Description

Technical Field

[0001] The utility model relates to the technical field of medical device cleaning equipment, in particular to a laparoscope inner wall cleaning brush straightening device. Background Art

[0002] The laparoscope inner wall cleaning brush is used to clean surgical residues in the instrument channel of endoscopes (gastroscopes, colonoscopes, bronchoscopes, etc.), such as blood stains, tissue debris and other residues. The cleaning brush consists of a blunt head, a brush part, a slender steel wire part and a handle. The blunt head is generally made of metal or hard rubber and is round, ensuring that the cleaning brush can pass smoothly along the instrument channel without damaging its inner wall during the forward movement; the brush part is composed of nylon bristles, and the diameter and wire diameter of the bristles vary according to the model of the cleaning brush; the wire diameter of the slender steel wire part is about 1.5mm, and the length is 800mm~2000, which allows the brush head to enter the entire instrument channel.

[0003] Many brushes bend during use. Regardless of whether the cleaning brush is cheap or not, it is possible for the brush to bend during the first use. Moreover, when the bent brush is used to clean the laparoscope, the bent part will rub against the inner wall of the laparoscope. In actual use, the brush is usually straightened by hand. Due to the manufacturing material of the brush, it is difficult to straighten it by hand, and the straightening effect and efficiency are very poor. Utility Model Content

The gap between the first roller 20 and the second roller 21 can be adjusted according to the specifications of the laparoscope inner wall cleaning brush to ensure that the two can effectively straighten the laparoscope inner wall cleaning brush.

[0032] In one embodiment of the utility model, the moving structure 30 includes a rotating member 31, a moving member 32 and a first elastic member 33. The mounting plate 11 is provided with a channel 12. The moving member 32 and the rotating member 31 are both mounted in the channel 12 and meshed with each other. The clamping structure 40 is mounted on the moving member 32 for clamping the cleaning brush. The first elastic member 33 is mounted on the mounting plate 11 and abuts against the moving member 32. The moving member 32 is provided with a plurality of card slots 321, and the rotating member 31 is provided with a plurality of card platforms 311.

The first elastic member 33 can be a spring. When the rotating member 31 rotates to a preset angle, that is, all the card tables 311 are disengaged from the card slot 321, the rotating member 31 is disengaged from the movable member 32. At this time, the elastic force of the first elastic member 33 is restored, pushing the movable member 32 back, so that the clamping structure 40 returns to its original position, and re-clamps and pulls the next section of the laparoscope inner wall cleaning brush.

[0035] In one embodiment of the utility model, the clamping structure 40 includes a shell 41, two clamping members 42 and a pushing member 43. The shell 41 is connected to the moving member 32 and suspended in the channel 12. The two clamping members 42 are installed in the shell 41, and the parts exposed in the shell 41 clamp the cleaning brush toward each other.

Inclined surfaces 421 are respectively provided on the two clamping members 42, and the inclined surfaces 421 on both sides face each other. The extrusion platform 431 can squeeze the two clamping members 42 apart through the angle formed by the inclined surfaces 421.

[0037] The two clamping members 42 are respectively provided with a second elastic member 44, and the second elastic member 44 can be a spring. The second elastic member 44 presses against the side wall of the accommodating groove 41a, wherein the side wall of the movable groove 41b begins to have a first positioning groove 45 and a second positioning groove 46, and the pushing member 43 is provided with a convex strip 432; the first positioning groove 45 is relatively far away from the first roller 20, and the second positioning groove 46 is relatively close to the first roller 20.

[0038] The mounting plate 11 is provided with a first touch platform 18 and a second touch platform 19, wherein the first touch platform 18 is relatively close to the first roller 20, and the second touch platform 19 is relatively far away from the first roller 20.

On one side of the first roller 20, during the displacement process, the squeezing platform 431 squeezes the two clamping members 42 apart, and at this time, the parts of the two clamping members 42 exposed outside the shell 41 are separated, releasing the laparoscope inner wall cleaning brush, and at the same time following the movable member 32 to rebound to the initial position, when returning to the initial position, the exposed end of the pushing member 43 abuts against the first touch platform 18, and the pushing member 43 is displaced again, and the convex strip 432 disengages from the second card slot 46 and is inserted into the first card slot 45, and at the same time, the elastic force of the second elastic member 44 restores and pushes the two clamping members 42 to move toward each other, re-clamping the laparoscope inner wall cleaning brush, and clamping and pulling the next section of the laparoscope inner wall cleaning brush.

[0039] Working principle: the laparoscope inner wall cleaning brush is passed through the gap between the first roller 20 and the second roller 21, and the end is clamped by the two clamping members 42, and then the driving member 50 is started to rotate the rotating member 31 to drive the movable member 32 to move away from the first roller 20, and the clamping structure 40 moves along with the movable member 32 to clamp and pull the laparoscope inner wall cleaning brush until the rotating member 31 is completely separated from the movable member 32, and the exposed end of the pushing member 43 abuts against the second touch platform 19, and the laparoscope inner wall cleaning brush is released while the movable member 32 rebounds. When it returns to the initial position, the exposed end of the pushing member 43 abuts against the first touch platform 18, so that the two clamping members 42 move toward each other, re-clamp the laparoscope inner wall cleaning brush, and clamp and pull the next section of the laparoscope inner wall cleaning brush.
