Description

Ureteroscope injection treatment needle

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a ureteral nephroscope injection treatment needle.

Background

The urinary system organs (kidney, ureter, bladder, urethra) can develop diseases and spread over the whole system. When the urinary system diseases are checked or operated, related medical instruments are often required to be inserted into the urinary system cavity of a patient, and mucous membranes in the urinary system cavity of the patient are easily scratched in the process, even complications are caused, and pain is caused to the patient. Ureteroscope is a medical instrument for diagnosing and treating pathological changes of renal pelvis and ureter, and is required to be inserted into a patient to enter the ureter through urethra and bladder to complete examination and operation, however, no injection treatment needle for ureteroscope can be provided for assisting in treating the patient at present.

Disclosure of Invention

The utility model aims to provide a ureteroscope injection treatment needle so as to solve the problem that no injection treatment needle for ureteroscope can be provided in the prior art.

In order to achieve the above purpose, the present utility model provides the following technical solutions:

the basic technical scheme provided by the utility model is as follows: the ureteroscope injection treatment needle comprises a medical hose, the needle head is fixedly connected with the left end of the medical hose, the nut is fixedly connected with the right end of the medical hose, a guide cavity is axially arranged in the medical hose, a hard guide wire is arranged in the guide cavity in a penetrating mode, the left end of the guide wire is fixedly connected with the right end of the needle head, and the right end of the guide wire is fixedly connected with the right end of the medical hose.

Preferably, the top of medical hose left end fixedly connected with elastic connection spare, elastic connection spare's left end fixedly connected with elasticity visor.

Preferably, the upper end of the protective cover is fixedly connected with a clamping piece.

The principle and beneficial effect of this technical scheme are: the ureteroscope injection treatment needle can be connected with a matched injector through a nut at the right end of a medical hose, the shape of the ureteroscope injection treatment needle can be indirectly adjusted by adjusting the shape of a guide wire, and the ureteroscope is provided with an operation channel integrating flushing and operation, so that the ureteroscope injection treatment needle can be placed into the operation channel of the ureteroscope and inserted into a urinary system channel of a patient along with the ureteroscope, and can carry out drug injection treatment on mucous membranes or other deep tissues under the display of the ureteroscope. The design of the clamping piece can assist in fixing the position of the ureteral nephroscope injection treatment needle, the protective cover can protect a patient from being injured in the process that the ureteral nephroscope injection treatment needle enters a urinary system channel of the patient, and the design of the elastic connecting piece can facilitate medical staff to enable the needle head to be separated from the protective cover and smoothly perform injection treatment after the ureteral nephroscope injection treatment needle reaches a specified position in a patient. The utility model can be used for drug injection treatment under ureteroscope, ureteroscope and cystoscope.

Reference numerals in the drawings of the specification include: 1. a needle; 2. a medical hose; 3. a nut; 4. guiding the guide wire; 5. an elastic connection member; 6. a clamping piece; 7. a protective cover; 8. a guide lumen.

Detailed Description

The utility model is described in further detail below with reference to the attached drawings and embodiments:

as shown in fig. 1 to 3, the ureteroscope injection treatment needle comprises a medical hose 2, the left end of the medical hose 2 is fixedly connected with a needle head 1, the right end of the medical hose 2 is fixedly connected with a nut 3, a guide cavity 8 is axially arranged in the medical hose 2, a hard guide wire 4 is arranged in the guide cavity 8 in a penetrating manner, the left end of the guide wire 4 is fixedly connected with the right end of the needle head 1, and the right end of the guide wire 4 is fixedly connected with the right end of the medical hose 2. The top fixedly connected with elastic connection spare 5 of medical hose 2 left end, the left end fixedly connected with elasticity visor 7 of elastic connection spare 5, the outer wall of this visor 7 is the arc, can protect the point of syringe needle 1 to avoid the puncture patient with this ureteroscope injection treatment needle in-process of inserting patient's urinary system passageway. The upper end of the protective cover 7 is fixedly connected with a clamping piece 6 with an arc-shaped outer wall, so that the position of the ureteroscope injection treatment needle can be fixed in an auxiliary manner without damaging human tissues.

The specific implementation process is as follows:

when in use, after the injector matched with the ureteroscope injection treatment needle is filled with liquid medicine, the injector is connected with the matched injector through the nut 3 at the right end of the medical hose 2, and then the shape of the ureteroscope injection treatment needle is indirectly adjusted by adjusting the shape of the guide wire 4. The protective cover 7 is covered at the tip of the needle head 1 to prevent the ureteroscope injection treatment needle from injuring the patient during the process of entering the urinary system channel of the patient. Then the ureteroscope injection treatment needle is placed into the operation channel of the ureteroscope, the clamping piece 6 is clamped on the outer wall of the terminal of the operation channel of the ureteroscope, and the position of the ureteroscope injection treatment needle is assisted to be fixed, so that the ureteroscope injection treatment needle is prevented from moving at will. Then the ureteroscope injection treatment needle is inserted into a patient urinary system channel along with the ureteroscope, after reaching a designated position, the tail end of the medical hose 2 is slightly pulled backwards, the elastic connecting piece 5 is lengthened, the needle 1 can move backwards so as to separate from the protective cover 7, the protective cover 7 is contracted due to elasticity, then the needle 1 can be pushed out of the operation channel of the ureteroscope by moving the needle 1 forwards through the tail end of the medical hose 2, and the mucous membrane or other deep tissues can be subjected to drug injection treatment under the display of the ureteroscope. Besides ureteroscope, the utility model is also suitable for ureteroscope and cystoscope.

The foregoing is merely exemplary of the present utility model, and specific technical solutions and/or features that are well known in the art have not been described in detail herein. It should be noted that, for those skilled in the art, several variations and modifications can be made without departing from the technical solution of the present utility model, and these should also be regarded as the protection scope of the present utility model, which does not affect the effect of the implementation of the present utility model and the practical applicability of the patent. The protection scope of the present utility model is subject to the content of the claims, and the description of the specific embodiments and the like in the specification can be used for explaining the content of the claims.
