[0004] The traditional hysterectomy resectoscope has the following disadvantages: First, the positions of the electrode tip and the resectoscope are relatively fixed. If it is necessary to adjust the position of the electrode tip during operation, it needs to be connected with the entire resectoscope and its connecting device (illumination guide). Beam and camera) rotate together, it is easy to interfere with the operating doctor's sense of direction, and it takes a long time for the operating doctor to adapt, which is very inconvenient; second, the position of the electrode tip and the resectoscope is relatively fixed, so the observation angle is fixed, The electrode rod will block the surgical field of view, and the operator cannot fully see the cut site, which poses operational hazards and surgical risks

Abstract
The invention discloses a hysterectomy resectoscope. The hysterectomy resectoscope includes an electric cutter; a mirror body, the mirror body has a working channel for being installed on the electric cutter; the head end of the mirror body is equipped with a lens and a light unit, The lens tilts toward the direction of the working channel at a preset angle; wherein, the electric cutting knife includes: electric cutting ring; electric cutting rod, the electric cutting ring is connected to the electric cutting rod; there is a preset clip between the electric cutting ring and the electric cutting rod Angle, the range of the preset included angle is an acute angle; wherein the electric cutting rod includes a first extension rod, a second extension rod and a base rod, the first extension rod and the second extension rod are respectively connected to the base rod, and the two ends of the electric cutting ring Installed on the ends of the first extension rod and the second extension rod away from the base rod respectively, wherein the preset position of the rear end of the base rod has a first card slot, and the preset position of the mirror body has a first locking member; during operation Among them, the head end of the electric resectoscope can be located in the center of the field of view of the lens, which is convenient for operation; the electric resectoscope can rotate relative to the mirror body, which is convenient for operation.
Description
technical field [0001] The invention relates to the field of hysterectomy resectoscope, and further relates to the hysterectomy resectoscope. Background technique [0002] Hysterotomy is a new, minimally invasive gynecological diagnosis and treatment technology. It is a light source endoscope used for intrauterine examination and treatment. It has a magnifying effect, and with the advantages of intuition and accuracy, it has become the first choice of inspection equipment for gynecological bleeding diseases and intrauterine lesions. [0003] Electrode heads used in traditional hysterectomy resectoscopes include ring electrodes, needle electrodes, rolling electrodes, and spherical electrodes. On the endoscope, the electrode tip is coaxial with the endoscope body. Therefore, in the working state, there is a definite locking relationship between the electrode structure of the entire endoscope and the endoscope, and the relative positions of the electrode tip and the resectosc...
