Embodiment 1

[0030] Such as figure 1 , 2 As shown, the laparoscopic retrieval bag adopting the pocket structure of the present invention includes a pocket body 1 and a pocket ring 2; the pocket body 1 is provided with an annular ring 3 along the circumference, and the pocket ring 2 is sleeved in the annular ring 3 The pocket ring 2 comprises a section of arc-shaped elastic wire 21 and a section of string 22, and the two ends of the elastic wire 21 are connected to the two ends of the string 22 respectively; There is an opening 31 . The arc length of the elastic metal wire 21 is longer than the length of the string 22 . The string 22 is a string with stretching elasticity. The annular ring 3 is formed by curling the pocket body 1 outward along the circumferential direction.

[0031] When using the above-mentioned laparoscopic retrieval bag, first stretch the elastic metal wire 21 and the string 22 into a "one" shape, and then insert it into the abdominal cavity from the operation port; ...

Embodiment 2

[0033] a method such as image 3 The laparoscopic retrieval bag with the pocket structure shown in the example, the laparoscopic retrieval bag of this embodiment is basically the same as that of Embodiment 1, the difference is that the elastic metal wire 21 located at the opening 31 protrudes outward to form a detour as a handle Part 211 (other forms of handles can also be used).

[0034] It is easier to pull the elastic metal wire 21 through the detour part 211 , which facilitates the folding of the elastic metal wire 21 , so that it is convenient to curl the mouth of the bag into a shorter strip.

Embodiment 3

[0036] a method such as Figure 4 The laparoscopic retrieval bag with the opening structure shown in the example is basically the same as the laparoscopic retrieval bag in Embodiment 1, except that the elastic wire 21 at the opening 31 is provided with a drawstring 4 . The drawstring 4 is a drawstring with a color different from that of the pocket body 1 .

Abstract

The invention discloses a bag opening structure and a laparoscopic object taking bag adopting the same. The bag opening structure comprises a bag opening body and a bag opening ring; an annular ring is arranged on the bag opening body in the circumferential direction, and the bag opening ring is arranged in the annular ring in a sleeved mode; the bag opening ring comprises an arc-shaped elastic metal wire and a string, and the two ends of the elastic metal wire are connected with the two ends of the string respectively; the position, provided with the elastic metal wire, of the annular ring is at least provided with one opening. According to the bag opening structure and the laparoscopic object taking bag adopting the same, due to the fact that the arc-shaped elastic metal wire is arranged, the bag opening can be conveniently folded into a strip to be put into the abdominal cavity, the laparoscopic object taking bag adopting the bag opening structure is unfolded after entering the abdominal cavity, the elastic metal wire restores to a natural arc-shaped state, the two sides of the bag opening are naturally separated, and operation is convenient; when the laparoscopic object taking bag is taken out of the abdominal cavity, the elastic metal wire is pulled and drawn out of the annular ring on the bag opening body, the string connected with the elastic metal wire can tighten the annular ring, the bag opening is closed, and liquid in the laparoscopic object taking bag cannot spill.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a pocket structure and a laparoscopic retrieval bag using the pocket structure. Background technique [0002] Laparoscopic surgery (laparoscopic surgery) is a very popular surgical method in recent years. Unlike traditional surgical procedures that require the patient to be opened and laparotomy, laparoscopic surgery only needs to open 3 to 4 (or less) surgical openings for surgery. Laparoscopic surgery is to send tools and image detection instruments (such as endoscopes) required for surgery into the abdominal cavity through a puncture cannula (trocar), and then inflate them into the abdominal cavity of the human body, and perform surgery by observing through the imaging system. Due to the small wound of laparoscopic surgery, it can not only reduce the postoperative pain, but also shorten the hospital stay, and return to normal life earlier. These are the advantages of laparoscop...
