Description

Technical Field

[0001] This utility model relates to the field of energy surgery technology for medical devices, specifically a device for detecting the adhesion of rubber coating on an amplitude rod. Background Technology

[0002] An ultrasonic surgical cutting instrument, hereinafter referred to as an ultrasonic scalpel, is disclosed. The main function of the ultrasonic scalpel is to achieve minimal thermal damage and vascular closure while cutting soft tissue. Existing methods for assessing the adhesion between the metal-coated amplitude transformer and the coated surface typically involve testing the peel force, shear force, and tensile force between the coated sample and the coating using a peel tester. However, the data obtained from the tested sample differs significantly from the actual product, resulting in poor data stability. Firstly, the appearance of the sample differs from the test object, rendering the measured adhesion value of the sample meaningless; different shapes of the coated area will cause deviations in the measurement results. Secondly, measuring the adhesion between the coating and the test object using a peel tester is cumbersome, requiring additional molds to control the coating thickness and shape, which can lead to uneven control and large errors in the measured adhesion. Furthermore, it is impossible to determine whether the coating will detach from the metal transformer even when the adhesion is satisfactory. In summary, the existing data on the adhesion between the amplitude transformer and the rubber coating is inaccurate and cannot be used as a reference value for judging the adhesion between the test object and the rubber. Furthermore, it cannot determine whether there is any detachment between the rubber coating and the metal, resulting in poor control over the adhesion quality of the rubber coating.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] In the accompanying drawings of the specific embodiments of this utility model, in order to better and more clearly describe the working principle of each component in the system and show the connection relationship of each part in the device, only the relative positional relationship between each component is clearly distinguished. It does not constitute a limitation on the signal transmission direction, connection sequence, or size, dimension, and shape of each part within the component or structure.

[0021] like Figure 1-3 As shown, the variable amplitude rod coating adhesion testing device of this utility model includes: a base 1, a linear guide rail 2, a push-pull force gauge 3, an X-axis rotating screw 4, a Y-axis rotating screw 5, a dial 6, an X-axis moving adjustment platform for the test object on the clamp side 7, and an X-axis moving adjustment platform for the test object on the rear side 8.

[0022] A linear guide rail 2 is installed on one end of the base 1. A rear X-axis movement adjustment platform 8 for the test object is installed at the rear end of the linear guide rail 2. A clamp-side X-axis movement adjustment platform 7 for the test object is installed at the front end of the base 1.

[0023] Adjust the rear test object X-axis movement adjustment platform 8 to move on the linear guide rail 2, so that it approaches the test object support block 9 at the front end of the linear guide rail where the test object is installed.

[0024] The X-axis movement adjustment platform 7 for the test object on the chuck side includes a chuck and a Y-axis rotating screw 5. The chuck has a dial 6, and the Y-axis rotating screw 5 is installed in front of the X-axis movement adjustment platform 7 for the test object on the chuck side.

[0025] The rear test object X-axis movement adjustment platform 8 includes a push-pull force gauge 3 and an X-axis rotating screw 4. The push-pull force gauge 3 is installed above the rear test object X-axis movement adjustment platform 8, and the X-axis rotating screw 4 is installed on the side of the rear test object X-axis movement adjustment platform 8.

[0026] As a preferred technical solution, the linear guide rail allows the test object (i.e., the rubber-coated amplitude rod) to move in the x-direction via the linear guide rail, and the tail end of the amplitude rod is locked to the push-pull force gauge via a threaded connection.

[0027] As a preferred technical solution, the linear guide rail moves the test object to the rubber coating position, and the rubber coating is fixed at the amplitude rod by the clamp. The distance from the rubber coating position of the amplitude rod is controlled by adjusting the scale of the clamp, and a reasonable moving distance is selected according to the diameter of the rubber coating.

[0028] As a preferred technical solution, after the clamp is fixed on one side of the rubber coating, the X-axis force gauge is moved by rotating the X-axis screw 4 left and right to make the rubber coating pass through the clamp under compression. After the rubber coating has completely passed through, the adhesion value of the rubber coating will be displayed on the force gauge. After the test, observe whether the rubber coating is damaged or falls off.

[0029] like Figure 4 The diagram shows the structure, shape, and position of the amplitude transformer bar of this invention. After the amplitude transformer bar is formed, it will be coated with rubber 10 according to the position and shape shown in the diagram. The rubber coating 10 of the amplitude transformer bar is used to absorb vibrations in high-frequency vibrations, making its operation more stable.

[0030] In a preferred embodiment, a comparative experiment was conducted on this solution. Adhesion force was measured using existing sample methods, and the peel force data was compared with that obtained using the solution of this invention. The experimental results are compared below:
