Problems solved by technology

Doctors need to carry out visual inspection during the operation, which distracts their attention. In addition, because there is no uniform standard, in laparoscopic surgery, the deflection of the lens direction often occurs, resulting in misjudgment of the surgical field of view.

Embodiment

[0013] Such as figure 1 Shown, a kind of laparoscopic lens deflection automatic warning device, it is made up of gyroscope, single-chip microcomputer, alarm, power supply, wireless network and upper computer, described gyroscope, single-chip microcomputer, alarm and power supply are connected by circuit, and described gyroscope The instrument is used to measure the deflection angle of the laparoscopic lens and transmit the data to the single-chip microcomputer. The single-chip microcomputer is used to judge whether the deflection angle data is within the set value and control the alarm to send an alarm. The single-chip microcomputer is connected to the host computer through a wireless network. The wireless network is used to convert the deflection angle data of the single-chip microcomputer into a wireless signal and send it to the host computer. The host computer performs real-time geometric correction on the laparoscopic image according to the rotation angle data, thereby cor...

Abstract

The invention discloses an automatic alarming device for laparoscopic lens deflection. The invention can automatically alarm the deflection of the laparoscopic lens, so that the doctor can correct the orientation of the laparoscopic lens at any time in the process of viewing the image to avoid surgical errors, and at the same time, it can automatically perform real-time geometric correction on the laparoscopic image to correct Image distortion caused by rotation further reduces surgical errors. The invention has the advantages of simple structure, convenient operation and the like.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an automatic warning device for laparoscopic lens deflection. Background technique [0002] Laparoscopic surgery is a commonly used minimally invasive surgical method. It makes a hole through the abdominal wall and inserts long rod instruments into the abdominal cavity for surgical operations. Compared with traditional open surgery, laparoscopic surgery has less trauma, less bleeding, and faster recovery. About 70% of the total abdominal surgery is done through laparoscopy. [0003] During laparoscopic surgery, the direction of the operator's field of view is determined by the direction of the lens. At present, the lens used in clinical laparoscopy has no direction prompt, and the doctor who holds the lens needs to control it according to experience. Doctors need to perform visual inspection during the operation, which distracts their attention. In addition, because...
