Description

Technical Field

[0001] The invention relates to a curettage device and a use method thereof, in particular to a curettage device and a use method thereof for obstetrics and gynecology. Background Art

[0002] Curettage is scraping the uterus, also known as curettage. Curettage is the traditional artificial abortion. Curettage is different from abortion. It is used to remove the tissues in the uterine cavity after incomplete abortion, help repair the uterus, and reduce the possibility of bleeding or infection. Curettage is the most commonly used method for early artificial abortion. Although curettage does not require surgery, it is also a gynecological operation and must be performed under strict disinfection. The operation is divided into two steps. The first step is to dilate the cervix to a sufficient size, and the second step is to use a curette to extend into the uterine cavity and scrape out the embryo. Therefore, the curettage device used in obstetrics and gynecology is an important medical device. In the existing curettage devices used in obstetrics and gynecology, the cervical dilator is connected to the external support frame, and then the curette is connected to the cervical dilator. Since the cervical dilator is directly supported by a rod, the risk of injury to the patient is increased. The present invention has the technical feature of setting a detachment motion trajectory during the detachment of the embryo, and has conducted effective exploration and research on the technical problem of connecting the cervical dilator to the external support frame and then connecting the curette to the cervical dilator at the technical level.

The method for using the curettage device for obstetrics and gynecology according to claim 9, characterized in that the steps are: When it is necessary to perform curettage on the patient, the first clamping nut (8) is rotated in the rod IV (62), the receiving hole body VII (73) of the first cervical dilator (7) is placed on the rod IV (62) and the rod V (63), and then the second clamping nut (8) is rotated in the rod IV (62), the third clamping nut (8) is rotated in the rod IV (62), the receiving hole body VII (73) of the second cervical dilator (7) is placed on the rod IV (62) and the rod V (63), and then the fourth clamping nut (8) is rotated in the rod IV (62), so that the transverse plate portion (72) of the first cervical dilator (7) and the transverse plate portion (72) of the second cervical dilator (7) are placed on the rod IV (62) and the rod V (63). The first cervical dilator (7) and the second cervical dilator (7) are moved on the part V (63), so that the vertical plate part (71) of the first cervical dilator (7) and the vertical plate part (71) of the second cervical dilator (7) are in a closed state, the patient lies on the operating table, the support seat (90) is placed on the side of the operating table, the control motor located on the lateral movement screw (3) is in a working state, the lateral movement screw (3) is rotated in another through hole body and the threaded hole body I (23) of the support seat (90), the beam part I (21) is moved in one of the through holes of the support seat (90), and the shaft part (22) is moved in the receiving hole body IV (24), the control motor located on the vertical movement screw (5) is in a working state, and the vertical movement screw (5) is rotated in the receiving hole body V (25) and the threaded hole body The accommodating groove (42) is rotated in the accommodating hole (26), so that the two cervical dilators (7) in the closed state are placed in the cervix, and the control motor located on the transverse moving screw (3) and the control motor located on the vertical moving screw (5) are in a non-working state, so that the transverse plate portion (72) of the first cervical dilator (7) and the transverse plate portion (72) of the second cervical dilator (7) move in opposite directions on the rod portion IV (62) and the rod portion V (63), so that the vertical plate portion (71) of the first cervical dilator (7) and the vertical plate portion (71) of the second cervical dilator (7) are in an expanded state, so that the first clamping nut (8), the second clamping nut (8) and the third clamping nut (8) are in an expanded state. The nut (8) and the fourth clamping nut (8) rotate in the rod IV (62), so that the inner end surface of the first clamping nut (8) and the inner end surface of the second clamping nut (8) act on the horizontal plate (72) of the first cervical dilator (7) respectively, and the inner end surface of the third clamping nut (8) and the inner end surface of the fourth clamping nut (8) act on the horizontal plate (72) of the second cervical dilator (7) respectively, so that the cervix is ​​in an expanded state. The operator holds the rod I (11) in his hand, passes the scraper (1) between the vertical plate (71) of the first cervical dilator (7) and the vertical plate (71) of the second cervical dilator (7), and puts the strip II (13) on one side of the embryo in the uterine cavity.The receiving hole body III (18) is installed on the rectangular outer end of the rod part VIII (931), and the operator's hand is separated from the rod part I (11). The operator holds the rod part X (934) and rotates the rod part VIII (931) and the rod part IX (933) in the receiving hole body X (912) to adjust the positive direction tilt angle of the rod part I (11). When the positive direction tilt angle of the rod part I (11) is between 40 and 44 degrees, the operator separates from the rod part X (934) and rotates the lifting screw (92) in the threaded hole body III (95) and the receiving hole body XI (913) to move the seat part III (911) downward on the frame part (98) to adjust the rod part II (14 ) moves in the receiving hole body I (16), so that the rod part III (15) moves in the receiving hole body II (17), so that the strip part II (13) is in a deformed state, and the seat part II (99) moves on the rod parts VI (64) and the rod parts VII (65), and the strip part II (13) separates the embryo from the uterine cavity, and one of the side surfaces of the rod part III (15) supports the separated embryo. When the strip part II (13) is located on the other side of the embryo in the uterine cavity, the rod parts VIII (931) and the rod parts IX (933) are rotated in the opposite direction in the receiving hole body X (912), and the reverse tilt angle of the rod part I (11) is adjusted, so that the reverse tilt angle of the rod part I (11) is The angle of the seat II (99) is 20-24°, the seat II (99) moves in the opposite direction on the rod VI (64) and the rod VII (65), the embryo is separated from the uterine cavity again by the strip II (13), and the embryo is supported by the other side of the rod III (15), the lifting screw (92) rotates in the opposite direction in the threaded hole body III (95) and the receiving hole body XI (913), the seat III (911) moves upward on the frame (98), the strip II (13) is in the initial state, the receiving hole body III (18) is separated from the rectangular outer end of the rod VIII (931), and the scraper (1) is removed from the vertical plate portion (71) of the first cervical dilator (7) and the second cervical dilator (7). The first cervical dilator (7) is taken out from between the vertical plate portion (71) of the dilator (7), so that the inner end surface of the first clamping nut (8) and the inner end surface of the second clamping nut (8) are separated from the horizontal plate portion (72) of the first cervical dilator (7), and the inner end surface of the third clamping nut (8) and the inner end surface of the fourth clamping nut (8) are separated from the horizontal plate portion (72) of the second cervical dilator (7), so that the vertical plate portion (71) of the first cervical dilator (7) and the vertical plate portion (71) of the second cervical dilator (7) are in an expanded state, and the control motor located on the vertical moving screw (5) is in an operating state, and the two cervical dilators (7) in the closed state are taken out from the cervix.
