Technical field

The utility model belongs to technical field of medical instruments, more particularly to a kind of extension fixture for ejaculatory duct obstruction.

Background technology

The obstruction at the remote testis end in ejaculatory duct obstruction Shu Jing roads, the cause of disease has congenital and posteriority, obstructive infertility caused by it Account for the 1%-5% of male sterility.Main clinic symptoms are painful ejaculation, blood sperm, scrotum pain, perineum discomfort, chronic pelvic Pain, ejaculate weak, lack of quantity of spermatic fluid and urethral orifice exception, small part patient can be associated with epididymitis or vesiculitis.But it is traditional Per urethra ejaculatory duct cut there is open defect, the operation generally require to climb using TURP needed in TURP seminal colliculus, art grasp electricity The depth and scope cut, while observing surgical wound surface whether there is milky, brown, yellowish-brown or dark red solution outflow, to determine Whether bilateral ejaculatory duct is exposed, and the experience and operation to patient require higher, while in the presence of higher postoperative complications, it is such as postoperative Scar is formed, and urine is backflowed, seminal fluid is thin, blood urine, epididymitis, smart road vasculitis, the urinary incontinence or perforation of rectum etc..To patient with Carry out endless worried and pain.And so many complication also brings huge burden to nursery work.

Utility model content

In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is that ejaculation can effectively be expanded by providing one kind Pipe narrow section, a kind for the treatment of extension fixture for ejaculatory duct obstruction that ejaculatory duct obstruction effect is good, patient suffering is small.

To realize above-mentioned technical purpose, the technical scheme that the utility model is taken is：

A kind of extension fixture for ejaculatory duct obstruction, wherein：Seminal vesicle inserting tube including ejaculatory duct can be inserted, seminal vesicle inserting tube An axially extending division board is inside provided with, seminal vesicle inserting tube inner chamber is divided into division board into observation chamber and expansion pipe accommodates chamber, sees The front end for examining chamber is provided with high printing opacity object lens, and high printing opacity object lens are by the external central processing unit of visual optical fiber, on central processing unit Display is provided with, the image that high printing opacity object lens are clapped shows that the extension fixture for ejaculatory duct obstruction is also wrapped over the display Expansion pipe and push rod are included, expansion pipe is to be provided with several on flexible pipe prepared by degradation material, the tube wall for expanding pipe to run through The expansion that the making of several water uptake expansion materials is additionally provided with through hole inside and outside tube wall, the outer tube wall for expanding pipe is raised, expands Pipe can insert expansion pipe and accommodate in chamber in the dry state, and slip in chamber can be accommodated in expansion pipe, and push rod can be from expansion pipe The rear insertion expansion pipe for accommodating chamber is accommodated in chamber, and can will be had been placed on expanding pipe and accommodated expansion pipe in chamber and put from expansion pipe Receive chamber front end release.

For optimization above-mentioned technical proposal, the concrete measure taken also includes：

The material of above-mentioned expansion pipe is polyurethane.

The raised material of above-mentioned expansion is water-absorbing resin.

Above-mentioned high printing opacity object lens are objective glass lenses or translucent silica gel object lens.

The forward end seal of above-mentioned high printing opacity object lens and observation chamber coordinates.

Above-mentioned central processing unit is PC.

At present still not in ejaculatory duct using the precedent for expanding pipe, however, it is contemplated that expansion pipe is put into one in ejaculatory duct After the section time, in addition it is also necessary to taken out from ejaculatory duct, although operating difficulty is not high, but patient can be agonizing, more seriously A certain degree of damage can be caused during tube drawing to ejaculatory duct, infection and other complication, therefore, the utility model are brought it about Using a kind of expansion pipe of degradable material as ejaculatory duct, after a period of time, expansion pipe can degrade automatically, into urethra Discharge, the trouble that pipe takes out will be expanded by eliminating.Because expansion pipe is that flexible material makes, need to together it enter with seminal vesicle inserting tube Ejaculatory duct, therefore, the caliber of expansion pipe can be more narrower compared with ejaculatory duct, and the utility model is provided with numerous suctions outside expansion pipe The expansion that water-resin makes is raised, and when expansion pipe is left in ejaculatory duct, water-absorbing resin water swelling can effectively improve expansion Pipe external diameter, swells narrow ejaculation pipeline section, when expansion pipe degraded, and water-absorbing resin is raised to enter urethra with expansion pipe fragment Numerous through holes are provided with discharge, expansion pipe, seminal fluid and prostatic fluid is passed through expansion pipe and enters urethra.

Embodiment

Embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing.

A kind of extension fixture for ejaculatory duct obstruction of the present utility model, wherein：Seminal vesicle including ejaculatory duct can be inserted An axially extending division board 11 is provided with inserting tube 1, seminal vesicle inserting tube 1, the inner chamber of seminal vesicle inserting tube 1 is divided into observation by division board 11 Chamber 12 and expansion pipe accommodate chamber 13, and the front end of observation chamber 12 is provided with high printing opacity object lens 2, and high printing opacity object lens 2 pass through visual optical fiber 3 Display is provided with external central processing unit 4, central processing unit 4, the image that high printing opacity object lens 2 are clapped shows over the display Show, the extension fixture for ejaculatory duct obstruction also includes expansion pipe 5 and push rod 6, expansion pipe 5 is flexibility prepared by degradation material It is provided with several through holes 51 inside and outside tube wall, the outer tube wall for expanding pipe 5 and also sets up on pipe, the tube wall for expanding pipe 5 There is the expansion projection 52 that several water uptake expansion materials make, expansion pipe 5 can insert expansion pipe and accommodate chamber 13 in the dry state In, and can be slided in expansion pipe accommodates chamber 13, the rear insertion expansion pipe that push rod 6 can accommodate chamber 13 from expansion pipe accommodates chamber 13 In, and can will have been placed on expanding pipe and accommodate the front end release that expansion pipe 5 in chamber 13 accommodates chamber 13 from expansion pipe.

In embodiment, the material of expansion pipe 5 is polyurethane.
