Description
Technical Field
The invention relates to the technical field of heart operation tools, in particular to a wound supporting and avoiding device for heart operation.
Background
The cardiology department is a younger subject of the surgical field, and is primarily a surgical treatment for heart disease, such as heart bypass surgery, congenital heart disease surgery, valve replacement, etc. The common heart diseases to be treated are: congenital heart disease, valvular heart disease, coronary heart disease, thoracic aortic aneurysm, pericardial disease, heart tumor, etc., wherein when the surgery is performed on the part of the patients, an operation opening needs to be cut on the chest of the human body to realize the direct operation on the heart by medical staff, wherein the most basic needs to ensure the success of the surgery include the following aspects; 1. the operation opening is maximized when the wound is fixed; 2. the operation is carried out without obstacles; 3. during operation, the peripheral tissues are protected;
the intellectual property office of China discloses a patent with application number 201720802015.9, which comprises a first supporting piece, a second supporting piece and a closing device, wherein one end of the first supporting piece is connected with one side of a wound, and one end of the second supporting piece is connected with the other side of the wound; the free end of the first supporting piece is movably connected with the free end of the second supporting piece, so that two sides of the wound can be mutually closed; the first support part and the second support part support the closing device to isolate the wound from the outside. The first support member and the second support member are connected with the wound, so that the skin grows in a moderate elastic deformation range, and the wound healing speed is increased. For the condition of large wound, the condition that the skin on the two sides of the wound can not be sutured in a short time or the skin tissue is pulled apart is avoided. The wound is isolated from the outside by the arrangement of the closing device. The wound is healed in a clean environment.
But the assistive device is used along with production, and the defects of the technology are gradually exposed:
first, as is well known, when a doctor of a main surgeon performs a cardiac operation, other assisting doctors need to perform an assisting operation, and in order to ensure a smooth operation of the doctor of the main surgeon, the assisting doctors need to open an operation opening of a patient so as to ensure an operation space of the doctor of the main surgeon.
Secondly, when the assistant doctor opens the wound, especially for many hours of operation, the hand of the assistant doctor is powerless, so that the opening area of the operation opening is not guaranteed to be constant, the injury to the patient is caused, and the operation of the main doctor is directly influenced.
Thirdly, in the process of operation, a plurality of tissues are passed from the skin surface to the heart, so that the auxiliary doctor cannot limit the peripheral tissues when opening the operation port, and the avoidance of the peripheral tissues is required to be ensured when the main doctor operates, thereby increasing the operation difficulty and prolonging the operation time.
Fourthly, since the operation patients have different ages, the sizes of the operation ports are different, and the operation is limited to diversification, so that the operation difficulty of the assistant doctor is increased.
Fifthly, the distance from the skin to the heart is different due to different human bodies of each person, so that the limitation is different, the operation requirement on an assistant doctor is greatly limited, and the operation difficulty of the assistant doctor is improved.
Therefore, in the existing cardiac surgery, medical staff can open the wound around how to ensure the operation of the basic main doctor, but the medical staff is limited by the obstruction of instruments and human bodies and cannot ensure the maximum operation space; the operation difficulty of assisting doctors is improved because the opening and closing sizes and thicknesses of the operation openings are different due to the fact that the operation openings are limited by different human bodies; and the operation difficulty of the main surgeon is improved and the operation time is prolonged due to the limitation of peripheral tissues.
In view of the above, the prior art is obviously inconvenient and disadvantageous in practical use, and needs to be improved.
