Description

Technical Field

[0001] The utility model relates to the field of surgical instruments, in particular to a multi-channel platform for laparoscopic surgery. 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] Laparoscopic surgeries include cholecystectomy, total gastrectomy, appendectomy, and intrahepatic bile duct cystadenoma resection. During the operation, the abdominal channel device needs to be connected to the multi-porous operating platform, and the airtightness of the connection must be ensured. Currently, when using the existing abdominal channel device with the multi-porous operating platform, the abdominal channel device is simply inserted into the multi-porous operating platform, or sealed with a rubber band, resulting in poor connection sealing performance. It is easy for the device to fall off or leak during use, affecting the progress of the operation. Therefore, it is necessary to propose a multi-channel platform for laparoscopic surgery. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a multi-channel platform for laparoscopic surgery, which has good sealing performance and is not easy to fall off.

[0005] The utility model is achieved through the following technical solutions:

[0006] A multi-channel platform for laparoscopic surgery, characterized by comprising a base, one side of which is provided with an incision protection cover, and the other side of which is provided with at least one channel tube and a connection valve for connecting to a pneumoperitoneum machine;

[0007] The base is provided with at least one first interface, and the at least one channel tube is provided in a one-to-one correspondence with the at least one first interface. The channel tube includes a connecting portion, which is provided in the first interface and abuts against a fourth inner wall forming the first interface. The outer wall of the connecting portion is provided with at least one groove. The base is elastic, and the side wall forming the first interface is at least partially received in the groove.

[0008] A sealing valve is provided in the channel tube. When a surgical instrument is not inserted into or leaves the channel tube, the sealing valve closes under its own elastic action, thereby sealing the channel tube.

[0009] Furthermore, the groove is an annular groove.

[0010] Furthermore, the sealing valve is made of elastic material and is provided with a straight-shaped opening. When the surgical instrument is not inserted into or leaves the channel tube, the sealing valve closes the opening under the action of its own elasticity.

[0011] Furthermore, reinforcing ribs are respectively provided on both sides of the opening, and the reinforcing ribs are integrally formed on the sealing valve.

[0012] Furthermore, the channel tube includes a second shell, the connecting portion is provided on the second shell, a second clamping ring is formed on the second shell, and the second clamping ring abuts against a second inner wall forming the first interface.

[0013] Furthermore, the channel tube further includes a first shell that is clamped with the second shell, a first protrusion is formed on the first shell, and the first protrusion abuts against the third inner wall of the second shell.

[0014] Furthermore, a third protrusion is formed on the second shell, a clamping groove is formed on the sealing valve, and the third protrusion is clamped in the clamping groove.

[0015] Furthermore, a protective sheet is provided above the sealing valve, and the center of the protective sheet is aligned with the opening to guide surgical instruments to prevent damage to the sealing valve.

[0016] Furthermore, a second protrusion is formed on the first shell, and one end of the protective sheet abuts against the sealing valve, and the other end abuts against the second protrusion.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] 1. By setting up a flexible incision protection cover, the surgical platform can be relatively freely moved relative to the surgical incision while ensuring pneumoperitoneum closure.

[0019] 2. By setting a sealing valve, the sealing valve will close under its own elasticity after the surgical instruments are withdrawn, ensuring the tightness of the pneumoperitoneum. The process can be completed by a single person.

[0020] 3. By providing a base made of elastic material and opening at least one groove at the connection part, since the base is elastic, the side wall of the first interface on the base is at least partially received in the groove after assembly, so that the connection between the channel tube and the base is airtight and not easy to fall off.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] like Figure 1 As shown, a multi-channel platform for laparoscopic surgery in one embodiment of the present invention includes a base 1, one side of the base 1 is provided with an incision protection cover 6, and the other side is provided with at least one channel tube 2 and a connecting valve 3 for connecting to a pneumoperitoneum machine.

[0031] like Figures 2 to 4 As shown, the base 1 is provided with at least one first interface 4, and at least one channel tube 2 is provided in a one-to-one correspondence with at least one first interface 4. In this embodiment, the base 1 is cylindrical and integrally formed with three first interfaces 4, and the three first interfaces 4 have at least two different specifications. Preferably, the base 1 and the first interfaces 4 are integrally injection molded and are both made of an elastomeric material.

[0032] At least two second interfaces 30 are also formed on the base 1, and the connecting valve 3 is clamped in the second interface 30. The connecting valve 3 is in a closed state under normal circumstances. When the pneumoperitoneum machine needs to be connected, one of them can be selected. When one of the connecting valves 3 is damaged, other connecting valves 3 can be selected for use.

[0033] An accommodating cavity 14 is further formed in the base 1 . A first clamping ring 11 is protruded from a first inner wall 10 of the accommodating cavity 14 , and the incision protection sleeve 6 is clamped on the first clamping ring 11 .

[0034] like Figure 5 As shown, the incision protection sleeve 6 includes a first support ring 60, a second support ring 61, and a protective film 62. The first support ring 60 is received in the accommodating cavity 14 and is clamped to the first clamping ring 11. One end of the protective film 62 is fixedly connected to the first support ring 60 by heat-melting, and the other end is fixedly connected to the second support ring 61 by heat-melting. Preferably, the first support ring 60 and the second support ring 61 are both made of an elastomeric material, and the protective film 62 is a thin film made of a medical polymer material.

[0035] like Figure 6 and Figure 7 As shown, the channel tube 2 includes a shell 20, a sealing valve 21 and a protective sheet 5. A portion of the shell 20 is installed in the corresponding first interface 4, the sealing valve 21 is installed in the shell 20, and the protective sheet 5 is arranged above the sealing valve 21 to guide surgical instruments to prevent damage to the sealing valve 21.

[0036] Specifically, such as Figure 3 As shown, the housing 20 includes a first shell 201 and a second shell 202 snap-fitted to the first shell 201 . A first protrusion 203 and a second protrusion 204 are formed on the first shell 201 . The first protrusion 203 abuts against the third inner wall 206 of the second shell 202 for fixing the first shell 201 and the second shell 202 .

[0037] The second housing 202 is provided with a connecting portion 208 and a second retaining ring 23. The connecting portion 208 is embedded in the corresponding first interface 4 and abuts against the fourth inner wall 209 forming the first interface 4. The outer wall of the connecting portion 208 is provided with at least one groove 13. The base 1 is elastic, and the side wall 40 forming the first interface 4 is at least partially received in the groove 13. Preferably, the groove 13 is an annular groove. The second retaining ring 23 abuts against the second inner wall 12 forming the first interface 4 to prevent the channel tube 2 from falling off during surgery.

[0038] A third protrusion 205 is also formed on the second shell 202, and a slot 207 is formed on the sealing valve 21. The third protrusion 205 is clamped in the slot 207. One end of the protective sheet 5 abuts against the sealing valve 21, and the other end abuts against the second protrusion 204. The center of the protective sheet 5 is aligned with the opening 210, which is used to guide surgical instruments to prevent damage to the sealing valve 21.

[0039] The sealing valve 21 is made of an elastic material and has a straight-line opening 210. When a surgical instrument is not inserted into or removed from the channel tube 2, the sealing valve 21 closes the opening 210 due to its own elasticity. Reinforcing ribs 211 are provided on either side of the opening 210. These ribs are integrally formed with the sealing valve 21 to prevent the opening 210 from flanging or becoming detached, improving the sealing effect.

[0040] During surgery, the second support ring 61 of the incision protection sleeve 6 is first pressed and placed into the surgical incision. After the second support ring 61 recovers due to its own elasticity, it stretches the protective film 62 and protects the surgical incision. The surgical instrument then selects the appropriate channel tube 2 to enter and exit the patient's abdominal cavity. When the surgery is complete, the surgical instrument is removed, and the sealing valve 21 closes due to its own elasticity.

[0041] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
