Abstract
Description
Technical Field
[0001] This invention relates to the field of puncture positioning technology, and more specifically, to a cardiology puncture auxiliary positioning device. Background Technology
[0002] Cardiac puncture usually refers to the technique of percutaneously puncturing blood vessels or heart chambers under the guidance of medical imaging (such as ultrasound and X-ray fluoroscopy) to establish access or directly perform interventional procedures. The first step in most cardiac interventional procedures is to establish an interventional access through vascular puncture. The main means of establishing an interventional access are radial artery puncture and femoral artery puncture. In very rare cases, access is established through brachial artery puncture.
[0003] However, most existing cardiology puncture-assisted positioning devices lack the function of guiding the puncture direction. After determining the optimal puncture point, most of them require medical staff to test the puncture direction themselves. Judging the puncture direction by human experience can easily lead to puncture failure and damage to blood vessels, thereby reducing puncture efficiency. Summary of the Invention
[0004] This invention provides a cardiac puncture auxiliary positioning device to solve the problem that most existing cardiac puncture auxiliary positioning devices lack the function of guiding the puncture direction. Most of them require medical staff to test the puncture direction themselves after determining the optimal puncture point, which can easily lead to puncture failure and damage to blood vessels.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A cardiology puncture auxiliary positioning device includes two pairs of fixation frames, which are arranged opposite each other. The upper pair of fixation frames are connected by a connecting rod, and the other pair of fixation frames are fixedly connected to both sides of an extension plate. The bottom of the fixation frame has multiple slots, and a connecting plate is slidably engaged in each slot. The two opposite connecting plates are connected by fastening straps, and the fastening straps connected to the two pairs of fixation frames are staggered in the horizontal direction.
[0007] Preferably, a plurality of fixed shafts are fixedly connected to the end of the fixed frame away from the extension plate, and two pairs of fixed shafts are rotatably connected to a pair of first swing rods and a pair of second swing rods, respectively. The free ends of the first swing rods and the second swing rods are hinged together, and a control component is provided at one end of the extension plate.
[0008] Preferably, the control component includes two pairs of crossbars fixedly connected to both sides of the extension plate, and two first screws rotatably connected between the two pairs of crossbars, with the two first screws coaxially connected.
[0009] Preferably, a movable frame is provided on the first screw, and two movable frames are slidably locked between two pairs of crossbars. A drive shaft is fixedly connected to the top of the movable frame, and the drive shaft is simultaneously hinged to the first swing arm and the second swing arm.
[0010] Preferably, a fixing component is provided at the end of the extension plate away from the control component. The fixing component includes a telescopic pad that is slidably connected to the extension plate, a connecting seat that is fixedly connected to the top of the telescopic pad, a fixing ring that is hinged to the top of the connecting seat, and guide grooves that are provided on both sides of the fixing ring.
[0011] Preferably, a pressure frame is slidably mounted in the guide groove, and a second screw is rotatably mounted in the guide groove. The pressure frame passes through the second screw, the axis of the second screw is parallel to the guide groove, and a finger ring is provided at the free end of the pressure frame.
[0012] Preferably, the extension plate is provided with an auxiliary component, which includes a connecting arm fixedly connected to the top of the telescopic rod, a turntable being rotatably mounted on the free end of the connecting arm, and a test plate being fixedly connected to the bottom end of the turntable.
[0013] Preferably, the bottom of the test board is provided with multiple sensor contacts, and the sensor contact group can detect the line with the strongest vibration. The test board is provided with a guide window, and multiple lasers are provided inside the guide window. The direction of the laser beam is the same as the direction of the line measured by the sensor contacts.
[0014] Preferably, a control button is eccentrically connected to the top of the turntable, a drive rod is sleeved on the outside of the control button, and a longitudinal rod is fixedly connected to the bottom of the drive rod.
[0015] Preferably, a sliding button is connected to the outside of the longitudinal rod, a drive sleeve is fixedly connected to the extension plate, a helical groove and a longitudinal groove are opened at the top of the drive sleeve, the top of the helical groove and the longitudinal groove are connected by an annular groove, and a motor is coaxially connected to the bottom of the drive sleeve.
[0016] The principle and beneficial effects of this technical solution:
[0017] (1) The fixation frame provided in this invention can be used with the control component to fix the patient's arm. At the same time, it can be used with the fixation component to fix the patient's palm, so that the patient can maintain the hand posture for a long time during radial artery puncture to stabilize the radial artery puncture. When the fixation frame is used to fix the patient's arm, the two first screws are rotated in opposite directions. Since the moving frame is passed through the first screw, rotating the first screw can drive the two moving frames to move along the gap of the crossbar. When the moving frame moves, it will drive the drive shaft fixedly connected to the top of the moving frame to move synchronously. Since the drive shaft is hinged to the first swing arm and the second swing arm at the same time, the movement of the drive shaft will pull the fixation frame rotatably connected to one end of the first swing arm and the second swing arm to move down. The fastening strap will move towards each other and gradually clamp the patient's arm to fix the patient's arm.
[0018] (2) The auxiliary component provided in this invention can test the optimal puncture direction of the radial artery of the patient. When using the auxiliary component to determine the extension direction of the radial artery of the patient, the position of the drive sleeve is adjusted by the motor so that the longitudinal groove on the drive sleeve is aligned with the sliding button connected to the outside of the longitudinal rod in the vertical direction. Then the length of the telescopic rod is adjusted so that the connecting arm fixedly connected to the top of the telescopic rod drives the test plate fixedly connected to the bottom of the turntable to move down. The extension direction of the radial artery is tested by the sensor contact point set at the bottom of the test plate, thereby guiding the medical staff in the puncture direction.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:
[0026] Example:
[0027] like Figures 1 to 5As shown, the present invention provides a cardiology puncture auxiliary positioning device, including two pairs of fixation frames 12, which are arranged opposite to each other. The pair of fixation frames 12 at the upper end are connected by a connecting rod 3, and the other pair of fixation frames 12 are respectively fixedly connected to both sides of the extension plate 1. The bottom end of the fixation frame 12 is provided with multiple slots 9, and a connecting plate 10 is slidably locked in each slot 9. The two connecting plates 10 in opposite positions are connected by fastening straps 11, and the fastening straps 11 connected to the two pairs of fixation frames 12 are staggered in the horizontal direction.
[0028] like Figure 1 , Figure 2 and Figure 5 As shown, a plurality of fixed shafts 35 are fixedly connected to one end of the fixed frame 1 away from the extension plate 1. Two pairs of fixed shafts 35 are respectively rotatably connected to a pair of first swing rods 4 and a pair of second swing rods 5. The free ends of the first swing rods 4 and the second swing rods 5 are hinged. A control component is provided at one end of the extension plate 1.
[0029] like Figure 1 and Figure 5 As shown, the control assembly includes two pairs of crossbars 38 fixedly connected to both sides of the extension plate 1, and two first screws 39 rotatably connected between the two pairs of crossbars 38, with the two first screws 39 coaxially connected.
[0030] like Figure 2 and Figure 5 As shown, a movable frame 37 is mounted on the first screw 39. The two movable frames 37 are slidably locked between the two pairs of crossbars 38. A drive shaft 36 is fixedly connected to the top of the movable frame 37. The drive shaft 36 is simultaneously hinged to the first swing arm 4 and the second swing arm 5.
[0031] like Figure 1 and Figure 4 As shown, a fixing component is provided at the end of the extension plate 1 away from the control component. The fixing component includes a telescopic pad 21 that is slidably connected to the extension plate 1. A connecting seat 20 is fixedly connected to the top of the telescopic pad 21. A fixing ring 17 is hinged to the top of the connecting seat 20. Guide grooves 18 are provided on both sides of the fixing ring 17.
[0032] like Figure 4 As shown, a pressure frame 22 is slidably mounted in the guide groove 18, and a second screw 16 is rotatably mounted in the guide groove 18. The pressure frame 22 passes through the second screw 16, and the axis of the second screw 16 is parallel to the guide groove 18. A finger ring is provided at the free end of the pressure frame 22.
[0033] like Figure 1 and Figure 4 As shown, an auxiliary component is provided on the extension plate 1. The auxiliary component includes a connecting arm 27 fixedly connected to the top of the telescopic rod 33. The free end of the connecting arm 27 is rotatably fitted with a turntable 13. The bottom end of the turntable 13 is fixedly connected to a test plate 14.
[0034] like Figure 4 As shown, the test board 14 has multiple sensor contacts 15 at its bottom. The sensor contacts 15 can detect the line with the strongest vibration. The test board 14 has a guide window 24. Multiple lasers are arranged inside the guide window 24. The direction of the laser beam is the same as the direction of the line measured by the sensor contacts 15.
[0035] like Figure 4 As shown, a control button 23 is eccentrically connected to the top of the turntable 13, and a drive rod 26 is sleeved on the outside of the control button 23. A vertical rod 28 is fixedly connected to the bottom of the drive rod 26.
[0036] like Figure 1 and Figure 4 As shown, a sliding button 29 is connected to the outside of the longitudinal rod 28, and a drive sleeve 34 is fixedly connected to the extension plate 1. The top of the drive sleeve 34 is provided with a helical groove 32 and a longitudinal groove 30. The tops of the helical groove 32 and the longitudinal groove 30 are connected by an annular groove 31. A motor is coaxially connected to the bottom of the drive sleeve 34.
[0037] The auxiliary component can test the optimal puncture direction of the radial artery. When using the auxiliary component to determine the extension direction of the radial artery, the position of the drive sleeve 34 is adjusted by the motor so that the longitudinal groove 30 on the drive sleeve 34 is aligned vertically with the sliding button 29 connected to the outside of the longitudinal rod 28. Then, the length of the telescopic rod 33 is adjusted so that the connecting arm 27 fixedly connected to the top of the telescopic rod 33 drives the test plate 141 fixedly connected to the bottom of the turntable 13 to move downward. The extension direction of the radial artery is tested through the sensor contact 15 set at the bottom of the test plate 141. The laser direction set inside the guide window 24 will change synchronously according to the test direction of the sensor contact 15. Then, the turntable 13 and the test plate 141 are reset first. Then, the motor rotates the drive sleeve 34, so that the sliding button 29 slides along the annular groove 31 into the spiral groove. Then, the telescopic rod 33 pulls down the vertical rod 28. The sliding button 29 set outside the vertical rod 28 will slide along the spiral groove 32, thereby rotating the drive rod 26. The rotation of the drive rod 26 drives the turntable 13 where the control button 23 is located to rotate 180 degrees, thereby guiding the medical staff in the puncture direction.
[0038] The specific usage and function of this embodiment are as follows:
[0039] The fixation frame 12 in this invention can be used in conjunction with the control component to fix the patient's arm. Simultaneously, when used with the fixation component, it can also fix the patient's palm, facilitating prolonged hand positioning for stable radial artery puncture. When using the fixation frame 12 to fix the patient's arm, rotating the two first screws (which rotate in opposite directions) causes the two movable frames 37, which are mounted on the first screws, to translate along the gap in the crossbar 38. This translation of the movable frames 37 synchronously moves the two movable frames 38. The drive shaft 36, which is fixedly connected to the top of the 7th rod, moves synchronously. Since the drive shaft 36 is simultaneously hinged to the first swing arm 4 and the second swing arm 5, the movement of the drive shaft 36 will pull the fixed frame 12, which is rotatably connected to one end of the first swing arm 4 and the second swing arm 5, downward, so that the distance between the two relatively fixed frames 12 is shortened. Since the connecting plates 101, which are slidably locked at the bottom of the fixed frame 12 through the slot 9, are connected by fastening straps 11, and the fastening straps 11 are staggered along the horizontal direction, the fastening straps 11 will gradually clamp the patient's arm to fix the patient's arm when they move towards each other.
[0040] When using the fixation assembly to fix the patient's hand posture, first adjust the position of the fixing ring 17 through the telescopic pad 21 and the connecting seat 20. Then, have the patient insert their fingers into the fixing ring 17 and adjust the position of the pressure frame 22 according to the position of the patient's thumb. The patient's thumb is fixed by the finger ring set at the free end of the pressure frame 22. When the position of the pressure frame 22 needs to be adjusted, rotate the second screw 16. Since the pressure frame 22 is inserted through the second screw 16, the rotation of the second screw 16 will drive the pressure frame 22 to slide along the guide groove 18, thereby changing the position of the finger ring at the free end of the pressure frame 22.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of the present invention, and these should also be considered within the scope of protection of the present invention.
