Description
Technical field
The utility model is related to urological department apparatus field, specifically a kind of urethral puncture injection needle.
Background technology
It is current, when clinically there are the symptoms such as hyperplasia of prostate, ankylurethria, nerve urinary hesitancy, urination can be caused tired
Hardly possible to urethral wall, it is necessary to carry out direct injection.When clinically needing to carry out direct injection in urethra with injection needle at present, lack
Corresponding suitable instrument used for injection, head end is sharp, and urethra is injured into easy during urethra, and it is difficult in ultrasound that injection needle, which enters after urethra,
Told under ripple, tip position also is difficult to determine, it is impossible to accurately injected in diseased region, lacks in security and quality
Ensure.In addition, its outside of existing urethra puncture needle is also provided with one layer of conduit, but these conduits are easily slided in urethra
It is dynamic, it is impossible to positioning well.
Utility model content
The purpose of this utility model is to provide a kind of urethral puncture injection needle simple in construction, easy to use, to solve
The problem of being proposed in above-mentioned background technology.
To achieve the above object, the utility model provides following technical scheme：
A kind of urethral puncture injection needle, including overcoat conduit, syringe needle, blown jacket, needle stand, handle and the 3rd sleeve pipe, institute
State to be provided with cavity, cavity in overcoat conduit and be provided with linear syringe needle, the tail end of syringe needle is connected with the pin coordinated with syringe
Seat, needle point of the left end provided with syringe needle of overcoat conduit is exported, and scale is provided with along catheter body direction on overcoat conduit, overcoat conduit
Right-hand member is connected with handle, and the overall length of overcoat conduit and handle is shorter than the length of syringe needle, and the 3rd set is provided between handle and needle stand
Pipe, axis direction of the 3rd sleeve pipe along syringe needle is provided with open slot；One layer of blown jacket is additionally provided with the outside of the overcoat conduit, is filled
The left end of gas bushing is provided with fixation balloon, and the inside of blown jacket is provided with filling channel, and filling channel is connected with fixation balloon.
Further：The bottom right side of the blown jacket is provided with inflation connecting tube.
Further：The width of the open slot is more than the diameter of syringe needle.
Compared with prior art, it is of the present utility model simple in construction, easy to use, blown jacket, the fixation balloon of setting
Overcoat conduit is enabled to be positioned in urethra, so as to prevent overcoat catheter displacement from causing positioning inaccurate, so as to be worn
Thorn is made troubles.
Brief description of the drawings
Fig. 1 is a kind of structural representation of urethral puncture injection needle.
Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Referring to Fig. 1, a kind of urethral puncture injection needle, including overcoat conduit 2, syringe needle 1, blown jacket 4, needle stand 9, handle
5 and the 3rd sleeve pipe 7, it is provided with cavity 11, cavity 11 in the overcoat conduit 2 and is provided with linear syringe needle 1, the tail end of syringe needle 1
The needle stand 9 coordinated with syringe is connected with, needle point of the left end provided with syringe needle 1 of overcoat conduit 2 is exported, and edge is led on overcoat conduit 2
Body direction is provided with scale, and the right-hand member of overcoat conduit 2 is connected with handle 5, and the overall length of overcoat conduit 2 and handle 5 is longer than syringe needle 1
Degree is short, and the 3rd sleeve pipe 7 is provided between handle 5 and needle stand 9, and axis direction of the 3rd sleeve pipe 7 along syringe needle 1 is provided with open slot 8, opened
The width of mouth groove 8 is more than the diameter of syringe needle, consequently facilitating the 3rd sleeve pipe 7 departs from from syringe needle 1；The outside of the overcoat conduit 2
One layer of blown jacket 4 is additionally provided with, the left end of blown jacket 4 is provided with fixation balloon 3, and the inside of blown jacket 4 is provided with filling channel
10, filling channel 10 is connected with fixation balloon 3, and the bottom right side of blown jacket 4 is connected provided with inflation connecting tube 6 by inflating
Pipe 6 can just think inflation in fixation balloon 3；In use, be first connected needle stand 9 with equipped with the syringe of decoction, the is then penetrated
Three sleeve pipes 7 and overcoat conduit 2, then insert urethra by overcoat conduit 2 and syringe needle 1, when overcoat conduit 2 is after being inserted into position, pass through
Inflation connecting tube 6 thinks that fixation balloon 3 is inflated, so that overcoat conduit 2 is positioned in urethra, overcoat conduit 2 is placed on syringe needle 1
On, it is to avoid damage urethra, while syringe needle 1 adds the hardness of overcoat conduit 2, it is easy to urethra to insert；Thereafter the 3rd sleeve pipe is taken down again
7, injection needle needle stand 9 is pushed into forward at handle 5, syringe needle 1 is passed from the needle point outlet of overcoat conduit 2, just can be direct
Injected.
The better embodiment to this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
, can also be on the premise of this patent objective not be departed from formula, the knowledge that one skilled in the relevant art possesses
Various changes can be made.
