Breast skin flap arc draw hook with movable hook harrow

Abstract

The invention belongs to the field of medical apparatus and instruments, and discloses a breast skin flap arc draw hook with a movable hook harrow. The draw hook comprises an arc framework (1), sliding blocks (2), a movable hook harrow (3), and a pressing screw (4), wherein the arc framework is sleeved with a plurality of sliding blocks; two sides at which the arc edges of the sliding blocks and the arc framework correspond to each other, are provided with a movable hook harrow trepan boring (5) respectively; a movable hook harrow handle part (6) is inserted in the movable hook harrow trepan boring and is between the arc framework and the top parts of the sliding blocks; a movable hook harrow tooth part (7) points to the centre of a circle of the arc framework; and the top parts of the sliding blocks are provided with pressing screw holes (9); and tightened pressing screws (4) can simultaneously enable the sliding blocks and the moveable hook hallow handle part to be pressed and fixed on the arc framework. The invention has the advantages that the draw hook has simple structure, is flexible in operation and accurate in allocation, saves labor, and is suitable for stretching operation of skin flap cutting in a breast operation in particular to a breast cancer radical operation process.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to a breast flap arc pull hook with a movable hook rake. Background technique [0002] At present, breast cancer is a frequently-occurring disease and a common disease in my country and the world. The principle of breast cancer treatment is comprehensive treatment based on surgery. Clinically, the main surgical method used in breast cancer surgery is radical modified radical mastectomy. In this operation, the operation involving skin flap incision often takes more than half an hour, and most of the time, one person's hands plus another person's single hand are required for the retractor specially used for the skin flap. And the work of drag hook is a kind of mechanical work with low technical content and high physical strength requirement that needs to maintain continuous pulling force for a long time. It is not difficult to understand that at present, a big contradiction in the radi...

AI Technical Summary

Problems solved by technology

It is not difficult to understand that at present, a big contradiction in the radical operation of breast cancer is that many times, the manpower of doctors seems to be insufficient; at the same time, too many manpower is assigned to the posts of mechanical flap hooks, some of them are overqualified and useless. Show the worth of a surgeon

[0003] In the prior art, there are many retractor devices that help reveal the incision or the surgical field of view, but looking at the existing devices and existing patents, there are still obvious shortcomings: some need to be fixed on the bed frame of the operating bed, which is inconvenient to operate ; Some are large in size, suitable for deep exposure such as the abdominal cavity; some have obvious specialty features, such as vein retractors, nerve retractors

Therefore, although these drag hooks have the advantage of saving manpower, they also bring the disadvantage of not being flexible enough to adjust

In addition, since the operation involving the breast flap is performed on one side of the flap instead of alternately on both sides, the ring retractor occupies both sides of the operation range, which will hinder the operation and interfere with the line of sight

[0005] At present, there is no report on retractors that can be flexibly used to pull skin flaps in breast surgery
