Some methods for patent foramen ovale, while treating left atrial diseases, involve establishing a passageway to the left atrium through the foramen ovale. The main method for establishing the current channel is that under the guidance of the color ultrasound of the esophagus heart, the SWARTY sheath is used to pass through the patent foramen ovale and then exchange the guide wire or the right femoral vein access, and then the guide wire is sent into the SL1 atrial septum puncture sheath and the puncture needle, or under the guidance of X-ray, the atrial septum puncture sheath reaches the left atrium with the puncture room spacing slightly lower and before the puncture room spacing is slightly lower, and then the guide wire is exchanged. This can result in additional damage to the atrial septum when puncturing the atrial septum.
In view of the above, the embodiment of the application provides a patent foramen ovale bougie, which is characterized in that the distal end of a steel tube and the distal end of an expander are respectively arranged in a bending shape, the distal end of the steel tube does not exceed the distal end of a first expander, a guide wire is arranged in the steel tube in a penetrating way, the distal end of the guide wire can extend out, the patent foramen ovale position is conveniently detected, and the patent foramen ovale position is accessed, so that the patent foramen ovale position is hardly damaged, and the problem that in the related art, the patent foramen ovale instrument punctures the atrial septum to cause extra damage to the atrial septum can be solved to a certain extent.
As shown in fig. 1, 2 and 3, an embodiment of the present application provides an patent foramen ovale bougie comprising a dilator 10, a steel tube 20 and a guidewire 30. Wherein, in use, as shown in fig. 4, the guide wire 30, the expander 10 and the steel tube 20 are assembled together to have an assembled state. It should be appreciated that the guidewire 30 is typically relatively thin and does not substantially cause damage. The material of the dilator 10 is relatively soft and substantially atraumatic. The following will describe the various structures of the patent foramen ovale bougie, taking as an example the assembled state.
Wherein the expander 10 has a first cavity and the steel tube 20 has a second cavity. So that in the assembled state, the steel tube 20 is threaded into the first cavity of the dilator 10, the guidewire 30 is threaded into the second cavity of the steel tube 20, and the distal end of the guidewire 30 extends beyond the oval opening bougie (i.e., the distal end of the guidewire 30 extends from the distal end of the dilator 10).
Wherein the distal end of the dilator 10 has a first inflection zone 11; the distal end of the steel tube 20 has a second bending zone 21; in the assembled state, the second bending region 21 is disposed in the first bending region 11 in a penetrating manner, and the distal end of the second bending region 21 does not exceed the distal end of the first bending region 11.
In the assembled state, the proximal end of the expander 10 is fixedly connected to the proximal end of the steel tube 20, so that the steel tube 20 drives the expander 10 to rotate.
According to the patent foramen ovale bougie provided by the embodiment of the application, the first bending region 11 is arranged at the distal end of the expander 10, the second bending region 21 is arranged at the distal end of the steel tube 20, the steel tube 20 is penetrated in the first cavity of the expander 10 in the assembled state, the guide wire 30 is penetrated in the second cavity of the steel tube 20, the distal end of the guide wire 30 extends out from the distal end of the first bending region 11, the distal end of the second bending region 21 does not exceed the distal end of the first bending region 11, and the proximal end of the expander 10 is fixedly connected with the proximal end of the steel tube 20. Thus, the patent foramen ovale position is conveniently detected by the driving of the guide wire 30, and when the guide wire 30 guides the steel tube 20 to the patent foramen ovale position, the expander 10 can be driven to rotate by rotating the steel tube 20 so as to align to the patent foramen ovale position and enter the patent foramen ovale position, thereby directly entering the patent foramen ovale position without damaging the septum.
In some embodiments, the length of the orthographic projection of the second bending region 21 in the horizontal direction is smaller than the length of the orthographic projection of the first bending region 11 in the horizontal direction. It will be appreciated that second inflection zone 21 is itself shorter than first inflection zone 11 so that, in use, second inflection zone 21 is embedded within first inflection zone 11 without causing damage to the atrial septum when extending into the foramen ovale.
In some embodiments, the curvature R of the second inflection zone 21 may be 50 to 60mm, preferably 55mm. The curvature of the first inflection region 11 may be set according to the curvature of the second inflection region 21, and specific parameters may be satisfied to nest the second inflection region 21 in the first inflection region 11.
In some embodiments, the second inflection region 21 has an inner diameter that is greater than the inner diameter of the first inflection region 11 such that the first inflection region 11 is nested with the second inflection region 21. It will be appreciated that the second inflection zone 21 is less inflection than the first inflection zone 11, and that both may be nested in concentric circles to better expand the steel tube 20 through the expander 10.
In some embodiments, the length of the guidewire 30 is greater than the length of the dilator 10, and the length of the dilator 10 is greater than the length of the steel tube 20. In this way, the steel tube 20 can not be extended out of the expander 10, and the guide wire 30 can be extended out of the expander 10, so that damage can be reduced as much as possible.
In some embodiments, as shown in fig. 1, the dilator 10 includes a first tube 12 having a first cavity, the proximal end of the first tube 12 having a self-securing coupling 13, the self-securing coupling 13 for locking the first tube 12 to the proximal end of the steel tube 20. That is, the shaft of the dilator 10 (i.e., the first tube 12) has a joint at a proximal end and the distal end of the shaft (i.e., the first tube 12) has a first bend region 11.
In some embodiments, as shown in fig. 3, the distal end of the guidewire 30 has a visualization mark 31. Thus, the position of the distal end of the guide wire 30 can be conveniently judged through development, and whether the guide wire 30 reaches the patent foramen ovale is judged.
In some embodiments, the material of the development mark 31 is a developable platinum tungsten wire. It should be appreciated that the developable platinum-tungsten filament is an existing material and the present application is not directed to an improvement to the existing developable platinum-tungsten filament.
In some embodiments, the hardness of the guidewire 30 is less than the hardness of the first tube 12. That is, the hardness of the guidewire 30 is less than the hardness of the dilator 10, so that damage can be minimized.
In some embodiments, the steel tube 20 includes a second tube body 22 having a second cavity, and a direction indicator 23 is disposed at a proximal end of the second tube body 22, where an angle between the direction indicator 23 and the horizontal direction is the same as an angle between the second bending region 21 and the horizontal direction. It will be appreciated that the direction indicator 23 is used to indicate the orientation of the tip of the second bending zone 21. In this way, it is possible to easily judge the direction of the steel pipe 20 in the body.
In some embodiments, the hardness of the second tube 22 is greater than the hardness of the dilator 10. It will be appreciated that the material of the second tube 22 is steel, and the hardness of the second tube 22 is relatively high, while the hardness of the first tube 12 of the expander 10 is less than that of the second tube 22, so as to minimize damage.
In some embodiments, the direction indicator 23 is a pointer flange fixedly disposed at the proximal end of the second tube 22. The pointer flange has the advantages of simple installation, reliable indication and the like.
In some embodiments, the proximal end of the steel tube 20 has a joint 24, the joint 24 having a raised structure spaced apart or the surface of the joint 24 having a frosted structure. The holding force can be improved by arranging the convex structures at intervals, so that the steel pipe 20 can be better held during operation, the holding stability can be improved, and the like. By providing a frosted structure or the like on the surface of the joint 24, the holding stability can also be improved, facilitating better holding of the steel pipe 20 during operation.
When the patent foramen ovale bougie provided by the embodiment of the application is used, the guide wire 30 is arranged in the first cavity of the first tube body 12 of the expander 10 in a penetrating way, the distal end of the guide wire 30 extends out of the distal end of the first bending region 11 of the expander 10, and the distal end of the guide wire 30 also presents bending matched with the distal end of the first bending region 11 due to the softer material of the guide wire 30. The position of the distal end of the guide wire 30 can be judged by developing the developing material of the distal end of the guide wire 30, and whether the guide wire 30 reaches the position of the oval hole is confirmed. When it is confirmed that the guide wire 30 reaches the oval hole position, the steel tube 20 is guided into the expander 10, the guide wire 30 is penetrated into the steel tube 20, the second bending region 21 of the steel tube 20 is nested with the first bending region 11 of the expander 10 and does not exceed the first bending region 11, and the expander 10 is fixed at the proximal end of the steel tube 20 through the self-fixing joint 13 of the expander 10. In this way, the expander 10 and the guide wire 30 can be driven to rotate by rotating the joint of the steel tube 20, and the pointing direction of the tip of the second bending region 21 can be judged by the pointing direction of the pointer flange, so that the direction of the guide wire 30 and the expander 10 is adjusted, the patent foramen ovale position is detected, the guide wire 30 passes through the patent foramen ovale position in cooperation with an image, new damage can not be caused, and a channel can be established for subsequent operations.
According to the patent foramen ovale bougie provided by the embodiment of the application, the expander 10 is provided with the first bending area 11 in a bending shape, and the expander 10 is guided to the position of the foramen ovale through the guide wire 30 penetrating through the expander 10, so that the position of the foramen ovale is easy to reach. Then, the steel tube 20 is led into the expander 10, the guide wire 30 passes through the steel tube 20, the expander 10 is fixedly connected to the proximal end of the steel tube 20 by the joint at the proximal end of the expander 10, thus the distal end of the expander 10 can be driven to point by adjusting the joint at the proximal end of the steel tube 20, and the pointed end of the second bending region 21 can be judged to point by the pointer flange arranged at the proximal end of the second tube body 22, so that the pointed end direction of the steel tube 20 can be adjusted in time. By arranging the guide wire 30 with the tip provided with the strong developing polymer, and enabling the guide wire 30 to pass through and extend out of the steel pipe 20, the patent foramen ovale position is conveniently detected, tissues are not damaged, and a channel is established for the subsequent operation by matching images to enable the guide wire 30 to pass through the patent foramen ovale closing position.
