Description
Technical Field
The invention relates to a catheter, in particular to an early warning catheter for low-level rectal cancer operation.
Background
Rectal cancer refers to cancer from the dentate line to the junction of the rectocele, which is one of the most common malignant tumors of the digestive tract. Surgery is one of the most important methods for treating rectal cancer. In China, the medium-low rectal cancer accounts for seventy percent. For doctors, the difficulty of middle-low level operation, especially low-level operation for protecting anus, can be larger than that of high-level rectal cancer. If the anus is not protected, the focus of the rectum and the anus are excised together, and then the abdomen of the patient is fistulized to realize daily defecation. Although this approach can ablate tumors, there is a great psychological stress on the patient and many inconveniences in life.
Thus, for rectal cancer patients, if at the same time a radical cure effect can be ensured, the protection of the anus is undoubtedly an invading expectation. However, due to the narrow pelvis, the relationship between the rectum and the surrounding is complex, such as patients with obesity, men or larger tumors, the lower-level anorectal protection operation of the rectum cancer becomes more complex, and serious massive hemorrhage and other side injuries can be caused by a little careless approach. Recently, new and advanced operations such as TaTME can be performed on patients with middle and low rectal cancer with difficult pelvis, the TME operation with higher quality can be performed on the patients with middle and low rectal cancer, the distal cutting edge of the specimen is ensured, the operation wound is smaller, and complications are more. The male should be kept in mind against urinary tract injuries. Because of physiological urethral curvature in the male urethra, wedge-shaped angulation occurs at the urethral membrane (urethral horn) and at the free surface when the anterior rectal wall is free along the denovilli fascia, and tangential damage to the urethra is often caused if sharp electrical energy cuts are sustained.
Today, doctors can only operate with anatomical landmarks and surgical experience when performing rectal cancer, especially low-grade rectal cancer surgery. A reasonable early warning device is lacked in the operation process to early warn the operation process of doctors, so that the urethra is prevented from being damaged by energy machinery. Common energy mechanisms include single stage electric hooks, bipolar electrocoagulation, ultrasonic blades, and the like.
In view of the foregoing, there is a need for an alert catheter for low-level rectal cancer surgery that meets the needs of the surgery.
