Abstract
The utility model discloses a skull milling cutter. The skull milling cutter comprises a handheld type cutter body and a skull milling head. The handheld type cutter body is composed of a direct-current motor, a transmission and a shell. The skull milling head is connected with an output end of the transmission through a connector. The other end of the transmission is connected with the direct-current motor through the connector. A protective boot is arranged at the front end of the handheld type cutter body. The bottom of the protective boot is connected to the shell. A guiding hole is formed in the front end portion of the protective boot. A cavity tube is arranged in a rod body of the protective boot. Two ends of the cavity tube are respectively communicated with a water dripping hole and a water inlet. The water dripping hole is formed in one side facing the skull milling head above the guiding hole. The water inlet is formed in the bottom of the protective boot and is connected with a water ripping device through a pipeline. The pipeline penetrates out of the tail portion of the cutter body through the handheld type cutter body. A water dripping control switch is arranged on a handle of the handheld type cutter body. The water dripping hole is formed in the milling head to lead to speed-controlled dripping free of flushing, thus heat generated from the milling cutter is effectively reduced, and operational efficiency and quality are improved.
Description
Technical field
This utility model relates to a kind of skull milling cutter, belongs 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 in the utility model 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, this utility model 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: this utility model is installed 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.The utlity model has advantage simple in structure, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that this utility model 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, this utility model is specifically described.
Figure 1 shows that structural representation of the present utility model.
This utility model comprises hand-held fuselage 1 and the skull milling head 2 consisting of direct current generator, variator and casing, 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.
Embodiment of the present utility model
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 utility model: during this utility model work, on one side the milling head by high speed rotating cuts skull, simultaneously 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.
This utility model is installed 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.The utlity model has advantage simple in structure, easy to use.
The above-mentioned embodiment of this utility model, just illustrates, and is not only, all within the scope of this utility model or the change being equal in scope of the present utility model all by this utility model, surrounded.
