Description
Technical field
This utility model relates to medical apparatus and instruments, specifically a kind of endoscopic angle guiding mechanism that is used for.
Background technology
On the clinical medicine, adopt endoscope to treat to be the at present the most frequently used diagnosis and treatment mode of the patient being damaged less both so-called Wicresofts.Traditional endoscope treatment needs cooperatively interacting of a plurality of doctors; The treatment effect of endoscope is high to doctor's technology and experience dependency; Because endoscope invades inspection in patient's body consuming time longer, this specification requirement for the doctor is higher, and also has high requirements for stability, the susceptiveness of endoscope apparatus; Avoid in patient's body, carrying out repeatedly angle adjustment, location, the high security of endoscope apparatus and high efficiency are to satisfy pressing for of clinical diagnosis treatment requirement.Because the operate miss that the long operation fatigue of operation doctor causes; When getting involved human body in endoscope probably; Bigger extruding force takes place in endoscope lens and tissue; When this extruding force surpasses certain threshold value, will cause the breakage of soft tissue, and then possibly cause the generation of malpractice such as tissue perforation.Present endoscope's prior art roughly has two kinds, and a kind of is that to adopt the angle slide block to carry out spacing, and another kind is the traction apparatus that has retaining mechanism; Former structure is simple, but the spacing reliability of angle is relatively poor, and independence and reliability that the latter is spacing are better; But complex structure, the relatedness of assembling between each part, interactive requirement height, higher to the degree of dependence of other devices of endoscope; Operating needs endoscope's integral body to cooperate adjustment, and endoscope's service efficiency is lower.
Known endoscope generally through scissor handle with turn to its bending of steel wire control to turn to, manipulation accuracy is not high, the control of angle is not accurate enough; Operation along with the medical worker in operation process is carried out; Angular adjustment apparatus uses repeatedly, turn to the angle of steel wire can be more or less deviation to some extent, make that the degree of accuracy of operation is not high; And owing to turn to the use repeatedly of steel wire; Can cause steel wire to twist, bend in endoscope inside, endoscope's angle adjustment sensitivity is low, brings hidden danger for the safety of operation.
The utility model content
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, a kind of endoscopic angle guiding mechanism that is used for to be provided, and it is simple to operate that it is had, the characteristics of convenient control steering angle.
The technical scheme of this utility model is achieved in that this utility model provides a kind of endoscopic angle guiding mechanism that is used for; Comprise angle adjustment steel wire, endoscope handle; It is characterized in that: also comprise nut, screw rod, said screw rod is installed in the locating hole on the endoscope handle, and said nut is arranged in the stopper slot of endoscope handle; Cooperate with screw rod; It is opening-like that one end of stopper slot is positioned at the endoscope handle surface, and the part of nut outer surface is positioned at the opening of the stopper slot on the endoscope handle, and said angle adjustment steel wire is connected with screw rod.
Preferably, the parallel axes of said screw rod and endoscope handle.
Specifically, be connected through connector between said screw rod and the angle adjustment steel wire, connector is a column; One end of connector is provided with screw thread, is provided with screw in the screw rod, and connector is connected with screw flight; The other end of connector is provided with connecting hole, and the angle adjustment fixation with steel wire is in connecting hole.
Preferably, said locating hole lays respectively at axial relative two sides in the stopper slot.
Furtherly, be provided with bearing between its locating hole and the screw rod.
A nearlyer step says that the width of its stopper slot and the width of nut adapt.
The utlity model has that spacing reliable, simple in structure, process and assemble is convenient, the independence of angle adjustment is strong and the characteristics of adjusting, convenient fixing.
Description of drawings
Fig. 1 is the structural representation of this utility model
Among the figure: 1. endoscope handle, 2. angle adjustment steel wire, 3. stopper slot, 4. nut, 5. locating hole, 6. screw rod, 7. connector, 8. screw, 9. connecting hole.
The specific embodiment:
Below in conjunction with the performance of accompanying drawing detailed description this utility model, but they do not constitute the restriction to this utility model, only do for example.
Shown in accompanying drawing: this utility model embodiment mainly comprises angle adjustment steel wire 2, endoscope handle 1; Nut 4, screw rod 6, screw rod 6 are installed in the locating hole 5 on the endoscope handle 1, and nut 4 is arranged in the stopper slot 3 of endoscope handle 1; Cooperate with screw rod 6; One end of stopper slot 3 is positioned at that endoscope handle 1 surface is opening-like, and the part of nut 4 outer surfaces is positioned at the opening of the stopper slot 3 on the endoscope handle 1, and angle adjustment steel wire 2 is connected with screw rod 6.The parallel axes of screw rod 6 and endoscope handle 1.Be connected through connector 7 between screw rod 6 and the angle adjustment steel wire 2, connector 7 is a column, and an end of connector 7 is provided with screw thread; Be provided with screw 8 in the screw rod 6; Connector 7 is threaded with screw rod 6, and the other end of connector 7 is provided with connecting hole 9, and angle adjustment steel wire 2 is fixed in the connecting hole 9.Locating hole 5 lays respectively at axial relative two sides in the stopper slot 3.Be provided with bearing between locating hole 5 and the screw rod 6.The width of the width of stopper slot 3 and nut 4 adapts.
This utility model has adopted nut 4 and screw rod 6 to solve the deficiency of prior art, and nut 4 matches with screw rod 6, seesaw through stirring nut 4 drive screw rods 6, and then the angle adjustment steel wire 2 of control connection on screw rod 6, carry out endoscope's angle adjustment.Become to have the screw thread of auto-lock function owing to nut 4 and the screw thread design that screw rod 6 matches; Make and be in course of adjustment and control screw rod 6 through nut 4; And then the angle adjustment steel wire 2 of control connection on screw rod 6; The control of nut 4 can be from exterior conductive to angle adjustment steel wire 2, can angle of arrival adjustment steel wire 2 owing to use repeatedly that torsional moment to occur excessive and retroaction and screw rod 6 force screw rod 6 to bounce back; Cause endoscope's angle-adjusting mechanism malfunctioning, angle of arrival adjustment steel wire 2 idle phenomenons.Screw rod 6 in this utility model is the most basic indispensable parts, can earlier nut 4 and screw rod 6 be dressed up assembly in when assembling, and then adopts screw to pack into this assembly and fix in the endoscope handle 1.
