A kind of articulations digitorum manus connectorTechnical field
The present invention relates to the technical field protected after finger-joint fracture, particularly a kind of articulations digitorum manus connector.
Background technology
In punch process workshop, workman's maloperation often occurs, causes finger to be broken by drift.After breaking, workmanIt is at a loss, the finger of fracture firm can be embraced with another, crack longitudinally extension can be caused, fracture width change is also resulted inGreatly, great difficulty further is brought to post-operative connection, delays optimal treatment period.In addition, by conveying patientDuring hospital, the finger of fracture is exposed to outside, it is easy to impacted by the external world, and fracture extension expands, and entersOne step brings pain to patient.
The content of the invention
It is an object of the invention to overcome the shortcoming of prior art there is provided a kind of compact conformation, prevent faulted joint longitudinally slidingMove and horizontal expansion, using it is simple, avoid the secondary impaired articulations digitorum manus connector of breaking part.
The purpose of the present invention is achieved through the following technical solutions：A kind of articulations digitorum manus connector, it includes protection sleeve, instituteScrewed hole A is provided with the top of the protection sleeve stated, screwed hole A internal threads are connected with the screw A of vertical setting, and screw A is downwardExtend in protection sleeve, and screw A bottom is provided with foam pad A, the bottom of described protection sleeve is provided with screwed holeB, screwed hole B internal threads are connected with the screw B of vertical setting, and screw B is extended downwardly in protection sleeve, and screw B bottomFoam pad B is provided with, the bottom of foam pad offers arc groove；Described protection sleeve left part is sealed with end cap, end capOn be threaded with screw rod, screw rod is inserted into protection sleeve, and the plastics being connected with screw rod are provided with described protection sleeveArc-shaped curved surface is offered on pad, the right side of plastic mattress.
Described screw A and screw B is symmetrical arranged.
The right part of described protection sleeve is connected with bandage.
A day word is installed on described bandage to buckle.
The present invention has advantages below：Compact conformation of the present invention, prevent faulted joint straight skidding and horizontal expansion, using letterSingly, avoid breaking part secondary impaired.

Fig. 2 is the structural representation of foam pad；
In figure, 1- protection sleeves, 2- screws A, 3- foam pad A, 4- screw B, 5- foam pad B, 6- arc groove, 7- end caps, 8-Screw rod, 9- plastic mattresses, 10- bandages, 11- days word buttons.
Embodiment
The present invention will be further described below in conjunction with the accompanying drawings, and protection scope of the present invention is not limited to as described below：
As shown in figure 1, a kind of articulations digitorum manus connector, it includes protection sleeve 1, and the top of described protection sleeve 1 is provided with spiral shellPit A, screwed hole A internal threads are connected with the screw A2 of vertical setting, and screw A2 is extended downwardly in protection sleeve 1, and screwA2 bottom is provided with foam pad A3, and the bottom of described protection sleeve 1 is provided with screwed hole B, and screwed hole B internal threads are connected withThe screw B4 of vertical setting, screw B4 are extended downwardly in protection sleeve 1, and screw B4 bottom is provided with foam pad B5, bubbleThe bottom of foam pad offers arc groove 6；The described left part of protection sleeve 1 is sealed with end cap 7, end cap 7 and is threaded withScrew rod 8, screw rod 8 is inserted into protection sleeve 1, and the plastic mattress 9 being connected with screw rod 8, plastics are provided with described protection sleeve 1Arc-shaped curved surface is offered on the right side of pad 9.
Described screw A2 and screw B4 is symmetrical arranged.The right part of described protection sleeve 1 is connected with bandage 10.It is describedBandage 10 on a day word be installed buckle 11.
The course of work of the present invention is as follows：When rupture of finger, the right part of finger from protection sleeve 1 is inserted in itIt is interior, screw rod 8 is rotated, makes screw rod 8 promote plastic mattress 9 to move right, circular arc camber is coordinated with finger tip, it is to avoid the crack of breaking partGap increases, and realizes the longitudinal register of finger, then tightens screw A2 and screw B4, two screws are moved towards, so that top6 armfuls of arc groove at the top of breaking part, and 6 armfuls of bottoms in breaking part of arc groove of bottom, two arc grooves 6 are limitedThe straight skidding in crack, it is to avoid the expansion in crack, bandage 10 finally tied up in wrist, realize the fixation of the device, makeA Su is lost with convenient.Therefore,.In addition it is protected the protection of sleeve, it is to avoid second hurt.
