Abstract
The utility model relates to a medical appliance, particularly to a small blood vessel spreader. The small blood vessel spreader comprises a support tube and an elastic stainless steel plate, wherein an inclined plane is arranged at the front end, namely a working end, of the support tube; a through hole is arranged at the position which is roughly at the middle part of the support tube; two bucklings in opposite directions are arranged at the positions which are roughly at the middle part of the elastic stainless steel plate; a straight line segment part between the two bucklings is in the through hole; the rear end of the elastic stainless steel plate is fixedly connected with the rear part of the support tube; the front end of the elastic stainless steel plate is flush with the front end of the support tube; a distance is formed between the two bucklings and the support tube; the front part of the elastic stainless steel plate is provided with a free section; the part from the second buckling of the elastic stainless steel plate to the front end and the support tube are gradually attached; the first buckling of the elastic stainless steel plate is at the side of the inclined plane, and the second buckling of the elastic stainless steel plate is at the opposite side of the inclined plane. The small blood vessel spreader is mainly applied to a coronary artery bypass operation of cardiac surgery to grasp and spread a bridge vessel. The surgical operation is facilitated, and the success rate of the operation is improved.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of little blood vessel dilator; Be mainly used in the department of cardiac surgery bypass operation of coronary artery, the bridge blood vessel is grasped and struts.
Background technology
In the department of cardiac surgery bypass operation of coronary artery, not having at present special-purpose facility apparatus, do not have the bridge blood vessel to grasp and device for spreading, all is that blood vessel is placed on the gauze, grasps anastomosis of blood vessel then with tweezers, and operation technique is very inconvenient.
The utility model content
The purpose of this utility model be to provide a kind of simple in structure, make little blood vessel dilator easy, easy to use, in effective solution department of cardiac surgery bypass operation of coronary artery, do not have the technical problem that grasps and strut the bridge vascular devices; Use this utility model to be convenient to operation technique, save operating time.
This utility model realizes that the technical scheme that above-mentioned purpose is taked is: a kind of little blood vessel dilator 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, and elastic stainless steel sheet front end and stay pipe front end flush are provided with distance between bending of two places and the stay pipe; Elastic stainless steel sheet front portion is free section, and elastic stainless steel sheet second is bent to progressive applying between fore-end and the stay pipe.
First bending of elastic stainless steel sheet is positioned at the inclined-plane side, and 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 first bending place, the front end of elastic stainless steel sheet breaks away from stay pipe; The stay pipe front end is inserted in the bridge blood vessel, blood vessel is strutted, finger unclamps the elastic stainless steel sheet, leans on the elasticity of elastic stainless steel sheet; Vascular clamp is held in little blood vessel dilator front end, and like this, the bridge blood vessel is strutted and is fixed on the chamfered portion of stay pipe front end; Again little blood vessel dilator is moved nearly arteria coronaria anastomotic stoma, wear seam, be convenient to vascular anastomosis from the stay pipe incline position.
This utility model 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 patient's rehabilitation.Have and make easily, 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.This utility model can be made into disposable products or reusable product as required.
Description of drawings
Fig. 1 is the structural representation of little blood vessel dilator.
Among the figure: 1-stay pipe, 101-inclined-plane, 102-through hole, 2-elastic stainless steel sheet, 201-the first bending, 202-the second bending, 3-screw, the distance of L1-through hole to front end, the distance of L0-inclined-plane section start to front end.
The specific embodiment
As shown in the figure: a kind of little blood vessel dilator, 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, and elastic stainless steel sheet 2 front ends and stay pipe 1 front end flush are provided with distance between bending of two places and the stay pipe 1; Elastic stainless steel sheet 2 front portions are free sections, and second bending 202 of elastic stainless steel sheet 2 is to progressive applying between fore-end and the stay pipe 1.
The length of stay pipe 1 is 135 millimeters; The distance L 1 of through hole 102 to front end is 60 millimeters, and the distance L 0 of inclined-plane section start to front end is 26 millimeters.
Stainless steel tube that stay pipe 1 usefulness diameter is 6 millimeters or plastic tube are made.
