Description

Technical Field

[0001] The utility model relates to the field of ultrasonic knife rods, in particular to an ultrasonic knife rod structure. Background Art

[0002] The ultrasonic scalpel is a medical device based on ultrasonic technology. Its principle is to convert high-frequency sound waves into energy for surgical cutting and coagulation of tissue. Compared with traditional surgical knives, the ultrasonic scalpel has many advantages. It can achieve more precise surgical operations and reduce damage to surrounding tissues. The cutting effect of the ultrasonic scalpel is smoother and reduces bleeding.

The internal structure of the ultrasonic cutter rod is the existing technology. To avoid redundancy, this article does not describe the internal structure of the cutter rod of the existing technology. The vibration principle and internal necessary structure of the ultrasonic cutter rod are both the existing technology. A rear tube 8 is inserted into the interior of the connecting rod 1, and a front tube 5 is inserted into the interior of the variable amplitude rod 2. One end of the front tube 5 is connected to one end of the rear tube 8, and the end of the front tube 5 away from the rear tube 8 is located on the side of the cutter head 3. The side wall of the connecting rod 1 is clamped with an outer tube 15, and the side wall of the outer tube 15 is fixed with a pipe mouth 16. The end of the rear tube 8 away from the front tube 5 is inserted in the pipe mouth 16. A smoking port 12 is opened on the side wall of the rear tube 8, and the smoking port 12 is located in the outer tube 15. The connection between the outer tube 15, the rear tube 8 and the front tube 5 is sealed.

[0028] This ultrasonic knife rod has a smoke absorption function. Before using the ultrasonic knife, the outer tube 15 is connected to an external device. The external device absorbs the air inside the outer tube 15 and absorbs the smoke through the outer tube 15, the smoke port 12, the rear tube 8, the front tube 5 and the smoke inlet 6. The smoke generated by the ultrasonic knife is absorbed to prevent the smoke from being inhaled and to prevent the smoke from affecting the doctor's vision clarity.

[0029] like Figure 2 、 Figure 4 、 Figure 7 As shown, the end of the amplitude transformer 2 is fixedly connected to a smoke inlet 6 at a position on one side of the cutter head 3, one end of the front tube 5 is located in the smoke inlet 6, and a fastener 7 is clamped on the outside of the smoke inlet 6 to prevent the front tube 5 from falling off.

[0030] The front tube 5 is inserted into the horn 2 from the smoke inlet 6 , and then the fastener 7 is clamped and installed. The fastener 7 prevents the front tube 5 from falling off from the smoke inlet 6 .

[0031] like Figure 2 、 Figure 4 、 Figure 6 As shown, a groove 10 is provided at one end of the connecting rod 1 close to the amplitude rod 2, a fixing part 9 is fixedly connected to one end of the rear tube 8, the fixing part 9 fits into the groove 10, a sealing part 11 is clamped on the inner wall of the fixing part 9, one end of the front tube 5 is inserted into the fixing part 9, and one end of the front tube 5 is squeezed into the sealing part 11.

[0032] When installing the rear tube 8, the horn 2 is not installed with the connecting rod 1. The rear tube 8 is inserted into the connecting rod 1 from the groove 10 until the fixing piece 9 fits in the groove 10. At this time, one end of the rear tube 8 is located in the outer tube 15. After the rear tube 8 is installed in the connecting rod 1, the horn 2 is installed, and then the front tube 5 is installed. One end of the front tube 5 is squeezed against the sealing piece 11 to seal the front tube 5 and the rear tube 8.

[0033] like Figure 1-Figure 5 As shown, the side wall of the connecting rod 1 is provided with a mounting opening 13, the outer tube 15 is inserted into the mounting opening 13, and the side of the mounting opening 13 away from the amplitude rod 2 is provided with a side opening 14 for inserting the pipe opening 16, and the side wall of the mounting opening 13 is provided with an inner groove 22 for rotating the pipe opening 16, and the inner groove 22 is connected to the slot.

The inner groove 22 is annular in shape, and the length of the annular outer wall is greater than half the length of the inner wall of the groove 10. The height of the groove 10 is the same as the height of the pipe opening 16. After the pipe opening 16 enters the inner groove 22, it can only be rotated in one direction. When it is rotated until it cannot rotate, the position of the pipe opening 16 is correct.

[0035] like Figure 2 、 Figure 4 、 Figure 5As shown, a socket 18 is provided on the inner wall of the mounting port 13 , which passes through the inner wall of the outer tube 15 . The socket 18 is rectangular in shape. An inner tube 19 is inserted into the outer tube 15 , and an insert 20 is fixedly connected to one end of the inner tube 19 for plugging with the socket 18 .

[0036] The outer tube 15 is inserted into the mounting opening 13 and rotated to a certain extent. The outer tube 15 is not prevented from rotating. The inner tube 19 is inserted into the outer tube 15. When the insert block 20 of the inner tube 19 is inserted into the socket 18, the outer tube 15 is fixed in position.
