Abstract
The utility model relates to a suction and cutting device for polypus of vocal cords, belonging to medical sanitary ware and comprising a cutting grinding head (1), a positioning nut (2), a catheter (3), a handle (4), a fixing screw (5), a copper net (6), and a pressure regulation port (7). The suction and cutting device can keep the vocal cord healthy and the tissue perfected and intacted, can be used for treating the polyp of a vocal cord, and is also suitable for removing the palilloma of the throat, various granulation of laryngopharynx, and neoplastic biopsy.
Description
This utility model relates to a kind of polyp of vocal cord suction and cutting device, and it belongs to the health care utensil.Be used in particular for treating polyp of vocal cord, also be applicable to the various granulations of papillomatous excision of throat and laryngopharynx portion, neoplastic biopsy.
Polyp of vocal cord also claims laryngeal polyp, is the department of otorhinolaryngology common chronic disease.The current means that all adopt the polyp of vocal cord pincers to extract of this disease are treated.Polyp of vocal cord clamps the mechanical implement that is based on shearing mechanism and makes, as shown in Figure 1, technical merit to the doctor when these polyp of vocal cord pincers use requires high, especially to the hidden polyp of small polyps or position, be difficult for reaching therapeutic purposes, and the long surgical effect of operating time is not ideal enough, doctor's operating difficulties and patient's misery have been increased, therefore, the past is difficult to popularize to this operation and promotes, and its curative effect is also not ideal enough sometimes.
The purpose of this utility model is a kind of polyp of vocal cord suction and cutting device that provides at the deficiency of prior art, and it adopts suction to cut principle and makes it easy and simple to handle, operation safety, and curative effect is thorough, has overcome the deficiency of prior art effectively.
The purpose of this utility model is achieved in that
A kind of polyp of vocal cord suction and cutting device is characterized in that: it comprises cuts bistrique (1), setscrew nut (2), conduit (3), handle (4), hold-down screw (5), copper mesh (6), regulation and control pressure port (7) composition;
Conduit (3) is a curved catheter, is provided with one " pressure control opening " in suitable forefinger holding area, and catheter tip connects vacuum pump, and front port is made screw thread mouth, can the different annular cutter of changing-over.
Be provided with passage in the handle (4) and can supply conduit (3) to walk, handle can be two or more by screw (5) fixed support conduit hold-down screw.
Cutting bistrique (1) is dissimilar annular cutters, and it can be to cut nose cone to cut head, tiltedly cut head, side plain grinding head, garden bistrique, side garden bistrique, plain grinding head, bevel grinding head, and they are installed on the front port of conduit, locate with setscrew nut.
Copper mesh (6) places the front port place of conduit, is promptly cutting between bistrique (1) and conduit (3) contact surface, and copper mesh is 100～200 orders.
Setscrew nut (2) is anchored on the front end screw thread of conduit.
Conduit adopts various plating network metal materials (as copper) or non-toxic duroplasts (as polyethylene) or rustless steel or 9Cr18MoV to make.
Handle is made by lucite or bakelite or duroplasts (as ABS plastic) etc.
Annular cutter all can be made by various plating network metal materials (as copper) or rustless steel or 9Cr18MoV.
Setscrew nut is made by plating network metal material or non-toxic duroplasts or rustless steel or 9Cr18MoV.
This utility model is owing to be based on the controllable negative pressure attraction principle, polyp of vocal cord sucked annular cutter and it is cut off, and therefore existing polyp of vocal cord pincers based on shearing mechanism had essential improvement, obviously is better than conventional polyp of vocal cord pincers.This utility model can keep the vocal cords health tissues intact, the suction hole that head is cut in suction is provided with the plurality of specifications that varies in size, opening with different directions can be selected suitable model for use according to pathological changes size and position, and the operation motility is good, compare with conventional larynx polypus forceps, have attraction accurately, operating time is short, does not damage normal structure, characteristics such as healing is fast, and operation technique is easy.
Fig. 1 is conventional polyp of vocal cord pincers sketch map.
1 ' ┄ cutter, 2 ' ┄ hinge, 3 ' ┄ conduit, 4 ' ┄ operating grip wherein.
Fig. 2 is a structural representation of the present utility model.
Describe formation of the present utility model and work process in detail below in conjunction with accompanying drawing.
Vacuum pump suction pump (centre can connect negative pressure bottle) is connected suction and cutting device tip catheter mouth, suction and cutting device front end and conduit mouth are installed the annular cutter (1) that is suitable for sick body (polyp) in advance, be adjacent to sick body during operation, when suction pump work, forming negative pressure produces suction and regulates suction with finger by regulation and control pressure port (7), just the polyp of vocal cord tissue can be sucked in the attraction hole of annular cutter, lift suction and cutting device again after suitably rotation makes its ring cutting then, polyp is promptly cut off, and surrounding tissue is harmless, the copper mesh that is installed in catheter proximal end mouth place can prevent that sick body excessively is inhaled into so that damage the substrate normal structure, and the polyp that is cut can not clean down to stopping up the conduit obstruction by the suction catheter tube chamber.
The polyp of vocal cord suction and cutting device also can be machined for the excision and the various granulation of inside and outside each the position tumor of health as required.The operating theater instruments of neoplastic biopsy etc.
Bistrique in the cutter is used in treatment film projection (polyp forms early stage), the small tuberosity of vocal cords, and roughness increases the pathological changes that rear portion etc. should not be cut, and bistrique was both available lever operated also can be made into by the transmission of low speed flexible axle.
The bistrique work surface adopts the spraying fine emery powder to make.
