Detailed Description
The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
Referring to fig. 1 to 3, fig. 1 is a front view schematically illustrating an embodiment of the detachable endoscopic access bag of the present invention. Fig. 2 is a schematic sectional view of an embodiment of the detachable endoscopic object bag of the present invention. Fig. 3 is a schematic side view of an embodiment of the detachable endoscopic access bag of the present invention. The utility model provides a separable endoscope gets thing bag 10, it includes: the device comprises a sleeve 1, a pull rod 2, a connecting rod 3, a connecting piece 4, a positioning pin 5, a sleeve handle 6, a pull rod fixing sleeve 7, a pull rod handle 8 and a bag 9.
The pull rod 2 is movably inserted in the sleeve 1 back and forth. The connecting rod 3 is inserted in the pull rod 2. The connecting piece 4 is movably connected with the front end of the connecting rod 3. A positioning pin 5 is provided on the pull rod 2 for cooperation with the connecting piece 4. The cannula handle 6 is mounted on the outer circumference of the cannula 1. The pull rod fixing sleeve 7 is combined with the rear end of the pull rod 2. A drawbar handle 8 is rotatably mounted at the rear of the drawbar fixing sleeve 7 and is connected to the rear end of the connecting rod 3, which protrudes rearward from the rear end of the drawbar 2. The object obtaining bag 9 is connected with the connecting piece 4.
The bag 9 includes a bag body 91 and an elastic body 92. Wherein the elastic body 92 is connected to the connecting member 4. In this embodiment, the connecting member 4 is screwed to the front end of the connecting rod 3. For example, the front end of the connecting rod 3 is provided with an external thread, and the connecting member 4 is provided with an internal thread.
It will be appreciated that in other embodiments, the connecting member 4 may be connected to the front end of the connecting rod 3 by other means, such as: a snap connection is also possible. For example: a clamping groove is arranged on the connecting piece 4, and a buckle matched with the clamping groove is arranged at the front end of the connecting rod 3.
The working principle of the separation endoscope object-taking bag 10 of the utility model substantially comprises:
in an initial state, that is, after the detachable endoscopic access bag 10 is manufactured and before it is put into use, the access bag 9 is stored in the sleeve 1 folded, the connecting member 4 is connected to the front end of the connecting rod 3, and the front end of the connecting rod 3 is located at a position rearward relative to the pull rod 2.
In the use state, firstly, the detachable endoscope object fetching bag 10 is inserted into a set position in the body; then, operating the pull rod handle 8 and/or the pull rod fixing sleeve 7 (for example, holding the sleeve handle 6 with one hand and pushing the pull rod handle 8 with the other hand), and pushing the pull rod 2 (together with the connecting rod 3, the connecting piece 4, the positioning pin 5 and the bag taking 9) forward until the front end of the pull rod 2 is pushed to a set position, at this time, the bag taking 9 extends out of the front end of the sleeve 1, and the elastic body 92 is opened, so that the bag body 91 is opened together, and a sample can be taken;
then, after taking a sample, operating the pull rod handle 8 and/or the pull rod fixing sleeve 7 (for example, one hand holds the sleeve handle 6, the other hand pulls the pull rod handle 8), and pulling the pull rod 2 back until the pull rod is pulled back to another set position, wherein the elastic body 92 of the object taking bag 9 is partially retracted into the sleeve 1, the elastic body 92 is folded, so that the bag body 91 is folded together, and the detachable endoscope object taking bag 10 can be pulled out from the body;
finally, when the object fetching bag 9 needs to be taken down, the pull rod bracelet 8 can be operated (for example, the pull rod fixing sleeve 7 is held by one hand, the pull rod bracelet 8 is rotated anticlockwise by the other hand), so that the front end of the connecting rod 3 is withdrawn from the connection (for example, threaded connection) with the connecting piece 4, the object fetching bag 9 and the connecting piece 4 can be separated from other structures together, and therefore a sample can be conveniently taken out from the object fetching bag 9 for subsequent detection and analysis.
The connecting piece 4 and the pull rod 2 can be positioned relatively. In the present embodiment, the relative positioning between the connecting member 4 and the pull rod 2 is realized by the cooperation between a positioning pin 5 (for example, the positioning pin 5 is driven into the outer wall of the pull rod 2 and protrudes toward the hollow portion inside the pull rod 2) provided at a predetermined position on the front end of the pull rod 2 and a positioning groove 41 (provided outside the connecting member 4) on the connecting member 4. In other embodiments, a positioning groove may be provided on the inner side of the pull rod 2, and a positioning protrusion may be provided on the outer side of the connecting member 4.
When the object taking bag 9 needs to be taken down, the positioning pin 5 is located in the positioning groove 41, the pull rod bracelet 8 is rotated anticlockwise, and due to the matching relation between the positioning groove 41 on the connecting piece 4 and the positioning pin 5, the connecting piece 4 cannot rotate along with the anticlockwise rotation of the connecting rod 3 in the circumferential direction, so that the threaded connection between the front end of the connecting rod 3 and the connecting piece 4 can be disconnected. When the connecting piece 4 is disconnected from the front end of the connecting rod 3, the connecting piece 4 together with the fetching bag 9 connected with the connecting piece can be forwards pulled out from the front end of the pull rod 2, and further can be forwards pulled out from the front end of the sleeve 1.
Compared with the prior art, the utility model discloses a separable endoscope thing bag 10 of getting through setting up the connecting piece 4 that links to each other with the elastomer 92 of thing bag 9 ingeniously to make connecting piece 4 can 2 location pull rods relatively, the front end swing joint of connecting piece 4 and connecting rod 3 can make connecting piece 4 and get thing bag 9 break away from the front end of sleeve pipe 1, be favorable to getting the separation of thing bag 9 and body (other structures outside thing bag 9 and the connecting piece 4 promptly), thereby the sample is taken out from thing bag 9 to the convenience and subsequent detection and analysis are carried out.
It should be understood that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same, and those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some technical features; and that such modifications and substitutions are intended to be included within the scope of the appended claims.
