Detailed Description
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
A pair of laparoscope measuring forceps is shown in figures 1 and 2 and comprises a forceps body 1, wherein the forceps body 1 is also provided with a handle and a forceps head, the forceps head also comprises a main forceps head and an auxiliary forceps head,
the junction of main binding clip and pincers body 1 rotationally articulates there is driving gear 2, the handle rotationally articulates with the link of pincers body 1 has driven gear 3, driving gear 2 and driven gear 3 all interlock each other with main conveyer belt 21, main connecting rod 22 has still been installed to driving gear 2, the one end of main connecting rod 22 and the center fixed connection of driving gear 2, the other end of main connecting rod 22 and one side fixed connection that is close to driving gear 2 of main binding clip, driven gear 3's surface still fixedly connected with principal and subordinate moves pole 32, driven gear 3's inboard has still fixed dipperstick 31 of having installed, dipperstick 31 and driven gear 3's centre of a circle fixed connection.
Further, the counter driving gear 4 has still been installed to the opposite face of driving gear 2, counter driving gear 4 rotationally articulates in the junction of vice binding clip and pincers body 1, the opposite face of driven gear 3 rotationally articulates there is vice driven gear 6, vice driving gear 4 and vice driven gear 6 all interlock with vice conveyer belt 5 each other, vice connecting rod 41 has still been installed to vice driving gear 4, the one end of vice connecting rod 41 and the central fixed connection of vice driving gear 4, the other end of vice connecting rod 41 and the vice pincers head rest are close to one side fixed connection of vice driving gear 4, the surface of vice driven gear 6 still fixedly connected with vice driven rod 61, vice dipperstick 62 has still been fixedly installed to the inboard of vice driven gear 6, vice dipperstick 62 and the centre of a circle fixed connection of vice driven gear 6.
