Description

Technical Field

[0001] This utility model relates to a fixation device for bilateral radial artery interventional treatment, belonging to the field of medical device technology. Background Technology

[0002] The standard puncture route for coronary intervention is the right radial artery. However, due to anatomical variations or puncture failure, it may also be the left radial artery or right brachial artery. To stabilize the puncture route, a hand support or plate is generally needed. Currently, there are two practical problems that urgently need to be addressed in clinical practice: First, when using a right radial artery fixation hand support, homemade devices are often chosen, but these are cumbersome to operate and may even lead to displacement during the procedure. Second, if the left radial artery puncture route is used, there is currently no fixation device available. Patients often need to fix their left arm and hand in front of their body themselves, which is physically demanding for extended periods, leading to instability at the puncture site. Moreover, it affects the operator's operation and makes prolonged operation difficult, especially in obese patients.

[0003] Therefore, there is an urgent need in this field for an upper limb fixation brace or support device for interventional procedures to stabilize the puncture point and reduce the interventional workload for patients and doctors. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Reference Figure 1 and Figure 2 A fixation device for bilateral radial artery interventional treatment includes a fixation clamp assembly 1 for connecting to an operating table. The fixation clamp assembly 1 has a fixation plate clamp 11 with a clamping groove 111. A height adjustment rod 3 is hinged to one side wall of the fixation plate clamp 11 via a hinge assembly 2. At least one positioning bolt 12 is screwed onto the side of the fixation plate clamp 11 away from the height adjustment rod 3, and the positioning bolt 12 passes into the clamping groove 111. A lateral adjustment rod 4 is slidably provided inside the height adjustment rod 3 along the direction close to or away from the fixation plate clamp 11. One end of the height adjustment rod 3 is bent at 90° to form a lateral adjustment part 41. The end of the lateral adjustment part 41 away from the height adjustment rod 3 is provided with a connecting rod 42 that slides along the direction close to or away from the height adjustment rod 3. The connecting rod 42 and the lateral adjustment part 41 are limited and fixed by a locking bolt 10 screwed to the outer wall of the end of the lateral adjustment part 41 away from the height adjustment rod 3. The end of the connecting rod 42 away from the lateral adjustment part 41 is detachably connected to a hand support plate 5. In this embodiment, in order to ensure the connection stability as much as possible, two positioning bolts 12 are preferably arranged symmetrically.

[0021] In use, the height adjustment rod 3 with hinged setting can meet more height adjustment possibilities of the horizontal adjustment rod 4; the clamping groove 111 in the fixed plate clamp 11 and the clamping cooperation with the positioning bolt 12 can clamp and lock most of the rods, whether they are cylindrical rods, square rods or other shapes, when clamped and connected with the operating table, while the connection stability is strong.

[0022] Reference Figure 1 and Figure 2 In a further embodiment, the hinge assembly 2 includes a hinge seat 21, a support rod 22, a hinge seat 23, a limiting bolt 24, and a locking nut 25.

[0023] One end of the height adjustment rod 3 is hinged to the first hinge seat 21 through the limit bolt 24 and fixed and rotated by the locking nut 25. Two support rods 22 are installed and are distributed at an angle on two opposite sides of the height adjustment rod 3. One end of the support rod 22 is hinged to the outer wall of the height adjustment rod 3 through the hinge shaft. The second hinge seat 23 is fixedly installed on the side wall of the fixed plate clamp 11 and has two corresponding to the support rod. The other end of the support rod 22 is hinged to the second hinge seat 23 through the hinge shaft. When the height adjustment rod 3 is adjusted to a suitable angle, the limit bolt 24 and the height adjustment rod 3 can be tightened and fixed by the locking nut. The inclined support force of the support rod 22 can further ensure the stability of the height adjustment rod 3 when it is fixed and supported.

[0024] In a further embodiment, the outer wall of the fixing plate clamp 11 is provided with a storage groove 112 for embedding the height adjustment rod 3 and the lateral adjustment rod 4. The lateral adjustment rod 4 is connected to the inner wall of the storage groove 112 by a transition fit. The first hinge seat 21 and the second hinge seat 23 are both provided on the inner wall of the storage groove 112. When the fixing device is not needed, the height adjustment rod 3 and the lateral adjustment rod 4 can be rotated to the horizontal and stored and fixed through the storage groove 112, making it convenient to take out.

[0025] Reference Figure 2 and Figure 3 In a further embodiment, the second hinge seat 23 is slidably disposed on the inner wall of the storage groove 112. The bottom end of the second hinge seat 23 is inverted "T" shaped. A sliding groove 1121 is provided on the bottom wall of the storage groove 112 to cooperate with the sliding of the hinge seat. The interaction between the second hinge seat 23 and the sliding groove 1121 can improve the adaptability of the height adjustment rod 3 when it is rotated and stored.

[0026] Reference Figure 1 and Figure 2 The hand support plate 5 has a support plate body 51, which is a four-sided panel structure composed of a support base plate 511 and three limiting plates 512 arranged perpendicular to the support base plate 511. Two of the limiting plates 512 are arranged in parallel intervals, and another limiting plate 512 is perpendicular to the two parallel limiting plates 512 and located on one side of the two limiting plates 512. The support plate body 51 can be made of any material. In this embodiment, the support plate body 51 is preferably an integrally formed plastic panel structure. A sponge layer 6 can be detachably installed on the inner wall of both the support base plate 511 and the limiting plates 512. A sleeve 52 that is inserted into the connecting rod 42 is integrally formed on the outer wall of any of the parallel limiting plates 512. A locking bolt 7 is screwed onto the sleeve 52 to fix the connecting rod 42 inside the sleeve 52. This arrangement also enables the support plate body 51 to be rotated and adjusted, further improving the adaptability of the fixing device.

[0027] Furthermore, the sponge layer 6 is detachably connected to the support base plate 511 and the limiting plate 512 via the Velcro assembly 8. Specifically, the Velcro assembly 8 has a Velcro mother tape installed on the inner wall of the support base plate 511 and the limiting plate 512, and a Velcro daughter tape installed on the sponge layer 6. This is existing technology and will not be described in detail.

[0028] Furthermore, the support base plate 511 has a length ranging from 30-40cm and a width ranging from 5-10cm; two parallel limiting plates 512 have the same length as the support base plate 511, another limiting plate 512 has the same length as the support base plate 511, and all three limiting plates 512 have the same height, ranging from 5-10cm, which can meet the support needs of most people. Larger support base plates 511 can also be manufactured according to the patient's height and weight requirements.

[0029] Reference Figure 1 and Figure 2 The height adjustment rod 3 and the lateral adjustment rod 4 are fixed by a fixing bolt 9 screwed onto the outer wall of the end of the height adjustment rod 3 away from the fixing plate clamp 11. This arrangement allows for sliding adjustment of the lateral adjustment rod 4 and the height adjustment rod 3, as well as rotation adjustment, to accommodate more support requirements and further improve the adaptability of the fixing device.
