[0055] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0056] It should be understood that the present invention can be implemented in different forms and should not be construed as being limited to the embodiments presented herein. On the contrary, providing these embodiments will make the disclosure thorough and complete, and will fully convey the scope of the present invention to those skilled in the art. In the accompanying drawings, the same reference numerals represent the same components throughout.

[0057] An ultrasonic knife head life test device, combined with reference to Figures 1 to 5 , including a test platform 1, a positioning component, a trigger action component 3 and a load simulation component 4, wherein the positioning component, the trigger action component 3 and the load simulation component 4 are all arranged on the test platform 1, the positioning component is used to position the ultrasonic knife equipped with the blade C to be tested on the test bench, the trigger action component 3 is used to simulate the repeated pulling action of the trigger B to control the opening and closing of the ultrasonic knife jaws D, and the load simulation component 4 is used to simulate the tissue clamped by the ultrasonic knife jaws D and generate a load.

[0058] Before the test, the ultrasonic scalpel equipped with the blade C to be tested is positioned on the test platform 1 using the positioning component, so that the load simulation component 4 corresponds to the position of the ultrasonic scalpel jaw D. During the test, the trigger action control component 3 repeatedly simulates the action of trigger B to produce a load at the ultrasonic scalpel jaw D, thereby being able to control the opening and closing of the ultrasonic scalpel jaw D. The ultrasonic scalpel blade life test device unifies the test conditions such as load and trigger action, which is conducive to making the test results more accurate.

[0059] In some embodiments, see Figures 2 to 5 , Fig. 9 , Fig.10 The positioning assembly includes a blade positioning assembly 210, which includes a blade positioning seat 21 and a blade pressing member 22 (not shown). The blade positioning seat 21 is arranged on the test platform 1, and the blade pressing member 22 is used to press the ultrasonic blade on the blade positioning seat 21. For example, see Figures 2 to 3 , four blade pressing members can be provided, each blade pressing member is used to press an ultrasonic knife onto a blade positioning seat 21, and then the four blade pressing members can press four ultrasonic knives onto the test platform 1 to achieve simultaneous testing of four ultrasonic knives, which is beneficial to improving the test efficiency. Of course, in the actual implementation process, each ultrasonic knife can also be pressed onto the same blade positioning seat by two or more blade pressing members, see Fig. 9 , Fig.10 Each ultrasonic knife can also be positioned on the test platform 1 through a knife body positioning seat 21 and a knife body pressing member 22.

[0060] In some embodiments, the clamping member may be a quick-action clamp (not shown).

[0061] In other embodiments, see Figures 9 to 12The positioning assembly includes not only the blade positioning assembly 210, but also the blade rod positioning assembly 220. Of course, in the actual implementation process, for example, only Fig. 9 , Fig.10 The blade body positioning assembly 210 is used, but the blade rod positioning assembly 220 is not provided. However, providing the blade rod positioning assembly 220 is conducive to more reliable positioning of the ultrasonic blade.

[0062] In some embodiments, see Fig. 9 , Fig.10 , Fig.12 The knife bar positioning assembly 220 includes a knife bar positioning seat 23 and a knife bar pressing member 24 for pressing the knife bar of the ultrasonic knife onto the knife bar positioning seat 23 .

[0063] In some embodiments, see Figures 9 to 11 The blade pressing member 22 includes a blade pressing head 221 and a first power cylinder 222. The blade pressing head 221 is driven by the first power cylinder 222 to press or move away from the blade of the ultrasonic knife.

[0064] In some embodiments, see Fig. 9 , Fig.10 , Fig.12 The knife bar pressing member 24 includes a knife bar pressing head 241 and a second power cylinder 242 . The second power cylinder 242 is driven by the knife body pressing head 221 to press or move away from the knife bar of the ultrasonic knife.

[0065] In some embodiments, the blade body clamping member 22 also includes a first pressure control valve for controlling the working pressure of the first power cylinder 222, and the blade rod clamping member 24 also includes a second pressure control valve for controlling the working pressure of the second power cylinder 242. By adjusting the corresponding control valves, the clamping force of each ultrasonic knife under test can be kept consistent during the test, which is beneficial to improving the accuracy of the test parameters.

[0066] In some embodiments, in conjunction with Figures 2 to 5 , Figures 9 to 12 The surface of the blade positioning seat 21 is provided with a recessed area 211 matching the contour of the handle A of the ultrasonic scalpel. The clamping piece is used to press the handle A of the ultrasonic scalpel into the recessed area 211. The provision of the recessed area 211 is conducive to more reliably pressing the ultrasonic scalpel onto the blade positioning seat 21.

[0067] In some embodiments, the blade pressing member 22 is disposed on the blade positioning seat 21 . In actual implementation, the blade pressing member 22 may also be disposed on the test platform 1 , as long as the ultrasonic blade can be pressed onto the blade positioning seat 21 .

[0068] In some embodiments, the first power cylinder 222 is a composite cylinder that integrates rotation and lifting actions. The first power cylinder 222 can be a pneumatic cylinder or an oil cylinder. For example, the first power cylinder 222 can be an ACKL32×90 angle oil cylinder. During the test, after the first power cylinder 222 drives the blade pressing head 221 away from the recessed area 211, it can also drive the blade pressing head 221 to rotate, so that before or after the test, the blade pressing head 221 can be moved out of the way, so that the blade of the ultrasonic knife can be directly taken out upward or inserted downward, which is more convenient to operate.

[0069] In some embodiments, a tool bar positioning groove 231 is also provided on the tool bar positioning seat 23 .

[0070] In some embodiments, the blade clamping member 22 also includes a cantilever member 223, the first power cylinder 222 is installed on the blade positioning seat 21 or the test platform 1, the cantilever member is installed on the first power cylinder 222 and moves with the first power cylinder 222, and the blade pressing head 221 is installed on the cantilever member 223.

[0071] In some embodiments, a connecting rod mechanism is arranged between the second power cylinder 242 and the knife bar press head 241, the second power cylinder 242 is a telescopic cylinder, and the connecting rod mechanism includes a first connecting rod 243 and a second connecting rod 244, the first connecting rod 243 is hinged on the telescopic rod of the second power cylinder 242; the second connecting rod 244 is hinged on the cylinder body of the second power cylinder 242; wherein, the knife bar press head 241 is arranged on the first connecting rod 243, and the second connecting rod 244 is hinged at the middle part of the first connecting rod 243, so that when the telescopic rod of the second power cylinder 242 is extended, the knife bar press head 241 is close to the knife bar positioning seat 23, and when the telescopic rod of the second power cylinder 242 is retracted, the knife bar press head 241 is away from the knife bar positioning seat 23. This way of arranging a connecting rod mechanism to transmit power can enable the tool rod pressure head 241 to have not only an upward displacement but also a lateral displacement when it is away from the tool rod positioning seat 23, so that in a non-testing state, there is no obstruction above the tool rod positioning seat 23, which is convenient for directly placing the ultrasonic knife tool rod into the tool rod positioning groove 231 during testing.

[0072] In actual implementation, the blade body clamping member may also adopt other structures besides the above-mentioned embodiments, as long as the ultrasonic blade can be pressed onto the blade body positioning seat, and the blade rod clamping member may also adopt other structures, as long as the ultrasonic blade rod can be pressed onto the blade rod positioning seat.

[0073] In some embodiments, see Figures 2 to 5 , Figures 9 to 12A sliding structure is provided between the blade positioning seat 21 and the test platform 1 for the blade positioning seat 21 to slide along the test platform 1, and the blade positioning seat 21 slides close to or away from the trigger action component 3. Before the test, after the ultrasonic knife is installed on the blade positioning seat 21, the blade positioning seat 21 is moved so that the ultrasonic knife moves with the blade positioning seat 21 until the position of the jaw D corresponds to the position of the load simulation component 4, and then the blade positioning seat is tested.

[0074] In some embodiments, see Figures 2 to 4 The sliding structure includes a slider (not shown) disposed on the positioning seat 21 and a slide groove 11 disposed on the test platform 1. The slider is located in the slide groove 11. A locking structure is disposed between the positioning seat 21 and the test platform. The positioning seat 21 is locked on the test platform 1 by the locking structure. The locking structure (not shown) is a bolt or a quick clamp. In other embodiments, see Figures 9 to 12 The sliding structure 5 can be a linear rail or a hard rail, and a control module is directly configured to control the travel position of each positioning seat on the corresponding linear rail and hard rail, so that the auxiliary effect generated by the load simulation component can be kept consistent in the position on the jaws D of each ultrasonic knife.

[0075] In some embodiments, see Figures 9 and 10 A sliding structure 5 is also provided between the tool bar positioning seat 23 and the test platform 1, so that the tool bar positioning seat 23 can slide along the test platform 1, and the tool bar positioning seat 23 can be adjusted to a suitable position to support the tool bar.

[0076] In some embodiments, see Fig. 9 , Fig.10 The positioning assembly includes two groups of knife bar positioning assemblies 220 and a group of blade positioning assemblies 210. Each knife bar positioning assembly 220 is arranged along the axial direction of the knife bar, wherein one group of knife bar positioning assemblies 220 is fixedly arranged on the test platform 1, and the group of knife bar positioning assemblies 220 is used to position the end of the knife bar, and the other group of knife bar positioning assemblies 220 is slidably arranged on the test platform 1. During the test, the end position of the knife bar can be first determined by the knife bar positioning assembly 220 fixedly arranged on the test platform 1, and then the position of the blade body and the remaining knife bars can be adjusted, which is conducive to unifying the clamping force of the end of the knife bar during the test, and can be applicable to ultrasonic knife positioning devices of different sizes. In the actual implementation process, the ultrasonic knife positioning assembly can include more than two groups of knife bar positioning assemblies 220, and multiple groups of knife bar positioning assemblies 220 can be fixedly arranged on the test platform 1, or multiple groups of positioning assemblies can be slidably arranged on the test platform 1.

[0077] In some embodiments, see Figure 3 , Figure 4 , Figure 5The trigger action assembly 3 includes a mounting base 31 arranged on the test platform 1, a telescopic member 32 installed on the mounting base 31, and a trigger member 33 moving with the telescopic member 32. The trigger member 33 is arranged on the telescopic member 32. The telescopic direction of the telescopic member 32 is consistent with the action direction of the trigger B of the ultrasonic scalpel, so that the trigger member 33 is pressed against the trigger B under the drive of the telescopic movement to complete the closing of the jaws D of the ultrasonic scalpel.

[0078] In some embodiments, the telescopic member 32 is a gas cylinder. In actual implementation, the telescopic member 32 may also be an oil cylinder, an electric push rod, etc., as long as it can achieve telescopic effect.

[0079] In some embodiments, the direction of trigger B is parallel to the surface of the test platform 1 , that is, the telescopic direction of the telescopic member 32 is also parallel to the surface of the test platform 1 . In actual implementation, the direction of trigger B is not limited thereto.

[0080] In some embodiments, see Figures 3 to 5 The load simulation component 4 includes a carrying belt 41 and a tensioning installation structure. The carrying belt 41 is used to clamp the jaws D of the ultrasonic knife head and withstand the fired ultrasonic waves. The tensioning installation structure is used to tension the carrying belt 41 and install the carrying belt 41 in the jaws D.

[0081] In some embodiments, see Figures 3 to 5 The tensioning installation structure includes a driving wheel 42, a driven wheel 43 and a driving member 44. The carrying belt 41 is tensioned between the driving wheel 42 and the driven wheel 43. The driving member 44 is used to drive the driving wheel 42 to rotate. In the actual implementation process, the driving member 44 can be a stepping motor. The stepping motor can be set so that when the trigger B triggers the jaw D to close, the carrying belt 41 is in a stationary state, and after the firing is completed, the driving wheel 42 is driven to rotate.

[0082] In some embodiments, see Figures 2 to 5 The test platform 1 is provided with a groove 12, the centers of the driven wheel 43 and the driving wheel 42 are both higher than the test platform 1, and the driven wheel 43 and the driving wheel 42 are partially installed in the groove 12. On the one hand, the provision of the groove 12 is conducive to lowering the center of gravity of the tensioning installation structure, which is conducive to the stability of the structure. On the other hand, the groove 12 can also collect lubricating oil on the tensioning installation structure, which is conducive to keeping the test platform clean.

[0083] In some embodiments, see Figure 6 The load simulation assembly 4 also includes a height adjustment structure for limiting the height of the carrying belt 41 from the test platform 1. Figure 7 The position adjustment structure may be a bending member, which includes a fixing portion 451 fixed on the test platform 1 and a height limiting portion 452 for limiting the height position of the carrier belt 41 .

[0084] In some embodiments, the test platform 1 is provided with multiple workstations, each of which corresponds to a set of trigger action components 3, so that the blades of multiple ultrasonic scalpels can be tested separately at the same time. For example, Figure 3 to Figure 4 In the present invention, four testing stations are set up, and the blade heads of four ultrasonic knives can be tested at the same time. Of course, in the actual implementation process, only one station can be set up.

[0085] In some embodiments, each test station shares the same set of positioning components and the same set of load simulation components 4. In actual implementation, each test station may correspond to a set of positioning components, and each test station may share a set of load simulation components, so that load unification can be achieved.

[0086] The present invention also provides an ultrasonic knife head testing system, see Figure 8 ,include:

[0087] Any of the above ultrasonic knife head life test devices;

[0088] A general control module, which is used to control the action of the trigger action component and the firing of the ultrasonic knife; and

[0089] A host computer, which is used to set test conditions through the general control module;

[0090] Wherein, the host computer is connected to the general control module, and the general control module is respectively connected to the host and trigger action component of the ultrasonic knife.

[0091] The ultrasonic scalpel head test system can not only control the trigger action but also control the firing of the ultrasonic scalpel, which is more conducive to unifying the test conditions and improving the reliability of the test results. In the actual implementation process, if there is an actuator (such as a motor) in the load simulation component, the action of the actuator in the load simulation component can also be controlled by the ultrasonic scalpel test system.

[0092] In some embodiments, see Figure 8, the power element (such as a cylinder) in the trigger action component 3 and the power element (such as a stepper motor) in the load simulation component 4 can all be controlled to start and stop and the start and stop interval time through the control system. For example, the control system can include a motor driver, a solenoid valve, a relay module, a general control module and a host computer, the host computer is connected to the general control module, the general control module, the motor driver, the motor are connected in sequence, the general control module, the relay module, the battery valve and the cylinder are connected in sequence, the host computer controls the general control module according to the interface setting parameters, and the output level of the general control module controls the relay module and the motor driver. The relay module drives the solenoid valve to control the cylinder to push the fixture to simulate the trigger of the blade C trigger B, and the relay can also simulate the foot switch signal through the simulated foot switch interface to control the host of the ultrasonic knife to output; the motor driver outputs a motor drive signal to control the stepper motor movement to drive the simulated load movement. In the actual implementation process, the general control module can use a USB5935 data acquisition card. This setting method can set the firing time, the number of tests, and the movement mode of the load simulation component 4 through the host computer, which is more conducive to unifying the test conditions.

[0093] In the description of the present invention, unless otherwise clearly stipulated and limited, a first feature being “on” or “under” a second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through another feature between them.

It should also be understood that the terms "comprising" and / or "including", when used in this specification, determine the presence of the features, integers, steps, operations, components and / or parts, but do not exclude the presence or addition of one or more other features, integers, steps, operations, components, parts and / or groups.

[0095] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
