Embodiment Construction

[0013] Attached below Figure 1~5 The present invention is described in detail below.

[0014] like Figure 1~5 As shown, the present invention includes an outer cylinder 1, a partition 2, a calculus removal device, and an infusion device. The outer cylinder 1 is provided with a first through hole 1-1 in the middle of the left and right ends and the front end of the first through hole 1-1 is arranged There is a cylindrical structure with a second through hole 1-3. The rear end of the first through hole 1-1 is provided with a first through groove 1-2 and a partition 2 is fixed in the middle of the outer cylinder 1. The partition The plate 2 is correspondingly provided with a first through hole 1-1 and a second through hole 1-3, and the upper end of the first through hole 1-1 is provided with a card slot 2-1, which limits the position of the inner cylinder 3 so that the inner cylinder 3 It can only move left and right and cannot rotate, so as to avoid movement interference bet...

Abstract

The invention relates to the technical field of medical instruments, and particularly relates to a stone removing device for hepatobiliary surgical operation. The device comprises an outer tube, a baffle, a stone removing device body and an infusion device, a first through hole is formed between the left and right ends of the outer tube, a cylindrical structure of a second through hole is formed in the front of the first through hole, the rear ends of the first through hole is provided with a first through groove, the baffle is fixedly connected with the middle of the interior of outer tube, afirst through hole and a second through hole are correspondingly formed in the baffle, and a clamping groove is formed in the upper end of the first through hole. The stone removing device has the advantages that the structural design is reasonable, a T-shaped rod is pushed leftwards and rotated to achieve the wrapping of a large stone and the cutting and clamping of remaining small connective tissues, the T-shaped rod is rotated rightwards and pulled to retract the stone removing device back to the interior of the outer tube, a syringe extends out from the second through hole to convenientlyinject medicines, the function is comprehensive, the vision is broad, and the stone removing device is provided with better popularization prospects.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a calculus removal device for hepatobiliary surgery. Background technique [0002] A solid mass formed in the lumen of a duct or in a lumen of a luminal organ (such as the kidney, ureter, gallbladder, or bladder, etc.) in a human or animal body, mainly found in the gallbladder, bladder, and renal pelvis, but also in the pancreatic duct and salivary gland In the cavity of the catheter, etc., the stones are composed of inorganic salts or organic matter. There is usually a core in the stones, which is composed of exfoliated epithelial cells, bacterial masses, parasite eggs or worms, feces or foreign objects. Stones can cause lumen obstruction. Affect the fluid discharge of the affected organs, resulting in symptoms such as pain, bleeding, or secondary infection; most gallstones have no clinical symptoms, the typical symptom of gallstones is biliary colic, and some patients c...
