Abstract
The utility model relates to an electric cutting mirror which comprises an endoscope, wherein the endoscope comprises a handle, a sheath tube and a lens, the sheath tube is fixedly connected with the handle, and the lens is arranged on the sheath tube; the lens is positioned in the sheath tube, and a step structure is formed between the mirror surface of the lens and the end surface of the sheath tube far away from the handle. The utility model can effectively reduce the adsorption of tiny tissues adhered on the electrode or the adhesion of the tiny tissues on the lens, and the endoscope is not required to be taken out of the body to wipe the lens, so that the operation time and the operation steps can be reduced, and the operation safety and the operation efficiency are improved.
Description
Technical Field
The utility model relates to an electrotome scope, and belongs to the technical field of medical appliances.
Background
The plasma electron microscope is a commonly used minimally invasive surgical medical instrument and is widely applied to the clinical treatment of prostatic hyperplasia, bladder tumor, urethral stricture, the surgical treatment of some gynecological diseases and the like.
The resectoscope is generally composed of an endoscope, an inner sheath, an outer sheath, a handle, other accessories (including electrodes) and the like, and plays roles of supporting and fixing the electrodes. The endoscope is constructed by referring to Chinese patent publication No. CN115399866A (application date: 2022, 08, 23, and named as "a soft endoscope structure for lower urinary tract operation"), and a lens is mounted at the front end of the sheath tube, so that an operation can be performed by viewing a cutter head of the plasma electrode through the endoscope.
The applicant finds that the lens mirror surface of the existing endoscope is of a plane structure in the research and development and sales processes, so that when an operation is performed, tiny tissues adhered on an electrode ring can be adhered on the lens mirror surface of the lens, and as the operation time is prolonged, more tissues are increased, so that the field of view is blurred, and even when the operation is serious, the endoscope needs to be taken out of the body to wipe the lens, thereby increasing the operation time and operation steps, not only being unfavorable for the safety of the operation of a patient, but also reducing the operation efficiency.
Disclosure of Invention
The utility model aims to solve the technical problems that: an resectoscope is provided which can increase the definition of the visual field of a lens, thereby improving the operation efficiency.
In order to solve the technical problems, the utility model provides an electrotome scope which comprises an endoscope, wherein the endoscope comprises a handle, a sheath tube and a lens, the sheath tube is fixedly connected with the handle, and the lens is arranged on the sheath tube; the lens is positioned in the sheath tube, and a step structure is formed between the mirror surface of the lens and the end surface of the sheath tube far away from the handle.
The lens end face of the endoscope is arranged in the sheath tube, and a recessed step structure is formed between the lens end face and the sheath tube end face, so that tiny tissues stuck on the electrode can be effectively reduced to be adsorbed or stuck on the lens in the operation process, and even if a small amount of human tissues are close to the lens, the small tissues can be basically hung on the sheath tube end face at the edge of the step structure and are not stuck on the surface of the lens any more; at this time, tissues hung on the end face of the sheath tube at the edge of the step of the bench structure can be removed by reciprocating the electrotome, so that the endoscope does not need to be taken out of the body to wipe the lens.
Drawings
The utility model is further described below with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of an electrotome in an embodiment of the present utility model.
Fig. 2 is a schematic view of the position of a lens in an endoscope.
Reference numerals: 1. a handle; 2. a sheath; 3. a lens; 4. a handle; 5. an electrode connection pipe; 6. a plug; 7. a socket; 8. an electrode; 9. an outer sheath; 10. and a host.
Detailed Description
Example 1
The embodiment relates to an endoscope, as shown in fig. 1 and 2, comprising a handle 1, a sheath tube 2 and a lens 3, wherein the sheath tube 2 is fixedly connected with the handle 1, the lens 3 is arranged on the sheath tube 2, the lens 3 and the sheath tube 2 are preferably in threaded connection or are glued joint, and the sheath tube 2 can be made of various materials, preferably stainless steel. As shown in fig. 2, the lens 3 is located inside the sheath tube 2, and an inward step structure is formed between the mirror surface of the lens 3 and the end surface of the sheath tube 2 away from the handle 1. In the operation process, when the resectoscope is in a pushing state, the electrode 8 and the sheath tube 2 extend out of the inner sheath (this is the prior art, not shown in the figure), and by adopting the endoscope structure of the embodiment, tiny tissues adhered on the electrode 8 can be effectively reduced from being adsorbed or adhered on the lens, because even if a small amount of human tissues are close to the lens 3, the tissues can be basically hung on the end face of the sheath tube 2 at the edge of the step structure, and the tissues are not adhered on the surface of the lens 3 any more, so that the endoscope is not required to be taken out of the body to wipe the lens any more, and the operation time and the operation steps can be reduced.
The present embodiment can also be modified as follows:
1) As shown in fig. 2, the end surface of the sheath tube 2 away from the handle 1 is an inclined surface, and the mirror surface of the lens 3 is parallel to the end surface of the sheath tube 2 away from the handle 1. In this way, the endoscope can conveniently pass through the natural duct of the human body.
2) The distance between the mirror surface of the lens and the end surface of the sheath tube far away from the handle is 0.4-2cm. Thus, the effect of the lens can be ensured, and the adhesion of the tiny tissues adhered on the electrode 8 to the lens can be avoided.
Example two
The embodiment relates to an electric cutting scope, as shown in fig. 1, which comprises an endoscope, an inner sheath (not shown in the figure), an outer sheath 9, a handle 4, an electrode 8 and other accessories, wherein the electrode 8 is inserted into an interface 7 on a host 10 through a plug 6 on an electrode connecting pipe 5 and is connected with the host 10. Wherein the endoscope is as described in embodiment one.
Claims (5)
1. An electric cutting mirror is characterized in that: the endoscope comprises a handle, a sheath tube and a lens, wherein the sheath tube is fixedly connected with the handle, and the lens is arranged on the sheath tube; the lens is positioned in the sheath tube, and a step structure is formed between the mirror surface of the lens and the end surface of the sheath tube far away from the handle.
2. The resectoscope according to claim 1, wherein: the end face of the sheath tube, which is far away from the handle, is an inclined plane, and the mirror face of the lens is parallel to the end face of the sheath tube, which is far away from the handle.
