Urethral probe with an adjustable circumference

Abstract

The invention relates to the field of medical instruments, in particular to a urethral probe with an adjustable circumference. The probe comprises a rod body and a handheld handle, the tail end of therod body is in threaded connection with the front end of the handheld handle, the rod body comprises a bending part and a linear part, the tail end of the bending part is communicated with the frontend of the linear part, and the tail end and the front end are integrated into one. The diameter of the bending part is smaller than that of the linear part, the front end of the bending part is provided with an arc-shaped end head, the outer side of the top end of the bending part is also provided with a first air bag, and the first air bag is communicated with the bending part through an air inlet hole. Compared with the prior art, the probe is provided with the detachable hand-held handle, an air bag is arranged in the hand-held handle, and the first air bag at the end part of the urethralprobe is inflated through the hand-held handle, so that the urethral probe can be expanded, the circumference of the urethral probe can be increased without being replaced, the probe is convenient touse and convenient to the clinical diagnosis and treatment.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a urethral probe with adjustable circumference. Background technique [0002] Urethral stricture and obstruction are common diseases in urological surgery. Urethral expansion or indwelling catheterization is usually required. However, the circumference of each urethral probe currently used is fixed, and only multiple different probes can be used for urethral examination or urethral dilation. The operation of different types of probes is rotated, and the operation and instrument preparation and disinfection are complicated. At the same time, due to the hardness of metal probes, dilation with large-diameter urethral probes often fails to expand, and may even cause urethral injury and iatrogenic urethral false passages. Severe complications such as the formation of even rectal perforation bring certain difficulties to clinical diagnosis and treatment. Contents of the invention ...
