Embodiment Construction

[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be described in detail below in conjunction with the embodiments and accompanying drawings.

[0020]

[0021] figure 1 It is a schematic diagram of the structure of the nerve tension detector in the embodiment of the present invention.

[0022] Such as figure 1 As shown, a nerve tension detector 100 provided in this embodiment includes: a bracket 10, a load cell 20, a fixed rod 30, a movable rod 40, a reel 50, a motor (not shown in the figure), a switch member 60, Display screen 70 , housing 80 and spring 90 .

[0023] The bracket 10 is in the shape of a cuboid and is used to carry the load cell 20 , the fixed rod 30 , the movable rod 40 and the reel 50 , and at the same time provide a fulcrum for the movable rod 40 to measure force.

[0024] The load cell 20 includes a load cell main body 21 and a load cell wir...

Abstract

The invention provides a nerve tension detector, and belongs to the field of medical instruments. The nerve tension detector comprises a support, a force measuring sensor, a force measuring part, a driving assembly, a switch part and a display screen, wherein the force measuring sensor is installed on the support and used for measuring the tension of nerves; the force measuring part is installed on the force measuring sensor and used for pulling the nerves; the driving assembly is used for driving the force measuring part to pull the nerves; the switch part is used for controlling the drivingpart to be turned on or turned off; and the display screen is in communication connection with the force measuring sensor and used for displaying the tension of the nerves. The nerve tension detectorcan detect the tension of the nerves of a patient at any time when a lumbar surgery is conducted, and the display screen can display the measured tension value in real time, so that real-time data reference is provided for smooth conduction of the surgery.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a nerve tension detector. Background technique [0002] Lumbar disc herniation is a common spinal degenerative disease, which is more common in middle-aged and elderly people. Both minimally invasive surgery and traditional surgery have surgical risks, especially concurrent foot drop, which will seriously affect the patient's limb function and quality of life. The main cause of foot drop is weakness of the anterior calf muscle group, which is innervated by the common peroneal nerve. According to relevant research, greater nerve root tension is one of the risk factors for foot drop after lumbar disc herniation surgery. [0003] However, there is no device capable of measuring nerve tension during lumbar disc herniation surgery in the prior art, so the nerve tension cannot be well controlled within an appropriate range. Contents of the invention [0004] The present invention i...
