[0036] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; "connection" can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] See also Figure 1 and Figure 2 The utility model provides a micromanipulation wrist support, which specifically includes a base 10, a support rod 20, a wrist support pad 30 and an adjuster 40. The base 10 can be installed close to a surgical mattress 50; the support rod 20 is tilted relative to the base 10 and the bottom end of the support rod 20 is hinged to the base 10. The wrist support pad 30 is arranged on the top of the support rod 20 and suspended above the surgical mattress 50 to avoid contact with the patient on the surgical mattress 50. The first end of the adjuster 40 is connected to the base 10 and the second end of the adjuster 40 is connected to the position near the bottom end of the support rod 20. The base 10, the support rod 20 and the adjuster 40 together form a triangular support structure, which has a very stable support effect and can prevent the wrist support pad 30 from shaking and affecting the doctor's operation. The adjuster 40 can adjust the tilt angle of the support rod 20 so that the wrist support pad 30 can be at different heights and different angles to meet the needs of surgery. When the doctor is operating a microscopic instrument, the wrist can be placed on the wrist rest 30 to avoid fatigue caused by long-term suspension. The doctor can focus on treating the patient, improve the efficiency of the operation, and increase the stability and accuracy of the operation.

[0038] In a preferred embodiment, see again Figure 1 and Figure 2The wrist support pad 30 is a groove structure with an opening facing upward and is divided into a straight section 31 and an arc section 32 along the extension direction of the wrist support pad 30. The straight section 31 is fixedly mounted on the top of the support rod 20, so that the arc section 32 is basically in a horizontal state, which can effectively support the doctor's wrist. The arc-shaped groove structure is compatible with the wrist and is close to the curvature of the wrist when it is relaxed, which can improve the comfort of the wrist when it is supported. Moreover, the wrist support pad 30 can be preferably an elastic pad, such as a silicone pad or a rubber pad, etc., to further improve the user experience.

[0039] Wherein, in one embodiment, Figure 1 and Figure 2 As shown, the adjuster 40 includes a sleeve 43, a forward-rotating screw 41 hinged on the base 10, and a reverse-rotating screw 42 hinged on the support rod 20. The first end of the sleeve 43 is provided with a forward-rotating thread adapted to the forward-rotating screw 41, and the second end of the sleeve 43 is provided with a reverse-rotating thread adapted to the reverse-rotating screw 42. The first end of the sleeve 43 is sleeved outside the forward-rotating screw 41, and the second end of the sleeve 43 is sleeved outside the reverse-rotating screw 42. During operation, by rotating the sleeve 43 in a certain direction, the forward-rotating screw 41 and the reverse-rotating screw 42 can be moved closer to or away from each other, so that the overall length of the adjuster 40 can be finely adjusted, and then the inclination angle of the support rod 20 can be accurately adjusted. Moreover, since the threaded connection also has a static self-locking performance, when adjusted in place, the adjuster 40 can provide reliable support for the support rod 20 to prevent the inclination angle of the support rod 20 from changing. Among them, a first mounting block 12 is provided on the base 10, and one end of the forward-rotating screw 41 is hinged to the first mounting block 12; a second mounting block 23 is provided on the support rod 20, and one end of the reverse-rotating screw 42 is hinged to the second mounting block 23, so as to facilitate the installation of the regulator 40.

[0040] In another embodiment, Figure 3 As shown, the regulator 40 can also be a first electric push rod 44, the first end of which is hinged on the base 10 and the second end of which is hinged on the support rod 20. The doctor can adjust the length of the first electric push rod 44 as needed, so as to achieve the purpose of adjusting the inclination angle of the support rod 20. Among them, the length adjustment method of the electric push rod is a prior art and will not be repeated here. Moreover, the electric push rod can remain in a self-locking state after the length is adjusted in place due to the existence of a self-locking force (also known as static load capacity), thereby ensuring that the regulator 40 can reliably support the support rod 20.

[0041] In a more preferred embodiment, the support rod 20 may be a second electric push rod, and the doctor may adjust the length of the second electric push rod according to the needs, and cooperate with the angle adjustment of the adjuster 40 to make the reachable area of ​​the wrist support pad 30 larger, which is more in line with the surgical needs. Figure 2The second electric push rod may include a square outer tube 21 and a square inner rod 22, and also have a built-in micro motor, transmission assembly and controller, etc. The square inner rod 22 can be driven by the micro motor to reciprocate in the square outer tube 21; the bottom end of the square outer tube 21 is hinged on the base 10, and the top end of the square inner rod 22 is provided with a wrist support pad 30. Among them, the square outer tube 21 and the square inner rod 22 are nested with each other and can also achieve circumferential limiting to prevent the wrist support pad 30 from circumferential deflection. In addition, the second mounting block 23 is preferably arranged in the middle of the square outer tube 21 to ensure the stability of the support. Furthermore, the maximum length of the support rod 20 in the extended state can be more than three times the length of the base 10 to better meet the operation requirements of the operation.

[0042] In addition, see again Figures 1 to 3 The base 10 may be provided with a plurality of fixing screws 11 arranged at intervals, and the base 10 may be installed on the auxiliary device next to the surgical mattress 50 through the plurality of fixing screws 11 to ensure the stability of the overall structural installation, thereby ensuring the reliability of the wrist support during the surgical process.
