[0002] Physical examination refers to the most basic examination method in which doctors use their senses and examination tools to understand and evaluate the condition of the human body. In actual hand surgery diagnosis and treatment examination work, it is necessary to test the patient's arm. In the examination after some musculocutaneous nerve injuries, it is necessary to test the patient's biceps. Usually, the doctor's thumb accurately presses the tendon in the antecubital fossa of the biceps, and the percussion hammer taps the thumb position to stimulate the biceps tendon to observe whether the patient's arm flexes due to muscle contraction after tendon tapping. The current hand surgery arm physical examination test equipment is not convenient for automatic positioning of the biceps tendon, and the error rate of manual positioning and pressing is high, which can easily cause reflex elicitation failure. At the same time, it is not convenient for automatic power storage tapping. Doctors perform tapping operations for a long time, and long-term tapping of the thumb will cause injury and pain.

[0039] Embodiment 2, on the basis of embodiment 1, the reaction detection member 7 comprises: a detection sliding block 701 and a displacement sensor 702, which can be a HZC-H1 type displacement sensor 702, and a matching display 104 is used, the detection sliding block 701 is slidably mounted on the detection mounting shell 1031; the displacement sensor 702 is fixedly mounted on the bottom of the detection sliding block 701; the displacement sensor 702 is attached to the inner side of the detection mounting shell 1031; the displacement sensor 702 is used to detect the flexion of the lower arm; the reaction detection member 7 also comprises: a support spring 703 and a support pad 704, two support springs 703 are fixedly mounted on the bottom of the detection sliding block 701, and the ends of the two support springs 703 are respectively fixedly mounted inside the detection mounting shell 1031; the top of the detection sliding block 701 is fixedly mounted with a support spring 703 and a support pad 704. A support pad 704 is fixedly installed on the part; a rubber coating is provided on the outer side of the support pad 704; the displacement sensor 702 is electrically connected to the display 104, and the reaction detection component 7 is used, so that the doctor can understand the degree of flexion of the forearm more intuitively, and the detection of the flexion reaction of the forearm is more accurate, which can improve the detection quality of the biceps reflex of the present structure, and small changes can be detected to prevent missed detection. At the same time, the reflex degree can be understood more intuitively, and the display 104 can be used to quickly observe and know that the forearm will be affected by the contraction of the biceps brachii and cause flexion. The force acting on the detection sliding block 701 is reduced, and the pressure data is displayed through the display 104. If the patient's forearm does not show a flexion reaction, it means that the patient's biceps reflex has a problem, and subsequent diagnosis and treatment can be carried out in time.

[0040] The working principle of this embodiment is as follows: first, place this structure beside the bed. When the inflation airbag 401 is under normal pressure, rotate and adjust the threaded rod 602 to drive the pressure regulating piston disc 603 to move upward inside the piston cylinder 601, so as to control the suction of the inflation airbag 401. The inflation airbag 401 can shrink and adjust to fit the patient's upper arm. The patient lies flat, and the upper arm passes through the mounting cylinder 101 and is placed on the supporting pad 102. At this time, the patient's biceps brachii exerts force to bend the forearm. At this time, the biceps brachii tendon bulges. The groove of the tendon adapter groove 3011 is used to be stuck in the tendon adapter groove 3011, and the tendon positioning spring 302 is pulled to ensure the fit. At this time, the rotating adapter ring 201 can be rotated, and the adapter slider 301 is buckled on the tendon protrusion. At this time, the positioning bolt 105 can be tightened to squeeze the fitting positioning plate 202, and the rotating adapter ring 201 is positioned, that is, the position of the positioning adapter slider 301 is positioned, and the patient can relax his forearm; when the patient bends his arm to position the tendon, the biceps brachii When the biceps brachii muscle bulges, the inflatable airbag 401 can be squeezed, and the internal gas of the inflatable airbag 401 is squeezed into the air pressure sliding cylinder 402. The air pressure controls the telescopic sliding cylinder 403 to rise, which can squeeze the limit plate 504 and push the sliding column 501 to rise. During the process, the positioning spring 305 squeezes the one-way positioning block 303 and inserts the thorn-shaped teeth on the sliding column 501 in real time. The thorn-shaped structure is used for automatic positioning. When the patient completes the positioning of the tendon and relaxes the forearm, the inflatable airbag 401 is no longer squeezed, and the telescopic sliding cylinder 403 is pulled down and reset with the air pressure reset spring 404 to avoid affecting the subsequent downward movement of the sliding column 501 to knock the tendon; the sliding column 501 can also be directly pulled up manually to store force; when performing reflex detection, the positioning shaft 304 is manually pulled to drive the one-way positioning block 303 to separate from the sliding column 501 to realize the limit release. Under the pull of the knocking spring 503, the sliding column 501 drives the knocking rubber head 502 to move down quickly to knock the biceps brachii tendon;

[0041] The patient's forearm is relaxed and placed on the support pad 704. When the knocking rubber head 502 moves down to knock the biceps tendon, the forearm will be affected by the contraction of the biceps and cause flexion. At this time, the elastic support of the support spring 703 is used. The forearm is affected by the muscle contraction and flexion occurs. The force acting on the detection sliding block 701 is reduced, and the displacement sensor 702 can detect the reduction in pressure. The pressure data is displayed on the display 104, and the doctor can observe this data.
