Description

Technical Field

[0001] The 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 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 can damage the ovaries and affect the patient's fertility. The cyst may rupture during peeling, causing the cystic fluid to leak out and even tearing the wound at the peeling site, leading to bleeding. Summary of the invention

[0003] The purpose of the present invention is to provide a cyst treatment system in view of the above-mentioned defects in the prior art.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] A cyst treatment system includes a medical host, the medical host includes a host shell, and an air pump and a peristaltic pump arranged in the host shell.

[0006] The negative pressure port of the air pump is connected to the negative pressure joint arranged on the main body shell, the negative pressure joint is connected to the waste liquid collection bucket through the negative pressure pipeline, the waste liquid collection bucket is connected to one end of the suction pipe external pipe arranged on the handle shell, and the other end of the suction pipe external pipe is connected to the suction pipe arranged at the front end of the handle shell through the suction channel arranged inside the handle shell.

[0007] A peristaltic pump connector is provided on the main housing, and the peristaltic pump connector includes a peristaltic pump inlet and a peristaltic pump outlet. The infusion bag is connected to the input port of the peristaltic pump through the infusion tube and the peristaltic pump inlet in sequence, and the output port of the peristaltic pump is connected to one end of the perfusion tube control valve installed on the handle housing through the peristaltic pump outlet, the positive pressure pipeline, and the external pipe of the perfusion tube. The other end of the perfusion tube control valve is connected to the perfusion tube arranged at the front end of the handle housing through the perfusion channel arranged inside the handle housing.

[0008] A pressure sensor is arranged at the outlet of the peristaltic pump, and the pressure sensor is connected to an alarm arranged inside the housing of the main unit.

[0009] A driving motor for driving the spiral rod to rotate is arranged in the handle housing. The spiral rod is arranged in the suction tube. The driving motor is electrically connected to the spiral rod switch arranged on the main housing. The spiral rod switch is connected to the motor controller in the main housing through a cable and a corresponding plug on the coagulation and cutting joint on the main housing.

[0010] The rotating shaft of the driving motor is connected to the driving claw, the driving claw is buckled with the transmission claw, the transmission claw is connected to the adapter shaft, the adapter shaft is arranged in the suction channel through a bearing, and the adapter shaft is axially connected to the rear end of the spiral rod.

[0011] The bearing is a waterproof sealed bearing.

[0012] A sealing ring is also arranged between the portion of the adapter shaft located at the front end of the bearing and the suction channel.

[0013] The gap between the suction tube and the spiral rod is 0.1 mm-0.2 mm.

[0014] The perfusion tube and the suction tube are welded together, and the perfusion tube or the suction tube is electrically connected to the electrode switch arranged on the main housing.

[0016] The driving claw and the transmission claw are made of PC plastic.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention uses a medical host to provide positive pressure, and delivers the liquid medicine or saline in the infusion bag to the inside of the cyst through the perfusion tube; the medical host provides negative pressure, and sucks the viscous chocolate pus through the suction tube, which greatly reduces the burden of doctors during surgery.

[0019] 2. Traditional treatment requires laparotomy for complex, viscous and large chocolate cysts, but the present invention can be used under B-ultrasound and endoscopy, which is a minimally invasive surgery.

[0020] 3. The traditional treatment of chocolate cysts may cause defects such as cyst rupture, cyst fluid overflow, ovarian damage, and wound tearing during peeling. The present invention uses the method of perfusion and suction to extract the cyst fluid from the inside of the cyst out of the body, and cooperates with radiofrequency ablation electrodes to perform radiofrequency ablation treatment on the cyst, thereby avoiding the damage caused by peeling.

During the suction process, the spiral rod 312 is kept rotating, and the rotating spiral rod 312 and the inner wall of the suction tube 302 form a closed space. These spaces are similar to the principle of Archimedean screw pumps, and can also suck cystic fluid, and can also prevent cystic fluid from accumulating inside the suction tube 302 and blocking the suction tube 302. After the cystic fluid inside the cyst is sucked out, the cyst can be subjected to radiofrequency ablation treatment.
