Problems solved by technology

At present, most operations still rely on surgical shadowless lamps, cold LED headlights with optical fiber, etc. Due to the narrow surgical field, the doctor's body, surgical instruments, human anatomical structure, etc., the brightness of the light that really enters the field of view is not enough, especially for deep In the process of surgery, due to the influence of the location and size of the lesion, the doctor is required to constantly change the direction and angle of the field of view, which requires constant adjustment of the position of the shadowless lamp. Unclear about the possibility of accidental injury, threatening surgical safety

Embodiment 1

[0046] Such as figure 1 The electrocoagulation tweezers shown include a tweezers body and a monitor. LEDs are arranged on the tweezers body. The tweezers body includes a tweezers body and a tweezers seat at one end of the tweezers body. Locator, the LED is installed on the locator, the battery is installed in the tweezers seat, the outer side of the tweezers body is equipped with a wire storage slot, the line connecting the battery and the LED is located in the wire storage slot, and the periphery of the wire storage slot is provided with a fixed line buckle ; There is a miniature video recording device (model SA-DH420, Shenzhen Shi'an Electronic Technology Co., Ltd.) on the tweezers seat, and the miniature video recording device is electrically connected with the battery; the monitor (TCL-ML20) is electrically connected with the miniature video recording device. The diameter of the camera head of the miniature video recording device is 2-4mm.

[0047] The distance between th...

Embodiment 2

[0053] Such as image 3 The tweezers shown are basically the same as in Example 1, the difference is:

[0054] The luminous intensity of the LED is 100mcd, the illuminance is 5000lux, the color temperature is 3000K, the diameter of the light spot is 100mm, the illumination depth is 450mm, and the space angle is 110 degrees; the diameter of the circular lamp is 5mm; the packaging method of the LED is metal base epoxy packaging.

[0055] The body of the tweezers is provided with a water pipe leading to the tips of the tweezers.

[0056] The tweezers body includes two nickel sheets oppositely arranged, and the locator includes two blades, and the two blades are relatively rotatably connected on both sides of one of the nickel sheets, and the other nickel sheet falls between the two blades and is connected to the gap between the two blades. The spacing is not greater than 1mm, and two oppositely arranged limit blocks are arranged on both sides of the other nickel sheet.

Embodiment 3

[0060] It is basically the same as Example 1, the difference is:

[0061] The luminous intensity of the LED is 200mcd, the illuminance is 9000lux, the color temperature is 5000K, the spot diameter is 200mm, the illumination depth is 300mm, the space angle is 150 degrees, and the luminous color is colored white light.

[0062] The LED is a circular lamp with a diameter of 2mm; the packaging method of the LED is ceramic base epoxy encapsulation.

[0063] The surface of the tweezers is covered with a gold layer with a thickness of 0.08 mm, and a drip system is implanted in the tweezers.

[0064] An insulating insert is arranged between one pole of the battery and the LED, and a battery is arranged between the LED and the battery. When the fluorescent agent used in the operation is BODIPY (fluorine boron dipyrrole), the wavelength of the LED is 490-495nm.

Abstract

The invention discloses fluorescent development tweezers. The fluorescent development tweezers comprise a tweezers body, and an LED and a battery electrically connected with the LED are arranged on the tweezers body. The tweezers body comprises a main tweezers body and a tweezers seat arranged at one end of the main tweezers body, and the other end of the main tweezers body is provided with a tweezers tip. A locator is arranged at the tweezers tip, the LED is installed on the locator, and the battery is installed in the tweezers seat. A wire storing groove is formed in the outer side of the main tweezers body, and a circuit connected with the battery and the LED is located in the wire storing groove. The periphery of the wire storing groove is provided with a line fixing buckle, micro type video equipment is arranged on the tweezers seat, and the micro type video equipment is electrically connected with the battery. According to the fluorescent development tweezers, different types of fluorescent agents can be aroused, and the defect that a fluorescent development technology is expensive in the prior art is effectively overcome. Meanwhile, the whole operation process can be recorded, images can also be led out to a monitor, the images are amplified, an operation physician can watch the monitor to operate, and therefore the operation can be more accurate.

Description

technical field [0001] The invention relates to a fluorescent developing tweezers. Background technique [0002] Surgical tweezers are used to replace the hands of physicians. They are made into various shapes according to the needs of different operations. They are essential tools for clamping diseased tissues, organs and dressings, and are also used for high-frequency and radio-frequency electrocoagulation to stop bleeding; Through the pipeline system installed in the tweezers, non-ionized water is introduced to wash the wound surface, prevent the formation of eschar and adhere to the tissue. During the whole operation process, it basically does not leave the hand. [0003] In recent years, modern surgical techniques have developed by leaps and bounds, and minimally invasive surgery is one of its characteristics. Surgeons must have keen eyes and precise operation in order to ensure the safety of patients' lives and effective treatment. To meet such requirements, sufficien...
