Description
Technical Field
The invention belongs to the technical field of medicine, and relates to a cutting-prevention hemostasis device, in particular to a sternum suture cutting-prevention hemostasis gasket.
Background
The median sternal incision is a standard extracorporeal circulation direct-view cardiac operation incision, namely, the sternum is completely cut into left and right halves from the xiphoid process to the manubrium of the chest, and after the operation is completed, the left and right halves of the sternum are sutured. The sternum suture method usually adopts a steel wire fixing method, and single-needle intermittent fixing and 8-shaped fixing are common fixing methods.
The steel wire fixing method has the advantages of convenient operation, exact fixation, economy, practicability and the like; but also has some disadvantages, and the poststernal steel wire eye bleeding is a common complication of the steel wire fixation method. The steel wire passes through the intercostal cartilage space and is easy to injure the internal thoracic artery; the steel wire is easy to cause the bleeding of marrow cavity when passing through the sternum stem and the corpus sternum. The chronic hemorrhage after operation drains only tens of milliliters of blood per hour after operation, but the chronic hemorrhage lasts for tens of hours after operation; moreover, such bleeding is more insidious and deep, and may be difficult to detect when closing the chest or difficult to detect when hemostasis is achieved. During tightening and after fixation of the steel wire, the steel wire can cut the sternum due to activities such as breathing and cough, so that the bleeding probability of the sternum of a patient is increased, even the sternum of part of patients is open, and the treatment of complications is extremely troublesome. The research of multiple centers finds that the ratio of thoracotomy hemostasis again caused by steel wire eye bleeding behind the sternum can reach 2-3% of the total number of hands; however, the sternal opening not only seriously affects the respiration and circulation of patients, but also easily causes infection, and the death rate of sternal infected patients is nearly 20%.
To this end, a sternal suture assembly (application No. 201820924074.8) having hemostatic function has been proposed, which comprises a steel wire, a hemostatic device, and a needle connected to one end of the steel wire; the hemostatic device comprises a degradable hemostatic sleeve and two gaskets respectively positioned at two ends of the hemostatic sleeve; the steel wire can freely pass through the hemostatic sleeve and the gasket. The length of the hemostatic sleeve is fixed, but the distance between two needle holes can not be matched with the length of the hemostatic sleeve in the operation, which adversely affects the operation duration and the sternum suture firmness; in addition, the hemostatic sleeve still cannot solve the problem of sternal cutting by steel wires.
Disclosure of Invention
The invention provides a sternum suture cutting-prevention hemostatic spacer, and aims to solve the technical problem of how to provide another device capable of stopping bleeding during sternum suture and reducing steel wire cutting for the sternum, and preferably improve the convenience of sternum suture operation.
The technical problem to be solved by the invention can be realized by the following technical scheme: a sternum suture anti-cutting hemostatic gasket is characterized in that a steel wire hole for a steel wire to penetrate through is formed in the sternum suture anti-cutting hemostatic gasket, the sternum suture anti-cutting hemostatic gasket comprises a gasket base layer, a hemostatic layer and an elastic layer positioned between the gasket base layer and the hemostatic layer, and the hemostatic layer and the elastic layer can deform when the sternum suture anti-cutting hemostatic gasket is pressed; the gasket base layer is provided with a notch which enables the steel wire to be embedded into the steel wire hole from the outer side, and the hemostatic layer and the elastic layer are provided with a cutting seam which enables the steel wire to be embedded into the steel wire hole from the outer side.
During the sternal suture operation, the steel wire firstly passes through the sternum stem or the sternum body; when compression hemostasis is needed at the sternum steel wire hole, the sternum suture anti-cutting hemostasis gasket is clamped on the steel wire close to the steel wire hole, and the hemostasis layer faces towards the sternum, namely, the steel wire is embedded into the steel wire hole through the notch and the cutting seam.
When the breastbone is closed and the steel wire is screwed on the skin side of the breastbone, the two ends of the steel wire move towards the skin side, the hemostatic gasket moves and approaches along with the steel wire, the steel wire is pressed on the gasket base layer, the hemostatic layer and the elastic layer deform, and the hemostatic layer is tightly attached to the steel wire hole; thereby achieving the compression hemostasis effect and reducing the possibility of movement of the hemostatic spacer, and further reducing the possibility of sternal cutting by the steel wire.
According to the actual situation, one or two steel wire holes can be arranged on the hemostatic pad. The first scheme is as follows: the hemostatic pad is provided with a steel wire hole, and the steel wire hole is generally positioned at the center of the hemostatic pad. Scheme II: the hemostatic spacer is provided with two steel wire holes, the hemostatic spacer is usually strip-shaped, and the two steel wire holes are respectively positioned at two ends of the hemostatic spacer. When the hemostatic spacer with two steel wire holes is used, the two steel wire holes correspond to the two steel wire holes on the sternum one by one, and the steel wires penetrating out of the steel wire holes are all embedded into the steel wire holes, so that the hemostatic spacer can keep the distance between the steel wires when the steel wires are screwed, and the possibility of cutting the sternum by the steel wires is reduced; this scheme also can improve the hemostasis gasket and to the more effective and definite oppression of steel wire eye, improve hemostatic effect.
In the above sternal suture anti-cutting hemostatic spacer, thread holes are formed on both sides of the spacer base layer. When necessary, if the compression force of the hemostatic pad is insufficient, the hemostatic pad can be selected to be tightly fixed to the steel wire eye through the suture passing hole. Specifically, a thin, needled suture (e.g., 4-0 prolene) is selected that is less likely to cause tissue bleeding; the skin side of the steel wire passes through the intercostal space before being drawn to reach the visceral side of the sternum, then passes through two wire holes of the hemostatic spacer, returns to the skin side from the sternum incised edge to be converged with the other end of the wire, and is tensioned and knotted to realize the compression of the hemostatic spacer on the steel wire eye.
Compared with the prior art, the sternum suture anti-cutting hemostatic gasket buckles the steel wire and tightly adheres to the steel wire hole, so that the movement of the steel wire is effectively limited, the cutting of the steel wire on the penetrated human tissue is reduced, the bleeding possibility is reduced, and the bleeding amount is reduced.
The sternum suture cutting-proof hemostatic gasket is further pressed after the steel wires are tightened, and the elastic layer deforms, so that the fitting degree of the hemostatic layer and the sternum stem or the sternum body is improved, the expansion of a cutting seam on the hemostatic layer is avoided, the acting force uniformity of the hemostatic layer pressed on the sternum stem or the sternum body is improved, and the hemostatic effect is improved.
The sternum suture cutting-proof hemostatic gasket can be installed only when a steel wire eye bleeds or has suspected bleeding symptoms behind the sternum, but the hemostatic gasket is arranged at each steel wire eye, so that the total amount of foreign matters in a patient is reduced.
The sternum suture cutting-prevention hemostatic spacer is not influenced by the length of the hemostatic sleeve and the thickness of the hemostatic spacer, the distance between steel wire holes does not need to be accurately controlled, and the difficulty of sternum suture operation is reduced. In the process of sternal suture operation, the operation method of tensioning the steel wire by installing the sternal suture cutting-prevention hemostatic spacer is basically the same as that by not installing the sternal suture cutting-prevention hemostatic spacer, so that the operation difficulty is reduced, and the popularization of the sternal suture cutting-prevention hemostatic spacer is facilitated.
In the sternal suture anti-cutting hemostatic spacer, the spacer base layer is made of a hard material; the hemostasis layer is made of PDS; the elastic layer is made of PVA. All gasket materials can be trimmed by surgical scissors; when two adjacent hemostatic gaskets are overlapped and intersected, the overlapped parts can be cut off to enable the two adjacent hemostatic gaskets to be abutted on the same plane, and the cutting force of the steel wire on the sternum can be shared by the gaskets when the steel wire is tightened. The hemostatic spacer with two wire holes can also be cut to form two hemostatic spacers with only one wire hole.
In the above-mentioned sternal suture anti-cutting hemostatic spacer, the elastic layer and the spacer base layer are connected through the elastic layer.
In the sternal suture anti-cutting hemostatic gasket, a sleeve is arranged at the steel wire hole in a penetrating way, and an avoiding opening is arranged on the side wall of the sleeve; the positions of the avoidance openings correspond to the positions of the openings and the cutting seams; the diameter of the sleeve is consistent with that of the steel wire, and the steel wire is completely filled in the sleeve after being placed in the sleeve, so that a bleeding drainage channel is prevented from being formed.
In the above-mentioned sternal suture anti-cutting hemostatic spacer, one end of the sleeve is connected with the spacer base layer as a whole.
In the above-mentioned sternal suture anti-cutting hemostatic spacer, the inner edge of the hemostatic layer is fixedly connected with the sleeve.
In foretell sternum sutures prevents cutting hemostatic spacer, the buckle is installed to the opening department of gasket basic unit, can prevent the steel wire roll-off that is located the steel wire hole when the buckle is in the lock joint.
