Background
Echinococcosis or echinococcosis (echinococciosis) is a chronic parasitic disease caused by a person infecting larvae of echinococcosis (echinococcosis). The clinical manifestations of this disease vary depending on the location, size and presence of complications of the bag. Echinococcosis has long been considered a zoonotic parasitic disease of humans and animals (livestock), called animal-derived disease, but epidemiological investigation has shown in recent years that it is called endemic parasitic disease.
The echinococcosis bag sequentially comprises a fibrous layer, a cuticle, a germinal layer, an ascus and a cyst fluid from outside to inside, and the conventional drug treatment has no effect in the treatment of the echinococcosis due to the protection effect of the fibrous layer and the cuticle. The difficulty of echinococcosis in the surgical procedure is: 1. the hair growth layer is attached with a plurality of raw head knots floating in the cyst fluid, and the raw head knots can be planted in the abdominal cavity once overflowed, namely, the positions where the raw head knots reach can be developed into new insect cysts at the positions. 2. The cyst fluid contains foreign protein, so that the foreign protein is easy to allergic once overflowed, and even death occurs when serious. For both reasons, cystic insects are currently considered undesirable for laparoscopic surgery.
At present, the main treatment modes are total excision of an outer sac (liver and fibrous layer) and excision of an inner sac (stratum corneum and germinal layer) under the condition of open abdomen, but the open abdomen operation is widely known to patients, and has large wounds, severe pain and slow postoperative recovery.
Therefore, how to smoothly discharge the cyst fluid out of the cyst cavity and prevent the cyst fluid from overflowing so as to realize the endoscopic treatment of the echinococcosis treatment operation is a great technical problem to be solved by the person skilled in the art.

One end of the central rotating shaft 3 extending out of the liquid suction pipe 2 forms a power transmission section 5, and the power transmission section 5 is in transmission connection with a driving mechanism arranged in the handle 1 and drives the central rotating shaft 3 through the driving mechanism. The liquid suction pipe 2 is also provided with a liquid discharge pipe 6, and the liquid discharge pipe 6 is positioned near the right end of the liquid suction pipe 2 and is communicated with the inside of the liquid suction pipe 2, and the pumped bag liquid in the liquid suction pipe 2 is discharged from the liquid discharge pipe 6.
The driving mechanism of the present invention has a plurality of specific structures, for example: 1. the drive mechanism is an L-shaped rocker arm which is connected to the power transmission section 5, which is extremely simple, but which has the disadvantage that it requires two hands for operation and is therefore not described too much in this invention. 2. The invention can also adopt an electric driving mode, but the mode needs to add components such as a motor, a battery, a controller and the like, has complex structure and high cost, and increases the burden of hands of doctors after increasing the weight, and is not particularly applicable to the treatment of the echinococcosis, so the invention is not described too much.
The present invention is focused on a driving mechanism with a smart structure, as shown in fig. 1, the driving mechanism comprises a trigger assembly and a gear assembly which are arranged in a handle 1, and the handle 1 is generally formed by splicing symmetrical two halves, and is connected by clamping and positioning a matched bolt.
The trigger assembly comprises a trigger plate 7 and a return spring 8, wherein the upper part of the trigger plate 7 and the handle 1 form a hinge joint capable of swinging along the left-right direction through a first pin shaft, the first pin shaft is generally and directly fixedly arranged on two sides of the trigger plate 7, and then a shaft hole sleeve for penetrating the pin shaft is arranged on the inner wall of the handle 1. Of course, a pin hole may be directly provided on the trigger plate 7, and a pin shaft may be passed through the pin hole to form a hinge. The former is generally used for mounting in view of convenience in processing and assembly.
The top of the trigger plate 7 is in a sector shape, an arc-shaped transmission rack 9 is arranged on the arc edge of the sector, and the arc-shaped transmission rack 9 is connected with a gear assembly. The left side wall of the handle 1 is provided with a yielding port 10, the middle part and the lower part of the left side of the trigger plate 7 extend out of the handle 1 through the yielding port 10 to form a holding part, and a groove matched with fingers can be formed in the holding part, so that the comfort is stronger. One end of the return spring 8 is connected with the upper part of the right side of the trigger plate 7, the other end is connected with the inner wall of the right side of the handle 1, and the return spring 8 can be directly connected with the inner wall of the handle 1 or indirectly connected with the inner wall of the handle 1 through a short rod, a short edge, a reinforcing rib and the like in the handle 1.
The most elaborate driving mechanism according to the present invention is that the gear assembly comprises a first wheel axle 11, a second wheel axle 12 and a third wheel axle 13, wherein a first main gear 14 and a first auxiliary gear 15 are coaxially arranged on the first wheel axle 11, a second main gear 16 is arranged on the second wheel axle 12, and a third main gear 17 and a third auxiliary gear 18 are coaxially arranged on the third wheel axle 13, as shown in fig. 3. The front and rear side walls of the handle 1 are respectively provided with a group of first mounting short pipes 19, a group of second mounting short pipes 20 and a group of third mounting short pipes 21 corresponding to the positions of the first wheel shaft 11, the second wheel shaft 12 and the third wheel shaft 13, two ends of the first wheel shaft 11, the second wheel shaft 12 and the third wheel shaft 13 are respectively inserted into the first mounting short pipes 19, the second mounting short pipes 20 and the third mounting short pipes 21, the second mounting short pipes 20 are elliptical, and the second wheel shaft 12 can rotate in the mounting short pipes 20 and can also move in a short distance. The power transmission section 5 of the central rotating shaft 3 is a worm, the third main gear 17 is a turbine, and the power transmission section 5 is meshed with the third main gear 17 to realize the function of power reversing.
The first main gear 14 is meshed with the transmission rack 9 at the top of the trigger plate 7, and spline teeth of the first auxiliary gear 15 and the third auxiliary gear 18 are matched with the second main gear 16. When the first main gear 14 rotates, the second main gear 16 can be driven to rotate, and the second main gear 16 and the third auxiliary gear 18 are pushed to be close and meshed.
When the driving mechanism works, a doctor holds the handle 1 by one hand, repeatedly squeezes the trigger plate 7, the trigger plate 7 swings back and forth around the first pin shaft, and when the trigger plate 7 swings leftwards, the transmission rack 9 directly drives the first main gear 14 to rotate, and at the moment, the first auxiliary gear 15 coaxially arranged with the first main gear 14 also rotates, so that the second main gear 16 is driven to rotate. Meanwhile, since the second wheel shaft 12 where the second main gear 16 is located is installed in the elliptical second installation short pipe 20, the first auxiliary gear 15 and the second main gear 16 are still pushed to move towards a position close to the third wheel shaft 13 until contacting with the third auxiliary gear 18 on the third wheel shaft 13 under the state of maintaining engagement, so as to drive the third wheel shaft 13 to rotate. The power of the third wheel axle 13 is transmitted to the central spindle 3 via the third main gear 17 and the power transmission section 5 of the central spindle 3.
When the doctor releases the holding of the trigger plate 7, the reset spring 8 drives the trigger plate 7 to reset, and the transmission rack 9 drives the first main gear 14 to reversely rotate. At this time, the second wheel shaft 12 is retracted when it is reversed due to the reverse rotation, so that the second main gear 16 is no longer in contact with the third sub gear 18, thereby achieving the power disengagement. Therefore, when the trigger plate 7 is held, the central rotating shaft 3 is driven to rotate, and when the trigger plate 7 is released, the power is released, the invention can not cause the central rotating shaft 3 to rotate reversely, so that the suction is not influenced.
Considering that saturated saline is required to be continuously supplemented to flush the sac cavity in the process of sucking the sac liquid, the invention preferably further comprises an outer sleeve 22 coaxially sleeved outside the liquid suction pipe 2, wherein the outer sleeve 22 is provided with a water inlet pipe 23, the water inlet pipe 23 is positioned near the right end of the outer sleeve 22 and is communicated with the liquid suction pipe 2, and the liquid discharge pipe 6 penetrates out of the outer sleeve 22 and forms a seal with the outer sleeve 22, as shown in fig. 1. The water inlet pipe 23 is used for flushing saturated brine, the brine flows through the area between the outer sleeve 22 and the liquid suction pipe 2, is discharged from the left end in fig. 1, repeatedly washes the capsule cavity, and is matched with the liquid suction pipe to be pulled out until the inside of the capsule cavity is cleaned.
In order to facilitate the installation of the outer sleeve 22, the pipette 2 and other components, a threaded connector 24 matched with the outer sleeve 22 is arranged at the upper part of the left side of the handle 1, and an external thread is arranged at the right end of the threaded outer sleeve 22 and is in threaded fit with the threaded connector 24. In this case, the outer sleeve 22 and the pipette 2 are generally integrally formed, and when the pipette is mounted, as shown in fig. 1, the right end of the central shaft 3 is inserted into the grip 1, the power transmission section 5 of the central shaft 3 is connected to the driving structure, and then the outer sleeve 22 is rotated to form a fit with the screw connector 24. Meanwhile, after the mode is adopted, when the disposable plastic material is used next time, only the contaminated outer sleeve 22 part, the liquid suction pipe 2 part and the central rotating shaft 3 part need to be replaced, namely the outer sleeve 22, the liquid suction pipe 2, the central rotating shaft 3 and the spiral teeth 4 are all disposable plastic materials. When the handle 1 is replaced, the handle is not required to be replaced every time, so that resources are further saved, and medical loss is reduced.
In order to further improve the performance of the present invention, as shown in fig. 4, it may be further preferable that the left end of the central rotating shaft 3 is further provided with a crushing assembly, the crushing assembly includes a plurality of movable crushing rods 25 fixed on the peripheral surface of the central rotating shaft 3 and an end supporting ring 26 sleeved on the central rotating shaft 3, and the end supporting ring 26 is connected with the liquid suction pipe 2 through a plurality of static crushing rods 27. Because the left end of the central rotating shaft 3 is overhung too much, the end supporting ring 26 can play a role of reinforcing support, so that the rotation of the central rotating shaft 3 is more stable. Meanwhile, in the process that the central rotating shaft 3 drives the movable crushing rod 25 to rotate, the movable crushing rod can crush ascus contained in the cyst fluid to destroy the ascus activity. In addition, the static pulverizing rod 27 can be matched with the dynamic pulverizing rod 25 to improve the shearing force and the pulverizing effect on the ascus in addition to the function of forming the end supporting ring 26.
As shown in fig. 1, a stabilizing short tube 30 may be further disposed on the inner wall on the right side of the grip 1, the position of the stabilizing short tube 30 is opposite to the power transmission section 5 of the central rotating shaft 3, the power transmission section 5 is matched with the stabilizing short tube 30 and is inserted into the stabilizing short tube 30, and the stabilizing short tube 30 is used for improving the stability of the power transmission section 5 of the central rotating shaft 3 in the rotating process and playing an auxiliary positioning role in the mounting process.
In addition, the invention also discloses a matched special puncture assembly for echinococcosis, as shown in fig. 5, the puncture assembly comprises a cylindrical sheath shell 31 and a puncture tip rod 32 penetrating through the sheath shell 31.

In the using process, the expansion air bag 33 positioned at the outer side is firstly inflated from the double-channel gas injection port 34, then the bag puncture is carried out, and the bag liquid leakage caused by the pressure in the bag at the moment of bag breaking can be effectively prevented through the expansion air bag 33 at the outer side. Then, as shown in fig. 6, when the inflatable air bags 33 positioned on the inner side are inflated through the two-channel gas injection port 34, the two inflatable air bags 33 jointly clamp the bag wall, so that the fixation is more stable, the bidirectional blocking is realized, and the probability of leakage of bag liquid is minimized. Finally, as shown in fig. 7, the puncture tip 32 is removed, so that the bag fluid can be sucked by the aspirator.
