Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a lubricating sleeve for a disposable endoscope. Background Technology
[0002] Endoscopes have wide applications in urology, especially in male urological surgery, where they can enter the body through natural orifices (the penile urethra). The existence of natural orifices has greatly facilitated the widespread adoption of endoscopic surgical techniques in urology. Various models of endoscopes combined with handpieces are available, and different endoscopes have been developed for different surgical procedures, such as electrocautery endoscope handpieces, laser endoscope handpieces, urethrotomy endoscopes, and percutaneous nephrolithotomy endoscopes.
[0003] Currently, endoscopic handpieces are inserted into the human body through the urethra. Although the diameter of endoscopes and their handpieces can be made smaller with the advancement of technology, they are still relatively large compared to the diameter of the urethra. This is especially true for patients with urethral stricture. When passing through the urethra, the tip of the endoscope can easily cause damage to the urethra, thus harming the patient.
[0004] In practical applications, the obturator is first inserted into the endoscope sheath, and then inserted into the urethra and bladder together. The water inlet of the sheath and the seam between the sheath and the obturator can damage the urethral mucosa. Although the tips of the endoscope sheath and obturator can be ground and deburred to the maximum extent, and the size can be made smaller and smaller, the uneven surface of the water inlet of the rigid endoscope sheath and the seam between the sheath and the obturator can still damage the urethral mucosa when inserted into the urethra, especially in patients with urethral stricture. Utility Model Content
[0005] The purpose of this invention is to provide a lubricating sleeve for a disposable endoscope. The lubricating sleeve covers the outer periphery of the endoscope, so that the endoscope can avoid damaging the urethral mucosa after entering the natural cavity of the human body. When the endoscope reaches the site to be examined, the lubricating sleeve can be easily torn off and removed from the natural cavity.
[0006] The lubrication sleeve for a disposable endoscope includes:
[0007] The front part of the sheath is used to cover the endoscope. The front part of the sheath is cylindrical and has a tear line that extends along the axial direction of the cylindrical sheath.
[0008] The middle part of the sleeve is located at the end of the front part of the sleeve and is connected to the front part of the sleeve; the middle part of the sleeve is in communication with the front part of the sleeve.
[0009] The rear part of the sleeve is located at the end of the middle part of the sleeve and is connected to the middle part of the sleeve. The rear part of the sleeve is a conical sleeve and is connected to the middle part of the sleeve.
[0010] The notch is formed in the middle part of the sleeve and the side wall of the rear part of the sleeve, and extends along the end of the rear part of the sleeve to the front end of the middle part of the sleeve;
[0011] The notch allows the tear line to break, thus releasing the front of the sheath from the endoscope.
[0012] As a preferred embodiment of a lubrication sleeve for a disposable endoscope, the notch is V-shaped at the end furthest from the rear of the sleeve.
[0013] As a preferred embodiment of a lubrication sleeve for a disposable endoscope, the notch is U-shaped at the end furthest from the rear of the sleeve.
[0014] As a preferred embodiment of a lubricating sleeve for a disposable endoscope, the lubricating sleeve is made of nitrile rubber or latex.
[0015] As a preferred embodiment of a lubrication sleeve for a disposable endoscope, the outer wall of the sleeve can be coated with a lubricant.
[0016] As a preferred embodiment of a lubricating sleeve for a disposable endoscope, the front end of the sleeve, away from the middle of the sleeve, is spherical.
[0017] Beneficial effects: In this invention, by covering the endoscope at the front of the sheath, the operator avoids scratching or cutting the mucous membrane of the patient's natural cavity when introducing the endoscope into the patient's body. At the same time, through the tear line structure, after the endoscope is introduced into the patient's natural cavity and reaches the designated examination site, the operator can further pull outward on the conical part at the rear of the sheath, causing the lubricating sleeve to break along the tear line along the notch, and releasing the front of the sheath from the endoscope, making it easier to tear the lubricating sleeve and remove it from the urethra, ensuring that the operator can perform subsequent endoscopic examinations.

[0035] Please see the appendix Figure 1 -Appendix Figure 7 In this embodiment, the lubrication sleeve of the disposable endoscope includes: a front sleeve 100, a middle sleeve 200, and a rear sleeve 300. The front sleeve 100 is used to cover the endoscope 10 and is a cylindrical sleeve with a tear line 110 extending along the axial direction of the cylindrical sleeve. The middle sleeve 200 is located at the end of the front sleeve 100 and is connected to it, communicating with the front sleeve 100. The rear sleeve 300 is located at the end of the middle sleeve 200. It is connected to the middle part 200 of the sleeve body, and the rear part 300 of the sleeve body is a conical sleeve body, which is connected to the middle part 200 of the sleeve body; the notch 400 is opened on the side wall of the middle part 200 and the rear part 300 of the sleeve body, and extends along the end of the rear part 300 to the front end of the middle part 200 of the sleeve body; the notch 400 can break the tear line 110 so that the front part 100 of the sleeve body can release the endoscope 10 from its covering.
[0036] In this embodiment, the endoscope 10 is covered by the front part 100 of the sheath, so that when the operator introduces the endoscope 10 into the natural cavity of the patient's body, the endoscope lens tip 11 of the endoscope 10 can scratch or cut the mucosa of the natural cavity. The rear part 300 of the sheath is conical to avoid the endoscope handpiece tip 12. At the same time, after the operator introduces the endoscope 10 into the natural cavity of the patient's body and reaches the area to be examined by the patient, the operator further pulls the conical part of the rear part 300 outward to break the lubricating sleeve along the tear line 110 along the notch 400, and removes the front part 100 from the endoscope 10, so as to facilitate tearing the lubricating sleeve and removing the lubricating sleeve from the patient's natural cavity, so as to ensure that the operator can perform subsequent examinations with the endoscope 10.
[0037] Optionally, the notch 400 is V-shaped at the end away from the rear part 300 of the sleeve. Specifically, the sharp corner of the V-shape is connected to the tear line 110. When the notch 400 causes the tear line 110 to break, the tear line 110 can start to tear along the sharp corner of the V-shape, ensuring that the starting end of the tear line 110 is stably torn apart.
[0038] Optionally, the notch 400 is U-shaped at the end away from the rear part 300 of the sleeve. Specifically, the bottom arc edge of the U-shape is connected to the tear line 110, which can also ensure that when the notch 400 causes the tear line 110 to break, the tear line 110 starts to tear along the bottom arc edge of the U-shape, ensuring that the starting end of the tear line 110 is stably torn off.
[0039] Preferably, the material of the lubricating sleeve is nitrile rubber or latex. Nitrile rubber or latex is easy to mold, has stable performance, and is non-toxic.
[0040] Alternatively, the lubrication sleeve may also be made of plastic.
[0041] Optionally, to further ensure that the lubricating sleeve can be introduced into the patient's body more smoothly, the outer wall of the lubricating sleeve can be coated with lubricant.
[0042] Optionally, the end of the front portion 100 of the sheath, away from the middle portion 200, is spherical. This spherical shape makes the covering surface of the front portion 100 smoother, facilitating easier insertion into the patient's body and improving the patient's treatment experience, while significantly minimizing damage to the mucosa of the patient's natural cavities. Of course, those skilled in the art can also make the covering surface of the front portion 100 planar. Furthermore, to ensure a smooth transition between the covering surface and the cylindrical surface of the front portion 100, a rounded corner transition can be used.
[0043] Preferably, the front part 100, the middle part 200, and the rear part 300 of the sleeve are integrally formed.
[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
