technical field

The invention relates to the technical field of laparoscopic surgery application, in particular to an anti-aspiration insufflator for laparoscopic surgery.

Background technique

With the development of modern medicine, minimally invasive surgery has become the development direction of today's surgery. Minimally invasive surgery has less trauma, faster recovery and less pain, and has become the common goal and direction of modern medicine. Laparoscopic techniques are gradually replacing traditional surgery in some aspects. Aspirator for laparoscopic surgery is a commonly used surgical instrument for minimally invasive operations. Laparoscopic aspirator can easily absorb smoke, blood and fluid in the surgical area during minimally invasive surgery, keeping the surgical area clear and identifiable. . However, the surgical suction devices currently used in laparoscopy are all suction head ends with large apertures. While sucking smoke, blood, and fluid, if the operator is not skilled in using the suction, or does not operate properly, It is easy to suck the visceral tissue or omentum tissue in the abdominal cavity, resulting in blockage of the suction head, unable to suck up the effusion and blood, and at the same time causing bleeding of the laparoscopic visceral tissue, or sucking the laparoscopic tissue, resulting in tissue damage. To increase the secondary injury, it is necessary to further deal with the secondary injury, increase the difficulty of the operation, and bring some trouble to the doctor and the patient.

When you need to use the flushing function, you only need to press the operating room. The flushing and suction functions can be completed.

The advantages of the present invention are as follows: At present, in clinical practice, the laparoscopic aspirator surgical instruments used in surgery are all suckers with thick punching holes and large suction holes without protective devices. When the surgical operator uses the suction device , because the suction tip end of the suction device is thicker and larger, under the larger suction effect, the omentum, blood vessels, lymphatic vessels, and other soft tissues and organs in the surgical area are often caused by the larger suction effect. Under the action, it enters the suction hole of the suction device, resulting in tissue damage, bleeding, and even more serious problems. This side injury requires the surgeon to reprocess, repair, coagulate, etc., which significantly increases the operation time and increases the difficulty of the operation. At the same time, it brings unnecessary damage to the surgical patient. This surgical instrument can obviously avoid the occurrence of the above-mentioned situations. Using this instrument, in the process of suctioning smoke, blood, and fluid in the surgical area under laparoscopy, because the punching head 9 of the instrument has many punching and suction holes 12 , instead of a large punching and suction hole, and the outer layer of the punching and suction hole 12 is covered with a cloth bag 13, which can easily absorb smoke, blood and fluid according to the needs of the surgical area. The punching and suction hole 12 is isolated from the visceral tissues in the abdominal cavity, which effectively absorbs blood, fluid and smoke without sucking any omentum and visceral tissues in the abdominal cavity, which can effectively prevent secondary injuries. At the same time, if the amount of surgical bleeding is large, or blood clots appear, or other foreign bodies need to be sucked out by a larger diameter suction device, the suction head 9 of the device can be rotated to remove, The suction tube 2 of the flushing tip 9 interface carefully removes blood clots, or other tissues and foreign objects in the surgical area, so as to make the surgical area clear and ensure the safety of the surgical area. At the same time, this instrument can complete the flushing operation, and all It is completed by pressing the control suction method, which is easy to use, and the suction port 6 can be easily connected to the suction equipment in the operating room. After clinical use, this surgical instrument is easy to operate, fast and flexible, effectively saving operation time and improving operation safety.

The specific use and operation method of the present invention is as follows: when performing laparoscopic operation, when encountering tissue bleeding in the operation area, smoke formation, or fluid accumulation in the operation area, or there is fluid accumulation in the patient's pelvis, it needs to be removed by suction The three parts of the device can be combined together, and the combination is convenient. The method is as follows: firstly, one interface of the suction port 6 of the device is connected to the suction strap of the suction device in the operating room, and the other part of the device is connected. The flushing interface 6 is connected with the flushing leather strip of the flushing device, and the suction and flushing operations are performed by the suction generated by the suction device in the operating room and the flushing device. Switch (the flushing port 6 is connected to the flushing equipment, that is, the filling port; the flushing port 6 is connected to the suction device, even the suction port), and then put the rubber ring 14 of the cloth bag 13 on the flushing head 9, so that the rubber ring 14 is stuck At the slot 10, at this time, rotate the screw 11 on the punching head 9 as on the screw fixing end 1. Since the diameter of the punching head 9 is the same as that of the suction cylinder 2, when the screw 11 is tightened, the cloth bag 13 can be firmly The suction head 9 is firmly fixed on the head end of the suction cylinder 2. At this time, the instrument is put into the patient's body to be suctioned. Due to the function of the cloth bag 13, the suction head 9 is sucked. During the process of accumulation of blood, fluid and smoke, the omentum, tissues and organs in the abdominal cavity will not be inhaled, and no side damage will be caused. Even if the invisible pelvic area is inhaled, it can be safely operated. When performing the suction operation, it is only necessary to press the pressing handle 4 on the pipe connecting the suction port 6 to the suction equipment in the operating room, the spring 3 is compressed, the pull rod 8 moves inward, and the rubber pad 5 is opened to complete the suction operation. During the flushing operation, press the pressing handle 4 on the other flushing port 6 connected to the flushing device, the spring 3 under the pressing handle 4 is compressed, the pull rod 8 moves inward, and the rubber pad 5 that seals the flushing is opened, and it is completed. flushing operation. If a blood clot is encountered, the flushing head 9 can be rotated and removed to perform a larger blood clot suction operation. After the flushing head 9 is in the suction cylinder 2, it becomes a flushing device with a larger suction hole. , can perform intra-abdominal blood clots, and aspiration of larger necrotic tissue. After clinical use, the anti-aspiration inspirator for laparoscopic surgery can effectively and safely perform rinsing and suction operations on the operating area, significantly reduce the difficulty of the operation, improve the safety of the operation, and reduce the operation time, and is worthy of clinical promotion.

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made in these embodiments without departing from the principle and spirit of the invention , alternatives and modifications, the scope of the present invention is defined by the appended claims and their equivalents.
