Concrete technical scheme is as follows：

A kind of surgery intelligence drill bit device, including drill bit, push rod, the drill bit includes the first drill bit layer, is sheathed on institute The second drill bit layer outside the first drill bit layer, the 3rd drill bit layer being sheathed on outside the second drill bit layer is stated, by that analogy, until the Till N drill bit layers, wherein N is at least 3, and the first drill bit layer, the second drill bit layer are until the top of N-1 drill bit layers is equal The position-arresting ring of annular shape is arranged with, it is adjacent thereto that the second drill bit layer offers receiving up in the N drill bits layer The inner chamber of N-1 drill bit layers, the base diameter of the inner chamber are equal to the diameter of N-1 drill bit layers adjacent thereto, the inner chamber Diameter more than bottom is equal to the diameter of the position-arresting ring on N-1 drill bit layers adjacent thereto, and each drill bit layer is arranged successively The bottom of the drill bit after finishing is in turbination, and the push rod is fixed on the top surface of the drill bit, the push rod and institute State that drill bit is corresponding to be divided into N shell, N is at least 3, and described in each layer top of each layer diameter of the push rod and the drill bit only The equal diameters of position ring；

Preferably, the push rod has push rod motor to promote；

Preferably, screwed hole is provided with the correspondence position on per layer of drill bit.

Beneficial effect：

The design of multilamellar drill bit of this utility model by being arranged successively, is that doctor is brought using various sizes of drill bit It is convenient, save the quality time of surgical, mitigated the pain of patient.

Description of the drawings

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment Or accompanying drawing to be used is briefly described needed for description of the prior art, it should be apparent that, drawings in the following description are only It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise for not paying creative work Under, can be with according to these other accompanying drawings of accompanying drawings acquisition.

Fig. 1：The cross-sectional view of three layers of drill bit；

Fig. 2：First drill bit layer exited by push rod after cross-sectional view；

Fig. 3：First drill bit layer and the second drill bit layer exited by push rod after cross-sectional view；

Fig. 4：The dimensional structure diagram of three layers of push rod.

Reference is as follows：1st, drill bit, 2, push rod, the 3, first drill bit layer, the 4, second drill bit layer, the 5, the 3rd drill bit layer, 6, Position-arresting ring, 7, inner chamber, 8, screwed hole.

Specific embodiment

For making purpose, technical scheme and the advantage of this utility model embodiment clearer, below to this utility model reality The technical scheme applied in example is clearly and completely described, it is clear that described embodiment is that this utility model part is implemented Example, rather than the embodiment of whole.Based on the embodiment in this utility model, those of ordinary skill in the art are not making wound The every other embodiment obtained under the premise of the property made work, belongs to the scope of this utility model protection.

With reference to Fig. 2 to Fig. 4, referring to Fig. 1：A kind of surgery intelligence drill bit device, including drill bit 1, push rod 2, the drill bit 1 Including the first drill bit layer 3, the second drill bit layer 4 being sheathed on outside the first drill bit layer 3, it is sheathed on outside the second drill bit layer 4 The 3rd drill bit layer 5, by that analogy, till N drill bit layers, wherein N is at least 3, the first drill bit layer 3, described Two drill bit layers 4 are arranged with the position-arresting ring 6 of annular shape up to the top of N-1 drill bit layers, and the second drill bit layer 4 is until described Offer the inner chamber 7 of the N-1 drill bit layers for accommodating adjacent thereto in N drill bits layer, the base diameter of the inner chamber 7 equal to Adjacent N-1 drill bit layers diameter, diameter more than 7 bottom of the inner chamber be equal to N-1 drill bit layers adjacent thereto on The position-arresting ring 6 diameter, each drill bit layer is arranged the bottom of the drill bit 1 after finishing successively in turbination, described to push away Bar 2 is fixed on the top surface of the drill bit 1, and the push rod 2 is corresponding with the drill bit 1 to be divided into N shell, and N is at least 3, and described The equal diameters of each layer diameter of push rod 2 and the position-arresting ring 6 on each layer top of the drill bit 1；The push rod 2 has push rod to drive Dynamic motor pushing；Screwed hole 8 is provided with correspondence position on per layer of drill bit 1.

When doctor needs the drill bit using the diameter of the first drill bit layer 3, by the push rod motor Thrustor layer corresponding with the first drill bit layer 3 on the push rod 2 is promoted, and the first drill bit layer 3 is promoted along the drill bit 1 The direction of length move downward, the position-arresting ring 6 on 3 top of the first drill bit is to the institute in the second drill bit layer 4 Stop motion when stating in inner chamber 7；When doctor needs the drill bit using the diameter of the second drill bit layer 4, by described Push rod motor promotes thrustor layer corresponding with the second drill bit layer 4 on the push rod 2 and right with the institute of the first drill bit layer 3 simultaneously The thrustor layer answered, promotes the first drill bit layer 3 and the second drill bit layer 4 while downward along the direction of the length of the drill bit 1 Motion, stops when the position-arresting ring 6 on 4 top of the second drill bit layer is in the inner chamber 7 in the 3rd drill bit layer 5 Only move, meanwhile, it is installed on the screwed hole on the screwed hole 8 of the first drill bit layer 3 and the second drill bit layer 4 with bolt 8 securing the above the first drill bit layer 3 with the second drill bit layer 4；By that analogy, until N drill bit layers.

Only to illustrate the technical solution of the utility model, rather than a limitation；Although with reference to the foregoing embodiments to this reality It has been described in detail with new, it will be understood by those within the art that：Which still can be to foregoing embodiments Described technical scheme is modified, or carries out equivalent to which part technical characteristic；And these are changed or replace Change, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of this utility model.
