Description

Technical Field

[0001] The invention relates to the field of laparoscopic surgical equipment, and more specifically to a laparoscopic electric hook device with a self-contained smoking function and adjustable pressure. Background Art

[0002] Laparoscopic surgery refers to making several small incisions with a diameter of 5-12mm in different parts of the abdomen. Cameras and various special surgical instruments are inserted through these small incisions. The images of various organs in the abdominal cavity taken by the camera inserted into the abdominal cavity are transmitted to the post-stage signal processing system through optical fibers and transmitted to the TV screen. The surgeon observes the images and uses various laparoscopic surgical instruments to perform operations outside the body to complete the operation.

[0003] In laparoscopic surgery, the laparoscopic electric hook is a relatively common surgical device. When using the electric hook for laparoscopic surgery, a large amount of smoke and tissue exudate will be generated. If these smoke and tissue exudate cannot be discharged from the body in time, it will have adverse effects on the surgery, such as affecting the operating field of view. In order to solve the above technical problems, some solutions have been given in the prior art. For example, the Chinese patent with the authorization announcement number CN219501147U discloses an electric hook with a suction function for laparoscopic surgery. The application sets an incomplete gear and two racks, and uses a power device to drive the incomplete gear to rotate, thereby driving the simple harmonic motion of the piston, so as to continuously suck out smoke and effusion from the patient's body, and can discharge the smoke and effusion generated when using the electric hook out of the patient's body.

[0004] However, in actual surgery, because the density of smoke is lower than that of tissue fluid, there is usually a clear stratification between smoke and tissue fluid in the body cavity. If smoke and tissue fluid exist in the body cavity at the same time, a single suction channel cannot be used to suction both smoke and tissue fluid at the same time, and thus laparoscopic surgery cannot be guaranteed to be unaffected by tissue fluid and smoke. Summary of the invention

[0005] In view of the problem in the prior art that a single suction channel cannot simultaneously suction smoke and tissue fluid, and further cannot ensure that laparoscopic surgery is not affected by tissue fluid and smoke, the purpose of the present invention is to provide a laparoscopic electric hook device with built-in suction function and adjustable pressure.

[0010] Optionally, scale lines are evenly arranged on the outer circular surface of the rod body corresponding to the position of the second magnet, so as to ensure the accuracy of adjusting the position of the abutment head.

[0011] Optionally, the rod body is also provided with a bundle tube assembly for restraining the three external suction hoses, the bundle tube assembly includes a follower ring that passes through the two electric telescopic rods and is fixedly connected to the output end of the electric telescopic rod, and the follower ring is connected to the rod body by a sliding sleeve; it also includes an intermediate ring that is fixedly connected to the outer shell of the electric telescopic rod and the rod body, and the outer circular surfaces of the intermediate ring, the follower ring and the fixed ring are all provided with three bundle tube rings in a ring shape corresponding to the mounting plate, and the three external suction hoses respectively pass through the three linearly arranged bundle tube rings and extend to the inside of the rod body to communicate with the suction channel and the external suction pipe.

[0012] Optionally, an anti-collision component is provided on the outer surface of one side of the mounting plate, and the anti-collision component includes an arc-shaped spring piece fixedly mounted on the outer surface of one side of the mounting plate, and the arc-shaped spring piece is provided with a suction hole at the position corresponding to the suction head, and a sealing sleeve is fixedly connected to the side of the arc-shaped spring piece facing the suction head, and the sealing sleeve is slidably connected to the outer cylindrical surface of the suction head.

[0019] By setting up a self-expanding and closing component, the mounting plate where the suction head is located can be automatically expanded and contracted.

[0043] like Figures 1 to 9 As shown, an embodiment of the present invention provides a laparoscope electric hook device with a self-contained smoking function and adjustable pressure, comprising a rod body 1, a hook body 2 is provided at one end of the rod body 1, and a control handle 3 is provided at the other end of the rod body 1, and a power cord 4 for power supply is provided at one end of the control handle 3; it also includes a suction channel 25 that runs through the rod body 1 and the control handle 3, and an external suction pipe 5 is fixedly connected to one end of the control handle 3 near the power cord 4, and the suction channel 25 is connected to the external suction pipe 5; a mounting cylinder 12 is provided at one end of the outer circumferential surface of the rod body 1 near the hook body 2, and the outer circumferential surface of the mounting cylinder 12 is annularly provided with three evenly distributed mounting plates 13, and a suction head 19 is provided on each of the three mounting plates 13; one end of the suction head 19 is provided with an external suction hose 9 and is connected to the suction channel 25 and the external suction pipe 5 through the external suction hose 9.

[0044] By adopting the above technical solution, when in use, the external negative pressure suction device can be connected through the external suction pipe 5, and the electric hook device can be powered on by the power cord 4. Then, when using the electric hook for laparoscopic surgery, the operator holds the control handle 3 and absorbs the tissue fluid in the body cavity during the operation through the suction channel 25 inside the rod body 1. At the same time, through three suction heads 19, and in conjunction with the external suction hose 9, the floating smoke in the body cavity is absorbed. The present application sets the suction channel 25 built into the rod body 1 in conjunction with the three suction heads 19 set outside the rod body 1, so that the tissue fluid and the floating smoke can be attracted simultaneously, and the three rings The suction head 19 arranged in a shape can better attract the floating smoke, thereby ensuring that laparoscopic surgery is not affected by tissue fluid and smoke. It should be noted here that although the external mounting plate 13, the suction head 19, and the external suction hose 9 will increase the size of the surgical incision, firstly, the mounting plate 13 can be retracted by the subsequent self-expanding and closing component to reduce the size of the surgical incision when entering the body cavity. Secondly, compared with the prior art that requires occupying another incision, placing the suction device for smoking, and requiring an assistant to assist in the smoking operation, the number of incisions can be reduced, thereby reducing harm to the patient. At the same time, there is no need for an assistant to assist in the operation, thereby improving work efficiency.

[0045] like Figure 1 , Figure 2 and Figure 5 As shown, a self-expanding and closing component that can automatically expand and contract the mounting plate 13 is provided between the mounting tube 12 and the mounting plate 13, and the self-expanding and closing component includes a fixing ring 7 fixedly connected to the outer cylindrical surface of the rod body 1 near one end of the control handle 3, and the outer surface of one side of the fixing ring 7 is symmetrically fixed to the two electric telescopic rods 24 about the rod body 1; one end of the two electric telescopic rods 24 is commonly fixedly connected to one end of the mounting tube 12, and the mounting tube 12 is connected to the rod body 1 by a sliding sleeve; the three mounting plates 13 are rotatably connected to the mounting tube 12 through a hinge, and a torsion spring 21 is also provided between the mounting plate 13 and the mounting tube 12 to ensure that the mounting plate 13 contracts toward the rod body 1 when no external force is applied, and a lifting arc 20 is provided at one end of the three mounting plates 13; a resistance opening 11 is also provided on one side of the outer cylindrical surface of the rod body 1, and a surgical depth adaptation component is provided on the rod body 1 and the position of the resistance opening 11 is adjusted by the surgical depth adaptation component.

[0046] By adopting the above technical solution, when in use, first set the position of the abutting head 11 away from the hook body 2 according to the required surgical incision depth, and then when performing laparoscopic surgery, the medical staff controls the electric telescopic rod 24 to start extending through the control handle 3, driving the mounting tube 12 fixedly connected to its output end to move, and when the lifting arc 20 does not contact the abutting head 11, due to the torsional force of the torsion spring 21, the three mounting plates 13 will retract toward the rod body 1, thereby facilitating entry into the surgical incision.

[0047] After the surgical incision is made on the lifting arc 20, the mounting plate 13 and the mounting tube 12, the lifting arc 20 begins to contact the abutting opening 11, and because the abutting opening 11 has a chamfered design, under the driving force of the electric telescopic rod 24, the three lifting arcs 20 tend to move toward the side of the abutting opening 11, and the abutting opening 11 is fixed on the rod body 1. Therefore, under the driving force of the electric telescopic rod 24, the lifting arc 20 will slide from the abutting opening 11 to the outside along the chamfer of the abutting opening 11, that is, the mounting plate 13 begins to rotate with the hinge as the axis. When the three mounting plates 13 rotate to be perpendicular to the mounting tube 12, the extension of the electric telescopic rod 24 is stopped to realize the deployment of the mounting plate 13.

[0048] The present application sets up a self-expanding and closing component, which can automatically expand and contract the mounting plate 13 where the suction head 19 is located. When contracted, the mounting plate 13 and the mounting tube 12 can enter the surgical incision with a smaller volume, thereby reducing the required incision size and reducing harm to the patient. When expanded in the patient's incision body cavity, the three suction heads 19 can be used to absorb the smoke floating in the body cavity in a more three-dimensional manner, thereby improving the suction effect of the smoke.

[0049] like Figure 8 As shown, the surgical depth adaptation component includes a No. 1 magnet 22 arranged inside the abutment head 11, and a No. 2 magnet 23 evenly arranged inside the rod body 1, and the No. 1 magnet 22 and the No. 2 magnet 23 have opposite polarities.

[0050] By adopting the above technical solution, when adjusting the position of the abutting head 11, the attraction of the No. 1 magnet 22 and the No. 2 magnet 23 can be overcome manually to move the abutting head 11. When the abutting head 11 reaches a suitable depth position, the abutting head 11 is fixed again by the attraction magnetic field of the No. 1 magnet 22 and the No. 2 magnet 23. By setting a surgical depth adaptation component, the depth of the abutting head 11 can be more conveniently adjusted according to surgical needs, and then the height of the attraction head 19 from the hook body 2 can be adjusted to meet the different depth incision conditions of different patients during laparoscopic surgery.

[0051] The outer circumferential surface of the rod body 1 is evenly provided with scale lines corresponding to the position of the second magnet 23, so as to ensure the accuracy of the position adjustment of the abutting head 11.

[0052] like Figure 1 and Figure 2As shown, the rod body 1 is also provided with a bundle tube assembly for restraining the three external suction hoses 9, and the bundle tube assembly includes a follower ring 14 that penetrates the two electric telescopic rods 24 and is fixedly connected to the output end of the electric telescopic rod 24, and the follower ring 14 is slidably connected to the rod body 1; it also includes an intermediate ring 10 that is fixedly connected to the outer shell of the electric telescopic rod 24 and the rod body 1, and the outer circumferential surfaces of the intermediate ring 10, the follower ring 14 and the fixed ring 7 are all provided with three bundle tube rings 8 in a ring shape corresponding to the mounting plate 13, and the three external suction hoses 9 respectively penetrate the three linearly arranged bundle tube rings 8 and extend to the inside of the rod body 1 to communicate with the suction channel 25 and the external suction pipe 5.

[0053] By adopting the above technical solution, using the intermediate ring 10, the follower ring 14 and the fixed ring 7 in conjunction with the tube binding ring 8 set on the outer circumferential surface, the external suction hose 9 required by the suction head 19 can be constrained to prevent different external suction hoses 9 from being entangled with each other during the operation, thereby reducing the negative pressure attraction force and affecting the surgical operation.

[0054] like Figure 3 and Figure 6 As shown, an anti-collision component 18 is provided on the outer surface of one side of the mounting plate 13, and the anti-collision component 18 includes an arc-shaped spring piece 181 fixedly installed on the outer surface of one side of the mounting plate 13, and the arc-shaped spring piece 181 is provided with a suction hole 182 at a position corresponding to the suction head 19, and a sealing sleeve 183 is fixedly connected to the side of the arc-shaped spring piece 181 facing the suction head 19, and the sealing sleeve 183 is slidably connected to the outer cylindrical surface of the suction head 19.

[0055] By adopting the above technical scheme, when the arc 20 is lifted to cooperate with the abutting head 11 to expand or retract the mounting plate 13, since the suction head 19 is directly arranged on the outer surface of the mounting plate 13, during the expansion or contraction process, the suction head 19 will be hit by the abutting head 11 and the rod body 1, which may easily damage the suction head 19. At the same time, the impact will also produce vibration, affecting the stability of the surgical operation and increasing the surgical risk. In this application, an anti-collision component 18 is provided. During the impact process, the arc-shaped spring piece 181 can convert the rigid impact of the suction head 19 into a flexible impact, and the deformation of the arc-shaped spring piece 181 is used to buffer the impact, thereby forming a protection for the suction head 19. At the same time, since the impact is buffered, the stability of the surgical operation can also be improved and the surgical risk can be reduced. In addition, the suction hole 182 and the sealing sleeve 183 on the surface of the arc-shaped spring piece 181 can ensure the normal suction function of the suction head 19, and the sliding cooperation between the sealing sleeve 183 and the suction head 19 can also ensure that the arc-shaped spring piece 181 can deform and work normally.

[0056] like Figure 2As shown, three sealing protrusions 16 are provided in an annular shape at the positions of the three suction heads 19 on the outer circumference of the rod body 1, and the sealing protrusions 16 are hemispherical rubber components. The positions of the follower ring 14 and the mounting tube 12 corresponding to the sealing protrusions 16 are penetrated by through channels 15.

[0057] By adopting the above technical solution, using the three sealing protrusions 16 on the outer circumferential surface of the rod body 1, after the surgical operation is completed and the suction head 19 is cleaned, when the electric telescopic rod 24 is retracted to drive the installation tube 12 to reset, the sealing protrusion 16 is just pushed into the suction hole 182, and the sealing protrusion 16 is tightly combined with the suction hole 182 with the torque provided by the torsion spring 21, so as to achieve the sealing and dustproof of the suction head 19. In addition, the positions of the follower ring 14 and the installation tube 12 corresponding to the sealing protrusions 16 are penetrated with a through channel 15, which can ensure that the follower ring 14 and the installation tube 12 can be driven to move normally when the electric telescopic rod 24 is retracted.

[0058] like Figure 3 and Figure 4 As shown, the mounting tube 12 is provided with a self-feedback component 17 at one end close to the abutting head 11, and the self-feedback component 17 includes an embedding groove 171 opened inside the mounting tube 12, and three arc-shaped base blocks 172 are fixedly connected in a ring shape at the middle position of the inner wall of the embedding groove 171, and the three arc-shaped base blocks 172 are all penetrated by a slidingly connected extrusion rod 175, and one end of the extrusion rod 175 is fixedly connected to an arc-shaped extrusion block 173, and a spring 174 is fixedly connected between the arc-shaped extrusion block 173 and the arc-shaped base block 172, and the spring 174 is sleeved on the outer cylindrical surface of the extrusion rod 175, and one of the extrusion rods 175 is fixedly connected to a first pole piece 176 at the other end, and a second pole piece 177 is correspondingly provided on the bottom wall of the embedding groove 171.

[0059] By adopting the above technical solution, after the arc 20 is lifted to contact the abutting head 11, as the electric telescopic rod 24 continues to extend, the mounting plate 13 will continue to rotate around the hinge. Since the component is inside the human body cavity at this time, it is not convenient to observe the expansion situation. If the electric telescopic rod 24 continues to push, it will cause the displacement of the abutting head 11, causing the depth adjustment function of the suction head 19 to fail. Therefore, by setting a self-feedback component 17, after the mounting plate 13 rotates to a position perpendicular to the mounting cylinder 12, the three arc-shaped extrusion blocks 173 are squeezed by the abutting head 11, overcome the elastic force of the spring 174 and shrink. The arc-shaped extrusion block 173 drives the extrusion rod 175 to move into the embedding groove 171. When the arc-shaped extrusion block 173 just retracts into the embedding groove 171, it drives the first pole piece 176 to just contact with the second pole piece 177 and connect the circuit, and connects the control chip in series with it to control the electric telescopic rod 24 to stop extending further. By setting a self-feedback component 17, the present application can automatically realize the control of the electric telescopic rod 24 in an environment where it is inconvenient to observe the human body cavity, thereby avoiding excessive extension of the electric telescopic rod 24 and causing the depth adjustment function of the suction head 19 to fail.

[0060] like Figure 3 As shown, the gaps between the three arc-shaped base blocks 172 and the arc-shaped extrusion blocks 173 are arranged corresponding to the through-channel 15, so that the sealing protrusion 16 can conveniently penetrate the arc-shaped base block 172 and the arc-shaped extrusion block 173 to ensure the normal operation of the device.

[0061] like Figure 1 and Figure 7 As shown, the external suction pipe 5 is provided with a suction pressure control valve 6 for adjusting the suction negative pressure. The suction pressure control valve 6 is similar to the infusion valve and is a prior art that will not be described in detail here. The negative pressure can be adjusted by a sliding roller to reduce the impact of excessive or insufficient negative pressure on the operation.

[0062] The use process of the laparoscope electric hook device provided by the present invention is as follows:

[0063] When in use, first, connect the external negative pressure suction equipment through the external suction pipe 5, use the power cord 4 to power the electric hook device, and then when using the electric hook for laparoscopic surgery, by setting the suction channel 25 built into the rod body 1 in conjunction with the three suction heads 19 set on the outside of the rod body 1, the tissue fluid and the floating smoke can be sucked simultaneously.

[0064] Then, the self-expanding and closing component can be used to automatically expand and contract the mounting plate 13 where the suction head 19 is located. When contracted, the mounting plate 13 and the mounting tube 12 can enter the surgical incision with a smaller volume, thereby reducing the required incision size and reducing harm to the patient. When expanded in the patient's incision body cavity, the three suction heads 19 can be used to absorb the smoke floating in the body cavity in a more three-dimensional manner.

[0065] When adjusting the position of the abutting head 11, the attraction of the first and second magnets 22 and 23 can be overcome manually to move the abutting head 11. When the abutting head 11 reaches a suitable depth position, the abutting head 11 is fixed again by the attraction magnetic field of the first and second magnets 22 and 23.

[0066] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0067] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
