Description

Hernia patch

Technical Field

The invention belongs to the field of implant interventional medical instruments, and relates to a hernia patch.

Background

Hernia refers to the condition that the viscera leave the original location and enter another location through the weak points, defects, or pores of the human body. The most common site for hernia is the abdomen. An abdominal external hernia refers to the protrusion of internal organs of the abdomen through congenital or acquired defects or weak areas of the abdominal wall to the body surface, forming a lump locally.

The introduction of polymeric networks in hernia patch suture surgery has been shown to reduce the recurrence rate and pain, thereby improving the healing efficacy of the patient. The implantation of the patch into the body makes surgery a tension-free prosthesis and the importance of the patch makes the patch a critical factor for surgery and prognosis.

Currently, patches are fixed to the body tissue using the outer circumference to resist the pressure of the internal organs. But also brings with it a number of problems: the suture requirement of the periphery of the patch and human tissues is high; the patch has high strength requirement and cannot be light to the maximum extent; the patch has large stress surface and uneven stress and generates deformation.

For internal organs, the restoration of the internal organs is guaranteed under the combined action of the peripheral tension and the magnetic force of the patch body. For the abdominal wall, the pressure of the internal organs on the abdominal wall is reduced, the rehabilitation of the abdominal wall is facilitated, and the infiltration, adhesion and growth of fibrous connective tissue cells on the patch are facilitated.

4. The bulges are clamped in the meshes and matched with the magnetic receiving ring and the threading holes to realize the fixation of the magnet on the patch body.

5. The arrangement of the external magnet makes the magnet on the patch have a magnetic force source, and the air bag and the pressure sensor probe are used for sensing the pressure of the external magnet on the air bag and reflecting the visceral pressure to a certain extent.

6. The hernia belt is an auxiliary means of tension-free repair, on one hand, the pressure on the abdominal wall is considered, on the other hand, external organs such as testis are considered, the invention effectively avoids the problems by adopting magnetic force, and the bandage is used for fixing an external magnetic device and is not hernia reduction in the present sense.

7. The magnet is designed into a sheet shape, has light weight, reduces the foreign body sensation in the body, has large action surface and is easy to fix.

8. The magnet is covered with human body adaptive material to prevent inflammation caused by direct contact between the magnet and human body.
