Description

Sleeve for endoscope and endoscope

Technical Field

The utility model belongs to the technical field of medical instrument, especially, relate to a sleeve pipe and endoscope for endoscope.

Background

With the continuous development of the endoscope technology, a minimally invasive treatment method is mostly adopted for treating ureteral calculus. Through a ureteroscope holmium laser is a high and new technology applied to urology surgery at the end of 20 centuries, and provides a new choice for minimally invasive treatment of ureteral calculus. The holmium laser lithotripsy through the ureteroscope can treat stones on the upper, middle and lower sections of the ureter, and has the advantages of high stone breaking efficiency, high stone removal rate, strong patient tolerance, short hospitalization time, small damage, capability of treating stones of bilateral ureters and the like. Ureteroscopy can also treat ureteral strictures, polyps, or perform a tumor biopsy.

The basis of ureteroscopy is successful endoscope entry, and the most critical is the entry of the ureteral opening. At present, a ureteral hard endoscope is clinically used for finding a ureteral opening, entering the endoscope and placing a guide wire, and then a guide sheath and a ureteral soft endoscope are placed for carrying out laser lithotripsy. The soft lens cannot directly enter the lens because the bending part of the soft lens is too soft and the directivity of the soft lens is not good. In the whole operation process, the hard lens needs to be switched into the soft lens, the operation process is complicated, and the equipment operation cost of the hospital is increased.

Furthermore, a branch slot is formed in the tube wall of the tube body along the length direction, and one end of the branch slot is connected to the other end of the tearing slot.

Furthermore, the opening depth of the sub-grooves is not larger than the thickness of the pipe wall of the pipe body.

Further, a heat-shrinkable sleeve is coaxially sleeved on the pipe body.

Furthermore, the pipe wall of the pipe body is fixedly connected with two handles, the handles are positioned at one end of the pipe body, which is provided with tearing grooves, and the two handles are arranged in an axial symmetry mode by taking the radius of the pipe orifice of the pipe body, which is perpendicular to the central line of the tearing groove.

An endoscope having the above-described endoscope sleeve includes a guide wire and the flexible endoscope, and the tube is fitted over an insertion portion of the flexible endoscope.

Further, the guide wire comprises a core rod, and the outer part of the core rod is coated with a coating layer.

Furthermore, both ends of the core rod are set to be cone-shaped structures.

Compared with the prior art, the sleeve for the endoscope realizes the switching of the soft lens and the hard lens in the whole operation process, and the sleeve can be used for supporting the soft lens to replace the hard lens, so that the operation process is simple, and the operation time is shortened. In addition, as no hard mirror is needed in the operation process, the operation cost of hospital equipment is reduced.

Example 1

Referring to fig. 1, the embodiment of the present invention provides a sleeve for an endoscope, including a tube body 1, wherein the tube body 1 is movably sleeved on an insertion portion of a soft lens 7 on the endoscope; a tearing groove 2 used for tearing the pipe body 1 is formed in the pipe wall of one end of the pipe body 1, and one end of the tearing groove 2 extends to the end portion of one end of the pipe body 1 to form an open end. The sleeve is designed to be tearable to facilitate peeling the hard sleeve from the soft lens insertion portion. The inner diameter of the hard sleeve is 3mm, the outer diameter is 3.5mm, the length is 20cm, and the hard sleeve is made of nylon 66.

Example 2

Referring to fig. 2, the present invention provides a sleeve for an endoscope, in addition to embodiment 1, a split groove 3 is further formed on a tube wall of a tube body 1 along a length direction, and one end of the split groove 3 is connected to the other end of a tearing groove 2.

When the pipe body 1 is made of soft materials such as plastics, the opening depth of the sub-open groove 3 is not more than the thickness of the pipe wall of the pipe body 1. The slotting 3 saves labor when tearing the sleeve, so that the sleeve can be easily torn.

When the tube body 1 is made of metal, the depth of the opening of the sub-slot 3 is equal to the thickness of the tube wall of the tube body 1, and the tube body 1 is a structure capable of being divided into two halves, so that the heat-shrinkable sleeve 4 needs to be coaxially sleeved on the tube body 1 to be combined into a tube shape.

Example 3

Referring to fig. 3, the embodiment of the present invention provides a sleeve for an endoscope, in which a handle 5 is fixedly connected to a tube wall of a tube body 1 based on embodiment 1, the handle 5 is located at one end of the tube body 1, which is provided with a tearing groove 2, the two handles 5 are arranged in axial symmetry with a tube orifice radius of the tube body 1 perpendicular to a central line of the tearing groove 2. The handle 5 is arranged to facilitate tearing the pipe body 1 for force application.

Referring to fig. 4 to 6, there is provided an endoscope having the above-described sleeve for an endoscope, including a guide wire 6 and the soft lens 7, wherein the insertion portion of the soft lens 7 is sleeved with the tube body 1.

Specifically, the guide wire 6 comprises a core rod 61, and the outer part of the core rod 61 is coated with a coating layer 62. Both ends of the core rod 61 are set to be cone-shaped structures. The length of the conical structure is preferably within 2cm, and the core rod 61 can be made of nickel titanium, stainless steel or the like. The coating 62 may be PTFE, TPU, PEBAX, nylon, or the like.

When in use, the ureter soft lens 7 is inserted into the bladder through the urethra to find the ureter opening. The sleeve is pushed to the soft bending part of the soft lens 7, so that the bending part of the soft lens 7 is hardened, and meanwhile, the guide wire 6 is inserted into the bending part of the soft lens 7. The ureteral opening was found by prying the cannula with a hand. After finding the ureteral opening, the guidewire 6 is pushed into the ureter. After the guide wire 6 is inserted into the ureter, the sleeve is pushed back to the handle part of the endoscope, and the ureter operation is continued. After the guide wire 6 is inserted into the ureter, the cannula may be withdrawn and separated into two halves to be detached from the insertion portion of the soft lens 7, and the ureter operation may be continued.

The above description is intended to be illustrative, and not restrictive, and one of ordinary skill in the art may effect alterations, modifications, substitutions, and variations to the above described embodiments while remaining within the scope of the present disclosure. Also, the above-described examples (or one or more versions thereof) may be used in combination with each other, and it is contemplated that the embodiments may be combined with each other in various combinations or permutations.
