Problems solved by technology

[0002] At present, most of the methods for measuring the diameter of the human lumen (or opening distance, because some lumen sections are not circular, but most of them are circular, and the term diameter will be used below to represent them) mostly rely on imaging technology to estimate and calculate the value. However, the image has a ratio, and the developing ability of different tissues is not the same, and the image is usually obtained from one direction or two directions. Bring errors to the final result, time-consuming, "eating rays", the key is not accurate

Embodiment Construction

[0017] Such as figure 2 It can be seen that the six measuring wires (1-2) are respectively connected to the guide head (1-1), and then the other ends of several measuring wires (1-2) are respectively connected to the connector (1-4).

[0018] according to figure 1 , put the annular finger ring (2-6) on the long mandrel (2-3) and put it in place, put the circular sliding block (2-4) on the long mandrel (2-3), and put the metal spiral Install the pipe (2-2) on the long core rod (2-3), pass the steel cable (2-1) through the inner cavity of the metal spiral hose (2-2), and connect the The steel cable (2-1) is connected to the circular sliding block (2-4), and the assembly of the operating handle part (2) is completed.

[0019] according to figure 1 , move the circular sliding block (2-4) to the dead point in the direction of the measuring head part (1), pass the free end of the steel cable (2-1) through the connector (1-4) of the part (1), Let the free end of the steel cable ...

Abstract

The invention discloses a measuring scale, and relates to the technical field of medical instruments, the measuring scale comprises an operating handle part and a head measuring part, the head measuring part is composed of a measuring wire, a guide head, a connector and a stop ring, and the operating handle part is composed of an annular finger ring, a long core rod, a circular sliding block, a metal spiral hose, a fixing clamp and a steel cable. The free end of the steel cable penetrates through the connector and the stop ring of the head measuring part, the stop ring is fixed at a set position, the free end of the steel cable penetrates through the guide head and is connected with the steel cable and the guide head, the free end of the metal spiral hose is connected with a tail hole of the connector, and the measuring wire is made of hyperelastic materials. The measuring scale is used in cooperation with an endoscope, the diameter of a channel of a treatment instrument of the endoscope is usually about 3 mm, under the small condition, design of moving parts is reliable, and the measuring scale is convenient and rapid and cannot injure a patient accidentally.

Description

technical field [0001] The invention relates to the field of endoscopic medical instruments, in particular to a measuring ruler. Background technique [0002] At present, most of the methods for measuring the diameter of the human lumen (or opening distance, because some lumen sections are not circular, but most of them are circular, and the term diameter will be used below to represent them) mostly rely on imaging technology to estimate and calculate the value. However, the image has a ratio, and the developing ability of different tissues is not the same, and the image is usually obtained from one direction or two directions. Bring errors to the final result, time-consuming, "eating rays", the key is not accurate. [0003] Endoscopes have been widely used in the examinations of digestive tract, respiratory, urological and other departments. If a device can be used to check the diameter of the human cavity through the endoscope, it can be measured under the direct vision ...
