Description
Technical field
This utility model is related to medical instruments field, and in particular to a kind of endoscope-use injection needle.
Background technology
Endoscope-use injection needle is used in splanchnoscopy to intravascular injection sclerosing agent or tissue glue, to control Digestive
Bleeding that is that system has occurred or may occurring.The injection needle for using at present include one for injection handle, pipe sheath, inner tube
And it is fixed on the syringe needle of interior tube head, the needle point of syringe needle mostly is 0.4-0.5cm length, unlimited bit architecture between inner tube and pipe sheath,
The length of needle point cannot be controlled, cannot also limit the relative rotation between inner tube and pipe sheath, easily affect operation accurate
Property and operation safety.
Utility model content
For solving the above problems, this utility model provides a kind of endoscope-use injection needle, and which can carry out double to inner tube
To spacing, it is ensured that the safety of the accuracy of operation and operation process.
Technical solutions of the utility model are as follows：
This utility model includes the inner tube that handle is fixedly connected with the handle front end, is fixed on said inner tube head
Syringe needle and the pipe sheath being socketed on outside said inner tube；
This utility model also includes that being arranged at the pipe sheath front end stretches out length for observing the syringe needle from the pipe sheath
The rule of degree and for carrying out axially and radially bidirectionally limited bidirectionally limited device to said inner tube.
The bidirectionally limited device includes being symmetricly set in two spacing preiections of said inner tube two sides of tail, is opened in institute
State the axial limiting groove of corresponding position on pipe sheath and the more than one footpath being opened in the axial limiting groove vertically
To stopper slot；Height of the axial limiting groove depth less than the spacing preiection；The spacing preiection and/or pipe sheath have one
Fixed elasticity.The one end of said inner tube at handle is afterbody, is head away from the one end at handle；Said inner tube stretch out one
Hold the front end for pipe sheath；The width ratio spacing preiection width of the axial limiting groove is big, both can ensure that spacing preiection vertically
Stopper slot length direction slides, and can ensure that spacing preiection will not be rotated again.
Used as further improvement of the utility model, the spacing preiection is the spacing preiection with smooth surface, not only
Can be stuck in radial direction stopper slot, it is also possible to by advance and retreat of the force controlled spacing preiection in radial direction stopper slot.
Used as further improvement of the utility model, the spacing preiection is hemispherical spacing preiection.
Used as further improvement of the utility model, the radial direction stopper slot is equidistantly arrangement.
Used as further improvement of the utility model, the radial direction stopper slot quantity is three.
Used as further improvement of the utility model, the spacing of each radial direction stopper slot is 1.5mm.
This utility model has the following technical effect that：
（1）The extension elongation of syringe needle can be carried out essence by arranging bidirectionally limited device and rule by this utility model
It is determined that while position, carrying out axial limiting to inner tube and radial direction being spacing, limit inner tube with pipe sheath in relative fortune axially and radially
It is dynamic, increase operation degree of accuracy, reduce operation risk.
（2）This utility model pipe sheath front end is provided with rule, coordinates with bidirectionally limited device, before injection first by pipe sheath and
Vein diameter is compared, and can be estimated out needs and be stretched out injection needle how long, so that it is determined which radial direction spacing preiection is limited to
Stopper slot, increased operation precision.
（3）Spacing preiection and axial limiting groove are set, the moving direction of inner tube is limited in the axial direction, inner tube and pipe is prevented
Sheath relatively rotates.
（4）The position of inner tube is fixed by this utility model by arranging spacing preiection and radial direction stopper slot, it is to avoid empty
Stroke phenomenon, while preventing inner tube from stretching out from pipe sheath excessively, punctures blood vessel, reduces operation risk.
（5）This utility model spacing preiection is hemispherical spacing preiection, and spacing preiection has smooth surface, not only can block
In radial direction stopper slot, it is also possible to by advance and retreat of the force controlled spacing preiection in radial direction stopper slot, prevent spacing preiection quilt
It is stuck in radial direction stopper slot.
（6）Length of needlepoint is generally 0.4-0.5cm, arranges three radial direction stopper slots, each spacing separation of radial direction
1.5mm, it is to avoid because radial direction stopper slot quantity excessively causes complex structure, it also avoid because of the very few impact of radial direction stopper slot quantity
Feed accuracy.
Description of the drawings
Accompanying drawing 1 is this utility model structural representation.
In accompanying drawing：1- pipe sheaths；2- inner tubes；3- spacing preiections；4- axial limiting grooves；5- radial direction stopper slots；6- rules；7-
Syringe needle.
Specific embodiment
The technical solution of the utility model is described in further detail below in conjunction with specific embodiment.
As shown in figure 1, this utility model include the inner tube 2 that handle is fixedly connected with the handle front end,
The syringe needle 7 for being fixed on 2 head of said inner tube and the pipe sheath 1 being socketed on outside said inner tube 2；
This utility model also includes that being arranged at 1 front end of pipe sheath stretches out from the pipe sheath 1 for observing the syringe needle 7
The rule 6 of length and for carrying out axially and radially bidirectionally limited bidirectionally limited device to said inner tube 2.By arranging
Bidirectionally limited device and rule 6, while can be accurately positioned the extension elongation of syringe needle 7, carry out axial direction to inner tube 2
It is spacing and radially spacing, inner tube 2 is limited with pipe sheath 1 in relative motion axially and radially, increase operation degree of accuracy, reduce operation
Risk.
The bidirectionally limited device includes being symmetricly set in two spacing preiections 3 of 2 two sides of tail of said inner tube, is opened in
The axial limiting groove 4 of corresponding position and three and institute being opened in the axial limiting groove 4 vertically on the pipe sheath 1
The radial direction stopper slot 5 that fiber protrusion 3 is engaged is stated, the radial direction stopper slot 5 is equidistantly arrangement, each described radial direction stopper slot
5 spacing is 1.5mm, it is to avoid because radial direction stopper slot 5 quantity excessively causes complex structure, be it also avoid because of radial direction stopper slot 5
The very few impact feed accuracy of quantity；The axial limiting groove 4 is preferably rectangular slot, and its depth is less than the spacing preiection 3
Highly；The spacing preiection 3 and/or pipe sheath 1 have certain elasticity.
This utility model is as follows using process：
First by pipe sheath 1 compared with human vein diameter, estimating out syringe needle needs the length of 1 front end of protruded tube sheath, is peeped by interior
Sem observation rule 6, then calculating spacing preiection 3 needs to shift onto in which radial direction stopper slot 5, is forcibly driven by hand
Or in the radial direction stopper slot 5 for extracting required for spacing preiection 3 is adjusted to, spacing preiection 3 two radial direction stopper slots 5 it
Between when, limited by axial limiting groove 4, prevent which from relatively rotating with pipe sheath 1.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or use that this practicality is new
Type.Various modifications to these embodiments will be apparent for those skilled in the art, determined herein
The General Principle of justice can be realized in the case of without departing from spirit or scope of the present utility model in other embodiments.Cause
This, this utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
