Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical surgery, and in particular to a common bile duct exploration accessory used for medical surgery. Background Art
[0002] Surgery refers to the use of medical instruments by doctors to perform excisions and suturing on the patient's body. It is the main surgical treatment method, and its purpose is to treat or diagnose diseases, such as removing diseased tissues, repairing injuries, transplanting organs, and improving the body's function and morphology. Early surgeries were limited to simple manual methods of cutting, cutting, and suturing on the body surface, such as abscess drainage, tumor removal, and trauma suturing. Therefore, surgery is an operation that destroys the integrity of tissue (incision) or restores the integrity of damaged tissue (suturing). With the development of surgical technology, laparoscopic surgery has become the preferred surgical method. It creates an air cavity space, allowing surgeons to perform surgical operations through operating rods, so it requires better auxiliary tools for anatomical exposure operations.
[0003] In order to facilitate entry when a laparoscopic choledochoscope is inserted into the common bile duct for exploration, a larger common bile duct exploration opening is generally required, and an assistant is required to assist in entering the bile duct end. However, the clamping operation can easily damage the abdominal end of the choledochoscope, and the entry angle needs to be more precisely controlled, which is not conducive to operation. After entry, it is easily affected by the close-fitting posterior wall of the common bile duct. Therefore, an assistant is required to repeatedly help open the common bile duct exploration opening, which can also easily cause accidental damage to the bile duct wall tissue. Utility Model Content
[0004] The utility model provides a common bile duct exploration accessory for surgical biliary surgery, which solves the problems of being unfavorable for operation during surgery and easily damaging the abdominal cavity end of the choledochoscope and the bile duct wall during operation.
[0005] The technical solution of the utility model is as follows:
[0006] A common bile duct exploration accessory for surgical biliary surgery comprises a connecting piece, both sides of the top of the connecting piece are fixedly connected with auxiliary clamping suspension handles, and two groups of anti-slip protrusions are embedded on the outside of the connecting piece.
[0007] Preferably, the two auxiliary clamping suspension handles are symmetrically distributed, and the two groups of anti-slip protrusions are in a circular array.

[0022] The following will be combined with 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 of 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.
[0023] like Figure 1 to Figure 3 As shown, this embodiment proposes a common bile duct exploration accessory for surgical biliary surgery, including a connector 1, both sides of the top of the connector 1 are fixedly connected with auxiliary clamping suspension handles 2, and two groups of anti-slip protrusions 3 are embedded on the outside of the connector 1 to facilitate the anti-slip work of the overall structure.
[0024] In this embodiment, the two auxiliary clamping suspension handles 2 are symmetrically distributed, and the two groups of anti-skid protrusions 3 are both in a circumferential array, which can prevent the accessory from slipping when it is placed into the common bile duct through the anti-skid protrusions 3.
[0025] In this embodiment, the connecting member 1 is fixedly connected to a conical connecting tube 4 inside, and the conical connecting tube 4 is fixedly connected to a connecting outer plate 5 outside, so that the connecting member 1 can drive the conical connecting tube 4 and the connecting outer plate 5 to move.
[0026] In this embodiment, the overall connection shape of the connecting member 1, the conical connecting tube 4 and the connecting outer plate 5 is an “I” shape.
[0027] In this embodiment, an insertion guide flap 6 is fixedly connected to one side of the outer side of the connecting outer plate 5 . The insertion guide flap 6 is in a spirally raised shape, which can facilitate the screwing work of the insertion guide flap 6 .
[0028] In this embodiment, a direction guide flap 7 is fixedly connected to one side of the bottom of the connecting outer plate 5. The direction guide flap 7 is arranged in an arc shape, which can facilitate padding the tissue inside the common bile duct.
[0029] In this embodiment, a direction guide line is provided on one side of the top of the connector 1. The direction guide line is filled with blue color, which can facilitate the staff to identify the use direction of the structure.
[0030] During use, when it is necessary to perform surgery on the patient, the staff first needs to use a tool to lift the auxiliary clamping suspension handle 2. When the auxiliary clamping suspension handle 2 is lifted, it will synchronously drive the connecting piece 1 to move upward. During the movement, the connecting piece 1 will synchronously drive the conical connecting tube 4 to move. During the movement, the conical connecting tube 4 will synchronously drive the connecting outer plate 5 to move. During the movement, the connecting outer plate 5 will synchronously drive the direction guide flap 7 to move. During this process, the inserted guide flap 6 will move synchronously. Then the staff will pad the direction guide flap 7 into the patient's common bile duct and rotate the auxiliary clamping suspension handle 2 at the same time. The auxiliary clamping suspension handle 2 will synchronously drive the connecting piece 1 to rotate at this time. During the rotation of the connecting piece 1, the anti-slip protrusion 3 will synchronously rotate. At the same time, the conical The connecting tube 4 will drive the connecting outer plate 5 to rotate, and the connecting outer plate 5 will synchronously drive the insertion guide flap 6 to rotate during the rotation process. Since the insertion guide flap 6 is a short spiral, it will synchronously unscrew the cavity wall inside the common bile duct during the rotation process. At this time, the direction guide flap 7 can guide the direction and pad the front and rear walls. At the same time, the exploration port can remain open. The staff only needs to use the auxiliary clamping suspension handle 2 to help lift when necessary, reducing the direct and repeated lifting and expansion operations on the patient's bile duct wall and reducing tissue damage. The anti-skid protrusion 3 will ensure the anti-skid effect of the connector 1 during this process to prevent the connector 1 from entering the patient's body. During the operation, the auxiliary clamping suspension handle 2 needs to be kept perpendicular to the longitudinal diameter of the common bile duct. At the same time, the direction of the direction guide flap 7 needs to be kept correct.
[0031] During surgery, the direction-guiding flap 7 enables the biliary end of the choledochoscope to find its direction after entering the abdominal cavity. At the same time, after the auxiliary component is placed, the flap forms a certain space between the front and rear walls of the common bile duct at the entrance, and the lower opening of the auxiliary component is slightly larger than the upper opening, so that the lens has sufficient adjustment space; secondly, the flap blocks the reflux activity of small stones during the exploration process, reducing the re-entry of stones into the explored side during the reversal exploration;
[0032] This part is made of silicone, which is smooth when in contact with water and has low friction, which is conducive to the passage of the lens. Therefore, an anti-slip protrusion 3 is designed to facilitate overall clamping when inserted.
[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
