Abstract
The utility model discloses a bone drill external member is used in operation, including the bone drill, the guiding mechanism who is used for fixing a position the boring direction that the activity was cup jointed at the bone drill front end, guiding mechanism rotationally installs the positioning seat on fixing base upper portion including the pipy fixing base of a transparent plastic material's circle to and decide in a fastening that is used for of fixing base lateral wall through threaded connection the locking screw of positioning seat, the positioning seat lateral wall is spherical surface, in the fixing base upper portion week be with the spherical wall of positioning seat lateral wall matched with. The positioning seat can rotate by the relatively fixed seat to the adjustment angle of punching can be punched on inserting the positioning seat with the bone drill front end. Because the shape of every bone is different, support the length that the screw stretches out through the adjustment, can make the fixing base lower extreme stabilize and place on bone. Locking screw is locking after the positioning seat is adjusted to the right place, makes positioning seat and fixing base relatively fixed.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of bone drill external member structure being beneficial to the accurately punching on bone when synthetism.
Background technology
In current fracture reduction operation, general use blade plate attachment screw is locked at knochenbruch both sides and plays positioning supports effect, is removed by blade plate after bone heals again.Need the relevant position first on bone to punch so that the connection of screw when installing blade plate, when punching, general direct bone hand drill carries out punch operation at present, because bone shaped is different, the bad grasp of position angle of punch operation hole when, punching produces the installation that the words offset are unfavorable for blade plate, is also unfavorable for the healing of bone breaking part.
Summary of the invention
Technical problem to be solved in the utility model is: the deficiency existed for prior art, provides a kind of simple and ingenious structure, the bone drill external member that can easily and accurately hole on bone.
For realizing the object of this utility model, be achieved by the following technical solutions: a kind of operation bone drill external member, includes bone drill, be actively socketed on the guiding mechanism in order to location drilling direction of bone drill front end; Described guiding mechanism includes the holder of the circular tube shaped of a transparent plastics material, is installed in rotation on the positioning seat on holder top, and is threaded connection the lock-screw in order to hold out against fixing described positioning seat at holder sidewall; Described positioning seat sidewall is spherical surface, and holder top inner circumferential is the spherical wall matched with described positioning seat sidewall.
As preferably: described holder is threaded connection 3-6 the supporting screw along holder axis.
As preferably: described lock-screw runs through the sidewall of described holder, and the afterbody of lock-screw is connected with the swing handle of U-shaped.
As preferably: described supporting screw runs through described holder two ends, and the afterbody of supporting screw is connected with the swing handle of U-shaped.
As preferably: described positioning seat intermediary form has the through hole passed for bone drill bit, positioning seat is positioned at and is fixedly connected with a soft rubber sleeve above through hole, rubber sleeve mates with bone drill front end and is socketed.
As preferably: described rubber sleeve inwall is horn mouth shape wide at the top and narrow at the bottom.
Compared with prior art, the beneficial effects of the utility model are: described positioning seat can rotate relative to holder, to adjust the angle of punching, is inserted into bone drill front end on positioning seat and can punches.Because the shape of every block bone is different, the length of being stretched out by adjustment supporting screw, can make holder lower end firmly be placed on bone.Described lock-screw is locked after positioning seat is adjusted to the right place, makes positioning seat relative with holder fixing.

Detailed description of the invention
With reference to the accompanying drawings detailed description of the invention of the present utility model is made a detailed explanation below.
According to Fig. 1 and Fig. 2, bone drill external member is used in the one operation described in the present embodiment, includes bone drill 1, is actively socketed on the guiding mechanism in order to location drilling direction of bone drill front end; Described guiding mechanism includes the holder 2 of the circular tube shaped of a transparent plastics material, is installed in rotation on the positioning seat 3 on holder top, and is threaded connection the lock-screw 5 in order to hold out against fixing described positioning seat at holder sidewall; Described positioning seat sidewall is spherical surface, and holder top inner circumferential is the spherical wall matched with described positioning seat sidewall.
Described holder is threaded connection 3-6 the supporting screw 4 along holder axis.
Described lock-screw runs through the sidewall of described holder, and the afterbody of lock-screw is connected with the swing handle of U-shaped.
Described supporting screw runs through described holder two ends, and the afterbody of supporting screw is connected with the swing handle of U-shaped.
Described positioning seat intermediary form has the through hole passed for bone drill bit, positioning seat is positioned at and is fixedly connected with a soft rubber sleeve 31 above through hole, and rubber sleeve mates with bone drill front end and is socketed.
Described rubber sleeve inwall is horn mouth shape wide at the top and narrow at the bottom.
Described positioning seat can rotate relative to holder, to adjust the angle of punching, is inserted into bone drill front end on positioning seat and can punches.Because the shape of every block bone is different, the length of being stretched out by adjustment supporting screw, can make holder lower end firmly be placed on bone.Described lock-screw is locked after positioning seat is adjusted to the right place, makes positioning seat relative with holder fixing.
