Detailed description of the invention
Core of the present utility model is to provide a kind of anal-surgery auxiliary device getting better quality pocket used in anal-surgery.
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See Fig. 1-Fig. 7, the anal-surgery auxiliary device that an embodiment of the present utility model provides, comprise: anus-expanding unit 1, anus-expanding unit 1 comprise hollow expansion anus body 12, be positioned at expand anus body 12 far-end guidance part 13, be positioned at the broadside 11 expanding anus body 12 near-end, the sidewall expanding anus body 12 is provided with the first opening 14; Actuator 2, actuator 2 comprise hollow control agent 22, be positioned at the introduction part 23 of control agent 22 far-end, be positioned at the handle 21 of control agent 22 near-end, actuator 2 can insert anus-expanding unit 1 inside and can rotate relative to anus-expanding unit 1, and the sidewall of control agent 22 is provided with the second opening 24 that can be corresponding with the first opening 14.When performing the operation, first anus-expanding unit 1 is inserted affected part, when observing sensation first opening 14 and being excessive, insert actuator 2, make the second opening 24 of actuator 2 corresponding with the first opening 14, now rotate this actuator 2, when the control agent 22 of actuator 2 shelters from part the first opening 14, then reach correct position, can stop the rotation, now the openings of sizes of anal-surgery auxiliary device and the in the same size of hemorrhoid, complete adjustment, and then doctor can perform the operation further.Due to the openings of sizes of anal-surgery auxiliary device and the in the same size of hemorrhoid, tissue is in tight state, and needs suture site to be all exposed to opening part, and it is more abundant that this anal-surgery auxiliary device makes doctor play pocket, and quality is higher.
Further, for ease of inserting affected part, control agent and expansion anus body are cylindrical shape, or other streamlined in shape, and the external diameter of described control agent equals the internal diameter of described expansion anus body substantially.
On the basis of above-described embodiment, further, the side wall inner surfaces expanding anus body 12 is provided with projection 121, the wall outer surface of control agent 22 is provided with protuberance 221, when actuator 2 inserts anus-expanding unit 1 inside completely and control agent 22 can not continue to advance in expansion anus body 12, protuberance 221 contacts along 1211 with the lower of projection 121 just along 2211.Now anus-expanding unit 1 and actuator 2 axial restraint, ensures that doctor makes apparatus can not axially-movable playing pocket.
Further, the surface of the sidewall between the projection 121 expanding anus body 12 to guidance part 13 is inclined-plane, the protuberance 221 of control agent 22 is also inclined-plane to the sidewall between introduction part 23, the surface of the sidewall between the setting projection 121 that expands anus body 12 to guidance part 13 is the first inclined-plane 122, the protuberance 221 of setting control agent 22 is the second inclined-plane 222 to the sidewall between introduction part 23, when actuator 2 is inserted into anus-expanding unit 1, first inclined-plane 122 and the second inclined-plane 222 form inclined-plane self-locking, actuator 2 cannot move relative to anus-expanding unit 1, ensure that the stability of apparatus in operation.
In addition, the first inclined-plane 122 can arrive whole inner surfacies of the sidewall between guidance part 13 for the projection 121 expanding anus body 12.Further, the first inclined-plane 122 also can arrive the portion inner surface of the sidewall between guidance part 13 for the projection 121 expanding anus body 12.Second inclined-plane 222 can be the protuberance 221 whole outer surfaces to the sidewall between introduction part 23 of control agent 22.Further, the second inclined-plane 222 also can be protuberance 221 partial outer face to the sidewall between introduction part 23 of control agent 22.
Further, the length on the first inclined-plane 122 and the second inclined-plane 222 is unanimous on the whole, the angle of inclination on the first inclined-plane 122 and the second inclined-plane 222 is unanimous on the whole, and when control agent 22 insert completely expand in anus body 12 and propelling can not be continued time, first inclined-plane 122 and the second inclined-plane 222 close contact, now apparatus is more excellent state.
Further, the sidewall expanding anus body 12 is provided with multiple first opening 14, and the sidewall of control agent 22 is provided with multiple second opening 24, and multiple first opening 14 can with multiple second opening 24 one_to_one corresponding.Thus, the patient of multiple hemorrhoid can be had to use for anal canal inwall, and the corresponding multiple hemorrhoid of multiple opening are performed the operation.
Further, anal-surgery auxiliary device also comprises and throws off device 3.This disengagement device 3 comprises flange 32 and contact part 31, and the far-end of the guidance part 13 of anus-expanding unit 1 is provided with circular hole, throws off the contact part 31 of device 3 and can to stretch in circular hole and the distal contact of introduction part 23 with actuator 2.When performing the operation, after finishing the purse string suture of hemorrhoid, anal-surgery auxiliary device being extracted, then with throwing off device 3, anus-expanding unit 1 and actuator 2 can be separated, this anal-surgery auxiliary device can be reused thus.
Near-end herein, far-end limited according to industry practice, and be namely near-end from person close to doctor during operation, opposite end is far-end.
Above anal-surgery auxiliary device provided by the utility model is described in detail.Apply concrete example herein to set forth principle of the present utility model and embodiment, but the explanation of above embodiment just understands principle of the present utility model and core concept thereof for helping, the restriction not to this utility model protection domain.Should be understood that; for those skilled in the art; under the prerequisite not departing from this utility model principle, can also carry out some improvement and modification to this utility model, these improve and modify and also fall in the protection domain of this utility model claim.
