Description

Technical Field

[0001] The present application belongs to the field of medical devices, and specifically relates to a device for detecting the puncture force of an atrial septal puncture needle. Background Art

[0002] In the current market environment, the puncture force detection method is mainly to test by measuring the puncture force of the puncture needle piercing the oval fossa of the pig heart. Although this method has certain feasibility, it has some significant problems, such as complex operation, poor repeatability and being affected by multiple factors.

[0003] The complexity of the puncture force test operation is mainly due to the fact that the process of puncturing the oval fossa of the pig heart with a puncture needle requires professional skills and experience, otherwise errors are prone to occur. This requires the testers to undergo special training, which makes the operation process complicated. In addition, since the puncture process involves the physical properties and physiological structure of biological tissues, different testers may obtain different results even under the same operating conditions, which leads to the problem of poor repeatability of puncture force testing.

[0004] Secondly, the results of puncture force detection will be affected by many factors. For example, changes in pressure during puncture, changes in puncture speed, and the physiological state of the pig heart may affect the accuracy of the test results. This requires strict manual control of these factors during the test process to ensure the reliability of the test results. However, the current puncture force detection method's control of internal or external factors depends on the professionalism of the tester, and in the process of repeated testing, it is inevitable that a certain range of human-caused random errors will occur, which reduces the accuracy of puncture force detection.

[0042] The following embodiments of the present application are only used to illustrate the specific embodiments of the present application, and these embodiments cannot be understood as limiting the present application. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present application are deemed to be equivalent replacement methods and fall within the scope of protection of the present application.

[0043] Those skilled in the art should understand that, in the disclosure of the present application, the terms "first", "second", "third", "fourth", "fifth", etc. are only used to distinguish different structures, but do not limit the number, connection relationship, etc. of specific structures; in addition, the directions or positional relationships indicated by "longitudinal", "transverse", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limitations on the present application.

[0044] The present application provides a device for detecting the puncture force of an atrial septal puncture needle. Figure 1 As shown, it includes a power module, a material fixing module, a detection module and a puncture needle fixing module.

[0045] The power module includes a fixed end 1 and a moving end 2, wherein the moving end can move relative to the fixed end (specifically, Figure 1As shown, the moving end can move up and down relative to the fixed end); the moving end 2 is directly or indirectly connected to the material fixing module (specifically, in this embodiment, a detection module 3 is provided between the moving end 2 and the material fixing module, that is, the moving end 2 is indirectly connected to the material fixing module through the detection module 3). When the moving end 2 moves, it can drive the material fixing module 5 to move together, especially when driving the material fixing module to move downward at a constant speed, so that the punctured material and the puncture needle are close to and in contact, avoiding the fluctuation of the puncture force caused by the non-constant force application speed during the puncture process, and providing stability of the puncture process. The material fixing module is used to fix the punctured material. When the punctured material contacts the puncture needle, it will not be displaced or change the angle in the non-moving direction due to the resistance of the puncture needle, preventing the fluctuation of the puncture force due to uneven force during the puncture process, further improving the stability of the puncture process, and ensuring the accuracy of puncture force detection.

[0046] When the material fixing module is driven by the moving end 2 to move downward, it approaches and reaches the position of the puncture needle, and the puncture material fixed by it contacts the puncture needle until it is punctured. In the process from contact to puncture of the puncture material, the material fixing module is subjected to resistance from the puncture needle. The detection module 3 can continuously detect the resistance of the material fixing module from the puncture needle to achieve continuous detection of the puncture force.

[0047] The puncture needle fixing module is arranged opposite to the material fixing module. When the material fixing module moves close to the puncture needle fixing module, during the contact between the puncture needle and the punctured material, the puncture needle fixing module can fix the puncture needle so that the puncture needle does not move or change its angle due to the reaction force of the punctured material, thereby preventing the puncture force from fluctuating due to uneven force application during the puncture process, thereby ensuring the accuracy of puncture force detection.

[0048] The power module may be a cylinder, a hydraulic cylinder or an electric push rod. Specifically, in this embodiment, the power module is a cylinder, in which case the fixed end 1 is the cylinder body of the cylinder, and the moving end 2 is the piston rod of the cylinder.

[0049] Regarding the detection module 3, the present application has no specific restrictions, as long as the detection module can detect the resistance of the material fixing module when the moving end drives the material fixing module to move. Figure 1As shown, in this embodiment, the detection module 3 is a pressure sensor, which is arranged between the moving end 2 and the material fixing module for detection. More specifically, one end of the pressure sensor is connected and fixed to the material fixing module at the contact surface by screws; after the material fixing module is subjected to the resistance of the puncture needle, the resistance is directly transmitted to the pressure sensor through the material fixing module, and the pressure sensor reflects the magnitude of the resistance, thereby determining the magnitude of the puncture force.

[0050] Regarding the punctured material, artificial skin can be selected to ensure the repeatability of the test and the comparability between the puncture force test results of different puncture needles.

[0051] In one embodiment, the material fixing module includes a first fixing unit 4 and a material fixing unit 5 .

[0052] like Figure 1 As shown, the material fixing unit 5 is used to fix the punctured material, and the first fixing unit 4 is directly or indirectly fixedly connected to the moving end 2 to fix the material fixing unit 5.

[0053] The structure of the first fixing unit 4 is as follows Figure 2As shown, the first protruding end 41 and the first bolt 42, the first fixing unit 4 is directly or indirectly fixedly connected to the moving end 2, specifically, the first fixing unit 4 is connected and fixed to the moving end 2 at the contact surface by screws; the first fixing unit 4 is C-shaped, and its two ends are a pair of first protruding ends 41 extending downward, and the distance between the pair of first protruding ends 41 is slightly larger than the size of the material fixing unit 5, so that the material fixing unit 5 can be embedded between the first protruding ends 41, so as to be fixed by the first protruding ends 41; the pair of first protruding ends 41 are respectively Relative threaded through holes are provided, and a pair of first bolts 42 are relatively provided at the position where the first protruding end 41 has the threaded through hole, and the pair of first bolts 42 can be screwed into / out of the threaded through holes of the first protruding end 41 respectively; when the material fixing unit 5 is embedded between the pair of first protruding ends 41, the pair of first bolts 42 are respectively screwed into the threaded through holes of the first protruding end 41, so that the material fixing unit 5 is clamped by the first bolts 42 screwed in opposite directions, so as to fix the position of the material fixing unit 5 relative to the first protruding end 41, so that the punctured material is in contact with the puncture needle. When the material fixing unit 5 is touched, the material fixing unit 5 does not move or change its angle due to the resistance of the puncture needle, thereby maintaining the accuracy of the puncture force detection; when the material fixing unit 5 is clamped by a pair of the first bolts 42, the first bolts 42 are respectively screwed out a certain distance to reduce the clamping force on the material fixing unit 5 and break away from the complete fixation relative to the first protruding end 41. Therefore, the operator can adjust the angle of the material fixing unit 5 to control the angle between the punctured material and the puncture needle, thereby realizing the detection of the puncture force at different puncture angles, further improving the detection accuracy. The flexibility enables the operator to simulate puncture scenarios at different angles; in addition, after adjusting the material fixing unit 5 to a fixed angle, the first bolts 42 are screwed in again for a certain distance to increase the clamping force on the material fixing unit 5 and to be completely relatively fixed between the first protruding ends 41, so that the punctured material will not be displaced in a non-moving direction or change in angle due to the resistance of the puncture needle when contacting the puncture needle at different angles, thereby eliminating the influence of external factors on the puncture experiment and ensuring the repeatability of the experiment and the accuracy of the detection.

[0054] In one embodiment, the material fixing unit 5 includes a pair of layers, which are stacked and detachably connected at the contact surface by screws. The center of the pair of layers is provided with an opening 51, and when the pair of layers are stacked and fixed to each other, the two openings 51 completely overlap. Before fixing the pair of layers, the material to be punctured is laid flat on the upper surface of the lower layer, and then the lower surface of the upper layer is stacked on the material to be punctured. After the layers are fixed by screws, the material to be punctured is completely fixed between the two layers, and the central part thereof is exposed at the opening 51, which can be in direct contact with the puncture needle, so that the material to be punctured is punctured in a completely fixed state, thereby improving the accuracy of puncture detection. Specifically, when the material fixing unit 5 moves downward to the position of the puncture needle, the puncture material can directly contact the puncture needle at the opening 51 until it is punctured; when the punctured material contacts the puncture needle, the resistance of the puncture needle is transmitted to the detection module 3 directly or indirectly connected to the material fixing module through the interaction of the various parts of the material fixing module, so as to realize resistance detection. Specifically, the material fixing unit 5 forms a 90° angle with the first protruding end 41, that is, the material fixing unit 5 is perpendicular to the first protruding end 41 and is fixed between the first protruding ends 41. The puncture needle contacts the punctured material and applies resistance to the punctured material. The resistance of the first bolt 42, the first bolt 42, the first protruding end 41, and the first protruding end 41 is transmitted upward and evenly distributed to a pair of first protruding ends 41. Finally, the resistance is transmitted to the detection module 3 with the same magnitude and direction. The detection module 3 detects the magnitude of the resistance, that is, the magnitude of the puncture force is obtained. Through this connection method, the operator can perform repeated and accurate detection of the puncture force in a simple and flexible operating environment, avoiding problems such as complicated operation, difficult to control errors, and poor repeatability, and providing an efficient and convenient solution for puncture force detection.

[0055] In one embodiment, the projection of the material fixing unit 5 on the plane where the punctured material is located is a circle or a regular n-gon, where n is greater than or equal to 3. The material fixing unit 5 can adapt to carrying punctured materials of different shapes while maintaining a small space occupancy; the shape of the surface opposite to the first protruding end 41 and the material fixing unit 5 is a shape that can adapt to the embedding of the material fixing unit 5. In a specific embodiment, the projection of the material fixing unit 5 on the plane where the punctured material is located is a rectangle, and the surface opposite to the first protruding end 41 and the material fixing unit 5 is a plane, so that the material fixing unit 5 is embedded between the first protruding ends 41; in another specific embodiment, the projection of the material fixing unit 5 on the plane where the punctured material is located is a circle, and the surface opposite to the first protruding end 41 and the material fixing unit 5 is a curved surface, so that the material fixing unit 5 is embedded between the first protruding ends 41. Therefore, when the material fixing unit 5 is not fixed by the first bolt 42, the material fixing unit 5 can rotate freely along the straight line connecting a pair of the first bolts 42 as the axis, providing the operator with the function of freely adjusting the puncture angle and realizing flexible adjustment of the puncture parameters.

[0056] In one embodiment, the puncture needle fixing module includes a second fixing unit 6 and a puncture needle fixing unit 7. Figure 1 As shown, the puncture needle fixing unit 7 is used to fix the puncture needle, and the second fixing unit 6 can fix the puncture needle fixing unit 7 .

[0057] Specifically, the structure of the second fixing unit 6 is as follows: Figure 3As shown, it includes a second protruding end 61 and a second bolt 62, and the distance between the second protruding end 61 and the second protruding end 61 is slightly larger than the size of the puncture needle fixing unit 7, so that the puncture needle fixing unit 7 can be embedded between the second protruding ends 61, so as to be fixed by the second protruding end 61; one end of the pair of second protruding ends 61 is provided with a threaded through hole, and a pair of second bolts 62 are relatively provided at the position where the second protruding end 61 has the threaded through hole, and the pair of second bolts 62 can be screwed into / out of the threaded through hole of the second protruding end 61 respectively; when the puncture needle fixing unit 7 is embedded between the pair of second protruding ends 61, the pair of second bolts 62 are respectively screwed into the threaded through holes of the second protruding end 61, so that the puncture needle fixing unit 7 is clamped by the second bolts 62 screwed in oppositely, so as to fix the position of the puncture needle fixing unit 7 relative to the second protruding end 61, so that when the puncture needle contacts the punctured material, the puncture needle fixing unit 7 does not move or be displaced due to the reaction force of the punctured material. The angle changes to maintain the accuracy of puncture force detection; when the puncture needle fixing unit 7 is clamped by a pair of second bolts 62, the second bolts 62 are respectively screwed out a certain distance to reduce the clamping force on the puncture needle fixing unit 7 and break away from the complete fixation relative to the second protruding end 61, so that the operator can adjust the angle of the puncture needle fixing unit 7 to control the angle of the puncture needle, and realize the detection of puncture force at different puncture angles, further improving the flexibility of detection, so that the operator can simulate puncture scenarios at different angles; in addition, after adjusting the puncture needle fixing unit 7 to a fixed angle, the second bolts 62 are respectively screwed in a certain distance again to increase the clamping force on the puncture needle fixing unit 7 and completely fix it relative to the second protruding end 61, so that the puncture needle does not move or change its angle due to the reaction force of the puncture material when it contacts the punctured material at different angles, which can eliminate the influence of external factors on the puncture experiment and ensure the repeatability of the experiment and the accuracy of detection.

[0058] In one embodiment, the puncture needle fixing unit 7 is a cartridge 71, and a through hole 72 is provided at the center of the cartridge 71, through which the puncture needle passes through the cartridge 71; by rotating the cartridge 71, the inner diameter of the through hole 72 is reduced until the through hole completely wraps the part of the puncture needle in the through hole 72, so as to completely fix the puncture needle. The cartridge 71 of the present application is preferably a cartridge 71 with a through hole inner diameter close to the diameter of the puncture needle, so as to adapt to the passage and / or fixation of the puncture needle in the through hole 72.

[0059] In one embodiment, the atrial septal puncture needle puncture force detection device further includes a control module 10, such as Figure 4As shown, the control module 10 includes a control unit 100 , an input unit 101 , an output unit 102 and an execution unit 103 .

[0060] The control unit 100 can be electrically connected to the input unit 101 and the execution unit 103 respectively, and the input unit 101 is used to input electrical signals to the control unit 100; the control unit 100 can receive and process control request signals, generate control signals, and send control signals to the execution unit 103 to control the action of the power module through the execution unit 103.

[0061] The control unit 100 can be electrically connected to the detection module 3 and the output unit 102 respectively. When the device performs puncture force detection, the detection module can input the electrical signal corresponding to the detection result into the control unit 100, and the control unit 100 processes the electrical signal and outputs the detection result through the output unit 102.

[0062] The control unit 100 may be a single chip microcomputer, a PLC or the like.

[0063] The input unit 101 may be a button, a touch screen, or the like.

[0064] Regarding the execution unit 103, when the power module is a pneumatic cylinder / hydraulic cylinder, the execution unit 103 can be exemplified as a solenoid valve; when the power module is an electric push rod, the execution unit 103 can be exemplified as a frequency converter, etc.

[0065] The output unit 102 may be a display screen, a speaker, or the like.

[0066] Those skilled in the art can know that the touch screen can be used as both the input unit 101 and the output unit 102 in the present application.

[0067] More specifically, when the power module is a cylinder, the execution unit 103 is a solenoid valve, and the input unit is a button, the button can be pressed, and the control unit receives the electrical signal input by the button to control the movement of the piston rod of the cylinder through the solenoid valve, thereby starting the puncture force detection. In particular, when two buttons are provided, and the two buttons jointly control the start and stop of the detection device, the distance between the two buttons can be set to be greater than the distance that can be controlled by a single palm (such as greater than 20 cm), so that the operator needs to press the two control buttons with both hands at the same time to start and stop the device for puncture force detection, thereby preventing one hand from adjusting the puncture needle fixing module, etc., while the other hand starts the device, causing an accident.

[0068] In addition, when the input unit 101 includes a touch screen and / or buttons, it can be further realized that the speed, depth and other parameters of the puncture can be adjusted through the control module 10, which has the characteristics of easy use, flexible operation and high degree of automation. It not only improves the experimental efficiency of the operator and maintains the accuracy of the puncture force detection, but also lowers the operational threshold of the puncture force detection, and provides a feasible solution for promoting and popularizing the puncture force detection method.

[0069] In one embodiment, the atrial septal puncture needle puncture force detection device of the present application further includes a frame, and the frame is used to set at least one of the power module, the puncture needle fixing module and the control module 10. Specifically, the frame includes a bracket 8 and a base 9, such as Figure 1 As shown, the fixed end 1 of the power module and the bracket 8 are fixed to each other by setting screws on the contact surface, so that the power module and the material fixing module directly or indirectly connected thereto are suspended; the second fixing unit 6 is connected and fixed to the base 9, so that the puncture needle fixing module is fixed as a whole under the material fixing module; by respectively setting the material fixing module and the puncture needle fixing module on the bracket 8 and the base 9, the puncture force detection process is made more stable, and at the same time, a load is provided for the atrial septum puncture needle puncture force detection device, which is convenient for the storage and maintenance of the device.

[0070] In one embodiment, the rack can also accommodate the control unit 10 to achieve two-way protection for the operator and the control unit 10. Specifically, the execution unit 103 of the control unit 10 is connected to the power module inside the bracket 8 and the base 9 to avoid the influence of external factors on the connection between the execution unit 103 and the power module; the output unit 102 of the control unit 10 is fixed to the bracket 8 or the base 9 by screws, and the operator can observe the puncture force value in real time without affecting the experimental process, so as to facilitate fault judgment and subsequent puncture force recording.

[0071] Although the embodiments of the present application are described above in conjunction with the accompanying drawings, the present application is not limited to the above specific embodiments and application fields, and the above specific embodiments are merely illustrative and instructive, rather than restrictive. A person of ordinary skill in the art can also make many forms under the guidance of this specification and without departing from the scope of protection of the claims of the present application, all of which belong to the protection of the present application.
