Description

Technical Field

[0001] This utility model relates to a surgical implant retractor, and more particularly to a laparoscopic liver retractor. Background Technology

[0002] In traditional laparoscopic surgery, when the liver needs to be retracted to fully expose the surgical field, existing techniques employ the following two methods:

[0003] 1) Suture traction: Multiple thick threads are sewn onto the surface of the liver, and the sutures are led out of the body to suspend the liver and thus retract it. This suture traction method will inevitably cause damage to the liver, such as bleeding and tearing.

[0004] 2) Retraction with a fan-shaped retractor: A fan-shaped retractor is inserted into the abdominal cavity through a trocar to retract the liver and expose the surgical field. This fan-shaped retraction method requires an additional surgical channel (trocar) for the fan-shaped retractor, and a surgeon must hold the fan-shaped retractor throughout the procedure to maintain retraction on the liver.

[0005] As can be seen from the above, all existing technical solutions have shortcomings. Therefore, it is necessary to improve the existing laparoscopic liver retractor. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a laparoscopic liver retractor that can be directly inserted into the abdominal cavity through the skin without the need for an additional surgical channel, without damaging the liver, and without requiring the surgeon to hold and fix it throughout the procedure.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is to provide a laparoscopic liver retractor, including a hook leaf and a bedside fixation rod. The hook leaf includes a first straight rod part and a second straight rod part connected at 90 degrees vertically. The other end of the second straight rod part is a U-shaped rod. The other end of the first straight rod part is connected to one end of a crossbar through a hook leaf connector. The other end of the crossbar is connected to the bedside fixation rod through a crossbar connector. The bedside fixation rod is fixed in the base.

[0008] Furthermore, the open end of the U-shaped rod is bent outward to form a protrusion.

[0009] Furthermore, the hook-leaf connector includes a first through slot and a first rotating handle. One end of the crossbar is provided with a second through slot, and the other end of the first straight rod passes through the first through slot and the second through slot. The first straight rod can rotate around the crossbar and be locked by the first rotating handle.

[0010] Furthermore, the crossbar connector includes a vertically arranged third through slot and a fourth through slot, one end of the crossbar is snapped into the third through slot, and one end of the bedside fixing rod is snapped into the fourth through slot; the crossbar connector is provided with a second rotating handle, and the crossbar can rotate around the bedside fixing rod and be locked by the second rotating handle.

[0011] Furthermore, the base has a clamping part and a groove, the clamping part is used to clamp the edge of the operating table, and the other end of the edge fixing rod extends into the groove. Both the clamping part and the groove are fixed by locking screws (63).

[0012] Compared with the prior art, the present invention has the following advantages: The laparoscopic liver retractor provided by the present invention can be directly inserted into the abdominal cavity through the skin without the need for an additional surgical channel (puncture device). The liver is retracted by its U-shaped segment without damage to the liver. At the same time, it is fixed by the bedside bar, and the surgeon does not need to hold it for fixation throughout the process. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Figure 1 This is a schematic diagram of the laparoscopic liver retractor structure of this utility model; Figure 2 This is a schematic diagram of the hook structure of the liver retractor under laparoscopy according to this utility model.

[0023] Please see Figure 1 and Figure 2 The laparoscopic liver retractor provided by this utility model includes a hook leaf 1 and a bedside fixation rod 5. The hook leaf 1 includes a first straight rod portion 11 and a second straight rod portion 12 connected at 90 degrees vertically. The other end of the second straight rod portion 12 is a U-shaped rod 13. The other end of the first straight rod portion 11 is connected to one end of a crossbar 3 through a hook leaf connector 2. The other end of the crossbar 3 is connected to the bedside fixation rod 5 through a crossbar connector 4. The bedside fixation rod 5 is fixed in a base 6.

[0024] The laparoscopic liver retractor provided by this invention can be directly inserted into the abdominal cavity through the skin. Its U-shaped segment can fully lift and retract the liver without damaging it, thereby exposing the surgical field and ensuring traction throughout the entire surgical procedure. Preferably, the open end of the U-shaped rod 13 is bent outward to form a protrusion 14, which facilitates easier insertion into the abdominal cavity through the skin. Four different sizes of the hook blade 1 are available.

[0025] Please continue reading Figure 3 and Figure 4 The laparoscopic liver retractor provided by this utility model includes a hook connector 2 comprising a first through groove 21 and a first rotating handle 22. One end of the crossbar 3 is provided with a second through groove 31. The other end of the first straight rod portion 11 passes through the first through groove 21 and the second through groove 31. The first straight rod portion 11 can rotate around the crossbar 3 and be locked by the first rotating handle 22.

[0026] Please continue reading Figure 5 The laparoscopic liver retractor provided by this utility model includes a crossbar connector 4 with a vertically arranged third through groove 41 and a fourth through groove 42. The other end of the crossbar 3 is engaged in the third through groove 41, and one end of the bedside fixing rod 5 is engaged in the fourth through groove 42. The crossbar connector 4 is provided with a second rotating handle 43, and the crossbar 3 can rotate around the bedside fixing rod 5 and be locked by the second rotating handle 43.

[0027] Please continue reading Figure 6The laparoscopic liver retractor provided by this utility model has a clamping part 61 and a groove 62 formed on the base 6. The clamping part 61 is used to clamp the edge of the operating table, and the other end of the edge fixing rod 5 extends into the groove 62. The clamping part 61 and the groove 62 are both fixed by locking screws 63.

[0028] The laparoscopic liver retractor provided by this invention includes a U-shaped rod and a rod portion perpendicular to it at a 90-degree angle. This design allows the retractor, despite its three-dimensional structure, to be directly inserted into the abdominal cavity through the skin with a simple rotation. The laparoscopic liver retractor provided by this invention avoids liver damage caused by traditional liver retraction methods, reduces patient suffering (reducing the need for an additional few access points), and reduces the workload of the surgeon (eliminating the need for constant hand-held manipulation).

[0029] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
