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 operation tool, in particular to a modular skin retractor for breast cancer skin flap free operation. Background technique

[0002] In surgical operations, the chief surgeon often has to be equipped with an assistant who is responsible for everting the skin or tissue near the incision, especially in breast cancer operations, where skin flaps are peeled off for sharp dissection, and the flap needs to be maintained at a certain tension to benefit the surgeon. For the operation, 2 to 3 assistants currently use towel forceps or vascular forceps to clamp the skin flap and then stretch it evenly and forcefully. Each assistant needs to pull 2 ​​or more towel forceps or vascular forceps to complete the entire skin flap. The dissociation of the flap requires alternating between assistants to complete. However, it is best to complete the free flap operation continuously, otherwise the operation time will be prolonged. In add...
