no. 1 approach

[0037] The first embodiment of the present invention relates to a guiding skin expanding device, referring to figure 1 , it includes the pliers body 1, the pliers body 1 is a pliers-shaped structure hinged by the left pliers arm 2 and the right pliers arm 3 through a pin after crossing, the front end of the left pliers arm 2 is connected with a left Limb 4, the front end of the right forceps arm 3 is connected to a right limb 5 extending forward, the free end of the left limb 4 overlaps with the free end of the right limb 5 to form an opening for penetrating the skin and can be used for the guide wire to penetrate Seeker 6;

[0038] The pliers body 1 has two states, namely an open state and a closed state;

[0039] When the clamp body 1 is in the open state, such as figure 1 As shown, the left limb 4 and the right limb 5 are separated from each other, and the left pincer arm 2 and the right pincer arm 3 are separated from each other to form a jaw 7 that can expand the skin o...

no. 2 approach

[0056] This embodiment relates to a guiding skin expansion device, referring to figure 1 , it includes the pliers body 1, the pliers body 1 is a pliers-shaped structure hinged by the left pliers arm 2 and the right pliers arm 3 through a pin after crossing, the front end of the left pliers arm 2 is connected with a left Limb 4, the front end of the right forceps arm 3 is connected to a right limb 5 extending forward, the free end of the left limb 4 overlaps with the free end of the right limb 5 to form an opening for penetrating the skin and can be used for the guide wire to penetrate Seeker 6;

[0057] The pliers body 1 has two states, namely an open state and a closed state;

[0058] When the clamp body 1 is in the open state, such as figure 1 As shown, the left limb 4 and the right limb 5 are separated from each other, and the left pincer arm 2 and the right pincer arm 3 are separated from each other to form a jaw 7 that can expand the skin opening;

[0059] When the cla...

no. 3 approach

[0066] On the basis of the first embodiment or the second embodiment, refer to Figure 4 , the guide wire channel 8 is divided into two sections, which are respectively the front guide wire channel and the rear guide wire channel. The tubular channel formed by pairing bar-shaped grooves 10, the rear guide wire channel is composed of the bar-shaped grooves 10 opened on the inside of the forearm of the left forceps arm 2 and the bar-shaped grooves 10 opened on the inside of the forearm of the right forceps arm 3 tubular channel.

[0067] Such as figure 2 As shown, when the guide skin expansion device is in the closed state, the guide wire channel 8 is a closed lumen, which provides a channel for the guide wire and protects the guide wire from contacting with other machines; however, the guide wire channel 8 is not always closed state, when the guide skin expansion device is in the expanded state, the guide wire channel 8 is open, and it can be seen that it is composed of two ...

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...
