Detailed Description

Technical scheme in the embodiment of this application is entering into the inside in-process of uterus through the cervix for solving above-mentioned drag hook, causes the damage to the tissue around the cervix easily, causes the problem of secondary injury, and the general thinking is as follows:

referring to fig. 1-4, the hysteromyoma pulling hook for hysteroscopy includes an auxiliary pushing assembly 10 and a pulling assembly 20.

Wherein, supplementary subassembly 10 that pushes in can assist and send into memory metal willow nail hook 210 inside the uterus, and the myoma that draws the subassembly 20 can be with the uterus inside drags out.

Referring to fig. 1, 2, 3 and 4, the auxiliary pushing assembly 10 includes a pushing cylinder 110 and a pushing cylinder 120, one end of the pushing cylinder 120 is slidably disposed inside the pushing cylinder 110, and specifically, both the pushing cylinder 110 and the pushing cylinder 120 may be made of medical glass material or plastic material; wherein, stretch into the palace chamber through the hysteroscope operation hole earlier, under the hysteroscope supervision, will push into a section of thick bamboo 110 and enter into the cervix inside through the vagina until entering into uterus inside to myoma position, then push away a push rod section of thick bamboo 120, make memory metal willow nail hook 210 break away from pushing into a section of thick bamboo 110 inside and fix on uterus myoma tumor body, then will push into a section of thick bamboo 110 and withdraw from, keep pulling rope 220, make pulling rope 220 other end be located vagina department, put into the hysteroscope again, then pull pulling rope 220, place non-energy apparatus in the operation hole, cooperate with the strength of memory metal willow nail hook 210 of outside tractive, reach the purpose of going out myoma glass. The arrangement of the push rod barrel 120 facilitates the memory metal rivet hook 210 to be pulled out from the interior of the push rod barrel 110.

The plunger 140 is fixedly connected to one end of the plunger barrel 120 close to the memory metal willow nail hook 210, and specifically, the plunger 140 is disposed at the through hole to facilitate the passing of the pulling rope 220. And the piston 140 is located inside the push cylinder 110, and in particular, the piston 140 is welded and fixed with the push cylinder 120. The memory metal willow nail hook 210 can be pushed out and pushed into the barrel 110 through the piston 140, and the hysteromyoma can be fixed.

The top end of the pushing cylinder 110 is fixedly connected with a limiting cylinder 130 matched with the piston 140, specifically, the limiting cylinder 130 and the pushing cylinder 110 are integrally formed and can be made of the same material as the pushing cylinder 110. The arrangement of the limiting cylinder 130 enables the piston 140 to just push out the memory metal willow nail hook 210, and the piston 140 cannot be pulled out from the interior of the push-in cylinder 110.

The end of the plunger barrel 120 away from the piston 140 is provided with a push ring 150, and specifically, the push ring 150 and the plunger barrel 120 are integrally formed and can be made of the same material as the plunger barrel 120. When the memory metal willow nail hook 210 needs to be pushed out, the thumb presses the push-in ring 150, so that labor is saved and safety is improved during pushing.

The bottom end of the pushing cylinder 110 is provided with a limiting ring 160 matched with the pushing ring 150, and specifically, the limiting ring 160 and the pushing cylinder 110 are integrally formed and can be made of the same material as the pushing cylinder 110. Through the arrangement of the limiting ring 160, when the piston 140 is pushed, the thumb presses the push-in ring 150, and the index finger and the middle finger are respectively positioned at the upper side and the lower side of the limiting ring 160, so as to push the push-rod barrel 120. Making it more stable when pushed.

The inner diameter of the limiting cylinder 130 is larger than the outer diameter of the piston 140. The piston 140 is limited and cannot be pulled out from the interior of the push-in cylinder 110.

The outer diameter of the piston 140 is smaller than the inner diameter of the insertion cylinder 110. The piston 140 is conveniently pushed inside the push-in cylinder 110, and the push-out of the memory metal willow nail hook 210 is realized.

The diameter of the memory metal hook 210 is larger than the inner diameter of the piston 140. Wherein, the memory metal nail hook 210 can not fall into the piston 140, which causes inconvenience to the operation.

Referring to fig. 1 and 2, the pulling assembly 20 includes a memory metal pintle hook 210 and a pulling rope 220, one end of the pulling rope 220 penetrates through the push-in barrel 110 and is connected to the memory metal pintle hook 210, the memory metal pintle hook 210 is arrow-shaped and is retracted when located inside the push-in barrel 110, and the memory metal pintle hook 210 is deployed when located outside the push-in barrel 110. Wherein, catch on hysteromyoma through memory metal willow nail hook 210, then realize pulling hysteromyoma through dragging the tractive rope 220. The memory metal willow nail hook 210 is retracted inside the push-in barrel 110 and unfolded outside the push-in barrel 110, so that the memory metal willow nail hook 210 cannot scratch the inner wall assembly of the cervix when entering the uterus, and the traction of hysteromyoma is not influenced.

When the application is used:

stretch into the palace chamber through the hysteroscope handle hole earlier, under hysteroscope supervision, will push a section of thick bamboo 110 and enter into the cervix through the vagina inside until entering into the uterus inside to myoma position, then push away a push rod section of thick bamboo 120, make memory metal willow nail hook 210 break away from pushing into a section of thick bamboo 110 inside and fix on the uterus myoma tumor body, then will push a section of thick bamboo 110 and withdraw from, remain the tractive rope 220, make the other end of tractive rope 220 be located vagina department, place the hysteroscope once more, then stimulate the tractive rope 220, place non-energy apparatus in the handle hole, with the strength cooperation of the memory metal willow nail hook 210 of outside tractive, reach the mesh that goes out myoma glass.

In conclusion, the memory metal willow nail hook 210 is retracted inside the push-in cylinder 110 and expanded outside the push-in cylinder 110, so that the memory metal willow nail hook 210 cannot scratch the cervical inner wall assembly when entering the uterus, and the traction of uterine fibroids is not influenced.

Finally, it should be noted that: it should be understood that the above examples are only for clearly illustrating the present invention and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications of the invention may be made without departing from the scope of the invention.
