Abstract
The utility model relates to a controllable cervical vertebrae trepan, which is used for medical clinical use. The utility model is characterized in that the front end of a trepan is provided with saw teeth, forward saw teeth and backward saw teeth are laid with intervals, the back end of a trepan is provided with a handle, a trepan tube is provided with a longitudinal slide slot, a slide core rod is arranged in the trepan tube, the slide core rod is corresponding to the slide slot, the slide core rod is provided with a spacing bone block piece and a locating piece, and the front section of the trepan tube is marked with scales. The utility model has the advantages of reasonable structure, convenient operation, good operation field for carrying out operation, time saving, labor saving, accuracy control, ensured operation quality, reduced operation risk and reduced patient's pain.
Description
This utility model relates to a kind of controllable type cervical vertebra trepan, belongs to medical apparatus and instruments.
Will use the cervical vertebra trepan in the cervical spondylosis operative treatment, use that the cervical vertebra trepan needs strictness, accurately control pierces the degree of depth, otherwise the easy damaged spinal cord causes serious quadriplegia, severe patient more, even life danger appears.And in use there is inconvenience in existing cervical vertebra trepan, can not satisfy this requirement well, and directly influence operation quality strengthens doctor and patient's operation risk, increases patient's misery.
The purpose of this utility model is to provide a kind of controllable type cervical vertebra trepan, and is easy to use, and easily accurately control guarantees the operation quality easily, reduces operation risk, alleviates patient's misery.
Controllable type cervical vertebra trepan described in the utility model, the front end of trepan cylinder is a sawtooth, the rear end is a handle, one vertical chute is arranged on its trepan cylinder, one sliding core pole corresponding with chute arranged in the trepan cylinder, and sliding core pole is provided with limiting bone block and positioning mounting, and the leading portion of trepan cylinder is marked with scale.
Pierce degree of depth requirement according to operation, mobile sliding core pole has been determined the position of limiting bone block by reference mark, with sliding core pole and trepan cylinder relative fixed, can implement operation by positioning mounting.When piercing the degree of depth and reach requirement, limiting bone block can play barrier effect, stops to continue to pierce, and has guaranteed to pierce accurately the degree of depth, has guaranteed the operation quality, has reduced operation risk, has reduced patient's misery.In this utility model, sliding core pole also can play certain position-limiting action, guarantees that further operation pierces the degree of depth.Can be embedded fastening structure between limiting bone block and sliding core pole, can be fixed together between the two, also can throw off.Both throw off, and the sliding core pole reach can be with the complete release of bone core that pierces.Use this utility model operation that undergos surgery, surgical field of view is good, is convenient to operation and carries out, and is beneficial to and improves the quality of performing the operation.
For simplified structure, handled easily is designed to positioning mounting to be made up of screw rod, nut, and screw rod is fixedlyed connected with sliding core pole, and nut is spun on the screw rod that stretches out chute.Nut is screwed, can be together with trepan cylinder and sliding core pole relative fixed.
The sawtooth of trepan cylinder is forward tooth, the oppositely alternate layout of tooth, so forward, reverse rotation handle in this utility model, and all can undergo surgery pierces, time saving and energy saving, shortens operating time, improves the operation quality, reduces patient's misery.
Below in conjunction with the embodiment accompanying drawing this utility model is further described.
Fig. 1, this utility model-example structure sketch map.
Among the figure: 1 sawtooth, 2 trepan cylinders, 3 chutes, 4 limiting bone blocks, 5 sliding core poles, 6 nuts, 7 screw rods, 8 handles, 9 scales.
As shown in the figure, controllable type cervical vertebra trepan described in the utility model, the front end of trepan cylinder 2 is a sawtooth 1, forward tooth, the reverse alternate layout of tooth, and the rear end is a handle 8, one vertical chute 3 is arranged on the trepan cylinder 2, one sliding core pole 5 corresponding with chute 3 arranged in the trepan cylinder 2, the positioning mounting that sliding core pole 5 is provided with limiting bone block 4 and is made up of screw rod 7, nut 6, screw rod 7 is fixedlyed connected with sliding core pole 5, nut 6 is spun on the screw rod 7 that stretches out chute 3, and the leading portion of trepan cylinder 2 is marked with scale 9.
During use, pierce degree of depth requirement according to operation, mobile sliding core pole 5 by the position of reference mark 9 definite good limiting bone blocks 4, with sliding core pole 5 and trepan cylinder 2 relative fixed, can be implemented operation by setscrew nut 6.When piercing the degree of depth and reach requirement, limiting bone block 4 just plays barrier effect.Take out trepan, continue to pass sliding core pole 5 forward, the bone core can be released.
This utility model is rational in infrastructure, uses easy to operately, and surgical field of view is good, is convenient to operation and carries out, and is time saving and energy saving, and easily accurately control has guaranteed the operation quality again, has reduced operation risk, can alleviate patient's misery, is beneficial to clinical application.
Claims (3)
