Minimally Invasive Steering Soft Aspirator

Abstract

The invention discloses a minimally invasive steering soft aspirator, which comprises a soft aspirator tube and a near-end assembly of the aspirator with a steering control handle; The membrane tube is airtightly connected with the near-end component of the suction device; the proximal component of the suction device adjusts the steering of the tube with the membrane tube at the front end of the suction device through the steering control handle and the silk thread arranged on the soft tube of the suction device. The suction device of the present invention is easy to operate, safe to use, and has ultra-minimally invasive characteristics. It can pass through narrow linear or arc-shaped rigid passages, and the working direction of the suction device can be controlled by turning the steering control handle; there is no need to adjust the spatial position and location of the working passage. The space position of the main body of the suction device only needs to adjust the space position of the front end of the suction device, which reduces the iatrogenic damage of nerves, blood vessels and brain tissue, reduces the complications of nerve and blood vessel injuries during the perioperative period, and avoids uncoordinated operation by two people. The operation difficulty is reduced, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to an aspirator in medical equipment, in particular to a minimally invasive steering soft body aspirator. Background technique [0002] Aspirators are required to remove accumulated blood, fluid, necrotic tissue, tumor tissue, and bleeding blood vessel stumps in neurosurgery, otolaryngology and other surgical operations. The function of the aspirator is to absorb liquid, semi-solid, blood vessels, tumors and other substances during the operation, so as to clean the operation and expose the bleeding site. The principle of the aspirator is to suck the removable target substance into the pipeline through the pressure difference and remove it from the operation; or to absorb the target tissue to control its spatial position. The suction device can maintain a clean operating environment for the surgeon, and can absorb and control the spatial position of some target blood vessels, tissues, tumors, etc.; assist the surgeon to complete t...

AI Technical Summary

Problems solved by technology

[0003] Surgeons in neurosurgery, otolaryngology and other departments have found that existing aspirators have the following shortcomings in long-term surgical experience: (1) there are some blind spots and corners in neurosurgery operations, and traditional hard aspirators Ineffective operation, or frequent replacement of hard suction devices with different angles at the front end

Method 4, if the endoscope channel chooses a curved shape with a radian such as a curved guide, the existing suction device and other tools will not be used
