Drop needle detecting device with handle anastomat punch head and detecting method thereof

Abstract

The invention relates to a drop stitch detecting device on the head of a stapler with a hand lever and a detection method thereof. The drop stitch detecting device comprises a computer, a video camera, an illuminant light and a stapler locating device; the video camera comprises a CMOS picture sensor and a lens; the stapler locating device comprises a pedestal, a stapler clamp, an illuminant rack, a video camera rack, an upright post and a winding gear; the stapler clamp comprises a sliding panel, a component sliding stand, a teeth bar, a fixed pedestal, a dirigible wheel, locking apparatus and a ledger plate; the sliding panel is fixedly arranged on the sliding stand; the ledger plate is fixedly arranged on the fixed pedestal; the teeth bar is arranged on the component sliding stand; and the dirigible wheel and the locking apparatus are arranged on a lateral surface. Based on the reflection image principle, the drop stitch detecting device adopts a low-angle ring light frontal projection manner for detection. The drop stitch detecting device and the detection method thereof solve the drop stitch detection problem of the stapler with the hand lever, increase the product qualified rate and safety, avoid the human misjudgment, increase the detection efficiency, ensure the product quality, have the advantages of high accuracy, high speed and compact structure and design. Furthermore, the invention is suitable for popularization and use.

Description

technical field [0001] The invention relates to an instrument for detecting a missing needle of a stapler, in particular to an online automatic detection device and a detection method for a missing needle of an anastomat with a handle based on the principle of reflection imaging. Background technique [0002] The shell of the needle holder of the stapler is made of plastic material, and there are two rows of interlaced staples arranged in a circle in the needle groove of the head of the needle holder, and then connected to the firing handle. In digestive tract surgery, hold the handle to fire the staples, drive the staples into the tissue, and cut off the inner tissue with a circular knife at the same time, so that the anastomosis of the lumen and organs can be easily performed. Stapler staples are made of metal titanium or tantalum. The staples are thin (0.11-0.13mm), large in number (at least 16), and have short legs that are easy to fall off. If the nail is missed, it ma...

Problems solved by technology

However, this system is not suitable for missing needle detection on the head of a stapler with a handle. The main technical problem is that the system uses a backlight lighting system, and the principle of transmission imaging cannot collect the original image of a stapler with a handle. The detection of the stapler, and the fixture in the stapler positioning device cannot meet the clamping and adjustment of the stapler with handle
