Abstract
The utility model relates to a surgical instrument used for removing polyps inside vocal cords and nasal cavities. The utility model comprises a straight hollow concentric casing tube. The front ends of an inner and an outer casing tubes form an upswept front and an upswept back jaws. A suction hole is arranged on the inner casing tube between the jaws. The inner and the outer casing tubes are fixed on a handle. The relative motion of the inner and the outer casing tubes are controlled by the handle, and thereby, the closing of the jaws can be controlled. The utility model has forceps clamps, and is convenient to attract foreign matter, the polyps can be removed thoroughly, and the damage is small. The middle of the jaws and the inner and the outer casing tube has a plurality of angles, and the requirements for removing the polyps in a plurality of angles can be satisfied.
Description
This utility model belongs to medical surgical instrument, for a kind of being applicable to extractd polyp of vocal cord, polypous attraction bushing type operating forceps.
Be applicable to the excision vocal cords at present, polypous operating forceps is various in style, complete in specifications, but scarcely have and be unfavorable for attracting function, when being expert at enucleation, need use suction catheter simultaneously, absorb blood and secretions etc., thereby make troubles for clinical use, and big to normal tissue injury when extracing, have and attract function, effect is desirable not to the utmost, as polyp of vocal cord suction and cutting device, CN9220299.8, have concurrently during use and cut off and attract function, made things convenient for operation technique, shortened operating time, but also there are the following problems: (1) suction catheter has a bending, foreign material are easy to retain, and easy-clear and influence do not attract function; (2) the clamp function that does not possess conventional polyp forceps and had, then need adopt suction not of uniform size to cut head for the polyp that differs in size, there is certain difficulty when handling for polyp, the cyst of the diverse location beyond the vocal cords edge, the thing that swells etc., nasal polypus forceps with attraction function is to add a suction catheter in conventional nasal polypus forceps one side, suction catheter and jaw disalignment are unfavorable for operation technique.
Therefore, in order to satisfy clinical use, avoid the deficiency of existing apparatus, this utility model provides a kind of attraction bushing type polyp forceps, possess clamp and the convenient function that attracts, and suction catheter is coaxial with jaw, can accurately extract the polyp of vocal cords, nasal cavity rapidly, the cleaning foreign material, convenient, easily, and can satisfy the requirement of multi-angle.
Attract the bushing type polyp forceps, comprise empty concentric tubes always, the front end of internal and external casing constitutes the front and back jaw that upwarps, and has to attract the hole on the inner sleeve between the jaw, inner sleeve and trocar sheath are respectively fixed on the pincers handle, by the relative motion of pincers handle control internal and external casing.Thereby the closure of control jaw.
Below by description of drawings this utility model.
Fig. 1 is a structural representation of the present utility model, also is an embodiment.
Fig. 2 is 45 °, 135 ° jaw sketch maps.
Among the figure: 1 inner sleeve, 2 trocar sheaths 3 attract hole 4 jaws, 5,6 pincers handles
Among Fig. 1, the angle between jaw and internal and external casing is 90 °, and jaw also can be provided with multiple style, 45 °, 135 ° situation that shown in Figure 2 is, so that be applicable to polyp, the cyst of extracing diverse location, the thing etc. that swells,, more can satisfy the requirement of multi-angle especially for the intranasal polyp.The position, rear end of internal and external casing is separately fixed on two pincers handles 5,6, by the relative motion of pincers handle control internal and external casing, makes jaw free closed.During clinical use, at the back termination suction pump of inner sleeve, by the attraction of suction pump, polyp is attracted in the attraction hole 3, and control pincers handle 5,6 makes jaw 4 closures, can extract polyp smoothly, inner sleeve double as suction catheter, the polyp that blood, endocrine, quilt are cut off is also absorbed by suction catheter.
Advantage of the present utility model:
1, the utility model namely has the clamp function of conventional polyp forceps, can conveniently attract again, and suction tube, jaw is coaxial, easy to use, have simplified operating procedure, have shortened operating time, and it is thorough to extract polyp, and the normal tissue damage is little.
2, adopt straight concentric tubes, sturdy and durable, be convenient to cleaning, suction is strong.
3, can satisfy the requirement of extracing vocal cords, polyp of nasal cavity multi-angle, little disguised polyp is particularly used.
Therefore the utlity model has clinical generalization value.
