Currently, ultrasonic surgical instruments utilize ultrasonic energy, i.e., ultrasonic vibration, to treat tissue. Typically, the ultrasonic vibrations are provided by an ultrasonic transducer. The efficiency of the ultrasonic transducer, which in turn is affected by the operating temperature of the ultrasonic transducer, affects the operation of the end effector. When the temperature of the ultrasonic transducer exceeds half of the curie temperature, the efficiency of the ultrasonic transducer can be rapidly reduced, and the use performance is affected.

Therefore, the utility model provides a novel ultrasonic transducer 100, this ultrasonic transducer 100 can provide the required vibration of work for the apparatus body of ultrasonic surgical instrument, can also guarantee the temperature of self simultaneously, avoids exceeding the curie temperature, guarantees ultrasonic transducer 100's work efficiency, and then guarantees ultrasonic surgical instrument's performance, guarantees the security of operation process, reduces the risk that the operation in-process brought because of ultrasonic transducer 100 efficiency. The specific structure of the ultrasonic transducer 100 is described in detail below.

Referring to fig. 1-4, in one embodiment, an ultrasonic transducer 100 includes a mounting housing 110 and a transducer assembly 120. The mounting case 110 has a receiving cavity, and an air inlet hole 113 and an air outlet hole 114 communicating with the receiving cavity. The transducer assembly 120 is disposed in the accommodating cavity, and encloses with the mounting housing 110 to form a flow channel 115, and the flow channel 115 communicates with the air inlet hole 113 and the air outlet hole 114 for air to flow through.

The installation shell 110 is a protection shell of the ultrasonic transducer 100, and protects each part of the ultrasonic transducer 100 through the installation shell 110, so that medical staff are prevented from electric shock, external sundries are prevented from entering the ultrasonic transducer 100, and the service performance of the ultrasonic transducer 100 is ensured. The transducer assembly 120 is a main structure of the ultrasonic transducer 100, and is capable of converting energy, converting a pumping signal of the ultrasonic generator into a mechanical vibration signal, that is, converting electrical energy into mechanical energy and outputting the mechanical energy.

The mounting housing 110 has a hollow receiving cavity, and the transducer assembly 120 is mounted in the receiving cavity of the mounting housing 110. One end of the mounting shell 110 is provided with an opening, the transducer assembly 120 is arranged behind the mounting shell 110, the output end of the transducer assembly 120 is at least partially exposed out of the mounting shell 110, the output end of the transducer assembly 120 is connected with an ultrasonic energy transmission component of the ultrasonic surgical instrument, and the ultrasonic energy transmission component of the transducer assembly 120 transmits a mechanical vibration signal to the instrument body, so that the instrument body performs corresponding operation.

The air inlet hole 113 and the air outlet hole 114 are respectively communicated to the installation cavity of the installation shell 110. Furthermore, when the transducer assembly 120 is disposed on the mounting housing 110, a space is formed between the transducer assembly 120 and the inner wall of the mounting housing 110, which is the flow channel 115. The flow passage 115 is a part of the installation chamber and can communicate the air inlet hole 113 with the air outlet hole 114.

Thus, external air flow can enter the circulation channel 115 through the air inlet hole 113, and when the transducer assembly 120 generates a large amount of heat during operation, the air flow in the circulation channel 115 can exchange heat with the heat exchange assembly during the flowing process to absorb the heat of the transducer assembly 120, so as to reduce the operating temperature of the transducer assembly 120. The heat absorbed can continue to flow along the flow channel 115 and be discharged from the outlet hole 114. Thus, the external air flow can continuously enter through the air inlet hole 113 and is discharged from the air outlet hole 114 after cooling the transducer assembly 120, so that the working temperature of the transducer assembly 120 is reduced, and the efficiency of the transducer assembly 120 is ensured.

Optionally, there is a certain distance between the inlet hole 113 and the outlet hole 114 along the axial direction of the transducer assembly 120. This ensures that the transducer assembly 120 is effectively cooled by the ambient air flow. Optionally, the distance between the inlet aperture 113 and the outlet aperture 114 is less than or equal to the axial length of the transducer assembly 120. Optionally, the inlet aperture 113 corresponds to an end of the transducer assembly 120 remote from the ultrasonic energy delivery member, and the outlet aperture 114 corresponds to a central region of the transducer assembly 120 or an end of the transducer assembly 120 connected to the ultrasonic energy delivery member.

Optionally, the transducer assembly 120 further comprises a mounting flange 124, the mounting flange 124 being disposed about the outside of the horn body 121 for securing the horn body 121 to the inner wall of the mounting housing 110. With the mounting flange 124, the transducer section 122 and the outer wall of the horn body 121 can be spaced from the inner wall of the mounting housing 110 to form the flow channel 115. Thus, after entering the flow channel 115 through the air inlet 113, the outside air flow can exchange heat with the transduction group and the horn body 121, thereby reducing the temperature of the transduction group and the horn body 121.

In one embodiment, the transducer 122 includes a plurality of ceramic sheets 1221, and positive and negative electrode sheets 1222 and 1223 disposed between the ceramic sheets 1221, the plurality of ceramic sheets 1221 being stacked at one end of the horn body 121 in the axial direction and disposed away from the ultrasonic energy transmission member, the positive and negative electrode sheets 1222 and 1223 being disposed alternately in the ceramic sheets 1221.

The cooling member 130 can provide power for the airflow to accelerate the airflow in the flow channel 115, so as to ensure the cooling effect of the airflow on the transducer assembly 120.

When the ultrasonic transducer 100 is operated, the cooling member 130 can operate, the cooling member 130 can provide a suction force to suck the airflow in the flow channel 115, so that the external airflow can rapidly enter the flow channel 115 of the mounting housing 110 to cool the energy conversion assembly 120, and the airflow after absorbing heat can accelerate to flow out from the air outlet 114 under the action of the cooling member 130. After the cooling component 130 accelerates the airflow to flow, the transducer assembly 120 can be rapidly cooled by the airflow, and the cooling effect of the transducer assembly 120 is ensured.

Optionally, the ultrasound transducer 100 further comprises a main cable, which supplies power and transmits signals for the operation of the ultrasound transducer 100. Optionally, the main cable includes a positive cable capable of electrically connecting with the positive tab 1222 of the transducer assembly 120, a negative cable capable of electrically connecting with the negative tab 1223 of the transducer assembly 120, a power supply cable, and a signal wire. The power supply cable can electrically connect the cooling part 130 to supply power to the cooling part 130 so that the cooling part 130 operates. The signal wire is electrically connectable with an instrument body of the ultrasonic surgical instrument to transmit signals to the instrument body.

Illustratively, the intake holes 113 are on the mounting case 110 and are located at the side of the cooling part 130. In this way, the cooling member 130 can generate a suction force during operation, so that an external air flow can enter the flow channel 115 through the air inlet hole 113, and the air flow is conveyed through the flow channel 115 through the cooling member 130 to cool the conveying assembly, and the air flow after absorbing heat is discharged through the air outlet hole 114.

Of course, in other embodiments of the present invention, the cooling member 130 may be disposed between the air inlet hole 113 and the air outlet hole 114. Alternatively, the positions of the inlet holes 113 and the outlet holes 114 may be interchanged.

The second housing 112 is mounted at the other end opening of the first housing 111, and the other end opening of the first housing 111 is closed by the second housing 112.

Because the cooling member 130 is disposed at the end of the transducer assembly 120 away from the ultrasonic energy transmission member, the original length of the ultrasonic transducer 100 is increased, and therefore, the second housing 112 is added at the rear end of the first housing 111, and the cooling member 130 is wrapped by the second housing 112, thereby preventing the cooling member 130 from being exposed. Moreover, the main cable routing of the ultrasonic transducer 100 can also be facilitated in the second housing 112.
