Abstract

The invention discloses a virtual laparoscopic surgery simulator with a force feedback function. The simulator is used for assisting surgeons in completing simulated training of laparoscopic surgeries, and comprises the following five parts, wherein the first part comprises a metal frame and a guide rail, the metal frame is used for supporting the whole simulator, and the guide rail is fixed to the metal frame to support trays so that the trays can slide leftwards and rightwards on the guide rail or can be fixed to the guide rail; the second part comprises the metal trays and components used for fixing force feedback devices, and the components are mainly used for lifting up the force feedback devices and enabling the force feedback devices to be fixed to the trays when the force feedback devices are placed on the trays; the third part comprises the two force feedback devices (Phantom Omni) which are core components of the virtual laparoscopic surgery simulator; the fourth part comprises two laparoscopic surgery forceps connected with the force feedback devices (Phantom Omni); the fifth part comprises a rubber plate with holes, and the rubber plate is fixed to the upper surface of the metal frame and used for simulating the belly of a human body.

Description

technical field

[0001] The invention relates to a virtual laparoscopic operation simulator with force feedback. Background technique

[0002] With the continuous expansion and deepening of the application of virtual reality (VR) technology in the medical field, virtual surgery (Virtual Surgery) and VR surgical simulators have attracted more and more attention. Take the currently popular laparoscopic minimally invasive surgery as an example. This kind of surgery makes a hole in the patient's abdomen, and inserts surgical instruments and cameras deep into the abdominal cavity. Reduce the wound, reduce the pain of the patient, and shorten the recovery time of the patient. This surgical method has brought good news to patients, but it puts forward higher requirements for doctors. Doctors must undergo sufficient training to master their eye-hand coordination and be competent for corresponding operations. Current training for this type of surgery is usually done on cadavers, ani...

Embodiment Construction

[0034] A virtual laparoscopic surgery simulator with force feedback of the present invention, its detailed production process includes the following five steps:

[0035] Step (1), making metal frame and guide rail. Dimensions such as figure 1 shown. The parameters of the length, width and height of the metal frame are the dimensions of the outer edge. The thickness of the metal frame material is 3-4 cm, which is more suitable. The material is required to be light, strong, durable, and will not rust. Among them, the connection of the metal strips can be connected by a 45-degree triangular metal block through upper screws. If you use welding, it will be inconvenient to disassemble and not beautiful. The width of the slide rail is designed to be 7-9 cm, so that the tray is placed on it more stably. The thickness of the slide rail is designed to be 4 to 5 cm, so that it can be fixed at a certain position on the slide rail by tightening the screws under the tray.
