Obviously, the embodiments to be described are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0051] It should be understood that the terms “comprising” and “including” as used in the specification and the appended claims indicate the presence of the recited features, integers, steps, operations, elements, and / or components but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0052] It should also be understood that the terms used in the specification of the embodiments of the present application are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present application. As used in the specification and the appended claims of the embodiments of the present application, the singular forms “a”, “an” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0053] Embodiment one:

[0054] Reference Figures 1-4The present invention provides an ultrasonic surgical scalpel handle 1, including a waveguide rod 14, an inner tube 11 and an outer tube 12. The waveguide rod 14 is used to transmit ultrasonic energy. The inner tube 11 is connected to the outer tube 12 and is sleeved on the outside of the waveguide rod 14. The inner tube 11 and the outer tube 12 are movable relative to each other.

[0055] The inner tube 11 and the outer tube 12 include multiple sections of pipe 13, which are connected end to end. Each pipe 13 has a connecting part at both ends. The two connecting parts are a first connecting part 131 and a second connecting part 132. The second connecting part 132 of the former pipe 13 is sleeved on the first connecting part 131 of the latter pipe 13. The two adjacent pipes 13 are connected by welding or adhesive bonding, or by any combination thereof.

[0056] It is understood that both the inner pipe 11 and the outer pipe 12 are composed of multiple pipe sections 13. Adjacent pipe sections 13 are joined together to form a complete pipe body. The pipe sections 13 are connected by a first connecting part 131 and a second connecting part 132. The inner diameter of the first connecting part 131 is smaller than the inner diameter of the second connecting part 132, and the outer diameter of the first connecting part 131 is smaller than the outer diameter of the second connecting part 132. The first connecting part 131 of the preceding pipe section 13 is inserted into the second connecting part 132 of the following pipe section 13, and exits from one end of the first connecting part 131 of the following pipe section 13. Since the outer diameter of the second connecting part 132 is larger than that of the first connecting part 132, the pipe body is formed by connecting the first connecting part 131 with the second connecting part 132. With an inner diameter of 131, one end of the next pipe 13 will be stuck on one end of the previous pipe 13. Then, welding and glue are applied at the connection point between the two adjacent pipes 13 to make the connection between the two adjacent pipes 13 stable. The entire pipe body is composed of multiple pipe segments 13. The pipe diameter of each pipe segment 13 can be directly set, and the pipes 13 can be combined into a preset pipe body. This avoids expanding the entire pipe to the preset inner diameter of the pipe body by the hole expansion method, improving the manufacturing accuracy of the pipe body size, and also preventing the pipe wall of the pipe 13 from cracking during manufacturing. At the same time, the sealing of the tool holder can be increased by connecting the sizes of the various pipes 13.

[0057] Specifically, the wall thickness of pipe 13 is 0.2 mm.

[0058] The edge of the outer periphery of the second connecting part 132 is provided with a clamping piece 1321, the inner surface of the first connecting part 131 is provided with a groove 1311, the first connecting part 131 of the previous pipe 13 is inserted into the inside of the subsequent pipe 13, the second connecting part 132 of the previous pipe 13 is in contact with the first connecting part 131 of the subsequent pipe 13, the clamping piece 1321 of the previous pipe 13 is clamped into the groove 1311 of the subsequent pipe 13, and the stability of the connection is improved; at the same time, when the two adjacent pipes 13 are connected, it can be directly judged whether the clamping piece 1321 is clamped into the groove 1311, so as to judge whether the pipes 13 are connected stably, and the connection between the pipes 13 is more convenient.

[0059] The first connecting part 131 and the second connecting part 132 are provided with an opening 133, and the first connecting part 131 is further provided with a ball 1312 corresponding to the opening 133 of the first connecting part 131 and the second connecting part 132. The diameter of the ball 1312 is greater than that of the opening 133, and the first connecting part 131 and the second connecting part 132 can be fixed by the ball 1312. It can be understood that the first connecting part 131 of the previous pipe 13 passes through the subsequent pipe 13, the second connecting part 132 is connected with the first connecting part 131 of the subsequent pipe 13, the positions of the openings 133 of the two are aligned, the ball 1312 is fixed by the opening 133, and the two adjacent pipes 13 are fixed by heating the ball 1312 during welding, so that the two adjacent pipes 13 are fixed, and the thickness change of the pipe wall during the connection between the pipes 13 is reduced.

[0060] The ultrasonic surgical knife rod 1 further comprises a clamp mouth 16 connected to one end of the inner tube 11 and the outer tube 12. The clamp mouth 16 comprises a connecting end 161 and a clamping end, the connecting end 161 is connected to the clamping end, the connecting end 161 is provided with two rotating shafts 162 and two fixing holes 163, the connecting end 161 is provided in a U shape, the two rotating shafts 162 are respectively arranged at both ends of the connecting end 161, and the fixing holes 163 are located away from the clamping end. It can be understood that the two fixing holes 163 are respectively arranged at both ends of the connecting end 161, one end of the inner tube 11 is provided with a hole, the rotating shaft 162 is inserted into the hole of the inner tube 11, one end of the outer tube 12 close to the clamp mouth 16 is provided with a hole and a fixing shaft, and the fixing shaft is inserted into the hole on the outer tube 12 and the fixing hole 163 on the connecting end 161. Specifically, one end of the inner tube 11 and the outer tube 12 away from the clamp mouth 16 is connected to a handle, the handle can move the inner tube 11 relative to the outer tube 12, the position of the fixing hole 163 is close to the center position of the cross section of the inner tube 11, the movement between the inner tube 11 and the outer tube 12 can move the connecting end 161, so that the clamping end of the clamp mouth 16 is away from or close to the waveguide rod 14, and the movement of the clamp mouth 16 can clamp the object.

[0061] The inner tube 11 is provided with a flow guide hole 111 near the forceps mouth 16, which is used for guiding the flow of liquid. When cutting, liquid such as blood and tissue fluid will flow back along the inner tube 11. The flow guide hole 111 can prevent the liquid from flowing into the end of the inner tube 11 away from the forceps mouth 16 along the waveguide rod 14.

[0062] The ultrasonic scalpel rod 1 further comprises a plug 15. The inner tube 11 and the outer tube 12 are provided with through holes, and the waveguide rod 14 is provided with a pin hole. The plug 15 passes through the through holes of the inner tube 11 and the outer tube 12 and the pin hole of the waveguide rod 14. The plug 15 passes through the through holes on the inner tube 11 and the outer tube 12 and the pin hole on the waveguide rod 14, thereby fixing the waveguide rod 14. At the same time, the through holes on the inner tube 11 or the outer tube 12 have different diameters, thereby facilitating the relative movement of the inner tube 11 and the outer tube 12. The waveguide rod 14 is fixed by the plug 15 and the pin hole, thereby preventing the waveguide rod 14 from moving with the inner tube 11 and the outer tube 12. In addition, the plug 15 can ensure that the inner tube and the outer tube are in the corresponding position with the waveguide rod 14, thereby preventing the position between the tube bodies from being dislocated. When installing, it is not necessary to detect again whether the tube bodies are in the correct position.

[0063] The end of the inner tube 11 away from the forceps mouth 16 is provided with an annular groove 112, and a sealing ring is placed in the annular groove 112 and in contact with the inner wall of the outer tube 12. Specifically, liquid often flows between the inner tube 11 and the outer tube 12. The end of the inner tube 11 near the forceps mouth 16 is provided with a flow guide hole 111, which is beneficial to the outflow of liquid. The end away from the forceps mouth 16 is also provided with an annular groove 112 and a sealing ring, thereby reducing the continuous entry of liquid into the gap between the inner tube 11 and the outer tube 12, allowing more liquid entering the inner tube 11 to flow out, and reducing the liquid near the sealing ring, thereby further avoiding the influence of the solidification of the liquid flowing into the inner tube 11 on the energy output efficiency of the ultrasonic scalpel 103 and reducing the influence on the movement of the inner tube 11.

[0064] The annular groove 112 on the inner tube 11 is made by a turning process. First, the surface of the tube material 13 is turned, and then the tube materials 13 are sleeved. The turning process can ensure the size standard of the annular groove 112. When the sealing ring is placed in the annular groove 112, it is close to the two tube walls of the inner tube 11 and the outer tube 12, thereby improving the sealing performance between the inner tube 11 and the outer tube 12.

[0065] Optionally, the waveguide rod 14 is provided with a spiral structure with the central axis of the waveguide rod 14 as the rotation axis 162. When the ultrasonic wave propagates along the axial direction of the transmission medium, a part of the longitudinal vibration ultrasonic wave is converted into torsional vibration ultrasonic wave rotating relative to the axial direction, thereby realizing the simultaneous generation of longitudinal vibration and torsional vibration ultrasonic waves when the ultrasonic wave propagates forward on the rod. At the same time, the spiral structure on the waveguide rod 14 can also be provided in various forms, such as a spiral slot, a twist drill, etc. This embodiment is not limited.

[0066] In particular, the waveguide rod 14 is made of titanium alloy, which can increase the transmission efficiency of ultrasonic energy of the waveguide rod 14.

[0069] Specifically, two adjacent pipe materials 13 are sleeved, the outer surface of the second connecting part 132 of the former pipe material 13 is close to the inner surface of the first connecting part 131 of the latter pipe material 13, the first limiting part 1313 is arranged on the outer surface of the second connecting part 132, the first limiting part 1313 extends away from the surface of the pipe material 13, the second limiting part 1322 is arranged on the inner surface of the first connecting part 131, and the second limiting part 1322 extends to the central axis position of the pipe material 13, so that the surfaces of the first limiting part 1313 and the second limiting part 1322 of the two pipe materials 13 abut against each other after the two adjacent pipe materials 13 are sleeved, the two pipe materials 13 are more stable when connected at both ends, at the same time, the first limiting part 1313 and the second limiting part 1322 can leave excess material when welding, so as to avoid the reduction of the wall thickness of the pipe wall and maintain the sealing property of the scalpel rod.
