Description

Surgical clinical operation is with leading out device

Technical Field

The invention relates to the technical field of medical treatment, in particular to a retractor for surgical clinical operation.

Background

Surgery is a subject of modern medicine and is primarily concerned with the treatment of patients by surgical methods to eradicate the patient. Surgery, like all clinical medicine, requires knowledge of the definition, etiology, presentation, diagnosis, staging, treatment, prognosis of a disease, and places more emphasis on surgical-related problems such as open-surgical indications, pre-operative assessment and care, surgical skills and procedures, post-operative care, surgical complications and prognosis.

In the surgical clinical operation, when the skull or spine of a patient is operated, a retractor is generally required to be adopted to retract the skin and muscle tissues of the patient so as to provide an operation space, but in the current common operation retractor, the occupied larger space of the retractor affects the exposure of an operation field when the operation is performed, in the neurosurgery operation, the good effective and sufficient exposure of the operation field is one of the key conditions for the successful performance of the whole operation, in order to improve the exposure of the operation field, the retractor can be used for two aspects, namely, the size of a traction opening is increased, and the size of the occupied space when the retractor is pulled is reduced.

Traditional retractor leads to the edge of a knife to draw unstably owing to adopt two point type to draw owing to mostly to bring great misery for the patient, medical personnel are also not good at the field of vision degree when carrying out the operation to it simultaneously, and current retractor can only simply draw moreover and lead to being difficult to carry out safe processing to patient's wound.

Therefore, there is a need to provide a new retractor device for surgical clinical operation to solve the above technical problems.
