Head fixing device for neurosurgery department

Abstract

The invention relates to the technical field of medical devices, and discloses a head fixing device for the neurosurgery department. The head fixing device comprises a bottom plate, a fixed barrel ismounted in the middle of the upper end of the bottom plate, a lead screw is mounted in the fixed barrel, a lifting disc connected to the middle of the lead screw through a threaded structure and lifting rods mounted at the two ends of the lifting disc; the lifting rods penetrate through limiting grooves arranged at the middles of the two ends of the fixed barrel and are connected with traction ropes; a fixed plate is arranged on the upper end of the fixed barrel, traction frames are installed at the two sides of the lower end of the fixed plate, a rotating shaft is arranged in the middle of the lower end of each traction frame, and a traction wheel is installed at the middle of each rotating shaft, guide grooves are formed in the upper end of the fixed plate, guide springs are installed atthe bottom ends in the guide grooves, guide columns are installed at the upper ends of the guide springs, the upper ends of the guide columns penetrate through a top plate arranged at the upper end of the fixed plate and are connected with a headrest, the two ends of the top plate are hinged with clamping frames through joint shafts, and side pillows are arranged on the inner sides of the clamping frames. According to the head fixing device, the effective clamping and fixing effect of the clamping frames on the head is achieved, and adaptive adjustment can be conducted according to the headsof different sizes.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a head fixation device 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, 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 to explore new diagnostic, therapeutic and preventive technologies as a high-level discipline. Neurosurgery needs to use a head immobilization device to fix the patient's head during surgery, which is convenient for medical staff to perform surg...

AI Technical Summary

Problems solved by technology

[0003] There is no corresponding head fixation device on the existing operating bed, and it is inconvenient to perform adaptive fixation on the patient's head during the operation, which is poor in flexibility and inconvenient for medical staff to operate on the patient's head

Chinese patent (notification number: CN210494529U) discloses a head fixation device for neurosurgery, including a fixing base, a push rod motor is fixedly connected to the top of the fixing base, a placement frame is fixedly connected to the output shaft of the push rod motor, and the placement frame It is a U-shaped structure, and both sides of the placement frame are horizontally slidable and installed with push rods. The tops of the two lower pressing rods are all fixedly connected with the same support plate, and the two lower pressing rods are matched with the two push rods respectively. Although the device can fix the head to a certain extent, the device is based on the patient The gravity of the head is used as the power source. Once the head moves up during the operation, the fixation will fail, which will seriously affect the effect of the operation. Therefore, further improvement is needed.
