Abstract
The utility model relates to a core bipolar femoral vein spile for a thoracoscopic cardiac surgery, comprising a spile body with ahollow inner cavity and a puncturing guide core arranged at the inner cavity of the splie body and provided with a tip. A longer front segment of the splile body has steel wire reinforcement; and the shorter rear segment of the spile body has a thicker spile wall than the front segment. The femoral vein spile adopts the design with a thin front part and a wide rear part, the design is in line with the ergonomics principle, the front segment adopts thin wall large cavity steel wire reinforcement design, the high flow of blood can be ensured, and the spile body can not be sunken in the case of negative pressure.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of thoracoscope operation on heart belt carcass bipolar (two-chamber) femoral venous catheter.
Background technology
Along with the continuous development of cardiac operation is perfect, so far, nearly all congenital heart disease, coronary heart disease, valvular heart disease can both be performed the operation down by traditional extracorporeal circulation and be obtained treatment.Simultaneously,, except pursuing good surgical outcome, also wish operation risk is reduced to bottom line in the industry, and will consider the more aesthetic problem of back wound along with the continuous prosperity of medical science and technology.Department of cardiac surgery is also the same with other field, and developing to Wicresoft's direction has also become a kind of inexorable trend.As the indispensable apparatus of minimally invasive cardiac surgery, how to develop a kind of perfect belt carcass femoral venous catheter, in the major function that realizes possessing in operation with oxygenate outside the blood lead body human body that reinjects after good, have the reasonability of self structure concurrently, be important research direction in the industry always.
The utility model content
The purpose of this utility model provides a kind of thoracoscope operation on heart with the bipolar femoral venous catheter of belt carcass, to solve the aforementioned problems in the prior.
In order to achieve the above object, the technical solution of the utility model proposes a kind of thoracoscope operation on heart bipolar femoral venous catheter of belt carcass, comprise intubate body with hollow cavity, and be arranged at described intubate chamber body and have most advanced and sophisticated puncture and lead core, the long leading portion of described intubate body has steel wire to be reinforced, and the short back segment of described intubate body then has the tube wall thicker than described leading portion.
Above-mentioned thoracoscope operation on heart is with in the bipolar femoral venous catheter, and the leading portion of described intubate body is being led the position at core tip and is being respectively equipped with several side openings in the centre position of described leading portion near described puncture.
The femoral venous catheter that technical solutions of the utility model provide has following beneficial effect: the intubate body adopts front fine and rear thick design, meets the human engineering principle; The leading portion of intubate body adopts the big chamber of thin-walled steel wire Design of Reinforcement, can guarantee the high flow capacity of blood, can not make the body collapsing under the situation of negative pressure again.
Description of drawings
Fig. 1 is the example structure figure of this utility model thoracoscope operation on heart with the bipolar femoral venous catheter of belt carcass.
The specific embodiment
Following examples are used to illustrate this utility model, but are not used for limiting scope of the present utility model.
Fig. 1 is the example structure figure of this utility model thoracoscope operation on heart with bipolar femoral venous catheter, as shown in the figure, the bipolar femoral venous catheter 20 of the belt carcass of present embodiment, comprise intubate body 21, and be arranged at the inner chamber 211 of intubate body 21 and have most advanced and sophisticated 221 puncture and lead core 22 (dotted portion is represented to be positioned within the intubate body 21 among the figure) with hollow cavity 211.Wherein, puncture is led core 22 and is adopted flexible material, can easily intubate body 21 be led the into very dark position of blood vessel, and can support that intubate body 21 inserts again not can injured blood vessel; 21 of intubate bodies adopt the overlength design, its long leading portion 212 has steel wire and reinforces, and short back segment 213 has the tube wall thicker than leading portion 212, front fine and rear thick herein design, not only meet the human engineering principle, and the big chamber of the thin-walled of its leading portion steel wire Design of Reinforcement, can guarantee the high flow capacity of blood can under the situation of negative pressure, not make the body collapsing again.In addition, the leading portion 212 of intubate body 21 is being led the head position at core 21 tips 221 and is being respectively equipped with several side openings 214, the fully blood in drain epicoele and postcava and orientation in the centre position of leading portion 212 near puncture.
In sum, the femoral venous catheter that technical solutions of the utility model provide has following beneficial effect: puncture is led core and is adopted flexible material, can easily intubate be led the into very dark position of blood vessel, and can support that the intubate body inserts again not can injured blood vessel; The intubate body of overlength design can satisfy the patient of various heights; Intubate adopts front fine and rear thick design, meets the human engineering principle; The leading portion of intubate adopts the big chamber of thin-walled steel wire Design of Reinforcement, can guarantee the high flow capacity of blood, can not make the body collapsing under the situation of negative pressure again; The body of overlength can satisfy the patient of various heights; And the design of the side opening in intubate body head end and leading portion centre position, fully drain epicoele and inferior caval blood
More than be preferred forms of the present utility model, according to the disclosed content of this utility model, those of ordinary skill in the art can expect some identical, replacement schemes apparently, all should fall into the scope of this utility model protection.
