Description

New disposable sheath pipe

Technical field:

This utility model relates to a kind of new disposable sheath pipe, belongs to a kind of medical apparatus and instruments, particularly a kind of invasive diagnosis such as cardiac catheter visualization and crown aortic sac plasty and treatment assistive device of being used for.

Background technology:

Interventional technique grew up in the later stage seventies, it is under medical imaging (X line, ultrasonic, CT, MRI) guiding, by the percutaneous puncture approach or by the original duct of human body, special conduit or apparatus are inserted to diseased region diagnose radiography and treatment or gather tissue, carry out cytology, bacteriology and biochemical analysis.In the operation process of these diagnosis or treatment, because vascular puncture, and conduit and apparatus are in endovascular frequent turnover, the capital causes bigger damage for skin and blood vessel, blood loss is big, when carrying out the operation of the type, earlier the sheath pipe is inserted blood vessel, diagnosis of using in the operation or catheter for treating are by the sheath pipe in the intravasation then.Therefore use the sheath pipe just can lower the damage of blood vessel, prevent loss of blood, conduit and relevant appliance be the focus of intravasation easily, thereby can shorten the time of whole surgery, alleviates patient's misery, has improved the success rate of operation.Owing to structural reason, but it is not fine still causing injury, particularly haemostatic effect to blood vessel easily to existing sheath pipe usually.Existing in addition sheath pipe has no idea to be easy to generate displacement in good fixed position, can influence the carrying out of operation to a certain extent.

Technology contents:

It is a kind of simple in structure that the purpose of this utility model is to provide, and haemostatic effect is good, and fixed-site is good, and is easy to operate, and be difficult for the new disposable sheath pipe of injured blood vessel.

The purpose of this utility model is achieved in that

A kind of new disposable sheath pipe, it comprises a sleeve pipe, a connector that is connected a telescopic end, the other rotary valve of managing and being connected on the other end of other pipe that is connected on the other end of connector also is provided with a haemostatic valve on described connector; On described sleeve pipe, be provided with a suture seat.Described haemostatic valve is two enclosuring structures.Outside described haemostatic valve, be provided with a bonnet that is nested with haemostatic valve.On the tube wall at described two ends at other pipe, be provided with labelling neck ring.Described telescopic end is tapered, and tapering is: 1: 8.At described suture seat is movable suture seat, is provided with the double-vane that is used to sew up threading on described suture seat.Become 60 ° to be connected and to communicate at described and described sleeve pipe.Described other pipe is transparent tube.On the neck ring that is located on the tube wall of described other pipe two ends, be provided with color mark.

This utility model is simple and reasonable for structure, can effectively reduce blood loss in the operation process, lowers the damage of blood vessel, makes that utensil turnover blood vessel such as conduit is easy.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model

Accompanying drawing 2 is a haemostatic valve partial structurtes sketch map of the present utility model.

Accompanying drawing 3 is a suture seat sketch map of the present utility model.

Accompanying drawing 4 is a tube ends sketch map of the present utility model.

The specific embodiment:

Shown in Figure 1, comprise 2, one bonnets 3 that coating haemostatic valve 2 of 1, one haemostatic valve of a sleeve pipe, by a connector 4 haemostatic valve 2 is connected with sleeve pipe 1 and communicates, suture seat 5 cover are stuck on the junction of sleeve pipe 1 and connector 4.Transparent other pipe 6 is connected with the side mouth of connector 4, and the other end that rotary valve 7 is embedded in other pipe 6 connects, two neck rings 8 respectively cover be stuck in other pipe 6 and connector 4 and with the junction of rotary valve 7.

The internal layer of sleeve pipe 1 is by high density polyethylene (HDPE), skin is formed by the double-deck compacting of low density polyethylene (LDPE), hardness and to turn round control power suitable, end is processed into taper, when vasodilation pipe or other conduit insertion sleeve pipe 1, can be excessive between them for " zero ", guarantee that sleeve pipe 1 imports blood vessel easily, and be difficult for causing the damage of blood vessel and skin; The propelling of various conduits in sleeve pipe 1 of using in convergent divergent channel and the intervene operation is also very smooth and easy.And sleeve pipe 1 design has the specification of different sizes and length, to be fit to different patient and operative sites.

The material of haemostatic valve 2 is a silicones, its elasticity and nerve are very strong, even the various conduits that use in convergent divergent channel and the intervene operation repeat repeatedly to insert haemostatic valve 2 and enter sleeve pipe 1, after perhaps conduit has been drawn out of, haemostatic valve 2 still can complete closure, can effectively prevent the leakage of blood.3 of bonnets firmly are wrapped in haemostatic valve 2, only expose an aperture on the top, so that the entering of conduit.Suture seat 5 is made by gum elastic, and cover is stuck on the junction of connector 4 and sleeve pipe 1, and it can do suitable rotation.On described suture seat 5, be provided with the double-vane 11 that is used to sew up threading, after sleeve pipe has entered blood vessel, pass line hole on the double-vane 11 with stitching thread, facilitate like this it temporarily is sewn on the skin, make whole sheath guard system can be not long or the extremity of patient in operation process are movable and blood vessel is caused damage because of the intervene operation time.

Other guard system comprises that other pipe 6, rotary valve 7 and neck encircle 8 and form, and main effect is the air in the punching press sleeve pipe, and injection anticoagulant medicinal liquid after the operation.

Operating process is as follows:

Utilization is furnished with heparinized saline or suitable isosmotic solution is pressed the air of going out in the sheath pipe through rotary valve.Vessel dilator is inserted the sheath pipe by haemostatic valve.Firmly vasodilation pipe bulge loop is screwed into haemostatic valve, distend the blood vessels pass pipe and haemostatic valve and sleeve pipe firmly are nested together.Dash with heparinized saline or suitable isosmotic solution pressure.Puncture needle thrusts blood vessel, then needle guard is pushed in the blood vessel.Hold syringe needle, the flexible end of seal wire is penetrated syringe needle and insert in the blood vessel.Grip seal wire, extract syringe needle and firmly pin the insertion position, till sleeve pipe/vasodilation pipe unit inserts blood vessel.Sleeve pipe/vasodilation pipe unit is passed seal wire, holding sleeve pipe near the skin place in order to avoid crooked.To install with the action of rotation distortion and to push in the blood vessel by subcutaneous tissue.For avoiding damaging telescopic tip, before putting into blood vessel, sleeve pipe/vasodilation pipe unit please don't take out the vasodilation pipe.Disengage vasodilation pipe bulge loop from sheath pipe hemostasis bonnet, can be with vasodilation pipe removal from the sheath pipe.Remove seal wire and dilator.Because the haemostatic valve on the sheath pipe, blood just can not leak into external.From side pipe suction, to get rid of residual air.After suction and pressure are dashed, can manage injecting heparin solution to the side, in case thrombosis.Take longlyer as this intervene operation, the suture seat of sheath pipe can be sewn near the skin the puncture orifice.
