Abstract

The scheme discloses a scalpel for neurosurgery department in the technical field of medical devices. The top of a holding rod is located below a pushing rod and a gap is reserved between the pushingrod and the holding rod; a knife handle is provided with an air bag, an upper cavity and a lower cavity are arranged in the knife handle, a spring and a piston rod are arranged in the upper cavity, one end of the spring is fixedly connected in the upper cavity, the other end of the spring is connected with the piston rod, the piston rod penetrates the knife handle and is fixedly connected with thepushing rod and is slidely connected with the knife handle, and the air bag is communicated with the upper cavity and is located between the spring and the piston rod. The piston rod, a lotion pipe and the knife handle are all located on a same vertical surface, the lower cavity is communicated with a through hole arranged on a pipette, the knife handle is provided with a liquid outlet, the liquid outlet is communicated with the lower cavity, and the knife handle is also provided with a sealing cover for sealing the liquid outlet. When performing neurosurgery for patients with the scalpel forneurosurgery department, not only the hematocele and oozed blood generated during the operation can be absorbed, but also the reflux of the hematocele and the oozed blood can be avoided.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a scalpel for neurosurgery. Background technique [0002] Neurosurgery is a branch of surgery, which uses unique neurosurgery research methods to study the human nervous system, such as the brain, spinal cord and peripheral nervous system, as well as related diseases, based on surgery as the main treatment method. Subsidiary organs, such as skull, scalp and cerebrovascular meninges and other structural injuries, inflammation, tumors, deformities and certain genetic metabolic disorders or dysfunctional diseases, such as: the etiology and pathogenesis of epilepsy, Parkinson's disease, neuralgia and other diseases , and explore new diagnostic, therapeutic and preventive technologies as a high-level, precise and cutting-edge discipline. [0003] During neurosurgery, drainage tubes are often placed in the epidural, subdural, tumor residual cavity, wound cavity...
