In the description of the present application, the terms "first", "second", and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated.

The traditional traction procedure for the urethra symptomatologist mainly comprises the steps of making a middle incision on the lower abdomen, exposing the front wall of the bladder and the gap behind the pubic bone, removing hematoma and exosmosis urine, and stopping bleeding. The bladder is cut open and its urine is aspirated. A metal catheter or urethral probe is inserted through the external orifice of the urethra with its tip reaching the injured part of the urethra. The operator inserts the urethra and the urethral sound consultation organ (figure 1) through the bladder incision by using the guide finger; under the guide of the index finger, the urethral probe is inserted into the probe from the external urethral opening and is guided into the bladder (see figure 2), and the index finger of the operator is required to extend into the bladder, and the urethral probe meet the physician after being inserted through the bladder incision, so that the incision is required to have enough size to meet the requirement that the index finger of the operator and the hand part enter the bladder 20, the wound surface of the incision is large, the recovery time of a patient is prolonged, the operation is inconvenient and the like.

Based on this, the application provides a dilator for a urethra consultation organ, comprising

The urethral probe 10 is provided with a probe body with a smooth surface, and the top of the probe body is a hemispherical probe body;

a guide probe 30 having a smooth-surfaced guide probe body, the top of which has a hemispherical recess corresponding to the probe body, the probe body being receivable within the recess.

The guiding probe 30 is used for replacing the index finger of the operator, so that the defects of the index finger used in the traction operation of the traditional urethral reunion physician are improved and compensated, the convenience of the operation is improved, and the wound surface of the incision of the patient is reduced; by adopting the structure that the concave part is arranged at the top of the guiding probe 30, the urethral probe can stably and reliably follow the guiding probe in the guiding process, and the guiding failure caused by dislocation or deflection of the urethral probe is avoided.

Specifically, the probe body is of an integral metal structure and comprises a handle part 13, a straight pipe part 11 and a bent part 12, wherein the handle part 13, the straight pipe part 11 and the bent part 12 are sequentially connected, and the handle part 13 is used for holding, preferably, the handle part 13 is flat, so that the holding is more convenient.
