Abstract
The present utility model discloses a head bending shape controllable guiding catheter for medical application, the head part of the guiding catheter is inlaid with a metal ring, the metal ring is connected with one end of a steel wire for controlling the bending shape of the head part, the other end of the steel wire extends out of the guiding catheter, when the steel wire is drawn by outside force, and the head part of the guiding catheter can be bended to form a desired shape through drawing the metal ring tight. According to the utility model, in an operation, a doctor dose not need to replace different guiding catheters only by using the guiding catheter of the utility model by controlling the shape of the head part of the guiding catheter through a handle at the near-end of the guiding catheter, therefore, the operation time can be reduced and patient pain can also be reduced. For some patients, the shape of the inlet of a coronary artery does not conform to a conventional shape, which makes the finding of the inlet of the coronary artery by the doctor more difficult. By using the guiding catheter of the utility model, the shape of the head part can be adjusted at any time, which makes the operation of doctors more convenient.
Description
Technical field
This utility model relates to a kind of medical guiding catheter, specifically is meant a kind of medical guiding catheter of head-bent controllable shapes.
Background technology
Guiding catheter (Guiding Catheter) and angiography catheter (Diagnostic Catheter) are requisite auxiliary facilities in the intervene operation.When the coronary artery intervene operation, the doctor at first broadcasts seal wire the coronary artery in pathological changes, again guiding catheter is pushed to the coronary artery porch along seal wire, after carrying out radiography, also determine diseased region, foley's tube or stent pushing to diseased region, and are carried out sacculus or support expansion operation.Because vascular bending is changeable in the body, guiding catheter can play the effect of guiding and protective cradle, can make the doctor rapidly with sacculus or stent pushing to diseased region.Because each patient's coronary artery entrance shape difference, the far-end of guiding catheter also will be made difformity, that is to say that the product type of guiding catheter is no less than tens kinds.Each intervene operation, the doctor not only must use guiding catheter, sometimes also will be with the guiding catheter of using several different distal end shape instead.
Guiding catheter is a kind of composite conduit, comprises several different macromolecular materials and metal reinforcing mat, forms by the high temperature heating, has different variations from distal-to-proximal soft durometer.Because require internal diameter smooth, polyfluortetraethylene pipe uses usually at catheter diameter.Though guiding catheter looks that technology controlling and process is strict as uncomplicated, manually-operated cost height, each root guiding catheter all is single processing, if the technology imperfection, yield rate may reduce greatly.Just because of this, in operation, use many guiding catheters will increase the operation cost greatly.
The utility model content
The purpose of this utility model provides a kind of medical guiding catheter of head-bent controllable shapes, and this guiding catheter is simple in structure, and the shape that the flexible one-tenth of its head is required makes things convenient for the doctor to operate.
Above-mentioned purpose of the present utility model realizes by following technical solution: a kind of medical guiding catheter of head-bent controllable shapes, it is characterized in that: the head of described guiding catheter is embedded with becket, described becket is connected with an end of the steel wire of control head curved shape, the other end of steel wire stretches out outside the pipe of described guiding catheter, after described steel wire was subjected to the external force tractive, it made the head-bent of guiding catheter become required shape by the tension becket.
For the shape with the head of guiding catheter is controlled to needed shape, the soft durometer of catheter head can change, and the head of described guiding catheter is formed by the different plastic material combinations of hardness.Stage casing material hardness as the head of guiding catheter is the softest, the leading portion material hardness secondly, the back segment material is the hardest.
For the shape with the head of guiding catheter is controlled to needed shape, also can bury the tinsel that quantity does not wait underground along tube axial direction at the head of described guiding catheter.Bury tinsel underground and can adopt multiple mode, bury an one metal wire underground such as the front end edge tube axial direction at the head of described guiding catheter, tinsel is not buried in the stage casing underground, and its rear end is buried two one metal wires underground along tube axial direction, also can adopt other embedding manner.
Guiding catheter of the present utility model can be controlled the shape of guiding catheter head at catheter proximal end by handle by the doctor, and in operation process, the doctor does not need to change different guiding catheters, can reduce operating time, and can reduce patient's misery like this.To some patients, the shape of its coronary artery porch shape that is not accordant to the old routine, this has increased many difficulties for the doctor finds the coronary artery inlet.Use this utility model guiding catheter can adjust the preceding head shapes of guiding catheter at any time, make things convenient for doctor's operation.

The specific embodiment
The medical guiding catheter of a kind of head-bent controllable shapes as shown in Figure 1 and Figure 2, the head 11 of guiding catheter 1 is embedded with becket 2, becket 2 is connected with an end of the steel wire 3 of control head curved shape, and the other end of steel wire 3 stretches out outside the pipe of guiding catheter.After described steel wire 3 was subjected to the external force tractive, it made the head 11 of guiding catheter 1 bend to required shape by tension becket 2.
For the shape with the head of guiding catheter is controlled to needed shape, the soft durometer of catheter head can change, the head 11 of guiding catheter 1 is formed by the different plastic material combinations of hardness, and as shown in Figure 3, pipe 11b is the softest in the stage casing of head 11, leading portion pipe 11a secondly, 11c is the hardest for the back segment pipe, and when guiding catheter was crooked, stage casing pipe 11b's was crooked maximum, next is the position of leading portion pipe 11a, and the position of back segment pipe 11c is crooked minimum.For reaching required form, the soft durometer of head tubing can have more variation.
For the shape with the head of guiding catheter is controlled to needed shape, also can bury quantity underground or/and the different tinsel 4 of thickness along tube axial direction at the head 11 of guiding catheter 1, as shown in Figure 4, the front end edge tube axial direction of the head of guiding catheter is embedded with an one metal wire 4, tinsel is not buried in the stage casing underground, and its rear end is embedded with two one metal wires 4 along tube axial direction.The different tinsels different with thickness of quantity will be to the different soft durometer in each position, thereby when stretching, forms different case of bendings.
The steel wire of this utility model control head can be connected with the screw handle in the handle, and user can tighten up steel wire by the tighten the screws handle.After steel wire is received weak point, because guiding catheter 1 does not shorten, the head 11 of guiding catheter will buckle, and bend to as needed shapes such as Fig. 5, Fig. 6.
