Guide skin expanding device and application thereof

Abstract

The invention provides a guide skin expanding device and application thereof. The device comprises a forceps body; the forceps body is of a forceps-shaped structure formed by hinging a left forceps arm and a right forceps arm through a pin shaft after the left forceps arm and the right forceps arm are crossed. The front end face of the left forceps arm is connected with a left limb extending forwards, the front end face of the right forceps arm is connected with a right limb extending forwards, and the free end of the left limb and the free end of the right limb are overlapped to form a guidehead used for penetrating into a skin opening and allowing a guide wire to penetrate through. The forceps body has an open state and a closed state. The guide skin expanding device is divided into a guide section, an expanding section and a handheld section, wherein the guide section guides a guide head, on one hand, the guide wire can penetrate through the guide head, namely, the guide wire is guided, and on the other hand, the guide head can penetrate into the skin opening, and preparation is made for next-step expanding; the expanding section is composed of a left limb and a right limb, after the guide head penetrates into the skin opening, the left limb and the right limb are separated, the jaw is opened, the jaw can expand the dilated skin opening, an intubation tube can enter the blood vessel from the dilated skin opening, and use and popularization are convenient.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a guiding skin expansion device and its application, and is especially suitable for ECMO intubation. Background technique [0002] The current intubation techniques mainly include three schemes: percutaneous puncture, semi-open surgically guided percutaneous puncture, and open surgical incision and catheterization. Directly into the blood vessel to achieve the purpose of catheterization. [0003] However, whether it is gradual skin expansion or violent intubation, there are problems such as single skin expansion scheme, complicated tools, complicated steps, and difficulty in mastering. Especially in gradual skin expansion, the sheath can not be shaped and has no physiological Curvature, resulting in subcutaneous discount and difficult access to blood vessels, even if it enters blood vessels, it may puncture blood vessels, damage blood vessels, and even cause blood vessel rupture a...

Problems solved by technology

[0003] However, whether it is gradual skin expansion or violent intubation, there are problems such as single skin expansion scheme, complicated tools, complicated steps, and difficulty in mastering. Especially in gradual skin expansion, the sheath can not be shaped and has no physiological Curvature, resulting in subcutaneous discount and difficult access to blood vessels, even if it enters blood vessels, it may puncture blood vessels, damage blood vessels, and even cause blood vessel rupture and hematoma formation, so there is a high risk, and at the same time, multiple dilators are required for gradual skin expansion , leading to higher costs and difficult promotion and use
