Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a portable surgical microscope. Background Technology

[0002] Surgical microscopes are high-precision medical devices widely used in neurosurgery, ophthalmology, otolaryngology, dentistry, and plastic surgery. They are primarily used to magnify the surgical field and enhance the precision of the surgeon's operations. However, traditional surgical microscopes are bulky and heavy, and are usually fixed in hospital operating rooms, making them inconvenient to carry around and difficult to use outdoors or in resource-constrained medical environments.

[0003] In recent years, with the diversification of medical needs, portable surgical microscopes have gradually become a new development direction, especially in scenarios such as battlefield rescue, field medicine, medical assistance in remote areas, and mobile medical vehicles, where they have broad application prospects. To reduce the weight of surgical microscopes, existing portable surgical microscopes have simplified the automatic adjustment structure and adopted manual adjustment of the microscope's field of view. However, the simplification generally results in a small adjustment range of the microscope's field of view. In addition, since the optical parts of the microscope are usually quite heavy, manual adjustment is difficult, increasing the burden on medical staff and affecting surgical efficiency.

Detailed Implementation

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

[0020] Example 1

[0021] like Figure 1-4As shown, a portable surgical microscope includes a support column 1, a clamping base 2, a lower horizontal arm 3, and an upper horizontal arm 4. The clamping base 2 is fixed to the lower end of the support column 1, and the lower horizontal arm 3 is provided at the upper end. The clamping base 2 is provided with a clamping groove. During installation, the clamping groove clamps the outside of the part to be installed, and then it is locked by a locking screw provided on the clamping base 2. The installation is convenient and quick, and it is suitable for various operating environments such as desktops and ambulance operating tables, ensuring surgical stability. One end of the lower horizontal arm 3 is sleeved on the upper end of the support column 1 and is rotatably connected to the support column 1. The upper horizontal arm 4 is arranged parallel above the lower horizontal arm 3, and one end of it is rotatably connected to the end of the lower horizontal arm 3 away from the support column 1. The other end is provided with a microscope assembly 5.

[0022] like Figure 1 , 2 As shown, the upper horizontal arm 4 contains a gas spring (not shown) to balance the weight of the microscope assembly 5. An adjusting screw 8 for adjusting the tension of the gas spring is also located at the top of one end of the upper horizontal arm 4. The gas spring provides a continuous reaction force to counteract the downward pull of the microscope assembly 5's own weight. When the head of the microscope assembly 5 drops, the tension of the gas spring is increased by adjusting screw 8; conversely, the tension is decreased until the head of the microscope assembly is balanced. This invention's gas spring uses the reaction force generated by the internal high-pressure gas to counteract the weight of the microscope assembly, achieving arm balance. This allows the operator to easily move the microscope to the desired position and maintain stability after release without continuously applying external force, ensuring the device can move flexibly and be stably positioned during surgery, making adjustments more convenient and faster.

[0023] In addition, such as Figure 1 , 2 As shown, the lower cross arm 3 is provided with a locking knob 6 at one end and a locking knob 7 at the other end. The locking knob 6 is used to adjust the rotational damping of the lower cross arm 3, and when the locking knob 6 is locked, the lower cross arm 3 is fixedly connected to the upper end of the support column 1. The locking knob 7 is used to adjust the rotational damping of the upper cross arm 4, and when the locking knob 7 is locked, the upper cross arm 4 is fixedly connected to the lower cross arm 3.

[0024] In the above structure, a rod is provided at the lower end of one end of the upper cross arm 4. The rod is inserted into a hole at one end of the lower cross arm 3. The upper cross arm 4 can rotate around the rod. The rod and the end of the upper cross arm form a step, restricting the displacement of the upper cross arm 4 in the axial direction of the hole. The lower cross arm 3 can rotate around the support column 1. Figure 4 As shown, through the above settings, the position adjustment range of microscope component 5 is large, that is, the field of view adjustment range of microscope component is large, the flexibility is good, and the application range is wide.

[0025] Example 2

[0026] Based on the structure of Example 1, such as Figure 1 , 2 As shown, the microscope assembly 5 is connected to the upper horizontal arm 4 via a hanging wall 9. One end of the upper horizontal arm 4 is provided with a tube 10. The upper end of the hanging wall 9 is inserted into the tube 10 and rotatably connected to the tube 10. It is also fixedly connected to the tube 10 via a locking nut 11 located at the top of the tube 10. The lower end of the hanging wall 9 is connected to the microscope assembly 5.

[0027] In the above structure, the front side of the insert 10 is provided with an adjustment knob 12, and the side wall of the insert 10 is provided with an adjustment knob 13. The adjustment knob 12 is used to adjust the brightness of the light, and the adjustment knob 13 is used to adjust the rotation damping of the wall hanging 9.

[0028] like Figure 1 , 2 As shown, the microscope assembly 5 includes a microscope body 51, a microscope base 52, and a connecting seat 53. The microscope body 51 is fixed on the microscope base 52, and the microscope base 52 is slidably connected to the connecting seat 53 via a slide rail assembly 54. The connecting seat 53 is connected to the wall mount 9. Furthermore, the microscope base 52 has a handle on its front side for easy handling, and each side has a magnification adjustment knob for adjusting the microscope magnification. It is also equipped with a high-brightness LED or laser light source to provide stable coaxial illumination.

[0029] like Figure 3 As shown, the portable surgical microscope also includes a foot switch 14, which is electrically connected to the slide rail assembly 54 and is used to drive the microscope mount 52 to move up and down along the vertical direction of the connecting seat 53, thereby controlling the distance from the microscope head to the operating table below, adjusting the focus, and making the field of view clearer.

[0030] In addition, the bottom of the lower crossarm 3 is also equipped with a foot pedal socket, a DC socket, and a power switch.

[0031] This portable surgical microscope weighs only 25 kg and can be easily packed into a 28-inch suitcase, and is also suitable for air transport. Doctors and medical teams can take it to mobile medical vehicles, temporary medical tents, and other environments. Simply open the suitcase, attach it to a table or lifting platform, and it can be quickly deployed in the operating room. This allows for flexible responses to various mobile medical needs, providing timely and efficient ophthalmological, dental, ENT, and surgical support to patients in resource-limited areas.

[0032] This utility model of portable surgical microscope is highly portable, can be carried around and deployed flexibly, and is suitable for various complex or resource-constrained medical environments, providing feasibility for global emergency medical rescue and medical care in remote areas;

[0033] Small in size and light in weight, it adopts a detachable support structure, which is easy to store and carry. It can be quickly fixed and the optics, lighting and support structure can be quickly adjusted according to the needs of surgery.

[0034] Lower procurement, transportation, and maintenance costs make it particularly suitable for resource-constrained medical institutions or emergency medical needs.
