Description

Technical Field

[0001] The present invention relates to the technical field of medical surgical equipment, and in particular to an integrated abdominal tumor sealing and rotary cutting device based on pneumatic control and a rotary cutting method thereof. Background Art

[0002] The research and development of intelligent medical equipment has always been a research hotspot. Many companies and scientific research institutions have achieved many successes. However, for some more mature small and medium-sized operations, the degree of intelligence is actually lower. Conversely, it will take up more human resources for simple basic work such as observation, recording, and fixation.

[0003] For example, Chinese invention patent CN215458252U discloses a laparoscopic evacuation bag. This device only enhances the airtightness of the device, but does not guarantee that the bag will not be damaged during the evacuation process, and to a certain extent, it may increase the complexity of the operation. Meanwhile, Chinese invention patent CN206630657U discloses a minimally invasive surgical specimen retrieval system with pneumoperitoneum fragmentation. Its integrated retrieval process is relatively modern, but it does not explain how to protect the bag wall from damage during violent shaking during tumor evacuation. In other words, no clamping is performed during tumor evacuation, raising questions about its safety.

[0004] Based on this, an integrated abdominal tumor closed excision equipment and excision method based on pneumatic control are proposed to solve the above problems. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides an integrated abdominal tumor closed excision equipment and excision method based on pneumatic control, which reduces the number of physicians involved in the operation while ensuring the safety of the tumor excision process and no residue remains in the body, and also reduces the number of operating holes opened in the patient's abdominal cavity.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated closed abdominal tumor removal device based on pneumatic control, comprising:

[0007] a housing, wherein a sleeve is provided at the right end of the housing;

[0008] The airbag is arranged at the right end of the sleeve, and includes a fixing ring connected to the sleeve, an air channel fixed to the fixing ring, and a bag cloth. An elastic rubber strip is fixed to the outer side of the right end opening of the airbag;

[0009] A rotatable knife tube is disposed in the housing and extends into the sleeve, wherein a rotating assembly for driving the knife tube to rotate is disposed in the housing;

[0010] An inflation assembly, disposed in the housing, for inflating the airbag;

[0011] The grasping forceps has a claw portion that can extend from one end of the shell into the sleeve and pass through the air bag to extend into the patient's abdominal cavity.

[0012] Furthermore, the outer shell is composed of a front half shell and a rear half shell, the left ends of the front half shell and the rear half shell are threadedly connected to a left cover, the right ends of the front half shell and the rear half shell are threadedly connected to a right cover, and the bottom ends of the front half shell and the rear half shell are threadedly connected to a bottom cover. This facilitates the assembly of the rotating equipment and makes it easier to install and disassemble its internal parts.

[0013] Furthermore, the right end of the sleeve is flared, and the cutout of the knife tube is arranged in the flared opening of the sleeve, which can effectively prevent the knife tube from contacting the airbag bag and causing damage to the airbag bag.

[0014] Furthermore, the rotating assembly includes a rotating sleeve that is arranged in the outer shell and can rotate, a support sleeve is fixed to the inner wall of the rotating sleeve, and the knife tube is fixed on the inner wall of the support sleeve. A rotating driving member is provided in the outer shell, and the output end of the rotating driving member is connected to the rotating sleeve through a transmission member. When the rotating driving member is started, the output end of the rotating driving member rotates, and the rotating sleeve can rotate under the transmission action of the transmission member.

[0015] Furthermore, the transmission member includes a driving bevel gear fixed to the output shaft of the rotary drive member, and a driven bevel gear meshing with the driving bevel gear is fixed to the outside of the rotating sleeve. When the output end of the rotary drive member rotates, the rotating sleeve can rotate under the meshing transmission of the driving bevel gear and the driven bevel gear.

[0016] Furthermore, a protrusion is formed outwardly on the outer circumference of the rotating sleeve, and a groove is formed inwardly on the inner wall of the shell to cooperate with the protrusion. Under the limiting action of the protrusion and the groove, the rotation of the rotating sleeve is more stable.

[0017] Furthermore, the inflation component includes an air pump arranged in the outer shell, and the air inlet pipe of the air pump passes through and extends to the bottom of the bottom cover. An abutment ring is fixed to the outside of the air inlet pipe, and a sealing ring is fixed to the bottom of the abutment ring. There is a circle of air outlet holes on the rotating sleeve, and a circle of small holes connected to the airway at the right end of the sleeve. The air pump draws external gas into the interior of the outer shell, and enters the interlayer space between the sleeve and the knife tube through the air outlet holes, and enters the airway through the small holes, and expands the bag cloth through the airway, so that the airbag bag expands and the right end opening opens, which makes it convenient for the grasping forceps to drag the tumor block from the right side opening of the airbag bag to the inside of the airbag bag, and then deflate the air through the airway to make the bag cloth shrink and wrap the tumor block.

[0018] Furthermore, the inner walls of the front half shell and the rear half shell are both provided with corresponding clips, and the housing of the rotary drive member and the housing of the air pump both form inward slots that cooperate with the clips, thereby realizing convenient disassembly and assembly of the rotary drive member and the air pump.

[0019] A method for operatively removing a peritoneal tumor using an integrated pneumatically controlled closed operative operative device, comprising the following steps:

[0020] The deflated airbag is inserted into the patient's abdominal cavity through the sleeve through the operating hole. The air pump draws outside air into the shell. The air enters the interlayer space between the sleeve and the knife tube through the air outlet hole and enters the airway through the small hole. The airbag cloth is expanded through the airway, causing the airbag to expand and the right end opening to open.

[0021] The claw part of the grasping forceps is extended from one end of the shell into the sleeve, and then extends through the air bag into the patient's abdominal cavity. The cut tumor is grabbed and dragged into the air bag. After the tumor enters the air bag, the grasping forceps drags the tumor to the incision of the knife tube. The air bag is deflated and the air bag cloth wraps the tumor.

[0022] Start the rotary drive component to rotate the output shaft of the rotary drive component. Under the meshing transmission of the active bevel gear and the driven bevel gear, the knife tube can rotate to cut the tumor. After the grasping forceps removes the cut part of the tumor from the shell, the grasping forceps are inserted into the airbag again to grab the tumor block and drag it to the incision of the knife tube. As the tumor volume decreases, the air is continuously deflated to reduce pressure. The airbag wraps the tumor again and cuts it through the rotating knife tube. This process continues until all tumors are removed from the operating port. The equipment is then removed from the surgical port for subsequent wound suturing to complete the operation.

[0023] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0024] 1. This pneumatically controlled integrated closed abdominal tumor excision equipment and method can reduce the number of medical staff required for a laparoscopic surgery. Unlike simply changing the excision bag mode to create a closed environment, this equipment can be completed independently by one person from the entire process of encapsulating the tumor to removing the airbag and residual tumor. The excision start and stop time and the airbag pressure relief point can be controlled automatically during the process, making it possible to complete more efficient and safe laparoscopic surgery with less manpower.

[0025] 2. The pneumatically controlled integrated closed abdominal tumor excision equipment and its excision method reduce the risk of tumor spread caused by debris splashing during traditional laparoscopic surgery. The device uses an airbag to wrap the tumor, and the physician uses forceps to drag the tumor into the airbag bag to achieve closed cutting of the tumor. At the same time, there are three safeguards for safety during excision. The first is that a flared structure is provided at the end of the sleeve to prevent accidental scratches on the airbag wall; the second is that the physician grasps the tumor with forceps to prevent it from shaking violently; the third is that the depressurized and contracted airbag bag wraps the tumor and clamps it in place, making it possible to improve the safety of laparoscopic surgery.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-4 In this embodiment, an integrated abdominal tumor closed excision equipment based on pneumatic control includes a shell 1, a sleeve 2 is provided at the right end of the shell 1, an airbag bag 3 is provided at the right end of the sleeve 2, a knife tube 4 extending into the sleeve 2 is provided in the shell 1, a rotating component 5 for driving the knife tube 4 to rotate is provided in the shell 1, an inflation component 6 for inflating the airbag bag 3 is provided in the shell 1, and a grasping forceps 7 can also be placed in the shell 1, the clamping part of which can extend from one end of the shell 1 into the sleeve 2 and extend through the airbag bag 3 into the patient's abdominal cavity.

[0033] The rotary cutting equipment adopts a three-layer design, with an outer protective sleeve 2 of 20mm, a middle rotary cutting knife tube 4 of 16mm, and an inner medical grasping forceps 7 of 10mm. It is compatible with the general abdominal operation hole size and can directly work with the existing standard 10mm outer diameter medical grasping forceps 7. At the same time, a pressure sensor is set inside the shell 1. The sensor captures the pressure of the air chamber in the shell 1 in real time. The pressure digital signal is compared with the normal inflation and deflation internal pressure characteristic change curve of the air chamber to formulate an inflation and deflation working mode, thereby realizing the intelligent inflation and deflation of the airbag bag 3. The intelligent design of the inflation and deflation of the airbag bag 3 and the optimization of the solution for wrapping and sealing the tumor also greatly reduce the number of auxiliary personnel and the number of operation holes.

[0034] In the initial state, the airbag bag 3 is in a contracted state. The airbag bag 3 is extended into the patient's abdominal cavity through the sleeve 2 through the operating hole, and the airbag bag 3 is inflated through the inflation component 6 to expand the airbag bag 3 to form an accommodating space. The claws of the grasping forceps 7 are then inserted into the airbag bag 3 from the shell 1, and enter the patient's abdominal cavity from the airbag bag 3 to grab the tumor and drag it into the airbag bag 3. The airbag bag 3 is then deflated, and the right opening of the airbag bag 3 is closed. At the same time, the bag cloth 33 wraps the tumor. The grasping forceps 7 moves the tumor toward the incision of the knife tube 4. The rotating component 5 drives the knife tube 4 to rotate to cut the tumor. The tumor is cut into long strips and is cut by the grasping forceps 7. The cut part of the tumor is pulled out from the shell 1 and saved for record. Then the grasping forceps 7 are inserted into the airbag bag 3, and the remaining tumor is continued to be dragged to the incision of the knife tube 4. As the tumor volume decreases, the air pressure sensor can judge and organize the next round of decompression process by itself until the tumor is wrapped and cut again. This process continues until all tumors are removed from the operation port. At this time, the doctor can take out the entire device and perform subsequent wound suture work to complete the operation. During the operation, the airbag bag 3 creates a closed cutting environment, so that the tumor block is fully cut inside it and completely removed, reducing the splashing of meat slices during cutting and returning to the patient's body to cause re-infection.

[0035] The housing 1 is composed of a front half-shell 11 and a rear half-shell 12. The left ends of the front half-shell 11 and the rear half-shell 12 are threadedly connected to a left cover 13, the right ends of the front half-shell 11 and the rear half-shell 12 are threadedly connected to a right cover 14, and the bottom ends of the front half-shell 11 and the rear half-shell 12 are threadedly connected to a bottom cover 15. The left cover 13, the right cover 14 and the bottom cover 15 are screwed together to respectively connect the left end, right end and bottom end of the front half-shell 11 and the rear half-shell 12, thereby completing the assembly of the rotating equipment and making it easier to install and disassemble its internal parts.

[0036] A sealing strip is embedded in the contact surface of the front half shell 11 and the rear half shell 12 to improve the sealing performance after the front half shell 11 and the rear half shell 12 are assembled, and sealing rings are embedded between the left cover 13, the right cover 14 and the bottom cover 15 and the outer shell 1 respectively to improve the sealing performance after the left cover 13, the right cover 14 and the bottom cover 15 are connected to the left end, right end and bottom end of the front half shell 11 and the rear half shell 12 respectively.

[0037] By setting the right end of the sleeve 2 into a flared shape and setting the cutout of the knife tube 4 in the flared shape of the sleeve 2, it is possible to effectively prevent the knife tube 4 from contacting the airbag bag 3 and causing damage to the airbag bag 3.

[0038] In this embodiment, the airbag bag 3 includes a fixing ring 31 connected to the sleeve 2. Several air channels 32 and a bag cloth 33 are provided on the fixing ring 31. By connecting the fixing ring 31 to the outer side of the right end of the sleeve 2, the bag cloth 33 can be expanded by inflating the air channel 32 to form an accommodating space.

[0039] During assembly, the fixing ring 31 can be tied to the outer periphery of the right end of the sleeve 2 with a thin rope to complete the assembly of the airbag bag 3 and the sleeve 2, and an elastic rubber strip 34 is also fixedly sleeved at the opening of the airbag bag 3, and the airway 32 stretches the bag cloth 33 to open. The elastic rubber strip 34 is stretched, the opening of the airbag bag 3 is opened, the airway 32 is exhausted, the bag cloth 33 contracts, and the elastic rubber strip 34 retracts, so that the opening of the airbag bag 3 is closed.

[0040] Since general tumor excision equipment requires auxiliary personnel to build a closed environment in the remaining operating holes, the construction process is complicated, and the tumor is only fixed by the operating physician using medical forceps 7 during the entire excision process. The tumor is prone to violent shaking, and it is easy to cause the cavity wall to rupture after hitting the closed cavity wall, causing safety hazards. However, this equipment can reduce the volume of the airbag bag 3 and perform a second wrapping of the tumor, which greatly enhances the stability and controllability of the operation and reduces the risk of damage to the wall of the airbag bag 3.

[0041] As a specific structure of a rotating assembly 5, Figure 3-4 As shown, the rotating assembly 5 includes a rotating sleeve 51 which is arranged in the outer shell 1 and can rotate. A support sleeve 52 is fixed to the inner wall of the rotating sleeve 51, and the knife tube 4 is fixed on the inner wall of the support sleeve 52. A rotating driving member 53 is arranged in the outer shell 1, and the output end of the rotating driving member 53 is connected to the rotating sleeve 51 through a transmission member.

[0042] When the knife tube 4 needs to be rotated for cutting, the rotary driving member 53 is started, and the output end of the rotary driving member 53 rotates. Under the transmission action of the transmission member, the rotating sleeve 51 can be rotated.

[0043] Among them, the transmission part includes an active bevel gear 54 fixed to the output shaft of the rotary drive part 53, and a driven bevel gear 55 engaged with the active bevel gear 54 is fixed to the outer side of the rotating sleeve 51. By starting the rotary drive part 53, the output shaft of the rotary drive part 53 rotates, and the knife tube 4 can rotate under the meshing transmission of the active bevel gear 54 and the driven bevel gear 55.

[0044] A protrusion 56 is formed outwardly on the outer periphery of the rotating sleeve 51, and a groove 57 is formed inwardly on the inner wall of the housing 1 to cooperate with the protrusion 56. Under the limiting action of the protrusion 56 and the groove 57, the rotation of the rotating sleeve 51 is more stable.

[0045] As a specific structure of an inflatable component 6, Figure 2-4 As shown, the inflation component 6 includes an air pump 61 arranged in the shell 1, and the air inlet pipe 62 of the air pump 61 passes through and extends to the bottom of the bottom cover 15. An abutment ring 63 is fixed to the outside of the air inlet pipe 62, and a sealing ring 64 is fixed to the bottom of the abutment ring 63. When the bottom cover 15 is rotated to the bottom end of the shell 1, the bottom cover 15 squeezes the sealing ring 64 to form a seal to prevent gas from leaking from the gap between the air inlet pipe 62 and the bottom cover 15. There is a circle of air outlet holes 65 on the rotating sleeve 51, and the right end of the sleeve 2 has a The airway 32 is connected to a circle of small holes 66, and the air pump 61 draws external air into the interior of the shell 1, and enters the interlayer space between the sleeve 2 and the knife tube 4 through the air outlet 65, and enters the airway 32 through the small hole 66. The bag cloth 33 is expanded through the airway 32, so that the airbag 3 is expanded and the right end opening is opened, which makes it convenient for the grasping forceps 7 to drag the tumor block from the right side opening of the airbag 3 to the inside of the airbag 3, and then the air is deflated through the airway 32, so that the bag cloth 33 is collapsed and the tumor block is wrapped, and the cutting operation can be performed.

[0046] The inner wall of the outer shell 1 forms a clamping strip 8 inwardly, and the outer shell 1 of the rotary drive component 53 and the outer shell 1 of the air pump 61 both form a clamping groove 9 inwardly. By cooperating with the clamping strip 8 and the clamping groove 9, the rotary drive component 53 and the air pump 61 are installed into the outer shell 1, thereby realizing convenient disassembly and assembly of the rotary drive component 53 and the air pump 61.

[0047] In summary, when the present invention is used, only one physician is required to perform the entire abdominal tumor rotary excision surgery. Meanwhile, the patient only needs to have two abdominal operation holes: one 20 mm operation hole for inserting the rotary excision device, and the other for inserting the medical imaging device. The specific steps of the rotary excision method of an integrated closed rotary excision device for abdominal tumors based on pneumatic control in this embodiment are as follows:

[0048] The doctor holds the outer shell 1 of the rotary cutting device in his left hand and the medical forceps 7 in his right hand, and observes the situation in the patient's abdominal cavity in real time through the imaging equipment. First, the sleeve 2 of the rotary cutting device is passed through the operating hole to extend the folded airbag 3 into the patient's abdominal cavity. The air pump 61 draws outside air into the inside of the outer shell 1. The air enters the interlayer space between the sleeve 2 and the knife tube 4 through the air outlet 65, and enters the airway 32 through the small hole 66. The bag cloth 33 is expanded through the airway 32, so that the airbag 3 is expanded and the right end opening is opened.

[0049] The claw part of the grasping forceps 7 is extended from one end of the outer shell 1 into the sleeve 2, and extends through the air bag 3 into the patient's abdominal cavity, grabbing the cut tumor and dragging it into the air bag 3. After the tumor enters the air bag 3, the grasping forceps 7 drags the tumor block to the incision of the knife tube 4, the air bag 3 is deflated, and the air bag cloth 33 wraps the tumor.

[0050] The rotary drive member 53 is started to rotate the output shaft of the rotary drive member 53. Under the meshing transmission of the active bevel gear 54 and the driven bevel gear 55, the knife tube 4 can rotate to cut the tumor. After the grasping forceps 7 remove the cut part of the tumor from the shell 1, the grasping forceps 7 are inserted into the airbag bag 3 again to grab the tumor mass and drag it to the incision of the knife tube 4. As the volume of the tumor decreases, the air is continuously deflated to reduce pressure. The airbag bag 3 wraps the tumor again and cuts it through the rotating knife tube 4. This continues until all the tumors are removed from the operation port. Until all the tumor mass is removed, the equipment is removed from the operation port and the operation is completed.
