At this time, the distance between the movable sleeve 104 and the fixed sleeve 103 changes, and the cutting knife 105 is tilted, so that the cutting knife 105 can cut the changed width of the fascia lata, which is convenient for obtaining fascia lata of different widths. It can be understood that the above-mentioned scheme can be used to facilitate the acquisition of fascia lata of different widths, and can also be used to solve the problem of cutting fascia lata.

[0033] According to the present specific embodiment, the fixed sleeve 103 is fixedly connected to the mounting seat 101 and is located at one side of the mounting seat 101. The driving member 107 is arranged on the mounting seat 101. The movable sleeve 104 is connected to the mounting seat 101 through the driving member 107.

[0037] In addition, the limit block 115 is fixedly connected to the sliding seat 113 and is located on one side of the sliding seat 113; the moving sleeve 104 has a limit groove 117, and the limit groove 117 is arranged on the moving sleeve 104 and is located on the side of the moving sleeve 104 close to the limit block 115, and the limit groove 117 cooperates with the limit block 115; the limit groove 117 and the limit block 115 are each provided with two, and are respectively located on the upper and lower sides of the sliding seat 113, and the limit block 115 is limited by the limit groove 117, and then the sliding seat 113 is limited, so that the sliding seat 113 can only move along the length direction of the limit groove 117, while preventing the sliding seat 113 from being separated from the moving sleeve 104, affecting the cutting of the broad fascia.

[0038] Finally, the chamfer 118 is disposed on the blade 114 and is located on the side of the blade 114 away from the mounting seat 101; the chamfer 118 is located on the side of the blade 114 away from the cutting edge, thus preventing the blade 114 from cutting other tissues during the insertion process.

[0039] When using the precise acquisition device of the fascia lata of the present embodiment, an incision is made on the outside of the patient's thigh, and the device is inserted. The insertion length is judged by the scale line 109. When the insertion length is consistent with the length of the fascia lata to be acquired, the insertion is stopped. At this time, the mounting seat 101 is pulled outward, thereby driving the fixed sleeve 103, the movable sleeve 104 and the cutting knife 105 to move outward. At this time, the blade of the cutting knife 105 can cut the fascia lata, and finally the fascia lata is cut by the cutting member 108, that is, the acquisition of the fascia lata is completed; when it is necessary to acquire fascia lata of different widths, the movable sleeve 104 is driven to move by the driving member 107, thereby adjusting the distance between the movable sleeve 104 and the fixed sleeve 103.
