Description

Automatic traction device

Technical Field

The utility model relates to the field of medical equipment, more specifically relates to an automatic traction device for surgical operation.

Background

Retractors are one of the tools commonly used in surgery, through which tissue can be retracted and fixed to fully expose the surgical field. For example, in thyroid gland and cervical lymph node cleaning operation, the region of the operation must be exposed by pulling apart the cervical muscle group (e.g., zona, sternocleidomastoid muscle, etc.), and the subsequent surgical operation of thyroid gland requires suture, wire retractor, auxiliary grasping arm, etc. to complete the retraction of the cervical zonal muscle group, which makes the adjustment of the operation space difficult. At present, in the conventional operation of the thyroid gland open neck incision, the operation process is relatively standardized, and most operators adopt a neck middle-low position transverse collar type incision (a position of 2cm on a shoulder pad in a supine way and an incision on a sternum), the incision is small, and the requirement on the exposed operation visual field is high.

Surgical retractors (also known as retractor hooks) are commonly used in the prior art to enlarge the surgical field and expose the operating field. The shape of the retractor is different according to different use requirements, and the retractor is integrally divided into a manual type and an automatic type. When the manual retractor is used, an assistant is required to pull by hands, the strength is difficult to grasp, and the labor force is increased; often the assistant is positioned on the head side of the patient, and also affects the operation of the operator to some extent, and also affects the observation of the patient by the anaesthetist. The automatic retractor mostly adopts a stainless steel multi-piece structure which is combined and connected through a hinge, and the retractor is connected with the handle through a steel wire traction to control the opening and closing actions of the retractor so as to realize the tissue traction function. However, such retractors have more parts and complicated construction, which increases the burden of the operator; moreover, the tractor has a complex structure, not only is the production cost higher, but also is inconvenient to clean after the operation, is difficult to reach the sanitary standard, and increases the operation risk.
