Description

A puncture and drainage tube fixing device for thoracic and cardiothoracic surgery

technical field

The invention relates to the technical field of auxiliary medical instruments for thoracic and cardiac surgery, in particular to a puncture and drainage tube fixing device for thoracic and cardiac surgery.

Background technique

Cardiothoracic surgery includes diseases of cardiac surgery and general thoracic surgery. Cardiovascular surgery studies heart and great vessel trauma, pericardial disease, congenital heart disease, acquired heart valve disease, ischemic heart disease, heart tumor, great vessel disease, intervention Drainage tubes are often used in therapeutic procedures, surgical treatment of cardiac arrhythmias, cardiac pacing and implantable defibrillators, dynamic cardiomyoplasty, heart, lung, and heart-lung transplantation.

At present, the drainage tube is used as a conventional auxiliary tool in the process of thoracic and cardiac surgery. The existing drainage tube is mostly positioned through the external adhesive tape during use. Because the adhesive tape is easy to loose due to sweating, And it is inconvenient to clean up the puncture. In addition, there are also some special positioning devices, such as the Chinese patent No. 202122704460.0, which discloses a puncture and drainage tube fixing device for thoracic surgery. When in use, the locking block is engaged with the docking block, so that Fixing between the strap and the human body enables the position of the device to be effectively positioned, effectively avoiding the phenomenon of loosening of the patient's activities. During drainage, the drainage tube is passed through the ring, and then fixed by the clamp block. When adjusting the angle, you can loosen the positioning nut to adjust, and after the adjustment, you can fix it; although this device can achieve positioning, its height is too prominent, and the installation of the drainage tube is inconvenient, which is easy to cause If it is accidentally touched, and the anti-slip pad at the bottom of the catheter string acts directly above the threading position, it is not easy to clean and will bring a burden to the threading position. Therefore, there is an urgent need for a positioning device that is convenient for the installation of the drainage tube and does not affect the cleaning of the threading position.

Detailed ways

In order to achieve the above purpose and effects, the technical means and structures adopted in the present invention will be described in detail in terms of the features and functions of the preferred embodiments of the present invention in conjunction with the accompanying drawings.

As shown in Figures 1-3, the present invention provides a puncture and drainage tube fixing device for thoracic surgery, including a base 1; both sides of the base 1 are provided with straps 2 for fixing the base to the body; One side of the top of the base 1 is provided with a boss; the side of the top of the base 1 opposite to the boss is slidably provided with a clamping block 4; a drainage tube passing groove is formed between the clamping block 4 and the boss; The bottom of the clamping block 4 is provided with a plurality of support plates 44; the side of the support plate 44 away from the boss is provided with a slide bar 43; the top of the base 1 is correspondingly provided with a plurality of chutes matching the support plates 44 15; the chute 15 is provided with a spring 42; the spring 42 is sleeved outside the slide bar 43; one end of the spring 42 abuts against the support plate 44, and the other end abuts against the side wall of the chute 15; The side of the base 1 away from the boss is correspondingly provided with a plurality of sliding holes 16 matched with the sliding rods 43 . When in use, fix the base on the user's body through the strap 2, so that the base is located below the puncture position; slide the clamping block 4 outward by hand, and then place the drainage tube 3 into the space between the clamping block 4 and the boss. The drainage tube passes through the groove, and then the clamping block 4 is released. Under the action of the spring 42, the clamping block 4 rebounds automatically, and the drainage tube 3 is clamped.

In another embodiment, the end of the base 1 away from the puncture position is provided with a drainage tube clip 7 . When the drainage is not needed, use the drainage tube clamp 7 to clamp the drainage tube 3 to prevent further drainage.

In another embodiment, the side of the clamping block 4 close to the boss is provided with two guide wheels 41 for rotation; the edge part of the guide wheels 41 is located in the passage groove of the drainage tube; the top of the clamping block 4 A first cover plate 5 is provided. The drainage tube 3 is clamped by the guide wheel 41 to avoid excessive friction of the drainage tube 3 .

In another embodiment, a groove 12 is opened on the top of the boss; a rack 13 is obliquely arranged in the groove 12; a gear 11 is engaged on the rack 13; Two cover plates 6; the second cover plate 6 seals the drainage tube through the top of the groove to prevent the drainage tube 3 from coming out of the drainage tube through the groove; when the gear 11 is positioned at the end of the groove 12 near the puncture position, the gear 11 is opposite to the guide wheel 41 close to the puncture position, and the distance between the two is equal to the diameter of the drainage tube 3; 41 opposite, and the spacing between the two is equal to twice the wall thickness of the drainage tube 3 . Through the above settings, when the drainage tube 3 moves to the puncture position, the gear 11 is driven to move to the puncture position, and then the gear 11 is moved out of the drainage tube to pass through the groove position, which facilitates the movement of the drainage tube 3. When the drainage tube 3 moves away from the puncture position , drive the gear 11 to move away from the puncture position, and then make the gear 11 gradually occupy the space where the drainage tube passes through the groove, so as to limit the movement of the drainage tube 3 and prevent the drainage tube 3 from coming out.

In another embodiment, the materials of the rack 13 and the gear 11 are both iron; the end of the rack 13 away from the puncture position is provided with a magnet 14 so as to provide the gear 11 with a force to move away from the puncture position, Provide better restriction effect.

The above is only a preferred embodiment of the present invention, not all embodiments, anyone should know that the structural changes made under the inspiration of the present invention, all technical solutions that are the same as or similar to the present invention belong to protection scope of the present invention.
