Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a thrombus biopsy forceps of adjustable crooked, including handle 1, a serial communication port, pull ring 11 is installed to the one end of handle 1, fluting 12 has been seted up at the middle part of handle 1, the outside cover of handle 1 is equipped with lantern ring 13, the pot head of handle 1 is equipped with controller 14, the outside of controller 14 is provided with software pipe 15, the inside of software pipe 15 is provided with first seal wire 16, second seal wire and third seal wire, first seal wire 16, fixed installation head 17 is run through to second seal wire and third seal wire one end, be provided with elasticity biax dwang 18 in the top of fixed installation head 17, the both sides on fixed installation head 17 top are provided with reset spring 181, the top and the 19 bottom fixed connection in end of elasticity biax dwang 18 and two reset spring 181, second seal wire and third seal wire one end respectively with the both sides fixed connection of end 19.
