Cleaning balls for pipe-type medical devices and manufacturing method thereof

The present invention relates to a cleaning ball for a coronary medical device and a method for manufacturing the same, and more specifically, to clean the coronary medical device used in a minimally invasive surgery without using a separate brush or the like, and injecting the coronary medical device with a cleaning solution. It relates to a cleaning ball for a tubular medical device configured to be cleaned and a method for manufacturing the same.

In general, minimally invasive surgery is a surgical technique that minimizes incision by inserting a surgical tool into the body of a patient (or an animal to be operated on) and performing surgery through at least one small incision.

The most common form of minimally invasive surgery is endoscopic surgery, and the most common form of surgery is laparoscopic surgery that involves minimally invasive investigation and surgery in the abdominal cavity.

In the case of standard laparoscopic surgery, the gas is filled into the patient's abdomen, and at least one small incision is made to provide an entrance to a laparoscopic surgical tool, and then a trocar is inserted to perform the surgery. Is done.

When performing such surgery, it is common for a user to send a laparoscopic surgical tool through a trocar to a surgical site and manipulate (or manipulate) it outside the abdominal cavity.

On the other hand, the endoscope is usually developed to be inserted into the patient's body through a resection of the patient's mouth, anus or abdomen, etc., to observe the condition of the desired affected area with the naked eye. It is a medical device that plays a very important role.

As such, it is preferable to prevent secondary infections that may occur during reuse by using the endoscopic device used to be inserted into an organ of the human body, a catheter inserted into blood, a trocar, etc., instead of being reused as much as possible. Do.

However, most of these tubular medical devices are expensive devices that are reused by cleaning and disinfecting rather than using and disposing of them once if necessary, such as a hospital environment.

On the other hand, it is true that the exterior of the tubular medical device is easily cleaned to remove impurities and reused through normal washing, but the interior of the tubular medical device is not easy to clean.

Accordingly, a method for effectively sterilizing and cleaning pathogens while being harmless to the human body in order to use such a medical device for examination of other patients (Patent Document 0001) and Korean Utility Model No. 20-2016-0000822 (Patent Document 0002) Korea It has been steadily sought as suggested in published patent publication No. 10-2013-0000043.

As an example, as a conventional technique for cleaning (disinfection) of such a coronary medical device, a method of sterilizing the coronary medical device with hot steam, steaming ethylene oxide gas, or performing heat drying or ultrasonic cleaning was performed.

In addition, a method of cleaning using a brush or the like that can be inserted into the tube was used to remove residual substances attached to the inside of the tube medical device.

However, such a conventional cleaning method has a problem in that it is difficult to use when the medical device is sensitive to heat, and chemical agents can adversely affect the human body and not obtain a sufficient cleaning effect.

In addition, the cleaning of a conventional tubular medical device using a brush may generate a blind spot where the brush does not reach depending on the position and shape of the brush inserted into the tube, and even if it is supplemented by spraying a cleaning solution or the like, a sufficient cleaning effect cannot be obtained. There was a problem.

On the other hand, in order to solve such a conventional problem, a method for cleaning a tubular medical device has been proposed by introducing a large number of washing balls having a size of several mm to several centimeters together with a cleaning solution such as water inside the tubular medical device.

1 (a) and 1 (b), the cleaning ball 12 is injected with the cleaning liquid 11 into the interior of the coronary medical device 10 requiring cleaning, and the cleaning ball 12 is During injection (A) and discharge (B), the residual material 13 on the inner wall is scraped off.

The cleaning ball 12 has a surface roughness, and the cleaning of the coronary medical device 10 using the cleaning ball 12 can remove the residual material 13 inside the medical device 10 easily and reliably without blind spots compared to the prior art. Could.

However, the cleaning ball 12 is made by winding the fiber, that is, the yarn on the failure 12a constituting the conventional skeleton while applying a strong pressure, and there is a problem in that the production of the product is very difficult.

In addition, it was difficult to manufacture the cleaning ball 12, and mass production was difficult at one time. Even if the simple fibers with the failed 12a were agglomerated to form a thread bundle, the manufacturing was not easy, resulting in many problems.

Therefore, there is a limitation in the use of the cleaning ball 12, and there is a need for a cleaning ball 12 that solves this problem and is easy to mass-produce and does not use a conventional brush or the like and has excellent efficiency.
