Abstract
Description
Cassette mis-mounting prevention system
[0001] The present invention relates to a system equipped with a cassette for guiding at least one of a catheter and a guide wire used for minimally invasive interventional procedures.
[0002] A guide wire is used to guide a secondary sheath (e.g., a catheter) along the guide wire to a desired location in the body, e.g., a mammalian body, such as a human body. In one application, the guide wire is introduced into a body lumen, i.e., a blood vessel, through an incision in the patient's skin and lumen wall, and the introduction or distal end of the guide wire is guided therefrom to a desired location in the lumen or into a secondary lumen branching from the lumen. Alternatively, a catheter is guided along the guide wire.
[0003] One challenge with guidewire and catheter introduction systems is the difficulty in positioning the distal tip of the guidewire along the tortuous lumen geometry, positioning it in a branch lumen away from the primary lumen it initially traversed. In some cases, the intended destination of the distal tip of the guidewire and catheter is a branch lumen where the distal tip intersects a lumen at a large angle, for example, greater than 45 degrees, and in some cases, greater than 90 degrees.
[0004] To facilitate the control of the distal end of the guide wire and catheter, a robotic system is proposed to stably control the movement of the guide wire and catheter. A cassette for use with the robotic system is also proposed. The cassette guides the guide wire and catheter to the desired location in the body through forward, backward, or rotational movements.
[0005] However, when multiple cassettes with similar appearances are mounted on a single system, there is a possibility that malfunction may occur if the user mounts a cassette in the wrong location on the system.

[0009] The technical problem to be achieved by the present invention is to provide a system in which a plurality of cassettes for guiding at least one of a guide wire and a catheter on the guide wire are mounted, and in which each cassette is mounted at an accurate position in the system for that cassette to prevent malfunction of the system.
[0010] According to one embodiment of the present invention, a system comprises a housing (100) extending longitudinally from the front (101) to the rear (102), a plurality of cassette actuators (300) disposed within the housing (100) and each configured to drive one of the cassettes (200), and a plurality of drape plates (400) mounted with the cassettes and disposed between each cassette actuator (300) and each cassette (200), wherein at least one of the plurality of drape plates (400) includes a protruding portion (500) defining a joining site at which the cassettes (200) are joined, and any two drape plates of the plurality of drape plates (400) have different numbers of protruding portions (500).
[0011] A system according to one embodiment of the present invention comprises a housing (100) extending longitudinally from the front (101) to the rear (102), a plurality of cassette actuators (300) disposed within the housing (100) and each configured to drive one of the cassettes (200), and a plurality of drape plates (400) mounted with the cassettes and disposed between each cassette actuator (300) and each cassette (200), at least one of the plurality of drape plates (400) includes a protruding portion (500) defining a joining site at which the cassettes (200) are joined, and any two drape plates of the plurality of drape plates (400) have different positions at which the protruding portions (500) are formed.
[0012] A system according to one embodiment of the present invention comprises a housing (100) extending longitudinally from the front (101) to the rear (102), a plurality of cassette actuators (300) disposed within the housing (100) and each configured to drive one of the cassettes (200), and a plurality of drape plates (400) mounted with the cassettes and disposed between each cassette actuator (300) and each cassette (200), at least one of the plurality of drape plates (400) includes a protruding portion (500) defining a joining site to which the cassettes (200) are joined, and any two drape plates of the plurality of drape plates (400) have different shapes of the protruding portions (500).
[0013] According to one embodiment of the present invention, a system may have a protruding portion (500) formed at a longitudinal rear end of a drape plate (400).
[0014] According to one embodiment of the present invention, at least one of the plurality of cassettes (200) mounted on the system (1000) includes at least one groove (600) formed to engage with the protruding portion (500).
[0015] According to one embodiment of the present invention, a plurality of cassettes (200) mounted on the system (1000) may include at least one catheter fixation cassette (210) coupled to a proximal end of a catheter, at least one catheter drive cassette (220) for pinching the catheter to drive the catheter, and a guide wire drive cassette (230) for pinching the guide wire to drive the guide wire.

[0019] Figure 2 is a perspective view of a system according to the present invention.
[0020] Figure 3 is a plan view of a system according to the present invention.
[0021] Figures 4a to 4d are perspective views showing a state in which a cassette is mounted on a drape plate in a system according to the present invention.
[0022] Hereinafter, preferred embodiments of the present invention will be described with reference to the attached drawings.
[0023] Catheters, guide wires, and cassettes are sterilized before use and are not reused to prevent cross-infection. However, since the cassette actuator for driving the cassette must be reused, as shown in FIG. 1, a drape (drape, D) is installed between the cassette actuator (300) and the cassette (200) to prevent contamination of the cassette actuator (300) with blood, drugs, etc., and a drape plate (400) is placed between the cassette (200) and the drape (D), thereby forming a sterile barrier between the cassette (200) and the system (1000).
[0024] Referring to FIGS. 2 to 4d, a system (1000) for guiding at least one of a guide wire and a catheter of the present invention includes a housing (100) extending longitudinally from anterior (101) to posterior (102), a plurality of cassette actuators (300) disposed within the housing (100) and each configured to drive one of the cassettes (200), and a plurality of drape plates (400) disposed between the cassette actuators (300) and the cassettes (200).
[0025] In the system (1000) of the present invention, the number of cassette actuators (300) and drape plates (400) is not particularly limited, and one cassette (200) is arranged on one drape plate (400), and the drape plate (400) is positioned on a specific cassette actuator (300) configured to drive a specific cassette (200), so that the system (1000) operates normally when each cassette (200) is arranged in the correct order from the front (101) to the rear (102) of the housing (100).
[0026] FIGS. 2 and 3 illustrate a system (1000) according to one embodiment of the present invention, which includes a total of four cassette actuators (300) and a total of four drape plates (400). Here, the surfaces of the cassette actuators (300) used to control the position of the catheter in the system, which face the cassettes, have the same plane profile, and the interface system connecting the cassettes (200) and the cassette actuators (300) is also the same. In such a case, there is a problem that the user may place the cassettes (200) in the wrong positions, so that the cassettes (200) are not arranged in the correct order from the front (101) to the back (102), which may cause the system (1000) to malfunction.
[0027] In order to solve such a problem, the present invention is characterized in that at least one of a plurality of drape plates (400) includes a protruding portion (500), and any two drape plates of the plurality of drape plates (400) have different numbers of protruding portions (500), different positions where the protruding portions (500) are formed, and / or different shapes of the protruding portions (500).
[0028] At this time, the protruding portion (500) formed on the drape plate (400) defines the joining site where the cassette (200) is joined.
[0029] Each cassette (200) is configured to drive or control the position of a different catheter or guide wire to which it is coupled. Therefore, it is important to mount the correct cassette (200) on the correct cassette actuator (300) with the drape plate (400) interposed therebetween. Accordingly, at least one of the plurality of cassettes (200) may include a groove (600) formed to mate only with a protruding portion (500) of the drape plate (400) in the cassette actuator (300) that drives it, wherein the groove (600) is aligned with the protruding portion (500) of the drape plate (400) at the correct position at which the cassette (200) is coupled to the system (1000) when mounted on the drape plate (400).
[0030] In this way, by making the number, position and / or shape of the protruding portions (500) of any two drape plates among the plurality of drape plates (400) different, if the cassette (200) is not arranged on the drape plate (400) at the correct position, it is impossible to engage with the drape plate (400) at the wrong position, thereby preventing the user from arranging the cassette (200) at the wrong position, thereby preventing malfunction of the system (1000).
[0031] More specific embodiments of the present invention are illustrated in FIGS. 4a to 4d.
[0032] FIGS. 4A to 4D relate to an embodiment of the present invention in which any two drape plates (500) among a plurality of drape plates have different numbers of protruding portions (500), and each cassette (200) is positioned at a precise position on each drape plate (400). Here, as illustrated in FIG. 4D, the guide wire cassette (230) and the immediately adjacent catheter fixation cassette (210) are coupled to a drape plate (400) that is different in size from the other drape plates (400) of the system.
[0033] The drape plate (400) may or may not include a protruding portion (500) defining a joint portion with the cassette (200).
[0034] For example, each drape plate (400) of FIGS. 4a to 4d includes 0, 1, 2, or 3 protruding portions (500), respectively.
[0035] Accordingly, each cassette (200) includes 0, 1, 2 or 3 corresponding grooves (600) to engage with the protruding portions (500) of the drape plate (400) at the precise location of each cassette (200). The drape plates for the guide wire cassette (230) and the immediately adjacent catheter securing cassette (210) are of different sizes from the other drape plates and therefore do not have protruding portions (500) and the guide wire cassette (230) does not have grooves (600).
[0036] In this way, by making the number of protruding portions (500) of each drape plate (400) and the number of grooves (600) of each cassette (200) different from each other, the cassettes (200) and drape plates (400) having different numbers of protruding portions (500) and grooves (600) cannot be combined with each other.
[0037] Therefore, even if the user tries to combine the cassette (200) to the drape plate (400) in an incorrect position, the combination will not be possible, and the user can combine each cassette (200) in the correct position in the system (1000).
[0038] In the present invention, the position at which the protruding portion (500) is formed on the drape plate (400) is not particularly limited, but the protruding portion (500) may be formed at the longitudinal rear end of the drape plate (400).
[0039] The type of cassette mounted on the system (1000) of the present invention is not particularly limited, but may include at least one catheter fixing cassette (210) to which the proximal end of the catheter is coupled, at least one catheter driving cassette (220) that pinches the catheter to drive the catheter, and a guide wire driving cassette (230) that pinches the guide wire to drive the guide wire.
[0040] In the present invention, the type of cassette in which the groove (600) is formed is not particularly limited, but the groove (600) can be formed in at least one catheter driving cassette (220) or guide wire driving cassette (230).
[0041] In addition, similar to the embodiment in which the number of protruding portions (500) of any two drape plates (400) of FIGS. 4a to 4d are different from each other, even if the formation positions of the protruding portions (500) of any two drape plates (400) are made different or the shapes of the protruding portions (500) are made different, each cassette (200) can be arranged at an accurate position, thereby preventing malfunction of the system (1000).
[0042] The present invention is not limited to the above-described embodiments and the attached drawings, and various substitutions, modifications, and changes may be made by those skilled in the art within the scope of the technical idea of the present invention described in the claims, and this also falls within the scope of the present invention.
