 to pull the second piston rod 212 of the syringe 210 to draw up the contrast agent through the third lead screw member 222. The remote control console 300 determines whether the amount of contrast agent drawn into the syringe 210 is sufficient based on the movement of the second piston rod 212. If not, the remote control console 300 continues to control the fourth drive member 221 to pull the second piston rod 212. If yes, that is, the amount of contrast agent drawn has reached the preset value, the remote control console 300 controls the fourth drive member 221 to stop moving.

[0138] Subsequently, the remote control console 300 determines whether the third valve 2323 of the three-way valve 232 has switched to the injection pathway. If not, the remote control console 300 controls the sixth actuator 234 to switch the third valve 2323 to the injection pathway. If yes, the remote control console 300 controls the fourth actuator 221 to push the second piston rod 212 via the third lead screw 222 to inject the contrast agent. Then, the remote control console 300 determines whether heparin needs to be injected; otherwise, the remote control console 300 remains in a pending state, and the three-way valve 232 does not operate. If yes, the remote control console 300 controls the sixth actuator 234 to switch the third valve 2323 to the injection pathway, and the fifth actuator 233 controls the second valve 2322 to switch to the aspiration pathway.

[0139] The remote control console 300 controls the fourth drive unit 221 to pull the second piston rod 212 of the syringe 210 to draw heparin via the third lead screw 222. The remote control console 300 determines whether the amount of heparin drawn into the syringe 210 is sufficient based on the movement of the second piston rod 212. If not, the remote control console 300 continues to control the fourth drive unit 221 to pull the second piston rod 212. If so, that is, the amount of heparin drawn has reached a preset value, the remote control console 300 stops the movement of the fourth drive unit 221. The remote control console 300 then controls the fifth drive unit 233 to switch the second valve 2322 to the injection channel, and the remote control console 300 controls the fourth drive unit 221 to push the second piston rod 212 via the third lead screw 222 to inject heparin.

[0140] See Figure 1This application also provides an interventional surgical system, including an interventional surgical robot 60, an operating table 50, and a vascular interventional device 10 as described in any of the above embodiments. The interventional surgical robot 60 is located on the side of the operating table 50 and is used to perform interventional operations. The vascular interventional device 10 is placed on or clamped to the side of the operating table 50. When the interventional surgical system of this application uses the vascular interventional device 10 of the above embodiments, it can achieve controllable injection speed and dosage of contrast agent while avoiding radiation. Furthermore, the injection solution can be switched at any time through the three-way valve 232, and the pressure boosting efficiency of the pressure pump 110 is higher and more stable than manual operation.

[0141] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0142] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
