Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically an emergency fixation device for fractures in emergency surgery. Background Technology

[0002] In clinical practice of emergency surgery, effective fixation of limb fractures is one of the core aspects of trauma emergency treatment. Timely fracture fixation can effectively relieve severe pain, avoid secondary damage caused by movement of the fracture ends, control bleeding, stabilize local blood vessels, prevent fracture complications, and create safe and stable conditions for subsequent imaging examinations, transportation, and definitive treatment.

[0003] Traditional temporary fixation methods typically employ splints or traction fixation. However, these methods cannot fully guarantee the stability of the fracture site and are prone to causing secondary damage due to movement during transfer. Traction fixation, on the other hand, is complex to operate and can easily lead to missed opportunities for optimal fixation in emergency situations, thus delaying treatment. Therefore, there is an urgent need for an emergency surgical fracture fixation device to address these technical issues. Summary of the Invention

[0004] The purpose of this invention is to provide a technical solution for an emergency fixation device for fractures in emergency surgery, in order to solve the problem that traditional fixation methods proposed in the prior art cannot fully guarantee the stability of the fracture site and are prone to secondary damage to the fracture site due to shaking during the transfer process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an emergency surgical fracture fixation device, comprising a plurality of arc-shaped splicing parts, wherein one side of each arc-shaped splicing part is provided as an insertion part and the other side is provided as an adjustment part; The insertion part of one arc-shaped splicing component is inserted into the adjustment part of another arc-shaped splicing component to complete the connection of any two arc-shaped splicing components, and the insertion part can slide inside the adjustment part; Several of the aforementioned arc-shaped splicing pieces are connected to form a fixation tube for fixing the fracture site, and the fixation tube is fastened on the outside by straps.

[0006] According to the above technical solution, a fixation cylinder is formed by splicing several arc-shaped splicing parts to quickly fix the fracture sites of the patient's limbs, which can effectively improve the fixation efficiency of the fracture sites. At the same time, by splicing different numbers of arc-shaped splicing parts, it can be adapted to patients of different body types, which can effectively improve the applicability of the fixation device.

[0007] Preferably, the plug-in part includes a plug-in plate and a plug connector. One end of the plug-in plate is connected to an arc-shaped splicing piece, and the other end is provided with a plug connector. The cross-section of the plug connector is triangular. The adjusting part includes an adjusting groove, the cross-section of which is triangular; The connector is inserted into the adjustment slot and is compatible with the adjustment slot.

[0008] According to the above technical solution, the quick assembly of the fixing device can be achieved through the interconnection of the connector and the adjustment groove, and the arbitrary assembly performance of the entire fixing device is enhanced, thereby improving the adaptability of the fixing device.

[0009] Preferably, the depth of the adjustment groove is greater than the length of the connector, and the width of the connector end is equal to the width of the adjustment groove end. When the connector slides inside the adjustment groove, the adjustment groove widens due to the squeezing force of the connector.

[0010] According to the above technical solution, after the fixation device is assembled, the inner diameter of the fixation device can be adjusted to adapt to the patient's limbs. Furthermore, during the fine-tuning process, the tightness of the fixation on the patient's fracture site can be further improved, preventing displacement of the fracture site and causing secondary injury.

[0011] Preferably, the inner wall of the adjustment groove is symmetrically provided with a number of limiting grooves for fixing the position of the connector.

[0012] According to the above technical solution, the design of the limiting groove can stabilize the inner diameter after the inner diameter of the fixation device is finely adjusted, so as to avoid loosening and affecting the fixation of the patient's fracture site.

[0013] Preferably, a deformation part is provided on the inner side of the arc-shaped splice on one side of the adjustment groove, and a tolerance groove is provided at the connection between the deformation part and the arc-shaped splice to provide deformation space for the deformation part.

[0014] According to the above technical solution, the design of the deformable part provides space for the connector to slide inside the adjustment groove, so that the inner diameter of the fixing device can be finely adjusted. In order to ensure that the deformable part fits the patient's skin tissue as closely as possible after deformation, a tolerance groove is designed to provide tolerance space for the deformation of the deformable part.

[0015] Preferably, the deformable part has an arc-shaped concave portion on the side away from the adjustment groove for conforming to the patient's skin, and the deformable part has a fitting surface on the end away from the tolerance groove for conforming to the side of the arc-shaped splice after the deformable part deforms.

[0016] According to the above technical solution, the design of the arc-shaped concave part makes the deformation part fit the patient's skin tissue better, avoiding damage to the patient's skin tissue due to the deformation of the deformation part. At the same time, the fitting surface can abut against the side of the adjacent arc-shaped splicing piece after the deformation part is deformed, thereby ensuring that the fixing device after the inner diameter is finely adjusted is more stable and will not cause the deformation part to easily return to the initial state.

[0017] Preferably, the outer side of the arc-shaped splice is provided with a binding part and a snap-fit ​​groove for defining the position of the strap.

[0018] According to the above technical solution, the design of the binding part and the locking groove allows the strap to be fixed on the outside of the arc-shaped splice. In this way, the entire fixation device can be fixed on the outside of the patient's fracture site through the strap, thereby achieving the tightening of the fracture site. The binding part and the locking groove are designed for binding the strap, so as to select different binding methods in different scenarios.

[0019] Preferably, the binding part and the snap-fit ​​groove are arranged alternately.

[0020] According to the above technical solution, the purpose of the staggered arrangement is to ensure that the fixation device can be stably fixed to the patient's fracture site in different scenarios, even through a single binding part or snap-fit ​​groove.

[0021] Preferably, the arc-shaped splicing component is radially provided with a plurality of first deformation grooves and second deformation grooves, the first deformation grooves and second deformation grooves are staggered, and the length L1 of the first deformation grooves and the second deformation grooves is less than the width L2 of the arc-shaped splicing component.

[0022] According to the above technical solution, the entire fixation device has a certain deformation capacity in the radial direction, which makes it applicable to different fracture sites of patients, improves the applicability of the device, and at the same time ensures that the fixation device can be firmly bound to the fracture site of the patient, and tightens the fracture site of the patient in all directions.

[0023] Preferably, the arc-shaped splicing component is made of rubber and has memory metal wires embedded inside.

[0024] According to the above technical solution, the entire arc-shaped splice has a certain deformation and recovery capability, which facilitates the repeated use of the arc-shaped splice and improves the utilization rate.

[0025] Compared with the prior art, the beneficial effects of the present invention are: 1. By splicing together several arc-shaped connectors to form a fixation tube, the fracture sites of the patient's limbs can be quickly fixed, which can effectively improve the fixation efficiency of the fracture sites. At the same time, by splicing different numbers of arc-shaped connectors, it can be adapted to patients of different body types, which can effectively improve the applicability of the fixation device.

[0026] 2. By sliding the connector inside the adjustment groove, the inner diameter of the fixation device can be adjusted after the fixation device is assembled, so as to achieve fine adjustment to adapt to the patient's limbs. In addition, during the fine adjustment process, the tightness of the fixation on the patient's fracture site can be further improved, and the displacement of the fracture site can be avoided to prevent secondary injury.

[0027] 3. The design of the deformable part provides space for the connector to slide inside the adjustment groove, enabling fine-tuning of the inner diameter of the fixation device. To ensure that the deformable part conforms as closely as possible to the patient's skin tissue after deformation, a tolerance groove is designed to provide tolerance space for the deformation of the deformable part. The design of the arc-shaped concave part makes the deformation of the deformable part conform more closely to the patient's skin tissue, avoiding damage to the patient's skin tissue due to the deformation of the deformable part. At the same time, the contact surface can abut against the side of the adjacent arc-shaped splice after the deformable part is deformed, thereby ensuring that the fixation device is more stable after the inner diameter is fine-tuned, and preventing the deformable part from easily returning to its initial state.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example: Figure 1 and Figure 2 As shown, this embodiment discloses an emergency surgical fracture fixation device, including several arc-shaped splicing components 100. The arc-shaped splicing components 100 are made of rubber and have memory metal wires embedded inside, giving the entire arc-shaped splicing component 100 a certain degree of deformation and recovery ability, facilitating repeated use of the arc-shaped splicing component 100 and improving utilization rate. In this embodiment, there are 16 arc-shaped splicing components 100, each with an arc of 20° and a 2.5° adjustment and tolerance space. One side of the arc-shaped splicing component 100 is set as an insertion part, and the other side is set as an adjustment part. The insertion part of one arc-shaped splicing component 100 is inserted into the adjustment part of another arc-shaped splicing component 100 to complete the connection of any two arc-shaped splicing components 100, and the insertion part can slide inside the adjustment part. Several arc-shaped splicing components 100 are connected to form a fixation cylinder for fixing the fracture site, and the fixation cylinder is fastened with straps on the outside.

[0032] Specifically, the plug-in part includes a plug-in plate 201 and a plug connector 202. One end of the plug-in plate 201 is connected to the arc-shaped splicing piece 100, and the other end is provided with a plug connector 202. The cross-section of the plug connector 202 is triangular. The adjustment part includes an adjustment groove 301, which also has a triangular cross-section. However, the depth of the adjustment groove 301 is greater than the length of the plug connector 202, and the width of the end of the plug connector 202 is equal to the width of the end of the adjustment groove 301. This allows the plug connector 202 to have a certain sliding space inside the adjustment groove 301. The plug connector 202 is inserted into the adjustment groove 301 and is adapted to the adjustment groove 301. Through the mutual connection of the plug connector 202 and the adjustment groove 301, the fastening of the fixing device can be realized. Furthermore, the arbitrary assembly performance of the entire fixing device is stronger, and the adaptability of the fixing device is improved.

[0033] It should be noted that in actual use, the connectors 202 and adjustment grooves 301 of several arc-shaped splicing parts 100 need to be connected to each other to form a fixation device with a circular cross-section. Then, the entire fixation device is fitted onto the fracture site of the patient's limbs. In order to adapt to patients with different body shapes, the number and size of the arc-shaped splicing parts 100 can be selected according to the actual situation.

[0034] It needs to be further explained that, such as Figure 3As shown, when the connector 202 slides inside the adjusting groove 301, the adjusting groove 301 is deformed and widened by the squeezing force of the connector 202, thereby realizing the adjustment of the inner diameter of the entire fixing device.

[0035] To achieve a secure fastening of the fixing device after the inner diameter is adjusted, specifically, as follows: Figure 4 As shown, several limiting grooves 302 are symmetrically provided on the inner wall of the adjustment groove 301 for fixing the position of the connector 202. When the connector 202 slides deeper into the adjustment groove 301, the end of the connector 202 near the connector plate 201 will be stuck in the limiting groove 302 and cannot be reset. At this time, the state of the fixing device after the inner diameter is finely adjusted can be maintained to avoid the inability to clamp the fracture site of the patient due to loosening.

[0036] Furthermore, a deformation part 400 is provided on the inner side of the arc-shaped splice 100, located on one side of the adjustment groove 301. A tolerance groove 401 is provided at the connection between the deformation part 400 and the arc-shaped splice 100 to provide deformation space for the deformation part 400. The cross-section of the tolerance groove 401 is triangular, and the base of the triangle is located on the inner side of the arc-shaped splice 100. The design of the deformation part 400 provides space for the sliding of the connector 202 inside the adjustment groove 301, so that the inner diameter of the fixing device can be finely adjusted. In order to ensure that the deformation part 400 fits the patient's skin tissue as closely as possible after deformation, the tolerance groove 401 is designed to provide tolerance space for the deformation of the deformation part 400 and avoid the deformation part 400 from compressing the patient's skin tissue after deformation.

[0037] It should be noted that the deformable part 400 is provided with an arc-shaped concave part 402 for conforming to the patient's skin on the side away from the adjustment groove 301, so that after the deformable part 400 deforms, it can conform to the patient's skin tissue as much as possible. The deformable part 400 is provided with a contact surface 403 for conforming to the side of the arc-shaped splice 100 after the deformable part 400 deforms. The contact surface 403 can abut against the side of the adjacent arc-shaped splice 100 after the deformable part 400 deforms, thereby ensuring that the fixing device after the inner diameter is finely adjusted is more stable and will not cause the deformable part 400 to easily return to the initial state. This ensures the stability of the entire fixing device after tightening and avoids secondary injury to the patient due to the loosening of the fixing device. In this embodiment, the correction groove 401 is designed at the connection between the arc-shaped concave part 402 and the arc-shaped splice 100.

[0038] In this embodiment, as Figure 5As shown, the outer side of the arc-shaped splice 100 is provided with a binding part 500 and a locking groove 600 for defining the position of the bandage. The binding part 500 and the locking groove 600 are staggered. A through slot is formed between the binding part 500 and the arc-shaped splice 100 for the bandage to pass through. Through the design of the binding part 500 and the locking groove 600, the bandage can be fixed to the outer side of the arc-shaped splice 100. In this way, the entire fixation device can be fixed to the outer side of the patient's fracture site with the bandage, thereby achieving a tight fixation of the fracture site. The binding part 500 and the locking groove 600 are designed for binding the bandage, with the purpose of being able to fix different Different binding methods can be selected depending on the scenario. For example, when the patient's fracture site is the forearm, the fixation device can be simply fastened to the outside of the patient's forearm by passing the strap through the binding part 500 to fix the fracture site. However, when the patient's fracture site is the thigh, because the leg muscles are more developed, simply passing the strap through the binding part 500 cannot effectively fix the fracture site of the patient's thigh. In this case, if the strap is inserted into the locking groove 600 for secondary fixation and tightening, it can ensure that the fixation device is stably fixed to the fracture site of the patient's thigh and can play a good role in fixing the fracture site.

[0039] Furthermore, such as Figure 6 As shown, the arc-shaped splice 100 is radially provided with a plurality of first deformation grooves 700 and second deformation grooves 800. The radially arranged first deformation grooves 700 and second deformation grooves 800 are arranged alternately so that the arc-shaped splice 100 can deform in the radial direction. The length L1 of the first deformation grooves 700 and the second deformation grooves 800 is less than the width L2 of the arc-shaped splice 100. This is because when fixing the fracture site of a patient, the patient's limbs are not regular circles with a constant diameter. In order to make the fixation device fit the patient's skin better and play a better role in fixing the fracture site, the alternating arrangement of the first deformation grooves 700 and the second deformation grooves 800 can better fix the fracture site of the patient.

[0040] It should be further explained that, in actual use, the process of this invention is as follows: First, different numbers of arc-shaped splicing pieces 100 are assembled to form fixation devices of different diameters. When a patient has a limb fracture requiring emergency fixation, a fixation device of a suitable diameter can be selected and fitted onto the fracture site. Then, a bandage is passed through the bandaging part 500 or inserted into the snap-fit ​​groove 600. By tightening the bandage, the connector 202 is driven to slide inside the adjusting groove 301. During the sliding process of the connector 202 inside the adjusting groove 301, it is gradually restricted by the limiting groove 302, thus driving the connector 202 to slide. 2. If it cannot be retracted, the deformable part 400 will also deform due to the continuous sliding of the connector 202 inside the adjustment groove 301, compressing the fault tolerance groove 401, so that the arc-shaped concave part 402 fits the patient's skin. Moreover, during the deformation of the deformable part 400, the sides of the two adjacent arc-shaped splicing parts 100 will also come close to each other. At this time, the sides of the adjacent arc-shaped splicing parts 100 will abut against the contact surface 403, which can also further tighten the fixing device after the inner diameter is finely adjusted, and prevent the entire fixing device from becoming loose.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
