Description

Technical Field

[0001] The utility model relates to the field of IVL equipment, in particular to an IVL equipment connection structure. Background Art

[0002] Intravascular Lithotripsy (IVL) equipment can be divided into two parts according to its appearance: the main unit and the cart. In general, the main unit and the cart are used together. In special cases, the main unit needs to be separated from the cart and used alone. The cart mainly serves as a mobile platform during use. Therefore, the main unit needs to be designed as an independent portable structure and the connection between the main unit and the cart must be a movable connection to facilitate disassembly and removal of the whole unit.

[0003] In the IVL equipment in the prior art, the connection modes between the host and the cart mainly include a mechanical snap-fit ​​structure and a hand-tightened screw fastening structure.

[0004] Among them, the mechanical buckle structure is generally composed of two positioning buckles and a rotating buckle. The positioning buckle is generally designed as a male buckle at one end and a female buckle at the other end. When placed, the male and female buckles are connected and then the rotating buckle is rotated and locked. This design is relatively complex and the positioning buckle is worn out. After repeated use, there will be obvious gaps, causing problems such as host shaking. The rotating buckle structure is complex and easy to get stuck, causing problems such as being unable to place or lock. In order to ensure that the host is easy to disassemble, the buckles are not tightly connected. If accidentally touched during operation or movement, it is easy to cause the host to shake or even fall.

[0005] The design of the thumb screw fastening structure is relatively simple. After placement, the host and the cart are locked by one or two thumb screws. This structure can meet the stability requirements, but it is difficult to remove the host in certain usage situations.

[0006] It can be seen that the connection method between the IVL device host and the cart in the prior art has obvious shortcomings, which greatly affects the user's operating convenience and usage experience. Utility Model Content

[0010] Preferably, the top of the pair of magnetic poles protrudes from the first through hole, and the height of the pair of magnetic poles protruding from the first through hole is greater than the distance between the bottom surface of the electromagnet and the bottom surface of the second through hole.

[0011] Preferably, a switch button for controlling the electromagnet is provided on the host.

[0017] The following is a detailed description of the embodiments of the present invention, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0018] In order to solve the safety hazard of shaking and falling caused by accidental contact during the use or movement of IVL equipment in the prior art, as one aspect of the utility model, an IVL equipment connection structure is provided, including: a main unit 1 and a cart 2, an electromagnet 3 is arranged at the bottom of the main unit 1, and a magnetic column 4 cooperating with the electromagnet 3 is arranged in the first through hole 5 on the top surface of the cart 2, the magnetic column 4 is arranged in the first through hole 5 through a spring, and the main unit 1 and the cart 2 are connected through a magnetic attraction mechanism between the electromagnet 3 and the magnetic column 4.

[0019] Among them, the utility model can use a single large suction electromagnet as a force point to ensure the stability of the main machine placed on the cart. Furthermore, the number of electromagnets and the adsorption force can be calculated and increased according to the size of the main machine. For example, when the size of the main machine is large, two or more small suction electromagnets can be set according to actual conditions to ensure that the overall force of the main machine is uniform and the magnet column 4 is adsorbed at the same time, which can also serve as a good positioning workpiece.

[0020] Preferably, the top of the pair of magnetic poles 4 protrudes from the first through hole 5 , and the height of the pair of magnetic poles 4 protruding from the first through hole 5 is greater than the distance between the bottom surface of the electromagnet 3 and the bottom surface of the second through hole 6 .

[0021] Preferably, a second through hole 6 for accommodating the upper end of the magnetic pole 4 is provided on the bottom surface of the host 1, and the electromagnet 3 is provided above the second through hole 6, and the bottom surface of the electromagnet 3 is higher than the upper surface of the second through hole 6. Preferably, a switch button 7 for controlling the electromagnet 3 is provided on the host 1.

[0022] In the above technical solution, the connection structure in the utility model includes a switch button 7, an electromagnet 3 (de-energized electromagnet), a magnet column 4, and a spring (compression spring), wherein the electromagnet 3 is recessed in the host 1 to avoid adsorbing other debris such as metal debris, staples, etc. The upper end of the magnet column 4 protrudes from the platform where the cart 2 is placed, and a spring is arranged at the bottom of the magnet column 4, and the spring and the magnet column 4 are arranged in a mounting seat 8.

[0023] When placing the host 1, because the protruding height of the magnetic column 4 is greater than the concave depth of the electromagnet 3, the magnetic column 4 will contact the electromagnet 3 in advance, and then reach the host placement surface through spring compression, ensuring the complete contact between the magnetic column 4 and the electromagnet 3. When accidentally touched or moved, the host will not shake due to the magnetic force, which is more solid and reliable than the conventional solution.

[0024] Under special use conditions, if the user needs to take out the host 1, he only needs to operate the switch button 7 to cut off the power to the electromagnet 3 and demagnetize it, thereby separating it from the magnetic column 4. The spring generates a reaction force, making it easier to take out the host 1, and adding a one-step operation of the magnet button avoids the possibility of misoperation.

[0025] Due to the adoption of the above technical solution, the utility model adopts an electromagnet magnetic attraction structure between the main unit and the cart to connect the two into one, avoiding the risk of the main unit shaking on the cart, and when the main unit needs to be picked up, the magnet can be demagnetized by pressing the switch button, and the main unit can be easily taken out, which is more convenient for users to operate, solves the problems of poor operating convenience and poor user experience of existing equipment, avoids safety hazards during use, and greatly improves the convenience and user experience of IVL equipment operation for operators.

[0026] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
