Arachnoid scissors

Abstract

The invention discloses arachnoid scissors, and belongs to the field of medical surgical instruments. The pair of arachnoid scissors comprises an arachnoid scissors body, the arachnoid scissors body is divided into a pair of scissors body and scissors head which are connected with each other, and comprises an auxiliary push handle, a push plate, a storage box, a pair of film suction pipes, an abutting block, a puncture needle and a pair of extraction grooves. The storage box is arranged on the outer surface of the scissor body on one side, and a storage cavity with an opening facing the scissor head is formed in the storage box. The abutting block is contained in the containing cavity and faces the opening of the containing cavity. The pair of film suction pipes is symmetrically distributed at the bottom of the abutting block. According to the novel arachnoid scissors, the puncture needle can be placed on one side face of the scissors body, so that before the arachnoid is cut open, the first notch of the arachnoid can be conveniently opened through the puncture needle, and therefore the situation that when the scissors head stretches into the arachnoid to scratch brain tissue or damage important nerve blood vessels under the arachnoid due to overexertion when the scissors head is used for cutting open the arachnoid is avoided.

Description

technical field [0001] The invention relates to the field of medical operation instruments, and more specifically, relates to an arachnoid scissors. Background technique [0002] With the development of microneurosurgery technology, in various neurosurgery operations that require incision of the dura mater, such as minimally invasive skull base surgery and posterior fossa-pontine cerebellar angle surgery, the bone window that meets the surgical operation needs is getting smaller and smaller Its operation operation space is narrow, and causes operation inconvenience. [0003] However, because the tip of the scissor arm of the existing surgical scissors is relatively sharp and sharp, and the fluctuation of intracranial cerebrospinal fluid will cause the position of the arachnoid to be unstable, it is very easy to scratch the brain tissue or damage important nerves under the arachnoid when opening the arachnoid Blood vessels cause contusion on the brain surface, damage to impo...

Problems solved by technology

[0002] With the development of microneurosurgery technology, in various neurosurgery operations that require incision of the dura mater, such as minimally invasive skull base surgery and posterior fossa-pontine cerebellar angle surgery, the bone window that meets the surgical operation needs is getting smaller and smaller Its surgical operation space is narrow, resulting in inconvenient operation

[0003] However, because the tip of the scissor arm of the existing surgical scissors is relatively sharp and sharp, and the fluctuation of intracranial cerebrospinal fluid will cause the position of the arachnoid to be unstable, it is very easy to scratch the brain tissue or damage important nerves under the arachnoid when opening the arachnoid Blood vessels cause contusion on the brain surface, damage to important nerves and blood vessels, and blurred surgical field of view. On the one hand, it takes time to stop bleeding and flush the surgical field, which is time-consuming and laborious; on the other hand, it also causes safety hazards and increases postoperative complications such as intracranial hemorrhage. , and affect future recovery

At the same time, it is more difficult to use surgical scissors to open the first gap in order to cut the arachnoid, and it is easy to accidentally scratch the brain tissue or neurovascular
