Description

Technical Field

[0001] The utility model relates to the field of rectal cancer surgery, in particular to a magnetic finger ring for locating the lower resection margin of rectal cancer. Background Art

[0002] Radical rectal cancer resection is the standard surgical procedure for treating rectal cancer. Most rectal cancer patients have a strong desire to preserve their anus. In recent years, anus-preserving surgery (anterior rectal resection) has gradually become the mainstream surgical procedure for radical rectal cancer resection. This procedure not only removes the tumor intestinal tract, but also reconstructs the digestive tract and anastomoses the proximal and distal intestinal tracts, improving the patient's quality of life. However, in order to ensure the quality of radical surgery, the position of the lower resection margin is a key indicator. The latest rectal cancer treatment guidelines mention that a 2cm lower resection margin for rectal cancer is a safe distance, but how to achieve this goal has not yet been uniformly standardized in the industry. Some experts use a good amount of silk thread as a reference to determine the position of the lower resection margin, while others use nano-carbon preoperative colonoscopy injection markers to determine the position of the lower resection margin. The final results are not satisfactory. Accurately locating the lower resection margin of rectal cancer is a difficult problem in the industry. Utility Model Content

[0003] In response to the deficiencies of the existing technology, the utility model provides a magnetic finger ring for locating the lower resection margin of rectal cancer. The magnetic finger ring can be combined with the staff's fingers to accurately locate the position of the lower resection margin, thereby facilitating the operation of radical resection of rectal cancer.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a magnetic finger ring for locating the lower resection edge of rectal cancer, comprising a finger ring with strong magnetism, wherein the inner side of the finger ring is embedded with a circle of inner-opening Halfen grooves facing outward, and the vertical section of the Halfen groove is an outward-lying T-shape, and a circle of suction cups that cooperate with the outer surface of the finger are fixedly arranged circumferentially in the Halfen groove.

[0005] As a preferred technical solution, the suction cup includes a leather cup whose inner side is adsorbed and cooperates with the outer surface of the finger. A horizontal cylinder is provided on the rear side of the leather cup. The inner end of the cylinder is fixedly connected to the rear side of the leather cup. The outer side of the cylinder extends outward from the opening in the Haven groove and a circular fixing block is fixed on the outer end.

[0006] As a preferred technical solution, the fixing block is detachably connected to the vertical portion inside the Halfen trough.

[0007] As a preferred technical solution, the number of the suction cups is at least 8.

[0008] As a preferred technical solution, the detachable outer cover of the ring is provided with a protective cover.

[0009] As a preferred technical solution, the protective cover comprises an elastic film-shaped cover that wraps the finger ring from the outside to the inside. The cover is annular with an inner opening, and a circle of elastic rubber rings are fixed to the edges of the cover on the upper and lower sides of the inner opening.

[0010] Compared with the existing technology, the present invention provides a magnetic finger ring for locating the lower resection margin of rectal cancer, which has the following beneficial effects:

[0011] 1. The utility model has a half-groove with an inner opening embedded in the inner side of the ring. The vertical section of the half-groove is an outwardly lying T-shape. A circle of suction cups that cooperate with the outer surface of the finger is fixedly provided circumferentially in the half-groove. When in use, first use a tape measure to measure the position of the operator's right index finger from the fingertip to the base of the finger 2 cm away, mark the circumference with a marking pen, then put the magnetic ring on the operator's right index finger, ensure that the distal edge of the magnetic ring is aligned with the marked line, put on latex gloves, apply lubricant, and insert the index finger into the patient's anus for rectal examination. When the operator's index fingertip touches the lower edge of the rectal tumor base, the digital examination is paused, maintaining the index finger's position. Simultaneously, the laparoscopic surgeon touches the tip of the laparoscopic separating forceps through the rectal wall near the magnetic ring. When the separating forceps are attracted to the magnetic ring and fixed at a certain point, that position is the ideal lower surgical margin. The separating forceps are used to mark the intestinal wall at that location. The laparoscopic surgeon then proceeds to complete the tumor removal procedure according to the laparoscopic rectal cancer surgery procedure. The index finger wearing the magnetic ring is then removed, the latex gloves are removed, the magnetic ring is removed, and the device is disinfected for future use.

[0012] 2. The utility model comprises a suction cup including an inner side of a leather cup which is adapted to be adsorbed and fitted with the outer surface of the finger, a transverse cylinder being provided on the rear side of the leather cup, an inner end of the cylinder being fixedly connected to the rear side surface of the leather cup, an outer side of the cylinder extending outward from an opening in the Haven groove and a circular fixing block being fixed on the outer end thereof, and when in use, the fixing block can be clamped and fixed in the vertical groove in the Haven groove, and the suction cup can be easily disassembled and replaced later if it is damaged.

[0013] 3. The utility model provides a protective cover that is detachable from the outer ring. The protective cover comprises an elastic film-shaped cover that wraps around the ring from the outside to the inside. The cover is annular with an inner opening, and an elastic rubber ring is fixed to the upper and lower edges of the inner opening. When in use, the protective cover can wrap and protect the ring, preventing it from slipping, bumping, and being damaged. The protective cover is also detachable for cleaning and disinfection. The elastic rubber ring can be tightened on the inside to prevent it from slipping. BRIEF DESCRIPTION OF THE DRAWINGS

The outer side of the cylinder 32 extends outward from the inner opening of the Hafen groove 2 and a circular fixing block 33 is fixed on the outer end.

[0024] The fixing block 33 is detachably connected to the vertical portion inside the Halfen trough 2. The fixing block 33 can be vertically clamped in the vertical groove inside the Halfen trough 2.

[0025] The number of the suction cups 3 is at least 8. In this embodiment, the number of the suction cups 3 is 8.

[0026] To use the device, first use a tape measure to measure the 2 cm distance from the tip to the base of the operator's right index finger. Mark the circumference with a marker pen. Then, place the strong magnetic ring 1 on the operator's right index finger (the suction cup provides protection), ensuring the distal edge of the ring 1 is aligned with the marked line. Wearing latex gloves and applying lubricant, insert the index finger into the patient's anus for a digital rectal examination. When the operator's index fingertip touches the lower edge of the rectal tumor base, the examination is paused, maintaining the index finger in place. Simultaneously, the laparoscopic surgeon touches the tip of the laparoscopic dissecting forceps through the rectal wall near the magnetic ring. When the dissecting forceps are attracted to the magnetic ring and fixed at a certain point, this position is the ideal lower surgical margin. The dissecting forceps are then used to mark the intestinal wall. The operator can then proceed with tumor resection according to the laparoscopic rectal cancer surgery procedure. The index finger wearing the ring 1 is then removed, the latex gloves are removed, the ring 1 is removed, and the device is disinfected for future use. The fixing block 33 can be clamped and fixed in the vertical groove in the Halfen slot 2, and the suction cup 3 can be easily disassembled and replaced after being damaged. Example 2
