Abstract
The invention relates to a medical instrument, in particular to a small vessel distraction device. The small vessel distraction device comprises a supporting tube and an elastic stainless steel sheet; an inclined surface is arranged at the front end, i.e. working surface of the supporting tube, and a through hole is arranged in an approximate middle position of the supporting tube; two kinks in the opposite directions are arranged in the approximate middle position of the elastic stainless steel sheet; a straight line segment part between the two kinks is positioned in the through hole; the back end of the elastic stainless steel sheet is fixedly connected with the rear of the supporting pipe; the front end of the elastic stainless steel sheet is flush with the front end of the supporting tube; distances exits between the two kinks and the supporting tube; the front part of the elastic stainless steel sheet is a free segment; and the part from the second kink of the elastic stainless steel sheet to the front end is gradually glued to the supporting tube. The first kink of the elastic stainless steel sheet is positioned at the side of the inclined surface; and the second kink of the elastic stainless steel sheet is positioned at the opposite side of the inclined surface. The small vessel distraction device is mainly applied to the coronary artery bypass graft in the department of cardiac surgery, is used for grasping and opening saphenous vein bypass graft, is convenient for surgery procedures and increases the success rate of operation.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, specifically a kind of little vascular opening device; Be mainly used in the department of cardiac surgery bypass operation of coronary artery, the bridge blood vessel is grasped and struts.
Background technology
There is no at present special-purpose facility apparatus in the department of cardiac surgery bypass operation of coronary artery, do not have the bridge blood vessel to grasp and device for spreading, is all that blood vessel is placed on gauze, grasps then anastomosis of blood vessel with tweezers, and operation technique is very inconvenient.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, make little vascular opening device easy, easy to use, in effective solution department of cardiac surgery bypass operation of coronary artery, without the technical problem that grasps and strut the bridge vascular devices; Use the present invention to be convenient to operation technique, save operating time.
The present invention realizes that the technical scheme that above-mentioned purpose is taked is: a kind of little vascular opening device is characterized in that:
It comprises stay pipe and elastic stainless steel sheet; The stay pipe front end is that the working end is provided with the inclined-plane, and stay pipe approximate mid-section position is provided with through hole; Elastic stainless steel sheet approximate mid-section position is provided with the reciprocal bending in two places, straightway between the bending of two places partly is positioned at through hole, the rear end of elastic stainless steel sheet is fixedly connected with the stay pipe rear portion, elastic stainless steel sheet front end is mutually concordant with the stay pipe front end, be provided with distance between the bending of two places and stay pipe, elastic stainless steel sheet front portion is free segment, and elastic stainless steel sheet second is bent to progressive applying between fore-end and stay pipe.
The first bending of elastic stainless steel sheet is positioned at the inclined-plane side, and the second bending of elastic stainless steel sheet is positioned at the inclined-plane opposite side.
During use, the rear portion of hand-held supports pipe, finger pressure elastic stainless steel sheet the first bending place, the front end of elastic stainless steel sheet breaks away from stay pipe, and the stay pipe front end is inserted in the bridge blood vessel, with vascular opening, finger unclamps the elastic stainless steel sheet, elasticity by the elastic stainless steel sheet is held in little vascular opening device front end with vascular clamp, like this, the bridge blood vessel is strutted and is fixed on the chamfered portion of stay pipe front end, again little vascular opening device is shifted near the arteria coronaria anastomotic stoma, wear seam from the stay pipe incline position, be convenient to vascular anastomosis.
The present invention can effectively grasp and strut the bridge blood vessel, is convenient to operation technique, improves success rate of operation, shortens operating time, is beneficial to Rehabilitation.Have and make easily, the characteristics such as easy to use are mainly used in the department of cardiac surgery bypass operation of coronary artery, the grasping and strutting of bridge blood vessel.The present invention can be made into disposable products or reusable product as required.
Description of drawings
Fig. 1 is the structural representation of little vascular opening device.
In figure: 1-stay pipe, 101-inclined-plane, 102-through hole, 2-elastic stainless steel sheet, the 201-the first bending, the 202-the second bending, 3-screw, L1-through hole are to the distance of front end, and L0-inclined-plane section start is to the distance of front end.
The specific embodiment
As shown in the figure: a kind of little vascular opening device, it comprises stay pipe 1 and elastic stainless steel sheet 2; Stay pipe 1 front end is that the working end is provided with inclined-plane 101, and stay pipe 1 approximate mid-section position is provided with through hole 102; Elastic stainless steel sheet 2 approximate mid-section positions are provided with the reciprocal bending in two places, straightway between the bending of two places partly is positioned at through hole 102, the rear end of elastic stainless steel sheet 2 is fixedly connected on stay pipe 1 rear portion by screw 3, elastic stainless steel sheet 2 front ends are mutually concordant with stay pipe 1 front end, be provided with distance between the bending of two places and stay pipe 1, elastic stainless steel sheet 2 front portions are free segments, and the second bending 202 of elastic stainless steel sheet 2 is to progressive applying between fore-end and stay pipe 1.
The first bending 201 of elastic stainless steel sheet 2 is positioned at inclined-plane 101 sides, and the second bending 202 of elastic stainless steel sheet 2 is positioned at inclined-plane 101 opposite sides.
The length of stay pipe 1 is 135 millimeters; Through hole 102 is 60 millimeters to the distance L 1 of front end, and inclined-plane section start to the distance L 0 of front end is 26 millimeters.
The stainless steel tube that stay pipe 1 use diameter is 6 millimeters or plastic tube are made.
