Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a novel basket structure. Background Technology

[0002] Bile duct and urinary tract stones have plagued many patients for years, often requiring open surgery in the early stages, and patients needing to spend a considerable amount of time in the hospital to recover. The advent of minimally invasive surgery has greatly reduced patient suffering and shortened hospital stays, and one such instrument is the disposable stone retrieval basket.

[0003] The existing Chinese utility model patent with publication number CN109646075A discloses a stone retrieval basket structure, comprising: a basket body; a basket sheath containing a basket traction wire; a control handle having a front, middle, and rear portion, the front portion having a radially arranged screw receiving hole; a handle sliding block slidably disposed in the middle portion and shifting in the front-rear direction, the handle sliding block having a radially arranged sliding block limiting hole; a handle positioning block fixedly disposed in the rear portion; and a positioning locking mechanism having a ball screw housed in the screw receiving hole, the ball screw having a screw top ball extending out of the screw receiving hole and exposed on the outside of the front portion of the handle. The beneficial effects of this invention are: reducing the operator's labor intensity and avoiding the unsafe factor of stone dislodgement due to unstable grip during stone retrieval.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, the sieve basket commonly used in surgery to remove stones from the bile duct is woven from nickel-titanium alloy wire, which has high tension and toughness. When using the sieve basket, if the stone is large, it is easy for the stone to get stuck in the gaps of the sieve basket, making it impossible to use the sieve basket for subsequent stone retrieval. When grasping the stone, the inside of the sieve basket has a smooth structure, which causes the stone to move. These problems affect the use of the device. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a novel mesh basket structure that effectively prevents large stones from getting stuck in the gaps of the mesh basket during use, thus preventing the subsequent stone retrieval mesh basket from being used. This solves the aforementioned technical problems.

[0007] Technical solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a novel basket structure, comprising a device structure component, wherein the device structure component is internally equipped with a movable structure component that facilitates the basket body 302 to be moved and retrieved, and facilitates subsequent grabbing of stones; the movable structure component is internally equipped with an anti-clogging component that facilitates grabbing of stones and prevents the gap at the upper end of the basket body from getting stuck and affecting subsequent use.

[0009] A movable block is installed at the upper end of the movable structure component, and connecting plates are installed on both sides of the movable block. An air pump is installed on the right side of the connecting plate to facilitate subsequent gas generation.

[0010] The anti-blocking component has a basket body installed at its upper end, a stabilizing block installed on the inner side of the basket body, an airbag installed at the upper end of the basket body, an inflation tube installed on the upper right side of the airbag, and a connecting ring installed on the right side of the inflation tube. The connecting ring connects multiple inflation tubes for easy use later.

[0011] As a preferred embodiment of this utility model, a device shell is installed at the upper end of the device structure component, a sliding groove is installed at the upper end of the device shell, and a connection port is installed on the upper left side of the device shell, which facilitates the subsequent connection of the sheath tube.

[0012] As a preferred embodiment of this utility model, the upper end of the movable structure component is equipped with a sheath tube, and the upper right side of the sheath tube is equipped with a fixing tube. Connecting blocks are installed on the upper and lower sides of the fixing tube, which facilitates the subsequent movement of the fixing tube.

[0013] As a preferred technical solution of this utility model, a pulling steel wire is installed at the upper end of the above-mentioned anti-blocking component, and the pulling steel wire drives the basket body to extend and retract in size.

[0014] As a preferred embodiment of this utility model, the movable structure component is installed inside the device housing in the device structure component, and the anti-blocking component is installed inside the sheath in the movable structure component.

[0015] As a preferred embodiment of this utility model, the upper end of the device housing is made of plastic, and a connecting pipe is installed at the upper end of the connection port.

[0016] As a preferred embodiment of this utility model, the sheath insertion and installation connection port is installed inside the device housing, the fixed tube is installed inside the device housing, the moving block is installed inside the sliding groove, and a baffle plate is installed at the upper end of the moving block.

[0017] As a preferred embodiment of this utility model, the pulling steel wire is installed inside the sheath tube, the upper end of the basket body is cross-shaped, the stabilizing block is a silicone pellet, the connecting ring is connected to the air pump, and the airbag is made of polyurethane material.

[0018] Compared with the prior art, the present invention provides a novel basket structure with the following beneficial effects:

[0019] 1. This utility model, through the design of the overall device, installs an airbag in the gaps of the basket body within the anti-toxic component. An inflation tube is installed at the upper end of the airbag, and a connecting ring is connected to the upper end of the inflation tube. Multiple inflation tubes are connected via the connecting ring for easy connection to an air pump. The air pump inflates the airbag, facilitating the opening of the gaps in the basket body. A stabilizing block, made of silicone granules, is installed inside the basket body to stabilize the grasped stones. The expandable airbag structure opens the gaps in the basket, preventing stones from getting stuck. This effectively prevents stones commonly used in surgery to remove bile duct stones. The basket is woven from nickel-titanium alloy wire, possessing high tension and toughness. When using the basket, large stones can easily get stuck in the gaps, rendering the basket unusable. During stone grasping, the smooth internal structure of the basket allows the stone to move. Attached Figure Description
