[0002] An ultrasonic scalpel is a high-frequency electrosurgical device, mainly used for operations such as cutting of biological tissues and vascular closure.

Those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0032] During the assembly process of the ultrasonic scalpel, if there is a problem with the electrode seat, it will cause the ultrasonic scalpel to fail to fire. Therefore, it is necessary to ensure that the electrode seat can be used normally before installation.

[0033] To ensure the stability of the connection of the ultrasonic scalpel electrode seat, the electrode seat is often arranged inside the protective shell. If the direct connection method is used for measurement, it is necessary to extend into the inner side of the protective shell for connection, which is relatively difficult. As Figure 1 The structure shown is the structure of the ultrasonic scalpel electrode seat, which includes a first conductor 810, a second conductor 820, and a concave portion 830 at the center of the electrode seat. To clearly show the structure of the electrode seat, the protective shell part outside the electrode seat is not drawn. When conducting a conduction test on the electrode seat, it is necessary to insert the ultrasonic scalpel electrode conduction detection device of the present utility model into the protective shell and further insert it onto the electrode seat.

[0034] Refer to Figure 2As shown in the figure, an ultrasonic scalpel electrode conduction detection device according to an embodiment of the present invention includes a first sleeve 100, a first contact assembly 200, a second sleeve 300, and a second contact assembly 400. At least one first guide groove 110 is provided on the inner side wall of the first sleeve 100, and the first guide groove 110 is parallel to the axial direction of the first sleeve 100; the first contact assembly 200 is disposed in the first guide groove 110; the second sleeve 300 is coaxially disposed in the first sleeve 100, and at least one second guide groove 310 is provided on the inner side wall of the second sleeve 300, and the second guide groove 310 is parallel to the axial direction of the second sleeve 300. The end surface of the second sleeve 300 facing the first contact assembly 200 does not exceed the end surface of the first sleeve 100; the second contact assembly 400 is disposed in the second guide groove 310, and along the axial direction of the first sleeve 100, the second contact assembly 400 and the first contact assembly 200 are spaced apart. The ultrasonic scalpel electrode conduction detection device of the present invention can simply and quickly perform connection detection on the electrode seat part, avoiding the inability to fire the assembled ultrasonic scalpel.

[0035] When the ultrasonic scalpel is assembled, one of the semi-finished components is the electrode seat assembly. The electrode seat assembly is the core component for the ultrasonic scalpel to connect to the power supply. If there is a problem with the electrode seat, the ultrasonic scalpel will not be able to fire. Therefore, it is necessary to ensure that the electrode seat can be used normally before installation.

[0036] When performing electrode seat conduction detection, the first sleeve 100 is aligned with the first conductor 810 of the electrode seat and inserted. The first conductor 810 can enter the inside of the first sleeve 100. At the same time, the first contact assembly 200 inside the first sleeve 100 can be in contact conduction with the first conductor 810. The second sleeve 300 is disposed inside the first sleeve 100. Therefore, when designing the ultrasonic scalpel electrode conduction detection device, the axial relative position between the second sleeve 300 and the first sleeve 100 matches the first conductor 810 and the second conductor 820 of the electrode seat. Therefore, the second conductor 820 can enter the inside of the second sleeve 300, and at the same time, the second contact assembly 400 inside the second sleeve 300 can be in conduction with the second conductor 820. Of course, the first contact assembly 200 and the second contact assembly 400 on the ultrasonic scalpel electrode conduction detection device can be electrically connected to the test system in advance. Therefore, when the first contact assembly 200 contacts the first conductor 810 and the second contact assembly 400 contacts the second conductor 820, the conduction detection of the electrode seat can be performed.

[0037] It should be understood that, in order to ensure electrical safety, the first conductor 810 and the second conductor 820 are not arranged in the same plane, so there is an axial spacing distance between the first conductor 810 and the second conductor 820. Therefore, the end face of the second sleeve 300 facing the first contact assembly 200 does not extend beyond the end face of the first sleeve 100; the second contact assembly 400 is arranged in the second guide groove 310, and along the axis of the first sleeve 100, the second contact assembly 400 and the first contact assembly 200 are spaced apart.

[0038] Referring Figure 3 and Figure 4 As shown, it can be understood that the second sleeve 300 is movably connected to the first sleeve 100, and the second sleeve 300 can axially move to change the axial distance between the first contact assembly 200 and the second contact assembly 400.

[0039] For electrode holders of different models, the axial spacing distance between the first conductor 810 and the second conductor 820 is different. Of course, in order to adapt to the design differences between different models of electrode holders, an axially movable connection is adopted between the second sleeve 300 and the first sleeve 100, which can manually adjust the relative positions of the second sleeve 300 and the first sleeve 100 in the axial direction to change the relative positions of the first contact assembly 200 and the second contact assembly 400 in the axial direction. Finally, it is ensured that when the first contact assembly 200 is reliably connected to the first conductor 810, the second contact assembly 400 can also be reliably connected to the second conductor 820.

[0040] Referring Figure 3 As shown, it can be understood that an annular boss 120 is provided on the inner wall of the first sleeve 100 on the side away from the first contact assembly 200, the second sleeve 300 is inserted into the annular boss 120, and the second sleeve 300 is threadedly connected to the annular boss 120.

[0041] In order to enable the second sleeve 300 to be movably connected to the first sleeve 100, one way is to perform axial adjustment through a threaded connection. In the above-mentioned threaded connection structure, the first sleeve 100 is fixed, and the second sleeve 300 is rotated. The threaded fit between the second sleeve 300 and the annular boss 120 can drive the second sleeve 300 to axially move, thereby changing the axial distance between the first contact assembly 200 and the second contact assembly 400. In addition, the threaded connection between the second sleeve 300 and the annular boss 120 can also achieve the locking of the axial movement, that is, when no torque is applied to the second sleeve 300, the second sleeve 300 is only subjected to an axial force and it is difficult to change the position between the second sleeve 300 and the first sleeve 100.

[0042] Referring Figure 4As shown, it can be understood that on the inner wall of the side of the first sleeve 100 away from the first contact assembly 200, there are two annular baffles 130. The two annular baffles 130 are distributed at intervals. Between the two annular baffles 130, there is a hollow columnar friction block 140. The second sleeve 300 passes through the friction block 140 and the two annular baffles 130, and the outer side wall of the second sleeve 300 is in sliding friction contact with the friction block 140.

[0043] In order to enable the second sleeve 300 to be movably connected to the first sleeve 100, another way is to perform axial adjustment through frictional contact. In the above structure, the outer wall of the second sleeve 300 is in frictional contact with the inner side wall of the friction block 140. When it is necessary to move the second sleeve 300, an axial force needs to be applied to the second sleeve 300 to overcome the sliding friction force between the second sleeve 300 and the friction block 140. The sliding friction force between the second sleeve 300 and the friction block 140 can also lock the axial movement within a certain range, that is, when the axial force on the second sleeve 300 is less than the sliding friction force, the second sleeve 300 cannot move axially. The sliding friction force between the second sleeve 300 and the friction block 140 can be adjusted by changing the material of the friction block 140 or changing the surface roughness of the friction block 140.

[0044] Preferably, the friction block 140 is a rubber block.

[0045] The rubber block has elasticity. By utilizing the elastic deformation characteristic of the rubber block, an interference fit can be achieved between the second sleeve 300 and the rubber block, further increasing the frictional force between the second sleeve 300 and the rubber block. The locking ability of the rubber block to the second sleeve 300 is improved.

[0046] It can be understood that on the side of the second sleeve 300 away from the second contact assembly 400, a guide cylinder 500 is coaxially provided. An activity column 600 is installed in the guide cylinder 500. The guide cylinder 500 is provided with an adjustment assembly 700. The adjustment assembly 700 is in transmission connection with the activity column 600 to drive the activity column 600 to extend into the second sleeve 300.

[0047] The purpose of setting the activity column 600 is to further improve the stability of the connection between the ultrasonic knife electrode conduction detection device and the electrode seat. Specifically, when the ultrasonic knife electrode conduction detection device is inserted into the electrode seat, the adjustment assembly 700 is used to push the activity column 600 into the second sleeve 300, so that the activity column 600 can be embedded in the recess 830 at the center of the electrode seat, realizing the movement restriction of the electrode seat. After the conduction detection of the electrode seat is completed, the activity column 600 is retracted into the guide cylinder 500 again by using the adjustment assembly 700.

[0048] Refer to Figure 5As shown, it can be understood that an annular clamping plate 510 is provided at one end of the guiding cylinder 500 away from the second contact assembly 400. The movable column 600 is connected with an adjusting bolt 710. The adjusting bolt 710 is in threaded connection with the movable column 600. A clamping groove is provided in the circumferential direction of the adjusting bolt 710, and the annular clamping plate 510 is clamped in the clamping groove.

[0049] The adjusting bolt 710 constitutes an adjusting assembly 700. The clamping groove of the adjusting bolt 710 is restricted by the annular clamping plate 510, so that the adjusting bolt 710 can only rotate circumferentially and cannot move axially. Therefore, when the adjusting bolt 710 rotates, the movable column 600 connected thereto can move axially along the guiding cylinder 500.

[0050] It should be understood that for the assembly of the adjusting bolt 710 and the guiding cylinder 500, the guiding cylinder 500 can be made of plastic material and formed by injection molding. The guiding cylinder 500 is evenly divided into two halves along the central plane. The adjusting bolt 710 is placed in the two halves, and the positions of the clamping groove and the annular clamping plate 510 are aligned. Combining the two halves can restrict the adjusting bolt 710 in the guiding cylinder 500. Finally, the guiding cylinder 500 can be connected to the side of the second sleeve 300 away from the second contact assembly 400 by ultrasonic welding.

[0051] It can be understood that a chamfer is provided at one end of the movable column 600 facing the second contact assembly 400.

[0052] In order for the movable column 600 to be inserted into the recess 830 more smoothly, a chamfer can be provided at one end of the movable column 600 facing the second contact assembly 400. Because one end of the movable column 600 facing the second contact assembly 400 moves towards the second conductor 820 during movement, and the recess 830 is at the center of the second conductor 820.

[0053] It can be understood that the first guide groove 110 is provided with a conductive sheet 210. The conductive sheet 210 has a trapezoidal structure. One set of parallel sides of the conductive sheet 210 are a long side and a short side respectively. The long side is embedded in the first guide groove 110, and the short side is located inside the first sleeve 100. The conductive sheet 210 is deformable.

[0054] The conductive sheet 210 in the first guide groove 110 constitutes the first contact assembly 200.

[0055] The trapezoidal conductive sheet 210 has good deformation characteristics. The short side of the conductive sheet 210 can extend towards the inside of the first sleeve 100. When the first sleeve 100 is inserted towards the first conductor 810, the first conductor 810 contacts the short side of the conductive sheet 210 and squeezes the short side to cause deformation. The deformed conductive sheet 210 has a tendency to return to its original state. Therefore, the conductive sheet 210 will exert a force on the first conductor 810, which is equivalent to that the conductive sheet 210 can stably contact the first conductor 810 to complete circuit conduction.

[0056] It should be understood that the second contact component 400 may have the same structure as the first contact component 200, that is, the second contact component 400 may adopt another set of conductive sheets.

[0057] It can be understood that three first guide grooves 110 are provided on the inner side wall of the first sleeve 100, and the three first guide grooves 110 are evenly spaced along the circumferential direction of the first sleeve 100.

[0058] The first guide grooves 110 are evenly distributed, that is, the conductive sheets 210 can be evenly distributed. No matter what circumferential angle the first sleeve 100 is in, the first conductor 810 can be in contact with at least one conductive sheet 210.

[0059] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
