At present, medical treatment is the general rod-type intrauterine contraceptive loop placement device that has U type prong that adopts when placing the assembly of intra-uterine contraceptive utensil clinically, it is sent into intrauterine after intrauterine contraceptive loop being placed on U type prong in use.In fact in the ring process, because U type prong does not have the function of gripping, intrauterine contraceptive loop very easily comes off from U type prong, help to fix as being connected with intrauterine contraceptive loop with silk thread, the palpus bimanualness easily makes the position change of ring when moving back fork and line taking, influence contraceptive effect, and line taking inconvenience, operating difficulties.

The utility model content

Goal of the invention of the present utility model provide a kind ofly be convenient to operate, the intrauterine contraceptive loop placement device of intrauterine contraceptive loop difficult drop-off.

The technical solution of the utility model is: a kind of intrauterine contraceptive loop placement device is provided, comprises with handle links and send the ring bar, it is characterized in that: the described periphery of sending ring bar 3, and the edge cover is provided with open-core type and send eyelet thimble 1; Open-core type send eyelet thimble 1 to be socketed in to send sending between ring end and the handle 2 of ring bar 3;

The described ring that send of ring bar 3 that send is held, and elastic clamp ring head 4 is set, and elastic clamp ring head 4 stretches out open-core type and send eyelet thimble to send outside the ring end 9; Described sending on the handle end that encircles bar 3 is provided with alignment pin 5 and back-moving spring 7, and alignment pin 5 connects with handle 2 through back-moving spring 7;

Described open-core type is sent on the tube wall of eyelet thimble handle end 10, and the L shaped locating slot 6 that holds alignment pin 5 is set; Hold back-moving spring 7 in the tube chamber of L shaped locating slot 6.

Above-mentioned intrauterine contraceptive loop placement device is characterized in that described open-core type send the outer surface of eyelet thimble 1 that scale mark 8 is set.

Above-mentioned intrauterine contraceptive loop placement device is characterized in that it is straight tube that described open-core type is sent eyelet thimble 1.

Above-mentioned intrauterine contraceptive loop placement device, what it is characterized in that described open-core type send eyelet thimble 1 send ring end 9, is set to meet the radian of women's affected part physiological structure.

Compared with the prior art, the utility model has the advantages that:

1. the contraceptive device placement location is accurate, and the position of contraceptive device can change when the placement bar withdraws from the uterus.

2. easy to operate, one hand can be operated.

3. simple in structure, cost of manufacture is low.

Description of drawings

Below in conjunction with drawings and Examples this utility model is described further.

Fig. 1 is an overall structure sketch map of the present utility model;

Fig. 2 is that the A of L shaped locating slot among Fig. 1 is to local enlarged diagram;

Fig. 3 is the sketch map of another embodiment of this utility model.

1 send eyelet thimble for open-core type among the figure, and 2 is handle, and 3 for sending the ring bar, and 4 is the elastic clamp ring head, 5 is alignment pin, and 5-1 is a position of alignment pin, and 5-2 is another position of alignment pin, 6 is L shaped locating slot, and 7 is back-moving spring, and 8 for being arranged on the scale mark that open-core type is sent eyelet thimble 1 outer surface.

The specific embodiment

Among Fig. 1, the periphery of clamp ring bar 3, edge cover is provided with open-core type and send eyelet thimble 1, and open-core type send eyelet thimble 1 to be socketed in to send sending between ring end and the handle 2 of ring bar 3;

Send the ring that send of ring bar 3 to hold, elastic clamp ring head 4 is set, elastic clamp ring head 4 stretches out open-core type and send eyelet thimble to send outside the ring end 9; Send on the handle end that encircles bar 3 alignment pin 5 and back-moving spring 7 are set, alignment pin 5 connects through the handle 2 of back-moving spring 7;

Open-core type is sent on the tube wall of eyelet thimble handle end 10, and the L shaped locating slot 6 that holds alignment pin 5 is set; Hold back-moving spring 7 in the tube chamber of L shaped locating slot 6.

Among Fig. 2, local enlargement display is positioned at open-core type and send L shaped locating slot 6 on the tube wall of eyelet thimble 1 handle end 10, its vertically long limit and open-core type send eyelet thimble 1 axially in the same way, its horizontal minor face and open-core type send eyelet thimble 1 radially in the same way, alignment pin 5 can move along the vertical long limit of L shaped locating slot, or moves along the minor face of L shaped position groove; Drive during alignment pin 5 displacements and send ring bar 3 in hollow bushing, to vertically move, the intrauterine contraceptive loop that is held when sending 3 displacements of ring bar do simultaneously displacement (clamp intrauterine contraceptive loop when sending ring bar 3 vertically to retreat---send ring; Send ring bar 3 vertically to protract and laterally can decontrol that intrauterine contraceptive loop---intrauterine contraceptive loop is sent into cavity of uterus when mobile).

The sketch map of another embodiment of Fig. 3 this utility model, its open-core type send the ring that send of eyelet thimble 1 to hold 9, are set to meet the radian of women's affected part physiological structure, are easier to operation during actual the use.
