Problems solved by technology

However, there are still some deficiencies in this patented technology. Because its biaxial structure is distributed side by side in the endoscope operating part, there is still room for reducing the radial size of the operating part structure of the endoscopic device of this kind of biaxial parallel rotating connection mechanism. Further increase in operating comfort
In addition, the dual-axis parallel rotary connection mechanism results in more pores in the connection between the insertion part of the endoscope device and the rotary connection mechanism of the operation part, and the sealing of the connection needs to be improved

Embodiment 1

[0050] The first embodiment of the present invention is a double thread method of nut screw type, refer to Figure 1 to Figure 10 Be explained. The purpose of this embodiment is to respectively realize the reciprocating motion of the pulling wire group 12 (specifically, the reciprocating motion of the pulling wires 12a and 12b and the pulling wires 12c and 12d) through the rotation of the first rotating shaft 33a and the second rotating shaft 34a. ).

[0051] like figure 1As shown, the rotating endoscope device provided by this embodiment is composed of two parts, the insertion part 1 and the operation part 2. The shaft rotates the connection mechanism 3 to realize the detachable connection. The insertion part 1 mainly includes a bending unit composed of a driving steering unit 11 , a drawing wire group 12 and a snake bone unit 13 , as well as an illumination unit 14 and an imaging unit 15 . The bending unit has at least two bending directions. The operating part 2 includ...

Embodiment 2

[0067] Figure 16a and Figure 16b Example 2 will be described. This embodiment mainly transforms the drive steering unit 11 into a drive differential shaft type belonging to the category of double threads. The second rotating shaft 34a is connected by a lateral transmission (gears, belts, sprockets). Other than that, the basic structures of the operation part and the insertion part of this embodiment are basically the same as those of the first embodiment. The purpose of this embodiment is to respectively realize the reciprocating motion of the pulling wire group 12 (specifically, the reciprocating motion of the pulling wires 12a and 12b and the pulling wires 12c and 12d) through the rotation of the first rotating shaft 33a and the second rotating shaft 34a. ).

[0068] like Figure 16a and Figure 16b As shown, the other end of the first rotating shaft 33a is fixed with a first nut unit 11a and a second nut unit 11b, and the second rotating shaft 34a meshes with a spur...

Embodiment 3

[0070] Figure 17 Example 3 will be described. This embodiment mainly transforms the drive steering unit 11 into a drive coaxial type under the category of single thread. The first rotating shaft 33a and the second rotating shaft 34a change the direction of the pulling wire through a phase changing unit (gear, pulley, belt, sprocket). Other than that, the basic structures of the operation part and the insertion part of this embodiment are basically the same as those of the first embodiment. The purpose of this embodiment is to respectively realize the reciprocating motion of the pulling wire group 12 (specifically, the reciprocating motion of the pulling wires 12a and 12b and the pulling wires 12c and 12d) through the rotation of the first rotating shaft 33a and the second rotating shaft 34a. ).

[0071] like Figure 17 As shown, the other end of the first rotating shaft 33a is fixed with the first nut unit 11a, and the end of the second rotating shaft 34a is fixed with th...

Abstract

The invention provides a rotatable endoscope apparatus, which comprises an inserting portion and an operating portion, wherein the inserting portion at least comprise a bending unit which has two bending directions and a first dual-coaxial rotary connecting mechanism which is connected to the bending unit; the operating portion at least comprises a bending driving unit and a second dual-coaxial rotary connecting mechanism which is connected to the bending driving unit; and the inserting portion and the operating portion are detachably connected by virtue of the first dual-coaxial rotary connecting mechanism and the second dual-coaxial rotary connecting mechanism, so that the bending directions of the bending unit, which is driven by virtue of the bending driving unit, are switches. The rotatable endoscope apparatus is simple and convenient in maintenance, good in safety and reliability, good in connecting sealing performance and good in operating comfort.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an endoscope, in particular to a rotating endoscope device. Background technique [0002] In the field of medical instruments, such a rotary endoscope device has been developed so far: the device is composed of four drive rods and bevel gear sets arranged in pairs. The driving rod transmits the driving force through the engagement of the bevel gears to realize the bending of the front end of the endoscope. [0003] Patent document: Chinese patent number is: ZL 200910086832.9, a living body observation device. Embodiment 3 described in this patent document is to connect the endoscope device in an engaging manner. This device is a rotary endoscope device, and its drive rods are arranged side by side. In addition, the insertion part and the operation part can be assembled and disassembled, so that only the insertion part of the endoscope can be replaced and disinfected each tim...
