Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a medical fishbone wire for lifting and pulling. Background Art

[0002] During surgical operations, especially laparoscopic digestive tract operations such as tumor resection and digestive tract reconstruction, the exposure of the surgical field is extremely demanding. In order to fully expose the surgical area, doctors often need to lift and pull adjacent organs such as the liver, diaphragmatic angle, and uterus. Such operations can not only better display the surgical site and provide doctors with a clear operating space, but also effectively reduce the difficulty of the operation and improve the success rate of the operation.

[0003] However, although traditional lifting and pulling methods, such as suturing, knotting fixation, and instrument pulling, can meet surgical needs to a certain extent, they also have many shortcomings. First, the exposure effect of these methods is often not ideal and may not provide doctors with sufficient vision. Secondly, these methods are relatively cumbersome to operate, which not only increases the time of the operation, but also may affect the efficiency of the operation. In addition, the traditional methods are not flexible enough to adjust the pulling force, which can easily cause accidental damage to adjacent organs; therefore, it is necessary to explore safer, more efficient, and more flexible lifting and pulling methods to improve the effect of abdominal surgery and the postoperative recovery of patients.

[0009] The two ends of the fishbone wire are provided with suture needles and gaskets provided by the fishbone wire, and the tail end of the suture needle is connected to the fishbone wire, and there is no need to thread the needle;

[0010] Furthermore, the length of the herringbone wire is about 10-20 cm, and the length of the first exposed section between the suture needle and the barb area is 2 cm.

[0011] Furthermore, the included angle between the barb area on the fishbone wire and the first exposed section is 100°, and the direction of the barb area is consistent with the advancing direction of the suture needle, and the length of the barb is about 1.5 mm.

[0012] Furthermore, the fishbone wire is a straight structure, with a suture needle and a fishbone wire gasket at both ends respectively, and one end of the fishbone wire is inserted into the suture needle, and the length of the second exposed section between the fishbone wire gasket and the barb area is 3 cm. When the fishbone wire 2 is arranged in a combination of several roots, the second exposed section is sleeved with the attached gasket. If no combination is required, there is no need to add the attached gasket.

[0013] The external fixing gasket is a rounded square, and has a first hole at the center of the external fixing gasket. The diameter of the first hole is 2 mm, and the shape of the first hole is circular.

[0014] The fishbone wire is a soft wire structure that can be bent into a U-shaped structure.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1: Please refer to Figures 1 to 5 , the utility model provides a technical solution:

[0028] A medical herringbone wire for lifting and pulling comprises a suture needle 1, a herringbone wire 2, an in vitro fixing gasket 11, and an accompanying gasket, wherein the accompanying gasket comprises a double-strand gasket 6, a multi-strand gasket 8, and a polygonal gasket with holes.

[0029] The tail end of the suture needle 1 is provided with a threading hole 4, and one end of the fishbone wire 2 is inserted into the threading hole 4 and fixed inside the suture needle 1;

[0030] The fishbone wire 2 has a first exposed section of about 2 cm at the connection with the suture needle 1, a barb area 5 is provided at the upper middle part of the fishbone wire 2, a fishbone wire gasket 3 is provided at the tail end of the fishbone wire 2, and a second exposed section of about 3 cm is provided between the fishbone wire gasket 3 and the barb area 5;

[0031] The gasket 3 of the herringbone wire is a rounded square with a length and width of about 1 cm*1 cm. The external fixing gasket 11 is sleeved on the surface of the herringbone wire 2 and located in the barb area 5. The external fixing gasket 11 moves unidirectionally along the barb area 5.

[0032] During the operation, the doctor can pass the suture needle 1 of the herringbone wire 2 through the tissue that needs to be lifted, and then use the barb structure of the barb area 5 to pull the herringbone wire gasket 3 on the herringbone wire 2 to lift and pull the tissue. This design is not only easy to operate, but also can effectively expose the surgical field of view, thereby improving the efficiency and safety of the operation.

[0033] The external fixing gasket 11 is a rounded square, and has a first hole 7 at the center of the external fixing gasket 11. The diameter of the first hole 7 is 2 mm, and the shape of the first hole 7 is circular.

[0034] The external fixing pad 11 has a first hole 7 with a hole diameter of about 2 mm in the middle, and the first hole 7 is used for fixing within the range of the barb area 5. During the operation, the doctor can pass the herringbone wire 2 through the part that needs to be lifted, and add an external fixing pad 11 to the part. When lifting from the direction of the pad 3 provided by the herringbone wire, the external fixing pad 11 will be fixed due to the effect of the barbs in the barb area 5, which can not only protect the surface of the surgical part from damage, but also improve the stability and effect of lifting.

[0035] In this embodiment, if Figure 5 As shown, the suture needle 1 is normally in a straight needle state. According to different surgical requirements, surgical forceps can be used to change the suture needle 1 into a curved needle state. The suture needle 1 in the curved needle state can be equipped with an accompanying gasket to achieve a variety of combinations and improve surgical flexibility.

[0036] In this embodiment, the shape of the barb area 5 on the fishbone wire 2 is a fishbone shape. The angle between the barb area 5 of the fishbone wire 2 and the first exposed section is 100°. The length of the barb is about 1.5 mm, and the direction is consistent with the forward direction of the suture needle 1, which not only ensures the fixation effect but also reduces the possibility of tissue damage.

[0037] The barbed area 5 has a certain elasticity. When the in vitro fixing gasket 11 moves, the pointed end of the barbed area 5 is pressed, and the pointed end can move inward, so that the in vitro fixing gasket 11 can pass through the corresponding barbed area 5 to realize the unidirectional movement of the in vitro fixing gasket 11. The fishbone wire 2, the fishbone wire gasket 3, the barbed area 5, the double-strand gasket 6, the multi-strand gasket 8, and the in vitro fixing gasket 11 are all made of the same material.

[0038] In this embodiment, if Figure 3 and Figure 4As shown, a double-strand gasket 6 or a multi-strand gasket 8 can be provided in the portion between the gasket 3 provided on the fishbone wire and the barb area 5. The double-strand gasket 6 and the multi-strand gasket 8 respectively have a second hole 9 and a third hole 10. The second hole 9 and the third hole 10 are the same size as the first hole 7. When the fishbone wire 2 is used in combination with the double-strand gasket 6 or the multi-strand gasket 8, a larger fixing area can be provided, which is suitable for lifting in multiple directions and over a larger range.

[0039] Example 2: Please refer to Figures 5 to 8 , the utility model provides another technical solution:

[0040] A medical fishbone wire for lifting and pulling, comprising a suture needle 1, a fishbone wire 2, an external fixing gasket 11, and an attached gasket. The fishbone wire 2 can be bent, and the two ends of the fishbone wire 2 are respectively provided with a suture needle 1. The fishbone wire 2 is provided with two sections of aligned barb areas 5, and the third exposed section on the fishbone wire 2 passes through the attached gasket. The external fixing gasket 11 is placed within the range of the two sections of the barb areas 5 on the fishbone wire 2 and moves unidirectionally within the range of the barb areas 5. The suture needle 1 has plasticity and is a straight needle under normal conditions. The suture needle 1 can be bent when necessary to give the suture needle 1 an arc.

[0041] Different from the first embodiment, the two ends of the fishbone wire 2 of the present embodiment are pierced with a suture needle 1, so that the tissue can be lifted and pulled from both ends at the same time. At the same time, the fishbone wire 2 is provided with two sections of aligned barb areas 5, which also play the role of fixing and pulling; during the operation, the doctor can pass the two suture needles 1 of the fishbone wire 2 through the tissues that need to be lifted, and then lift and pull the tissue by pulling the attached gasket, which can be replaced with a double-strand gasket 6 or a multi-strand gasket 8 or a polygonal gasket with holes according to the needs.

[0042] By combining a straight fishbone wire 2 or a U-shaped fishbone wire 2 with an accompanying gasket, and combining fishbone wires of different lengths and angles according to actual requirements such as the lifting range and lifting direction, it has the advantages of shortening the surgical lifting time, improving the flexibility of surgical lifting, reducing manpower waste, and alleviating patient injuries.

[0043] The remaining parts not described in this utility model are existing or known technologies.

[0044] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
