Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and more specifically, it relates to a laparoscopic bile duct stone fragmentation and removal device. Background Technology

[0002] Currently, bile duct stones are a common and prevalent disease among adults in my country. They can lead to biliary obstruction, cholangitis, and even be life-threatening. With the rapid development of minimally invasive surgery, laparoscopic choledochotomy and choledochoscopy is now the main surgical method for treating bile duct stones.

[0003] Based on the above, the inventors have discovered the following problems: When connecting the existing bile duct stone removal device to the duodenoscope, most of them are tightened by threads. However, during use, medical staff may shake the device multiple times, which may cause the duodenoscope to fall off, indirectly causing inconvenience to medical staff.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a laparoscopic bile duct stone fragmentation and removal device in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose and effectiveness of this laparoscopic bile duct stone fragmentation and removal device are achieved through the following specific technical means:

[0006] A laparoscopic bile duct stone fragmentation and removal device includes an operating handle. A duodenoscope is connected and installed at one end of the operating handle. The operating handle has a mechanism for fixing the duodenoscope inside. A toggle is fixedly sleeved on the surface of the duodenoscope, and a biliary endoscope is installed inside the duodenoscope. A threaded hole is opened on one side of the operating handle, and a thread is provided at one end of the duodenoscope, which is then installed into the threaded hole via the thread. The mechanism for fixing the duodenoscope includes a connecting rod. A spring is sleeved on the surface of the connecting rod. A limit block is installed at one end of the connecting rod, and a locking block is installed at one end of the limit block. One end of the locking block extends through the operating handle into the threaded hole. A handle is installed at the top of the operating handle, and one end of the handle extends through the operating handle into the interior and connects to the connecting rod.

[0007] Furthermore, the surface of the thread has a groove, and the locking block is installed inside the groove.

[0008] Furthermore, sealing gaskets are provided at the contact points between the duodenoscope, choledochoscope and the operating handle.

[0009] Furthermore, an adjustment handle is provided on one side of the operating handle.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] By utilizing the interlocking mechanism between the locking block and the slot, the operator can first screw the duodenoscope into the threaded hole. While screwing, the operator can pull the handle to move the connecting rod, the limiting block, and the locking block. When the operator tightens the duodenoscope, the locking block will automatically engage with the slot under the action of the spring, thus further securing the duodenoscope. The operation is very simple, avoiding the possibility of the duodenoscope falling off after prolonged use. This indirectly improves the connection efficiency between the duodenoscope and the operating handle, and the design greatly increases practicality. Attached Figure Description

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 6 As shown:

[0025] This utility model provides a laparoscopic bile duct stone fragmentation and removal device, including an operating handle 1. A duodenoscope 3 is connected and installed at one end of the operating handle 1. The operating handle 1 has a mechanism for fixing the duodenoscope inside. A toggle element 2 is fixedly sleeved on the surface of the duodenoscope 3, and a cholangioscope 4 is installed inside the duodenoscope 3. A threaded hole 8 is opened on one side of the operating handle 1. A thread 5 is provided at one end of the duodenoscope 3, and the duodenoscope 3 is installed into the threaded hole 8 through the thread 5. The mechanism for fixing the duodenoscope includes a connecting rod 9. A spring 11 is sleeved on the surface of the connecting rod 9. A limit block 12 is installed at one end of the connecting rod 9. A locking block 13 is installed at one end of the limit block 12. One end of the locking block 13 extends through the operating handle 1 into the threaded hole 8. A handle 7 is installed at the top of the operating handle 1, and one end of the handle 7 extends through the operating handle 1 into the interior and connects to the connecting rod 9.

[0026] The threaded surface of the thread 5 is provided with a groove 6, and the locking block 13 is installed inside the groove 6. Through the cooperation between the locking block 13 and the groove 6, when the operator installs the duodenoscope 3, the thread 5 can be screwed into the threaded hole 8. While screwing, the handle 7 can be pulled to move the connecting rod 9, the limiting block 12 and the locking block 13. When the operator tightens the duodenoscope 3, the locking block 13 will automatically lock into the groove 6 under the action of the spring 11, which can further fix the duodenoscope 3. The operation steps are very simple, avoiding the possibility of the duodenoscope 3 falling off after a long period of use. This indirectly improves the connection efficiency between the duodenoscope 3 and the operating handle 1, and the design greatly increases the practicality.

[0027] The duodenoscope 3, the cholangioscope 4, and the operating handle 1 are all fitted with sealing gaskets.

[0028] An adjustment handle 10 is provided on one side of the operating handle 1.

[0029] The specific usage and function of this embodiment are as follows:

[0030] Before installation and use, the operator needs to inspect the internal components or structure of the device. Once the inspection is completed, it can be used normally. First, when installing the duodenoscope 3, the operator can first screw the thread 5 into the threaded hole 8. While screwing, the operator can pull the handle 7 to move the connecting rod 9, the limiting block 12, and the locking block 13. When the operator tightens the duodenoscope 3, the locking block 13 will automatically lock into the slot 6 under the action of the spring 11, which can further fix the duodenoscope 3. The operation steps are very simple, avoiding the possibility of the duodenoscope 3 falling off after a long period of use. This indirectly improves the connection efficiency between the duodenoscope 3 and the operating handle 1, and the design greatly increases the practicality. If it needs to be used again, the above operation can be repeated.
