Abstract
The invention discloses a skull milling cutter. The skull milling cutter comprises a handheld machine body composed of a direct-current motor, a speed changer and a machine shell and a skull milling head, wherein the skull milling head is connected with the output end of the speed changer through a connector; the other end of the speed changer is connected with the direct current motor through another connector; a protective boot is arranged at the front end of the handheld machine body; the bottom of the protective boot is connected with the machine shell; a guide hole is formed in the front end part of the protective boot; a cavity pipe is arranged in the rod body of the protective boot; the two ends of the cavity pipe are respectively communicated with a water dropping hole and a water inlet; the water dropping hole is formed in one side, facing to the skull milling head, above the guide hole; the water inlet is formed in the bottom of the protective boot; the water inlet is connected with a water dropping device through a pipeline; the pipeline passes through the handheld machine body and penetrates out of the tail part of the machine body; a water dropping control switch is arranged at the handle of the handheld machine body. According to the skull milling cutter, a water dropping opening is formed in the milling head to replace flushing, and the water dropping speed can be regulated and controlled, so that the quantity of heat generated by the milling cutter is effectively reduced, and the efficiency and quality of operations are improved.
Description
Technical field
The present invention relates to a kind of skull milling cutter, belong to technical field of medical instruments.
Background technology
Skull milling cutter is the conventional operation of opening cranium apparatus of neurosurgery, when carrying out cerebral surgery operation, by the milling head incision skull of high speed rotating.In prior art because milling cutter high speed rotating produces amount of heat, milling cutter is easily caused damage, fractureed, the heat producing also can cause damage to cranium cerebral tissue, therefore need another assistant to continue to rush normal saline with distribute heat, increased on the one hand staff's workload, operation is also inconvenient on the other hand, and because the reason coordinating is dripped inhomogeneous, cooling-down effect is unsatisfactory, milling cutter fracture and meninges high temperature under melt and happen occasionally.Impact operation quality and speed.
Summary of the invention
Technical problem to be solved by this invention is the defect existing for prior art, and a kind of neurosurgery skull milling cutter easy to use is provided.
For solving this technical problem, the invention provides a kind of skull milling cutter, comprise by direct current generator, hand-held fuselage and skull milling head that variator and casing form, described skull milling head is connected with the outfan of variator by adapter, the other end of variator is connected by adapter with direct current generator, at the front end of hand-held fuselage, be provided with and protect boots, the bottom of protecting boots is connected in casing, protect boots leading section and be provided with pilot hole, in the described shaft that protects boots, be provided with a cavity pipe, the two ends of this cavity pipe are UNICOM's weeper and inlet opening respectively, described weeper is positioned at pilot hole top towards skull milling head one side, described inlet opening is positioned at protects boots bottom, inlet opening is connected with dripping device by pipeline, described pipeline passes at afterbody through hand-held fuselage, handle place at hand-held fuselage is provided with the gauge tap that drips.
Between weeper and inlet opening, be also provided with 1-2 weeper.
The aperture of a plurality of weepers then increases successively from front.
Described dripping device comprises liquid storage pump and the quantitative control device that normal saline is housed, and the gauge tap that drips is connected with quantitative control device.
Beneficial effect: the present invention installs water dropping openings at milling head position, replace bath, to milling cutter good cooling effect; Before, during and after blank pipe chamber, be provided with a plurality of weepers, and weeper then increases successively from front, water outlet is even, and speed of dropping water can arbitrarily regulate and control according to practical situation, effectively reduces the heat that milling cutter produces, and has improved efficiency and the quality of operation.It is simple in structure, easy to use that the present invention has advantages of.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation that the present invention protects boots.
In figure: 1 hand-held fuselage, 2 skull milling heads, 3 protect boots, 4 pilot holes, 5 cavity pipes, 6 weepers, 7 inlet openings, 8 drip gauge tap, 9 pipelines.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is specifically described.
Figure 1 shows that structural representation of the present invention.
The present invention includes the hand-held fuselage 1 and the skull milling head 2 that by direct current generator, variator and casing, are formed, described skull milling head 2 is connected with the outfan of variator by adapter, the other end of variator is connected by adapter with direct current generator, at the front end of hand-held fuselage 1, be provided with and protect boots 3, the bottom of protecting boots 3 is connected in casing, protects boots 3 leading sections and is provided with pilot hole 4.
In the described shaft that protects boots 3, be provided with a cavity pipe 5, the two ends of this cavity pipe 5 are UNICOM's weeper 6 and inlet opening 7 respectively, described weeper 6 is positioned at pilot hole 4 tops towards skull milling head 2 one sides, and described inlet opening 7 is positioned at protects boots 3 bottoms, and inlet opening 7 is connected with dripping device by pipeline 9.
Described pipeline 9 passes at afterbody through hand-held fuselage 1, at the handle place of hand-held fuselage 1, is provided with the gauge tap 8 that drips.
Described dripping device comprises liquid storage pump and the quantitative control device that normal saline is housed, and the gauge tap 8 that drips is connected with quantitative control device.
Embodiments of the invention
Between weeper 6 and inlet opening 7, be also provided with 1-2 weeper 7.
The aperture of a plurality of weepers 7 then increases successively from front.
Operation principle of the present invention: when the present invention works, on one side milling head by high speed rotating skull is cut, by the dripping of the on-off control weeper that drips, along with splashing into of normal saline, the temperature of milling head has just fallen, and realizes the effect of cooling simultaneously.
The present invention installs water dropping openings at milling head position, replace bath, to milling cutter good cooling effect; Before, during and after blank pipe chamber, be provided with a plurality of weepers, and weeper then increases successively from front, water outlet is even, and speed of dropping water can arbitrarily regulate and control according to practical situation, effectively reduces the heat that milling cutter produces, and has improved efficiency and the quality of operation.It is simple in structure, easy to use that the present invention has advantages of.
The above-mentioned embodiment of the present invention, just illustrates, and is not only, and change within the scope of the present invention all or that be equal in scope of the present invention is all surrounded by the present invention.
