Description

Technical Field

[0001] The utility model belongs to the field of retrieval bags, and in particular relates to a retrieval bag for laparoscope. Background Art

[0002] The conventional laparotomy with the existing technology is highly traumatic, and the pain suffered by the surgeon and the patient is relatively large. However, laparoscopic surgery uses several 0.5-1.2 cm incisions in the abdominal wall, and uses channels to perform surgical operations on medical devices and other equipment in the abdominal cavity. It has less trauma and faster recovery. In recent years, surgical operations have mostly adopted minimally invasive operations, that is, colorectal surgery and the like using laparoscopy. However, surgical removal of tumors and other tissues brings many difficulties due to the large size and the inconvenience of the lack of special bags. At present, the removal of tumors and other resected tissues through the natural cavity of the human body, that is, the anorectal passage, avoids the trauma of the abdomen requiring auxiliary incisions.

[0003] Currently, most colorectal surgical specimen collection bags are made of homemade simple sterile plastic bags, which are easy to break, and residual fragments remain in the pelvic surgical area, which is not conducive to subsequent surgical operations; the end of the traditional specimen bag that enters the anus cannot open and close independently, and requires the assistance of others to straighten and open the specimen bag under laparoscopy. The coordinated operation is difficult, takes a long time, and there is a possibility of loosening. In the process of removing the specimen, the specimen will be twisted into a ball and accumulated on the abdominal wall, and the fluid in the intestine will overflow, which can easily cause contamination and tumor metastasis.

[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 laparoscopic retrieval bag.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0007] A laparoscopic retrieval bag comprises a hollow tube, a fixing block is mounted on one end of the hollow tube, a retrieval bag body is mounted on the fixing block, a display screen is mounted on one side of the hollow tube, a handle is mounted on one side of the hollow tube, and an adjustment component is mounted on the fixing block;

[0008] The adjustment component includes a moving block that slides on the hollow tube, a main frame that rotates on the moving block, and a sub-frame that rotates on the main frame. The bag body is arranged on the sub-frame. A connecting block is installed on one side of the moving block. An adjustment block is arranged on the handle, and the connecting block cooperates with the adjustment block.

[0009] Optionally, a first slot is provided on one side of the main frame, a first connecting column is installed on the sub-frame, the first connecting column rotatably fits in the first slot, a second slot is provided on the other side of the main frame, a third slot is provided on one side of the sub-frame, and a plurality of through slots are provided on one side of the fixed block, and both the main frame and the sub-frame are located in the through slots; surgical forceps are inserted through the hollow pipe of the hollow tube to pull the specimen into the specimen bag in the frame, and then the adjustment block is pushed in the opposite direction so that the wedge block is located in another fitting groove, and the first trapezoidal block cooperates with the first trapezoidal groove to pull the connecting block, so that the moving block drives the retrieval bag body on the sub-frame of the adjustment component to shrink, thereby removing the specimen from the shrinking retrieval bag body through the natural cavity.

[0010] Optionally, a plurality of second connecting columns are installed on the movable block, and the second slot holes are rotatably fitted in the second connecting columns. A plurality of third connecting columns are installed at the bottom of the fixed block, and the third slot holes are rotatably fitted in the third connecting columns. A spring is installed between the fixed block and the movable block, and the spring sleeve is arranged on the hollow tube.

[0011] Optionally, a first trapezoidal block and a second trapezoidal block are respectively installed on both sides of the connecting block, a placement groove is provided in the adjusting block, the first trapezoidal block and the second trapezoidal block are located in the placement groove, the first trapezoidal groove and the second trapezoidal groove are provided in the placement groove, the first trapezoidal block and the second trapezoidal block respectively cooperate with the first trapezoidal groove and the second trapezoidal groove, a sliding block is provided on one side of the adjusting block, a sliding groove is provided on one side of the handle, the sliding block slidably cooperates in the sliding groove, a wedge block is provided on one side of the adjusting block, two fitting grooves are provided on one side of the handle, and the wedge block cooperates with the fitting groove; by pushing the adjusting block to slide to one side on the handle, the wedge block is located in one of the fitting grooves, and the second trapezoidal block cooperates with the second trapezoidal groove to push the connecting block, so that the moving block drives the picking bag body on the secondary skeleton of the adjusting component to open, thereby playing the role of propping up the picking bag body.

[0012] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0013] 1. When the laparoscopic retrieval bag is used, the device is taken out from the vacuum sterile bag, and is inserted into the human body through the natural cavity. The device is positioned with the aid of a laparoscope, and the adjusting block is pushed to slide to one side on the handle, so that the engagement block is located in one of the engagement grooves. The second trapezoidal block cooperates with the second trapezoidal groove to push the connecting block, so that the moving block drives the retrieval bag body on the secondary frame of the adjusting component to open, and plays the role of opening the retrieval bag body. The retrieval bag body is fully opened to facilitate tumor removal, and surgical forceps are placed through the hollow channel of the hollow tube to pull the specimen to the bone. The specimen bag in the rack is put into the specimen bag, and then the adjusting block is pushed in the opposite direction so that the wedging block is located in the other fitting groove. The first trapezoidal block cooperates with the first trapezoidal groove to pull the connecting block, so that the moving block drives the taking bag body on the secondary frame of the adjusting component to shrink, so that the shrinking taking bag body can be used to take out the specimen through the natural cavity. The taking device can be opened and closed autonomously, and the specimen bag can be straightened and opened in the abdominal cavity without the assistance of other surgeons. The coordinated operation is simpler to operate than the previous cumbersome and complicated action coordination, takes less time and can reduce the fatigue of the surgeon.

[0014] 2. The laparoscopic retrieval bag can be radially folded to facilitate entry into the natural cavity of the human body. Only the moving rod needs to be pushed and pulled to open the retrieval bag body. No other surgeon assistance is required, which saves manpower and is convenient for surgeons to perform surgical operations. It can prevent the secondary contamination of the abdominal cavity caused by the overflow of contents during the operation.
