Embodiment 1

[0041] A guided urethral protection expansion device, which is a guided urethral protection expansion device, including an expansion structure 2 sleeved on the front end of the urethroscope body 1 for guiding the urethroscope body 1 into the urethra; the expansion structure 2 and the urethroscope body 1 are detachably connected, and the expansion structure 2 can slide back and forth along the axial direction of the urethroscope body 1.

[0042] The expansion structure 2 includes two connecting parts 2-1 and two guiding parts 2-2; the two connecting parts 2-1 are detachably connected, and the two connecting parts 2-1 are snapped together. When the expanding structure 2 After the auxiliary urethroscope body 1 enters the urethra, the expansion structure 2 is conveniently removed from the urethroscope body 1 through the clamping effect between the two connecting parts 2-1, and it is not easy to hinder the follow-up inspection work of the urethroscope body 1 , the two connecting pa...

Embodiment 2

[0050] see Figure 1-7 , the number of mounting holes 2-1-2 is two groups, and the distance between the two groups of mounting holes 2-1-2 does not exceed 1.5cm; through the setting of two groups of mounting holes 2-1-2, when the second extrusion When the elastic soft sheets 2-1-5 deform and protrude the first elastic soft sheets 2-1-4, one group of the first elastic soft sheets 2-1-4 is located in the urethra, and the other group of first elastic soft sheets 2-1 -4 Located outside the urethra, the expansion structure 2 can be better fixed near the urethral opening, and it is not easy to cause the expansion structure 2 to enter the urethra too deeply due to misoperation, or the expansion structure 2 entering the urethra to slip out of the urethra due to misoperation outside.

Embodiment 3

[0052] see Figure 8 An elastic connection part 4 is fixed between the inner surface of the guide part 2-2 and the front end of the connection part 2-1. The elastic connection part 4 can be an elastic connection belt, and the elastic connection part 4 is used to limit the relative connection part of the guide part 2-2. The rotation angle of 2-1, through the setting of the elastic connecting part 4, when the urethroscope body 1 pushes forward to gradually push away the two guiding parts 2-2 that are close to each other, under the elastic force of the elastic connecting part 4, guide The part 2-2 is not easy to rotate around the connecting part 2-1 at an excessive angle and cannot return to its original position, or the distance between the two guiding parts 2-2 is too large due to the excessive rotation angle, and the expansion structure 2 cannot exit the urethra .

Abstract

The invention discloses a guide type urethra protection expansion device, and belongs to the technical field of medical auxiliary instruments. A guiding type urethra protection expansion device comprises an expansion structure which is arranged at the front end of a urethroscope body in a sleeving mode and used for guiding the urethroscope body to enter a urethra. The expansion structure is detachably connected with the urethroscope body, and the expansion structure can slide back and forth in the axis direction of the urethroscope body; a deformation structure is arranged on the expansion structure, and the deformation structure can deform after being extruded by the outside to fix the expansion structure on the urethral orifice; a limiting structure is arranged between the expansion structure and the urethroscope body and used for controlling relative sliding between the expansion structure and the urethroscope body, the urethroscope body can be guided to be inserted into the urethra, the problem of mucosa damage caused by repeated urethra friction is not prone to occurring, pain of a patient is relieved, the patient is easy to recover after an operation, and the urethroscope is convenient to use. Meanwhile, the operation efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, and more specifically, relates to a guided urethral protection expansion device. Background technique [0002] The application of urethroscopy in the medical field is relatively common. When a patient suffers from a sudden illness and cannot urinate, or needs treatment such as intubation of the urethra, it is often necessary to observe the structure of the urethra with the help of a urethroscope, so as to perform corresponding operations such as intubation. [0003] Clinically, urethral stricture requires repeated urethral dilation. At present, metal dilators are used, which need to be blindly expanded at least three times to enter and exit the urethra. The process of repeatedly entering and exiting the urethra is likely to cause damage to the urethral mucosa. In severe cases, false passages, Complications such as massive urethral bleeding increase the pain of the patient and...
