For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] Before minimally invasive laparoscopic surgery, in order to penetrate the skin tissue to place the sleeve seat and provide a channel for surgical instruments, it is necessary to use a puncture needle to puncture the skin tissue in advance. The field of view provided by the puncture needle of the prior art is affected by the conical shape and puncture blade of the tip of the puncture needle. The image provided by the camera 105 is severely distorted and deformed, and cannot reflect the real image in front of the puncture needle. In addition, in the prior art, since the front end of the camera 105 is not shielded or protected, the lens will be fogged or contaminated when entering the skin tissue, resulting in poor image quality, prolonged operation time, and increased surgical risks.

[0030] In order to solve the above technical problems, an embodiment of the present application provides a laparoscope card puncture device 100.

[0031] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, the embodiment of the present application provides a laparoscope card puncture device 100, including an operating rod 101, a puncture head 102 and a camera assembly 103; the camera assembly 103 includes a connecting rod 104 and a camera 105, the first end 106 of the connecting rod 104 is connected to the end of the operating rod 101, and the second end 107 of the connecting rod 104 is installed with the puncture head 102; a bearing structure 108 for installing the camera 105 is provided on the connecting rod 104, and the bearing structure 108 is connected to the connecting rod 104 through a rotating assembly. The rotation axis of the rotating assembly is perpendicular to the puncture direction 109 of the puncture head 102, and the bearing structure 108 can be driven to drive the camera 105 to rotate, so as to adjust the angle between the camera 105 and the puncture direction 109 of the puncture head 102.

[0032] It should be noted that the laparoscope puncture device 100 provided in the embodiment of the present application can be used for laparoscopic and other surgeries, and can provide a continuous field of view for the surgeon during the operation, while improving the efficiency of the entire surgical team, reducing the need for a separate laparoscope and a laparoscopic doctor, and allowing simultaneous observation of the surgical area, simplifying all professional laparoscopic surgeries. At the same time, it allows the surgeon to control autonomously, always ensuring that the surgeon is within the field of view of the leading surgeon of the surgical operation.

[0033] It should be noted that the laparoscope puncture device 100 provided in the embodiment of the present application is easy to operate. The user can control the movement of the puncture head 102 and the camera assembly 103 by operating the lever 101. When the puncture head 102 passes through the skin tissue, the camera 105 can be buckled on the connecting rod 104 through the supporting structure 108, that is, the camera 105 is rotated toward the direction close to the connecting rod 104 through the supporting structure 108, thereby avoiding fogging and contamination of the camera 105 when passing through the skin tissue, and facilitating obtaining high-quality shooting images when the camera 105 is rotated and opened.

[0034] The embodiment of the present application provides a laparoscope card poking and puncturing device 100, comprising an operating rod 101, a puncture head 102 and a camera assembly 103; the camera assembly 103 of the embodiment of the present application comprises a connecting rod 104 and a camera 105, a first end 106 of the connecting rod 104 is connected to the end of the operating rod 101, and the puncture head 102 is installed on the second end 107 of the connecting rod 104, and the operating rod 101 can be used to drive the puncture head 102 to perform card poking and puncturing.

[0035] In the embodiment of the present application, a bearing structure 108 for mounting a camera 105 is provided on the connecting rod 104. The bearing structure 108 is connected to the connecting rod 104 via a rotating assembly. The rotation axis of the rotating assembly is perpendicular to the puncture direction 109 of the puncture head 102. The bearing structure 108 can be driven to drive the camera 105 to rotate, thereby adjusting the angle between the camera 105 and the puncture direction 109 of the puncture head 102.

[0036] In the embodiment of the present application, the camera 105 is driven to rotate by the supporting structure 108, so that the camera 105 can approach or move away from the puncture head 102 along the rotation arc, so that the puncture head 102 can be photographed from different angles, allowing medical operators to more accurately and comprehensively understand the situation in front of the puncture head 102.

[0037] In addition, the embodiment of the present application can make the head of the camera 105 engage with the surface of the connecting rod 104 through the rotation of the supporting structure 108, thereby preventing the camera 105 from being directly exposed to the outside, thereby effectively avoiding the fogging of the camera 105 lens or the contamination of the camera 105 lens caused by the skin tissue during the card puncture process, greatly improving the image quality, and helping to shorten the operation time and reduce the surgical risk.

[0038] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, as an optional embodiment, the connecting rod 104 has a receiving groove 110 whose extension direction is consistent with the puncture direction 109, and the rotating assembly is arranged at the end of the receiving groove 110 away from the puncture head 102; the supporting structure 108 includes a strip structure member, the strip structure member can be embedded in the receiving groove 110, and the camera 105 is arranged on one side of the strip structure member close to the bottom of the receiving groove 110.

[0039] The embodiment of the present application can accommodate the bearing structure 108 by providing a receiving groove 110 on the connecting rod 104, so that the camera 105 and the bearing structure 108 can be embedded in the receiving groove 110. On the one hand, it can improve the protection performance of the camera 105, and on the other hand, it can avoid that the bearing structure 108 and the camera 105 have a large protrusion on the surface of the connecting rod 104, which is not conducive to the puncture of the puncture head 102, thereby avoiding causing greater trauma to the patient's skin tissue.

[0040] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, as an optional implementation, when the strip structure is embedded in the accommodating groove 110 , the surface of the strip structure away from the camera 105 is flush with the surface of the connecting rod 104 .

[0041] More preferably, in the embodiment of the present application, the strip structure is embedded in the accommodating groove 110 , and the outer surface of the strip structure is flush with the surface of the connecting rod 104 , so that the side of the connecting rod 104 can form a smooth surface to facilitate puncture by the puncture head 102 .

[0042] It should be noted that the specific structure of the connecting rod 104 and the strip-shaped structural member can be set by those skilled in the art as required, and no special limitation is made thereto.

[0043] Exemplarily, the connecting rod 104 is a cylindrical rod, and a receiving groove 110 is provided on one side of the cylindrical rod, and the opening of the receiving groove 110 faces away from the central axis of the cylindrical rod. The strip structure can be embedded in the receiving groove 110, and the end of the strip structure away from the puncture head 102 is rotatably connected to the receiving groove 110, and when driven, it can drive the camera 105 to rotate.

[0044] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, as an optional implementation, the supporting structure 108 is further provided with a lighting assembly 111 , and the lighting assembly 111 and the camera assembly 105 are located on the same side of the supporting structure 108 .

[0045] The embodiment of the present application can perform white light illumination through the illumination assembly 111, wherein the camera 105 can be a fluorescent illumination camera 105. It should be noted that the camera 105 can be connected to the camera 105 through a video transmission line passing through the inner cavity of the operating rod 101, so that the camera 105 shooting signal is transmitted to an external display screen.

[0046] As an optional implementation, an operating portion 112 is provided at the end of the operating rod 101 away from the puncture head 102 , and a driving assembly connected to the rotating assembly is provided on the operating portion 112 .

[0047] Reference Figure 2 As shown, exemplarily, the driving assembly includes an operating handle 113 rotatably disposed on the operating portion 112 , and the operating rod 101 has a cavity therein, in which a traction transmission member 114 is disposed, one end of which is connected to the operating handle 113 and the other end of which is connected to the rotating assembly.

[0048] The traction transmission member 114 is a push-pull rod or a pull wire.

[0049] As an optional implementation, on a plane perpendicular to the rotation axis, an angle between an extension direction of the strip structure and an extension direction of the connecting rod 104 is 0-45°.

[0050] The central axes of the operating rod 101, the puncture head 102 and the connecting rod 104 coincide with each other.

[0051] It should be noted that the laparoscope card puncture device 100 provided in the embodiment of the present application can be manufactured at a low cost and can be used as a disposable device. It mainly includes a puncture head 102, a high-definition camera 105 with white light illumination (820mm fluorescent illumination), an operating handle 113 of the camera 105, and a video transmission line. During use, when the puncture head 102 is completely inserted into the human body, the surgeon moves the operating handle 113, and then lifts the camera 105 through the transmission structure, and then withdraws the puncture device to establish a card.

[0052] During specific use, the camera 105 can be freely switched between white light or fluorescent light as needed.

[0053] When the puncture head 102 and the connecting rod 104 are completely inserted into the human body, the surgeon lifts the operating handle 113, and then drives the camera 105 to lift up through the traction transmission member 114, observes the puncture environment comprehensively, and withdraws the puncture head 102 after precise operation, so that a puncture card can be established in the human body, so that the surgeon can control the scope of the surgical field of view. At the same time, ICG is a relatively non-toxic fluorescent dye, which has no toxic side effects when used without allergic reactions and at a concentration below 2.0 mg / kg (body weight). It is mainly decomposed and metabolized by the liver and excreted from the body through the biliary system, with a half-life of 3 to 4 minutes, and can be completely metabolized within 10 to 20 minutes after entering the blood. Because ICG has unique fluorescence characteristics, its emission wavelength is 750 to 820 nm, and the fluorescence wavelength released after excitation is 840 nm. Based on this principle, fluorescence excitation and fluorescence reception and development are integrated to realize fluorescence imaging of ICG. In this way, the surgeon controls the camera 105 device to switch freely between white light and fluorescence.
