Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly 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 mid - lower abdominal area. Also, due to its long mesentery, it is in a free state and has a large degree of mobility. When performing abdominal surgery, the free - moving and sliding nature of the small intestine always affects the exposure of the surgical site and the operative field. Abdominal surgery generally includes surgeries in the mid - lower abdomen, pelvic cavity, and retroperitoneum such as colorectal surgery, gynecological surgery, urological surgery, lymph node dissection around the abdominal aorta, and retroperitoneal surgery. Currently, clinically, mainly methods such as significantly adjusting the patient's position, covering the small intestine with gauze, and having an assistant support the traction are used for treatment, but the effect is not satisfactory. Since it only simply surrounds and fixes the small intestine with a gauze pad, the protection is always incomplete, and the small intestine may protrude from the edge of the gauze pad, not only affecting the surgical operation but also causing the following problems: (1) After entering the abdomen, in order to fully expose the operative field, the surgeon spends a lot of time and energy separating the small intestine, unconsciously increasing the surgical time, and there is also a possibility of increasing the risk of secondary damage to the small intestine and its mesentery. (2) During pelvic cavity surgery, in order to slide the small intestine cephalad, it is often necessary to lower the patient's head and raise the feet, which compresses the patient's lungs, affecting the functions of the respiratory and circulatory systems and increasing the difficulty of ensuring anesthesia control and the stability of the surgical process. (3) In situations where it is difficult to expose during laparoscopic surgery, the number of puncture holes may be increased, or the assistant has to continuously hold the small intestine open, increasing the difficulty of the assistant's assistance. (4) If the small intestine is not properly fixed and often slips into the operative field, there is a possibility of damaging the small intestine by thermoelectric surgical operations, such as the operation of an ultrasonic scalpel or an electric scalpel. (5) During the surgical operation, especially when dealing with tumors, the small intestine may be contaminated by tumor cells, violating the principle of tumor - free technology. At the same time, when dealing with the large intestine, bacteria in the intestinal lumen may also contaminate the small intestine.

[0003] Therefore, when performing surgery on the mid- and lower abdomen, especially laparoscopic surgery, a device is needed to isolate the small intestine from the surgical site. This exposes the surgical site, allowing the surgeon to perform the surgery with more ease, thereby shortening the surgical time and reducing complications. [Overview of the project]

[0004] The object of the present invention is to provide an intestinal isolation and protection device, which, after the isolation and protection bag module is released from the outer sleeve, places the small intestine into the isolation and protection bag module, thereby isolating the small intestine from the surgical site, exposing the surgical site, and allowing the surgeon to perform the surgery with ample time. This minimizes surgical time and reduces complications. At the same time, while protecting the small intestine, the device can also reduce the risk of the small intestine becoming contaminated with tumors or bacteria.

[0005] The present invention provides an intestinal isolation and protection device including an isolation and protection bag module, a push module, and a fixing attachment module.

[0006] The above-mentioned push-pull module includes a push-pull rod and an outer sleeve, and the isolation protection bag module is wound and housed inside the outer sleeve. The push-pull module releases the isolation protection bag module from the outer sleeve by pushing with the push-pull rod.

[0007] The above-mentioned fixed attachment module includes a towing wire and a fixing clamp. The towing wire is used to hook the isolation protection bag module, and after the towing wire pulls the isolation protection bag module to the target area, the fixing clamp clamps the towing wire.

[0008] Preferably, the isolation protection bag module includes an isolation protection bag body, the isolation protection bag body has a bag-like net structure, and an opening is provided at the top of the isolation protection bag.

[0009] Preferably, the push module further includes a converging film.

[0010] The convergence membrane is located between the isolation protection bag module and the outer sleeve.

[0011] More preferably, the push module further includes a heat-shrinkable ring fastening member.

[0012] A push-pull handle is installed at one end of the push-pull rod, and a first annular locking groove is installed at the other end of the push-pull rod. The first annular locking groove is fixed to the first opening of the converging membrane by the heat-shrinkable ring tightening member.

[0013] More preferably, a second annular locking groove is provided at one end of the outer sleeve, and the second annular locking groove is fixed to the second opening of the converging film by the heat shrink ring tightening member.

[0014] Preferably, a simulated grip structure is installed at the other end of the outer sleeve.

[0015] Preferably, the push module further includes a seal cap and a gland seal.

[0016] The above-mentioned sealing cap is installed at one end of the outer sleeve and seals the outer sleeve after the isolation protection bag module is placed inside it.

[0017] The above-mentioned gland seal is a silica gel material and is installed at the other end of the outer sleeve. A hole is provided in the middle of the silica gel material, and the diameter of the hole is smaller than the diameter of the push-pull rod.

[0018] Preferably, the fixed attachment module further includes a puncture needle, the puncture needle having a hollow needle tube structure, a sharp needle tip at one end of the puncture needle, and an operating handle at the other end of the puncture needle.

[0019] Preferably, one end of the towing wire has a hook structure, and the other end of the towing wire has an arc-shaped curve.

[0020] Preferably, the fixing clamp is a Robert clamp, and the opening edge of the fixing clamp has a detachable protrusion.

[0021] [Effects of the Invention]

[0022] The intestinal isolation and protection device of the present invention involves rolling up the isolation and protection bag module and storing it in the outer sleeve before use. During use, the isolation and protection bag module is pushed to the outside of the outer sleeve by a push-pull rod in the push module, and then the isolation and protection bag module is hooked by a traction wire in the fixing attachment module. After the traction wire pulls the isolation and protection bag module to the target area, the traction wire is clamped using a fixing clamp. After the isolation and protection bag module is released from the outer sleeve, the small intestine is placed inside the isolation and protection bag module to isolate the small intestine from the surgical site, exposing the surgical site and allowing the surgeon to perform the surgery with ample time, thereby minimizing surgical time and reducing complications. At the same time, the device further reduces the risk of the small intestine being contaminated by tumors or bacteria, based on the premise of protecting the small intestine.

[0041] As shown in Figures 1 to 9, the present invention provides an intestinal isolation and protection device including an isolation and protection bag module 100, a push module 200, and a fixed attachment module 300. The push module 200 includes a push / pull rod 210 and an outer sleeve 220, in which the isolation and protection bag module 100 is wound and stored inside the outer sleeve 220, and the push module 200 releases the isolation and protection bag module 100 from inside the outer sleeve 220 by pushing with the push / pull rod 210. The fixed attachment module 300 includes a pull wire 320 and a fixed clamp 330, in which the pull wire 320 is used to hook the isolation and protection bag module 100, and after the pull wire 320 pulls the isolation and protection bag module 100 to the target area, the fixed clamp 330 clamps the pull wire 320.

[0042] The intestinal isolation and protection device of the present invention stores the isolation and protection bag module 100 rolled up inside the outer sleeve 220 before use. When in use, the isolation and protection bag module 100 is pushed out of the outer sleeve 220 by the push-pull rod 210 inside the push-pull module 200, and then the isolation and protection bag module 100 is hooked by the traction wire 320 inside the fixing attachment module 300. After the traction wire 320 pulls the isolation and protection bag module 100 to the target area, the traction wire 320 is clamped by the fixing clamp 330, and after the isolation and protection bag module 100 is released from the outer sleeve 220, the small intestine is placed inside the isolation and protection bag module 100, thereby isolating the small intestine from the surgical site, exposing the surgical site, and allowing the surgeon to perform the surgery with ample time, thus minimizing surgical time and reducing complications. At the same time, the device also reduces the risk of the small intestine being contaminated by tumors or bacteria, based on the premise of protecting the small intestine.

[0043] The isolation protection bag module 100 includes an isolation protection bag body, which has a bag-like net structure and an opening at the top of the isolation protection bag. After entering the abdominal cavity, the isolation protection bag can be fully expanded and used to contain the free small intestine or other organs that obstruct the surgical field.

[0044] The push-pull module 200 further includes a heat-shrinkable ring fastening member 230, a push-pull handle 211 is provided at one end of the push-pull rod 210, and a first annular locking groove 212 is provided at the other end of the push-pull rod 210, the first annular locking groove 212 is used to fix the converging membrane 240.

[0045] The push module 200 further includes a converging membrane 240, which is located between the isolation protection bag module 100 and the outer sleeve 220. The converging membrane 240 is used to reduce friction between the isolation protection bag module 100 and the wall of the outer sleeve 220 by bundling and securing the wound isolation protection bag module 100 when the isolation protection bag module 100 is loaded into the outer sleeve 220. A second annular locking groove 221 for securing the converging membrane 240 is provided at one end of the outer sleeve 220. The second annular locking groove 221 and the first annular locking groove 212 are engaged with the second and first openings of the converging membrane 240 via a heat shrink ring tightening member 230, respectively, and are used to seal the internal space of the outer sleeve 220 and prevent air leakage after the push module 200 enters the abdominal cavity. Specifically, the heat shrink ring tightening member 230 shrinks and tightens when heated, thereby achieving fixation.

[0046] A simulated grip structure 222 is installed at the other end of the outer sleeve 220, making it easy to grasp.

[0047] The push-pull module 200 further includes a seal cap 223 and a gland seal 224. The seal cap 223 is installed at one end of the outer sleeve 220 and seals the outer sleeve 220 after the isolation protection bag module 100 is housed in the outer sleeve 220. The gland seal 224 is installed at the other end of the outer sleeve 220 and is made of silica gel with a hole in the middle. The diameter of the hole is smaller than the diameter of the push-pull rod 210, and after the push-pull rod 210 is inserted, it serves to position the gland seal and increase the resistance.

[0048] The fixed attachment module 300 further includes a puncture needle 310, which has a hollow needle tube structure, with a sharp needle tip 311 at one end for use in puncturing the abdominal wall, and an operating handle 312 at the other end for easy gripping by the operator.

[0049] One end of the traction wire 320 has a hook structure 321, which makes it easy to hook the isolation protection bag module 100 inside the abdominal cavity, and the other end of the traction wire 320 has an arc-shaped curve, which prevents the traction wire 320 from sliding completely into the abdominal cavity.

[0050] The fixing clamp 330 is a Robert clamp, and the fixing clamp 330 has a removable protrusion 331 on its opening edge, making it easy to use as the Robert clamp can be removed with one hand. After the towing wire 320 has pulled the isolation protection bag module 100 to the target area, the towing wire 320 can be clamped with the fixing clamp 330 to prevent it from slipping, thereby positioning the isolation protection bag module 100.

[0051] The present invention is an intestinal isolation and protection device that isolates the small intestine from the surgical site during mid-lower abdominal, pelvic cavity and retroperitoneal surgeries such as colorectal cancer surgery, uterine and adnexal surgery, vesicoureteral surgery, periaortic lymph node dissection surgery, and retroperitoneal great vessel surgery, thereby reducing the impact of the small intestine on the surgery and simultaneously reducing the risk of contamination of the small intestine by tumors or bacteria.

[0052] As shown in Figure 9, when performing surgeries on the mid-lower abdomen, pelvis, and retroperitoneum, such as rectal and colon cancer surgery, uterine and adnexal surgery, vesicoureteral surgery, periaortic lymph node dissection surgery, and retroperitoneal great vessel surgery, the push module 200 of the intestinal isolation and protection device is inserted into the abdominal cavity through the laparoscopic puncture device 5 or abdominal wall opening, and the isolation and protection bag module 100 is pushed out from the outer sleeve 220 by pushing the push-pull rod 210. Then, using surgical forceps 4, the small intestine free in the mid-lower abdomen is gently placed into the mesh bag, and the edge of the mesh bag is pulled away from the surgical site. By fixing it using the fixation attachment module 300, the surgical field can be quickly exposed, reducing the impact of the small intestine on the surgery, accelerating the progress of the surgery, and simultaneously reducing the risk of contamination of the small intestine with tumors or bacteria, thus providing isolation and protection for the small intestine.

[0053] Finally, it should be explained that the above embodiments are for illustrating the technical methods of the present invention and are not limiting. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art may modify the technical methods described in the above embodiments or make equivalent substitutions for some or all of the technical features therein. However, such modifications or substitutions will not cause the essence of the corresponding technical methods to deviate from the scope of the technical methods of the embodiments of the present invention.
