Problems solved by technology

At present, the puncture positioning technology mainly has the following technical problems in the use process: one is that the puncture positioning device cannot maintain the correct position of the needle insertion point, the needle insertion angle and the needle insertion depth; the other is the needle insertion positioning The device cannot be fixed. The second is to use adhesive tape or clamps to fix it. First, after the needle insertion angle and depth break away from the fixing effect of the positioning device, the puncture needle is easy to collapse or tilt. If the puncture needle breaks away from the tissue fluid level in the chest , it is likely to lead to air suction, which may easily lead to damage to the health of the patient.
[0003] The Chinese patent with the publication number CN209316013U discloses a puncture positioning device for thoracic surgery drainage, including a positioning base, a positioning sleeve is arranged on the positioning base, and an outer clip is provided on the top of the positioning sleeve The inside of the positioning sleeve is provided with an inner chuck, the inner chuck is a spring chuck and a threaded protrusion is provided on its side, and the side of the positioning sleeve is provided with a channel for passing through the threaded protrusion. hole, the outside of the positioning sleeve is provided with an adjusting nut that matches the inner chuck. This positioning device can ensure uniform puncture force and search for positioning mark points, but this device does not describe the above two technical problems in detail.

Abstract

The invention provides a drainage, puncture and positioning device for the cardiothoracic surgery. The device comprises a fixed sleeve, telescopic movable brackets, a fixing assembly and automatic supporting assemblies, wherein the fixing assembly and the fixed sleeve are rotationally connected through a rotating assembly, each telescopic movable bracket comprises a support I and a support II, thefixed sleeve and the support I are rotationally connected through a rotating assembly, one end, away from the fixed sleeve, of the support II is rotationally connected with the fixing assembly through a universal ball joint, and a plurality of automatic supporting assemblies are arranged on the fixing assembly in a matched manner. According to the four telescopic movable brackets, the inclinationdegree of the fixed sleeve can be adjusted by adjusting length of each telescopic movable bracket, and puncture demands of different parts in the thoracic cavity are met; and with adoption of the fixing assembly, air in a fixing rod is discharged by a push rod, so that the fixing rod is tightly adsorbed on the skin surface, adsorption and fixing functions are realized, the device can keep unchanged at a correct needle inserting point, a correct needle inserting angle and a correct needle inserting depth, and the inserted puncture needle is continuously fixed.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a drainage puncture positioning device for thoracic and cardiac surgery. Background technique [0002] Thoracic shell puncture is a very effective first aid method. At present, the puncture positioning technology mainly has the following technical problems in the use process: one is that the puncture positioning device cannot maintain the correct position of the needle insertion point, the needle insertion angle and the needle insertion depth; the other is the needle insertion positioning The device cannot be fixed. The second is to use adhesive tape or clamps to fix it. First, after the needle insertion angle and depth break away from the fixing effect of the positioning device, the puncture needle is easy to collapse or tilt. If the puncture needle breaks away from the tissue fluid level in the chest , it is likely to lead to cavitation, which will easily lead to damag...
