Problems solved by technology

For another example, when the resected polyps and other diseased tissues are taken out through digestive endoscopy, or when the resected polyps and other diseased tissues are taken out through endoscopes such as enteroscopy, nephroscope or laryngoscope, since it can only be delivered through a small diameter such as 3mm or 1mm diameter , into the human body, there is also the problem of opening the mouth of the retrieval bag, and the endoscopic retrieval bag of the prior art cannot meet these requirements

Embodiment 1

[0121] Embodiment 1: The novel endoscope retrieval bag of the single-hole type slider of the present invention

[0122] refer to figure 1 , figure 2 , Figure 9 to Figure 11 .

[0123] The novel endoscope retrieval bag of the single-hole slider of the present invention comprises a flexible bag 1, an elastic wire 2, a connector 3, and a slider 4; its structure is as follows:

[0124] The flexible bag 1 is a bag-like structure with an open end 11 and a closed end 12 , and a through hole 111 and a joint 112 are provided on the edge of the open end 11 . The junction 112 is usually a heat-sealed edge, and may also be an adhesive edge or a seamed edge. The slider 4 is provided with a through hole 41 , and the elastic wire 2 is movably passed through the through hole 41 of the slider 4 . One end of the elastic wire 2 is fixed to the connector 3 , and the other end is fixed to the slider 4 . The elastic thread 2 is movably passed through the through hole 111 on the open end of ...

Embodiment 2

[0126] Embodiment 2: The novel endoscope retrieval bag of double-hole type slider of the present invention

[0127] refer to Figure 5 to Figure 6 .

[0128] The difference between this embodiment and Embodiment 1 is that the slider 4 adopts a double-hole structure, and both ends of the elastic wire 2 are fixed on the connector 3 . The elastic wire 2 can slide along the two parallel through-holes 41 on the slider 4 to play the role of closing and unfolding the mouth of the flexible bag 1 .

[0129] When the relative distance between the slider 4 and the connecting head 3 increases, the elastic wire 2 is gradually gathered with the slider 4 as the constraint point, thereby closing the opening end 11 of the flexible bag, that is, closing the mouth of the flexible bag 1 .

[0130] When the relative distance between the slider 4 and the connector 3 decreases, the elastic wire 2 is gradually expanded with the slider 4 as the constraint point, and the circular or nearly circular o...

Embodiment 3

[0132] Embodiment 3: The proximal end of the opening end of the flexible bag of the present invention is connected to the slider with a single-hole type slider new endoscope retrieval bag

[0133] refer to Figure 3 to Figure 4 , Figure 16 to Figure 18 .

[0134] The difference between this embodiment and Embodiment 1 lies in that: the proximal end 114 of the opening end of the flexible bag is connected with the slider 4 .

[0135] The near end 114 of the opening end of the flexible bag is connected with the slider 4, the slider 4 can control the movement of the near end 114 of the opening end of the flexible bag, and the relative movement between the slider 4 and the elastic wire 2 can gather or expand the flexible bag The open end 11.

[0136]Lead connecting strip 1140 from the proximal end 114 of the opening end of the flexible bag, and the connecting strip 1140 is a part of the proximal end of the opening end of the flexible bag, that is, a thin strip extended. A thro...

Abstract

The invention discloses a novel endoscope object taking bag and a delivery system. The novel endoscope object taking bag comprises a flexible bag, an elastic silk, a connector and a sliding block. The elastic silk movably penetrates through a through hole at an open end of the flexible bag. The elastic silk can movably penetrate through a through hole of the sliding block, and the sliding block can move along the elastic silk. When a relative distance between the sliding block and the connector is increased, the elastic silk is furled step by step by using the sliding block as an obligatory point, so as to furl a bag mouth of the flexible bag. When the relative distance between the sliding block and the connector is reduced, the elastic silk is unfolded step by step by using the sliding block as the obligatory point, so as to unfold the bag mouth of the flexible bag. The delivery system has a sleeve structure consisting of an outer sheath and an inner sheath. According to the novel endoscope object taking bag and the delivery system, the bag mouth of the novel endoscope object taking bag not only can be opened conveniently in a human body, but also can be closed conveniently, and particularly can be released in the body through a tiny endoscope pipeline, so that an excised sample is taken out, and the defects that the endoscope object taking bag in the prior art cannot be opened after the bag mouth is sealed and is difficult to be delivered through a tiny pipeline are overcome.

Description

technical field [0001] The invention relates to a minimally invasive surgical instrument, in particular to an instrument for excision and tissue removal under laparoscopic surgery, such as an endoscopic object extraction bag. Background technique [0002] Endoscopic surgery is a minimally invasive surgery performed through small incisions. This type of surgery has small incisions, less postoperative pain, and faster recovery, so it has been more and more widely used. However, in the implementation of such operations, how to safely take out the surgically resected large biological tissues through small incisions is a difficult problem encountered in the further development of endoscopic surgery; When liquid tissue or malignant tumor tissue remains in the body, fragmented tissue or overflowing fluid can easily lead to infection, complications, or the spread of cancer cells, endangering other healthy tissues and even the safety of patients. [0003] In order to solve the techn...
