技术领域technical field
本发明属于医疗器械领域，具体涉及一种用于气管的异物钳结构。The invention belongs to the field of medical instruments, and in particular relates to a structure of foreign body forceps for trachea.
背景技术Background technique
异物被误吸入呼吸道之后会妨碍呼吸，严重时会导致窒息甚至死亡，吸入异物后必须及时取出。通常异物取出是使用气管镜配合气管异物钳进行操作，现有技术的异物钳都是金属材质，经过清洗消毒后多次重复使用，但异物钳的钳爪部位通常与钳体主体是铰接形式连接，连接位置存在死角，难以彻底清洗干净，重复使用时存在感染风险，使用效果不理想。而金属材质的异物钳若是一次性使用又成本过高且浪费资源。申请人于2014年9月21日申请的名称为：一种气管异物钳及钳体，申请号为：2014104843355的专利申请解决了上述问题，然该种异物钳的钳体在夹取异物时钳爪在钳体的前方张开，夹取某些不规则形状且体积较大甚至带有尖刺的异物时不能完全将异物包裹起来，在夹紧异物后向外拖拽的过程中容易伤及患者组织，使用效果不理想。Foreign objects that are accidentally inhaled into the respiratory tract will hinder breathing, and in severe cases, it will cause suffocation or even death. After inhaling foreign objects, they must be removed in time. Usually, foreign body removal is performed by using a bronchoscope with tracheal foreign body forceps. The foreign body forceps in the prior art are made of metal, and are reused many times after cleaning and disinfection. However, the jaws of the foreign body forceps are usually connected to the main body of the forceps in a hinged form. , There is a dead angle in the connection position, it is difficult to clean thoroughly, there is a risk of infection when it is reused, and the use effect is not ideal. However, if the foreign body forceps made of metal are used once, the cost is too high and resources are wasted. The name of the applicant's application on September 21, 2014 is: a tracheal foreign body forceps and forceps body, the patent application number is: 2014104843355 solves the above problems, but the forceps body of this foreign body forceps clamps The claws are opened in front of the pliers body, and when grasping certain irregularly shaped, large-sized or even spiked foreign objects, they cannot completely wrap up the foreign objects, and it is easy to injure them during the process of clamping the foreign objects and dragging them outward. Patient tissue, the use effect is not ideal.

The following two actions respectively produce two actions. When the jaws are opened to align with the foreign matter and make the foreign matter within the range of the capsule, the support tube and the telescopic tube lose support after the piston rod returns to the initial state, and the jaw returns to the original size, and the foreign matter is released. It is completely wrapped in the capsule body, and the foreign matter will not fall out during the process of pulling out the forceps body, which is safe and convenient to use. The adjusting nut on the pneumatic control handle can adjust the advancing range of the piston rod. The adjusting nut can be adjusted to an appropriate position in advance according to the size of the foreign object and the size of the foreign object position space, so that the piston rod can be pressed to the bottom at one time when clamping the foreign object. That is to say, the size of the jaw is appropriate, which is beneficial to shorten the operation time and relieve the pain of the patient. The foreign body net pliers are suitable for taking out foreign bodies in various positions in the body. The annular ribs on the inner wall of the telescopic tube make the telescopic tube stretch in the axial direction, while the radial bulge is small, which can ensure that the telescopic tube will not cause The body volume of the forceps becomes too large. The size of the pliers body can be processed into different sizes to suit different parts.

The piston is connected with a piston rod 13 whose end extends out of the piston cylinder. The end of the piston rod away from the piston is formed with a threaded connection part 132. , an adjusting nut 12 is connected to the threaded connection part of the piston rod, and a push ring 131 is integrally connected to the rear end of the piston rod; The outer wall of the end is integrally connected with two symmetrically arranged pull rings 112, the pliers body is integrally formed by elastic rubber material, the pliers body 3 is integrally formed by elastic rubber material, and the pliers body is formed by an ellipsoidal capsule Body 32 and a round tubular pipe joint b31 integrally connected to one end of the long axis direction of the capsule body, the pipe joint b is connected with the connecting pipe; the capsule body is a hollow structure, and A circular clamp 35 is formed on the wall at the other end, the diameter of the clamp is smaller than the length of the short axis of the capsule; a telescopic tube 33 is formed on the inner periphery of the clamp, and the inner wall of the capsule is uniform along the long axis. A plurality of support tubes 34 are formed; the end of each support tube away from the pipe joint b is connected with the telescopic tube, and the end of each support tube close to the pipe joint b is connected and communicated with the pipe joint b; the thickness of the telescopic tube is less than that of the support tube thickness, and the inner wall of the telescopic tube is evenly formed with annular ribs; the piston rod pushes the piston to move to the front end of the piston tube to compress the air in the piston tube, and the compressed air enters the support tube and the telescopic tube through the connecting tube, and the support tube is subjected to air pressure The function supports the capsule to make it in the unfolded state, and the telescopic tube is stretched by the air pressure to make the jaw widen. After the piston rod returns to the original state, the support tube and the telescopic tube lose their support, and the jaw returns to the original size.
所述的钳体通过3D打印一次性加工成型。所述伸缩管内壁相邻两个筋条之间的间距为伸缩管内径的1/10-1/5，筋条的径向截面呈半圆形。相邻筋条之间的间距较小，使伸缩管受气压驱动后在径向产生的形变量微小。The pliers body is processed and formed at one time by 3D printing. The distance between two adjacent ribs on the inner wall of the telescopic tube is 1/10-1/5 of the inner diameter of the telescopic tube, and the radial cross-section of the ribs is semicircular. The distance between the adjacent ribs is small, so that the radial deformation of the telescopic tube after being driven by the air pressure is small.
使用时，将纤维内窥镜连同钳体及连接管伸入患者体内患处异物附近位置，通过纤维内窥镜观察，使夹口对准异物；按压活塞杆使气动控制手柄产生气压，钳体的支撑管在气压作用下变硬，从而起到支撑囊体的作用，所述伸缩管在气压作用下伸长，从而使夹口张大，微调钳体的位置使夹口对准异物并使异物处于夹口内侧后，只要松开活塞杆，伸缩管失去气压作用恢复初始形状，异物便被包裹在囊体之中，随后将钳体连同连接管拉出即可取出异物。When in use, insert the fiber endoscope together with the clamp body and the connecting tube into the position near the foreign body in the patient's body, observe through the fiber endoscope, and align the jaws with the foreign body; press the piston rod to make the pneumatic control handle generate air pressure, and the clamp body The support tube hardens under the action of air pressure, thereby playing the role of supporting the capsule, and the telescopic tube is stretched under the action of air pressure, so that the jaws are expanded, and the position of the pliers body is fine-tuned so that the jaws are aligned with the foreign matter and the foreign matter is in the After the inside of the clamp, as long as the piston rod is released, the telescopic tube loses the air pressure and returns to its original shape, and the foreign matter is wrapped in the capsule, and then the pliers and the connecting tube are pulled out to remove the foreign matter.
实施例2Example 2
本实施例与实施例1的区别特征在于：所述的伸缩管成型在囊体外壁，支撑管与伸缩管相连的一端透过囊体与伸缩管相连通。这样既能保证伸缩管能够带动夹口张大，同时避免伸缩管充气伸长状态时被异物上可能存在的尖刺刺破而损坏。The difference between this embodiment and Embodiment 1 is that the telescopic tube is formed on the outer wall of the capsule, and the end of the support tube connected to the telescopic tube communicates with the telescopic tube through the capsule. This can not only ensure that the telescopic tube can drive the clamp to expand, but also prevent the telescopic tube from being punctured and damaged by the possible thorns on the foreign matter when it is inflated and stretched.
