Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a surgical instrument with an elastic buckle structure. Background Art

[0002] Clinical in vivo examination and visual surgical treatment require endoscopes with clear images to help doctors improve the accuracy of diagnosis. Medical endoscopes are detection and treatment instruments that integrate optics, electricity, precision machinery, and software. They have image transmission components, optical or electronic imaging modules, cold light sources or LED electronic light sources, mechanical devices, etc. They can enter the body through natural channels. Endoscopes can be used to see lesions that cannot be displayed by X-rays and ultrasound. Therefore, they are very useful for improving medical quality. Many diseases need to be examined, diagnosed, and treated through endoscopes, such as diseases of the trachea, esophagus, stomach, intestines, and bladder. Most of the catheters and handles of electronic ureteroscopes in the prior art are connected by gluing and fixing, but this requires a high amount of glue and the gluing method during the assembly process. Otherwise, the glue stacking will cause the handle to be unable to buckle, and insufficient glue or uneven glue coating will cause the inserted catheter to be loosely fixed or even fall off.

[0003] For example, a Chinese invention patent application discloses an electronic ureteroscopic endoscope [application number: CN202110642611.6]. The invention application includes: the endoscope includes a camera sub-scope and a treatment sub-scope, the camera sub-scope and the treatment sub-scope can be interlocked, the insertion tubes of the camera sub-scope and the treatment sub-scope are both semi-tubular structures, the camera half-tube and the treatment half-tube can be interlocked, the lighting passage and the camera passage are arranged in the camera half-tube, and the working channel is arranged in the treatment half-tube.

[0004] Although this invention application has the advantage of being able to effectively save surgical time and avoid damage to human organs, it still fails to solve the above-mentioned problems. Utility Model Content

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1 As shown, a surgical instrument with an elastic snap-on structure comprises an outer shell 1, one end of the outer shell 1 is provided with a connecting portion 2, one end of a pipe 3 is connected to the connecting portion 2, a fixing component 4 is also provided in the connecting portion 2, one end of the pipe 3 extends into the connecting portion 2 and the fixing component 4 is pressed on the outside of the pipe 3.

[0024] When the utility model is used, one end of the pipe 3 is inserted into the connecting part 2, and then the fixing component 4 is assembled and pressed on the outer surface of the pipe 3 to fix the pipe 3, thereby ensuring that no glue is used in the entire installation process. Therefore, the utility model adopts a method of fixing the pipe 3 with the fixing component 4 to replace the gluing fixing method in the prior art, and no glue is required during the assembly process, thereby avoiding the problem that the traditional assembly process has high requirements on the amount of glue and the gluing method.

[0025] like Figure 2 As shown, the fixing assembly 4 includes a fixing seat 41 fixedly connected in the connecting portion 2, and the surface of the fixing seat 41 has an arc-shaped groove 42 adapted to the outer surface of the pipe 3. The fixing assembly 4 also includes a snap-fitting member 43 and a mounting screw 44 for fixing the snap-fitting member 43 on the fixing seat 41. The surface of one side of the pipe 3 is in contact with the arc-shaped groove 42, and the surface of the other side is pressed with a snap-fitting member 43.

[0026] Preferably, the buckle 43 is made of an elastic material. The utility model does not limit the specific type of the elastic material, and it can be an elastic material commonly used in the prior art, such as a rubber material or a silicone material.

[0027] The fastener 43 of the utility model is made of elastic material and is detachably connected to the fixing seat 41 by installing screws 44. In this way, after assembly, the position of the catheter 3 can still be fine-tuned, which has greater flexibility than the glue fixing method.

[0028] like Figure 3As shown, the clip 43 includes a fixedly connected mounting portion 431 and a clip portion 432, the mounting screw 44 is connected to the mounting portion 431, and an arc-shaped clip groove 433 is provided at the bottom of the clip portion 432, and the pipe 3 is embedded in the clip groove 433. The clip portion 432 is used to cooperate with the mounting screw 44 so that the clip 43 is fixed to the fixing seat 41 as a whole, and the mounting portion 431 is pressed on the outer surface of the pipe 3 to apply pressure to the pipe 3, so that the pipe 3 is fixed.

[0029] Preferably, the maximum width of the slot 433 is greater than the outer diameter of the pipe 3. This facilitates the pipe 3 to be inserted into the slot 433. Since the buckle 43 is made of elastic material, after assembly, the mounting portion 431 will be pressed against the pipe 3 and deformed to a certain extent, thereby improving the firmness of the installation of the pipe 3.

[0030] like Figure 3 As shown, the buckle parts 432 are provided with two and are symmetrically connected to both sides of the mounting part 431. The buckle part 432 is also provided with a mounting through hole 434 that penetrates the buckle part 432. The outer edge of the mounting through hole 434 is surrounded by a supporting platform 435. The supporting platform 435 is located below the upper surface of the buckle part 432. One end of the mounting screw 44 is pressed on the supporting platform 435, and the other end passes through the mounting through hole 434 and is connected to the fixing seat 41. The buckle part 432 is symmetrically arranged to ensure the uniformity of force distribution and further ensure the stability of the pipeline 3 after installation. The supporting platform 435 located below the upper surface of the buckle part 432 can ensure that the end of the mounting screw 44 will not protrude to the outside of the entire buckle 43 after assembly and affect the assembly of other parts.

[0031] Preferably, the axis center line of the slot 433 is parallel to the axis center line of the pipe 3. This ensures that the pipe 3 is subjected to uniform force after assembly.

[0032] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0033] Although the terms such as outer shell 1, connecting part 2, pipe 3, fixing assembly 4, fixing seat 41, arc groove 42, buckle 43, mounting screw 44, mounting part 431, buckle part 432, slot 433, mounting through hole 434, supporting platform 435 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
