Connecting process and connecting structure of endoscope tip head and snake bone

Abstract

The invention discloses a connecting process of endoscope tip head and snake bone, which comprises the following steps : step 1, expanding the pore diameter of the end tube section of the snake bone;step 2, opening the circumferential surface of the end tube section of the snake bone after expanding; step 3, inserting the connecting part of the endoscope tip head into the hole of the end tube ofthe expanded snake bone; step 4, welding and fixing the connecting part of the endoscope tip head to the end tube section of the snake bone at the opening. The connecting process of endoscope tip headand snake bone has the advantages that under the premise that the length of the connecting position is not increased and the overall outer diameter of the snake bone is not increased, the pore of theend tube section is enlarged and the opening is made on the upper side of the end tube section, and the connecting part of the endoscope tip head is welded with the snake bone at the opening so as toachieve the connection, and the flexibility of the snake bone is not reduced, at the same time, due to the adoption of welding connection, the snake bone and the tip head are firmly connected and cannot fall off. The invention also discloses a connecting structure of the endoscope tip head and the snake bone prepared by the connecting process, and connecting structure of the endoscope tip head and the snake bone has the advantages of simple structure, strong flexibility and firm connection.

Description

technical field [0001] The invention relates to the technical field of endoscopes, in particular to a connection process and a connection structure between a tip end of an endoscope and a snake bone. Background technique [0002] There are two main ways to connect the tip of the traditional endoscope to the snake bone: (1) by enlarging the diameter of the snake bone, the tip end is directly installed on the snake bone. Although this connection process can greatly shorten the length of the connection part, the outer diameter of the product is greatly increased due to the increase in the outer diameter of the snake bone; Connect with the snake bone and the ring part. This connection method can complete the connection without greatly increasing the outer diameter of the connection part, but the length of the connection part needs to be increased. Both of the above two methods lead to an increase in the parts that cannot be bent, which reduces the flexibility of the snake bone....

Problems solved by technology

Although this connection process can greatly shorten the length of the connection part, the outer diameter of the product is greatly increased due to the increase in the outer diameter of the snake bone; Connect with the snake bone and the ring part

This connection method can complete the connection without greatly increasing the outer diameter of the connection part, but the length of the connection part needs to be increased. Both of the above two methods lead to an increase in the parts that cannot be bent, which reduces the flexibility of the snake bone. sex
