Abstract
The utility model discloses a craniotomy drill main machine. The craniotomy drill main machine comprises a handle (1) at the lower part and an accommodating part (2) at the upper part, the stator and the rotor (5) of a direct current motor are arranged in the accommodating part, the wall (4) of the accommodating part (2) serves as a casing of the stator of the direct current motor, a baffle (6) with a hole is arranged at the rear part of the accommodating part (2), and an end cover (3) is hermetically connected with the rear end of the accommodating part (2) through screw threads; and a conductor on the stator of the direct current motor passes through the hole on the baffle (6) and enters the interior part of the handle (1). The craniotomy drill main machine has a simple structure, and takes the wall of the accommodating part directly as the casing of the stator of the direct current motor, so that the volume is reduced, and the whole weight is lightened; the sliding phenomenon of the motor is avoided, therefore the safety performance is higher; and the adoption of the integrative design, the waterproof material and the waterproof technology enables the waterproof performance of the craniotomy drill main machine to be better.
Description
Technical field
This utility model relates to the bone drill motor that a kind of surgical operation uses.
Background technology
In surgical operation, drill for craniotomy is the cranium instrument of opening comparatively commonly used.Drill for craniotomy comprises main frame, decelerator, locking bed and drill bit, and main frame comprises that again the bottom has handle, top has the housing of cylindric accommodation section and is motor cylindraceous.During assembling, motor need be filled in the accommodation section cavity of housing top cylindrical tube shape, then with holding out against the screw fixed electrical machinery.But this structure has caused the upper volume of housing bigger, has increased the overall weight of drill for craniotomy, simultaneously, after having grown service time, holds out against screw and becomes flexible, and motor can skid off from container cavity, has an accident when causing operation easily.
The utility model content
The purpose of this utility model provides little, the lightweight drill for craniotomy main frame of a kind of volume.
To achieve these goals, by the following technical solutions:
A kind of drill for craniotomy main frame comprises the handle of bottom and the accommodation section on top, has the stator and the rotor of direct current generator in the accommodation section, it is characterized in that: the wall of described accommodation section is the shell of DC motor stator.
For the ease of deriving in the line set in the stator, the rear portion of described accommodation section is provided with baffle plate with holes, and end cap is connected with the accommodation section back-end sealing by screw thread; Lead on the described DC motor stator passes the hole on the baffle plate, enters handle inside.
For waterproof, be provided with watertight composition on the lead in the described DC motor stator.
Of the present utility model simple in structure, directly as the shell of motor stator, reduced volume with the wall of accommodation section, alleviated overall weight.Motor landing phenomenon can not occur, security performance is higher.The use of incorporate design simultaneously and waterproof material, technology, water resistance is better.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment;
Fig. 2 is the right view of Fig. 1;
Fig. 3 be among Fig. 1 A-A to view.
The specific embodiment
Below in conjunction with drawings and the specific embodiments this utility model is described further:
As Fig. 1 and shown in Figure 3:
A kind of drill for craniotomy main frame comprises the handle 1 of bottom and the accommodation section 2 on top, has the stator and the rotor 5 of direct current generator in the accommodation section 2, and the wall 4 of accommodation section 2 is the shell of DC motor stator.The rear portion of accommodation section 2 is provided with baffle plate with holes 6, and accommodation section 2 is divided into former and later two cavitys, and the front inside cavity is provided with motor stator, and end cap 3 is connected with accommodation section 2 back-end sealings by screw thread; Lead on the DC motor stator passes the hole on the baffle plate 6, through entering handle 1 inside behind the cavity at rear portion again.Be provided with watertight composition on the lead in the DC motor stator.
The above; only be embodiment of the present utility model; be not to any pro forma restriction of the present utility model; any those skilled in the art; in the scope that does not break away from technical solutions of the utility model; when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations; in every case be not break away from the technical solutions of the utility model content; to any simple modification, equivalent variations and modification that above embodiment did, all still belong to the scope of technical solutions of the utility model protection according to this utility model technical spirit.
Claims (3)
1. a drill for craniotomy main frame comprises the handle (1) of bottom and the accommodation section (2) on top, has the stator and the rotor (5) of direct current generator in accommodation section (2), and it is characterized in that: the wall (4) of described accommodation section (2) is the shell of DC motor stator.
2. drill for craniotomy main frame as claimed in claim 1 is characterized in that: the rear portion of described accommodation section (2)
