In this execute clamp ware axle subassembly 100, main shaft 1, push away clamp subassembly 2, percussion subassembly 3 and press from both sides storehouse subassembly 5 from end to head end and set gradually, reset 4 including the connection main shaft 1 resets 41 with the first piece that resets that pushes away clamp subassembly 2, connects the second that main shaft 1 and body 10 resets 42, and connects the third that percussion subassembly 3 and body 10 reset 43.
As will be appreciated by those skilled in the art, the clip cartridge assembly 5 is intended to receive a surgical clip, the head end of which extends into a patient to provide an access port that allows a surgeon to use a trocar to insert a number of different surgical instruments therethrough. In the device of the present invention, the cartridge assembly 5 specifically includes a clamping cartridge 51 for accommodating a surgical clip and a jaw 300 disposed at a head end of the clamping cartridge 51.
In the present device, the tube 10 is provided with a first position-limiting portion 101 and a second position-limiting portion 102 inside thereof, the first position-limiting portion 101 is disposed in a direction close to the end of the second position-limiting portion 102, a position-limiting cavity 103 is formed between the first position-limiting portion 101 and the second position-limiting portion 102, and at least a part of the firing assembly 3 can only move in the position-limiting cavity 103. In this embodiment, the first restoring member 41, the second restoring member 42 and the third restoring member 43 are all springs, and indeed, in other embodiments, other elastic structures may be adopted. The reset element 4 can be compressed or extended to provide a spring force, in this embodiment, referring to fig. 3, in an initial state, the spindle 1 is disposed close to the end direction relative to the first position-limiting part 101; the second reset piece 42 is disposed on the first position-limiting portion 101 (and may also be disposed on the second position-limiting portion 102, and is preferably disposed on the first position-limiting portion 101 from the viewpoint of saving cost and simplifying the spatial structure of the device), and is connected to the spindle 1. When the spindle 1 moves in the head end direction, the second restoring member 42 is compressed. The third resetting piece 43 is arranged on the second limiting part 102 and is connected with the firing assembly 3; when the firing assembly 3 moves in the direction of the head end, the third restoring member 43 is compressed.
Indeed, in other embodiments of the present invention, referring to fig. 6, the second restoring member 1-1 and the third restoring member 1-2 may also provide spring force by being stretched. For example: in an initial state, the main shaft 1-3 is arranged in a direction close to the head end relative to the first limiting part 1-4; the second reset piece 1-1 is arranged on the first limiting part 1-4 and is connected with the main shaft 1-3; when the main shaft 1-3 moves towards the head end direction, the second reset piece 1-1 is stretched. The third resetting piece 1-2 is arranged on the first limiting part 1-4 and is connected with the firing assembly 1-5; when the firing assembly 1-5 moves towards the head end, the third resetting piece 1-1 is stretched.
In other embodiments, the restoring member 4 may also be a combination of compression and tension.
As shown in fig. 3, in the initial state, the first restoring member 41, the second restoring member 42 and the third restoring member 43 are preferably in a pre-compressed state. Although the first restoring member 41 is in the pre-compression state, the elastic force of the spring is not enough to push the pushing and clamping assembly 2 to move, so that when the main shaft 1 is driven by the screw 200 to move towards the head end, the elastic force of the first restoring member 41 is increased, and the pushing and clamping assembly 2 is further pushed to move towards the head end at the first time (the second restoring member 42 and the third restoring member 43 are the same). Specifically, referring to fig. 4, in the clip applier shaft assembly 100, the clip pushing assembly 2 includes a clip pushing rod 21 and a clip delivering piece 22 disposed on the clip pushing rod 21, and the clip pushing rod 21 is used for pushing the first surgical clip 50 near the head end in the clip loading bin 51 to move towards the head end. The clip transporting piece 22 comprises a clip transporting part 221 arranged at the head end, and in an initial state, the clip transporting part 221 is provided with the rear end of the first surgical clip 50; when the surgical clip is delivered, the screw rod 200 drives the main shaft 1 to move towards the head end direction, so as to push the clip pushing rod 21 to deliver the first surgical clip 50 to the forceps holder 300, at this time, the clip delivering piece 22 moves towards the head end direction along with the clip pushing rod 21, and when the clip is completely delivered, the clip delivering part 221 abuts against and is arranged at the head end of the clip containing bin 51, so as to block the subsequent surgical clip. In addition, since the head end of the clip transporting piece 22 abuts against the clamping bin 51, when the screw 200 continues to drive the spindle 1 to move in the head end direction, the clamping pushing rod 21 and the clip transporting piece 22 are stationary.
Referring to fig. 5, after the pushing and clamping is completed, the screw rod 200 continues to drive the main shaft 1 to move toward the head end, so as to push the triggering assembly 3 to complete triggering. Specifically, the firing assembly 3 includes a firing shaft 31 and a firing plate 32 coupled to the jaws 300. The firing shaft 31 is provided with a firing block 312 and a wing 311 at the head end and the tail end, respectively, the jaw 300 is provided with an X-shaped slot (not shown), and the firing block 312 is inserted into the X-shaped slot through a connecting pin (not shown) to be connected with the jaw 300. The wing part 311 is limited in the limit cavity 103, the third reset piece 43 is connected to the wing part 311, and during the firing process, when the main shaft 1 abuts against the wing part 311 to push the firing shaft 31 to move towards the head end, the third reset piece 43 is compressed at the moment. Preferably, in the initial state, a preset distance is provided between the main shaft 1 and the wing portion 311, and the length of the preset distance is slightly greater than (theoretically equal to) the length of one surgical clip, so as to ensure that the main shaft 1 just touches the wing portion 311 when the surgical clip is fed into the forceps holder 300. When the main shaft 1 pushes the firing shaft 31 to move in the head-end direction, since the striking plate 32 and the jaw 300 connected thereto are fixed in the axial direction, the striking plate 32 and the jaw 300 move in the distal direction with respect to the firing shaft 31, at which time the connecting pin on the firing block 312 moves in the X-shaped slot to close and/or shape the jaw 300 and the surgical clip positioned or loaded therebetween.
Preferably, the X-slot is sized to couple the entire length of the pin movement required to move the jaws 300 from the fully open position to the fully closed position, thereby defining and controlling the length of the closing stroke of the jaws 300.
Referring now to fig. 3-5, the clip feed and firing including the clip applier shaft assembly 100 operably connected to a clip applier working head and handle assembly is shown and described. At the initial state, the forceps 300 is in an open state, at this time, the driving rod 200 drives the main shaft 1 to move towards the head end direction, because the first resetting piece 41 and the second resetting piece 42 are both in a pre-compression state, when the driving rod 200 drives towards the head end, the main shaft 1 and the pushing and clamping assembly 2 move towards the head end direction at the first time, as the pushing and clamping assembly 2 advances towards the head end, the pushing and clamping rod 21 sends the first surgical clip 50 close to the head end into the forceps 300, at this time, the clamping part 221 on the clamping piece 22 abuts against the head end of the clamping bin 51, and the second surgical clip is prevented from moving into the forceps 300. At this time, the clip feeding process is completed, the main shaft 1 contacts with the flank portion 311 of the firing shaft 31, and when the driving rod 200 is continuously driven, the main shaft 1 pushes the firing shaft 31 to advance towards the head end direction, and the clip feeding assembly 2 stops moving due to the fact that the clip feeding portion 211 abuts against the clip loading bin 51. As the firing shaft 31 advances, the jaws 300 complete firing (closing) under the action of the firing block 312.
When the firing is completed, the driving rod 200 moves reversely to the initial position, and the main shaft 1, the clip pushing device 2 and the firing shaft 31 return to the initial position under the action of the first restoring element 41, the second restoring element 42 and the third restoring element 43, wherein the clip transporting sheet 22 returns to the back of the first surgical clip at this time. And repeating the previous steps continuously until the surgical clips are completely fired, and finally exposing the head ends of the clip pushing rods 21 to prompt the user to replace the instruments.
Referring to fig. 7, another embodiment of the present invention further provides a medical surgical clip applier, which includes a handle assembly 400, a working head 500 selectively connected to the handle assembly 400, and a clip applier shaft assembly 100 connected to the working head 500 (see the above embodiment, fig. 1 to 6). It will be appreciated by those skilled in the art that clip applier may be operated by providing an actuator assembly other than handle assembly 400, and that handle assembly 400 or actuator assembly are well known in the art and will not be described in detail herein. The working head 500 is mainly provided with a driving device, and those skilled in the art should understand that the existing clip applier generally adopts a screw driving or ratchet driving manner, which is the prior art and will not be described herein.
Compared with the prior art, the invention has the beneficial effects that: according to the clip applier shaft assembly and the medical operation clip applier, the reset piece is arranged in the pipe body, when the driving device of the medical operation clip applier drives the main shaft to move towards the head end, the second reset piece deforms, the first reset piece serves as a connecting piece to further push the push-clip assembly to move, then the main shaft is in contact with the firing assembly and pushes the firing assembly to move towards the head end, and the third reset piece deforms; therefore, after the surgical clamp is finally fired and the driving is stopped, the main shaft, the clamp pushing assembly and the firing assembly are reset by the reset force generated by the reset piece. Therefore, the clamp applier shaft assembly and the medical surgical clamp applier simplify the operation process and reduce surgical risks only by arranging the driving main shaft to move and finish the functions of pushing and clamping, delivering and triggering and resetting the device.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
