Abstract
The utility model discloses a clamping unit for rod-rod connection, belonging to the technical field of medical apparatuses and instruments. The clamping unit for rod-rod connection is characterized in that: the clamping unit comprises a screw rod, wherein the screw rod is sleeved with a pliers body; the top of the screw rod is equipped with a nut for locked fit; an upper insertion hole for a carbon fiber connecting rod is formed on one side of the pliers body; and a lower through hole for a carbon rod is formed on the lower part of the screw rod. The clamping unit for rod-rod connection is simple and compact in structure; by forming the upper and lower insertion holes for carbon maintenance connecting rods to connect the carbon fiber connecting rods mutually, the clamping unit for rod-rod connection is flexible and convenient in use, and capable of furthest adjusting the direction and the angle freely; the clamping unit for rod-rod connection is suitable for satisfying demands on anatomical reduction and fixation of different fracture sites, and can meet biomechanical demand of bone function reconstruction.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specially the rod rod and connects binding clasp.
Background technology
Connect with an excellent rod connector between each carbon fibre pitman, the carbon fibre pitman is divided into thick carbon fibre pitman and thin carbon fibre pitman.Thickness different-diameter structural carbon cellulose fiber pitman is made up of excellent body and termination, and the termination is fixed on excellent body two ends, can combine adjustable nail rod to connect binding clasp and firmly keep reduction of the fracture position.Existing excellent rod connector binding clasp, it is stationary structure that its carbon fibre pitman connects jack, motility is good inadequately, can not the free adjustment direction, fixing restricted, the clinical scope of application is limitation.
The utility model content
To the problems referred to above that exist in the prior art; The purpose of this utility model is to design the technical scheme that the good rod rod connection binding clasp of a kind of motility is provided; Its entry point can be chosen on the different plane position; Free adjustment direction and angle are applicable to the fixed requirement of different fracture site anatomical reductions to greatest extent, meet the biomechanics requirement of bone reconstruction.
Described rod rod connects binding clasp, it is characterized in that comprising screw rod, and socket is provided with caliper on the screw rod, and its top cooperates through nut check is set, and caliper one side is provided with carbon fibre pitman jack, and the screw rod bottom is provided with down carbon fibre pitman jack.
Described rod rod connects binding clasp, it is characterized in that socket is provided with retaining on the screw rod of caliper below to connect nut, and retaining tape splicing flank of tooth nut upper surface is provided with the concave-convex clutch tooth.
Described rod rod connects binding clasp, it is characterized in that socket is provided with pad on the screw rod between caliper, the nut.
Described rod rod connects binding clasp, it is characterized in that the screw rod bottom sides is along being equipped with chimb.
Described rod rod connects binding clasp, it is characterized in that caliper is the clip shape structure of aluminum, and its folder shape hollow structure constitutes goes up carbon fibre pitman jack.
Described rod rod connects binding clasp, it is characterized in that caliper and screw rod socket are rotatably assorted.
Above-mentioned rod rod connects binding clasp; Simple in structure, compact; Two carbon fibre pitman jacks are used for the connection between the carbon fibre pitman through being provided with up and down, and are flexible and convenient to use, to greatest extent free adjustment direction and angle; Be applicable to the fixed requirement of different fracture site anatomical reductions, meet the biomechanics requirement of bone reconstruction.
