Description

Air inflation type channel device for taking out tumor specimen through anus after colorectal operation
Technical Field
The invention relates to a laparoscopic surgery medical instrument, in particular to an inflatable channel device for taking out tumor specimens through anus after colorectal surgery.
Background
With the deep penetration of the minimally invasive concept and the rapid development of minimally invasive techniques, the development of minimally invasive devices is an important revolution in surgical operations, and minimally invasive operations have become the main role of the current surgical stage without disputes. Wounds, pain, scars, and adverse psychological implications have been considered as the necessary product of surgery. In recent years, the advent of natural transluminal specimen retrieval surgery (natural orifice specimen extraction surgery, NOSES) has found new directions for minimally invasive treatment. Epidemiological data in China show that 60% of colorectal cancers in China are seen in the rectum, especially in the lower rectum, 15% of patients are less than 30 years old, and BMI data of the patients in China are relatively smaller, so that the method is more technically feasible. Literature shows that colorectal cancer NOSE operation is technically feasible in the operation process, the safety is basically similar to that of the traditional laparoscopic operation, the concurrency is not obviously increased, the colorectal cancer NOSE operation has more attractive effect, and the patient acceptability is high.
However, the specific naming, development conditions and technical platform, indication and contraindication, technical requirements for aseptic operation and non-tumor operation, and prevention and treatment of complications and the like of the NOSES are still in the starting stage, and the unified consensus and standard are not achieved yet, and various surgical operation methods and standards exist in clinical work. The domestic Wang Xishan professor and Fu Chuangang professor have made preliminary exploration of this type of surgery, and also established the domestic first professional alliance for NOSES for colorectal cancer, and issued the expert consensus for colorectal tumor sampling via natural lumen tract (2017).
In the operation process, the surgical instrument for taking the sample through the anus does not have special equipment. At present, a device for taking a sample through anus without a fixed shape is provided. The more used each expert is: 1. a cavity mirror sleeve. The method comprises the steps of opening the opening of an isolation bag for isolation through a surgical forceps in an operation abdominal environment, clamping the resected tumor specimen to enable the resected tumor specimen to enter the isolation bag, then continuously wrapping the tumor specimen on the opening of the isolation bag, and finally clamping the opening to take out the isolation bag and the tumor specimen wrapped inside. 2. Incision protective sheath. The lower rectum is placed into the incision protective sleeve through the anus, and the specimen is directly pulled out. However, the operation process has the defects of large operation difficulty, long operation time and a plurality of defects, so that the operation efficiency is relatively low; for example, when some simple air-filled channel devices inject air into the cavity, the air supports an elastic thin wall, and the elastic thin wall forms a regular channel after being spread, but the spread channel is inevitably collapse and concave, so that rectum can not be completely spread, the tumor is taken out, and the operation difficulty of medical staff is increased.
Therefore, the further reasonable design and perfection are needed, so that the operation is convenient to take out from the anus after the tumor is resected, the falling off of tumor cells and the occurrence of infection can be avoided, and the situation that the tumor is completely isolated from the abdominal cavity when taken out by the anal sample taking device is ensured.
