Problems solved by technology
At present, some special instruments for endoscopy have been developed, however, compared with other endoscopic treatment techniques, it is still difficult to operate
In current operations, mesh baskets and five-jaw pliers are commonly used to pull and drag tissues. During surgical operations, the tool action mechanism is still controlled by the lens, and cannot change the operating direction by itself. It often requires repeated advances and retreats of the lens to operate. , the surgical operation is more difficult, and the field of view is limited

Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings.
[0024] Such as Figure 1 to Figure 4 The multi-directional adjustable draw hook shown includes a handle part 1, a hose part 2 connected to the handle part 1, a draw hook part 3 connected to the end of the hose part 2, and the draw hook part 3 is connected and arranged on the handle part 1 The push rod part 12 and the hook part 3 are connected to the power supply, wherein the hose part 2 is a solid hose, and two pairs of guide wires 4 are passed through the hose part 2, and the guide wires 4 are parallel to each other. There are holes for each guide wire 4 to pass through. One end of each guide wire 4 is fixed to the end of the hose part 2 . The handle part 1 is provided with two coaxial rotating disks 5, and each pair of guide wires 4 passes through the hose part 2 and is connected to a rotating disk 5 respectively. The central axes of the hose parts 2 intersect and...

The invention discloses a multi-directional adjustable drag hook.The drag hook comprises a handle part, a hose part connected with the handle part, and a drag hook part arranged at the end of the hose part.The drag hook part is connected with a push rod part.Two pairs of guide wires penetrate into the hose part.One end of each guide wire is fixed to one end of the hose part.Two rotary plates are arranged in the handle part.The guide wires penetrate through the hose parts and are both connected with one rotary plate.The planes where the two pairs of guide wires in the hose part are located are crossed in the center axis of the hose part and perpendicular to each other.When the rotary plates rotate in different directions, the guide wires can be dragged respectively to drive the ends of a hose to bend in different directions along with the drag hook part.The hose close to the end of the drag hook part is driven to bend in different directions.When the multi-directional adjustable drag hook is used for EMR, ESD or other complex operation in endoscopic surgery, and a lens is only used for observation, the drag hook can control the direction and grasp and drag tissue, so that operation difficult is reduced, and operation risks can be reduced.
Description
technical field [0001] The invention relates to the field of medical equipment, in particular to a multidirectional adjustable drag hook. Background technique [0002] Endoscopy has been born for more than 50 years, and has gone through the stages from disease diagnosis to disease treatment. The treatment of some digestive diseases has been very effective and reliable, and has even become the first choice for the treatment of some diseases. In recent years, with the development of endoscopic biopsy, EMR (endoscopic mucosal resection), ESD (endoscopic submucosal dissection) technology, the treatment of polyps and early cancers of the digestive tract is gradually becoming a preferred diagnosis and treatment. means. In particular, it plays a key role in the detection, diagnosis and resection of early cancer. At present, some special instruments under endoscopy have been developed. However, compared with other endoscopic treatment techniques, it is still difficult to operate. ...
