Description
Technical Field
The invention relates to the field of medical instruments, in particular to a rectal cancer cryoablation anti-freezing injury device.
Background
With the improvement of life quality and the change of dietary habits, the morbidity of colorectal cancer patients in China is on the trend of increasing year by year, the colorectal cancer patients are usually treated by a laparoscope, but the treatment by using the low-position rectal tumor cryoablation is the most effective treatment method for patients who are unwilling to or unable to remove the anus because of old age or refusal to remove the anus, serious basic diseases, late rectal cancer and the like, the rectal cancer cryoablation adopts a freezing head at the temperature of-180 ℃ to directly contact with a tumor body, so that cancer cells are dehydrated and broken, or small blood vessels of the tumor are damaged, oxygen deficiency is caused, the cancer cells are killed, the purpose of apoptosis of the tumor cells is achieved, but in the process of freezing the tumor body by the freezing head, tissues beside the tumor body are likely to be contacted to cause frostbite, the health of the patients is damaged, and no device can prevent peripheral tissues from being frostbitten in the freezing process, so far, no public report is found.
Disclosure of Invention
In view of the above situation, in order to overcome the defects of the prior art, the present invention aims to provide a rectal cancer cryoablation frostbite prevention device, which can effectively solve the problem of easy frostbite during rectal cancer cryoablation.
In order to achieve the purpose, the technical scheme of the invention is that the rectal cancer cryoablation injury prevention device comprises an anus dilator and an adjusting plate, wherein the anus dilator is a hollow circular body, uniformly distributed scales are arranged on the outer side surface of the anus dilator, the upper part of the anus dilator is an arc surface, an outward horn-shaped convex edge is arranged on the periphery of an opening of the lower bottom, a freezing opening is formed in the side surface of the circular body of the anus dilator along the length direction, an arc-shaped adjusting plate and a hand holder which extend into the anus dilator are arranged from an opening at the lower part of the anus dilator, the upper part of the arc-shaped adjusting plate extends into the freezing opening and is matched with the freezing opening, uniformly distributed fixing holes are formed in the adjusting plate, the hand holder is an arc-shaped plate, the radian of the hand holder and the adjusting plate is the same as that of the freezing opening, 2 fixing heads which protrude outwards are arranged at the end part of the hand holder which is close to the opening at the.
The invention has simple structure, novel and unique design, simple operation, less pain in treatment, no frostbite on peripheral tissues of the tumor body in the freezing process and good social and economic benefits.
