Description
Technical Field
The invention relates to the technical field of hysteroscopic surgical devices, in particular to a hysteroscopic tissue excision device.
Background
Hysteroscopy generally refers to hysteroscopy, and is a novel minimally invasive gynecological diagnosis and treatment technology. Hysteroscopy is examination for examining the condition of the uterine cavity of a patient by using a hysteroscope, and directly observing physiological and pathological changes of a cervical canal, an endocervical opening, an endometrial cavity and an oviduct opening by using an optical fiber glass speculum inserted into the uterine cavity, and also taking pathological tissues for examination and pathological analysis; and can also be directly used for treatment under hysteroscopy.
Generally, for the excision of the pathological tissue or the proliferation tissue in the uterine cavity of a patient, the excision device is matched with a hysteroscope except for the necessary excision device, the pathological tissue or the proliferation tissue in the uterine cavity is fed back to an external display screen through a live picture through the hysteroscope, and a doctor can operate the excision device according to the live picture to excision the pathological tissue or the proliferation tissue.
The existing hysteroscope tissue cutting device generally adopts an annular blade type cutting mechanism, firstly utilizes suction action of an air suction pipe to adsorb pathological change or proliferation tissues and then performs circular cutting, but the blade cutting mode has certain defects when going deep into a patient body to cut tissues, as follows:
The pathological change or hyperplasia tissue condition in the uterine cavity of the patient is not single unchanged, but there are several conditions, some bulges are on the uterine wall, the root and uterine wall connecting area is very large, because the annular cutter incision is large, there is the possibility that the pathological change or hyperplasia tissue root system remains when the pathological change or hyperplasia tissue is resected, meanwhile, there is also pathological change or hyperplasia tissue sunken on the uterine wall, the root of the bulge malignant tissue is lower than the plane of the uterine wall, the bulge malignant tissue is not connected with the uterine cavity through the very small root, but the large-range root system is connected with the uterine cavity wall, the tissue root system is difficult to be completely resected in actual use, and the risk that the pathological tissue remains exists (because the annular cutter is adopted, a purse net is also arranged outside the cutter, and the cutter blade has a certain thickness, so the blade cannot directly attach the pathological tissue root);
Secondly, according to common sense, soft matters such as meat need to be repeatedly rubbed to lift the cutting force, if the knife is vertically placed on the meat, the knife is difficult to cut only by pressing down or is difficult to cut only by moving the knife back and forth, but not pressing down, in a simple way, two kinds of force are needed to realize efficient and accurate cutting, one kind of force is pressure, the other kind of force is friction, when soft pathological or proliferative tissues of a human body in a uterine cavity are resected, only circular cutting friction force is adopted, but no pressure is adopted (the pressure is provided by moving a resection device by a doctor), the cutting effect is not ideal, and if the meat is cut, the meat is cut very efficiently, the incision is very smooth, but if the meat is cut very slowly, the incision is rough, and similarly, the problem of rough incision and the like can be caused by the fact that the pathological or proliferative tissues are resected not efficiently, so that the subsequent incision is slow to recover;
The exposed blade has the defect of damaging human body in a static state, especially when the blade goes deep into the uterine cavity of a patient to carry out micromanipulation, experience and capability of doctors are extremely tested, meanwhile, the traditional hysteroscope tissue excision device is provided with a simple blocking net only outside the annular cutter (since pathological tissues can be easily cut, the excised pathological tissues can also fall out of the blocking net), the pathological tissues in the uterine cavity can not be easily dropped in the excision process can not be effectively intercepted, and the excised pathological tissues also have the falling risk in the excision process when the excision device is taken out.
