Description

Technical Field

[0001] The utility model relates to the field of medical equipment, and in particular to a medical hand support. Background Art

[0002] When deep or critical neurosurgery is required, it is often performed with the assistance of a microscope. This type of surgery is called microsurgery. Microsurgery requires extremely high arm stability and precise manipulation.

[0003] In current microsurgery, one solution is to rely on the strength of the doctor's arm to operate in mid-air. If the operation lasts too long, the doctor's arm will inevitably be overtired. More importantly, such mid-air operation affects the stability and accuracy of the operation. Another solution is to have an arm support. The arm support in the existing technology is divided into two support methods: support on both sides of the forearm and support on the elbow joint. However, during the microsurgery process, the doctor usually needs to change the operation path. In one operation, the operation path often needs to be changed several times according to the actual situation. This requires timely adjustment of the height of the arm support to meet the doctor's different support requirements from sitting to standing.

[0004] Currently, adjusting the height of the hand support requires the assistance of an operating room nurse or other doctor near the sterile area of ​​the operating table, or the surgeon performing the microsurgery manually adjusting the lower support rod. This presents several problems: Firstly, it may contaminate the sterile area; secondly, a single adjustment may not meet the surgeon's microsurgery requirements. Furthermore, the surgeon performing the microsurgery must repeatedly adjust the hand support manually, significantly reducing surgical efficiency and causing significant complications during the operation.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0028] Example

[0029] Please refer to Figure 1-Figure 3 , shown is a schematic structural diagram of a medical hand support frame in an embodiment of the present utility model;

[0030] This embodiment provides a medical hand support, comprising:

[0031] A base 1, with a fixing member 11 provided on the top of the base 1;

[0032] The lifting mechanism includes a lifting cylinder 3, a foot switch 4, an inner sleeve 5, an outer sleeve 6, and a limiter. The foot switch 4 is provided on one side of the fixing member 11 and is hinged to the fixing member 11; the piston rod of the lifting cylinder 3 is connected to the foot switch 4; the inner sleeve 5 is fixedly sleeved on the outside of the cylinder of the lifting cylinder 3; the outer sleeve 6 is sleeved on the outside of the inner sleeve 5, and the bottom end of the outer sleeve 6 is connected to the base 1; the outer wall of the inner sleeve 5 is slidably connected to the inner wall of the outer sleeve 6 through the limiter;

[0033] The hand supporting plate 2 is connected to the top of the inner sleeve 5.

[0034] Next, the medical arm support according to this exemplary embodiment will be further described.

[0035] In some embodiments of the present application, a fixing member 11 is provided at the top of the base 1. A through hole is provided on one side of the fixing member 11 for the foot switch 4 to pass through and move up and down. One end of the foot switch 4 is inserted into the through hole and hingedly connected to the fixing member 11 at the through hole. A through hole is provided at the top of the fixing member 11 for the piston rod of the lifting cylinder 3 to pass through, so that the piston rod can be connected to the foot switch 4 and the lifting of the lifting cylinder 3 is controlled by the foot switch 4. The inner sleeve 5 is fixedly mounted on the outside of the cylinder barrel of the lifting cylinder 3 so that the inner sleeve 5 rises and falls synchronously with the lifting of the lifting cylinder 3. The hand support plate 2 is connected to the top of the inner sleeve 5, thereby driving the hand support plate 2 to adjust its height. The outer sleeve 6 is mounted on the outside of the inner sleeve 5, and the bottom end of the outer sleeve 6 is connected to the base 1, that is, the outer sleeve 6 always remains fixed and motionless. The outer wall of the inner sleeve 5 is slidably connected to the inner wall of the outer sleeve 6 via a limit member. The sliding connection between the outer sleeve 6 and the inner sleeve 5 can, on the one hand, serve as a limit guide for the inner sleeve 5 and the lifting cylinder 3 , and on the other hand, can improve the overall strength of the lifting mechanism and improve the aesthetics.

[0036] The above-mentioned foot pedal switch is used to exchange the high-pressure gas in the cylinder. Under the action of pressure, the piston rod in the lifting cylinder 3 can move up and down. By cooperating with the foot pedal switch, the lifting function of the hand support plate 2 can be realized. Specifically, the foot pedal switch can be set to move the hand support plate 2 upward or downward.

[0037] As a preferred embodiment, the inner sleeve 5 and outer sleeve 6 are both cylindrical, and the position-limiting members include steel balls that are rolled and embedded in the inner wall of the outer sleeve 6. A chute 71 adapted for the steel balls is provided on the outer wall of the inner sleeve 5. By configuring the inner sleeve 5 and outer sleeve 6 as cylindrical, they are used to support the lifting cylinder 3 and increase strength. Furthermore, to prevent relative rotation between the cylindrical inner sleeve 5 and outer sleeve 6, steel balls are disposed within them. During lifting, the steel balls roll within the chute 71, limiting and guiding the inner sleeve 5 and outer sleeve 6, thereby improving stability during lifting.

[0038] As a preferred embodiment, the inner sleeve 5 and the outer sleeve 6 are both in the shape of a square tube, and the limiting member includes a slide rail 72 and a slider 73. The slide rail 72 is fixed to the inner wall of the outer sleeve 6, and the slider 73 is fixed to the outer wall of the inner sleeve 5. The slider 73 is slidably connected to the slide rail 72. In order to further increase the stability of the hand support and prevent shaking during lifting, the inner sleeve 5 and the outer sleeve 6 are configured as square tubes and slide by means of the slide rail 72 and the slider 73. Since the support and guide area of ​​the slide rail 72 and the slider 73 is larger than the guide area of ​​the steel ball, the stability during lifting can be further improved.

[0039] As a preferred embodiment, the above-mentioned hand support board 2 is used to provide support for the doctor's hands. The hand support board 2 can specifically be a plate material, and the hand support board 2 can be a metal material, which can meet the strength requirements during use.

[0040] As a preferred embodiment, the top of the armrest 2 is provided with an elastic armrest pad 21 in an arc shape. The elastic armrest pad 21 is used to alleviate excessive arm muscle tension during support and improve arm comfort. Elasticity generally refers to a material that can return to its original shape after the external force is removed.

[0041] Specifically, the elastic hand rest pad 21 is made of sponge, silicone, or polyurethane elastomer. The sponge is made of wood cellulose fibers or foamed plastic polymers. The sponge is a soft gel with good resilience, softness, and breathability. The sponge elastic hand rest pad 21 is fixed to the hand rest plate 2. When the surgeon performs microsurgery, the surgeon's arm contacts the elastic hand rest pad 21. This, on the one hand, does not affect the surgeon's precision and accuracy during the surgical procedure, and on the other hand, significantly reduces arm fatigue and discomfort, ensuring the smooth progress of the surgery and thereby improving the efficiency of the procedure.

[0042] As a preferred embodiment, the armrest of the present application further includes a fixing sleeve 8, which is fixed to the base 1 and sleeved onto the outside of the bottom of the outer sleeve 6. A through hole is provided on one side of the fixing sleeve 8 for the foot switch 4 to pass through and move up and down. By providing the fixing sleeve 8, the outer sleeve 6 is fixed to the base 1, thereby supporting and fixing the outer sleeve 6, and the through hole provided on one side does not affect the up and down movement of the foot switch 4.

[0043] As a preferred embodiment, the above also includes a limiting sleeve 9, which is sleeved on the top of the outer sleeve 6 and has a through hole for the inner sleeve 5 to pass through. By arranging the limiting sleeve 9 on the top of the outer sleeve 6, it can limit the slider 73 on the side wall of the inner sleeve 5, and the through hole for the inner sleeve 5 to slide is opened, which does not affect the extension and contraction of the inner sleeve 5.

[0044] As a preferred embodiment, a lockable roller 12 is provided at the bottom of the base 1. The lockable roller 12 facilitates the movement of the arm support and facilitates the doctor to adjust the placement position during use.

[0045] As a preferred embodiment, the base 1 is made of stainless steel, angle steel, plastic, or wood. Stainless steel offers excellent weldability, corrosion resistance, and polishability. When determining the type of stainless steel to use, the desired aesthetic standards, the corrosiveness of the local atmosphere, and the cleaning regimen to be employed are primary considerations. Antibacterial stainless steel has a kill rate exceeding 99% against Escherichia coli and Staphylococcus aureus, and also exhibits significant killing effects against other bacteria such as Candida albicans and Trichoderma, demonstrating excellent broad-spectrum antibacterial properties and long-lasting antibacterial properties.

[0046] As a preferred embodiment, the shape of the base 1 can be circular, rectangular, triangular, Y-shaped, X-shaped, etc., and can be determined based on factors such as the specific size and weight of the hand support pad, and the forces that the hand support needs to withstand during microsurgery. Specifically, the base 1 can be configured as a rectangle to provide stable support while minimizing the space occupied in the operating room and facilitating the placement or movement of other equipment. An X-shaped base 1 refers to a base 1 composed of four support legs spliced ​​together to form an X shape.

[0047] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
