Subcutaneous incision expanding forceps

Abstract

The invention relates to the technical field of medical instruments, and discloses subcutaneous incision expanding forceps. Wherein the subcutaneous incision expanding forceps comprise two expanding handles and two expanding arms, and the two expanding handles can be unfolded or combined relative to the movable joint; the two expanding arms are connected with the two expanding handles in a one-to-one correspondence mode, each expanding arm comprises a first section connected with the expanding arm and a second section connected with the first section, a first preset included angle is formed between the second section and the inner side of the first section, a hook is arranged at the end, away from the first section, of the second section, and the hook can expand the subcutaneous incision when the two expanding handles are unfolded or combined; a second preset included angle is formed between the plane where the second section is located and the plane where the expanding handle is located. The first preset included angle is formed between the first section and the second section of the expanding arm, so that an enough operation space is provided for an operator above a subcutaneous incision position; and a second preset included angle is formed between the plane where the second section is located and the plane where the expanding handle is located, so that interference of the subcutaneous incision expanding forceps to other surgical instruments during intraoperative operation is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a subcutaneous incision expanding forceps. Background technique [0002] Common subcutaneous tumors include lipoma, sebaceous cyst, fibroma, cavernous hemangioma, etc., which not only affect the appearance, but also cause compression symptoms or skin damage due to frequent friction. There are sebaceous gland openings on the skin surface, which can easily cause repeated infection and form abscesses; in addition, breast fibroids have a certain probability of malignant transformation. Therefore, surgical excision is required in the above-mentioned situations. [0003] At present, the surgical field exposure instruments used for subcutaneous tumor resection are mainly thyroid retractors, forceps and suction devices. However, most of them have problems such as complex structure, small field of view, and inconvenient operation. [0004] Therefore, it is necessary to provide ...
