An endoscope stone retrieval basket

Abstract

The invention relates to the field of medical equipment, in particular to an endoscope stone retrieval basket. The technical problem to be solved is: providing an endoscope stone retrieval basket. The technical solution of the present invention is: an endoscope stone retrieval basket, including a clamping sleeve, a wedge-shaped silica gel block, a first rotating rod, a first hand wheel, an extraction adjustment mechanism, a stone transfer mechanism and a stone retrieval basket; the inner wall of the clamping sleeve A wedge-shaped silica gel block is arranged symmetrically; the upper part of the clamping sleeve is screwed with the first rotating rod. The invention realizes the synchronous adjustment of the left and right hands, and cooperates with the stable control of the stone retrieval basket, which can ensure the stability of the rhythm during use, and will not cause excessive shaking problems; nor will it cause slippage, and can ensure accurate control. ; It also prevents damage to the ureter caused by twitching when the hand is kept in the air for a long time; at the same time, it is more in line with ergonomics, and the structure is flexible and easy to operate.

Description

Technical field [0001] The present invention relates to a field of medical devices, in particular to an endoscopic stone basket. Background [0002] The stone basket consists of a mesh basket (nitinol wire), a sheath tube (304 stainless steel wire mesh, polyimide) and a control handle (plastic). Product ethylene oxide sterilized, single use. It is mainly used to capture and remove ureteral stones under endoscopy. [0003] Ureteral stones are generally caused by kidney stones being temporarily obstructed in the narrowing of the ureter during the discharge process. Primary ureteral stones are rare. If the ureteral stones are not excreted, they may grow gradually at the site of stay. Ureteral stones are often accompanied by obvious symptoms such as renal colic, hematuria, and ureteral stones often cause obstruction and hydronephrosis, which require emergency treatment; too many people's uncoordinated lifestyles lead to a high incidence of stones. [0004] The existing stone basket ...

Problems solved by technology

[0006] In order to overcome the small size of the control handle of the existing stone fetching basket, its size is relatively thick and thin compared to the index finger of an adult, and doctors need to wear medical gloves during the operation, especially for some doctors with large fingers, it is impossible to operate the control handle. Stable control; because it is necessary to obtain the image of the stone through the cooperation of the endoscope when removing the stone, and at the same time cooperate with the image information to control the movement of the stone retrieval basket to remove the stone. During this process, the position of the stone needs to be adjusted appropriately according to the shape of the stone. There will be pulling wires and constantly loosening and releasing the stone retrieval basket to adjust the position of the stone, but the design of the push-pull rod and positioning pin of the existing control handle is unreasonable, and the control parts are too small. Doctors often need to cooperate with both hands to buckle the push-pull rod and positioning pin , which leads to the doctor's hand needing to be kept stable for a long time, which greatly increases the doctor's workload, and has the disadvantage of being unable to maintain a long-term stable adjustment. The technical problem to be solved is: to provide an endoscopic stone retrieval basket
