Problems solved by technology

But for novices, it is relatively difficult to perform unskilled abdominal wall puncture on the human body and judge whether the puncture is successful based on the feeling
This also increases the relative risk of intra-abdominal organ injury

Embodiment 2

[0018] Example 2 as Figure 4 As shown, the integrated circuit board is integrated with a pressure sensor, a signal converter, and a Bluetooth transmitter module to ensure that the puncture device has the function of measuring and transmitting pressure data, and sends the continuously changing pressure data during the puncture process to the corresponding Computer; said computer refers to a computing device with Bluetooth receiving function, computing function, display function and sounding function, including tablet computer, mobile phone, ordinary computer, etc. The received pressure data can be recorded in time, depicted as a pressure curve, and displayed on the computer screen; at the same time, the software can identify the pressure data that suddenly drops when the puncture needle core breaks through the peritoneum, and make the computer send out an alarm, prompting The surgeon's puncture needle has broken through the peritoneum and entered the abdominal cavity.

Abstract

The invention discloses a puncture device for laparoscope operation capable of automatically warning, and belongs to a puncture device capable of automatically warning when an abdominal cavity puncture needle passes through the peritoneum for reminding an operator that the puncture needle passes through the peritoneum. A pair of chutes (1-1) are symmetrically formed in the inner wall of a puncture needle tube (1) relative to the axial line, the lower part in the puncture needle pipe is provided with a sensor plate (1-3), a pressure spring (1-2) is positioned on a pressure sensor (1-3-1) positioned in the center of the sensor plate, the outer surface of a puncture needle core (2) is symmetrically provided with a pair of slide rails (2-1) relative to the axial line, the puncture needle core is positioned in the puncture needle tube, the chutes and the slide rails are embedded, a pressure sensor, a signal converter (1-3-2) and a Bluetooth emitting module (1-3-3) which are in sequential serial connection are arranged on the sensor plate, and the signals are sent to a corresponding computer (3) through the Bluetooth emitting module.

Description

technical field [0001] The invention relates to a laparoscopic operation puncture device capable of automatic alarming and belongs to the technical field of medical instruments. Background technique [0002] With the further development of minimally invasive surgery, laparoscopic surgery technology has become more mature, and the operation skills of surgeons have become more proficient. [0003] However, whether it is a general surgery doctor or a gynecologist, they must perform the same operation before performing laparoscopic surgery, that is, abdominal wall puncture. Only after successful puncture, laparoscopic surgery can proceed normally. [0004] The first step of abdominal wall puncture is blind puncture, which is also the difficulty of abdominal wall puncture. The existing abdominal wall puncture device, the Veress needle, does not have the function of prompting the puncturer whether the puncture is successful. For experienced surgical operators, the success of th...
