Description

Retractor for general surgery department operation

Technical Field

The invention relates to the technical field of retractors, in particular to a retractor for general surgery operations.

Background

In a surgical operation, after skin muscles are cut open, the skin muscles are respectively pulled to two sides by using a draw hook, so that the middle operation visual field is exposed.

In order to solve the existing problems, a retractor is used for fixing a surgical draw hook during the abdominal operation such as liver resection, pancreas duodenectomy, splenectomy and mench vein amputation. Although the existing surgical draw hooks have replaced the manual drawing of the previous second assistant and the third assistant, certain time and physical strength are saved, but certain defects still exist in the existing surgical draw hooks, such as fixed size and shape of the draw hooks, and limitation of adjustment of the angle and the direction of the retractor by a main surgeon according to different surgical needs and surgical fields, so that the surgical fields are exposed in a limited way and are inconvenient to adjust; the partial retractors have more components and larger frames, not only have complex installation but also obstruct operation, and bring certain troubles to operators. Also, since a well exposed surgical field is essential to any surgical procedure during surgery. The hand type retractor of the exposure instrument used in the operation is the most commonly used, when the retractor is used for drawing, because the retractor and the edge of an operation incision are mostly in point contact, generally, each retractor can only draw a triangular operation visual field, and a wider operation visual field is achieved. There are various specifications of different shapes and sizes, and the proper retractor can be selected according to the operation requirement.

For example, the traction retractor for the general surgery department with the publication number of CN113208671A comprises a retractor and a retractor detachably fixed on the retractor, the retractor is annularly and uniformly distributed on the retractor, stabilizing upright columns are arranged at two ends of the retractor, the retractor is detachably fixed on the stabilizing upright columns, a rotating ring is sleeved in the retractor and rotatably arranged in the retractor, a locking mechanism for the rotating ring is arranged on the retractor, a sliding seat is arranged on the side wall, away from the retractor, of the rotating ring, the sliding seat is slidably arranged on the inner side of the rotating ring, a retractor fixing plate is arranged at the top of the sliding seat, a connecting through hole is formed in the retractor, a connecting threaded hole is formed in the retractor fixing plate, the retractor penetrates through the connecting through hole through a bolt and is in threaded connection with the connecting threaded hole, the invention has simple structure and convenient processing, and is suitable for large-scale popularization and use.

Above-mentioned general surgery department operation is with pulling the drag hook can not laminate the human shape that changes the retractor when using, so can restrict the use of pulling the drag hook because of the angle problem when running into needs armpit or joint department, use to pull the drag hook and need the multiunit to strut patient's wound moreover, not only can cause the strain to patient's wound, the position that needs continuous adjustment drag hook during the use moreover finds suitable angle, can cause the secondary damage to the patient, consequently, this application provides a retractor for general surgery department operation and satisfies the demand.
