Abstract

The invention discloses a self-locking fixing column used for minimally invasive surgery. The self-locking fixing column comprises a positioning sleeve, a locking block and a central column, wherein the central column is arranged in the positioning sleeve, an opening is formed in the side wall of the positioning sleeve, the locking block is arranged in the opening and is in clamping connection with the central column, through the clamping of the locking block, the upward displacement along the central column generated by the positioning sleeve can be limited. The self-locking fixing column iscompact and simple in structure, convenient to assemble and disassemble, and easy to operate, the purpose that a doctor does not need to consider the connecting instability and easy slippage among theconnecting parts during the surgery process is satisfied, the occurrence of unnecessary potential safety hazards during the surgery process is greatly reduced, and then the surgery is carried out smoothly.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a self-locking fixing post for minimally invasive surgery. Background technique [0002] Minimally invasive surgery is one of the achievements of high-tech surgical technology across the century in the clinical medical field; the representative of minimally invasive surgical instruments is the endoscope; if a keyhole-sized hole or a small incision is used, it can perform resection of abdominal visceral lesions, deformities, etc. Various surgical operations such as correction, repair or reconstruction, and finally achieve the purpose of treatment; minimally invasive surgery is different from surgical operations in the last century in that the former can reduce the area of ​​surgical wounds, avoid infection caused by large exposure of internal tissues, and Can make patients recover faster, shorten hospital stay and medical expenses. Minimally invasive surgi...
