Description

Technical Field

[0001] The present invention relates to a channel device for multi-channel single-port laparoscopic surgery in the field of medical instruments, which is suitable for use with a multi-channel single-port laparoscope. It is an endoscope-matching surgical instrument used in laparoscopic surgery and minimally invasive surgery to expand the surgical field of view, protect the incision from damage and reduce incision infection. Background Art

[0002] With the development of laparoscopic equipment and technology, laparoscopic minimally invasive surgery has been widely used in abdominal surgery. Compared with traditional open abdominal surgery, laparoscopic minimally invasive surgery has outstanding advantages such as minimal invasiveness, safety, aesthetics, and less postoperative pain. It minimizes the impact of surgery on patients, has obvious advantages in reducing postoperative incision pain and abdominal wall paresthesia, and shortens the patient's postoperative recovery period.

[0003] Multi-channel single-port laparoscopes are often used in laparoscopic surgeries such as cholecystectomy, total gastrectomy, appendectomy, and intrahepatic bile duct cystadenoma resection. The multi-channel single-port laparoscope includes a multi-porous operating platform and an abdominal channel device connected to the multi-porous operating platform. During the actual operation, the abdominal channel device needs to be connected to the multi-porous operating platform, and the air tightness of the connection between the two needs to be ensured. The existing multi-channel single-port laparoscope has poor sealing performance when connected to the multi-porous operating platform. It is easy to fall off, leak, and be difficult to disassemble and assemble during use, affecting the progress of the operation. Therefore, it is necessary to propose a channel device for multi-channel single-port laparoscopic surgery. Summary of the invention

[0004] The purpose of the present invention is to provide a multi-channel single-port laparoscopic surgery channel device to address the above-mentioned deficiencies. The channel device has a simple structure, good channel device fixing effect, excellent sealing performance and easy operation.

[0005] The multi-channel single-port laparoscopic surgery channel device is realized by adopting the following technical solutions:

[0006] The channel device for multi-channel single-port laparoscopic surgery comprises a clamp fixing ring, a disassembly connection handle, a channel ring body and a channel insertion fixing ring. The upper part of the channel ring body is provided with a clamp fixing ring, the upper end of the clamp fixing ring is provided with a disassembly connection handle, and the lower part of the channel ring body is provided with a channel insertion fixing ring.

[0007] An installation guide arc is provided on the snap ring fixing ring, and a positioning buckle groove is provided under the snap ring fixing ring. The positioning buckle groove is connected through the sealing fixing ring and the installation guide arc. The positioning buckle groove and the sealing fixing ring form a step and are at a right angle. The inner diameter of the snap ring fixing ring is smaller than the outer diameter of the positioning installation groove of the sealing snap ring plate, so that the sealing buckle is installed in the positioning installation groove of the sealing snap ring plate to ensure that it will not slip.

[0008] There are at least two disassembly and connection handles, and the left disassembly and connection handle and the right disassembly and connection handle are horizontally and symmetrically arranged on both sides of the outside of the clamp fixing ring. Connecting arcs are arranged at both ends of the disassembly and connection handles. The disassembly and connection handles facilitate easier pressure relief and disassembly during surgical operations.

[0009] The channel ring body is provided with a channel for instruments to pass through, and a conical lower trumpet is provided under the channel ring body. The angle α of the conical lower trumpet with the channel ring body as the center is 20°≤α≤80°. By providing the channel ring body with a channel for instruments to pass through, the instrument can rotate at a larger angle under the minimum incision, which facilitates the surgical operation while minimizing the harm to the patient.

[0010] A ring body connecting handle is provided at the lower part of the channel ring body, and a relaxation groove arc is provided at the connection between the ring body connecting handle and the channel ring body. There is at least one ring body connecting handle, and the ring body connecting handle and the disassembly connecting handle are located on the same horizontal line in the vertical direction, which helps to better judge the position of the ring body connecting handle at the end of the operation, and it is more convenient to remove the incision after the channel is placed in the fixing ring, thereby reducing incision damage.

[0011] The channel inserting fixing ring is flush with the lower end of the ring body connecting handle. In order to improve the firmness and sealing performance of the channel device, the clamp fixing ring, the disassembly connection handle, the channel ring body and the channel inserting fixing ring are all made of silicone or rubber or silicone rubber material and are integrally injection molded.

[0012] As a preference, the detachable connection handle can be configured as a handle without a hole (e.g. Figure 4 ) or handle with holes (such as Figure 5 ), the hole on the perforated detachable connecting handle can be a round hole, an elliptical hole, a square hole or a triangular hole, so that the operator can have better adhesion and will not slip when the hand is stained with liquid during surgery.

[0013] As a preference, the channel ring body may be configured in a bell-mouth shape (e.g. Figure 4 ) or straight channel shape (such as Figure 6 ).

[0014] Preferably, the ring body connecting handle arranged at the lower part of the channel ring body can be a cylinder, a cone or a square column.

[0015] When the multi-channel single-port laparoscopic surgical channel device of the present invention is used, the channel is first inserted into the fixing ring and flattened into an elliptical shape with surgical forceps, and then inserted into the surgical incision. The channel is inserted into the surgical incision and the fixing ring is restored by its own elasticity, and the clamp fixing ring is fixedly installed in the positioning installation groove outside the sealing clamp plate, and then the sealing clamp plate connecting handle on the sealing clamp plate and the operating platform connecting handle on the multi-porous operating platform are installed in a displaced manner, and fixed and locked by a locking buckle. At this time, the bowl-shaped channel opening at the bottom of the multi-porous operating platform is closely connected with the upper channel opening of the channel ring body, and the channel ring body is close to the surgical incision wall. The surgical instrument passes through the incision channel in the middle of the channel ring body and conveniently enters the human body cavity for surgical operation.

[0016] The channel device for multi-channel single-port laparoscopic surgery of the present invention is reasonably designed and compact in structure. Since a clamp fixing ring, a disassembly connection handle, a channel ring body and a channel insertion fixing ring are provided, it can ensure that the multi-channel single-port laparoscope and the channel device for multi-channel single-port laparoscopic surgery have good firmness, excellent sealing performance and easy assembly and disassembly, which greatly expands the surgical operation angle and provides convenience for the doctor's surgical operation.
