A medical magnet tunnel dilation device for congenital anal atresia

Abstract

The present invention discloses a medical magnet tunnel expansion device for congenital anal atresia, comprising a first sub-magnet, a second sub-magnet, a first mother magnet and a second mother magnet, wherein a groove is provided on the top of the first sub-magnet, and the present invention relates to the technical field of medical devices. The medical magnet tunnel expansion device for congenital anal atresia has a tendency to pass through this potential gap under the action of continuous magnetic force through the first sub-magnet, the second sub-magnet, the first mother magnet and the second mother magnet, and the intestinal wall has a certain elasticity and can be displaced toward the perineum side with the magnet. Based on this anatomical characteristic, the constant magnetic force characteristic of the magnet can be utilized to establish a natural cavity in the center of the pelvic floor muscle, so that the blind end of the rectum of the child with anal atresia slowly descends along the muscle center toward the perineum side. The diameter of the groove on the first sub-magnet is 0.5 cm, and different magnets can be selected according to different children to improve adaptability.

Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a medical magnet tunnel expansion device for congenital anal atresia. Background Art

[0002] Congenital anal atresia is the most common digestive tract malformation, with an average of 1 in every 3,000-5,000 newborns suffering from this disease. The pathogenic mechanism of the disease is not yet clear, but most theories point to its relationship with the abnormal spatiotemporal development of the pelvic floor muscles and cloaca. Laparoscopic anoplasty is the mainstream procedure at this stage. The key and difficulty of the operation is to create a tunnel in the center of the pelvic floor muscles and drag the rectum out of the tunnel to establish a normal anatomical relationship between the rectum and muscles. At present, the establishment of the perineal tunnel is guided by an electrical stimulator, but the establishment of the pelvic tunnel is a "semi-blind" process. According to the inventor's previous research, the pelvic floor muscles are a whole, funnel-shaped, and the pelvic floor muscles and external sphincters of children with anal atresia are in a closed state, with a potential gap in the center of the muscles.

[0003] The treatment of congenital anal atresia has gone through procedures such as blindly separating the surgeon's fingers to form a tunnel and splitting the pelvic floor muscles in the middle to identify the muscles. The above methods have the disadvantages of missing the muscle center, causing muscle damage, and forming scars around the rectum, which leads to complications such as postoperative incontinence and constipation in children, seriously affecting the quality of life of children and placing a heavy burden on families and society. After the 20th century, laparoscopic anoplasty emerged, which has the advantages of minimally invasive, avoiding splitting the pelvic floor muscles, and improving the treatment effect. However, accurately forming a tunnel from the abdominal side to the perineum side is still a difficult point in the operation, affecting the efficacy and hindering its promotion and application. At present, the establishment of the perineal side tunnel is guided by an electrical stimulator, but the establishment of the pelvic side tunnel is a "semi-blind" process, mostly based on the surgeon's experience, and some patients still have the risk of the rectum deviating from the muscle center after surgery. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a medical magnet tunnel expansion device for congenital anal atresia, which solves the problem that the prior surgery easily causes the rectum to deviate from the muscle center or damage the muscle.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a medical magnet tunnel expansion device for congenital anal atresia, comprising a first sub-magnet, a second sub-magnet, a first mother magnet and a second mother magnet, a groove is provided on the top of the first sub-magnet, and a cross bar is welded between the two sides of the inner wall of the groove, a hanging ring is welded on the top of the second sub-magnet, and a protrusion is provided on the top of the second mother magnet, the first mother magnet is cylindrical, and the second mother magnet is roughly in the shape of a mountain.

[0006] Preferably, the first sub-magnet and the second sub-magnet are both 1.5 cm in height and 1.2 cm in diameter, and are generally conical in shape with a bottom cone height of 0.6 cm. The first sub-magnet and the second sub-magnet are both made of N52 sintered NdFeB and coated with titanium nitride film on the surface.

[0007] Preferably, the diameter of the groove on the first sub-magnet is 0.5 cm, and the top magnetic pole of the first sub-magnet is N, and the bottom magnetic pole is S.

[0008] Preferably, the diameter of the upper hanging ring of the second sub-magnet is 0.5 cm, and the top magnetic pole of the second sub-magnet is N, and the bottom magnetic pole is S.
