Description

Technical Field

[0001] The utility model belongs to the field of specimen sampling, and in particular relates to a laparoscope specimen collecting device. Background Art

[0002] With the widespread development of laparoscopic technology, most gynecological surgeries such as ectopic pregnancy, ovarian tumors and other common and multiple diseases can be performed laparoscopically, and the specimen needs to be removed from a 5-10mm incision.

[0003] A Chinese patent with announcement number CN219763402U discloses a laparoscopic retrieval bag, including a ventilation tube, one end of which is closed and the other end is fixedly connected to a connecting tube; a round frame, at the bottom of which a retrieval bag is installed, and the retrieval bag is a medical rubber bag; a leak-proof component is arranged on the inner side wall of the round frame to prevent the load in the retrieval bag from leaking out. Although the above-mentioned leak-proof component can inflate the four airbag baffles, the four airbag baffles will be inflated and horizontal, thereby covering the round mouth of the round frame to prevent the objects in the sampling bag from falling during the entire sampling and extraction process, but when the above-mentioned sampling bag is used to sample specimens in different positions, the angle of the sampling bag needs to be adjusted, and the angle of the connecting tube needs to be adjusted by hand. Since the incision is small, the connecting tube drives the sampling bag to adjust the angle, which will compress the incision and cause damage to the incision. In addition, the above-mentioned sampling bag needs to insert a cutting tool from the incision to cut the specimen, which increases the difficulty of sampling the specimen.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a laparoscope specimen collection device to solve the problems raised in the above-mentioned background technology.

[0007] A laparoscope specimen collection device comprises: a hand-held rod and a sampling fixing part, a bag frame is installed on one side of the sampling fixing part, a sampling bag is installed on the lower side of the bag frame, and a cutter corresponding to the bag frame is slidably matched on one side of the sampling fixing part;

[0008] An angle adjustment component is arranged between the hand-held rod and the sampling fixed part, a turntable which is rotatably matched with the angle adjustment component is arranged on the hand-held rod, and a pneumatic drive component which is matched with the cutter is arranged between the hand-held rod and the sampling fixed part.

[0009] Optionally, in order to reduce the situation where the hand-held rod swings in the incision and causes damage to the incision, a slot is opened on one side of the hand-held rod, and the angle adjustment assembly includes a first rotating rod rotatably fitted in the slot, a worm gear installed on the periphery of the first rotating rod, and a worm rotatably fitted in the slot and meshing with the worm gear, and connecting plates fixedly connected to one side of the sampling fixing part are installed on both sides of the worm gear, and the worm gear is matched with the turntable transmission; an inner cavity connected to the slot is provided in the hand-held rod, and a second rotating rod rotatably fitted in the inner cavity and matched with the first rotating rod transmission, and the turntable is installed at the end of the second rotating rod that passes through the hand-held rod; a first synchronous wheel is installed on the periphery of the first rotating rod, and a second synchronous wheel is installed on the periphery of the second rotating rod, and a synchronous belt is sleeved between the first synchronous wheel and the second synchronous wheel.

[0010] Optionally, in order to reduce the need for additional cutting tools to cut the specimen and reduce the difficulty of sampling the specimen, a groove is opened on one side of the sampling fixing part, and the pneumatic drive assembly includes a piston slidingly fitted in the groove, a first through groove opened on one side of the sampling fixing part and connected to the groove, a second through groove opened on one side of the hand-held rod, a telescopic bellows connected between the first through groove and the second through groove, and an airbag installed on one side of the hand-held rod and connected to the second through groove.

[0014] By arranging a pneumatic drive assembly between the hand-held rod and the sampling fixing part, when the bag frame is aligned with the specimen, the pneumatic drive assembly drives the cutter to cut the specimen squeezed into the bag frame, and the cut specimen falls into the sampling bag. The cutter seals the bag frame while cutting the specimen. On the one hand, it reduces the possibility of specimens falling during the removal process, and on the other hand, it reduces the need for additional cutting tools to cut the specimen, thereby reducing the difficulty of sampling the specimen.

DETAILED DESCRIPTION

[0025] The utility model will now be further described in detail with reference to the accompanying drawings.

[0026] See also Figure 1-4 As shown, in this embodiment, a laparoscope specimen collection device is provided, comprising: a hand-held rod 1 and a sampling fixing part 2, a bag frame 4 is installed on one side of the sampling fixing part 2, a sampling bag 3 is installed on the lower side of the bag frame 4, and a cutter 5 corresponding to the bag frame 4 is slidably matched on one side of the sampling fixing part 2, wherein the bag frame 4 is an elastic arc plate, and the sampling bag 3 is a medical rubber bag;

[0027] An angle adjustment component 11 is installed between the hand-held rod 1 and the sampling fixed part 2. A turntable 6 that rotates and cooperates with the angle adjustment component 11 is installed on the hand-held rod 1. A pneumatic drive component 7 that cooperates with the cutter 5 is installed between the hand-held rod 1 and the sampling fixed part 2.

[0028] By using the angle adjustment component 11 provided between the hand-held rod 1 and the sampling fixing part 2, the turntable 6 is rotated clockwise or counterclockwise to drive the sampling fixing part 2 to flip upward or downward through the angle adjustment component 11, so that the angle of the sampling bag 3 on the fixing part 2 can be adjusted, thereby reducing the need to hold the hand-held rod 1 by hand to swing in order to adjust the angle of the sampling bag 3, thereby reducing the situation where the hand-held rod 1 swings in the incision and causes damage to the incision; by using the pneumatic drive component 7 provided between the hand-held rod 1 and the sampling fixing part 2, when the bag frame 4 is matched with the specimen, the pneumatic drive component 7 drives the cutter 5 to cut the specimen squeezed into the bag frame 4, and the cut specimen falls into the sampling bag 3. The cutter 5 closes the bag frame 4 while cutting the specimen. On the one hand, it reduces the situation where the specimen falls during the removal process, and on the other hand, it reduces the situation where an additional cutting tool is needed to cut the specimen, thereby reducing the difficulty of sampling the specimen.

[0029] like Figure 3 As shown, a slot 10 is provided on one side of the hand-held rod 1 of the present embodiment, and the angle adjustment assembly 11 comprises a first rotating rod 1101 rotatably fitted in the slot 10, a worm wheel 1102 mounted on the peripheral side of the first rotating rod 1101, and a worm 1103 rotatably fitted in the slot 10 and meshed with the worm wheel 1102, and connecting plates 16 fixedly connected to one side of the sampling fixing part 2 are mounted on both sides of the worm wheel 1102, and the worm 1103 is in transmission cooperation with the turntable 6; an inner cavity connected to the slot 10 is provided in the hand-held rod 1, and a second rotating rod 14 rotatably fitted in the inner cavity and in transmission cooperation with the first rotating rod 1101 is provided, and the turntable 6 is mounted on the end of the second rotating rod 14 that passes through the hand-held rod 1; a first synchronous wheel 12 is mounted on the peripheral side of the first rotating rod 1101, a second synchronous wheel 13 is mounted on the peripheral side of the second rotating rod 14, and a synchronous belt 15 is sleeved between the first synchronous wheel 12 and the second synchronous wheel 13.

[0030] When the angle of the sampling bag 3 needs to be adjusted, the turntable 6 is rotated clockwise or counterclockwise to drive the first rotating rod 1101 to rotate, the first rotating rod 1101 drives the second synchronous wheel 13 to rotate, the second synchronous wheel 13 drives the first synchronous wheel 12 to rotate through the synchronous belt 15, the first synchronous wheel 12 drives the first rotating rod 1101 to rotate, the first rotating rod 1101 drives the worm 1103 to rotate, the worm 1103 drives the worm wheel 1102 to rotate, the worm wheel 1102 drives the sampling fixing part 2 to flip upward or downward through the connecting plate 16, so as to adjust the angle of the sampling bag 3 on the fixing part 2, thereby reducing the need to hold the hand-held rod 1 by hand to swing to adjust the angle of the sampling bag 3, thereby reducing the situation where the hand-held rod 1 swings in the incision and causes damage to the incision.

[0031] like Figure 3-4As shown, a groove 9 is provided on one side of the sampling fixing portion 2 of this embodiment, and the pneumatic drive assembly 7 includes a piston 701 slidingly fitted in the groove 9, a first through groove 702 provided on one side of the sampling fixing portion 2 and connected to the groove 9, a second through groove 703 provided on one side of the hand-held rod portion 1, a telescopic bellows 704 connected between the first through groove 702 and the second through groove 703, and an air bag 705 installed on one side of the hand-held rod portion 1 and connected to the second through groove 703.

[0032] When cutting and collecting specimens, with the cooperation of the laparoscope, the bag frame 4 on the sampling fixing part 2 is brought close to the part where sampling is required, and the airbag 705 is pressed. The gas in the airbag 705 enters the telescopic bellows 704 through the second through groove 703, and the gas in the telescopic bellows 704 enters the second through groove 703. The gas in the second through groove 703 enters the groove 9 to squeeze the piston 701 to move. The movement of the piston 701 drives the cutter 5 to cut the specimen squeezed into the bag frame 4, and the cut specimen falls into the sampling bag 3. The cutter 5 closes the bag frame 4 while cutting the specimen, so that the specimen can be collected, which reduces the need for additional cutting tools to cut the specimen, thereby reducing the difficulty of sampling the specimen.

[0033] like Figure 2 As shown, a limiting groove 8 corresponding to the cutter 5 is provided on the inner side of the bag frame 4 of this embodiment, and a rubber pad is installed in the limiting groove 8;
