Abstract

The utility model relates to a special appliance for operation on Bujia syndrome, belonging to the medical appliance. The utility model is characterized in that an expansion guide pipe is sheathed in an expansion sleeve pipe; a blood vessel support frame and a blood vessel support frame conveyor are installed in the expansion sleeve pipe; the expansion sleeve pipe forms a round pipe shape. A hole which is arranged at the center of the expansion guide pipe is communicated with a pipe joint. A blood vessel support frame thruster is the structure that the rear of a circular disc whose upper side is provided with small holes is connected with a wire propelled handle. The utility model has the advantages of low cost for the appliance, small wound for the treatment of Bujia syndrome, more safe operation, and more ideal curative effect.

Description

Cloth adds the special equipment of syndrome operative treatment

This utility model relates to a kind of special equipment that uses when a kind of medical apparatus and instruments, particularly cloth add the syndrome operative treatment.

At present, the cloth Therapeutic Method that adds syndrome has following several: 1, surgery alone treatment; (1) external following looked at barrier film excision postcava plasty straight under the ball.(2), postcava---right room artificial blood vessel is close to the road operation before the liver or behind the liver.(3), superior mesenteric vein---right shunt.(4), splenopneumopexy.Above-mentioned operation method is big to patient trauma, and danger is also big.2, interventional therapy; Narrow balloon dilatation in percutaneous puncture postcava porch and elastic support are laid.Its weak point is, foley's tube cost height, and the person is not suitable for to having the thrombosis under the barrier film.3, right room pathway postcava stenosis being dilated finger rupture of membranes art, this operation only is adapted to stenosis being dilated, and can't place the vessel support frame simultaneously in the art, postoperative recurrence rate height.

The purpose of this utility model is at aforementioned the deficiencies in the prior art, mounts to put and treats cloth and add the syndrome surgery instrument and disclose the expansion of a kind of right room pathway postcava and vessel support.Improve present Therapeutic Method to reach, avoid the deficiency of the big shortcoming of wound and other Therapeutic Method, make that cloth is added the Therapeutic Method of syndrome is simple and safe and effective.

This utility model realizes as follows, and it is as follows that cloth adds the organization plan of special equipment of syndrome operative treatment: a, suit dilating catheter 2 in expanded casing 1.B, can pack into after the dilating catheter in the expanded casing 12 taken out vessel support frame 3 and vessel support frame carrier 4.C, expanded casing 1 are made the pipe shape by spring and anti-folding plastics.D, dilating catheter 2 tops are bullet-shaped, and tail end is the cap shape, and there are two pipe joints 5 both sides, have a hole 6 to communicate with pipe joint 5 at the center of dilating catheter 2.E, vessel support frame 3 are metal cage shape cylinder and leaving certain gaps uncovered by the economic plan.F, vessel support frame propeller 4 are that a disk 7 backs connect the structure that steel wire advances handle 8, on the disk 7 aperture are arranged.

Good effect of the present utility model is: this cover operating theater instruments is cheap, adds syndrome with the method treatment cloth, can avoid the big shortcoming of wound of existing therapeutic method of surgery, also can remedy the deficiency of some art formulas.Make operation safer, curative effect is even more ideal.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the user mode figure of row when executing the intravascular stent implantation.

Fig. 3 is an intravascular stent structure chart of the present utility model.

Fig. 4 is the structure chart of propelling handle of the present utility model.

Wherein:

1, expanded casing 2, dilating catheter 3, vessel support frame

4, vessel support frame carrier 5, pipe joint 6, conduction hole

Below in conjunction with accompanying drawing this utility model is described in further detail:

Shown in Fig. 1,2,3 and 4.It is as follows that cloth adds the organization plan of special equipment of syndrome operative treatment: a, suit dilating catheter 2 in expanded casing 1.B, can pack into after the dilating catheter in the expanded casing 12 taken out vessel support frame 3 and vessel support frame carrier 4.C, expanded casing 1 are made the pipe shape by spring and anti-folding plastics.Flexibility is big, its thickness of pipe wall 2mm, and intracavity is smooth, and length is 300--370mm, and its external diameter is 16--30mm, can every poor 2mm be a model, supplies to insert the usefulness that dilating catheter 2 expansion backs are drawn thrombosis and passed through inner chamber delivery of vascular bracing frame 3.D, dilating catheter 2 tops are that bullet-shaped tail end is the cap shape, and there are two pipe joints 5 both sides, for the usefulness that splashes into heparin saline and pressure measurement in the art.It is that the hole 6 of 3mm communicates with pipe joint 5 that one diameter is arranged at the center of dilating catheter 2, and hole 6 is used for rupture of membranes in case of necessity for inserting the rupture of membranes steel wires.The external diameter of dilating catheter 2 and the internal diameter of expanded casing 1 be supporting to become various models.Diameter is from 12--26mm.E, vessel support frame 3 are metal cage shape cylinder and leaving certain gaps uncovered by the economic plan, its length is divided into 30,40, and 50, four kinds of models of 60mm, its external diameter 11--27mm, model of every 2mm, totally 9 kinds, play a supportive role for being transported to the narrow blood vessel place after the expansion, cage shape and breach do not influence hepatic vein and reflux, and breach flicks after being convenient to send into voluntarily, increase the width of support blood vessels.F, vessel support frame propeller 4 are that a disk 7 back connects the structures that steel wires advance handles 8, and 4 apertures are arranged on the disk 7, be convenient to blood when advancing from then on orifice flow go out, the external diameter of disk 7 with the internal diameter and the vessel support frame external diameter of supporting expanded casing 1 consistent.The use operation sequence of this apparatus is as follows: 1, preceding median incision advances breast, and after the rip cutting pericardium exposed right room, right room purse string suture cut, and inserts expanded casing 1 and dilating catheter 2 and reaches postcava every epimere, be i.e. top, IVC stenosis place.The top of the top of expanded casing 1 and dilating catheter 2 maintains an equal level during intubate, props up stenosis degree of being with the top of expanded casing 1.2, fixed sleeving continues to advance dilating catheter 2, expansion stenosis postcava.3, after dilating catheter 2 enters stenosis, push ahead, make expanded casing 1 enter stenosis together with expanded casing 1.4, extract dilating catheter 2 out.5, vessel support frame 3 is packed in the expanded casing 1, send into the top of expanded casing 1 with vessel support frame carrier 4.6, withdraw from expanded casing 2 and vessel support frame carrier 4.7, the right room of ligation pocket closes breast, and operation is promptly accused and finished.
