Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical apparatus and instruments, and particularly relates to a severed finger fixing auxiliary device. BACKGROUND

[0002] Severed finger replantation is a technique for reattaching a completely or incompletely severed finger through microsurgical technology, and the surgery usually includes steps such as debridement, vascular anastomosis, bone fixation, tendon and nerve repair, and aims to make the severed finger survive and restore function as much as possible. In order to prevent the severed finger from being displaced, a Kirschner wire is used to fix the interphalangeal joint, and since the vascular anastomosis is a long-time fine operation performed by using a thin suture, the severed finger part is lifted, which is beneficial to the observation and suture of the blood vessels, and thus the suture work difficulty is reduced. However, since the Kirschner wire is currently used to fix the interphalangeal joint, the support and lifting of the severed finger part are prone to displacement, which in turn reduces the success rate of the severed finger replantation. Therefore, a fixing auxiliary device should be used to strengthen the fixation of the severed finger, and the existing fixing auxiliary device is difficult to meet the fixation requirements of the severed finger of different patients. SUMMARY

[0003] The utility model solves the technical problem to provide a severed finger fixing auxiliary device, in order to lift the severed finger and stably fix it, and meet the severed finger fixation requirements of different patients.

[0004] In order to solve the above problems, the utility model adopts the following technical scheme:

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further described in detail below by combining with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0017] As Figure 1 and Figure 2As shown, the finger fixation auxiliary device of the embodiment comprises an arm support assembly for supporting an arm and a finger fixation clamp 9 for clamping a severed finger, and a universal hose 8 is arranged between the arm support assembly and the finger fixation clamp 9. The universal hose 8 is a composite metal pipe covered by a metal spring steel wire, can be arbitrarily bent into a certain shape in a three-dimensional space and can maintain the shape. One end of the universal hose 8 is connected with the arm support assembly, and the other end of the universal hose 8 is connected with the finger fixation clamp 9. The finger fixation clamp 9 comprises a first clamp body 91 and a second clamp body 92. The second clamp body 92 is fixed with the universal hose 8. The middle part of the second clamp body 92 is rotatably connected with the first clamp body 91. The finger fixation clamp 9 can clamp and fix the severed finger, increase the stability of the severed finger, and the bending of the universal hose 8 can correspondingly adjust the position angle of the finger fixation clamp 9 to adapt to the fixation of different severed finger parts.

[0018] The finger fixation clamp 9 is suitable for clamping and fixing the severed finger, has a certain stability, and is not easy to press the severed finger. A first finger groove 93 is arranged at the front end of the first clamp body 91, and a second finger groove 94 is arranged at the front end of the second clamp body 92. The first finger groove 93 and the second finger groove 94 are opposite to each other, and the severed finger can be clamped between the first finger groove 93 and the second finger groove 94.

[0019] The arm support assembly comprises a first support bracket 1 supporting a large arm and a second support bracket 2 supporting a forearm. One end of the first support bracket 1 is hingedly connected with one end of the second support bracket 2. The lower end of the second support bracket 2 is hingedly connected with a support piece 7. The first support bracket 1 is provided with a positioning part 5 extending below the second support bracket 2. The positioning part 5 is provided with a plurality of positioning grooves 6 arranged along the length direction. The support piece 7 can be rotatably clamped into any one of the positioning grooves 6 to fix the angle between the first support bracket 1 and the second support bracket 2.

[0020] The first support bracket 1 and the second support bracket 2 comprise a hard outer shell 4 and a soft inner pad 3. The inner pad 3 is fixed inside the outer shell 4. The inner pad 3 supports the arm of the patient, and the support is more comfortable. The hinge connection between the first support bracket 1 and the second support bracket 2 is actually a hinge connection between the outer shells 4. A hinge shaft is arranged on the outer shell 4 of the second support bracket 2, and a hinge hole is arranged on the outer shell 4 of the first support bracket 1. The hinge shaft and the hinge hole are matched to realize the hinge connection.

[0021] In use, the finger fixation clamp 9 is clamped at the position of the severed finger by bending the universal hose 8, thereby strengthening the fixation of the severed finger and preventing the displacement of the severed finger. Then, the support piece 7 is inserted into different positioning grooves 6, so that the first support bracket 1 is rotated at a certain angle with respect to the second support bracket 2. The first support bracket 1 supports the forearm of the patient, and the second support bracket 2 supports the large arm of the patient. The forearm and the severed finger of the patient are lifted to facilitate the anastomosis of the severed finger.

[0022] The above merely is the preferred embodiment of the present application, and does not limit the present application, and any modification, equivalent replacement and improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
