Description

Technical Field

[0001] The utility model relates to the field of operating forceps, in particular to a laparoscopic operating forceps used for measurement. Background Art

[0002] Many laparoscopic surgeries require organ length measurement, and some, such as the length of the small intestine, require continuous measurement. Unlike open surgery, the difficulty and accuracy of measurement in laparoscopic surgery are often lower. Here, we take the SADI-S procedure in bariatric surgery as an example.

[0003] In SADI-S surgery, it is necessary to count 200-400cm of intestine upward from the ileocecal region and perform a duodenoileal anastomosis. In laparoscopic surgery, due to the limitations of field of view, space and instruments, the surgeon can currently only measure the length of the intestine under the microscope using two grasping forceps and a 20cm ruler. The specific method is to first use a grasping forceps to fix the distal intestine, use a 20cm ruler to locate the proximal end, use another grasping forceps to fix the positioning point at 20cm, release the distal grasping forceps and fix the positioning point, use the 20cm ruler to locate the proximal end again, and continue the above cycle. This method has a large measurement error, the scale is difficult to be parallel to the intestine, and this method is complicated to operate, time-consuming and labor-intensive, and prolongs the operation time. Therefore, there is a need for an instrument that can both fix the intestine under laparoscopy and perform length detection at the same time, thereby greatly simplifying the measurement process and shortening the operation time.

[0004] Among the patents currently applied for, CN 117442301 A proposes a more reasonable laparoscopic measurement device. It combines a measuring tape with laparoscopic operating forceps, places the scale line inside the operating rod, and uses the two operating forceps to pull the measuring line out from the front end of the operating rod. The intestine is clamped by the grasping forceps to achieve the measurement effect. However, this solution includes an automatic wire retraction device. If a long section of small intestine is to be measured, it needs to be pulled out and automatically retracted multiple times. The space in the abdominal cavity is small, and there is a risk of cutting the intestine. In addition, the fixed coil is easy to fall out, which also increases the risk of cutting.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The embodiment of the utility model discloses a laparoscopic operating forceps for measurement, which includes two mutually cooperating operating forceps (forceps A and forceps B), both of which are provided with a clamp 6 and a holding rod 5, wherein forceps A includes a measuring line device, and forceps B includes a coil locking device.

[0024] A clamp has a clamp 6 at one end and a gripping rod 5 at the other. A measuring line device is located at the end where gripping rod 5 is located. The measuring line device includes a reel 4 around which a measuring line 1 can be wound. The measuring line 1 can be drawn from the reel 4 to the end where clamp 6 is located. The measuring line device also features a fixing block 3 and a slide rail 2 that cooperate to lock the measuring line 1. Furthermore, a knob 9 is connected to the reel 4, which can be turned to wind the line.

[0025] The b clamp is also provided with a clamp 6 at one end and a holding rod 5 at the other end, wherein the end where the clamp 6 is located is provided with a side rod 7 that can close the head coil of the measuring line 1, and the side rod 7 can be rotated through a hinge structure. The end where the holding rod 5 is located is also provided with a holding rod 2 8 that can control the opening and closing state of the side rod 7.

[0026] Specifically, the structures of each part in this utility model are described as follows:

[0027] 1. A measuring line 1 having all centimeter-level scales from 0 to 30 cm, the end of which is fixed and wound on a reel 4;

[0028] 2. Push the slide rail 2 forward until it fits into the slot of the fixed block 3, locking the measuring line 1.

[0029] 3. Fixed block 3, with a slot in the middle, used to lock the slide rail 2 and the measuring line 1;

[0030] 4. The reel 4 is fixed to the end of the measuring line 1 and can be used to roll up the measuring line 1. It is connected to the external knob 9 so that the line can be wound by rotating it.

[0031] 5. The gripping rod 5 has a hinge structure with the clamp 6 and is used for basic clamping operations;

[0032] 6. Clamp 6, having a hinge structure with the gripping rod 5;

[0033] 7. The side rod 7 and the second handle rod 8 have a hinge structure, and the side rod 7 can be opened and closed by operating the second handle rod 8;

[0034] 8. The second gripping rod 8 is hinged with the side rod 7;

[0035] 9. Knob 9 is connected in series with the reel 4, and the line can be wound by knob 9.

[0036] It should be noted that the core measuring line 1 is a nylon line with a diameter of approximately 1 mm and is black with a blue scale from 1 cm to 30 cm. The utility model is a pair of operating pliers, wherein pliers A includes a measuring line device and pliers B includes a coil locking device. After pliers A and B enter the abdominal cavity, pliers B opens the side rod 7 at the front end of the operating rod, inserts the coil of pliers A, and then closes the side rod 7 to form a closed device of pliers A + pliers B. Pull out the measuring line 1 through pliers A to the required length, push the slide rail 2 of the base of pliers A forward, and lock the length of the measuring line 1. Then pliers A grasps the small intestine, and pliers B straightens the measuring line 1 along the small intestine. After straightening, clamp the corresponding small intestine, then release pliers A, grasp the position of pliers B, release pliers B, and repeat the above operation. After completing the measurement, release the clamping device of pliers B to remove the coil. Rewind the measuring line 1 through the knob 9 of the base of pliers A.
