Description

Technical Field

[0001] The utility model relates to a medical device, in particular to a medical artificial abortion negative pressure suction tube. Background Art

[0002] The female uterus is located in the center of the pelvic cavity, with the bladder in front, the rectum in the back, and the vagina at the lower end. Due to the traction of the round ligament of the uterus and the uterosacral ligament, when the bladder is empty, the normal position of the adult uterus is slightly forward and flexed. If the patient has multiple uterine fibroids, adenomyosis, or after cesarean section, when the pregnancy state requires artificial abortion, the uterus is in an extremely forward or extremely backward position. At present, the negative pressure suction tube used for artificial abortion operation is a whole thin tube rod body, and the top of the thin tube rod body is a straight suction port, and the suction port and the inner diameter of the thin tube rod body are the same center. There is a round blunt head introduction body on the side of the top of the thin tube rod body, and the round blunt head introduction body is higher than the suction port. Due to the enlargement of the uterus in the pregnancy state, the suction device of the thin tube rod body cannot directly reach the position of the gestational sac in the uterine cavity. The suction tube needs to be adjusted to a certain angle before the operation can be performed, which leads to prolonged operation time, difficult operation, and repeated operation is prone to the risk of uterine perforation. The gestational sac is located at the uterine horns on both sides, biased towards the uterine cavity. No matter how the straight suction tube is adjusted, the suction port cannot reach the expected position of the gestational sac, resulting in the possibility of abortion failure. In addition, the common clinical models of negative pressure suction tubes are 6-8, and each model of negative pressure suction tube is an independent tube body for cervical depth selection. Therefore, during the operation, it is necessary to select and replace according to the cervical depth, resulting in a variety of instrument specifications. For this reason, it is necessary to improve and perfect the negative pressure suction tube. Summary of the invention

[0003] In view of the current status of the above-mentioned technology, the utility model provides a medical artificial abortion negative pressure suction tube, which can reach the gestational sac in the uterine horn and effectively avoid the risk of uterine perforation and the possibility of abortion failure.

[0004] The technical solution of the utility model is: a medical artificial abortion negative pressure suction tube, comprising two parts, an upper section and an lower section; wherein:

[0005] The upper section is a structure that transitions from a straight pipe section to a curved elbow. The curved elbow is provided with a suction hole that is eccentric to the inner diameter of the straight pipe section, and an upper connector is provided at one end of the straight pipe section.

[0006] The lower section is a straight pipe section, one end of which is provided with a lower connector, which is combined and connected into one piece with the upper connector of the upper section.

[0007] In the present invention, the upper connector of the upper section is provided with an inner countersunk hole with a variable diameter at one end of the straight pipe section, or an inner thread is provided on the inner countersunk hole.

[0008] In the present invention, the lower connector of the lower section is provided with a convex plug with a reduced diameter at one end of the straight pipe section, or the convex plug is provided with an external thread. In this way, the convex plug of the lower section or the external thread thereon is combined with the corresponding internal countersunk hole or internal thread of the upper section to form a whole.

[0009] In the present invention, the length specifications of the upper section are 8 cm, 9 cm, and 10 cm respectively.

[0010] In the present invention, the length specification of the lower section is 8 cm.

[0011] In the present invention, upper sections of different lengths can be replaced and combined with lower sections for use.

[0012] In the present invention, the suction hole is arranged at the belly position of the arc elbow of the upper section.

[0013] The combination model of the upper and lower sections of the present invention is No. 6-8, which is the same as the existing suction device model.

[0014] The beneficial effect of the utility model is that, by designing a combination of two parts, only one suction tube of the lower part can be used in combination with upper parts of multiple specifications. This not only reduces the number of independent negative pressure suction tubes of multiple specifications, but also brings convenience to operation and use. At the same time, since the front end of the negative pressure suction tube is an arc end part, it solves the problem that the conventional straight tube-shaped negative pressure suction tube cannot reach the expected position, which is conducive to intraoperative operation and avoids the failure of curettage operation and uterine perforation in the extremely forward or extremely backward position of the uterus.

[0016] Fig. 2 is a right side view of Fig. 1;

[0017] Fig. 3 is a schematic diagram of the exploded structure of Fig. 1;

[0018] FIG. 4 is another embodiment of the connector of the upper and lower sections of FIG. 1 . Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] The medical artificial abortion negative pressure suction tube shown in Figures 1 to 3 is composed of an upper section 1 and a lower section 4. In this embodiment, the upper section 1 is a structure from a straight tube section to a front end curved elbow. A suction hole 2 is provided at the abdominal position of the curved elbow. The suction hole 2 has an eccentric angle with the center of the inner diameter of the straight tube section of the upper section 1. A blind hole is formed from the inner diameter of the straight tube section to the curved elbow. The upper connector provided at the straight tube section position of the upper section 1 is a variable diameter internal thread 3. In this embodiment, the lower section 4 is a straight tube section. The lower connector provided at one end of the straight tube section is a variable diameter raised tube section, which is provided with an external thread 5, and is connected and combined into one piece with the internal thread 3 of the upper section through the external thread 5 of the lower section.

[0021] In the above description, the upper section 1 includes three specifications, and the length specifications thereof are 8 cm; 9 cm; and 10 cm respectively.

[0022] In the above description, the length specification of the lower section 4 is 8 cm.

[0023] In the above, the upper section 1 of different length specifications can be replaced and used in combination with the lower section 4.

[0024] FIG4 shows another embodiment different from the connector of FIG1. ​​It is improved on the basis of the connector of FIG1. ​​The difference is that the upper connector of the upper section 1 is provided with an inner countersunk hole 6 at one end of the straight pipe section. The lower connector of the lower section 4 is provided with a protruding plug 7 with a diameter change at one end of the straight pipe section, and the protruding plug 7 of the lower section 4 is directly inserted into the inner countersunk hole 6 of the upper section 1 to form a whole.

[0025] In the above, the combined connection mode of the inner countersunk hole 6 of the upper section 1 and the protruding plug 7 of the lower section 4 can be called an insertion connection.

[0026] The key to the implementation of the present invention is that the front end of the negative pressure suction tube adopts a curved elbow shape to avoid uterine perforation. At the same time, the suction port is set in the abdomen of the curved elbow, which can reach the expected position of the gestational sac and avoid abortion failure. In addition, the length specifications of the upper section 1 of the negative pressure suction tube assembly are 8 cm; 9 cm; 10 cm respectively, which can be combined with the lower section 4 respectively, so that the overall design of the negative pressure suction tube is simplified, and it is superior to the traditional negative pressure suction tube in terms of use function.

[0027] Operation:

[0028] 1. Take the lengths of the upper section 1, 8cm, 9cm, and 10cm respectively, and set them aside;

[0029] 2. Select the upper part of different lengths according to the depth of the uterine cavity 1;
