Urethra anesthetic sprayer capable of expanding urethra for urinary surgery

Abstract

The invention discloses a urinary surgery urethra anesthetic sprayer capable of expanding the urethra, and relates to the technical field of medical instruments, the urinary surgery urethra anesthetic sprayer comprises an anesthetic catheter, an annular urine collecting tube is arranged on the outer side wall of the anesthetic catheter, and a control box and a first connecting tube are arranged at the end of the annular urine collecting tube; the first connecting pipe is located in the control box body, a urine collecting bag is arranged at the end, away from the annular urine collecting pipe, of the first connecting pipe, and the top of the urine collecting bag is connected with the bottom of the control box body; and a plurality of annular expanding bags are arranged on the outer side wall of the annular urine collecting pipe and distributed at equal intervals in the inserting direction of the annular urine collecting pipe. The urinary surgery urethra anesthetic sprayer not only can be used for anesthetizing the whole section of urethra, but also can be used for expanding the urethra step by step under the condition that the urethra dilator is not taken out, in addition, the anesthetic spraying device can also guide urine in the bladder to indicate whether the spraying device enters the bladder or not, the anesthetic of the whole section of urethra is ensured, and the situation that the urethra enters or forms a false channel during urethra dilation is avoided.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, it relates to a urethral anesthesia sprayer for urology that can expand the urethra. Background technique [0002] In long-term clinical trials, it is necessary to inject anesthetics into the urethral orifice to anesthetize and lubricate the urethra before examining the urethra or bladder of patients in urological surgery, so as to facilitate the inspection equipment to enter the urethra. , but there are the following deficiencies: [0003] 1. The catheter of the anesthetic tank is usually a straight tube with a length of about 8 cm, which can only reach the bulbar urethra through the penile urethra. Therefore, the anesthetic usually only covers the penis and bulbar urethra and is difficult to enter the posterior urethra, resulting in insufficient anesthesia. Strong pain during transurethral manipulation; [0004] 2. At present, urethral expansion needs to be expa...

AI Technical Summary

Problems solved by technology

[0003] 1. The catheter of the anesthetic tank is usually a straight tube with a length of about 8 cm, which can only reach the bulbar urethra through the penile urethra. Therefore, the anesthetic usually only covers the penis and bulbar urethra and is difficult to enter the posterior urethra, resulting in insufficient anesthesia. Strong pain during transurethral manipulation;

[0004] 2. At present, urethral expansion needs to be expanded step by step, and multiple urethral bougies with gradually thicker diameters need to be inserted into the urethra one by one. Repeated insertion into the urethra will increase the pain of the patient, and increase the difficulty of operation and the incidence of complications;

[0005] 3. At present, urethral dilation is mainly based on blind expansion. The operator judges whether the dilator has entered the bladder based on the feel and depth, which may easily lead to the false tract and mistakenly think that it has entered the bladder, resulting in urethral injury or even the risk of urethral rupture.
