Description
Technical field
This utility model relates to a kind of medical auxiliary apparatus, especially a kind of neurosurgery head fixing device.
Background technology
When neurosurgery, doctor needs first patient's head to be fixed to carry out operation technique, if head is fixing not firm, likely has influence on normally carrying out of operation, even can cause great danger to patient.The patent of publication number CN203263726U discloses a kind of neurosurgery head fixing device, the moving threaded rod of hand-screw for this device, make clamping plate clamp that patient head is fixed, this device in use mainly has the following disadvantages: 1, when turn threaded rod, because the power that both hands are used is inconsistent, can cause head fixing not just, impact operation; 2, when clamping head, clamping plate are unclear to head applied pressure, obtain inquiring about disease people and hold tightly or not, but patient now anaesthetizes mostly, cannot learn the problem of pressure size, can only determine with doctor's experience, if pressure is excessive, can affect the blood circulation of head; When pressure is too small, patient head is fixing not firm, the accuracy of impact operation; 3, in operation process, because patient head is opened cranium, cause head internal pressure to reduce, head diameter is reduced slightly, original fixing state is aobvious too loose, and head is fixing not tight, must again debug clamping plate, and operation is trouble very.
Summary of the invention
Technical assignment of the present utility model is to provide a kind of neurosurgery head fixing device for above the deficiencies in the prior art.
This utility model solves the technical scheme that its technical problem adopts: a kind of neurosurgery head fixing device, comprise arc head rest, in the both sides of described arc head rest, be symmetrically connected with respectively left cylinder and right cylinder, piston in described left cylinder is connected with left clamping plate by connecting rod, piston in described right cylinder is connected with right clamping plate by connecting rod, the air inlet of described left cylinder communicates with inflator by left airway, on described left airway, be provided with left electromagnetic valve, the air inlet of described right cylinder communicates with inflator by right airway, described inflator is connected with controller, on described right airway, be provided with right electromagnetic valve, on described left clamping plate, be provided with left pressure transducer, on described right clamping plate, be provided with right pressure transducer, described left electromagnetic valve, right electromagnetic valve, left pressure transducer and right pressure transducer are electrically connected to controller respectively.
On described left cylinder and right cylinder, be respectively equipped with relief valve, its objective is that pressure transducer and controller break down, while causing uncontrollable pressure, relief valve plays pressure release effect, to protect patient head to be subject to excess pressure.
The advantage that this utility model produces is: 1, inflator is given the cylinder air feed of both sides simultaneously, and the power while making both sides clamping plate clamp patient head is consistent, and therefore, head is accurately fixing, is conducive to hands art; 2, being provided with sensor allows the fixedly operation of patient head become automatization, do not need manually to debug, make the pressure of both sides clamping plate be in all the time the pressure state of setting, neither can affect the blood circulation of patient head, can not make head fixing not firm because of pine excessively yet, the accuracy of impact operation, has reached automatization's control, allows doctor vacate more energy and performs an operation; 3, the pressure of regulating and controlling two side guides separately, controls patient head more accurate, is more conducive to carrying out smoothly of operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with Figure of description, this utility model is described below.
As shown in Figure 1, a kind of neurosurgery head fixing device, comprise arc head rest 1, in the both sides of described arc head rest 1, be symmetrically connected with respectively left cylinder 5 and right cylinder 13, piston 7 in described left cylinder 5 is connected with left clamping plate 9 by connecting rod 8, piston 7 in described right cylinder 13 is connected with right clamping plate 12 by connecting rod 8, the air inlet of described left cylinder 5 communicates with inflator 4 by left airway 15, on described left airway 15, be provided with left electromagnetic valve 3, the air inlet of described right cylinder 13 communicates with inflator 4 by right airway 16, described inflator 4 is connected with controller 2, on described right airway 16, be provided with right electromagnetic valve 14, on described left clamping plate 9, be provided with left pressure transducer 10, on described right clamping plate 12, be provided with right pressure transducer 11, described left electromagnetic valve 3, right electromagnetic valve 14, left pressure transducer 10 and right pressure transducer 11 are electrically connected to controller 2 respectively.
On described left cylinder 5 and right cylinder 13, be respectively equipped with relief valve 6, its objective is that pressure transducer and controller break down, while causing uncontrollable pressure, relief valve plays pressure release effect, to protect patient head to be subject to excess pressure.
During use, patient's head is placed in head rest 1, ajusted patient head position, open inflator 4 and promote piston 7 to left cylinder 5 and 13 inflations of right cylinder, make left pressing plate 9 and right pressing plate 12 clamp patient's head, when pressure reaches after the state value of setting, left pressure transducer 10 and right pressure transducer 11 send signal to controller 2, controller 2 after comparings, close left electromagnetic valve 3 and right electromagnetic valve 14, in operation process, when the pressure decreased of 9 pairs of heads of left clamping plate, left pressure transducer 10 can send signal at once to controller 2, controller 2 can be opened left electromagnetic valve 3 to cylinder 5 air feed, the pressure that makes 9 pairs of patient head of left clamping plate is the pressure state in setting all the time, equally, when 12 pairs of head pressure decreaseds of right clamping plate, right pressure transducer 11 can send signal at once to controller 2, controller 2 can be opened right electromagnetic valve 14 to cylinder 13 air feed, the pressure that makes 12 pairs of patient head of right clamping plate is the pressure state in setting all the time.
