Abstract
The utility model relates to a medical bone drill guiding protector with depth measurement with the functions of guiding, depth probe and protecting. The protector is used for bone drilling. The protector comprises a sleeve with a circular inner cavity in the middle, a handle at the lower end of the sleeve, an upright post at the upper end of the sleeve, and a guide rod which is fixed on the upright post by a screw and can move right and left. The horizontal end of the guide rod is provided with a depth scale, and the other end is provided with a guiding head. The guiding head and the cavity center of the sleeve are in the same line, and the guiding head has a disk shape with depressed center. The utility model can accurately grasp the drilling direction and the drilling out hole position, accurately detect the hole depth, and effectively protect the soft tissues such as muscle, blood vessel, nerve, etc.
Description
(1) technical field under
This utility model relates to a kind of medical bone drill guiding depth measurement protector with guiding, depth measurement, protective effect.
(2) background technology
Bone drill is an orthopaedics apparatus commonly used, when boring deep bone with bone drill, need protect drill bit with an apparatus in the position of estimating the deep bone of brill, in case drill bit damages other tissue.Generally protect drill bit with periosteal elevator at present, but do easy damaged surrounding soft tissue and nervus vasculairs like this, simultaneously, the tissue around promptly easily allowing snarls the drill bit soft tissue in easy damaged drill bit exit again.Also need to measure the degree of depth of boring to determine to select suitable screw, the operation more complicated after having bored the hole.But do not have as yet in the market and a kind ofly can measure the apparatus that hole depth can shield again in advance.
(3) summary of the invention
The purpose of this utility model is to provide a kind of medical bone drill guiding depth measurement protector that has guiding, depth measurement, protective effect simultaneously.
The purpose of this utility model is achieved in that
Protector of the present utility model; by the middle part be handle, the sleeve upper end of sleeve, the sleeve lower end of round cavity column, be fixed on the column and guide post that can move left and right is formed by screw; the horizontal ends of guide post has depth scale; the other end has guide head; guide head and telescopic lumen centers point-blank, guide head is the disc of central concave.
During use, protector of the present utility model is stuck on the skeleton that need to bore, the distance of stretching out by guide post can be read drilling depth on the depth scale from the guide post easily.Bone drill is put into telescopic intracavity, can hole.When boring penetrated skeleton, the drill bit of bone drill just in time withstood on the guide head, had finished skeleton boring.This utility model can accurately be held the position that boring direction and drill bit portal; depth scale can move display depth with drill bit; it can before boring the degree of depth of accurately measuring the hole; reach the soft tissue that drill bit portals and locates around can effectively protecting simultaneously drill bit, prevent that surrounding tissue is entangled to drill bit and accidentally injures nervus vasculairs.
The beneficial effects of the utility model are, can accurately hold boring direction and the hole site of holing out, accurately measure drilling depth, effectively protect soft tissues such as muscle, blood vessel, nerve.
(4) description of drawings
Accompanying drawing is a structural representation of the present utility model
Among the figure, 1 sleeve, 2 handles, 3 columns, 4 guide heads, 5 depth scales, 6 screws, 7 guide posts
(5) specific embodiment
As shown in the figure, be the structural representation of a kind of specific embodiment of the present utility model.Described protector is mainly by forming with lower member: sleeve 1, handle 2, column 3, guide post 7.The horizontal ends of guide post has depth scale 5, and the other end has guide head 4, and guide head and telescopic lumen centers are point-blank.
Protector of the present utility model, sleeve 1 is a cylindrical shape, the drill bit of inner chamber and bone drill matches, and is used for fixing and locatees the bone drill drill bit, prevents that bone drill from skidding.Column 3 is fixed on the upper end of sleeve 1, and a through hole is arranged at the top of column, and a screw 6 is arranged at through hole top, and guide post inserts in the through hole, and by screw fixed guide pole 7.Unscrew screw 6, can make guide post 7 move left and right.Have depth scale 5 on the guide post 7, be used to indicate drilling depth, there is a guide head 4 end of guide post 7 simultaneously, the lumen centers of guide head 4 and sleeve 1 point-blank, guide head is the disc of central concave, after bone drill bored deep head, drill bit just in time pushed up in the guide head in the heart, prevented the soft tissue around the drill bit injury.
Claims (1)
