Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a novel urethral probe. Background Art

[0002] With the arrival of an aging society in China, the number of elderly men suffering from prostate hyperplasia is increasing, and the number of patients undergoing surgical treatment for prostate hyperplasia is also increasing year by year. In the process of prostate surgery, indwelling a urinary catheter is an indispensable process throughout the operation. However, during the operation, the urethral continuity of the prostate segment is artificially changed by the surgery. During the process of indwelling a urinary catheter, it is often necessary to use a urethral probe or guidewire to successfully place the catheter.

[0003] Indwelling urinary catheter is an invasive procedure that requires the catheter to be inserted into the human urethra. Male patients are prone to difficulties in catheterization, which leads to the failure of successful catheterization and the need for repeated catheterization. This may cause damage to the urethral mucosa such as edema and increase the chance of infection, causing unnecessary pain to male patients, increasing their psychological burden and affecting their quality of life.

[0004] Currently available urethral probes are mostly a combination of a bougie and a handle, and the bougie is relatively short and thick. When encountering patients with relatively long penises, the bougie cannot be implanted into the bladder, resulting in failure of indwelling urinary catheterization. The metal probe is thick and hard, which can easily cause false passages, damage physiological structures, or cause urethral damage, bleeding, infection, etc., and the bougie cannot be inserted into the lumen. The bougie and the urinary catheter are not on the same axial plane, and the urinary catheter is easy to fall off. The handle cannot fix the urinary catheter. When using the existing urethral probe to place a urinary catheter, one hand fixes the direction of the penis, and the other hand needs to fix the direction of the urethral probe and fix the urinary catheter to prevent it from falling off. The strength of inserting the urinary catheter must also be controlled. If the three forces cannot be balanced, the urinary catheter cannot be successfully placed.

[0005] Therefore, a novel urethral probe is proposed to solve the existing deficiencies. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned technology and provide a novel urethral probe.

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is a new type of urethral probe: comprising a bougie, a handle and a urinary catheter fixer;

[0008] A U-shaped groove is provided at one end of the handle along its axial direction, a plug hole is provided at the end of the U-shaped groove, a through hole connected to the plug hole is provided at the other end of the handle, and urinary catheter fixers are provided on both sides of one end of the handle located at the U-shaped groove away from the plug hole;

[0009] The bougie is a hollow structure, comprising an integrally formed bougie body and an arc-shaped end portion, one end of the bougie body being inserted into the plug-in hole, and a damping ring cooperating with the bougie body being provided in the plug-in hole;

[0010] Also included is a guide wire, which is inserted into the bougie through the through hole.

[0011] As an improvement, the plug hole and the through hole are coaxially arranged.

[0012] As an improvement, the end of the arc-shaped end away from the body of the bougie is a ball head structure.

[0013] As an improvement, the urinary catheter fixer is located on both sides of the U-shaped groove and is symmetrically arranged, and the urinary catheter fixer is located above the bougie.

[0014] As an improvement, the handle is provided with bosses on both sides of the U-shaped groove.

[0015] The advantages of the utility model compared with the prior art are:

[0016] 1. The detachable setting of the handle and the bougie facilitates the control of the direction of the bougie when the bougie is inserted, and facilitates the insertion of the bougie in the urethra. It is also convenient to separate the bougie from the handle after the catheterization is completed, so as to facilitate the removal of the bougie from the catheter.

[0017] 2. The U-shaped groove and the catheter holder are used to fix the tail end of the catheter on the bougie, so that the catheter and the bougie are relatively stable, which can avoid the need to control the fixation of the catheter on the bougie during the catheterization operation, and effectively prevent the catheter from falling off during the catheterization operation;

[0018] 3. Through the setting of the guide wire, the strength of the bougie can be adjusted according to the actual situation of the catheter insertion operation to meet the use requirements in different situations;

[0019] 4. The urethral probe has a simple structure and is easy to use. It can quickly, safely and effectively insert a urinary catheter, reduce the risk of urethral injury, and shorten the operation time. BRIEF DESCRIPTION OF THE DRAWINGS
