Description

Prostate tissue collection device

Technical Field

The utility model relates to a collecting device, in particular to a prostate tissue collecting device.

Background

Prostatic hyperplasia is a common disease for middle-aged and elderly male patients. Prostate hyperplasia can lead to nocturia and difficult urination of patients, and serious patients can suffer from urinary retention, repeated urinary system infection, double hydronephrosis and even renal failure, and serious harm to the health of patients. Currently, aiming at severe prostatic hyperplasia, the main treatment mode is transurethral holmium laser enucleation of the prostate. In the operation process, the whole tissue of the prostate which is enucleated by the laser is crushed to form small pieces of prostate tissue fragments. The clinician needs to collect and place prostate tissue fragments into a specimen bag for further pathological examination to ascertain benign and malignant properties.

The existing prostate tissue fragment collection process method specifically comprises the following steps: a disposable bowl (curved plate) is used, a layer of medical gauze is covered on the surface of the bowl, and a mixture of tissue fragments (solid) and flushing liquid (liquid) is poured onto the gauze. By utilizing the characteristic that the diameters of tissue fragments are larger than those of holes of the gauze, the solid is finally stored above the gauze, and the liquid flows below the gauze, so that the effect of solid-liquid separation is achieved.

The existing prostate tissue fragment collection process has the inconvenience. Firstly, the equipment can not be reused, and the consumable cost is high; the second, solid-liquid separation device is non-integrated, need the temporary assembly while using, the efficiency is lower; thirdly, the solid-liquid separation is not thorough, and the gauze is easy to mix with the tissue block after dipping in water; fourthly, tissue fragments are adhered to gauze, so that tissue loss omission is easy to cause; fifth, the gauze is softer in the process of pouring the tissue block into the specimen bag, so that the operation is inconvenient for one person, and the operation needs the assistance of another person.
