Description

Method for taking out in-vivo large-volume solid tumor through single hole

Technical Field

The invention relates to the technical field of pollution gas monitoring, in particular to a method for taking out a large-volume solid tumor in a body through a single hole.

Background

The rapid development of modern medical technology has gradually prolonged the average life of human beings, and the requirements of people on the treatment of diseases are not only satisfied with the curative effect, but also the requirements on the quality of life after treatment are higher and higher. Therefore, when selecting a surgical approach, both for the physician and the patient, in addition to considering the treatment of the disease itself, there is an increasing concern about the impact on quality of life, and there is a greater tendency to select a more minimally invasive approach, which also encourages surgeons to continually seek less traumatic, faster-recovery surgical approaches. In the gynecological field, laparoscopic surgery has become one of the main surgical approaches, and is a safe and reliable mainstream choice, especially in gynecological benign diseases. In recent years, with the continuous improvement of laparoscopic surgery technology and the gradual update of surgical instruments, the development of single-port laparoscopic surgery is rapidly advanced, compared with multi-port laparoscopic surgery, the single-port laparoscopic surgery has smaller trauma and more concealed and beautiful incision, is favored by female patients, and is more and more advocated by gynecologic surgeons.

The single-port laparoscopic surgery can be broadly classified into a laparoendoscopic single-site surgery (LESS) and a Natural Orifice Transluminal Endoscopic Surgery (NOTES), and the single-port laparoscope in many hospitals tends to replace the multi-port laparoscope. One of the greatest advantages of both is the advantage of their surgical access. The transumbilical single-port laparoscopic surgery utilizes the navel as an operation access, the total length of an incision is smaller compared with that of a multi-port laparoscopic surgery, and the natural fold of the navel can well hide an operation incision scar and can better meet the requirement of a female patient on beauty, so that the single-port laparoscopic surgery is more and more widely applied to the treatment of gynecological benign diseases. Secondly, the navel is the weakest part of the human body surface, and the vascular nerves are sparsely distributed, so the injury of the operation access of the single-hole laparoscopic surgery to the muscles, the nerves, the blood vessels and the like is smaller, and the pain of the postoperative patient is obviously reduced compared with the pain of the porous laparoscopic surgery; different from the step of establishing observation holes by blind puncture in the porous laparoscopic surgery, the single-hole laparoscopic surgery operation is to incise the abdominal wall layer by layer under the direct vision to enter the abdominal cavity, thereby greatly reducing the risk of puncture injury of abdominal viscera. The endoscopic surgery through the natural cavity is a surgery which is performed by entering the pelvic cavity and the abdominal cavity through the natural cavities of the oral cavity, the stomach, the vagina and the like of a patient, and has the advantages of postoperative scar hiding, light pain, no scar on the body surface, quick postoperative recovery and the like. After the concept is proposed, the surgery is performed through a vaginal natural orifice endoscopic surgery (vnets), also called a transvaginal single-port laparoscopic surgery, and is widely applied to gynecological surgery.

In recent years, the operations of uterus and attachments (attachments refer to oviduct and ovary) have been widely applied in the transumbilical single-port laparoscopic surgery and the transvaginal single-port laparoscopic surgery, and the operations related to benign tumors and malignant tumors are involved. Hysteromyoma, adenomyosis and benign tumor of ovary are the most common reasons for the operation treatment of female patients caused by gynecological benign diseases, but in most cases, the diameter of the solid tumor or the size of a pathological uterine body far exceeds the incision of a single-port laparoscopic operation (the incision of the single-port laparoscopic operation is about 2.5cm, generally not more than 3cm, and the main operation indication of the uterine tumor or ovarian tumor is that the diameter of the tumor is more than or equal to 5 cm), and even the situation that the diameter of a tumor sample needing to be taken out of the body is more than 10cm and 15cm is frequently encountered in clinical work, so how to take out the excised sample from a small incision is one of the difficulties frequently encountered in the laparoscopic operation and is a more time-consuming step. In clinical work, it takes 10 minutes for resection of the tumor to occur, while the specimen removal step takes 1 hour or more. Generally, when a larger solid tissue specimen is taken out through a smaller incision, the specimen must be cut into a smaller size (such as a cold cutting apple mode which is commonly used in clinic) to be taken out from the incision smoothly, but the principle of no tumor is very important in the whole operation process, if the tumor is cut in a patient body under the condition of no protective measures, some tissue fragments and/or liquid containing tumor cells are scattered in the pelvic cavity of the patient (as a laparoscope is filled with an intestinal canal, a omentum and other visceral organs, even if a large amount of sterile water is used for washing, the tumor is difficult to be completely cleaned up), if the tumor is benign, the tumor can be scattered and planted in the pelvic cavity, the patient needs to perform multiple subsequent operation treatments, and great influence is brought to the mind and body of the patient; if the cancer is malignant tumor, multiple planting and metastasis of malignant tumor cells can be caused, i.e. iatrogenic causes cause change from early stage to late stage, which seriously affects the prognosis of the patient and is a devastating hit for the patient. Therefore, whether benign or malignant, there must be adequate safeguards before the tumor is cut to ensure that no tissue debris and/or tissue fluid is scattered within the patient.

In the prior art, in order to satisfy the principle of no tumor, in a multi-hole laparoscope (usually three or more holes) operation, a sealed rotary-cut bag is usually matched with an electric grinder to cut and take out a tumor in the sealed rotary-cut bag to achieve the purpose of isolation protection, in this way, a larger sealed rotary-cut bag needs to be fully unfolded in the laparoscope, then two finger ends are pulled out of the laparoscope from corresponding incisions and inflated into the sealed rotary-cut bag to expand the sealed rotary-cut bag, then the electric grinder can be inserted, the whole operation process needs to be very careful, the sealed rotary-cut bag is prevented from being torn, the isolation protection effect cannot be achieved, so the existing mode needs to prevent the electric grinder from contacting the sealed rotary-cut bag (the sealed rotary-cut bag is damaged once the sealed rotary-cut bag is contacted), the operation is complex, and time and labor are consumed, and there is a risk of the barrier bag breaking; more importantly, this approach is not suitable for single port laparoscopic surgery. In addition, in the prior art, a technical means for taking out a large-size solid tumor (or called as a solid specimen) from a single-port laparoscopic surgery is lacked under the condition of meeting a tumor-free principle, so that the process for taking out the large-size solid tumor (especially when the size of the solid tumor is larger than that of a single-port laparoscopic incision) is long in time consumption and low in efficiency, and the problems of improper protection and residual tissue fragments or liquid containing tumor cells in a patient body are very easy to occur, and the problem needs to be solved urgently.

step 1, medical personnel send an isolation protection bag 200 into a patient body 102 through an incision 104, and put a solid tumor 105 which is cut off from the body and needs to be taken out into the isolation protection bag 200 through a bag opening 202, as shown in fig. 2 and 3, and tighten the bag opening to prevent the tumor or tissue fluid containing tumor cells from leaking; the operation is carried out in the body 102, so that the operation is carried out under the assistance of an endoscope, and a tool such as a clamp can pull the bag opening 202, so that the solid tumor 105 can be loaded into the isolation protection bag 200 through the bag opening 202, and the solid tumor 105 loaded into the isolation protection bag 200 is isolated from a patient, so that the purpose of isolating the solid tumor 105 is achieved;

step 2, pulling the bag mouth 202 of the isolation protection bag 200 out of the body 103 through the notch 104, as shown in fig. 3; in the single-port laparoscopic surgery, only one incision 104 is provided, for example, the incision 104 is provided at the navel, so that the medical staff can only pull the bag mouth 202 of the isolation protection bag 200 out of the body 103 through the incision 104, and in the operation process, the bag mouth 202 can be clamped by using auxiliary tools such as forceps and the like so as to pull out the bag mouth 202 by using the forceps;

step 3, after the bag opening 202 is placed outside the patient body 103, the medical care personnel can pull the isolation and protection bag 200 outwards through the bag opening 202 so as to tighten the isolation and protection bag 200 outwards, as shown in fig. 4 and 5, so that the solid tumor 105 in the isolation and protection bag 200 can be pulled to a position close to and corresponding to the incision 104, so that the medical care can directly see the solid tumor 105 inside through the incision 104 without the assistance of an endoscope, as shown in fig. 5 and 6, and the subsequent cutting is facilitated; correspondingly, in order to facilitate subsequent cutting, the outward tensioning state of the isolation protection bag 200 can be kept, the tumor position can be fixed conveniently for cutting, and the risk that the isolation protection bag is damaged by mistake is reduced, so that the solid tumor 105 in the isolation protection bag 200 can be always positioned at the position corresponding to the cut 104 for continuous cutting, and similarly, the opening 202 can be kept in the opening state, so that the solid tumor 105 can be conveniently checked, medical staff can perform continuous cutting conveniently, the efficiency is improved, and the operation time is shortened;

in this step, in order to tension barrier protection bag 200 outward, a preferred mode of operation is to tension barrier protection bag 200 by rolling up bag opening 202, as shown in fig. 4-6, and to place bag opening 202 in an open state; specifically, after the bag mouth 202 of the isolation protection bag 200 is pulled out of the incision 104, the bag mouth 202 can be manually rolled up and rolled in a direction close to the incision 104, so that a part of the isolation protection bag 203 outside the body 103 can be rolled into a ring shape, as shown in fig. 4-6, in this way, not only can the bag mouth 202 be kept in a good open state to provide a larger operation space for the cutting process, but also the isolation protection bag 200 can be continuously tightened outwards in the process of rolling up the bag mouth 202, so that the purpose of outwards tensioning can be achieved, and the solid tumor 105 in the isolation protection bag 200 can be always positioned at the position of the solid tumor 105, so that a medical staff can directly view the solid tumor 105, and thus the cutting of the solid tumor 105 is facilitated; after the rolling operation is completed, the partial isolation protection bag 203 rolled into a ring shape outside the body 103 can be fixed by auxiliary devices such as adhesive tapes, so as to achieve the purpose of fixing, thereby keeping the isolation protection bag 200 in an outward tensioning state and keeping the bag mouth 202 in an opening state.

Step 4, the medical staff can extend the cutting tool into the isolation protection bag 200 through the bag opening 202, so that under the condition of visual observation, the cutting tool is used for directly cutting the solid tumor 105 in the isolation protection bag 200, and the cut small tumor tissues are taken out one by one through the bag opening 202 until the solid tumor 105 remained in the isolation protection bag 200 can pass through the incision 104;

in the specific operation process, the cutting tool adopted by the medical staff can be a scalpel or scissors and the like, so that manual cutting can be performed through the incision 104, the cut small tumor tissues can be of a long strip structure or a small block structure, cutting is facilitated, the cut small tumor tissues of the long strip structure or the small block structure can more conveniently pass through the incision 104, the cut small tumor tissues can be efficiently taken out from the isolation protection bag 200, and the purpose of efficiently decomposing and taking out the solid tumor 105 in the body is achieved.

Because the isolation protection bag 200 has good cutting resistance and good liquid seepage resistance, the solid tumor 105 with large volume is taken out by directly cutting the solid tumor 105 in the isolation protection bag 200, on one hand, under the condition of directly observing the solid tumor 105, medical personnel can directly cut the solid tumor 105 in the isolation protection bag 200 by using a cutting tool without using an endoscope for assistance and considering the problem of whether the isolation protection bag 200 is cut, so that the process of decomposing the solid tumor 105 with large volume is simpler, more time-saving and more labor-saving, the solid tumor 105 can be efficiently taken out from a single hole, the efficiency is improved, the operation time and the anesthesia time are shortened, and the postoperative rapid recovery of a patient is facilitated; on the other hand, the better isolation and protection effect can be realized, so that the process of taking out the large-volume solid tumor 105 in the single-port laparoscopic surgery process conforms to the tumor-free principle, the important problem is closely related to the prognosis of a patient, and the technical problem which cannot be solved by the prior art is creatively solved.

Step 5, the medical staff can pull the isolation protection bag 200 outwards so as to pull out the whole isolation protection bag 200 through the incision 104, so that the solid tumor 105 and the liquid containing tumor cells and the like remained in the isolation protection bag 200 can be separated from the patient along with the isolation protection bag 200, and the large-volume solid tumor 105 in the patient can be successfully taken out through a single hole, high efficiency and no tumor; in a more sophisticated version, after removal of the isolation and protection bag, the integrity of the isolation and protection bag needs to be checked to ensure that no pieces of tumor tissue or tissue fluid containing tumor cells have scattered inside the abdominal cavity.

In a more perfect scheme, in the isolation protection bag 200 provided in this embodiment, a soft ring 205 is further disposed at the bag opening 202, the soft ring 205 may be made of rubber or a silica gel material, and since the soft ring 205 is annular and the soft ring 205 has elasticity, the soft ring 205 may automatically open the bag opening 202, so as to conveniently load a tumor into the isolation protection bag 200 without manually opening the bag opening 202, which is beneficial to more convenient use.
