Ear canal cyst extraction device

Abstract

The invention provides an ear canal cyst extraction device, which includes a handle, and an ear canal tube assembled on the handle. A needle is designed inside the ear canal tube. The needle is made of magnetic material, so that the front and rear ends of the needle produce magnetic poles. , the direction of the magnetic field inside the puncture needle is along the direction of the puncture needle; the ear canal tube runs through front and back, and the front end of the ear canal tube is wrapped with an electromagnetic coil, the electromagnetic coil is connected to the power supply through a circuit, and the handle is designed with a control circuit on and off switch, the rear part of the ear canal tube is connected to the negative pressure chamber through a metal hose, and a negative pressure device is connected to the negative pressure chamber. The device pushes the front end of the ear canal tube deep into the cyst part of the patient's ear canal through the handle, energizes the electromagnetic coil through the current control, punctures the cyst with the forward thrust of the puncture needle, and draws out the liquid in the cyst through the ear canal tube. The device is simple and convenient to use, and the operation wound is small.

Description

Technical field [0001] The invention belongs to the technical field of medical devices, in particular to an ear canal cyst extraction device. Background technique [0002] A cyst is a benign cystic mass that grows in a certain organ in the body, and its contents are liquid in nature. Cysts are common in various organs of the body. As the human hearing organ, the ear has a common ear canal. Because the environment in the ear canal is relatively humid, there are excrements such as earwax, which can easily cause blockage of the excretion of body fluids, and it is also a location where cysts frequently occur. When the polyps in the ear are severe, the patient's hearing may be affected. When the cyst is located in the long ear canal, it is not convenient to perform surgery. Therefore, when performing a cutting operation on a cyst in the ear, special ear forceps or ear scissors are required for the operation. Traditional ear forceps and ear scissors are usually designed with lon...

Problems solved by technology

When the polyps in the ear are severe, it may affect the patient's hearing. When the cyst is located in the long ear canal, it is not convenient to perform surgery

Therefore, when performing a cutting operation on a cyst in the ear, special ear forceps or ear scissors are required for surgery. Traditional ear forceps and ear scissors are usually designed with long and pointed ends, which can be easily inserted into the head. to the position of the cyst in the ear canal, and then the cyst is clipped. In actual use, due to the narrow space in the ear canal, the traditional ear scissors are difficult to operate and the force is difficult to control. Moreover, the position of the cyst in the ear canal is often close to the tympanic membrane. During the operation, the instrument is likely to touch the tympanic membrane, causing the rupture of the tympanic membrane, and the operation has a greater risk

Moreover, the traditional cyst surgery in the ear canal often uses the method of cutting, which has a large wound, and after the cyst is cut open, the liquid substance in the cyst is easy to leak out and pollute the ear canal
