本发明涉及一种医疗器械，尤其涉及一种用于腹腔镜手术中的免气腹支撑装置。The invention relates to a medical device, in particular to a pneumoperitoneum-free support device used in laparoscopic surgery.
背景技术Background technique
腹腔镜手术是一门新发展起来的微创方法，是目前来说比较先进的手术治疗方法，可以治疗多种类型的疾病。作为先进的微创技术，由于腹腔镜手术手术创伤小、出血少、受术者术后可以恢复迅速，目前在临床已得到广泛应用。传统腹腔镜手术利用CO2气腹技术来制造手术操作空间。由于CO2气腹对呼吸、循环系统及妊娠胎儿有诸多的不良影响，不适用于机体状况差或患有心脑血管疾病、栓塞性疾病和肺功能不全的患者，人们研制了各种腹壁悬吊装置来进行免气腹的腹腔镜手术。但现有免气腹技术使用柯氏针穿入腹壁进行腹壁悬吊容易对患者进行二次创伤，腹壁悬吊拉力会使双侧腹壁向中间聚集，挤压肠管向中间集中，导致手术空间变小、变窄；肌张力较大时，手术操作空间更会明显缩小，不但因放置皮下钢丝而多做一个4mm切口，且受力集中在悬吊钢丝上，容易对患者腹壁造成损伤，形成的手术空间相对小。Laparoscopic surgery is a newly developed minimally invasive method. It is currently a relatively advanced surgical treatment method and can treat many types of diseases. As an advanced minimally invasive technique, laparoscopic surgery has been widely used in clinical practice due to its small trauma, less bleeding, and rapid postoperative recovery. Traditional laparoscopic surgery uses CO2 insufflation technology to create a surgical operating space. Because CO2 pneumoperitoneum has many adverse effects on breathing, circulatory system and pregnant fetus, it is not suitable for patients with poor physical condition or suffering from cardiovascular and cerebrovascular diseases, embolism diseases and pulmonary insufficiency. Various abdominal wall suspensions have been developed. Device for gas-free laparoscopic surgery. However, the existing pneumoperitoneum-free technology uses Kirschner needles to penetrate the abdominal wall for abdominal wall suspension, which is easy to cause secondary trauma to the patient. The tension of the abdominal wall suspension will make the bilateral abdominal walls gather in the middle, squeeze the intestines to concentrate in the middle, and cause the operation space to change. Smaller and narrower; when the muscle tension is high, the operating space will be significantly reduced, not only because of the placement of subcutaneous steel wires, an additional 4mm incision will be made, but also the force will be concentrated on the suspension steel wires, which will easily cause damage to the patient's abdominal wall, resulting in The operating space is relatively small.

具体实施方式Detailed ways
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述。In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
参照图1￣图3所示的结构示意图。Refer to the schematic diagram of the structure shown in Figure 1 ~ Figure 3.
本发明实施例的一种伞式腹腔镜免气腹支撑装置，包括主杆1、移动套体2、若干撑开爪3、铰接杆4、底座5。An umbrella-type laparoscope-free pneumoperitoneum support device according to an embodiment of the present invention includes a main rod 1 , a moving sleeve 2 , a number of spreading claws 3 , a hinged rod 4 , and a base 5 .
移动套体2滑动设置于主杆1上，在人力或者机械驱动力的情况下沿着主杆1上下移动。The moving sleeve 2 is slidably arranged on the main rod 1, and moves up and down along the main rod 1 under the condition of manpower or mechanical driving force.
在本实施例中，优选为在移动套体2下侧周面等间距对称设置六个撑开爪3，撑开爪3的中部与铰接杆4的尾端相铰接。In this embodiment, preferably, six spreading claws 3 are symmetrically arranged at equal intervals on the lower peripheral surface of the moving sleeve 2 , and the middle part of the spreading claws 3 is hinged to the tail end of the hinge rod 4 .
底座5固定设置于主杆1下端，底座5上的过渡曲面边缘开有直槽孔51，铰接杆4的头端的限位孔41与直槽孔51铰接。The base 5 is fixedly arranged on the lower end of the main rod 1, and the edge of the transition curved surface on the base 5 has a straight slot 51, and the limit hole 41 at the head end of the hinge rod 4 is hinged with the straight slot 51.
铰接杆4头端设置有U形缺口槽，直槽孔51与U形缺口槽尺寸相当，使本发明在收拢过程中，直槽孔51可吻合收于U形缺口槽内。The articulated rod 4 head end is provided with U-shaped notch groove, and straight slot hole 51 is suitable with U-shaped notch groove size, makes the present invention in the folding process, and straight slot hole 51 can be coincidently received in the U-shaped notch groove.
本发明在使用时，先合拢六个撑开爪3至贴紧主杆1，然后将主杆支架从充气口缓慢斜插入腹腔，通过人力或者机械驱动力带动移动套体2并使铰接杆4 从动向上支起各撑开爪3，通过提起主杆1从而顶起腹部，形成较大的手术操作空间。如图1，当放下主杆1，则移动套体2沿主杆1向上移动时，各撑开爪3 在铰接杆4的带动下收拢，进而收起支架。When the present invention is in use, the six opening claws 3 are first closed to stick to the main rod 1, and then the main rod support is slowly inserted obliquely into the abdominal cavity from the inflation port, and the sleeve body 2 is driven by manpower or mechanical driving force to make the hinged rod 4 Each stretching claw 3 is supported upward from the movement, and the abdomen is lifted up by lifting the main rod 1 to form a larger operation space. As shown in Fig. 1, when the main rod 1 is put down, when the moving sleeve body 2 moves upward along the main rod 1, each stretching claw 3 is brought together under the drive of the hinged rod 4, and then the support is folded up.
在本实施例中，支撑爪形成伞形结构，六个撑开爪3在圆周上360度均匀分布，铰接杆4也为六个且与撑开爪一一对应设置，通过主杆1拉紧并提起腹部时，承受力较大且更加均匀，贴合腹部，不易对腹壁造成伤害，能形成较大的手术空间和手术视野，而撑开爪3与腹壁之间的接触为面接触，更是减小了传统悬吊式无气腹腹腔镜手术线接触对腹壁的伤害。进一步地，主杆1为正六边形或其他多边形形状，与移动套体2之间为轴向导向，便于移动套体2着主杆1 往返移动同时防止移动套体2上下移动时沿主杆1发生扭动，使移动套体2移动时稳定性好。In this embodiment, the supporting claws form an umbrella-shaped structure, and the six spreading claws 3 are evenly distributed on the circumference at 360 degrees. And when the abdomen is lifted, the bearing force is larger and more uniform, fits the abdomen, is not easy to cause damage to the abdominal wall, and can form a larger operation space and operation field of view, and the contact between the stretching claws 3 and the abdominal wall is surface contact, which is more convenient. It reduces the damage to the abdominal wall caused by the wire contact of the traditional suspension type airless laparoscopic surgery. Further, the main rod 1 is in the shape of a regular hexagon or other polygons, and is axially guided with the moving sleeve 2, which is convenient for the moving sleeve 2 to move back and forth along the main rod 1 while preventing the moving sleeve 2 from moving along the main rod when it moves up and down. 1 is twisted, so that the mobile sleeve body 2 has good stability when moving.
底部2顶面具有凸台52，主杆1下端设置有安装凸台52的凹槽11，凸台 52与凹槽11之间设置有限位固定孔53、12，两者之间通过固定销配合紧固，结构稳定，不易发生扭动，便于安装和清洗。There is a boss 52 on the top surface of the bottom 2, and the lower end of the main rod 1 is provided with a groove 11 for installing the boss 52, and a limited fixing hole 53, 12 is arranged between the boss 52 and the groove 11, and the two are matched by a fixing pin. Tight, stable structure, not easy to twist, easy to install and clean.
优选的是，底座5设计的有过渡曲面，当移动套体2沿主杆1向下移动时，撑开爪3能沿过渡曲面缓慢撑开，收到的阻力较小且曲面的设计对撑开爪(3)的撑开具有导向作用，防止撑开爪3沿其他方向撑开破坏结构，进而伤害腹壁。如图3，当移动套体2沿主杆1向上移动时，撑开爪3在铰接杆4的带动下沿过渡曲面收拢，铰接杆4的尺寸与撑开爪3下端开的直槽32相吻合，撑开爪3可容纳于铰接杆4的直槽32内，使其完全贴紧底座，将直径减少到最小，便于撤离腹部。Preferably, the base 5 is designed with a transitional curved surface. When the moving sleeve 2 moves down along the main rod 1, the spreading claws 3 can be slowly stretched along the transitional curved surface, and the resistance received is small and the curved surface is designed to support The stretching of the claws (3) has a guiding effect, preventing the stretching claws 3 from stretching in other directions to damage the structure and further damage the abdominal wall. As shown in Figure 3, when the moving sleeve 2 moves upward along the main rod 1, the spreading claws 3 are brought together along the transition surface under the drive of the hinged rod 4, and the size of the hinged rod 4 is the same as the straight groove 32 opened at the lower end of the spreading claws 3. Anastomosis, the stretching claw 3 can be accommodated in the straight groove 32 of the hinged rod 4, so that it is completely close to the base, the diameter is reduced to a minimum, and it is convenient to withdraw from the abdomen.
需要说明的是，底座5上的直槽孔51与铰接杆4末端的限位孔41相铰接，直槽孔51的设计使整体增加了一个自由度，使得铰接杆4可以沿着它进行小幅度的上下移动，进而使撑开爪3能够撑开到最大角度，并在撑开到最大角度后在直槽孔51的两端阻挡作用和腹腔压力下维持撑开这一动作。而更优的是，在撑开的过程中，由于直槽孔51的顶部与撑开爪3的下端面进行限位，使撑开爪 3仅能撑开成水平位置，进一步起到安全的作用。It should be noted that the straight slot 51 on the base 5 is hinged to the limit hole 41 at the end of the hinge rod 4, and the design of the straight slot 51 adds a degree of freedom to the whole, so that the hinge rod 4 can carry out small movements along it. The amplitude moves up and down, and then the claws 3 can be stretched to the maximum angle, and the action of stretching is maintained under the blocking effect of the two ends of the straight slot 51 and the pressure of the abdominal cavity after stretching to the maximum angle. And more preferably, in the process of stretching, since the top of the straight slot 51 and the lower end surface of the stretching claw 3 are limited, the stretching claw 3 can only be stretched into a horizontal position, further playing a role in safety. effect.
以上所揭露的仅为本发明一种较佳实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属本发明所涵盖的范围。The above disclosure is only a preferred embodiment of the present invention, which certainly cannot limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
