Description

Laparoscopic surgical tools and integrated irrigation and suction laparoscopic double-acting scissors

Technical Field

The invention relates to the field of medical equipment, and in particular to a laparoscopic surgical tool and an integrated flushing and suction laparoscopic surgical double-acting scissors.

Background technique

Laparoscope is an endoscope used for intra-abdominal examination and treatment. In essence, it is applied to patients in a completely painless manner through an optical endoscope, which can directly and clearly observe the patient's intra-abdominal situation, understand the pathogenic factors, and perform surgical treatment for abnormal conditions. Laparoscopic surgery is also called "keyhole" surgery. Using laparoscopic system technology, doctors only need to open a few "keyhole"-style holes around the patient's surgical site. Without opening the abdomen, they can directly observe the patient's internal conditions in front of the computer screen and perform precise surgical operations. Compared with traditional surgery, laparoscopic surgery has small postoperative scars and meets aesthetic requirements, so patients are more willing to accept it. Minimally invasive surgery is the general trend and goal of surgical development. With the rapid development of medical instrument and equipment manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods. Coupled with the increasingly skilled operation of doctors, many past open surgeries have been replaced by intracavitary surgery, and most surgical operations can be performed with minimally invasive laparoscopic surgery. Compared with traditional surgery, the advantages of laparoscopic surgery are very obvious. First, it is less traumatic, requiring only a few small incisions less than 1 cm, and the scar is very small, which is more noteworthy for young people and women who love beauty. Second, the operation is a direct entry, which minimizes the damage to the surrounding tissues and reduces the chance of postoperative adhesion. Third, the postoperative wound pain of patients is significantly reduced. Fourth, the number of hospital stays is shorter, and some patients can be discharged from the hospital in just 2-3 days, and can fully recover and return to work in 7 days, which greatly reduces the cost burden on patients and speeds up the turnover rate of hospital beds.

During laparoscopic surgery, laparoscopic surgical scissors are very important laparoscopic surgical instruments. During laparoscopic surgery, they are mainly used to remove pathological tissues. However, traditional laparoscopic surgical scissors have relatively simple functions, only shearing functions, and do not have functions such as electrocoagulation and suction flushing. Therefore, during surgery, it is necessary to frequently replace surgical instruments, which is cumbersome to operate, takes a long time to operate, and it is difficult to improve the quality of surgery. In addition, some uncontrollable factors are prone to occur during long-term surgery. Although some existing laparoscopic scissors have functions such as electrocoagulation and removal, these functions are relatively simple and can usually only realize one function. The functions are very simple and not multifunctional. Therefore, it is also very inconvenient to use, and surgical instruments need to be frequently replaced, and the operation time is long.

Therefore, if suction and shearing can be combined together during the operation of the same laparoscopic surgical instrument, the efficiency of the operation will be greatly improved.

Compared with traditional surgery, laparoscopic surgery has small postoperative scars and meets aesthetic requirements, so patients are more willing to accept it. Minimally invasive surgery is the general trend and goal of surgical development. With the rapid development of medical instrument and equipment manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods. Coupled with the increasingly skilled operation of doctors, many open surgeries in the past have been replaced by endoscopic surgery, and most surgical operations can be performed with minimally invasive laparoscopic surgery. Compared with traditional surgery, the advantages of laparoscopic surgery are very obvious. First, the trauma is very small, only a few small incisions less than 1 cm are required, and the scar is very small, which is more noteworthy for young people and women who love beauty. Second, the operation is a single-blade entry, which minimizes the damage to the surrounding tissues and reduces the chance of postoperative adhesion. Third, the patient's postoperative wound pain is significantly reduced. Fourth, the number of hospitalization days is short, some patients can be discharged from the hospital in just 2-3 days, and they can fully recover and return to work in 7 days, which greatly reduces the cost burden on patients and accelerates the turnover rate of hospital beds.

They are very single functions and do not have multiple functions. Therefore, they are also very inconvenient to use, and surgical instruments need to be frequently replaced, and the operation time is long.

When the plug 13 is in the relaxed state, the plug 13 only extends to the snap-in groove 15 and does not contact the connecting member 20; when the plug 13 is in the tightened state, the plug 13 extends from top to bottom into the snap-in groove 15 and contacts the connecting member 20. That is, the connector 20 and the gripping member 10 are precisely fixed by the plug 13. In other words, the operator realizes the three-stage disassembly conversion of the laparoscopic surgical tool by the plug 13.

The connector 20 includes a connecting unit 21 and a first tube 22, and the first tube 22 is implemented in a cylindrical shape. The rear end of the first tube 22 is connected to the gripping member 10. The connecting unit 21 is located at the rear end of the first tube 22. The connecting unit 21 protrudes from the first tube 22. When the connector 20 is inserted into the engaging groove 15, the connecting unit 21 extends into the engaging groove 15. The connecting unit 21 is suitable for being fixed by the plug 13. That is, when the plug 13 is tightened, the plug extends from top to bottom into the engaging groove 15 and tightens the connecting unit 21. When the plug 13 is loose, the plug 13 does not contact the connecting unit 21. The first tube 22 is suitable for being engaged by a notch of the gripping member 10, and the notch extends inside to form the engaging groove 15.

In particular, the inner core member 30 includes a second tube body 31 and a scissor body 32. The scissor body 32 is located at the front end of the second tube body 31. The diameter of the second tube body 31 is smaller than the diameter of the first tube body 22. The second tube body 31 is suitable for being engaged with the inside of the first tube body 22. In other words, the first tube body 22 is suitable for wrapping the second tube body 31. When the second tube body 31 is located inside the first tube body 22, the scissor body 32 is located outside the first tube body 22. In other words, when the inner core member 30 is installed on the connector 20, the scissor body 32 protrudes from the plane where the front end surface of the first tube body 22 is located.

The scissor body 32 is suitable for shearing the patient's subcutaneous tissue to perform laparoscopic surgery. The scissor body 32 extends into the patient's body through the second tube body 31. The scissor body 32 is linked to the holding member 10. Specifically, the movable handle 11 and the fixed handle 12 move alternately with each other, driving the scissor body 32 to achieve the shearing function. In this embodiment, the scissor body 32 is implemented as a single-action scissors. That is, the shearing of the scissor body 32 is achieved by the movable handle 11. The front end of the second tube body 31 is connected to the scissor body 32, and the rear end is engaged in the engaging groove 15 to link the movable handle 11.

It is worth mentioning that the scissor body 32 includes a first scissor body 321 and a second scissor body 322. The second scissor body 322 is integrally connected to the second tube body 31. That is, the front end of the second tube body 31 is in the shape of a blade to form the second scissor body 322. The first scissor body 321 is movably arranged inside the connecting member 20. In other words, the second scissor body 322 is relatively fixedly connected to the fixed handle 12 through the connecting member 20. The first scissor body 321 is linked to the movable handle 11 from the front end to the rear end through a driving member 40.

The first scissor body 321 is movable relative to the second scissor body 322. Specifically, the first scissor body 321 is rotatably mounted on one side of the second scissor body 322 along the rear end through the driving member 40. The first scissor body 321 can rotate in an angle range of 0°-180°. While the first scissor body 321 rotates, the bottom of the first scissor body 321 contacts the top of the second scissor body 322, and the two act in an alternating manner to complete the shearing operation.

Specifically, the first scissor body 321 includes a first end face 3211, a first blade back 3212 and a first blade 3213. For the sake of convenience, the side of the first scissor body 321 close to the first blade 3213 is defined as the bottom, and the side close to the second blade back 3212 is defined as the top. Therefore, the first end face 3211 is located at the front end of the first scissor body 321, the first blade back 3212 is located at the top of the first scissor body 321, and the first blade 3213 is located at the bottom of the first scissor body 321. The first blade back 3212 and the first end face 3211 are implemented as smooth surfaces, that is, when the laparoscopic surgical tool is extended into the patient's body, blunt separation can be achieved through the first end face 3211 and the first blade back 3212. The laparoscopic surgical tool is pushed and pulled to pass through the human tissue. The first end face 3211 and the first blade back 3212 are not implemented as sharp shapes in order to prevent unnecessary scratching of the patient's subcutaneous tissue and unnecessary tissue infection during the advancement of the laparoscopic surgical tool.

The first blade 3213 rotates within a certain range within the plane where the first scissors body 321 and the second scissors body 322 intersect. The second scissors body 322 also includes a second blade 3223, and the second blade 3223 is located at the top of the second scissors body 322. The second blade 3223 is parallel to the second tube body 31. During the rotation of the first blade 3213, the shearing operation can be completed when the first blade 3213 and the second blade 3223 contact each other. In other words, since the first blade 3213 and the second blade 3223 have sharp surfaces, the two contact each other to complete the shearing. During the operation of the laparoscopic surgical tool, the first blade 3213 and the second blade 3223 achieve sharp separation of tissues.

It is worth mentioning that the scissor body 32 also has a suction channel 323, and the second scissor body 322 also includes a second end surface 3221. The second end surface 3221 is arranged at the front of the second scissor body 322. As shown in FIG4, the inlet of the suction channel 323 is arranged at the second end surface 3221. The suction channel 323 runs through the second scissor body 322 and extends backward to the gripping member 10. The suction channel 323 is suitable for sucking the accumulated fluid inside the human body.

FIG5 is a schematic diagram of the pipeline arrangement of the laparoscopic surgical tool provided by the present invention. The suction channel 323 penetrates from the second end surface 3221 of the second scissor body 322 from front to back until it extends to the gripping member 10, that is, the sucked effusion is sucked from the suction channel 323 from front to back. In other words, the suction channel 323 penetrates from the front end surface to the rear end surface of the second tube body 31. The suction channel 323 extends horizontally from the front end to the gripping member 10. The gripping member 10 also has a suction port 14, which is configured to be connected from the front end of the gripping member 10 to the top. The suction port 14 is independently spaced from the engaging groove 15. In other words, the sucked effusion does not affect the connection between the connector 20 and the gripping member 10 located in the engaging groove 15. As a result, the sucked tissue effusion is sucked from the front end to the rear end of the laparoscopic surgical tool from the suction channel 323. In other words, the sucked tissue effusion is transferred from the patient's body to the outside of the patient. The suction port 14 is the outlet of the suction channel 323 , that is, the tissue sucked by the suction channel 323 is discharged out of the patient's body from the suction port.

FIG3 is a transmission perspective view of the laparoscopic surgical tool provided by the present invention. The second tube body 31 has an inner cavity 311. The inner cavity 311 is independently separated from the suction channel 323. In other words, the inner cavity 311 and the suction channel 323 do not interfere with each other. The driving member 40 is disposed in the inner cavity 311. The front end of the driving member 40 extends to the scissor body 32, and the rear end extends to the gripping member 10.

Specifically, the driving member 40 includes a front driving unit 42, a rear driving unit 41 and a driving connecting member 43. The rear end of the front driving unit 42 is connected to the driving connecting member 43, and the rear end of the driving connecting member 43 is connected to the rear driving unit 41. That is, the front end of the driving connecting member 43 is connected to the front driving unit 42, and the rear end is connected to the rear driving unit 41. The front driving unit 42 is movably connected to the first scissor body 321. The rear driving unit 41 is movably arranged in the engaging groove 15. The rear driving unit 41 is linked to the front driving unit 42. In other words, the displacement of the rear driving unit 41 can drive the movement of the front driving unit 42. The operator can achieve the purpose of twisting the front driving unit 42 by controlling the rear driving unit 41. Further, a channel is implemented between the engaging groove 15 and the movable handle 11. When the movable handle 11 is pressably installed on the fixed handle 12, the front end of the movable handle 11 extends into the engaging groove 15 through the channel.

The operator can control the pressing of the movable handle 11 to drive the rear drive unit 41 to drive the front drive unit 42 to move through the drive connector 43, thereby driving the first scissor body 321 to move relative to the second scissor body 322 to achieve a shearing function.

The driving member 40 is implemented as a connecting rod structure in this embodiment, that is, the movement of the rear driving unit 41 at the rear end drives the movement of the front driving unit 42 at the front end. The driving connecting member 43 plays a role of connecting transmission.

Compared with the traditional instruments, the laparoscopic surgical tool in this embodiment has an additional suction channel 323 for passing a suction instrument, or directly performing negative pressure suction by utilizing the high pressure scene in the surgical patient's body. When the laparoscopic surgical tool is used to shear tissue, the vision of the shearing operation is kept clear, and it is also more convenient for the laparoscopic surgical tool to extend into the patient's body and go deep into scenes that are not easy to enter before, thereby improving the efficiency of the operation.

As shown in Fig. 6, it is a partial enlarged view of a laparoscopic surgical tool of the second preferred embodiment provided by the present invention. The laparoscopic surgical tool is different from the above embodiment mainly in the arrangement difference of a suction channel 323A and the overall structural difference.

The laparoscopic surgical tool comprises a gripping member 10A, a connecting member 20A and an inner core member 30A. The gripping member 10A is integrally connected to the connecting member 20A. The inner core member 30A is detachably mounted on the connecting member 20A. In other words, the laparoscopic surgical tool has a disassembly function. By disassembling the inner core member 30A, the inner core member 30A that has been operated and entered into the patient's body can be removed. Clean and disinfect separately. Or replace the front end with different functions according to the patient's internal condition and usage requirements.

Specifically, different from the above embodiment, the inner core member 30A includes a scissor body 32A and an inner cavity 311A, and the scissor body 32A performs different surgical functions. The scissor body 32A is detachably mounted on the front end of the connecting member 20A. In other words, the scissor body 32A can be replaced according to the specific surgical situation.

The inner cavity 311A runs through the connecting member 20A. That is, the inner cavity 311A is arranged inside the connecting member 20A to connect the front end and the rear end of the laparoscopic surgical tool. The inner cavity 311A is suitable for connecting the inside and outside of the patient's body.

The inner cavity 311A is suitable for accommodating a driving member 40 to link the holding member 10A and the inner core member 30A. Specifically, the holding member 10A includes a movable handle 11A and a fixed handle 12A and has a snap-fitting groove 15. The fixed handle 12A is integrally connected to the connecting member 20A, and the movable handle 11A is movably mounted on the rear end of the fixed handle 12A. The snap-fitting groove 15 is provided on the fixed handle 12A, and the front end of the movable handle 11A is snap-fitted to the rear end of the snap-fitting groove 15. In other words, the movable handle 11A is movably rotatable within a predetermined range with the junction of the movable handle 11A and the snap-fitting groove 15 as the axis.

In particular, the movable handle 11A can be movably engaged in the engaging groove 15, and the rear end of the driving member 40 is located in the engaging groove 15. Further, the rear end of the driving member 40 is linked to the movable handle 11A. In other words, the movement of the movable handle 11A can drive the movement of the driving member 40. Since the front end of the driving member 40 is connected to the inner core member 30A. In this embodiment, the front end lever of the driving member 40 is connected to the scissor body 32A. Therefore, the movable handle 11A can be movably connected to the scissor body 32A through the driving member 40A. In other words, the scissor body 32A is controlled by the movable handle 11A.

It is worth mentioning that the scissors 32A includes a first scissors 321A and a second scissors 322A and has a suction channel 323A. The first scissors 321A is implemented as fixed in this embodiment. That is, the first scissors 321A is vertically oriented in the horizontal direction. The second scissors 322A is implemented as movable. The second scissors 322A is movably connected to the first scissors 321A. Specifically, the second scissors 322A is movably connected to the driving member 40A. In other words, the driving member 40A drives the second scissors 322A to move. Furthermore, the movable handle 11A controls the movement of the second scissors 322A through the driving member 40A. The operator controls the second scissors 322A to perform the shearing task by controlling the movable handle 11A.

In this embodiment, the suction channel 323A is arranged on the first scissor body 321A, and the first scissor body 321A includes a first end surface 3211A, a first blade back 3212A and a first blade 3213A. The first blade back 3212A is implemented as a blunt surface, and the first blade 3213A is implemented as a sharp surface. The first end surface 3211A is located at the front end of the first scissor body 321A. In this embodiment, the inlet of the suction channel 323A is arranged on the first blade back 3212A. That is, the suction channel 323A extends backward from the first blade back 3212A to the rear end of the scissor body 32A. In addition, the suction channel 323A also runs through the connecting member 20A to extend to the gripping member 10A. The suction channel 323A is suitable for sucking the effusion in the patient's body. In other words, the operator sucks the effusion in the patient's body through the suction channel 323A.

In this embodiment, the arrangement position of the suction channel 323A is changed. Since the first blade back 3212A has a larger surface area than the first end surface 3211A, the suction channel 323A has a larger inner diameter than the previous embodiment, that is, more patient tissue fluid is allowed to pass through the suction channel 323A. A larger amount of solid impurities and the like are allowed to pass through the suction channel 323A.

As shown in Figure 8, it is a partial enlarged view of a laparoscopic surgical tool according to the third preferred embodiment of the present invention. The main difference between the laparoscopic surgical tool and the above-mentioned embodiment is that the arrangement position of the channel is changed.

The laparoscopic surgical tool comprises a gripping member 10, a connecting member 20 and an inner core member 30. The gripping member 10, the connecting member 20 and the inner core member 30 together constitute a three-section laparoscopic surgical tool. The rear end of the connecting member 20 is mounted on the gripping member 10, and the inner core member 30 is mounted inside the connecting member 20. The connecting member 20 is detachably mounted on the front end of the gripping member 10, and the inner core member 30 is inserted inside the connecting member 20.

The inner core member 30 includes a second tube body 31 and a scissor body 32. The front end of the second tube body 31 is connected to the scissor body 32, and the rear end extends to the gripping member 10. The scissor body 32 is suitable for shearing tissue in a patient's body.

The shear body 32 includes a first shear body 321 and a second shear body 322. The first shear body 321 is implemented as a fixed shear body, and the second shear body 322 is implemented as a movable shear body. The first shear body 321 and the second shear body 322 are staggered and opposite to each other to complete the shearing operation. The first shear body 321 is integrally connected to the second tube body 31, and the second shear body 322 is movably connected to the opposite side of the first shear body 321.

As shown in FIG8 , the scissor body 32 also has a suction channel 323B and a perfusion channel 324B. The first scissor body 321 is provided, and the perfusion channel 324B is provided in the second scissor body 322. The suction channel 323B is suitable for sucking tissue fluid in the patient's body, and the perfusion channel 324B is suitable for perfusing flushing fluid.

The first scissor body 321 includes a first blade 3213 and a first end face 3211, and the second scissor body 322 includes a second blade 3223 and a second end face 3221. The first blade 3213 and the second blade 3223 are implemented as sharp end faces, and the first end face 3211 and the second end face 3221 are the front end faces of the first scissor body 321 and the second scissor body 322, respectively. In particular, the inlet of the suction channel 323B is arranged on the first end face 3211 of the first scissor body 321, and the perfusion channel 324B is arranged on the second end face 3221 of the second scissor body 322.

When the laparoscopic surgical tool performs a shearing operation, the second blade 3223 slides relative to the first blade 3213. That is, when the second blade 3223 is close to the first blade 3213, shearing is completed. When the laparoscopic surgical tool performs a shearing operation, the suction channel 323B and the perfusion channel 324B also start to work. Specifically, the flushing fluid flows into the patient's body from the perfusion channel 324B and is then sucked by the suction channel 323B.

It is worth mentioning that the perfusion channel 324B is located at the second end surface 3221, and the suction channel 323B is located at the first end surface 3211. A circulation is formed between the perfusion channel 324B and the suction channel 323B to cover the front ends of the first blade 3213 and the second blade 3223 to act on the tissue in the patient to be sheared. That is to say, when the flushing liquid flows in the circulation channel from the perfusion channel 324B to the suction channel 323B, the flushing liquid can flush the tissue accumulation between the first blade 3213 and the second blade 3223, making the field of view of the lesion part to be sheared clearer, which is conducive to the operation.

As shown in Figure 9, it is a partial enlarged view of a laparoscopic surgical tool according to the fourth preferred embodiment of the present invention. The main difference between the laparoscopic surgical tool and the above-mentioned embodiment is that the arrangement position of the channel is changed.

As shown in Fig. 9, the scissor body 32 also has a suction channel 323C and a perfusion channel 324C, the inlet of the suction channel 323B is arranged on the first scissor body 321, and the perfusion channel 324B is also arranged on the first scissor body 322. The suction channel 323B is suitable for sucking tissue fluid in the patient's body, and the perfusion channel 324B is suitable for perfusing flushing fluid.

The first scissor body 321 includes a first end face 3211 and a first blade back 3212, wherein the first end face 3211 is the front end face of the first scissor body 321, and the first blade back 3212 is the blunt surface of the first scissor body 321. The inlet of the suction channel 323C is arranged at the first blade back 3212, and the perfusion channel 324C is arranged at the first end face 3211. Thus, the suction channel 323C and the perfusion channel 324C are arranged together at the first scissor body 321. The flushing liquid flows from the perfusion channel 324C to the suction channel 323C. The flow direction of the liquid is stirred during the flow process, which is conducive to flushing the part of the tissue sheared by the laparoscopic surgical tool.

As shown in Figure 10, it is a partial enlarged view of a laparoscopic surgical tool according to the fifth preferred embodiment of the present invention. The main difference between the laparoscopic surgical tool and the above-mentioned embodiment is that the arrangement position of the channel is changed.

The shear body 32 includes a first shear body 321 and a second shear body 322. The first shear body 321 is implemented as a fixed shear body. The shear body 322 is implemented as a movable shear body. The first shear body 321 and the second shear body 322 are staggered and opposite to each other to complete the shearing operation. The first shear body 321 is integrally connected to the second tube body 31, and the second shear body 322 is movably connected to the opposite side of the first shear body 321.

As shown in Fig. 10, the scissor body 32 also has a suction channel 323D, the inlet of which is arranged on the second scissor body 322, and the suction channel 323D is suitable for sucking and perfusing the tissue fluid in the patient's body. That is, the suction channel 323D is implemented as a flushing and suction integrated type.

In this embodiment, the suction channel 323D is implemented on the movable second scissor body 322 to movably flush the sheared tissue between the first scissor body 321 and the second scissor body 322. Specifically, the second scissor body 322 is linked to the gripping member 10. The operator changes the motion trajectory of the second scissor body 322 by manipulating the gripping member 10, and the flushing liquid in the suction channel 323 flows out of the patient's body and is stirred and flushed along the motion trajectory.

As shown in Figure 11, it is a partial enlarged view of a laparoscopic surgical tool according to the sixth preferred embodiment of the present invention. The main difference between the laparoscopic surgical tool and the above embodiments is that the shape of the scissors body is changed.

In this embodiment, the inner core member 30 includes a first tube body 31 and a shear body 32. The shear body 32 is located at the front end of the first tube body 31. Further, the shear body 32 includes a first shear body 321E and a second shear body 322E. The first shear body 321E is implemented as a movable end, and the second shear body 322E is implemented as a fixed end.

It is worth mentioning that the first scissor body 321E includes a first blade back 3212E and a first blade edge 3213E, and the second scissor body 322E includes a second blade back 3222E and a second blade edge 3223E. The first blade back 3212E and the second blade back 3222E are implemented as blunt surfaces. Specifically, the first blade back 3212E and the second blade back 3222E can be semicircular when viewed from the plane where the front end face is located. In other words, the scissor body 32 is implemented as the outer surface of a clamp-shaped clamp body.

As shown in FIG11 , the first blade 3213E and the second blade 3223E are implemented as sharp end faces. Compared with the above embodiment, the arrangement of the first scissor body 321E and the second scissor body 322E in the longitudinal relationship is changed from the original staggered up and down relationship to the up and down relationship. That is, the first blade 3213 is directly above the second blade 3223.

During the operation of the laparoscopic surgical tool, the first blade back 3212E and the second blade back 3222E push away the tissue in the patient's body to form a blunt separation; the first blade 3213E and the second blade 3223E abut against each other to shear the tissue to form a sharp separation.

The scissor body 321E further has a suction channel 323E, the inlet of which is arranged at the front end surface of the first scissor body 321E, and extends backward from the front end surface of the first scissor body 321E and penetrates the whole body.

As shown in Figure 12, it is a partial enlarged view of a laparoscopic surgical tool according to the seventh preferred embodiment of the present invention. The main difference between the laparoscopic surgical tool and the above-mentioned embodiment is that the material of the scissors body is changed.

In this embodiment, the inner core member 30 includes a first tube body 31 and a shear body 32. The shear body 32 is located at the front end of the first tube body 31. Further, the shear body 32 includes a first shear body 321F and a second shear body 322F. The first shear body 321F is implemented as a movable end, and the second shear body 322F is implemented as a fixed end.

The first scissors 321F and the second scissors 322F can be used for electrocoagulation hemostasis and electrocautery. That is, the front ends of the first scissors 321F and the second scissors 322F can be conductive. In other words, the rear end of the laparoscopic surgical tool can be extended to the front end to conduct electricity, so as to perform electrocoagulation hemostasis, electrocautery, and other operations.

As shown in FIG12 , a conductive unit 50F is disposed at the junction of the first scissor body 321F and the second scissor body 322F. Specifically, the conductive unit 50F is disposed on a first blade 3213F of the first scissor body 321F. When the first blade 3213F approaches the second scissor body 322F, the conductive unit 50F operates to perform electrocoagulation hemostasis, electrocuting and other operations to separate the patient's tissues.

Embodiment 1:

13 to 16 , the flushing and suction integrated double-acting scissors for laparoscopic surgery according to a preferred embodiment of the present invention are schematically shown.

The integrated flushing and suction laparoscopic surgical double-action scissors 91 are used for laparoscopic surgical operations and for cutting human tissues. When cutting human tissues, the effusion and blood produced by the intra-abdominal tissues can be flushed and sucked at the same time, thereby maintaining a clear field of vision during the operation and ensuring that the operator can complete the operation with a clear field of vision.

In detail, the integrated flushing and suction laparoscopic double-action scissors 91 may include a first blade head 910, a second blade head 920, a control handle 930 and a shaft 940, wherein the first blade head 910 and the second blade head 920 are pivotally connected to one end of the shaft 940, and the control handle 930 is connected to the second blade head 920. The handle 930 is mounted on the other end of the shaft 940 .

The first blade head 910 has a fluid outlet 911 and a fluid outflow channel 912. The fluid outlet 911 is connected to one end of the fluid outflow channel 912. The fluid outflow channel 912 is arranged along the axis of the first blade head 910, that is, from the control handle 930 toward the shaft 940. The fluid outflow channel 912 is arranged inside the first blade head 910, that is, the fluid outflow channel 912 is formed inside the first blade head 910.

The first cutting head 910 also includes a first front end wall 913 and a first top wall 914. The first front end wall 913 is located at the front end of the first cutting head 910, that is, the end away from the control handle 930. The first top wall 914 is connected to the first front end wall 913, and the plane of the first top wall 914 is parallel to the axis of the fluid outflow channel 912.

Those skilled in the art should understand that the axis of the fluid outflow channel 912 may not be parallel to the plane where the first top wall 914 is located.

The fluid outlet 911 is provided on the first front end wall 913, and in particular, the cross section of the first front end wall 913 is conical, and the sharp end of the conical shape is used for sharp cutting, and the non-sharp end can be provided with the fluid outlet 911 due to its larger area, thereby completing the integrated arrangement of the fluid outlet 911 and the fluid outflow channel 912. Such an arrangement makes the structure of the first blade head 910 more compact, that is, the first blade head 910 can still maintain a small volume after the fluid outflow channel 912 is provided, thereby minimizing the opening diameter in the patient's abdomen as much as possible during laparoscopic surgery.

It is worth mentioning that the non-sharp end of the first front end wall 913 has a sufficient width, that is, it is blunt, and can be used for blunt separation during surgery, and can be used as a tool to open patient tissue during surgery.

The first front end wall 913 is smoothly connected to the first top wall 914, so that when the first blade head 910 enters the abdominal cavity, the first blade head 910 contacts the patient's tissue smoothly without damaging the patient's normal tissue, and it is also more convenient for the first blade head 910 to perform blunt separation.

The first blade head 910 also has a top wall fluid outlet 915, which is disposed on the upper side of the first top wall 914 and close to the first front end wall 913.
