Description

组合式电动套扎注射器 Combined electric ligation syringe

技术领域 FIELD

[0001]本发明涉及一种组合式电动套扎注射器,更具体的说,尤其涉及一种推杆长度可更换、一次性更换部分少的用料节约型组合式电动套扎注射器。 [0001] The present invention relates to a combined power injector ligation, more particularly, more particularly to a putter length replaceable, disposable replacement material saving modular electric part ligation less syringe.

背景技术 Background technique

[0002]医用吸注套扎器作为一种使用方便的医用治疗工具,其主要用于痔疮的治疗。 [0002] Medical suction Note ligation as a convenient tool for a medical treatment, which is mainly used for the treatment of hemorrhoids. 专利号为CN200520081522.5、发明名称为医用多能吸注套扎器的发明专利文件,专利号为CN200920030932.5、发明名称亦为医用多能吸注套扎器的专利文件,以及专利号为CN201110170819.9、发明名称为医用注套治疗仪的发明专利文件,均公开了一种对病人病灶(如痔疮)进行治疗的医疗器械。 Patent No. CN200520081522.5, entitled pluripotent aspirating and dispensing a medical ligation device of Patent Document invention, Patent No. CN200920030932.5, also entitled pluripotent aspirating and dispensing a medical device ligation patent documents, and patent No. CN201110170819.9, entitled injection sleeve medical treatment device in Patent document invention, both disclose a kind of medical device patient lesions (such as hemorrhoids) undergoing therapy. 这三篇文件中所公开的注套治疗仪,均采用手指扣动扳机进行吸附,由于要把病人的病灶处吸附进前端的吸盘内,再进行注射药物和套扎胶圈,势必要求活塞腔内产生较大的负压,这就要求医生需用很大的力度来扣动扳机,对于女医生或者瘦弱的男医生来说,很难顺利的扣动扳机,因此很难完成吸附、注射和套扎治疗。 This document disclosed in the three sets of injection treatment, are used to pull the trigger finger adsorption, since the lesions of patients should adsorbed into the front end of the chuck, and then ligation of the injectable pharmaceutical apron, will require that the piston chamber within a greater negative pressure, which requires doctors required a lot of strength to pull the trigger, for female doctors or emaciated male doctors, find it difficult to pull the trigger, it is difficult to complete adsorption, and injection ligation.

[0003] 为了克服手动吸真空所带来的不便于操作的缺点,专利号为CN201410348987.6、发明名称为一次性注射套扎治疗器的发明专利文件,公开了一种结构简单、成本低廉的注射套扎治疗器,其采用吸负压栗进行自动吸真空,使得整个注射套扎治疗器使用起来十分方便,也适于力气十分小的女医生操作。 [0003] To overcome the disadvantages of the manual suction vacuum is not easy to operate brought Patent No. CN201410348987.6, entitled Disposable injection device of Patent Document ligation invention, it discloses a simple structure, low cost injection ligation treatment device, which employs vacuum suction Li automatic vacuum suction, so that the entire injection ligation is very convenient to use, are also suitable for very small effort female doctor operation. 对于这种形式的治疗器来说,在使用的过程中,需要将吸负压装置与枪体相连接,扭转的力度过小,易造成连接处漏气,扭转力度过大,易发生连接处断裂;由于吸负压装置频繁使用,需频繁连接,易造成吸负压装置连接处损坏。 For this form of treatment is, in the process used, it is necessary suction negative pressure device connected to the gun body, torsional strength is too small, easily lead to junction leakage, torsional strength is too large, prone to junction break; frequently used when the suction negative pressure device, the frequent need to connect easily damaged vacuum suction device connection. 再者,由于整个枪身均为一次性使用,无疑会造成材料的浪费;最后,由于其采用牵引绳来推动外围的推管进行运动,这种驱动形式组装起来繁琐,不利于批量生产。 Furthermore, since the entire Barrel are one-time use, it will cause the waste material; and finally, because of its use of traction rope to push the periphery of the push tube movement, this form of assembled drive cumbersome, is not conducive to mass production.

[0004]上述各种形式的注射套扎治疗器还存在不足之处,例如,根据临床需要在对病人不同深度疾病(如肛肠内痔核、直肠息肉、直肠粘膜脱垂等)进行治疗时,需要进行长杆和短杆的互换,但现有的注射套扎治疗器都不能进行长短杆互换,不能完全满足临床治疗需要。 [0004] The above-described various forms of injection ligation also exist deficiencies, e.g., according to the clinical needs at different depths disease patient (e.g., within the anorectal hemorrhoids, rectal polyp, rectal prolapse etc.) for the treatment, need interchangeable pole and short rods, but the existing injection ligation is interchangeable rod length can not be can not fully meet clinical needs.

[0038]图15给出了图4中C区域的放大图,阶梯槽20按照扳机9的转动方向依次为第一凹槽20-1、第二凹槽20-2、第三凹槽20-3和第四凹槽20-4,第一凹槽20-1的左侧为安装扳机9时的扳机定位面20-5。 [0038] Figure 15 shows an enlarged view of area C in FIG. 4, according to the rotation direction of the stepped groove 20 are sequentially trigger 9 is a first groove 20-1, 20-2 second groove, a third groove 20 3 and a fourth groove 20-4, 20-1 on the left side of the first recess for the installation of the trigger when the trigger is positioned face 9 20-5. 在组装扳机9时,将凸块33贴合在扳机定位面20-5上,即可实现扳机9的装配,此时推动块8恰好位于第一台阶19-1上。 When assembling the trigger 9, the projections 33 are bonded to the positioning surface 20-5 on the trigger, the trigger assembly 9 can be achieved, in which case the push block 8 is located just on the first step 19-1. 在推圈时,扳机9转动第一凹槽20-1的角度,推动块8恰好运动完第一台阶19-1的距离,并实现一次推圈。 When the push ring, the trigger 9 is rotated angle of the first groove 20-1, 19-1 of the first step to promote the complete distance of exactly motion block 8, and to achieve a push ring. 即,每当扳机9转动阶梯槽20上一个凹槽的行程,推动块8也恰好运动完阶梯斜边19上的一个台阶,实现套扎一个胶圈的作用。 That is, each time the trigger 9 is rotated a stepped groove 20 on the stroke of the grooves, the push block 8 also happens to be a complete motion step oblique step 19 on to achieve a ligation apron effect.

[0039]在扣动扳机9的过程中,一个台阶可恰好将一个胶圈推下,当推动块8运动至相邻两台阶的接触位置时,扳机9虽然转动,但推动块8不动,扳机9可对医生的手指产生一次“落空感”,同时,推动块8与后一个台阶接触时并发出“啪”的响声,这样,每当推下一个胶圈时,相当于从“听觉”和“感觉”上都在提醒医生胶圈已经被推下,使得医生使用起来更佳方便。 [0039] In the process of pulling the trigger 9, exactly one step may be a rubber ring is pushed down, when the push block 8 is moved to the contact position of the two adjacent steps, although the trigger 9 is rotated, the push block 8 does not move, 9 may be generated trigger a "sense of frustration" doctor's fingers, while promoting and issued a "popping" sound when in contact with the block 8, after a step, so that, each time a push-down ring, from the equivalent of "hearing" and the "feel" is a reminder of doctors apron has been pushed down so that doctors use to facilitate better.

[0040]第一次推圈完成出现落空感后,扳机9上的凸台33与第二凹槽20-2上的限位面相接处,实现对扳机9的限位作用,使其只能朝第三凹槽20-3所在的方向转动,而不能返回至第一凹槽20-1中。 After [0040] completion of the first lap pushing sense of frustration occurs, the contact projection 33 and the stopper surface on the second recess 20-2, to achieve the effect of the trigger stopper 9 of the trigger 9, so that it only rotatable in the direction where the third notch 20-3, and can not be returned to the first recess 20-1. 通过再次扣动扳机,即可进行第二次推圈,通过四个凹槽的限位和四个台阶对推动块8的驱使,共计可进行4个推圈。 By pulling the trigger again, to a second push rings, promoting the driven piece 8, a total of 4 can be pushed through the ring and four grooves limit four steps.

[0041] 通常情况下,推管6向前运动Xmm(如3mm)可将一个胶圈推下,实现胶圈的套扎,由于阶梯斜边19的存在,每套扎一个胶圈虽然推管6只超前运动了Xmm(如3mm),但扳机9实际的推动距离为大于Xmm(如3mm),大于部分的运动距离为相邻两台阶之间的“空挡”区域,这样就形成了落空感和接触时的响声提示。 [0041] Typically, the forward movement of the push tube 6 to Xmm (eg 3mm) may be a rubber ring is pushed down, the O-ring to achieve ligation, due to oblique step 19, although each bar a push tube apron 6 to Xmm ahead of the motion (eg 3mm), 9 but actually pushed the trigger greater than the distance to Xmm (eg 3mm), is greater than the moving distance portion is "neutral" zone between two adjacent steps, thus forming a sense of frustration and when the sound of contact tips.
