Built-in instrument for correcting thoracic deformity

Abstract

The invention discloses a built-in instrument for correcting thoracic deformity, the instrument comprises a support plate and a locking screw. The invention adopts a tenon-mortise structure composed of an insertion tenon and an insertion socket arranged at one end of the two support plates, the tenon-mortise structure of the two support plates is butted, the tenon-mortise structure is located in the roughly middle part of the two mutually butted support plates and is fastened by a locking screw; the invention has only one incision when correcting the patients with funnel chest and chicken chest, and has little trauma. A special mortise and tenon structure is used to bind and fix the support plate in the middle of the chest, and the two blunt tails extend into the left and right chest wallsrespectively, so as to ensure that the support plate will not affect the growth and development of the child's skeleton. In addition, the invention does not have the problem that the traditional pectus excavatum orthopedic operation needs to be guided through the chest by the penetrator, the tissue injury is small, the foreign body feeling after the operation is weak, and the pain of the patientis greatly reduced.

Description

technical field [0001] The invention relates to the technical field of implanted medical devices, in particular to a built-in chest deformity correction device. Background technique [0002] Pectus excavatum and chicken breast are congenital diseases, which not only affect the patient's respiratory system and cardiopulmonary system, but also hinder the patient's bone development and healthy growth. Minimally invasive surgery is often used to correct the corrective device into the chest. , most of the orthodontic devices in the prior art are single support plates, which are fixed at both ends. The existing problem is that the correction method of fixation at both ends will affect the bones to a certain extent for children with high incidence of pectus pectus excavatum and chicken breast. grow. In addition, during the operation, the doctor needs to make two instrument incisions on both sides of the patient's chest wall, plus a speculum incision. A total of two or three incisi...

[0002] Pectus excavatum and chicken breast are congenital diseases, which not only affect the patient's respiratory system and cardiopulmonary system, but also hinder the patient's bone development and healthy growth. Minimally invasive surgery is often used to correct the corrective device into the chest. , most of the orthodontic devices in the prior art are single support plates, which are fixed at both ends. The existing problem is that the correction method of fixation at both ends will affect the bones to a certain extent for children with high incidence of pectus pectus excavatum and chicken breast. to grow

In addition, during the operation, the doctor needs to make two instrument incisions on both sides of the patient's chest wall, plus a speculum incision. A total of two or three incisions are required. The locking piece is installed, resulting in many incisions, a large trauma area, and a strong foreign body sensation in the wound, which additionally increases the pain of the patient
