Problems solved by technology

[0004] The purpose of the present invention is to provide a device for biliary tract surgery to solve the problem that the biliary tract stone removal tool in the prior art can only reach the front of the stone and is difficult to reach between the stone and the biliary tract, or to remove the stone behind the stone, so as to closely contact with the biliary tract It is difficult to remove the stones; at the same time, in the narrow position of the biliary tract, it is difficult to deploy the biliary stone removal device to remove the technical problems

Embodiment 1

[0038] see Figure 1 to Figure 3 As shown, this embodiment provides a biliary tract surgery device, including: an outer cannula 1 , a plurality of connecting blocks 6 , a trachea 2 , a balloon 3 and a push rod 5 .

[0039]Wherein, the outer sleeve 1 is tubular and flexible; a plurality of connecting blocks 6 are sleeved in the outer sleeve 1 and arranged in sequence along the length direction of the outer sleeve 1, and a plurality of connecting blocks 6 are A through shaft hole is provided respectively, a protrusion 61 is provided on one side of the connection block 6, and a groove 62 is provided on the other side of the connection block 6, and the protrusion 61 of a connection block 6 is connected to its adjacent The grooves 62 of the block 6 fit and are oppositely arranged. The trachea 2 is flexible, and the trachea 2 is passed through the shaft holes of the multi-block connecting blocks 6 . The balloon 3 is arranged at the distal end of the trachea 2 and is located on the...

Embodiment 2

[0068] The difference between the biliary tract surgery device in this embodiment and the first embodiment is that a plurality of protrusions 61 are arranged at intervals on one side of the connecting block 6 , and adjacent connecting blocks 6 are arranged at intervals on the other side of the connecting block 6 The plurality of protrusions 61 fit into the plurality of grooves 62 respectively. The number of the plurality of protrusions is greater than 2, Figure 4 The sectional view is given in , and only 3 protrusions or grooves are shown on the sectional surface.

[0069]The structures, principles, and operation methods of other components of the biliary tract surgery device in this embodiment are the same as those in the first embodiment, and the cooperation between the groove 62 and the protrusion 61 is also the same as that in the first embodiment.

[0070] The device for biliary tract surgery in this embodiment has the same beneficial effects as those in Embodiment 1, a...

Abstract

The invention relates to the technical field of medical equipment, and discloses a biliary tract operation device. The biliary tract operation device comprises an outer sleeve, a plurality of connecting blocks, an air pipe, a balloon and a push rod. The biliary tract operation device has flexibility when entering the biliary tract, can bend according to the extension direction of the biliary tract, and meets the requirement of smooth entry of the biliary tract operation device into the biliary tract; after entering the biliary tract, a groove and a bulge of the connecting block are matched andconnected, and the biliary tract operation device has relative rigidity, so that the biliary tract operation device can enter into the rear of the stone for stone removal; the biliary tract operationdevice provided by the invention is simple to operate, can be used for removing the stones which are in close contact with the biliary tract, can be used for expanding the biliary tract in the placewhere the biliary tract is narrow, the stone removal is not influenced by the stenosis of the biliary tract, the stone removal rate is high, and the damage is small.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a biliary tract operation device. Background technique [0002] Biliary calculus is a very common surgical disease, with millions of new patients every year in China. There are currently two methods for the treatment of biliary tract stones, one is surgical biliary surgery to remove stones, and the other is endoscopic stone removal. Surgical biliary tract stone removal can be applied to almost all cases of biliary stone removal, and the stone removal is relatively thorough, but at the same time, the operation is relatively traumatic and the recovery is slow. With the advancement of endoscopic surgery and equipment, more and more patients have begun to accept endoscopic minimally invasive stone extraction. This method is characterized by less trauma, quick recovery, and less pain. As few disadvantages as possible. [0003] Endoscopic minimally invasive stone extract...
