[0002] Hysteroscopic surgery is a new, minimally invasive gynecological diagnosis and treatment technology, a fiber-light endoscope used for intrauterine examination and treatment. Hysteroscopy has a magnifying effect on the observed area, and can intuitively, accurately and clearly observe intrauterine diseases for diagnosis and treatment. It is the gold standard for diagnosing intrauterine lesions and the preferred examination method for gynecological hemorrhagic diseases and intrauterine lesions, especially submucosal uterine fibroids, which are popular among doctors and patients because of their small trauma, less bleeding, less pain, and fast recovery. How to collect specimens simply and effectively during surgery has always been a problem that troubles gynecologists. The traditional practice is to use sterile gauze to collect specimens. This practice has two disadvantages. The first is that it affects the surgical field, and the second is that part of the specimen flows away with the uterine distention fluid, making it difficult to collect. For submucosal uterine fibroid surgery, such as frequent tissue collection, prolonged operation time, and the need for assistants to cooperate, increasing labor costs.

[0003] Therefore, it is necessary to design a disposable hysteroscopic electroresection specimen collector. Utility Model Content

[0024] During hysteroscopic electrosurgical resection, when it is necessary to collect the removed tissue specimens, the specimen collector is needed. The following operation is the specific use of the specimen collector. During hysteroscopic surgery, the disposable hysteroscopic electrosurgical specimen collector is inserted from under the handle of the speculum. According to the setting of the lead wire 2, the specimen collection bag 1 can be opened for subsequent collection work. According to the setting of the medical non-woven fabric 9 with medical pressure-sensitive adhesive and the anti-adhesion paper 10, the anti-adhesion paper 10 is firstly put into the hysteroscopic electrosurgical resection. 0 is torn open, and then the medical non-woven fabric 9 with medical pressure-sensitive adhesive is attached to the two thighs of the patient to fix the specimen collection bag 1, and at the same time, the specimen collection bag 1 can be limited to the bottom of the handle of the speculum. Then, the tissue removal operation of the hysteroscopic electroresection operation can be performed, and the removed tissue and the generated uterine distension fluid can be collected by the specimen collection bag 1, and the filter screen 4 in the specimen collection bag 1 is made of coarse mesh material, which can meet the mesh size of the uterine distension fluid and diluted blood can pass through the mesh, but the tissue will be intercepted by the filter screen 4, so that the collected tissue specimens remain in the specimen collection bag 1, and the uterine distension fluid will flow along the fine mesh holes in the filter screen 4 and the fine mesh 5, and the small specimens will be intercepted by the fine mesh 5, so that the secondary collection of the specimens can be realized, and the tissue specimens can be better classified and collected. At the same time, the field of view during hysteroscopic electroresection can be guaranteed to be clear, which is convenient for surgical operation. When the specimen needs to be taken out, the medical non-woven fabric 9 with the medical pressure-sensitive adhesive can be torn off from the inner thigh of the patient, so that the disposable hysteroscopic resectoscope specimen collector is not fixed, and then the disposable hysteroscopic resectoscope specimen collector is taken out from under the handle of the speculum. The disposable hysteroscopic resectoscope specimen collector is mainly divided into two parts: a specimen collection bag 1 and a fine net 5, and these two parts can be separated. During the specific operation, the limiting ring 8 embedded in the clamping ring 6 is pulled out, and the fine net 5 is separated from the specimen collection bag 1. At this time, the tissue specimens can be taken out and preserved using the formalin immersion method. The disposable hysteroscope resectoscope specimen collector is a disposable sterile product. When collecting specimens, it can avoid the specimens from being contaminated. After use, the disposable hysteroscope resectoscope specimen collector can be directly discarded as medical waste, thereby reducing medical costs, alleviating the economic burden on patients, and reducing medical waste. At the same time, when collecting specimens, no matter how much or how little, specimens can be obtained for clinical treatment. When performing submucosal uterine fibroid surgery, the disposable hysteroscope resectoscope specimen collector does not require frequent supervision by medical staff, and during surgery, no assistant is required to cooperate in taking specimens.
