Description

Technical Field

[0001] The utility model relates to a single-hole laparoscopic abdominal wall fixing device, in particular to an inflation-free single-hole laparoscopic abdominal wall fixing device, belonging to the technical field of medical equipment. Background Art

[0002] In the non-inflatable single-port laparoscopic surgery, only one incision is made at the human navel, and then the incision is supported and fixed by an abdominal wall fixation device, and the operator's surgical instruments can enter the human abdominal cavity through the incision for operation. Most of the existing abdominal wall fixation devices are umbrella-shaped, such as Chinese patent No. 201310573823.9, and the patent name is "Umbrella-type abdominal wall suspension device for laparoscopic surgery", which includes a suspension umbrella, a mechanical arm and a fixed rod. The suspension umbrella is suspended on the mechanical arm, and the mechanical arm is installed on the fixed rod. The suspension umbrella is composed of a sleeve, a needle core, a dead point ring and a hanging chain. The sleeve is composed of spokes and a push-pull tube. The push-pull tube slides downward, and the spokes slide and fold toward the center through the proximal joint, the distal joint and the middle joint to form an umbrella shape. The disadvantages of this structure are: 1. During surgery, surgical instruments must be inserted into the abdominal cavity between the spokes of the suspension umbrella. The dense spokes can easily block the surgical instruments, thus affecting the operation of the operation; 2. The device can only support the incision of the abdominal wall and pull the abdominal wall upward, but cannot change the angle of the incision plane, that is, it cannot change the inclination angle of the incision. In this way, it is difficult for surgical instruments to enter the deeper parts of the abdominal wall, which increases the difficulty of the operation; 3. The device needs to be inserted vertically into the abdominal cavity to a certain depth in the interference state before the spokes can be opened into an umbrella shape. The space in the abdominal cavity is limited. Blindly inserting the device and further opening it to the surroundings without looking directly into the abdominal cavity may cause damage to the intestinal tract. Therefore, the applicant has applied for Chinese utility model patent 201721674921.1, and the patent name is "Single-hole abdominal wall fixation device for gas-free laparoscopic surgery", but the structure has the following disadvantages: 1. When using electric knife and ultrasonic knife for surgery, smoke and water mist will be generated in the abdominal cavity, and a straw needs to be inserted from the operation hole to absorb the smoke and water mist to make the surgical field clear, but the straw can easily interfere with the electric knife, ultrasonic knife, etc., affecting the surgery; 2. A handle plate is made on the connecting plate, but the handle plate needs to be lifted by hand by medical staff, which is troublesome and laborious to operate, and the lifting stability is poor; 3. When the lens is inserted into the abdominal cavity, there is no structure to fix the lens, and the medical staff needs to hold it with their hands all the time, which is very laborious, and the stability of the lens is poor.

When one side of the vertical plate 11 is pulled up, the vertical plate 11 drives the connecting plate 4 and the side hook 5 of the corresponding side upward, and the connecting plate 4 and the side hook 5 drive the fixing plate 1 and the operation hole 3 to tilt toward the side, so that the surgical field in the abdominal cavity of the corresponding side can be fully exposed, thereby facilitating the doctor to observe and operate.

[0017] Furthermore, a fixing column 13 is formed on the fixing plate 1. A collar can be provided on one side of the lens (the specific structure of the lens is a prior art), and the lens can be sleeved on the fixing column 13 through a sleeve, so that the lens can remain stable.

[0018] Furthermore, the adjustment device includes studs 14 formed on the upper left and right sides of the fixing plate 1 at the operation hole 3, and an adjustment hole 15 is opened in the connecting plate 4. The stud 14 passes through the adjustment hole 15, and an adjustment nut 16 and a nut 17 are arranged on the stud 14. The adjustment nut 16 and the nut 17 are threadedly matched with the stud 14, and the adjustment nut 16 contacts the bottom of the connecting plate 4, and the nut 17 contacts the top of the connecting plate 4. The height of the connecting plate 4 and the side retractor 5 can be adjusted by rotating the adjustment nut 16, which plays a role in adjusting the distance between the side retractor 5 and the fixing plate 1, and can adapt to patients with different abdominal wall thicknesses. The nut 17 is used to press and fix the connecting plate 4 after it is adjusted into place, so as to ensure that the connecting plate 4 and the side retractor 5 can be fixed reliably.

[0019] Furthermore, the adjustment hole 15 is a long hole, and its length L is 20-40 mm. The adjustment hole 15 is set as a long hole.

When operating, an incision is first made at the navel of a human body, and then a flat tube 8 bent downwardly on the inner wall of an operation hole 3 of a fixing plate 1 is extended from the incision, and the abdominal wall on the rear side of the incision is hooked by the flat tube 8 bent downwardly, and then an adjusting nut 16 is first installed on the stud 14 of the fixing plate 1, and two connecting plates 4 are taken, and side retractors 5 under the connecting plates pass through the operation hole 3 of the fixing plate 1 and the incision of the abdomen, one of the side retractors 5 hooks the abdominal wall on the left side, and the other side retractor 5 hooks the abdominal wall on the right side, and the left, right and rear abdominal walls of the incision are supported by the left and right side retractors 5 and the flat tube 8, and then the connecting plate 4 is clamped on the stud 14 through the adjusting hole 15, and the ingot nut 17 is screwed in to tighten the connecting plate 4, and finally the handle 2 and the vertical plates 11 on the left and right connecting plates 4 are fixed to the suspension system (the specific structures of the suspension system and the suspension roller are existing technologies) through the suspension roller. The present invention is an inflation-free single-port laparoscopic abdominal wall fixation device, which is improved according to the existing patent of the applicant. First, the head of the suction tube 6 is made into a flat tube 8 that bends downward in an arc shape, and one side of the flat tube 8 is directly fixed to the inner wall of the operation hole 3 of the fixing plate 1 by welding. The flat tube 8 can be used as a suction tube to absorb the smoke and water mist generated in the abdominal cavity during surgery, and can also be used as a rear hook structure to tighten and support the rear abdominal wall of the abdominal incision of the human body.
