Description

Technical Field

[0001] The present invention relates to the field of ablation and rotational cutting devices, and specifically to a vacuum-assisted integrated ablation and rotational cutting device. Background Art

[0002] A breast lesion rotational cutting device is used for breast nodule surgery, which is a surgical device for rotational cutting of nodules in minimally invasive internal medicine surgery. It usually consists of a system host, a handle, a foot switch, and a rotational cutting needle. Among them, an external power supply powers the system host, and the operation mode can be set through the LCD touch screen of the system host. It provides power for the handle and monitors its output in real time. The handle is a component held by the operator and can clamp the rotational cutting needle, control the switches of the rotational cutting system and the negative pressure system to achieve the surgical purpose. The handle contains a cable for electrical connection between the host and the handle, and the host controls the motor inside the handle through signals to drive the rotational cutting needle to move in a specific manner. The foot switch includes a pedal and can control the switches of the rotational cutting system and the negative pressure system. The rotational cutting needle consists of an outer cutter head part with a blade tip and a window and an inner cutter head part with a blade. During the cutting process, the inner cutter head of the rotational cutting needle rotates and cuts, sucks the nodule tissue into the window of the outer cutter head through negative pressure, uses the shear force generated between the inner cutter head and the window of the outer cutter head to cut the tissue, and sucks out the tissue through a vacuum pump. Its most common complication is local hematoma.

[0003] An ablation device is used for liver solid tumor and thyroid nodule surgery. It is a surgical device for ablation of solid tumors or nodules in minimally invasive internal medicine surgery. It usually consists of a system host, an ablation electrode, a neutral electrode, a peristaltic pump, a cooling water pipe, and a foot switch. Among them, an external power supply powers the system host, and the operation mode can be set through the knobs and buttons of the system host. It provides energy for the ablation electrode and monitors its output in real time. The ablation electrode is a component held by the operator to achieve the surgical purpose. The ablation electrode contains a cable for electrical connection between the host and the ablation electrode, and the host transmits energy through the cable. The neutral electrode is a component that contacts the patient and forms a current loop with the ablation electrode. The neutral electrode contains a cable for electrical connection between the host and the neutral electrode and transmits the current of the ablation electrode back to the host. The peristaltic pump is a component that drives the cooling water and is installed on the host. The cooling water pipe is a component that carries the cooling water. One part is installed on the peristaltic pump and is connected to the water tank and the ablation electrode to cool the ablation electrode through the drive of the peristaltic pump. The foot switch includes two pedals that can respectively control the on / off of the ablation electrode.

[0004] Currently used ablation devices are not easy to completely ablate and inactivate medium-sized liver solid tumors. There is an easy aggregation of coagulative necrosis substances, high ablation energy, occurrence of related severe complications, and risks of liver bleeding and rupture. To completely ablate medium-sized HCC, it is likely to cause local ischemic injury to the liver and secondary fatal acute liver failure. The aggregation of a large amount of coagulative necrosis tissue and the release of cytokines trigger hypotension and inflammation, inducing acute kidney injury and causing the deposition of uric acid, xanthine, and calcium phosphate crystals in the kidneys. At the same time, long-term and large-scale ablation increases the risk of hemoglobin and myoglobin released into the blood and blocking the renal tubules, which will further exacerbate acute kidney injury and secondary fatal tumor lysis syndrome. And the duration of tumor ablation syndrome is even longer. Summary of the Invention

[0047] Regarding the surgical procedures, according to the surgical needs of doctors and patients, surgical procedure one can be ablation first and then rotary cutting, surgical procedure two can be rotary cutting first and then ablation, or surgical procedure three can be cyclic ablation and rotary cutting for larger lesions;

[0048] Surgical procedure one:

[0049] Under image guidance, select a safe puncture path and puncture the coaxial needle 500 into the liver lesion or thyroid lesion; place the radiofrequency ablation needle 400 into the lesion along the coaxial needle 500. At the same time, inject an appropriate amount of 0.9% normal saline through the negative pressure module 600 along the coaxial needle 500 to increase the conductivity. Obtain a stable coagulation necrosis area through radiofrequency ablation, and then withdraw the radiofrequency ablation needle 400; place the rotary cutter head 300 along the coaxial needle 500 to rotary cut and grind the coagulation necrosis tissue. Inject an appropriate amount of 0.9% normal saline through the negative pressure module 600 along the coaxial needle 500 to soften the coagulation necrosis tissue and dilute the debris of the necrotic tissue. Aspirate the debris of the necrotic tissue through the negative pressure module 600, and then pull out the coaxial needle 500.

[0050] Surgical procedure two:

[0051] Under image guidance, select a safe puncture path and puncture the coaxial needle 500 into the liver lesion or thyroid lesion; place the rotary cutter 300 along the coaxial needle 500 to rotary cut and grind the coagulation necrosis tissue. Inject an appropriate amount of 0.9% normal saline through the negative pressure module 600 along the coaxial needle 500, and aspirate the tissue debris through the negative pressure module 600. Place the radiofrequency ablation needle 400 into the lesion along the coaxial needle 500. At the same time, inject an appropriate amount of 0.9% normal saline through the negative pressure module 600 along the coaxial needle 500 to increase the conductivity. Perform electrocoagulation hemostasis through radiofrequency ablation, and then withdraw the radiofrequency ablation needle 400 and the coaxial needle 500, and electrocoagulate the puncture needle track.

[0052] Surgical procedure three:

[0053] Under image guidance, select a safe puncture path and puncture the coaxial needle 500 into the liver lesion or thyroid lesion; if a histological specimen is needed, place the rotary cutter along the coaxial needle 500 for appropriate rotary cutting and aspiration, and then withdraw the rotary cutter; place the radiofrequency ablation needle 400 into the lesion along the coaxial needle 500 for electrocoagulation hemostasis and coagulation of the lesion. At the same time, inject an appropriate amount of 0.9% normal saline through the negative pressure module 600 along the coaxial needle 500 to increase the conductivity. Obtain a stable coagulation necrosis area through radiofrequency ablation, and then withdraw the radiofrequency ablation needle; place the rotary cutter 300 along the coaxial needle 500 to rotary cut and grind the coagulation necrosis tissue. Inject an appropriate amount of 0.9% normal saline through the negative pressure module 600 along the coaxial needle 500 to soften the coagulation necrosis tissue and dilute the debris of the necrotic tissue. Aspirate the debris of the necrotic tissue through the negative pressure module 600, and then pull out the coaxial needle 500. Repeat the ablation step and the rotary cutting step in sequence until the lesion is completely inactivated; repeat the ablation step again to obtain a stable coagulation necrosis area, activate the electrocoagulation function, and at the same time withdraw the coaxial needle 500 and the radiofrequency ablation needle 400, and electrocoagulate the puncture needle tract to prevent bleeding and needle tract seeding.

[0054] During the rotary cutting step, when the handle button or the foot switch is pressed, the drive motor inside the handle operates according to the set working mode and rotational speed, driving the inner cutter head to rotate at high speed to cut tissue. As the cutting torque increases, the motor output torque increases. When the load torque exceeds 1.6 times the rated torque of the motor, the overload protection will be triggered and the motor will stop rotating to avoid burning out the motor. After restarting, it resumes operation.

[0055] During the ablation step, after starting on the main unit touch screen 101, the temperature data is transmitted via the temperature sensor 408 identified on the radiofrequency ablation needle and is displayed in real time on the touch screen 101 for monitoring. The high-precision impedance control algorithm can accurately control the ablation area and temperature. When the ablation temperature exceeds the set threshold, the device pops up a warning message and cuts off the output. It is possible to select to restart and resume operation.

[0056] As described above, it is only the specific implementation manner of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present disclosure can easily think of changes or substitutions, which should all be covered within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
