Problems solved by technology

However, it is best to complete the free flap operation consecutively, otherwise the operation time will be prolonged
In addition, it is not easy for the assistant to operate multiple towel forceps or hemostatic forceps to grasp the pulling force. If a certain area is pulled with excessive force, it will cause skin flap necrosis

Abstract

The invention discloses an assembly type skin retractor and belongs to surgical operating instruments. The assembly type skin retractor comprises an arc handle and a plurality of retractors connected with the handle, wherein a slide groove is arranged on the handle from bottom to top from the lower surface of the handle, two positioning strips are arranged on two lateral walls in the slide groove along the arc surface direction, and a plurality of clamping openings are arranged on the upper surfaces of the positioning strips. Positioning blocks sliding on the positioning strips are arranged at the upper ends of the retractors, and positioning protrusions capable of being clamped in the clamping openings are arranged on the two sides of the lower ends of the positioning blocks. The assembly type skin retractor is novel and flexible in structural design. The retractors with corresponding quantity can be installed according to patient needs and operation situations, burden of assistants is reduced, and only one assistant is needed. Additionally, optimal traction force is ensured, constant tension is kept, quick and continuous operations can be ensured, and possibility of complication is reduced.

Description

Technical field [0001] The invention relates to a surgical tool, in particular to a combined skin retractor for breast cancer skin flap free surgery. Background technique [0002] In surgical operations, the surgeon often has to be equipped with an assistant to help the skin or tissue near the incision to turn out. Especially in breast cancer surgery, the skin flap is stripped for sharp anatomy, and the skin flap needs to maintain a certain tension to benefit the surgeon For the operation, at present, 2~3 assistants use towel clamps or vascular clamps to clamp the flaps and then unfold and maintain uniform force pulling. Each assistant needs to pull 2 ​​or more towel clamps or vascular clamps to complete the entire skin. The liberation of the petals requires alternates between assistants to complete. However, the free flap operation should be done consecutively, otherwise the operation time will be prolonged. In addition, it is not easy to grasp the pulling force of multiple to...
