Interior fixation, described convert are additionally provided with injection interface 5 on sub- connector；
First stainless steel tube 2 and 3 front end of the second stainless-steel pipe are not connect with the sub- connector 1 of conversion, and first not
The lumen of rust steel pipe 2 and the second stainless-steel pipe 3 is all connected to the injection interface 5, and two stainless steel tubes successively include parallel
Section 6, diagonal diverge to section 7 and diverge to parallel-segment 8；
The injection needle 4 includes stitch 41, needle arm 42 and syringe needle 43, and there are two the stitch 41, and two stitch 41 are mutual
It is plugged on the end of the first stainless steel tube 2 and the second stainless-steel pipe 3 in parallel and respectively, in addition, 41 end of stitch is respectively connected with
The needle arm 42 of bending, two needle arm 42 mutually converge connection in 42 end of needle arm, and, and syringe needle 43 and two needle arm 42 are converged
It is whole in Y-shape after place's connection.
In the present embodiment, 6 terminal position of parallel section of first stainless steel tube 2 and the second stainless-steel pipe 3 is equipped with solid
Fixed rack 9, fixed bracket 9 are to have cylinder-like structure jaggy, and fixed bracket 9 is for maintaining bladder resectoscope and two stainless steels
The relative position of pipe.
Specifically, the caliber of first stainless steel tube 2 and the second stainless-steel pipe 3 is 1.3mm, between two needle arm 42
Angle is 120 °, and the angle of needle arm and syringe needle is respectively 120 °, wherein a length of 3.0mm of syringe needle, needle diameter 0.6mm, stitch,
Needle arm and syringe needle are stainless steel tube structure.In addition, the syringe needle 43 and the first stainless steel tube 2 and the second stainless-steel pipe 3
The angle α for diverging to 8 place plane of parallel-segment is obtuse angle, parallel mucous membrane when being convenient for inserting needle, more specifically, angle α be 125~
135°；In this case, it combines the operation for swinging bladder resectoscope that syringe needle can be achieved by driving handle to put down in submucosal multiple spot
Traveling needle, such as side wall, rear wall, the injection in the regions such as trigonum.Meanwhile this angle it is also ensured that be pierced into when syringe needle
It can be in the visual field center of bladder resectoscope, convenient for visual lower piercing operation, in order to further ensure syringe needle is in the visual field, two
The diagonal of stainless steel tube diverges to section 7 and extends 6mm, so that parallel section 6 and diverging to the common cutting ring of relative distance ratio between parallel-segment 8
This relative distance it is big, and single unit system length also has extension.
It, first should will be according to common etc. when inject under mucous membrane of urinary bladder using the mucous membrane of urinary bladder injection device of the utility model
The present apparatus is mounted in the driving handle of bladder resectoscope by the installation method of ion cutting ring, is entered with bladder resectoscope
Mirror sheath.
It converts after sub- connector 1 is stuck in driving handle, can generate and promote or spinning movement with driving handle；It is being moved through
