A hysteroscopic endometrial injection needle

Abstract

The invention discloses a hysteroscope endometrium injection needle which comprises a needle head, a bent section, a needle body and a pull rope. The needle head is provided with scales, the bent section is arranged between the needle head and the needle body, the joint of the needle head and the bent section is provided with a fixing hole; and the joint of the needle body and the bent section is provided with a guide hole. One end of the pull rope is fixed into the fixing hole, the free end of the pull rope penetrates the guide hole to extend to the tail end of the needle body along the needle body, and the tail end of the needle body is provided with a medicine feeding port. The injection needle can perform injection on different positions of the uterus, and the injection depth is visible. By pulling or loosening of the pull rope, the bending degree of the bent section can be controlled, so that the direction of the needle head is adjusted to perform omni-directional injection. The scales on the needle head are observed through a hysteroscope, so that the injection depth can be controlled more accurately.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a hysteroscopic endometrial injection needle. Background technique [0002] Severe damage to the endometrium results in destruction of the vascular network in the basal layer of the endometrium, a large loss of uterine tissue stem cells, scarring of the endometrium, intrauterine adhesions, secondary amenorrhea, and uterine infertility. There is currently no effective treatment for this . Animal experiments have shown that rapid vascularization and cellularization of the scar can promote the functional repair of the endometrium. Clinically, the localization of endometrial scars depends on hysteroscopic observation, and the injection of some specific cytokines or enzymes into the scar site through hysteroscopy is expected to improve endometrial scarring. However, existing injection needles cannot inject into the anterior, posterior, and side walls of the uterus through ...
