Description

Technical Field

[0001] The utility model relates to the technical field of endoscope joints, in particular to a medical endoscope joint. Background Art

[0002] A medical endoscope is a medical device that can enter the body to observe tissues and organs, including gastroscopes, colonoscopes, laparoscopes, laryngoscopes, bronchoscopes, and cystoscopes. A medical endoscope usually consists of a flexible hose, a lens, and a light source. The doctor inserts the endoscope into the body and observes the internal organs and lesions on the screen through the flexible hose and lens of the endoscope, so as to make a diagnosis and treatment.

[0003] At present, medical endoscopes on the market have added a water injection function to facilitate gastrointestinal surgery and examination. Therefore, when using it, it is necessary to first connect the medical endoscope to the water pump through a water supply connector so that subsequent work can proceed normally. However, during the use of the existing medical endoscope water supply connector, the liquid in the patient's digestive tract can easily flow back through the endoscope water outlet under the action of pressure, thereby contaminating other medical equipment and affecting the subsequent work. In addition, when the endoscope is inserted into the patient's body, sometimes some substances will adhere to the endoscope lens. For example, during colonoscopy, the patient's intestinal preparation is poor, and a small amount of feces is easy to adhere to the endoscope lens, thereby affecting observation. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] In view of the above-mentioned problems of the medical endoscope joint, the present utility model is proposed.

[0006] Therefore, the purpose of the utility model is to provide a medical endoscope connector, which is used to solve the problem that during the use of the existing medical endoscope water supply connector, the liquid in the patient's digestive tract is easily backflowed through the water outlet of the endoscope under the action of pressure, thereby causing pollution to other medical equipment and affecting the subsequent work. In addition, when the endoscope is inserted into the patient's body, sometimes some substances will adhere to the lens of the endoscope. For example, during colonoscopy, the patient's intestinal preparation is poor, and a small amount of feces is easily attached to the lens of the endoscope, thereby affecting observation.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a medical endoscope connector, comprising:

[0028] Reference Figure 1-Figure 3 , which is an embodiment of the utility model, provides a medical endoscope connector, which includes: a main unit 100 and a flushing unit 200;

[0029] The main unit 100 includes a connector 101 and a tube body 102, and the connector 101 and the tube body 102 are fixed and connected;

[0030] The flushing unit 200 includes a plurality of flushing holes 201 opened in the tube body 102, and one end of the flushing hole 201 is connected to the tube body 102, and the other end of the flushing hole 201 is connected to the outside world. A plurality of flushing holes 202 are opened in the tube body 102 at equal intervals along its radial direction, and one end of the flushing hole 202 is connected to the tube body 102, and the other end of the flushing hole 202 is connected to the outside world. A piston 203 is sealed and slidably connected in the tube body 102, and the piston 203 can block the openings of one end of the flushing hole 201 and the flushing hole 202.

[0031] In addition, piston 1 203 divides the interior of the tube body 102 into chamber 1 208 and chamber 2 209, and chamber 2 209 is connected to the connector 101. A plurality of guide cylinders 205 are fixed in the tube body 102, and piston 210 is sealingly and slidably connected in the guide cylinder 205. A guide rod 206 is fixed to one side of the piston 210, and the plurality of guide rods 206 are respectively slidably fitted in the corresponding guide cylinders 205. One end of the guide rod 206 away from the piston 210 is fixed to the piston 1 203. A spring 207 is sleeved on the outer side of the guide rod 206, and one end of the spring 207 is against the piston 1 203, and the other end of the spring 207 is against the guide cylinder 205.

[0032] When in use, the connector is a water supply connector on a medical endoscope. When flushing is required, an external water source presses piston 1 203 to drive piston 1 203 to move. When piston 1 203 no longer blocks flushing hole 202, flushing water is discharged from flushing hole 202 to flush the patient's tissue. When flushing is not required, the rebound force of spring 207 drives piston 1 203 to move in the opposite direction, so that piston 1 203 blocks one end of flushing hole 202, thereby preventing the patient's body fluids from entering the medical endoscope and causing contamination.

[0033] In addition, a retaining ring 204 is fixed to the inner wall of the tube body 102, and the retaining ring 204 is located in the second chamber 209, the inner ring diameter of the retaining ring 204 is smaller than the outer diameter of the piston 1 203, the vertical cross-section of the flushing hole 1 201 is in a "z" shape, the vertical cross-section of the flushing hole 202 is in an "L" shape, and the distance H1 from the end where the flushing hole 1 201 and the tube body 102 are connected to the end where the flushing hole 202 and the tube body 102 are connected is equal to half of the height H2 of the piston 1 203. When the spring 207 is in the normal state, the piston 1 203 blocks the ends where the flushing holes 1 201, the flushing holes 202 and the tube body 102 are connected, and the arc length between the first and last two flushing holes 201 among the multiple flushing holes 201 is one sixth of the outer circumference of the tube body 102.

[0034] When in use, different flushing functions can be achieved by changing the water pressure of the flushing water. When the flushing water pressure drives the piston 203 to move, the piston 203 no longer blocks the flushing hole 201 and the flushing hole 202. At this time, the flushing water can be discharged from the flushing hole 201 and the flushing hole 202, so that the endoscope lens and the patient's tissue can be flushed. When the flushing water pressure drives the piston 203 to move, the piston 203 no longer blocks the flushing hole 201 but continues to block the flushing hole 202. At this time, the flushing water will only be discharged from the flushing hole 201, so that only the endoscope lens can be flushed.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
