Abstract

The invention provides a minimally invasive coronary artery bypass proximal anastomosis assisting instrument. The assisting instrument comprises a tube wall clamp and a tube wall clamp adjusting mechanism, wherein the tube wall clamp comprises a tube wall clamp body, and a control circuit board and a power supply module are arranged in the tube wall clamp body; a control switch and a display module are arranged on the top or the rear end face of the tube wall clamp body; an upper retaining ring clamp and a lower retaining ring clamp are both provided with a pressure sensor; the pressure sensors are connected with the control circuit board through wires so as to process pressure input signals of the pressure sensors; the control circuit board is electrically connected with the power supplymodule, the control switch and the display module separately, switch-on and switch-off signals of the control switch are received, and display information is generated according to the pressure inputsignals and sent to the display module to be displayed. By means of the minimally invasive coronary artery bypass proximal anastomosis assisting instrument, the strength of force applied to blood vessels in the operation process can be detected in real time and visually displayed to an operator, the operator is strikingly guided to master and adjust the intensity of the force at any time, and thesafety of the blood vessels is greatly ensured.

Description

technical field [0001] The invention relates to a proximal anastomotic auxiliary device for minimally invasive coronary artery bypass grafting. Background technique [0002] The invention patent with the patent number ZL201220301496.2 discloses a minimally invasive proximal anastomotic auxiliary device for coronary artery bypass grafting, which is mainly aimed at improving the simplicity of operation, reducing bleeding and protecting blood vessels. The protection only gives a solution on part of the structure, but one of the most important reasons for ignoring the trauma to the blood vessels is the force during the operation. When the force is too large, no matter how good the structural design is, it cannot avoid damage to the blood vessels. trauma. However, the use of the proximal anastomotic auxiliary instrument for minimally invasive coronary artery bypass grafting can only be based on the operator's feel or experience, and there are great uncertainties and potential sa...
