Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to a get stone basket for hard mirror holmium laser lithotripsy operation.

Background

In recent years, ureteroscope lithotripsy is increasingly performed, in the traditional ureteroscope lithotripsy, when a calculus is sleeved by a calculus-taking basket, the lens needs to be withdrawn, the optical fiber is inserted into the lens again, if the calculus is sleeved for a plurality of times, the lens needs to be advanced and withdrawn for a plurality of times, the position of the optical fiber is difficult to control, a plurality of time is needed for adjusting the position of the optical fiber in the operation, the operation treatment time is long, meanwhile, the repeated lens causes a plurality of times of friction damage to the ureteral wall, in addition, the end part of the inserted laser optical fiber is difficult to position, the laser easily causes a plurality of times of burns to the mucous membrane in the ureter of a patient, the corresponding part generates edema and damage, the ureter forms scars, the ureter is narrow, the pain of the patient is increased, and if the operation is not proper, the laser can break the basket. Therefore, on the premise of accurate lithotripsy, how to quickly and accurately position the optical fiber and simplify the operation steps so as to shorten the operation treatment time, relieve the pain of a patient and reduce the occurrence of medical accidents is a problem to be solved.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome the not enough of prior art existence, provide a get stone basket for hard mirror holmium laser stone breaking operation, the utility model discloses a get the accurate calculus that smashes of position that stone basket can fix the calculus and be convenient for control optic fibre in the operation, can effectively prevent to lead to the holmium laser to hit the problem of breaking the basket because of the misoperation, need not to go into the mirror repeatedly, simplified operating procedure, have can shorten operation treatment time, alleviate patient's misery, reduce the advantage that medical accident takes place.

In order to solve the technical problem, the utility model provides a technical scheme does:

the utility model provides a get stone basket for hard mirror holmium laser lithotripsy operation, includes basket sheath pipe, inner core and basket seat, be equipped with input and output on the basket seat, the inside of basket seat be equipped with the intercommunication passageway of input and output intercommunication, the basket sheath pipe is linked together with the output of basket seat, and the input of basket seat is including being used for supplying inner core male inner core passway and being used for supplying optical fiber male fibre channel mouth, the inner core passes through inner core passway and intercommunication passageway wear to locate in the lumen of basket sheath pipe, one of inner core near the basket sheath pipe is served and is equipped with the basket head that is used for emboliaing the pinning calculus. When in use, one end of the inner core extends out of the basket sheath, the basket head is opened to be capable of sleeving, locking and fixing the stone, after the stone is fixed, the holmium laser fiber passes through the fiber passage port, the communication passage and the basket sheath and finally extends out of the basket sheath, because the inner core and the fiber are both arranged in the lumen of the basket sheath, the restriction effect of the lumen inner wall of the basket sheath only allows the relative horizontal movement of the inner core and the fiber, thereby having the restriction effect on the relative position of the inner core and the fiber, ensuring that the laser fiber can reach the central position of the basket head to accurately crush the stone as far as possible, and the basket sheath can restrict the position of the fiber, so that the position of the fiber is convenient to control in the operation process, the time for adjusting the position of the fiber is shortened, the operation time is shortened, and simultaneously the problems that the laser breaks the basket head or burns the mucous membrane in the ureter of a patient due to inaccurate adjustment of the position of the fiber, the pain of the patient is relieved, and the occurrence of medical accidents is reduced.

Preferably, the communicating channel between the inner core channel opening and the output end of the basket base and the lumen of the basket sheath tube are positioned on the same straight line. This structure can guarantee that the inner core also keeps the straight line to extend in intercommunication passageway and basket sheath pipe, and the inner core of being convenient for is adjusted at length direction because the tip of inner core is equipped with the basket head, and the elasticity of calculus is packed up and entangled to opening of basket head to the motion direct relation of inner core on length direction, consequently sets up to the straight line and avoids appearing buckling the regulation of influence to the basket head.

Preferably, the angle between the communicating channel at the opening of the inner core channel and the communicating channel at the opening of the optical fiber channel is theta, and theta is larger than or equal to 12 degrees and smaller than or equal to 60 degrees.
