Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a multifunctional gallbladder-preserving and stone-removing hard endoscope. Background Art

[0002] Laparoscope is a commonly used instrument in hepatobiliary surgery. Its function is to extend into the patient's closed abdominal cavity to collect images in real time and transmit them to the display device, thereby guiding the doctor to operate relevant surgical instruments outside the abdomen to complete the exploration of the surgical site, tissue separation and incision, stone removal and other operations. However, the existing laparoscope has a single function and only has the exploration function. When performing stone removal operations, a guide tube must be inserted into the surgical site and then the stone removal basket must be inserted. When flushing, a flushing tube must also be inserted separately. The doctor has to switch between multiple different instruments, which is inconvenient for the doctor to operate and leads to longer operation time. Utility Model Content

[0003] The embodiment of the present application provides a multifunctional cholecystolithotomy hard endoscope, which is used to solve the problem that the existing laparoscope has a single function and multiple surgical instruments need to be repeatedly switched.

[0004] In order to achieve the above purpose, the embodiment of the present application adopts the following technical solution:

[0005] The embodiment of the present application provides a multifunctional gallbladder-preserving and stone-removing hard endoscope, including a endoscope body assembly, a handle, a camera, and a lighting lamp head.

[0006] The mirror body assembly has a first end and a second end, and a main channel, a first branch channel and a second branch channel are provided in the mirror body assembly. The outlet of the first branch channel and the outlet of the second branch channel are both connected to the entrance of the main channel, and the outlet of the main channel is located at the first end of the mirror body assembly, and the entrances of the first branch channel and the second branch channel are both located at the second end of the mirror body assembly. One end of the handle is connected to the side wall of the mirror body assembly, and the other end of the handle is provided with a transmission connector. The camera is provided at the first end of the mirror body assembly, and the camera is connected to the transmission connector through a cable buried in the mirror body assembly. The lighting lamp head is provided at the first end of the mirror body assembly, and a fiber optic connector is provided on the side wall of the mirror body assembly, and the lighting lamp head is connected to the fiber optic connector through an optical fiber buried in the mirror body assembly.

[0007] The present application provides a multifunctional gallbladder-preserving and stone-removing hard endoscope. After the first end of the mirror body assembly is inserted into the patient's abdominal cavity, the doctor can use the camera and the lighting lamp head to cooperate (the camera needs to be connected to an external image display device through a transmission connector, and the lighting lamp head needs to be connected to an external light source through an optical fiber connector) to observe the surgical site. In addition, a main channel, a first branch channel, and a second branch channel are also set in the mirror body assembly, and the outlet of the first branch channel and the outlet of the second branch channel are both connected to the entrance of the main channel, and the outlet of the main channel is located at the first end of the mirror body assembly, and the entrance of the first branch channel and the second branch channel are both located at the second end of the mirror body assembly. During the operation, the surgical site is flushed or the liquid is sucked out through the first branch channel and the main channel, and the stone-removing net basket can also be extended into the patient's body through the second branch channel and the main channel to remove the stones, so there is no need to repeatedly switch surgical instruments with single functions, which greatly facilitates the doctor's operation and helps to shorten the operation time.

[0008] In another possible implementation, the mirror body assembly includes a hard mirror body and a guide rod, the guide rod is fixed to one end of the hard mirror body, the end of the guide rod away from the hard mirror body is the first end, and the end of the hard mirror body away from the guide rod is the second end. The grip and the optical fiber connector are both arranged on the side wall of the hard mirror body. In this way, the entrance of the first branch channel, the entrance of the second branch channel, the transmission connector, and the optical fiber connector are respectively dispersed around the hard mirror body, so that when extending into the stone extraction net basket, docking the flushing and suction component, docking the image display device, and docking the light source, there is enough working space without mutual interference.

[0009] In another possible implementation, a funnel is provided at the entrance of the second branch channel, so that the funnel can play a certain guiding role, making it easier for the stone-taking basket to be inserted from the entrance of the second branch channel.

[0010] In another possible implementation, an adapter is provided at the entrance of the first branch channel, so that the adapter facilitates the docking of the flushing and suction assembly with the first branch channel.

[0011] In another possible implementation, the multifunctional gallbladder-preserving and stone-removing hard endoscope further includes a flushing and suction component, which is connected to the adapter through a hose. In this way, by docking the flushing and suction component with the adapter at the entrance of the first branch channel, the flushing and suction component can then be used to flush or remove liquid from the surgical site of the patient.

[0012] In another possible implementation, the flushing and suction assembly includes a liquid storage bottle and a balloon, the liquid storage bottle is provided with a first interface and a second interface, the first interface is connected to the balloon, and the second interface is connected to the adapter through a hose. In this way, when flushing is required, the flushing liquid in the liquid storage bottle can be squeezed out from the second interface by pressing the balloon, and the flushing liquid is then sprayed out from the first end of the mirror body assembly through the first branch channel and the main channel, thereby flushing the surgical site. When suction is required, the pressure applied to the balloon is removed, and when the balloon gradually returns to its original state under the action of its own elastic force, the liquid in the surgical site of the patient and some smaller stones will be sucked into the main channel under the action of atmospheric pressure, and then flow to the liquid storage bottle through the first branch channel.

[0013] In another possible implementation, the liquid storage bottle includes a first bottle body, a second bottle body and a transfer tube, the first bottle body and the second bottle body are connected through the transfer tube, and the radius of the first bottle body and the radius of the second bottle body are both greater than the diameter of the transfer tube, and the first interface and the second interface are both arranged on the first bottle body. In this way, the stones attracted into the liquid storage bottle will fall into the second bottle body under the action of gravity, and because the diameter of the transfer tube is much smaller than the diameter of the first bottle body / the second bottle body, that is, the liquid storage bottle is in the shape of a gourd, when the balloon is pressed again to squeeze out the flushing liquid in the liquid storage bottle, and because the first interface and the second interface are both arranged on the first bottle body, the flushing liquid in the first bottle body and the balloon is mainly squeezed out, thereby reducing the risk that the stones in the second bottle body are carried out by the water flow and enter the patient's body again with the flushing liquid.

[0014] In another possible implementation, the liquid storage bottle is made of a transparent material, so that the doctor can observe the remaining amount of flushing liquid in the liquid storage bottle and the number of stones sucked out.

[0015] In another possible implementation, the diameter of the guide rod is 8 mm-10 mm. Thus, the diameter of the guide rod is smaller, and the corresponding wound formed on the patient's body is also smaller.

[0016] In another possible implementation, the diameter of the main channel is 3 mm to 6 mm. With this arrangement, the flushing and suction assembly can also be used to suck out smaller stones from the patient's body through the main channel. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present application embodiment provides a multifunctional gallbladder-preserving and stone-removing hard endoscope 01, see Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a schematic diagram of the overall structure of a multifunctional gallbladder-preserving and stone-removing hard endoscope 01 provided in an embodiment of the present application. Figure 2 for Figure 1 A partial enlarged view of point A in the middle. Figure 3 for Figure 1 A cross-sectional view of the internal structure of the multifunctional gallbladder-preserving and stone-removing hard endoscope 01.

[0030] The multifunctional gallbladder-preserving and stone-removing hard endoscope 01 comprises a lens body assembly 10 , a handle 20 , a camera 30 and a lighting lamp head 50 .

[0031] The mirror body assembly 10 has a first end 10a and a second end 10b. The mirror body assembly 10 is provided with a main channel 300, a first branch channel 100 and a second branch channel 200. The outlet of the first branch channel 100 and the outlet of the second branch channel 200 are both connected to the entrance of the main channel 300. The outlet of the main channel 300 is located at the first end 10a of the mirror body assembly 10, and the entrances of the first branch channel 100 and the second branch channel 200 are both located at the second end 10b of the mirror body assembly 10. One end of the grip 20 is connected to the side wall of the mirror body assembly 10, and the other end of the grip 20 is provided with a transmission connector 40. The camera 30 is provided at the first end 10a of the mirror body assembly 10, and the camera 30 is connected to the transmission connector 40 through a cable buried in the mirror body assembly 10. The lighting lamp head 50 is provided at the first end 10a of the mirror body assembly 10, and an optical fiber connector 60 is provided on the side wall of the mirror body assembly 10. The lighting lamp head 50 is connected to the optical fiber connector 60 through an optical fiber buried in the mirror body assembly 10.

[0032] In this way, with the multifunctional gallbladder-preserving and stone-removing hard endoscope 01 provided in the present application, after the first end 10a of the mirror body assembly 10 is inserted into the patient's abdominal cavity, the doctor can use the camera 30 and the lighting lamp head 50 in combination (the camera 30 needs to be connected to an external image display device through the transmission connector 40, and the lighting lamp head 50 needs to be connected to an external light source through the optical fiber connector 60) to observe the surgical site.

[0033] In addition, a main channel 300, a first branch channel 100, and a second branch channel 200 are provided in the mirror body assembly 10, and the outlet of the first branch channel 100 and the outlet of the second branch channel 200 are both connected to the entrance of the main channel 300, the outlet of the main channel 300 is located at the first end 10a of the mirror body assembly 10, and the entrances of the first branch channel 100 and the second branch channel 200 are both located at the second end 10b of the mirror body assembly 10. During the operation, the surgical site can be flushed or the liquid can be sucked out through the first branch channel 100 and the main channel 300, and the stone removal basket can also be inserted into the patient's body through the second branch channel 200 and the main channel 300 to remove the stones, thereby eliminating the need to repeatedly switch surgical instruments with a single function, greatly facilitating the doctor's operation and helping to shorten the operation time.

[0034] Furthermore, the mirror body assembly 10 includes a hard mirror body 11 and a guide rod 12, the guide rod 12 is fixed to one end of the hard mirror body 11, the end of the guide rod 12 away from the hard mirror body 11 is a first end 10a, and the end of the hard mirror body 11 away from the guide rod 12 is a second end 10b. The handle 20 and the optical fiber connector 60 are both arranged on the side wall of the hard mirror body 11.

[0035] In this way, the entrance of the first branch channel 100, the entrance of the second branch channel 200, the transmission connector 40, and the optical fiber connector 60 are respectively dispersedly arranged around the hard mirror body 11, so that when inserting the stone removal basket, docking the flushing and suction component 90, docking the image display device, and docking the light source, there is enough working space without mutual interference.

[0036] In some embodiments, the diameter of the guide rod 12 is 8 mm-10 mm, for example, the diameter of the guide rod 12 is 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, etc. Thus, the diameter of the guide rod 12 is smaller, and accordingly, the wound formed on the patient's body is also smaller.

[0037] In some embodiments, see Figure 4 As shown, Figure 4 The overall structure diagram of another multifunctional gallbladder-preserving and stone-removing hard endoscope 01 provided in the embodiment of the present application is shown in FIG. A funnel 70 is provided at the entrance of the second branch channel 200. In this way, the funnel 70 can play a certain guiding role, facilitating the insertion of the stone-removing basket from the entrance of the second branch channel 200.

[0038] For further information, please see Figure 4 As shown, an adapter 80 is provided at the entrance of the first branch channel 100. In this way, the adapter 80 facilitates the docking of the flushing and suction component 90 and the first branch channel 100.

[0039] On the basis of the above, see Figure 5As shown, Figure 5 The overall structural diagram of another multifunctional gallbladder-preserving and lithotripsy hard endoscope 01 provided in the embodiment of the present application. The multifunctional gallbladder-preserving and lithotripsy hard endoscope 01 further includes a flushing and suction component 90, which is connected to the adapter 80 through a hose 93. In this way, by docking the flushing and suction component 90 with the adapter 80 at the entrance of the first branch channel 100, the flushing and suction component 90 can then be used to flush or remove liquid from the surgical site of the patient.

[0040] Further, the diameter of the main channel 300 is 3 mm-6 mm, for example, the diameter of the main channel 300 is 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, etc. Thus, when the flushing and suction assembly 90 is used, smaller stones (for example, stones with a maximum diameter less than 3 mm) can also be sucked out of the patient's body through the main channel 300.

[0041] In some embodiments, see Figure 5 As shown, the flushing and suction assembly 90 includes a liquid storage bottle 91 and a balloon 92 . The liquid storage bottle 91 is provided with a first interface 91a and a second interface 91b . The first interface 91a is connected to the balloon 92 , and the second interface 91b is connected to the adapter 80 through a hose 93 .

[0042] Thus, when flushing is required, by pressing the balloon 92, the volume of the balloon 92 is reduced, and the flushing liquid in the liquid storage bottle 91 and the balloon 92 can be squeezed out from the second interface 91b, and the flushing liquid is then ejected from the first end 10a of the mirror body assembly 10 through the first branch channel 100 and the main channel 300, thereby flushing the surgical site. When suction is required, the pressure applied to the balloon 92 is removed, and the balloon 92 gradually returns to its original state under the action of its own elastic force, and the liquid in the surgical site of the patient and some small stones are sucked into the main channel 300 under the action of atmospheric pressure, and then flow into the liquid storage bottle 91 through the first branch channel 100.

[0043] It is understandable that the balloon 92 may be made of a flexible material such as rubber or silicone that can produce elastic deformation, and the present application does not impose any special limitation on this.

[0044] Furthermore, the liquid storage bottle 91 is made of a transparent material, such as glass, plastic, etc., so that the doctor can observe the remaining amount of flushing liquid in the liquid storage bottle 91 and the number of stones sucked out.

[0045] For further information, see Figure 6 As shown, Figure 6A partial cross-sectional view of a flushing and suction assembly 90 provided in an embodiment of the present application. The liquid storage bottle 91 includes a first bottle body 911, a second bottle body 912 and a transfer tube 913. The first bottle body 911 and the second bottle body 912 are connected through the transfer tube 913. The radius of the first bottle body 911 and the radius of the second bottle body 912 are both greater than the diameter of the transfer tube 913. The first interface 91a and the second interface 91b are both provided on the first bottle body 911.

[0046] In this way, the stones attracted into the liquid storage bottle 91 will fall into the second bottle body 912 under the action of gravity. Since the diameter of the transfer tube 913 is much smaller than the diameter of the first bottle body 911 / the second bottle body 912, that is, the liquid storage bottle 91 is gourd-shaped, when the balloon 92 is pressed again to squeeze out the flushing liquid in the liquid storage bottle 91, since the first interface 91a and the second interface 91b are both arranged on the first bottle body 911, the flushing liquid located in the first bottle body 911 and the balloon 92 is mainly squeezed out, thereby reducing the risk of the stones in the second bottle body 912 being carried out by the water flow and entering the patient's body with the flushing liquid.

[0047] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0048] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
