Abstract

The utility model belongs to the technology of a medical appliance. A Catheter urethral reunion device which is produced by the utility model is composed of an elastic catheter which is made of silicon plastic materials and two hollow sleeve pipes which are made of metallic materials. Two ends of the catheter are circular blunt structures, the front parts of the two sleeve pipes present cambered bent structures, and orientation pieces are arranged on the rear parts of the two sleeve pipes; the pipe diameters of the two sleeve pipes are different, and the front ends of the two sleeve pipes are combined in cuttage grafting way. The utility model can be used for carrying out reconstruction of ruptured prostatic urethra to cause patient's wound to be reduced to minimum limit, and the utility model can be used without limit by operations and conditions of state of illness. The utility model has the advantages of easy operation and short operation time.

Description

Conduit urethral realignment device

This utility model belongs to technical field of medical instruments, mainly proposes a kind of conduit urethral realignment device, is used for the emergency treatment urethral reunion operation of traumatic urethral disruption and urethra via the treatment that forms.

Due to the traumatic fracture of pelvis of urethral disruption polyphyly, the state of an illness is critical and anxious.Because two broken ends of fractured bone dislocation can't be inserted in the bladder cavity from intraurethral cannula, need two broken ends of fractured bone to join forces just to make catheter enter bladder to urinate behind the urethral disruption.Urethral reunion operation is by the surgical incision bladder, probe into the urethra broken ends of fractured bone with metal divulsor or metal urethral catheter from external orifice of urethra, cut bladder again and probe into after the urethra broken ends of fractured bone joins from internal urethral orifice with finger, will the metal divulsor under the guiding of finger or metal urethral catheter introduce in the bladder cavity and finish urethral reunion operation.The existing defective of this method is: 1, a kind of common but severe complication due to the urethral disruption polyphyly fracture of pelvis, the state of an illness is critical, and the danger that increases the weight of wound is arranged when moving.2, need operating room and good anesthesia condition, and need a complete set of surgical staff close fit to finish.3, there is hematoma outside the basin sacrum of popularity and the abdominal cavity in fracture of pelvis posterior urethral rupture majority, oozes out, in case stomach wall and peritoneum open, hemorrhage wayward, and have and increase the chance that infects.4, (as shock state) can't in time perform the operation and finish urethral reunion operation under the situation of state of an illness especially severe, when influence is rescued to the observation of urine amount.

The purpose of this utility model promptly is to propose a kind of conduit urethral realignment device, can make patient's wound minimize and not be subjected to operation and state of an illness condition restriction by this device row urethral reunion operation, and have easy and simple to handle, the characteristics that operating time is lacked.

This utility model is finished the technical scheme that its invention task taked: the hollow bushing of its elastic catheter by a silicon moulding material, two metal materials is formed; The elastic catheter two ends is the blunt structure of circle, and two telescopic front portions are the arc bending structure, and the rear portion has orienting piece, and two telescopic front ends are the grafting combination.

This utility model catheter cannula is in conjunction with explanation:

1, through punctio vesicae conduit is sent in the bladder cavity, under the guiding of conduit, sleeve A imported in the bladder cavity and with conduit and be retracted into sleeve pipe head intracavity, the casing head of sleeve A is probeed into internal urethral orifice to the urethra broken ends of fractured bone according to the orientation mark of sleeve A afterbody.

2, from external orifice of urethra sleeve pipe B is probeed into the urethra broken ends of fractured bone, sleeve A and sleeve pipe B two sleeve pipe head ends are met at urethra broken ends of fractured bone place, and they are pegged graft mutually in conjunction with (little caliber is inserted in the pipe of big caliber), be inserted in metastable position.

3, after two casing heads are met and are inserted in, the conduit of sleeve A afterbody till sleeve pipe B intracavity is advanced into sleeve pipe B afterbody and sees conductor housing, is finished the catheter cannula combination.

This utility model catheter cannula is joined forces the operation of the capable urethral reunion operation of device:

1, patient's clinostatism of making even, the wild skin of routine disinfection art is put aseptic aperture towel.

2,2% lignocaine 5ml, the capable mucous membrane of urethra anesthesia of 2% lignocaine 5-10ml or lubricated amyl colloid is injected in 2-3cm place local infiltration anesthesia on the pubic symphysis in the urethra.

3, get on the pubic symphysis 2-3cm place and reach the abdominal muscle protheca deeply, (cutting skin holostrome and theca of rectus abdominis muscle) with the straight thrust of sharp knife sheet.

4, thrust straightly in the bladder cavity with small size (diameter 4mm) punctio vesicae pin, see the urine discharge, withdraw from the punctio vesicae nook closing member, conduit is sent in the bladder cavity, withdraw from the punctio vesicae stylophore.

5, sleeve A is imported in the bladder cavity under lead in the hole of conduit, and conduit is retreated to sleeve pipe head intracavity.

6, the orienting piece of sleeve A is aimed at the pubic symphysis direction, make casing head probe into internal urethral orifice, and enter the back urethra, the sense that falls through commonly used this moment to the urethra broken ends of fractured bone.

7, from external orifice of urethra sleeve pipe B is probeed into the urethra broken ends of fractured bone, two sleeve pipe heads are joined at urethra broken ends of fractured bone place, move at two have gentle hands degree and to make two casing heads patch combination under the adjusting, and two casing heads are positioned on the same axis, till feeling to push ahead the conduit of sleeve A afterbody when sleeve pipe B afterbody is seen conductor housing after relatively stable.

8, withdraw from sleeve pipe B, after conductor housing and Foley catheter top are connected firmly, under the guiding of conduit, Foley catheter introduced in the bladder cavity and air bag is full.

9, pull out conduit and sleeve A, finish with adhesive bandage or dressing dressing punctio vesicae mouth sterilization back.Postoperative can be done suitable urethra traction, is beneficial to broken ends of fractured bone urethra and joins.

By the capable urethral reunion operation of conduit urethral realignment device of the present utility model, make patient's wound reduce to lowest limit degree, and be not subjected to operation and state of an illness condition restriction, make hinder the back urine can not discharge voluntarily due to the urinary retention person, no matter all can implement urethral reunion operation in outpatient service or ward, do not need to send into specially operating room, scutching is liquor-saturated moves patient and a complete set of surgical staff cooperates back and forth.Only need one man operation under local anaesthesia, can finish urethral reunion operation.Use this utility model apparatus, easy and simple to handle, wound is little, and operating time is short.
