Abstract
The utility model discloses a longitudinal regulating skull traction bow, which belongs to medical equipment. The utility model comprises two tong bodies which are mutually hinged into an opening tong shape, and an opening adjusting mechanism, wherein working ends of the two tong bodies are respectively provided with fixed needles; the opening adjusting mechanism is composed of a link rod, an adjusting bolt, an adjusting nut and a nut connecting sleeve; the adjusting nut, the exicrcle of which is provided with a slide way is clamped and connected to the inside of the nut connecting sleeve in a sliding way; the nut connecting sleeve is hinged with the upper end of the link rod, the lower end of which is hinged with the hand-held end of the tong bodies; the adjusting bolt, the lower end of which is hinged on the hinged point of the two tong bodies is connected with adjusting nuts through threads. The skull traction bow of the utility model has the characteristics of convenient use, not easy unhooking, etc.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of vertical adjusting skull traction bow that is used for skull traction.
Background technology
Skull traction of the prior art bow is made of two calipers that are hinged to the opening tong-like, is provided with opening at the handheld terminal of caliper and regulates bolt, articulates the pin joint place that sheet is arranged on two calipers.Because of structural deficiency; the extent of opening of two calipers only is subjected to the restriction that opening is regulated bolt; loosening in the distraction procedure through regular meeting; prevent the appearance of locking hook accident; medical personnel just must regulate the adjusting nut of caliper end at set intervals, have increased medical personnel's workload and patient's misery so to a great extent.
Summary of the invention
Technical assignment of the present utility model is to provide a kind of vertical adjusting skull traction bow at above-mentioned deficiency of the prior art, and this skull traction bow has characteristics such as rational in infrastructure, easy to use, difficult unhook.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of vertical adjusting skull traction bow, its structure comprises two calipers and the opening governor motion that is hinged into the opening tong-like, two caliper working ends are respectively arranged with locking pin, the opening governor motion is by trace, regulate bolt, adjusting nut and nut adapter sleeve constitute, the adjusting nut slip that cylindrical has chute is connected in the nut adapter sleeve, the upper end of nut adapter sleeve and trace is hinged, the lower end of trace and caliper handheld terminal are hinged, and the adjusting bolt that the lower end is articulated in the pin joint of two calipers joins by screw thread and adjusting nut.
Be provided with in the upper end of regulating bolt and articulate ring.
Vertical adjusting skull traction bow of the present utility model is compared with prior art, trace and caliper in the opening governor motion are hinged to diamond structure, regulating bolt vertically becomes a diagonal of this diamond structure, change this cornerwise length by adjusting nut, it is its subtended angle of scalable, because be to be arranged on the top of regulating bolt, just can not occur loosening phenomenon during traction again, can avoid the generation of unhook accident fully articulating ring.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of vertical adjusting skull traction bow.
The specific embodiment
Explain below with reference to Figure of description a kind of vertical adjusting skull traction bow of the present utility model being done.
As shown in drawings, a kind of vertical adjusting skull traction bow of the present utility model, its structure comprises caliper 1 and drives governor motion, wherein, two calipers 1 that the working end is provided with locking pin 2 are hinged into the opening tong-like, the opening governor motion that is arranged on caliper 1 handheld terminal is by trace 3, regulate bolt 4, adjusting nut 5 and nut adapter sleeve 6 constitute, adjusting nut 5 slips that cylindrical has chute are connected in the nut adapter sleeve 6, nut adapter sleeve 6 is hinged with the upper end of trace 3, the lower end of trace 3 and caliper 1 handheld terminal are hinged, regulating bolt 4 joins by screw thread and adjusting nut 5, the bottom of regulating bolt 4 is a laminated structure, join with the pin joint 7 of two calipers 1, also be provided with on the top of regulating bolt 4 and articulate ring 8.
It is very simple and convenient that a kind of vertical adjusting skull traction of the present utility model bends its processing and fabricating, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of description, be the known technology of those skilled in the art.
