Description

Technical Field

[0001] The present invention relates to the technical field of gastroscopy auxiliary equipment, and in particular to a gastroscopy traction device. Background Art

[0002] Gastroscopy (EGD), also known as upper gastrointestinal endoscopy or esophagogastroduodenoscopy, is a medical diagnostic procedure used to directly observe the internal conditions of the esophagus, stomach, and duodenum. Gastroscopy is one of the important diagnostic methods that can accurately understand the patient's upper gastrointestinal tract condition so that necessary treatment measures can be taken.

[0003] Gastroscopy is performed using a soft, slender tube-type endoscope with a camera. After the examination is completed, the endoscope will be slowly withdrawn from the patient's body. Currently, this operation is generally performed by the doctor who performs the examination. The endoscope is withdrawn from the patient's body and placed in the instrument tray. At this time, the endoscope contaminated with the patient's body fluids may pollute the environment, shorten the life of the equipment, or even cause cross infection.

[0004] From the above technical content, it can be seen that the process of manually removing the gastroscope from the patient's body is prone to problems such as environmental pollution and cross infection. Summary of the invention

[0005] In view of this, the present invention aims to propose a gastroscope traction device, which can smoothly and evenly retract the endoscope channel after the gastroscopy is completed, and at the same time clean and disinfect the outer wall of the endoscope channel to reduce the risk of cross contamination and increase the service life of the instrument.

[0006] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0007] A gastroscope traction device comprises a mounting seat;

[0008] A drive assembly, detachably disposed on the mounting seat;

[0009] A cleaning assembly is rotatably disposed on the mounting seat and connected to the driving assembly;

[0010] A traction assembly, fixedly disposed on the mounting seat and connected to the driving assembly;

[0011] The cleaning component and the traction component can clean, clamp and pull the gastroscope tube under the action of the driving component:

[0012] Further, the traction assembly includes a worm, one end of which is connected to the drive assembly;

[0013] a turbine, meshing with the worm;

[0014] A driving wheel, fixed relatively to the turbine and coaxially arranged;

[0015] The clamping wheel is rotatably arranged on one side of the driving wheel around its own axis.

[0016] Furthermore, the traction assembly also includes a box body, which is detachably arranged on the mounting seat and covers the outer sides of the turbine and the worm.

[0017] Furthermore, the clamping wheel is slidably arranged on the box body along a direction approaching or moving away from the axis of the driving wheel, and the clamping wheel can be fixed at any position within a sliding stroke between the clamping wheel and the box body.

[0018] Furthermore, the traction assembly further comprises a guide plate vertically arranged on the upper surface of the box body;

[0019] The distance between the side of the guide plate facing the driving wheel and the axis of the driving wheel is equal.

[0020] Furthermore, the traction assembly also includes a hand wheel, which is detachably mounted on an end of the worm away from the driving assembly.

[0021] Further, the cleaning assembly includes a support arm, one end of which is rotatably connected to the driving assembly;

[0022] A driven shaft connected to the driving assembly by belt transmission;

[0023] The roller is sleeved on one end of the driven shaft close to the traction assembly.

[0024] Furthermore, two mutually parallel limiting plates are arranged on the mounting seat, and the limiting plates are sleeved on the driving assembly and abut against the supporting arm.

[0025] Further, the driving assembly includes a servo motor, which is detachably arranged on the mounting seat;

[0026] A driving shaft has one end connected to the power output shaft of the servo motor and is rotatably arranged on the mounting seat.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] A gastroscope traction device in the present invention, wherein the mounting seat plays a supporting role and a position limiting role for the arrangement of other parts of the structure. The driving assembly arranged on the mounting seat provides power for the operation of the cleaning assembly and the traction assembly, and plays a driving role. The cleaning assembly can clean and remove the body fluids adhered to the outer wall of the endoscope channel under the action of the driving assembly, and the traction assembly can pull and reel the cleaned endoscope channel under the action of the driving assembly, so that the endoscope channel can be smoothly and evenly recovered after the gastroscopy is completed, and the outer wall of the endoscope channel can be cleaned and disinfected at the same time to reduce the risk of cross contamination and increase the service life of the instrument. By installing the driving assembly and the mounting seat by bolt connection, the maintenance and replacement process of the driving assembly can be facilitated. By rotating the cleaning assembly on the mounting seat, the relative angle between the cleaning assembly and the mounting seat can be adjusted to adapt to different working conditions.

[0029] Secondly, by setting the traction component to a structure of a worm, a turbine, a driving wheel and a clamping wheel, the worm and the turbine transmission pair can not only transmit the torque output by the drive component to the driving wheel, but also realize the functions of deceleration and reversing. The turbine can drive the driving wheel to rotate under the meshing drive of the worm. The driven wheel, which is arranged on one side of the driving wheel and has an axial direction parallel to the axial direction of the driving wheel, can cooperate with the driving wheel to squeeze the outer wall of the endoscope, and drag the endoscope tube to move through the friction force of relative rotation, thereby realizing the traction action.

[0030] Thirdly, by introducing the box into the traction assembly, on the one hand, it plays a supporting and limiting role in the rotation of the worm, which is conducive to improving the stability of the transmission pair composed of the worm and the turbine, and on the other hand, it plays a protective role in the meshing part of the worm and the turbine. In addition, it also plays a supporting role in the setting of the driving wheel and the clamping wheel. By setting the clamping wheel to a structure that can be slidably arranged on the top of the box in the direction close to or away from the axis of the driving wheel, the size of the gap between the clamping wheel and the driving wheel can be adjusted according to the diameter of the outer wall of the endoscope pipe, which can ensure that the driving wheel and the clamping wheel can generate enough friction to pull the endoscope pipe to move, and will not cause damage to the endoscope pipe due to excessive pressure. At the same time, it can adapt to endoscopes of different models and sizes, thereby improving the scope of application of the present application. By setting a detachable handwheel on the end of the worm away from the driving assembly, the relevant personnel can adjust the relative position between the endoscope pipe and the traction assembly or provide power for the rotation of the driving wheel by turning the handwheel, so that it can be used normally in the absence of power. By arranging a guide plate on the top of the box, a guiding effect is played on the endoscope pipeline to prevent it from being entangled with other parts of the structure.

[0031] In addition, by configuring the cleaning component as a structure of a support arm, a driven shaft and a roller, the rotatably arranged support arm can be used to provide positioning and support for the installation of the driven shaft and the roller, and at the same time to adjust the relative position of the roller and the endoscope channel. The driven shaft can transmit torque to the roller by means of a belt drive connection. The roller can rotate with the driven shaft and remove dirt adhered to the outer wall of the endoscope channel by friction. By configuring the drive component as a structure consisting of a servo motor and a drive rod, the servo motor can provide precise speed and rotation direction adjustment to meet different working conditions. The drive shaft connected to the servo motor through a coupling can synchronously transmit torque to the cleaning component and the traction component, so that they can synchronously complete their respective functions.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0043] The following will refer to the attached Figure 1 To Attachment Figure 4 The present invention is described in detail with reference to embodiments.

[0044] The present embodiment relates to a gastroscope traction device, which can smoothly and evenly retract an endoscope tube after a gastroscopy is completed, and simultaneously clean and disinfect the outer wall of the endoscope tube to reduce the risk of cross contamination and increase the service life of the instrument.

[0045] In terms of overall structure, refer to Figure 1A gastroscope traction device of this embodiment includes a mounting seat 1, a driving assembly 2, a cleaning assembly 3 and a traction assembly 4. The driving assembly 2 is detachably arranged on the mounting seat 1 by bolt connection, and the cleaning assembly 3 is rotatably arranged on the mounting seat 1. The traction assembly 4 is fixedly mounted on the mounting seat 1. The cleaning assembly 3 and the traction assembly 4 are both connected to the driving assembly 2 and can move under the action of the driving assembly 2.

[0046] The mounting seat 1 plays a supporting role and a position limiting role for the arrangement of other parts of the structure. The driving assembly 2 arranged on the mounting seat 1 provides power for the operation of the cleaning assembly 3 and the traction assembly 4, and plays a driving role. The cleaning assembly 3 can clean and remove the body fluids adhered to the outer wall of the endoscope channel under the action of the driving assembly 2, and the traction assembly 4 can pull and reel the cleaned endoscope channel under the action of the driving assembly 2, so that the endoscope channel can be smoothly and evenly recovered after the gastroscopy is completed, and the outer wall of the endoscope channel is cleaned and disinfected at the same time to reduce the risk of cross contamination and increase the service life of the instrument. By installing the driving assembly 2 and the mounting seat 1 by bolt connection, the maintenance and replacement process of the driving assembly 2 can be facilitated. By rotating the cleaning assembly 3 on the mounting seat 1, the relative angle between the cleaning assembly 3 and the mounting seat 1 can be adjusted to adapt to different working conditions.

[0047] Reference Figure 1 and Figure 2 For the purpose of uniformly pulling the endoscope tube, in this embodiment, the traction assembly 4 includes a worm 401, a turbine 402, a driving wheel 403 and a clamping wheel 404. Among them, one end of the worm 401 is connected to the power output end of the driving assembly 2 through a coupling. The turbine 402 is meshed with the worm 401. The driving wheel 403 is coaxial with the turbine 402 and is relatively fixed. The clamping wheel 404 is located on one side of the driving wheel 403. The clamping wheel 404 can rotate around its own axis. The axis direction of the clamping wheel 404 is parallel to the axis direction of the driving wheel 403.

[0048] By setting the traction assembly 4 to a structure of a worm 401, a turbine 402, a driving wheel 403 and a clamping wheel 404, the transmission pair of the worm 401 and the turbine 402 can not only transmit the torque output by the drive assembly 2 to the driving wheel 403, but also realize the functions of deceleration and reversing. The turbine 402 can drive the driving wheel 403 to rotate under the meshing drive of the worm 401. The driven wheel, which is arranged on one side of the driving wheel 403 and whose axis direction is parallel to the axis direction of the driving wheel 403, can cooperate with the driving wheel 403 to squeeze the outer wall of the endoscope, and drag the endoscope tube to move through the friction force of relative rotation, thereby realizing the traction action.

[0049] Reference Figure 1 and Figure 2 , the traction component 4 also includes a box body 405. The box body 405 can be a hollow rectangular metal box with a removable box cover. The box body 405 is coated on the outside of the transmission pair composed of the turbine 402 and the worm 401. The worm 401 is rotatably arranged on the box body 405. The driving wheel 403 is rotatably arranged on the box cover. The clamping wheel 404 is arranged on the box cover of the box body 405 as a whole along the direction close to or away from the axis of the driving wheel 403, and can be fixed at any position within the relative sliding formation with the box body 405. A guide plate 406 is vertically installed on the top of the box body 405. The guide plate 406 is an arc-shaped plate. The distances from each point on the side of the guide plate 406 facing the driving wheel 403 to the axis of the driving wheel 403 are equal. The worm 401 arranged on the box body 405 extends to the outside of the box body 405 from one end away from the drive component 2. A hand wheel 407 is detachably mounted on one end of the worm 401 extending outside the box 405 , that is, the end of the worm 401 away from the driving assembly 2 , by means of a snap connection.

[0050] By introducing the box 405 into the traction assembly 4, on the one hand, it plays a supporting and limiting role in the rotation of the worm 401, which is conducive to improving the stability of the transmission pair composed of the worm 401 and the turbine 402, and on the other hand, it plays a protective role in the meshing part of the worm 401 and the turbine 402. In addition, it also plays a supporting role in the arrangement of the driving wheel 403 and the clamping wheel 404. By setting the clamping wheel 404 to a structure that can be slidably arranged on the top of the box 405 in the direction close to or away from the axis of the driving wheel 403, the size of the gap between the clamping wheel 404 and the driving wheel 403 can be adjusted according to the diameter of the outer wall of the endoscope pipe, which can ensure that the driving wheel 403 and the clamping wheel 404 can generate a sufficiently large friction force to pull the endoscope pipe to move, and will not cause damage to the endoscope pipe due to excessive pressure. At the same time, it can adapt to endoscopes of different models and sizes, thereby improving the scope of application of the present application. By providing a detachable hand wheel 407 at one end of the worm 401 away from the driving assembly 2, relevant personnel can adjust the relative position between the endoscope tube and the traction assembly 4 or provide power for the rotation of the driving wheel 403 by turning the hand wheel 407, so that it can be used normally in the absence of power. By providing a guide plate 406 on the top of the box 405, the endoscope tube is guided to prevent it from being entangled with other parts of the structure.

[0051] Reference Figure 1 and Figure 3, the cleaning assembly 3 includes a support arm 301, a driven shaft 302 and a roller 303. Among them, one end of the support arm 301 is sleeved on the power output end of the drive assembly 2, and is arranged to rotate relative to the drive assembly 2, and can rotate around the axis of the power output shaft of the drive assembly 2. The driven shaft 302 is arranged to rotate around its own axis direction on the end of the support arm 301 away from the drive assembly 2, and is connected to the power output end of the drive assembly 2 through a belt drive. The roller 303 is sleeved on the end of the driven shaft 302 close to the traction assembly 4. Two limit plates 101 are installed on the mounting seat 1. Both limit plates 101 are perpendicular to the mounting seat 1 and are arranged parallel to each other. The power output end of the drive assembly 2 is penetrated on the limit plate 101. The limit plate 101 is provided with a structure for limiting the rotation of the support arm 301, so as to avoid misalignment between the support arm 301 and the drive assembly 2.

[0052] By configuring the cleaning assembly 3 to be a structure of a support arm 301, a driven shaft 302, and a roller 303, the rotatably arranged support arm 301 can be used to provide position limiting and support for the installation of the driven shaft 302 and the roller 303, and to adjust the relative position of the roller 303 and the endoscope channel. The driven shaft 302 can transmit torque to the roller 303 by means of a belt drive connection. The roller 303 can rotate with the driven shaft 302, and remove dirt adhered to the outer wall of the endoscope channel by friction.

[0053] Reference Figure 1 and Figure 4 The driving assembly 2 includes a servo motor 201 and a driving shaft 202. The servo motor 201 is connected to the mounting seat 1 by bolts to realize a detachable mounting structure. The power output shaft of the servo motor 201 is connected to the driving shaft 202 by a coupling. The driving shaft 202 is passed through the limiting plate 101 and is connected to the cleaning assembly 3 and the traction assembly 4.

[0054] By configuring the drive assembly 2 as a structure consisting of a servo motor 201 and a drive rod, the servo motor 201 can provide precise speed and rotation direction adjustment to meet different working conditions. The drive shaft 202 connected to the servo motor 201 through a coupling can synchronously transmit torque to the cleaning assembly 3 and the traction assembly 4, so that they can synchronously complete their respective functions.

Although the present invention 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 invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
