Description
Technical field
The present invention relates to technical field of medical equipment, particularly relate to a kind of hysteroscope endometrium entry needle.
Background technology
Endometrium major injury causes basal layer vasoganglion to destroy, uterine cancer cell stem cell is lost in a large number,
Endometrium scarring, intrauterine adhesion, secondary amenorrhea, uterine infertile etc., to this effective Therapeutic Method of current shortage.Dynamic
Thing experimentation shows, makes the quick vascularization in cicatrix position, cellularised can promote the functional reparation of endometrium.Clinically, son
Endometrium cicatrix location depends on hysteroscope and observes, and is guided by hysteroscope and some specific cells factors or enzyme are injected at cicatrix
Position, is expected to improve inner membrance scarring.But, existing injection needle exists cannot be through cervix uteri, side forward and backward to uterus in uterine cavity
Wall is injected, simultaneously the most uncontrollable defect of injection depth, crosses and deeply can cause the perforation of uterus, and the most shallow cannot ensure medicine
In injection Endometrium, simply it is injected in intimal surface and uterine cavity.The most both waste somatomedin and also cannot remove scarring
Inner membrance on be formed with the environment of beneficially stem cell growth, be unfavorable for the expansion of follow-up work.
The utility model patent of the patent No. " 201420325844.9 " " intrauterine injection syringe needle " proposes the problems referred to above, and carries
Having gone out the solution of " shank and syringe needle are approximate right angle shape ", the length bent by syringe needle controls liquid medicine injection at Uterus wall
The degree of depth of (inner membrance and muscle layer joint), by rotating syringe metering needle head direction, injects the diverse location in uterus.?
Actual when carrying out uterus drug injection, it is monitored often through hysteroscope；That performs the operation for convenience is smoothed out, it will usually to
Uterus is injected swollen palace liquid.And this patented technology controls deep at Uterus wall of liquid medicine injection by the length arranging syringe needle bending
Degree, therefore the length of syringe needle bending will not be oversize, owing to uterus is the most expanded, by rotating syringe metering needle head direction, to uterus
The diverse location scheme that carries out injecting obviously can not realize.
The utility model patent of the patent No. " 201520425487.8 " " endometrium cicatrix puncture injection needle " proposes note
Penetrate the uncontrollable problem of the degree of depth, and propose solution: by protection set sheathed on needle handle, being shorter in length than of protection set
The length of needle handle, bending syringe needle can be accommodated when sliding to needle handle front end in the toggle inner chamber of protection set by protection set, protection set to
Time slip in needle handle rear end, bending syringe needle exposes；It is provided with scale on needle handle, solves the uncontrollable problem of injection depth, but
Its problem the most not solving uterus diverse location is injected.
Summary of the invention
The present invention is directed to that uterus diverse location can not be injected by existing entry needle, injection depth is uncontrollable asks
Topic, develops a kind of hysteroscope endometrium entry needle, and uterus diverse location can be injected by this entry needle, and injection depth can
Depending on, convenient control.
The present invention solves the technical scheme of technical problem: a kind of hysteroscope endometrium entry needle, including syringe needle, bending
Section, needle body, stay cord, syringe needle is provided with scale, and bending section is arranged between syringe needle and needle body, syringe needle and the junction of bending section
Being provided with fixing hole, needle body is provided with pilot hole with the junction of bending section, and one end of stay cord is fixed in fixing hole, stay cord
Free end extends to needle body end through pilot hole along needle body, and needle body end is provided with drug delivery port.
As optimization, the pliability of described bending section is more than the pliability of needle body.
As optimization, described needle body being provided with wire casing, stay cord passes wire casing.
As optimization, the scale on described syringe needle is complete annular.
As optimization, the free end of described stay cord is provided with draw ring.
As optimization, the free end of described stay cord connects controller, and controller is gear reduction unit, and stay cord free end is fixed
On gear reduction unit output shaft.
As optimization, the lower section of described needle body end drug delivery port is provided with rotation wheel.
As optimization, the surface configuration of described rotation wheel is fluted.
As optimization, described rotation wheel is high-abrasive material.
Beneficial effects of the present invention:
1. uterus diverse location can be injected by the entry needle of the present invention, and injection depth is visual.By drawing, pine stay cord can
Realize the control to bending section degree of crook, thus adjust the direction of syringe needle, it is achieved that comprehensive injection.Observed by hysteroscope
Scale on syringe needle, can control the degree of depth of injection more accurately.
2. the pliability due to bending section is more than the pliability of needle body.Ensured draw, pine stay cord time, bending section bending, pin
Body is indeformable.
3., by being provided with wire casing on needle body, stay cord passes wire casing.Stay cord is arranged in wire casing, on the one hand avoids
The stay cord pollution to surgical environments, on the other hand, owing to stay cord and needle body are the intensity that laminating and wire casing add needle body,
Ensured draw, pine stay cord time, bending section bending, needle body indeformable..
4. it is complete annular due to the scale on syringe needle.Such that regardless of syringe needle in which direction, what angle, Dou Nengtong
Cross hysteroscope and observe the scale on syringe needle.
5. connecting controller by the free end at stay cord, controller is gear reduction unit, and stay cord free end is fixed on tooth
On wheel decelerator output shaft.The control to stay cord can be realized by the control axle of swing pinion decelerator, make control by decelerator
System is more accurate, improves the precision of operation.
6. by arranging rotation wheel in the lower section of needle body end drug delivery port.By rotate wheel can rotary injection pin easily,
Realize the adjustment in syringe needle orientation；The adjustment of needle position is realized by the position of integrated regulation entry needle；By drawing, pine stay cord real
The adjustment of existing syringe needle angle.
7. by the surface configuration groove rotating wheel.Facilitate the rotation rotating wheel.
