Description

Hemostatic fastener device with lining plate
Technical Field
The utility model relates to the technical field of medical equipment, concretely relates to hemostasis device especially relates to a take hemostasis spiral-lock device of welt.
Background
If more drainage tube bleeding is found after the cardio-thoracic surgery, secondary thoracotomy hemostasis must be performed urgently, wherein the bleeding reoperation rate after the intracardiac open-air surgery is about 2% -5%, and the bleeding reoperation rate after the general thoracic surgery is about 1%. The reasons for performing secondary thoracotomy hemostasis after operation comprise sternal incisions, sternal periosteum and marrow cavities, steel wire penetrating positions, arterial vascular beds in thoracic cage, intercostal muscles, intercostal blood vessels and active bleeding or oozing at rib stump positions, wherein secondary thoracotomy caused by sternal periosteal hemorrhage and sternal cavity bleeding accounts for more than 10% of all the causes.
Open heart surgery, particularly in extracorporeal circulation, typically involves a median sternal or intercostal incision. The median sternal incision requires sawing the entire sternum open and then using tools to open and expose the two sternal halves during surgery. In operation, the sternum is propped open, which easily causes sternal fracture and extensive bleeding of bone marrow cavity and periosteum, although strict hemostasis is usually performed by methods of smearing sternal tangent plane with bone wax, electrically coagulating hemostasis sternal periosteal edge, suturing broken small blood vessels near incision and the like in operation or before chest closure, after the patient is rewarming and blood pressure rises, the wound surface still can be subjected to extensive bleeding or continuous bleeding, further causing hemothorax or pericardial tamponade, and if the chest hemostasis is not performed immediately, the patient can be subjected to hemorrhagic shock, and the patient can be seriously killed. When closing the median incision of the sternum, a steel wire with a needle is generally selected to suture the left and right sternums and then to tie and fix the sternum, but the fixation of the steel wire to a certain extent can cause the sternum to be involuntarily uneven or the sternum to be opened, so that the sternum healing is delayed.
Open surgery for general thoracic surgery typically involves a trans-intercostal incision or a trans-costal incision, requiring a layer-by-layer incision of the skin, the subcutaneous fascia, the intercostal muscles, and the parietal pleura, optionally with or without rib disruption, and also requiring tools to open and expose both sides of the rib. The rib fracture and the intercostal muscle bleeding are easily caused by spreading the ribs on two sides in the operation. When closing the chest, the closing device is used to easily damage intercostal blood vessels, and if the rib periosteum incisal margin or parietal pleura incisal margin at the incision is not used for stopping bleeding completely, the blood pressure is increased after closing the chest, so that the hemothorax is more easily generated, and the drainage quantity of the thoracic drainage tube after the operation is large, and the chest can be opened again for stopping bleeding.
Because of rich blood supply, the bone surface bleeding and periosteal bleeding related to bone destruction are difficult to stop bleeding by the conventional methods such as electric coagulation, forceps, hemostatic gauze, gelatin sponge filling and the like. The commonly used clinical hemostasis method is to select bone wax to carry out hemostasis on the wound surface of the marrow cavity. The main components of the traditional bone wax are beeswax, vaseline and the like, and the bleeding point is sealed by the filling effect. However, the traditional bone wax has poor biocompatibility, is difficult to degrade and absorb by organisms, and can cause serious complications such as foreign body reaction, wound infection and the like after being left in bodies.
Chinese patent No. CN 109675094a the present invention discloses an absorbable bone wax with hemostatic function, which can be naturally degraded in vivo without causing complications related to the advanced period of residues while maintaining good hemostatic effect of the conventional bone wax. However, the invention still aims at the hemostasis of bleeding of the bone surface or the marrow cavity damaged in the operation, does not consider the bleeding of the bone membrane surface, and can not prevent the bleeding of other layers of the incision from continuously flowing into the pericardial cavity or the mediastinum.
Chinese utility model patent with patent number CN 208926475U discloses a sternum suture assembly capable of effectively avoiding bleeding caused in the process of sternum suture, wherein the hemostatic device comprises a hemostatic sleeve and two gaskets respectively positioned at two ends of the hemostatic sleeve. This embodiment need when carrying out the sternum suture after tightening up the steel wire, thereby the hemostatic sleeve pipe just can withstand both ends gasket and play the effect of oppressing the steel wire eye of needle and producing hemostasis. Obviously, the stop sleeve with proper thickness and hardness needs to be selected, the length needs to be adjusted according to the needle eye distance of the suture steel wires, and if the needle eye distance of the steel wires is too long, the hemostatic sleeve cannot jack the gaskets at the two ends, so that the compression hemostasis effect cannot be achieved; if the hemostatic sleeve is too long, it may cause compression on the heart located behind the sternum, and may also cause compression on the pericardial drainage tube and mediastinal drainage tube after operation. More importantly, the proposal solves the problem of hemorrhage of the needle eye, and does not solve the problems of pericardial stuffing, mediastinal hematocele and the like caused by sternal periosteal hemorrhage.
Chinese patent No. CN 110123428A provides a quick release sternum closure fixator, which can be opened smoothly and quickly by rotating a locking wheel to force two elastic claws to return to an initial state. Although the scheme replaces sternum steel wires, avoids cutting sternum and solves the problem of poor sternum involution, the problems of secondary surgical extraction and high economic cost still exist.
Therefore, the patent aims to provide a product design, which can perform effective compression hemostasis on bleeding points of parietal pleura or periosteum incisal margin of the chest wall of a sternum incision and avoid blood flowing into a chest cavity or a pericardial cavity, and can also improve the chest incision pair situation to a certain extent and is a safe and economical hemostasis device.
