Description

Technical Field

[0001] This utility model relates to the field of fixation device technology, and in particular to a detachable finger tendon fixation device. Background Technology

[0002] Finger tendon injury is a common trauma to the hand, often caused by external forces such as cuts, crush injuries, and lacerations, or by long-term overuse. In the field of hand surgery, finger tendon injury is a common type of trauma, and its fixation after repair directly affects tendon healing and the recovery of the patient's hand function. Traditional finger tendon fixation often uses plaster casts or hard plastic splints.

[0003] Traditional finger tendon fixation devices have poor breathability, and prolonged wear can easily lead to pressure sores and allergies on the patient's skin. Furthermore, they need to be completely removed during postoperative dressing changes and wound observation, which can easily affect tendon stability or even cause secondary damage if not handled properly.

[0004] Therefore, to address the shortcomings of traditional finger tendon fixation methods, a detachable finger tendon fixation device can be designed. Through the coordinated design of components such as a breathable support sleeve, sponge pad, medical canvas protective sleeve, and wristband, efficient fixation and comfortable care can be achieved, thereby facilitating the solution of the aforementioned problems. Utility Model Content

[0005] To overcome the shortcomings of traditional finger tendon fixation devices, such as the tendency for prolonged wear to cause pressure sores and allergies, and the need for complete removal during postoperative dressing changes and observation, which can easily lead to secondary damage, this invention provides a detachable finger tendon fixation device.

[0006] The technical solution is as follows: A detachable finger tendon fixation device includes a breathable support sleeve, a sponge pad, a medical canvas protective sleeve, and a wristband; the breathable support sleeve has a fixing cavity inside, and a sponge pad for cushioning the finger is arranged sequentially inside the fixing cavity. A sterile dressing pad for applying medication to the patient's finger is fitted inside the sponge pad. The outer end of the breathable support sleeve is provided with a medical canvas protective sleeve for resisting external bacteria, and the front end of the breathable support sleeve is provided with a wristband for connecting and fixing the patient's wrist.

[0007] Furthermore, an opening is provided on one side of the breathable support sleeve, and multiple sets of elastic adhesive tapes are linearly arranged above the opening, while adhesive seats corresponding to the elastic adhesive tapes are attached to the bottom of the opening.

[0008] Furthermore, the rear end of the breathable support sleeve is equipped with a fingertip sleeve, and the center of the fingertip sleeve has a Kirschner wire interface, with a silicone sealing ring inside the Kirschner wire interface.

[0009] Furthermore, a flexible connecting strip is provided between the fingertip sleeve and the breathable support sleeve, and the fingertip sleeve and the breathable support sleeve are connected by the flexible connecting strip.

[0010] Furthermore, the inner wall of the breathable support sleeve is surrounded by multiple shaping grooves, and each of the shaping grooves is equipped with an aluminum alloy arc-shaped support strip that conforms to the curve of the finger.

[0011] Furthermore, a connecting block is provided above the outer front end of the breathable support sleeve, a buckle is provided at the front end of the connecting block, an elastic band is provided between the connecting block and the buckle, and the connecting block and the buckle are connected by the elastic band.

[0012] Furthermore, both sides of the wristband are equipped with wrist connecting straps, and the opposite sides of the two sets of wrist connecting straps are equipped with adhesive strips to connect the two sets of wrist connecting straps. The center of the end of the wristband near the breathable support sleeve is equipped with a corresponding buckle socket.

[0013] Furthermore, the medical canvas protective cover has a pre-drilled hole at the center of its rear end corresponding to the Kirschner wire interface, and multiple sets of buffer rings are linearly fitted at the outer end of the medical canvas protective cover.

[0014] The beneficial effects are significant. Compared to traditional finger tendon fixation devices, this device offers substantial advantages. During postoperative dressing changes, traditional devices require complete removal, which can easily affect tendon stability or even cause secondary damage due to improper operation. This device, however, utilizes an opening in the breathable support sleeve and an elastic bandage design to allow for localized dressing changes, avoiding adverse effects on the tendon. Regarding wearing comfort, traditional devices have poor breathability, and prolonged wear can easily cause pressure sores and allergies on the patient's skin. The breathable support sleeve, sponge pad, and medical canvas protective sleeve of this device are all relatively breathable, effectively solving this problem. Furthermore, the collaborative design of the various components of this device, such as the wristband and breathable support sleeve connected by buckles, sockets, and elastic bands, allows for flexible adjustment to adapt to different patients' hand sizes and activity needs. While ensuring effective fixation, it improves patient comfort and convenience, providing superior nursing care for the rehabilitation of patients with finger tendon injuries.

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] In the field of hand surgery, the fixation after repairing finger tendon injuries is crucial to the treatment outcome. Tendon healing is a complex physiological process that generally involves three stages: inflammation, proliferation, and remodeling. The entire process typically lasts 6-8 weeks. During this period, stable and scientific fixation provides a good healing environment for the tendon, preventing re-rupture or misalignment due to excessive activity. At the same time, proper fixation can promote local blood circulation, accelerate the delivery of nutrients and the removal of metabolic waste, which is beneficial for the repair and regeneration of tendon cells. Improper fixation can not only prolong the healing time but may also lead to complications such as tendon adhesions and joint stiffness, seriously affecting the recovery of the patient's hand function and even causing permanent functional impairment.

[0023] Traditional methods of immobilizing finger tendons mainly use plaster casts or rigid plastic splints. Plaster casts have the advantages of low cost and good shapeability, and can be customized according to the patient's hand shape. However, their drawbacks are also very obvious. First, plaster casts have extremely poor breathability. After wearing them for a long time, the patient's skin is in a hot and humid environment, and sweat cannot evaporate in time. This creates favorable conditions for bacterial growth, which can easily lead to skin inflammation, pressure sores, allergies, and other problems. Clinical observations have found that about 35% of patients who used plaster casts for more than 2 weeks developed varying degrees of skin itching, erythema, and other allergic symptoms, and 10% developed pressure sores. Second, during postoperative dressing changes and wound observation, because the plaster cast is a whole fixation, it needs to be removed with professional tools. The operation is complicated and risky. If the operation is not done properly, such as using too much force during removal, it may pull on the tendon that has not yet fully healed, affecting the stability of the tendon, or even causing secondary injury.

[0024] Compared to plaster casts, rigid plastic splints offer some improvements in weight and hardness, but they also present several problems. Their hard material lacks cushioning, and prolonged wear can put significant pressure on the skin, especially around bony prominences, easily causing pressure marks, hindering local blood circulation, and increasing the likelihood of pressure sores. Furthermore, the fixation method of rigid plastic splints is relatively limited, making it difficult to adapt to individual differences in patients' hands and limiting their fixation effectiveness. Postoperative care also requires complete removal, preventing localized procedures, which undoubtedly increases the difficulty of care and the risk of tendon injury.

[0025] Example

[0026] like Figures 1-5 As shown, a detachable finger tendon fixation device includes a breathable support sleeve 1, a sponge pad 2, a medical canvas protective sleeve 4, and a wristband 5. The breathable support sleeve 1 has a fixing cavity 3 inside, and the sponge pad 2 for cushioning the finger is arranged sequentially inside the fixing cavity 3. A sterile dressing pad 6 for applying medication to the patient's finger is attached to the inside of the sponge pad 2. The outer end of the breathable support sleeve 1 is provided with a medical canvas protective sleeve 4 for resisting external bacteria, and the front end of the breathable support sleeve 1 is provided with a wristband 5 for connecting and fixing the patient's wrist.

[0027] An opening 7 is provided on one side of the breathable support sleeve 1. Multiple sets of elastic adhesive strips 8 are linearly arranged above the opening 7, and adhesive seats 9 corresponding to the elastic adhesive strips 8 are attached to the bottom of the opening 7. The breathable support sleeve 1 can be flexibly opened and closed through the opening 7. Through the cooperation of the elastic adhesive strips 8 and the adhesive seats 9, it can be flexibly adjusted according to the thickness of the patient's fingers to ensure the fit and fixation effect of the fixation device.

[0028] The rear end of the breathable support sleeve 1 is provided with a fingertip sleeve 12. The center of the fingertip sleeve 12 is provided with a Kirschner wire interface 14. The Kirschner wire interface 14 is provided with a silicone sealing ring. The Kirschner wire interface 14 facilitates the accurate installation of Kirschner wires when they need to be fixed. The internal silicone sealing ring plays a role in sealing and anti-slip, ensuring that the Kirschner wires are stable and do not loosen after installation, while preventing external bacteria, dust and other contaminants from entering.

[0029] A flexible connecting strap 13 is provided between the fingertip sleeve 12 and the breathable support sleeve 1. The fingertip sleeve 12 and the breathable support sleeve 1 are connected by the flexible connecting strap 13, so that the fingertip sleeve 12 can be removed when needed.

[0030] The inner wall of the breathable support sleeve 1 is surrounded by multiple sets of shaping grooves 10. Each of the shaping grooves 10 has an aluminum alloy arc-shaped support strip 11 that conforms to the curve of the finger. By conforming to the curve of the finger, the aluminum alloy arc-shaped support strip 11 can provide stable and ergonomic support for the finger, effectively fix the finger position, prevent tendon dislocation caused by accidental finger movement, and promote tendon healing. At the same time, the shaping grooves 10 fix the aluminum alloy arc-shaped support strip 11 in a proper position, ensuring the support effect while avoiding the support strip shifting and causing discomfort to the patient.

[0031] A connecting block 15 is provided on the upper part of the outer front end of the breathable support sleeve 1. A buckle 17 is provided at the front end of the connecting block 15. An elastic band 16 is provided between the connecting block 15 and the buckle 17. The connecting block 15 and the buckle 17 are connected by the elastic band 16. Through the combination of the connecting block 15, the buckle 17 and the elastic band 16, the connection between the fixing device and the wristband 5 is more convenient and secure. The elastic band 16 has a certain degree of elasticity and can adapt to different movement states of the patient's wrist. While ensuring the fixing effect, it reduces the feeling of restraint on the wrist and improves the wearing comfort. The buckle 17 is designed to facilitate quick connection and disassembly, making it easy for the patient to put on and adjust it by themselves.

[0032] Both sides of the wristband 5 are provided with wrist connecting straps 18. The opposite sides of the two sets of wrist connecting straps 18 are provided with adhesive strips 19 to connect the two sets of wrist connecting straps 18. The center of the end of the wristband 5 near the breathable support sleeve 1 is provided with a socket 20 corresponding to the buckle 17. Through the design of the wrist connecting straps 18 and adhesive strips 19, it can be freely adjusted according to the thickness of the patient's wrist to ensure that the wristband 5 fits tightly with the wrist and provides a stable fixation effect. The connection between the breathable support sleeve 1 and the wristband 5 is secure through the cooperation of the socket 20 and the buckle 17.

[0033] The medical canvas protective sleeve 4 has a reserved hole 21 at the center of its rear end corresponding to the Kirschner wire interface 14. Multiple sets of buffer rings 22 are linearly fitted on the outer end of the medical canvas protective sleeve 4. The reserved hole 21 corresponds to the Kirschner wire interface 14, which does not affect the use of the Kirschner wire. At the same time, it ensures that the medical canvas protective sleeve 4 can completely cover the breathable support sleeve 1, which can play a role in resisting external bacteria. The buffer rings 22 at the outer end can effectively buffer external impact force, reduce the impact of external force on the injured part of the finger, provide extra protection for the finger, and reduce the possibility of secondary injury.

[0034] During the procedure, the nurse first unfastens the elastic band 8 at the opening 7 of the breathable support sleeve 1, opening the breathable support sleeve 1 from the opening 7. Due to the design of the elastic band 8 and the adhesive seat 9, the unfastening process will not cause additional pulling on the patient's fingers. After opening, the nurse can directly observe the sterile dressing pad 6 inside and the patient's wound condition. Then, the sterile dressing pad 6 is replaced. After changing the dressing, the nurse closes the breathable support sleeve 1 again. According to the thickness of Mr. Wang's index finger, the nurse flexibly adjusts the fit using the elastic band 8 and the adhesive seat 9 to ensure that the fixation device fits the finger tightly. Next, the nurse inserts the buckle 17 at the front end of the breathable support sleeve 1 into the socket 20 of the wristband 5. Using the connecting block 15, the buckle 17, and the elastic band 16, the fixation device is quickly and firmly connected to the wristband 5. Finally, by adjusting the adhesive strips 19 of the wrist connecting straps 18 on both sides of the wristband 5 according to the thickness of Mr. Wang's wrist, the wristband 5 is made to fit the wrist tightly, completing the wearing of the entire fixation device.

[0035] Its working principle is as follows: During the fixation process, the aluminum alloy arc-shaped support strip 11 in the shaping groove 10 of the inner wall of the breathable support sleeve 1 conforms to the curve of the finger, providing stable and ergonomic support for the finger, fixing the finger in a proper position, preventing tendon dislocation due to accidental activity, and promoting tendon healing. When Kirschner wire fixation is required, the doctor can accurately install the Kirschner wire through the Kirschner wire interface 14 in the center of the fingertip sleeve 12. The silicone sealing ring inside the interface provides sealing and anti-slip functions, ensuring that the Kirschner wire is stable and does not loosen, while preventing external bacteria and dust from entering. The buffer ring 22 at the outer end of the medical canvas protective sleeve 4 can effectively buffer external impact during daily activities, reducing the impact of external forces on the injured part of the finger and reducing the risk of secondary injury. The material characteristics of the breathable support sleeve 1 and the sponge pad 2 ensure good breathability of the device, reducing the probability of skin pressure sores and allergies.

[0036] Its beneficial effects are significant. Compared with traditional finger tendon fixation devices, this device has significant advantages. In the postoperative dressing change process, traditional devices need to be completely removed, which can easily affect tendon stability or even cause secondary damage due to improper operation. However, this device, through the opening 7 of the breathable support sleeve 1 and the design of the elastic adhesive band 8, allows for local opening and dressing change, avoiding adverse effects on the tendon. In terms of wearing comfort, traditional devices have poor breathability, which can easily cause pressure sores and allergies to the patient's skin after prolonged wear. The breathable support sleeve 1, sponge pad 2, and medical canvas protective sleeve 4 of this device are all relatively breathable, effectively solving this problem. In addition, the components of this device are designed in a coordinated manner. For example, the wristband 5 is connected to the breathable support sleeve 1 through the buckle 17, socket 20, and elastic band 16, which can be flexibly adjusted to adapt to the hand size and activity needs of different patients. While ensuring the fixation effect, it improves the comfort and convenience of wearing the device, providing better nursing care for the rehabilitation of patients with finger tendon injuries.
