Medical thyroid surgery supporting frame

Abstract

A bottom plate can be connected with an operating bed, five supporting mechanisms are all installed on the upper side of the bottom plate, a first pad, a second pad and a headrest pad are all made of silica gel materials, inner cavities of the first pad, the second pad and the headrest pad are all filled with low-melting-point alloy and are provided with heat exchange pipes, a first electric cylinder controls lifting and positioning of the first pad, and a second electric cylinder controls lifting and positioning of the second pad. The second electric cylinder controls lifting and positioning of the second cushion, the third supporting mechanism and the fourth supporting mechanism are the same as the second supporting mechanism in structure and installation mode and can move along with rotation of the head and the neck of the patient, the headrest cushion and the arc plate support form a rotating pair through an arc plate, and the motor can drive the headrest cushion to rotate. A third electric cylinder controls lifting and positioning of the headrest cushion, a temperature control system can achieve phase state change of low-melting-point alloy in the five cushions, the five cushions can be attached and supported according to the curved surface shape of the lower side of the head and neck of the patient, and the head and neck of the patient can be effectively fixed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical thyroid surgery support frame. Background technique [0002] The thyroid gland is located under the thyroid cartilage on both sides of the trachea in the neck. It is a very important endocrine organ in the human body. The main function of the thyroid gland is to synthesize, store and secrete thyroid hormones. The main function of thyroid hormones is to promote the body's metabolism and maintain the normal growth and development of the body. It has a greater impact on the development of the skeleton and nervous system; in clinical practice, goiter and thyroid tumors often need to be treated by surgery. Due to the special location of the thyroid gland, it is necessary to adopt a supine position with the neck hyperextended during the operation , the specific means usually adopted is to place a pillow on the lower side of the patient's neck to elevate the neck and t...

Problems solved by technology

[0003] Under the existing technical conditions, silicone pads are usually used to raise the patient's neck. Due to the differences in the body shape of different patients, the length of the neck and the bending limit are not the same. Therefore, the simple neck pad cannot fully adapt to the needs of various patients; and because the thyroid gland is shaped like a butterfly and is located on both sides of the trachea, the rotation angle of the patient's head will be adjusted during the operation according to the condition of the patient, so that the doctor can The lesion can be seen clearly, but the doctor can only rely on the manual operation when turning the patient's head. Not only is the rotation angle difficult to control precisely, but also the operation efficiency is reduced. In addition, there are seven cervical vertebrae in the human body, and the first cervical vertebra is called the atlas , the second cervical vertebra is called the axis, the atlas and the axis are collectively called the upper cervical vertebra, and the third to seventh cervical vertebra are collectively called the lower cervical vertebra, and the left and right rotation of the human head mainly occurs in the upper cervical vertebra. When the patient’s head is turned left and right in the extended supine position, the skin tissue corresponding to the underside of the patient’s atlas and axis will dry rub against the silicone pad, and the soft tissue will be damaged under long-term dislocation static pressure, which will increase the patient’s In addition, both the axis and the lower cervical spine have spinous processes backward. When the pillow raises the neck, the position of the spinous processes will be mainly compressed. Long-term static pressure will also increase the soft tissue damage of the patient's back neck. Therefore, a A support frame for thyroid surgery that can adapt to different patient sizes, accurately rotate the patient's head, and avoid soft tissue damage is of obvious interest
