Description
Technical field
The present invention relates to medical instruments field, more particularly to a kind of soft brill spring.
Background technology
In bone surgery, when needing to fastened by screw, corresponding rising is coordinated usually using electric screw driver or Pneumatic screw driver
Sub- head is by screw tightening.But special circumstances can be usually run into, due to special angles and positions, in irregular and fragile people
In body structure, batch mouth on electric screw driver cannot be reached directly at the screw for needing to tighten, it is difficult to tighten.
The content of the invention
The present invention solves the technical problem of a kind of soft brill spring is provided, arbitrarily angled, cooperation electricity can be bent into
Dynamic bottle opener and screwdriver head, can fasten to the screw that turning or dead angle position etc. directly cannot be tightened with bottle opener.
In order to solve the above technical problems, one aspect of the present invention is：A kind of soft brill spring is provided, including：
Spring body, Screwdriver sleeve and connector, Screwdriver sleeve and connector are separately fixed at spring body two ends；The spring body
Including internal layer spring, sublevel spring, middle level spring and outer layer spring, sublevel spring is closely coated on internal layer spring outer wall, in
Layer spring is closely coated on sublevel spring, and outer layer spring is closely coated on the spring of middle level；The internal layer spring and sublevel bullet
Spring is oppositely oriented, and sublevel spring is oppositely oriented with middle level spring, and middle level spring is oppositely oriented with outer layer spring；The internal layer spring
By a spring filament winding into the pitch of internal layer spring is equal to the diameter of spring silk；Sublevel spring is coiled into side by side by two spring silks, sublevel bullet
The pitch of spring is equal to the double diameter of spring silk, and middle level spring is coiled into side by side by three spring silks, and the pitch of middle level spring is equal to spring silk
Three times diameter, outer layer spring is coiled into side by side by four springs silk, and the pitch of outer layer spring is equal to four times of diameters of spring silk.
Preferably, spring filament diameter of the central diameter of the internal layer spring less than 1.5 times.
Preferably, it is equipped with sleeve pipe on the Screwdriver sleeve and connector, the sleeve pipe of Screwdriver sleeve and connector covers respectively
At spring body two ends, the sleeve pipe of Screwdriver sleeve and connector is fastened on spring body by hydraulic means.
The beneficial effects of the invention are as follows：The screw that the present invention can directly cannot be tightened to turning or dead angle position etc. with bottle opener
Fastened.

Specific embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
Fig. 1 and Fig. 2 is referred to, the embodiment of the present invention includes：
A kind of soft brill spring, including：Spring body 1, Screwdriver sleeve 2 and connector 3, Screwdriver sleeve and connector are separately fixed at
Spring body two ends；The spring body includes internal layer spring 4, sublevel spring 5, middle level spring 6 and outer layer spring 7, sublevel bullet
Spring 5 is closely coated on the outer wall of internal layer spring 4, and middle level spring 6 is closely coated on sublevel spring 5, and outer layer spring 7 is closely coated
On middle level spring 6；The internal layer spring 4 is oppositely oriented with sublevel spring 5, and sublevel spring 5 is oppositely oriented with middle level spring 6,
Middle level spring 6 is oppositely oriented with outer layer spring 7；The internal layer spring is by a spring filament winding into the pitch of internal layer spring is equal to spring
The diameter of silk；Sublevel spring is coiled into side by side by two spring silks, and the pitch of sublevel spring is equal to the double diameter of spring silk, middle level spring
Be coiled into side by side by three springs silk, the pitch of middle level spring is equal to the three times diameter of spring silk, outer layer spring by four springs silks side by side around
Into the pitch of outer layer spring is equal to four times of diameters of spring silk.The central diameter of the internal layer spring is equal to spring filament diameter.The driver sleeve
Be equipped with sleeve pipe on cylinder and connector, the sleeve pipe of Screwdriver sleeve and connector is respectively fitted over spring body two ends, Screwdriver sleeve and
The sleeve pipe of connector is fastened on spring body by hydraulic means.
The present invention can be bent into arbitrarily angled, cooperation electric screw driver and screwdriver head, can be to the nothing such as turning or dead angle position
The screw that method is directly tightened with bottle opener is fastened, and difficulty and the time of the turn of the screw can be reduced in operation.
Embodiments of the invention are the foregoing is only, the scope of the claims of the invention is not thereby limited, it is every to utilize this hair
Equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills
Art field, is included within the scope of the present invention.
