Description

Suture fixation device for heart valve replacement surgery

technical field

The utility model belongs to the technical field of medical operation aids, and is a surgical suture fixing device used for open valve replacement in cardiac surgery to assist valve suturing, in particular to a heart valve replacement surgical suture fixing device.

Background technique

Suturing is a basic operation in surgery and one of the important steps in surgery. In surgical operations, especially open valve replacement in cardiac surgery, there are multiple double-needle suture pull marks, interrupted sutures, and uniform knotting of indwelling tail lines. Due to the small and deep field of view in the operation area and the limited space around the valve, when there are multiple double-ended and tail lines, the troubles of intertwined and disordered sutures often occur, resulting in clutter in the operation area, wrong stitches and knots. Needle stick injuries and other phenomena that seriously affect the operation process and quality occur. In the past, the method used in this field to deal with the above problems was to use leather tube clamps or mosquito clamps to clamp the ends of the sutures to fix the surgical sutures, but this method has the following defects: 1. the clamped lines of the vascular clamps will meet the suture ②The weight of the vascular forceps itself can form a certain pulling force, which makes it difficult to grasp the tightness of the sutures, resulting in tissue tearing; ③It is difficult to distinguish pairs of sutures due to too many sutures, which affects knotting , When there are many sewing needles, the pliers are not enough to use; 5. When more double-needle sutures are piled up, it is easy to stab the operator; 6. When more pliers fix the sutures, the operation area will be messy and unclean.

Utility model content

The purpose of this utility model is to solve the defects of many sutures and difficult fixation in current clinical surgical operations, so as to make better use of surgical techniques, ensure that the surgical field is clean and tidy, avoid intraoperative suturing needle injuries, and shorten the operation time.

The technical solution adopted in order to realize the purpose of the above invention is: a surgical suture fixing device for heart valve replacement. The provided surgical suture fixing device consists of an upper fixing ring, a lower fixing ring and a fixing rod.

A part of the upper fixed ring forms an integral body with the movable connecting rod and is fixed on the fixed rod by an elastic steel bar; the elastic steel bar adjusts the height of the upper fixed ring by adjusting the fixer; the upper fixed ring Linked with elastic steel bars by rectangular snap link device.

The upper fixing ring is evenly divided into three parts, and each part is connected to each other by a buckle link device to form a ring shape, and the buckle is rectangular.

20 protruding trapezoidal clamps are uniformly arranged on the upper fixing ring, and the clamps are marked with Arabic numerals and English letters.

The clamp has a trapezoidal structure, and a curved gap is left in the middle. The two sides of the gap are respectively a rubber surface and a PVC hard material surface, and the gap gradually narrows from the outside to the inside.

The two rings of the lower suture fixing device and the movable connecting rod form an integral body, and are connected with the rigid connecting rod through a pivot joint, and the rigid connecting rod is fixed on the fixing rod through an adjusting fixer. The lower fixing ring is arc-shaped in two parts.

20 protruding trapezoidal wire clips are evenly arranged on the lower fixing ring, and the wire clips are marked with Arabic numerals and English letters corresponding to the wire clips in the upper fixing ring. The structure of the clamp is the same as that of the upper layer.

The fixing rod is cylindrical, and the lower end is integrated with the card slot. The card slot is a rectangular opening, and the upper end is provided with a fixing knob.

Compared with the prior art, the utility model has the following advantages: ①Simple structure, convenient operation, low cost, no confusion of sutures during the operation, obvious simplification of the operation process of the operation, reduction of operation errors, and improvement of operation efficiency; ②The selected material is light in weight, easy to clean, and can be sterilized at low temperature; ③It is easy to fix due to its weight during use, which can reduce the pulling on tissue blood vessels and save manpower; ④The upper and lower double-layer settings make each pair of sutures orderly and symmetrical , not easy to confuse, easy to tie; ⑤It is clear at a glance when calculating the number of stitches; It has good elasticity, so as to ensure that the suture is in a straightened state without causing tearing of the sutured tissue.

Detailed ways

The content of the present utility model will be further described below in conjunction with the accompanying drawings.

Fig. 1 is a schematic diagram of an overall view of the present utility model. Including the upper fixed ring, the lower fixed ring and the side L-shaped fixed bracket; the upper fixed ring and the lower fixed ring are respectively fixed on the bracket rod 9 by adjusting the fixers 7, 8 and 7.1, 8.1, and can be adjusted up and down at will; the fixed bracket rod 9 It is fixed on the sternal spreader after the operation starts by means of fixing devices 10 and 11.

Fig. 2 is a specific schematic diagram of the lower fixing ring of the present invention. The suture fixing ring is mainly composed of two curved parts made of PVC material with a long axis of 25-35cm. There are 10 thread clips uniformly arranged on the inner sides of the two curved parts. The wires are sequentially clamped in the wire clamp gap, and the two arc-shaped parts of the fixing ring can be expanded to both sides at will through the movable link device 4.1 according to the size of the surgical incision and the degree of exposure of the surgical field. 8 to adjust the height of the two arc-shaped fixing rings at will, so that it can better fit the exposed field of view of the operation area, which is convenient for suture clamping and fixing, and does not affect the operator's field of vision.

Fig. 3 is a specific schematic diagram of the upper fixed ring of the utility model. The fixing ring is a circular structure made of PVC material. It can be disassembled into three fan-shaped parts through a snap-fit connection device. A plurality of protruding wire clips are evenly arranged on the outside of each part, and a total of 20 can be clamped. When the valve ring sutures are all sutured and the artificial valve is started to be sutured, the tail of the lower fixing ring can be removed in turn and continue to sew to the valve, and then the tail of the suture can be fixed to the upper fixing ring Corresponding wire clips, after all the sutures are properly fixed, the upper layer of the fixed ring is divided into three parts, that is, the tail wire is divided into three parts, so as to facilitate pushing the artificial valve into the annulus with uniform force. After the joint is tight, the assistant can hand over the orderly arranged tail threads on the three parts of the fixed ring to the surgeon for knotting, thus avoiding the confusion of the sutures and the wrong stitches caused by the assistant holding a large number of pliers with bare hands. Knots, needles stabbing surgical personnel, etc., make the whole suturing process programmed, greatly improving the efficiency of surgery.

Fig. 4 is a specific schematic diagram of the rectangular buckle connection device of the present invention. After the artificial valve is sutured, the device can be used to split the upper fixed ring into three fan-shaped parts, and the tail wire is divided into three strands, so that the artificial valve can be gently pushed into the annulus by the uniform force of the three strands.

Fig. 5 is a specific schematic diagram of the wire clip of the present invention. The cable clamp is in trapezoidal structure, with a curved gap left in the middle. The two sides of the gap are the rubber surface and the PVC hard material surface respectively, and the gap gradually narrows from the outside to the inside. When suturing, the tail ends of the sutures can be respectively clamped in the clamping gaps of the corresponding clamps in turn, and the sutures are tightly fixed in it by the friction force of the rubber material and the pressure on both sides of the gaps.
