Abstract

The invention belongs to the technical field of medical instruments, in particular to a double-joint surgical instrument. The present invention aims at the problem that the pincer head structure in the prior art can only be rotated in one direction, the operation is not flexible enough, and cannot meet the needs of complex surgical environments, and provides a double-joint surgical instrument. The present invention includes an outer shell, The wire passing cavity, the pincer seat, the first operating assembly, the second operating assembly, the pincer assembly, the second control rope is connected to the pincer assembly, a rotating assembly is arranged between the pincer assembly and the pincer seat, and the first The control rope is connected to the rotating assembly. The present invention uses the first operating assembly to control the rotation of the rotating assembly through the first control rope, and uses the second operating assembly to control the rotation of the pliers assembly through the second control rope. Since the pliers assembly is connected to the rotating assembly, it can be rotated by the rotating assembly. Driven to achieve multi-directional rotation, flexible operation, and can adapt to the needs of complex surgical environments.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a double-joint surgical instrument. Background technique [0002] Surgical forceps are mostly used in medical treatment to clamp human tissue during surgery. In the prior art, there are surgical forceps that control the rotation and opening and closing of the forceps head with a wire rope. [0003] For example, a Chinese invention patent application discloses a high-frequency electrosurgical forceps head [application number: 201610103263.4]. The invention patent application includes an outer catheter and a clamp arm. The front end of the catheter and the end of the clamp arm are fixed on the inner catheter through a connecting piece, protrusions are provided on the inside of the front end of the clamp arm, a hemostatic nail is provided in one of the protrusions, and a vacuum suction tube is provided on one of the clamp arms. A high-definition camera is arranged on t...
