Problems solved by technology

If the existing optical fiber control device is used, after the optical fiber is retracted, it is necessary to use the sheath of the observation mirror to push and strip the tissue to complete the blunt dissection of the tissue. However, it will be difficult to control the depth of blunt dissection. It is not easy to master the strength of blunt dissection, which increases the difficulty of the operation, especially the learning curve for beginners

Abstract

The invention provides a prostate laser enucleation device which is applicable to the prostate tissue in the urinary bladder. The prostate laser enucleation device comprises a lens sheath body and an enucleation lever outer sheath, wherein an observation mirror is arranged in the lens sheath body; the enucleation lever outer sheath is arranged at the bottom of the lens sheath body and connected with the lens sheath body; an enucleation lever and an optical fiber channel are arranged in the enucleation lever outer sheath; the enucleation lever is arranged at the bottom of the optical fiber channel; an optical fiber is arranged in the optical fiber channel and used for performing laser cutting of a tissue; an enucleation head is arranged at one end of the enucleation lever; the enucleation head protrudes out of the enucleation lever outer sheath; and with a shovel shape, the enucleation head is used for performing blunt dissection of the tissue. In the invention, the optical fiber can be stably controlled, and an enucleation head for blunt dissection can be provided so as to finish the cutting and blunt dissection of the tissue and carry out the operation more smoothly.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a prostate laser enucleation and pushing device, which is suitable for the prostate laser enucleation operation of the urinary system. Background technique [0002] Benign prostatic hyperplasia (BPH) is the most common chronic progressive urinary system disease among middle-aged and elderly men. Lead to serious complications, and even cause systemic diseases. Several surveys have shown that the prevalence of BPH is more than 43% in 60-year-old men, and more than 80% in 80-year-old men, and more than 1 / 3 of the patients need surgical treatment to relieve clinical symptoms. With the widespread application of minimally invasive transurethral surgery in clinical work, prostatic enucleation has gradually replaced open surgery and has become the "gold standard" in the treatment of BPH. Among them, Holmium Laser Enucleation of the Prostate (HoLEP for short) has become the main...
