Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a digestive endoscope support. BACKGROUND

[0002] The digestive endoscope (endoscope) is a tool commonly used for medical diagnosis and treatment, which can enter the body through the natural orifice or micro-incision of the body, and is used for observation, examination, tissue sample acquisition and surgical treatment. When performing a digestive tract examination, the endoscope is directly inserted into the patient's body for examination. However, due to the complex situation in the patient's body, the endoscope may sometimes be displaced, resulting in the use of the endoscope being out of control, and the use effect is generally not good. In order to facilitate the examination, a support is needed to assist the endoscope to work.

[0003] The endoscope support in the prior art is generally a straight sleeve, and the endoscope passes through the sleeve and enters the human body. However, the sleeve support can only provide lateral support for the endoscope, and cannot adjust or change the angle according to actual needs, thereby reducing the functionality of the endoscope and failing to meet more use requirements. In addition, the sleeve support lacks a sealing and isolating structure. After the endoscopic examination is completed, the endoscope needs to be separated from the sleeve support. At this time, the outer wall of the endoscope carries some body fluids such as gastric juice. These body fluids will be left in the sleeve support when the endoscope passes through the sleeve support, thereby polluting the inside of the sleeve support. In addition, when the endoscope enters the human body, the intestines will feel uncomfortable and will exert an outward pushing force on the endoscope through peristalsis. However, the existing sleeve support lacks a limiting measure to prevent the endoscope from retreating, so the medical staff need to frequently adjust the position of the endoscope, thereby increasing the labor of the medical staff.

[0028] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the concept of the present application, therefore the present application is not limited to the specific embodiments disclosed below.

[0029] EMBODIMENT REFERENCE Figures 1-10 For the embodiment of the present application, it comprises a digestive endoscope stent, which comprises a frame unit 1, the top end of the frame unit 1 is rotationally connected with an adjustment unit one 2, the adjustment unit one 2 is provided with an adjustment unit two 3, the inside of the frame unit 1 is provided with an auxiliary unit 4, the adjustment unit one 2 and the adjustment unit two 3 are fixedly connected together, so that the adjustment unit one 2 can drive the adjustment unit two 3 to rotate synchronously at the top end of the frame unit 1; COMBINED Figure 2 WITH Figure 4, the frame unit 1 includes a horn-shaped horn pipe 11, a sleeve 12 arranged below the horn pipe 11, and a gear ring 13 fixedly arranged at the top end of the horn pipe 11, the horn pipe 11, the sleeve 12 and the gear ring 13 are fixedly connected together, and the three are hollow inside, the endoscope 6 can pass through the shaft center of the three, the overall structure of the frame unit 1 is similar to a funnel, the structure of being thin at the bottom and thick at the top facilitates the placement in the natural hole of the human body, such as the oral cavity, and the structure of the horn pipe 11 and the sleeve 12 combined with each other can form a channel in the human body when placed in the human body, thereby facilitating the endoscope 6 to enter the inside of the human body, reducing the discomfort of the human body, and the structure of the frame unit 1 existing independently can conveniently carry out the endoscope 6 examination work and recovery, improve the work efficiency; In combination Figure 5 , the adjusting unit one 2 includes a sleeve ring 21 sleeved on the gear ring 13, a plurality of limiting teeth 24 distributed in the sleeve ring 21, and the limiting teeth 24 abut against the gear ring 13, a plurality of protrusions for increasing friction are arranged on the outer wall of the sleeve ring 21, thereby facilitating the rotation of the peristaltic sleeve ring 21 on the frame unit 1, the outer side of the limiting tooth 24 is provided with a bevel tooth matching the gear ring 13, the top end of the bevel tooth is smoothly transitioned, and the limiting tooth 24 is clamped with the gear ring 13 through the bevel tooth, which can provide a certain resistance to prevent the rotation of the sleeve ring 21; In combination Figure 6 , the adjusting unit two 3 includes a fixed ring 31 fixedly connected to the top end of the sleeve ring 21, an adjusting component 32 transversely arranged on the fixed ring 31, a shaft sleeve 33 threadedly connected to the adjusting component 32, and a ring frame 34 rotationally connected to the side surface of the shaft sleeve 33, the fixed connection of the fixed ring 31 and the sleeve ring 21 enables the adjusting unit two 3 to move synchronously with the sleeve ring 21, and the threaded connection of the adjusting component 32 and the shaft sleeve 33 enables the shaft sleeve 33 to drive the ring frame 34 to slide horizontally in a horizontal direction through threaded driving when the shaft sleeve 33 is limited in a vertical direction (i.e., when the endoscope 6 passes through the ring frame 34 in a vertical direction); In combination Figure 9 , the auxiliary unit 4 includes a ring-shaped frame 42 fixedly connected to the connection position of the horn pipe 11 and the sleeve 12, a spherical frame 41 rotationally arranged in the ring-shaped frame 42 and having a spherical structure, a conical block 43 fixedly connected to the lower end of the ring-shaped frame 42 and having an inverted conical structure, and a plurality of limiting components 44 equally arranged in the spherical frame 41, the spherical frame 41 is approximately spherical and can rotate around its center in the ring-shaped frame 42.

[0030] Among them, in combination, 2 and Figure 4The frame unit 1 also includes a limiting ring 14 fixedly connected to the top of the gear ring 13, and the adjustment unit 2 is connected to the gear ring 13 through the limiting ring 14 to limit the rotation. An inner upper bin 111 is opened inside the horn tube 11, and an inner lower bin 121 is opened inside the sleeve 12. The limiting ring 14 matches the limiting groove 22, which can limit the adjustment unit 2 as a whole to the frame unit 1, so that the adjustment unit 2 can rotate on the frame unit 1 without changing its position.

[0031] Among them, combined Figure 2 A disinfection layer 5 is matched with the inner upper warehouse 111, and the conical block 43 is located in the inner lower warehouse 121 as a whole. The disinfection layer 5 is made of a soft and water-absorbent material, and the endoscope 6 can pass through the disinfection layer 5 and extend into the spherical frame 41. Disinfection liquid, such as alcohol, iodine tincture, etc., is injected into the inner upper warehouse 111. The disinfection layer 5 can absorb these disinfection liquids. When the endoscope 6 passes through the disinfection layer 5, the disinfection layer 5 can further disinfect the outer wall of the endoscope 6 through the disinfection liquid absorbed by itself, and the disinfection layer 5 can be deformed by the pressure of the endoscope 6 when the angle of the endoscope 6 is adjusted, without hindering the normal disinfection operation of the endoscope 6.

[0032] Among them, combined Figure 5 The adjustment unit 2 also includes a limiting groove 22 provided on the collar 21, a mounting groove 23 provided on the inner wall of the collar 21 and corresponding to the limiting tooth 24, and a spring 25 arranged in the mounting groove 23, and the outer end of the spring 25 abuts against one side of the limiting tooth 24. The limiting groove 22 matches the limiting ring 14, and can limit the adjustment unit 2 to the top of the frame unit 1.

[0033] During use, combine Figure 7 and Figure 8 The spring 1 25 can push the limiting tooth 24 outward through elastic support, and the limiting tooth 24 is engaged with the gear ring 13 through its own bevel teeth, thereby limiting the collar 21 as a whole. However, when the collar 21 is subjected to a rotation force greater than the elastic force of the spring 1 25, the bevel teeth of the limiting tooth 24 will be misaligned with the gear ring 13, so that the limiting tooth 24 compresses the spring 1 25 and shrinks into the mounting groove 23. At this time, the limiting tooth 24 will not hinder the normal rotation of the collar 21. Therefore, when the digestive endoscope bracket is in use, only the medical staff can actively drive the The force that causes the ring 21 to rotate will be greater than the elastic supporting force of the spring 1 25, thereby breaking the limiting fixation of the ring 21 by the limiting tooth 24. When the medical staff stops operating, the limiting tooth 24 continues to be clamped on the gear ring 13 through the elastic support of the spring 1 25, thereby achieving the purpose of limiting and fixing the ring 21. After the angle of the endoscope 6 is adjusted in the circumferential direction of the ring 21, the ring 21 is fixed at the specified position, and the angle of the endoscope 6 is also fixed at the same time, thereby ensuring the working effect of the endoscope 6 when working and realizing the function of adjusting and stopping.

[0034] Wherein, in combination Figure 6 The adjusting component 32 includes a screw rod 321 arranged transversely in the fixed ring 31, an optical shaft 322 symmetrically arranged at both ends of the screw rod 321, and a rotating knob 323 fixedly connected to the outer end of the optical shaft 322. The optical shaft 322 has a smooth outer wall, and is in a rotating connection relationship with the fixed ring 31. In combination with the rotating knob 323 at both ends, the adjusting component 32 as a whole can be rotated on the fixed ring 31 without changing the position.

[0035] Further, in combination Figure 6 The shaft sleeve 33 is threadedly connected to the screw rod 321, and the side of the ring frame 34 is provided with a connecting shaft 341 extending into the shaft sleeve 33. The ring frame 34 is concentric and coaxial with the fixed ring 31. The screw rod 321 can drive the shaft sleeve 33 to move the ring frame 34 horizontally through the thread. Therefore, when the endoscope 6 is inserted into the ring frame 34, the shaft sleeve 33 can be driven to move the ring frame 34 to push the endoscope 6 horizontally by rotating the adjusting component 32, thereby achieving the purpose of adjusting the angle of the endoscope 6 in the horizontal direction. At the same time, the threadedly connected shaft sleeve 33 and the adjusting component 32 have a self-locking function, which can fix the endoscope 6 at a specified angle, effectively avoiding the phenomenon of accidental displacement and further ensuring the working accuracy.

[0036] Wherein, in combination Figure 9 The ring frame 42 has a circular ring structure, and the inner wall curvature of the circular ring matches the outer wall curvature of the spherical frame 41. The diameter of the top end of the circular ring of the ring frame 42 is smaller than the diameter of the spherical frame 41. Since the inner diameter of the top end of the ring frame 42 is smaller than the diameter of the spherical frame 41, the spherical frame 41 cannot be separated from the ring frame 42. However, the inner wall curvature of the ring frame 42 matches the outer wall curvature of the spherical frame 41, so the spherical frame 41 can rotate freely in the ring frame 42 with its center as the axis.

[0037] Further, in combination Figure 9The ball-shaped frame 41 is provided with a fixing groove 411 matched with the limiting component 44. The ball-shaped frame 41 is in communication with the shaft center position of the conical block 43 in the vertical direction and is provided with a channel 45 matched with the endoscope 6. In use, the endoscope 6 directly passes through the channel 45. The inverted conical conical block 43 can scrape the body fluid attached to the outer wall of the endoscope 6 when the endoscope 6 is reversely pulled away from the auxiliary unit 4 and diffuse outward to the inner lower bin 121 through the conical surface. The ball-shaped frame 41 cooperates with the ring-shaped frame 42 to separate the inner lower bin 121 from the inner upper bin 111. Therefore, the body fluid on the endoscope 6 is concentrated and removed in the inner lower bin 121, thereby avoiding the body fluid from entering the inside of the digestive endoscope support and ensuring the overall cleanliness of the inside of the support. When cleaning the device, the inner lower bin 121 is cleaned to achieve good cleaning effect, thereby improving the convenience of using the device.

[0038] Among them, in combination with Figure 9 The limiting component 44 is arranged in the fixing groove 411. The limiting component 44 includes a limiting wheel 441 rotatably connected in the fixing groove 411, a clamping block 442 arranged above the limiting wheel 441, a spring 443 arranged at the top end of the clamping block 442, and a plurality of rubber pads 444 distributed on the limiting wheel 441. The limiting wheel 441 is rotatably connected in the ball-shaped frame 41. A part of the limiting wheel 441 extends to the channel 45, thereby contacting the outer wall of the endoscope 6 inserted in the channel 45 and increasing the friction between the endoscope 6 and the limiting wheel 441 through the rubber pads 444. The spring 443 supports the clamping block 442 by elasticity and makes the clamping block 442 clamped on the limiting wheel 441, thereby limiting the limiting wheel 441 to a certain extent. The rubber pads 444 are made of rubber material and can be deformed when being pressed and contacted with the endoscope 6, thereby avoiding the endoscope 6 from being pinched and increasing the contact friction with the endoscope 6.

[0039] Further, in combination with Figure 9The locking groove 445 is connected with the side of the card block 442 by the steep slope edge 4452, so that the steep slope edge 4452 can exert a certain degree of resistance on the limiting wheel 441 when the limiting wheel 441 rotates in the opposite direction. When the force of the limiting wheel 441 rotating in the opposite direction is greater than the elastic force of the spring 443, the steep slope edge 4452 will squeeze and guide the card block 442 to move upward, and the card block 442 moving upward will no longer hinder the reverse rotation operation of the limiting wheel 441. In actual use, the endoscope 6 is normally inserted into the channel 45 from above. The limit wheel 441 rotates forward at this time and does not hinder the normal insertion of the endoscope 6. However, when the insertion of the endoscope 6 stops, the endoscope 6 is located in the human digestive tract. The reverse thrust of the digestive tract peristalsis will push the endoscope 6 to move upward. The upward movement causes the endoscope 6 to push the limit wheel 441 to rotate in the opposite direction. At this time, the elastic force of the spring 2 443 is greater than the thrust of the intestinal peristalsis, which will hinder the reverse rotation of the limit wheel 441 through the block 442, thereby preventing the endoscope 6 from being pushed out in the opposite direction, effectively preventing the backlash phenomenon from occurring, and ensuring the working effect. When the medical staff actively pulls out the endoscope 6, the pulling force is much greater than the elastic force of the spring 2 443, thereby causing the block 442 to move upward and compress the spring 2 443. At this time, the limit wheel 441 is no longer hindered and no longer limits the endoscope 6, so that the endoscope 6 can be smoothly pulled out of the channel 45.

[0040] In summary, combined Figure 6 and Figure 10 When using the digestive endoscope support, insert the endoscope 6 vertically into the ring frame 34, the disinfection layer 5 and the channel 45 in sequence (such as Figure 10 As shown), the endoscope 6 will be further disinfected when passing through the disinfection layer 5, and when the angle of the endoscope 6 needs to be adjusted; When the adjusting member 32 is rotated and driven, the sleeve 33 slides horizontally. At this time, the upper end of the endoscope 6 is sleeved on the ring frame 34. Therefore, the sleeve 33 will synchronously drive the upper end of the endoscope 6 to slide horizontally through the ring frame 34. The lower end of the endoscope 6 is located in the ring frame 42. Therefore, the angle of the endoscope 6 as a whole can be adjusted horizontally with the ball frame 41 as the center. Further, the sleeve 21 can also move the adjusting unit two 3 as a whole to rotate in the vertical direction, and the inner mirror 6 is inserted into the ring stand 34 in the adjusting unit two 3, so the sleeve 21 can further drive the inner mirror 6 to rotate in the vertical direction, and when the sleeve 21 drives the inner mirror 6 to rotate, the lower end of the inner mirror 6 will also rotate around the spherical stand 41 as the axis, achieving the purpose of adjusting the angle in the vertical direction. Through the mutual cooperation of the horizontal angle adjustment of the adjusting unit two 3 and the vertical angle adjustment of the adjusting unit one 2, the inner mirror 6 can be adjusted in multiple directions and multiple angles, fully meeting the use requirements and improving the flexibility of the device, and the adjusting sequence of the two adjusting units one 2 and two 3 is not fixed, and the operation sequence can be selected according to the actual requirements, further improving the flexibility of the device.

Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application, and they should be covered in the scope of the claims of the present application.
