Description

Autologous pericardium taking and placing device

Technical Field

The utility model relates to the field of medical equipment, concretely relates to autologous pericardium is got and is put device.

Background

The pericardium is a membranous sac covering the surface of the heart. The pericardium comprises a fiber layer and a serous layer, wherein the fiber layer is tough, tightly adhered to the wall layer of the serous layer, and has low elasticity. The serosal layer is thin, smooth and moist, and is divided into a wall layer and a visceral layer, wherein the wall layer is attached to the inner surface of the fibrous layer, and the visceral layer is attached to the surface of the heart (i.e. epicardium). A cavity is arranged between the two layers of the heart and the wall, the pericardium is called as the pericardial cavity, has the protective effect on the heart and can prevent the heart cavity from being excessively enlarged so as to keep the blood volume constant.

However, the autologous pericardium has good biological characteristics, and in recent years, the application of the autologous pericardium in the open-heart surgery repair finds that the local mechanical strength of the autologous pericardium tissue of a human body is moderate, good flexibility, long durability, easy growth and attachment after sewing, difficult blood leakage, low incidence rate of residual leakage after operation, no rejection reaction, strong anti-infection capability, therefore, the fabric is widely applied to open-heart surgery, gradually replaces artificial polyester fabric repairing materials, in the current operation process, after a doctor takes off the pericardium and hands the pericardium to a nurse, the nurse needs to unfold and fix the autologous pericardium and cannot influence a transfer apparatus at the same time, but the two methods cannot be considered, during the operation process, a nurse is busy fixing the autologous pericardium to delay the transmission of the instrument, the operation process is influenced, or the self-pericardium is too soft or not flat enough to affect normal use because the self-pericardium is delayed to be fixed in time due to busy transferring instruments.

Therefore, the autologous pericardium taking and placing device is simple in structure, convenient to operate, easy to popularize and capable of ensuring that the autologous pericardium is flat, and has a wide market prospect.
