Description
Technical Field
The utility model relates to the technical field of medical appliances, in particular to a tissue specimen collector for transurethral electrotomy.
Background
With the development of minimally invasive endoscopic techniques, transurethral electrotomy (including transurethral bladder tumor electrotomy and transurethral prostate electrotomy) has gradually become a main treatment means for various diseases such as urinary bladder tumor and prostatic hyperplasia. 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. In the transurethral bladder tumor electrotomy or (and) prostate electrotomy process, the resected tissue specimens need to be collected, so that on one hand, the blockage of the postoperative urethra caused by the resected tissue residues in the bladder of a patient is avoided, and on the other hand, the resected tissue can also be used as an important detection sample for subsequent pathological diagnosis.
In order to collect tissue specimens in the current clinical operation process, a collection filter screen is usually arranged at the outlet of the resectoscope. The transurethral electrotomy needs to be filled with liquid to fill the bladder, after the tissue specimen is resected, an operator can withdraw the electrotome, stay the electrotome sheath tube in the urethra, and the liquid in the bladder flows out along the sheath tube and flushes out the tissue specimen along the belt. Thus, the tissue specimen will be intercepted on the collection filter as the fluid in the bladder flows out, and the operator can pick up the desired sample on the filter. However, this approach has several drawbacks: 1. because the liquid in the bladder fills, the water pressure in the sheath tube of the resectoscope is larger when the resectoscope is withdrawn, the water flow direction is difficult to control, the operating gown of a surgeon is easy to splash and pollute, and occasionally, the condition that a tissue specimen is flushed out of a filter screen and is difficult to collect can also occur. 2. The operation is not convenient enough and the tissue specimen is easy to pollute, which affects the subsequent pathological analysis.
