Description

Technical Field

[0001] This utility model relates to the field of mechanical tooling technology, and in particular to a handle pressing device for an ultrasonic transducer. Background Technology

[0002] Ultrasonic scalpels are used in surgery to cut living tissue, and in recent years, ultrasonic electroscalpels have also gradually begun to be used. Ultrasonic electroscalpels combine the advantages of both ultrasonic scalpels and electroscalpels; they can not only convert ultrasonic signals into mechanical vibrations for cutting, but also output high-frequency currents for vascular sealing, resulting in better surgical outcomes in clinical applications.

[0003] Both ultrasonic scalpels and ultrasonic electroscalpels require the use of an ultrasonic transducer (hereinafter referred to as the transducer in this manual) during operation. The transducer mainly consists of an internal mechanism and an external handle housing.

[0004] To facilitate the fixing of the internal mechanism of the transducer and its connection with wires and cables, the handle housing of the transducer is usually designed as a two-section structure. The first section houses the internal mechanism, and the second section houses the cables. Therefore, a handle pressing device suitable for this type of transducer is needed to complete the assembly of the two handle sections. Utility Model Content

[0005] To address the problems in related technologies, this utility model provides an ultrasonic transducer handle pressing device to achieve interference pressing between the two sections of the transducer handle.

[0006] Therefore, this utility model provides a handle pressing device for an ultrasonic transducer, the pressing device comprising:

[0007] A mold frame, wherein a top plate and a bottom plate are connected by a support member, and an internal hollow structure is formed between the top plate and the bottom plate;

[0008] The movable rod penetrates vertically through the top plate;

[0009] An upper positioning element is provided at one end of the moving rod near the base plate to define the top of the handle of the transducer to be pressed.

[0010] An operating handle is located at the end of the moving rod away from the top plate, and is used to convert the applied external force into the movement of the moving rod, thereby driving the upper positioning member to move in a direction perpendicular to the bottom plate;

[0011] The lower positioning component is set on the base plate and is coaxial with the center of the upper positioning component. The lower positioning component is a hollow cylinder, and the side of the cylinder has an opening that penetrates the cylinder for leading out the cable of the tail of the transducer to be pressed. The inner wall of the lower positioning component is adapted to the shape of the tail of the handle of the transducer to be pressed.

[0012] The transducer handle pressing device provided by this utility model achieves interference fit between the two sections of the transducer handle through a simple structure, while ensuring the overall consistency of the handle shell. This handle pressing device can also be adjusted and adapted by replacing the positioning parts according to the handle specifications, offering advantages such as labor-saving pressing, convenient adjustment, and wide applicability.

Detailed Implementation

[0023] In the following description, exemplary embodiments of the present invention will be presented in detail with reference to the accompanying drawings to enable those skilled in the art to readily implement them. Furthermore, for clarity, portions irrelevant to the description of exemplary embodiments have been omitted from the drawings.

[0024] In this specification, it should be understood that terms such as “comprising” or “having” are intended to indicate the presence of features, figures, steps, behaviors, components, parts or combinations thereof disclosed in this specification, and are not intended to exclude the possibility of the presence or addition of one or more other features, figures, steps, behaviors, components, parts or combinations thereof.

[0025] It should also be noted that, unless otherwise specified, the embodiments and features described in this specification can be combined with each other.

[0026] The technical solution of this utility model will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0027] Figure 1 This illustration shows a transducer structure for which the handle pressing device of this invention can be applied.

[0028] like Figure 1 As shown, the transducer 100 includes a front housing 110 and a rear housing 120. The transducer mechanism 130 is fixed inside the front housing 110. The transmission rod at the head of the mechanism extends out of the front housing. The rear housing 120 contains a wire connector. The cable 140 enters from the tail of the rear housing 120 and connects to the wire on the mechanism.

[0029] The transducer handle has already been wired before pressing. At this point, in addition to the front and rear housings, there are wires connecting the two sections of the handle. Therefore, when pressing the two housings of the handle, it is necessary to ensure that the inner core, internal wires, and external cables are not damaged. On the other hand, considering that the transducer will generate ultrasonic vibrations during use, the handle needs to maintain overall consistency. The interference fit process between the front and rear housings of the handle can effectively suppress resonance and reduce vibration noise, and the superimposed sealing rings can also achieve good sealing performance. To meet these requirements, a corresponding pressing fixture needs to be designed.

[0030] Figure 2 This illustration shows one embodiment of the transducer handle pressing device of this utility model. Figure 3 The diagram illustrates a front view of the handle pressing device of this embodiment.

[0031] like Figure 2 or Figure 3 As shown, the handle pressing device 200 includes:

[0032] The mold frame 210 is connected by a support member 211 to a top plate 212 and a bottom plate 213, forming an internal hollow structure between the top plate 212 and the bottom plate 213;

[0033] Movable rod 220, vertically penetrating the top plate 212;

[0034] The upper positioning component 230 is located at one end of the moving rod 220 near the bottom plate and is used to limit the top of the handle of the transducer to be pressed.

[0035] The operating handle 240 is located at the end of the moving rod 220 away from the top plate. It is used to convert the applied external force into the movement of the moving rod 220, thereby driving the upper positioning member 230 to move in a direction perpendicular to the bottom plate.

[0036] The lower positioning component 250 is mounted on the base plate 213 and is coaxial with the upper positioning component 230. The lower positioning component 250 is a hollow cylinder with an opening 251 on its side for leading out the cable from the tail of the transducer to be pressed. The inner wall of the lower positioning component conforms to the shape of the tail of the transducer handle to be pressed (see reference). Figure 6 ).

[0037] According to an embodiment of this utility model, the moving rod 220 of the handle pressing device 200 has a threaded shaft, and a fixing nut 260 is provided on the top plate 212. The moving rod 220 passes through the fixing nut 260 and penetrates the top plate 212. The function of the fixing nut 260 is to limit the linear movement of the moving rod 220 in the vertical direction during rotation. The fixing nut ensures the linear movement of the moving rod, thereby driving the linear movement of the upper positioning member and ensuring uniform force applied during the pressing process. In some embodiments, a sliding lead screw and a matching nut can be used to achieve the above structure.

[0038] The mold base 210 can be made of a rigid base material to enhance support, for example, stainless steel. The upper and lower positioning parts can be made of aluminum alloy. In addition, a soft, cushioning base layer, such as flocked cloth or thin sponge, can be provided on the inner wall of the positioning parts to protect the outer surface of the handle housing.

[0039] According to an embodiment of this utility model, a positioning mark can also be provided on the body of the moving rod 220 to indicate the moving distance of the moving rod, thereby locating the pressing position of the upper positioning member 230. The positioning mark can be a line segment drawn on the rod body. When the moving rod rotates and moves, if the line segment is flush with the upper edge of the nut fixing member, it indicates that the upper positioning member has reached a set pressing position, reminding the operator to stop applying force. When the transducer handles to be pressed have different length specifications, setting different positioning marks helps to improve operating procedures and obtain a suitable pressing effect. The positioning mark can also be a symbol drawn on the rod body, which cooperates with another symbol set on the fixing nut. For example, the positioning mark is an arrow. When the two arrows on the moving rod and the fixing nut coincide, it is considered that the predetermined pressing position has been reached, thereby obtaining a more accurate positioning effect.

[0040] Figure 4This illustration shows another angle view of the handle pressing device in this embodiment.

[0041] like Figure 4 As shown, the upper positioning member 230 is a hollow cylindrical structure. Its outer edge is used to abut against the handle housing of the transducer to be pressed to apply pressure, and the hollow interior of the cylinder is used to accommodate the inner core head of the transducer to be pressed. This structure of the upper positioning member facilitates the uniform application of pressure to the handle housing without damaging the inner core of the transducer.

[0042] According to an embodiment of this utility model, the lower positioning member 250 is a column that can be separated from the base plate 213. The base plate 213 has a coaxial limiting hole 214 coaxial with the upper positioning member 230 for placing the lower positioning member 250. During pressing, the upper and lower positioning members, together, limit the transducer handle, ensuring coaxial contact between the upper and lower sections and achieving interference fit under uniform force. Simultaneously, the hollow structure of the upper and lower positioning members ensures sufficient contact with the handle and prevents damage to the transducer core, thus guaranteeing the overall consistency of the handle.

[0043] Furthermore, considering that the workpieces to be pressed may have different specifications and models, the lower positioning parts that adapt to the tail of the handle may also have different specifications. Therefore, an additional non-coaxial limiting hole 215 can be set on the base plate to place lower positioning parts of different specifications. When in use, the lower positioning parts placed in the coaxial limiting hole 214 participate in the current pressing operation, and the unused lower positioning parts are placed in the non-coaxial limiting hole 215, which makes it convenient for the operator to replace the lower positioning parts.

[0044] In this embodiment of the utility model, the support member 211 can be four support columns. The bottom plate and the top plate are both rectangular, and the four support columns are respectively supported on the four corners of the bottom plate and the top plate, thereby forming a rectangular hollow mold frame, which is convenient for the operator to observe from different angles.

[0045] In embodiments of this utility model, the upper positioning member 230 and the moving rod 220 can be detachably connected. One implementation involves fixing a retaining spring component 270 to the lower end of the moving rod 220, with the upper positioning member 230 engaging with the retaining spring component 270. (See reference...) Figure 6 This connection structure allows operators to easily replace the positioning components.

[0046] Next, we will proceed through... Figure 5 , Figure 6 This section explains how to use the pressing device of this utility model.

[0047] Figure 5 This diagram illustrates the usage state of the handle pressing device according to this embodiment. Figure 6 This diagram illustrates a cross-sectional view of the handle pressing device in use according to this embodiment.

[0048] like Figure 5 As shown, a transducer is placed in the pressing device, with an upper positioning member defining the head of the transducer and a lower positioning member defining the tail of the transducer. Figure 6 As shown, the moving rod, upper positioning component, lower positioning component and the inner core of the transducer are on the same axis, which ensures uniform force during pressing. The inner core of the transducer head and the cable at the tail are not compressed. The transducer obtained after pressing can ensure overall consistency.
