Problems solved by technology

[0003] However, when the existing retractor is pulling the surgical incision, it needs to be manually pulled, resulting in different pulling speeds, and can not control the distance well, resulting in the large or small incision, which is not conducive to the operation, and Hand-held retractors are required, which increases the workload of medical nurses during the operation, which in turn causes the doctor to be unable to handle other operations, reducing work efficiency, and retractors are generally not installed on the operating table, resulting in the need for surgical instruments when in use search in, reducing the search efficiency

Abstract

The retractor with the thyroid retractor head structure comprises a support body, a moving assembly, a lifting assembly and a mounting assembly, the moving assembly is fixed to the inner wall of the top end of the support body, the lifting assembly is fixed to the outer wall of the top end of the support body, and the mounting assembly is fixed to the outer wall of the bottom end of the support body; the moving assembly comprises a lifting groove, an air cylinder, a lifting block, a first motor, a first gear, a second gear, first sliding grooves, a T-shaped sliding plate, a first rack and a second rack. The first sliding grooves are formed in the inner walls of the two sides of the support body. When the surgical incision is pulled open, the surgical incision can be automatically pulled, manual pulling is not needed, and in the pulling process, the pulling speed can be changed, so that it is ensured that the incision reaches the specified size, and the surgical effect is improved; the retractor can be automatically lifted without being manually held by hand, so that the workload of medical care is reduced.

Description

technical field [0001] The invention belongs to the technical field of retractors, in particular to a retractor with a thyroid retractor head structure. Background technique [0002] Retractor, also known as retractor, is used to retract tissue, reveal the scope of surgery, and facilitate exploration and operation. It can be divided into two types: hand-held retractors and automatic retractors; there are various shapes and sizes of specifications, and the appropriate one can be selected according to the needs of surgery. The retractor with thyroid retractor head structure is also one of them. [0003] However, when the existing retractor is used to open the surgical incision, it needs to be manually pulled, resulting in different pulling speeds and inability to control the pulling distance well, resulting in large or small incisions, which is not conducive to the operation. The retractor needs to be hand-held, which increases the workload of nursing during the operation, wh...
