Description

A tissue compression device

technical field

The embodiment of the utility model relates to the technical field of medical devices, in particular to a tissue compression device.

Background technique

Male voiding dysfunction such as urinary leakage or even urinary incontinence caused by degenerative diseases of tissues and organs, pelvic floor trauma, and surgical complications is a major chronic disease that plagues many patients. At present, one of the main clinical methods for treating male urinary incontinence is to implant a series of kits in male patients, including structures such as urethral restraint devices, fluid storage bags, mechanical switches, and fluid connection tubes. Due to the structure of this type of implant It is complicated, the surgical trauma is large, the postoperative recovery time is long, and the switch needs to be pressed manually. On the one hand, tissue fibrosis will eventually form on the surface of the reservoir, which will reduce the performance of the reservoir and reduce the effect of imaging prosthesis.

Another serious disadvantage is that elements compressing, pinching or confining the body organ may injure the tissue wall of the urethra. In this way, the compressive action of the element on the organ results in the possible invasion of the element over time into the organ, possibly even penetrating the compressed part of the organ wall. Furthermore, the blood circulation in the compressed organ tissue wall portion is eventually blocked due to the pressure exerted by the element, thus resulting in poor blood circulation or blood circulation stop leading to deterioration of the compressed tissue.

Based on the above factors, there is no ideal treatment device for male leakage of urine or urinary incontinence.
