Problems solved by technology

The former has a large surgical trauma and a high incidence of postoperative ED. Although the latter surgical trauma is small, it is blind to the operation for patients with complete urethral atresia, which is likely to cause damage to the false tract and rectum, and the probability of conversion to open surgery increases.
Whether it is open surgery or endovascular surgery, the cost is mostly more than 10,000 yuan, which brings huge economic burden and mental trauma to the patient.

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] A urethral dilator, including an anterior urethral dilator and a posterior urethral dilator, such as figure 1 , figure 2 , image 3 , Figure 4 As shown, wherein, the front urethral dilator is composed of a hollow probe body 1 and a handle 2 arranged on the probe body 1, the rear urethral dilator includes a sheath body 3, and the rear end of the sheath body 3 is provided with an inner hole 4, and the sheath body 3 The front end is provided with a guide hole 5, and a cup mouth 6 is arranged in the guide hole 5, and the cup mouth 6 communicates with the inner hole 4.

[0027] The sheath body 3 is arc-shaped.

[0028] Use: For urethral stricture with complete urethral atresia, if the narrow length is short, the device of the present invention can be used to complete urethral dilation, so that the patient can be exempted from surgery. If the length of the sten...

Abstract

The invention discloses a urethral expander, which comprises a front urethral expander and a back urethral expander, wherein the front urethral expander consists of a hollow probe body and a handle arranged on the probe body; the back urethral expander comprises a sheath body; the back end of the sheath body is provided with an inner hole; the front end of the sheath body is provided with a guidehole; and a cup rim is arranged in the guide hole, and is communicated with the inner hole. When the urethral expander is in use, during expansion, the front urethral expander and the back urethral expander break through a narrow part of a urethra and are converged on the urethra, and the pointed end of the front urethral expander is clamped into the cup rim of the back urethral expander, so thaturethra expansion operation is completed. The invention has the advantages: the front urethral expander is put into a front urethra and the front end of the front urethral expander is clamped into the cup rim at the front end of the back urethral expander to form a semicircular structure, and the front and back urethral expanders are combined and connected into a whole, so that normal position ofthe urethral expander can be judged easily, and damage to the urethra and the formation of a false passage are avoided.

Description

technical field [0001] The invention relates to a urethral dilator, which belongs to the technical field of medical instruments. Background technique [0002] Urethral stricture is a common disease in urology, and its causes are usually divided into three categories: traumatic factors, inflammatory factors, and congenital factors. The lesions mainly manifest as scars of different depths and densities, accompanied by urothelial defects and contractures of the tube wall, which finally affect normal urination. The simplest and most common method of treating urethral strictures is urethral dilatation, which uses a metal urethral probe to dilate the narrowed urethra. It can be performed in primary medical units, and the medical cost of urethral dilation is about one or two hundred yuan, which is acceptable to most patients. However, due to various reasons, the failure of urethral dilation often occurs, and even serious complications such as urethral hemorrhage and iatrogenic ur...
