[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0040] The following is combined with Figures 1 to 7 The present invention describes the cardiac ultrasound catheter handle operating device.

[0041] like Figure 1 As shown, the cardiac ultrasound catheter handle 7 includes a catheter 75, a first rotating part 71, a second rotating part 72, a handheld part 73, and a front end 74. The first rotating part 71 is used to adjust the left and right bending of the front end 74, and the second rotating part 72 is used to adjust the up and down bending of the front end 74.

[0042] like Figure 1 As shown, the cardiac ultrasound catheter handle operating device of this embodiment includes: a housing 1, a rotating component 3, a linear movement component 2, a first clamping rotating component 4, and a second clamping rotating component 5.

[0043] The housing 1 is provided with a storage space 11 and a first opening 12 communicating with the storage space 11. The intracardiac ultrasound catheter handle 7 is adapted to be fixed in the storage space 11, and the front end 74 of the intracardiac ultrasound catheter handle 7 is exposed to the housing 1 through the first opening 12.

[0044] Furthermore, both the first clamping rotating assembly 4 and the second clamping rotating assembly 5 are installed within the storage space 11 and correspond to the two rotating parts of the intracardiac ultrasound catheter handle 7, respectively. Both the first clamping rotating assembly 4 and the second clamping rotating assembly 5 are configured to clamp and rotate the corresponding rotating part. For example, the first clamping rotating assembly 4 corresponds to the first rotating part 71, and under the action of the first clamping rotating assembly 4, the first rotating part 71 can be driven to rotate, thereby adjusting the left-right bending of the front end 74. The second clamping rotating assembly 5 corresponds to the second rotating part 72, and under the action of the second clamping rotating assembly 5, the second rotating part 72 can be driven to rotate, thereby adjusting the up-down bending of the front end 74.

[0045] Furthermore, the housing 1 is connected to the linear motion assembly 2 via a rotating assembly 3. The rotating assembly 3 is configured to drive the housing 1 to rotate, thereby causing the intracardiac ultrasound catheter handle 7 to rotate along its own central axis. Under the action of the linear motion assembly 2 and the rotating assembly 3, the intracardiac ultrasound catheter handle 7 can rotate around its own central axis and move forward or backward along its own length.

[0046] In practical applications, users can control the movements of the rotating component 3, the linear movement component 2, the first clamping rotating component 4, and the second clamping rotating component 5 in real time according to actual needs. Under the action of the first clamping rotating component 4, the first rotating part 71 can be driven to rotate, thereby adjusting the left and right bending of the front end 74. Under the action of the second clamping rotating component 5, the second rotating part 72 can be driven to rotate, thereby adjusting the up and down bending of the front end 74. Under the action of the linear movement component 2, the intracardiac ultrasound catheter handle 7 can move forward or backward along its own length direction. Under the action of the rotating component 3, the intracardiac ultrasound catheter handle 7 can rotate around its own central axis. Thus, functions such as automatic feeding, rotation, and bending control can be realized.

[0047] In optional embodiments, such as Figure 1 , Figure 2 and Figure 3As shown, the linear motion assembly 2 includes a base plate 21, a guide rail 22, a slider 23, a first fixed seat 26, and a first driving component. The guide rail 22 is mounted on the base plate 21, and the first fixed seat 26 slides with the guide rail 22 through the slider 23. The first driving component is mounted on the base plate 21 and is configured to drive the first fixed seat 26 to move relative to the base plate 21. The rotating assembly 3 is mounted on the first fixed seat 26.

[0048] Specifically, there are two guide rails 22, which are fixed side-by-side to the base plate 21. Each guide rail 22 has at least one slider 23 mounted on it. For example, each guide rail 22 has two sliders 23. The first fixed seat 26 is an L-shaped fixed seat, with its bottom wall mounted on each slider 23. The rotating assembly 3 is mounted on the side wall of the L-shaped fixed seat. Thus, driven by the first driving member, the rotating assembly 3 can move linearly relative to the base plate 21. A reinforcing plate can also be installed between the bottom wall and the side wall of the L-shaped fixed seat.

[0049] In practical applications, such as Figure 1 , Figure 2 and Figure 3 As shown, the first driving component includes a first lead screw 27, a first lead screw nut 25, and a first drive motor 24. The first drive motor 24 is connected to the first lead screw 27 in a transmission connection, and the first fixed seat 26 is connected to the first lead screw 27 through the first lead screw nut 25.

[0050] Specifically, the first lead screw 27 is positioned between two guide rails 22, parallel to the guide rails 22. One end of the first lead screw 27 is fitted with a bearing, which is mounted on the base plate 21 via a support. The other end of the first lead screw 27 is fitted with another bearing, which is also mounted on the base plate 21 via another support. The output shaft of the first drive motor 24 is connected to one end of the first lead screw 27 via a coupling. The first lead screw nut 25 is connected to the bottom wall of the L-shaped fixed seat.

[0051] In optional embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the rotating assembly 3 includes a first mounting base, a second fixed base 33, and a second driving member. The first mounting base has a first side and a second side opposite to each other. The housing 1 is mounted on the first side. The second side is provided with a first arc-shaped guide portion. The second fixed base 33 is provided with a first arc-shaped guide groove. The first arc-shaped guide portion is slidably mounted in the first arc-shaped guide groove. The second driving member is mounted on the second fixed base 33 and is connected to the first mounting base in a transmission manner.

[0052] Specifically, the second mounting base 33 has a first mounting surface and a second mounting surface opposite to each other. The first mounting surface is connected to the side wall of the L-shaped mounting base, and the second mounting surface is provided with a first arc-shaped guide groove. Under the drive of the second driving member, the first arc-shaped guide part can move along the first arc-shaped guide groove, thereby realizing the rotation of the intracardiac ultrasound catheter handle 7 along its own central axis. The first arc-shaped guide groove can be a semi-annular guide groove, and the first arc-shaped guide part can be a semi-annular guide part.

[0053] In practical applications, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first mounting base includes a first incomplete worm gear 31 and a first semi-annular guide rail 32. The first semi-annular guide rail 32 forms a first arc-shaped guide portion. The second fixed base 33 is provided with a plurality of first rollers 34. The plurality of first rollers 34 are arranged side by side to form two rows of roller groups. A first arc-shaped guide groove is formed between the roller groups.

[0054] Specifically, four first rollers 34 are provided on the second mounting surface of the second fixed seat 33. Thus, each row of rollers includes two first rollers 34, and the four first rollers 34 form a semi-annular guide groove. The first semi-annular guide rail 32 is slidably installed in the semi-annular guide groove.

[0055] For example, in order to improve the movement stability of the first semi-annular guide rail 32 in the semi-annular guide groove, each first roller 34 is formed with a V-shaped recess, and correspondingly, the contact surface between the first semi-annular guide rail 32 and the first roller 34 is formed with a V-shaped protrusion.

[0056] It should be noted that the side of the first incomplete worm gear 31 facing away from the first semi-annular guide rail 32 is fixedly connected to the housing 1 by a shim 37, wherein the shape of the shim 37 is adapted to the shape of the first incomplete worm gear 31.

[0057] In addition, the second driving component includes a first worm 36 and a second drive motor 35. The second drive motor 35 is connected to the first worm 36 in a transmission connection, and the first worm 36 is engaged with a first incomplete worm wheel 31.

[0058] Specifically, the second fixed base 33 includes a roller mounting plate and a worm mounting base. The worm mounting base is provided with mounting holes. Both ends of the first worm 36 are mounted in the corresponding mounting holes through bearings. The four first rollers 34 are rotatably mounted on the roller mounting plate. When the first semi-annular guide rail 32 is slidably mounted in the semi-annular guide groove, the first incomplete worm wheel 31 can mesh with the first worm 36. Driven by the second drive motor 35, the first worm 36 rotates. Driven by the first worm 36, the first incomplete worm wheel 31 can rotate in the plane where the roller mounting plate is located.

[0062] It should be noted that the size of the clamping space is adjusted to match the first rotating part 71, so that the clamping assembly can clamp the first rotating part 71. Under the drive of the third driving member, the second mounting base can rotate, so that the clamping assembly located on the second mounting base can drive the first rotating part 71 to rotate, thereby realizing the left and right bending of the front end 74.

Driven by the third drive motor 404, the second worm 403 rotates. Driven by the second worm 403, the second incomplete worm wheel 401 can rotate within the plane of the roller mounting plate.
