Description

Non-pneumoperitoneum suspension device

Technical Field

The utility model relates to a pneumoperitoneum auxiliary device in laparoscopic surgery, in particular to a non-pneumoperitoneum suspension device for temporarily replacing pneumoperitoneum through machinery.

Background

At present, the known laparoscopic surgery generally realizes pneumoperitoneum by pumping carbon dioxide into the abdomen of a human body, the abdomen of a patient is in a bulged fornix shape, and the abdominal wall and visceral tissues have a certain separation space, so that the visual field of an operator is facilitated and the operation is performed by using instruments. The pneumoperitoneum mode is inflated by a pneumoperitoneum machine, so that a wider operation space is easily generated, the operation difficulty is relatively low, the pneumoperitoneum is easy to master and widely used, however, the pneumoperitoneum mode is also easy to generate a plurality of complications, such as too long pneumoperitoneum time, high-concentration carbon dioxide which is easy to cause hypercapnia, excessive helium which is easy to cause embolism and the like, which cause great operation risks, and are not favorable for performing laparoscopic surgery. Secondly, the pneumoperitoneum scheme adopts high-speed airflow to enter the abdominal cavity, so that tumor fragments are easily blown away in the operation process, and the tumor diffusion is caused, and the pneumoperitoneum scheme does not conform to the tumor-free principle of tumor operation (the recurrence rate of cervical cancer patients in pneumoperitoneum endoscopic surgery which is accepted medically at present is very high, and the cervical cancer operation is promoted in an open mode). Thirdly, the pneumoperitoneum mode is a relatively high-pressure space, but blood and smoke are often sucked through negative pressure during surgery, and the negative pressure easily causes the pneumoperitoneum to be shriveled, so that the visual field and the space of the surgery are damaged, and the surgery is not facilitated.

Because of the inherent disadvantages of the pneumoperitoneum approach, many non-pneumoperitoneum devices have been invented by search, and as the name suggests, the non-pneumoperitoneum approach is not through the way of blowing air, but through the principle of pure mechanical mechanics, such as pulling or supporting the abdominal wall of the patient through a mechanical device, thereby forming a pneumoperitoneum-like surgical abdominal space. The non-pneumoperitoneum devices basically solve some disadvantages of pneumoperitoneum, such as complications caused by gas, diffusion of tumor caused by blowing away tumor cells during inflation, difficulty in smoking and blood sucking during surgery, and the like, but the non-pneumoperitoneum devices completely eliminate pneumoperitoneum devices, namely, devices are all lifted or supported mechanically, when surgery begins, an operator needs to plug the devices between the abdominal wall and visceral tissues of the abdomen, and the plugging action has great risk because the abdominal wall and the viscera of a patient have insufficient space, and has great risk of damaging the viscera. Secondly, these devices for lifting or supporting generally adopt an upward suspension or support mode, the abdominal wall generally forms a trapezoidal state under the mechanical traction (in general pneumoperitoneum mode, the abdominal wall is in a vault shape instead of a ladder shape), the exposure to the opposite side direction is not sufficient, and again, these pure mechanical devices are basically realized by metal parts, and these metal parts with certain thickness generally need to penetrate through the abdominal wall of the patient, the abdominal wall of the patient will increase several holes, the injury is large, and the healing is difficult.

Therefore, the laparoscopic technique has inherent disadvantages in the pneumoperitoneum approach, and although some doctors have explored and invented some non-pneumoperitoneum devices, the non-pneumoperitoneum devices have not been widely used due to high operation difficulty, high risk and poor surgical field. Both the pneumoperitoneum mode and the non-pneumoperitoneum mode have their own disadvantages, which bring difficulty to the development of the laparoscopic technique.

Disclosure of Invention

In order to overcome the defects of the existing pneumoperitoneum mode and the non-pneumoperitoneum mode, the utility model provides a pneumoperitoneum laparoscope auxiliary device which adopts the mechanical principle, takes the pneumoperitoneum mode as the basis in the operation, utilizes the mechanical principle and follows the minimally invasive principle to form the operation space with the same vault shape of the pneumoperitoneum.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model discloses a mainly include external hanging device and internal suspension pole, external hanging device includes that one is located the support that suspends in midair directly over the patient's belly and is located two side position suspension support of patient both sides, and these three supports are all fixed in on the guide rail of operation table both sides through fixing device. Three intracavity central suspension rods are arranged, the three central suspension rods form a centrosymmetric structure in the abdominal cavity, and six included angles are equal to 60 degrees. The thin lines are tied in the middle of the X-shaped structure, penetrate through the abdominal wall, and suspend the three suspenders in the X-shaped structure on the suspension bracket right above the abdomen, and two intracavity suspenders are arranged on two sides of the abdominal cavity respectively and are suspended on the suspension brackets on two sides through the thin lines respectively.

During operation, an operator firstly uses the pneumoperitoneum machine to inflate, after the abdomen of a patient forms a fornix-shaped pneumoperitoneum, five suspenders are sequentially put into the inner side of the abdominal wall of the patient through the poking card, wherein the three middle suspenders form a 'x' shaped structure, and a thin line tied in the middle of the 'x' shaped structure penetrates out of the abdominal wall 1 cm above an umbilical eye and is tied on the middle suspenders. The two hanging rods on the two sides are respectively positioned at the position of the front axillary line of the patient, and the fine lines on the hanging rods respectively penetrate out from the two sides of the abdominal wall and are tied and buckled on the hanging brackets on the two sides. Finally, three suspenders in the star-shaped structure in the middle of the abdominal wall are suspended upwards, and two suspenders in the front axillary line are suspended towards two sides. At this time, the pneumoperitoneum machine was stopped, and the abdominal wall was kept in the same vault state as in the pneumoperitoneum state by the mechanical suspension action of the five suspension rods.

The utility model has the beneficial effects that firstly, the pneumoperitoneum device is built in the pneumoperitoneum space when the operation is started and ended on the basis of the pneumoperitoneum mode, so that the risk that internal organs are easily damaged when a plurality of non-pneumoperitoneum devices are deployed is fundamentally avoided. Secondly, in the operation process, the inflation of the pneumoperitoneum machine is stopped, the operation is carried out by utilizing the mechanical lifting space, the pneumoperitoneum time is greatly shortened, the complications caused by long-time injection of CO2 and helium are avoided for a patient, the use of the pneumoperitoneum machine is reduced, the risk of blowing away tumor cells is reduced, the tumor-free principle is practiced, and meanwhile, the smoking and blood sucking are facilitated. Thirdly, the device changes the mode that a plurality of non-pneumoperitoneum devices are only supported or suspended upwards, adopts the mode of combining the upward suspension and the suspension towards two sides, and is built on the basis of pneumoperitoneum, thereby realizing the intracavity space which is almost the same as the pneumoperitoneum, having enough clear exposure to the side direction, and being very beneficial to the visual field of an operator and the operation. Fourthly, as the suspension part of the device adopts a mode of combining the hard rod and the wire, when in suspension, the hard rod enters the abdominal wall through the poking card of the endoscope, and the fine wire passes out of the abdominal wall through the tiny needle eye, thereby avoiding the wound that a plurality of non-pneumoperitoneum mechanical devices increase a plurality of holes on the abdominal wall of a patient at present and being in accordance with the principle of micro-invasion. In a word, the device is favorable for an operator to use the endoscopic instrument for surgery, and is favorable for the safety of the surgery and the healing of a patient.
