Extravascular protection support

Abstract

The invention discloses an extravascular protection support which comprises a roll booster, a hollow protection tube and a hollow separator. The roll booster, the hollow protection tube and the hollow separator are sequentially arranged, a protection gap which is parallel to the central axis of the protection tube and penetrates through the two ends of the protection tube is formed in the side wall of the protection tube, a separation gap penetrating through the two ends of the separator is formed in the side wall of the separator, and the protection gap and the separation gap are centrally and linearly arranged. The separator and the protection tube are arranged, when the support is used, after the arteria carotis communis bifureation is separated through the submandibular incision, the internal carotid is exposed out, the internal carotid is sequentially wrapped by the separator and the protection tube, the separation gap and the protection gap are towards the outer side, the closed walls are towards the inner side, and exactly face the surgical operation direction, surgeons can fully and boldly remove diseased tissue in the operation, the accident that the internal carotid is accidentally injured, and the massive haemorrhage happens can be avoided, and the surgical treatment is improved.

Description

technical field [0001] The present invention relates to the field of medical devices, and more specifically relates to a device for protecting blood vessels, especially for patients with local recurrence of nasopharyngeal carcinoma after radiotherapy, a blood vessel for protecting the internal carotid artery during surgical treatment Outer protective bracket. Background technique [0002] For patients with simple nasopharyngeal residual or recurrent nasopharyngeal carcinoma after radiotherapy, the only effective rescue treatments are radiotherapy and surgery. Radiation sequelae are severe. Surgical treatment can directly remove radiotherapy-insensitive lesions and avoid radiation damage. It is a better choice for patients with locally failed nasopharyngeal carcinoma after radiotherapy. Studies have shown that in the case of the same recurrence and restaging, the curative effect of surgical treatment is equal to or even higher than that of NPC patients. better than radiatio...

AI Technical Summary

Problems solved by technology

Although a stent-graft can be implanted through interventional therapy to repair the damaged internal carotid artery, this kind of stent is not only expensive, but also requires specialized interventional physicians and surgical equipment, and the operation is complicated. Prevention of rupture of the internal carotid artery during surgery does not belong to the category of vascular protection devices
