Abstract

The invention discloses an endovascular biopsy device. The endovascular biopsy device comprises a pair of biopsy forceps, a turn barrel, an angle regulation resetting mechanism, a sheath, a fixing bladder and a liquid filling catheter, wherein the biopsy forceps comprise a binding clip, a long arm and an operating handle; the long arm is arranged in a hollow chamber of the turn barrel; the bindingclip and the end head of the long arm connected with the binding clip penetrate through the outer wall of the turn barrel; the angle regulation resetting mechanism is hinged with the outer wall of the turn barrel and is in slip connection with the end head of the long arm; the sheath is in slip connection with the turn barrel; the fixing bladder is arranged above the binding clip; the liquid filling catheter is arranged in the hollow chamber of the turn barrel; the liquid filling catheter is connected with the fixing bladder; and the fixing bladder is connected with a conical head. By the endovascular biopsy device, a biopsy tissue of an intravascular space-occupying lesion is obtained by an interventional method, thereby enabling pathological diagnosis. The effect of early diagnosis is achieved while avoiding open surgical trauma. On the basis, the invention also provides a biopsy system.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intravascular biopsy device and a biopsy system. Background technique [0002] Diagnosis of intravascular space-occupying lesions is a difficult point in medicine. [0003] At present, in order to obtain pathological results under medical technology, open surgery is required, and the trauma is very large. If it is an inflammatory lesion, it will bring unnecessary damage to the patient. Contents of the invention [0004] The object of the present invention is to provide an intravascular biopsy device to solve the above-mentioned technical problems in the prior art. [0005] The intravascular biopsy device provided by the present invention includes a biopsy forceps, a rotating sleeve, an angle adjustment reset mechanism, an outer sheath, a fixed balloon, and an injection catheter; [0006] The biopsy forceps comprises a forceps head, a long arm and an operating handl...
