Stone filtering collector

Abstract

The invention discloses a stone filtering collector. The stone filtering collector comprises a cover and a main body, wherein the main body is provided with a cavity; the cover is provided with a connecting tube and communicates with an endoscopic sheath water outlet channel; a filtering device with a filter screen is arranged in the main body; the filtering device divides the cavity in the main body into a collecting cavity and a liquid draining cavity; the connecting tube communicates with the collecting cavity; and the liquid draining cavity is provided with a water draining tube. By the filtering collector which is connected with the endoscopic sheath water outlet channel, the purpose of filtering and separating mixed liquid is achieved while surgery is implemented, stone samples and soft tissue samples are directly extracted from the inside of the filtering device, work efficiency of medical workers is greatly improved, workload is reduced, the soft tissue samples can be effectively prevented from being lost, stone ingredient detection or soft tissue pathological examination can be finished effectively in time, and services can be provided for patients well subsequently.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a calculus filter collector. Background technique [0002] Clinically, minimally invasive intracavitary techniques have basically replaced traditional open surgery in the treatment of urinary calculi. Among them, the treatment of upper urinary tract stones through the natural channel of the human body has developed into a mainstream surgical method, and its safety, effectiveness and speed have been recognized by doctors and patients. During the operation, it is necessary to insert a soft sheath or a hard sheath through the natural passage of the human body such as the urethra, bladder, ureter, etc. to the surgical site to establish a passage, and then insert a flexible or hard ureteroscope through the passage, and use lithotripsy equipment such as holmium laser, etc. Lithotripsy is performed, and at the same time, irrigation fluid is continuously injected through the flexible ureteroscope...

Problems solved by technology

During this process, the excreted gravel, soft tissue and flushing fluid form a mixed solution, and medical staff often need to go through tedious and time-consuming steps such as filtration, sedimentation, and collection to separate the stones from the mixed solution, thereby extracting stone samples In order to complete the component detection and provide patients with follow-up targeted prevention and treatment plans; the above-mentioned cumbersome separation and extraction steps not only take too long, but also increase the workload of the original heavy medical staff; For patients who extract soft tissue for pathological examination, since the soft tissue is not easy to separate from the mixed liquid after it is discharged from the water outlet channel of the scope sheath together with the mixed liquid, it is easy to cause loss, and it also brings inconvenience to the work of medical staff
