Abstract

The utility model discloses an orientator for drilling holes on bones, belonging to a medical device. The utility model solves the disadvantages existing in an existing publicly known orientator for drilling holes that fixation is difficult, and range of use is narrow. The utility model is composed of a horizontal orientation rod, a perpendicular orientation rod, an inserting needle base, a handle and a fastening screw. The utility model adopting the structure can slide from top to bottom to be adjusted according to the thickness of an affected limb. A rod tip of the perpendicular orientation rod and inner holes of the inserting needle base are horizontally perpendicular all the time, which can ensure that a needle can be accurately inserted and withdrawn. Models of the inner holes of the inserting needle base are different, which leads the utility model to be suitable for Kirschner needles with different thickness. The handle is provided with such an angle that the handle is convenient to be held, which is good for the clinical usage of the utility model.

Description

A kind of orthopaedics boring finder

The utility model discloses a kind of orthopaedics boring finder, belong to medical apparatus and instruments.

At present, known orthopaedics boring finder is made up of inserting needle base and handle, and its deficiency is in use to be difficult to fix, and the boring aperture that the inserting needle base is provided with is single, can not satisfy actual needs.

The purpose of this utility model is to develop a kind of orthopaedics boring finder clinical, simple in structure, easy to use that is applicable to.

The purpose of this utility model is achieved in that orthopaedics boring finder partly is made up of horizontal orientation bar, vertical orientation bar, inserting needle base, handle and trip bolt five; Wherein the section of horizontal orientation bar is rectangular solid, and an end is provided with a round platform with holes, and the other end offers a rectangular hole, and the right side of slot offers a screw; The vertical orientation bar is positioned at the slot of horizontal orientation bar one end, and section is foursquare solid, and shaft is an angle of 90 degrees bending, and the bar point is acute angle, be positioned at horizontal orientation bar round platform hole directly over; The inserting needle base is the pipe that a head has boss, and its endoporus is processed into corresponding model according to the thickness of Kirschner wire; The section of handle is circular, is connected in an end of horizontal orientation bar round platform, with horizontal vertical bar shape declivity in obtuse angle; The quantity of trip bolt is 1, is installed in the screw on horizontal orientation bar slot right side.

Adopted the utility model of said structure, the trip bolt by being provided with on the horizontal orientation bar between horizontal orientation bar and the vertical orientation bar can slide up and down in the rectangular hole on the horizontal orientation bar according to the thickness of suffering from limb and regulate; Since the bar point of vertical orientation bar be positioned at horizontal orientation bar round platform directly over, thereby the endoporus of the bar point that makes the vertical orientation bar and inserting needle base horizontal vertical has all the time been guaranteed inserting needle and has been gone out the accuracy of pin; The endoporus of the model that the inserting needle base is different makes this utility model be applicable to the Kirschner wire that thickness is different; The angle of handle setting is convenient to control, and helps clinical use of the present utility model.

Below in conjunction with accompanying drawing this utility model is described further.

Fig. 1 is a front view of the present utility model;

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is a side view of the present utility model.

Referring to accompanying drawing, this utility model partly is made up of horizontal orientation bar 1, vertical orientation bar 2, inserting needle base 3, handle 4 and trip bolt 5 five; Wherein the section of horizontal orientation bar 1 is rectangular solid, and an end is provided with one with holes 6 round platform 7, and the other end offers a rectangular hole 8, and the right side of slot 8 is provided with a screw 9; Vertical orientation bar 2 is positioned at the slot 8 of horizontal orientation bar 1 one ends, and section is foursquare solid, and shaft is an angle of 90 degrees bending, and bar point 10 is acute angle, be positioned at round platform 7 holes 6 directly over; Inserting needle base 3 is the pipe that a head has boss, and the endoporus 11 of pipe is processed into corresponding model according to the thickness of Kirschner wire; The section of handle 4 is circular, is connected in an end of horizontal orientation bar 1 round platform 7, with horizontal vertical bar 1 shape declivity in obtuse angle; The quantity of trip bolt 5 is 1, is installed in the screw 9 on horizontal orientation bar 1 slot 8 right sides.

During use,, vertical rod 2 is pulled out suitable length, the trouble limb is put into space between horizontal orientation bar 1 and the vertical orientation bar 2 according to the thickness of suffering from limb; Make the bar point 10 of vertical orientation bar 2 be positioned at the pin mark that of Kirschner wire, after the endoporus 11 of inserting needle base 3 aimed at the entry point of Kirschner wires, tighten trip bolt 5, hold handle 4 keeping the stable of finder, Kirschner wire is pierced from the endoporus 11 of inserting needle base 3 suffer from limb and can finish directional drilling.
