Description
Technical field
The invention belongs to Medical teaching technical field of mold, and modular human urethra end end kiss can be substituted by being related to one kind from group
Emulation operation simulation trainer is closed, specially a kind of surgical simulation training aids of urethra reconstruction operation.
Background technique
Ankylurethria is that Urology Surgery is more typical and a kind of disease difficult to deal with, disease incidence are 300~6,00/,100,000,
Domestic last decade disease incidence, which is presented, continues raised situation.But urethra reconstruction because its operating difficulty is big, technical requirements are high, at
The feature that power is low and postoperative complications are mostly equal, it is normal more intractable in clinical practice processing.
Male urethra is about 16~22cm, caliber 5~7mm of average out to from the urethral orifice of bladder neck to orificium urethrae externum, can
It is divided into pars cavernosa urethrea virilis, bulb, film portion and prostatic part.Newest he result of investigation shows, the traumatic ankylurethria ratio in China
Example highest up to 51.76%, and is largely focused on bulb and membranous urethra damage.Be primarily due to patient fallen by eminence or
When falling down, perineum is ridden on hard object, and bulbous urethra is squeezed between hard object and lower margin of pubic bone and urethra occurs
Damage, the patient after the damage of 10% or more bulb can finally develop as ankylurethria.In addition to this, with urethra endoscopic surgery
It continues to develop and popularizes, iatrogenic injury also becomes the Important cause of disease for causing bulbous urethra narrow, and ratio reaches 34.49%,
Through close to Hesperian disease incidence.Operation is the best mode of thorough treatment ankylurethria, and urethroplasty is still considered as
" goldstandard " of current ankylurethria treatment.It is narrow for bulb, film portion and proximal end prostatic urethra at present, main hand
Art mode is end-to-end anastomosis of urethra the most classical.According to existing report, this technology is treatment bulb and all kinds of Posterior urethrals
Narrow middle success rate highest and the most specific modus operandi of effect are the bases that Urology Surgery grasps urethral disease related surgical.
But the treatment level of urethral disease is there are apparent regional differences in China's range at present, and basic hospital is because accept for medical treatment less than phase
The patient for answering quantity, the urethra reconstruction operation for causing Urology Surgery doctor to do, especially urethra end to end anastomosis technology is less,
Doctor cannot get enough exercises, cause clinical practice curative effect not fully up to expectations.Although and training Grade A hospital can be inhaled every year
A large amount of urethral disease patient is received, but technically carries out and monopolizes in the industry, only a small amount of periphery hospital doctor can obtain clinic
On guidance, limit the widely available of such technology.
Therefore, a kind of fidelity height is developed, the emulation surgical simulation instruction of more real simulation end-to-end anastomosis of urethra is capable of
Practice the great realistic meaning of device.
Summary of the invention
