Description

Restraint device for neurosurgery Technical Field The invention belongs to the technical field of medical equipment, and particularly relates to a restraint device for neurosurgery. Background Neurosurgery patients, especially patients with postoperative, conscious disturbance or agitation period, often need to effectively restrict the head and limbs to prevent the patients from self-injury (such as pulling out drainage tube and infusion tube) or injuring medical staff, and ensure the smooth treatment. Currently, the most commonly used restraint devices in clinic mainly comprise simple strapping, stent-type and recently appeared inflatable restraint devices. There are a number of restriction devices designed for neurosurgical patients in the prior art. Patent document CN117323157a discloses a restraint device for neurosurgery, which comprises a back plate and two groups of restraint clamping assemblies, wherein the clamping members are synchronously moved towards each other by a motor driving a threaded rod, so that the shoulder and the waist of a patient can be restrained and fixed. The device realizes manual fine adjustment through the independent sliding of the clamping piece on the sliding frame, so that the clamping piece is gently attached to the limb of a patient. Patent document with publication number CN118078512A discloses a patient's limbs restraint device for neurosurgery, including synchronous rolling constraint subassembly and lift constraint subassembly, drive the wind-up roll through worm gear mechanism and wind upper body constraint area and wind, utilize the self-locking of worm gear to avoid the patient to struggle and lead to constraint area to become flexible. Patent document CN215425405U discloses a restraint device for neurosurgery nursing, which innovatively sets a spacer for containing non-newton fluid on the side of the restraint soft board contacting with the limb, and automatically limits the movement of the limb when the patient is in sudden agitation by utilizing the characteristic that the non-newton fluid presents high resistance when rapidly impacting. However, despite the advances made in the prior art described above, the following drawbacks remain: Firstly, the control of the constraint force is rough, and accurate dynamic adjustment is difficult to realize. The prior device such as CN117323157B adopts a manual fine adjustment mode, and can realize preliminary fitting, but can not adjust the constraint force in real time according to the state of a patient. Clinical studies have shown that the use of head fixation devices requires precise control of nail torque and bone conditions, which may lead to complications such as skull fractures, epidural hematomas, etc. If the fixation is too loose, when the patient is severely agitation, the limbs are easy to break loose, not only effective constraint cannot be realized, but also accidental tube drawing or bed falling can be caused by the severe struggling of the patient, if the fixation is too tight, local tissues can be pressed for a long time, and pressure injury, blood circulation disorder and even nerve injury are easy to be caused. Secondly, when the body position is required to be changed (such as a regular turn-over), the operation process is extremely complicated and the body position self-adaption cannot be realized. The restraint assembly of the existing device is fixed on the bed body or the back plate, when a patient needs to turn over, medical staff must unlock a plurality of fixing structures one by one, then the patient is manually assisted to turn over, and finally the restraint belt is readjusted and fixed. This process not only takes a lot of manpower and time, but also, in the gap of the refastening, the patient is in an unconstrained state, presenting a safety risk. More importantly, the body shape of the patient after turning over changes, the original fixed point is shifted, and the new body position is difficult to adapt to by simple rebinding, so that the fixing effect is poor or the patient is uncomfortable. Solutions for automatically adjusting the constraint state along with the body position change of a patient are not known in the prior art. Finally, the prior restraining device has limited restraining range and lacks systematic protection on important parts such as the head, the neck and the like. Currently, the common restraining devices are mostly aimed at the trunk and the limbs, and do not provide special restraint and support for the head and the neck. However, for neurosurgical patients, head and neck stabilization is critical. The patient can swing the head severely due to agitation after operation, which not only can influence the intracranial pressure stabilization, but also can lead to traction on the operation incision; if the head of a patient with unstable cervical vertebra lacks effective support and guide in the turning process, the cervical vertebra is extremely easy to twist or ove
