Automatic drag hook device for open-heart surgery

Abstract

The invention discloses an automatic drag hook device for an open-heart surgery. The automatic drag hook device comprises a breastbone expander and a supporting device arranged on the breastbone expander. A fixed installation strip is arranged at the upper portion of a movable arm and / or a fixed arm of the breastbone expander. The supporting device is clamped on the fixed installation strip. The supporting device comprises a fixed block, a supporting frame and a drag hook slide block, wherein the supporting frame is fixedly installed on the fixed block and provided with a sliding shaft, the drag hook slide block is arranged on the slide shaft, slides on the slide shaft and is provided with an installation hole for installing a hook and a fixed bolt hole, and the drag hook slide block and the slide shaft are connected and fixed through a locking bolt in the fixed bolt hole. After the automatic drag hook device is used, one surgical assistant can be omitted, and work efficiency is improved; influences of the assistant on surgical region exposure can be avoided, and surgical time can be shortened; the assistant can directly view the surgical operation process due to good exposure, and clinical teaching is facilitated.

Description

technical field [0001] The invention relates to a cardiothoracic surgical instrument, in particular to an automatic hook device for open-heart surgery. Background technique [0002] In open-heart surgery, median sternotomy is often used. In addition, due to the deep anatomical position and complex structure of the heart, the surgical field is small and exposure is difficult. Clinically, it is often necessary for the assistant to pull the inner heart structure with both hands, but on the one hand, the assistant is prone to fatigue after prolonged stretching, which will cause the retractor to displace and affect the surgical exposure, and the repeated adjustment of the retractor will waste the operation time; When stretching and exposing, it will occupy the space around the operative field, thereby affecting the operation of the operator; in addition, when the assistant uses both hands to stretch and expose, the operation process is often unable to directly see the operative f...

Problems solved by technology

[0002] Open-heart surgery often uses median sternotomy, and because of the deep anatomical position and complex structure of the heart, the surgical field is small and exposure is difficult

Clinically, it is often necessary for the assistant to pull the inner heart structure with both hands, but on the one hand, the assistant is prone to fatigue after prolonged stretching, which will cause the retractor to displace and affect the surgical exposure, and the repeated adjustment of the retractor will waste the operation time; When stretching and exposing, it will occupy the space around the operative field, thereby affecting the operation of the operator; in addition, when the assistant uses both hands to stretch and expose, the operation process is often unable to directly see the operative field, which is not conducive to the cooperation of the operation, which not only prolongs the operation time, but also It is not conducive to the advancement of assistant surgical techniques, resulting in slow growth of cardiac surgeons

[0003] After searching, it was found that the Chinese invention patent named "Automatic Left Atrium Retractor" has the application number "87214421.6". This invention connects the automatic retractor with the sternal retractor through "I"-shaped nails. Once the sternal retractor is opened during the operation, the adjustment range of the retractor installed above is very small, and it is difficult to remove or replace the retractor during the operation; due to improper operation, it is easy to cause damage to the tissues in the heart and chest. The surgical site also requires an assistant to use a retractor for manual cooperation, which is extremely inconvenient to operate
