Surgical tissue closing device with visual function

Abstract

The invention relates to a surgical tissue closing device with a visual function, comprising a handhold device and a signal receiving and playing system, wherein the handhold device comprises a drive device used for supplying closure and firing needed power, a tissue closing assembly used for implementing a surgery by making use of the power supplied by the drive device, a micro camera used for collecting video signals, a signal processing device used for converting the video signals collected by the micro camera to digital signals and a signal sending device used for sending the digital signals; and the signal receiving and playing system comprises a signal receiving device used for receiving the digital signals sent by the handhold device, a signal processing device used for converting the received digital signals to video signals and a display terminal used for playing the video signals. The invention obtains the video signals through the micro camera arranged on the handhold device and transfers the video signals to a video receiving and playing system, thereby realizing real-time monitoring in the operation process of the surgery and assisting accurate location.

Description

technical field [0001] The invention belongs to the field of surgical instruments, and relates to a tissue closure device used under an endoscope. Specifically, the invention relates to a surgical tissue closure device with a visual function. Background technique [0002] Endoscopic surgical instruments are often preferred over traditional open surgical instruments because of the smaller incisions, faster postoperative recovery, and fewer complications. Therefore, the endoscopic surgical instruments that precisely place the distal end effector on the site to be operated through the trocar cannula are developing rapidly. There are two main categories of these actuators for the incision. Nails, sutures, closure clips, anastomotic rings, etc., and the other is the use of energy, such as ultrasonic knife, electric knife, laser knife, etc. Energy incision is mainly used in tissues with no blood vessels or only small blood vessels. Relatively speaking, the application of mechanic...

Problems solved by technology

When used under the endoscope, there is also the disadvantage that the eye is not wide enough and the viewing angle is easily limited

[0006] Similarly, the tissue closure devices used under other endoscopes all have the disadvantages that the eyes are not wide enough and the viewing angle is easily limited.
