Neurosurgical posterior cranial distraction drainage device

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 ...

Problems solved by technology

[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 and cannot combine the two, nor can they meet the different use requirements in posterior cranial surgery

[0004] In the patent application publication number CN 107823732 A, a neurosurgical posterior cranial distraction drainage device is disclosed, which includes a base, the base is a "Zhu" type plate, and the upper surfaces of the two ends of the base are relatively fixed with fixing plates , the shaft hole of the fixing plate is provided with a rotating shaft, the structure is simple, and the whole is fixed through the base, the skull at the operation position is stretched by the relative movement of the two pulling plates, and the intracranial bone is drained through the drainage tube and the negative pressure pump. The bleeding is drained into the negative pressure cylinder. The high position of the outlet of the drainage tube can effectively prevent the liquid in the negative pressure cylinder from flowing down. The deflection angle of the arm plate can be adjusted, and the position of the sliding seat on the arm plate can be adjusted. The height of the board and the drainage tube can also be adjusted accordingly, so that the drainage tube can safely enter the intracranial and reach the designated depth, thereby improving the success rate of the operation, reducing the risk of complications, and reducing the work difficulty of the medical staff; but its There are the following disadvantages: in this application, the arm plate has a circular arc structure, and the skull at the operation position is stretched by the movement of the arm plate, and the arm plate moves along the arm plate as a whole, so in the process of stretching the posterior skull , it is very easy to block the position of the incision, and it is easy to reduce the convenience for doctors to operate near the incision, and the puller does not have a buffer mechanism, which is very easy to cause the phenomenon of tearing the incision in the process of opening the posterior skull. At the same time, the drainage device is fixed On the stretching mechanism, the angle cannot be adjusted independently, and it cannot meet the fluid drainage under the complex structure inside the incision during the operation, and the overall applicability of the device is not good.
