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.

[0041] like Figures 1 to 9 As shown, the present invention provides an intestinal isolation protection device, which includes an isolation protection bag module 100, a push module 200 and a fixed accessory module 300. The push module 200 includes a push-pull rod 210 and an outer sleeve 220. The isolation protection bag module 100 is in a curled storage state in the outer sleeve 220. The push module 200 releases the isolation protection bag module 100 from the outer sleeve 220 by pushing the push-pull rod 210. The fixed accessory module 300 includes a pull line 320 and a fixing clip 330. The pull line 320 is used to hook the isolation protection bag module 100. After the pull line 320 pulls the isolation protection bag module 100 to the target area, the fixing clip 330 can be used to clamp the pull line 320.

[0042] Before use, the intestinal isolation protection device of the present invention rolls up the isolation protection bag module 100 and stores it in the outer sleeve 220. When in use, the isolation protection bag module 100 is pushed to the outside of the outer sleeve 220 by the push-pull rod 210 in the push module 200, and then the isolation protection bag module 100 is hooked by the pull line 320 in the fixed accessory module 300. After the pull line 320 pulls the isolation protection bag module 100 to the target area, the pull line 320 can be clamped with the fixing clamp 330. When the isolation protection bag module 100 is released from the outer sleeve 220, the small intestine can be placed in the isolation protection bag module 100, 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.

[0043] The isolation protection bag module 100 includes an isolation protection bag body, which is a bag-like net bag structure. An opening is provided on the top of the isolation protection bag. The isolation protection bag can be fully unfolded after entering the abdominal cavity to accommodate free small intestine or other organs that obstruct the surgical field of view.

[0044] The pushing module 200 further includes a heat shrink ring fastener 230 . A push-pull handle 211 is disposed at one end of the push-pull rod 210 . A first annular groove 212 is disposed at the other end of the push-pull rod 210 . The first annular groove 212 is used to fix the shrink film 240 .

[0045] The push module 200 also includes a contraction film 240, which is located between the isolation protection bag module 100 and the outer sleeve 220. The contraction film 240 is used to contract and fix the curled and stored isolation protection bag module 100 when the isolation protection bag module 100 is loaded into the outer sleeve 220, so as to reduce the friction between the isolation protection bag module 100 and the wall of the outer sleeve 220. A second annular groove 221 is provided at one end of the outer sleeve 220, and the second annular groove 221 is used to fix the contraction film 240. The second annular groove 221 and the first annular groove 212 are respectively matched with the second opening and the first opening of the contraction film 240 through the heat shrink ring fastener 230, which is used to seal the inner space of the outer sleeve 220 to prevent air leakage after the push module 200 enters the abdominal cavity. Specifically, the heat shrink ring fastener 230 can shrink and tighten by heating, thereby achieving fixation.

[0046] The other end of the outer sleeve 220 is provided with a contoured grip structure 222 for easy gripping operation.

[0047] The pushing module 200 also includes a sealing cover 223 and a sealing sleeve 224. The sealing cover 223 is arranged at one end of the outer sleeve 220. When the isolation protection bag module 100 is received into the outer sleeve 220, the outer sleeve 220 is sealed. The sealing sleeve 224 is arranged at the other end of the outer sleeve 220. The sealing sleeve 224 is a silicone member with a hole in the middle. The diameter of the hole is smaller than the diameter of the push-pull rod 210. When the push-pull rod 210 is inserted, it can play a role in positioning and increasing the damping feel.

[0048] The fixed accessory module 300 also includes a puncture needle 310. The puncture needle 310 is a hollow needle tube structure as a whole. One end of the puncture needle 310 is provided with a sharp needle tip 311 for puncturing the abdominal wall. The other end of the puncture needle 310 is provided with an operating handle 312 for the operator to hold conveniently.

[0049] One end of the pulling wire 320 has a hook structure 321, which is convenient for hooking the isolation protection bag module 100 in the abdominal cavity. The other end of the pulling wire 320 is curved to prevent the pulling wire 320 from completely sliding into the abdominal cavity.

[0050] The fixing clip 330 is a Robert's clip, and the opening edge of the fixing clip 330 is provided with a detachable boss 331. The Robert's clip can be detached with one hand, and is convenient to use. After the traction line 320 pulls the isolation protection bag module 100 to the target area, the fixing clip 330 can be used to clamp the traction line 320 to prevent it from slipping, thereby positioning the isolation protection bag module 100.

[0051] The device of the present invention is an intestinal isolation and protection device that can separate the small intestine from the surgical site during mid- and lower abdominal, pelvic and retroperitoneal surgeries such as colorectal cancer surgery, uterine and adnex surgery, bladder and ureter surgery, peri-aortic lymph node dissection surgery or retroperitoneal great vessel surgery, thereby reducing the impact of the small intestine on the surgery and reducing the risk of the small intestine being contaminated by tumors and bacteria.

[0052] like Fig. 9 As shown, during colorectal cancer surgery, uterine and adnexal surgery, bladder and ureteral surgery, abdominal aortic lymph node dissection surgery or retroperitoneal great vessel surgery, the push module 200 of the intestinal isolation and protection device is passed through the laparoscopic puncture device 5 or the abdominal wall opening to reach the abdominal cavity, and the isolation and protection bag module 100 is pushed out of the outer sleeve 220 by pushing the push-pull rod 210. Then, the small intestine free in the middle and lower abdomen is gently put into the mesh bag using surgical forceps 4, and the mesh bag wrapped in the small intestine is pushed to a position away from the surgical operation by pulling the edge of the mesh bag. The fixed accessory module 300 is used to fix it, so that the surgical field of view can be quickly exposed, the influence of the small intestine on the surgery can be reduced, the surgical process can be accelerated, and the risk of the small intestine being contaminated by tumors and bacteria can be reduced, thereby playing an isolation and protection role for the small intestine.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
