Description

Technical Field

[0001] The present invention relates to the technical field of gynecological medicine, and in particular to a minimally invasive gynecological tissue sampling device. Background Art

[0002] In the field of gynecological medicine, minimally invasive tissue sampling technology has become an important means of diagnosing and treating a variety of gynecological diseases. Obtaining tissue samples through minimally invasive methods can not only reduce the patient's physical trauma, but also improve the accuracy and timeliness of diagnosis. However, existing minimally invasive gynecological tissue sampling devices have some significant shortcomings in practical applications, especially in terms of single sampling methods and lack of diversified tissue sampling capabilities. These problems not only limit their scope of application, but may also affect the reliability of diagnostic results.

[0003] Existing minimally invasive gynecological tissue sampling devices usually use a relatively single sampling method, which makes it difficult for doctors to choose the most appropriate sampling tool when faced with different types of diseased tissues. For example, some devices are only suitable for obtaining surface tissue samples, but are incapable of lesions in deep or special locations (such as the cervical canal and under the endometrium). This limitation causes doctors to rely on traditional laparotomy or other more invasive methods to obtain more comprehensive pathological information in actual operations, increasing patients' pain and surgical risks. In addition, a single sampling method may also miss important lesion areas, affecting the final diagnosis results.

[0004] Existing devices have failed to fully consider the characteristics of different types of tissues in their design and cannot meet diverse sampling needs. Different gynecological diseases involve different types of tissues, such as benign tumors, malignant tumors, inflammation, etc. The texture, density and structure of each diseased tissue are different. Therefore, different techniques and tools are needed during the sampling process to ensure the quality and representativeness of the samples. However, most of the current minimally invasive sampling devices lack flexibility and cannot be adjusted according to specific circumstances. For example, for harder fibrotic tissue or softer cystic tissue, existing devices often have difficulty in providing sufficient cutting force or suction, resulting in sampling failure or poor sample quality. This situation not only affects the accuracy of pathological analysis, but may also lead to misdiagnosis or missed diagnosis, delaying the best time for treatment.

[0005] Existing minimally invasive gynecological tissue sampling devices also have shortcomings in terms of ease of operation and adaptability. In order to achieve minimally invasive sampling, doctors need to operate through a small puncture channel, which places higher requirements on the design of the equipment. If the sampling tool is too complicated or large in size, it will be difficult to enter the target area smoothly, increasing the difficulty of operation and technical requirements. At the same time, the fixed operation mode also limits the doctor's ability to flexibly adjust the sampling angle and depth according to actual conditions, reducing the efficiency of the operation. In addition, some devices also require additional auxiliary equipment or steps to complete the sampling process, further prolonging the operation time and increasing the patient's discomfort and psychological burden.
