Guide device for correcting pectus excavatum

Abstract

The invention relates to a guide device for correcting pectus excavatum. The guide device for correcting pectus excavatum comprises a guide machine and an ultrasonic probe arranged on the guide machine, wherein the guide machine is provided with a handle and a long-sheet-shaped guide sheet; the guide sheet is arranged and fixed on the handle and extends towards an outer arc curve; a perforation is formed in the tail end part of the guide sheet; and the ultrasonic probe is arranged and fixed on the tail end part of the guide sheet and transmits and receives an ultrasonic signal towards the tail end part extending direction of the guide sheet. According to the structural design that the ultrasonic probe is arranged and fixed at the front end of the guide machine, the guide device can greatly reduce the possibility of damage to blood vessels or heart caused by the guide machine and can relatively reduce surgical risk when the guide device is applied to the pectus excavatum correction surgery.

Description

technical field [0001] The invention relates to a guiding device, in particular to a guiding device used for correction of thoracic concavity. Background technique [0002] The official medical name of the indentation of the thoracic cavity is Pectus excavatum, which is also commonly known as funnel chest. It is caused by abnormal hyperplasia of cartilage on both sides of the sternum, which leads to sternal invagination, resulting in a decrease in the distance from the sternum to the vertebrae. Symptoms It can range from mild unsightly appearance to severe cardiopulmonary compression. [0003] like figure 1 , figure 2 , image 3 As shown, the latest technology for the treatment of thoracic depression is Nuss procedure (Nassler's surgery), which is mainly through the correction of a depression adjustment rod (Nuss bar) 100 with a predetermined arc bending line into the chest cavity 200, to Protruding the sunken sternum 201 forward has become the most commonly used correc...

But because this thoracic endoscope 103 can only watch the right half of the heart 202, so once the front end of the guiding instrument 101 moves to the area between the heart 202 and the sternum 201, it is impossible to judge what the guiding instrument 101 hits when it advances. What kind of tissue does it reach, and because computerized tomography or X-ray photography cannot be performed during the operation, it can only rely on the clinical experience of the surgeon to judge the direction and angle of the guiding instrument 101, so it is inevitable that Cutting a blood vessel or stabbing the heart
