Problems solved by technology

[0003] At present, there are mainly two types of guiding catheters for embryo transfer in the prior art, one is a straight tube, which is used for common patients, and for patients with complicated uterine anatomy, it is difficult for this kind of guiding catheter to smoothly enter the patient's cervix One is the pre-shaped guide catheter, which can be used for complicated uterine anatomy. However, the bending angle of the pre-shaped guide catheter is usually fixed. Although it can solve some patients with abnormal anatomical shapes, it is suitable for Some patients whose anatomical shape and shaping angle are relatively matched, but still cannot adapt to the conditions of all different patients

Embodiment 1

[0044] Please refer to Figure 1-13 In this embodiment, the embryo transfer device includes a hollow handle 10 , a guide tube 20 , an adjustment device and a traction wire 40 . The handle 10 is provided with a groove 101 extending along its axial direction, the guide tube 20 is a plastic hollow body structure with openings at both ends, and the inner cavity of the guide tube 20 is communicated with the inner cavity of the handle There is a traction channel 201 between the inner wall and the outer wall of the guide tube 20; the adjustment device includes a movable adjustment member 30 arranged in the groove 101; the first end of the traction wire 40 is inserted into the traction channel 201 and fixed in the guide On the guiding tube 20 , the second end of the pulling wire 40 is connected with the adjusting member, so that the guiding tube 20 can be bent under the pulling action of the pulling wire 40 . It can be seen that, when the present invention is in use, since the guide ...

Embodiment 2

[0063] Please refer to Figure 14-15 The difference between this embodiment and the first embodiment is that the path of the pulling wire 40 passing through the pulling channel 201 and connecting with the adjusting member 30 is different.

[0064]In this embodiment, the first through hole 1012 is opened on the side wall of the groove 101 facing the guide tube 20 and penetrates through the side wall, and the second through hole 205 is also opened on the outer wall of the guide tube 20 and is connected with the traction channel 201 are connected, but the second through hole 205 is not in the inner cavity of the handle 10, that is, it is exposed to the outside. The through hole 1012 and the second through hole 205 enter the pulling channel 201 . Therefore, it can be seen that part of the pulling wire 40 is exposed to the outside. Compared with the first embodiment, which involves the pulling wire 40 passing through the pulling channel 201 and connecting with the adjusting member...

Abstract

The adjustable embryo transplantation device comprises a hollow handle, a guide catheter, an adjusting piece and a traction wire, a groove which is not communicated with an inner cavity of the handle is formed in the outer wall of the handle, and strip-shaped sawtooth parts which are oppositely arranged are arranged on the two opposite side walls of the groove in the length direction of the groove; the guide catheter is of a moldable hollow tube body structure with openings in the two ends, the guide catheter and the sawtooth part are arranged in the same direction, the guide catheter is communicated with the inner cavity of the handle, a traction channel is arranged between the inner wall and the outer wall of the guide catheter, and the traction channel and the groove are located on the same side; the adjusting piece is movably arranged in the groove and is provided with two elastic ribs which are oppositely arranged, and the elastic ribs are provided with protrusions meshed with the sawtooth parts; one end of the traction wire is fixed to the adjusting piece, and the other end of the traction wire is located in the traction channel and fixedly arranged on the guide catheter, so that the traction wire can bend the guide catheter towards the side with the traction channel, and the bending degree of the guide catheter can be directionally and quantitatively adjusted.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an adjustable embryo transfer device. Background technique [0002] Embryo transfer is a crucial part of ART (Assisted Reproductive Technology), and in the process of embryo transfer, the time of surgery is one of the key factors affecting embryo development and survival. Therefore, how to help doctors quickly establish a channel for embryo transfer during surgery so that the embryo can be transferred into a patient in the shortest possible time has become a hot spot in the field of assisted reproduction. [0003] At present, there are mainly two types of guiding catheters for embryo transfer in the prior art. One is straight catheters, which are used for common patients. For patients with complex uterine anatomy, such catheters are difficult to smoothly enter the patient's cervix. One is the pre-shaped guide catheter, which can be used for complicated uterine anatomy. H...
