Description
Technical field
The present invention relates to a kind of armarium, particularly a kind of Wicresoft separating knife.
Background technology
In the prior art,, generally all there are tissue adhesion and hamartoplasia in patient's joint, the soft tissue, at this moment, need carry out Minimally Invasive Surgery, separate and the removing pathological tissues the patient for rheumatism or other similar conditions.And traditional separating knife can only be undertaken by range estimation, can't accurately operate, for the perceptual knowledge of how much having only of removing pathological tissues, do not have accurate recording, thereby the success rate of operation depends on concrete operations personnel's personal experience mostly, it is not thorough often to cause pathological tissues to be removed, and curative effect is undesirable, and success rate of operation is low.
Summary of the invention
The purpose of this invention is to provide a kind of Wicresoft spacing separating knife, novel structure, easy to operate, accurate, the success rate of operation height, patient's rehabilitation is fast.
Technical scheme of the present invention is: a kind of Wicresoft spacing separating knife, comprise handle of a knife, knife bar and broach shell pipe, and described handle of a knife comprises the first cutter ear and the second cutter ear of cross-articulation, the described first cutter ear top is positioned at the vertical rear of the second cutter ear; Described knife bar activity is plugged in the broach shell pipe, and the front end of knife bar is provided with the cutter head that can stretch out or bounce back with respect to the broach shell pipe, and the rear end stretches out in outside the broach shell pipe and is connected in the top of the first cutter ear; Telescopic front end of described cutter and knife bar stretch out to the place ahead of handle of a knife jointly, and the top of the second cutter ear is located in the telescopic rear end of cutter; Be provided with many graduation marks of spacing when being used to operate on the revealed section on the described knife bar between the first cutter ear and the second cutter ear.
The present invention can do following improvement, and the top of the described second cutter ear is provided with the horizontal channel that described knife bar is passed, the telescopic intracavity inter-connection of this horizontal channel and cutter, and promptly described knife bar inserts in the described broach shell pipe via this horizontal channel.
Second cutter ear of the present invention and broach shell pipe are connected as a single entity.
The present invention can also do following improvement, and described handle of a knife is provided with the return mechanism that the cutter head retraction that can make on the described knife bar resets.
Return mechanism of the present invention comprises the first return sheet and the second return sheet of being located at respectively on the first cutter ear and the second cutter ear, and an end of two return sheets is individually fixed in the inboard of the first cutter ear and the second cutter ear, and the other end is bent upwards and links to each other.
The length of described broach shell pipe and knife bar adapts, and the diameter that the corresponding front end of the described cutter head of described broach shell Guan Shangyu is a section is greater than the diameter at position beyond this section on the broach shell pipe.
The invention has the beneficial effects as follows:
Wicresoft of the present invention spacing separating knife, novel structure, owing to be provided with the graduation mark that is used to weigh the cutter head working depth on the revealed section of knife bar, the position of can be exactly needs being removed treatment be operated, difficulty is little, improved success rate of operation greatly.Separating knife of the present invention can be widely used in adhesion and outgrowth tissue in rheumatismal joint, the soft tissue, and the joint appears in intractable rheumatism such as rheumatoid arthritis, ankylosing spondylitis, osteoarthritis etc., flesh muscle local intractable swells and ache.
Below further prove beneficial effect of the present invention by the clinical experiment case:
Case 1: patient Song *, the woman, 29 years old, the patient was surplus because of both shoulders arthralgia repeatedly 3 years, the limited prescription on individual diagnosis of companion's joint motion, the patient begins to occur both shoulders arthroncus, pain because of no obvious inducement before 3 years, pain is obvious night, weather cool off or rainy day pain increase the weight of, lift limited on companion's both hands, be diagnosed as " rheumatoid arthritis " on inspection
Row both shoulders joints " Wicresoft's pin cutter mirror art ", find in the art that synovial hyperplasia in the articular cavity, pannus form, the tissue adhesion considers that the shoulder joint chamber is narrower, for avoiding damaging local cartilage and joint, satisfy and under mirror, use Wicresoft's spacing separating knife, can treat by set a distance, separate outgrowth synovial membrane, pannus, remove the tissue adhesion, the postoperative arthralgia is alleviated, improving action.
Case 2: the patient what * *, the woman, 48 years old, the patient because of right shoulder joint repeatedly swell and ache 1 year surplus, companion's joint deadlock in morning, limitation of activity is gone to a doctor, and the patient begins to occur right shoulder joint because of no obvious inducement before 1 year and swells and ache, joint motion is limited, companion joint deadlock in morning, the stiff time in morning surpasses 1 hour, is diagnosed as " rheumatoid arthritis " on inspection, then give methotrexate, leflunomide, Drug therapy such as meloxicam and Chinese medicine, the local acupuncture of row, iontophoresis, physical therapys such as herbal fumigation, the right shoulder joint of patient swells and ache and still shows effect repeatedly, and joint motion is limited, improve not obviously, therapeutic effect is undesirable.
Curative effect by above two cases more as can be known, Wicresoft of the present invention spacing separating knife can have accurate separation pathological tissues and treatment, removes sufferer.
