A kind of aneurysm clip holding forceps

Abstract

The invention discloses an aneurysm clip holding forceps, which includes a clip holding forceps main body. In the present invention, serpentine arms are arranged on the clip holding forceps main body. The serpentine arms are spliced ​​together by a bottom joint, several middle joints and a top joint. Together, the top of the bottom joint and the top of the middle joint are fixed with ball knots, and the bottom of the middle joint and top joint are fixed with ball knot placement slots, which can adjust the serpentine arm to any angle, which is flexible and convenient. The double lug nut can adjust the angle of the pliers head, which has changed the defect that the previous clamps were not flexible enough to hold the pliers head and could not rotate. The bottom joint, the middle joint and the top joint are all internal hollow tubes, which reduces the manufacturing cost while reducing the overall weight. By arranging an operating mechanism under the bottom joint, the manipulation of the forceps head at the distal end can be realized, which can effectively avoid the limitation of the field of vision during the operation, and is conducive to popularization and promotion.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an aneurysm clip holding forceps. Background technique [0002] Intracranial aneurysm refers to a tumor-like protrusion of the arterial wall caused by a localized abnormal expansion of the lumen of a cerebral artery. Intracranial aneurysm is mostly caused by cystic bulge due to local congenital defects of the cerebral artery wall and increased intracavitary pressure. It is the first cause of subarachnoid hemorrhage. The cause of aneurysm is not very clear. The etiology of neoplasia can be summarized as follows: ①Congenital factors; ②Atherosclerosis; ③Infection; ④Trauma. In addition, there are some rare reasons such as tumors can also cause aneurysms, abnormal skull base vascular network disease, cerebral arteriovenous malformation, intracranial vascular abnormalities and cerebral artery occlusion can also be associated with aneurysms. [0003] At present, there are ...

Problems solved by technology

The gun-shaped finger-ring placement forceps CASPAR clip holding forceps can be rotated freely within 360° to ensure smooth placement of cerebral aneurysms at any angle. Due to the limitation, it is easy to cause the holder to be unstable

The operation requires precise positioning, so the operation is more difficult, and the surgical field of view is limited. The tweezers-type placement forceps, such as the YASARCIL clip holding forceps, are five-finger holders, which solve the above-mentioned problems that the CASPAR clip holding forceps has two fingers. However, because the jaws are scissor-shaped, the jaws are limited by their structure and cannot be rotated. Therefore, it is not convenient to place cerebral aneurysms smoothly in different diseased parts. The first generation of aneurysm clips often block the surgical line of sight. Improvement The latter is a direction-adjustable aneurysm clamp holding forceps combined with the principle of a serpentine pull hook. The middle section of the rod can be made into an aneurysm holding forceps that can be freely transformed into any angle, which is convenient for handling aneurysms of different angles during surgery.

The second-generation head is made smaller, but it is still not flexible enough, and the angle of the head cannot be rotated, so it is necessary to design a new type of aneurysm clip holding forceps to solve these problems
