Description
Technical field
This utility model belongs to medical instruments field, specifically, is a kind of adjustable skull traction frame for traumatism treatments such as fracture of cervical vertebra, dislocations.
Background technology
It is one of major way for the treatment of cervical spondylosis and cervical spinal trauma that anterior cervical decompression merges.When anterior cervical operation, keep the definite fixing and suitable curvature of cervical vertebra very important.Due to the particularity of incidence position, it is difficult for fixing, at cervical region operation technique repeatedly, easily make incidence displacement, activity simultaneously, be unfavorable for operation technique, especially in the situation that opening, canalis spinalis may cause spinal cord injury.And different cervical operations has different requirements for the range of flexion of stretching of cervical vertebra.So it is very important for cervical operation that stable fixing and rational cervical vertebra is stretched range of flexion.
Conventional cranial traction is that skull traction bow is fixed in patient's skull and implements to draw.The similar clamp-type bow of the structure body of skull traction bow, the main body of clamp-type bow body is two hinged circular arc clamping bars, the chuck position of clamping bar is provided with the draw point that inserts skull both sides, the bolt and nut that afterbody is provided with to adjustment chuck openings of sizes of caliper body, screw rod passes clamp two unthreaded holes of afterbody, adjust two nuts, thereby adjust and fixed chuck openings of sizes, on clamp-type bow body, be also provided with the pull bar that connects weight.There are the following problems for this method: 1, the inclined to one side calvarium in draw point position, draw when stressed, and draw point easily comes off from skull;
2, for regulating different cervical vertebras to stretch its operation inconvenience of range of flexion; 3, draw point is strained and fixed, and what lean on is that bolt and nut regulates, and when patient is movable, nut is easily loosening, and fixing unreliable, three-dimensional regulates and cannot realize, and in use needs to transfer to go, and easily produces danger.The method of visible employing draw point insertion skull is both dangerous also inconvenient.
Summary of the invention
This utility model aims to provide a kind of adjustable skull traction frame of simple, easy to operate, fixation being installed and can meeting different requirements of operation.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
A kind of adjustable skull traction frame, comprise the angle regulator being fixed on edge of bed, described angle regulator also by they sup-port in ground, and on angle regulator, be hinged with the towing bracket that can rotate to it, described towing bracket far-end is provided with fixed pulley; Also comprise lamina externa cranii, skull traction bow and pull rope, described lamina externa cranii can mate patient's lower jaw and skull both sides ear temple, described lamina externa cranii is fixedly connected with skull traction bow along calvarium direction, described pull rope is walked around fixed pulley, one end connects skull traction bow, and the other end connects traction element.
Adopt the utility model of technique scheme, by traction element, draw lamina externa cranii, thereby immobilized patients incidence, prevent from occurring that shift affects operates in operation, regulate the position change traction hight of towing bracket rotation simultaneously, thereby realize the adjusting that cervical vertebra is stretched to range of flexion, meet different cervical operations for the requirement of cervical curvature.
Further limit, described angle regulator is fastened on edge of bed by U-shaped draw-in groove, and is bolted.Adjustable towing bracket and operation table are separate, by U-shaped draw-in groove and edge of bed, complete interim clamping, and while needing, interim installation fixed, and while not needing, can take off easily, meets different requirements of operation, do not take redundant space.
Further limit, described angle regulator is controlled the rotation of towing bracket by hand turbine rod.Hand-rail type turbine rod controls that altitude mixture control is more common on medical apparatus and instruments, and this easily grasps operator, reduces because causing operate miss to equipment is not yet done.
This utility model is simple to operate compared to existing technology, fixation, can adapt to different patients and cervical vertebra be stretched to the requirement of range of flexion, turbine and worm structure has auto-lock function, this just makes not need extra mechanism's locking when regulating towing bracket angle, safe and simple effective, and easy installation and removal, while not needing, can remove at any time and save operating-table space.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is using state figure of the present utility model.
The specific embodiment
In order to make those skilled in the art understand better this utility model, below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated.
As shown in Figure 1 and Figure 2, a kind of adjustable skull traction frame, comprise the angle regulator 3 being fixed on edge of bed, when this angle regulator 3 is fastened on edge of bed by U-shaped draw-in groove 6, also by support bar 4, be supported in ground, angle regulator 3 can be located better like this, is hinged with the towing bracket 5 that can rotate to it on angle regulator 3, wherein towing bracket 5 near-ends are hinged on angle regulator 3 by rotating shaft, and far-end is provided with fixed pulley 51.
Patient, also need fixedly lamina externa cranii 1 with it, this lamina externa cranii 1 can mate patient's lower jaw and skull both sides ear temple, prevent that patient's skull from skidding off from lamina externa cranii, at lamina externa cranii 1, along calvarium direction, be fixedly connected with skull traction bow 2, this skull traction bow 2 forms closed hoop with lamina externa cranii 1, skull traction bow 2 tops connect pull rope 7, and this pull rope is walked around after fixed pulley 51, by connecting traction element 8, produce pull strength.
For the safer insurance of patient, skull traction bow 2 two ends can be fixed on skull by draw point, and skull traction bow 2 is hinged with lamina externa cranii 1 junction like this.Traction element 8 can adopt such as the counterweight device that can regulate pull strength size, by selecting the counterweight of Different Weight to regulate different pull strengths.
Described angle regulator 1 is controlled the rotation of towing bracket 5 by hand turbine rod 31, its concrete structure is that the driving gear 32 on hand turbine rod 31 is with the driven gear 33 of the towing bracket 5 that is dynamically connected to rotate.
This skull traction frame operation principle is as follows: first by lamina externa cranii 1, fix patient's lower jaw and skull both sides ear temple, then regulate the position of U-shaped draw-in groove 6 and bolt to be fixed in edge of bed, guarantee patient's skull both sides stress equalization when being pulled, avoid incidence left avertence or right avertence, skull traction bow 2 is fixed on lamina externa cranii 1 along in the direction of calvarium, pull rope 7 is connected with skull traction bow 2 tops, then pull rope 7 is walked around the fixed pulley 51 of towing bracket 5 far-ends, tail end adds that the weight of approrpiate wts forms traction element 8, said structure is by conduction traction the immobilized patients incidence of power.In order to meet different cervical operations, for cervical vertebra, stretch the requirement of range of flexion, can regulate hand turbine rod 31 to change traction hight and the lead of towing bracket 5, thereby realize the adjusting that cervical vertebra is stretched to range of flexion.Not the used time, untie U-shaped draw-in groove 6 and take off skull traction frame.
The adjustable skull traction frame above this utility model being provided is described in detail.The explanation of specific embodiment is just for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; do not departing under the prerequisite of this utility model principle, can also carry out some improvement and modification to this utility model, these improvement and modification also fall in the protection domain of this utility model claim.
