Description
Technical field
The utility model relates to the field of medical instrument technology more particularly to a kind of mucous membrane of urethra anaesthesia apparatuses.
Background technique
With the pollution of social senilization and alleviation, the disease of the patients such as calculi in urinary system, hyperplasia of prostate, prostate cancer
Number is more and more.Modern urological surgery is largely replaced by minimally invasive hysteroscope, especially cystoscope, ureteroscope, abdomen
Hysteroscope.
Cystoscope and ureteroscope need to enter operative site from the urethra of human body, it is generally known that, the distribution of urethra epineural
Intensively, Hyperalgesia.Official jargon is narrow, the crisp easy bleeding of matter.Therefore, how simply, quickly, it is safe and effective anesthesia be operation
Premise.Effective anesthesia, the medical treatment cognition and Cooperation in operation of patient comfort can reduce iatrogenic injury well, and it is fast to reach safety
The purpose of fast diagnosis and treatment.
Under existing medical condition, lack a kind of safe and effective urethra anesthesia device, so that often discontented in anesthesia in patient
It performs the operation in the state of meaning, patient's stress act because of involuntary pair of pain stimulation of pain, frequently results in art and urinate in art
Road damage, bleeding, via formation, post-surgical trauma irritability syndrome is not able to cooperate operation and smoothly completes.
Currently, clinically mainly taking following method to per urethra endoscope-assistant surgery:
1. the mirror sheath that per urethra enters bladder is directly inserted into bladder, mucous membrane of urethra from urethral orifice after showing to smear paraffin oil
It does not anaesthetize, pain stimulation is obvious when being inserted into operation in camera lens and art, seriously affects in art and operates.Due to human urethra have it is narrow
It is narrow and bending, iatrogenic urethral rupture and via formed it is clinically very common, to patient bring it is unnecessary pain and after
Lose disease.
2. being inserted into urethra after picking anesthesia liquid with cotton swab to reach anesthetic effect, anesthetic effect is small, and urethra anesthesia
Depth is inadequate.
3. spurting into urethra in urethral orifice by force after drawing anesthesia liquid with injector.Disadvantage is it is obvious that first, to urethra
Many drugs can overflow urethral orifice when mouth spray anaesthetic, drug resource be wasted, second, the depth of anesthesia of urethra is difficult handle
Hold, many times distal urethra mucomembranous anesthesia less than or anesthesia be not thorough.
