Description

Endoscopy swing head device

Technical field

The present invention relates to a kind of endoscopy swing head device, particularly a kind ofly formed and can be two-way or the endoscopy swing head device of unidirectional swing by elastic parts and two-way flexible body.

Background technology

At present, endoscopy swing head device is widely used in detecting on the digestive organ.See also the 1st figure, it is the schematic diagram of the endoscopy swing head device of prior art.Among the figure, the front end of endoscopyswing head device 91 is provided withyaw structure 92, a plurality ofannular metal 93 and a plurality of rivet 94.Be provided with the endoscope (not shown) in theyaw structure 92, eachannular metal 93 has opposed facing thefirst rivet hole 95 and the second rivet hole (not shown), eachrivet 94 penetrates respectively in thefirst rivet hole 95 and the second rivet hole, to connect annular metal 93.First Line body 96 or thesecond line body 97 are arranged in a plurality ofannular metals 93, and connect yaw structure 92.By this, in the time of can seeing throughFirst Line body 96 or thesecond line body 97 and spur respectivelyyaw structure 92,yaw structure 92 is turned to, camera lens with the control endoscope, cause endoscope to enter into body internal cavity volume, such as stomach etc., can observe the tissue image of most inside cavity.

But, the endoscopyswing head device 91 of prior art necessarily requires dimensional accuracy to reach below the 0.2mm because of its eachannular metal 93, thefirst rivet hole 95, the second rivet hole and rivet 94, keeping structural precision, thus will cause the loaded down with trivial details and cost of production roll up, expensive.

Moreover, because eachannular metal 93 structural restriction of the endoscopyswing head device 91 of prior art, the angle that makes its turnover to some extent limit is fixed, and do not reach large-scale turning angle, therefore can't intactly observe the tissue image of inside cavity, cause the shortcoming of omitting a certain tissue image of inside cavity, allow the two-way swinging head of traditional endoscope be installed on and be subject to great restriction in the application.

In addition, when in case theFirst Line body 96 that will spur or thesecond line body 97 get loose, theannular metal 93 of each bending can't be kept in the center, and be anchored in the angle in when pulling, user must spur otherFirst Line body 96 or thesecond line body 97, to the script position, will cause greatly inconvenience of user with theannular metal 93 of replying bending.

Because every problem of the prior art, in order to take into account solutions, the inventor proposes a kind of endoscopy swing head device based on for many years research and development and many practical experience, with implementation and the foundation as the above-mentioned shortcoming of improvement.

Summary of the invention

In view of this, purpose of the present invention is to provide a kind of endoscopy swing head device exactly, utilizes bent elastic parts and flexible body, and the two-way and unidirectional shaking device of endoscope simple in structure can be provided.
