Detailed Description
The transapical access and closed recanalization device of the present invention will be described in further detail with reference to the accompanying drawings and embodiments of the invention.
As shown in fig. 1, 4 and 5, the transapical access and closed recanalization device comprises: the overall structure is a tubular structure of the guider 1 and a rod-shaped structure of the guide rod 2, one end of the guider 1 is fixedly connected with a fixed coil 3, the thread-shaped fixed coil 3 plays a role of a hard guide wire, and the fixed coil 3 penetrates into muscles of the heart wall by rotating the guider 1 to fix the guider 1 on the outer wall of the heart. In order to puncture a through hole in the heart wall, and because the strength of the heart wall is high, the heart wall is fibrous, the guide rod 2 is detachably inserted into the guide 1, the end part of the guide rod 2 extends out of the guide 1, the guide rod 2 is inserted into the heart wall at one end of the fixed coil 3 through the relative movement between the telescopic guide rod 2 and the guide 1, and the through hole is torn in the heart wall. Preferably, the end part of the guide rod 2 is blunt in arc transition, so that fibers on the heart wall are prevented from being cut off, damage to the heart is reduced, and the heart can be recovered more quickly; further, the less the damaged fibers are, the stronger the fixing strength of the fixing coil 3 around the fibers is. Therefore, the through hole is formed in the heart apex position preferably on the heart wall of the patient, the purpose of multiple operation treatment in the heart is met, multiple times of opening holes for treatment caused by multiple complications in the heart are avoided, the recovery period is slow, the health of the patient is influenced, and the difficulty of each operation is increased.
In order to realize the detachment of the guide device 1, the through hole formed on the heart wall can be used in a plurality of operations, and the through hole can be protected and positioned. The guide 1 comprises: a cannula 11 for conducting the outside of the patient's body and a fixing cap 12 for fixing to the outer wall of the patient's heart. The fixing cap 2 is in an open shape, so that the contact area between the fixing cap and the heart wall of the patient is increased, the sealing performance is guaranteed, and the use safety is further guaranteed. For more convenient detachment and connection between the fixing cap 12 and the sleeve 11, the reduced end of the fixing cap 12 is snapped into the sleeve 11. The fixing coil 3 is fixedly connected inside the fixing cap 12, so that the fixing coil 3 is partially arranged inside the fixing cap 12, when the fixing coil 3 is spirally penetrated into the heart wall, the fixing coil 3 tensions the muscle of the heart wall, and partial heart wall is drawn into the fixing cap 12, so that the sealing effect between the fixing cap 12 and the heart wall is further improved. Of course, in order to achieve a smoother penetration of the fixation coil 3 into the heart wall, the tip of the fixation coil 3 extends beyond the end face of the open end of the fixation cap 12.
As shown in fig. 2 and 3, it is further preferable that a non-slip mat 6 is fixedly connected to the inner cavity of the fixing cap 12 and the open end of the fixing cap 12, and preferably, the non-slip mat 6 is made of medical rubber material, so as to be used inside the human body and be used inside the human body for a long time.
As shown in fig. 1, 2, 3, 4 and 5, in order to ensure the safety of the recanalization device and to avoid the blood pressure inside the heart from being high, the blood pressure is jetted out of the through hole to affect the health of the human body. The conducting pipeline between the inner cavity of the fixing cap 12 and the sleeve 11 is a one-way conducting cavity 13. Through the one-way conduction cavity 13, the one-way conduction cavity 13 is closed under the action of the blood pressure in the heart, and the blood in the heart cannot flow out of the heart.
In order to realize the function of one-way conduction to the one-way conduction cavity 13, it is preferable that the one-way conduction cavity 13 includes a through hole 131 provided therethrough, and a one-way conduction ball plug 132 is provided inside the through hole 131. The one-way conduction cavity 13 is simple in structure, only one-way conduction ball plug 132 achieves the one-way conduction effect, and the effect that the one-way conduction of the one-way conduction cavity 13 is influenced by the fact that the one-way conduction cavity 13 is located inside a human body for a long time and extravasated blood is formed inside the one-way conduction cavity 13 is avoided.
Further, in order to introduce the conveying system into the through hole 131 during the operation, the conveying system can pass through the through hole 131 more smoothly, and interference between the conveying system and the one-way conducting ball plug 132 at the temporal part of the through hole is avoided, especially because the one-way conducting ball plug 132 blocks the inside of the through hole 131, the space for the conveying system to penetrate through the through hole 131 is too small, and the operation effect is affected. A retraction groove 133 of the one-way conduction ball plug 132 is provided on the side of the through hole 131, so that the guide rod 2 pushes the one-way conduction ball plug 132 into the retraction groove 133, and the through hole 131 is conducted in the hole center axis direction. It is possible to leave more space for the delivery system to pass through the via hole 131, ensuring smooth operation of the delivery system.
In order to ensure that the guide rod 2 can uniformly penetrate into the heart wall and can tighten the heart wall, the heart wall is prevented from being penetrated under the action of external force, and the heart is seriously damaged. The outer wall of one end of the sleeve 11 far away from the fixing cap 12 is provided with an external thread, the guide rod 2 is far away from the one end of the fixing cap (12) and fixedly connected with the tightening cap 4, the inner wall of the tightening cap 4 is provided with an internal thread, the external thread of the outer wall of the sleeve 11 is matched with the internal thread arranged on the inner wall of the tightening cap 4 to drive the guide rod 2 to be inserted into the sleeve 11, and the end part of the guide rod 2 is penetrated into the heart.
Preferably, the inner wall of one end of the connecting sleeve of the fixing cap 12 is provided with a clamping groove 121, the outer wall of the sleeve 11 is provided with a clamping protrusion adapting to the clamping groove 121, and the clamping protrusion and the clamping groove 121 are matched to enable the fixing cap 12 to be detachably connected with the sleeve 11.
In order to further ensure that the fixing cap 12 can better seal the through hole on the heart wall after the operation is finished, the poor sealing effect of the one-way conduction ball plug 132 of the fixing cap at the position of the through hole is avoided, and the use safety of the whole recanalization device is not influenced. This rethread device still includes: the outer wall of the sealing plug screw 5 is provided with threads, the inner wall of one end of the fixed cap 12 connecting sleeve 11 is provided with inner threads, and the sealing plug screw 5 is detachably connected with the inner threads inside the fixed cap 12 in a matched manner. When the fixing cap 12 is temporarily stored in the patient, the sealing effect of the fixing cap 12 is further ensured through the sealing screw plug 5, and the blood in the heart is prevented from flowing out.
In order to facilitate the screwing of the sealing screw plug 5, a screwing notch is formed at one end of the sealing screw plug 5, which is far away from the fixing cap 12. Preferably, the end part of the guide rod 2 is detachably connected with a screwing device which is matched and connected with the sealing screw plug 5, so that the sealing screw plug 5 at the screwed groove opening can be conveniently screwed.
In order to meet the strength of the fixed coil 3 and the health requirements on the human body, the fixed coil 3 is a titanium alloy coil.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
