Description

Technical Field

[0001] The invention relates to the field of medical device optical products, in particular to a disposable soft imaging catheter for removing intracranial hematoma. Background Art

[0002] At present, intracranial hematoma is a very common disease in the field of cerebrovascular surgery. The causes of hematoma include brain trauma and cerebrovascular diseases such as aneurysms, vascular malformations, moyamoya disease, and cerebral hemorrhage caused by hypertension. The amount of bleeding is small, and the damage to brain tissue is relatively small, so surgery is generally not required. For cases with a bleeding volume greater than 30-40 ml, pure drug treatment cannot guarantee the later recovery effect. The hematoma will compress and damage the brain tissue, causing irreversible lesions, and surgical intervention is required to remove the hematoma. The current clinical surgical method is to outline the location of the bone flap window outside the brain with the support of imaging data such as CT / MRI, and remove the brain hematoma. Rigid neuroendoscopy has been widely used in clinical diagnosis and treatment. Especially in neurosurgery transsphenoidal approach surgery and ventricular drainage, hematoma caused by craniocerebral trauma, abscess treatment, and congenital or acquired hydrocephalus in children, neuroendoscopy is used. The disadvantage of the rigid optical tube endoscope is that it cannot be bent. Summary of the invention

[0013] (III) Beneficial effects

[0014] The present invention provides a disposable soft imaging catheter for removing intracranial hematoma, which has the following beneficial effects:

[0015] 1. A snake-bone steel wire is embedded in the silicone sleeve to increase the hardness of the silicone tube. The snake-bone steel wire can be pulled as the angle of the handle is adjusted to change the angle of the silicone tube, so as to better adjust the angle and fit the structure of the anatomical tissue.

[0016] 2. In addition to the snake-bone steel wire, the silicone tube has a built-in CMOS chip for imaging in liquid environments, and 3 1-1.2mm forceps channels. It is used for flushing, suction, electrocoagulation and other surgical operations. The entire operation process can be observed under the guidance of the imaging of the CMOS chip, which more effectively protects the patient's normal tissue from being disturbed.
