Technical Field
The invention relates to the technical field of medical equipment, in particular to a hysteroscope endometrial injection needle.
Background
Serious damage to endometrium results in damage to blood vessel network in the basement layer of endometrium, great loss of stem cells in uterine tissue, scarring of endometrium, intrauterine adhesion, secondary amenorrhea, infertility of uterus, etc. and thus no effective treatment method is available. Animal experiment research shows that the rapid vascularization and cellularization of scar part can promote functional repair of endometrium. Clinically, the localization of the scar of the endometrium depends on the observation of a hysteroscope, and the scar part is injected with some specific cell factors or enzymes under the guidance of the hysteroscope, so that the cicatrization of the endometrium is expected to be improved. However, the existing injection needle has the defects that the injection can not be carried out to the front, the back and the side walls of the uterus in the uterine cavity through the cervix, and the injection depth can not be controlled, the uterus is perforated due to too deep depth, and the medicine can not be ensured to be injected into the intrauterine membrane but is only injected on the surface of the endometrium and in the uterine cavity due to too shallow depth. Thus, growth factors are wasted, an environment which is favorable for stem cell growth cannot be formed on the scar-removed inner membrane, and the development of subsequent work is not facilitated.
The utility model patent of patent No. "201420325844.9" uterine cavity syringe needle "provides the above-mentioned problem to the solution of" the needle bar is approximately right angle form with the syringe needle "has been proposed, through the crooked length control of syringe needle injection liquid medicine in the degree of depth of uterus wall (endometrium and muscular layer department of meeting), adjusts the syringe needle direction through rotatory syringe needle, injects the different positions of uterus. When the uterus medicine is actually injected, the uterus medicine is often monitored through a hysteroscope; in order to facilitate the smooth operation, uterus expanding liquid is usually injected into the uterus. The technology of the patent controls the depth of the injection liquid medicine on the uterine wall by setting the bending length of the needle head, so the bending length of the needle head is not too long, and the scheme of injecting different positions of the uterus by rotating the needle cylinder to adjust the direction of the needle head because the uterus is already expanded can not be obviously realized.
The utility model patent of patent no "201520425487.8", "endometrial scar puncture needle" proposes the problem of the uncontrollable injection depth and proposes a solution: the needle handle is sleeved with the protective sleeve, the length of the protective sleeve is shorter than that of the needle handle, the bent needle head can be accommodated in the inner cavity of the sleeve handle of the protective sleeve when the protective sleeve slides to the front end of the needle handle, and the bent needle head is exposed when the protective sleeve slides to the rear end of the needle handle; the needle handle is provided with scales, so that the problem that the injection depth cannot be controlled is solved, but the problem of injecting different positions of the uterus is still not solved.

For a better understanding of the present invention, embodiments thereof are explained in detail below with reference to the accompanying drawings.
Fig. 1 to 4 show an embodiment of the invention, and as shown in the drawing, a hysteroscope endometrial injection needle comprises a needle head 1, a bending section 2, a needle body 3 and a pull rope 4, wherein scales are arranged on the needle head 1, the bending section 2 is arranged between the needle head 1 and the needle body 3, a fixing hole 101 is arranged at the joint of the needle head 1 and the bending section 2, a guide hole 304 is arranged at the joint of the needle body 3 and the bending section 2, one end of the pull rope 4 is fixed in the fixing hole 101, the free end of the pull rope 4 passes through the guide hole 304 and extends to the tail end of the needle body 3 along the needle body 3, and the tail end of the needle body 3 is provided with. The control of the bending degree of the bending section 2 can be realized by pulling and loosening the pull rope 4, so that the direction of the needle head 1 is adjusted, and the omnibearing injection is realized. The scale on the needle head 1 is observed through the hysteroscope, so that the injection depth can be controlled more accurately. The flexibility of the bending section 2 is larger than that of the needle body 3. When the pull rope 4 is pulled and loosened, the bending section 2 is bent, and the needle body 3 is not deformed. The needle body 3 is provided with a wire groove 303, and the pull rope 4 penetrates through the wire groove 303. Through setting up stay cord 4 in wire casing 303, avoided the pollution of stay cord 4 to the operation environment on the one hand, on the other hand, because stay cord 4 and needle body 3 are the laminating, and wire casing 303 has increased needle body 3's intensity, when having ensured drawing, loosening stay cord 4, crooked section 2 is crooked, needle body 3 is indeformable. The scale on the needle head 1 is in a complete ring shape. So that the scales on the needle head 1 can be observed through the hysteroscope no matter which direction and angle the needle head 1 is at. The free end of the pull rope 4 is provided with a pull ring 401. The control of the degree of bending of the bending section 2 can be achieved by pulling and releasing the pull ring 401. A rotating wheel 302 is arranged below the medicine feeding port 301 at the tail end of the needle body 3. The injection needle can be conveniently rotated through the rotating wheel 302, so that the direction of the needle head 1 can be adjusted; the position of the needle head 1 is adjusted by integrally adjusting the position of the injection needle; the angle of the needle head 1 is adjusted by pulling and loosening the pull rope 4. The surface of the rotator wheel 302 is provided with grooves. The provision of the recess facilitates rotation of the rotator wheel 302. The rotating wheel 302 is a wear resistant material. The use of wear resistant materials increases the life of the rotator wheel 302 and facilitates rotation of the rotator wheel 302.
As shown in fig. 3, when the injection needle is guided into the operation position, the pull rope 4 is firstly operated to reduce the radian of the bending section 2 to be capable of entering from the operation entrance; then the injection needle is guided into the operation position, and the position of the needle head 1 is adjusted by integrally adjusting the position of the injection needle according to the operation of actual conditions; the injection needle can be conveniently rotated through the rotating wheel 302, so that the direction of the needle head 1 can be adjusted; the angle of the needle head 1 is adjusted by pulling and loosening the pull rope 4.
