Problems solved by technology
[0002] Before the present invention, the current deep horizontal suspension suture operation was difficult because of the narrow operating space for deep needle entry, needle exit and control of needle entry and exit points, and poor field of vision, which made simple suspension suture operation very difficult
In order to make the operation as smooth as possible, pulling through the incision is usually used to obtain a limited operating space, but it can only be done barely, and the pulling incision will inevitably damage the surrounding tissues, which will easily cause deep tissue bleeding and is difficult to stop bleeding. In order to completely stop bleeding And to achieve the ideal suspension effect, sometimes even need to extend the cut to complete

Embodiment Construction
[0011] Such as figure 1 , figure 2 Shown:
[0012] The present invention consists of a guide ring 1, a central shaft 3 and a handle 2; the guide ring 1 and the central shaft 3 are connected as one, and the central shaft 3 has teeth on both sides to form a rack, which is connected with the ratchet 5; Both sides of the handle 2 are provided with ratchets 5, grooves are formed on both sides of the handle 2, and the ratchets 5 are arranged in the grooves;
[0013] The material of the guide ring 1 needs to have sufficient toughness and hardness, and memory alloy can be selected, which can meet the requirement of its adjustable size, and its structure should be smooth and round without cutting damage to surrounding tissues.
[0014] The application process of the present invention is illustrated by taking superficial temporal fascia suspension in temporal wrinkle surgery as an example:
[0015] Place the guide ring 1 on the expected hanging part of the corner of the eye through ...

The invention relates to a deep horizontal suspension suture guide. The deep horizontal suspension suture guide has a structure that ratchets are arranged in grooves on two sides of a handle respectively and contacted and connected with racks on two sides of a centre shaft, and the front end of the centre shaft is connected with a guide ring made of a flexible material. The deep horizontal suspension suture guide overcomes the drawbacks in the prior deep horizontal suspension suture operation such as high difficulty, narrow space, limited vision, injuries to tissues surrounding the cut caused by drawing a cut to obtain limited operation space, difficult stanching of bleeding tissues and failure in achieving ideal suspension effect. The invention provides a reliable auxiliary appliance for deep horizontal suspension suture, which provides ample operation space, causes less injuries to the tissues, and is extremely convenient, simple and easy in operation, applicable to various cuts, capable of achieving satisfactory effect, simple in structure, low in cost and strong in professional.
