Problems solved by technology

However, the above-mentioned operation process is difficult, takes a long time, and has many disadvantages, resulting in a relatively low efficiency of the operation; for example, when some simple air-filled channel devices inject gas into the cavity, the gas supports the elastic thin wall , the elastic thin wall stretches to form a regular channel, but the supported channel will inevitably collapse and sag, so the rectum cannot be completely stretched, and the removal of the tumor is complicated, which increases the difficulty of the operation for medical staff

Embodiment 1

[0038] The present invention will be further described below in conjunction with the accompanying drawings.

[0039] Such as Figures 1 to 9 A gas-filled channel device for taking out tumor specimens through the anus after colorectal surgery is shown, including several channel tubes 1, inflatable tubes 2, at least two support frames 3 and at least one diaphragm 4, and the channel tube 1 includes a head a , the middle part b and the tail part c, the wall surface of the passage pipe 1 is elastic thin wall, and the elastic thin wall encloses to form a cavity 5, and a vent capillary 10 is arranged between adjacent two passage pipes 1, and the passage formed by the enclosure There is a chamber in the middle of the tube 1, and an inner elastic sleeve 11 attached to the wall of the channel tube 1 is provided in the cavity, and an outer elastic sleeve 12 is provided on the outer surface of the channel tube 1 relative to the inner elastic sleeve 11 .

[0040] Such as Figure 1 to Fig...

Embodiment 2

[0050] Such as Figure 10 As shown, in this embodiment, on the basis of Embodiment 1, a support net 13 is provided on the inner wall of the channel tube 1 for stretching the channel tube 1 when inflated. The support net 13 includes several vertically and horizontally interlaced support ribs. The length of the distributed support ribs is consistent with the length of the channel pipe 1, and the laterally distributed support ribs are arranged along the circumferential direction of the channel pipe 1. The setting of the support net 13 can better open the channel pipe 1 to ensure that the support is opened. The shape of the channel tube 1 is optimal, and the support net 13 includes a number of vertically and horizontally evenly staggered support ribs. The existence of the support ribs ensures that each part of the channel tube 1 is supported by a uniform support surface when it is filled with gas. , the vertical difference is small, and the flatness is good, that is, the undulatio...

Embodiment 3

[0052] Such as Figure 11 and Figure 12 As shown, this embodiment is based on Embodiment 1 and Embodiment 2. The air-filled channel device can also include several channel tubes 1 and a layer of elastic sleeves, and the channel tubes 1 are arranged along the outer surface of the elastic sleeve; The channel tube 1 is in the shape of a semi-cylindrical with both ends closed. The air-filled channel device is facing the side of the medical staff, and each port of the channel tube 1 is connected with an inflatable tube 2. The air flow regulator 14, the inflatable tubes 2 are externally connected to the same inflatable device; the several channel tubes 1 enclosed and arranged on the outer surface of the elastic sleeve directly contact the inner wall of the rectum when inflated, and the expansion effect of the rectum is better , in addition, there will inevitably be serious contraction, rectal polyps, inflammation and injury in the inner wall of the rectum of the patient. If the in...

Abstract

The invention discloses an air-filled channel apparatus for removing tumor specimens from anus after colorectal surgery. The air-filled channel apparatus comprises a plurality of channel tubes, air tubes, at least two support frames and at least one diaphragm, outer sides of the adjacent channel tubes in sequence are attached and enclosed, and each channel tube is of a cylinder with two ends enclosed and comprises a head, a middle part and a tail part; the wall surface of each channel tube is of an elastic thin wall, and the air tube is located at the tail part of the channel tube and is communicated with the cavity of the channel tube; a ventilation tube is arranged between two neighboring channel tubes and is connected with the neighboring cavities, the diaphragms are arranged in the cavities of the channel tubes, the diaphragms are made of elastic materials, and edges of the diaphragms are tightly connected with the wall surfaces of the channel tubes. By the arrangement, the rumor removed from the anus is assured not to touch the inner wall of the abdominal cavity and tissue in the same, shedding of tumor cells and occurrence of infection can be avoided, wall surface of the bowel can be supported when the air-filled channel apparatus is put into the bowel, and difficulty in operation is greatly lowered.

Description

technical field [0001] The invention relates to a medical device for laparoscopic surgery, in particular to an air-filled channel device for taking out tumor specimens through the anus after colorectal surgery. Background technique [0002] With the popularity of minimally invasive concepts, the rapid development of minimally invasive technology, and the development of minimally invasive equipment, surgery is undergoing an important revolution, and minimally invasive surgery has undoubtedly become the main role in the current surgical stage. Trauma, pain, scars, and negative psychological implications have long been considered inevitable outcomes of surgery. In recent years, the emergence of natural orifice specimen extraction surgery (NOSES) has found a new direction for minimally invasive treatment. Epidemiological data in my country show that 60% of the incidence of colorectal cancer in China is in the rectum, especially in the lower rectum, and 15% of the patients are y...
