Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a cardiovascular intubation care clip. Background Technology
[0002] Cardiovascular intubation plays a vital role in modern medicine, especially in heart and vascular surgeries, where the stability and safety of intubation directly affect the success rate of the surgery and the patient's postoperative recovery.
[0003] A search revealed that Chinese utility model patent CN220801660U discloses a cardiovascular cannula care clamp, including a first clamping rod, a pin shaft at the middle of the first and second clamping rods, a clamping plate at the same end of both the first and second clamping rods, an arc-shaped strip fixedly connected to the side of the first clamping rod away from the clamping plate, a push plate inside a slot, a movable groove in the middle of the push plate, a serrated groove on one side of the arc-shaped strip, a locking plate at one end of the movable groove, the push plate engaging with the arc-shaped strip through the locking plate and the serrated groove in the movable groove, the push plate being driven to move by a lever, and a return spring enabling it to return to its original position after movement, allowing the locking plate in the movable groove to quickly return to its original position after separation from the serrated groove, and the locking plate engaging with the serrated groove to achieve the purpose of locking and fixing the first and second clamping rods after clamping, thereby ensuring the stability of the clamping plate and achieving the function of stabilizing the cannula.
[0004] The application achieves clamping operation through the design of the ring and dial, but doctors need to use their thumb, middle finger and index finger at the same time to operate. This may increase the complexity and time of operation in emergency or rapid response situations. Furthermore, prolonged use of the ring and dial may cause finger fatigue, especially for medical staff who need to perform cardiovascular surgery for long periods of time. Utility Model Content
[0005] In view of the above-mentioned prior art, the present invention provides a cardiovascular intubation care clip, which mainly solves the technical problem of how to simplify the operation process, reduce the complexity of operation, reduce finger fatigue, and improve the comfort of medical staff.
[0006] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:
[0007] A cardiovascular cannula care clamp includes two intersecting clamping rods and a handheld part. The middle parts of the two clamping rods are rotatably connected to one end of the handheld part by a pin. The top of the clamping rods are respectively provided with mutually cooperating clamping parts. The other end of the clamping rods is rotatably connected to a connecting rod. The end of the connecting rod away from the clamping rod is rotatably connected to a slider by a pin. The handheld part is provided with a limiting mechanism that drives the slider to move and open and close the clamping rods.
[0008] Furthermore, the limiting mechanism includes a slide groove located in the middle of the handheld part, a slider slidably connected to the slide groove, several limiting teeth on opposite sides of the slide groove, a parallel elastic rod fixedly connected to the end of the slider away from the connecting rod, and a locking tooth that cooperates with the limiting teeth fixedly installed at the end of the elastic rod away from the slider.
[0009] Furthermore, a limit plate is slidably connected to the end of the slider away from the connecting rod, and a limit block is fixedly installed at the bottom of the limit plate. The limit block is located between two elastic rods. When the limit plate moves away from the slider, the limit block drives the locking teeth to engage with the limit teeth.
[0010] Furthermore, a stop is provided on one side of the elastic rod that is away from the slider.
[0011] Furthermore, push blocks are provided on the limiting plate and the slider.
[0012] Furthermore, the clamping part is arc-shaped.
[0013] Furthermore, elastic pads are provided on the side where the clamping parts are close to each other.
[0014] Furthermore, the clamping parts are provided with several elastic cones on one side close to each other.
[0015] The beneficial effects of this utility model are as follows:
[0016] 1. Medical staff can hold the handpiece and use their thumb to move the slider and limit plate to drive the two clamping rods to move closer together to clamp the intubation tube or move away from each other to release the intubation tube. It is simple to use. Only one finger is needed to operate after holding the handpiece. Compared with the operation of the ring for a long time, the operation method of holding the handpiece can reduce finger fatigue and improve the comfort of medical staff.
[0017] 2. Through the design of the limiting plate, when the slider moves to the desired position, the limiting block can be locked between the two elastic rods, and the locking teeth on the limiting rods are engaged with the limiting teeth, locking the position of the slider. This double locking mechanism ensures the stability of the insertion tube during the clamping process and avoids accidents caused by loosening of the device;
[0018] 3. Several elastic cones are provided on one side of the clamping part, and the elastic cones are evenly arranged along the inner side of the clamping part. When the clamping part applies pressure to the insertion tube, the pressure will gradually increase along the inclined surface of the cone, thereby increasing the clamping force of the clamping part on the clamped object, which helps to ensure that the clamped object is not easy to fall off or loosen when subjected to external force.

[0026] Example 1
[0027] See attached document Figure 1-2This application provides a cardiovascular cannula care clamp, including a handle 2 with anti-slip texture. Two clamping rods 1 are rotatably connected to one end of the handle 2 via a pin. The two clamping rods 1 are arranged in a scissor-like cross configuration. Clamping parts 3 are fixedly installed at the ends of the two clamping rods 1 away from the handle 2, for clamping the cardiovascular cannula. The clamping parts 3 are arc-shaped, and elastic pads 14 are provided on the sides of the clamping parts 3 that are close to each other to improve clamping stability and reduce pressure marks on the cannula surface. Connecting rods 4 are rotatably connected to the ends of the clamping rods 1 away from the clamping parts 3. A slider 5 is rotatably connected to the end of the connecting rod 4 away from the clamping rod 1 via a pin. The handle 2 is provided with a limiting mechanism that drives the slider 5 to move and open / close the clamping rods 1.
[0028] The limiting mechanism includes a groove 6 located in the middle of the handheld part 2. The slider 5 is slidably connected in the groove 6. Several limiting teeth 7 are provided on opposite sides of the groove 6. Two parallel elastic rods 8 are fixedly connected to the end of the slider 5 away from the connecting rod 4. The elastic rods 8 are supported by elastic material. A locking tooth 9 that cooperates with the limiting tooth 7 on the same side is fixedly installed on the end of the elastic rod 8 away from the slider 5. A stop block 12 is provided on one side of the elastic rods 8 away from the slider 5. A limiting plate 10 is slidably connected to the end of the slider 5 away from the connecting rod 4. A limiting block 11 is fixedly installed at the bottom of the limiting plate 10. The limiting block 11 is located between the two elastic rods 8 and the stop block 12. When the limiting plate 10 moves to the end away from the slider 5, the limiting block 11 drives the locking tooth 9 to engage with the limiting tooth 7.
[0029] The limiting plate 10 and the slider 5 are equipped with push blocks 13, which facilitates medical staff to move the limiting plate 10 and the slider 5.
[0030] Working principle:
[0031] Initially, the limiting plate 10 is inside the slider 5. When it is necessary to clamp the intubation tube, the medical staff holds the handle 2 and uses their thumb to push the push block 13 on the slider 5, causing the slider 5 to move away from the clamping part 3. During the movement of the slider 5, the elasticity of the elastic rod 8 causes the clamping teeth 9 to vibrate along the limiting teeth 7. This push process generates a damping sensation, causing the slider 5 to drive the two connecting rods 4 connected to the slider 5 to reduce their angle, causing the two clamping rods 1 to move closer to each other until the intubation tube is clamped and the clamping teeth 9 engage with the limiting teeth 7. Then, the thumb moves the push block 13 on the limiting plate 10, causing the limiting plate 10 to move away from the clamping part 3. The limiting block 11 at the bottom of the limiting plate 10 moves towards the limiting tooth 7, so that the limiting block 11 is stuck between the two elastic rods 8. The elastic rods 8 can no longer move, and the locking tooth 9 on the limiting rod is stuck in the limiting tooth 7, locking the position of the slider 5, so that the clamping rod 1 can stably clamp the tube. At this time, only the hand part 2 needs to be held, reducing finger fatigue and improving the comfort of medical staff.
[0032] When the insertion tube needs to be released, push the limiting plate 10 with your thumb to move it closer to the slider 5. Then the limiting block 11 will move away from the locking tooth 9. At this time, you can use your thumb to push the push block 13 on the slider 5 to move the slider 5 closer to the clamping part 3. The two clamping rods 1 will move away from each other, releasing the insertion tube. It is simple to use and only requires one finger to operate.
[0033] Example 2
[0034] See attached document Figure 3 This application provides a cardiovascular cannula care clamp. Compared with embodiment 1, in order to enhance the clamping force and improve the clamping stability, the clamping part 3 is provided with a plurality of elastic cones 15 close to each other on one side. The plurality of elastic cones 15 are evenly arranged along the inner side of the clamping part 3. When the clamping part 3 applies pressure to the cannula, the pressure will gradually increase along the inclined surface of the cone, thereby increasing the clamping force of the clamping part 3 on the clamped object, which helps to ensure that the clamped object is not easy to fall off or loosen when subjected to external force.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
