Thus, when the tissue is cut and hemostasis is carried out, after the electrode seat 11 is powered, an operator holds the two forceps handles 12 and closes the forceps handles, so that the two forceps tips 13 can cut and hemostasis is carried out on the tissue; when the nerve is required to be stimulated and detected, an operator can continuously hold the forceps handle 12, only the push button 24 is pushed to enable the head end of the probe 23 to protrude out of the forceps tip 13, and the nerve detection instrument is started to detect the nerve, so that the nerve cannot be damaged by using the special probe 23; meanwhile, the surgical instrument does not need to be replaced, and the parts for cutting hemostasis and nerve detection belong to different working ends, so that interference and influence can not be generated between the parts.
Furthermore, because the nerve detection module is detachably arranged on the forceps handle 12 through the mounting seat 21, after the operation is finished, the nerve detection module with higher cost can be taken down and can be reused after the disinfection treatment, and the electric coagulation forceps module can be abandoned after the disinfection treatment according to the disposable medical instrument use standard, so that the manufacturing cost and the use cost of the bipolar electric coagulation forceps with the nerve detection function and the cutting hemostasis function are greatly reduced, the function is well used, the economic effect is obvious, and the electric coagulation forceps are more suitable for market popularization.
Considering that in the actual use process, when the operator needs to switch to the nerve detection module after using the electric coagulation forceps module, as the operator holds the electric coagulation forceps module and clamps the two forceps handles 12 by the palm tiger mouth, when the push button 24 is stirred, the operator tiger mouth naturally contracts inwards to form extrusion on the two forceps handles 12, namely when the electric coagulation forceps is switched to the nerve detection module, the operator can easily mistakenly touch to cause the two forceps tips 13 to be clamped so as to generate high heat, and the operation potential safety hazard exists.
In view of this, referring to fig. 4 and 5, the application further provides that the forceps handle 12 provided with the mounting seat 21 is provided with a through hole 16 penetrating through the forceps handle 12 and the alignment seat 14 or the alignment head 15, the mounting seat 21 is internally provided with a countering pin 17 in insertion fit with the through hole 16, and the countering pin 17 is fixedly connected with an anti-falling piece 18 for preventing the countering pin 17 from falling out of the mounting seat 21; the anti-falling piece 18 is arranged as an anti-falling piece fixedly connected to one end of the offset 17 close to the probe 23, and the size of the anti-falling piece is larger than that of the through hole 16.
Referring to fig. 4 and 5, the mounting base 21 is provided with an anti-false touch mechanism for pushing out the offset 17 to the outside of one end of the through hole 16 between the two forceps handles 12 when the push button 24 is rotated or when the push button 24 is slid to approach the forceps tips 13; specifically, the anti-false touch mechanism includes a collar 31 sleeved on the probe 23 in a same way and a protrusion 32 fixedly connected to an outer arc surface of the collar 31, wherein the protrusion 32 is arranged in a fan shape around the periphery of the collar 31 but does not completely surround the collar 31 and forms a notch at an un-surrounding position, and the size of one side of the notch close to the collar 31 is smaller than the size of the offset 17 so as to prevent the offset 17 from being pushed out when the collar 31 is rotated; limiting sheets 33 are fixedly connected in the mounting seat 21 and positioned on two sides of the lantern ring 31, and when the push button 24 rotates until the convex portions 32 are aligned with the offset 17, the offset 17 is pushed out and protrudes out of the through hole 16.
In other possible embodiments, in order to avoid that the offset 17 protrudes too far into the opening 311, referring to fig. 6 and 7, a blocking piece 19 located on the side of the anti-falling member 18 near the probe 23 may be fixedly connected in the mounting seat 21. When the offset 17 moves into the notch of the insertion protrusion 32 and abuts against it, the retaining piece 18 abuts against the blocking piece 19. By providing the retaining member 18 and the blocking piece 19 in this way, the vertical stroke of the cancellation member 17 can be restricted to ensure the optimal control effect.
Therefore, when the probe 23 needs to be extended, the push button 24 is rotated, the push button 24 drives the probe 23 and the lantern ring 31 connected with the probe 23 in a co-action manner to rotate until the convex part 32 rotates to push the offset 17 out of the through hole 16, and the offset 17 limits the two forceps handles 12 at the moment, so that the two forceps tips 13 cannot be closed; and then pushing the push button 24 to extend the probe 23, in the process, as the lantern ring 31 is sleeved on the probe 23 in a same way, and the two limiting sheets 33 limit the lantern ring 31, the convex part 32 on the lantern ring 31 always keeps the pushing effect on the offset 17 when the probe 23 slides, so that when the probe is switched to a nerve detection module, the two forceps handles 12 cannot be closed, and the hidden danger of mistakenly touching the forceps handles 12 can not be generated.
Considering the actual assembly convenience and assembly efficiency of the nerve detection module, so as to control the production cost, referring to fig. 5 and 6, the mounting seat 21 is set to be a lower seat 212 detachably mounted on the forceps handle 12 and an upper cover 211 detachably mounted on the lower seat 212, a section of flat part 231 is arranged in the middle of the probe 23, a gap 311 which is in plug-in fit with the flat part 231 is formed in the collar 31, the flat part 231 is embedded in the gap 311, and an anti-falling structure for preventing the collar 31 which rotates along with the probe 23 from falling off from the probe 23 is arranged in the mounting seat 21. When the anti-falling structure is specifically arranged, the anti-falling structure can be arranged as an anti-falling cavity 213 integrally formed on the upper cover 211, the anti-falling cavity 213 is arranged as an arc cavity, and the central axis of the anti-falling cavity 213 and the probe 23 are coaxially arranged; when the upper cover 211 and the lower base 212 are assembled, the collar 31 and the protrusion 32 are inserted into the anti-drop cavity 213, and the collar 31 and the protrusion 32 thereon can rotate in the anti-drop cavity 213 with the axis of the probe 23 as the rotation axis, but cannot move in a direction away from the lower base 212 due to the limitation of the anti-drop cavity 213.
And in order to make the push button 24 smoother when the probe 23 is rotated, referring to fig. 5, the convex portion 32 is provided with a first transition surface 34 along a circumferential side wall of the collar 31, and/or the offset 17 is provided with a second transition surface 35 near one end of the probe 23. In the embodiment of the present application, the convex portion 32 and the offset 17 are respectively provided with a first transition surface 34 and a second transition surface 35.
In summary, there are two modes of operation when the electric coagulation forceps module is in use, the first mode is to push the push button 24 directly along the long groove 261 without rotating the push button 24, at this time, the notch on the convex portion 32 is aligned with the offset 17, when the probe 23 is pushed, the offset 17 does not have an anti-false effect on the two forceps handles 12, and this mode has a great potential safety hazard when the electrode holder 11 is kept continuously energized. In the second mode, the push button 24 is rotated firstly, the convex part 32 on the lantern ring 31 is rotated until the offset 17 is pushed out of the through hole 16, and then the push button 24 is pushed until the probe 23 is pushed out, and in the mode, even if the electrode holder 11 is kept electrified, the two forceps tips 13 cannot be closed; however, when performing nerve detection, the probe 23 extending to the set position may still retract into the mount 21, which may cause inconvenience to the nerve detection operation.
Therefore, in a further arrangement, referring to fig. 2, the mounting seat 21 is provided with a locking groove 262 jogged and matched with the push button 24 on the groove wall of one end of the long groove 261 close to the forceps tip 13; when the push button 24 is rotated into engagement with the locking groove 262, the probe 23 protrudes beyond the forceps tip 13 and the boss 32 abuts against the offset 17. Thus, when the push button 24 is pushed into the locking groove 262, the push button 24 is limited by the locking groove 262, and the probe 23 cannot retract into the mounting seat 21 independently, so that an operator does not need to push the push button 24 all the time, and the convenience of the electric coagulation forceps in use is improved.
Meanwhile, in order to reduce the inconvenience caused by frequently opening and closing the nerve detector in the operation process, a switching-on mechanism is arranged between the push button 24 and the detection lead 25, and the push button 24 is switched on with the detection lead 25 through the switching-on mechanism only when the probe 23 is pushed to the convex forceps tip 13; specifically, referring to fig. 6, the switch-on mechanism includes a metal contact strip 51 electrically connected to the detection wire 25, and a metal contact block 52 electrically connected to the probe 23 is fixedly connected to the push button 24 or the probe 23; when the probe 23 is pushed to the protruding forceps tip 13, the metal contact block 52 collides with the metal contact bar 51.
Therefore, before the probe 23 does not move in place, the probe 23 and the nerve detector are in an open circuit state, and when the probe 23 is pushed in place, the metal contact block 52 is in conflict with the metal contact strip 51, and the nerve detection can be carried out by the electrifying method of the probe 23.
In order to facilitate the disassembly and assembly of the nerve detection module and the electric coagulation forceps module, referring to fig. 2 and 3, a plurality of buckles 6 are fixedly connected on the mounting seat 21, the inclined table at the free end of each buckle 6 is arranged in a direction of the axis of the probe 23, and the mounting seat 21 is buckled on the forceps handles 12 through the buckles 6; alternatively, in other possible embodiments, the lower base 212 may be mounted on the forceps handle 12 by screwing, magnetic attraction, or the like, with only the forceps handle 12 being adapted. In consideration of cost factors in actual production, the scheme of modifying the electric coagulation forceps module to the minimum is adopted in the embodiment, so that the nerve detection module is suitable for electric coagulation forceps of most models.
Thus, the mounting seat 21 is buckled on the forceps handle 12 through the buckle 6, so that the convenience and the detachability of the nerve detection module are realized, the disposable electric coagulation forceps module can be directly abandoned after the operation is finished, the nerve detection module is mounted on the forceps handle 12 of the new electric coagulation forceps module, the reuse of the nerve detection module can be realized, and the operation cost is effectively controlled.
The bipolar electric coagulation forceps with the nerve detection function provided by the embodiment of the application has the implementation principle that: when the tissue is cut and hemostasis is carried out, after the electrode seat 11 is powered, an operator holds the two forceps handles 12 and closes the forceps handles, so that the two forceps tips 13 can cut and hemostasis is carried out on the tissue; when the nerve is required to be stimulated and detected, an operator can continuously hold the forceps handle 12, only the push button 24 is pushed to enable the head end of the probe 23 to protrude out of the forceps tip 13, and the nerve detection instrument is started to detect the nerve, so that the nerve cannot be damaged by using the special probe 23; meanwhile, the surgical instrument does not need to be replaced, and the parts for cutting hemostasis and nerve detection belong to different working ends, so that interference and influence can not be generated between the parts.
Furthermore, because the nerve detection module is detachably arranged on the forceps handle 12 through the mounting seat 21, after the operation is finished, the nerve detection module with higher cost can be taken down and can be reused after the disinfection treatment, and the electric coagulation forceps module can be abandoned after the disinfection treatment according to the disposable medical instrument use standard, so that the manufacturing cost and the use cost of the bipolar electric coagulation forceps with the nerve detection function and the cutting hemostasis function are greatly reduced, the function is well used, the economic effect is obvious, and the electric coagulation forceps are more suitable for market popularization.
Example 2:
the embodiment of the application discloses bipolar electric coagulation forceps with a nerve detection function. Referring to fig. 8, the difference from embodiment 1 is that: the anti-false touch mechanism comprises a propping block 4 fixedly connected to the push button 24, and a third transition surface 41 is arranged on one side of the propping block 4 facing the offset 17; when the push button 24 pushes the probe 23 to protrude from the end of the forceps tip 13 away from the forceps handle 12, the offset 17 is pushed by the offset block 4 to protrude out of the through hole 16.
Under different use demands, the propping block 4 can be set to be long strip-shaped along the length direction of the probe 23, so that when the pushing button 24 just pushes the probe 23, the propping block 4 can push the propping pin 17 to extend out of the through hole 16 so as to limit the two forceps handles 12, and the safety when the electric coagulation forceps module is switched to the nerve detection module can be ensured to the greatest extent; alternatively, the abutment 4 is disposed at an end of the probe 23 away from the forceps tip 13, and when the probe 23 is extended to the detection position, the abutment 4 abuts against the abutment 17, so that the two forceps handles 12 are limited only when the nerve detection operation is performed.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
