Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically to an enterostomy intestinal blood supply monitoring device. Background Technology

[0002] An enterostomy is an artificial opening made in the abdominal wall by a surgeon to treat certain intestinal diseases such as rectal cancer and ulcerative colitis. A section of the intestine is pulled out of the opening, turned inside out, and sutured to the abdominal wall, thus forming an enterostomy. Its function is to replace the original perineum and anus for defecation; it is essentially a diversion of the fecal exit. After the enterostomy surgery is completed, the blood supply of the enterostomy section needs to be observed to prevent complications such as stoma ischemic necrosis.

[0003] Currently, the clinical method for observing the blood supply of intestinal segments within an enterostomy involves using a blank test tube with a flashlight placed above it as a light source. However, this method is ineffective for observing the blood supply to the lateral walls of the enterostomy, and it is also difficult to observe deeper areas of the intestine. Therefore, there is a need for an enterostomy blood supply observation device that can effectively observe the lateral walls of the enterostomy and also observe the blood supply to deeper areas of the intestine. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an enterostomy intestinal blood supply observer that can effectively observe the sidewall of the enterostomy intestinal tract and at the same time observe the blood supply of the intestinal tract in a relatively deep area.

Used to connect the second spur gear ring 27 and the meshing gear ring 33, one end of the second adjusting rod 30 is connected to the curved rod 29, and the other end extends outward through the side wall of the observation tube 1. The mounting ring 9 is provided with an adjusting groove 36 corresponding to the side wall of the observation tube 1. The second adjusting rod 30 slides in the adjusting groove 36. The adjustment function is achieved by the upper and lower misalignment of the first connecting gear ring 34 and the second connecting gear ring 35. At the same time, the second adjusting rod 30 extends outward through the side wall of the observation tube 1, which is convenient for the operator to operate.

[0033] Preferably, both the first adjusting rod 28 and the second adjusting rod 30 include a first rod 37, a second rod 38, and a third rod 39.

The arrangement of the plurality of lighting lamps 46 and the reflective baffle 47 can effectively enhance the lighting effect.

[0036] During observation of the enterostomy sidewall, the second adjusting rod 30 is moved along the adjusting groove 36 by turning it, thereby causing the second connecting gear ring 35 to mesh with the meshing gear ring 33 and the third spur gear ring 48 respectively. Further rotation of the third adjusting rod 31 causes the third bevel gear 32 to rotate, which in turn drives the first adjusting rod 28. The rotation further drives the meshing gear ring 33 to rotate, which in turn drives the second connecting gear ring 35 to rotate, the third spur gear ring 48 to rotate, the first spur gear ring 24 to rotate, and the transmission gear 23 to rotate. Through the connecting rod 22, the second bevel gear 21 to rotate, which in turn drives the first bevel gear 20 to rotate, thereby driving the rotating rod 18 to rotate. This causes the one-way mirror 11 to perform a horizontal flipping action. After the horizontal flipping is adjusted to a suitable angle, the second adjusting rod 30 is moved along the adjusting groove 36 by moving the second adjusting rod 30, thereby driving the first connecting gear ring 34 to mesh with the meshing gear ring 33 and the second spur gear ring 27 respectively. The third adjusting rod 31 is then rotated, driving the third bevel gear 32 to rotate, which in turn drives the first adjusting rod 28 to rotate, further driving the meshing gear ring 33 to rotate, and further driving the first connecting gear ring 34 to rotate, thereby driving the second spur gear ring 27 to rotate, which in turn drives the rotating ring 17 to rotate, thus realizing the circumferential rotation of the one-way mirror 11, thereby enabling complete observation of the enterostomy side.
