Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an intestinal isolation and protection device. Background Art

[0002] The small intestine is a major organ in the abdominal cavity, about 4-5 meters long, occupying most of the middle and lower abdomen. The small intestine is free and has a large range of motion due to its long mesentery. When performing abdominal surgery, the mobility and sliding properties of the small intestine often affect the exposure of the surgical site and the operating field. Abdominal surgery generally includes colorectal surgery, gynecological surgery, urological surgery, abdominal aortic lymph node dissection surgery or retroperitoneal surgery and other mid-lower abdomen, pelvic and retroperitoneal surgeries. At present, the main clinical methods to solve this problem are to drastically adjust the patient's body position or cover the small intestine with gauze and have an assistant help pull it, but the effect is not ideal. Using a gauze pad to simply surround the small intestine is enough to achieve fixation. Often due to incomplete protection, the small intestine overflows from the edge of the gauze pad, affecting the surgical operation and causing a series of problems: (1) After entering the abdomen, in order to fully expose the surgical field, the surgeon often has to spend a lot of time and energy to open the small intestine, which invisibly increases the operation time and may increase the risk of secondary damage to the small intestine and its mesentery; (2) During pelvic surgery, in order to make the small intestine slide toward the head, the patient is often placed in a head-down position with the feet down. A high position will compress the patient's lungs, affecting respiratory and circulatory functions, and increasing the difficulty of anesthesia control and ensuring a smooth operation. (3) In laparoscopic surgery, when exposure is difficult, it may be necessary to increase the puncture holes and have the assistant keep the small intestine open, which increases the difficulty of the assistant's cooperation. (4) If the small intestine is not fixed and often slides into the surgical field, there may be a risk of small intestinal injury during thermoelectric surgery such as ultrasonic scalpels and electric scalpels. (5) During surgical operations, especially tumor operations, the small intestine may be contaminated with tumor cells, violating the principle of tumor-free technology. At the same time, during large intestine operations, it is also possible that bacteria in the intestinal cavity may contaminate the small intestine.

[0003] Therefore, when performing mid- and lower abdominal surgery, especially laparoscopic surgery, a device is needed to separate the small intestine from the surgical site to expose the surgical site, so that the doctor can perform the surgery calmly, reduce the operation time and reduce complications. Summary of the invention

[0037] like Figures 1 to 7As shown, the present invention provides an intestinal isolation protection device, which includes an isolation protection bag module 400, a push module 500 and a fixed accessory module 600. The isolation protection bag module 400 includes a support ring 420, an isolation protection bag body 430 and a pulling rod 440. A channel 431 is arranged around the top of the isolation protection bag body 430. The support ring 420 is inserted into the channel 431. A positioning hole 421 is arranged at the end of the support ring 420. A positioning slot 441 is arranged at one end of the pulling rod 440. The positioning hole 421 and the positioning slot 441 are matched by a metal pin. The push module 500 includes a push-pull rod 510 and an outer sleeve 520. The push-pull rod 510 is connected to the pulling rod 440. One end of the outer sleeve 520 is sleeved on the outside of the push-pull rod 510. The isolation protection bag module 400 is compressed and stored in the outer sleeve 520 and can be released to the outside of the outer sleeve 520 by pushing the push-pull rod 510. The fixing accessory module 600 includes a fixing block 610 , and the fixing block 610 is used to fix the pulling rod 440 .

[0038] Before use, the intestinal isolation protection device of the present invention stores and compresses the isolation protection bag module 400 into the outer sleeve 520. When in use, the isolation protection bag module 400 is pushed to the outside of the outer sleeve 520 by the push-pull rod 510 in the push module 500. At this time, the isolation protection bag body 430 is unfolded and restored to its original shape through the support ring 420, and then the pulling rod 440 in the isolation protection bag module 400 is clamped by the fixing block 610 in the fixed accessory module 600. When the isolation protection bag module 400 is released from the outer sleeve 520, the small intestine can be placed in the isolation protection bag body 430, thereby separating the small intestine from the surgical site to expose the surgical site, allowing the doctor to perform the operation calmly, thereby greatly reducing the operation time and reducing complications. At the same time, the device can also reduce the risk of the small intestine being contaminated by tumors and bacteria while protecting the small intestine.

[0039] The isolation protection bag module 400 also includes a puncture head 410, which is in the shape of a bullet head and plays a puncture role when entering the abdominal cavity.

[0040] The pulling rod 440 is a long cylindrical rod, and a corrugated protrusion 443 is designed on the surface of the pulling rod 440 to increase friction in the abdominal wall channel 431 to prevent slipping.

[0041] One end of the push-pull rod 510 is provided with a push-pull handle 511. The other end of the push-pull rod 510 is provided with an external thread column 512, and the end of the pull rod 440 is provided with an internal thread hole 442, which cooperates with the external thread column 512 to achieve assembly and disassembly.

[0042] One end of the outer sleeve 520 is provided with a contoured gripping structure 522 for easy gripping operation, and a sealing ring 523 is provided at the end of the outer sleeve 520, and the sealing ring 523 cooperates with the push-pull rod 510 in the pushing module 500 to achieve sealing of the end of the outer sleeve 520. The outer sleeve 520 is a tubular structure, and the other end of the outer sleeve 520 is provided with a card slot 521, which is assembled with the puncture head 410.

[0043] The fixing block 610 is a spring 613 clamping module, which includes a housing 611, a closing switch 612 and a spring 613. Two closing switches 612 are provided. When the closing switches 612 at both ends are squeezed, the middle channel 614 opens, and when the external force is removed, the middle channel 614 closes. Both closing switches 612 are connected to the housing 611, and the spring 613 is installed between the housing 611 and the closing switch 612. The pulling rod 440 passes through the middle channel 614, and the two closing switches 612 clamp the pulling rod 440.

[0044] The support ring 420 is made of a compressible elastic memory alloy, inserted in the channel 431 around the opening of the isolation protection bag, and is elliptical in its natural state. It is compressed and stored in the outer sleeve 520. During surgery, it can be expanded and restored to its original shape after being pushed into the abdominal cavity by the pushing module 500, and is used to prop open the opening of the isolation protection bag body 430.

[0045] When performing colorectal cancer surgery, uterine and adnex surgery, bladder and ureter surgery, abdominal aortic lymph node dissection surgery or retroperitoneal large blood vessel surgery, etc., the push module 500 of the intestinal isolation protection device is passed through the laparoscopic puncture device or the abdominal wall opening to reach the abdominal cavity, and the isolation protection bag module 400 is pushed out of the outer sleeve 520 by pushing the push-pull rod 510, and is separated from the contraction device and opened into a bag shape with the assistance of the surgical grasping forceps. Then, the small intestine free in the middle and lower abdomen is gently placed into the isolation protection bag body 430 using the grasping forceps, and the edge of the isolation protection bag module 400 is pulled to push the isolation protection bag module 400 wrapped in the small intestine to a position far away from the surgical operation. The fixed accessory module 600 is used to fix it to quickly expose the surgical field of view, reduce the influence of the small intestine on the surgery, speed up the surgical process, and reduce the risk of the small intestine being contaminated by tumors and bacteria, thereby playing an isolation and protection role for the small intestine.
