Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a surgical aid device for bile duct cancer. Background Technology

[0002] Cholangiocarcinoma refers to malignant tumors originating from the extrahepatic bile ducts, including the bile ducts from the porta hepatis to the lower end of the common bile duct. Its etiology may be related to diseases such as bile duct stones and primary sclerosing cholangitis. The most effective treatment for cholangiocarcinoma usually involves removing the surrounding tissues and organs to minimize the risk of recurrence and metastasis. This surgery typically requires general anesthesia and open surgery because it necessitates the removal of part or all of the bile ducts and liver.

[0003] In the prior art, doctors need to maintain the same posture for a long time when performing bile duct surgery, which is very tiring and affects the progress of the surgery. Based on these problems, Chinese patent CN209770554U discloses a surgical auxiliary device for bile duct cancer in general surgery. When in use, it can be fixed to the side of the operating table. During the operation, the doctor can adjust the column to a suitable height and then rotate the support plate to adjust to a suitable angle. The arm can be placed on the support plate to relieve the doctor's fatigue. The telescopic plate is slidably connected to the support plate, which can adjust the length of the support plate. The baffle can block the doctor's elbow and prevent the elbow from slipping downwards.

[0004] The height adjustment range of this surgical aid is very limited. The placement area for the arm and elbow is always located above the column. Therefore, when the patient's body is positioned diagonally below the column, there is a large distance between the doctor's elbow and the patient's body, which not only affects the normal progress of the surgery but also causes the doctor to become fatigued quickly.

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A surgical aid for bile duct cancer includes a square shell. A clamping mechanism is installed at the top of the outer wall of the square shell, which can fix the aid to the edge of the operating table. A shaft is fixedly connected to the center of both sides of the inner wall of the square shell. A gear ring is rotatably connected to the outer wall of the shaft. A first gear rack is slidably connected to the rear end of the inner wall of the square shell, and a second gear rack is slidably connected to the front end of the inner wall of the square shell. The tooth grooves on the opposite surfaces of the first and second gear racks mesh with the teeth on the outer wall of the gear ring. Slide grooves are formed on both the front and rear surfaces of the inner wall of the square shell. Hollow sliders are fixedly connected to the opposite surfaces of the first and second gear racks. The outer walls of the hollow sliders are slidably connected to the inner walls of the slide grooves. A placement mechanism for placing the doctor's arm is installed at the top of the first gear rack, and a pedal is fixedly connected to the bottom of the second gear rack.

[0008] As a further description of the above technical solution:

[0009] The clamping mechanism includes a clamping plate, a clamping groove, a threaded ring, a threaded column, a first rotating shaft, and a clamping piece. The clamping plate is fixedly connected to the top of the outer wall of the square shell, and a clamping groove is provided at the center of the rear end face of the clamping plate.

[0010] As a further description of the above technical solution:

[0011] A threaded ring extends through one bottom end of the clamping plate. A threaded post is threadedly connected to the inner wall of the threaded ring. A first rotating shaft is fixedly connected to the top of the threaded post. A clamping piece is rotatably connected to the top of the first rotating shaft. One outer wall of the clamping piece is slidably connected to one inner wall of the clamping groove.

[0012] As a further description of the above technical solution:

[0013] The placement mechanism includes a hollow plate, a through hole, a spring body, a spring rod, a movable plate, a sliding plate, a cavity, a pad, a second rotating shaft, a through-arm tube, and a sponge sleeve. The top of the first gear rack is fixedly connected to the hollow plate, and both ends of the hollow plate are provided with through holes running from front to back.

[0014] As a further description of the above technical solution:

[0015] The inner wall of each through hole is fitted with a spring body, the inner wall of each spring body is fitted with a spring rod, the rear end of each spring rod is fixedly connected to a movable plate, and the top of the movable plate is fixedly connected to a sliding plate.

[0016] As a further description of the above technical solution:

[0017] The top center of the skateboard has a through cavity running vertically through it. A pad is fixedly connected to the bottom of the inner wall of the cavity. A second rotating shaft is fixedly connected to the top center of the pad. A through-arm tube is rotatably connected to the top of the second rotating shaft.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] (1) When the second gear slides down, the first gear slides up. When the second gear slides up, the first gear slides down. The top of the first gear is equipped with a placement mechanism, and the bottom of the second gear is equipped with a pedal. Therefore, the doctor can control the height of the arm placement mechanism by stepping on the pedal. Since the doctor's fingers can touch the top surface of the operating table, the distance between the doctor's elbow and the patient's body is closer, which not only improves the safety of the operation, but also reduces the doctor's fatigue.

[0022] (2) By setting up a sponge sleeve, the doctor's forearm can be protected. By setting up a simple connection between the sponge sleeve and the arm tube, the sponge sleeve can be installed and removed more conveniently and quickly. By setting up a second pivot, the doctor can twist back and forth when putting the forearm into the arm tube, which facilitates the normal operation of the surgery. By setting up a connection structure between the slide plate and the hollow plate, the flexibility of the arm placement structure can be improved, which makes it easier for the doctor to perform surgery on different parts of the human body. Since the elastic coefficient of the spring body is small, the resistance to the doctor's arm extension is also small. Attached Figure Description

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0033] Reference Figure 1-5This utility model provides an embodiment of a surgical aid device for bile duct cancer, comprising a square shell 1. A clamping plate 21 is fixedly connected to the top of the outer wall of the square shell 1. A square through hole is formed at one top end of the clamping plate 21. The top of the outer wall of the square shell 1 is installed in the square through hole inside the clamping plate 21. The top surface of the square shell 1 and the top surface of the clamping plate 21 are both set on the same horizontal plane. Openings are provided at the top and bottom of the square shell 1. A clamping groove 22 is formed at the center of the rear end face of the clamping plate 21. The clamping groove 22 can be fitted onto the edge of the operating table. A threaded ring 23 is passed through one bottom end of the clamping plate 21. The internal space of the threaded ring 23 communicates with the internal space of the clamping groove 22. The inner wall of the ring 23 is threaded with a threaded post 24. The top of the threaded post 24 is fixedly connected to a first rotating shaft 25. The top of the first rotating shaft 25 is rotatably connected to a clamping piece 26. One side of the outer wall of the clamping piece 26 is slidably connected to one side of the inner wall of the clamping groove 22. The rotating threaded post 24 can move up and down on the inner wall of the threaded ring 23. When the rotating threaded post 24 moves upward, the clamping piece 26 will also slide upward, thereby clamping the edge of the operating table. It also serves to fix the entire auxiliary device on the operating table. By setting the clamping plate 21, clamping groove 22, threaded ring 23, threaded post 24, first rotating shaft 25 and clamping piece 26, the clamping mechanism 2 can be formed.

[0034] A shaft 3 is fixedly connected to the center of both sides of the inner wall of the square shell 1. A gear ring 4 is rotatably connected to the outer wall of the shaft 3. A first gear rack 5 is slidably connected to the rear end of the inner wall of the square shell 1, and a second gear rack 6 is slidably connected to the front end of the inner wall of the square shell 1. The tooth grooves on the opposite surfaces of the first gear rack 5 and the second gear rack 6 mesh with the teeth on the outer wall of the gear ring 4. It is worth noting that when the second gear rack 6 slides downward, the first gear rack 5 will slide upward, and vice versa. The first gear rack 5 can extend from the top opening of the square shell 1, and the second gear rack 6 can extend from the bottom opening of the square shell 1. The front and rear faces of the inner wall of the square shell 1 are provided with sliding grooves 7. The opposite faces of the first gear rack 5 and the second gear rack 6 are fixedly connected with hollow sliders 8. The hollow sliders 8 are provided with through holes running vertically. The outer walls of the hollow sliders 8 are slidably connected to the inner walls of the sliding grooves 7. By setting the connection structure between the hollow sliders 8 and the sliding grooves 7, it is beneficial to improve the stability of the first gear rack 5 and the second gear rack 6 during the up and down sliding process.

[0035] A hollow plate 91 is fixedly connected to the top of the first gear rack 5. Both ends of the hollow plate 91 have through holes 92 extending from front to back. A spring body 93 is fitted onto the inner wall of each through hole 92, and a spring rod 94 is fitted onto the inner wall of each spring body 93. One end of the spring rod 94 extends from the rear opening of the through hole 92. A movable plate 95 is fixedly connected to the rear end of the spring rod 94, and a sliding plate 96 is fixedly connected to the top of the movable plate 95. The spring body 93 has a relatively low elastic coefficient, but it can pull the spring rod 94 into the through hole 92. At this time, the distance between the opposite surfaces of the movable plate 95 and the hollow plate 91 gradually decreases, while the sliding plate 96 slowly returns to its original position. The bottom surface can slide closely against the top surface of the hollow plate 91. A through-cavity 97 is provided at the top center of the slide plate 96. A pad 98 is fixedly connected to the bottom end of the inner wall of the cavity 97. A second rotating shaft 99 is fixedly connected to the top center of the pad 98. The top of the outer wall of the second rotating shaft 99 extends from the opening at the top of the cavity 97. A through-arm tube 910 is rotatably connected to the top of the second rotating shaft 99. A sponge sleeve 911 is fitted onto the inner wall of the through-arm tube 910. By setting the through-arm tube 910, the doctor's forearm can be placed, and the doctor's palm can extend from the through-arm tube 910. Notably, the doctor's fingers can touch the top surface of the operating table. The foam sleeve 911 protects the surgeon's forearm. The simple connection between the foam sleeve 911 and the arm-penetrating tube 910 makes the installation and removal of the foam sleeve 911 more convenient and quick. The second pivot 99 allows the surgeon to twist and turn the forearm inside the arm-penetrating tube 910, facilitating the procedure. The connection between the sliding plate 96 and the hollow plate 91 enhances the flexibility of the arm placement structure, allowing the surgeon to operate on different parts of the body. Because the spring body 93 has a low elastic coefficient, it provides less resistance to the surgeon's arm extension. The hollow plate 91, through-hole 92, and spring body are all included in this design. 93, spring rod 94, movable plate 95, sliding plate 96, cavity 97, pad 98, second rotating shaft 99, arm tube 910, and sponge sleeve 911 can form the placement mechanism 9. The bottom of the second gear rack 6 is fixedly connected to a pedal 10, and the doctor can control the height of the arm placement mechanism 9 by stepping on the pedal 10. The top and bottom center of the inner wall of the slide groove 7 are fixedly connected to a slide rod 11. One end of the outer wall of the slide rod 11 is slidably connected to the inner wall of the hollow slider 8, and the other end of the outer wall of the slide rod 11 is fitted with a return spring 12. By setting the return spring 12, the hollow slider 8 can be pushed, so that the first gear rack 5 and the second gear rack 6 can be quickly reset.

[0036] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
