Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to an adapter for an ultrasonic surgical aspiration device. Background Technology

[0002] Ultrasonic surgical scalpels have been widely used for over 20 years. They utilize transducers to convert electrical energy into acoustic energy. Through the high-frequency vibration of the transducer and the amplification by the amplitude transformer, ultrasonic surgical scalpels produce cavitation, thermal, and mechanical effects.

[0003] Ultrasonic scalpels have wide applications in various surgical fields, such as laparoscopic surgery, thoracic surgery, and neurosurgery. Their high precision, low invasiveness, and rapid recovery make them an essential tool in modern surgery. With the continuous development of medical technology, ultrasonic scalpels will continue to play a vital role in the field of surgery, safeguarding patients' health.

[0004] Traditional ultrasonic scalpels are divided into straight-blade scalpels and curved-blade scalpels according to the different angles of the scalpel part relative to the handle part. By bending or processing the scalpel head into a curved shape, they can meet the needs of doctors in surgery. This makes the product difficult to manufacture, costly, and inconsistent.

[0020] To better explain and facilitate understanding of this utility model, the following description is provided in conjunction with the appendix. Figure 1-2 This utility model will be described in detail through specific embodiments. In this document, directional terms such as "upper" and "lower" are used in conjunction with other directional terms. Figure 1 The orientation is used as a reference, and "front" is Figure 1 From the center to the left, "back" is Figure 1 The direction from the center to the right.

[0021] Example 1:

[0022] Reference Figure 1 and Figure 2 An embodiment of this utility model provides an ultrasonic surgical aspiration device adapter, including a handle assembly 1 and a blade module 2 detachably connected to the front end of the handle assembly 1. The front end of the handle assembly 1 is formed with a variety of different angles so that the ultrasonic scalpel can be formed with a variety of different angles.

[0023] The handle assembly 1 includes a handle 11 and a connecting assembly 12; the handle 11 includes a handle 111 and an ultrasonic transducer 112 located within the handle 111; the blade module 2 includes a blade housing 21 and a scalpel 22 located within the blade housing 21; the connecting assembly 12 includes an intermediate housing 121 and a connector 122 located within the intermediate housing 121; the handle 111, the intermediate housing 121 and the blade housing 21 are connected in sequence, and at least the intermediate housing 121 is detachably connected to the blade housing 21; the two axial ends of the connector 122 are respectively connected to the output end of the ultrasonic transducer 112 and the input end of the scalpel 22, and at least the end of the connector 122 near the scalpel 22 is detachably connected to the scalpel 22.

[0024] In this embodiment, the design of this ultrasonic surgical aspiration device adapter is very flexible and multifunctional, designed to adapt to different surgical scenarios and operational needs, that is, to enable the scalpel 22 to switch between a straight blade and a curved blade at different angles.

[0025] The handle 111 is the main gripping part of the scalpel 22, and its design must conform to ergonomics to ensure that the surgeon can maintain a comfortable and stable grip during prolonged surgery. Built into the handle 111, it is responsible for converting electrical energy into high-frequency ultrasonic vibration energy. This vibration energy is transmitted to the scalpel 22 through the connecting component 12 to cut or coagulate tissue, reducing bleeding and damage during surgery.

[0026] The intermediate housing 121 serves as a bridge connecting the handle 111 and the blade module 2. The intermediate housing 121 needs to have a certain strength and stability to ensure its protective performance for the connector 122, the ultrasonic transducer 112 and the scalpel 22.

[0027] The connector 122, located within the intermediate housing 121, is ingeniously designed. One end is tightly connected to the output of the ultrasonic transducer 112, while the other end matches the input of the scalpel 22. The design of the connector 122 allows ultrasonic vibration energy to be transmitted to the scalpel 22 with low loss, thereby facilitating efficient surgical procedures.

[0028] The blade housing 21 protects the scalpel 22, thereby improving the reliability of the ultrasonic surgical suction device adapter. The scalpel 22, located within the blade housing 21, is the component used for cutting tissue.

[0029] When it is necessary to change the angle of the blade module 2, the entire handle assembly 1, consisting of the intermediate housing, blade handle, and connector, is replaced. Specifically, when the product of this patent is sold, it may include the aforementioned handle assembly 1 with various angle models, as well as various blades, facilitating the user's operation of changing the blade module. This allows surgical blades of different angles to share the blade module 2, thereby reducing the overall cost of the ultrasonic surgical suction device adapter and enabling more efficient and precise surgical operations, greatly improving the flexibility of the ultrasonic surgical suction device adapter.

[0030] Alternatively, replacing the connecting component 12 alone can also achieve the purpose of adjusting the blade angle of the ultrasonic surgical aspiration device adapter. This replacement method allows the ultrasonic surgical aspiration device adapter to share not only the blade module 2 but also the blade handle when adjusting the angle of the blade module 2, further reducing the overall cost. When this type of ultrasonic surgical aspiration device adapter is manufactured and sold, multiple sets of connecting components 12 with different angle models can be included. However, compared to the previous replacement method, this replacement method is more difficult to operate.

[0031] Specifically, the blade housing 21 includes a front housing 211 and a rear housing 212; the handle 111, the middle housing 121, the rear housing 212 and the front housing 211 are connected in sequence, and at least the middle housing 121 and the rear housing 212 are detachably connected.

[0032] Specifically, the rear housing 212 is set at one angle, the middle housing 121 and the connector 122 are set at multiple angles that match the angle, and the rear housing 212 is adaptable to each type of connector 122 and middle housing 121.

[0033] The intermediate housing 121 serves as the connecting link between the handle 111 and the rear housing 212. The intermediate housing 121 is designed to have multiple angles. These different angles allow the surgeon to select the most suitable angle model of the handle assembly 1 according to the specific requirements of the surgical site and surgical path, so as to achieve optimal positioning and operation of the scalpel 22.

[0034] The connector 122 is also designed to match the angle of the intermediate housing 121 at multiple angles. The connector 122 is responsible for accurately transmitting the vibration energy generated by the ultrasonic transducer 112 to the scalpel 22.

[0035] The handle 111 and the intermediate housing 121, the intermediate housing 121 and the rear housing 212, and the rear housing 212 and the front housing 211 are all connected by an interference fit of sealing rings to ensure the sealing performance of the ultrasonic surgical suction device adapter and improve its reliability.

[0036] Example 2:

[0037] Reference Figure 1 and Figure 2 In addition to possessing all the technical solutions of any of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0038] The connector 122 includes a middle portion 1221 and connecting portions 1222 connected to both axial ends of the middle portion 1221; a connecting port extends from the front end of the middle housing 121, and the connecting port can have a first included angle α with respect to the axis of the ultrasonic transducer 112; one connecting portion 1222 is coaxial with the middle portion 1221 and connected to the scalpel 22, and the other connecting portion 1222 extends at an angle to the axis of the middle portion 1221 and connects to the output end of the ultrasonic transducer 112, the included angle being equal to the first included angle α;

[0039] The intermediate housing 121 includes a straight housing and an elbow housing, and the connector 122 includes a straight head and an elbow. When the intermediate housing 121 and the connector 122 are respectively set as a straight housing and a straight head, the first included angle α is equal to 0°. When the intermediate housing 121 and the connector 122 are respectively set as an elbow housing and an elbow, the first included angle α is between 0° and 90°.

[0040] In this embodiment, the connector 122 includes a middle portion 1221 and two connecting portions 1222. The connecting portion 1222, which is connected to the scalpel 22, is coaxial with the middle portion 1221 and is directly connected to the scalpel 22. Because it is coaxial with the middle portion 1221, it can ensure that vibration energy is directly transmitted to the scalpel 22 with minimal loss, thereby achieving efficient surgical operation.

[0041] Another connecting part 1222 has a certain angle with the axis of the middle part 1221. This angle is equal to the angle of the connecting port extending from the front end of the middle shell 121. In this way, the angle matching between the connecting head 122 and the middle shell 121 is achieved, so that the working condition where the middle shell 121 and the connecting head 122 have an angle will not affect the normal transmission of vibration energy.

[0042] This embodiment shows the matching of the elbow connector 122 and the elbow intermediate housing 121, and also shows the matching of the straight connector 122 and the straight intermediate housing 121, so that the scalpel 22 can be flexibly switched to the form of a straight or elbow handle assembly 1 according to the doctor's needs, and can be operated at a more flexible angle.

[0043] In summary, this ultrasonic surgical aspiration device adapter achieves efficient transmission of vibration energy and flexible operation of the scalpel 22. Surgeons can select appropriate angle combinations according to surgical needs to achieve the best surgical results.

[0044] Example 3:

[0045] Reference Figure 1 and Figure 2 In addition to possessing all the technical solutions of any of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0046] The ultrasonic transducer 112 includes an amplitude transformer 1121, the front end of which forms the output end of the ultrasonic transducer 112. A first connecting hole is provided at the front end of the amplitude transformer 1121, and a second connecting hole is provided at the rear end of the scalpel 22. Two connecting parts 1222 are connected to the first connecting hole and the second connecting hole respectively. The outer diameter of the middle part 1221 is larger than the outer diameter of the two connecting parts 1222, so that an abutting surface is formed at the end of the connecting part 1222, and the two abutting surfaces abut against the front end of the amplitude transformer 1121 and the rear end of the scalpel 22 respectively.

[0047] In this embodiment, the amplitude transformer 1121 is part of the ultrasonic transducer 112, and its front end forms the output end of the ultrasonic transducer 112. The amplitude transformer 1121 is designed not only to transmit vibration energy, but also to amplify or focus this energy through changes in its shape to meet the needs of surgical operations.

[0048] The first connecting hole is located at the front end of the amplitude transformer 1121, i.e., the output end of the ultrasonic transducer 112. This hole is used to receive the connecting part 1222 in the connector 122 that is connected to the ultrasonic transducer 112. The second connecting hole is located at the rear end of the scalpel 22. This hole is used to receive the connecting part 1222 in the connector 122 that is connected to the scalpel 22.

[0049] The outer diameter of the middle portion 1221 of the connector 122 is designed to be larger than the outer diameter of the two connecting portions 1222. This design creates a distinct abutment surface at the ends of the connecting portions 1222. The two abutment surfaces respectively abut the front end of the amplitude transformer 1121 and the rear end of the scalpel 22. This design not only ensures a tight connection between the connector 122 and the ultrasonic transducer 112 and the scalpel 22, but also transmits vibration energy through the abutment surfaces. The presence of the abutment surfaces also increases the stability of the connection, preventing loosening or detachment due to vibration.

[0050] Furthermore, the connection part 1222 and the corresponding first connection hole or second connection hole are threaded to ensure the tightness of the connection and the reliability of vibration energy transmission, while also ensuring the ease of disassembly and assembly of the connector 122.

[0051] The ultrasonic transducer 112 also includes a piezoelectric ceramic disposed on the amplitude transformer 1121 for generating high-frequency vibration.

[0052] Example 4:

[0053] Reference Figure 1 and Figure 2 In addition to possessing all the technical solutions of any of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0054] The amplitude rod 1121, connector 122 and scalpel 22 are all axially continuous structures to form interconnected channels 3; channels 3 can be used as heat dissipation channels and media transport channels.

[0055] The design of channel 3 itself reduces the overall weight of connector 122, amplitude transformer 1121, and scalpel 22, which is beneficial for the lightweight design of the ultrasonic surgical aspiration equipment adapter. The design of channel 3 also gives these three components a larger surface area, which is beneficial for heat dissipation and improves the efficiency of the ultrasonic surgical aspiration equipment adapter.

[0056] Meanwhile, channel 3 can be used in conjunction with a negative pressure device for drainage. That is, the end of channel 3 near the ultrasonic transducer 112 is connected to a negative pressure device so that during the operation, the tissue cut during the operation can be removed through the inlet of channel 3 at the front end of the scalpel 22, and the medium fluid used to rinse the surgical site can also be suctioned away to ensure the cleanliness of the surgical site and improve the safety of the operation.

[0057] At the same time, when the medium flows through channel 3, it can also carry away some of the heat from the amplitude rod 1121, connector 122 and scalpel 22, thereby achieving further heat dissipation of the three and thus helping to further improve the efficiency of the ultrasonic surgical suction equipment adapter.
