Description

Lateral position hand rest for heart minimally invasive surgery assisted by axillary thoracoscope

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to through side position hand rest of armpit thoracoscope assisted heart minimal access surgery.

Background

With the deepening of the minimally invasive concept of the surgical operation and the increasingly mature thoracoscopic technology, the minimally invasive incision through the right armpit has the advantages of small wound, attractive incision, quick recovery and the like in comparison with the median incision of the sternum during the cardiac operation, and is more easily accepted by patients.

In order to fully expose the operative field, the body position requires the right upper limb to be lifted over the vertex and be in a salutary shape, in order to ensure that the operative field is stably exposed in the operation and avoid the injury of the angioneurotic nerve caused by the fact that the joint activity exceeds the physiological range due to the relaxation of the shoulder joint after anesthesia, the right upper limb is lifted over the vertex when the body position is placed, and the right upper limb is properly fixed when the right upper limb reaches the target angle. In clinical practice, for avoiding influencing the operation of the operative person with the supporting side clinostatism hand rest dead lever of operation table, the side clinostatism hand rest dead lever is settled in the operation table left side, when leading to using the fixed patient's right upper limbs of current side clinostatism hand rest, the hand rest of hand rest can only support right upper limbs elbow joint distal end position, including right side forearm and hand, and the right side upper arm is in unsupported state, make the upper arm on the one hand easily because the effect of gravity slippage downwards, on the other hand receives unconscious extrusion when the operative person operates, forearm under the general anesthesia muscle pine state moves along with pushing, easily lead to the shoulder joint passively to exceed physiological movement range, to shoulder joint and adjacent vascular nerve, such as brachial plexus nerve, axillary artery, axillary vein etc. cause the damage.

In summary, the lateral position hand frame plays an important role in assisting the minimally invasive cardiac surgery through the axillary thoracoscope, but the existing lateral position hand frame has the problems of influencing the operation of the surgeon, easily causing the joint and nerve injuries of the patient and the like, and further improvement is needed urgently.
