Technical Field

[0001] The present application relates to the technical field of tumor removal from the body, and in particular to a tumor bagging and cutting device for surgery. Background Art

[0002] In traditional tumor cutting surgery, the cut tumor is taken out of the abdominal cavity, usually by expanding the size of the prying opening, which is very traumatic and leaves a long scar on the patient's belly, affecting the appearance. At present, for large tumors in the abdominal cavity, the tumor is generally cut into small pieces and then taken out of the abdominal cavity. For example, the patent application with publication number CN111685853A discloses a device for crushing and aspirating abdominal tumors, which opens the upper connecting plate and the lower connecting plate, props up the transparent elastic cover, expands the volume in the transparent elastic cover, and expands the feed port at the same time. The doctor can put the tumor tissue cut into suitable large pieces into the transparent elastic cover through the feed port. Then the motor is started by the motor switch, the rotation of the motor drives the gear to rotate, the gear drives the gear stick to rotate, the gear stick drives the swivel and the rotating tube to rotate, the swivel drives four crushing knives to rotate, the crushing knives will crush the tumor tissue put into the transparent elastic cover, and then start the suction pump to suck the crushed tumor tissue into the collection bag. The solution disclosed in this application involves rotating four pulverizing knives inside the patient's body, which has a high risk of scratching the transparent elastic cover. This can cause the pulverized tumor tissue to scatter in the human abdominal cavity, triggering the growth of multiple tumors, and may also accidentally cut normal tissue and internal organs. Summary of the invention

[0003] In view of the fact that the scheme of mincing tumor tissue involves rotating four mincing knives inside the patient's body, there is a high risk of scratching the transparent elastic cover, which will cause the minced tumor tissue to scatter in the human abdominal cavity, triggering the growth of multiple tumors, and may also accidentally cut normal tissues and internal organs. The present application proposes a wire-cut tumor bagging cutting device and adopts the following technical solution.

[0004] A surgical tumor bagging and cutting device comprises an inner memory wire, an outer memory wire, an inner bag, an outer bag, a core tube, a plurality of first direction cutting ropes and a plurality of second direction cutting ropes.

[0005] The bag opening of the inner bag has an inner ring cavity; the inner memory wire is passed through the inner ring cavity, and both ends of the inner memory wire pass through the core tube.

[0006] The bag opening of the outer bag is provided with an outer ring cavity; the outer memory wire is passed through the outer ring cavity, and both ends of the outer memory wire pass through the core tube.

[0007] The outer bag is sleeved outside the inner bag; the middle sections of the first-direction cutting ropes and the middle sections of the second-direction cutting ropes are both located inside the inner bag; the first-direction cutting ropes and the second-direction cutting ropes are in different layers and have different directions; both ends of the first-direction cutting ropes and both ends of the second-direction cutting ropes pass through the inner ring cavity and penetrate into the core tube.

[0008] By adopting the above technical solution, when the device is applied to tumor surgery, for a tumor that has been cut off and is still inside the human body, the outer bag and the inner bag can be inserted into the location of the tumor in the human body together. The tumor can be loaded into the inner bag through devices such as clips. The mouth ends of the outer bag and the inner bag are pulled out, the first-direction cutting ropes and the second-direction cutting ropes are pulled out of the core tube, and the first-direction cutting ropes and the second-direction cutting ropes are used to cut the tumor. After cutting the tumor into small strips, it is taken out. The method of cutting the tumor with a wire has a relatively high safety factor. The inner bag protects the outer bag and prevents the first-direction cutting ropes and the second-direction cutting ropes from damaging the outer bag when cutting the tumor, so that the chopped tumor does not leak out of the outer bag, improving the safety of the cutting operation.

[0009] A preferred solution of the tumor bagging and cutting device for surgery is that a plurality of notches are provided at the mouth of the inner bag. The inner memory wire passes through each notch. Both ends of the first-direction cutting ropes and both ends of the second-direction cutting ropes penetrate into the inner ring cavity from each notch.

[0010] By adopting the above technical solution, the inner bag can be sleeved on the inner memory wire, and both ends of the first-direction cutting ropes and both ends of the second-direction cutting ropes are also accommodated, which is also convenient for later pulling out the first-direction cutting ropes and the second-direction cutting ropes for wire sawing operations.

[0011] A preferred solution of the tumor bagging and cutting device for surgery is that the inner surface of the inner bag has a plurality of grooves in the first direction and a plurality of grooves in the second direction. The number of the first-direction cutting ropes is the same as the number of the grooves in the first direction. The number of the second-direction cutting ropes is the same as the number of the grooves in the second direction. In the initial state, the middle sections of the plurality of first-direction cutting ropes are respectively embedded in the plurality of grooves in the first direction, and the middle sections of the plurality of second-direction cutting ropes are respectively embedded in the plurality of grooves in the second direction.

[0012] By adopting the above technical solution, in the initial state, the positions of the first-direction cutting ropes and the second-direction cutting ropes are relatively fixed and not easily offset or entangled.

[0013] A preferred embodiment of the tumor bagging and cutting device for surgery is that the tumor bagging and cutting device for surgery includes a handle tube; the handle tube is threadedly connected to one end of the core tube away from the inner bag. Both ends of the inner memory wire, both ends of the outer memory wire, both ends of each first-direction cutting rope, and both ends of each second-direction cutting rope pass through the handle tube and are fixed.

[0014] By adopting the above technical solution, the inner memory wire, the outer memory wire, each first-direction cutting rope, and each second-direction cutting rope are all fixed, and it is not easy to have problems such as wire disconnection and deviation during the process of entering the human body.

[0015] A preferred embodiment of the tumor bagging and cutting device for surgery is that the tumor bagging and cutting device for surgery includes a sleeve; the sleeve is sleeved outside the core tube; by pulling the core tube, the inner memory wire, the outer memory wire, the inner bag, and the outer bag can all be compressed and enter the sleeve.

[0016] By adopting the above technical solution, the device can be stored in a smaller volume, that is, it is stored in the sleeve. Its cross-sectional area is small, the incision required on the human body is small, and the harm to the human body and the impact on the skin aesthetics are reduced.

[0017] A preferred embodiment of the tumor bagging and cutting device for surgery is that a column is fixed on the outer surface of the handle tube; both ends of the inner memory wire, both ends of the outer memory wire, both ends of each first-direction cutting rope, and both ends of each second-direction cutting rope are wound and fixed on the column.

[0018] By adopting the above technical solution, when the device is inserted into human tissue, the ends of the inner memory wire, the ends of the outer memory wire, the ends of each first-direction cutting rope, and the ends of each second-direction cutting rope are wound and fixed on the column. When wire sawing operation is to be performed, the ends of the inner memory wire, the ends of the outer memory wire, the ends of each first-direction cutting rope, and the ends of each second-direction cutting rope can be disassembled from the column, and these wire ropes can be separated from the sleeve and the core tube to perform wire sawing operation.

[0019] A preferred embodiment of the tumor bagging and cutting device for surgery is that the tumor bagging and cutting device for surgery further includes a protector. The protector includes a plurality of unit components. Each unit component includes a flat plate portion and a fan-shaped curved plate portion that are connected to each other. All the fan-shaped curved plate portions are used to be inserted between the inner bag and the outer bag and spliced into a cylindrical shape. All the flat plate portions are spliced into an annular shape and are used to indirectly press on the skin around the human incision.

[0020] By adopting the above technical solution, when cutting a tumor, at the wound, the cutting rope is in close contact with the inner bag and the outer bag, and the inner bag is prone to breakage, which may in turn cause the outer bag to break. The protector is provided to protect the outer bag, which does not affect tumor cutting and can also protect the outer bag to prevent the cut tumor debris from entering the human tissue.

[0021] A preferred solution of the tumor bagging and cutting device for surgery is that the surface of each of the flat parts has a movable latch, a guide block, a stop block and an insertion block. The movable latch passes through the guide block. The movable latch is restricted to move between the guide block and the stop block. When the movable latch abuts against the stop block, the movable latch is located within the flat part. When the movable latch abuts against the guide block, the movable latch inserts into the insertion block of the adjacent flat part, making the adjacent flat parts relatively fixed.

[0022] By adopting the above technical solution, all the unit parts can be separately placed between the inner bag and the outer bag, and after being placed, they can be spliced together to play a supporting role.

[0023] A preferred solution of the tumor bagging and cutting device for surgery is that the inner circumference of each of the flat parts has a low-order arc surface. The low-order arc surfaces of all the flat parts are spliced into a low-order toroidal surface. The tumor bagging and cutting device for surgery further includes a fixator. The fixator has a star-shaped round head and an insertion rod connected to each other. The star-shaped round head has a wavy edge, the wave crests of the wavy edge abut against the low-order toroidal surface, and the wave troughs are located within the low-order toroidal surface, so that a plurality of holes are formed between the wavy edge and the low-order toroidal surface. The two ends of each of the first-direction cutting ropes and the two ends of each of the second-direction cutting ropes are disengaged from the core tube and the inner ring cavity and respectively pass through the plurality of holes.

[0024] By adopting the above technical solution, the insertion rod of the fixator can be inserted into the tumor to fix the tumor so that it can be easily cut, and the cutting ropes can pass through the holes to perform left-right stretching cutting operations.

[0025] A preferred solution of the tumor bagging and cutting device for surgery is that the middle sections of the first-direction cutting ropes and the middle sections of the second-direction cutting ropes are perpendicular to each other. The two ends of each of the first-direction cutting ropes pass through the two sides of the wavy edge in the first direction. The two ends of each of the second-direction cutting ropes pass through the two sides of the wavy edge in the second direction.

[0026] By adopting the above technical solution, the first-direction cutting ropes cut the tumor in the first direction, and the second-direction cutting ropes cut the tumor in the second direction, that is, the tumor is cut horizontally and vertically into small square strips so as to take out the tumor from the wound.

[0027] In summary, the tumor bagging and cutting device for surgery of the present application has the following beneficial effects: The tumor is cut by a wire cutting method, and the safety factor is relatively high; the inner bag protects the outer bag and prevents the first-direction cutting rope and the second-direction cutting rope from damaging the outer bag when cutting the tumor, and the chopped tumor does not leak out of the outer bag, improving the safety of the cutting operation.

Detailed implementation mode

[0041] The technical solutions in the embodiments will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the following embodiments, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0042] As Figure 1 and Figure 2 shown in Figure 3 FIGs.

[0043] As Figure 2 shown in

[0044] shown in Figure 3 FIGs. Figure 4, on both sides of the outer surface of the handle tube 8, columns 11 are fixed. The two end heads of the inner memory wire 1 are wound and fixed on the columns 11 on either one side or both sides to prevent it from shifting towards the bag mouth end and getting tangled. When a cutting operation is required, the end heads of the wound inner memory wire 1 can be untied, and the inner memory wire 1 can be detached from the core tube 5, but the wire body of the inner memory wire 1 remains in the upper edge of the inner layer bag 3 at the bag mouth to facilitate the unfolding of the bag mouth of the inner layer bag 3 without interfering with the wire cutting of the tumor.

[0045] As Figure 5 , the cutting device of this embodiment has four first-direction cutting ropes 6 and four second-direction cutting ropes 7. In other embodiments, the cutting device can also include three first-direction cutting ropes 6 and three second-direction cutting ropes 7, or other numbers, which can be specifically set and selected according to the size of the tumor.

[0046] As Figure 2 , the inner layer bag 3 can be made of silica gel material, and its inner surface has horizontally and vertically intersecting grooves 301, for example, four horizontal grooves 301 and four vertical grooves 301. The horizontal and vertical directions can be in a three-dimensional arc shape to match the shape of the bag body.

[0047] The middle sections of the four first-direction cutting ropes 6 are embedded in the four horizontal grooves 301, and the middle sections of the four second-direction cutting ropes 7 are embedded in the four vertical grooves 301. The two ends of the four first-direction cutting ropes 6 and the two ends of the four second-direction cutting ropes 7 first enter the notch 101, then pass through the notch 101 into the inner ring cavity 102, then pass through the core tube 5, and finally pass out of the handle tube 8 and are wound and fixed on the columns 11 on either one side or both sides of the outer surface of the handle tube 8. When cutting the tumor is required, the four first-direction cutting ropes 6 and the four second-direction cutting ropes 7 that are wound can be untied, and the two ends of the four first-direction cutting ropes 6 and the two ends of the four second-direction cutting ropes 7 can be pulled out of the inner ring cavity 102, that is, the two ends of the four first-direction cutting ropes 6 and the two ends of the four second-direction cutting ropes 7 are detached from the inner layer bag 3, but the middle sections of the cutting ropes still remain inside the inner wall of the inner layer bag 3, so that the tumor that has been clamped into the inner layer bag 3 can be cut.

[0048] The outer layer bag 4 can be made of polyethylene material. The outer layer bag 4 is sleeved outside the inner layer bag 3. The middle section of the outer memory wire 2 passes through the upper edge of the outer layer bag 4 at the bag mouth, and the two ends of the outer memory wire 2 pass through the core tube 5, then pass out of the handle tube 8 and are wound and fixed on the columns 11. When a cutting operation is required, the two ends of the wound outer memory wire 2 can be untied, and the outer memory wire 2 can be detached from the core tube 5, but it remains in the upper edge of the outer layer bag 4 at the bag mouth to facilitate the unfolding of the bag mouth of the outer layer bag 4. During the operation, the upper part of the outer layer bag 4 is spread and attached to the skin around the wound without interfering with the wire cutting of the tumor.

[0049] The surgical tumor bagging and cutting device is used for cutting and removing tumors that have been cut but remain in the human body. It needs to be inserted into the tumor of the human body. In order to reduce the trauma to the human body, a small incision is generally made. The device needs to be stored and reduced in size, mainly reduced to a rod with a small cross-sectional area, and then sent into the human body, and then unfolded inside the human body. Therefore, in a preferred embodiment, the surgical tumor bagging and cutting device also includes a sleeve 10, which is adaptively sleeved outside the core tube 5. The sleeve 10 also has a blocking ring, and the handle tube 8 can abut against the blocking ring and cannot move forward. At this time, the inner bag 3 and the outer bag 4 just completely extend out of the sleeve 10, and the blocking ring can prevent the core tube 5 from being excessively inserted into the human body.

[0050] The first direction cutting rope 6 and the second direction cutting rope 7 should be relatively thin. In the initial state, they are embedded in each strip groove 301 of the inner bag 3. The inner memory wire 1 and the outer memory wire 2 are straightened and parallel to the core tube 5, and the inner bag 3 and the outer bag 4 are wound outside the outer memory wire 2 to form a rod-shaped coil. The core tube 5 is pulled to shrink the rod-shaped coil into the sleeve 10, so that the device can pass through the opened wound in a rod-shaped form with a smaller cross section. Then, the core tube 5 is pushed to make the rod-shaped coil detach from the sleeve 10, and the inner memory wire 1 and the outer memory wire 2 can be automatically unfolded, that is, the inner bag 3 and the outer bag 4 can be driven to unfold, so that the tumor 9 that has been cut can be loaded.

[0051] like Figure 6 When the tumor 9 is cut online, the wound is narrow and the cutting rope is easy to scratch the inner bag 3, which may cause the inner bag 3 to be damaged, and then may also cause the outer bag 4 to be damaged. Therefore, the tumor bagging and cutting device also provides a protector 12 between the inner bag 3 and the outer bag 4, specifically at a position adjacent to the wound.

[0052] The protector 12 should be inserted between the inner bag 3 and the outer bag 4 in the wound, and should be fixed outside the wound and should not be completely sunken into the wound. Figure 7 The protector 12 is designed to be smaller at the wound and larger at the lower end to protect the outer bag 4. The protector 12 cannot be directly inserted into the wound as an integral part, so it is designed as four separate units 121. Figure 8 Each unit element 121 includes a flat plate portion 1211 and a fan-shaped curved plate 1212 connected to each other. The fan-shaped curved plate 1212 is used to be inserted between the inner bag 3 and the outer bag 4, and four fan-shaped curved plates 1212 are spliced ​​into a cylindrical shape. All flat plates 1211 are spliced ​​into a circular ring, which is used to press on the upper part of the unfolded outer bag 4 and is located on the skin around the wound of the human body.

[0053] like Figure 8, in order to make the shape of the four unit components 121 stable after splicing, an active latch 1213, a guide block 1214, a stop block 1215 and an insertion block 1216 are further provided on the upper surface of each flat plate portion 1211. The active latch 1213 is L-shaped. Both the guide block 1214 and the insertion block 1216 have slotted holes. One long side of the active latch 1213 passes through the slotted hole of the guide block 1214. When the active latch 1213 moves, the other short side of the active latch 1213 abuts against the guide block 1214 or the stop block 1215, so that the active latch 1213 moves between the guide block 1214 and the stop block 1215. When the active latch 1213 abuts against the guide block 1214, the active latch 1213 is inserted into the slotted hole of the insertion block 1216 of another unit component 121, so that two adjacent unit components 121 are relatively fixed. When the active latch 1213 abuts against the stop block 1215, the active latch 1213 disengages from the insertion block 1216 of another unit component 121, and the active latch 1213 is completely located within the flat plate portion 1211, then two adjacent unit components 121 can be freely separated.

[0054] When cutting the tumor 9 by wire cutting, it is necessary to fix the tumor 9 to provide a supporting force for conveniently cutting the tumor 9. Therefore, the device is designed such that the inner circumference of each flat plate portion 1211 is a low-order arc surface, and the outer circumference of each flat plate portion 1211 is a high-order plane, forming a stepped structure. As Figure 7 , the four low-order arc surfaces of the four flat plate portions 1211 enclose a low-order toroidal surface 1217.

[0055] As Figure 9 , the device further includes a fixator 13. The fixator 13 has a star-shaped round head 131 and an insertion rod 132. The star-shaped round head 131 is flat, the insertion rod 132 is vertically fixed at the center of the star-shaped round head 131, and the end of the insertion rod 132 away from the star-shaped round head 131 has insertion teeth, which can be inserted into the tumor 9 to fix the tumor 9. The star-shaped round head 131 has a wavy edge, for example, sixteen wave crests 1311 and sixteen wave troughs 1312. Pass the insertion rod 132 of the fixator 13 through the middle cavity surrounded by the four sector-shaped curved plates 1212, as Figure 10 , the star-shaped round head 131 abuts against the low-order toroidal surface 1217, specifically, each wave crest 1311 abuts against the low-order toroidal surface 1217, as Figure 11 , each wave trough 1312 is located between the low-order toroidal surfaces 1217, that is, the wave trough 1312 does not contact the low-order toroidal surface 1217, so that a plurality of holes 14 are formed between the wavy edge and the low-order toroidal surface 1217, for example, sixteen holes 14. Each hole 14 can pass out a cutting rope for cutting the tumor 9 operation.

[0056] The tumor bagging and cutting device for surgery cooperates with a rod-shaped clip, etc. to perform the operation of cutting the tumor 9. The specific application method is as follows.

[0057] As Figure 12 , make a first incision 15 at 9 locations of the abdominal tumors in the human body, cut off the tumor 9 and retain it in the abdominal cavity, and make a second incision 16 and a third incision 17 on the human abdomen. These three incisions are all relatively small to reduce the harm to the human body and the impact on the aesthetics of the skin. Then the three incisions can be triangular in shape.

[0058] The inner bag 3 and the outer bag 4 are both wound and stored in the sleeve 10. Insert the surgical tumor bagging and cutting device with the inner bag 3 and the outer bag 4 compressed from the second incision 16 to the position of the tumor 9. Keep the sleeve 10 stationary, and push the handle tube 8 so that the inner bag 3 and the outer bag 4 completely extend out of the sleeve 10. Under the action of the inner memory wire 1 and the outer memory wire 2, the inner bag 3 and the outer bag 4 unfold.

[0059] Insert the rod-shaped clip from the third incision 17 to the tumor 9, clamp the tumor 9 into the inner bag 3, and withdraw the rod-shaped clip.

[0060] Pull the sleeve 10 and the handle tube 8, pull out the inner memory wire 1 and the outer memory wire 2 from the second incision 16, untie the two ends of the inner memory wire 1, the two ends of the outer memory wire 2, the two ends of the first-direction cutting rope 6, and the two ends of the second-direction cutting rope 7 on the upright column 11, so that they are all detached from the handle tube 8. Unscrew the handle tube 8, take out the sleeve 10 and the core tube 5, and pull out the two ends of each first-direction cutting rope 6 and the two ends of each second-direction cutting rope 7 from the inner ring cavity 102, so that the middle sections of each first-direction cutting rope 6 and each second-direction cutting rope 7 are located in the bag body of the inner bag 3, and the two ends of each first-direction cutting rope 6 and the two ends of each second-direction cutting rope 7 are completely exposed on the inner bag 3.

[0061] The outer memory wire 2 unfolds outside the second incision 16 and lies flat around the second incision 16.

[0062] Insert each unit member 121 of the protector 12 between the outer bag 4 and the inner bag 3 in sequence. Specifically, the fan-shaped curved panel 1212 of each unit member 121 is inserted between the outer bag 4 and the inner bag 3 in sequence. The four fan-shaped curved panels 1212 are assembled into a cylinder with a large depth and a small superficial part. During the assembly process, pull out the two ends of each first-direction cutting rope 6 and the two ends of each second-direction cutting rope 7 from this cylinder.

[0063] The above assembly process is also accompanied by: the flat plate parts 1211 of the four unit members 121 are flatly attached to the upper part of the unfolded outer bag 4 around the second incision 16, enclosing a large ring, and the inner circumference of this large ring is a low-order toroidal surface 1217. Move each movable latch 1213 so that it is inserted into the insertion block 1216 of the adjacent unit member 121, so that the four unit members 121 are relatively assembled and fixed.

[0064] Insert the insertion rod 132 of the fixator 13 into the cylinder body. The end of the insertion rod 132 stabs the tumor 9, and the star-shaped round head 131 of the fixator 13 presses on the lower-order toroidal surface 1217. A plurality of holes 14 are formed between the wavy edge of the star-shaped round head 131 and the lower-order toroidal surface 1217, for example, sixteen holes 14. In this process, each end of each first-direction cutting rope 6 and each end of each second-direction cutting rope 7 pass through a hole 14 respectively. For example, the eight ends of the four first-direction cutting ropes 6 and the eight ends of the four second-direction cutting ropes 7 pass through the sixteen holes 14 one by one according to the orientation.

[0065] Each first-direction cutting rope 6 and each second-direction cutting rope 7 can be distinguished in color in advance and / or using marks.

[0066] Pressing the star-shaped round head 131 of the fixator 13 can be done by two people in cooperation. For example, the first person uses one hand to simultaneously hold one end of all the first-direction cutting ropes 6 in the upper layer, and the first person uses the other hand to simultaneously hold the other end of all the first-direction cutting ropes 6 in the upper layer. The second person uses one hand to simultaneously hold one end of all the second-direction cutting ropes 7 in the lower layer, and the second person uses the other hand to simultaneously hold the other end of all the second-direction cutting ropes 7 in the lower layer, so that all the first-direction cutting ropes 6 and all the second-direction cutting ropes 7 are pressed against the tumor 9.

[0067] The first person pulls the two ends of all the first-direction cutting ropes 6 back and forth to cut the tumor 9 in the first direction to a certain depth, for example, a depth of 1 - 2 cm. Then the second person pulls the two ends of all the second-direction cutting ropes 7 back and forth to cut the tumor 9 in the second direction to a certain depth, for example, a depth of 1 - 2 cm. Repeat the cutting process until the tumor 9 is finally cut into multiple square strips. The maximum width of the cross-section of the square strip should be less than the width of the second wound 16.

[0068] After cutting the tumor 9 is completed, use a clip to clamp out each square strip from the second wound 16 in sequence, and finally pull out the inner bag 3 and the outer bag 4 to complete the cutting of the tumor 9.

[0069] It should be noted that in the above method of using the surgical tumor bagging cutting device in cooperation with a rod-shaped clip, etc. to cut the tumor 9, in addition to pulling the two ends of the first-direction cutting rope 6 and the second-direction cutting rope 7 by hand, four clamps, etc. can also be used to simultaneously fix the two ends of the two groups of cutting ropes.
