Description

Technical Field

[0001] This utility model belongs to the field of medical devices, and specifically relates to a surgical triangular fixation frame. Background Technology

[0002] In recent years, the incidence of limb traumatic injuries has been rising, threatening people's lives and health, and its adverse effects on society are becoming increasingly apparent. If limb traumatic injuries are not treated promptly, they can lead to pain and swelling in the limbs; in more severe cases, they can cause organic damage and functional impairment, and may even trigger complications such as massive bleeding and venous thrombosis.

[0003] Currently, in limb trauma surgery, the limbs need to be immobilized to facilitate the operation. During surgery, the patient's limbs generally need to be positioned in a specific posture. The existing conventional method is to directly support the patient's limbs with supportive materials such as cotton pads. This method seems simple, but it has poor stability and is prone to limb movement during the operation, causing harm to the patient and making it inconvenient for the doctor to operate. Some hospitals have also used special medical leg supports, but these are all relatively simple triangular support frames, which have poor stability.

[0004] Therefore, there is an urgent need for a surgical fixation stent that is stable and securely fixed. Summary of the Invention

[0005] To address the issues of poor stability and difficulty in ensuring secure fixation in existing external fixation devices, this invention provides a surgical triangular fixation frame. A support plate is installed inside the surgical triangular fixation frame to improve its stability. Through holes are provided on the surgical triangular fixation frame, support plate, and fixation bracket. During use, after placing the hemostatic and hemostatic collar, the tension rope is cut and tied to the through hole for further fixation, which enhances the stability of the fixation. Anti-slip grooves on the surface of the surgical triangular fixation frame provide anti-slip and anti-detachment effects.

[0006] This utility model provides a surgical triangular fixation frame, including a triangular prism-shaped fixation frame body. Each side plate of the fixation frame body is provided with a first through hole on both sides. An insertion hole is provided at the top center of the side plate. The interior of the fixation frame body is hollowed out, and a support plate perpendicular to the side plate of the fixation frame body is fixedly installed at the center of the hollowed-out interior. A second through hole is opened on the support plate. A slot is provided at the bottom of the fixation support, and the slot at the bottom is detachably installed in the insertion hole.

[0007] It also includes a hemostatic collar, on which two or four tension ropes are fixedly installed.

[0008] The internal support plate of the surgical triangular fixator supports the one-piece molded side plate, improving the stability of the surgical triangular fixator. Each of the three vertices of the support plate has a groove that matches the first slot of the lower limb fixation bracket and the second slot of the upper limb fixation bracket. When the fixation bracket can be inserted into the insertion hole, the support plate provides support for the fixation bracket, preventing it from shifting downwards. After the hemostatic ring is fixed to the limb, one of the loop-shaped tension ropes can be cut to the same length. The two cut pieces are then passed through the first and second through holes and tied to secure the upper part of the limb. Excess tension rope can be cut from the ring and reused as a binding rope, passed through the first and second through holes and tied to secure the front end of the limb. In existing technologies, the tension rope of the hemostatic ring becomes useless after reaching the surgical position. The inventor's reuse of this waste rope as a binding rope achieves better fixation and reduces surgical costs.

[0009] Preferably, the surgical triangular fixation frame has three insertion holes at the top center of the side plate, and the three insertion holes are respectively located at the three vertices of the surgical triangular fixation frame.

[0010] The three angles of the surgical triangular fixation frame are different to suit different usage situations. The fixation bracket can be selectively installed at the insertion hole according to the actual situation.

[0011] Preferably, the side plate of the surgical triangular fixation frame is provided with anti-slip grooves. These grooves contact the hemostatic rings or the patient's limbs to prevent slippage and provide auxiliary fixation.

[0012] Preferably, the fixation support includes one or both of an upper limb fixation support and a lower limb fixation support; the lower limb fixation support has a convex support surface and a first slot at the bottom; the upper limb fixation support has a concave support surface and a second slot at the bottom.

[0013] More preferably, the upper limb fixation support has third through holes on both sides of the support surface. After the hemostatic ring is installed, the excess tension rope is cut off from the ring and reused as a binding rope. It is then passed through the third through holes on both sides of the support surface and knotted to help fix the front end of the upper limb to the upper limb fixation support.

[0014] Preferably, the longitudinal section of the surgical triangular fixator is a right triangle, and each angle of the right triangle is rounded.

[0015] Preferably, the tension rope is a loop tension rope, and there are at least two of each of the first through hole, the second through hole, and the third through hole, which are respectively distributed on both sides of the side plate, the support plate, and the upper limb fixing support surface.

[0016] Preferably, the surgical triangular fixation frame is made of plastic or alloy material, has a certain thickness, can bear the weight of the limb, is resistant to high temperature, can be repeatedly cleaned and disinfected, and has the characteristics of lightweight structure, comfort and stability, and wide applicability.

[0017] The surgical triangular fixator provided by this utility model achieves the following beneficial effects:

[0018] 1) By setting a support plate inside the surgical triangular fixator to support its side plates, the stability of the fixator is improved, and at the same time, it can provide support for the fixation bracket to prevent it from shifting downward;

[0019] 2) Anti-slip grooves are provided on the side plate surface. When in use, the anti-slip grooves come into contact with the hemostatic ring and limb to prevent slipping and detachment, thus assisting in fixation.

[0020] 3) Through holes are provided on each plate of the triangular fixation frame, through which the tension rope can be passed and fixed, which improves the firmness of the fixation of the patient's limb;

[0021] 4) Insert holes are provided at the three corners of the triangular bracket. The different angles of the three corners can adapt to different usage situations and meet different needs.

[0022] 5) The upper limb fixation brace and lower limb fixation brace can help fix the limb and prevent it from slipping. Attached Figure Description

[0032] like Figure 1 The image shows a surgical triangular fixation frame, comprising a triangular prism-shaped fixation frame body 1, and a lower limb fixation support 3 and an upper limb fixation support 4 used in conjunction with it. Each side plate of the fixation frame body 1 is provided with a first through hole 1-3 on both sides, and an insertion hole 1-1 is provided on the three corners of the side plate. The interior of the fixation frame body 1 is hollowed out, and a support plate 1-4 perpendicular to the side plate of the fixation frame body is fixedly installed at the center of the hollowed-out interior. A second through hole 1-5 is opened on the support plate, and a groove is provided at each of the three vertices of the support plate 1-4.

[0033] Figure 3 The image shown is of the lower limb fixation brace 3. Figure 4 The image shows an upper limb fixation support 4. The lower limb fixation support 3 has a convex support surface and a first slot 3-1 at the bottom. The upper limb fixation support 4 has a concave support surface and a second slot 4-1 at the bottom. The grooves at the three vertices of the support plate 1-4 match the first slot 3-1 of the lower limb fixation support 3 and the second slot 4-1 of the upper limb fixation support 4. The slots at the bottom of the first slot 3-1 and the second slot 4-1 are detachably set in the insertion hole 1-1, which can be used for upper limb and lower limb fixation respectively according to the actual situation. The upper limb fixation support 4 is provided with a third through hole 4-2, which can be used with the help of the tension rope 2-1 that can be cut and reused to fix the front end of the upper limb and prevent it from slipping.

[0034] Furthermore, the side plate surface of the fixing frame body 1 is provided with anti-slip grooves 1-2, which can help fix the hemostatic and hemostatic collar 2.

[0035] The specific usage method is as follows:

[0036] Example 1: Using a surgical triangular fixation frame to immobilize the lower limb

[0037] like Figure 5 and Figure 6 As shown, first, the hemostatic loop 2 is slipped onto the patient's lower limb by pulling the tension rope 2-1. According to the angle required for the surgery, the patient's lower limb is raised to the required height. The fixation frame body 1 is placed at a suitable angle. The first slot 3-1 of the lower limb fixation support 3 is inserted into the insertion hole 1-1, so that it is located below the knee joint. One of the loop tension ropes 2-1 is cut to the same length and passed through the first through hole 1-3 on the side plate and the second through hole 1-5 on the support plate in sequence. The tension rope 2-1 is tied tightly. The anti-slip groove 1-2 on the side plate surface is used for auxiliary fixation to complete the fixation of the lower part of the lower limb. The excess tension rope 2-1 is cut off from the loop and reused as a binding rope. Similarly, it is passed through the first through hole 1-3 on the side plate and the second through hole 1-5 on the support plate in sequence and tied tightly to complete the fixation of the upper part of the lower limb.

[0038] Example 2: Using a surgical triangular fixation frame to immobilize the upper limb

[0039] like Figure 7 As shown, first, the hemostatic loop 2 is slipped onto the patient's upper limb by pulling the tension rope 2-1. The fixation frame body 1 is positioned at a suitable angle, and the first slot 4-1 of the upper limb fixation bracket 4 is inserted into the insertion hole 1-1. One of the loop tension ropes 2-1 is cut off and passed through the first through hole 1-3 on the side plate and the second through hole 1-5 on the support plate in sequence. The tension rope 2-1 is then tied tightly. The anti-slip groove 1-2 on the side plate surface assists in fixation, completing the fixation of the upper part of the upper limb. The excess tension rope 2-1 is cut off from the loop and reused as a binding rope. Similarly, it is passed through the first through hole 1-3 on the side plate and the second through hole 1-5 on the support plate in sequence, and the tension rope 2-1 is tied tightly, completing the fixation of the upper part of the upper limb. Furthermore, the tension rope 2-1 cut off from the loop can also be passed through the third through hole 4-2 of the upper limb fixation bracket 4 and tied tightly to assist in fixation and prevent the limb from slipping.

[0040] In addition, when the fixation frame is placed on the operating table, the anti-slip grooves 1-2 on the surface of the bottom side plate can also increase the friction with the operating table, which can effectively prevent the fixation frame from slipping on the operating table.

[0041] The surgical triangular fixation frame provided by this utility model improves the stability of the fixation frame by setting a support plate at the internal center. At the same time, anti-slip grooves are set on the surface of the side plates, and through holes are set on the side plates and support plates. The tension rope on the hemostatic collar can be passed through the through holes and tied, which plays an auxiliary role in fixing the limb. Insertion holes are provided at the top of the three side plates to be used with upper limb fixation supports and lower limb fixation supports, which can adapt to different usage situations and meet different needs.
