Visual bladder blood clot removing instrument

Abstract

The invention relates to the field of medical instruments, in particular to a visible bladder blood clot removing instrument which comprises an obturator, a lens and a suction injector, a flushing outlet is formed in the left side of a flushing working channel, an objective lens is arranged above the flushing outlet, a suction connector is formed in the right side of the flushing working channel, and a camera connector is installed above a lens rod. The instrument has the advantages that the instrument has a visual function through the objective lens, the camera interface and the cold light source interface, the instrument has two modes and functions, a suction mode or a suction mode can be selected according to blood clot properties, and the suction mode is suitable for sparse blood clots with short blood clot forming time; the suction mode is suitable for large-area coagulated compact organic blood clots which are long in blood clot forming time, so that large equipment and large instruments are not needed in the operation process, the burden of itinerant nurses is not increased, fixing equipment and instruments in a ready-made operating room can be utilized, and the convenient, safe and efficient performance is achieved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a visible bladder blood clot removal device. Background technique [0002] Bladder clot packing is a very common emergency in urology. The common causes are urinary system trauma such as renal contusion, bladder contusion, postoperative bleeding such as transurethral resection of bladder tumor and resection of prostate, and bladder irritation. inflammation, after intravesical chemotherapy. The onset of bladder clot tamponade is acute, and the patient presents with dysuria, severe abdominal pain, obvious abdominal distension, and extreme pain. Conservative treatment is often required, such as inserting a three-lumen catheter for continuous bladder irrigation. If conservative treatment fails, emergency surgery is required. These blood clot tamponade patients who need surgical treatment often have a long onset time, large blood clot volume, and a large number of organized blood clots...

Problems solved by technology

When using Ellik, sealing the stuffed bladder will invisibly increase the pressure, causing the bladder to rupture. It is reported that there is a 2.2% risk of rupture. Therefore, after each flushing of blood clots, the gas and liquid in the bladder should be released before the next flushing

[0004] Clinically, blood clots in the bladder are removed by quickly and repeatedly pulling and inserting the obturator with the Ellik flushing ball. During the process of rapidly and repeatedly pulling and inserting the obturator, the irrigation fluid splashes around the surgical area. Endoscopic instruments cut blood clots into small strips and use Ellik flushing balls to suck them out, but the efficiency is very low

Yu Limin and others used endoscopic aspirator to remove bladder blood clots, bu
