[0005] The utility model discloses the following advantages after adopting the above technical scheme: first, the sleeve ring can rotate freely around the communication seat, so that the positions of the liquid inlet valve and the liquid outlet valve can be adjusted according to the use requirements, and the adjustment is no longer limited to the fixed positions, the obstruction of the liquid inlet valve and the liquid outlet valve to the use is reduced, secondly, the communication seat and the outer sheath are fixedly connected, and the communication seat does not rotate, thereby reducing the interference with the stability of the outer sheath, by arranging the liquid inlet and the liquid outlet on the communication seat and allowing the sleeve ring to rotate relatively independently, the risk of overall structure shaking caused by adjusting the positions of the liquid inlet valve and the liquid outlet valve is reduced, which helps to improve the stability of the image and the accuracy of the operation, which also means that the electrical cables or optical imaging systems inside the optical tube and the instrument tube will not be affected by the rotation of the sleeve ring. In this way, the problems of cable twisting or knotting or poor imaging quality caused by sleeve ring operation can be avoided as much as possible.

[0006] Further, the communication seat includes a first part in communication with the liquid inlet channel and a second part in communication with the instrument tube, the inner ring of the first part of the communication seat is spaced apart from the optical tube and the instrument tube, and the inner ring of the second part of the communication seat is in abutment with the optical tube and the instrument tube, and the inner ring of the communication seat is provided with a plug separating the first part and the second part.

[0007] By adopting the foregoing technical scheme, in the first part, the inner ring of the communication seat is spaced apart from the optical tube and the instrument tube, providing space for the liquid output by the liquid inlet channel, in the second part, the inner ring of the communication seat is in abutment with the optical tube and the instrument tube, providing more stable support for the optical tube and the instrument tube, so as to ensure that the optical tube and the instrument tube remain stable during use as much as possible, reducing unnecessary movement, and by arranging the plug inside the communication seat to separate the liquid inlet channel and the instrument tube, not only the physical isolation effect is achieved, the mixing or backflow of liquid between different channels is avoided as much as possible, but also the stability of the overall communication seat structure is helped, the risk of component displacement or leakage caused by liquid pressure change is reduced, and the overall reliability and durability of the equipment are improved.

[0008] Further, the sleeve ring is provided with a gripping groove facilitating gripping or the surface of the sleeve ring is provided with an anti-skid member.

[0009] By the above technical scheme, by arranging the gripping groove or the anti-skid member on the sleeve ring, the gripping groove or the anti-skid member provides better hand feeling and friction, and the operator can firmly hold the sleeve ring for adjustment with small force, so that the operation can be completed without applying excessive external force, avoiding additional pressure or vibration on the surgical equipment, further preventing the shaking of the internal components, and reducing accidental rotation caused by slippery hands or unstable operation, thereby reducing the shaking of the outer sheath and the internal components caused by unnecessary rotation of the sleeve ring.

[0010] Further, the outer ring of the communication seat is sleeved with a sealing ring separating the liquid inlet and the liquid outlet, and the inner wall of the sleeve ring is attached to the sealing ring.

[0011] By the foregoing technical solution, the sealing ring sleeved on the outer ring of the communication seat separates the liquid inlet and the liquid outlet, so as to prevent the mixing or leakage of the liquid at the communication seat as much as possible. In addition, the inner wall of the sleeve ring is attached to the sealing ring, which further strengthens the sealing effect and ensures that the liquid can flow along the established channel during the liquid inlet and outlet of the hysteroscope as much as possible. The presence of the sealing ring also makes the rotation between the sleeve ring and the communication seat smoother and more stable.

[0012] Further, the two sides of the liquid inlet and the two sides of the liquid outlet are provided with the sealing ring, the annular liquid inlet groove is formed between the two sealing rings on the two sides of the liquid inlet, the opening of the liquid inlet valve is located in the annular liquid inlet groove, the annular liquid outlet groove is formed between the two sealing rings on the two sides of the liquid outlet, and the opening of the liquid outlet valve is located in the annular liquid outlet groove.

[0013] By the foregoing technical solution, the annular liquid inlet groove is formed by arranging the sealing ring on the two sides of the liquid inlet, and the annular liquid outlet groove is formed by arranging the sealing ring on the two sides of the liquid outlet. Even if the sleeve ring rotates, the liquid inlet valve and the liquid outlet valve can still keep in communication with the liquid inlet and the liquid outlet respectively, so as to ensure that the liquid flow will not be interrupted no matter how the sleeve ring rotates and adjusts the position.

[0014] Further, the optical tube is located above the instrument tube and divides the liquid inlet channel into left and right parts, and the liquid inlet communicates the liquid inlet channels on the left and right parts.

[0015] By the foregoing technical solution, the liquid inlet channel on the left and right parts is communicated by arranging a common liquid inlet, so as to ensure that the liquid on both sides can be smoothly input even under the physical limitation of the optical tube and the instrument tube, thereby avoiding the problem of poor infusion caused by the blockage or uneven flow of the single channel as much as possible.

[0016] Further, the left and right sides of the communication seat are provided with two independent liquid inlets; or the outer sheath is provided with a liquid inlet covering the left and right side regions of the outer sheath.

[0017] By the foregoing technical solution, by arranging independent liquid inlets on the left and right sides of the communication seat, bilateral simultaneous liquid inlet can be realized, and the flowability problem caused by the separation can be solved. Or even if the liquid inlet channel is divided into left and right parts by the optical tube and the instrument tube, by arranging a large liquid inlet covering the left and right side regions on the outer sheath, the two parts of the channel can be directly communicated, so as to ensure that all the liquid can be smoothly input, and the flowability problem caused by the separation can be solved.

[0018] Further, the liquid inlet extends along the circumferential direction of the communication seat.

[0019] Through the technical scheme, the liquid inlet extends along the circumferential direction of the communication seat, so that the liquid inlet area is greatly increased, and the liquid inlet valve and the liquid inlet are directly connected as much as possible during the rotation of the sleeve ring.

[0020] Further, the area of the liquid outlet is greater than the area of the liquid inlet.

[0021] Through the technical scheme, the discharged liquid usually contains impurities such as blood and tissue debris.

[0022] Further, the optical tube includes an image channel and a light beam channel, and the hysteroscope further includes a mirror port in communication with the image channel and a light beam interface in communication with the light beam channel, and the mirror port and the light beam interface are located on the same side of the mirror body.

[0023] Through the technical scheme, the mirror port and the light beam interface are concentrated on one side, without the need to frequently change the holding posture or find the positions of the mirror port and the light beam interface. This not only improves the operation efficiency, but also increases the stability during operation, and reduces the device vibration or displacement that may be caused by frequent adjustment.

[0043] The technical scheme of the present application will be described in detail below with specific examples. The following specific examples can be combined or replaced according to actual conditions, and the same or similar concepts or processes may not be described in some examples.

[0044] As shown in Figures 1 to 12 The present application provides an intrauterine endoscope, which comprises a mirror body 10, an outer sheath 20, a communication seat 30, an optical tube 40 and an instrument tube 50. The outer sheath 20 is fixedly connected with the mirror body 10 through the communication seat 30. The optical tube 40 and the instrument tube 50 pass through the communication seat 30 and the outer sheath 20. The area outside the optical tube 40 and the instrument tube 50 in the outer sheath 20 is provided with a liquid inlet channel 21. The communication seat 30 is provided with a liquid inlet 33 communicating with the liquid inlet channel 21 and a liquid outlet 34 communicating with the instrument tube 50. A sleeve ring 60 is installed on the communication seat 30. The sleeve ring 60 is provided with a liquid outlet valve 62 and a liquid inlet valve 61. The liquid inlet valve 61 communicates with the liquid inlet 33, and the liquid outlet valve 62 communicates with the liquid outlet 34. The sleeve ring 60 is rotatably sleeved on the communication seat 30.

[0045] Firstly, the collar 60 can rotate freely around the communication seat 30, so that the positions of the liquid inlet valve 61 and the liquid outlet valve 62 can be adjusted according to the use requirements, and are no longer limited to fixed positions, reducing the obstruction of the liquid inlet valve 61 and the liquid outlet valve 62 to use. Secondly, the communication seat 30 and the outer sheath 20 are fixedly connected, and the communication seat 30 itself does not rotate, thereby reducing the interference with the stability of the outer sheath 20. By arranging the liquid inlet 33 and the liquid outlet 34 on the communication seat 30 and allowing the collar 60 to rotate relatively independently, the risk of overall structure shaking caused by adjusting the positions of the liquid inlet valve 61 and the liquid outlet valve 62 is reduced, which helps to improve the stability of the image and the precision of the operation. This also means that the electrical cables or optical imaging systems inside the optical tube 40 and the instrument tube 50 will not be affected by the rotation of the collar 60. In this way, the problems of cable twisting or knotting or poor imaging quality caused by the operation of the collar 60 can be avoided as much as possible.

[0046] It should be noted that the ends of the optical tube 40 and the instrument tube 50 away from the scope 10 and the end of the outer sheath 20 are flush, and the end of the instrument tube 50 away from the scope 10 and the end of the outer sheath 20 away from the scope 10 are provided with a bevel 22, so that the outer sheath 20 is more smooth when inserted into the body, reducing the damage to the tissue during the insertion of the outer sheath 20 into the body. The outlet of the instrument tube 50 and the inlet of the liquid inlet channel 21 are arranged on the bevel 22, facilitating the suction and discharge of the liquid, and the circumferential surface of the end of the outer sheath 20 away from the scope 10 is complete, without the inlet of the liquid inlet channel 21.

[0047] It should be noted that the endoscope of the embodiment has a glass optical imaging system.

[0048] Further, the communication seat 30 includes a first part 31 communicating with the liquid inlet channel 21 and a second part 32 communicating with the instrument tube 50. The inner circle of the communication seat 30 of the first part 31 is spaced apart from the optical tube 40 and the instrument tube 50, providing a channel for the liquid input by the liquid inlet channel 21. The inner circle of the communication seat 30 of the second part 32 is in close contact with the optical tube 40 and the instrument tube 50, providing more stable support for the optical tube 40 and the instrument tube 50, and ensuring that the optical tube 40 and the instrument tube 50 remain stable during the operation as much as possible, reducing unnecessary movement. The liquid inlet 33 is located in the first part 31, and the liquid outlet 34 is located in the second part 32. The surface of the instrument tube 50 is provided with a through hole 51 communicating with the second part 32.

[0049] In order to further reduce the amplitude of the overall structure shaking, the sleeve 60 is provided with a gripping groove 63 for easy gripping, which can provide a precise point of force for the fingers, so that the medical staff can exert force more stably and powerfully when rotating the sleeve 60 to adjust the angle, and the operator can firmly grasp the sleeve 60 for adjustment with less force, which can complete the operation without applying too much external force, avoid causing additional pressure or vibration to the surgical equipment, further prevent the shaking of the internal components, and reduce the accidental rotation caused by slippery hands or unstable operation, thereby reducing the shaking of the sheath 20 and internal components caused by unnecessary rotation of the sleeve 60.

[0050] In order to increase the sealing performance, the inner ring of the communication seat 30 is provided with a plug 70 separating the first part 31 and the second part 32, which not only plays a physical isolation role to avoid mixing or backflow of liquid between different channels as much as possible, but also helps to stabilize the overall structure of the communication seat 30, reduces the risk of component displacement or leakage caused by changes in liquid pressure, and improves the overall reliability and durability of the equipment.

[0051] Further, the outer ring of the communication seat 30 is provided with a sealing ring 80 separating the liquid outlet 34 and the liquid inlet 33, and the inner wall of the sleeve 60 is in close contact with the sealing ring 80 to prevent mixing or leakage of the inlet and outlet liquid at the communication seat 30 as much as possible. In addition, the inner wall of the sleeve 60 is in close contact with the sealing ring 80, which further enhances the sealing effect and ensures that the liquid flows along the established channel during the liquid inlet and outlet process of the hysteroscope as much as possible. The presence of the sealing ring 80 also makes the rotation between the sleeve 60 and the communication seat 30 smoother and more stable.

[0052] Among them, the two sides of the liquid outlet 34 and the two sides of the liquid inlet 33 are provided with sealing rings 80, and the two sealing rings 80 on the two sides of the liquid inlet 33 form an annular liquid inlet groove 36, and the opening of the liquid inlet valve 61 is located in the annular liquid inlet groove 36. The two sealing rings 80 on the two sides of the liquid outlet 34 form an annular liquid outlet groove 35, and the opening of the liquid outlet valve 62 is located in the annular liquid outlet groove 35. Even if the sleeve 60 rotates, the liquid inlet valve 61 and the liquid outlet valve 62 can still communicate with the liquid outlet 34 and the liquid inlet 33 respectively, which can ensure that the liquid flow will not be interrupted no matter how the sleeve 60 rotates and adjusts the position.

[0053] Since the optical tube 40 is located above the instrument tube 50 and divides the liquid inlet channel 21 into left and right parts, in order to solve the problem of flow caused by separation, in this example, the liquid inlet 33 communicates with the left and right parts of the liquid inlet channel 21, which can ensure that even under the physical limitation of the optical tube 40 and the instrument tube 50, the liquid on both sides can be smoothly input into the body, thereby avoiding the problem of poor infusion caused by unilateral channel blockage or uneven flow as much as possible.

[0054] Specifically, the left and right sides of the communication seat 30 are provided with two independent liquid inlets 33, which can realize simultaneous infusion on both sides and solve the flow problem caused by separation.

[0055] The liquid input into the body is usually normal saline, and in the present application, the liquid inlet 33 extends along the circumferential direction of the communication seat 30, so that the liquid inlet area is greatly increased, and as much as possible, the liquid inlet valve 61 and the liquid inlet 33 are directly connected during the rotation of the sleeve 60.

[0056] And the liquid discharged from the body usually contains blood, tissue debris and other impurities in addition to normal saline. Further, the area of the liquid outlet 34 is larger than that of the liquid inlet 33, and if the liquid outlet 34 is too small, these impurities may cause blockage, affecting the normal discharge of the liquid. The larger liquid outlet 34 can reduce the risk of such blockage and ensure that the liquid and impurities can be smoothly discharged.

[0057] In addition, the optical tube 40 includes an image channel 41 and a light beam guide channel 42, and the hysteroscope further includes a mirror port 11 in communication with the image channel 41 and a light beam guide interface 12 in communication with the light beam guide channel 42, and the mirror port 11 and the light beam guide interface 12 are located on the same side of the mirror body 10. The mirror port 11 and the light beam guide interface 12 are concentrated on one side, without the need to frequently change the holding posture or find the positions of the mirror port 11 and the light beam guide interface 12, which not only improves the operation efficiency, but also increases the stability during operation, and reduces the device vibration or displacement caused by frequent adjustment.

[0058] It can be understood that in other embodiments, the surface of the sleeve is provided with an anti-skid member, which increases the friction between the surface of the sleeve and the hand, so that even if the medical staff's hands sweat during the operation, the sleeve can be stably gripped, and the sleeve can be rotated to the right position or over-rotated due to the sliding of the hands.

[0059] It can be understood that in other embodiments, the outer sheath is provided with a liquid inlet covering the left and right side regions of the outer sheath, which can directly connect the two parts of the channel and ensure that all the liquid can be smoothly discharged, solving the flow problem caused by separation.

[0060] In addition to the above preferred embodiments, the utility model also has other implementation manners, and all other embodiments obtained by those skilled in the art without creative labor based on the embodiments in the utility model belong to the scope of the utility model.
