Prostatic enucleation scope

Abstract

The invention provides a prostatic enucleation scope for carrying out blunt dissection and enucleation of prostatic tissue, comprising a viewer body and an enucleation rod juxtaposed from top to bottom; a fiber passage is arranged in the enucleation rod and may extend out of the insert end of the enucleation rod; an optical fiber is arranged in the fiber passage; the insert end of the enucleationrod is provided with an enucleation head that is of duckbill structure; the enucleation head is connected with a handle arranged at the non-insert end of the enucleation rod; the enucleation head canbe controlled to open or close via the handle. The prostatic enucleation scope also comprises a sheath that sleeves the viewer body and the enucleation rod; the middle of the sheath is provided with an instrument passage; the wall of the sheath is of double-layer structure; a gap is arranged in the wall of the sheath; the insert end of the sheath is provided with a plurality of holes. The prostatic enucleation scope herein can effectively prevent injury of a patient's urethral sphincter due to long-term compression, and can provide timely hemostasis during prostatic dissection for the patientso that surgical treatment is facilitated and surgical time is effectively shortened.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a prostate enucleating mirror. Background technique [0002] Sphincter refers to a ring-shaped muscle distributed in the walls of certain lumens in humans and animals, often particularly thickened. In humans, sphincters are found in the digestive tract and urinary system. The sphincter closes the lumen when it contracts and opens the lumen when it relaxes, and is usually in a contracted state. There is an internal urethral sphincter at the junction of the urethra and bladder, which can close the internal opening of the urethra to prevent urine leakage when contracted. The membranous part of the urethra (urogenital septum) has the urethral sphincter, which is composed of striated muscle and is controlled by consciousness. [0003] Transurethral resection of the prostate (TURP) is a safe, effective, and pain-relieving surgical method. It refers to the insertion of a resectoscop...

Problems solved by technology

[0006] However, in the existing implementation methods, during the operation process, the hyperplastic glandular tissue and the like are likely to affect the line of sight, and the field of view is very small during the push and peel, and the mirror must be withdrawn for observation after the push and peel, which prolongs the operation process

[0007] It can be seen from the above that the prostate resectoscope in the prior art will use the patient's ...
