Description

Technical Field

[0001] The invention relates to the field of ultrasonic scalpel assembly, and in particular to an ultrasonic scalpel head assembly and an assembly device thereof. Background Art

[0002] The ultrasonic scalpel is a device that uses the principle of ultrasound to cut internal human tissues. It uses the extremely strong penetrating power of ultrasound to rupture the cell membrane of tumor tissue. At the same time, high-energy ultrasound releases huge energy that is quickly converted into heat energy, generating instantaneous high temperature at the focus, causing coagulative necrosis of tumor tissue. The ultrasonic scalpel is composed of a blade head assembly, a control handle and other components. The blade head assembly includes a blade rod and shears at one end of the blade rod assembly. A rotating wheel will be installed at one end of the blade rod, and the blade head assembly is connected to the control handle through the rotating wheel.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] An ultrasonic knife head assembly, such as Figure 1-Figure 3 As shown, it includes a tool rod 1, one end of which is plugged and installed with a fixed head 7, one end of which is rotatably connected to a pliers head 8, the pliers head 8 cooperates with the fixed head 7, an inner tooth 13 is fixedly connected to the inside of the pliers head 8, and outer teeth 12 are fixedly connected to both sides of the pliers head 8, the inner teeth 13 cooperate with the fixed head 7, a gasket 9 is clamped and installed inside the pliers head 8, the gasket 9 is located on one side of the inner tooth 13, and a semicircular arc-shaped protrusion 10 is provided on the gasket 9, and the protrusion 10 is squeezed and matched with the fixed head 7.

[0033] One end of the knife rod 1 is installed with a control handle, and the control handle controls the rotation of the forceps head 8 so that the forceps head 8 and the fixed head 7 shear the tissue. The inner teeth 13 and the outer teeth 12 increase the shearing ability of the knife head on the tissue. The protrusion 10 on the gasket 9 first contacts and squeezes the fixed head 7 to facilitate clamping of the tissue.

[0034] like Figure 1-Figure 3As shown, a rotating wheel 3 is sleeved on one end of the knife rod 1 away from the fixed head 7, a connecting tube 4 is fixedly connected to one end of the rotating wheel 3, the connecting tube 4 is sleeved on the knife rod 1, a hole 5 is penetrated between the knife rod 1 and the connecting tube 4, a pin 6 is inserted into the hole 5, and the pin 6 penetrates the connecting tube 4 and the knife rod 1.

[0035] The hole 5 on the connecting tube 4 is aligned with the hole 5 of the knife rod 1, and the hole 5 is plugged with a pin 6 to fix the knife rod 1 and the rotating wheel 3.

[0036] An assembly device for an ultrasonic knife head assembly, such as Figure 1-Figure 10 As shown, the assembly equipment includes a machine base 14, an assembly base 15 is fixedly connected to the upper end of the machine unit, a mounting groove 2 for plugging in a rotating head is provided on the assembly base 15, a tool rod 1 passes through the machine base 14 and the assembly base 15, a driving component for driving the tool rod 1 to rotate is rotatably connected between the machine base 14 and the assembly base 15, two groups of alignment components are symmetrically fixedly connected to the upper end of the assembly base 15, and the two groups of alignment components are respectively plugged in and matched with the two ends of the hole 5.

[0037] The rotating wheel 3 is first installed in the installation groove 2, and the installation groove 2 is installed in the rotating wheel 3, and the installation groove 2 can limit the installation direction of the rotating seat, so that when the rotating wheel 3 is installed on the assembly seat 15, the hole 5 is fixed in direction, and the alignment component is aligned with the hole 5 at this time, and the alignment component is controlled to be plugged into the hole 5, and the tool rod 1 is plugged into the rotating wheel 3. The lower end of the guide rod passes through the assembly seat 15 and the machine base 14, and the side wall of the tool rod 1 squeezes the alignment component in the hole 5, and the driving component drives the tool rod 1 to rotate until the side wall of the tool rod 1 no longer squeezes the alignment component in the hole 5. At this time, the hole 5 on the side wall of the tool rod 1 is aligned with the hole 5 of the rotating wheel 3, and the alignment component is separated from the hole 5, and the pin 6 can be installed. The rotating wheel 3 is assembled on the tool rod 1 using this equipment, and there is no need for eyesight, which reduces labor intensity and improves assembly efficiency.

[0038] like Figure 1 As shown, the alignment component includes a bracket 20, which is fixed to the upper end of the assembly seat 15, a fixed grid 21 is fixed to one side of the bracket 20, a moving grid 18 is slidably connected to the fixed grid 21, the lower end of the moving grid 18 is slidably connected to the upper end of the assembly seat 15 via a sliding frame 17, a round head 19 is fixed to the side of the moving grid 18 away from the bracket 20, the round head 19 is plugged into the hole 5, a connecting column 22 is fixed to one side of the bracket 20, one end of the moving grid 18 away from the round head 19 is slidably connected to the connecting column 22, and a spring 23 is fixed between the moving grid 18 and the bracket 20, and the spring 23 is sleeved on the connecting column 22.

[0039] The alignment components are symmetrically fixed on both sides of the rotating wheel 3. The round heads 19 on the two sets of alignment components are respectively inserted into the two ends of the hole 5. When the knife bar 1 is not inserted into the rotating wheel 3, the length of the round head 19 inserted into the hole 5 is slightly longer, and the movable fence 18 will generate a data on the fixed fence 21. The knife bar 1 is inserted into the rotating wheel 3, and the side wall of the knife bar 1 squeezes the round head 19. The round head 19 drives the sliding frame 17 to slide, and the length of the round head 19 entering the hole 5 becomes shorter. The movable fence 18 is displaced on the fixed fence 21. At this time, the data is compared with the knife bar 1 inserted into the rotating wheel 3. The spring 23 is compressed, and when the tool rod 1 is rotated to align with the hole 5, the spring 23 will squeeze the round head 19, and the length of the round head 19 entering the hole 5 becomes longer, and the data between the moving grid 18 and the fixed grid 21 is restored. By observing the data generated by the moving grid 18 on the fixed grid 21, the distance of the round head 19 entering the hole 5 can be judged. After the external device analyzes the data of the moving grid 18 and the fixed grid 21, the driving component and the pushing component are intelligently controlled, and the assembly between the tool rod 1 and the rotating wheel 3 is simple, fast and efficient.

[0040] like Figure 5-Figure 7 As shown, the assembly seat 15 is fixedly connected with a pushing component for squeezing the sliding frame 17, and the pushing component includes a fixed plate 25, which is fixedly connected to the assembly seat 15, and the upper end of the fixed plate 25 is rotatably connected with a cam 24 for squeezing the sliding frame 17, and the lower end of the cam 24 is fixedly connected with a toothed plate 26, and the toothed plate 26 is rotatably connected to the lower end of the fixed plate 25, and the lower end of the fixed plate 25 is fixedly connected with a servo motor 28, and the output end of the servo motor 28 is fixedly connected with an internal gear 27, and the internal gear 27 is meshed with the toothed plate 26 for transmission.

[0041] The internal gear 27 is controlled to rotate by a servo motor 28 (model TF-N20F), and the internal gear 27 meshes with the transmission toothed disc 26. The toothed disc 26 drives the cam 24 to rotate. The cam 24 squeezes the two sets of sliding frames 17, so that the sliding frames 17 can control the round heads 19 to disengage from the holes 5. After disengagement, it is convenient to install the pins 6. When the cam 24 rotates to no longer squeeze the sliding frames 17, it controls the alignment assembly to plug into the holes 5.

[0042] like Figure 4-Figure 10 As shown, the driving assembly includes a turntable 32, which is rotatably connected between the machine base 14 and the assembly base 15. The tool rod 1 passes through the middle of the turntable 32. An elastic assembly for squeezing the side wall of the tool rod 1 is slidably connected inside the turntable 32. A transmission assembly is slidably connected to the machine base 14. The transmission assembly is meshed with the turntable 32 for transmission, and the transmission assembly is extruded and matched with the elastic assembly.

[0043] The knife bar 1 passes through the middle of the turntable 32. Due to the presence of the assembly seat 15 and the rotating wheel 3, the knife bar 1 cannot be tilted. The transmission component is close to the turntable 32, and the meshing transmission transmits the turntable 32 to rotate. At the same time, the transmission component squeezes the elastic component. One end of the elastic component squeezes the knife bar 1. The friction between the elastic component and the side wall of the knife bar 1 increases, so that the turntable 32 drives the knife bar 1 to rotate a certain angle through the elastic component. Multiple groups of elastic components are arranged in a circular array, so that the transmission component squeezes the multiple groups of elastic components in turn, so that the knife bar 1 rotates intermittently.

[0044] like Figure 6-Figure 10 As shown, the elastic component includes a driving plate 34, which is slidably connected to the inside of the turntable 32, and a pressure plate 36 is fixedly connected to one end of the driving plate 34, and the pressure plate 36 is squeezed and matched with the side wall of the knife rod 1, and the other end of the driving plate 34 passes through the side wall of the turntable 32, and a slide plate 38 is fixedly connected to the side wall of the driving plate 34, and a spring 37 for resetting the driving plate 34 is fixedly connected between the slide plate 38 and the inside of the turntable 32.

[0045] When one end of the driving plate 34 located outside the turntable 32 is squeezed, the sliding plate 38 slides, the spring 2 37 is compressed, and the pressure plate 36 squeezes the side wall of the knife rod 1. The friction between the pressure plate 36 and the side wall of the knife rod 1 is large. The end of the driving rod located outside the turntable 32 is rounded or trapezoidal, which is convenient for rotational squeezing and prevents the turntable 32 from getting stuck. The turntable 32 drives the knife rod 1 to rotate a certain angle through the driving plate 34 and the pressure plate 36. When the turntable 32 rotates until the squeezed driving plate 34 is out of squeezing, the spring 2 37 will drive the driving plate 34 to reset. This group of pressure plates 36 are no longer squeezed with the side wall of the knife rod 1, and the adjacent driving plates 34 begin to be squeezed, thereby driving the knife rod 1 to rotate.

[0046] like Figure 6-Figure 10 As shown, the transmission assembly includes an external gear 31, which is slidably connected to the base 14, a toothed ring 33 is fixedly connected to the side wall of the turntable 32, the toothed ring 33 is meshed with the external gear 31 for transmission, a fixed ring 35 is fixedly connected to the side wall of the external gear 31, the fixed ring 35 is squeezed and fitted with one end of the driving plate 34, a driving member 29 is fixedly connected to the lower end of the base 14, a driving motor 30 is fixedly connected to the output end of the driving member 29, the driving motor 30 is slidably connected to the lower end of the base 14, and the output end of the driving motor 30 is fixedly connected to the middle part of the external gear 31.

[0047] After the knife bar 1 is inserted into the equipment, the driving member 29 (a device that can generate linear motion such as a cylinder) drives the driving motor 30 to slide, so that the outer gear 31 approaches the turntable 32, and the driving motor 30 (model 110ST-M05030) drives the outer gear 31 to rotate, so that the outer gear 31 engages with the tooth ring 33 on the side wall of the turntable 32 for transmission, and the turntable 32 rotates. At the same time, the fixed ring 35 on the outer gear 31 will squeeze the driving plate 34, so that the driving plate 34 drives the knife bar 1 to rotate intermittently.

[0048] The working principle of an ultrasonic knife head assembly and an assembly device thereof provided by the present invention is as follows:

[0049] The rotating wheel 3 is first fitted and installed on the mounting groove 2, at which time the alignment component is aligned with the hole 5, the round head 19 of the alignment component is controlled to be plugged into the hole 5, the tool rod 1 is plugged into the rotating wheel 3, the lower end of the guide rod passes through the assembly seat 15 and the machine seat 14, the side wall of the tool rod 1 squeezes the alignment component in the hole 5, the distance the alignment component enters the hole 5 changes, the driving component drives the tool rod 1 to rotate until the side wall of the tool rod 1 no longer squeezes the alignment component in the hole 5, at which time the hole 5 on the side wall of the tool rod 1 is aligned with the hole 5 of the rotating wheel 3, the distance the alignment component enters the hole 5 is restored, the pushing component controls the alignment component to be disengaged from the hole 5, and the pin 6 can be installed. The rotating wheel 3 is assembled on the tool rod 1 using this equipment, no vision is required, labor intensity is reduced, and assembly efficiency is improved.

[0050] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
