Abstract
The utility model discloses a cardiovascular internal diameter measuring instrument which comprises a support rod. One end or two ends of the support rod are respectively provided with a hinged plate with a ring protuberance, and connecting rods which are connected with the hinged plate in hinged mode are alternately distributed on the hinged plate. Cylindrical measuring heads which are all different in diameter are arranged on the ends of the connecting rods. The support rod, the hinged plate, the connecting rods and the measuring heads are all made of medical plastic or stainless steel. The cardiovascular internal diameter measuring instrument has the advantages of being simple in structure, convenient to use, suitable for patients of different ages, and capable of improving operation effect. Moreover, the cardiovascular internal diameter measuring instrument has little measuring error because the measuring heads with different diameters are arranged and can respectively measure or expand different-thickness inner diameters of heart vessels.
Description
Technical field:
This utility model relates to survey tool, particularly a kind of cardiovascular inside caliper.
Background technology:
At present, usually need expand, measure the cardiovascular internal diameter in the operation on vessels of heart clinically, measure accurately convenient and practical survey tool but lack always, have many surgeons to utilize the general appraisal of finger, measurement error be bigger, can influence surgical effect.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming that exists in the prior art, and a kind of simple in structure, easy to use and cardiovascular inside caliper that measurement error is little is provided.
To achieve these goals; This utility model provides a kind of cardiovascular inside caliper; Comprise support bar; The one or both ends of said support bar are provided with the articulated slab of circular protrusion, alternately are distributed with the connecting rod that is articulated and connected with said articulated slab on the said articulated slab, and it is all inequality that the end of said connecting rod is provided with the diameter of cylindrical gage outfit and each gage outfit.
Said support bar, said articulated slab, said connecting rod and said gage outfit are processed by medical plastic or rustless steel.
The outstanding advantage of this utility model is: simple in structure, easy to use, owing to be provided with the gage outfit of a plurality of different-diameters, can measure or expand the cardiovascular internal diameter of different thicknesses respectively, and measurement error is little, is fit to the patient at various ages, to improve operative effect.
Description of drawings:
Fig. 1 is the overall structure front view of this utility model embodiment.
Fig. 2 is the upward view of Fig. 1.
The specific embodiment:
Design agents mechanism comprised support bar 1, articulated slab 2, connecting rod 3 and gage outfit 4 when the embodiment of this utility model implemented.Wherein, the two ends of support bar 1 are provided with the articulated slab 2 of circular protrusion, alternately are distributed with four connecting rods 3 that are articulated and connected with articulated slab 2 on the articulated slab 2, and it is all inequality that the end of connecting rod 3 is provided with the diameter of cylindrical gage outfit 4 and each gage outfit 4.Support bar 1, articulated slab 2, connecting rod 3 and gage outfit 4 are processed by medical plastic.
The diameter of each gage outfit 4 is all inequality, simultaneously in each its diameters of gage outfit 4 marked, can make things convenient for, get information about the concrete diameters of each gage outfit 4.
