It is using the advantageous effect after such scheme：Arc location-plate is with in the angle adjustment lifted according to patients headThe position of arc pallet, so that upper arc location-plate is clamped on forehead or the head of patient, makes arc lower supporting plate hold up patientAt chin, and by the upper-lower position of the upper arc location-plate of upper cylinder adjustment, adjusted by lower oil cylinder above and below arc lower supporting platePosition, can thus realize the auxiliary positioning of patients head, and suitable different new line angles are used, highly versatile.
Brief description of the drawings
The embodiment to the present invention is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is the structural representation of the present invention；
Fig. 2 is Fig. 1 right view.
Embodiment
As Figure 1-Figure 2, the neurosurgery head treatment fixing device includes frame 1, and the top of frame 1 is provided with upper cunningSlidably connect upper cylinder 21 on road 2, sliding way 2, the middle part of sliding way 2 is provided with chute, upper cylinder 21 is slidably connected above-mentioned cunningIn groove, the sidepiece of sliding way 2 is provided with and upper cylinder 21 coordinates holds out against spiral shell in strip hole provided with the strip hole with chute insertionBolt, the positioning of upper cylinder 21 can be realized by puller bolt by adjusting behind the position of upper cylinder 21.The expansion link of upper cylinder 21 is wornCross sliding way 2 and under stretch, the lower extending end of the expansion link of upper cylinder 21 is connected with the first upper connecting rod 3, the lower end of the first upper connecting rod 3The bottom that portion is rotatably connected to the first upper connecting rod 3 in the second upper connecting rod 4, the present embodiment is provided with connection on circular groove, secondThe upper end of bar 4 is provided with the ball that turns being rotatably connected in circular groove, the rotation annexation between the present embodiment transfer ball and circular grooveFor prior art, it will not be repeated here, this annexation can make to connect on the multi-angle rotation of the second upper connecting rod 4, firstBar 3 is provided with turns the tight lifting pin 11 that ball coordinates with above-mentioned, adjusts after the rotational angle of the second upper connecting rod 4 by tight lifting pin 11Realize positioning.The bottom of second upper connecting rod 4 is connected with arc location-plate 5, the present embodiment upper arc location-plate 5Curved arc angle and human body forehead portion or head be adapted.
As Figure 1-Figure 2, the bottom of frame 1 is provided with the glide path 6 being be arranged in parallel with sliding way 2, glide path 6 and slidedLower oil cylinder 7 is connected with, the middle part of glide path 6 is provided with chute, and lower oil cylinder 7 is slidably connected in above-mentioned chute, the sidepiece of glide path 6Provided with the strip hole with chute insertion, the puller bolt coordinated with lower oil cylinder 7 is provided with strip hole, the position of lower oil cylinder 7 is adjustedThe positioning of lower oil cylinder 7 can be realized by puller bolt by postponing.The lower expansion link of oil cylinder 7 through glide path 6 and on stretch, lower oil cylinder 7The up extension end of expansion link is connected with the first lower connecting rod 8, and the upper end of the first lower connecting rod 8 is rotatably connected to the second lower connecting rod9, the upper end of the first lower connecting rod 8 is provided with circular groove, and the bottom of the second lower connecting rod 9, which is provided with, is rotatably connected on turning in circular grooveBall, the rotation annexation between the present embodiment transfer ball and circular groove is prior art, be will not be repeated here, this annexationThe multi-angle rotation of the second lower connecting rod 9 can be made, the first lower connecting rod 8 is provided with and the above-mentioned tight lifting pin 11 for turning ball cooperation, tuneRealized and positioned by tight lifting pin 11 after the rotational angle of whole second lower connecting rod 9.The upper end of second lower connecting rod 9 is consolidatedIt is connected to arc lower and determines arc lower in supporting plate 10, the present embodiment and determines the curved arc angle of supporting plate 10 with being adapted at human body chin
Upper arc location-plate 5 is determined supporting plate with arc lower and is correspondingly arranged about 10 in the present embodiment, the phase of upper arc location-plate 5Inner surface is provided with spongy layer 20, and the opposite inner face that arc lower determines supporting plate 10 is provided with spongy layer 20, spongy layer 20 and human body skinSkin is directly contacted, and sweat stain can also be absorbed while improving comfort level.
As shown in Fig. 2 the length of the left end of sliding way 2 is more than the length of the left end of glide path 6 in the present embodiment, suffer from when usingHead is placed between the up and down slideway of left part by person, and arc location-plate 5 is with in the angle adjustment lifted according to patients headThe position of arc pallet 10, so that upper arc location-plate 5 is clamped on forehead or the head of patient, holds up arc lower supporting plate 10At patient's chin, and by the upper-lower position of the upper arc location-plate 5 of the adjustment of upper cylinder 21, pass through lower oil cylinder 7 and adjust arc lower supportThe upper-lower position of plate 10, can thus realize the auxiliary positioning of patients head.Patients head lift angle it is big when, upper arc determinePosition the distance between plate 5 and arc lower supporting plate 10 are just big, on the contrary, patients head lifts angle hour, upper arc location-plate 5 is withThe distance between arc pallet 10 is just small.
