Description

Endoscope head and endoscope capable of eliminating sterilization dead angle

This application claims priority to Chinese Patent Application No. 200910069834.1, entitled "Endoscope Head and Endoscope for Eliminating Disinfection Angles", filed on February 8, 2017. The content is incorporated herein by reference.

Technical field

The present invention relates to the field of medical devices, and more particularly to a headstock for guiding a surgical instrument on an endoscope and an endoscope to which the headstock is applied.

Background technique

With the development of technology, endoscopes are increasingly used in the diagnosis and treatment of diseases. The endoscope has a head seat that protrudes into the interior of the human body and functions to guide the surgical instrument and the camera. In some endoscopes, in order to dispose of the desired position in the subject, it is necessary to change the direction of the surgical instrument at the endoscope head. To achieve this, the endoscope head includes a support and a lifter. The support is provided with an instrument passage for the surgical instrument to pass through, and the lift clamp is placed at the outlet of the instrument passage, and is connected to the support through a rotating shaft. The surgical instrument is placed on the lifter after extending from the instrument channel. When the lifter is rotated by the external force, the surgical instrument can be rotated to adjust the direction of the lead.

As a mainstream structure of the current headstock, the lift clamp is placed in a cavity on the support, the periphery of the cavity is closed, and only the opening for lifting the lifter is left at the top, and the opening is also available The disinfectant is injected to disinfect the inside of the holder. However, this structure is easy to produce a disinfection dead angle. Especially for the space under the lifter, the disinfectant is difficult to enter the space due to the blocking action of the lifter. The disinfectant in the space will also be retained, resulting in incomplete disinfection and pollution, so there is an urgent need for an endoscope that can eliminate the dead angle of disinfection.

Summary of the invention

In order to overcome the deficiencies of the prior art, the present invention provides an endoscope head that can eliminate the dead angle of disinfection, so as to solve the problem that the disinfectant in the prior art is difficult to disinfect the inside of the cavity.

As a further improvement of the above solution, the liquid inlet and the liquid outlet are respectively located at both ends of the cavity.

As a further improvement of the above scheme, the liquid inlet and the liquid outlet are diagonally distributed.

As a further improvement of the above solution, at least two liquid inlets and a liquid outlet corresponding to the liquid inlet are provided, and the liquid inlets are oppositely disposed.

As a further improvement of the above solution, the liquid outlet is located on the side wall below the lift clamp.

As a further improvement of the above solution, a plurality of liquid outlets are provided on the side wall.

As a further improvement of the above aspect, the plurality of liquid outlets are distributed along the length direction of the cavity.

As a further improvement of the above solution, the plurality of liquid outlets are distributed along the circumferential direction of the cavity.

An endoscope that eliminates dead spots, including the endoscope head described above.

The beneficial effects of the invention are:

The disinfectant can be directly injected into the cavity from the inlet port, and the cavity is cleaned and disinfected before being discharged from the outlet port, so that the disinfection dead angle can be avoided, and the disinfectant can be prevented from staying inside the cavity, and the structure is simple and easy to popularize. achieve.

detailed description

The concept, specific structure and technical effect of the present invention will be described below with reference to the embodiments and the accompanying drawings. A clear and complete description is made to fully understand the objects, aspects and effects of the present invention. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

It should be noted that, unless otherwise stated, when a feature is referred to as “fixed” or “connected” in another feature, it may be directly fixed, connected to another feature, or indirectly fixed and connected to another feature. A feature. Further, the descriptions of the upper, lower, left, right, and the like used in the present invention are merely relative to the mutual positional relationship of the respective components of the present invention in the drawings.

Moreover, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art, unless otherwise defined. The terminology used in the description herein is for the purpose of description The term "and/or" used herein includes any combination of one or more of the associated listed items.

Referring to Figures 1 and 2, there are shown perspective views of different embodiments of the first embodiment of the endoscope head according to the present invention. As shown, the endoscope head includes an elevator clamp 100 and a front cover 200. The support, the lift clamp 100 is located in a cavity not shown on the support, the front cover 200 is wrapped on the outer side of the support, and only the upper corresponding cavity is provided with an opening for lifting the clamp, and the disinfectant is also The opening can be filled in to sterilize the internal structure of the support. However, due to the blockage of the lifter 100, it is difficult for the disinfectant to enter the interior of the cavity, especially in the space below the lifter, thereby causing a disinfection dead angle. Based on this, the present invention is provided with a liquid outlet 101 and a liquid inlet (not shown) on the side wall surrounding the cavity, and the disinfectant can be directly injected into the cavity from the inlet, and the cavity is cleaned and disinfected. It is discharged from the liquid outlet, so that the disinfection dead angle can be avoided, and the disinfectant can be prevented from staying inside the cavity.

Specifically, referring to FIG. 3, a cross-sectional view of an embodiment of the present invention is shown. As shown, the interior of the holder 300 is provided with a cavity 102, and the periphery of the cavity 102 is closed, and only the upper lifting clamp is left. The opening of the device 100 is provided with a liquid outlet 101 and a liquid inlet 103 on the side wall surrounding the cavity.

In this embodiment, the liquid outlet 101 and the liquid inlet 103 are respectively disposed at both ends of the cavity 102 along the length direction of the cavity 102. Further, the liquid outlet 101 is disposed at the front end of the cavity 102 (ie, the right end in the figure) The liquid inlet 103 is disposed at the rear end of the cavity 102 (ie, the left end in the drawing), and communicates with the disinfectant passage 104, so as to ensure that the disinfectant can flow through the entire cavity.
