Abstract
The utility model discloses an improved nerve root draw hook, which comprises a flat hook body. A draw hook is arranged at one end of the hook body, a handle is arranged at the other end of the hook body, a suction tube is arranged on each side of the flat hook body, the suction holes of the suction tube are distributed on the two sides of the draw hook, the outlet holes of the suction tube converge at the tail end of the suction tube to form one hole which is connected with a suction pressure generator, a cold-light source passage is arranged inside the hook body, and the opening of the cold-light source passage is positioned on the front face of the draw hook. Due to the two suction holes arranged on the two sides of the draw hook, the seeped blood and fluid on the surgical wound surface can be well sucked; and due to the cold-light source arranged on the draw hook, lighting is convenient, thereby facilitating surgical operation.
Description
Technical field
This utility model relates to a kind of clinical operation assistive device, especially relates to the nerve root retractor that uses when a kind of canalis spinalis is performed the operation.
Background technology
Clinically, the canalis spinalis disc removal operation of performing the operation especially, be characterized in that operative site is dark, surgical field of view is little, surgical field of view is unintelligible, for making the art open country clear, at present, generally take to broaden one's vision with nerve root retractor, and in time absorb sepage and oozing of blood on the surgical wound surface with suction pump, original so just very little surgical field of view adds nerve root retractor and suction catheter comes into view simultaneously, has more influenced the operation of operation, for addressing this problem, occurred a kind of nerve root retractor at present, suction pump and nerve root retractor have been made one, simplified operating performance with suction pump, but still there are two problems: the one, thin and skewness attracts effect undesirable because of suction catheter; The 2nd, the surgical field of view deep is still relatively darker.
Summary of the invention
The purpose of this utility model is exactly for solving the problem that above nerve root retractor exists, a kind of improved nerve root retractor is provided, and it has suction catheter and is evenly distributed, and attracts area big, simultaneously the characteristics that can throw light on to the art open country.
The purpose of this utility model is achieved through the following technical solutions, this improved nerve root retractor comprises a flat coupler body, one end of described coupler body is a drag hook, the other end is a handle, the both sides of described flat coupler body are provided with suction catheter, and the suction pore size distribution of described suction catheter is in the both sides of drag hook, and the end at suction catheter of portalling of described suction catheter merges into a hole and links to each other with negtive-pressure implement, one cold light source passage is arranged in the described coupler body, and the opening of its cold light source passage is positioned at the front of drag hook.
During use, should put on the wild wound surface of art by improved nerve root retractor, utilize cold light source to throw light on, utilize the open art of drag hook open country, the suction hole that is positioned at the suction catheter of drag hook both sides can be with the oozing of blood sepage sucking-off on the art open country.
The beneficial effects of the utility model: inhale the hole owing to be provided with two at the drag hook place, can sop up the oozing of blood sepage on the wild wound surface of art preferably, the cold light source that is provided with owing on drag hook can throw light on the operation that helps performing the operation easily.
