Description
Technical Field
The utility model relates to the technical field of medical appliances, in particular to a tissue flusher for transurethral electrotomy.
Background
Along with the development of minimally invasive endoscopic techniques, transurethral electrotomy (including transurethral bladder tumor electrotomy and transurethral prostate electrotomy) has become a main treatment means for various diseases such as urinary bladder tumor, prostatic hyperplasia and the like. Transurethral electrotomy is a minimally invasive procedure that uses a specialized endoscope to extend into the bladder through the natural urethra, and then uses special electrotomes to resect the bladder tumor or the hyperplastic tissue of the prostate. After the transurethral bladder tumor electroincision or (and) the prostate electroincision operation is finished, a plurality of bladder tumor or prostatic hyperplasia tissue fragments remain in the bladder, so that the tissue specimens are conveniently collected, and the urinary tract is also prevented from being blocked by the tissue fragments, and the tissue fragments are required to be discharged out of the body through bladder irrigation.
Currently, ai Like or huffman irrigators are routinely used clinically to irrigate and collect tissue fragments within a patient's bladder. The device is generally composed of a flushing pipe connecting the endoscope and the flushing bottle, which is of a soft material and contains a liquid. Medical staff repeatedly squeezes the bottle body to flush the water in the bottle into the bladder, and tissue fragments can enter the flushing bottle along with water flow during back suction, so that the tissue fragments in the bladder are recovered. However, the device still has some disadvantages: (1) the device does not have any valve or filter screen, so that a small amount of tissue fragments can be re-extruded and flow back into the bladder, reducing the flushing efficiency, possibly resulting in insufficient flushing and possibly even causing tissue fragments to become stuck in the urethra or cystoscope sheath. (2) After the device (Ai Like or Huffman flusher) is used for flushing, an operator still needs to self-control a filter screen to filter liquid in the bottle so as to collect the tissue specimen for further pathological detection and diagnosis. The above processes are easy to cause pollution, time-consuming and labor-consuming, and can not distinguish different types of tissue specimens, and can influence pathological examination and even disease diagnosis.
Disclosure of Invention

The electric cutting mirror sheath connector can be connected with the end opening of the electric cutting mirror sheath, so that when the washing bottle is used for washing, washing liquid is prevented from leaking randomly, and clothes of operators and operators are prevented from being polluted; meanwhile, the liquid in the flushing bottle can be reserved to the greatest extent, enough impulsive force is generated when the flushing bottle is extruded and flushed, the flushing efficiency is improved as much as possible, and tissue fragments are collected.
Preferably, the diameter of the through hole is 2mm. This dimension ensures that water flows through the through hole into and out of the second irrigation conduit while blocking tissue debris from escaping out of the second irrigation conduit.
Preferably, the pore diameter of the filter screen is 2mm. This size allows for circulation of the water stream while avoiding leakage of the tissue sample into the wash bottle.
Preferably, the rinse bottle is made of transparent material, thereby facilitating the operator to observe the conditions in the rinse bottle and in the collection bottle in real time.
