Detailed Description

The present application will be described in further detail with reference to the following detailed description and accompanying drawings. Wherein like elements in different embodiments have been given like element numbers associated therewith. In the following description, numerous details are set forth in order to provide a better understanding of the present application. However, those skilled in the art will readily recognize that some of the features may be omitted or replaced with other elements, materials, methods in different instances. In some instances, certain operations related to the present application have not been shown or described in detail in order to avoid obscuring the core of the present application from excessive description, and it is not necessary for those skilled in the art to describe these operations in detail, so that they may be fully understood from the description in the specification and the general knowledge in the art.

Furthermore, the features, operations, or characteristics described in the specification may be combined in any suitable manner to form various embodiments. Also, the various steps or actions in the method descriptions may be transposed or transposed in order, as will be apparent to one of ordinary skill in the art. Thus, the various sequences in the specification and drawings are for the purpose of describing certain embodiments only and are not intended to imply a required sequence unless otherwise indicated where such sequence must be followed.

The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).

At present, a conventional aspirator is not provided with a visualization device, so that a doctor needs to check the condition in deep tissues in a mode of naked eye identification, and when the doctor checks specific conditions by himself, the doctor needs to check the conditions in a close range. The adoption of the eye recognition method is inconvenient to operate and not necessarily capable of acquiring a precise field of view. For example, in some cases requiring microscopic magnification, the doctor may need to lean or lower his head, and bend over, and maintain the posture for a long time, which may cause fatigue of the limbs, thereby affecting the fine operation of the doctor. On the other hand, when the doctor approaches the exposed deep tissue of the human body, there is a risk that foreign matter falls onto the deep tissue, possibly causing additional infection of the deep tissue.

Meanwhile, the conventional suction apparatus adopted at present can be repeatedly used. After the suction apparatus is used each time, cleaning and disinfection are needed, which not only increases the workload of clinical decontamination, but also may cause the problem of cross infection due to the reasons of incomplete cleaning of dirt in the suction tube lumen, etc. If design visual equipment on this traditional aspirator, still can further increase the disinfection degree of difficulty because of including movie & TV collection electronic component such as camera, further increase cross infection's risk.

Therefore, the disposable visual aspirator with the visual effect is designed to provide certain convenience for doctors, so that the safety of the operation is improved, and the operation quality and the postoperative recovery of the patient are better guaranteed. The scheme of the disposable visual aspirator designed by the application is introduced as follows:

as shown in fig. 1, a disposable visual attractor, comprising: a suction tube 1 and a visualization mechanism.

One end of the suction tube 1 is a suction end 11, and the other end is a negative pressure suction connection end 12.

By adopting the disposable visual suction apparatus, the visual field collector 3 of the visual mechanism timely acquires the visual field of the operation, the acquired operation visual field is sent to the image processing display 5 through the visual field connecting line 2, and the image processing display 5 plays the operation visual field in real time, so that a doctor can conveniently acquire the operation visual field condition in real time. The image processing display 5 can display the operation visual field in a high-definition mode, for example, the conditions of deep brain tissue structures, bleeding point positions and the like in a high-definition mode, accurate positioning, efficient attraction and damage reduction can be achieved, and smooth operation and life safety of a patient can be guaranteed. Through design visual mechanism on the aspirator, realized that the suction operation process is visual, the accessible place of suction tube 1 is all visible, has avoided the visual field of observation angle and the degree of depth that people's naked eye brought to be restricted problem. The help attracts the operation to realize accurate location to accomplish and effectively clear away various hydrops or tumor tissue, and can reduce the blind problem of inhaling the tissue damage that the operation caused, still be favorable to observing the position of looking for slight bleeding point, do benefit to accurate hemostasis. Wherein partial structure between visual mechanism's the video connecting wire both ends is fixed with attracting pipe 1 is integrative, and field of vision collector 3 is fixed and is attracted end 11 one side on attracting pipe 1, and the doctor of being convenient for holds the disposable visual aspirator of use with one hand, and the operation is simple and easy, the aspirator operation burden that does not additionally increase. And the visual aspirator is disposable product, and then can be thrown away after using, does not have the used repeatedly problem, also can not have the problem that washing, disinfection do not thoroughly lead to cross infection from the root, avoids used repeatedly to lead to cross infection's risk because of the disinfection problem, better guarantee patient's operation safety nature. The disposable visual suction apparatus designed by the application has the advantages of providing clear operation visual field for doctors, reducing the risk of cross infection of the suction apparatus and being low in cost, and when the suction apparatus is used each time, the new suction apparatus is respectively connected with the corresponding negative pressure apparatus and the image processing display 5, so that the suction apparatus can be put into use.

Preferably, the visualization mechanism further comprises at least one light source 4, and the light source 4 and the field collector 3 are located at the same end of the field connecting line 2. One end of the visual field connecting line 2 is respectively connected with the visual field collector 3 and the light source 4, and the other end is used for being connected with the image processing display 5. The light source 4 is arranged, so that a brighter visual field environment can be provided for the visual field collector 3, the visual field collector 3 can conveniently obtain a clearer visual field, or the processing difficulty of the image processing display 5 is reduced. Wherein, the light source 4 is an LED light source, and the suction tube 1 is made of medical polymer materials, softer plastics, even metal materials and the like. When the suction tube 1 is made of a metal material, the shape of the suction tube 1 can be conveniently shaped, but the cost is relatively high.

As shown in fig. 2-4, the visualization mechanism further comprises an installation body 6, the field of view collector 3 and 1-4 light sources 4 are embedded in the installation body 6, and the installation body 6 is fixed on one side of the suction end 11 of the suction tube 1. Specifically, as shown in fig. 2, the mounting body 6 is a block-shaped mounting body, the mounting body 6 is provided with a first mounting hole 61 and at least one second mounting hole 62, and the number of the second mounting holes 62 is the same as the number of the light sources 4. When the number of the light sources 4 is plural, for example, 2, the two light sources 4 are symmetrically and uniformly distributed on the peripheral side of the field of view finder 3, so as to provide a sufficiently bright field of view gathering environment for the field of view finder 3.

The suction tube 1 is generally a cylindrical tube body, and a curved groove corresponding to the curved surface on the peripheral side of the suction tube 1 is formed in the corresponding mounting body 6, so that the mounting body 6 is fixed on one side of the suction tube 1 close to the suction end 11, and the radial size of the position of the disposable visual suction apparatus can be reduced. Meanwhile, the visual field collector 3 and the light source 4 are fixed inside the mounting body 6 in an embedded mode, and the radial size of the disposable visual aspirator at the position where the mounting body 6 is fixed can also be effectively reduced. Adopt this structural design's disposable visual aspirator, can accomplish to be less with the radial dimension that sets up the disposable visual aspirator of installation body 6 department to use the disposable visual aspirator to comparatively accurate operation, perhaps use the disposable visual aspirator of this application on narrow and small operation space. For example, the suction tube 1 of the present application has an outer diameter of 3-4mm, the radial width of the mounting body 6 is 2-3mm, and the corresponding radial dimension of the disposable visual suction device at the position where the mounting body 6 is arranged is about 5mm.

The number of the light sources 4 should not be too many, for example, when the number of the light sources 4 is too many, the lighting environment far exceeding the requirement causes the waste of resources, and for example, when the number of the light sources 4 is too many, the radial size of the installation body 6 can be inevitably increased, and then the radial size of the disposable visual suction apparatus at the fixed installation body 6 can be increased, which is not beneficial to applying the disposable visual suction apparatus to a more precise operation or a narrow space operation. Therefore, the number of the light sources 4 is set to be 1-4 in comprehensive consideration, so as to better consider the lighting requirement and the radial size requirement of the disposable visual suction apparatus.
