Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a rectal traction and fixation device. Background Technology

[0002] During low rectal cancer surgery, the narrow pelvis of patients, especially men, can lead to insufficient exposure of the surgical field, causing the rectum to protrude and obstruct the view. To avoid this, surgical assistants typically use long forceps or forceps to lift the bowel, creating tension to facilitate the surgeon's operation. However, as assistants become more skilled, they often transition into becoming surgeons themselves. A surgeon's career involves many assistants, each initially lacking proficiency. Furthermore, the long forceps or forceps used in laparoscopy are relatively small, limiting their grip area and making it easy to tear or bleed the bowel.

[0003] Currently, during surgery, a gauze strip is usually wrapped around the rectum once, and the surgical assistant can hold both ends and pull the intestinal tube. This operation can avoid damage to the intestinal tube. However, because the gauze strip is not very stable, it is easy to slip with the intestinal tube during traction. Also, after the gauze strip is wrapped, its opening faces to one side, making it difficult to change the direction of traction during surgery.

[0004] Therefore, there is an urgent need for a rectal traction and fixation device to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to provide a rectal traction and fixation device to solve the above-mentioned technical problems.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a rectal traction and fixation device, comprising a rubber ring, wherein a first convex tooth, a second convex tooth, a third convex tooth and a fourth convex tooth are evenly distributed from the head to the tail of the rubber ring, and the rubber ring is integrally connected with the first convex tooth, the second convex tooth, the third convex tooth and the fourth convex tooth; and a length adjustment structure is provided at the tail of the rubber ring.

[0007] By adopting the above technical solution, when using this device, the rubber ring is placed into the patient's abdomen through the incision made by the trocar, wrapped around the rectum once, and then the first protrusion is matched with the length adjustment structure. Subsequently, according to the direction of traction, one of the first, second, third, or fourth protrusions of this device is grasped with long forceps or explosive forceps to pull the rectum away, making the surgical field of low rectal cancer clearer and the exposure more sufficient, so as to facilitate the surgeon's operation.

[0008] The present invention is further configured such that: the length adjustment structure is a length adjustment hole, and the size of the first protruding tooth is adapted to the length adjustment hole.

[0009] The invention is further configured such that: the inner diameter of the rubber ring is adjusted by the length adjustment hole and the first protruding tooth; when the first protruding tooth is connected to the length adjustment hole at the very end of the rubber ring, the inner diameter of the rubber ring is at most 4 cm; when the first protruding tooth is connected to the length adjustment hole furthest from the end, the inner diameter of the rubber ring is at least 2 cm.

[0010] By adopting the above technical solution, the rectal diameter varies among different patients. The rectal diameter of an adult is usually 2-4 cm. Therefore, the device is designed to be adjustable within a diameter range of 2-4 cm to ensure that it can be used for different patients. In this device, the adjustment within the above range can be achieved by inserting the first protruding tooth into the length adjustment hole at different positions.

[0011] The present invention is further configured such that: the length adjustment structure is a length adjustment caliper, and the size of the first protruding tooth is adapted to the length adjustment caliper.

[0012] The present invention is further configured such that: the length adjustment caliper includes a groove and a one-way buckle, the one-way buckle dividing the groove into a small area that can accommodate the first protruding tooth.

[0013] The present invention is further configured such that: the one-way buckle is divided into a rotating area and a fixed area, and a hinge is connected between the rotating area and the fixed area; the hinge includes a first connecting groove, a second connecting groove and a connecting rod, and the first connecting groove is rotatable relative to the second connecting groove.

[0014] The invention is further configured such that: the inner diameter of the rubber ring is adjusted by a length adjustment caliper and a first protruding tooth; when the first protruding tooth is at the end of the length adjustment caliper, the inner diameter of the rubber ring is at most 4 cm; when the first protruding tooth is at the head of the length adjustment caliper, the inner diameter of the rubber ring is at least 2 cm.

[0015] By adopting the above technical solution, the diameter of the device is adjusted using length adjustment calipers. The first protruding tooth is inserted to the very end, and then, according to the diameter of the patient's rectum, the first protruding tooth is pulled to position it appropriately in the slot, facilitating rectal traction. Similarly, to ensure that the needs of different patients are met, the adjustable range of the rubber ring diameter remains 2-4 cm.

[0016] The present invention is further configured such that the length adjustment structure is an adhesive surface.

[0017] By adopting the above technical solution, the adhesive surface is preferred among the three adjustment structures. When preparing this device, a thin film can be covered on the adhesive surface, and the film can be torn off before use.

[0018] The present invention is further configured such that the width of the rubber ring is 1cm and the thickness is 0.05-0.1cm.

[0019] The present invention is further configured such that the lengths of the first convex tooth, the second convex tooth, the third convex tooth, and the fourth convex tooth are 0.3-0.5 cm.

[0020] By adopting the above technical solution, the thickness of the rubber ring plus the height of the protrusion is at most 1.2cm. The wound caused by the puncture is usually about 1.5cm in diameter. This height and thickness make it easier to insert the device into the patient's abdominal cavity through the wound. At the same time, since the height of its protrusion is higher than the thickness of the rubber ring, and at least 0.2cm more, the assistant can easily clamp it when using long forceps or pliers for traction.

[0021] The present invention is further configured such that the rubber ring is made of rubber, latex, silicone, and other non-metallic materials with elastic deformation capabilities.

[0022] By adopting the above technical solution, the rubber ring has a certain elastic deformation ability, which can wrap around the rectum well, and at the same time it will not damage the rectum, making the traction process safer.

[0023] In summary, the present invention has the following beneficial effects: When using this device, the rubber ring is inserted into the patient's abdomen through the incision made by the trocar, wrapped around the rectum once, and then the first protrusion is matched with the length adjustment structure. Subsequently, depending on the direction of traction, one of the first, second, third, or fourth protrusions of the device is used with long forceps or burst forceps to pull the rectum away, making the surgical field for low rectal cancer surgery clearer and more fully exposed, facilitating the surgeon's operation. It can effectively help the assistant to achieve rectal traction during surgery without directly using long forceps or burst forceps to clamp the rectum for traction, avoiding situations such as rectal tearing or rectal bleeding due to the assistant's lack of operation skills.

[0031] The following is combined with Figure 1-6 The present invention will be described in further detail below.

[0032] Example 1: A rectal traction and fixation device includes a rubber ring 1, which has a width of 1 cm and a thickness of 0.05-0.1 cm. The rubber ring 1 has a first tooth 2, a second tooth 3, a third tooth 4, and a fourth tooth 5 evenly distributed from its head to its tail. The rubber ring 1 is integrally connected to the first tooth 2, the second tooth 3, the third tooth 4, and the fourth tooth 5. The length of the first tooth 2, the second tooth 3, the third tooth 4, and the fourth tooth 5 is 0.3-0.5 cm. The rubber ring 1 is made of rubber, latex, silicone, or other non-metallic materials with elastic deformation capabilities. A length adjustment structure is provided at the tail of the rubber ring 1.

[0033] The length adjustment structure is a length adjustment hole 6, and the size of the first protruding tooth 2 is adapted to the length adjustment hole 6. The inner diameter of the rubber ring 1 is adjusted through the length adjustment hole 6 and the first protruding tooth 2. When the first protruding tooth 2 is connected to the length adjustment hole 6 at the far end of the rubber ring 1, the inner diameter of the rubber ring 1 is at most 4 cm. When the first protruding tooth 2 is connected to the length adjustment hole 6 furthest from the far end, the inner diameter of the rubber ring 1 is at least 2 cm.

[0034] Example 2: This example differs from Example 1 in that the length adjustment structure is a length adjustment caliper 7, and the size of the first protruding tooth 2 is adapted to the length adjustment caliper 7. The length adjustment caliper 7 includes a slot 8 and a one-way buckle 9, and the one-way buckle 9 divides the slot 8 into a small area that can accommodate the first protruding tooth 2. The one-way buckle 9 is divided into a rotating area 15 and a fixed area 14, and a hinge 10 is connected between the rotating area 15 and the fixed area 14. The hinge 10 includes a first connecting groove 11, a second connecting groove 12, and a connecting rod, and the first connecting groove 11 can rotate relative to the second connecting groove 12.

[0035] The inner diameter of the rubber ring 1 is adjusted by the length adjustment caliper 7 and the first tooth 2. When the first tooth 2 is at the end of the length adjustment caliper 7, the inner diameter of the rubber ring 1 is at most 4 cm. When the first tooth 2 is at the head of the length adjustment caliper 7, the inner diameter of the rubber ring 1 is at least 2 cm.

[0036] Example 3: The difference between this example and Example 1 is that the length adjustment structure is an adhesive surface 16. An adhesive surface 16 is provided on the inner side of the tail of the rubber ring 1. During manufacturing, a thin film can be covered on the outside of the adhesive surface 16. When using, the film can be torn off.

[0037] Working principle: When using this device, the rubber ring 1 is inserted into the patient's abdomen through the incision made by the trocar, and wrapped around the rectum once. Then, the first protrusion 2 is matched with the length adjustment structure. Subsequently, depending on the direction of traction, one of the first protrusion 2, second protrusion 3, third protrusion 4, or fourth protrusion 5 of the device is used to pull the rectum away, making the surgical field of low rectal cancer clearer and more fully exposed, facilitating the surgeon's operation. It can effectively help the assistant to achieve rectal traction during surgery without directly using long forceps or forceps to clamp the rectum for traction, avoiding situations such as rectal tearing or rectal bleeding due to the assistant's lack of operation skills.
