Abstract
Description
Technical Field
[0001] This utility model relates to the field of endoscopic stone retrieval basket technology, and in particular to a uroscope-compatible stone retrieval basket. Background Technology
[0002] There are various molding methods for stone retrieval baskets on the market. To ensure that the stone retrieval basket does not scratch the human body when working in the urethra or bile duct and can be fully opened, stone retrieval baskets on the market are generally divided into headless baskets and headed baskets. Headed baskets generally have an end cap device at the front end, which makes the overall opening size of the basket smaller than that of headless baskets. Therefore, hospitals generally use headless baskets more often for urethral and bile duct stone removal.
[0003] Headless stone retrieval baskets on the market are available in two forms: those formed by winding nickel-titanium wire or those formed by cutting nickel-titanium tubes. Wire-wound baskets offer better results, eliminating sharp edges that could cause cuts, but their complex structure, cumbersome manufacturing process, and low production efficiency lead to this problem. Nickel-titanium tube baskets offer high production efficiency, but are prone to sharp edges that could cause cuts. Therefore, we propose a stone retrieval basket for uroscopes that is both safe and quick to form, preventing cuts. Utility Model Content
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0005] A uroscope-compatible stone retrieval basket includes a nickel-titanium wire, an annular hole, and an outer sleeve. Two nickel-titanium wires are provided, which pass through the annular hole and are arranged in a cross shape. The annular hole is fixedly connected to the nickel-titanium wire, and the outer sleeve is fitted over the outside of the tail end of the nickel-titanium wire.
[0006] Preferably, the annular hole and the nickel-titanium wire are connected by adhesive dispensing and curing.
[0007] Preferably, the adhesive coating on the front end of the nickel-titanium wire is in the shape of a bead to avoid scratching the human body.
[0008] Preferably, the maximum diameter of the dispensing boundary does not exceed the maximum diameter of the annular hole.
[0009] Compared with the prior art, the present invention has the following advantages:
[0010] (1) This utility model adopts a nickel-titanium wire interpenetrating ring hole structure, which makes the basket form quickly and the production speed is much higher than that of the wire winding method.
[0011] (2) In this utility model, nickel-titanium wires pass through to form a basket, and the front end of the basket is cured with glue and ring holes to prevent the wires from moving during operation. At the same time, since the glue is in the shape of beads, it can play a protective role at the front end and will not scratch the human body. The manufacturing process is simple and fast, which greatly improves production efficiency. Attached Figure Description

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0017] like Figure 1-3 As shown, this utility model discloses a urinary endoscope-compatible stone retrieval basket, comprising a nickel-titanium wire 1, annular holes 2, and an outer sleeve 4. Two nickel-titanium wires 1 are provided, which are inserted through the annular holes 2 in a cross-shaped arrangement. The annular holes 2 are fixedly connected to the nickel-titanium wires 1. The outer sleeve 4 is fitted onto the outer end of the nickel-titanium wire 1. This utility model uses a structure where the nickel-titanium wires 1 are inserted through the annular holes 2 to form the basket, resulting in rapid basket formation.
[0018] After the basket is shaped, the front end, i.e. the connection between the annular hole 2 and the nickel-titanium wire 1, is cured and connected with a biocompatible UV-curable adhesive to prevent the basket wire from shifting during operation. The adhesive 3 is applied to the front end of the nickel-titanium wire 1 in a bead shape. The maximum diameter of the adhesive 3 boundary does not exceed the maximum diameter of the annular hole 2, which can effectively prevent scratching the human body.
[0019] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
