Abstract

The invention discloses a dilator for thyroid resection through oral vestibule combined with subchin approach, which comprises an adjusting bracket suitable for upward view of the head of a patient, and an expanding and supporting mechanism for exposing the oral vestibule and neck operation channel of the patient is slidably mounted on the adjusting bracket; stand columns of an adjusting support are symmetrically installed on the upper surface of a headrest plate, flexible rotating mechanisms are installed at the tops of the stand columns, the two ends of a rotating plate are connected with the rotating ends of the two flexible rotating mechanisms respectively, and a nipper is horizontally arranged and rotationally installed at the top of the rotating plate. The expanding mechanism comprises a hand-held part and expanding parts, the upper portion of the hand-held part is in sliding connection with the nipper, and the expanding parts are installed on the middle portion and the lower portion of the hand-held part. According to the distraction device, rapid distraction of an operation channel is facilitated, the operation time is saved, waste and consumption of energy of operation personnel are avoided, the distraction effect and stability of the operation channel are improved, the operation of the operation personnel is facilitated, the process and accuracy of resection operation are improved, and excessive secondary trauma to a patient is greatly avoided.

Description

Technical field [0001] The present invention relates to the technical field of surgical instruments, and more particularly to the inlet tamper-proof struts. Background technique [0002] Traditional thyroid surgery will have a very psychological burden due to a surgical scar (wound) in the patient's neck. With the continuous development of the cavity thyroid surgery, the surgical method of the cavity is selected, and the neck incision of about 10cm of the conventional surgery is reduced to 2 cm, and the surgical incision of usually in the neck can be changed to the chest preterm. The hidden position such as the lower or oral cavity opens three small holes to complete the surgery, and the patient who has a higher beauty requirement can choose the hyperoscopic thyroid surgery according to the condition. [0003] The thyroid resection of the junior quarter is more suitable for patients with smaller lips and has a beauty requirement; the wound is hidden in the mouth and the mouth, th...
