Its treatment scope mainly covers trauma, diseases, congenital or acquired defects and deformities of tissues or organs such as skin, muscles and bones. Before plastic surgery on human skin, it is necessary to measure the skin first, so that medical staff can make accurate surgical plans. However, since the human epidermis is not flat, the measurement accuracy of the skin is insufficient, which affects the recovery of the skin after surgery. Utility Model Content

The measuring wheel 2 is rotatably arranged on one side of the support frame 1. Figure 2 As shown, the measuring wheel 2 rotates on the skin, and the measuring mechanism 3 is installed on the support frame 1 and is transmission-connected with the measuring wheel 2. The measuring mechanism 3 measures the number of rotations of the measuring wheel 2, thereby calculating the distance moved by the measuring wheel 2, so as to measure the skin. The unfolding mechanism 4 is arranged on the support frame 1, and the skin is unfolded by the arranged unfolding mechanism 4, thereby preventing skin wrinkles from affecting the measurement accuracy.

[0027] It can be imagined that in this solution, the skin is measured by the number of rotations of the measuring wheel 2.

[0030] Optionally, a first transmission belt 44 is provided between the transmission member 411 and the measuring wheel 2 to achieve unidirectional power transmission through the transmission belt. On this basis, chain transmission and power transmission using multiple gear structures can also be selected.

[0031] Optionally, the unfolding arm 42 is hingedly set on the support frame 1, and a torsion spring is provided at the hinge position of the unfolding arm 42 and the support frame 1. The torsion spring can apply a bending force to the unfolding arm 42, so that the unfolding arm 42 can press the unfolding wheel 43 toward the human skin, thereby improving the unfolding efficiency of the unfolding mechanism 4.

[0032] Preferably, a marker pen 5 is provided on one side of the support frame 1 near the measuring wheel 2, and the marker pen 5 is slidably set on the support frame 1. A pressure spring is provided on the marker pen 5, and the pressure spring presses the marker pen 5 to the outside of the support frame 1. The marker pen 5 can slide out a mark on the area passed by the measuring device, thereby facilitating medical staff to judge and correct the measuring area, and the marker pen 5 is pushed toward the skin by the pressure spring, thereby keeping the marking of the marker pen 5 even.

[0033] Preferably, the measuring mechanism 3 includes a metering wheel 31 and a metering device 32, a plurality of feedback members 33 are arranged at equal intervals around the circumference of the metering wheel 31, the metering wheel 31 is rotatably arranged in the support frame 1, the metering wheel 31 is transmission-connected to the measuring wheel 2, the metering device 32 is arranged in the support frame 1, the metering device 32 counts the feedback members 33 on the metering wheel 31, a pulley 6 is arranged on the measuring wheel 2, a second transmission belt 34 is sleeved on the pulley 6 and the metering wheel 31, when in use, the measuring wheel 2 contacts the skin, the measuring wheel 2 is used to record the length of the skin passing through the part, the measuring wheel 2 drives the second transmission belt 34, and the metering wheel 31 is driven by the second transmission belt 34, at this time, the plurality of feedback members 33 on the metering wheel 31 rotate synchronously, and the number of the feedback members 33 is counted by the metering device 32, each passing of a feedback member 33 represents a unit length moved by the measuring wheel 2 on the skin, so that the skin can be measured in real time.

During operation, the metering wheel 31 drives the feedback members 33 to rotate one by one to the laser transmitter, and a laser signal is generated by the laser transmitter. When the laser signal is transmitted to the feedback member 33, it is reflected and transmitted to the laser receiver.
