Description

Anatomical rib bone fracture plate under thoracoscope

Technical Field

The utility model relates to an appliance for the internal connection of the thorax under the thoracoscope, in particular to a bone fracture plate for internal fixation of rib fracture minimally invasive surgery, which belongs to the technical field of medical appliances.

Background

Ribs are easy to be wounded to cause fracture, unstable rib fracture with obvious flail chest and dislocation currently advocates rib fracture cutting and internal fixation treatment, conventionally, skin, muscle and periosteum tissues with enough length or multiple positions are cut on the chest wall under general anesthesia, after ribs at two sides of the fracture end are dissociated for 3-4 cm reduction, fracture is fixed by using a pure titanium rib bone fracture plate or a nickel-titanium memory alloy rib embracing device, and the like, particularly for rib fracture close to the back of a spine and shoulder blades, at present, a proper anatomical bone fracture plate is lacked, so that the bone fracture plate is not firm in fixation, even loosens and falls off, the possibility of damaging sacrospinous muscles and chest wall nerves is caused, functional disorder of muscles after operation is caused, the originally damaged tissues are subjected to larger trauma again, wounds are also susceptible, and treatment cost and pain of patients are increased. In order to solve the existing problems, the Chinese patent document discloses a rib fracture fixator under a thoracoscope, and the patent application numbers are as follows: ZL201120271141.9, the patent name is "implanting nickel titanium can memory alloy rib bone plate in thoracoscope", this rib plate is including supporting according to bone plate, armful arm, bone plate hole, armful arm hole, can absorb the pull wire to constitute, under thoracoscope guide, can absorb the pull wire and wear out the skin, make armful arm pierce through rib upper and lower edge, utilize the memory alloy effect, played fixed effect. Recently, a ZL201520658606.4 patent named as 'reversely-installed rib bone plate' is disclosed, which comprises an arc main beam and a plurality of arc holding arms arranged on two sides of a convex arc surface of the main beam at intervals. Because they are not anatomized, and because human rib of rib has different curvature and torsion degree in the front, middle and back regions, the height and width of cross section and the geometric form of inner side surface are not nearly the same, it is difficult for the arms at two ends of the rib bone fracture plate in the thoracoscopic cavity to adapt to the curvature and torsion degree of rib at the same time, they are made of nickel-titanium memory alloy, and in addition, it lacks ideal reset tool for resetting fracture at different positions in the thoracoscopic cavity, when it is mounted and fixed, it will be very difficult, the arms below can easily damage intercostal nerve and blood vessel, it also wastes time and labor when it is necessary to take down, and it also has the risk of causing the bone fracture plate to be fixed insecurity, even loose and fall off. Anatomically consistent rib plates may improve the likelihood of anatomic reduction and stability of reduction, significantly reducing surgical time, and thereby reducing the risk of infection. The blunt titanium is a novel structural material, has the characteristics of no magnetism, no allergy to a human body, strong plasticity, light weight, strong corrosion resistance, no absorption of titanium element by the human body and the like, and is a preferred material for the rib bone fracture plate in the thoracic cavity.
