Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an electronic ureter endoscope.
Background
Clinical in vivo examination and visual surgical treatment require a sharp image endoscope to help the doctor improve the accuracy of diagnosis. The medical endoscope is a detection and treatment instrument integrating optics, electricity, precision machinery and software into a whole, and is provided with an image transmission assembly, an optical or electronic imaging module, a cold light source or an LED electronic light source, a mechanical device and the like, and the medical endoscope can enter the body through a natural pore canal and can see pathological changes which cannot be displayed by X rays and ultrasound, so the medical endoscope is very useful for improving the medical quality, and many diseases need to be examined, diagnosed and treated through the endoscope, such as diseases at trachea, esophagus, stomach, intestine, bladder and the like. Ureteroscopy is a procedure in which an endoscope with a diameter of about 3mm is inserted into a ureter through the urethra and bladder to break up ureteral stones or kidney stones and take them out. It utilizes the natural urinary system cavity of human body, does not make any incision on the human body, and is a pure urinary surgery endoscopic minimally invasive surgery.
In the ureter soft lens operation, the ureter soft endoscope can enter the body through the urethra to observe the lesion position and can be matched with a surgical instrument to perform visual operation treatment in the body. In the existing ureteroscope operation, a sheath-entering expansion pipe is usually matched with a ureteral sheath to carry out sheath-feeding operation, then a ureteroscope catheter is inserted into the ureteral sheath to treat an affected part, in the broken calculus-removing operation process of urinary surgery, broken calculus which is beaten by holmium laser needs to be discharged out of a body through the ureteral sheath, at the moment, the ureteroscope catheter needs to be withdrawn for operation, but the discharge condition of the broken calculus cannot be observed due to withdrawing of the ureteroscope catheter, so that the broken calculus cannot be completely discharged out of the body at one time, in order to ensure the operation effect, the ureteroscope catheter needs to be inserted for observation or treatment for many times, so that the repeated operation of inserting the ureteroscope catheter increases the pain of a patient, and simultaneously, the injury of human organs is easily caused.
Disclosure of Invention
In order to solve the technical problems, the invention provides an electronic ureteroscope which comprises a camera sub-scope and a therapeutic sub-scope, wherein the camera sub-scope and the therapeutic sub-scope can be mutually embedded, insertion tubes of the camera sub-scope and the therapeutic sub-scope are both in a semi-tubular structure, the two semi-tubes are mutually embedded to form the insertion tube for use before calculus breaking is completed, and after calculus breaking is completed, the therapeutic semi-tube is withdrawn for carrying out calculus removing operation.
The technical scheme of the invention is as follows:
the utility model provides an electron ureteroscope, the endoscope includes the son mirror of making a video recording and treats the son mirror, the son mirror of making a video recording reaches the son mirror of treatment can gomphosis each other, the son mirror of making a video recording reaches the intubate of treating the son mirror is half tubular structure, make a video recording half pipe with the half pipe of treatment can gomphosis each other, illumination passageway and the passageway setting of making a video recording are in the half pipe of making a video recording, and the working channel setting is in the half pipe of treatment.
Furthermore, the tube walls of the image pick-up half tube and the treatment half tube are made of soft resin materials.
Furthermore, the cross section of the insertion tube formed by the embedded camera shooting half tube and the embedded treatment half tube is circular. Optionally, the cross sections of the image pickup half tube and the treatment half tube are both semicircular. Optionally, the cross section of the image pickup half tube is circular, and the cross section of the treatment half tube is hollow circular. Optionally, the cross section of the image pickup half tube is elliptical, and the cross section of the treatment half tube is hollow and circular.
Furthermore, the operation handles of the image pickup sub-mirror and the treatment sub-mirror can be mutually embedded. Before the use, two operating handle pass through the locking piece gomphosis together, after the rubble is accomplished, remove the locking, will half pipe of treatment withdraws from the tube sheath, and the row of stone is accomplished, again will half pipe of making a video recording withdraws from the tube sheath.
Further, the cross-sectional area of the tip of the imaging half-tube is larger than that of the insertion tube, and the cross-sectional area of the tip of the treatment half-tube is smaller than that of the insertion tube. After the gravel is finished, the treatment half-tube is withdrawn from the tube sheath, and the camera half-tube is inserted forwards to protrude out of the tube sheath opening, so that the diameter of the calculus removing tube can be increased, and the gravel can be better discharged.
Furthermore, the joint part of the image pick-up half tube and the treatment half tube is coated with light viscous materials. Before the use, two half pipes can be fixed together, and it is more convenient to insert, and behind the rubble, two half pipes can alternate segregation under less dynamics.
Further, the endoscope is used in cooperation with an expansion sheath, and the expansion sheath is sleeved outside an insertion tube of the endoscope.
