Description

Novel stone extractor for hepatobiliary surgery

Technical Field

The utility model relates to a hepatobiliary surgery is with novel stone extractor belongs to hepatobiliary surgery and uses medical instrument technical field.

Background

With the improvement of living standard, the adjustment of dietary structure, the gradual popularization of physical examination and the like, the prevalence rate of gall bladder stones in China is gradually increased, and at present, the prevalence rate is more than 10%, so that the gall bladder stones become common diseases and frequently encountered diseases in China. Because gall-bladder stones can cause symptoms of digestive tracts such as abdominal distension and dyspepsia, serious patients induce biliary colic, complicated bile duct infection, obstructive jaundice, pancreatitis and the like, and are closely related to bile duct tumors, sufficient attention needs to be paid to treatment of the gall-bladder stones, early discovery and early treatment are achieved, and along with continuous development of modern science and technology and improvement of endoscope technology, people are prompted to focus again to protect gall-bladder stone removal operations, and stone extractors need to be used for extracting stones in the stone removal operations.

The existing stone extractor mostly adopts a stone extracting net to extract stones, large-particle stones are easily extracted in the whole stone extracting process, but small-particle stones which are difficult to observe by naked eyes can be omitted due to the relation of the net holes, so that the stones are easy to relapse. Traditional lithotomy forceps are taking out the in-process to the calculus, and the phenomenon of landing appears easily in the calculus, and medical personnel need to carry out the calculus repeatedly to this kind of phenomenon and get the operation to reach taking out smoothly to the calculus, if so then very easily cause the injury on the health to the patient in this operation, the device flexibility is relatively poor and its friction when wound department activity causes the problem of the secondary damage of wound department easily. The existing lithotomy forceps have a sharp clamping end and are easy to injure biliary tracts, and the area of the clamping end of the existing lithotomy forceps is small, so that the pressure on calculus is high, and therefore calculus is easy to crush, and calculus is remained on biliary tracts.

SUMMERY OF THE UTILITY MODEL

The utility model adopts the technical proposal that: designing a novel lithotomy device for hepatobiliary surgery, which comprises a forceps body I, a forceps body II hinged with the forceps body I, a spacer, a splint, a buckle plate, a retaining ring and a sleeve head; the stone extractor comprises a first clamp body and a second clamp body, wherein the first clamp body and the second clamp body are integrally formed, a separation pad is longitudinally and fixedly installed in the middle of the outer surface of the handle plate, the outer side of the separation pad is connected with a clamping plate through a first spring, a buckling groove is formed in the handle plate, the upper end of the buckling groove is connected with a buckling plate through a second spring, the buckling ring is installed at the upper end of the first clamp body, when the stone extractor is used, the thumb of a medical worker is buckled on the buckling ring, other fingers penetrate through a gap between the clamping plate and the handle plate and are buckled on the buckling plate to open or close the stone extractor, the forefinger is separated from the other fingers through the separation pad, the separation pad is clamped during use, the stone extractor is convenient to stably take the stone extractor, the middle upper portion of the fingers are clamped by the clamping plate, so that a hand is more firmly connected with the stone extractor and is not easy to fall off, the first spring connecting clamping plate and the buckling plate is adopted to adapt to personnel of different body types, the first clamp body and the second clamp body are respectively sleeved at the lower ends to conveniently replace different sleeve heads to adapt to different stones Meanwhile, the sleeve head material with large friction force can be selected to increase the friction force between the sleeve head material and the calculus and reduce the falling of the calculus.

Furthermore, the shock insulator is a rectangular plate, and the upper end and the lower end of the shock insulator are chamfered at two sides respectively to form a shuttle-shaped plate, so that the forefinger and the middle finger can be clamped stably.

Further, the buckle lower surface is provided with two at least arc walls, can only need thumb, forefinger and middle finger can operate the utility model discloses realize that the clamp of calculus is got, the arc wall is more convenient and the cooperation of finger.

Further, the buckle includes inner ring and outer loop, the inner ring includes two piece at least arcs, the inner ring passes through the third spring coupling with the outer loop, sets up an at least third spring between each arc and the outer loop of constituteing the inner ring, and the personnel of adaptable different sizes use, even the distractor of operating personnel also is difficult for droing simultaneously, improves the security greatly.

Furthermore, the inner side surface of the sleeve head is provided with a circular or oval groove, the edge of the groove is rounded, so that stones can be conveniently picked and contained, and the stones can be prevented from falling off in the taking-out process.

Furthermore, the sleeve head is elastic, the frictional resistance between the sleeve head and the calculus is larger, the calculus is more difficult to fall off by combining the deformation of the sleeve head when the calculus is clamped, and the damage to the human body is reduced.

Furthermore, the sleeve head is a silica gel sleeve head, so that the body of a patient is protected, and secondary damage is reduced.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a stone is got to pullover of silica gel material, and at the whole in-process of getting the stone, pullover is removable, and the convenient clamp of stone or the stone of small granule of large granule is got and is not omitted easily, avoids causing the stone relapse. The utility model discloses taking out the in-process to the knot stone, the stone is difficult to the landing, need not medical personnel and carries out the stone clamp repeatedly and get the operation, reduces the injury that causes on the health to the patient, and the device flexibility is higher, and the problem of the secondary damage of disease wound department obtains effective control. The utility model discloses a stone is got to the pullover of silica gel material, is difficult to injure the biliary tract, and the centre gripping end area is great, and is not high to the calculus pressure, and the calculus is difficult to be pressed from both sides the bits of broken glass, avoids the calculus to remain on the biliary tract.

The utility model has the advantages of slight trauma, less bleeding, low complication, saved operation cost and easy operation skill.
