Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to an ultrasonic scalpel and an ultrasonic scalpel system. Background Art

[0002] An ultrasonic scalpel is a high-frequency electrosurgical device that can perform operations such as cutting, separating, and sealing biological tissues. It has the advantages of less bleeding, less damage to surrounding tissues, and faster postoperative recovery, and is widely used in operating rooms. The working principle of an ultrasonic scalpel is to output high-frequency vibrations along the axis of the waveguide rod to the waveguide rod through the transducer, and the waveguide rod performs operations such as cutting, separating, and sealing tissues through high-frequency vibrations. In existing ultrasonic scalpels, the connection between the transducer and the waveguide rod is a threaded connection, and the tightening of the thread is required to be achieved under a set torque to ensure the connection is highly efficient in transmitting ultrasonic vibrations. However, when the ultrasonic guide rod is long, due to the phenomenon of the far end deviation and swinging of the waveguide during vibration, the waveguide rod and the transducer generator will collide at the connection, thereby causing a howling problem. The longer the waveguide, the more obvious the howling problem. Utility Model Content

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0026] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0027] At present, the waveguide rod of the ultrasonic scalpel in the prior art is mostly connected to the transducer by a threaded connection, and the end face of the waveguide rod directly abuts against the transducer. The transducer converts electrical energy into mechanical vibrations and transmits the mechanical vibrations to the waveguide rod to drive the waveguide rod to vibrate along its own axis, thereby achieving tissue cutting or separation. However, during the vibration of the waveguide rod, the end face of the waveguide rod will collide with the end face of the transducer and produce whistling, which seriously affects the user experience of the ultrasonic scalpel. In order to solve the above problems, the present application provides an ultrasonic scalpel, and the specific solution is as follows:

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Please refer to Figures 1 to 3 As shown, in an embodiment of the present invention, an ultrasonic scalpel is provided, comprising a transducer 1, a waveguide rod 2, and a vibration isolator 4. The first connecting section 21 of the waveguide rod 2 is threadedly connected to the second connecting section 11 of the transducer 1. At least a portion of the vibration isolator 4 is disposed between a first end surface 211 of the first connecting section 21 and a second end surface 111 of the second connecting section 11, and abuts against the first end surface 211 and the second end surface 111, respectively.

[0030] Specifically, the transducer 1 refers to a device that converts electrical energy into other forms of energy. In specific applications, such as ultrasound, the ultrasonic transducer 1 is primarily used to convert electrical energy into mechanical vibration energy. The second connecting section 11 of the transducer 1 refers to the portion of the transducer 1 used for connection to other components. The second end surface 111 refers to a surface structure having a certain area on the second connecting section 11. The second end surface 111 can be a flat structure or a curved structure. The waveguide rod 2 refers to a component having a certain length. The waveguide rod 2 can be rod-shaped, cylindrical, or other shapes. The waveguide rod 2 is a key component in the ultrasonic scalpel that directly contacts the processing medium and conducts ultrasonic vibration energy. The waveguide rod 2 effectively transmits this energy to the scalpel's blade. The first connecting section 21 of the waveguide rod 2 refers to a region of the waveguide rod 2 located at the connecting end, where the connecting end refers to the end of the waveguide rod 2 away from the blade. The first end surface 211 refers to a surface structure having a certain area on the first connecting section 21. The first end surface 211 can be a flat structure or a curved structure. The vibration isolator 4 is a component that can support an object while also absorbing vibration energy. The vibration isolator 4 can be entirely made of a damping material, or partially made of a damping material with the remaining portion being a rigid material. This ensures that the vibration is absorbed while also providing a certain degree of rigidity to support the end faces of the waveguide rod 2 and the transducer 1. Furthermore, the vibration isolator 4 can be entirely disposed between the end faces of the threaded connection between the waveguide rod 2 and the transducer 1, or only partially disposed between the end faces of the threaded connection between the waveguide rod 2 and the transducer 1. The arrangement can be tailored to the specific situation.

[0031] The threaded connection between the first connecting section 21 of the waveguide rod 2 and the second connecting section 11 of the transducer 1 refers to a threaded structure provided between the waveguide rod 2 and the transducer 1 to connect the two. After the waveguide rod 2 and the transducer 1 are connected, at least a portion of the first end surface 211 can be arranged opposite at least a portion of the second end surface 111. The threaded connection can be achieved by providing a threaded column having a smaller diameter than the waveguide rod 2 on the first end surface 211 of the waveguide rod 2, and providing a threaded hole on the second end surface 111 of the transducer 1 to mate with the threaded column. Alternatively, the threaded connection can be achieved by providing a threaded column having a smaller diameter than the waveguide rod 2 on the transducer 1, and providing a threaded hole on the first end surface 211 of the waveguide rod 2 to mate with the threaded column. The threaded connection can also be that a connecting member 3 is provided between the first connecting section 21 of the waveguide rod 2 and the second connecting section 11 of the transducer 1, and both ends of the connecting member 3 can be provided with threads with opposite rotation directions, and threaded holes that cooperate with the threads on the connecting member 3 are provided on the first end face 211 of the waveguide rod 2 and the second end face 111 of the transducer 1. Of course, the threaded connection between the waveguide rod 2 and the transducer 1 can also adopt other forms, which will not be repeated here.

[0032] The ultrasonic scalpel provided in an embodiment of the present invention, by threading the first connecting section 21 of the waveguide rod 2 with the second connecting section 11 of the transducer 1, can transmit the vibration energy generated by the transducer 1 to the blade portion at the other end of the waveguide rod 2 during operation. A vibration isolator 4 is also provided between the first end face 211 of the first connecting section 21 and the second end face 111 of the second connecting section 11. Compared to ultrasonic scalpels in the prior art, by disposing at least a portion of the vibration isolator 4 between the first end face 211 of the first connecting section 21 and the second end face 111 of the second connecting section 11, and respectively abutting the first end face 211 and the second end face 111, the waveguide rod 2 and the transducer 1 can be spaced apart during operation of the ultrasonic scalpel, while also absorbing some of the vibration at the end face of the waveguide rod 2 facing the transducer 1, thereby preventing the waveguide rod 2 from colliding with the transducer 1 during operation and generating whistling. Furthermore, the waveguide rod 2 can also be prevented from heating and other phenomena.

[0033] In an alternative embodiment, see Figure 1 and Figure 2 A connector 3 is provided between the waveguide rod 2 and the transducer 1. Both ends of the connector 3 may be provided with threads. A first socket 5 is provided on the transducer 1, and a second socket 6 is provided on the waveguide rod 2. The inner walls of the first socket 5 and the second socket 6 are provided with threads that cooperate with the threads on the connector 3. Specifically, the connector 3 is a component of a certain length. The connector 3 may be provided with threads at both ends. The first socket 5 is provided on the transducer 1, and the second socket 6 is provided on the waveguide rod 2. The inner walls of the first socket 5 and the second socket 6 are provided with threads that cooperate with the threads on the connector 3. The connector 3 and the transducer 1 can be connected by the mutual cooperation of the threads on the inner wall of the first socket 5 and the threads on the connector 3. The connector 3 and the waveguide rod 2 can be connected by the mutual cooperation of the threads on the inner wall of the second socket 6 and the threads on the connector 3, ultimately achieving a threaded connection between the waveguide rod 2 and the transducer 1. In addition, through the setting of the connecting member 3, on the basis of realizing the connection between the waveguide rod 2 and the transducer 1, the threaded connection position between the waveguide rod 2 and the transducer 1 can also be supported by the connecting member 3, thereby making the connection between the waveguide rod 2 and the transducer 1 more secure. At the same time, it can also improve the energy transfer efficiency between the waveguide rod 2 and the transducer 1, making the use of the ultrasonic knife more convenient.

[0034] In one embodiment, see Figure 1 and Figure 2The vibration isolator 4 includes a vibration damping portion 41, which is arranged between the end faces of the threaded connection position of the waveguide rod 2 and the transducer 1, and respectively abuts against the end faces of the waveguide rod 2 and the transducer 1. Specifically, the vibration damping portion 41 refers to a component that can absorb vibration, and the vibration damping portion 41 can be in the shape of a plate, a sheet, or a block. The area between the end faces of the threaded connection position of the waveguide rod 2 and the transducer 1 refers to the area between the first end face 211 and the second end face 111. The vibration damping portion 41 is provided between the end faces of the threaded connection position of the waveguide rod 2 and the transducer 1. The waveguide rod 2 and the transducer 1 are separated by the vibration damping portion 41, and part of the vibration of the end face of the waveguide rod 2 facing the transducer 1 can also be absorbed to avoid collision between the waveguide rod 2 and the transducer 1 during operation and generate howling.

[0035] In an alternative embodiment, see Figure 3 The vibration-damping portion 41 is a plate-like structure with a certain thickness, and the shape of the vibration-damping portion 41 is adapted to the shape of the end face of the threaded connection position between the waveguide rod 2 and the transducer 1. For example, when the end face of the threaded connection position between the waveguide rod 2 and the transducer 1 is circular, the shape of the vibration-damping portion 41 may also be circular. By making the shape of the vibration-damping portion 41 adapted to the end face shape of the threaded connection position between the waveguide rod 2 and the transducer 1, the force at the threaded connection position can be made more uniform in the direction around the axis of the waveguide rod 2, thereby avoiding tilting or unstable installation of the waveguide rod 2 due to uneven force, and making the installation of the waveguide rod 2 more stable.

[0036] In addition, when the waveguide rod 2 and the transducer 1 are connected through the connecting member 3, an avoidance hole for avoiding the connecting member 3 can be provided on the vibration damping part 41. When the vibration damping part 41 is installed, the connecting member 3 can be passed through the avoidance hole on the vibration damping part 41, thereby making the installation of the vibration damping part 41 safer and more reliable.

[0037] In one embodiment, see Figure 3, the vibration damping part 41 is at least partially made of damping material, wherein the damping material includes a material whose hardness is less than the hardness of the transducer 1 and the waveguide rod 2 at the threaded connection position. Specifically, the damping material refers to a material that can convert the mechanical energy of the vibration of an object into heat energy, thereby reducing the vibration. It is mainly used for vibration control and achieves the purpose of shock absorption by dissipating vibration energy. The vibration damping part 41 is at least partially made of damping material, and another part of the vibration damping part 41 can be a rigid material. The damping material part and the rigid part on the vibration damping part 41 can form a multi-layer structure along the thickness direction, for example, a rigid part layer is provided between two damping material layers, or a damping material layer is provided between two rigid part layers. The vibration damping part 41 can also arrange the damping material part on the rigid part at intervals, for example, a plurality of damping material blocks are provided on the side of the rigid part. By making at least a portion of the vibration-damping part 41 from a damping material, the other portions of the vibration-damping part 41 can be made of a rigid material with a certain rigidity. This allows the vibration-damping part 41 to absorb vibrations and play a shock-absorbing role while also having a certain rigidity to support the waveguide rod 2, thereby making the installation of the waveguide rod 2 more stable.

[0038] In one embodiment, see Figure 3 , the damping material includes any one or more of rubber, plastic, aluminum and copper. Specifically, the damping material can be a single material, such as rubber, plastic, aluminum, copper and other materials with a certain elastic deformation ability and low hardness, which can absorb vibrations by elastically deforming or plastically deforming themselves. The damping material can also be composed of two or more materials. For example, copper is wrapped around the outside of the rubber, which can ensure vibration absorption while also increasing the service life of the rubber, so that the damping material can have the advantages of both materials at the same time. The use of the above-mentioned materials as the damping material can make the vibration damping part 41 have better vibration absorption ability and extend the service life of the device.

[0039] In one embodiment, see Figure 3 The thickness of the vibration damping portion 41 along the axial direction of the waveguide rod 2 is related to the material of the vibration damping portion 41. Specifically, when the vibration damping portion 41 is made of a material with strong vibration absorption but poor rigidity, such as rubber or plastic, the thickness of the vibration damping portion 41 along the axial direction of the waveguide rod 2 is relatively small to prevent excessive deformation of the vibration damping portion 41 along the axial direction of the waveguide rod 2, which could cause the waveguide rod 2 to tilt and affect the installation stability of the waveguide rod 2. When the vibration damping portion 41 is made of a material with poor vibration absorption but good rigidity, such as aluminum or copper, the thickness of the vibration damping portion 41 along the axial direction of the waveguide rod 2 is relatively large. This can prevent the vibration damping portion 41 from having insufficient thickness along the axial direction of the waveguide rod 2, resulting in poor vibration absorption, ineffective absorption of vibration at the end of the waveguide rod 2, and ineffective prevention of howling.

[0040] Furthermore, when the vibration damping portion 41 is made of a composite of multiple materials, the thickness of the vibration damping portion 41 along the axial direction of the waveguide rod 2 can be adjusted based on the properties of the materials. By flexibly selecting the thickness of the vibration damping portion 41 along the axial direction of the waveguide rod 2 based on the material of the vibration damping portion 41, the manufacturing cost of the vibration damping portion 41 can be reduced while maintaining the vibration absorption capacity of the vibration damping portion 41, thereby reducing the overall production cost of the ultrasonic scalpel.

[0041] In one embodiment, see Figure 3 , the vibration damping part 41 is set as a multi-layer structure along the axial direction of the waveguide rod 2, wherein the material composition of adjacent layers is different. Specifically, the multi-layer structure means that the vibration damping part 41 is composed of a plurality of stacked plates along the axial direction of the waveguide rod 2, and the multi-layer structures can be connected by pasting, fasteners or welding. By setting the vibration damping part 41 as a multi-layer structure along the axial direction of the waveguide rod 2, and at the same time, the material composition of adjacent layers in the multi-layer structure is different, wherein some layers are damping materials and some layers are rigid materials, the damping material and the rigid material can be formed into a multi-layer structure along the axial direction of the waveguide rod 2, so that the deformation of the vibration damping part 41 at various locations along the axial direction of the waveguide rod 2 can be kept uniform, and the vibration damping part 41 can also have a certain rigidity to support the waveguide rod 2 under the premise of ensuring the vibration absorption capacity of the vibration damping part 41, thereby making the installation of the waveguide rod 2 more stable, and making the use of the ultrasonic knife safer.

[0042] Based on the above characteristic multi-layer structure, please refer to Figure 3 , the thicknesses of adjacent layers in the vibration damping portion 41 vary. Specifically, because the adjacent layers in the vibration damping portion 41 are made of different materials, when some layers in the multilayer structure are made of materials with strong vibration absorption but poor rigidity, the thickness along the axial direction of the waveguide rod 2 is smaller. When some layers in the multilayer structure are made of materials with poor vibration absorption but good rigidity, the thickness along the axial direction of the waveguide rod 2 is larger. By selecting the thickness along the axial direction of the waveguide rod 2 based on the different materials in the multilayer structure, the overall manufacturing cost of the vibration damping portion 41 can be reduced.

[0043] In one embodiment, see Figure 3The vibration-damping portion 41 includes at least a support layer 411 and a damping layer 412 along the axial direction of the waveguide rod 2. The support layer 411 is made of copper, aluminum, or plastic, and the damping layer 412 is made of rubber or plastic. Specifically, the support layer 411 is a layered structure with relatively high rigidity, such as metal or ceramic. The damping layer 412 is a layered structure with relatively high vibration absorption capacity, such as rubber or plastic. The support layer 411 has greater rigidity than the damping layer 412, but the damping layer 412 has a greater vibration absorption capacity than the support layer 411. The support layer 411 and the damping layer 412 can also be arranged alternately. By having the vibration-damping portion 41 include at least the support layer 411 and the damping layer 412 along the axial direction of the waveguide rod 2, the vibration-damping portion 41 can have a certain rigidity to support the waveguide rod 2 while ensuring the vibration absorption capacity of the vibration-damping portion 411.

[0044] In a specific embodiment, see Figure 3 There is one supporting layer 411 and two damping layers 412, with the supporting layer 411 disposed between the two damping layers 412. The damping layer 412 is made of an elastic material such as rubber or polyurethane, while the supporting layer 411 is made of a metal such as aluminum or copper. The damping layer 412 is attached to the two surfaces of the supporting layer 411 by gluing, which makes the manufacture of the vibration damping portion 41 more convenient and reduces the manufacturing cost.

[0045] In another specific embodiment, there are two support layers 411 and one damping layer 412. The damping layer 412 is disposed between the two support layers 411. Similarly, the damping layer 412 is made of an elastic material such as rubber or polyurethane, while the support layer 411 is made of a metal material such as aluminum or copper. The support layer 411 is attached to the two surfaces of the damping layer 412 by gluing, thereby facilitating the manufacture of the vibration damping portion 41 and reducing manufacturing costs.

[0046] In one embodiment, see Figure 2 The vibration isolator 4 also includes a guide portion 42, which is connected to the vibration damping portion 41, and the guide portion 42 is sleeved on the outside of the transducer 1 and / or the waveguide rod 2 at the threaded connection position. Specifically, the guide portion 42 refers to a cylindrical component with a certain length, wherein the guide portion 42 is sleeved on the outside of the transducer 1 and / or the waveguide rod 2 at the threaded connection position, including the following situations: First, the guide portion 42 is sleeved on the outside of the transducer 1, and the vibration damping portion 41 can be set at the end of the guide portion 42 facing the waveguide rod 2. Second, the guide portion 42 is sleeved on the outside of the waveguide rod 2, and the vibration damping portion 41 can be set at the end of the guide portion 42 facing the transducer 1. Third, the guide portion 42 is sleeved on the outside of the waveguide rod 2 and the transducer 1 at the same time, and the vibration damping portion 41 can be set in the middle area of the guide portion 42.

[0047] By providing a guide portion 42 on the vibration isolation member 4, the transducer 1 and / or the waveguide rod 2 can be supported in the radial direction of the waveguide rod 2, which can limit the transducer 1 and / or the waveguide rod 2 in the radial direction of the waveguide rod 2, thereby avoiding the axis of the waveguide rod 2 and the axis of the transducer 1 from being out of alignment or generating an angle, making the installation position of the waveguide rod 2 more precise.

[0048] In an alternative embodiment, see Figure 2 The guide portion 42 can be integrally formed with the vibration damping portion 41, thereby making the connection between the guide portion 42 and the vibration damping portion 41 more secure, and improving the overall structural strength of the vibration isolator 4, while also reducing production costs.

[0049] On the basis that the guide portion 42 can be integrally formed with the vibration damping portion 41, when the vibration damping portion 41 is a multi-layer structure consisting of a support layer 411 and a damping layer 412, and the guide portion 42 is a single-layer structure, the metal material can be processed into a cylindrical structure with an opening only at one end by stamping, wherein the bottom surface of the cylindrical structure can be the vibration damping portion 41, and the side wall of the cylindrical structure can be the guide portion 42. Then, the damping layer 412 can be pasted on the inside and outside of the bottom surface of the cylindrical structure to form a multi-layer vibration damping portion 41. At the same time, it can also be ensured that the vibration damping portion 41 and the guide portion 42 are an integral structure, which can make the production of the entire vibration isolation member 4 more convenient and quick.

[0050] In a second aspect, an ultrasonic scalpel system is provided, comprising an ultrasonic mainframe and any of the above-mentioned ultrasonic scalpels, wherein the ultrasonic mainframe is electrically connected to the ultrasonic scalpel transducer 1. It is understood that the beneficial effects of the second aspect can be found in the relevant description of the first aspect, and will not be repeated here.

Based on the explanations herein, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention, as well as other specific embodiments of the present invention that can be devised by those skilled in the art without inventive effort, shall be included within the scope of protection of the present invention.
