Description

Strabismus forceps for quantitatively measuring extraocular muscle strength

Technical Field

The invention relates to the technical field of strabismus treatment instruments, in particular to strabismus forceps for quantitatively measuring extraocular muscle strength.

Background

As social development and economic levels increase, the traditional biomedical model is micro, and the bio-psycho-socio-medical model is generated and strong. In this model, the patient's treatment of the disease is influenced by the disease itself and by "psychological", "social" factors from the patient; it is the highest goal for medical personnel to reduce "trauma" or to make "no trauma" measurements as much as possible during the measurement process, and to make accurate quantitative measurements and easy readings.

At present, eye movement examination, traction test and the like are modes for indirectly evaluating the function of extraocular muscles, the experience and judgment of an examiner are emphasized, and the examination result is easily interfered by the outside; the eye movement examination is a non-quantitative and non-direct method for examining the function of the extraocular muscles, and the extraocular muscle function can be indirectly judged by examining the amplitude of the eye movement. However, the examination is difficult to quantify accurately, is greatly influenced by the attention and cooperation of patients, and has poor repeatability among different examiners. The traction test is also a method for evaluating the function of the extraocular muscles, which is commonly used in clinical practice, and the muscle strength and the tension of the extraocular muscles are judged by the examiner's perception of the strength of traction in the active traction test and the passive traction test, respectively, but the examination is non-quantitative. The above methods for examining the function of extraocular muscles are very dependent on the experience and judgment of examiners, and the consistency among examiners is poor.

In the past, a pulley and an elastometer are connected and disconnected extraocular muscles in an operation to directly measure the extraocular muscle strength, but the method can only be applied in the operation and is inconvenient for routine clinical examination. The muscle strength of the extraocular muscles is measured by clamping the corneal limbus by a forceps-connected transducer, but the operation is not easy and the extraocular muscles are not used clinically. The existing 201710025506.1 patent has the defects of low detection precision and inconvenient disinfection treatment by a common clinical method due to the integration of electronic components.
