Lithotripsy device for soft ureteral channel

Abstract

The invention relates to a urethral lithotripsy device with a soft channel. The urethral lithotripsy device comprises a soft channel device, a light guide assembly, a draw bar assembly, a lifter, a soft lens assembly and a holmium laser assembly. The soft channel device comprises a channel seat and a soft tube channel, one end of the soft tube channel is fixed onto the channel seat, a channel head is arranged at the other end of the soft tube channel, a channel opening is formed in the channel head, and a transparent sheet is fixed onto the channel opening; a soft steel wire is arranged in the soft tube channel, one end of the soft steel wire is fixed onto the channel seat, and a distance from the other end of the soft steel wire to the channel opening ranges from 4cm to 5cm; the holmium laser assembly, a soft lens channel, a light guide cable channel and a draw bar channel are arranged in the soft tube channel. The urethral lithotripsy device has the advantages that the urethral lithotripsy device is reasonable in structural design, the soft tube channel is soft and is easy to operate, and accordingly pain can be prevented for patients; the urethral lithotripsy device is wide in operation visual field, various directions can be taken into consideration, and accordingly the surgery efficiency can be improved.

Description

technical field [0001] The invention relates to a lithotripsy device for a ureteral soft channel, which is specially used for treating calculi in the urethra of a human body and belongs to the technical field of medical devices. Background technique [0002] The urethra is the detoxification system of human beings. There are many toxins and sediments in the urine. The urine is filtered into the urethra through the kidneys. During this metabolic process, the kidneys and urethra often form sediments, which will cause kidney and urethral stones for a long time . In the process of drug treatment, kidney stones form and separate from the kidneys, and the stones enter the urethra, resulting in urethral stones. The invention is a soft urethral mirror and a soft channel lithotripsy system specially used for carrying out holmium laser lithotripsy in the human urethra.

AI Technical Summary

Problems solved by technology

[0003] Therapeutic method of prior art: the one, carry out urethral lithotripsy with medicine treatment, excrete naturally during urination, its shortcoming is the time of lithotripsy is long, if calculus is too big and difficult to crush stones, cause urethral blockage, bring pain to the people

Second, there are also urethral lithotripsy devices, such as urethral lithotripsy devices, holmium laser lithotripsy devices, and urethral lithotripsy forceps. It is difficult to enter the urethra; the head cannot be turned, and the cystoscope only has a straight-line view. After entering the human bladder, the operating channel of the instrument must be swung to improve the angle of view. The operation is troublesome; the operating channel of the metal hard tube cannot be turned, so it is limited to the operation of the human urethra and bladder. , such as entering the human kidney with a small field of view and a small operating space, which cannot meet the ideal surgical effect
