Embodiment 1

[0031] Such as Figure 1-2 As shown, the clinical lithotriptor for hepatobiliary surgery proposed in this embodiment includes a support shaft 28. Two ends of the support shaft 28 are fixedly connected with two symmetrical second fixing blocks 17, and the second fixing blocks 17 are hinged with three-jaw forceps. 11. The three-jaw pliers can be relatively rotated; the support shaft 28 is provided with a cavity 21 along the length direction, and a push rod 30 is slidably provided in the cavity 21. One end of the push rod 30 penetrates the cavity 21 and extends to the outside, and the cavity 21 and The push rod 30 is matched, and the push rod 30 can slide relatively in the cavity 21; the cavity 21 is also provided with a first spring 22, the left end of the first spring 22 is fixedly connected with the push rod 30, the first spring 22 The right end is fixedly connected with the support shaft 30. When the push rod 30 moves, the first spring 22 also displaces at the same time, which...

Embodiment 2

[0036] Reference attachment image 3 , The other structure is the same as the first embodiment, the difference is that in this embodiment, the entire device is also provided with a funnel-shaped collector 10, the funnel-shaped collector 10 is a semicircular funnel, and distributed throughout the crush The lower part of the stone clamping device to prevent insufficient collection of crushed stones; the bottom end of the funnel-shaped collector 10 is fixedly connected to the cylindrical container 8, and the bottom end of the cylindrical container 8 is screwed with a screw cap 7, which can be used Rotate to open. When the cylindrical container 8 is filled with crushed stones, unscrew the screw cap 7 to facilitate the removal of the crushed stones; the connection between the funnel-shaped collector 10 and the cylindrical container 8 is provided with a brush 9 that can function as a one-way valve. .

[0037] The bottom end of the push rod 30 is also provided with a second upper rack 2...

Abstract

The invention discloses a clinical calculus removing device and method for a hepatological surgery department. The device comprises a supporting shaft and a calculus breaking electrode, wherein a handle is fixedly connected to the bottom end of the supporting shaft; a three-jaw clamp is hinged to the left end of the supporting shaft; a cavity is formed in the supporting shaft in the length direction; a push rod is arranged in the cavity in a sliding mode; one end of the push rod penetrates out of the cavity and extends to the outside; a connecting rod is hinged to the penetrating part of the push rod and hinged to the three-jaw clamp; the calculus breaking electrode is fixedly connected to the left end of the push rod; a hook handle is slidably connected to the upper end of the handle anddrives the push rod to move leftwards and rightwards through a transmission mechanism; the right end of the hook handle is connected with the handle through a second spring; a second upper rack is arranged at the bottom end of the push rod; the right end of a funnel-shaped collector is in sliding connection with the supporting shaft; a second lower rack is arranged at the upper end of the funnel-shaped collector; and a second gear is connected between the second upper rack and the second lower rack in a meshed mode. The operation is simple, and the operation difficulty is reduced through a gear mechanism; and the arranged movable funnel-shaped collector is used for recycling, so that the operation time is effectively saved.

Description

Technical field [0001] The invention relates to the technical field of medical equipment, in particular to a clinical stone removal device and method for hepatobiliary surgery. Background technique [0002] Hepatobiliary stones are a common and frequently-occurring disease, which refers to stones that occur in any part of the hepatobiliary system. According to the chemical composition of the stones, hepatobiliary stones are divided into cholesterol stones, gallstones and mixed stones. Treatment methods include surgical lithotripsy, western medicine treatment, and traditional Chinese medicine treatment. [0003] At present, surgical treatment is the main treatment method for intrahepatic bile duct stones. The surgical method can be selected according to the current situation and the location of the stones. It can be cut and removed by bile duct, bile duct and intestinal anastomosis and drainage, and partial hepatectomy. At present, the commonly used clinical stone removal devices m...
