Description
Technical Field
The invention relates to the field of medical equipment, in particular to a frostbite prevention device for a rectal cancer cryoablation.
Background
Along with improvement of life quality and change of eating habits, incidence rate of colorectal cancer patients in China is in an increasing trend year by year, laparoscopic treatment is often adopted for the colorectal cancer patients, but for patients who are unwilling to remove anus or can not remove anus due to advanced age or self refusal of patients with serious basic diseases, advanced colorectal cancer and the like, low-level rectal cancer cryoablation is the most effective treatment method, and the colorectal cancer cryoablation adopts a freezing head at-180 ℃ to directly contact tumor bodies so as to dehydrate and rupture cancer cells or destroy tumor small blood vessels, lead to hypoxia, lead to death of the cancer cells and achieve the aim of apoptosis of the tumor cells, but in the process of freezing the tumor bodies by the freezing head, tissues beside the tumor bodies are possibly contacted to cause frostbite, and health of the patients is hurt by the low-level rectal cancer cryoablation, so that whether a device can prevent surrounding tissues from frostbite in the freezing process is not disclosed so far.
Disclosure of Invention
Aiming at the situation, in order to overcome the defects of the prior art, the invention aims to provide the frostbite prevention device for the rectal cancer cryoablation, which can effectively solve the problem that the rectal cancer cryoablation is easy to frostbite.
In order to achieve the aim, the technical scheme of the invention is that the freeze injury prevention device for the rectal cancer cryoablation comprises an anal dilator and an adjusting plate, wherein the anal dilator is a hollow circular body, scales which are uniformly distributed are arranged on the outer side surface of the anal dilator, the upper part of the anal dilator is an arc surface, an outwards horn-shaped convex edge is arranged on the periphery of a lower bottom opening, a freezing opening is formed in the side surface of the circular body of the anal dilator along the length direction, an arc adjusting plate and a handheld device which extend into the anal dilator are arranged on the opening at the lower part of the anal dilator, the upper part of the arc adjusting plate extends into the freezing opening and is matched with the freezing opening, fixing holes which are uniformly distributed are formed in the adjusting plate, the handheld plate is an arc plate, the radian of the handheld plate and the radian of the adjusting plate are the same as the radian of the freezing opening, 2 outwards convex fixing heads are arranged on the end part of the handheld plate which is close to the opening at the lower part of the anal dilator, and the fixing heads are inserted into the fixing holes on the adjusting plate to be clamped and fixed.
The invention has simple structure, novel and unique design, simple operation, less pain in treatment, no frostbite of tumor peripheral tissues in the freezing process and good social and economic benefits.
