Abstract

The invention discloses an intelligent positioning laparoscope puncture apparatus with safety protection function, which comprises a needle core, a cannula for inserting the needle core and a safety protection system for making the needle tip of the needle core automatically retract to the cannula after the puncture is finished; the safety protection system comprises an electromagnetic lock, an electromagnetic lock control system, a pressure signal transmission system, a spring assembly, an air guide groove and a lock hole formed on the needle body of the needle core, a lock cover formed on the wall of the cannula, and a top cover connected with the upper end of the cannula; after a signal of a pressure sensor in the pressure signal transmission system is received, the electromagnetic lock control system sends an unlocking instruction to the electromagnetic lock, and the electromagnetic lock is electrified and is in an unlocking state; and when the electromagnetic lock is in the unlocking state, the needle handle of the needle core is pushed to move upwards under the action of elasticity of a helical spring, so that the needle tip of the needle core automatically retracts to the cannula. Therefore, the intelligent positioning laparoscope puncture apparatus can greatly reduce accidental injury and complications in the laparoscope puncture process and improve the puncture safety.

Description

technical field [0001] The invention belongs to medical instruments, in particular to an abdominal wall puncture device used in laparoscopic surgery. technical background [0002] Laparoscopic surgery is one of the common clinical surgical methods. The abdominal wall puncture device commonly used in laparoscopic surgery consists of two parts: an external cannula and a needle core inserted in the cannula. After the trocar needle core guides the cannula to complete the puncture of the abdominal wall, the operator introduces the laparoscopic operating instrument through the instrument channel established by the cannula for intraperitoneal operation. When performing abdominal wall puncture, the operator often judges the depth and strength of the puncture device based on clinical experience. However, due to the individual differences in the thickness and toughness of the abdominal wall in different patients, and the shape of the abdominal wall during puncture is affected by the m...
