The esophageal tumor marking device comprises a marking clamp, wherein the marking clamp comprises a first clamping arm 1 and a second clamping arm 2. One end of the first clamping arm 1 is connected with one end of the second clamping arm 2, the other end of the first clamping arm 1 and the other end of the second clamping arm 2 are free ends, and the two free ends can move relatively to realize the opening or closing movement of the marking clamp.

The clamping surface of the marking clip is provided with a fixation structure, the fixation structure is used for firmly fixing the marking clip on the outer surface of tumor cells after the marking clip is closed and can not fall off due to tumor displacement or swallowing action of a patient, the opening angle α of the marking clip is set to be an acute angle, the occupied space of the marking clip is reduced, and discomfort of the patient is reduced in the process of entering the esophagus.

The utility model provides an esophagus tumour mark device's the process of placing, using and retrieving as follows:

the marking clamp extends into a tumor focus part of the esophagus from the oral cavity through instruments such as a titanium clamp, after the tumor focus part is reached, the first clamping arm 1 and the second clamping arm 2 are closed through the instruments and clamped outside tumor cells, in order to mark the boundary of the tumor more accurately, the marking clamp is respectively clamped on the upper boundary and the lower boundary of the tumor cells, and due to the fact that the clamping surface of the marking clamp is provided with the fixation structure, the marking clamp can be firmly fixed outside the tumor after being closed.

The marking clamp is made of titanium alloy materials, after the marking clamp is clamped outside the esophageal tumor part, the marking clamp can shield signals sent by a radiotherapy instrument to form shadows during treatment, and the tumor radiotherapy instrument can dynamically track the position of the marking clamp so as to accurately position the tumor part. After the radiotherapy treatment is finished, an instrument such as a titanium clamp is used for stretching into the position of the marking clip from the oral cavity, and the marking clip is opened and taken out for recycling.

The utility model provides an esophagus tumour mark device compares with prior art, presss from both sides the pathological change position that stretches into the esophagus from the oral cavity with the mark with the apparatus to press from both sides the mark and press from both sides the outside at tumour tissue, because the clamping face that the mark pressed from both sides is the medial surface of first arm lock and second arm lock all is equipped with the set structure promptly, can prevent that the mark presss from both sides from droing from tumour tissue. In the radiotherapy process, the emptying equipment can dynamically identify and position the marking clamp, so that the part where the tumor is located can be accurately positioned. After the radiotherapy is finished, the marking clamp is opened by an instrument, the tumor tissue can be taken out and recovered by separating from the outside, the recovery process is convenient, and the damage to the tumor or other esophagus tissues in the recovery process is avoided.
