Self-assisted retractor for surgical operation

[0032] Example one.

[0033] Such as Figure 1-9 Shown.

[0034] A self-service surgical retractor, which is mainly composed of a lifting device 9, a retracting device 10, a traction belt 11 (which can be realized by using a textile belt or a plastic woven belt with a width of about 1 cm) and a hook plate 12 composition, such as figure 1 As shown, the take-up device 10 is installed at the upper end of the lifting rod 4 in the lifting device 10. The take-up device 10 is mainly composed of a housing 13, a telescopic take-up shaft 14 and a rocker 15, and a telescopic take-up shaft The main body of the 14 is located in the housing 13. The rocker arm 15 is connected to one end of the telescopic take-up shaft 14 and is located outside the housing 13. The housing 13 is provided with a groove 16 for accommodating the rocker 15 and one end of the traction belt 11 It is connected to the retractable take-up shaft 14, and the other end passes through the belt hole 17 on the housing 13 and is con

[0045] Example two.

[0046] Such as Figure 1-8 , 10 shown.

[0047] The difference between this embodiment and the first embodiment is that the structure of the take-up shaft 14 is as follows: Picture 10 As shown, the take-up shaft is a fixed-length structure, and its two ends are supported on the shell wall of the housing 13, and one end extends out of the housing 13 to facilitate the sleeve of the shaker 15, and the extension length should be the same as that of the shaker 15. The length of the sleeve on the take-up shaft 14 matches. In this embodiment, the rocking wall 15 and the take-up shaft 14 are in a movable connection structure. When in use, the rocker 15 is put on the take-up shaft 14 on one end of the housing 13 (the two can adopt a polygonal matching structure or a cylindrical hole The matching structure of the pin or key), the position of the groove 16 can be slightly deviated when it is set, so as to avoid the excessive nesting of the rocker. After the rocker 15 is
