Abstract
The utility model discloses an auto-stop cranium drill which is used for the craniotomy of neurosurgery in the hospitals. The utility model mainly comprises a hand holding electric drill, and the drill bit of an auto-stop cranium drill, wherein, the drill bit of the auto-stop cranium drill comprises a cranium main drilling knife, an assistant limiting drilling knife, a connecting bar for drilling knives, an engaging and disengaging main body, a top ball spring, and a connecting bar for drilling bits. The main drilling knife is connected with the engaging and disengaging main body of the drilling knife by the pressure of craniums to the hand holding electric drill when the auto-stop cranium drill is twisted, and the main drilling knife is separated from the engaging and disengaging main body of the drilling knife under the action of the spring when the main drilling knife drills the cranium to stop the main drilling knife. The utility model has the advantages that the safety of craniotomy is ensured; the work efficiency is enhanced accordingly.
Description
This utility model relates to a kind of medical apparatus and instruments, and the used automatic stop cranium of sphenotresia bores during particularly a kind of hospital neurosurgery operation of opening cranium.
At present, generally all use front end band drill bit during hospital neurosurgery operation of opening cranium and the hand drill of afterbody band handle carries out sphenotresia, this hand drill operation is difficult for grasping, carry out the general complete experience of operation of opening cranium with surgical staff, can the patient harm meninges when executing when boring firmly the pin stool, cause malpractice, thereby use is absolutely unsafe.In addition, carry out sphenotresia also than effort, time-consuming with this kind hand drill, thereby work efficiency is also lower.
In view of the foregoing, the purpose of this utility model provides a kind of easy to use, safe and automatic stop cranium that can increase work efficiency and bores.
The purpose of this utility model is achieved in that it is made of with the automatic stop cranium drill bit that can be connected with this electric hand drill auger spindle common electric hand drill, this automatic stop cranium drill bit comprises the skull master and bores cutter, auxiliary spacing brill cutter, bore that cutter clutch main body and anterior and skull master bore that cutter is connected and brill cutter connecting rod that rear portion and brill cutter clutch main body inner wall are slidingly matched and be located at and bore the decorative pearl on top of an official cap and the spring that can make brill cutter connecting rod telescopic slide in the cutter clutch main body, auxiliary spacing brill broach shell bores the outside at cutter rear portion the skull master, its afterbody with recessed tooth and skull master bore the cutter afterbody with double wedge be meshed, the front-end and back-end of boring cutter clutch main body have respectively be convenient to the skull master bore the cutter afterbody with double wedge recessed tooth that is meshed and the drill bit connecting rod of being convenient to be connected with the electric hand drill auger spindle.During use, the skull master is bored cutter bore skull hole spots localization at need, and the pressure of additional 3-5 kilogram, press the press button of electric hand drill simultaneously, the auger spindle of electric hand drill is rotated, be meshed with bore cutter clutch main body recessed tooth owing to the skull master bores the cutter double wedge this moment, forces the skull master to bore cutter rotation and cutting forward.When cranial drill saturating, and when not touching meninges, because the effect of decorative pearl on top of an official cap spring, make the main cutter double wedge that bores leave brill cutter clutch main body, auxiliary spacing brill cutter blocks on the skull stage, makes the master bore cutter and stops immediately to bore with auxiliary spacing brill cutter, at this moment the release button switch, the electric drill stall, thus whole actions of sphenotresia finished.
Characteristics of the present utility model are when cranial drill is saturating, and boring cutter can stop operating automatically, thereby is difficult for the meninges of patient harm, helps safety operation, and are also more laborsaving simultaneously, save time.
Embodiment of the present utility model is provided by the following drawings:
Fig. 1 is this utility model external overall structural representation.
Fig. 2 is an automatic stop cranium drill bit structural representation.
Each exploded view among Fig. 3 Fig. 2.
By accompanying drawing as can be known, this utility model by common electric hand drill 2(owing to be known technology, so its internal structure is omitted and is drawn) and automatic stop cranium drill bit 1 two parts constitute, wherein automatic stop cranium drill bit 1 by the skull master bore cutter 3, auxiliary spacing brill cutter 4, bore cutter connecting rod 5, brill cutter clutch main body 6, the decorative pearl on top of an official cap 7, spring 8 and drill bit connecting rod 9 constitute.Auxiliary spacing brill cutter 4 is enclosed within the outside that the skull master bores cutter 3, and its afterbody is with recessed tooth and skull master to bore cutter 3 double wedges that afterbody is with to be meshed; Brill cutter connecting rod 5 front portions are bored cutter 3 with the skull master and are threaded, and the rear portion is slidingly matched with brill cutter clutch main body 6 inwalls; The decorative pearl on top of an official cap 7 and cover spring 8 thereon are located at the afterbody that bores in the cutter clutch main body 6 and place brill cutter connecting rod 5; The front end that bores cutter clutch main body 6 is provided with is convenient to the recessed tooth that is meshed with main brill cutter 3 double wedges, the rear end drill bit connecting rod 9 that is threaded, and this connecting rod can link to each other with the auger spindle 10 in the electric hand drill 2.Rely on skull when executing brill and the main cutter 3 that bores is meshed with brill cutter clutch main body 6 the additional pressure of electric hand drill, when main brill cutter 3 bores saturating skull, then rely on decorative pearl on top of an official cap spring 7,8 will lead brill cutter 3 and separate, and make the stall immediately of brill cutter by the auxiliary spacing brill cutter 4 that is stuck on the skull stage with brill cutter clutch main body 6.
In order to guarantee that boring cutter connecting rod 5 rear portions freely stretches in boring cutter clutch main body 6, can on brill cutter clutch main body 6, the fuel feed hole 11 that can annotate sterilization lubricating oil in it be set.
