An automatic venting laparoscopic trocar

Abstract

The invention discloses an automatic exhaust type laparoscopic trocar, belonging to the technical field of medical devices, comprising an automatic exhaust type laparoscopic trocar main body, and an absorption device is installed on the outer side of the automatic exhaust type laparoscopic trocar body; The absorbing device includes a first compression spring, medical cotton, a connecting ring, an outer ring body, an inner ring body, an accommodating groove, a second compression spring, a clamping hole and a clamping block. An inner ring body is installed on the outer side, an outer ring body is arranged on the outer side of the inner ring body, accommodating grooves are opened on the upper and lower sides of the inner ring body, and a second compression spring is installed on the inner side of the accommodating groove; the present invention By setting the absorption device, the laparoscopic trocar can absorb the blood flowing out of the patient's wound through the medical cotton during operation, thereby reducing the possibility of infection in the patient's wound, thereby improving the working ability of the laparoscopic trocar.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an automatic exhaust type laparoscopic puncture device. Background technique [0002] Medical devices refer to instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are directly or indirectly used on the human body, including required computer software. [0003] The prior art has the following problems: 1. Most of the current automatic exhaust type laparoscopic trocars have the problem that it is difficult to process the blood from the patient when they are working, thereby reducing the working capacity of the laparoscopic trocars; 2. Most of the automatic exhaust type laparoscopic trocars have the problem that users tend to slip due to hand sweat, thereby reducing the practicability of the laparoscopic trocars. Contents of the invention [0004] In order to solve the problems raised in the ab...

Problems solved by technology

[0003] The prior art has the following problems: 1. Most of the current automatic exhaust type laparoscopic trocars have the problem that it is difficult to process the blood from the patient when they are working, thereby reducing the working capacity of the laparoscopic trocars; 2. Most of the self-venting laparoscopic trocars have the problem that users tend to slip due to sweaty hands, which reduces the practicability of laparoscopic trocars
