Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a medical endometriosis surgery guide. Background Technology

[0002] A medical endometriosis surgical guide is a highly specialized surgical instrument concept, often referring to specialized instruments developed by hospitals or research institutions for specific surgical challenges. Specifically, it is an auxiliary tool used in laparoscopic surgery for deep invasive endometriosis to accurately locate deep lesions that are difficult to see with the naked eye in real time, guiding surgical resection and maximizing the protection of critical organs such as the intestines.

[0003] Application No. 201720932064.4 discloses a medical endometriosis surgical guide, comprising an insert with an arc-shaped portion at its front end and a length adjustment rod installed at the rear end of the insert. The length adjustment rod is adjustable in length relative to the insert. The insert and the length adjustment rod are respectively provided with interconnected vent holes at their centers to form a ventilation channel for checking colonic integrity. This patented guide has a simple structure and is easy to use. It accurately indicates the location of DIE lesions during surgery, facilitating surgical procedures, reducing intraoperative bowel damage, and improving patient prognosis. It can play an important role in laparoscopic surgery for DIE and has broad application prospects in related fields.

[0004] Although the length of the insert can be adjusted by the length adjustment rod, the angle of the insert is fixed as a straight line. When using a straight rod or a fixed angle rod to forcibly pass through the bend of the rectum, it is easy to bruise or tear the rectal mucosa, increasing the treatment risk. Summary of the Invention

[0005] The purpose of this invention is to provide a medical endometriosis surgical guide to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a medical endometriosis surgical guide, comprising a base rod, an insertion rod, and a base. The insertion rod is connected to the bottom end of the outer wall of the base rod, and the base is connected to the top end of the outer wall of the base rod. A threaded rod is provided inside the base, and a threaded cylinder is threadedly connected to the top end of the outer wall of the threaded rod. A first threaded pin is fixedly connected to the middle of the top end of the insertion rod, and a threaded hole corresponding to the first threaded pin is opened inside the bottom end of the base rod. A second threaded pin is fixedly connected to the middle of the bottom end of the base, and a threaded groove corresponding to the second threaded pin is opened inside the top end of the base rod. The threaded rod and threaded cylinder are telescopic, allowing adjustment of the insertion length of the insertion rod; both the base and the insertion rod are modularly designed for quick assembly and replacement, and the outer wall of the insertion rod can be fitted with anti-slip texture. A fixing pin is rotatably connected to one side of the bottom end of the threaded rod, and a positioning pin is slidably connected to the other side of the bottom end of the threaded rod. The outer wall of the fixing pin is fixedly connected to the inner wall. The threaded rod can rotate along the fixing pin to adjust the angle of the insertion rod and adapt to the physiological curvature of the rectum; the positioning pin is used to lock the threaded rod.

[0007] Preferably, a sealing plug is installed at the bottom end of the threaded cylinder, the base has a "U" shaped structure, the insertion rod and the first threaded pin have a "T" shaped cross section, and a limiting hole corresponding to the positioning pin is opened inside the bottom end of the threaded rod, and the positioning pin is hexagonal.

[0008] By rotating the threaded cylinder, the total length of the cylinder and the threaded rod is increased, thereby adjusting the insertion depth of the insertion rod.

[0009] Preferably, a slider is slidably connected inside the base, and a cover plate is fixedly connected to one side of the outer wall of the slider, and a transmission plate is fixedly connected to the other side of the outer wall of the slider. The slider, the cover plate and the transmission plate form a "U" shaped structure.

[0010] Pressing the cover plate moves the slider, which in turn moves the transmission plate and moves the positioning pin until the hexagonal positioning pin disengages from the bottom of the threaded rod, thus releasing the lock on the threaded rod.

[0011] Preferably, a spring is fixedly connected to the middle of the outer wall of the transmission plate, and one side of the outer wall of the spring is fixedly connected to the inner wall of the base. The slider, the transmission plate and the spring form an elastic telescopic mechanism.

[0012] The spring returns the hexagonal locating pin to the bottom of the threaded rod, thereby locking the threaded rod.

[0013] As can be seen from the above, the medical endometriosis surgical guide provided by the present invention has the following beneficial effects.

[0014] 1. Modular assembly and threaded connection design allow for independent and quick replacement of components without scrapping the entire instrument; and the insertion rod with anti-slip texture prevents the instrument from slipping during critical steps.

[0015] 2. The press-to-unlock, rotation-to-adjust, and spring-reset-lock mechanism allows for quick and flexible angle adjustment during the procedure, ensuring a secure lock after rotation without any risk of loosening. Furthermore, the adjustable angle is combined with the physiological curvature of the rectum, reducing the risk of tissue traction or puncture injury caused by forced instrument entry.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-6 The present invention provides a technical solution: a medical endometriosis surgical guide, comprising a base rod 1, an insertion rod 2 and a base 3. The insertion rod 2 is connected to the bottom end of the outer wall of the base rod 1, and the base 3 is connected to the top end of the outer wall of the base rod 1. A threaded rod 4 is provided inside the base 3, and a threaded cylinder 5 is threadedly connected to the top end of the outer wall of the threaded rod 4. A first threaded pin 6 is fixedly connected to the middle of the top end of the insertion rod 2, and a threaded hole corresponding to the first threaded pin 6 is opened inside the bottom end of the base rod 1. A second threaded pin 7 is fixedly connected to the middle of the bottom end of the base 3, and a threaded groove corresponding to the second threaded pin 7 is opened inside the top end of the base rod 1. The threaded rod 4 and the threaded cylinder 5 are telescopic, allowing adjustment of the insertion length of the insertion rod 2; both the base 3 and the insertion rod 2 are modularly designed for quick assembly and replacement, and the outer wall of the insertion rod 2 can be fitted with anti-slip texture. A fixing pin 8 is rotatably connected to one side of the bottom end of the threaded rod 4, and a positioning pin 9 is slidably connected to the other side of the bottom end of the threaded rod 4. The outer wall of the fixing pin 8 is fixedly connected to the inner wall. The threaded rod 4 can rotate along the fixing pin 8 to adjust the angle of the insertion rod 2 to adapt to the physiological curvature of the rectum; the positioning pin 9 is used to lock the threaded rod 4.

[0020] A sealing plug is installed at the bottom of the threaded cylinder 5. The base 3 has a "U" shaped structure. The cross-section of the insertion rod 2 and the first threaded pin 6 has a "T" shaped structure. The bottom end of the threaded rod 4 has a limiting hole corresponding to the positioning pin 9, and the positioning pin 9 is hexagonal. A slider 10 is slidably connected inside the base 3. A cover plate 11 is fixedly connected to one side of the outer wall of the slider 10, and a transmission plate 12 is fixedly connected to the other side of the outer wall of the slider 10. The slider 10, the cover plate 11 and the transmission plate 12 form a "U" shaped structure. A spring 13 is fixedly connected to the middle of the outer wall of the transmission plate 12, and one side of the outer wall of the spring 13 is fixedly connected to the inner wall of the base 3. The slider 10, the transmission plate 12 and the spring 13 form an elastic telescopic mechanism.

[0021] For specific implementation, please refer to Figure 2 and Figure 3 The guide adopts a modular design. During assembly, the No. 1 threaded pin 6 at the top of the insertion rod 2 is screwed into the bottom of the base rod 1, and then the No. 2 threaded pin 7 at the bottom of the base 3 is screwed into the top of the base rod 1 to complete the overall assembly. This makes it easy for users to quickly replace damaged parts. In addition, the insertion rod 2 with anti-slip texture on the outer wall can be selected to increase friction and prevent slippage when lifting the lesion during the operation, thereby improving the stability of the positioning operation.

[0022] See Figure 1 and Figure 4 Rotating the threaded cylinder 5 changes its relative position to the threaded rod 4, thereby lengthening or shortening the total combined length of the two, thus enabling precise and continuous adjustment of the insertion depth of the insertion rod 2. See Figure 5 and Figure 6 Pressing the cover plate 11 causes the slider 10 and the transmission plate 12 linked with it to move. When the transmission plate 12 moves, it compresses the spring 13 and causes the hexagonal positioning pin 9 to disengage from the corresponding hole at the bottom of the threaded rod 4, thereby releasing the rotation lock on the threaded rod 4. In the unlocked state, the tilt angle can be adjusted by rotating the threaded rod 4 around the fixed pin 8 as the axis. After adjusting to the desired angle, release the cover plate 11; at this time, the compressed spring 13 rebounds, driving the transmission plate 12 to reset, thereby pushing the hexagonal positioning pin 9 to re-insert into the new hole at the bottom of the threaded rod 4 to achieve locking; the angle adjustment function enables the insertion rod 2 to adapt to the physiological curvature of the rectum, reducing the risk of damage to the rectal mucosa during the operation.

[0023] Modular assembly and threaded connection design allow for independent and quick replacement of components without the need to scrap the entire instrument; and the insertion rod 2 with anti-slip texture prevents the instrument from slipping out during critical steps.

[0024] The mechanism of pressing to unlock, rotating to adjust, and spring 13 to reset and lock allows for quick and flexible angle adjustment during the operation, and ensures that the lock is locked after rotation without the risk of loosening. The adjustable angle is combined with the physiological curvature of the rectum, which reduces the risk of tissue traction or puncture caused by the forced entry of instruments.

[0025] In practice, the surgeon holds the tail end of the threaded cylinder 5 and aligns the arc-shaped part of the insertion rod 2 with the patient's anus. Under laparoscopic monitoring, the insertion rod 2 is slowly and gently inserted into the rectum through the anus. During insertion, the axis of the insertion rod 2 is kept aligned with the physiological course of the rectum, avoiding hard bending, until the narrowed part of the insertion rod 2 is engaged at the anus, at which point insertion is stopped. The insertion depth of the insertion rod 2 is then adjusted to suit the lesion location, and the angle of the insertion rod 2 is adjusted to suit the physiological curvature of the rectum. Then, the surgeon uses laparoscopic instruments, guided by the positioning provided by the arc-shaped part of the insertion rod 2, to precisely remove the DIE lesion. If the lesion location shifts slightly during the operation, the depth and angle can be repeatedly fine-tuned to ensure the positioning effect.

[0026] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made to the technical solutions and inventive concepts of the present invention should all be covered within the scope of protection of the present invention.
