Description

Technical Field

[0001] The utility model relates to the technical field of medical imaging, in particular to a surgical instrument end marking system for medical guided focusing imaging. Background Art

[0002] In recent years, medical imaging equipment has been rapidly popularized and widely used in clinical medicine. During surgery, surgeons usually use medical imaging equipment to identify and image different tissues and imaging targets.

[0003] Marking the camera target can help improve the efficiency of focusing and tracking the camera target, but the existing technology usually directly marks the camera target. During the operation, since the camera target will constantly change or switch according to the operator, it is difficult to mark multiple camera targets. Therefore, the camera mode for marking human organs, tissues, fine structures, etc. is rarely used. At present, it mainly relies on the operator to manually adjust the focus multiple times, which is cumbersome and the camera process is discontinuous.

[0004] In response to the above defects, a patent with publication number CN 112861849 A proposes to construct a deep learning image library of intraoperative tissue for spinal deformity based on the Faster R CNN algorithm model by collecting images in the surgical field and marking the main areas in the surgical field. Then, the main features are extracted through the constructed algorithm, and the target position and category in the area are judged, and the camera focus is adjusted to shoot. Although this method does not mark the camera target and directly identifies the camera target features, the scheme has high requirements for the image acquisition device and processor, and because the characteristics of human organs, tissues, and fine structures are often complex, bleeding, edema and deformation during surgery often affect the image quality and change the characteristics of the camera target, so it is difficult to achieve efficient and continuous shooting.

[0025] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention. The present invention can be embodied in a variety of different forms and is not limited to the embodiments described herein.

[0026] like Figure 1 A schematic structural diagram of a surgical instrument end marking system for medically guided focused imaging in an embodiment of the utility model is shown.

[0027] The system includes: a surgical instrument 1, a surgical instrument end mark 2, and a camera module 3; wherein the surgical instrument end mark 2 is established at the end of the surgical instrument 1 and is set within the capture range of the camera module 3, so that the camera module 3 can capture image information of the surgical instrument end mark 2.

[0028] The surgical instrument 1 refers to the medical instrument used in clinical surgery. In addition to conventional surgical instruments, there are also some specialized instruments, such as ophthalmology, orthopedics, urology, obstetrics and gynecology, burns, plastic surgery, neurosurgery, cardiothoracic surgery and general surgery, etc. The surgical instrument 1 includes but is not limited to: sponge forceps, tissue forceps, mosquito hemostatic forceps, needle holding forceps, hemostatic forceps, ordinary dressing forceps, tissue forceps, surgical scissors, surgical knife handles, tissue scissors, suture removal scissors, periosteal strippers, negative pressure suction tubes and other instruments.

[0029] The shape, color, brightness, size and material of the surgical instrument end mark 2 can be set according to the needs to ensure that the camera module can recognize it without affecting the operation. The surgical instrument end mark 2 can be directly marked on the surgical instrument 1 or can be a separate marking structure. The material of the surgical instrument end mark is a sterile material that meets medical hygiene standards.

[0030] The camera module 3 is an automatic zoom lens with a focus adjustment function and an image capture capability, and also has a certain capture range. The camera module 3 photographs the surgical instrument end mark 2 set within the capture range. For example, the mark established at the end of the surgical instrument is set directly below the camera module.

[0031] In one embodiment, the marking form of the surgical instrument end mark 2 includes: one or more of a graphic mark, a brightness mark, a color mark, a morphological mark and a pattern mark. Specifically, the surgical instrument end mark 2 can be marked with different graphics, and the graphic is a vector map composed of external contour lines, that is, different shapes composed of drawn straight lines, circles, rectangles, and curves. The surgical instrument end mark 2 can be marked with different colors, which can be one color or a mixture of different colors. In order to facilitate identification, a single color is generally selected, such as blue, yellow, green and other colors. The surgical instrument end mark 2 can be marked in different forms, such as its own size, outline, shape and structural features. The surgical instrument end mark 2 can be marked with different patterns, and the pattern can be a specific pattern or a symbol mark.

[0032] In one embodiment, the surgical instrument end mark 2 can be directly marked on the surgical instrument 1. Specifically, the surgical instrument end mark 2 is a coating processed on the surface of the end of the surgical instrument by printing or spraying. The coating has different colors, graphics or patterns and is usually provided with the product when it leaves the factory.

[0033] In one embodiment, the surgical instrument end marker 2 may be an independent structure fixed to the end of the surgical instrument 1. The structural shape of the surgical instrument end marker may be spherical, square, sheet-like, or irregular.

[0034] For example, the surgical instrument end mark 2 can be an adhesive paper with different colors or patterns printed on the surface, which can be adhered to the end of the surgical instrument; the surgical instrument end mark 2 can be a metal sheet or plastic sheet with different colors or patterns printed on the surface, and fixed to the surface of the surgical instrument by buckling or sticking; the surgical instrument end mark 2 can be a three-dimensional structure of a set shape, which can be fixed on the end of the surgical instrument; the surgical instrument end mark 2 can be a three-dimensional structure with different colors or patterns printed on the surface, which can be fixed on the end of the surgical instrument; the surgical instrument end mark 2 can be a three-dimensional structure with different colors or patterns printed on the surface, which can be fixed on the end of the surgical instrument; the surgical instrument end mark 2 can be a three-dimensional structure with adhesive paper with different colors or patterns printed on the pasted surface, which can be fixed on the end of the surgical instrument.

[0035] The fixing method used for the surgical instrument end mark 2 can be set according to needs, such as bonding, bolt connection, welding, pin connection, and socket connection.

[0036] In one embodiment, the surgical instrument end marker 2 can be detachable or fixed to the end of the surgical instrument 1, so as to facilitate fixing the surgical instrument end marker 2 to the ends of different surgical instruments.

[0037] In one embodiment, the camera module 3 includes: one of a liquid lens module, a non-liquid lens module and a fixed-focus lens module.

[0038] Among them, the liquid lens in the liquid lens module adopts the electrowetting process to achieve excellent autofocus function. Two immiscible liquids, each with a different refractive index, are used to generate a variable focus lens that is the same as a traditional high-quality optical lens. Of the two liquids, one is a conductive aqueous solution and the other is a non-conductive oil. The two liquids are contained in a small tubular container, forming a crescent-shaped surface equivalent to a glass lens in the container, and the focal length of the liquid lens is adjusted by changing the curvature of the surface. The liquid lens is focused by controlling a layer of transparent liquid to form a nearly spherical lens after being acted on by an electric current between two electrodes, that is, by adjusting the DC voltage at both ends of the container, the crescent-shaped surface at the junction of the two different liquids can be changed.

[0039] The non-liquid lens module can use any automatic zoom lens except the liquid lens, such as a standard lens, a long and short focal length lens, etc. Among them, the traditional non-liquid lens achieves zoom by adjusting the relative position of the lens inside the lens.

[0040] The fixed-focus lens module may use a lens with a fixed focal length, such as a standard lens, a wide-angle lens, etc. The fixed-focus lens changes the clarity of the output image by adjusting the relative position of the camera and the object being photographed.

[0041] In one embodiment, the system further comprises: a control module, which is in communication with the camera module 3. The control module may be a common control device, which is used to generate a control signal and send it to the camera module 3 for focusing.

[0042] In one embodiment, if Figure 2 , the control device includes: an image memory 41, an image processor 42 and a focus control driving device 43; wherein the image memory 41 is connected to the image processor 42, and the image processor 42 is connected to the focus control driving device 43; the image memory 41 and the focus control driving device 43 are also connected to the camera module 3 respectively. The image memory 41 stores the image information collected from the camera module 3, the image processor 42 receives the image information stored in the image memory 41, and sends the focus control signal to the focus control driving device 43 to generate a drive signal, and then the focus control driving device 43 sends the drive signal to the camera module 3 to drive the camera module to focus.

[0043] In one embodiment, the focus control driving device 43 includes: a focus control input terminal 431 and a driving device 432; wherein the focus control input terminal 431 and the driving device 432 are electrically connected; and the driving device 432 is also connected to the camera module 3 and the image processor 42. The focus control parameter set is input from the focus control input terminal 431, and the driving device 432 converts the input signal of the focus control input terminal 431 and the focus control signal of the image processor 42 into a driving signal, and then transmits it to the camera module 3 for focusing.

[0044] In a specific embodiment, the focus control input terminal 431 is one of a keyboard, a mouse, a trackball, a click gun, a key, a button, a touch pad and a touch screen.

[0045] In a specific embodiment, the driving device 432 is a driving circuit board provided with a driving chip.

[0046] Specifically, if the camera module 3 is a liquid lens module, the driving chip can be a DA conversion chip or a liquid lens driving chip. If the driving circuit board contains a DA conversion chip, after receiving the input signal of the focus control input terminal 431 and the focus control signal of the image processor 42, the input signal is first converted into the number of bits required by the DA conversion chip, and the input DA conversion chip is converted into different voltage outputs, and then transmitted to the liquid lens module through the operational amplifier circuit, that is, through the difference in voltage, the shape of the crescent-shaped surface at the junction of the two liquids in the liquid lens is changed to complete the focusing process. For another implementation method, the driving circuit board contains a liquid lens driving chip. After the liquid lens driving chip receives the input signal of the focus control input terminal 431 and the focus control signal of the image processor 42, it controls the driving circuit board to output voltages of different sizes, and then transmits it to the liquid lens module, that is, through the difference in voltage, the shape of the crescent-shaped surface at the junction of the two liquids in the liquid lens module is changed to complete the focusing process. It should be noted that the DA conversion chip mentioned is a DA conversion chip commonly used in existing solutions, and the liquid lens driver chip adopts an existing liquid lens driver chip, and this solution does not improve the software algorithm. For example, the chip model used by the DA conversion chip is DAC0832, and the chip model used by the liquid lens driver chip is HV892.

[0047] If the camera module 3 is a non-liquid lens module, the driving chip uses an ordinary lens driving chip, and after receiving the input signal of the focus control input terminal 431 and the focus control signal of the image processor 42, the lens is driven to focus. It should be noted that the ordinary lens driving chip can use the lens driving chip commonly used in the existing solution, and the software algorithm is not improved in this solution. For example, the chip model is GC6236, GC6208 and GC6209.

[0048] In one embodiment, the image storage 42 of the present invention may be one or more devices for storing image information, which usually digitizes the information and then stores it in a medium using electrical, magnetic or optical means. The image storage 41 may be a storage device such as a solid state drive SSD, a USB flash drive, a memory card (such as an SD card, a TF card, a NM card and a CF card).

[0049] In one embodiment, the image processor 42 is a CPU, a GPU or an integrated chip with computing power, and the present solution does not improve the software algorithm here. The integrated chip can be a single chip microcomputer, an ARM, a CPLD, an FPGA or a DSP chip, etc. For example, the image processor adopts the model LM98519.

[0050] In summary, the utility model provides a surgical instrument end marking system for medically guided focusing and imaging, including: a surgical instrument, a surgical instrument end mark, and a camera module. The utility model establishes a mark at the end of the surgical instrument, places the mark within the capture range of the camera module, and uses the camera module to capture an image of the mark. The utility model converts the "camera target" into a "human-held surgical instrument end mark", which not only realizes the marking of the camera target during the operation, but also solves the problem of "the operator switching the target and the camera device being unable to recognize the target switch", and can assist in achieving continuous and efficient focusing. Therefore, the utility model effectively overcomes the various shortcomings of the prior art and has a high industrial application value.

[0051] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by a person with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
