Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices and relates to a cyst treatment system suitable for cyst treatment. Background Art

[0002] In traditional cyst surgery, the cystic fluid in the cyst needs to be extracted. The doctor uses a syringe to repeatedly aspirate the cystic fluid. When aspirating viscous cystic fluid, it is necessary to add physiological saline solution to dilute the cystic fluid before aspirating it again. This process is done manually by the doctor and is very physically demanding. For sticky and complex chocolate cysts, the cyst is peeled off during surgery, which will damage the ovaries and affect the patient's fertility. The cyst may rupture during peeling, causing the cystic fluid to leak out or even tearing the wound at the peeling site, leading to bleeding. Summary of the Invention

[0032] The accessory handle 3 includes a handle shell 308, and a suction channel 315 and a chamber are provided inside the handle shell 308. The suction channel 315 and the chamber are separated by a partition, and the partition is provided with an opening so that the suction channel 315 is connected to the chamber. An external pipe 306 for the perfusion tube is provided on the handle shell 308. One end of the external pipe 306 for the perfusion tube is connected to one end of the perfusion tube control valve 305 installed on the main body shell 201 through a Luer joint, and the other end of the perfusion tube control valve 305 is connected to one end of the perfusion channel provided inside the handle shell 308.

The transmission claw 311 is provided in the chamber inside the handle shell 308. The chamber inside the handle shell 308 is also provided with a driving claw 310 and a driving motor 309.

The driving motor 309 is electrically connected to the spiral rod switch 304 provided on the main body shell 201. The spiral rod switch 304 is connected to the motor controller in the main body shell 201 through a cable and a corresponding plug on the condensation connector 203 on the main body shell 201.

[0037] In this embodiment, the gap between the suction tube 302 and the spiral rod 312 is 0.1 mm-0.2 mm.

[0038] In some embodiments, a bearing 313 is further included. The inner ring of the bearing 313 is clamped on the adapter shaft 314, and the outer ring of the bearing 313 is clamped in the suction channel 315, so that the rotation of the transmission claw 311 is more stable.

[0039] Furthermore, a sealing ring is provided between the portion of the adapter shaft 314 located at the front end of the bearing 313 and the suction channel 315; the bearing 313 is a waterproof sealed bearing, and the setting of the sealing ring and the waterproof sealed bearing can prevent waste liquid from entering the chamber from the suction channel 315.

[0040] The perfusion tube 301 and the suction tube 302 are welded together. The perfusion tube 301 or the suction tube 302 is electrically connected to the electrode switch 303 provided on the main housing 201. The electrode switch 303 is connected to the positive pole of the radio frequency module in the main housing 201 through a cable and a corresponding insert on the coagulation connector 203 on the main housing 201. The negative pole of the radio frequency module is connected to the negative plate through a cable and a plate connector 211 on the main housing 201. The perfusion tube 301 and the suction tube 302 output radio frequency energy simultaneously.

[0041] In some embodiments, the material of the perfusion tube 301 and the suction tube 302 is stainless steel.

[0042] In this embodiment, the driving claw 310 and the transmission claw 311 are made of PC plastic (polycarbonate). PC plastic has insulating properties and can prevent radio frequency interference with the driving motor 309 .

[0043] During use, the main unit power switch 202 is pressed to activate the medical main unit 2, which is then powered on. Under ultrasound guidance or endoscopic manipulation, the infusion tube 301 and suction tube 302 of the accessory handle 3 are inserted into the chocolate cyst. The peristaltic pump is activated on the control panel 206. After being pressurized by the peristaltic pump, saline or liquid medicine flows from the infusion bag 1 through the positive pressure line 209 to the accessory handle 3, ultimately flowing from the infusion tube 301 of the accessory handle 3 into the cyst to dilute the chocolate cyst. At this point, the screw switch 304 is pressed to activate the drive motor 309, which rotates the screw 312 to whip the cystic fluid and dilute it with saline. The air pump is activated on the control panel 206, which provides negative pressure from the negative pressure connector 205, providing a negative pressure source for the accessory handle 3 via the waste liquid collection bucket 4. Finally, negative pressure is output from the suction tube 302, drawing the cystic fluid from the cyst into the waste liquid collection bucket 4 via the suction tube 302. During the suction process, the spiral rod 312 is kept rotating. The rotating spiral rod 312 and the inner wall of the suction tube 302 form a closed space. This space, similar to the principle of an Archimedean screw pump, also sucks cystic fluid and prevents cystic fluid from accumulating inside the suction tube 302 and clogging the suction tube 302. After the cystic fluid is completely sucked out, radiofrequency ablation treatment can be performed on the cyst. The negative electrode plate is attached to the patient and the electrode switch 303 is pressed. The medical host 2 will provide radiofrequency energy output to the accessory handle 3, providing radiofrequency ablation through the irrigation tube 301 and the suction tube 302 of the accessory handle 3, and performing radiofrequency ablation on the affected cyst area.

Persons skilled in the art may make various modifications, additions, or substitutions to the described embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
