[0044] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without creative efforts shall fall within the protection scope of the present utility model

[0045] The following will combine Figures 1 to 10 to describe in detail the orthopedic electronic endoscope and endoscope imaging system provided by the embodiments of the present utility model through specific embodiments and their application scenarios

[0046] In the first aspect, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , this embodiment provides an orthopedic electronic endoscope 1, including: a mirror tube 11, a mirror body 12, a handle 13, a plug 14 and an access sleeve

[0047] A handle 13 is provided on the mirror tube 11, a through image acquisition channel is formed in the mirror tube 11 and the handle 13, a mirror body 12 is installed at the front end of the image acquisition channel on the mirror tube 11, and the plug 14 is connected to the rear end of the mirror tube 11

[0048] The access cannula is sleeved on a section of the lens tube 11 between the lens body 12 and the handle 13. The access cannula includes a first cannula 15 and a second cannula 16, and the first cannula 15 and the second cannula 16 can be selectively installed on the lens tube 11.

[0049] Among them, the first cannula 15 is used for injecting platelet-rich plasma, and the second cannula 16 is used for flushing with water during the operation.

[0050] It can be understood that the lens tube 11 and the handle 13 are of a hollow structure. A connecting wire is provided in the image acquisition channel inside the lens tube 11 and the handle 13. One end of the connecting wire is connected to the lens body 12, and the other end is connected to the plug 14. The plug 14 can be directly plugged into the imaging device, and the plug 14 provides power supply and data transmission signals for the lens body 12.

[0051] The lens body 12 is used for observing and imaging the bone joints or spine in orthopedics. The lens body 12 is installed at the front end of the lens tube 11 and is transmitted back to the plug 14 through the connecting wire connected to the lens body 12.

[0052] The access cannula is sleeved on a section of the lens tube 11 for installing the lens body 12. The access cannula can provide a channel for the lens body 12 to enter the inside of the bone joint or the spine, and this channel can be used for imaging observation or treatment. Optionally, the access cannula can be selected as the first cannula 15 or the second cannula 16.

[0053] Specifically, the first cannula 15 can be used to inject platelet-rich plasma. An annular channel is formed between the inner wall of the first cannula 15 and the outer wall of the lens tube 11. The annular channel is communicated with the injection end of the platelet-rich plasma. The platelet-rich plasma is injected through the injection end and is input from the front end of the lens tube 11 into the bone joint or the spine, realizing the timely supply of plasma during the operation and contributing to the recovery of the wound.

[0054] The second cannula 16 can be used for flushing with water during the operation. An annular channel is formed between the inner wall of the second cannula 16 and the outer wall of the lens tube 11. The annular channel is communicated with the water inlet end and the water outlet end respectively. Clear water is injected through the water inlet end of the annular channel, and the clear water enters the annular channel, which can flush the operation site and the lens body 12 to ensure that the field of view during the operation is clearly visible.

[0055] Optionally, the waterproof level of the lens body 12 can be selected as IPX7 level, which can ensure that the lens body 12 is not affected by the liquid when injecting platelet-rich plasma or flushing with clear water.

[0056] The orthopedic electronic endoscope 1 provided by the present utility model sets the access cannula as the first cannula 15 and the second cannula 16 with different structures, and the first cannula 15 and the second cannula 16 can be selectively installed on the lens tube 11. When the first cannula 15 is installed, platelet-rich plasma can be injected into the bone joint or spine. When the second cannula 16 is installed, it can be used for water flushing during the operation. So during the operation, the access cannula can not only provide the installation channel for the lens tube 11, but also be used for injecting platelet-rich plasma or water flushing during the operation. It can not only supply plasma to the bone joint and spine, which is beneficial to wound recovery, but also flush the lens body 12 and the operation site, ensuring the clarity of the vision of the lens body 12 during the operation, realizing the multi-functional application of the access cannula, without drilling holes in the bone joint and spine again, reducing the pain of the patient and improving the efficiency of the operation on the bone joint and spine.

[0057] In some embodiments, as Figure 5 、 Figure 6 、 Figure 7 and Figure 8 shown, the first cannula 15 of this embodiment includes a first tube body 151, a first control valve 152 and a hose 153.

[0058] The first tube body 151 is sleeved on the lens tube 11, the first control valve 152 is installed at one end of the first tube body 151 close to the handle 13, the hose 153 is arranged on the inner wall of the first tube body 151 and extends along the axial direction of the first tube body 151. The first end of the hose 153 extends into the first control valve 152, and the second end of the hose 153 is flush with one end of the first tube body 151 close to the lens body 12.

[0059] It can be understood that the first tube body 151 is sleeved on a section of the lens tube 11 between the lens body 12 and the handle 13. One end of the first tube body 151 close to the handle 13 is provided with a first opening, and the first control valve 152 is communicated with the first opening.

[0060] The hose 153 is arranged in the annular channel formed by the lens tube 11 and the first tube body 151. One end of the hose 153 is communicated with the first control valve 152, and the first control valve 152 is communicated with the centrifugal instrument. The other end of the hose 153 extends into the front end of the lens tube 11, that is, the end of the lens tube 11 extending into the bone joint or spine. And the other end of the hose 153 is flush with one end of the lens body 12. During the operation, when platelet-rich plasma needs to be input to the patient, the first control valve 152 is opened, and platelet-rich plasma can be injected into the first control valve 152 by the centrifugal instrument in time. The platelet-rich plasma flows into the bone joint or spine through the hose 153. The dosage of platelet-rich plasma is accurately controlled by the centrifugal instrument. And the diameter of the hose 153 can be selected to be much smaller than the size of the gap of the annular channel. Based on the flexibility and non-fragility characteristics of the hose 153, accurate point-to-point delivery of platelet-rich plasma to the patient can be realized.

[0061] In some embodiments, as Figure 8 shown, the first sleeve 15 of this embodiment further includes a sealing ring 154.

[0062] An annular groove is provided on the inner wall of the first pipe body 151 near the handle 13. The annular groove is spaced from the first control valve 152, and the sealing ring 154 is arranged in the annular groove.

[0063] It can be understood that when the first pipe body 151 is sleeved on the outer wall of the lens tube 11, the sealing ring 154 is clamped between the first pipe body 151 and the lens tube 11. The sealing ring 154 is used to seal the inner wall of the first pipe body 151. When injecting platelet-rich plasma through the hose 153, if the platelet-rich plasma flows back into the first pipe body 151, the sealing ring 154 stops the platelet-rich plasma and prevents the platelet-rich plasma from flowing out from the handle 13, causing waste and pollution of the platelet-rich plasma.

[0064] Specifically, the sealing ring 154 can be an annular sealing ring, and the annular sealing ring can fit better with the annular groove to achieve a better sealing effect.

[0065] In some embodiments, as Figure 8 shown, the first sleeve 15 of this embodiment further includes a pipe joint 155.

[0066] The first end of the pipe joint 155 has an internal thread, and one end of the first pipe body 151 near the handle 13 has an external thread. The first end of the pipe joint 155 is threadedly connected to the first pipe body 151.

[0067] The second end of the pipe joint 155 is inserted into the handle 13.

[0068] It can be understood that when installing the first pipe body 151, the lens body 12 and the handle 13, the first pipe body 151 is sleeved on the lens tube 11 and slid to the handle 13 and inserted into the cavity of the handle 13, and then the pipe joint 155 is screwed onto the outer wall of the first pipe body 151 and tightened along the thread direction.

[0069] By providing the pipe joint 155 in this embodiment, when installing the first pipe body 151 and the handle 13, the first pipe body 151 and the handle 13 can be quickly installed and disassembled through the threaded connection between the first pipe body 151 and the pipe joint 155, which can not only ensure the tight connection after installation in place, but also achieve the flexible disassembly and assembly function.

[0070] In some embodiments, as Figure 6 shown, the first sleeve 15 of this embodiment further includes a positioning pin 156.

[0071] The inner wall of the pipe joint 155 is provided with a through hole, and the outer wall of the first pipe body 151 is provided with a mounting hole. The through hole and the mounting hole are arranged opposite to each other, and the positioning pin 156 is inserted into the mounting hole and the through hole.

[0072] It can be understood that in this embodiment, by arranging the positioning pin 156 to be inserted into the mounting hole and the through hole, the relative positions of the first pipe body 151 and the pipe joint 155 are fixed. During installation, the relative positions of the first pipe body 151 and the pipe joint 155 are characterized by the positioning pin 156, which can ensure the accurate alignment of the first pipe body 151 and the pipe joint 155 and convenient operation.

[0073] In some embodiments, such as Figure 9 shown, the second sleeve 16 of this embodiment includes a second pipe body 161, a second control valve 162, and a third control valve 163.

[0074] The second pipe body 161 is sleeved on the mirror tube 11, and the second control valve 162 and the third control valve 163 are respectively installed at one end of the second pipe body 161 close to the handle 13.

[0075] Among them, the second control valve 162 is used to control the water inlet during the operation, and the third control valve 163 is used to control the water outlet during the operation.

[0076] It can be understood that the second pipe body 161 is sleeved on a section of the mirror tube 11 between the mirror body 12 and the handle 13. One end of the second pipe body 161 close to the handle 13 is provided with a second opening and a third opening. One end of the second control valve 162 is communicated with the second opening, and the other end of the second control valve 162 is communicated with the water source to control the water inlet. One end of the third control valve 163 is communicated with the third opening, and the other end of the third control valve 163 is communicated with the collection assembly to control the water outlet. The water inlet and the water outlet together realize the flushing of the affected area and the mirror body 12 during the operation.

[0077] Furthermore, the second control valve 162 and the third control valve 163 can be respectively arranged on two straight lines intersecting the outer wall of the second pipe body 161 along the radial direction of the second pipe body 161. The second control valve 162 and the third control valve 163 are arranged opposite to each other along the axial direction of the second pipe body 161, which can ensure that the water inlet end and the water outlet end are on a straight line, reduce the resistance of the water inlet and the water outlet, and is beneficial to realizing rapid flushing.

[0078] In some embodiments, such as Figure 3 and Figure 10 shown, one end of the mirror tube 11 for installing the mirror body 12 is inclined, and the viewing angle of the mirror body 12 is 30°.

[0079] It is understandable that the viewing angle of the lens body 12 is 30°, that is, the angle α between the perpendicular line of the inclined surface of the lens body 12 and the axis of the lens tube 11 is 30°. When the lens body 12 is rotated within the bone joint or spine, compared with the lens body 12 with an angle of 0°, the lens body 12 with an angle of 30° has a larger viewing range, and surgical instruments can be placed at different angles for operation without blocking the line of sight, which is more conducive to observing the affected area through the lens body 12 during the operation.

[0080] In some embodiments, the lens body 12 of this embodiment is made of polycarbonate.

[0081] It is understandable that the lens body 12 is made of polycarbonate. Compared with sapphire parts, the imaging of polycarbonate parts is clearer. At the same time, polycarbonate parts are more wear-resistant, which is beneficial to the accurate imaging of the affected area.

[0082] In some embodiments, the lens body 12 of this embodiment is provided with six LED light sources.

[0083] It is understandable that the lens body 12 uses six LED light sources. The six LED light sources are arranged at the front end of the lens body 12 and are evenly arranged along the circumferential direction of the lens body 12, which improves both the brightness and the clarity.

[0084] In some embodiments, such as Figure 1 and Figure 2 shown, the shape of the handle 13 of this embodiment conforms to ergonomics, which is convenient for grasping and operating.

[0085] It is understandable that the shape of the handle 13 of this embodiment adopts an ergonomic design. When in use, it is more comfortable to hold and operate, and it is not easy to slip from the hand, which is beneficial to the reliability and stability of the operation.

[0086] Second, in some embodiments, such as Figure 1 and Figure 2 shown, this embodiment provides an endoscopic imaging system, including: an imaging device 2 and an orthopedic electronic endoscope 1.

[0087] The orthopedic electronic endoscope 1 is connected to the imaging device 2.

[0088] Specifically, since the endoscopic imaging system includes the orthopedic electronic endoscope 1, and the specific structure of the orthopedic electronic endoscope 1 refers to the above embodiments, the endoscopic imaging system shown in this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects obtained by all the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0089] It is understandable that the orthopedic electronic endoscope 1 is connected to the imaging device 2 through the plug 14. The imaging device 2 can display the images of joints or spine collected by the endoscope body 12 in real time during the operation, realizing the visualization of the operation, which is more conducive to the fine operation of the doctor during the operation and improves the quality of joint and spine operations.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
