Problems solved by technology

[0003] 1. Using the traditional poke puncture device, the operator cannot accurately and effectively control the entry length of the puncture device, which may cause damage to the thoracoabdominal organs by the puncture device
[0004] 2. When the pneumoperitoneum is not fully established and the lungs are not completely collapsed, the surgeon cannot precisely control the strength, which may cause collateral damage to the patient, increasing the possibility of surgical complications and surgical risks

Abstract

The invention relates to a precise puncture device and method for endoscopic surgery, and belongs to the technical field of medical instruments.The puncture device comprises an outer tube and an inner tube, the outer tube and the inner tube are each of a cylindrical cavity structure, the head of the outer tube is sharp and is made of a disposable transparent material, scales are arranged on the outer wall of the front end of the outer tube in the height direction of the outer tube, and the inner tube is made of a transparent material. The thickness of the chest wall or the abdominal wall of a patient can be measured according to thoracic and abdominal CT images, the puncture depth can be adjusted, the possibility that organs of the patient are damaged by a puncture device is reduced while efficient and accurate puncture is achieved, the inner tube and the outer tube are both made of disposable materials, and the puncture device is convenient to use. The problems that a traditional puncture outfit is difficult to clean and disinfect incompletely due to repeated use are solved, and hospital infection is avoided.

Description

technical field [0001] The invention relates to a precise puncture device and method used in laparoscopic surgery, belonging to the technical field of medical devices. Background technique [0002] The current clinical method of puncturing at the site of the surgical approach is to use a poking puncture device. The disadvantages are as follows: [0003] 1. Using the traditional poke trocar, the operator cannot accurately and effectively control the entry length of the trocar, which may cause damage to the thoracoabdominal organs by the trocar. [0004] 2. When the pneumoperitoneum is not fully established and the lungs are not completely collapsed, the surgeon cannot accurately control the force, which may cause collateral damage to the patient, increasing the possibility of surgical complications and surgical risks. [0005] Therefore, there is a need for a new precise puncture device capable of precise puncture in laparoscopic surgery. Contents of the invention [0006...
