If tissue needs to be obtained for pathological examination, specialized sampling instruments such as biopsy forceps or surgical scissors must be used midway through the procedure.

[0004] Therefore, a high-frequency electrosurgical unit with an ultrasonic probe is proposed to solve the problems mentioned above. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: It includes an operating part, one end of which is connected to a connecting cable, and the other end of the operating part away from the connecting cable is fixedly connected to a protective cylinder. An adjustment mechanism is connected inside the protective cylinder. A connecting pipe is provided on the side wall of the operating part. The adjustment mechanism includes an outer cylinder, which is rotatably connected inside the protective cylinder. An ultrasonic probe is connected to the side wall of the outer cylinder via a connecting assembly. An inner cylinder is slidably connected inside the outer cylinder. An electromagnetic spring is fixedly connected to the space inside the outer cylinder. The other end of the electromagnetic spring is fixedly connected to an upper ring, and the lower end of the upper ring is fixedly connected to the inner cylinder. An inner rod is fixedly connected inside the outer cylinder, and a delivery bag is fixedly connected to the top of the inner rod. A contact bag is fixedly connected to the lower end of the inner side wall of the inner cylinder, and the contact bag communicates with the delivery bag via a delivery pipe.

[0006] In one possible implementation, a motor is bolted inside the protective cylinder. The motor's output shaft drives a drive gear to mesh with a driven gear. The driven gear is fixedly connected to the outer cylinder. A connecting rod passes through the inner shaft of the driven gear, and the top of the connecting rod is connected to the protective cylinder.

[0007] In one possible implementation, the bottom of the connecting rod is connected to the drive assembly.

[0008] In one possible implementation, the drive assembly includes a contact ring, with its top connected to a connecting rod and a guide rod fixedly connected to its bottom.

[0009] In one possible implementation, a bidirectional lead screw is rotatably connected to the side wall of the guide rod, and the bidirectional lead screw is connected to a drive motor, which is connected to the side wall of the guide rod.

[0010] In one possible implementation, the bidirectional lead screw is internally threaded to the connecting plate, and the connecting plate is slidably connected to the guide rod.

[0011] In one possible implementation, the bottom of the connecting plate is fixedly connected to the blade body, and the connecting plate and the blade body are provided in two sets. The blade body is concave, and the side walls of the two sets of blade bodies that are close to each other are provided with sharp ends.

[0012] In one possible implementation, the blade body is hollowed out to form a channel, which is connected to a suction hole located on the side wall of the blade body.

[0013] In one possible implementation, the other end of the channel is connected to the conveying pipe, the other end of the conveying pipe passes through the contact ring and communicates with the channel inside the connecting rod, and the channel inside the connecting rod is connected to the connecting pipe.

[0014] In one possible implementation, the connecting assembly includes a fixed cylinder, which is threaded to the side wall of the outer cylinder via a lead screw. A movable cylinder is movably connected inside the fixed cylinder. A first connecting rod is rotatably connected to the side wall of the movable cylinder via a torsion spring. The other end of the first connecting rod is rotatably connected to a second connecting rod via a torsion spring. The other end of the second connecting rod is rotatably connected to an ultrasonic probe via a torsion spring.

[0015] Compared with the prior art, the present invention provides a high-frequency electrosurgical unit with an ultrasonic probe, which has the following beneficial effects: 1. In this invention, the ultrasonic probe is fixed to the side wall of the outer cylinder. The outer cylinder is rotated as a whole by a motor, a drive gear and a driven gear, so that the circumferential position of the ultrasonic probe in the operating part can be adjusted. Two sets of concave blades are opened and closed by a bidirectional lead screw. The sharp end can squeeze and cut the tissue, and the cut sample is completely preserved in the concave space inside the blade body, without the need for other instruments to collect the tissue.

[0016] 2. During the treatment process, the present invention utilizes external negative pressure to form a directional airflow channel through the suction hole, delivery tube and connecting tube on the blade, which can efficiently remove harmful smoke and odors generated by electrosurgery and maintain a clear surgical field; continuous suction after surgery or between surgeries, with airflow flowing through the surface and interior of the blade, significantly accelerates the cooling of the blade.

[0017] 3. In this invention, after surgery, the inner cylinder is driven to move downward by an electromagnetic spring, and the delivery bag is squeezed to expand the contact bag. The expanded rough inner surface tightly adheres to the surface of the blade. With the help of a motor, the outer and inner cylinders rotate. The rough structure of the contact bag can rub and clean the surface of the blade, effectively removing the adhering material. The electromagnetic spring can control the inner cylinder to move up and down to achieve the contact position between the contact bag and the blade.

[0018] 4. After cleaning is completed, the inner cylinder continues to move down to the lowest position. The expanded contact bladder completely fills the gap between the bottom of the inner cylinder and the blade body, forming a sealed encapsulation cavity. The blade body is completely sealed between the inner cylinder and the outer cylinder, effectively preventing accidental punctures to the operator or assistant after the operation, while avoiding environmental pollution from residual tissue on the blade body.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1 - Figure 2 In this embodiment, a high-frequency electrosurgical unit with an ultrasonic probe includes an operating unit 1. One end of the operating unit 1 is connected to a connecting cable 2. During treatment, the electrosurgical unit is controlled by a foot switch or a button on the operating unit 1 to energize the blade 485. The blade 485 then contacts the tissue to perform a coagulation operation. Specifically, the other end of the operating unit 1 away from the connecting wire 2 is fixedly connected to a protective cylinder 3. An adjustment mechanism 4 is connected inside the protective cylinder 3. Before use, the connecting wire 2 at the end of the operating unit 1 is first electrically and pneumatically connected to the external electrosurgical unit, negative pressure suction device and control pedal. At the same time, the ultrasound probe 42 fixedly connected to the side wall of the outer cylinder 41 establishes a communication connection with the external ultrasound unit through its built-in wireless module for real-time acquisition of tissue images. Please see Figure 1 - Figure 2 A connecting pipe 5 is provided on the side wall of the operating part 1, and a one-way valve is provided inside the connecting pipe 5. Specifically, during the treatment process, when smoke is generated, the air in the connecting pipe 5 is drawn out, and the connecting pipe 5 drives the air in the delivery pipe 487 to be drawn out. The delivery pipe 487 draws the air in the suction hole 486 area through the channel 4861. The suction hole 486 draws the smoke generated in the treatment area inward to the connecting pipe 5 and transmits it outward to the outside. After subsequent use, the air flowing in the suction hole 486 area can accelerate the heat dissipation speed of the blade body 485 area. Please see Figure 3 - Figure 4 The adjustment mechanism 4 includes an outer cylinder 41, which is rotatably connected inside the protective cylinder 3. An ultrasonic probe 42 is connected to the side wall of the outer cylinder 41 through a connecting assembly. The ultrasonic probe 42 can be connected to an external ultrasonic host through an internal cable or wireless module. When in use, a coupling agent can be applied to the surface of the user's detection area beforehand, and then the ultrasonic probe 42 can be attached to the skin for detection. More specifically, the connecting assembly includes a fixed cylinder 421, which is threaded to the side wall of the outer cylinder 41 via a lead screw. A movable cylinder 422 is movably connected inside the fixed cylinder 421. A first connecting rod 423 is rotatably connected to the side wall of the movable cylinder 422 via a torsion spring. The other end of the first connecting rod 423 is rotatably connected to a second connecting rod 424 via a torsion spring. The other end of the second connecting rod 424 is rotatably connected to an ultrasonic probe 42 via a torsion spring. The movable cylinder 422 can roll freely within the fixed cylinder 421, so that when the operating part 1 is tilted, the movable cylinder 422 can also move within the fixed cylinder 421, so that the ultrasonic probe 42 will not tilt along with the operating part 1. When the ultrasound probe 42 is subjected to force, the position of the ultrasound probe 42 can be adjusted by the rotation of the first link 423 and the second link 424, so that the ultrasound probe 42 can come into contact with the skin.

[0023] In the initial state, the electromagnetic spring is not energized, the contact bladder 434 is in an expanded state, and the two sets of blades 485 are in a closed state that is close to each other under the action of the drive component 48, and are stored in the protective cylinder 3. Medical staff hold the operating part 1 and move the device to the surgical area. Specifically, an inner cylinder 43 is slidably connected inside the outer cylinder 41, and an electromagnetic spring is fixedly connected inside the outer cylinder 41. The other end of the electromagnetic spring is fixedly connected to the upper ring 431. The electromagnetic spring can drive the upper ring 431 to move up and down. When the upper ring 431 moves, it applies pressure to the lower delivery bag 433. The delivery bag 433 delivers air to the contact bag 434, causing the contact bag 434 to expand. The lower end of the upper ring 431 is fixedly connected to the inner cylinder 43. An inner rod 432 is fixedly connected inside the outer cylinder 41, and a delivery bag 433 is fixedly connected to the top of the inner rod 432. Specifically, a contact bladder 434 is fixedly connected to the lower end of the inner wall of the inner cylinder 43, and the contact bladder 434 is connected to the delivery bladder 433 through a delivery pipe; Specifically, the surface of the contact sac 434 is rough; Please see Figure 3 - Figure 4 A motor 45 is bolted inside the protective cylinder 3. The output shaft of the motor 45 drives the drive gear 44 to mesh with the driven gear 46. The output shaft of the motor 45 is fixedly connected to the drive gear 44. Specifically, the driven gear 46 is fixedly connected to the outer cylinder 41. When the driven gear 46 is rotated under force, it can also drive the protective cylinder 3 to rotate together. The inner shaft of the driven gear 46 passes through a connecting rod 47, and the top of the connecting rod 47 is connected to the protective cylinder 3. Please see Figure 5 - Figure 8 The bottom of the connecting rod 47 is connected to the drive assembly 48; Please see Figure 5 - Figure 8 The drive assembly 48 includes a contact ring 481. The top of the contact ring 481 is connected to the connecting rod 47, providing a space for the contact ring 481 to be installed and fixed. A guide rod 482 is fixedly connected to the bottom of the contact ring 481. A bidirectional lead screw 483 is rotatably connected to the side wall of the guide rod 482. The bidirectional lead screw 483 is connected to a drive motor. The drive motor drives the bidirectional lead screw 483 to rotate. When the bidirectional lead screw 483 rotates, it can also drive two sets of connecting plates 484 to move. The drive motor is connected to the side wall of the guide rod 482. Please see Figure 5 - Figure 7 The double-acting lead screw 483 is internally threaded to the connecting plate 484, and the connecting plate 484 is slidably connected to the guide rod 482, providing a limiting force for the movement of the connecting plate 484 and facilitating the movement of the connecting plate 484. Please see Figure 5 - Figure 7 The bottom of the connecting plate 484 is fixedly connected to the blade body 485. An insulating layer is provided at the connection between the connecting plate 484 and the blade body 485. The connecting plate 484 can move along with the blade body 485 while moving. The recessed space inside the blade body 485 is provided with an insulating layer and a heat insulation layer, which can effectively prevent the unexpected diffusion of current or heat damage to the collected sample during the cutting process. Specifically, there are two sets of connecting plate 484 and blade body 485. The blade body 485 is concave. The side walls of the two sets of blade bodies 485 that are close to each other are provided with sharp ends 488. The sharp ends 488 at both ends are close to each other and can cut the tissue and preserve it inside the blade body 485. Please see Figure 5 - Figure 7 The blade body 485 has a hollowed-out channel 4861, which is connected to the suction hole 486. The suction hole 486 is located on the side wall of the blade body 485. Please see Figure 5 - Figure 7 The other end of the channel 4861 is connected to the conveying pipe 487. The other end of the conveying pipe 487 passes through the contact ring 481 and communicates with the inner channel of the connecting rod 47. The inner channel of the connecting rod 47 is connected to the connecting pipe 5. Specifically, when using the device, medical staff connect the connector 2 to the outside world. The medical staff hold the operating unit 1 and move the blade 485 to the operating end area. When it is necessary to sample the operating area, the medical staff controls the drive motor to drive the bidirectional lead screw 483 to rotate. The bidirectional lead screw 483 drives the blades 485 to move away from each other through the connecting plate 484. Then, the tissue to be taken is placed in the space between the two sets of blades 485. Then, the bidirectional lead screw 483 drives the blades 485 to move closer to each other through the connecting plate 484. The sharp ends 488 on the two sets of blades 485 squeeze and cut the tissue, and collect the tissue inside the blade 485 for storage. Then, during use, the blade body 485 is powered on to treat the tissue area; After use, the electromagnetic spring drives the upper ring 431 to move downward, and the upper ring 431 drives the inner cylinder 43 to move downward. When the upper ring 431 moves downward, it squeezes the lower delivery bag 433. The air in the delivery bag 433 is delivered to the inside of the contact bag 434. During the downward movement of the inner cylinder 43, the contact bag 434 expands and contacts the surface of the blade 485. The inner cylinder 43 wraps the blade 485 inside. When the contact between the contact bag 434 and the blade 485 disappears, the contact bag 434 wraps the bottom area of ​​the inner cylinder 43 inside, so that the blade 485 is wrapped and sealed between the inner cylinder 43 and the outer cylinder 41. Secondly, the motor 45 can be controlled to drive the active gear 44 to rotate, the active gear 44 drives the driven gear 46 to rotate, the driven gear 46 drives the outer cylinder 41 to rotate as a whole, and the outer cylinder 41 can also drive the ultrasonic probe 42 to rotate and adjust its position; while the outer cylinder 41 rotates, it also drives the contact bladder 434 inside to rotate. When the contact bladder 434 rotates, the rough structure of its inner surface rubs against the surface of the blade 485, and facilitates the friction of impurities on the surface of the blade 485. The inner cylinder 43 is controlled by an electromagnetic spring to move and adjust the contact position between the contact bladder 434 and the blade 485.
