AI Technical Summary
Traditional inferior vena cava clamping is difficult to perform in thoracoscopic-assisted inferior vena cava surgery, and can easily lead to inferior vena cava rupture and massive bleeding, affecting the surgical field and operation.
A minimally invasive inferior vena cava dressing device was designed, which adopts a curved structure made of alloy material. The handle, rod and head are integrally molded. The rod has a curvature of 145 degrees, the head is U-shaped, and the suture hole is used for suture to pass through, so as to achieve 180-degree operation.
It improves operational flexibility, reduces the risk of inferior vena cava rupture, shortens operation time, and lowers the probability of complications.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to thoracoscope heart operation technical field especially, a kind of minimally invasive inferior vena cava overpass device. BACKGROUND
[0002] Thoracoscope assisted extracorporeal circulation heart operation, due to narrow surgical field, limited space, the inferior vena cava overpass forceps of traditional thoracotomy heart direct vision operation is difficult to operate in this operation, and it is easy to cause iatrogenic rupture of inferior vena cava, cause massive hemorrhage to affect surgical field and operation. Therefore the utility model proposes a kind of minimally invasive inferior vena cava overpass device here. SUMMARY
[0003] The utility model aims at solving the defects in prior art, and proposes a kind of minimally invasive inferior vena cava overpass device.
[0004] In order to realize the above-mentioned purpose, the utility model adopts the following technical scheme:
[0005] A kind of minimally invasive inferior vena cava overpass device, including handle, the front end of handle is fixed with stem portion, stem portion is arc curved, and the front end of stem portion is fixed with head, head is U-shaped curved, one end of head is fixed with the front end of stem portion, the other end of head is equipped with wire passing hole, wire passing hole is used to pass through surgical suture line.
[0006] Further, the handle, stem portion and head are integrally formed structure, which are bent from alloy material.
[0007] Compared with prior art, the utility model has the beneficial effects that:
[0008] Traditional right-angle hemostatic forceps, when passing through inferior vena cava, the angle can only reach 90 degrees, repeated operation, because there is surgical field blind area, it is easy to damage inferior vena cava and cause fatal massive hemorrhage, and using the overpass device, the curvature can reach 180 degrees, and it is not easy to cause heart injury;The utility model can quickly complete inferior vena cava overpass loop operation in thoracoscope heart operation, and is flexible and convenient to operate, and can reduce the rupture of inferior vena cava caused by operation. BRIEF DESCRIPTION OF DRAWINGS
[0009] The accompanying drawings are included to provide a further understanding of the utility model, and constitute part of the specification, and are used together with the embodiments of the utility model to explain the utility model, and do not constitute the limitation to the utility model.
[0010] Fig. 1 It is front view of the utility model;
[0011] Fig. 2 It is axial view of the utility model;
[0012] Fig. 3 The drawing shows the opening of the wire hole in the head part.
[0013] In the drawing: 1 handle, 2 rod part, 3 head part, 4 wire hole. DETAILED DESCRIPTION
[0014] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model;
[0015] Refer to Figs. 1-3 A minimally invasive inferior vena cava passing belt device, comprising a handle 1, the handle 1 is in a long annular structure, and can be used for holding and performing hooking and pulling operations.
[0016] The handle 1 is fixed with a rod part 2 at the front end, and the rod part 2 is in an arc-shaped curved shape; in the embodiment, the circular arc angle of the rod part 2 is 145°.
[0017] The rod part 2 is fixed with a head part 3 at the front end, and the head part 3 is in a U-shaped curved shape; one end of the head part 3 is fixed with the front end of the rod part 2, and the other end of the head part 3 is provided with a wire hole 4, and the wire hole 4 is used for passing through a surgical suture. The handle 1, the rod part 2 and the head part 3 are in an integral molding structure, and are curved from an alloy material.
[0018] The conventional right-angle hemostatic forceps can only reach 90 degrees when passing through the inferior vena cava, repeated operations are needed, and the inferior vena cava is easily damaged to cause fatal hemorrhage due to the existence of the operation field blind area. By using the utility model, the bending degree can reach 180 degrees, and heart damage is not easy to cause;
[0019] Compared with the conventional passing belt forceps, the operation time of the utility model is shortened, the efficiency is obviously improved, and the probability of complications is effectively reduced.
[0020] The utility model can quickly complete the inferior vena cava passing belt loop operation in the thoracoscope heart surgery, is flexible and convenient in operation, and can reduce the inferior vena cava rupture caused by operation.
