Description

Technical Field

[0001] The utility model relates to the field of ultrasonic scalpel preparation, in particular to a testing device for conductive shrapnel in an ultrasonic scalpel. Background Art

[0002] Ultrasonic scalpel (also known as ultrasonic scalpel or ultrasonic hemostatic scalpel) is an advanced medical device widely used in surgical operations. Its working principle is based on high-frequency ultrasonic vibrations, which can accurately cut tissue and reduce bleeding at the same time. It is an indispensable tool in modern minimally invasive surgery. The core part of the ultrasonic scalpel is the transducer, which can convert electrical energy into mechanical energy and generate high-frequency vibrations (usually around 55,000 Hz). This high-frequency vibration is transmitted to the surgical site through a special blade head, allowing the blade head to cut tissue gently and precisely. The ultrasonic scalpel can not only cut tissue, but also has a coagulation function. During the cutting process, the high-frequency vibration of the blade head can close the blood vessels, thereby reducing bleeding.

[0003] During surgery, the surgeon needs to rotate the blade to accommodate different surgical positions. Since the blade and transducer are relatively fixed, the transducer also needs to rotate. Furthermore, the transducer requires continuous power during use. Therefore, in most existing ultrasonic scalpels, the power cord is directly connected to the transducer and hangs at the rear end of the handle. This often causes fatigue in the operator's hands and easily causes the power cord to become tangled, hindering surgical performance.

[0004] Based on the above problems, the applicant proposed to provide a conductive spring in the ultrasonic scalpel handle to cooperate with the conductive ring, so that the power cord can rotate independently of the transducer, thereby improving the operator's hand fatigue and avoiding problems such as power cord tangling. However, the conductive spring is generally thin and small. During the process of installing the conductive spring into the ultrasonic scalpel handle shell, it is easy to install the conductive spring in an inaccurate position, and the installation error cannot be directly observed with the naked eye. This makes it impossible to ensure the coordination between the conductive spring and the conductive ring at the rear of the transducer to ensure the stability of the electrical connection after the transducer is subsequently installed, affecting the overall quality of the scalpel.

[0037] See also Figure 1 The figure shows a schematic diagram of the overall structure of a test device according to a specific embodiment of the present invention for testing the installation position of a conductive spring in an ultrasonic surgical knife. The ultrasonic surgical knife includes a housing 1, a transducer assembly (not shown in the figure), and two sets of conductive springs 2.

During the subsequent assembly process of the ultrasonic surgical knife, a power connection connector (not shown in the figure) is provided on the housing 1 at the bottom of its handle for connecting to an external power cord and an external power source.

[0038] See also Figures 2 to 6 As shown, the test device 10 provided in this embodiment includes a shell 3, a conductive member 4 and a detection component. The conductive member 4 is fixed on the end of one side axis of the shell 3. The conductive member 4 has a first conductive part 41 and a second conductive part 42 that are insulated from each other.

[0044] The housing 3 specifically includes a cylinder 31 and a cover plate 32. The cylinder 31 has a through hole extending axially therethrough. The cover plate 32 is fixedly mounted on one axial end of the cylinder 31 and closes the through hole of the cylinder 31 on that side. The conductive member 4 is fixedly mounted on the outer axial end of the cover plate 32. Specifically, the first conductive portion 41 is annular, and the second conductive portion 42 is annular or disc-shaped. The first conductive portion 41 is arranged circumferentially outside the second conductive portion 42, and the axis of the first conductive portion 41 and the axis of the second conductive portion 42 both extend collinearly with the axis of the cylinder 31. The conductive member 4 is entirely sheet-shaped and, when provided, can be a metal sheet-shaped ring comprising the first conductive portion 41 and a metal sheet-shaped disc comprising the second conductive portion 42. The conductive member 4 is integrally embedded in the axial end of the cover plate 32, with the outer axial end surface of the conductive member 4 flush with the axial end surface of the cover plate 32.

[0045] See also Figure 6 As shown, the mounting seat 5 specifically includes a cover portion 53, a matching portion 52, and a mounting portion 51, which are sequentially connected along the axial direction. The outer diameter of the mounting portion 51 is smaller than the diameter of the through hole of the cylinder 31, and the matching portion 52 can be inserted into the through hole of the cylinder 31. The outer diameter of the cover portion 53 is larger than the diameter of the through hole of the cylinder 31, and the cover portion 53 abuts against one side axial end surface of the cylinder 31. The cylinder 31 is also provided with an annular limiting boss 31a. When specifically configured, the matching portion 52 and the through hole of the cylinder 31 form an interference fit. When the mounting seat 5 is axially inserted into the cylinder 31, the mounting connection with the cylinder 31 is completed.

[0046] Not shown, in an ultrasonic surgical knife, the transducer assembly includes a transducer housing, a conductive component disposed at one end of the transducer housing, and a transducer body disposed in the transducer housing, wherein the conductive component has an outer conductive portion and an inner conductive portion, and the outer conductive portion is annular and disposed circumferentially outside the inner conductive portion. When the transducer assembly is connected to the mounting structure 11 of the housing 1, the connection is mainly achieved through the cooperation between the transducer housing and the mounting structure 11, and the two sets of conductive springs 2 elastically contact the outer conductive portion 2 and the inner conductive portion 2 respectively. When the test device 10 is specifically set up, the structure of the housing 3 can be the same as that of the transducer housing.

[0047] Combine Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 As shown, after the two sets of conductive springs 2 are respectively installed on the housing 1, when the installation position of the two sets of conductive springs 2 is tested using the test device 10, the test device 10 is installed in the housing 1 so that the shell 3 is matched with the installation structure 11, and the two sets of conductive springs 2 are respectively against the end of the shaft on one side of the test device 10. Subsequently, a conductive element is used to electrically connect the other ends of the two sets of conductive springs 2 to make them connected. If the buzzer 7 sounds and / or the indicator light 8 is lit at this time, it means that Figure 8 The circuit shown is connected, and the installation position of the two sets of conductive springs 2 is correct; if the buzzer 7 does not sound and the indicator light 8 is not lit, it means that Figure 8 or Figure 9 The circuit shown is not connected, indicating that the installation position of one or two sets of conductive springs 2 is incorrect, and the test result is unqualified. In other embodiments, the internal circuit behind the conductive springs 2 in the housing 1 of the ultrasonic surgical knife can also be installed first. In this way, when testing the position of the conductive springs 2, the internal circuit corresponds to Figures 7 to 9The transformer T shown in the figure, that is, the two sets of conductive springs 2 are electrically connected. The test device 10 only needs to be installed in the housing 1 so that the shell 3 and the mounting structure 11 are matched, and the two sets of conductive springs 2 are respectively placed against the end of the shaft on one side of the test device 10. The test can be completed by observing whether the indicator light 8 is lit or the buzzer 7 sounds.

[0048] In some embodiments, when actually manufacturing the test device 10, part of the structure of the transducer assembly can be directly used, that is, the part of the transducer assembly without the transducer body is used, and the transducer shell and the conductive component arranged at the rear of the transducer shell are directly used to form the shell 3 and the conductive part 4 of the test device 10. Then, the detection assembly is electrically connected to the conductive part 4, and the mounting base 5 of the detection assembly is installed to one end of the shell 3 to form the test device 10 of this embodiment.

[0049] In some other embodiments, the structure of the shell 3 is the same as that of the transducer shell, but the conductive part 4 is different from the conductive parts on the transducer assembly. Specifically, the inner diameter of the first conductive part 41 is larger than the inner diameter of the outer conductive part, and the outer diameter of the first conductive part 41 is smaller than the outer diameter of the outer conductive part, so that the ring width of the first conductive part 41 is smaller than the ring width of the outer conductive part. At the same time, the outer diameter of the second conductive part 42 is smaller than the outer diameter of the inner conductive part, so that the size of the second conductive part 42 is also smaller than the size of the inner conductive part. In this way, when the conductive spring 2 is confirmed to be connected to the conductive part 4 by the test device 10, it can ensure a stable electrical connection with the transducer assembly when it is combined with the transducer assembly, which improves the test standard.

[0050] In summary, when the testing device 10 provided in this embodiment is used to test the installation position of the conductive spring 2 in the ultrasonic surgical knife, it can truly simulate the power-connected state of the transducer assembly when it is installed in the housing 1, and the test results are more accurate, which significantly improves the test reliability.
