Embodiment Construction

[0007] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0008] In the accompanying drawings, the multi-functional stone mesh basket tube sheath 8 is 1.5-2m in total, and the outer diameter is 3-5mm. There are laser-marked scales on the outside for each fixed length, which is convenient for knowing the depth of the sheath into the bile duct. One end (head end) 1 is a telescopic handle controllable by one hand, which is connected with the net basket 5; the other end is the entrance and exit of the net basket and the flushing water outlet. Through the control handle 1, the mesh basket can freely enter and exit the tube sheath to complete the stone removal operation (such as figure 1 ). The inner cavity of the sheath is divided into two chambers, and the inner cavity 7 of the sheath is a stretching and water injection channel for the basket, which can be connected to 6 through a syringe to complete o...

Abstract

The invention relates to a multifunctional biliary tract stone extraction instrument which properly increases the diameter of a tube sheath to 3-5mm on the basis of the traditional biliary tract stone extraction basket. Meanwhile, the past single-cavity tube sheath is changed into a double-cavity tube sheath. An inner cavity can be used for biliary tract rinsing and radiography. An outer cavity is sealed, and the tail end is provided with a saccule-shaped device; the saccule-shaped device is stopped near the outlet of the inner cavity. An amount of water can be injected through an injection port at the position of a handgrip so as to control the size of the saccule. In addition, a scale mark is designed at a distance from the head end to the tail end of the basket tube sheath. The invention can complete the necessary operations of stone extraction, rinsing, radiography, expansion and the like in the biliary tract operation only by one instrument, can be suitable for both coeliotomy and laparoscopic surgery and is easy to master and popularize. The invention changes the current situation that laparoscope biliary tract probe must depend on a laparoscope, thereby being beneficial to the popularization of the biliary tract operations under the laparoscope in the hospitals at all levels.

Description

technical field [0001] The invention relates to a medical treatment device. This kind of multifunctional stone removal mesh basket is suitable for stone removal, contrast imaging, flushing and expansion treatment in patients with extrahepatic and extrahepatic bile duct stones undergoing open or laparoscopic surgery. Background technique [0002] Extrahepatic and extrahepatic bile duct stones are frequently-occurring and common diseases in my country. Stones in the common bile duct can cause biliary obstruction secondary to jaundice, cholangitis, and even life-threatening pancreatitis. Surgery is the only way to treat the disease. Surgery is divided into traditional open surgery and laparoscopic surgery. Due to the special tree-shaped anatomical structure of the bile duct, it is difficult to remove the stones in one go. Usually the method for taking stone has: 1. Probe and take stone along bile duct direction with metal hard stone taking forceps. This method requires ext...
