Disposable safety self-locking tube-placing device

Abstract

The invention relates to a disposable safe self-locking hose placing device, which consists of an upper clamping body, a lower clamping body, a rubber inner core and a jaw seat, wherein the upper clamping body and the lower clamping body are provided with a hollow through hole respectively; the lower part of the upper clamping body is provided with a hollow jaw; the rubber inner core is positioned in the hollow of the hollow jaw; the center of the jaw seat is provided with a through hole of a drainage hose, the side wall of the jaw seat is axially provided with a clamping groove which is connected with the hollow jaw, and the lower end of the hollow jaw is fixed in the clamping groove of the jaw seat; the lower clamping body is sleeved outside the hollow jaw and the jaw seat, and limitedby the jaw seat to downward push the upper clamping body; and the hollow jaw provided with taper is pressed by the lower clamping body to shrink and squeeze the rubber inner core inside so as to tightly press and fix the drainage hose in the rubber inner core. The device has the advantages of simple structure and convenient hose placing operation, and can adjust the hose placing length to meet clinical requirements, and effectively avoid the pull-away and blockage of the drainage hose. After disposable use, the device can be self-destructed so as to avoid the infection risk caused by using the product once again.

Description

Disposable safety self-locking tube insertion device technical field The invention relates to a medical device, in particular to a disposable safety self-locking tube insertion device. It is mainly used for minimally invasive craniocerebral surgery to fix the drainage hose and self-lock after use, so that the product can self-destruct and avoid cross-infection caused by moving the drainage hose and secondary use. Background technique We know that in recent years, minimally invasive tube placement has become a new and effective method for the treatment of hypertensive cerebral hemorrhage. In clinical practice, it is necessary to drill holes in the skull and place medical hose drainage. To fix the flexible tube, surgical operations such as tightening the flexible tube after suturing the scalp are often used clinically. This method takes a long time to operate, is complicated and requires suturing the wound of the patient. The connection of the drainage hose is also not reli...

We know that in recent years, minimally invasive tube placement has become a new and effective method for the treatment of hypertensive cerebral hemorrhage. In clinical practice, it is necessary to drill holes in the skull and place medical hose drainage. To fix the hose, surgical operations such as suturing the scalp and then tightening the hose are often used clinically. This method takes a long time and is complicated and requires suturing the wound of the patient

Drainage hose connection is not reliable enough, convenient

At present, there is no special disposable safe self-locking tube insertion device
