Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an interventional surgery catheter delivery device. Background Art

[0002] Vascular interventional surgery is a surgical procedure in which interventional doctors operate puncture needles, catheters, guidewires, balloons, stents and other interventional devices under the guidance of medical imaging equipment, and deliver the designated devices along the human blood vessels to the corresponding lesion site after percutaneous puncture for treatment. As a minimally invasive treatment method, vascular interventional surgery has been widely used in the interventional treatment of cardiovascular diseases, cerebrovascular diseases, peripheral vascular diseases and tumors.

[0003] In vascular intervention surgery, the doctor first operates the vascular sheath into the coronary artery. The external part of the vascular sheath is retained outside the body. The catheter guide wire passes through the vascular sheath into a part of the human coronary artery, and the catheter follows the guide wire through the vascular sheath into the human coronary artery. The guide wire goes in a part first, and the catheter follows a part, and the combination is advanced until the catheter enters the coronary artery orifice and remains in place, and the guide wire exits the catheter and retreats outside the body. In this way, the work of the catheter entering the human coronary artery orifice is successfully completed, so that subsequent angiography and interventional surgery lesion treatment can be carried out.

[0004] In the current surgical model, interventional doctors need to wear lead suits weighing 20 to 30 kilograms and stand beside the operating table for a long time to operate interventional instruments such as catheters and guidewires; however, the lead suit cannot completely block X-ray radiation, and the arms and head are directly exposed to X-rays. Interventional doctors work in an X-ray radiation environment for many years, which can easily lead to high incidence of occupational diseases such as cataracts, spinal curvature, and brain tumors.

[0005] Currently, interventional doctors are beginning to use surgical robot systems to control the delivery of interventional devices such as catheters and guidewires to improve doctors' working conditions, reduce physical exertion and reduce occupational hazards, allowing doctors to focus entirely on the surgical treatment itself and bring better surgical treatment results to patients.

[0006] In the process of delivering the catheter, the existing surgical robot has difficulty in achieving the full delivery and withdrawal of the catheter. At the same time, the delivery rate of the catheter is intermittent and the delivery accuracy is not high. In addition, the delivery process easily causes the catheter to bend and enter the vascular sheath, forming local catheter bending stress.

[0007] The existing interventional surgical robots deliver the catheter by fixing one end of the catheter, physically pushing the other end of the catheter, and shortening the distance between the two ends. To avoid bending of the catheter during delivery, a physical sleeve closed channel is used to physically prevent the microcatheter from bending. However, the delivery accuracy of this delivery method is low; and during the delivery process, there is a certain gap between the outer anti-bending guide sleeve and the outer diameter of the microcatheter, so when the microcatheter encounters travel resistance, it will bend due to its own flexible structure and insufficient rigidity, which ultimately results in insufficient delivery accuracy.

[0008] In view of this, the inventor has designed an interventional surgery catheter delivery device based on many years of production and design experience in this field and related fields and after repeated experiments, in order to solve the problems existing in the prior art. Summary of the invention

[0009] The object of the present invention is to provide an interventional surgery catheter delivery device that can achieve full delivery and withdrawal of the catheter.

[0010] To achieve the above object, the present invention provides an interventional surgery catheter delivery device, wherein the interventional surgery catheter delivery device at least comprises:

[0011] The catheter delivery box is hollow inside and has a receiving cavity. The two opposite ends of the catheter delivery box are respectively provided with an inlet and an outlet. The catheter passes through the inlet, the receiving cavity and the outlet in sequence. The guide delivery box is provided with a quick positioning connection structure.

[0012] A delivery mechanism, disposed in the accommodating cavity, the delivery mechanism drives the catheter to move along its length direction to achieve delivery and withdrawal of the catheter;

[0013] The vascular sheath connector comprises a vascular sheath fixing seat and a connecting hose, one end of the connecting hose is detachably connected to the vascular sheath fixing seat via a first quick-connect structure, and the other end of the connecting hose can be detachably connected to the outlet via a second quick-connect structure.

[0042] The details of the present invention can be more clearly understood with reference to the accompanying drawings and the description of the specific embodiments of the present invention. However, the specific embodiments of the present invention described herein are only used for the purpose of explaining the present invention and cannot be understood as limiting the present invention in any way. Under the guidance of the present invention, technicians can conceive of any possible variations based on the present invention, which should all be considered to belong to the scope of the present invention.

[0043] like Figures 1 to 8 As shown, the present invention proposes an interventional surgery catheter delivery device 100, which at least includes a catheter delivery box 10, a delivery mechanism 20 and a vascular sheath connector 30. The interior of the catheter delivery box 10 is hollow and formed with a accommodating cavity. The opposite ends of the catheter delivery box 10 are respectively provided with an inlet 11 and an outlet 12. The catheter 200 passes through the inlet 11, the accommodating cavity and the outlet 12 in sequence. A quick positioning connection structure is provided on the catheter delivery box; the delivery mechanism 20 is arranged in the accommodating cavity, and the delivery mechanism 20 drives the catheter 200 to move along the length direction of the catheter 200 to achieve the delivery and withdrawal of the catheter 200; the vascular sheath connector 30 includes a vascular sheath fixing seat 31 and a connecting hose 32, one end of the connecting hose 32 is detachably connected to the vascular sheath fixing seat 31 through a first quick-connect structure, and the other end of the connecting hose 32 is detachably connected to the outlet 12 through a second quick-connect structure.

[0044] The interventional surgery catheter delivery device 100 proposed in the present invention integrates the delivery mechanism 20 and the vascular sheath connector 30 through the catheter delivery box 10, and has both the connection function of the vascular sheath 400 and the delivery function of the catheter 200. Before the operation, the interventional surgery catheter delivery device 100 is provided as a whole to the doctor for direct use, and after the operation, the interventional surgery catheter delivery device 100 is replaced as a whole, which reduces the preparation time of the surgical robot and improves the work efficiency of medical staff.

[0045] The interventional surgical catheter delivery device 100 proposed in the present invention integrates the delivery mechanism 20 and the vascular sheath connector 30 through the catheter delivery box 10, and is provided to doctors in a sterile manner as a disposable consumable of the surgical robot, effectively solving the problem of cross infection.

[0046] The interventional surgery catheter delivery device 100 proposed by the present invention has a quick positioning connection structure on its catheter delivery box 10, through which the catheter delivery box 10 can be quickly installed on the corresponding component of the interventional surgery robot, which is convenient for the doctor's operation. At the same time, a first quick connection structure is provided between the connecting hose 32 and the vascular sheath fixing seat 31, and a second quick connection structure is provided between the connecting hose 32 and the catheter delivery box 10, which facilitates the installation of the connecting hose 32.

[0047] In an optional embodiment of the present invention, the delivery mechanism 20 includes a concentric wheel 21 and an eccentric wheel 22 that are aligned and matched, and the concentric wheel 21 and the eccentric wheel 22 are rotatably installed in the accommodating cavity, and a clamping opening 23 for the catheter 200 to pass through is formed between the concentric wheel 21 and the eccentric wheel 22. The full delivery and withdrawal of the catheter 200 can be achieved through the coordinated rolling of the concentric wheel 21 and the eccentric wheel 22.

[0048] Specifically, before the catheter 200 is placed in the clamping opening 23 between the concentric wheel 21 and the eccentric wheel 22, the eccentric wheel 22 rotates to the side away from the concentric wheel 21, and the gap between the two wheels (that is, the width of the clamping opening 23) reaches the maximum value, so as to facilitate the placement of the catheter 200. After the catheter 200 is placed, the eccentric wheel 22 rotates to achieve the eccentric wheel 22 and the concentric wheel 21 clamping the catheter 200. At this time, the concentric wheel 21 actively rotates, and the eccentric wheel 22 does not move, so that the delivery of the catheter 200 is achieved.

[0049] In an optional example of this embodiment, the concentric wheel 21 has a first rotating shaft 211, the eccentric wheel 22 has a second rotating shaft 221, the catheter delivery box 10 is provided with a first connection port 13 aligned with the first rotating shaft 211, and a second connection port 14 aligned with the second rotating shaft 221, one end of the first rotating shaft 211 passes through the first connection port 13, and one end of the second rotating shaft 221 passes through the second connection port 14 to extend out of the catheter delivery box 10, and the end of the first rotating shaft 211 extending out of the catheter delivery box 10 and the end of the second rotating shaft 221 extending out of the catheter delivery box 10 are respectively detachably connected to a driving mechanism. Further, the driving mechanism can be set on a surgical robot and can be reused, and the interventional surgery catheter delivery device 100 is detachably connected to the driving mechanism through the first rotating shaft 211 and the second rotating shaft 221, so as to facilitate the replacement of the interventional surgery catheter delivery device 100.

[0050] In an optional example, the first rotating shaft 211 and the second rotating shaft 221 are respectively connected via a third quick-connect structure, so as to further facilitate the installation of the interventional surgery catheter delivery device 100 .

[0051] Preferably, the third quick-connect structure includes a plurality of spherical protrusions 41 disposed at the end of the first rotating shaft 211 (or the end of the second rotating shaft 221) and a plurality of spherical grooves 42 disposed in the driving mechanism and aligned with the plurality of spherical protrusions 41. After the spherical protrusions 41 are aligned and inserted into the spherical grooves 42, the first rotating shaft 211 (or the second rotating shaft 221) can be quickly connected to the driving mechanism.

[0052] Furthermore, the third quick-connect structure may also be in other forms, such as a triangular protrusion or a triangular groove that matches each other.

[0053] In an optional embodiment of the present invention, the catheter delivery box 10 includes a box body 15 and a box cover 16 . The box cover 16 is openably and closably mounted on the box body 15 . The first connection port 13 and the second connection port 14 are disposed on the bottom surface of the box body 15 .

[0054] In an optional example of this embodiment, the quick positioning connection structure is a magnetic block, a positioning groove, a positioning protrusion or Velcro provided on the box body 15 .

[0055] In an optional example, a first magnetic block 17 is provided on the bottom surface of the box body 15, and correspondingly, a second magnetic block 310 is provided on the mounting fixing plate 300 of the driving mechanism, so that the catheter delivery box 10 is fixed by magnetic attraction, so that the interventional surgery catheter delivery device 100 can be quickly installed on the driving mechanism.

[0056] Preferably, the first magnetic block 17 is a magnetic stainless steel block, and two first magnetic blocks 17 are respectively embedded on both sides of the first connecting port 13 and the second connecting port 14 .

[0057] In an optional example, a positioning hole 18 is further provided on the bottom surface of the box body 15, and a corresponding positioning column is provided on the driving mechanism.

[0058] During installation, the positioning posts are correspondingly inserted into the positioning holes 18 to achieve the positioning and installation of the catheter delivery box 10, further ensuring the rapid connection and smooth operation of the spherical transmission structure.

[0059] In an optional embodiment of the present invention, the driving mechanism is a driving motor, and the rotation speed of the driving motor can be adjusted arbitrarily, so that uninterrupted and continuous stepless rotation can be achieved, thereby achieving stepless delivery of the catheter 200. Compared with the device in the prior art that requires manual delivery by the doctor, the concentric wheel 21 and the eccentric wheel 22 are driven by the driving motor to rotate, and the concentric wheel 21 and the eccentric wheel 22 can rotate continuously to achieve uninterrupted delivery of the catheter 200; in addition, the rotation speed of the concentric wheel 21 and the eccentric wheel 22 can also be changed by changing the rotation speed of the driving motor, thereby adjusting the delivery speed of the catheter 200, further improving the convenience of the doctor's operation.

[0060] In an optional embodiment of the present invention, the difference between the inner diameter of the connecting hose 32 and the outer diameter of the catheter 200 is less than 1 mm. During the process of delivering the catheter 200 into the vascular sheath, the connecting hose 32 can form a fixed sealing channel, and the connecting hose 32 can have a certain deformation toughness. After the catheter 200 penetrates the connecting hose 32, the gap between the connecting hose 32 and the catheter 200 is less than 1 mm. The bending clearance of the catheter 200 is small, which can effectively guide the delivery of the catheter 200 to ensure that the catheter 200 does not bend when it is delivered into the vascular sheath connector 30, making it easier for doctors to control the surgical robot.

[0061] In an optional example of this embodiment, one end of the connecting hose 32 is connected to the vascular sheath fixing seat 31 through a first quick-connect structure. With the first quick-connect structure, the connecting hose 32 can be quickly connected to and removed from the vascular sheath fixing seat 31. In an optional example, the first quick-connect structure is a threaded connection structure.

[0062] Furthermore, the vascular sheath fixing seat 31 is formed by buckling a vascular sheath fixing seat upper cover 311 and a vascular sheath fixing seat lower cover 312 .

[0063] In an optional example, the other end of the connecting hose 32 passes through the guide outlet 12 and extends into the accommodating cavity. A second quick-connect structure for fixing the connecting hose 32 is provided in the accommodating cavity. The second quick-connect structure is a snap-connect structure 33. The snap-connect structure 33 can avoid local hard contact and stress when adjusting the connecting hose 32 to fix with the catheter delivery box 10.

[0064] In the present invention, the first quick-connect structure and the second quick-connect structure may take various forms as long as they can achieve quick connection.

[0065] The detailed explanation of the above-mentioned embodiments is only intended to explain the present invention so as to facilitate a better understanding of the present invention. However, these descriptions cannot be interpreted as limitations on the present invention for any reason. In particular, the various features described in different embodiments may also be arbitrarily combined with each other to form other embodiments. Unless there is a clear description to the contrary, these features should be understood to be applicable to any embodiment and are not limited to the described embodiments.
