Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a dry cell portable electric knife under field conditions. Background Art

[0002] High-frequency electrosurgical unit has been used in clinic for more than 70 years since 1920. It has gone through four generations of changes from spark plug discharge to high-power electron tube to high-power transistor to high-power MOS tube. With the popularization, application and development of computer technology, automatic adjustment of power waveform, voltage and current under various functions, detection of various safety indicators, programmed control and fault detection and indication have been implemented. Therefore, the safety and reliability of the equipment itself have been greatly improved, and the operation process of doctors has been simplified.

[0003] At the same time, with the development of medical technology and the requirements of clinical practice, composite electrosurgical equipment based on high-frequency surgical instruments has also developed accordingly: high-frequency argon gas knife, high-frequency ultrasonic surgical system, high-frequency electrosurgical endoscope treatment system, high-frequency rotary cutting fat removal machine and other equipment have achieved remarkable results in clinical practice. And the various special accessories for high-frequency surgical instruments derived from it (such as bipolar electric shears, bipolar electrosurgical mirrors, electrosurgical mirror vaporization roller electrodes, etc.) have also opened up a wider range of applications for clinical surgery. High-frequency electrosurgical knives use the thermal effect of high-frequency electricity to denature and break tissue proteins and separate them, and high-frequency current will not cause spasms and other electric shock effects on organisms. Compared with scalpels, it has the advantages of hemostasis, disinfection, clear vision, and fast wound healing during cutting, so it has been widely used in modern medicine. At present, the power supply of high-frequency electrosurgical knives is provided by AC mains in the operating room, so it is not convenient for users to use it in field conditions, such as emergency rescue for disaster relief, single-soldier combat, etc., so the scope of use is greatly limited. Therefore, dry battery-type electrosurgical knives used in field conditions have appeared.

[0004] However, there are still some defects and shortcomings in the use of dry-cell battery-powered electric knives in field conditions. The specific areas that need to be improved are as follows:

[0005] 1. The existing dry-cell electric knife used in the field cannot assist the staff to replace the dry-cell, that is, it cannot quickly replace the dry-cell that runs out of power during the field treatment in an emergency situation to reduce the impact of the dry-cell power shortage in the field emergency treatment situation, thus increasing the probability of the injured person's injury getting worse;

[0006] 2. Existing dry-cell battery-powered electric knives used in the field cannot assist users in carrying the knife stably, that is, it is not convenient for users to protect the knife while carrying it, thereby increasing the probability of damage to the knife during outdoor activities.

[0007] 3. The dry-cell battery-powered electric knife used in the field cannot converge the line, that is, it cannot reset the electric knife and the line after the user finishes using the electric knife to reduce the time it takes to converge the electric knife and the line after the user finishes using it, which brings certain difficulties to the user's stop-and-go use in complex field conditions.

[0008] 4. The existing dry-cell battery-powered electric knife used in the field cannot be cleaned after use, that is, the dirt on the electric knife cannot be cleaned after the user uses it to facilitate the user's use in the next treatment, which brings certain inconveniences to the user in reusing the electric knife in the field.

[0009] 5. The existing dry-cell battery-operated electrosurgical units used in the field cannot facilitate users to control the extension length of the line, that is, they cannot maintain an appropriate line length during medical treatment using the electrosurgical unit to avoid the user's use of the electrosurgical unit for treatment being affected by the line being too short or too long, thereby increasing the probability of medical errors caused by line obstruction during treatment using the electrosurgical unit in complex outdoor conditions.

[0024] (III) Beneficial effects

[0025] The beneficial effects of the present invention are:

[0026] 1. The dry-cell portable electric knife under field conditions rotates around the fixed connecting nail by pulling the two pulling rotating arms through the pulling column. The torsional force of the two first reset torsion springs will be overcome during the rotation of the two pulling rotating arms. The two power sliding columns will have a tendency to move left and right through the two matching guide grooves. In this process, the two power sliding columns will move to the left through the restrictions of the linkage plate, the driven column and the auxiliary sliding groove, and then the concave frame can be driven to move to the left synchronously. During the movement of the concave frame to the left, the limiting sliding groove and the limiting sliding bar will be used for guidance and restriction, so that multiple dry batteries in the concave frame can move. During the replacement process, the dry battery that has finished consuming power will be pushed to separate from the storage shell and fall off. At the same time, the new dry battery will be connected to the energized elastic sheet to power the electric knife main body to assist the user. After the replacement is completed, it can be reset by the torsional force of the two first reset torsion springs, thereby further stabilizing, restricting and protecting the replaced dry battery, thereby solving the problem that the existing dry battery-type electric knife used in the field conditions cannot assist the staff to replace the dry battery, that is, it is impossible to quickly replace the dry battery that lacks power during the field treatment in an emergency situation, so as to reduce the impact of the dry battery shortage in the field emergency treatment situation, thereby increasing the probability of the injured person's injury worsening.

[0027] 2. In the field, the portable electric knife with dry batteries can reduce the shock of the sleeve tube by the elastic material of the four restraints and the first Velcro, so as to reduce the shock of the main body of the electric knife. When the user falls and lands on his chest, the four rolling wheels will first contact the ground. After the four rolling wheels contact the ground, they will drive the corresponding ends of the four shock-absorbing arms to expand synchronously. Even if the four shock-absorbing arms rotate about the center of a circle under the support of the four connecting hinges and the four fixed connecting shafts, they will also cooperate with the four reset turntables and the four second reset torsion springs to perform auxiliary reset during the rotation process, so as to protect the sleeve tube and the main body of the electric knife. In this process, the four auxiliary arms will be driven to extend outside the shock-absorbing slide groove, and the four shock-absorbing sliders will be driven to move in the four shock-absorbing slide grooves during the extension process. Inward sliding, during the sliding process of the four shock-absorbing slide grooves, four groups of limiting slide columns will be used for auxiliary guidance. During the sliding process, the elastic force of the four groups of corresponding shock-absorbing springs will be overcome, thereby further increasing the difficulty of deploying the four groups of shock-absorbing arms, and multiple shock-absorbing springs and multiple second return torsion springs will be used for shock reduction, thereby protecting the user from falling, and at the same time protecting the electric knife body. The electric knife body will also achieve the purpose of high-quality protection by being carried on the user's chest, thereby solving the problem that the existing dry-cell battery-powered electric knife used in the field cannot assist the user to carry it stably, that is, it cannot be convenient for the user to protect the electric knife during the carrying process, thereby increasing the probability of damage to the electric knife during the user's outdoor exercise.

[0028] 3. The portable electric knife with dry cells in outdoor conditions is convenient for the user to insert the electric knife head with one hand by providing a protective shell. During the insertion process, the elastic layer will be used for protection and restriction, and the transmission line will be pushed through the protective tube and discharged to the outside of the suction tube, and then the connecting tube will be squeezed to pop out so that the suction plug head slides in the suction tube to overcome the elastic force of the pop-up spring for reset. At the same time, the pulling of the control connecting rope can be loosened to cooperate with the tightening spring to reset the guide slide board, and then the magnetic suction strip is reset and connected to the magnetic suction cup to restrict the pop-up spring, so that the user can control the electric knife head to pop out for use next time. After the electric knife head is restricted in the protective shell, the protective shell and the connecting line can be used to protect the electric knife head, thereby solving the problem that the existing dry cell electric knife used in the field cannot converge the line, that is, the electric knife and the line cannot be reset after the user finishes using the electric knife, so as to reduce the time for converging the electric knife and the line after the user finishes using it, thereby bringing certain difficulties to the user's stop-and-go use in complex outdoor conditions.

[0029] 4. The portable dry-cell battery-operated electric knife for outdoor use, by setting the suction plug to slide forward in the suction cylinder, and cooperating with one-way valve 1, one-way valve 2 and the suction pipe to suck the clean water stored in the connection box, the suction plug slides backward in the suction cylinder to squeeze the clean water in the suction cylinder, and at the same time cooperates with one-way valve 1 and one-way valve 2 to send the clean water from the two water outlet pipes into the flushing spray rack, and then the electric knife head can be sprayed out through the nozzle arranged on the inner wall of the flushing spray rack to clean it, so as to facilitate the subsequent convenient use by the user, and also prevent the infection of the electric knife head to the patient during the use of the electric knife head, thereby solving the problem that the existing dry-cell battery-operated electric knife used in the field cannot perform auxiliary cleaning on the electric knife after use, that is, it cannot clean the dirt on the electric knife after the user uses the electric knife, so as to facilitate the user's use at the next treatment, thereby causing certain inconvenience to the user in repeatedly using the electric knife in the field.

[0030] 5. In the field, the dry-cell portable electric knife can move the finger cover through the corresponding finger movement, and the finger cover will pull the control rope to move. During the movement of the control rope, the elastic force of the tension spring will be overcome to drive the guide slide to move. During the movement of the guide slide, the two guide slide grooves on the control frame will be used for limiting and guiding. During the movement of the guide slide, the magnetic suction strip will be synchronously driven to separate from the magnetic suction disk and the suction cylinder, and then the pop-up spring will release the restriction, and then the pop-up spring will pull the suction plug to slide quickly in the suction cylinder, and then drive the pop-up connecting cylinder to synchronously and quickly push the electric knife head out of the protective shell to the palm of the user. When the electric knife head is discharged from the protective shell, it will drive the transmission line to pass through the sealed cylinder and then pass through the main body of the electric knife. The switch will start the electrosurgical unit, and after the electrosurgical unit is started, power will be supplied to the electrosurgical unit head through the connecting couple and the transmission line. Then the user can hold the electrosurgical unit head to perform surgery on the patient. During this process, the transmission line will be restricted by the sealed penetration tube, making it easier for the user to hold the unit for surgery and avoiding the transmission line affecting the user's surgical operation process. This solves the problem that the existing dry-cell battery-powered electrosurgical units used in the field cannot facilitate the user to control the line extension length, that is, cannot maintain an appropriate line length during the use of the electrosurgical unit for medical treatment, so as to avoid the user's use of the electrosurgical unit for treatment being affected by a line that is too short or too long, thereby increasing the probability of medical errors caused by line obstruction during the user's use of the electrosurgical unit for treatment in complex field conditions.

[0057] The operating steps of the present invention are:

[0058] When the electric knife body 3 and the electric knife head 62 need to be carried for use outdoors, the electric knife body 3 is first tied to the user's chest through four tie straps 210 and the corresponding first Velcro 211 in conjunction with the sleeve 21, and the electric knife head 62 is tied to the user's hand position through four arm straps 51 and the second Velcro 52, and the finger sleeve 76 is sleeved on the user's finger for easy movement. During the sleeve process, the flexible anti-slip layer maintains the comfort and stability of wearing;

[0059] If vibration occurs during the carrying process, the elastic material of the four restraint belts 210 and the first Velcro 211 will cooperate to damp the shock of the sleeve tube 21, and the electrosurgical unit 3 can be damped. When the user falls and lands on his chest, the four rolling wheels 23 will first contact the ground. After the four rolling wheels 23 contact the ground, they will drive the corresponding ends of the four shock-absorbing arms 22 to unfold synchronously. Even if the four shock-absorbing arms 22 rotate about the center of a circle under the support of the four connecting hinges 29 and the four fixed shafts 214, they will also cooperate with the four reset turntables 213 and the four second reset torsion springs 212 to perform auxiliary reset during the rotation process, thereby protecting the sleeve tube 21 and the electrosurgical unit 3. In this process, the four groups of auxiliary arms 24 will be driven to extend out of the shock-absorbing slide grooves 25. During the extension process, the four shock-absorbing sliders 26 will be driven to slide in the four shock-absorbing slide grooves 25. During the sliding process of the four shock-absorbing sliders 26, four groups of limiting slide columns 28 will be used for auxiliary guidance. During the sliding process, the elastic force of the four groups of corresponding shock-absorbing springs 27 will be overcome, thereby further increasing the difficulty of unfolding the four groups of shock-absorbing arms 22. In addition, multiple shock-absorbing springs 27 and multiple second return torsion springs 212 will be used for shock absorption, thereby protecting the user from falling. At the same time, the electrosurgical unit 3 will also be protected. The electrosurgical unit 3 will also achieve the purpose of high-quality protection by being carried on the chest of the user.

[0060] When the electrosurgical knife body 3 needs to be used, the user first moves the finger sleeve 76 through the corresponding finger movement. After the finger sleeve 76 moves, it will pull the control rope 75 to move. During the movement of the control rope 75, the elastic force of the tensioning spring 74 will be overcome to drive the guide slide 77 to move. During the movement of the guide slide 77, it will be restricted and guided by the two guide grooves 73 provided on the control frame 72. During the movement of the guide slide 77, the magnetic suction strip 71 will be synchronously driven to separate from the magnetic suction disk 68 and the suction cylinder 63, and then the pop-up spring 66 will release the restriction, and then the pop-up spring 66 will pull the suction plug 65 to slide quickly in the suction cylinder 63, and then the suction plug 65 will be pulled out of the suction cylinder 63. The ejection connecting tube 67 will be driven to synchronously and quickly push the electric knife head 62 out of the protective shell 56 to the palm of the user. When the electric knife head 62 is discharged from the protective shell 56, the transmission line 42 will be driven to pass through the sealed through tube 64. Then, the electric knife body 3 will be operated through the switch on the electric knife body 3. After the electric knife body 3 is operated, the electric knife head 62 will be powered through the connecting couple and the transmission line 42. Then, the user can hold the electric knife head 62 to perform surgery on the patient. During this process, the transmission line 42 will be restricted by the sealed through tube 64, so that the user can hold the electric knife head 62 to perform surgery and avoid the transmission line 42 affecting the user's surgery process.

[0061] After use, the electric knife head 62 can be inserted into the protective shell 56 again. During the insertion process, it will be protected and restricted by the elastic layer 58, and at the same time, the transmission line 42 will be pushed through the protective tube to be discharged to the outside of the suction tube 63, and then the ejection connecting tube 67 will be squeezed to make the suction plug 65 slide in the suction tube 63 to overcome the elastic force of the ejection spring 66 for reset. At the same time, the pulling of the control connecting rope 75 can be released to cooperate with the tightening spring 74 to reset the guide slide plate 77, and then the magnetic suction strip 71 can be reset and connected to the magnetic suction cup 68 to restrict the ejection spring 66. After that, it is convenient for the user to control the electric knife head 62 to be ejected for use next time. After the electric knife head 62 is restricted in the protective shell 56, the electric knife head 62 can be protected by the protective shell 56 and the connecting line.

[0062] When the ejection connecting tube 67 pushes the electric knife head 62 to be discharged outwards for the user to hold and use, the sliding of the suction plug 65 in the suction cylinder 63 will cooperate with the one-way valve 1 83, the one-way valve 2 84 and the suction pipe 85 to suck the clean water stored in the connection box 53. When the electric knife head 62 is squeezed and reset, the sliding of the suction plug 65 in the suction cylinder 63 will squeeze the clean water in the suction cylinder 63, and cooperate with the one-way valve 1 83 and the one-way valve 2 84 to send the clean water from the two water outlet pipes 82 into the flushing spray rack 81, and then the electric knife head 62 can be sprayed out through the nozzle arranged on the inner wall of the flushing spray rack 81 to clean the electric knife head 62, so as to facilitate the user's subsequent convenient use, and also prevent the dirt from causing infection to the patient during the use of the electric knife head 62;

[0063] When the battery needs to be replaced urgently during use, the concave frame 114 can be pushed to slide, thereby pushing the dry battery 111 set in the concave frame 114 to move, and then the new dry battery 111 can be moved to the energized elastic sheet 112 to achieve the purpose of replacement. The dry battery 111 that has finished consuming power will cooperate with the movement of the concave frame 114, and separate from the storage shell 12 to discharge the dry battery 111 that has finished consuming power to the ground, thereby completing the replacement operation of the dry battery 111; the two pulling rotating arms 15 can also be pulled by the pulling column 18 to rotate around the fixed connecting nail 13 as the center. During the rotation of the two pulling rotating arms 15, the torsional force of the two first reset torsion springs 110 will be overcome. During the rotation of the two pulling rotating arms 15, the two power sliding columns 16 will have a tendency to move left and right through the two matching guide grooves 14. During this process, the concave frame 114 can be driven to move to the left side by the restriction of the linkage plate 17, the driven column 19 and the auxiliary slide groove 11, and then the concave frame 114 can be driven to move to the left side synchronously. During the movement of the concave frame 114 to the left, the restriction slide groove 113 and the restriction slide bar 215 can be used to guide and restrict the multiple dry batteries 111 in the concave frame 114, and the dry batteries 111 that have finished consuming power can be pushed to separate and fall from the storage shell 12 during the movement. At the same time, the new dry batteries 111 can be connected to the energized elastic sheet 112 to power the electric knife body 3 to assist the user. After the replacement is completed, the two first reset torsion springs 110 can be used to reset the replaced dry batteries 111, and the replaced dry batteries 111 can be further stabilized, restricted and protected, thereby completing the efficient replacement operation of the dry batteries 111.

[0064] After the emergency use of the electrosurgical unit 3 is over, a new dry cell battery 111 can be inserted into the storage shell 12 through the insertion slot 115 for storage. In this process, the elastic rubber material limitation of the two elastic limiting walls 116 will be overcome. At the same time, the elastic limiting walls 116 will also be used to limit the insertion of the dry cell battery 111 from falling, thereby facilitating the replacement of the dry cell battery 111 in the next emergency situation.

It should be understood that the above are only specific implementation methods of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
