Abstract
The utility model discloses a novel tapping device for spinal cord, which comprises an iron stand, a tapping weight, a weight for balance weight, an electromagnet, an introducer, a twin adhesive tape and a plurality of lightweight tie lines; wherein, the electromagnet is arranged at an upper cross rod; the spinal cord tapping introducer is arranged at a lower cross rod; two tie lines are arranged at the tying part of the spinal cord tapping weight: one is used for connecting with the weight for balance weight and the other is used for connecting with the iron sheet attracted on the electromagnet; the twin adhesive tape is adhered to the contact surfaces of the introducer and the weight. The utility model adopts the mode of free falling body time difference of double weights, that is, the tapping weight and the weight for balance weight fall at the same time; when the tapping weight falls again after tapping the spinal cord and springing, the falling journey of the weight for balance weight is longer; when fallen to certain height, the tie line between the tapping weight is tensioned, thereby causing bigger speed and weight than the tapping weight; the tapping weight is pulled upwards, and meanwhile the tapping weight pulls the introducer through the twin adhesive tape, thereby stopping secondary tapping spinal cord and improving the accuracy of making injured model for the spinal cord.
Description
Technical field
This utility model relates to spinal cord injury research instrument field.
Background technology
Spinal cord injury model is set up the freely falling body whereabouts of adopting and is impacted mode at present, it is more convenient that this kind mode is made spinal cord injury model, impacting dosage can control, the model of making is through the relatively more approaching actual traumatic condition of a large amount of experiment confirms, but this kind mode exists shortcoming, promptly impact the spinal cord problem repeatedly, after upspringing, falling objects falls to impacting spinal cord once more, the accuracy of influence experiment, occur the photo-electric control mode in view of the above at present and prevent to impact once more spinal cord, but its complexity as a result, the cost height, volume is big, and range of application is little.
The utility model content
It is a kind of simple in structure, easy to operate that the technical problems to be solved in the utility model is to provide, and cost is low, and can prevent to impact once more spinal cord, effectively improves the accuracy that spinal cord injury model is made.
In order to solve the problems of the technologies described above, this utility model adopts following technical scheme: a kind of novel spinal cord beating unit, comprise iron stand, impact counterweight, conductor, electric magnet, counterweight counterweight and electromagnetism iron phase attract, it is characterized in that: also comprise a counterweight counterweight that attracts with the electromagnetism iron phase, impact counterweight and be connected by anchor line (string) with the counterweight counterweight.Described conductor comprises the guiding sleeve and can guide the striking rod of motion in the sleeve that striking rod is stained with double faced adhesive tape with the contact surface that impacts counterweight.
Design concept of the present utility model is to adopt two counterweight freely falling body time difference modes when impacting spinal cord, promptly impact counterweight and the counterweight counterweight falls simultaneously, when impacting when upspringing after counterweight impacts spinal cord to fall once more, counterweight counterweight whereabouts stroke is longer, during the whereabouts certain altitude in the anchor line (string) tension that impacts between the counterweight, it is big to cause that speed and quality impact counterweight, to impact the counterweight pull-up, impact simultaneously counterweight by double faced adhesive tape with the conductor pull-up, so stop secondary to impact spinal cord, improved the accuracy that spinal cord injury model is made.
Based on above design, this utility model adopts following technical scheme: a kind of novel spinal cord beating unit comprises iron stand, impacts counterweight, attracts ferrum, counterweight counterweight, electric magnet, conductor, double faced adhesive tape and lightweight anchor line (string).A kind of preferred version as technique scheme: electric magnet is placed cross tube, spinal cord impacts conductor and places sheer pole, there are two root system lines at the anchor line (string) place that spinal cord impacts counterweight, one is used to connect the counterweight counterweight, one is used to be connected in attraction ferrum, is stained with double faced adhesive tape on conductor and the counterweight contact surface.Electric magnet energising generation magnetic attraction is connected in iron plate and the counterweight counterweight that impacts counterweight before impacting, conductor aiming spinal cord, outage impacts counterweight and the counterweight counterweight descends simultaneously, impacting counterweight upsprings, when not impacting spinal cord once more, the counterweight counterweight descends and puts in place, and the tension anchor line (string) impacts the counterweight pull-up with spinal cord, thereby realizes once impacting fully spinal cord.
Description of drawings
Fig. 1 is the overall structure figure of a kind of novel spinal cord beating unit of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
A kind of novel spinal cord beating unit shown in Figure 1 comprises iron stand 1, striking rod 2, guiding sleeve 3, double faced adhesive tape 4, impacts counterweight 5, counterweight counterweight 6, attracts ferrum 7, electric magnet 8, and lightweight anchor line (string) 9, power line 10.
Mounting means of the present utility model is as follows: electric magnet 8 is placed iron stand 1 cross tube, guiding is overlapped 3 in sheer pole, striking rod 2 moves up and down in guiding sleeve 3, there are two root system lines 9 at the anchor line (string) place that impacts counterweight 5, one is used to be connected in counterweight counterweight 6, one is used to be connected in and attracts ferrum 7, is stained with double faced adhesive tape 4 on striking rod 2 and the contact surface that impacts counterweight 5, and electric magnet 8 is connected in power line 10.
Its operation principle: electric magnet energising generation magnetic attraction is connected in iron plate and the counterweight counterweight that impacts counterweight before impacting, striking rod aiming spinal cord in the guiding sleeve, outage impacts counterweight and the counterweight counterweight descends simultaneously, impacting counterweight upsprings, when not impacting spinal cord once more, the counterweight counterweight descends and puts in place, and the tension anchor line (string) will impact the counterweight pull-up, thereby realizes once impacting fully spinal cord.
Claims (2)
1. novel spinal cord beating unit, comprise iron stand, impact counterweight, conductor, electric magnet, counterweight counterweight and electromagnetism iron phase attract, and it is characterized in that: also comprise a counterweight counterweight that attracts with the electromagnetism iron phase, impact counterweight and be connected by anchor line (string) with the counterweight counterweight.
2. a kind of novel spinal cord beating unit according to claim 1 is characterized in that: described conductor comprises the guiding sleeve and can guide the striking rod of motion in the sleeve that striking rod is stained with double faced adhesive tape with the contact surface that impacts counterweight.
