Description

Technical Field

[0001] The utility model relates to the technical field of titanium clamp testing, in particular to a titanium clamp body firing test tool. Background Art

[0002] During medical surgery, in order to prevent the target organ from becoming more difficult due to excessive bleeding or ruptured blood vessels, the blood vessels connected to the target organ are usually ligated with titanium nails to stop bleeding. The instrument used is a titanium clamp. The titanium clamp works by first inserting the titanium clamp into the human body, then encircling the blood vessel with the titanium nail, and applying force from the outside to drive the titanium clamp to clamp the titanium nail to achieve the effect of stopping bleeding.

[0003] By holding the firing handle tightly, the push tube axially arranged in the outer tube is driven to move forward and backward, thereby closing the pliers body assembly filled with titanium clamps and completing the firing. As a key component in the clamping process, the pliers body assembly is usually composed of a pliers rod and a left pliers head and a right pliers head respectively welded to the ends of the pliers rod and arranged relatively to each other to form a jaw. Because the performance requirements of the pliers head and the pliers rod are different, they cannot be formed as one piece during production. Instead, they are made separately and then the pliers head and the pliers body are fixed into a whole through a welding process. Because it is an assembled structure and a medical device used on the human body, there are high requirements for the closing accuracy of the pliers head after welding of the pliers body assembly and the matching dimensional accuracy of the welding point and the push tube. The traditional testing method is to perform a machine firing test after the overall titanium clamp is manufactured. If the test fails, the entire clamp can only be scrapped, which causes waste invisibly and increases the production cost accordingly. Utility Model Content
