Description

Technical Field

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

[0002] Antimicrobial interventional medical devices are designed and manufactured with materials or coatings that incorporate antimicrobial properties to reduce or prevent infections caused by microorganisms such as bacteria and fungi. Interventional medical devices, such as catheters, stents, guidewires, and artificial joints, are commonly used in diagnostic and therapeutic procedures. During medical procedures, they come into contact with tissues and fluids within the patient's body, making them a vulnerable medium for bacterial infection. Therefore, the development and application of antimicrobial interventional medical devices plays a crucial role in reducing hospital-acquired infections and improving patient treatment outcomes.

[0003] Chinese patent CN117462188B, authorized and published on March 29, 2024, discloses an interventional medical device comprising a handle housing, a catheter extending distally from the handle housing, an actuating element extending through the catheter, an actuating controller, and an actuator. The actuating element has a proximal portion and a distal portion, and the actuating controller includes a first control member, a second control member, and a buffer member located between the first and second control members. The first control member is coupled to the handle housing, and the proximal portion of the actuating element is engaged to the second control member.

[0004] In the above application documents, overload protection is provided for the execution of operations to prevent tissue damage or damage to the interventional medical device due to overload. However, when the device is in use, the catheter extending from the handle housing to the distal end is directly exposed to the outside, resulting in poor antibacterial effect. When a corresponding threaded protective sleeve is used, after the protective sleeve is removed, the threaded protective sleeve is separated from the device, making it easy to lose.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] For example 1, please refer to Figures 1-4 , an antibacterial interventional medical device, comprising: The handle housing 100 has an antibacterial coating on its outer side and a puncture needle body 200 mounted on its bottom. The protective cover 300 has an inner wall that is screw-threadedly mounted on the outer side of the handle housing 100, and a slot 400 for the puncture needle is formed at the bottom of the protective cover 300; The outer side of the protective cover 300 is fixedly connected to a fixed bin 501, and the inner wall of the fixed bin 501 is connected to a sliding block 503 by setting a spring 502. A penetrating fixed groove 504 is provided inside the sliding block 503, and the inner wall of the fixed groove 504 is connected to an extrusion block 506 by setting a spring 2 505. The bottom of the protective cover 300 is rotatably connected to a penetrating rotating shaft 507, and a transmission member for transmission is assembled between the extrusion block 506 and the rotating shaft 507. The transmission member includes a hydraulic bin 509 assembled on the outer side of the protective cover 300, and one end of the hydraulic bin 509 is slidably connected to an operating block 510 by setting a piston. The operating block 510 is located on the side of the extrusion block 506 and is in a fixed state with the extrusion block 506. When the operating block 1 510 is manually pushed toward the side close to the hydraulic tank 1 509, the operating block 1 510 drives the extrusion block 1 506 fixed thereto to move sideways, so that the extrusion block 1 506 compresses the spring 2 505 and moves into the fixed groove 1 504. Because the bottom of the extrusion block 1 506 is in an inclined state, the extrusion block 1 506 drives the sliding block 503 to move downward while moving. At this time, the sliding block 503 stretches the spring 1 502 and moves downward a certain distance, and the extrusion block 1 506 moves downward along with the operating block 1 When block 1 510 moves to the limit distance, the squeezing block 1 506 is located at the bottom notch of the fixed groove 1 504, so that the sliding block 503 loses the restriction of the squeezing block 1 506 and is reset under the action of the spring 1 502, thereby clamping the squeezing block 1 506 at the notch of the fixed groove 1 504. Similarly, the operating block 1 510 fixedly connected to the squeezing block 1 506 is restricted in the moved state. As the operating block 1 510 moves, the oil in the hydraulic tank 1 509 slidably connected to it by the piston can be squeezed.

[0022] The other end of the hydraulic tank 509 is slidably connected to the arc rod 511 through the arrangement of a piston, and the side of the rotating shaft 507 is fixedly connected to the force plate 512, which is located on the side of the arc rod 511 and is fixed to the arc rod 511. When the oil in the hydraulic chamber 1 509 is squeezed, the oil moves toward the side close to the curved rod 511, driving the curved rod 511 to move, causing the curved rod 511 to rotate the force-bearing plate 512 fixed thereto. The force-bearing plate 512 then rotates the rotating shaft 507 fixed thereto, causing the rotating shaft 507 to rotate the cover plate 508 fixed thereto, thereby opening the puncture needle passage slot 400 originally enclosed by the cover plate 508. Subsequently, the protective cover 300 can be rotated so that the protective cover 300 rotates while moving toward the handle housing 100, thereby passing the puncture needle body 200 assembled at the bottom of the handle housing 100 through the puncture needle passage slot 400 and extending out of the protective cover 300. In this way, the puncture needle body 200 can be quickly extended from the protective cover 300. At this time, the protective cover 300 is not separated from the device, which improves the antibacterial effect of the device and makes the device easier to use.

[0023] A second fixing groove 513 is provided inside the sliding block 503. The inner wall of the second fixing groove 513 is connected to the second extrusion block 515 via a third spring 514. The side of the extrusion block 515 is fixedly connected to the second operating block 516. The bottom of the rotating shaft 507 is fixedly connected to the cover plate 508. When the device is not in use, the cover plate 508 is located at the bottom of the puncture needle passage slot 400 and is in a state of closing the puncture needle passage slot 400. After the use of the device is completed, when the device is reset, the protective cover 300 is rotated in the opposite direction to retract the puncture needle body 200 into the protective cover 300, and then the operating block 2 516 is manually moved sideways, driving the extrusion block 2 515 fixedly connected to the operating block 2 516 to move sideways. At this time, the extrusion block 2 515 compresses the spring 3 514 and moves into the fixed groove 2 513, and the bottom of the extrusion block 2 515 is in an inclined state, which can drive the sliding block 503 to move downward. As the sliding block 503 moves downward, the extrusion block 1 506 can move out of the bottom notch in the fixed groove 1 504. The extrusion block 1 506 is no longer restricted by the notch and can be reset under the action of the spring 2 505, so that the cover plate 508 is reset and the puncture needle passes through the slot 400 again. Then the operating block 2 516 is released, so that the operating block 2 516 and the extrusion block 2 515 are reset under the action of the spring 3 514, so that the device can be used next time.

[0024] When in use, manually push the operating block 1 510 to the side close to the hydraulic tank 1 509. At this time, the operating block 1 510 drives the extrusion block 1 506 fixedly connected thereto to move sideways, so that the extrusion block 1 506 compresses the spring 2 505 and moves into the fixed groove 1 504. Because the bottom of the extrusion block 1 506 is in an inclined state, the extrusion block 1 506 drives the sliding block 503 to move downward while moving. At this time, the sliding block 503 stretches the spring 1 502 and moves downward a certain distance. When the extrusion block 1 506 moves to the limit distance along with the operating block 1 510, the extrusion block 1 506 is just located at the bottom notch of the fixed groove 1 504, so that the sliding block 503 is The movable block 503 loses the restriction of the squeezing block 1 506 and is reset under the action of the spring 1 502, thereby clamping the squeezing block 1 506 in the notch of the fixed groove 1 504. Similarly, the operating block 1 510 fixedly connected to the squeezing block 1 506 is restricted in the moved state. As the operating block 1 510 moves, the oil in the hydraulic tank 1 509 connected to it by the piston sliding is squeezed, so that the oil moves toward the side close to the arc rod 511, driving the arc rod 511 to move, so that the arc rod 511 drives the force plate 512 fixedly connected to it to rotate, and the force plate 512 then drives the rotating shaft 507 fixedly connected to it to rotate, so that the rotating shaft 507 drives The cover plate 508 fixedly connected thereto is rotated to open the closed puncture needle passage slot 400 originally closed by the cover plate 508. Subsequently, the protective cover 300 can be rotated so that the protective cover 300 is rotated and moved toward the handle housing 100, thereby passing the puncture needle body 200 assembled at the bottom of the handle housing 100 through the puncture needle passage slot 400 and extending out of the protective cover 300. After the use of the device is completed, when the device is reset, the protective cover 300 is rotated in the opposite direction to retract the puncture needle body 200 into the protective cover 300, and then the operating block 516 is manually moved sideways to drive the squeezing block 516 fixedly connected to the operating block 516. 15 moves to the side, at this time the squeezing block 2 515 compresses the spring 3 514 and moves into the fixed groove 2 513, and the bottom of the squeezing block 2 515 is in an inclined state, which can drive the sliding block 503 to move downward. As the sliding block 503 moves downward, the squeezing block 1 506 can move out of the bottom notch in the fixed groove 1 504. The squeezing block 1 506 is no longer restricted by the notch and can be reset under the action of the spring 2 505, so that the cover plate 508 is reset and the puncture needle passes through the groove 400 again. Then the operating block 2 516 is released, so that the operating block 2 516 and the squeezing block 2 515 are reset under the action of the spring 3 514.

[0025] For example 2, please refer to Figures 1-6On the basis of embodiment one, the interior of the handle housing 100 is equipped with an auxiliary anti-slip component 600 for preventing slipping. The auxiliary anti-slip component 600 includes anti-slip pads 609 installed on both sides of the handle housing 100. The side of the protective cover 300 is equipped with a hydraulic tank 2 601. One side of the hydraulic tank 2 601 is slidably connected to a transmission rod 1 602 by setting a piston. The transmission rod 1 602 is located on the side of the operating block 1 510 and is fixed with the operating block 1 510. The other side of the hydraulic tank 2 601 is equipped with a hose 603. When the operating block 1 510 moves sideways, it can drive the transmission rod 1 602 fixed to it to move sideways. Because the hydraulic tank 2 601 and the transmission rod 1 602 are connected by a piston sliding connection, the oil in the hydraulic tank 2 601 is drawn out by the transmission rod 1 602 as the transmission rod 1 602 moves, and the pressure in the hydraulic tank 2 601 decreases accordingly, causing the oil in the hose 603 connected to the hydraulic tank 2 601 to flow into the hydraulic tank 2 601.

[0026] The interior of the handle housing 100 is equipped with a penetrating hydraulic chamber three 604, and the top of the hydraulic chamber three 604 is slidably connected to a limiting block 605 by setting a piston. The inner wall of the handle housing 100 is fixedly connected to a fixing plate 606, and the side of the fixing plate 606 is connected to a top block 608 by setting a spring four 607. A groove is provided at the bottom of the top block 608. When the auxiliary anti-slip component 600 is not activated, the limiting block 605 is located in the groove. When the oil in the hose 603 flows into the hydraulic tank two 601, and the other end of the hose 603 is connected to the hydraulic tank three 604, the oil in the hydraulic tank three 604 flows into the hose 603, thereby driving the limiting block 605, which is slidably connected to the hydraulic tank three 604 by the piston, to move downward. The limiting block 605 is then moved out from the bottom groove of the top block 608, thereby canceling the restriction on the top block 608, so that the top block 608 moves sideways under the action of the spring four 607, applying an additional force to the anti-slip pad 609, and at this time the user's hand is in a state of gripping the handle shell 100, thereby increasing the friction between the anti-slip pad 609 and the hand, further reducing the possibility of the device accidentally falling.

[0027] When in use, based on the first embodiment, when the operating block 1 510 moves to the side, it can drive the transmission rod 1 602 fixed thereto to move to the side, and because the hydraulic chamber 2 601 and the transmission rod 1 602 are connected by a piston sliding connection, the oil in the hydraulic chamber 2 601 is drawn out by the transmission rod 1 602 as the transmission rod 1 602 moves, and the pressure in the hydraulic chamber 2 601 decreases accordingly, causing the oil in the hose 603 connected to the hydraulic chamber 2 601 to flow into the hydraulic chamber 2 601, and the other end of the hose 603 is connected to the hydraulic chamber 2 The tank three 604 is connected, so that the oil in the hydraulic tank three 604 flows into the hose 603, thereby driving the limiting block 605 which is slidably connected to the hydraulic tank three 604 by the piston to move downward, and the limiting block 605 is then moved out from the bottom groove of the top block 608, thereby canceling the restriction on the top block 608, so that the top block 608 moves sideways under the action of the spring four 607, applying an additional force to the anti-slip pad 609, and at this time the user's hand is in a state of gripping the handle shell 100, thereby increasing the friction between the anti-slip pad 609 and the hand.

[0028] For example three, please refer to Figures 1-8 On the basis of the first and second embodiments, the interior of the protective cover 300 is equipped with a disinfection assembly 700 for disinfecting the puncture needle body 200. The disinfection assembly 700 includes a hydraulic chamber 4 701. The hydraulic chamber 4 701 is located to the side of the hydraulic chamber 1 509 and is connected to the hydraulic chamber 1 509. The side of the hydraulic chamber 4 701 is slidably connected to the transmission rod 2 702 via a piston. When the oil in the hydraulic chamber 1 509 is squeezed and moves, some of the oil flows into the hydraulic chamber 4 701 connected to it, causing the oil originally stored in the hydraulic chamber 4 701 to move due to the squeezing. The oil then moves to the side close to the transmission rod 2 702, driving the transmission rod 2 702, which is slidably connected to the hydraulic chamber 4 701 via the piston, to move sideways.

[0029] One end of the second transmission rod 702 is equipped with a spring 703, and the other end of the second transmission rod 702 is equipped with a cleaning plate 704 coated with medical alcohol. When the second transmission rod 702 moves sideways, it causes the cleaning plate 704, which is fixedly connected to the second transmission rod 702 and coated with medical alcohol, to move. At this time, the cleaning plate 704 coated with medical alcohol moves to the side of the puncture needle body 200. When the puncture needle body 200 is extended, the cleaning plate 704 rotates and smears the puncture needle body 200 as the protective cover 300 moves, further enhancing the antibacterial effect of the puncture needle body 200.

[0030] During use, based on Example 1 and Example 2, when the oil in the hydraulic tank 1 509 is squeezed and moves, part of the oil flows into the hydraulic tank 4 701 connected thereto, causing the oil originally stored in the hydraulic tank 4 701 to move due to being squeezed, and the oil moves to the side close to the transmission rod 2 702, driving the transmission rod 2 702, which is slidably connected to the hydraulic tank 4 701 by setting a piston, to move sideways, so that the transmission rod 2 702 drives the cleaning plate 704, which is fixedly connected thereto and has medical alcohol on its surface, to move. At this time, the cleaning plate 704, which has medical alcohol on its surface, moves to the side of the puncture needle body 200. When the puncture needle body 200 is extended, the cleaning plate 704 can rotate and apply the puncture needle body 200 as the protective cover 300 moves.

[0031] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
