Abstract
The utility model discloses a skull drill for craniotomy, which is composed of a drill body, a main drill knife, a drill bit body and a quick connector. The quick connector is composed of a connection body, an outer sleeve body, a spring, a steel ball and a guiding slide head. One end of the connector is connected with the drill bit body, and the other end is connected with the drive shaft of the drill body. The spring and the guiding slide head are sheathed on the outside circle of the connector, and the outer sleeve body is sheathed on the spring and the guiding slide head. The utility model has the advantages of simple structure, easy operation, and safety. Once the main drill knife disclosed by the utility model is arranged, the utility model can be characterized in accurate positioning, smooth cutting, quick chip removing and labor-saving drilling application, and the utility model is an ideal skull drill.
Description
This utility model relates to the cranial drill that the neurosurgery operation of opening cranium of a kind of hospital is used, and belongs to surgical medical equipment.
At present, the doctor is when doing the neurosurgery operation of opening cranium, what generally use all is that soft power transmission shaft drives craniotome, promptly connect handle clamping skull drill bit by one section long soft power transmission shaft, this soft transmission shaft type cranial drill operation is difficult for grasping, and needs to rely on the experience of operative doctor, if careless slightly, will cause the serious consequence of damage meninges, therefore have unsafe factor.Also have and a kind ofly carry out sphenotresia, do not meeting safety requirements like this with exchanging jackhammer clamping cranial drill.
The purpose of this utility model provides between a kind of drill bit and the handle has fast interface, and portable cranial drill simple in structure, safe and reliable, to overcome the deficiencies in the prior art.
The purpose of this utility model is achieved in that by portable drill body, the main portable cranial drill that bores cutter and skull bit body composition, be provided with quick connector between drill body and the skull bit body, quick connector is by connector, outer sleeve body, spring, steel ball and guiding slide head are formed, connector is that a center has axis hole, cylindrical has the spacing end face and the cylinder of spacing hole radially, the one end is connected with the skull bit body, have on the cylindrical of axis hole one end and be with spring by spacing end, the guiding slide head is enclosed within the radially spacing hole place on the connector cylindrical, contact with spring, radially be provided with steel ball in the spacing hole, outer sleeve body is enclosed within connector, the moving foxy outside of spring and guiding.
This utility model is simple in structure, and processing ease is safe and reliable.If select the main cutter that bores provided by the utility model, more can make the skull accurate positioning, stable cutting, chip removal is fast, and it is laborsaving to execute brill.
Fig. 1 is an external overall sketch map of the present utility model.
Fig. 2 is a fast interface cranial drill head assembly structural representation of the present utility model.
Fig. 3 is the main sketch map that bores cutter of the present utility model.
Fig. 4 is the left view of Fig. 3.
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, portable cranial drill is made up of portable drill body (1) and fast interface cranial drill head assembly.Fast interface cranial drill head assembly comprises main cutter (3), skull bit body (4) and the quick connector (2) of boring.The main cutter (3) that bores is positioned on the interior guide rail of skull bit body (4).The main cutter (3) that bores can adopt existing technology, also can adopt structure as shown in Figure 3, Figure 4, be that the wide b of chisel edge is 0.03D (D is the main diameter that bores cutter (3)), chisel edge angle ψ is 55 °～65 °, end face cutting edge inclination τ is 20 °～25 °, and it is 0.03D that the end sword is higher than cutting edge h, and cutting edge angle α is 140 °～160 °, sharp angle β is 100 °～120 °, and arc groove radius R is 1～1.5mm.The afterbody of skull bit body (4) is connected with an end of connector (5), the other end of connector (5) has central shaft hole, cylindrical is provided with spacing end face, and have a radially spacing hole, be with spring (7) in the spacing end of cylindrical, radially the spacing hole place is with guiding slide head (9), and guiding slide head (9) contacts with spring (7), radially is provided with steel ball (8) in the spacing hole.The outside at connector (5), spring (7) and guiding slide head (9) is with outer sleeve body (6).
When connecting skull bit body assembly and drill body (1), the direction of outer sleeve body (6) to skull bit body (4) moved, guiding slide head (9) is in company with displacement, and compression spring (7) is when guiding slide head (9) moves to the position of leaving steel ball (8), the power transmission shaft of drill body (1) is inserted in the central shaft hole of connector (5), and make it to put in place, unclamping outer sleeve body (6), spring (7) resets, promote guiding slide head (9) and move, and push down steel ball (8) and lock with power transmission shaft and be connected.
By same principle, with cranial drill head assembly and drill body (1) split.
Claims (2)
