Description

[Technical Field]

[0001] The present invention relates to a curette, and more particularly to a menstrual blood-derived endometrial cell collection device. [Background technology]

[0002] In the diagnosis and research of gynecological diseases, collecting endometrial cells from menstrual blood is an important process, and its efficiency and convenience directly affect clinical procedures and sample quality. However, conventional collection devices have significant drawbacks, including the following: Most curettes have fixed functional components, which require disassembly of multiple parts for replacement, making operation time-consuming and cumbersome. Furthermore, the curette extension length is difficult to adjust, making it difficult to accommodate differences in user operating habits and physiological structures. Furthermore, conventional devices have a complex and large overall structure and poor portability, limiting their practical use in field collection and mobile clinics. As a result, this creates inconvenience for both medical professionals and self-collectors. Therefore, there is a strong need for an improved collection device that allows for quick replacement of the curette's functional components, flexible adjustment of the extension length, and excellent portability. Summary of the Invention

[0003] The problem to be solved by the present invention is to overcome the drawbacks of the prior art and to provide an improved device for collecting endometrial cells from menstrual blood.

[0004] To solve the above problems, the present invention provides the following technical solution: The menstrual blood-derived endometrial cell collection device of the present invention comprises a central hand-held hollow tube and a curette function part. The central hand-held hollow tube has open ends in the longitudinal direction, and an inner limiting hollow tube is disposed inside the open ends, the outer wall of which contacts the inner wall of the central hand-held hollow tube. The stopper ring further includes an annular stopper ring body, and a plurality of elastic stopper plates are evenly arranged on the annular stopper ring body. One end of each elastic stopper plate is fixed to the annular stopper ring body, and the extension lines of the elastic stopper plates are close to each other. A rotating knob is attached to the end of the central hand-held hollow tube by a threaded connection. The rotating knob has an external threaded portion that threadably connects to the end of the central hand-held hollow tube. A tapered annular pressure ring is provided at the end of the external threaded portion, and the tapered annular pressure ring acts on the outside of the multiple elastic stopper plates. The hollow shaft of the curette function passes through the pivot knob and extends into the interior of the inner limiting hollow tube. Preferably, a friction groove is formed on the outermost edge of the swivel knob.

[0005] The advantage of this device is that the user can quickly change the curette function and adjust the length of the protrusion from the central hand-held hollow tube by operating the rotatable knob, which makes it highly practical and portable. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0007] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following description will clearly and completely explain the technical solutions included in the embodiments with reference to the drawings according to the embodiments of the present invention. As shown in the drawings, the apparatus for collecting menstrual blood-derived endometrial cells of the present invention comprises a central hand-held hollow tube body 1 and a curette function part 2. Both longitudinal ends of the central hand-held hollow tube 1 are open, and inside is an internally bounded hollow tube 3. The outer wall of the internally bounded hollow tube 3 is in contact with the inner wall of the central hand-held hollow tube 1, and its length is shorter than that of the central hand-held hollow tube 1. The internally bounded hollow tube 3 is located in the center of the central hand-held hollow tube 1, and the distances between both end faces and both end faces of the central hand-held hollow tube 1 are equal. Furthermore, an annular stopper ring body 4 is provided, and a plurality of elastic stopper plates 5 are evenly arranged on the annular stopper ring body 4. One end of each of the elastic stopper plates 5 is fixed to the annular stopper ring body 4, and their extension lines are close to each other. A turning knob 6 is attached to the end of the central hand-held hollow tube 1 by a screw connection. An external thread 7 is formed on the turning knob 6, and the external thread 7 is screwed to the end of the central hand-held hollow tube 1. A sloped annular pressure ring 8 is provided on the end of the external thread 7, and the sloped annular pressure ring 8 acts on the outside of the multiple elastic stopper plates 5 to press them. Both ends of the turning knob 6 are open. The hollow shaft of the curette function part 2 passes through a rotating knob 6 and extends into the interior of the inner limiting hollow tube body 3. The hollow shaft is positioned by a plurality of elastic stopper plates 5. The turning knob 6 has a friction groove formed on the outermost edge thereof. Although the present invention and its embodiments have been described above, the scope of protection of the present invention is not limited thereto.
