Description

Portable flexible hysteroscope

Technical Field

The utility model belongs to the technical field of medical instrument, specifically indicate a portable flexible hysteroscope.

Background

The hysteroscope is an endoscope which is commonly used for the examination and treatment in the uterine cavity of the gynecology department and mainly comprises the hysteroscope, an energy system, a light source system, a perfusion system and an imaging system. When the endoscope is used, the front part of the endoscope body enters the uterine cavity, and the part needing to be observed is subjected to amplification real-time imaging, so that a simple and effective detection method is provided for diagnosing gynecological hemorrhagic diseases and intrauterine pathological changes.

At present, the hysteroscope which is most widely used clinically is a hard hysteroscope, and when the hysteroscope is used, a patient needs to be anesthetized firstly, then a special cervical dilator is adopted to dilate the cervix under the anesthesia state of the patient, and finally, a uterine cavity lens can be inserted into the uterine cavity for observation. The whole operation process is quite complicated, and has high requirements on the physical state of a patient and the professional skill of a doctor. Most importantly, the hard hysteroscope inevitably causes uncomfortable symptoms such as pain and bleeding after operation, and even some patients need to lie in bed for rest. The main reason for the problems is that the whole hysteroscope is made of hard metal materials and is not friendly to the uterine cavity environment; still another reason is that the hysteroscope is not small enough in size and inevitably causes friction when passing through the cervical orifice. The Endosee hysteroscope series developed by Cooper Surgical company at present solves part of the problems and realizes the detection under the condition of outpatient service without anesthesia. However, the series of products still cause pain and bleeding during use, and the main reasons are two: firstly, compared with a hard hysteroscope, the product has the advantages that the appearance of the product is increased by a soft material to coat the detection scope body part, but the interior of the hysteroscope is still a metal hard tube cavity, the design can only weaken the endometrial injury caused by contact when part of the hard hysteroscope is inserted for detection, and the integral rigid design has a friendly degree to the soft tissue environment of the endometrium which needs to be improved; secondly, the diameter of the detection lens of the Endosee series products is 4.3mm, and the size is slightly larger than the average size of the cervical orifice by 4mm, so that when the detection is carried out under the conditions of no anesthesia and no cervical dilatation, the cervical orifice is inevitably stimulated to cause the problems of pain, bleeding and the like.
