Embodiment 1

[0043] Such as Picture 1-1 and Figure 1-2As shown, a minimally invasive surgery retrieval bag device created by the present invention includes a recovery bag 10, a support rod 20 and a pulling assembly. It includes a closing drawstring 31 and an anti-falling drawstring 32. The closing drawstring 31 penetrates into the closing circle 111 and extends outside the closing circle 111. A part of the anti-falling drawing rope 32 is connected to the support rod 20, and the other part is connected to the recycling bag 10. Connection; a part of the closing ring is set on one end of the support rod, and the recovery bag is wound and fixed on the support rod as a whole.

[0044] The connection between the anti-falling stay cord 32 and the support bar 20 is a variety of forms such as engagement, tethering, hooking, ferrule, bonding or snapping, etc. The purpose is to allow the anti-falling stay cord 32 to be attached to the support bar 20 so as to Prevent the recovery bag 10 connected w...

Embodiment 2

[0048] Such as figure 2 As shown, it is a structural schematic diagram of another embodiment of the retrieval bag device for minimally invasive surgery created by the present invention, which has the structure in Embodiment 1, and the support rod 20 penetrates the closing ring 111 of the pocket 11 of the recycling bag 10 Inside, the length L of its penetration is not more than half of the circumference of the closing ring 111. Since the circumference of the cuff ring 111 is much longer than the length L of the part penetrated by the support rod 20, there are not many parts of the cuff ring 111 that can be supported by the support rod 20, and the remaining unsupported cuff ring 111 is In the free state, it will hang down from the side of the support rod 20 , so that the mouth 11 of the recovery bag 10 can be opened naturally, so that the operator can put the resected tissue into the recovery bag 10 conveniently.

Embodiment 3

[0050] Such as Figure 3-1 As shown, a minimally invasive surgery retrieval bag device created by the present invention has the structure in Embodiment 1, and the support rod 20 includes an elastic part 21 and a rigid part 22, and the closing ring 11 is sleeved on the support rod On the elastic part 21 of 20, a part of anti-falling pull cord 32 is connected on the rigid part 22, and the recycling bag 10 is wound and fixed on the elastic part 21 of the support rod 20 as a whole.

[0051] Such as Figure 3-2 As shown, a support rod 20 with an arcuate elastic portion 21 having an elastic portion 21 and a rigid portion 22 is shown. The elastic part 21 is prefabricated into an arc, so that after the closing ring 111 on it is naturally unfolded in the patient's body, the mouth 11 of the recovery bag 10 will naturally open for a certain distance, which is helpful for the operator to use the clamp 60 Quickly clamp a part of the pocket 11, thereby quickly opening the pocket 11 of the...

Abstract

The invention relates to a bag device for minimally invasive surgery, which comprises a recycling bag (10), a support rod (20) and a pulling assembly, the bag opening (11) of the recycling bag (10) isprovided with a retracting ring (111), the pulling assembly comprises a retraction rope (31) and an anti-falling pulling rope (32), wherein the retraction rope (31) penetrates into the retraction ring (111) and extends outside the retraction ring (111), one part of the anti-falling pulling rope (32) is connected to a support rod (20) and the other part is connected to a recovery bag (10); a partof the retraction ring (111) is sleeved on one end of the support rod (20), and the recovery bag (10) is integrally wound and fixed on the support rod (20). As that invention does not require an external sleeve to bind the recovery bag, the recovery bag can be smoothly opened in the patient body, and the invention has the advantage of simple structure and low cost.

Description

[0001] The patent application of the present invention is a divisional application filed on October 31, 2017 with the application number CN201711049270.1 and the title of the invention "A Retrieval Bag Device for Minimally Invasive Surgery". technical field [0002] The present invention relates to a surgical instrument for recovering tissue, especially a surgical instrument in minimally invasive surgery for resecting tissue through a small incision, such as a sample recovery bag device or an extraction bag device. Background technique [0003] Minimally invasive surgery is a kind of surgical operation, which is usually completed by making a series of small incisions on the patient's body. This surgical operation does not require large incisions, which is beneficial to shorten the recovery time of the patient and at the same time benefit Patients reduce unnecessary bodily harm. [0004] When it is necessary to transfer the excised tissue from the body to the outside of the b...
