Problems solved by technology

[0003] The pruning of the lungs has the following problems: 1. It prolongs the time of the lungs outside the body; 2. The pruning of the lungs increases the difficulty of the operation and there is a risk of damaging the lungs; 3. The lung lobes are usually considered to be surgical treatment Anatomically the smallest resected unit, less lung volume also means reduced lung function in post-transplant patients

Embodiment 1

[0018] A multifunctional medical chest wall reconstruction device provided in this embodiment includes a rib expander 2, a chest protective sheet 4 and a buckle 5. The rib expander 2 is in the shape of a long strip, and a third rib is provided at both ends of the rib expander 2. A contact plate 2-1, the first contact plate 2-1 is symmetrically provided with a positioning boss 2-2 along the central axis, and the middle position of the rib expander 2 is provided with a positioning groove 2-3, and the first contact plate 2-1 A holding claw 3 is provided. The main body of the holding claw 3 is symmetrically provided with a positioning through hole 3-1 along the central axis. The positioning through hole 3-1 cooperates with the positioning boss 2-2 to fix the position of the rib expander 2. The holding claw 3 There are claw hooks 3-2 around, and the claw hooks 3-2 can fix the claws 3 on the ribs 1. There are a plurality of through holes 4-1 evenly distributed on the chest cavity pro...

Abstract

The invention discloses a multifunctional medical thoracic cavity wall reconstructor. The multifunctional medical thoracic cavity wall reconstructor comprises a rib expander, a thoracic cavity protection sheet and a buckle, the rib expander is implanted between two ribs to expand the distance between the two ribs; the rib expander is fixed on the rib through the holding claws; then, a thoracic cavity protection sheet is implanted between the two rib expanders; the fixing device is used for protecting the thoracic cavity and fixing the relative position between two rib expanders. The rib expander and the thoracic cavity protection sheet have different specifications so as to meet the requirements of different patients; the device is simple and practical, the thoracic cavity of a lung transplantation receptor can be effectively expanded to adapt to the size of the lung of a donor, the lung function of a receptor patient is improved, the lung of the donor is prevented from being cut, andmeanwhile the implant has enough hardness and toughness and has good biocompatibility.

Description

technical field [0001] The invention relates to medical equipment, in particular to a multifunctional medical chest wall reconstructor. Background technique [0002] Lung transplantation is the only treatment for end-stage lung disease. Currently, lung transplantation includes single-lung transplantation, single-lung transplantation combined with contralateral lung volume reduction, and double-lung transplantation. Since the concept of brain death in China has not been widely accepted by the public, the lungs in China mainly come from DCD donor lungs. Moreover, compared with other tissues and organs, lung tissue is more susceptible to damage, and isolated lungs are not easy to preserve. Clinically, the time between obtaining a donor lung and transplanting should be shortened as much as possible. Due to the huge domestic demand, the number of donor lungs available for transplantation in China is insufficient, and patients have to wait a long time before they can get the opp...
