Abstract
The present invention discloses a kind of head end part of endoscope, and comprising head end part body, the side of head end part body is used to insert human body, and opposite side is used to connect with coiled pipe, and head end part body is provided with pincers road pore, lighting fiber hole and image transmission optical fibre hole vertically；The head end part body is Elliptic Cylinder, and the outer wall of head end part body is provided with vertically to be used to weld the deep-slotted chip breaker for turning to steel wire, and deep-slotted chip breaker is located at the connecting side of head end part body；Relative to right cylinder, on the premise of the head end part is constant in each working hole aperture, the external diameter of head end part body reduces, so as to reduce face size so that the coiled pipe size subsequently coordinated can also diminish, beneficial to operation technique；And Elliptic Cylinder causes after same location distribution opens up each working hole, wall thickness increase, difficulty of processing is reduced.
Description
Technical field
The present invention relates to technical field of medical instruments, the head end part of specifically a kind of endoscope.
Background technology
Endoscope is that one kind has concentrated traditional optical, ergonomics, precision optical machinery, hyundai electronicses, mathematics, software to be equal to
The detecting instrument of one.Using endoscope it can be seen that the lesion that X ray can not be shown, therefore it is highly useful to doctor.It is interior
The head end part of sight glass, which has, sets the functions such as object lens, connection optical fiber and pincers deferent, is the important component of endoscope.
At present, head end part is generally cylinder, and the working hole of various different purposes is opened up on cylinder, and this structure can be made
External diameter into head end part is larger, then the coiled pipe external diameter being attached thereto is also just corresponding larger, is unfavorable for operation technique；And perforate
The wall thickness of cylinder is very thin afterwards, and difficulty of processing is larger.
The content of the invention
It is an object of the invention to provide a kind of head end part of endoscope, the head end part are constant in each working hole aperture
Under the premise of, face size can be reduced, reduce difficulty of processing.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of head end part of endoscope, comprising head end part body, the side of head end part body is used to insert human body, and opposite side is used for
Connected with coiled pipe, head end part body is provided with pincers road pore, lighting fiber hole and image transmission optical fibre hole vertically；The head end part body
For Elliptic Cylinder, the outer wall of head end part body is provided with vertically to be used to weld the deep-slotted chip breaker for turning to steel wire, and deep-slotted chip breaker is located at head end
The connecting side of part body.
Further, road pore is clamped, the insertion side in lighting fiber hole and image transmission optical fibre hole is respectively equipped with orifice chamfer.
Further, the head end part body insertion side is provided with two symmetrical scarves vertically, makes head end part
The end face of body insertion side is in cam shape；The end face edge of head end part body insertion side is provided with chamfering.
Further, the pincers road pore is stepped hole, and stepped hole insertion lateral aperture is less than connection lateral aperture.
Further, the image transmission optical fibre hole is also stepped hole, and stepped hole insertion lateral aperture is more than connection lateral aperture.
The beneficial effects of the invention are as follows：
First, head end part body is arranged to Elliptic Cylinder, it is constant in each working hole aperture relative to right cylinder, the head end part
On the premise of, the external diameter of head end part body reduces, so as to reduce face size so that the coiled pipe size subsequently coordinated also can
Diminish, beneficial to operation technique；And Elliptic Cylinder causes after same location distribution opens up each working hole, wall thickness increase, reduce
Difficulty of processing；
2nd, by deep-slotted chip breaker can make steering steel wire directly with head end part body weld, compared to normal welding on snake bone energy
Preferably control head end part turns to；In addition, without on snake bone clamping ring processing wear the hole of steel wire, reduce the difficulty for wearing steel wire
Degree, reduce processing cost；
3rd, the orifice chamfer for clamping road pore is easy to clamp water outlet and the backwater of deferent；The aperture in lighting fiber hole and image transmission optical fibre hole
Chamfering is easy to optic fibre light path smooth；
4th, the chamfering of scarf and head end part body insertion side end face edge, makes head end part in human urethra, ureter and kidney
The smooth mobile and rotation of intracavitary, reduces the damage to mucous membrane.
