Description

Technical Field

[0001] The utility model relates to the technical field of clinical vascular surgery, in particular to a thrombus aspirating device for clinical vascular surgery. Background Art

[0002] Vascular surgery is a branch of surgery, mainly aimed at the prevention, diagnosis and treatment of peripheral vascular diseases other than cerebrovascular and cardiac blood vessels. In addition to hair, nails, cornea, etc., the human body has blood vessels throughout the body. Thrombi are small pieces of blood formed on the surface of the peeling or repaired inner surface of the blood vessels in the cardiovascular system. In the variable fluid-dependent type, thrombi are composed of insoluble fibrin, deposited platelets, accumulated white blood cells and trapped red blood cells. The most common characteristics of clinical thrombosis patients are familial inheritance, recurrent attacks, severe symptoms, abnormal site of thrombosis formation, and young onset of disease. Treatment of thrombosis is a necessary measure to improve the health standards of the whole people.

[0003] Chinese patent CN215018472U discloses a thrombus suction device for vascular surgery, including a catheter and a guide tube, a bottom box and a push box, the push box is buckled and installed on the upper part of the bottom box, and the push box slides up and down on the upper part of the bottom box, a plurality of groups of lower pressure wheels are rotatably installed on the inner bottom of the bottom box, and a plurality of groups of upper pressure wheels aligned with the lower pressure wheels are rotatably installed on the inner top of the push box, through the design of the bottom box and the push box, the upper and lower pressure wheels and other structures, the catheter of the thrombus suction device can be straightened by the upper and lower pressure wheels inside the two box bodies, and the medical staff can press the upper and lower pressure wheels by holding the bottom box and the push box during use, so as to adjust the longer catheter, so as to extract the thrombus in a certain way, and the catheter will be bent during the process of pushing the catheter, which affects the extraction of the thrombus, and the positioning structure and the telescopic column structure are used to position and rebound between the bottom box and the push box, so as to facilitate the use of the staff.

However, during the thrombus absorption process, only the thrombus can be sucked out, and the harder and larger thrombus cannot be absorbed, which increases the difficulty of the operation and reduces the absorption effect. Therefore, a clinical vascular surgery thrombus absorption device is proposed to solve the above problems. Utility Model Content

[0032] The standard parts used in this application can all be purchased from the market, and special-shaped parts can be customized according to the instructions and drawings.

The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0033] If the present application discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously not possible to use an one-piece molding process).

[0034] The working principle of the above embodiment is:

[0035] (1) In the field of clinical vascular surgery technology, when the suction device is needed to suck out thrombi in a patient's blood vessels, the user first holds the handle 3 of the thrombus suction device, moves the suction tube 2 into the patient's blood vessels, and then covers the thrombi to be removed with the cover 506. After the thrombi are covered, the micro motor 501 is started to drive the transmission rod 503 to start rotating. The rotation of the transmission rod 503 drives the turntable 504 to start rotating. The rotation of the turntable 504 drives a plurality of crushing blades 505 to start rotating. As the crushing blades 505 rotate, the harder and larger thrombi are crushed.

[0036] (2) Simultaneously, the suction pump 604 is started. Due to the suction force of the suction pump 604, the crushed thrombus in the suction tube 2 is sucked into the collection box 601 through the first suction tube 605 and the second suction tube 606. Then, the thrombus is filtered by the filter plate 603 inside the collection box 601 to separate the thrombus from the blood. When the collection box 601 needs to be maintained regularly, the box cover 602 is opened, and then the thrombus filtered out by the filter plate 603 is cleaned out.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0038] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
