Description

Technical Field

[0001] The invention relates to the technical field of polluted gas monitoring, and in particular to a method for removing a large solid tumor in a body through a single hole. Background Art

[0002] With the rapid development of modern medical technology, the average life expectancy of human beings has gradually increased. People are no longer satisfied with the treatment of diseases only for the efficacy, but also have higher and higher requirements for the quality of life after treatment. Therefore, when choosing a surgical method, both doctors and patients, in addition to considering the treatment of the disease itself, pay more and more attention to the impact on the quality of life, and prefer to choose a more minimally invasive method, which also prompts surgeons to constantly seek surgical methods with less trauma and faster recovery. In the field of gynecology, laparoscopic surgery has become one of the main surgical methods, especially in benign gynecological diseases, laparoscopic surgery is a safe and reliable mainstream choice. In recent years, with the continuous improvement of laparoscopic surgery technology and the increasing updating of surgical instruments, single-port laparoscopic surgery has developed by leaps and bounds. Compared with multi-port laparoscopic surgery, single-port laparoscopic surgery has less trauma and more concealed and beautiful incisions, which is quite popular among female patients, and therefore more and more respected by gynecological surgeons.

[0003] Single-port laparoscopic surgery can be broadly divided into transumbilical single-site laparoscopic surgery (laparoendoscopic single-site surgery, LESS) and natural orifice transluminal endoscopic surgery (natural orifice transluminalendoscopic surgery, NOTES). In many hospitals, single-port laparoscopy has replaced multi-port laparoscopy. One of the biggest advantages of both is the advantage of their surgical access. Transumbilical single-port laparoscopic surgery uses the navel as the surgical access, and the total length of its incision is smaller than that of multi-port laparoscopic surgery. In addition, the natural wrinkles of the navel can well hide the surgical incision scar, which can better meet the pursuit of beauty of female patients. Therefore, single-port laparoscopic surgery is more and more widely used in the treatment of benign gynecological diseases. Secondly, the navel is the weakest part of the human body, and the blood vessels and nerves are sparsely distributed. Therefore, the surgical approach of single-port laparoscopic surgery causes less damage to muscles, nerves, blood vessels, etc., and the pain felt by patients after surgery is significantly reduced compared to multi-port laparoscopic surgery. Unlike the blind puncture step of establishing an observation hole in multi-port laparoscopic surgery, the operation of single-port laparoscopic surgery is to cut the abdominal wall layer by layer under direct vision to enter the abdominal cavity, which also greatly reduces the risk of puncture of abdominal organs. Endoscopic surgery through natural cavities refers to entering the pelvic and abdominal cavities through the patient's mouth, stomach, vagina and other natural cavities to perform surgery. It has the advantages of hidden postoperative scars, mild pain, no scars on the body surface, and fast postoperative recovery. After this concept was proposed, vaginal natural orifice transluminal edoscopic surgery (vNOTES), also known as vaginal single-port laparoscopic surgery, has been widely used in gynecological surgery.

[0004] In recent years, transumbilical single-port laparoscopic surgery and transvaginal single-port laparoscopic surgery have been widely used in surgeries of the uterus and adnexa (adnexa refer to fallopian tubes and ovaries), involving surgery of benign and malignant tumors. Uterine fibroids, adenomyosis, and benign ovarian tumors are the most common reasons for female patients to undergo surgical treatment for benign gynecological diseases. In most cases, the diameter of the solid tumor or the size of the lesioned uterine body far exceeds the incision of single-port laparoscopic surgery (the incision of single-port laparoscopic surgery is about 2.5 cm long, generally not more than 3 cm, and the main surgical indication for uterine or ovarian tumors is a tumor diameter ≥ 5 cm). In clinical work, it is often encountered that the diameter of the tumor specimen that needs to be removed from the body is > 10 cm or 15 cm. Therefore, how to remove the resected specimen from a smaller incision is one of the difficulties often encountered in laparoscopic surgery, and it is also a more time-consuming step. In clinical work, it is common to see that it takes 10 minutes to remove the tumor, while the specimen removal step takes 1 hour or even longer. Usually, when taking out a larger solid tissue specimen through a smaller incision, it must first be cut into a smaller size (such as the cold knife method commonly used in clinical practice to peel an apple) in order to be taken out smoothly from the incision. However, the tumor-free principle is very important throughout the operation. If the tumor is cut in the patient's body without protective measures, some tissue fragments and / or fluid containing tumor cells will be scattered in the patient's pelvic and abdominal cavity (because the laparoscope is full of intestines, omentum and other organs, it is difficult to completely clean it up even if a large amount of sterile water is used for flushing). If it is a benign tumor, it may cause the tumor to spread and implant in the pelvic and abdominal cavity, and the patient will need multiple subsequent surgeries, which will have a great impact on the patient's body and mind; if it is a malignant tumor, it may cause malignant tumor cells to implant and metastasize in multiple places, that is, iatrogenic causes cause the early stage to become the late stage, seriously affecting the patient's prognosis, which is a devastating blow to the patient. Therefore, whether it is a benign tumor or a malignant tumor, proper protective measures must be taken before cutting the tumor to ensure that no tissue fragments and / or tissue fluid are scattered in the patient's body.

[0005] In the prior art, in order to meet the tumor-free principle, in multi-port laparoscopic (usually three or more ports) surgery, a closed exfoliating bag and an electric pulverizer are usually used to mince and remove the tumor in the closed exfoliating bag to achieve the purpose of isolation and protection. In this method, a larger closed exfoliating bag must be fully unfolded in the laparoscope, and then two fingertips are pulled out of the body from the corresponding incisions, and then the closed exfoliating bag is inflated to expand the closed exfoliating bag before the electric pulverizer can be inserted. The entire operation process needs to be very careful to prevent the closed exfoliating bag from being torn, which fails to achieve the effect of isolation and protection. Therefore, the existing method needs to prevent the electric pulverizer from contacting the closed exfoliating bag (once contacted, the closed exfoliating bag will be damaged). Not only is the operation complicated, but it is also time-consuming and labor-intensive, and there is a risk of rupture of the isolation bag; more importantly, this method is not suitable for single-port laparoscopic surgery. Moreover, the prior art lacks the technical means to remove larger solid tumors (or solid specimens) from single-port laparoscopic surgery while meeting the tumor-free principle, resulting in a long and inefficient process for removing larger solid tumors (especially when the size of the solid tumor is larger than the single-port laparoscopic incision). It is also very easy to have problems such as improper protection and residual tissue fragments or fluid containing tumor cells in the patient's body, which urgently needs to be solved. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that the prior art lacks technical means for removing a large solid tumor from a single-port laparoscopic surgery under the premise of ensuring the principle of tumor-free, resulting in a long time-consuming and inefficient process for removing a large solid tumor, and it is very easy to have improper protection, and tissue fragments or liquid containing tumor cells remain in the patient's body. A method for removing a large solid tumor from the body through a single port is provided, which can isolate and protect a large solid tumor, and can conveniently and efficiently remove the solid tumor through a single port, and is particularly suitable for single-port laparoscopic surgery. The main concept is:

[0007] A method for removing a large solid tumor in vivo through a single hole, comprising an operation kit, the operation kit comprising an isolation protection bag, the isolation protection bag having an internal accommodating cavity and a bag opening communicating with the internal accommodating cavity, and the isolation protection bag being resistant to cutting; the method comprising the following steps:

[0008] Step 1: insert the isolation protection bag into the body through the incision, put the solid tumor to be removed from the body into the isolation protection bag, and tighten the bag opening;

[0009] Step 2, pulling the bag opening of the isolation protection bag out of the body through the incision;

[0010] Step 3, pulling the isolation protection bag outward, and pulling the solid tumor to the position corresponding to the incision, keeping the isolation protection bag in a state of being stretched outward, and keeping the bag opening in an open state;

[0011] Step 4: insert the cutting tool into the isolation protection bag through the bag opening, use the cutting tool to cut the solid tumor, and take out the cut small piece of tumor tissue through the bag opening until the solid tumor remaining in the isolation protection bag can pass through the incision;

[0012] Step 5, pull the isolation protection bag outward, and pull out the entire isolation protection bag through the incision. In the present solution, by setting up an isolation protection bag, and the isolation protection bag is constructed with only one bag opening, it can not only adapt to the incision of single-port laparoscopic surgery, but also can conveniently put the resected solid tumor into the isolation protection bag in the body, so as to achieve the purpose of isolating the solid tumor; and by constructing the isolation protection bag to be resistant to cutting, it is not easy for medical staff to damage the isolation protection bag when cutting the solid tumor in the isolation protection bag, and there will be no problem of tumor tissue fragments or tissue fluid containing tumor cells scattering in the abdominal cavity, thereby greatly reducing the risk of tumor dissemination caused by the isolation protection bag being torn or cut and affecting the patient's prognosis; in addition, the isolation protection bag with this structure is particularly suitable for single-port laparoscopic surgery with only a single small incision; and with this structure of isolation protection After the bag is formed, on the one hand, medical staff can directly use cutting tools to cut the solid tumor in the isolation protection bag while looking directly at the solid tumor, without the assistance of laparoscope, and because of the anti-cutting characteristics of the isolation protection bag with this structure, there is no need to worry about whether the isolation protection bag will be damaged. Therefore, there is no need to cut carefully as in the prior art, making the process of decomposing large solid tumors simpler, time-saving and labor-saving, and solid tumors can be efficiently removed from a single hole, greatly improving efficiency, shortening operation time and anesthesia time, and facilitating the patient's rapid recovery after surgery; on the other hand, better isolation and protection effects can be achieved, so that the process of removing large solid tumors during single-port laparoscopic surgery complies with the tumor-free principle, thereby effectively solving the problems existing in the prior art.

[0013] In order to prevent the liquid containing tumor cells from remaining in the patient's body during the cutting process, the isolation protection bag is further impermeable to liquid. That is, the isolation protection bag has good liquid-proof performance to prevent the liquid containing tumor cells from penetrating into the patient's body through the isolation protection bag during the cutting of a solid tumor in the isolation protection bag, which is conducive to achieving a better isolation protection effect.

[0014] In order to make the isolation protection bag have good cutting resistance, preferably, the isolation protection bag is made of high-strength polyethylene material or Kevlar material.

[0015] Preferably, the isolation protection bag is a long strip structure, and the bag opening is configured at one end of the isolation protection bag. The isolation protection bag with a long strip structure is convenient for both placing the solid tumor into the isolation protection bag and pulling the isolation protection bag out, so that the solid tumor can be fixed at the incision, which is more convenient for subsequent cutting and removal.

[0016] In order to solve the problem that the medical staff can cut the solid tumor in the isolation protection bag and remove it smoothly under direct vision, in the scheme 1, in the step 3, the isolation protection bag is tightened by rolling up the bag mouth, and the bag mouth is in an open state. By rolling up the bag mouth, not only can the bag mouth be kept in a good open state to provide a larger operating space for the cutting process, but also in the process of rolling up the bag mouth, the isolation protection bag can be continuously tightened outwards, so as to achieve the purpose of outward tension, so that the solid tumor in the isolation protection bag can always be fixed at a position close to the surface incision, so that the medical staff can directly see the solid tumor, which is more convenient for cutting the solid tumor.

[0017] In the second solution, the operating kit further includes a tensioning mechanism, and the tensioning mechanism includes a bracket and an installation portion disposed on the bracket and used for installation, wherein:

[0018] The stent is configured with an operating channel, and the diameter of the operating channel is greater than the diameter of the incision. At least three pulling assemblies are configured along the circumferential direction of the operating channel, and each of the pulling assemblies includes a retractor, and the retractor is connected to the stent respectively.

[0019] At least three hanging ears are respectively constructed on the inner side of the isolation protection bag, and each of the hanging ears is respectively adapted to each of the draw hooks;

[0020] The process of outwardly tensioning the isolation protection bag in step 3 comprises the following steps:

[0021] 3.1 The bracket is fixedly mounted through the mounting portion, and the cutout is located on the inner side of the operating channel;

[0022] 3.2 Pull the isolation protection bag outward to pull the solid tumor to the position of the incision, and hook the corresponding ear. In this solution, by fixing the bracket in the tensioning mechanism, a basis can be provided for tensioning the isolation protection bag, and by constructing an operating channel and making the incision located on the inner side of the operating channel, and the diameter of the operating channel is larger than the diameter of the incision, the tensioning mechanism will not interfere with or hinder the operation of medical staff, and it is convenient for medical staff to perform cutting operations through the operating channel; by providing a hook on the tensioning mechanism and a ear on the inner side of the isolation protection bag, the cooperation between the hook and the ear can effectively tension the isolation protection bag outward. On the one hand, after tensioning, the solid tumor is fixed at a position close to the incision, so that the medical staff can look directly at the solid tumor in the isolation protection bag for cutting; and the tensioning of the isolation protection The process of protecting the bag does not require the assistance of an assistant, which frees up the assistant's hands, saving manpower and avoiding the risk of accidental injury to the assistant's hands when fixing the bag opening during the cutting process. In addition, the bag opening is open for a long time, is more stable, and has a better opening effect, which can provide a larger operating space for the cutting process. On the other hand, since the hanging ear is constructed on the inner side of the isolation protection bag, when the hanging ear is connected to the corresponding hook, the part of the isolation protection bag between the hanging ear and the bag opening will be pressed under the hanging ear and the hook, so that while being tensioned, the isolation protection bag outside the body can also be constrained, thereby effectively preventing the isolation protection bag outside the body from affecting medical staff in performing cutting and other operations, and reducing the risk of accidental injury or cutting of the isolation protection bag.

[0023] To facilitate the connection between the hook and the ear, the pulling assembly further includes a pulling rope, the hook is connected to one end of the pulling rope, and the other end of the pulling rope is connected to the bracket. By providing the pulling rope, the hook can be moved arbitrarily, which makes it easier for the hook to match the ear.

[0024] In order to solve the problem that the solid tumor in the isolation protection bag is continuously pressed against the incision during the cutting process, in Solution 1, the pulling rope is an elastic rope. The pulling rope has a certain elasticity. After being connected to the hanging ear, it can not only provide continuous elastic tension for the isolation protection bag, but also when the volume of the solid tumor in the isolation protection bag becomes smaller, the isolation protection bag can be automatically tensioned under the elastic force of the pulling rope, so that during the cutting process, the solid tumor in the isolation protection bag is always at the incision and continuously pressed against the incision, which is more convenient for medical staff to cut.

[0025] In the second solution, the pulling assembly further includes a spring, and the pulling rope is connected to the bracket via the spring. By providing the spring, the elastic force of the spring can be used to tension the isolation protection bag, and when the volume of the solid tumor in the isolation protection bag becomes smaller, the isolation protection bag can be automatically tensioned under the elastic force of the spring, so that during the cutting process, the solid tumor in the isolation protection bag is always at the incision and continuously pressed against the incision, which is more convenient for medical staff to cut.

[0026] Preferably, the support is a circular ring structure so as to fit the incision that is stretched into a circle.

[0027] Preferably, several groups of hanging ears are configured along the depth direction of the isolation protection bag, each group of hanging ears includes at least three hanging ears, and the hanging ears in each group are evenly distributed along the circumferential direction of the isolation protection bag; and / or the pulling components are evenly distributed along the circumferential direction of the operation channel. This allows the isolation protection bag to be evenly stressed and evenly tensioned along the circumferential direction of the incision, so as to occupy less incision space.

[0028] Preferably, the mounting portion is an adhesive layer disposed on the bracket so as to be fixed to the patient's body surface by gluing, thereby achieving the purpose of fixing the tensioning mechanism.

[0029] In order to facilitate the efficient removal of the cut small tumor tissue from the isolation protection bag, further, in step 4, the cut small tumor tissue is in a long strip structure or a small block structure. Not only is it easy to cut, but the tumor tissue in a long strip structure or a small block structure is more convenient to pass through the incision, so that the cut small tumor tissue can be efficiently removed from the isolation protection bag, achieving the purpose of efficiently decomposing the solid tumor in the body.

[0030] Preferably, the cutting tool is a scalpel or scissors, so as to perform manual cutting through the incision.

[0031] In order to solve the problem of facilitating the delivery of the isolation protection bag into the body through the incision, the operation kit further includes an operation rod, which includes an outer sleeve and a push-pull rod, wherein:

[0032] The outer sleeve is configured with a guide channel adapted to the push-pull rod and a cavity for accommodating the isolation protection bag, the cavity is connected to the guide channel, and the cavity and the guide channel respectively pass through both ends of the outer sleeve, and the outer diameter of the outer sleeve is smaller than the diameter of the incision;

[0033] The push-pull rod is movably constrained in the guide channel, the isolation protection bag is wrapped and folded on the front end of the push-pull rod and constrained in the cavity, the rear end of the push-pull rod extends out of the outer sleeve, and the rear end of the push-pull rod is configured with a handle;

[0034] In step 1, the process of delivering the isolation protection bag into the body through the incision includes the following steps:

[0035] 1.1 Insert the front end of the operating rod into the abdominal cavity through the incision;

[0036] 1.2 Hold the outer sleeve with one hand and the handle with the other hand, and push the push-pull rod inward through the handle so that the front end of the push-pull rod extends out of the outer sleeve, so as to release the isolation protection bag constrained in the cavity in the abdominal cavity;

[0037] 1.3 Turn the push-pull rod to unfold the isolation protection bag in the abdominal cavity. In this solution, an outer sleeve and a push-pull rod that can move relatively are constructed in the operating rod, and a cavity that can accommodate the isolation protection bag is constructed at the front end of the outer sleeve, so that initially, the isolation protection bag can be wrapped and folded around the front end of the push-pull rod, and the front end of the push-pull rod is just located in the cavity, so that the isolation protection bag can remain in a folded state under the dual constraints of the push-pull rod and the outer sleeve, and the outer diameter of the outer sleeve is smaller than the diameter of the incision, so that the outer sleeve can be conveniently inserted into the patient's abdominal cavity through the incision, thereby achieving the purpose of efficiently and conveniently delivering the isolation protection bag into the patient's body; by constructing a handle at the rear end of the push-pull rod, The push-pull rod can be moved relative to the guide channel, so that when the front end of the operating rod is inserted into the patient's body, the medical staff can hold the outer sleeve with one hand and the handle with the other hand, and push the push-pull rod inward through the handle, so that the push-pull rod can move relative to the outer sleeve, so that the front end of the push-pull rod can extend out of the outer sleeve. At this time, the constraint of the outer sleeve on the isolation protection bag disappears, so that the isolation protection bag wrapped and folded on the push-pull rod can be automatically released in the body; then, only the push-pull rod needs to be rotated appropriately to make the isolation protection bag unfold in the body, so that the solid tumor to be removed can be placed in the isolation protection bag later.

[0038] To simplify the operation, a connecting rope is further provided at the bag opening of the isolation protection bag, and the connecting rope is connected to the front end of the push-pull rod. By providing the connecting rope, the push-pull rod and the isolation protection bag are connected as one body through the connecting rope, which is convenient for unfolding the isolation protection bag in the body and for pulling the bag opening of the isolation protection bag out of the body by using the push-pull rod; and when the bag opening is pulled out of the body, the connecting rope can be cut with scissors, thereby releasing the connection between the push-pull rod and the isolation protection bag, making it easier to operate the isolation protection bag separately in the future, such as rolling up the bag opening, tightening the isolation protection bag, etc.

[0039] Compared with the prior art, the method for removing a large solid tumor from the body through a single port provided by the present invention can not only isolate and protect a larger solid tumor, but also directly cut, decompose and remove the large solid tumor under direct vision under the premise of strictly abiding by the tumor-free principle, and can conveniently and efficiently remove a large solid tumor from the body through a small incision. This method can greatly improve efficiency, shorten operation time and anesthesia time, and facilitate rapid postoperative recovery of patients, and can achieve better isolation and protection effects, which is conducive to improving the prognosis of patients. This operation makes the process of removing large solid tumors during single-port laparoscopic surgery more standardized and strictly abides by the tumor-free principle. It is not only suitable for multi-port laparoscopic surgery, but also suitable for single-port laparoscopic surgery. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0058] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0059] Example 1

[0060] See also Figure 1-Figure 6 In this embodiment, an operation kit is provided, including an isolation protection bag 200, wherein the isolation protection bag 200 is configured with an internal accommodating cavity 201 and a bag opening 202 connected to the internal accommodating cavity 201, such as Figure 1 As shown, in actual use, the solid tumor 105 to be removed can be conveniently placed in the isolation protection bag 200 in the body 102 to achieve the purpose of isolating the solid tumor 105; in specific implementation, the isolation protection bag 200 can preferably adopt a long strip structure, for example, Figure 1 As shown, the isolation protection bag 200 can be a cylindrical structure with one end closed and the other end having a bag opening 202, which is convenient for loading the solid tumor 105 into the isolation protection bag 200 and tightening the bag opening 202, and for pulling the isolation protection bag 200 outward, so that the solid tumor 105 can be against the incision 104, which is more convenient for subsequent removal; it can be understood that in order to load a larger volume of solid tumor 105, the inner diameter of the isolation protection bag 200 is larger than the diameter of the incision 104, and the specific value can be determined according to actual needs, as long as it can accommodate a large volume solid tumor 105 of corresponding size (the large volume solid tumor 105 described in this embodiment refers to a solid tumor 105 whose size is larger than the diameter of the incision 104. These solid tumors 105 cannot be directly taken out from the incision 104, and must be cut before they can be successfully taken out, which will not be repeated in the following text).

[0061] In this embodiment, the isolation protection bag 200 is constructed to be resistant to cutting, that is, the isolation protection bag 200 is constructed to have good cutting resistance, so that medical staff can cut the solid tumor 105 on the isolation protection bag 200 without damaging the isolation protection bag 200 and without leakage problems, thereby greatly reducing the risk of tumor dissemination caused by the isolation protection bag 200 being torn or cut and affecting the patient's prognosis.

[0062] In order to prevent liquid containing tumor cells from remaining in the patient's body 102 during the cutting process, in a more perfect solution, the isolation protection bag 200 should also be impermeable; that is, the isolation protection bag 200 has good liquid-proof performance to prevent the liquid containing tumor cells from penetrating into the patient's body 102 through the isolation protection bag 200 during the cutting of the solid tumor 105 in the isolation protection bag 200, which is conducive to achieving better isolation and protection effects; and in order to facilitate folding, storage and passing through the incision 104, the isolation protection bag 200 should also be constructed to be flexible.

[0063] In order to make the isolation protection bag 200 have good cutting resistance, good anti-liquid seepage performance and good flexibility, the material of the isolation protection bag 200 can be considered, and the isolation protection bag 200 can also be a single-layer structure or a multi-layer structure, so that the isolation protection bag 200 has a variety of implementation methods. For example, the material of the isolation protection bag 200 includes high-strength polyethylene (HPPE). High-strength and high-modulus polyethylene chemical fiber (HPPE) is a very good chemical fiber resistant to cutting material, which can at least be used as one of the inner layer materials of the isolation protection bag 200. For example, the isolation protection bag 200 can include at least one layer of high-strength polyethylene layer. The inner layer of 200 can be a high-strength polyethylene layer; of course, glass fiber, spandex or steel wire can also be coated in the high-strength polyethylene layer to achieve better anti-cut effect. For example, glass fiber can be coated in the high-strength polyethylene to form a cotton yarn layer with stronger cut resistance together with the high-strength polyethylene, and the cotton yarn layer can be used as the inner layer of the isolation protection bag 200 to improve the cut resistance performance; in specific implementation, the isolation protection bag 200 made of high-strength polyethylene (HPPE) material itself has certain anti-liquid seepage performance and flexibility, and in order to achieve better anti-liquid seepage effect, the outer layer of the isolation protection bag 200 can be provided with a waterproof coating or waterproof film to further prevent leakage.

[0064] For another example, the material of the isolation protection bag 200 includes Kevlar material, which also has extraordinary wear resistance and cut resistance, and its compressive strength is 15 times that of stainless steel plates of the same quality. At the same time, it has good ductility and is easier to use. In a specific implementation, the inner layer of the isolation protection bag 200 can be a Kevlar material layer to improve the cut resistance of the inner layer; in a specific implementation, the isolation protection bag 200 made of Kevlar material itself has a certain anti-liquid seepage performance, and in order to achieve a better anti-liquid seepage effect, accordingly, the outer layer of the isolation protection bag 200 can be provided with a layer of waterproof coating or waterproof film to further prevent leakage.

[0065] For another example, the material of the isolation protection bag 200 includes nitrile material, for example, it can be the same material as nitrile gloves, and can at least be used as one of the inner layer materials of the isolation protection bag 200, with good cut resistance, liquid-proof performance and good flexibility; and in order to achieve better liquid-proof effect, accordingly, the outer layer of the isolation protection bag 200 can be provided with a waterproof coating or waterproof film to further prevent leakage.

[0066] The operation kit provided in this embodiment is particularly suitable for single-port laparoscopic surgery with only a single incision 104. Therefore, according to the operation kit provided in this embodiment, this embodiment further provides a method for removing a large solid tumor 105 in vivo through a small incision, the method comprising the following steps:

[0067] Step 1: The medical staff delivers the isolation protection bag 200 into the patient's body 102 through the incision 104, and puts the solid tumor 105 that needs to be removed from the body into the isolation protection bag 200 through the bag opening 202. Figure 2 and Figure 3 As shown, the bag mouth is tightened to prevent the tumor or tissue fluid containing tumor cells from leaking out; this step of operation is performed in the body 102, so it needs to be implemented with the assistance of a laparoscope, and the bag mouth 202 can be pulled by tools such as forceps, so that the solid tumor 105 can be loaded into the isolation protection bag 200 through the bag mouth 202. After being loaded into the isolation protection bag 200, the solid tumor 105 is isolated from the patient, thereby achieving the purpose of isolating the solid tumor 105;

[0068] Step 2: Pull the bag opening 202 of the isolation protection bag 200 out of the body 103 through the incision 104. Figure 3 As shown; in the single-port laparoscopic surgery, there is only one incision 104, such as the incision 104 opened at the navel, so the medical staff can only pull the bag opening 202 of the isolation protection bag 200 out of the body 103 through the incision 104. During the operation, auxiliary tools such as forceps can be used to clamp the bag opening 202 so as to pull the bag opening 202 out with the forceps;

[0069] Step 3: After the bag opening 202 is placed outside the patient's body 103, the medical staff can pull the isolation protection bag 200 outward through the bag opening 202 to tighten the isolation protection bag 200 outward. Figure 4 and Figure 5 As shown, the solid tumor 105 in the isolation protection bag 200 can be pulled to a position close to and corresponding to the incision 104, so that the medical staff can directly see the solid tumor 105 inside through the incision 104 without the assistance of laparoscope, as shown in FIG. Figure 5 and Figure 6As shown, it is convenient for subsequent cutting; accordingly, to facilitate subsequent cutting, the isolation protection bag 200 can be kept in a state of being tensioned outwards, which is conducive to fixing the tumor position for cutting and reducing the risk of the isolation protection bag being accidentally damaged, so that the solid tumor 105 in the isolation protection bag 200 can always be located at the position corresponding to the incision 104 for continuous cutting. Similarly, the bag opening 202 can be kept in an open state, which is convenient for viewing the solid tumor 105 and is conducive to continuous cutting by medical staff, so as to improve efficiency and shorten the operation time;

[0070] In this step, in order to tension the isolation protection bag 200 outward, a preferred operation method is to tension the isolation protection bag 200 by rolling up the bag opening 202, such as Figure 4-Figure 6 Specifically, when the bag opening 202 of the isolation protection bag 200 is pulled out of the incision 104, the bag opening 202 can be manually rolled up and rolled in a direction close to the incision 104, so that the isolation protection bag 203 outside the body 103 can be rolled into a ring, as shown. Figure 4-Figure 6 As shown, by adopting this method, not only can the bag mouth 202 be kept in a good open state to provide a larger operating space for the cutting process, but also in the process of rolling up the bag mouth 202, the isolation protection bag 200 can be continuously tightened outwards, so as to achieve the purpose of outward tensioning, so that the solid tumor 105 in the isolation protection bag 200 can always be in the position of the solid tumor 105, so that the medical staff can directly see the solid tumor 105, thereby making it easier to cut the solid tumor 105; when the rolling operation is completed, the isolation protection bag 203 rolled into a ring outside the body 103 can be fixed by auxiliary equipment such as tape to achieve the purpose of fixing, so that the isolation protection bag 200 can be kept in a state of outward tensioning, and the bag mouth 202 can be kept in an open state.

[0071] Step 4: The medical staff can insert the cutting tool into the isolation protection bag 200 through the bag opening 202, so as to cut the solid tumor 105 directly in the isolation protection bag 200 with the cutting tool under visual observation, and take out the cut small pieces of tumor tissue one by one through the bag opening 202 until the solid tumor 105 remaining in the isolation protection bag 200 can pass through the incision 104;

[0072] During the specific operation process, the cutting tools used by medical staff can be scalpels or scissors, so as to perform manual cutting through the incision 104, and the small pieces of tumor tissue cut off can be in the form of long strips or small blocks, which is not only convenient for cutting, but also makes it easier for tumor tissue with long strips or small blocks to pass through the incision 104, so that the small pieces of tumor tissue cut off can be efficiently removed from the isolation protection bag 200, thereby achieving the purpose of efficiently decomposing and removing the solid tumor 105 in the body.

[0073] Since the isolation protection bag 200 has good cutting resistance and good anti-liquid seepage performance, the large solid tumor 105 is removed by directly cutting the solid tumor 105 in the isolation protection bag 200. On the one hand, the medical staff can directly use the cutting tool to cut the solid tumor 105 in the isolation protection bag 200 while looking directly at the solid tumor 105, without the need to use the laparoscope for assistance, and without considering whether the isolation protection bag 200 will be damaged. Therefore, there is no need to perform careful cutting as in the prior art, making the process of decomposing the large solid tumor 105 simpler, time-saving, and labor-saving, so that the solid tumor 105 can be efficiently removed from a single hole, which is beneficial to improving efficiency, shortening the operation time and anesthesia time, and facilitating the patient's rapid recovery after surgery; on the other hand, a better isolation and protection effect can be achieved, so that the process of removing the large solid tumor 105 during the single-port laparoscopic surgery complies with the tumor-free principle, and this important issue is closely related to the patient's prognosis, thereby creatively solving the technical problems that the prior art cannot solve.

[0074] Step 5. Medical staff can pull the isolation protection bag 200 outward so as to pull out the entire isolation protection bag 200 through the incision 104, so that the solid tumor 105 and the fluid containing tumor cells remaining in the isolation protection bag 200 can be separated from the patient along with the isolation protection bag 200, thereby successfully removing the large-volume solid tumor 105 from the patient's body through a single-hole, efficient, and tumor-free method; in a more complete solution, after removing the isolation protection bag, it is necessary to check the integrity of the isolation protection bag to determine that no tumor tissue fragments or tissue fluid containing tumor cells are scattered in the abdominal cavity.

[0075] In a more complete solution, in the isolation protection bag 200 provided in this embodiment, a soft ring 205 is further provided at the bag opening 202. The soft ring 205 can be made of rubber or silicone material. Since the soft ring 205 is ring-shaped and elastic, the soft ring 205 can automatically open the bag opening 202, making it convenient to put the tumor into the isolation protection bag 200 without manually opening the bag opening 202, which is conducive to more convenient use.

[0076] Example 2

[0077] In order to solve the problem of facilitating the outward tensioning of the isolation protection bag 200, the main difference between the present embodiment 2 and the above-mentioned embodiment 1 is that the operating kit provided in the present embodiment further includes a tensioning mechanism, and the tensioning mechanism includes a bracket 300 and an installation portion disposed on the bracket 300 and used for installation, wherein:

[0078] The mounting portion is mainly used to realize the installation and fixation of the support frame, so as to provide a basis for the subsequent tensioning of the isolation protection bag 200; the mounting portion has various embodiments, for example, the mounting portion can be an adhesive layer provided on the support 300, so as to be fixed to the patient's body surface 101 by pasting, so as to achieve the purpose of fixing the tensioning mechanism, such as Fig. 9 or Fig.10 As shown; for another example, the mounting portion can be an adjustable belt commonly used in the prior art, and both ends of the adjustable belt are respectively connected to the bracket 300. In actual use, the adjustable belt can be put on the patient's waist and tightened, so that the bracket 300 can be placed on the patient's body surface 101.

[0079] like Fig. 9 or Fig.10 As shown, the bracket 300 is configured with an operation channel 301, and the diameter of the operation channel 301 is larger than the diameter of the incision 104. At least three pulling components 302 are configured along the circumferential direction of the operation channel 301. Each of the pulling components 302 includes a hook 303, and the hook 303 is connected to the bracket 300. Correspondingly, at least three hanging ears 204 are configured on the inner side of the isolation protection bag 200. Figure 7 and Figure 8 As shown, each of the hanging ears 204 is matched with each of the hooks 303 , so that in actual use, the isolation protection bag 200 can be tensioned outwardly on the bracket 300 through the cooperation between the hanging ears 204 and the hooks 303 .

[0080] In this embodiment, the bracket 300 plays a role in bearing the force and preventing the structure from deforming. Therefore, the shape of the bracket 300 can be determined according to actual needs. As a preferred embodiment, Fig. 9 or Fig.10 As shown, the bracket 300 may be a circular ring structure so as to fit into the circular incision 104 .

[0081] In a preferred embodiment, a plurality of groups of hanging ears 204 are configured along the depth direction of the isolation protection bag 200, each group of hanging ears 204 includes at least three hanging ears 204, and each hanging ear 204 in each group is evenly distributed along the circumferential direction of the isolation protection bag 200; accordingly, each pulling assembly 302 can be evenly distributed along the circumferential direction of the operating channel 301, so that the isolation protection bag 200 is evenly stressed and can be evenly tensioned along the circumferential direction of the incision 104, so as to occupy less space of the incision 104; in specific implementation, the number of hanging ears 204 and pulling assembly 302 can be determined according to actual needs, for example, Figure 7 and Figure 8As shown, in the present embodiment, the bracket 300 is constructed with four pulling assemblies 302, and the four pulling assemblies 302 are evenly distributed along the circumferential direction of the operating channel 301; correspondingly, three groups of hanging ears 204 are respectively constructed along the depth direction of the isolation protection bag 200, and the spacing between each group of hanging ears 204 is the same, each group of hanging ears 204 includes at least four hanging ears 204, and the four hanging ears 204 in each group are evenly distributed along the circumferential direction of the isolation protection bag 200, so as to cooperate with the corresponding pulling assemblies 302, and the spacing between each group of hanging ears 204 and the bag opening 202 can be determined according to actual needs.

[0082] To facilitate the connection between the hook 303 and the ear 204, in a further embodiment, the pulling assembly 302 further includes a pulling rope 304, the hook 303 is connected to one end of the pulling rope 304, and the other end of the pulling rope 304 is connected to the bracket 300. Fig. 9 or Fig.10 As shown, by providing a pulling rope 304, the pull hook 303 can be moved arbitrarily, so that the pull hook 303 is more convenient to match with the hanging ear 204, which is conducive to more convenient use.

[0083] According to the operation kit provided in this embodiment, accordingly, this embodiment further provides a method for removing a large solid tumor 105 in vivo through a single hole. The method is the same as the method described in Example 1, and the method is more perfect, mainly in that, in the method, the process of tensioning the isolation protection bag 200 outward in step 3 can specifically include the following steps:

[0084] 3.1 Medical staff can fix the mounting bracket 300 through the mounting portion and make the incision 104 located on the inner side of the operating channel 301, such as Fig. 9 or Fig.10 As shown, that is, the operation channel 301 corresponds to the incision 104 and is connected to the incision 104 for subsequent operations;

[0085] 3.2 Pull the isolation protection bag 200 outward to pull the solid tumor 105 to the position of the incision 104, and make the hook 303 hook the corresponding ear 204, as shown in FIG. Fig. 9 or Fig.10As shown, the tensioning mechanism is used to tension the isolation protection bag 200 outward. On the one hand, after tensioning, the solid tumor 105 can be exactly at the position of the incision 104, so that the medical staff can directly see the solid tumor 105 in the isolation protection bag 200 for cutting without the assistance of a laparoscope; and the process of tensioning the isolation protection bag 200 does not require the assistance of additional personnel, which not only saves manpower, but also allows the isolation protection bag 200 to maintain a tensioned state outward for a long time and stably; on the other hand, because the hanging ear 204 is constructed on the inner side of the isolation protection bag 200, when the hanging ear 204 is connected to the corresponding retractor 303, the part of the isolation protection bag 200 between the hanging ear 204 and the bag opening 202 will be pressed under the hanging ear 204 and the retractor 303, as shown in FIG. Fig. 9 or Fig.10 As shown, while being tensioned, the isolation protection bag 200 outside the body 103 can also be constrained, thereby effectively preventing the isolation protection bag 200 outside the body 103 from affecting operations such as cutting by medical staff.

[0086] In order to ensure that the solid tumor 105 in the isolation protection bag 200 can be continuously pressed against the incision 104 during the cutting process, in a preferred embodiment, the pulling rope 304 can be an elastic rope, so that the pulling rope 304 has a certain elasticity. After being connected to the hanging ear 204, it can not only provide continuous elastic tension for the isolation protection bag 200, but also when the volume of the solid tumor 105 in the isolation protection bag 200 becomes smaller, under the action of the elastic force of the pulling rope 304, the isolation protection bag 200 can automatically be tensioned outward, so that during the cutting process, the solid tumor 105 in the isolation protection bag 200 can always be at the incision 104 and continuously pressed against the incision 104, which makes it easier for medical staff to cut the tumor efficiently.

[0087] In another preferred embodiment, the pulling assembly 302 further includes a spring 305. Fig.10 As shown, the pulling rope 304 can be connected to the bracket 300 through the spring 305 so as to utilize the elastic force of the spring 305 to tension the isolation protection bag 200, and when the volume of the solid tumor 105 in the isolation protection bag 200 becomes smaller, under the elastic force of the spring 305, the isolation protection bag 200 can be automatically tensioned, so that during the cutting process, the solid tumor 105 in the isolation protection bag 200 is always at the incision 104 and continuously pressed against the incision 104, which is more convenient for medical staff to cut.

[0088] Specifically, the two ends of the spring 305 can be directly connected to the pulling rope 304 and the bracket 300, or can be indirectly connected to the pulling rope 304 and the bracket 300, and the spring 305 can be a compression spring 305 or a tension spring 305, such as Fig.10As shown; and in order to meet the needs of different patients, in a further embodiment, as Fig.11 and Fig.12 As shown, the pulling assembly 302 also includes a guide portion constructed on the bracket 300, a slider 307 adapted to the guide portion, and a locking mechanism. The guide portion is arranged along the radial direction of the operating channel 301, so that the slider 307 constrained by the guide portion can move radially, and the two ends of the spring 305 can be connected to the pulling rope 304 and the slider 307 respectively. The locking mechanism is used to lock / unlock the slider 307, which can not only adjust the radial position of the slider 307, but also stably lock the position of the slider 307; the locking mechanism has multiple implementation methods. As an example, the locking mechanism includes a locking bolt 310 and a bar hole 309 constructed on the bracket 300 and corresponding to the slider 307. The slider 307 is configured with a threaded hole 308, such as Fig.11 and Fig.12 As shown, the locking bolt 310 is adapted to the threaded hole 308, and the locking bolt 310 passes through the bar hole 309 and is inserted into the threaded hole 308. When the locking bolt 310 is tightened or loosened, the slider 307 and the locking bolt 310 can move together along the guide portion to adjust the position of the slider 307; when the adjustment is in place, the slider 307 can be locked by tightening the locking bolt 310. With such a design, the position of the slider 307 can be adaptively adjusted according to different users, thereby achieving the purpose of adjusting the preload force of the spring 305 and adjusting the initial tension force of the isolation protection bag 200, so as to improve the versatility of the operating kit and the method.

[0089] In a specific implementation, the guide portion may be a guide rail adapted to the slider 307, or a slide groove 306 adapted to the slider 307. For example, Fig.11 and Fig.12 As shown, the guide portion adopts a sliding groove 306 adapted to the sliding block 307 .

[0090] Example 3

[0091] In order to solve the problem of facilitating the delivery of the isolation protection bag 200 into the body 102 through the incision 104, the main difference between the present embodiment 3 and the above-mentioned embodiment 1 or embodiment 2 is that the operation kit provided in the present embodiment further includes an operation rod 400, and the operation rod 400 includes an outer sleeve 401 and a push-pull rod 404, wherein:

[0092] like Figure 13-Figure 15As shown, the outer sleeve 401 is constructed with a guide channel 403 adapted to the push-pull rod 404 and a cavity 402 for accommodating the isolation protection bag 200. The cavity 402 is connected to the guide channel 403, and the cavity 402 and the guide channel 403 respectively pass through the two ends of the outer sleeve 401. As shown in the figure, the outer sleeve 401 can preferably adopt a round tube, and the outer diameter of the outer sleeve 401 is smaller than the diameter of the incision 104, so that the operating rod 400 can be inserted into the patient's body 102 through the incision 104; when a laparoscopic surgical operation channel is established at the incision 104, the outer diameter of the outer sleeve 401 should also be smaller than the inner diameter of the laparoscopic surgical operation channel to facilitate smooth passage.

[0093] like Figure 13-Figure 15 As shown, the push-pull rod 404 is movably constrained in the guide channel 403, so that the push-pull rod 404 has the freedom to move relative to the outer sleeve 401, and initially, the isolation protection bag 200 can be wrapped and folded around the front end of the push-pull rod 404 and constrained in the cavity 402, and the rear end of the push-pull rod 404 extends out of the rear end of the outer sleeve 401, and the rear end of the push-pull rod 404 is configured with a handle 405, as shown in FIG. Fig.13 and Fig.14 As shown, it is convenient for medical staff to hold.

[0094] Based on the operation kit provided in this embodiment, in the method for removing a large solid tumor 105 in the body through a small incision, in step 1, the process of delivering the isolation protection bag 200 into the body 102 through the incision 104 may include the following steps:

[0095] 1.1 The medical staff can insert the front end of the operating rod 400 into the abdominal cavity through the incision 104; in this embodiment, when a laparoscopic operation channel is established in the incision 104, the front end of the operating rod 400 can be inserted into the patient's body 102 through laparoscopic operation;

[0096] 1.2 The medical staff can hold the outer sleeve 401 with one hand and the handle 405 with the other hand, and push the push-pull rod 404 inward through the handle 405 so that the front end of the push-pull rod 404 extends out of the outer sleeve 401, so as to release the isolation protection bag 200 constrained in the cavity 402 in the body 102;

[0097] 1.3 The medical staff can rotate the push-pull rod 404 so that the isolation protection bag 200 is separated from the push-pull rod 404 and unfolded in the body 102.

[0098] Specifically, in this embodiment, by constructing an outer sleeve 401 and a push-pull rod 404 that can move relatively in the operating rod 400, and constructing a cavity 402 that can accommodate the isolation protection bag 200 at the front end of the outer sleeve 401, the isolation protection bag 200 can be wrapped and folded around the front end of the push-pull rod 404 at the beginning, and the front end of the push-pull rod 404 is just located in the cavity 402, so that the isolation protection bag 200 can maintain a folded state under the dual constraints of the push-pull rod 404 and the outer sleeve 401, as shown in FIG. Fig.14 and Fig.15 As shown, the outer diameter of the outer sleeve 401 is smaller than the diameter of the incision 104, so that the outer sleeve 401 can be conveniently inserted into the patient's body 102 through the incision 104, thereby achieving the purpose of efficiently and conveniently delivering the isolation protection bag 200 into the patient's body 102 through the single incision 104; by constructing a handle 405 at the rear end of the push-pull rod 404, and allowing the push-pull rod 404 to move relative to the guide channel 403, when the front end of the operating rod 400 is inserted into the patient's body 102, the medical staff can hold the outer sleeve 401 with one hand and hold the handle with the other hand 405, by pushing the push-pull rod 404 inwardly through the handle 405, the push-pull rod 404 can be moved relative to the outer sleeve 401, so that the front end of the push-pull rod 404 can extend out of the outer sleeve 401. At this time, the constraint of the outer sleeve 401 on the isolation protection bag 200 disappears, so that the isolation protection bag 200 wrapped and folded on the push-pull rod 404 can be automatically released in the body 102; then, it is only necessary to rotate the push-pull rod 404 appropriately to make the isolation protection bag 200 unfold in the body 102, so that the solid tumor 105 can be subsequently placed in the isolation protection bag 200.

[0099] In a specific implementation, there may be no connection between the isolation protection bag 200 and the push-pull rod 404, so that when the isolation protection bag 200 is separated from the push-pull rod 404 in the body 102, the entire operating rod 400 can be withdrawn from the patient's body 102 through the incision 104; of course, there may also be a connection between the isolation protection bag 200 and the push-pull rod 404, for example, a connecting rope 406 is further provided at the bag opening 202 of the isolation protection bag 200, such as Fig.16 As shown, the connecting rope 406 is connected to the front end of the push-pull rod 404, so that the isolation protection bag 200 can be connected to the push-pull rod 404 as a whole through the connecting rope 406, which is convenient for unfolding the isolation protection bag 200 in the body 102, and for using the push-pull rod 404 to pull the bag opening 202 of the isolation protection bag 200 out of the body 103; and when the bag opening 202 is pulled out of the body 103, the connecting rope 406 can be cut with scissors, thereby releasing the connection between the push-pull rod 404 and the isolation protection bag 200, which is more convenient for subsequent operations on the isolation protection bag 200 alone, such as rolling up the bag opening 202, tightening the isolation protection bag 200, etc.

[0100] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
