Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a transducer handle protective sleeve and an ultrasonic transducer assembly. Background Technology

[0002] Existing scissor-type ultrasonic scalpels generally consist of a reusable transducer handle and a disposable blade. A screw is located at the front end of the transducer handle, which is detachably connected to the blade and drives the blade to vibrate at high frequency. Before use, the transducer handle and blade need to be assembled and then connected to the main unit. The main unit generates a high-frequency signal, which excites the transducer in the handle to convert electrical energy into ultrasonic vibrations. These vibrations are then transmitted to the blade via the screw to cut and coagulate soft tissue. Therefore, the screw connecting the transducer handle and blade needs to be protected when not in use to prevent damage.

[0003] In addition, the transducer handle is a reusable part. The transducer handle needs to be attached to and detached from the blade before and after surgery. The operation of attaching and detaching the transducer handle from the blade is relatively frequent. However, because the diameter of the transducer handle is relatively small, generally no more than two centimeters, it is difficult for the user to hold and is inconvenient to operate when attaching and detaching from the blade. Utility Model Content

[0004] The main purpose of this utility model is to provide a transducer handle protective sleeve and an ultrasonic transducer assembly, which aims to facilitate users in holding the transducer handle for disassembly and assembly operations, and also to protect the screw.

[0005] To achieve the above objectives, this utility model proposes a transducer handle protective sleeve. The transducer handle includes a housing, a screw passing through the front end of the housing, and a cable passing through the rear end of the housing. The protective sleeve is characterized by having a receiving cavity, through which the protective sleeve can be fitted over the outside of the screw and the front end of the housing; or through the receiving cavity, the protective sleeve can be fitted over the rear end of the housing and the cable.

[0006] In one embodiment, the receiving cavity includes a first sub-cavity and a second sub-cavity that are axially connected, wherein the inner diameter of the first sub-cavity is larger than the inner diameter of the second sub-cavity;

[0007] The front end of the housing is accommodated in the first sub-cavity, and the outside of the screw is accommodated in the second sub-cavity; or the rear end of the housing is accommodated in the first sub-cavity, and the cable is accommodated in the second sub-cavity.

[0008] In one embodiment, a stepped structure is formed at the connection between the first sub-cavity and the second sub-cavity. The stepped structure is used to abut against the end face of the front end of the housing facing the screw, or the stepped structure is used to abut against the end face of the rear end of the housing facing the cable, so as to restrict the axial movement of the protective sleeve.

[0009] In one embodiment, the protective sleeve has a notch that connects the receiving cavity to the external environment, and the notch extends through the protective sleeve along its axial direction.

[0010] In one embodiment, at least one end of the notch along the axial direction of the protective sleeve is provided with a chamfered structure or a rounded corner structure.

[0011] In one embodiment, the protective sleeve is flexible, and the outer wall of the protective sleeve is provided with a first anti-slip structure.

[0012] In one embodiment, the outer diameter of the protective sleeve first increases and then decreases along the axial direction from one end to the other.

[0013] In one embodiment, the depth of the first sub-cavity along the axial direction of the protective sleeve is greater than or equal to the depth of the second sub-cavity along the axial direction of the protective sleeve.

[0014] In one embodiment, the inner wall of the first sub-cavity is provided with a second anti-slip structure; and / or,

[0015] The inner diameter of the first sub-cavity is less than or equal to the outer diameter of the shell.

[0016] This utility model also proposes an ultrasonic transducer assembly, comprising:

[0017] Transducer handle; and,

[0018] The aforementioned transducer handle protective cover is fitted over the transducer handle.

[0019] The transducer handle protective sleeve of this utility model has a receiving cavity. When the protective sleeve is fitted over the outside of the screw and the front end of the housing through the receiving cavity, the protective sleeve is in a protective state, protecting the screw and housing, reducing the possibility of screw damage, and extending the service life of the transducer handle. When the protective sleeve is fitted over the outside of the housing through the receiving cavity, the protective sleeve is in a grip-assisting state, which helps the user hold the transducer handle. Because the overall diameter of the protective sleeve is larger after being fitted over the housing, it is easier for the user to hold, thus facilitating the assembly of the transducer handle with the cutting tool. A single protective sleeve achieves both screw protection and convenient assembly, simplifying the structure and reducing manufacturing costs. Attached Figure Description

[0035] This utility model proposes a protective cover for a transducer handle.

[0036] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the transducer handle protective sleeve provided by this utility model in the grip-assisting state. Figure 2 This is a schematic diagram showing the transducer handle protective sleeve in its protected state, as provided by this utility model. Figure 3 A cross-sectional view of an embodiment of the transducer handle protective sleeve provided by this utility model.

[0037] In one embodiment of this utility model, the transducer handle 200 includes a housing 210, a screw 220 passing through the front end of the housing 210, and a cable 230 passing through the rear end of the housing 210. The protective sleeve 100 is characterized by having a receiving cavity 110, through which the protective sleeve 100 can be fitted over the outside of the screw 220 and the front end of the housing 210; or through the receiving cavity 110, the protective sleeve 100 can be fitted over the outside of the rear end of the housing 210 and the cable 230.

[0038] The protective sleeve 100 in this invention is flexible and has a receiving cavity 110. When the protective sleeve 100 is fitted over the screw 220 and the front end of the housing 210 through the receiving cavity 110, it is in a protective state, protecting the screw 220 and the housing 210, reducing the possibility of damage to the screw 220, and extending the service life of the transducer handle 200. When the protective sleeve 100 is fitted over the housing 210 through the receiving cavity 110, it is in a grip-assisting state, helping the user to hold the transducer handle 200. Because the overall diameter of the protective sleeve 100 is relatively large after being fitted over the housing 210, it is easier for the user to hold, thus facilitating the assembly of the transducer handle 200 with the tool 300. The protective sleeve 100 achieves both protection for the screw 220 and ease of gripping for assembly, simplifying the structure and reducing manufacturing costs.

[0039] The protective case 100 is flexible by using an elastic material, such as silicone or rubber. The flexible protective case 100 can deform, making it easier to switch between a protective state and a grip-assisting state.

[0040] In one embodiment, the receiving cavity 110 includes a first sub-cavity 111 and a second sub-cavity 112 that are connected along the axial direction, wherein the inner diameter of the first sub-cavity 111 is larger than the inner diameter of the second sub-cavity 112;

[0041] The front end of the housing 210 is accommodated in the first sub-cavity 111, and the screw 220 is accommodated in the second sub-cavity 112; or the rear end of the housing 210 is accommodated in the first sub-cavity 111, and the cable 230 is accommodated in the second sub-cavity 112.

[0042] Reference Figures 1 to 3In an embodiment of this utility model, the receiving cavity 110 includes a first sub-cavity 111 and a second sub-cavity 112. The inner diameter of the first sub-cavity 111 corresponds to the outer diameter of the housing 210, and the inner diameter of the second sub-cavity 112 corresponds to the outer diameter of the screw 220. The inner diameter of the first sub-cavity 111 is larger than the inner diameter of the second sub-cavity 112. When the protective sleeve 100 is in the protected state, the larger first sub-cavity 111 is fitted onto the outside of the front end of the housing 210, and the smaller second sub-cavity 112 is fitted onto the outside of the screw 220, ensuring that the protective sleeve 100 is securely fitted onto the front end of the entire transducer handle 200, thereby improving the protection of the screw 220. When the protective sleeve 100 is in the grip-assisted state, the larger first sub-cavity 111 is fitted outside the rear end of the housing 210, and the smaller second sub-cavity 112 is fitted outside the cable 230. This is compatible with the existing transducer handle 200 structure and makes it easier for the user to grip the protective sleeve 100 and the transducer handle 200.

[0043] Specifically, in this embodiment, the cable 230 includes a conductor 231 and a sheath 232. The sheath 232 passes through the rear end of the housing 210, the conductor 231 passes through the sheath 232, and the protective sleeve 100 is sleeved on the outside of the sheath 232 through the second sub-cavity 112.

[0044] In one embodiment, a stepped structure 140 is formed at the connection between the first sub-cavity 111 and the second sub-cavity 112. The stepped structure 140 is used to abut against the end face of the front end of the housing 210 facing the screw 220, or the stepped structure 140 is used to abut against the end face of the rear end of the housing 210 facing the cable 230, so as to restrict the axial movement of the protective sleeve 100.

[0045] Reference Figures 1 to 3 In this embodiment of the invention, a stepped structure 140 is formed at the connection between the first sub-cavity 111 and the second sub-cavity 112. When the protective sleeve 100 is in the protected state, the stepped structure 140 abuts against the end face of the housing 210 facing the screw 220, restricting the protective sleeve 100 from moving along its own axial direction towards the rear end of the housing 210. When the protective sleeve 100 is in the gripping state, the stepped structure 140 abuts against the end face of the housing 210 facing the cable 230, restricting the protective sleeve 100 from moving along its own axial direction towards the front end of the housing 210. Through the contact between the stepped structure 140 and the end face of the housing 210, the protective sleeve 100 is positioned, ensuring the accuracy of the installation position of the protective sleeve 100 and improving the protective and gripping effects of the protective sleeve 100.

[0046] In one embodiment, the protective sleeve 100 is provided with a notch 120, which connects the receiving cavity 110 and the external environment, and the notch 120 extends through the protective sleeve 100 along its axial direction.

[0047] Reference Figures 4 to 5In this embodiment of the present invention, a notch 120 is provided on the side wall of the protective sleeve 100. The notch 120 extends through the protective sleeve 100 along its axial direction, making the radial cross section of the protective sleeve 100 C-shaped. When the protective sleeve 100 is in the gripping state, a cable 230 is connected to the rear end of the transducer. The protective sleeve 100 with the notch 120 does not need to be fitted with the cable 230 along the end of the cable 230 away from the housing 210 and then slide along the cable 230 to the rear end of the housing 210. It can directly fit onto the rear end of the housing 210 through the notch 120 by its own deformation ability. Similarly, when removing it from the gripping state, the protective sleeve 100 can also be removed directly through the notch 120, reducing the steps of disassembling and assembling the protective sleeve 100 and improving the convenience of using the protective sleeve 100. When the protective sleeve 100 is in the protected state, the protective sleeve 100 covers the front end of the housing 210 and the screw 220. When the entire ultrasonic transducer assembly is subjected to high-temperature sterilization, the notch 120 makes the structure of the protective sleeve 100 more open, so that the high-temperature sterilization steam can more easily enter the cavity 110 and improve the sterilization effect.

[0048] In one embodiment, at least one end of the notch 120 along the axial direction of the protective sleeve 100 is provided with a chamfered structure or a rounded corner structure 130.

[0049] Reference Figure 5 In this embodiment of the invention, along the axial direction of the protective sleeve 100, one or both ends of the notch 120 are provided with a chamfered structure, or a rounded corner structure 130, so that the axial length of the protective sleeve 100 is narrower closer to the notch 120, and the area around the notch 120 is more prone to deformation, thereby further improving the convenience of disassembly and assembly. Specifically, in this embodiment, a rounded corner structure 130 is provided at the end of the notch 120 near the first sub-cavity 111.

[0050] In one embodiment, the outer wall of the protective sleeve 100 is provided with a first anti-slip structure 150.

[0051] Reference Figure 4 In an embodiment of this utility model, a first anti-slip structure 150 is provided on the outer wall of the protective cover 100. The first anti-slip structure 150 can be raised or grooved in the form of vertical lines, horizontal lines, interlaced lines, knurling, etc., thereby increasing the friction between the protective cover 100 and the user's hand, preventing the user from slipping when holding the protective cover 100, and improving the gripping effect of the protective cover 100.

[0052] In one embodiment, the outer diameter of the protective sleeve 100 increases and then decreases axially from one end to the other.

[0053] Reference Figure 3In the embodiments of this utility model, the outer diameter of the protective sleeve 100 increases and then decreases along the axial direction from one end to the other, making the shape of the protective sleeve 100 close to a spindle shape, which is more in line with the gripping habits of the human hand, thereby improving the convenience and comfort of the user's grip.

[0054] In one embodiment, the depth of the first sub-cavity 111 along the axial direction of the protective sleeve 100 is greater than or equal to the depth of the second sub-cavity 112 along the axial direction of the protective sleeve 100.

[0055] Reference Figure 3 In the embodiments of this utility model, the depth of the first sub-cavity 111 along the axial direction of the protective sleeve 100 is not less than the depth of the second sub-cavity 112 along the axial direction of the protective sleeve 100. That is to say, in the protected state, the length of the protective sleeve 100 outside the front end of the housing 210 is not less than the length outside the screw 220, thereby improving the firmness of the connection between the protective sleeve 100 and the transducer handle 200 and reducing the possibility of the protective sleeve 100 falling off.

[0056] In one embodiment, the inner wall of the first sub-cavity 111 is provided with a second anti-slip structure; and / or,

[0057] The inner diameter of the first sub-cavity 111 is less than or equal to the outer diameter of the shell 210.

[0058] In an embodiment of this utility model, the inner wall of the first sub-cavity 111 is provided with a second anti-slip structure (not shown in the figure). The second anti-slip structure can be raised or grooved in the form of vertical lines, horizontal lines, interlaced lines, knurling, etc., thereby increasing the friction between the protective sleeve 100 and the outer wall of the housing 210, thereby further improving the firmness of the protective sleeve 100 after it is fitted onto the outside of the transducer handle 200 and reducing the possibility of the protective sleeve 100 falling off. In addition, when the protective sleeve 100 is in the gripping state, the second anti-slip structure can prevent relative sliding between the protective sleeve 100 and the transducer handle 200, making it easier and faster for the user to assemble the transducer handle 200 with the cutter 300.

[0059] In the embodiments of this utility model, in the natural state, the inner diameter of the first sub-cavity 111 is not greater than the outer diameter of the shell 210. The protective sleeve 100 is fitted onto the outside of the shell 210 by its own deformation ability. The elastic force generated by the deformation makes the protective sleeve 100 tightly wrap the shell 210, thereby improving the firmness of the connection between the protective sleeve 100 and the transducer handle 200 and reducing the possibility of the protective sleeve 100 falling off.

[0060] This utility model also proposes an ultrasonic transducer assembly, comprising:

[0061] Transducer handle 200: and,

[0062] The aforementioned transducer handle protective sleeve 100 is fitted over the transducer handle 200.

[0063] The specific structure of the protective sleeve 100 of the transducer handle 200 is as described in the above embodiments. Since this ultrasonic transducer assembly adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0064] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
