Abstract
The invention discloses a flexible shaft apparatus for medical treatment. The flexible shaft apparatus comprises a steel wire rope; the steel wire rope is in a half-folded structure and comprises a double wire head end and a half-folded end, wherein the half-folded end is encircled to form a sleeve ring; and the double wire head end is wrapped with a flexible shaft. By using the flexible shaft to replace a rigid surgical cutter component which is directly made by machining metal, the flexible shaft apparatus has relatively high strength and toughness; and usually, the structural constraint of the flexible shaft apparatus is extremely fine, so that the apparatus can meet the requirements of a minimally-invasive surgery. In addition, the flexible shaft apparatus for the medical treatment is small and exquisite in structure and simple in operations, is time-saving and labor-saving, and can reduce the pain of a patient.
Description
Technical field
The present invention relates to the medical machinery field, relate in particular to a kind of flexible shaft appliance for medical treatment and application thereof.
Background technique
Flexible axle is present mechanical field connection for transmission apparatus commonly used, usually is entwined by steel wire spiral, has certain mechanical strength and the ability of anti-deformation, along with the extensive use of flexible axle, also gradually relates to application in the clinical treatment Minimally Invasive Surgery.
The at present for example so small-sized operation of nasal polyp excision, owing to the restriction of operating space and in line with the principle to patient's minimally invasive, mostly adopt more tiny cutter to carry out the Minimally Invasive Surgery operation, such as Chinese patent CN201211212Y " nasal polyps remover ", this cutter is because this body structure is smaller skilful, cutting operation is smaller to patient's damage, progressively promoted by everybody, but because this cutter is generally all thinner, not very high with its intensity of metal machining and toughness directly, and the development trend of this cutter is more and more less, and this just has higher requirement to intensity and the toughness of cutter.
Summary of the invention
Defective in view of above-mentioned prior art exists the objective of the invention is to propose a kind of flexible shaft appliance for medical treatment and application thereof with higher-strength and toughness.
Purpose of the present invention will be achieved by the following technical programs:
A kind of flexible shaft appliance for medical treatment comprises a wire rope, and described wire rope is to folded structure, comprises two-wire head end and doubling end; Described doubling end ring is around forming a collar; The outside of described two-wire head end is enclosed with flexible axle.
Preferably, above-mentioned a kind of flexible shaft appliance for medical treatment, wherein: described wire rope is to be rolled up by at least 2 finer wire strand to form.
Preferably, above-mentioned a kind of flexible shaft appliance for medical treatment, wherein: described flexible axle comprises 2 ~ 3 layers steel wire winding layer, every layer of steel wire winding layer by 4～8 steel wires side by side spiral winding form.
The application of above-mentioned a kind of flexible shaft appliance for medical treatment when being used for operation, is enclosed within the described collar on the base of a fruit of polyp bottom, and it is not easy distortion the counter-bending property preservation of dependence flexible axle, and the pulling flexible axle cuts away polyp, and the intensity of wire rope guarantees that it is not broken simultaneously.
Outstanding effect of the present invention is: utilize flexible axle to replace the rigidity surgical knife tool parts that directly process with metal, utilize the steel wire of internal layer rope can bear the tensile properties of larger pulling force, and the structure of outer flexible axle has certain non-deformability and support performance, thereby make apparatus of the present invention have higher intensity and toughness, and structural limitations generally all is very thin, can satisfies the requirement of Minimally Invasive Surgery, structure is small and exquisite, simple to operate, time saving and energy saving, reduce the patient suffering.
Following constipation closes embodiment's accompanying drawing, the specific embodiment of the present invention is described in further detail, so that technical solution of the present invention is easier to understand, grasp.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention 1.
Embodiment
Embodiment 1:
A kind of flexible shaft appliance for medical treatment of present embodiment as shown in Figure 1, comprises wire rope 1, and wire rope 1 is to folded structure, comprises two-wire head end and doubling end, and the doubling end ring is around forming a collar 2; The outside of two-wire head end is enclosed with flexible axle 3.Wherein wire rope 1 is to be rolled up by at least 2 finer wire strand to form.Flexible axle 3 comprises 2 ~ 3 layers steel wire winding layer, every layer of steel wire winding layer by 4～8 steel wires side by side spiral winding form.When above-mentioned a kind of flexible shaft appliance for medical treatment is used for operation, the collar 2 is enclosed within on the base of a fruit of polyp bottom, it is not easy distortion the counter-bending property preservation of dependence flexible axle 3, and pulling flexible axle 3 cuts away polyp, and the intensity of wire rope 1 guarantees that it is not broken simultaneously.
Present embodiment utilizes flexible axle 3 to replace the rigidity surgical knife tool parts that directly process with metal, utilize steel wire of internal layer rope 1 can bear the tensile properties of larger pulling force, and the structure of outer flexible axle 3 has certain non-deformability and support performance, thereby make apparatus of the present invention have higher intensity and toughness, and structural limitations generally all is very thin, can satisfies the requirement of Minimally Invasive Surgery, structure is small and exquisite, simple to operate, time saving and energy saving, reduce the patient suffering.
The present invention still has numerous embodiments, and all employing equivalents or equivalent transformation and all technological schemes of forming all drop within protection scope of the present invention.
