Abstract

The invention relates to the technical field of medical instruments, in particular to a thoracoscopic lung fixation device, comprising a lung clamping tool and a chest wall fixing device. The lung clamping tool comprises left and right clips, and two clips are articulated through a spring column. The head end of the clip is provided with a clip head, the tail end of the clip is provided with a rack, and the left rack and the right rack are provided with fixed clamping teeth capable of engaging with each other. The tail end of the clip is provided with a slot. Suspension wires are respectivelyarranged at the left and right ends of the spring columns, and the suspension wires are spaced at intervals of 1-3 cm position with beads. The chest wall fixing device comprises an elastic pipe, an inner clasp ring and an outer clasp ring respectively fixed at two ends, and a plurality of clasp grooves are arranged on the surface of the outer clasp ring. The device can reduce lung movement causedby beating and breathing of the heart, greatly reduce the range of lung movement during thoracoscopic operation, avoid lung movement from interfering with the operation of a doctor, and provide further guarantee for fine operation and operation safety of the operation.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a lung fixation device under a thoracoscope. Background technique [0002] Thoracoscopic surgery (video-assisted thoracoscopic surgery) uses modern camera technology and high-tech surgical equipment to complete complex intrathoracic surgery under the chest wall cannula or tiny incision. It has changed the treatment of thoracic surgery diseases. The concept, known as one of the major breakthroughs in the field of thoracic surgery in the last century, is a representative operation of minimally invasive thoracic surgery and the direction of future thoracic surgery development. Complete thoracoscopic surgery only needs to make 1 to 3 small holes of 1.5 cm in the chest wall. The tiny medical camera projects the situation in the chest cavity to the large display screen, which is equivalent to putting the doctor's eyes into the patient's chest cavity for surgery. The surgi...
