Technical field
The utility model is related to the field of medical instrument technology, specifically a kind of to be connect with bone external fixing rack for half needle
Bindiny mechanism.
Background technology
Half needle is widely used in the fixation of bone in surgical operation, and now fixed half needle is generally logical outside Orthopedic medical in the art
It crosses the fixing nut that common folder needle connecting pole coordinates its bottom end to connect to be fixed, is primarily present following problem：(1) weight
Greatly, in surgical operation, outer fixed ring, half needle is generally comprised for fix bone fixing device and half needle is fixed on outer fixation
Connector on ring, the material prepared have been substantially made of stainless steel, there is a problem of that volume and weight is big, Huan Zhechang
Time is using having aggravated the burden of patient and extended the recovery from illness of wound；(2) folder needle connecting pole can only come according to its axis direction
Angle appropriate is adjusted, then fixing nut is locked to the fixation for carrying out half pin position, what is adjusted the angle is limited in scope, and removes axis
The angle in other directions can not be adjusted outside direction, and selectivity is smaller；(3) half needles need by press from both sides needle connecting pole on through-hole come
It threads a needle, and the direction threaded a needle and angle can not also be adjusted, and be also restricted during use, if first threaded a needle, then be led to
The fixation of folder needle connecting pole is crossed, often because leading to not alignment lead to the hole site due to failure, therefore the folder needle connecting pole is clinically
Application limitation it is larger.Patent No. 2015200137080 discloses a kind of structure-improved of half needle rotation fixture block, the structure
For the fixation of outer fixed ring and half needle, but still that there are weight is big, complicated, and can only fix one and half needle uses and compare
Limitation adjusts inconvenient problem.
Utility model content
The purpose of this utility model is to provide one kind for half needle and bone external fixing rack the problem of presence in view of the above technology
The bindiny mechanism of connection, the fixture have small, and weight is small, it can be achieved that the characteristics of half needle multi-angle regulation.
To achieve the above object, the technical solution adopted in the utility model is：One kind connects for half needle and bone external fixing rack
The bindiny mechanism connect, including threaded rod, on the threaded rod be equipped at least two groups fixture, one of which fixture be used for it is outer solid
The cross bar for determining frame is fixed, and another group of fixture is for fixing half needle, and fixture described in every group is including a fixture block, a briquetting and for fixing
The nut of fixture block or fixture block is equipped with the arc groove for clamping cross bar or half needle, described in the front end of the fixture block or briquetting
It is equipped with buffer layer in arc groove, is equipped with a raised line in the rear end of the fixture block, is equipped in the briquetting rear end corresponding with raised line
Groove.
Further, wherein the angle of the arc groove and threaded rod for fixing on fixture described in one group of half needle is 70-
90 degree, be 90 degree for the fixture of fixture and threaded rod described in another group of fixed transverse rod.
Further, the threaded rod is M6 threaded rods or M8 threaded rods.
Further, the threaded rod is hollow metal structure.
Further, the buffer layer is elastic rubber.
The advantageous effects of the utility model are：The utility model can fast implement consolidating between half needle and outer fixed ring
It is fixed, due to two groups of fixtures can threaded rod move horizontally, while can also threaded rod be that 360 degree of shaft rotates, be fixed
When can realize that horizontal bidirectional and 360 degree of universal multi-axis are fixed, meet the fixed of different angle in surgical operation and require, and this reality
With the novel fixture quantity that can arbitrarily add to meet the fixation of more half needles, the utility model connecting-piece structure is very simple,
Small volume, weight is also very light, can effectively reduce the weight of entire external fixation device, and patient wears more comfortable, promotion patient
Rehabilitation.
