Description

Translated fromChinese
一种带拉力调节器的骨钉牵引装置A bone nail traction device with a tension adjuster

技术领域Technical field

本实用新型属于医疗用品技术领域,具体涉及一种带拉力调节器的骨钉牵引装置。The utility model belongs to the technical field of medical supplies, and specifically relates to a bone nail traction device with a tension adjuster.

背景技术Background technique

一般患者的四肢出现骨折以后,骨折端移位较为明显,在手术之前通常需要进行骨牵引,也就是在骨折的两端或一端穿入一个骨钉,然后再用重物将患肢进行牵引以达到骨折复位,减轻局部的疼痛和出血,为手术准备,重物目前使用较多的为秤砣;Generally, after a patient's limbs are fractured, the fracture ends are more obviously displaced. Bone traction is usually required before surgery, that is, a bone nail is inserted into both ends or one end of the fracture, and then the affected limb is traction with heavy objects. To achieve fracture reduction, reduce local pain and bleeding, and prepare for surgery, the most commonly used heavy objects are weights;

现有技术针对骨钉牵引使用秤砣作为牵引重物会存在以下技术弊端,例如,专利号CN215739730U公开的一种用于骨牵引秤砣的悬挂装置,其指出秤砣一般置于床边,易受到来往人碰撞产生摇晃,影响牵引效果等,另外,秤砣牵引提供的拉力取决于秤砣的重量,因此,医护人员根据患者情况需要准备多种规格的秤砣以备使用,难以收纳的同时针对牵引拉力的调节操作也较为麻烦,因此,采用秤砣作为牵引重物的使用效果欠佳。The existing technology using weights as traction weights for bone nail traction has the following technical disadvantages. For example, the patent number CN215739730U discloses a suspension device for bone traction weights, which points out that the weights are generally placed beside the bed and are easily affected by people coming and going. The collision will cause shaking, affecting the traction effect, etc. In addition, the pulling force provided by the weight for traction depends on the weight of the weight. Therefore, medical staff need to prepare various specifications of weights for use according to the patient's condition. It is difficult to store and adjust the traction force at the same time. It is also more troublesome. Therefore, the use of weights as a traction heavy object is not effective.

That is, in order to facilitate the operation of medical staff, the driving member 57 can also be configured to drive the motor to automatically control the rotation of the screw 52.

实施例2Example 2

在实施例1的基础上,如图2所示,所述U型牵引架2与骨钉体1的连接处设有无拉力报警结构6,无拉力报警结构6可以监测U型牵引架2与骨钉体1处的是否存在压力并进行无压力时的报警,提醒医护人员注意,所述无拉力报警结构6包括外壳61,所述外壳61上设有通槽并且通槽内活动插接有固定套62,所述固定套62用于固定骨钉体1,所述固定套62的一侧与U型牵引架2相连接,所述外壳61的内部还设有电池67、导电座65和报警器66,所述导电座65通过线缆与电池67连接,所述固定套62不与U型牵引架2的一端设有通过线缆与报警器66连接的端子座68,所述端子座68与导电座65接触后使得报警器66与电池67之间的线路得以连通,所述固定套62靠近U型牵引架2的一侧设有外壳61相插接的推杆63,所述推杆63的外侧套设有与外壳61相连接的拉伸弹簧64,所述外壳61远离电池67的一端设有供固定套62卡接的卡套69。On the basis of Embodiment 1, as shown in Figure 2, a no-tension alarm structure 6 is provided at the connection between the U-shaped traction frame 2 and the bone nail body 1. The no-tension alarm structure 6 can monitor the relationship between the U-shaped traction frame 2 and the bone nail body 1. Whether there is pressure at the bone nail body 1 and perform an alarm when there is no pressure, remind medical staff to pay attention. The no-tension alarm structure 6 includes a shell 61. The shell 61 is provided with a through slot and there are movable plugs in the through slot. Fixed sleeve 62. The fixed sleeve 62 is used to fix the bone nail body 1. One side of the fixed sleeve 62 is connected to the U-shaped traction frame 2. The inside of the outer shell 61 is also provided with a battery 67, a conductive base 65 and Alarm 66, the conductive base 65 is connected to the battery 67 through a cable, and one end of the fixed sleeve 62 that is not connected to the U-shaped traction frame 2 is provided with a terminal base 68 connected to the alarm 66 through a cable. The terminal base 68 is in contact with the conductive seat 65 so that the circuit between the alarm 66 and the battery 67 is connected. The fixed sleeve 62 is provided with a push rod 63 on the side close to the U-shaped traction frame 2 and the shell 61 is plugged into it. The outer side of the rod 63 is provided with a tension spring 64 connected to the housing 61 .

无拉力报警结构6具体应用时,当U型牵引架2受到来自牵引绳3的牵引时,固定套62在U型牵引架2的牵引下会相对于外壳61产生移动,致使其外侧的推杆63与外壳61产生相对位移致使推杆63外侧与外壳61相连接的拉伸弹簧64产生拉伸,此时,固定套62另一侧上的端子座68与导电座65脱离连接,报警器66与电池67之间的电路处于断开状态,报警器66(报警器66可以选择灯光、声音或者声光报警)不动作,若U型牵引架2处受到的压力消失后,固定套62在拉伸弹簧64的弹力作用下复位,此时,固定套62上的端子座68与导电座65接触,报警器66与电池67之间的电路联动,报警器66产生动作进行相应的报警,用以提醒医护人员,另外,U型牵引架2不使用时,可将无拉力报警结构6的固定套62移动至与卡套69相插接,即可保证固定套62上的端子座68与导电座65不接触,报警器66不产生动作,使用时将固定套62从卡套69中推出即可;When the no-tension alarm structure 6 is specifically applied, when the U-shaped traction frame 2 is pulled by the traction rope 3, the fixed sleeve 62 will move relative to the outer shell 61 under the traction of the U-shaped traction frame 2, causing the push rod on its outer side to move. The relative displacement between 63 and the housing 61 causes the tension spring 64 connected to the housing 61 on the outside of the push rod 63 to stretch. At this time, the terminal block 68 on the other side of the fixed sleeve 62 is disconnected from the conductive block 65, and the alarm 66 The circuit with the battery 67 is in a disconnected state, and the alarm 66 (the alarm 66 can select light, sound or sound and light alarm) does not operate. If the pressure on the U-shaped traction frame 2 disappears, the fixed sleeve 62 will It is reset under the elastic force of the extension spring 64. At this time, the terminal base 68 on the fixed sleeve 62 is in contact with the conductive base 65. The circuit between the alarm 66 and the battery 67 is linked, and the alarm 66 acts to perform a corresponding alarm. Medical staff are reminded that in addition, when the U-shaped traction frame 2 is not in use, the fixed sleeve 62 of the non-tension alarm structure 6 can be moved to be plugged into the ferrule 69 to ensure that the terminal block 68 on the fixed sleeve 62 is connected to the conductive seat. 65 is not in contact, the alarm 66 will not act, just push the fixed sleeve 62 out of the ferrule 69 when in use;

无拉力报警结构6的设置可以用于U型牵引架2与骨钉体1连接处处于异常无拉力牵引下的应急报警,可以提醒医护人员及时应对处理,使用效果好。The setting of the no-tension alarm structure 6 can be used for emergency alarm when the connection between the U-shaped traction frame 2 and the bone nail body 1 is under abnormal no-tension traction, and can remind medical staff to respond in time, and the use effect is good.
