Using the utility model, excision and suture can be completed once, the operation is convenient, the anastomosis is firmed, blood-stanching is thorough, the operation time is short, the quality is excellent, and is applied to various internal hemorrhoids, mixed hemorrhoids, in particular to the resection operation of the ring-shaped hemorrhoids.

Description

The cast hemorrhoid anastomat

(1) technical field: this utility model belongs to medical mechanical domain, is to be used for a kind of cast hemorrhoid anastomat that each phase internal hemorrhoid, mixed hemorrhoid, particularly ring-type hemorrhoid are used as resection operation.

(2) background technology: hemorrhoid are multiple diseases of a kind of stubbornness, the domestic apparatus that is used for the treatment of hemorrhoid mainly is to adopt multi-functional hemorrhoid suction and ligature device at present, the pistol-shaped suction and ligature device that can be used for clinical suction, cover, the art of pricking the hand, by produce negative pressure system, push away bundle, disappear pressing system and body, handle casing etc. form, treatment to internal hemorrhoid, rectal polyp, in early days, under the one situation of internal hemorrhoid, can obtain certain curative effect.The problem that exists is: 1. can not effectively handle the ring-type hemorrhoid; 2. multiple blood stasis can not disposablely be handled; 3. can't treat prolapse of rectal mucosa.

(3) summary of the invention: the purpose of this utility model is at the problems referred to above, provides a kind of and can effectively treat the ring-type hemorrhoid, and can solve the problem of prolapse of rectal mucosa, and operating time is short, the measured cast hemorrhoid anastomat of matter.

Concrete scheme of the present utility model is: get a tubular outer casing, load onto an annular push rod within it, the centre is coated with the nail supporting base center-pole, the center-pole tail end is shaped on screw thread and is threaded with a nut frame, the fixedly connected knob in nut frame rear end, knob is connected with the tail end position rotating of tubular shell; Front end at annular push rod is equipped with annular cutting knife, and adopts protective sleeve location, the tail end of annular push rod to connect a cutting handle, and the cutting handle is on the hinged boss that is contained in the tubular shell outer wall of crank-like; Front end at tubular shell also is equipped with the nail seat; Have through wires hole on the middle part of tubular shell and the correspondence position of annular push rod.

This utility model is easy to operate, coincide firmly, and hemostasis is thoroughly excised, sewed up and once finish, and operating time is short, quality good, is suitable for various internal hemorrhoid, mixed hemorrhoid, particularly ring-type hemorrhoid are carried out resection operation, and has solved the problem of prolapse of rectal mucosa.

(4) description of drawings: accompanying drawing is a structure cutaway view of the present utility model.

Among the figure: the 1-nail supporting base, the 2-endless knife, 3-anastomosis staple, 4-are followed closely seat, the 5-protective sleeve, 6-annular push rod, the 7-through wires hole, 8-nail supporting base center-pole, the 9-tubular shell, 10-nut frame, the 11-knob, 12-cuts handle, 13-boss.

(5) specific embodiment: this utility model mainly adopts rustless steel to make each parts, and its assembly structure is referring to accompanying drawing, in the tubular shell 9 of at first annular push rod 6 being packed into; The front end of annular push rod 6 is equipped with endless knife 2; and adopt protective sleeve 5 location to protect; the tail end of annular push rod 6 has connecting hole, and the thrust end of cutting handle 12 inserts connecting hole and is connected with annular push rod 6, and cutting handle 12 is to be hingedly mounted on the tubular shell outer wall boss 13.Reinstall nail supporting base center-pole 8 (it and nail supporting base 1 are made as one).The rear of center-pole 8 is shaped on screw thread, is threaded with nut frame 10, and nut frame 10 is fixedly connected with knob 11, and 11 of knobs are connected with the tail end position rotating of tubular shell 9.Front end at tubular shell 9 also is equipped with nail seat 4, and the anastomosis staple 3 of packing in use; On the correspondence position of the middle part of tubular shell 9 and annular push rod, have through wires hole 7.

When this utility model uses, at first hold tubular shell 9 nail supporting base 1 is pushed in patient's anus, to affected area.Turn knob 11 makes nail supporting base 1 to accurate position thereby drive nut frame 10 rotation promotion nail supporting base center-poles 8; The downward crush-cutting of hands cuts handle 12 then, works forward thereby promote annular push rod 6, and ring table cutter 2 is thereupon with the hemorrhoid excision, and anastomosis staple 3 is depressed otch is coincide simultaneously.
