Abstract

The invention discloses a neurosurgical posterior cranial distraction drainage device, which comprises a support mechanism, a distraction mechanism and a drainage mechanism. The support mechanism comprises a U-shaped frame, a hydraulic cylinder, a bottom plate, an electric push rod, a sleeve, a rotating shaft and a driving motor; the distraction mechanism comprises an adjusting part and a pair ofdistraction parts, and the adjusting part comprises a U-shaped seat, an L-shaped fixed rod, a stepping motor, a screw rod and a sliding block; and each distraction part comprises a hinge chain, a first sliding cylinder, a first spring rod, a second sliding cylinder, a second spring rod, a sliding rod and a reset spring; and the drainage mechanism comprises a telescopic rod, a drainage tube, an infusion pump, a catch box, a spring lock bolt and a fixing ring. By adopting the support mechanism, the distraction mechanism and the drainage mechanism, the surgical incision of a patient can be effectively opened and fixedly supported, the situation that the device tears the skin of the patient in the process of opening the surgical incision of the patient can be effectively avoided, and hydrops in the surgical incision of the patient can be effectively drained.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a neurosurgery posterior cranial distraction drainage device. 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. Injuries, inflammations, tumors, deformities, and certain genetic metabolic disorders or dysfunctional diseases of the skull, scalp, cerebrovascular meninges and other structures, so in neurosurgery, it is often necessary to perform intracranial surgery on the posterior cranium of the patient to treat the corresponding diseases.

[0003] In neurosurgery posterior cranial surgery, it is often necessary to use support devices and drainage devices in conjunction with surgery, but most of the existing devices have single functions ...
