Background

Laparoscopic surgery has become the most popular diagnosis and treatment mode for doctors and patients at home and abroad because of the remarkable advantages of small wound, quick recovery, exact effect and the like. The laparoscopic treatment mode through the natural cavity is developed based on the traditional endoscopic surgery, the minimally invasive surgery is further developed into a non-scar surgery, and the surface of a patient subjected to the surgery does not leave any scar, so that the surgery is also called as a non-scar surgery, no postoperative pain usually occurs, and the surgical method is an extremely good expression of the minimally invasive surgery. The laparoscopic surgery is a single-cavity laparoscopic surgery in essence. At present, although a foreign trans-anus endoscope operation system exists, due to the fact that the operation channels are expensive, no any movable space exists in the complete rigid design, the chopstick effect is quite obvious, the operation difficulty is remarkably increased, only a small number of surgeons with quite skillful endoscope operation can finish the operation, most surgeons are difficult to get up, and therefore popularization is difficult. Although the operation can be performed by using a common endoscope single-hole operation channel at some time, the operation is not popular due to the non-specialized design, difficult fixation, limited space exposure, high operation difficulty and the like, and the development and the use of the technology with good development prospect are greatly limited.

In this embodiment, the one-way flaps 14 prevent leakage of gases after the corresponding surgical instrument and endoscope pass through the corresponding holes.

When the rectal tumor is used, for example, a patient with fecal blood is clinically found to have the rectal tumor, the tumor is larger, the mucosa is rough and is accompanied by mild erosion, pathological biopsy and magnetic resonance or endoscopic ultrasound show that the tumor is tubular adenoma and is accompanied by high-grade intraepithelial neoplasia, and timely excision treatment is needed to prevent the tumor from further progressing, and the malignant tumor becomes rectal cancer. Because the tumor is larger, the digestive endoscopy excision is more difficult, and serious complications such as bleeding, perforation and the like are easily caused; the traditional laparoscopic surgery through the abdomen is selected, on one hand, the operation is more traumatic and has more serious complications, and on the other hand, the operation is difficult to locate and has higher cost. Therefore, the rectal tumor is most suitable to be excised under the anus endoscope, the wound is small, and the recovery is quick. However, the operation requires an anal endoscope system, and most hospitals do not have the system, so that even if the system is available, most doctors have great operation difficulty, the operation is time-consuming and labor-consuming, and the operation cannot be unwilling to actively develop. The utility model can obviously improve the acquisition rate of the operation technology, and can be well developed by a doctor as long as the doctor has a common laparoscope and can be skillfully applied to laparoscopic instruments. The specific operation is as follows: first, the preoperative routine perfects all preoperative inspection, eliminates surgical contraindications and cleans the intestinal tract. The operation adopts epidural or lumbar-hard combined anesthesia, and a patient takes a lithotomy position or a prone position and generally places a tumor in the lowest six-point direction for convenient operation. The conventional operation area is disinfected, a sterile towel is paved, anus is disinfected and dilated, all components are lubricated by paraffin oil, then the inner sleeve 1 is stretched into the outer sleeve 2, the outer sleeve 2 and the inner sleeve 1 are combined and then placed into an anal canal, and a suture is fixed on the periphery of the anus through a suture through a fixing hole 915. After the annular limiting piece 8 is clung to the periphery of the anus, the inner sleeve 1 can be taken out. The elastic end cap 3 and the external cavity fixing portion 202 of the outer sleeve 2 are assembled together after being screwed together. The vent pipe 6 on the elastic end cover 3 is connected with a carbon dioxide gas source, and then the vent valve 13 is used for connecting the vent pipe 6 and then inflating to establish a rectum operation space. The observation hole 4 is used for inserting a laparoscopic camera for observation, and two operation holes 5 are adopted, so that the two operation holes 5 are used for placing endoscopic operation instruments (separation forceps, ultrasonic knife, electric hook, needle holder and the like). At this time, a corresponding operation can be performed. Because the elastic end cover 3 has certain elasticity, and a plurality of clumsy and bloated TROCARs (puncture outfits) are prevented from being placed in the narrow space, the chopsticks effect is greatly lightened, and the operation is easy. After the tumor is completely resected, the screw cap can be unscrewed to take out the specimen, which is beneficial to the operations of hemostasis, flushing, suturing and the like. The smoke exhaust pipeline 7 is used for exhausting smoke generated in the operation process, so that the problem of shielding the view of the endoscope is avoided.

In summary, embodiments of the present utility model provide a laparoscopic single port trans-natural orifice operating channel device, comprising an inner cannula 1, an outer cannula 2 and an elastic end cap 3. The inner sleeve 1 is used for driving the outer sleeve 2 to extend into the anorectal environment and the like, and can play a role in guiding. The above-mentioned outer sleeve 2 is a main component for guiding surgical instruments, endoscopes and the like into the environment of the anorectal and the like, while being able to separate these components from the anorectal wall for facilitating the surgical operation. The elastic end cover 3 can play a role in supporting surgical instruments and endoscopes, and meanwhile, a plurality of clumsy and bulky TROCARs (puncture outfits) can be greatly prevented from being placed in a narrow space, so that chopsticks effect is greatly reduced, and the operation is easy. The outer sleeve 2 includes a cavity portion 201 and an outer cavity fixing portion 202, which are sequentially connected, the elastic end cap 3 is covered at one end of the outer cavity fixing portion 202 and is threadably connected to the outer cavity fixing portion 202, the elastic end cap 3 is provided with an observation hole 4 and a plurality of operation holes 5, and the observation hole 4 and the plurality of operation holes 5 are all communicated with the outer cavity fixing portion 202.
