Description
Technical field
The utility model relates to the field of medical instrument technology, in particular to a kind of endoscopic procedure portion A-frame.
Background technique
Medical stomach endoscopic procedure handle front end is connect with insertion tube, and rear end is connect with light pipe.Due in operation portion
The limitation of portion's structure and space, the A-frame that light pipe passes through inside operation portion with operation portion at present link together.City
The structure of A-frame installation inside stomach endoscopic procedure portion on face is as shown in Figure 1, the A-frame structure type is multiple
It is miscellaneous, it needs Multi-step forming to form or needs complicated continuous stamping die to make, technique is more complex, higher cost；In addition
The casing surface connecting with A-frame is cylindrical surface, and the joint face that 3 stabilizer blades of A-frame converge is by several planes
It bends, rather than Cylinder Surface, therefore is bonded with the surface of pipe sleeve bad, positioning accuracy is not high, to the established angle of light pipe
Degree produces a very large impact, if setting angle deviation is too big, will cause strong influence to the sealing between rear cover and light pipe.
Utility model content
In view of the above drawbacks of the prior art, the technical problem to be solved by the utility model is to provide a kind of structure letters
It is single, facilitate processing, accurate installation positioning, the endoscopic procedure portion three of the good setting angle that ensure that light pipe can be reached
Angle support.
Technical solutions of the utility model are as follows:
A kind of endoscopic procedure portion A-frame, including the first stabilizer blade, the second stabilizer blade and third stabilizer blade, first stabilizer blade,
The upper surface of second stabilizer blade and third stabilizer blade is connected by joint face, and the joint face is arc-shaped, the company of arc top upward
The side of junction is connect with the upper end of first stabilizer blade, the other side of the joint face and second stabilizer blade and third stabilizer blade
Upper end connection.
Preferably, the lower end surface of first stabilizer blade, the second stabilizer blade and third stabilizer blade is in the same plane.
Preferably, the equal outward flanging in lower end of first stabilizer blade, the second stabilizer blade and third stabilizer blade, forms trunnion.
Preferably, the width of first stabilizer blade, the second stabilizer blade and third stabilizer blade is respectively less than the width of the joint face.
Preferably, first stabilizer blade and the second stabilizer blade are symmetricly set on the two sides of the joint face, and this first
One of end face of foot and the second stabilizer blade and the joint face.
Preferably, mutual angled setting between second stabilizer blade and third stabilizer blade.
Preferably, the joint face is plane, other end end close to one end end face of the first stabilizer blade and the second stabilizer blade
Face is cambered surface.
Preferably, be symmetrical arranged on the joint face there are four screw counter sink, first stabilizer blade, the second stabilizer blade and
First through hole, the second through-hole and third through-hole are respectively arranged on the trunnion of third stabilizer blade.
The utility model has the advantages that the A-frame structure type of the utility model is simple, moulding process is simple, can be real after the completion of blanking
Existing single punch forming, manufacturing cost are lower；The joint face that A-frame connects 3 stabilizer blades is arranged to cylindrical surface, with pipe sleeve
Surface fitting preferably, improve positioning accuracy, the setting angle of light pipe also made to be guaranteed.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the A-frame of the prior art；
Fig. 2 is the structural schematic diagram of the utility model；
Fig. 3 is the rearview of Fig. 2；
Fig. 4 is the top view of Fig. 2.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
The attached endoscopic procedure portion shown in Fig. 4 A-frame of attached drawing 2-, including the first stabilizer blade 2, the second stabilizer blade 3 and third branch
The upper surface of foot 4, first stabilizer blade 2, the second stabilizer blade 3 and third stabilizer blade 4 is connected by joint face 1, first stabilizer blade 2,
The lower end surface of two stabilizer blades 3 and third stabilizer blade 4 is generally aligned in the same plane, and the lower end of the first stabilizer blade 2, the second stabilizer blade 3 and third stabilizer blade 4
Equal outward flanging forms trunnion.The joint face 1 is arc top upward arc-shaped, the present embodiment be preferably it is hollow cylindric,
The side of the joint face 1 is connect with the upper end of first stabilizer blade 2, the other side of the joint face 1 and second stabilizer blade 3 and the
The upper end of three stabilizer blades 4 connects.
From fig. 4, it can be seen that the width of the first stabilizer blade 2, the second stabilizer blade 3 and third stabilizer blade 4 is respectively less than the joint face 1
Width.First stabilizer blade 2 and the second stabilizer blade 3 are symmetricly set on the two sides of joint face 1, and first stabilizer blade 2 and the second stabilizer blade 3 and institute
One of end face of joint face 1 is stated, mutual angled setting between the second stabilizer blade 3 and third stabilizer blade 4.The joint face 1
It is plane close to one end end face of the first stabilizer blade 2 and the second stabilizer blade 3, the other end face is cambered surface.
First through hole 20, are respectively arranged on the trunnion of 4 lower end of first stabilizer blade 2, the second stabilizer blade 3 and third stabilizer blade
Two through-holes 30 and third through-hole 40.By these three screw counter sinks can by screw by A-frame with outsole inside operation portion
Plate connection.Screw counter sink 10 there are four being symmetrical arranged on the joint face 1, can pass through screw by this four screw counter sinks
