Subcutaneous expansion forceps
By designing subcutaneous expansion forceps with folded line articulation segments, the problem of existing hemostasis forceps causing the incision expansion during subcutaneous expansion is solved, and the stability and shrinkability of maintaining the width near the articulation shaft in minimally invasive surgery is achieved.

AI Technical Summary
Technical Problem
When existing hemostasis forceps are expanded subcutaneously, as the forceps are opened, the width near the hinge position increases, resulting in the incision being expanded and the minimally invasive surgical target cannot be achieved.
Method used
A subcutaneous expansion forceps are designed, and the articulated sections are in a fold-line shape. Through the groove design of the first and tail sections, when the forceps are opened, the width near the articulated shaft is reduced to avoid the incision being expanded.
Benefits of technology
During the subcutaneous expansion process, the width near the articulation shaft is kept unchanged or even reduced, thus achieving the goal of minimally invasive surgery and avoiding unnecessary expansion of the incision.

Abstract
The subcutaneous expansion forceps comprise two forceps bodies, each forceps body comprises a forceps head section, a hinge section and a forceps handle section which are sequentially connected, and the hinge sections of the two forceps bodies are hinged through a hinge shaft. The hinged section comprises a head section and a tail section, the head section is located on the side, close to the plier head section, of the hinged shaft, and the tail section is located on the side, close to the plier handles, of the hinged shaft. The side, provided with the clamp teeth, of the clamp body is a first side, and the side opposite to the first side is a second side. The second side of the head section is provided with a head section groove, and the first side of the tail section is provided with a tail section groove, so that the whole hinge section is in a broken line shape. When the subcutaneous expansion forceps are not opened, at least part of the head section groove of one head section is covered by the other head section, and at least part of the tail section groove of one tail section is covered by the other tail section. Compared with the prior art, when the subcutaneous expansion forceps are opened, the part near the hinged position is not expanded but is reduced to a certain extent, so that an incision is not expanded correspondingly, and the purpose of minimally invasive surgery is achieved.
