Breastbone drag hook

Abstract

The invention discloses a breastbone drag hook. The breastbone drag hook comprises a base, an electric telescopic rod, a horizontal rod and drag hooks, wherein the lower end part of the electric telescopic rod is vertically fixed to the base, and a rotating shaft and a supporting plate are arranged at the upper end of the electric telescopic rod; an inserting hole which is inserted into the rotating shaft is formed in one end of the horizontal rod; the bottom of the horizontal rod is supported by the supporting plate; the drag hooks are connected with the horizontal rod; each drag hook comprises a connecting rod and a drawing claw; each drawing claw is mounted on the corresponding connecting rod, and is used for drawing the breastbone of a human body; a sterile disposable sleeve sleeves each drawing claw; and a plurality of gas storing bags which can be cut by a scalpel are arranged on the surface which is in contact with the breastbone of the human body, of the sleeve. According to the breastbone drag hook disclosed by the invention, during an operation, the gas storing bags which are pressed on blood vessels or nerves are cut by the scalpel, so that a sunken part is formed in thelocation of the breastbone drag hook, the situation that the blood vessels or the nerves are pressed is avoided; the horizontal rod does not cross an operating table, and the telescopic rod is also not arranged on the standing side of a doctor, so that the operation view field is greatly enlarged; and materials of components including the telescopic rod, the horizontal rod, the drawing claws andthe like can resist high temperature, so that the high-temperature sterilization condition of operation instruments is met, and the risk of operation infection is reduced.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a sternum retractor. Background technique [0002] In the operation of the thoracic cavity, it is necessary to use the retractor to pull up the human sternum so that there is more space in the thoracic cavity for the doctor to perform the operation. However, in the existing retractor device, the sternum of the human body is directly pulled, and it will be oppressed when encountering surrounding blood vessels or nerves. The hook claws cannot be deformed at the blood vessels or nerves, so that the hook claws will greatly compress the blood vessels or nerves. Secondly, in the existing hook devices, in order to balance the horizontal rod, most of the support structures are designed on both sides of the horizontal rod, that is, two telescopic rods support the two ends of the horizontal rod, and the hook is located in the middle of the horizontal rod to hang down. Sternum, a...

Problems solved by technology

However, in the existing retractor device, the sternum of the human body is directly pulled, and it will be oppressed when encountering surrounding blood vessels or nerves. The hook claws cannot be deformed at the blood vessels or nerves, so that the hook claws will greatly compress the blood vessels or nerves.

Secondly, in the existing hook devices, in order to balance the horizontal rod, most of the support structures are designed on both sides of the horizontal rod, that is, two telescopic rods support the two ends of the horizontal rod, and the hook is located in the middle of the horizontal rod to hang down. The sternum, and clinically, doctors are mostly standing on the left side of the patient when performing thoracic surgery. Whether the existing device is a horizontal rod across the operating table, or a telescopic rod is installed on the side where the doctor stands, it will cause the doctor's surgical field of vision to be blocked.
