Description
Technical field
The present invention relates to the medical apparatus, relate in particular to that the cervical vertebra postoperative resets, the device of orthopedic auxiliary treatment.
Background technology
At present, the traction therapeutic of humans and animals under cervical vertebra unstability damage (fracture of cervical vertebra, dislocation, odontoid fracture, atlantoaxial dislocation, dislocation of cervical vertebra companion articular process interlocking etc.) and the pathological state that causes thus continued to use cranial traction mostly in the world wide.Cranial traction is the skull traction bow to be fixed on implement traction on the patient's skull.The similar clamp-type bow of the structure of skull traction bow body; The main body of clamp-type bow body is two hinged circular arc clamping bars, and the chuck position of clamping bar is provided with the draw point that inserts the skull both sides, the bolt and nut that is provided with afterbody adjustment chuck openings of sizes of caliper body; Screw rod passes clamp two unthreaded holes of afterbody; Adjust two nuts, thereby adjustment and fixed chuck openings of sizes also are provided with the pull bar that connects weight on the clamp-type bow body.
China, also adopted above-mentioned skull traction bow, and has designed bedside traction shelf when treating fracture-dislocation of cervical spine clinically in the eighties in last century, and both are used.Though above-mentioned skull traction bow is generally adopted, and has following defective: 1, the draw point of skull traction bow and the center line angle of bow are vertical configuration, and after traction was stressed, draw point very easily skidded off from skeleton, make the traction failure; 2, draw point is a common nails shape, can not be directly to the marrow, need to insert again behind sphenotresia with drill bit earlier, and locate inaccurately, be prone to cause the injury of patient's secondary, operate very complicacy; 3, draw point is strained and fixed, and what lean on is that bolt and nut is regulated, and nut was prone to looseningly when the patient was movable, and fixing unreliable, three-dimensional is regulated and can't be realized, in use need transfer to go, and is easy to generate danger; 4, the size of traction bow can not be according to the size adjustment of patient's head, and some uses and is not suitable for head dummy, the risk that comes off height; Can't grasp the size of stressed horizontal level and pulling force when 5, drawing, influence therapeutic effect; 6, because some nursing bed does not design the head of a bed, can't the fixed traction weight.
Summary of the invention
For solving the problems referred to above that existing skull traction bow exists in use, the present invention improves on the basis of existing skull traction bow, has proposed a kind of hand adjustable type skull traction device.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of hand adjustable type skull traction device; It comprises a clamp-type bow body; The main body of clamp-type bow body is two hinged circular arc clamping bars; The chuck portion of clamping bar is provided with the draw point that inserts skull, and the screw rod and the nut that are provided with afterbody adjustment chuck openings of sizes of caliper body also are provided with the pull bar that connects weight on the clamp-type bow body; It is characterized in that described draw point is the taper bolt pin, the bolt needle section is towards the inboard oblique upper of bow portion, and gradient is the 20-25 degree; One end of described screw rod is provided with bulb; The other end is provided with hand crank; Be provided with the bulb bowl that cooperates with bulb of caliper body on tail; On another tail of caliper body, be provided with the female thread that cooperates with screw rod, screw rod is assembled together afterbody through bulb and female thread and clamp, and chuck openings of sizes adjustment back is with above-mentioned nut check.
Bend stressed out-of-level problem in order to have overcome existing skull traction, on clamp-type bow body, air level is installed; Avoid the injury that the patient is caused by force unbalance.
In order to make the traction bow can be according to the size adjustment of patient's capitiform, above-mentioned circular arc clamping bar be designed to drawing and pulling type, and drawing structure is that the circular arc clamping bar overlaps by two sections, establishes some adjustment hole on the clamping bar, is bolted together through the adjustment hole.
Pulling force size when drawing in order to grasp is provided with the pulling force display device on pull bar, for example spring scale is used in the most easy pulling force display device.
In order to cooperate the nursing bed that does not design the head of a bed to use, it also comprises a bed head frame, and the structure of bed head frame is, at one pulley is installed above the gate, and two lower limbs of gate are provided with the turning type, and socket is provided with hands and twists bolt; During use socket is inserted on the bed board, with hands twist bolt tighten fixing, the fixed form of similar table tennis net.
During use, earlier patient's head is all shaved light and clean, let the patient lie on the back, head is just put; Make an accurate selection of boring position, skull both sides, do a kerf after the local anesthesia, the openings of sizes of adjustment skull traction bow snaps in head; Then taper bolt is directed against accurate otch, directly screws in skull, when the degree of depth reaches requirement, shake hand crank; Two clamping bars are clamped, and the reuse locking nut is fixed, and is connected with weight through bed head frame after fixing again, and just can draw.
The good effect of this device is: directly screw in skull through the taper bolt pin, and accurate positioning, and also the taper bolt pin has constant slope; A similar hook catches on skull, through the syndeton of screw rod and female thread, can not produce loosening again; The not redeformation of traction bow opening; And can regulate at any time and add tightness, guaranteed and the fixation of patient's head, avoid the skull traction bow in case stressed slippage to the secondary injury of patient's skull, cervical vertebra; Overcome skull traction through the installation air level and bent stressed out-of-level problem; Drawing and pulling type structure through clamping bar can be according to the size adjustment of patient's capitiform; Make fixed more reliable: through the pulling force display device; Pulling force size in the time of grasping traction makes patient's rehabilitation as early as possible: through custom-designed bed head frame, can cooperate the nursing bed that does not design the head of a bed to use; For the use of medical institutions brings convenience, help the popularization of skull traction technology clinically.
