Description

Technical Field

[0001] The invention belongs to the technical field of medical puncture equipment, and in particular relates to a clinical puncture device for cardiology. Background Art

[0002] Cardiology, also known as cardiovascular medicine, is a clinical department set up in the general internal medicine departments of hospitals at all levels for the diagnosis and treatment of cardiovascular diseases. The diseases treated include angina pectoris, hypertension, sudden death, arrhythmia, heart failure, premature beats, irregular heartbeat, myocardial infarction, cardiomyopathy, myocarditis, acute myocardial infarction and other cardiovascular diseases.

[0003] In the field of cardiology, pericardial effusion is a common clinical manifestation and one of the key signs of pericardial disease. It can be seen in exudative pericarditis and other non-inflammatory pericardial lesions. When the course of the disease lasts for more than a few months, it develops into chronic pericardial effusion. If not intervened in time, pericardial effusion will cause heart failure, which is life-threatening in severe cases. Therefore, cardiology often uses puncture to extract the patient's pericardial effusion. Through suction or drainage, it can quickly relieve the symptoms of cardiac tamponade, or obtain pericardial fluid, thereby achieving the purpose of treatment, and also helps clinical diagnosis, such as a cardiology clinical puncture device proposed in the patent announcement number CN113768592B.

[0004] At present, pericardial effusion puncture mainly relies on manual operation by doctors, which requires extremely high proficiency and experience level of doctors, resulting in a limited number of doctors who can do this job. Due to the differences in chest wall tissues of different patients, patients with well-developed chest wall muscles or tough tissues have significantly increased resistance during puncture. When the doctor punctures too fast and the puncture needle encounters resistance, the lateral force generated by the resistance will cause the puncture needle to deviate from the predetermined path, and the faster the speed, the more obvious the deviation caused by the lateral force, which seriously affects the accuracy of the puncture. Manual operation is extremely difficult to control the puncture speed and accuracy. Doctors who can perfectly perform this job are scarce, and it is difficult to meet actual clinical needs. Summary of the invention

[0005] The purpose of the present invention is to provide a clinical puncture device for cardiology in view of the above problems.

[0006] To achieve the above object, the present invention adopts the following technical solution: A clinical puncture device for cardiology, comprising a support plate, and also comprising:

The positioning plates and the puncture shell are rotatably connected through a rotating shaft. A binding band is fixedly installed on the positioning plates. Annular fixing plates sleeved outside the rotating shaft are fixedly installed on the opposite sides of the lower end of the puncture shell. A plurality of tightening bolts corresponding to the annular fixing plates are threadedly connected to the side wall of the positioning plates.

[0016] In the above-mentioned clinical puncture device for cardiology, the real-time monitoring and feedback mechanism for puncture resistance includes two anti-detachment rods symmetrically and fixedly installed on the upper end of the fixing frame. The upper ends of the anti-detachment rods penetrate through the upper end of the lifting plate and are fixedly connected with anti-detachment plates. A pressure sensor is fixedly installed at the lower end of the lifting plate. The lower end input end of the pressure sensor is in contact with the upper end of the fixing frame.

[0017] In the above-mentioned clinical puncture device for cardiology department, the liquid accumulation extraction power supply mechanism includes a mounting bracket fixedly installed at the upper end of the support plate. An electric push rod is fixedly installed inside the mounting bracket. The upper mobile end of the electric push rod is fixedly connected to a rotating motor. The upper output end of the rotating motor is fixedly connected to a rotating plate. Suction syringes are fixedly inserted on both sides of the upper end of the rotating plate. An extension bracket located below one of the suction syringes is also fixedly installed at the upper end of the support plate. A connecting cylinder that is hermetically sleeved with the lower suction end of the suction syringe is fixedly inserted at the upper end of the extension bracket. One end of the suction pipe away from the buffer cylinder is fixedly communicated with the lower end of the connecting cylinder.

[0018] In the above-mentioned clinical puncture device for cardiology department, the reciprocating drive mechanism includes a U-shaped limit plate fixedly installed at the upper end of the rotating plate. Two reciprocating lead screws are symmetrically rotatably connected to the lower end of the horizontal part of the U-shaped limit plate and the upper end of the rotating plate. A threaded hole that is threadedly sleeved with the reciprocating lead screw is opened at the mobile end of the suction syringe. A second bidirectional motor assembly for driving the two reciprocating lead screws to rotate self is also fixedly installed at the upper end of the U-shaped limit plate.

[0019] In the above-mentioned clinical puncture device for cardiology department, the transverse part of the positioning plate is set as an arc structure, and an anti-slip silica gel pad is fixedly connected to the inner side of the positioning plate.

[0020] Compared with the existing technology, the beneficial effects of the present invention are as follows:

[0021] 1. By setting the automatic puncture mechanism, the hanging and placing mechanism, and the positioning and locking mechanism, a more stable puncture action can be provided, ensuring the stability and safety of the puncture. Moreover, a stable positioning position can be provided according to the puncture requirements, ensuring the smoothness during the puncture process. The puncture angle can be quickly adjusted as needed and will not shift during the puncture process, avoiding the problem that improper puncture angle may cause damage to blood vessels, effectively improving the puncture quality and efficiency, and having lower requirements for the level of operators, greatly increasing the number of medical staff who can perform puncture operations, and better meeting the treatment needs.

[0022] 2. By means of the puncture resistance real-time monitoring and feedback mechanism and the automatic puncture mechanism provided, it is possible to automatically adjust the puncture speed based on the different resistances encountered during the puncture process, so that the greater the puncture resistance, the slower the puncture speed. This can avoid the problem that when encountering a large resistance and still maintaining a fast puncture speed, the puncture needle will forcibly penetrate the body tissue, thus causing unnecessary damage. Moreover, it can avoid the problem that when the puncture speed is too fast and encounters resistance, the puncture needle is likely to deviate from the predetermined puncture path, thereby affecting the puncture accuracy, effectively improving the puncture quality.

[0023] 3. By means of the effusion extraction power supply mechanism and the reciprocating drive mechanism provided, it is possible to provide a relatively continuous pericardial effusion extraction action, and there is no need for medical staff to intervene in the operation, effectively improving the effusion extraction efficiency, and releasing more medical labor force, ensuring the continuous and stable operation of the pericardial effusion extraction work, shortening the time for puncturing and extracting the effusion, and avoiding the problem that too long operation will increase the patient's pain and infection risk.

The puncture resistance real-time monitoring and feedback mechanism 5 includes two anti-detachment rods 51 symmetrically and fixedly installed on the upper end of the fixing frame 25. The upper ends of the anti-detachment rods 51 penetrate through the upper end of the lifting plate 24 and are fixedly connected with anti-detachment plates 52. A pressure sensor 53 is fixedly installed at the lower end of the lifting plate 24. The lower input end of the pressure sensor 53 abuts against and is connected to the upper end of the fixing frame 25.

[0038] The liquid accumulation extraction power supply mechanism 6 is installed on one side of the upper end of the support plate 1 and is communicated with the automatic puncture mechanism 2. The liquid accumulation extraction power supply mechanism 6 includes an installation bracket 61 fixedly installed on the upper end of the support plate 1. An electric push rod 62 is fixedly installed inside the installation bracket 61. The upper moving end of the electric push rod 62 is fixedly connected with a rotating motor 63. The upper output end of the rotating motor 63 is fixedly connected with a rotating plate 64. Two suction syringes 65 are fixedly inserted on both sides of the upper end of the rotating plate 64. An extension bracket 66 located below one of the suction syringes 65 is also fixedly installed on the upper end of the support plate 1. A connecting cylinder 67 that is hermetically sleeved with the lower suction end of the suction syringe 65 is fixedly inserted at the upper end of the extension bracket 66. One end of the suction pipe 28 far from the buffer cylinder 26 is fixedly communicated with the lower end of the connecting cylinder 67. An electromagnetic valve 68 is also installed on the pipe wall of the suction pipe 28 near the connecting cylinder 67. A liquid collection tank 69 corresponding to the position of the other suction syringe 65 is also embedded on the upper end of the support plate 1. A reciprocating driving mechanism 7 for driving the moving ends of the two suction syringes 65 to make reciprocating lifting movements is also fixedly installed on the upper end of the rotating plate 64.

[0039] The reciprocating drive mechanism 7 includes a U-shaped limit plate 71 fixedly installed at the upper end of the rotating plate 64. Two reciprocating lead screws 72 are symmetrically and rotatably connected to the lower end of the horizontal part of the U-shaped limit plate 71 and the upper end of the rotating plate 64. A threaded hole for threadedly sleeving the reciprocating lead screw 72 is formed in the moving end of the suction syringe 65. A second bidirectional motor assembly 73 for driving the two reciprocating lead screws 72 to rotate is fixedly installed at the upper end of the U-shaped limit plate 71.

[0040] The PLC control panel 8 is fixedly installed at the upper end of the support plate 1 and is electrically connected to the automatic puncture mechanism 2, the puncture resistance real-time monitoring and feedback mechanism 5, and the power supply mechanism 6 for extracting the effusion. A warning device 9 is also fixedly installed at the upper end of the PLC control panel 8.

[0041] The operating principle of the present invention is described as follows: Place the positioning plate 41 on the body part of the patient that needs to be punctured, and then fix the positioning plate 41 and the automatic puncture mechanism 2 through the strap 43. According to the requirement of the puncture angle, use the rotational connection function of the rotating shaft 42 between the automatic puncture mechanism 2 and the positioning plate 41 to adjust the placement angle of the puncture shell 21, thereby changing the puncture angle of the puncture needle 27. After the adjustment is completed, rotate and tighten the bolt 45 so that the end of the bolt 45 abuts and presses against the annular fixing plate 44 to firmly fix the automatically adjusted puncture mechanism 2.

[0042] The first bidirectional motor assembly 23 is controlled to operate by the PLC control panel 8. The first bidirectional motor assembly 23 drives two rotating screws 22 to rotate synchronously. Then, through the threaded socket connection between the rotating screws 22 and the lifting plate 24, the lifting plate 24 drives the fixing frame 25, the buffer cylinder 26, and the puncture needle 27 to move downward and extend out of the bottom of the puncture shell 21, and perform puncture work on the puncture body position of the patient. When the puncture needle 27 enters the skin, the working power of the first bidirectional motor assembly 23 is controlled so that the puncture needle 27 advances at a speed of 1-2 millimeters per second. The resistance received by the puncture needle 27 during the puncture process is fed back to the pressure sensor 53 on the lower side of the lifting plate 24 through the buffer cylinder 26 and the fixing frame 25. The pressure value received by the pressure sensor 53 is the puncture resistance received by the puncture needle 27. The PLC control panel 8 automatically adjusts the working power of the first bidirectional motor assembly 23 based on the puncture resistance, and then automatically regulates the puncture speed. Specifically, as the puncture needle 27 penetrates deeper, if it encounters gradually increasing resistance, such as hitting muscle or fascia tissue, the speed should be further reduced, and the speed can be reduced to 0.5-1 millimeter per second. When the puncture needle 27 approaches the target site such as the pericardial cavity, the resistance will suddenly drop, showing a "falling feeling". At this time, the puncture speed is reduced to the slowest, and it is carefully advanced at a speed of 0.1-0.5 millimeter per second. During this process, if abnormal resistance is encountered during the approach to the target, such as the resistance suddenly increasing and not conforming to the normal situation, at this time, the PLC control panel 8 stops the needle insertion action and issues a warning through the warning device 9 to remind the medical staff accordingly, and re-evaluates the puncture path and the patient's condition to avoid the problem that forcibly breaking through the resistance may cause damage to the patient's body tissues;

[0043] Before the puncture operation, medical staff will use echocardiogram images to confirm the amount of pericardial effusion, the position and mobility of the heart, and then determine the puncture depth after the puncture needle 27 enters the pericardial cavity. Specifically, when the amount of pericardial effusion is large, in order to ensure sufficient aspiration of the effusion, the puncture needle 27 needs to penetrate appropriately. If the effusion is relatively localized, after the puncture needle 27 enters the pericardial cavity, the depth is adjusted according to the specific position and scope of the effusion under ultrasound guidance to ensure that the tip of the needle is in the central area of the effusion for effective aspiration. For example, when the effusion is mainly concentrated in the pericardial cavity in front of the heart, the puncture needle 27 can be slightly advanced after entering the pericardial cavity; there are individual differences in the position of each person's heart, some hearts are in a higher position, and some are relatively lower. For patients with a higher heart position, the depth of the puncture needle 27 continuing to enter the pericardial cavity should be relatively shallower to avoid damaging large blood vessels and other structures at the bottom of the heart. At the same time, the heart has a certain degree of mobility during the breathing process. After the puncture needle 27 enters the pericardial cavity, the movement of the heart needs to be considered to avoid the puncture needle 27 damaging the myocardium due to the beating of the heart. Generally, when the patient is breathing calmly, the safe depth of the puncture needle 27 is determined according to the approximate movement range of the heart, and a certain buffer space is usually reserved to prevent the heart from colliding with the puncture needle 27 during the movement process;

[0044] After determining the puncture depth of the puncture needle 27 entering the pericardial cavity, the distance change amount of the laser rangefinder 29 is pre-controlled through the PLC controller panel. Specifically, when the puncture needle 27 enters the pericardial cavity, at this time, the PLC control panel 8 controls the laser rangefinder 29 to work. When the laser rangefinder 29 monitors that the distance change from the lifting plate 24 reaches the preset threshold, the PLC control panel 8 controls the first bidirectional motor assembly 23 to stop operating, completing the confirmation of the puncture position. During this process, medical staff will use real-time monitoring means such as echocardiogram to determine the position and depth of the puncture needle 27. Ultrasound can clearly show the relationship between the puncture needle 27 and the heart, pericardium, and surrounding tissues. According to the information fed back by the ultrasound image, the doctor can accurately judge the depth of the puncture needle 27 continuing to enter the pericardial cavity to ensure that the puncture needle 27 is in a safe position and conducive to effusion aspiration. When encountering special problems, medical staff can control the continuous penetration action of the puncture needle 27 through the emergency brake switch 210 installed on the outer wall of the puncture shell 21 to ensure the safety and reliability of the puncture operation;

[0045] When the puncture position of the puncture needle 27 is confirmed, the PLC control panel 8 controls the second bidirectional motor assembly 73 to start working, and the second bidirectional motor assembly 73 drives the two reciprocating screws 72 to rotate synchronously, and then the threaded sleeve connection between the reciprocating screw 72 and the moving end of the suction syringe 65 makes the moving end of the suction syringe 65 move (the structure of the suction syringe 65 is the syringe structure in the existing medical equipment, and a piston is provided inside the syringe. The piston is driven to move by the push-pull rod to form a negative pressure suction force in the syringe). When the movable end of the suction syringe 65 moves upward, a negative pressure suction force is formed therein, and the sealing sleeve of the lower end of the suction syringe 65 and the connecting tube 67 cooperate with each other, and the suction tube 28 cooperates with the puncture needle 27 to quickly suck the pericardial effusion into the suction syringe 65. When the second bidirectional motor assembly 73 drives the movable end of the suction syringe 65 to move to the end, the PLC control panel 8 first controls the solenoid valve 68 on the suction tube 28 to close, and then controls the electric push rod 62 to push the rotating plate 64 upward, so as to push the two suction syringes 65 upward, so that the suction syringes 65 and the connecting tube 67 are connected. The bottom end of the suction syringe 65 connected to the sealing sleeve of the connecting tube 67 is separated from the connecting tube 67, and the PLC control panel 8 controls the rotating motor 63 to drive the rotating plate 64 to rotate 180 degrees, so that the suction syringe 65 full of pericardial effusion moves to the upper end of the liquid collecting tank 69, and the other empty suction syringe 65 moves to the upper end of the connecting tube 67. The PLC control panel 8 controls the electric push rod 62 to drive the rotating plate 64 to move downward, and the lower end liquid inlet of the empty suction syringe 65 is sealed and connected to the connecting tube 67 again, and the liquid is adsorbed. The lower end of the pericardial effusion suction syringe 65 is connected to the fluid collection tank 69 again. When the second bidirectional motor assembly 73 drives the reciprocating screw 72 to rotate again, the controlled suction syringe 65 performs the suction work of the pericardial effusion again. The suction syringe 65 full of pericardial effusion discharges the pericardial effusion into the fluid collection tank 69. According to the patient's physical condition and vital signs data, the medical staff independently confirms and controls the extraction volume of the pericardial effusion, and can also control the stop of the extraction work through the emergency brake switch 210 to ensure safety.
