Visual puncture outfit with puncture head convenient to replace

Abstract

The invention discloses a visual puncture outfit, and the puncture outfit comprises a main body structure, a puncture mechanism and a first auxiliary mechanism; the main body structure comprises a puncture sleeve, anti-skid lines, an anti-skid pad and a limiting groove; the anti-skid lines and the anti-skid pad are arranged on the puncture sleeve; the puncture mechanism comprises a connecting block, a handle rod, a protruding block, a fastener, a puncture rod and an anti-skid strip; the left end of the connecting block is connected with the second auxiliary mechanism through the puncture rod, and the first auxiliary mechanism is arranged in the puncture mechanism. According to the visual puncture outfit with the puncture head convenient to replace, the second camera is arranged and can shoot the position of the puncture head in the abdominal cavity, so the puncture head is prevented from accidentally puncturing viscera or other normal tissues of a patient, potential safety hazards are reduced conveniently, and meanwhile, when the puncture head needs to be cleaned or replaced, a worker can manually pull out the puncture head from the puncture rod, so the puncture head can be replaced, and the disassembly process is simple.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a visible puncture device for convenient replacement of a puncture head. Background technique [0002] The trocar is a surgical instrument that cooperates with minimally invasive equipment to provide instrument access for minimally invasive abdominal and pelvic surgery. At the same time, the trocar has the advantages of simple operation, low intraoperative risk, small wound, and easy recovery. The visible trocar is a kind of trocar. Most of the existing visual trocars have a fixed and single viewing angle, so it is easy for the surgical instrument to block the camera during the operation, which affects the normal operation of the operation. On the one hand, the existing visual puncture device is easy to puncture the viscera or other soft tissues in the patient's abdominal cavity when using the puncture head to puncture, which has a relatively large safety hazard.

Problems solved by technology

[0003] The object of the present invention is to provide a visual puncture device that facilitates the replacement of the puncture head, so as to solve the problem that most of the existing visible puncture devices proposed in the background art have a fixed and single viewing angle, which is easy to appear during the operation. The phenomenon that the surgical instrument blocks the camera affects the normal operation, and the existing visual puncture device is easy to stab the viscera or other soft tissues in the patient's abdominal cavity when the puncture head is used for puncture, which has a large safety hazard. Some puncture heads are mostly fixed in structure and inconvenient to disassemble and replace.
