Embodiment 1

[0030] like Figure 1 to Figure 4 As shown, a biliary curette used under laparoscopy in this embodiment includes a handle 1, a spoon head 2, a grip part 3, a corrugated hose section 4, a water retaining plate 5 and a water inlet tube 12; the grip part One end of 3 is connected to the water inlet pipe 12, the other end of the grip part 3 is rotationally connected to one end of the handle 1, the other end of the handle 1 is fixedly connected to the corrugated hose section 4, and the other end of the corrugated hose section 4 is detachable The spoon head 2 is provided; the connecting body of the handle 1 and the grip part 3 is provided with a first accommodation chamber 13 that penetrates through, the first accommodation chamber 13 communicates with the water inlet pipe 12, and the spoon head 2 is provided with a The second accommodating cavity 14 of the spoon head 2 is provided with a water retaining plate 5 at the front depression of the spoon head 2, and the water retaining pl...

Embodiment 2

[0034] like Figure 1 to Figure 4As shown, a laparoscopic biliary curette used in this embodiment includes all the technical features in Embodiment 1, in addition, it also includes a pulling protrusion 7, a guide sleeve 8, and a pulling rope 9 , tension button 10 and torsion spring 16; the pulling protrusion 7 is arranged on the outer peripheral side wall of one end of the corrugated hose section 4 close to the spoon head 2, and the guide sleeve 8 is arranged on the outer peripheral side wall of the handle 1 near the corrugated hose section 4 One end of the pull rope 9 is hooked on the pull protrusion 7, the other end of the pull rope 9 passes through the guide sleeve 8 and is connected with a tightening button 10, and the holding part 3 is provided with a snap-in groove 11, which is tightened. The button 10 is slidably arranged in the clamping groove 11; the middle part of the torsion spring 16 is sleeved on the outer peripheral side wall of the middle part of the corrugated ...

Embodiment 3

[0038] like Figure 1 to Figure 4 As shown, a laparoscopic biliary curette used in this embodiment includes all the technical features in Embodiment 2, in addition, it also includes a plurality of pulling springs 15, and one end of the pulling springs 15 is fixed At the bottom of the second accommodating chamber 14 , the other end of the pulling spring 15 is fixed on the end surface of the water baffle 5 near the second accommodating chamber 14 , and a plurality of pulling springs 15 are evenly distributed on the edge of the water baffle 5 .

[0039] The beneficial effects of this embodiment are: by arranging a plurality of uniformly distributed pulling springs 15, each position of the water retaining plate 5 is located in the same plane when the water retaining plate 5 is raised, and the maximum extension height of the water retaining plate 5 is limited. The backflow of stones is avoided; at the same time, the inconsistency of the height between the water retaining plate 5 an...

Abstract

The invention discloses a biliary tract curette used under a celioscope. One end of a grasping part is connected with a water inlet pipe, and the other end of the grasping part is rotatably connectedwith one end of a handle part; the other end of the handle part is fixedly connected with a corrugated hose section; a curette head is detachably arranged at the other end of the corrugated hose section; a penetrated first accommodating cavity is formed in a connector of the handle and the grasping part, and communicates with a water inlet pipe; a second accommodating cavity which communicates with the first accommodating cavity is formed in the curette head; a water baffle is arranged at a concave part of the front surface of the curette head, and is in elastic connection with the curette head; an annular water outlet which communicates with the second accommodating cavity is formed between the water baffle and the curette head; and the second accommodating cavity is formed in the back ofthe water baffle. The biliary tract curette used under a celioscope disclosed by the invention aims to solve the problems that in the prior art, in a celioscope operation, the head of the biliary tract curette cannot freely bend and cleaning of the head cannot be performed in an abdomen are solved; and the biliary tract curette has the effect that according to the path of the biliary tract, the corresponding entering direction of the curette head at the head is adjusted, so that self cleaning of the curette head at the head is realized.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a biliary curette used under a laparoscope. Background technique [0002] The use of biliary curettes is very important for the removal of intrahepatic bile duct stones. However, the existing biliary curettes are simple in design and fixed in shape, and are only suitable for open surgery. The main disadvantages in laparoscopic surgery are: the existing biliary curettes The head of the spoon cannot be bent freely; the head cannot clean itself in the abdominal cavity after scraping off the stones, and it needs to be taken out and cleaned. Repeated trips to and from the abdominal cavity will easily cause adverse effects on the operation; in summary, the existing biliary curette can be used in laparoscopic surgery It cannot be used or is extremely inconvenient to use, and it is only suitable for open biliary calculus surgery, and there is no related special biliary curett...
