Abstract
The utility model discloses a medical trestle weaved with special shaped wires to solve the problems that the trestle in prior art has small radical supporting force and the transferring device has larger diameter. The utility model is weaved with titanium alloy or stainless steel wires along the surface of a cylindrical mould in a staggered normal and reverse helix way. The utility model mainly comprises a diamond shaped mesh type cylinder, of which two ends are provided with cup shaped, sphere shaped or horn shaped ends set by heat treatment for preventing displacement of the trestle in body cavity, the terminal of the end has larger diameter than the cylinder, and the connections between the cylinder and the cup shaped, sphere shaped or horn shaped ends at two ends are arc spontaneous transition. The utility model is characterized in that the titanium alloy or stainless steel wire has non-circular cross section, and the reentry parts of the wire at two ends stagger up and down. The utility model has the advantages of convenient operation and large supporting force.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of apparatus for the treatment of the narrow and fistula of body cavities, specifically a kind of medical support by the braiding of special-shaped silk material.
Background technology
At present, at esophagus and similarly to insert the narrow and fistula of stent in the treatment in the human body organ be a kind of effective method for treatment, it has, and wound is little, patient is painful little, the characteristics that surgery cost is low, be particularly useful for inoperable gerontal patient, can significantly improve patient's living condition.
In order to treat the narrow of body cavities, people have invented a material braided support of using of different shape, and they all use round silk material.For making support obtain bigger radial support power, just need to strengthen the diameter of round silk material, the increase that can bring the stent conveying device diameter thus finally in use may cause more misery to the patient.In addition, the head of support is made up of the silk material of turning back, and generally need take bigger space in diametric(al), needs to compress by force just can enter conveyer device, and is also relatively more difficult during release, must be improved.
Summary of the invention
The purpose of this utility model be little at existing support radial support power, turn back unreasonable structure and need the big problem of conveyer device installing space, it is big to design a kind of radial support power, the medical support by the braiding of special-shaped silk material that the conveyer device installing space that needs is little.
The technical solution of the utility model is:
A kind of medical support by the braiding of special-shaped silk material, it is formed with the die surface winding braiding of the staggered mode of passing through of positive and negative helix along a certain cylindrical shape by Nitinol or stainless steel silk material, its main body latticed cylinder that assumes diamond in shape, cylindrical two ends are provided with and prevent that support from producing displacement in body cavities and the cup type of heat treatment typing, ball-type or trumpet type end, the diameter of its end tip is greater than cylindrical diameter, the cup type of cylinder and two ends, circular arc nature transition between ball-type or the trumpet type end, the cross section that it is characterized in that described Nitinol or stainless steel silk material is a non-circular structure, and the position that the silk material of two end ends is turned back is height shape straggly, is different from the concordant unanimity of conventional stent.Use the support of this structure braiding, make its turnover conveyer device become more easy.
The cross sectional shape of described silk material is square, rectangle, Long Circle or ellipse.By the support of special-shaped silk material braiding, compare with a traditional support by the braiding of circle silk, under the constant situation of the radial support power of support, the wall thickness of support is less, can adopt thinner stent conveying device.
Described cylindrical surface is coated with columned silica gel thin film of one deck or PTFE thin film.
The utlity model has following advantage:
1, easy to operate, can use existing laying method this product to be placed in patient's the body more easily.
2, by the support of special-shaped silk material braiding, under the situation of same radial support force, can adopt thinner conveyer device.
3, utilize the variation of bracket end preparation method, make support pass in and out its conveyer device and become more easy.When discharging ERCP biliary tract rack or intestinal support, needs use length is the releasing device about 2 meters usually, and the design's advantage is more outstanding.

The specific embodiment
Below in conjunction with drawings and Examples this utility model further there is explanation.
As shown in Figure 1.
A kind of medical support by the braiding of special-shaped silk material, by cross section is that rectangle (as Fig. 2) Nitinol or stainless steel silk material 1 form with the die surface winding braiding of the staggered mode of passing through of positive and negative helix along a certain cylindrical shape, its main body latticed cylinder 2 that assumes diamond in shape, the two ends of cylinder 2 are provided with and prevent that support from producing displacement in body cavities and ball-type (also can become cup type or trumpet type by mould shape when the specifically implementing) end 3 of heat treatment typing, 4, its end 3, the diameter of 4 ends is greater than the diameter of cylinder 2, cylinder 2 and end 3, circular arc nature transition between 4 the ball-type body, and two end ends 3, the position 5 that 4 silk material is turned back is height shape straggly, as Fig. 5.Can coat columned silica gel thin film of one deck or PTFE thin film on the surface of cylinder 2 in addition.As required, need take out in body as support, the two ends of support need overlay film, otherwise, do not need overlay film.
Also can adopt rectangle, rhombus or the oval silk material of cross sectional shape shown in Fig. 3,4 to weave during concrete enforcement as required.By the support of special-shaped silk material braiding, compare with a traditional support by the braiding of circle silk, under the constant situation of the radial support power of support, the wall thickness of support is less, can adopt thinner stent conveying device.Therefore adopting shaped filaments material braided support is the place of key of the present utility model, and the support everywhere of all this principle design of employing all is considered to be encompassed among the protection domain of the present utility model.
Claims (2)
1, a kind of medical support by the braiding of special-shaped silk material, it is formed with the die surface winding braiding of the staggered mode of passing through of positive and negative helix along a certain cylindrical shape by Nitinol or stainless steel silk material, its main body latticed cylinder that assumes diamond in shape, cylindrical two ends are provided with and prevent that support from producing displacement in body cavities and the cup type of heat treatment typing, ball-type or trumpet type end, the diameter of its end tip is greater than cylindrical diameter, the cup type at cylinder and two ends, circular arc nature transition between ball-type or the trumpet type end, the cross section that it is characterized in that described Nitinol or stainless steel silk material is a non-circular structure, and the position that the silk material of two end ends is turned back is height shape straggly.
